2    
3      * Real-time instrument scripts:
4        - Fix: Do not share compiled instrument scripts among multiple engine
5          channels (sampler parts) as this can lead to crashes and would allow the
6          same global script variables to be accessible from multiple engine
7          channels which would not be the expected behaviour by instrument script
8          authors.
9    
10      * GigaStudio/Gigasampler format engine:
11        - Use libgig's new IO-per-thread feature to avoid file I/O concurrency
12          issues with .gig file.
13        - Use libgig's new method gig::File::GetSample() with method
14          gig::File::CountSamples() instead of now deprecated
15          gig::File::GetFirstSample() / gig::File::GetNextSample() pair.
16        - Use libgig's new method gig::Instrument::GetRegionAt() with method
17          gig::Instrument:CountRegions() instead of now deprecated
18          gig::Instrument::GetFirstRegion() / gig::Instrument::GetNextRegion() pair.
19        - Use libgig's gig::File::GetInstrument() method with method
20          gig::File::CountInstruments() instead of now deprecated
21          gig::File::GetFirstInstrument() / gig::File::GetNextInstrument() pair.
22    
23      * MIDI driver:
24        - VirtualMidiDevice: added method Reset() which is e.g. intended to be used
25          in "panic" / MIDI "all sound off" / MIDI "all note off" situations.
26        - VirtualMidiDevice: release all notes on MIDI CC #120 and CC #123.
27    
28    Version 2.2.0 (9 May 2021)
29    
30      * general changes:
31        - Fixed compiler error in Pool.h.
32        - Require C++14 compiler support.
33        - Autoconf: Added m4/ax_cxx_compile_stdcxx.m4 macro which is used
34          for checking in configure for C++14 support (as mandatory
35          requirement) and automatically adds compiler argument if required
36          (e.g. -std=C++14).
37        - RTMath: Implemented floating point comparison methods
38          fEqual32(float,float) and fEqual64(double,double) which take the
39          expected floating point tolerances into account.
40        - Added public API C++ class "LFO", which is a cluster class encapsulating
41          all the sampler's LFO implementations to be used by 3rd party applications
42          (e.g. by Gigedit).
43        - Added int math square LFO implementation.
44        - Added int math saw LFO implementation.
45        - Added numeric complex nr sine LFO implementation.
46        - Marked class LFOTriangleDiHarmonic as deprecated
47          (will be removed in future).
48        - Added LFOAll.h which includes all LFO implementation's header files.
49        - Refactored LFO class names and their file names (PulseLFO -> LFOPulse,
50          LFOSawIntMath -> LFOSawIntMathNew, SawLFO -> LFOSawIntMathOld,
51          SineLFO -> LFOSineBuiltinFn, LFOSine -> LFOSineNumericComplexNr,
52          SquareLFO -> LFOSquarePulse and separated the latter to its own header
53          file).
54        - Renamed type LFOSigned -> LFOTriangleSigned.
55        - Renamed type LFOUnsigned -> LFOTriangleUnsigned.
56        - Using now cubic interpolation as resampling algorithm by default; and
57          linear interpolation is deprecated now.
58        - Event:Init(): memset() entire Event::Param union to zero instead of trying
59          to do that for its individual members; the latter became error prone due
60          to the union's growing complexity meanwhile.
61        - EngineChannel: Overhaul of RPN/NRPN related methods: Added new
62          *Rpn*Parameter*() methods as replacement for previous *Rpn*Controller*()
63          methods and marked the old ones as deprecated; and likewise added new
64          *Nrpn*Parameter*() methods as replacement for previous *Nrpn*Controller*()
65          methods and marked those old ones deprecated as well.
66        - Added support for MIDI CC #38 (data entry LSB): this allows higher value
67          resolution for certain (e.g. hard coded) RPN and NRPN parameters.
68        - Implemented support for compressed RPN/NRPN message sequences (that is to
69          allow processing MIDI data entry messages without always having to be
70          preceded strictly by RPN/NRPN parameter selection messages on each value
71          change).
72        - Added support for MIDI CC #96 (data increment) and MIDI CC #97 (data
73          decrement).
74        - Added support for 'null function RPN/NRPN' (which is RPN/NRPN parameter
75          MSB=127 and LSB=127) and which is disabling subsequent data
76          entry/increment/decrement CC messages.
77        - Fixed crash when editing key groups (a.k.a. exclusive groups) with an
78          instrument editor.
79        - Fixed playing noise at the end of a disk stream under certain conditions.
80        - Fixed potential crash with high pitch at end of RAM playback.
81        - Added configure checks whether C++ compiler supports so called
82          'designated initializers'.
83        - Added global backtraceAsString() function for debugging purposes
84          (POSIX systems only, no Windows implementation yet).
85        - Thread class: Added new methods pushCancelable(), popCancelable(), name(),
86          nameOfCaller() and setNameOfCaller().
87        - configure: Always check for availability of pthread_testcancel() and use
88          it if so (previously it was only used if explicitly enabled by configure
89          option).
90        - Thread class: raise compiler warning if pthread_testcancel() is not
91          available, because it can lead to deadlocks.
92        - Mutex class: Implemented optional bug detection and deadlock debugging
93          features.
94        - Ref<> class is now thread safe (as lock-free and wait-free
95          implementation).
96        - Fixed compilation error with Bison >= 3.6.0.
97        - Fixed rare crash when switching between instruments that had instrument
98          scripts loaded.
99        - Allow EffectChain::InsertEffect() as alternative to
100          EffectChain::AppendEffect() (i.e. with index equal to current chain size).
101        - ConstCapacityArray class: Fixed bug in remove() method.
102        - Fixed crash on certain MIDI RPN and NRPN messages that occurred if no
103          real-time instrument script was loaded.
104    
105      * Real-time instrument scripts:
106        - Added method ScriptVM::setExitResultEnabled() which allows to
107          explicitly enable the built-in exit() function to optionally accept
108          one function argument; the value of the passed exit() function
109          argument will then become available by calling
110          VMExecContext::exitResult() after script execution.
111        - 64 bit support for NKSP integer scripts variables (declare $foo).
112        - Variable names, function names and preprocessor condition names must start
113          with a regular character (a-z or A-Z); starting them with a digit or
114          underscore is not allowed.
115        - NKSP parser fix: equal comparison operator "=" and not equal comparison
116          operator "#" must only accept integer operands.
117        - NKSP language: Implemented support for standard units like Hertz, seconds,
118          Bel including support for metric unit prefixes; so one can now e.g.
119          conveniently use numbers in scripts like "5us" meaning "5 microseconds",
120          or e.g. "12kHz" meaning "12 kilo Hertz", or e.g. "-14mdB" meaning
121          "minus 14 Millidecibel", or e.g. "28c" meaning "28 cents" (for tuning).
122        - NKSP language: Introduced "final" operator "!" which is specifically
123          intended for synthesis parameter values to denote that the synthesis
124          parameter value is intended to be the "final" value for that synthesis
125          parameter that should explicitly be used by the engine and thus causing
126          the sampler engine to ignore all other modulation sources for the same
127          synthesis parameter (like e.g. LFO, EG); by simply prefixing a value,
128          variable or formula with this new "!" operator the expression is marked as
129          being "final".
130        - NKSP script editor API: Added support for detecting standard unit tokens
131          and their potential metric prefix token.
132        - NKSP language: Added support for NKSP real number literals and
133          arithmetic operations on them (e.g. "(3.9 + 2.9) / 12.3 - 42.0").
134        - NKSP language: Added support for NKSP real number (floating point) script
135          variables (declare ~foo).
136        - NKSP language: Added support for NKSP real number (floating point) array
137          script variables (declare ?foo[]).
138        - Built-in script function "message()" accepts now real number argument as
139          well.
140        - Added built-in script function "real_to_int()" and its short hand form
141          "int()" for casting from real number to integer in NKSP scripts.
142        - Added built-in script function "int_to_real()" and its short hand form
143          "real()" for casting from integer to real number in NKSP scripts.
144        - Allow built-in exit() function to potentially accept real number type
145          argument as well.
146        - Built-in script functions may have a different return type depending on
147          the arguments passed to the function.
148        - Built-in script function "abs()" optionally accepts and returns real
149          number.
150        - Built-in script functions "min()" and "max()" optionally accept real
151          number arguments and return real number as result in that case.
152        - NKSP VM API: Allow units and 'final'ness to be returned as result from
153          built-in functions (added methods VMFunction::returnUnitType() and
154          VMFunction::returnsFinal() for that purpose which must be implemented by
155          built-in function implementations).
156        - NKSP language: Allow metric unit prefixes of numeric scalar and array
157          variables to be changed freely at runtime (unlike unit types like Hz etc.
158          which are still sticky, parse-time features of variables which cannot be
159          changed at runtime for the intentional sake of determinism).
160        - NKSP language: 'final' values are prohibited for array variables for now
161          (attempt causes a parsers error).
162        - NKSP language: expressions with unit types (e.g. Hz) are prohibited for
163          conditions of runtime control structures like if(), while(), select()
164          (attempt causes a parser error).
165        - NKSP VM API: Allow built-in functions to perform their own, individual
166          parse time checks of arguments going to be passed to the function at
167          runtime (added method VMFunction::checkArgs() for that purpose).
168        - NKSP language: raise parser warning if only one operand of binary
169          operators (like logical 'or' comparison) contain a 'final' value (because
170          it would always yield in a 'final' result in such cases).
171        - NKSP language: Allow comparison (=, #, <, >, <=, >=) of values with
172          different metric unit prefixes, which will behave as expected (e.g.
173          result of expression '1000us < 2ms' is true).
174        - NKSP language: Allow adding values with different metric unit prefixes
175          (e.g. result of expression '100Hz + 5kHz' is '5100Hz').
176        - NKSP language: Allow subtracting values with different metric unit
177          prefixes (e.g. result of expression '1ms - 20us' is '980us').
178        - NKSP language: Allow multiplying with any metric unit prefixes
179          (e.g. result of expression '2k * 3ms' is '6s'), however multiplications
180          with unit types on both sides (e.g. '2s * 2s') is still prohibited since
181          we don't have any considerable practical use for a term like '4s^2'
182          (hence any attempt multiplying two unit types still causes parser error).
183        - NKSP language: Allow dividing by any metric unit prefixes and allow
184          division of same unit type on both sides (e.g. expression '8kHz / 1000Hz'
185          yields in unit free result '8'). So this is now a way to cast units away
186          e.g. for passing the result to other expressions, certain function calls
187          or variables which are not accepting any units (or that specific unit).
188        - NKSP language: integer arrays and real number arrays can now be converted
189          to strings (e.g. for dumping their content with message() calls for
190          script debugging purposes).
191        - NKSP language: expressions and variables with units are now correctly
192          casted to strings (e.g. with message() calls).
193        - NKSP language: comparing real numbers for equalness (e.g. '~foo = 3.1') or
194          unequalness (e.g. '~foo # 3.1') is now less strict and takes the expected
195          floating point tolerances into account.
196        - NKSP VM API: Added methods VMScalarNumberExpr::evalCastInt() and
197          VMScalarNumberExpr::evalCastReal().
198        - NKSP VM API: Added base class 'VMNumberArrayExpr' for classes
199          'VMIntArrayExpr' and 'VMRealArrayExpr'.
200        - NKSP VM API: replaced all unitPrefix() (parse time) methods by
201          unitFactor() (runtime) methods.
202        - Built-in function "exit()" supports now returning units and 'final'ness
203          for test cases.
204        - The following built-in functions support now units as well: "abs()",
205          "random()", "inc()", "dec()", "in_range()", "min()", "max()",
206          "real_to_int()", "int()", "int_to_real()" and "real()".
207        - Built-in functions "array_equal()", "search()" and "sort()" support now
208          real number arrays (correctly) as well.
209        - Added individual parse time checks of arguments to be passed to built-in
210          functions "random()", "inc()", "dec()", "in_range()", "min()", "max()",
211          "array_equal()" and "search()" specific for their individual purposes.
212        - NKSP VM refactoring: Renamed all methods, functions and classes matching
213          pattern *ScalarNumber* to simply *Number* (that is i.e. classes
214          VMScalarNumberExpr -> VMNumberExpr, ScalarNumberExpr -> NumberExpr,
215          ScalarNumberVariable -> NumberVariable, ScalarNumberBinaryOp ->
216          NumberBinaryOp, VMScalarNumberResultFunction -> VMNumberResultFunction,
217          method VMExpr::asScalarNumberExpr() -> VMExpr::asNumber(), function
218          isScalarNumber() -> isNumber()).
219        - NKSP VM API: Added 4 overridden methods to class VMNumberExpr:
220          evalCastInt(MetricPrefix_t), evalCastInt(MetricPrefix_t,MetricPrefix_t),
221          evalCastReal(MetricPrefix_t), evalCastReal(MetricPrefix_t,MetricPrefix_t)
222          as convenient methods for automatically converting values to expected
223          metric value basis.
224        - Built-in function "wait()" accepts now both integers and real numbers as
225          argument.
226        - NKSP VM API cleanup: Get rid of legacy method
227          VMFunction::argType(vmint iArg) which was already superseded by its new
228          replacement VMFunction::acceptsArgType(vmint iArg, ExprType_t type).
229        - NKSP parser: if wrong argument type was passed to a built-in function and
230          that built-in function accepts more than one data type for the argument,
231          then show all supported data types as parser error message.
232        - Built-in function "play_note()" accepts now real numbers and seconds as
233          unit type as well for its 3rd and 4th function arguments.
234        - The following built-in functions accept now real numbers as well for their
235          2nd function argument: "change_vol()", "change_tune()", "change_cutoff()",
236          "change_attack()", "change_decay()", "change_release()",
237          "change_sustain()", "change_cutoff_attack()", "change_cutoff_decay()",
238          "change_cutoff_sustain()", "change_cutoff_release()",
239          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
240          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
241          "change_pan_time()", "fade_in()", "fade_out()", "change_play_pos()".
242        - Fixed built-in function "change_play_pos()" not having accepted metric
243          prefixes at all.
244        - Fixed the following built-in functions having misinterpreted values given
245          with unit type (for their 2nd argument) as if they were relative values
246          (that is as if they were passed without a unit type): "change_attack()",
247          "change_decay()", "change_release()", "change_cutoff_attack()",
248          "change_cutoff_decay()", "change_cutoff_release()".
249        - Fixed the following built-in functions having applied completely wrong
250          'final' values: "change_sustain()", "change_cutoff_sustain()" (since the
251          respective EGs being their modulation sink assume uint data type with
252          value range 0..1000 instead of 0.0..1.0.
253        - Added individual parse-time checks of function arguments for the following
254          built-in functions: "play_note()", "note_off()", "set_event_mark()",
255          "delete_event_mark()", "by_marks()", "change_cutoff()", "change_attack()",
256          "change_decay()", "change_release()", "change_cutoff_attack()",
257          "change_cutoff_decay()", "change_cutoff_release()",
258          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
259          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()" and
260          "change_pan_time()".
261        - Don't abort function call if unit type was used and at the same time
262          'final' operator was omitted for the primary value argument of the
263          following built-in functions: "change_cutoff()", "change_attack()",
264          "change_decay()", "change_release()", "change_cutoff_attack()",
265          "change_cutoff_decay()", "change_cutoff_release()",
266          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
267          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
268          "change_pan_time()", instead imply 'final'ness at runtime and raise an
269          appropriate parser warning at parse time.
270        - Added built-in real number functions "round()", "ceil()", "floor()",
271          "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()", "sin()",
272          "cos()", "tan()", "asin()", "acos()", "atan()".
273        - Added built-in script real number constant "~NI_MATH_PI".
274        - Added built-in script real number constant "~NI_MATH_E".
275        - NKSP language: Allow unary '+' operator.
276        - Added built-in script functions "msb()" and "lsb()".
277        - NKSP language: Added support for RPN event handler
278          ("on rpn ... end on" in instrument scripts).
279        - NKSP language: Added support for NRPN event handler
280          ("on nrpn ... end on" in instrument scripts).
281        - Added built-in read-only variables "$RPN_ADDRESS" and "$RPN_VALUE" which
282          may be read from the new RPN/NRPN script handlers to get the (N)RPN
283          parameter that had been changed and its new value.
284        - Added built-in const variables "$NI_CB_TYPE_RPN" and "$NI_CB_TYPE_NRPN"
285          which are identifying the new (N)RPN handlers as such at script runtime.
286        - Implemented built-in script function "set_rpn()".
287        - Implemented built-in script function "set_nrpn()".
288        - Fix: built-in functions returning an array type were broken and caused a
289          crash when the built-in function's (supposed to be array) result value was
290          used by the script VM.
291        - Removed upper value constraint for 2nd argument of built-in functions
292          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
293          "change_pitch_lfo_freq()","change_reso()", "change_cutoff()",
294          "change_amp_lfo_depth()", "change_cutoff_lfo_depth()" and
295          "change_pitch_lfo_depth()", to allow e.g. passing value 2000000 to double
296          the LFO frequency / resonance / cutoff frequency.
297        - Reduced code involved for parsing NKSP variable declarations by using 2
298          generalized grammar rules with optional components (i.e. optional value
299          assignment and optional variable qualifiers) instead of previous linear
300          combinations of grammar rules, which also fixes some edge case.
301        - NKSP language parser: track code block locations also by a) raw byte
302          position in NKSP source code string and b) length of that code block in
303          bytes (along to the already existing code block tracking by line/column);
304          and added appropriate new members to public C++ API classes like
305          'firstByte' and 'lengthBytes' to class VMSourceToken and struct CodeBlock.
306        - NKSP language: Added support for 'patch' variable qualifier (capture their
307          locations and allow replacement of their assignment expression via VM C++
308          API).
309        - Fixed incorrect EG times if standard measuring unit was passed to built-in
310          functions "change_attack()", "change_decay()" or "change_release()".
311        - Fixed intermediate function result values never having reflected any
312          standard measuring unit type.
313        - Fixed re-entrant issue with function calls which caused wrong result
314          values if the same function was called multiple times in a term
315          (specifically if metric prefixes were used).
316        - NKSP language: Just throw a warning, not an error if an array variable of
317          size zero was declared.
318        - NKSP language: Allow omitting explicit array size on array variable
319          declaration if combined with immediate value assignment
320          (e.g. declare %foo[] := ( 1, 2, 3 ) ).
321        - NKSP language: emit warning if an array variable was declared with bigger
322          array size than amount of initial values been assigned, and initialize the
323          missing array elements with zero in this case.
324        - Fixed built-in NKSP exit() function to behave as return statement.
325        - NKSP parser: Fixed crash if unary '-' operator was used on a non-number
326          data type.
327        - NKSP VM: Fixed the "release" handler being executed too often under
328          certain situations if polyphonic data was passed from "note" handler to
329          "release" handler.
330        - Fixed memory leak in NKSP parser: string tokens were allocated as C
331          strings and never freed.
332        - Fixed incorrect polyphonic data transfer from wrong note handler to
333          release handler; which also fixes no release handler being executed
334          sometimes, and due to the latter it also fixes potential crashes as some
335          polyphonic script events were never released and the engine hence was
336          running out of free script events.
337        - Fixed crash when handling array results of built-in functions
338          (e.g. "num_elements(by_marks($MARK_1)").
339        - NKSP VM: Fixed dead note events not been removed from user's event groups
340          (i.e. causing incorrect behaviour of built-in NKSP functions by_marks()
341          and set_event_mark() after max. size of event group list was exhausted).
342    
343      * test cases:
344        - Fixed compiler errors in test cases.
345        - Updated README for how to compile & run test cases.
346        - Updated test case
347          MutexTest::testDoubleLockStillBlocksConcurrentThread() to latest
348          expected behaviour of the Mutex class implementation (recursive
349          mutex type).
350        - Added test cases for NKSP core language aspects and core built-in
351          functions.
352        - Fixed thread tests segfaulting on Linux.
353        - NKSP: Added real number test cases for built-in functions exit(),
354          int_to_real(), real(), real_to_int() and int(), as well as for the
355          plus, minus and negate language operators.
356        - Added massive amount of NKSP test cases for standard measuring units and
357          'final' operator usage cases.
358        - Added NKSP test cases for (floating point tolerance aware) real number
359          equalness / unequalness comparison.
360        - Added NKSP int array and real array tests for value assignment and
361          initialization of arrays.
362        - Added NKSP test cases for built-in functions "round()", "ceil()",
363          "floor()", "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()",
364          "sin()", "cos()", "tan()", "asin()", "acos()", "atan()".
365        - Added NKSP test cases for unary '+' operator.
366        - Added NKSP test cases for core built-in variables.
367        - Added thorough NKSP test cases for variable declarations.
368    
369      * GigaStudio/Gigasampler format engine:
370        - LFOTriangleIntMath and LFOTriangleIntAbsMath: Fixed FlipPhase=true
371          behaviour for start_level_mid.
372        - Changed LFO start levels: LFO1 and LFO2 both to mid, LFO3 to max. start
373          level (see discussion "GigaStudio LFO compatibility" on mailing list
374          from 2019-09-26 for details).
375        - Changed default wave form for all 3 LFOs to sine (instead of triangle;
376          see discussion "GigaStudio LFO compatibility" on mailing list from
377          2019-09-26 for details).
378        - Format extension: Added support for different LFO wave forms (currently
379          either sine [default], triangle, saw or square).
380        - Format extension: Added support for LFO phase displacement (0°..360°).
381        - Format extension: Added support for flipping LFO polarity on LFO 3
382          (in the original gig format this was only available for LFO 1 and LFO 2).
383        - Format extension: Support for additional filter types:
384          lowpass 1/2/4/6-pole, highpass 1/2/4/6-pole, bandpass 2-pole,
385          bandreject 2-pole.
386        - Fixd potential crash with polynomial interpolator and max. pitch.
387        - If minimum cutoff is defined, remap cutoff controller CC values to really
388          span the entire possible cutoff range (and avoiding a dead controller
389          zone).
390        - Implemented support for loading instrument scripts with 'patch' variables
391          (by patching these script variables with potentially overridden ones by
392          gig Instrument).
393    
394      * SFZ format engine:
395        - Fixed support for regions with loccN/hiccN conditions on more than one
396          MIDI controller.
397        - Fixed internal opcode 'xfin_hivel' falsely being set by user opcode
398          'xfin_lovel' (patch by Christian Czezatke).
399    
400      * Benchmarks:
401        - Fixed benchmarks/triang.cpp falsely having favoured "int math abs"
402          algorithm (since result of 2nd run was not accumulated).
403        - Added benchmark for saw wave (benchmarks/saw.cpp).
404        - Added benchmark for sine wave (benchmarks/sine.cpp).
405        - Added benchmark for square wave (benchmarks/square.cpp).
406        - Increased amount of benchmarks runs by factor 6 to achieve benchmark times
407          which are large enough on modern systems.
408    
409    Version 2.1.1 (27 Jul 2019)
410    
411      * Real-time instrument scripts:
412        - Fixed behavior of built-in NKSP functions change_sustain(),
413          change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain()
414          and change_cutoff_release().
415    
416      * general changes:
417        - Only play release trigger samples on sustain pedal up if this behaviour
418          was explicitly requested by the instrument (otherwise only on note-off).
419        - Fixed compiler warnings.
420        - Fixed compilation error when cross-compiling to Mac.
421        - FX Sends: Provide more useful error messages on routing problems
422          (see bug #169).
423        - LSCP doc: Be more clear describing the two distinct approaches
424          of using external vs. internal effects (see bug #169).
425        - "optional" class: Fixed comparison operators.
426    
427      * Gigasampler/GigaStudio format engine:
428        - Format extension: If requested by instrument then don't play release
429          trigger sample on note-off events.
430    
431      * SFZ format engine:
432        - Fixed memory leak when releasing samples
433          (fixes bug #307, patch by Jacek Roszkowski)
434        - Fixed potential crash when a sample is shared by more than one region
435          (fixes bug #308, patch by Jacek Roszkowski).
436        - Opcode 'sample': Added support for built-in sample '*silence'
437          (fixes bug #310, patch by Jacek Roszkowski).
438    
439    Version 2.1.0 (25 Nov 2017)
440    
441      * SFZ format engine:
442        - added support for <global>, <master> and #define (patch by Alby M)
443        - Removed code duplication in SFZ file loading code.
444        - Added support for sfz extension opcode 'script' which may be used to
445          load real-time instrument script file (NKSP script language).
446        - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
447        - Fixed unintended volume fade-in of voices under certain conditions.
448        - sfz parser: allow missing space between header and opcode
449    
450      * Gigasampler/GigaStudio format engine:
451        - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
452          cutoff settings.
453        - Got rid of resembling an ancient GSt misbehavior which did not pitch at
454          all if an up-pitch of more than 40 semi tones was requested (I don't
455          think there is any stock gig sound that requires this behavior to
456          resemble its original sound).
457        - Added support for controlling whether the individual EGADSR stages may
458          be aborted (as LinuxSampler extension to the original GigaStudio 4
459          format).
460    
461      * general changes:
462        - fixed printf type errors (mostly in debug messages)
463        - use unique_ptr instead of auto_ptr when building with C++11
464        - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
465          allowing to sort data efficiently in real-time safe manner.
466        - RTList class: added methods for moving/inserting elements to arbitrary
467          position within a list.
468        - RTList class: added method fromPtr() for creating an Iterator object from
469          a raw element pointer.
470        - Attempt to partly fix resetting engine channels vs. resetting engine, an
471          overall cleanup of the Reset*(), ConnectAudioDevice(),
472          DisconnectAudioDevice() API methods would still be desirable though,
473          because the current situation is still inconsistent and error prone.
474        - Active voices are now internally grouped to "Note" objects, instead of
475          being directly assigned to a keyboard key. This allows more fine graded
476          processing of voices, which is i.e. required for certain instrument
477          script features.
478        - Fix: Release trigger voices were not spawned on sustain pedal up
479          (CC #64) events.
480        - Fix: Release trigger voices can now also distinguish correctly between
481          note-off and sustain pedal up events.
482        - All engines: Increased ramp speed of volume smoother and pan smoother
483          (while slow rate of crossfade smoother is preserved) to allow quick
484          volume and pan changes by instrument scripts for instance.
485        - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
486          properly and thus were ignored for certain uses.
487        - Added new C++ API method
488          VirtualMidiDevice::SendChannelPressureToSampler().
489        - windows, 32-bit: fixed potential crashes by making sure the stack in
490          sub threads is 16-byte aligned
491        - fixed numerous compiler warnings
492        - Fixed invalid (note-on) event ID being assigned to new Note objects.
493        - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
494          fixes potential undefined behavior.
495        - Fixed Note object leak when triggering notes on keys which did not
496          have a valid sample mapped (fixes bug #252).
497        - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
498        - linuxsampler binary fix: option --create-instruments-db ignored
499          subsequent optional argument due to glibc's implementation oddity
500          which expects a "=" sign, but no space between them.
501    
502      * packaging changes:
503        - removed unnecessary dependency to libuuid
504          (originated by libgig's usage of it)
505        - Automake: set environment variable GCC_COLORS=auto to allow GCC to
506          auto detect whether it (sh/c)ould output its messages in color.
507        - Debian: Fixed packaging error about invalid "Source-Version"
508          substitution variable.
509        - Debian: Raised Debian compatibility level to Debian 9 "Stretch".
510        - Debian: Added build dependency to libsqlite3-dev for building
511          linuxsampler with instruments DB support.
512    
513      * Real-time instrument scripts:
514        - Implemented scheduler for delayed MIDI events and for suspended scripts.
515        - Built-in script function "wait()": implemented support for function's
516          "duration-us" argument, thus scripts using this function are now
517          correctly resumed after the requested amount of microseconds.
518        - Built-in script function "play_note()": implemented support for
519          function's "duration-us" argument, thus notes triggered with this
520          argument are now correctly released after the requested amount of
521          microseconds.
522        - Fix: script events were not cleared when engine channel was reset,
523          potentially causing undefined behavior.
524        - Fixed crash which happened when trying to reference an undeclared
525          variable.
526        - Built-in script function "play_note()": Added support for passing
527          special value -1 for "duration-us" argument, which will cause the
528          triggered note to be released once the original note was released.
529        - Instrument script classes now exported with the liblinuxsampler C++ API.
530        - Added new API method ScriptVM::syntaxHighlighting() which provides
531          a convenient syntax highlighting backend for external instrument
532          script editor applications.
533        - Added new C++ API class "ScriptVMFactory".
534        - Extended parser issues to provide not only first line and first
535          column, but also last line and last column of issue (thus marking
536          the precise span of the issue within the source code).
537        - Reload script automatically after being modified by an instrument
538          editor.
539        - NKSP language grammar correction: allow empty event handler bodies
540          like "on note end on".
541        - Implemented built-in script function "change_vol()".
542        - Implemented built-in script function "change_tune()".
543        - Implemented built-in script function "change_pan()".
544        - Implemented built-in script function "change_cutoff()".
545        - Implemented built-in script function "change_reso()".
546        - Implemented built-in script function "event_status()".
547        - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
548          "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
549          "event_status()" function.
550        - NKSP language: Added support for bitwise operators ".or.", ".and."
551          and ".not.".
552        - NKSP language scanner: Fixed IDs matching to require at least one
553          character (i.e. when matching function names or variable names).
554        - NKSP language scanner: disabled unusued rules.
555        - Fixed behavior of play_note() and note_off() functions which must
556          be distinguished engine internally from "real" MIDI note on/off
557          events in order to avoid misbehaviors like hanging notes.
558        - Implemented built-in script variable "$KSP_TIMER".
559        - Implemented built-in script variable "$NKSP_REAL_TIMER".
560        - Implemented built-in script variable "$NKSP_PERF_TIMER".
561        - Implemented built-in script variable "$ENGINE_UPTIME".
562        - Implemented built-in script function "inc()".
563        - Implemented built-in script function "dec()".
564        - NKSP language fix: division expressions were evaluated too often.
565        - NKSP language fix: string concatenation operator was right
566          associative instead of left (to right).
567        - NKSP language correction: allow empty statements in entire language
568          (i.e. "if end if").
569        - Implemented built-in script function "stop_wait()".
570        - Implemented built-in script variable "$NI_CALLBACK_ID".
571        - Implemented built-in script variable "$NI_CALLBACK_TYPE".
572        - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
573        - Added support for read-only built-in variables (respectively
574          handled by the script parser).
575        - Added built-in script constant "$NI_CB_TYPE_INIT".
576        - Added built-in script constant "$NI_CB_TYPE_NOTE".
577        - Added built-in script constant "$NI_CB_TYPE_RELEASE".
578        - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".

580        - Implemented built-in script function "change_attack()".
581        - Implemented built-in script function "change_decay()".
582        - Implemented built-in script function "change_release()".
583        - Fixed all change_*() built-in script functions to apply their
584          synthesis parameter changes immediately in case the respective note
585          was triggered at the same time, instead of scheduling the parameter
586          change, especially because it would cause some parameter types's
587          changes either to be ramped (i.e. change_vol()) or other types even
588          to have not effect at all (i.e. change_attack()).
589        - Implemented built-in script function "sh_left()".
590        - Implemented built-in script function "sh_right()".
591        - Implemented built-in script function "min()".
592        - Implemented built-in script function "max()".
593        - NKSP Fix: "init" event handler was not always executed when a script
594          was loaded.
595        - NKSP built-in wait() script function: abort script execution if
596          a negative or zero wait time was passed as argument (since this is
597          a common indication of a bug either of the script or even of the
598          engine, which could lead to RT instability or even worse).
599        - ScriptVM: Implemented automatic suspension of RT safety
600          threatening scripts.
601        - Provide more user friendly error messages on syntax errors.
602        - Fixed NKSP parser warning "Not a statement" when assigning an
603          initializer list to an array variable.
604        - Implemented built-in script array variable "%ALL_EVENTS".
605        - Implemented built-in script function "in_range()".
606        - Implemented built-in script function "change_amp_lfo_depth()".
607        - Implemented built-in script function "change_amp_lfo_freq()".
608        - Implemented built-in script function "change_pitch_lfo_depth()".
609        - Implemented built-in script function "change_pitch_lfo_freq()".
610        - Implemented built-in script function "change_vol_time()".
611        - Implemented built-in script function "change_tune_time()".
612        - Implemented built-in script function "fade_in()".
613        - Implemented built-in script function "fade_out()".
614        - Fixed acceptance of wrong data type of parameters passed to built-in
615          script functions "change_vol()", "change_tune()", "change_pan()",
616          "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
617          "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
618          "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
619        - Added built-in script function "get_event_par()" and implemented some
620          of its possible parameter selections.
621        - Added built-in script function "set_event_par()" and implemented some
622          of its possible parameter selections.
623        - Fixed a bunch of scheduler time related bugs.
624        - Fixed polyphonic variables not being reset to zero after usage.
625        - Built-in "ignore_event()" function: argument is now optional, like with
626          built-in function "ignore_controller()".
627        - Implemented built-in script function "change_velo()".
628        - Implemented built-in script function "change_note()".
629        - Adjusted behavior of "change_vol()" and "change_tune()" to a more
630          intuitive behavior if used in combination with "change_vol_time()" or
631          "change_tune_time()" respectively: now tuning/volume changes are only
632          assigned (without delay) immediately to a new note if the respective
633          timing function has not been called before, otherwise the volume/tuning
634          changes are automatically faded (before, only the event's time stamp was
635          relevant).
636         - Implemented built-in script function "array_equal()".
637         - Implemented built-in script function "search()".
638         - Implemented built-in script function "sort()".
639         - NKSP Fix: Never suspend "init" event handlers.
640         - Implemented built-in script function "same_region()" (currently only
641           available for gig format engine).
642         - Added built-in script constant "$NKSP_LINEAR".
643         - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
644         - Implemented built-in script function "change_vol_curve()".
645         - Implemented built-in script function "change_tune_curve()".
646         - built-in "play_note()" function now supports a sample playback start
647           offset with argument 3, where special value -1 means to use the regular
648           sample offset as defined by the instrument file.
649         - Built-in array variable %KEY_DOWN[] is now a read-only variable.
650         - Built-in variable $EVENT_NOTE is now a read-only variable.
651         - Built-in variable $EVENT_VELOCITY is now a read-only variable.
652         - built-in "play_note()" function now accepts -2 for its fourth argument
653           (note duration) which means the life time of the note shall be sticked
654           to the requested note number of argument 1.
655         - Fix: built-in "play_note()" function now returns 0 as result value if
656           -1 was passed for its fourth argument (note duration) and the respective
657           parent note is already gone.
658        - Implemented built-in script function "change_play_pos()".
659        - NKSP language: Added support for user declared const array variables.
660        - NKSP language: Raise parser warning if array variable is accessed with
661          an index that exceeds the array's size.
662        - NKSP language fix: Unknown characters were not handled correctly.
663        - NKSP language: Added support for "synchronized .. end synchronized"
664          code blocks.
665        - Implemented built-in script function "abort()" which allows to abort
666          another script handler by passing its callback ID.
667        - Fixed potential memory access bug and potential undefined behavior of
668          "init" event handlers.
669        - Print a time stamp along to each call of built-in function "message()".
670        - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
671          to retrieve all code blocks filtered out by the preprocessor.
672        - Added built-in script function "fork()".
673        - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
674        - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
675        - Fixed potential crash when accessing dynamic built-in array variables.
676        - Added built-in script function "callback_status()".
677        - Added built-in constant $CALLBACK_STATUS_TERMINATED.
678        - Added built-in constant $CALLBACK_STATUS_QUEUE.
679        - Added built-in constant $CALLBACK_STATUS_RUNNING.
680        - Removed max. value limitation of built-in functions "change_attack()",
681          "change_decay()" and "change_release()" to i.e. allow passing 2000000
682          for doubling the respective time.
683        - NKSP script editor syntax highlighting API: Fixed app termination due
684          to a lexer start condition stack underrun.
685        - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
686          USE_CODE_IF_NOT() preprocessor statements.
687        - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
688          can be set to disable all subsequent built-in "message()" function calls
689          on preprocessor level.
690        - Implemented built-in script function "change_sustain()".
691        - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
692          to avoid the editor app to crash on ill-formed text input.
693        - Added built-in script function "change_pan_time()".
694        - Added built-in script function "change_pan_curve()".
695        - Added built-in script function "change_cutoff_attack()".
696        - Added built-in script function "change_cutoff_decay()".

720        - removed empty directories left from the cvs to svn migration
721        - fixed compilation with gcc 4.6.1
722        - another "make dist" fix, for the LV2 plugin
723        - made --enable-pthread-testcancel default on Mac OS X
724        - minor Makefile fix for building lscpparser when build and source

747        - support building with spaces in vst sdk path
748        - enabled automake 'subdir-objects' option and moved external
749          source references (vst, au, asio) from makefiles to cpp files,
750          in order to get rid of warnings from automake 1.14
751    
752      * general changes:
753        - Refactoring: moved the independent code from
754          the Gigasampler format engine to base classes
755        - command line option '--profile' is currently disabled, since the
756          respective profiling code is currently broken
757        - Introduced support for optional environment variable
758          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
759          where the sampler shall look for instrument editor plugins
760          (patch by Luis Garrido, slightly modified).
761        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
762        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
763        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
764          note (in this implementation of the sampler its simply hard routed to
765          the 1st effect send of the sampler channel, no matter what the actual
766          effect type is)
767        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
768          note (in this implementation of the sampler its simply hard routed to
769          the 2nd effect send of the sampler channel, no matter what the actual
770          effect type is)
771        - implemented support for internal LADSPA effects
772        - raised limit of program change queue from 100 to 512
773          (as suggested by Alex Stone)
774        - implemented sine LFO, pulse LFO and saw LFO
775        - experimental support for per voice equalization
776        - added command line option --exec-after-init
777        - Introduced new C++ API method:
778          EngineChannel::InstrumentFileName(int index)
779          allowing to retrieve the whole list of files used for the loaded
780          instrument on an engine channel (a.k.a. part). Some GigaStudio
781          instruments for example are splitted over several files like
782          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
783        - Added new C++ API method Sampler::GetGlobalMaxVoices().
784        - Added new C++ API method Sampler::GetGlobalMaxStreams().
785        - Added new C++ API method Sampler::SetGlobalMaxVoices().
786        - Added new C++ API method Sampler::SetGlobalMaxStreams().
787        - Various "const" and "restrict" optimizations.
788        - all engines: add pan CC value to instrument pan parameter before
789          applying panning, instead of using two separate pan functions in
790          series (#182)
791        - added a lock guard class for exception safe mutex handling and
792          used it everywhere appropriate
793        - Immediately apply scale tuning changes to active voices.
794        - Exposed scale tuning to C++ API (along to the already existing standard
795          SysEx way).
796        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
797          and broken for ppc64. (Seq_cst loads and stores are actually not
798          used in LS, so the bug wasn't noticable.)
799        - lsatomic.h: added ARMv7 support
800        - Added support for multiple MIDI input ports per sampler channel (and
801          added various new C++ methods for this new feature / design change, old
802          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
803          as deprecated but are still there and should provide full behavior
804          backward compatibility).
805        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
806          unsafe and caused compilation error with clang 2.x).
807        - Bugfix: only process the latest MIDI program change event.
808        - Introducing the LSCP shell, which provides convenient control of the
809          sampler from the command line by providing LSCP aware features.
810        - VirtualMidiDevice: Added support for program change.
811        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
812        - VirtualMidiDevice: Added support for pitch bend.
813        - Aftertouch: extended API to explicitly handle channel pressure and
814          polyphonic key pressure events (so far polyphonic pressure was not
815          supported at all, and channel pressure was rerouted as CC128 but not
816          used so far).
817        - Added initial support for real-time instrument scripts. The script VM
818          code is shared by all sampler engine implemementations, however only the
819          gig file format currently provides support for storing instrument scripts
820          (as LinuxSampler extension to the original GigaStudio 4 format).
821    
822      * Gigasampler format engine:
823        - implemented the "round robin keyboard" dimension
824        - fixed round robin and random dimensions for cases when number of
825          dimension zones is not a power of two
826        - made round robin use a counter for each region instead of each
827          key
828        - bugfix: pitch LFO controller "internal+aftertouch" was broken
829        - bugfix: filter keyboard tracking was broken
830        - filter performance fix (an unnecessary copy was made of the
831          filter parameters in each sub fragment)
832        - handle special case when pan parameter in gig file has max or
833          min value
834        - Exclusive Groups: don't ever stop voices of the same note,
835          doesn't sound naturally with a drumkit
836        - fixed EG1 modulation when attack or release is zero
837        - Fixed support for 'aftertouch' attenuation controller.
838        - Fixed crash that happened with velocity split sounds under certain
839          conditions (see also previous commit on libgig).

860        - fine-tuned the default velocity curve
861        - added support for transpose
862        - fixed crash when using sw_down/up
863        - improved logic for sw_lokey/hikey/up/down/last
864        - added more v1 aliases to parser
865        - reduced memory usage for sfz data
866        - RT-safeness: avoid malloc in audio thread

875        - use loop markers from sample file if loop_start and loop_end are
876          not set in sfz file
877        - implemeted filters. Filter types: lowpass, bandpass, bandreject

1020          changing sample rate or block size, the number of channels was
1021          incorrectly set to two. This caused silence in Cubase 5.
1022        - save engine type (gig, sfz or sf2) in plugin state

1032          the plugin was loaded a second time (#174)
1033        - plugin bugfix: instrument loading hang when the plugin was
1034          loaded a second time (this time it's for Linux and Mac, previous
1035          similar fix was for Windows)
1036        - thread safety fixes for the instrument loading thread
1037        - LV2: use the new lv2 package if present
1038        - VST: try to open Fantasia automatically on Linux and Mac too (on
1039          Linux, the Fantasia jar should be placed in <prefix>/share/java)
1040        - VST: fixed crashes on Linux Ardour and EnergyXT
1041        - DSSI bugfix: it wasn't possible to change engine type. The MIDI
1042          port and audio channel routing for DSSI plugins are now visible.
1043        - LV2: use urid and atom extensions instead of deprecated uri-map
1044          and event

1051          sampler's internal MIDI instrument mapping system
1052    
1053      * Instrument editor interface:
1054        - Changed instrument editor plugin interface, providing additional
1055          informations like the EngineChannel for which the instrument editor was
1056          spawned for. This allows the instrument editors to interact more actively
1057          with the sampler.
1058    
1059      * MIDI driver:
1060        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
1061          the ALSA sequencer client name

1065        - MME: removed compiler warning
1066        - CoreMIDI: implemented driver specific port parameter "CORE_MIDI_BINDINGS",
1067          which allows to retrieve the list of CoreMIDI clients / ports and to connect
1068          to them a la JACK, via the usual sampler APIs
1069        - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
1070          the driver will automatically connect to other CoreMIDI clients' ports
1071          (e.g. external MIDI devices being attached to the Mac)
1072        - added support for MIDI note on velocity filter
1073        - CoreMIDI: fixed memory deallocation error
1074        - Fixed variable underflow in VirtualMidiDevice, which caused graphical
1075          virtual keyboards in frontends / instrument editors being stuck.
1076        - Bugfix in VirtualMidiDevice: process note on with velocity 0 as note off.
1077        - Implemented missing handling of MIDI "running status".
1078        - CoreMIDI fix: a MIDIPacket can contain more than one event per packet.
1079        - MME bugfix: driver wasn't closed properly
1080        - CoreMIDI: automatically connect to all input sources by default (driver
1081          parameter "AUTO_BIND").
1082        - CoreMIDI: fixed auto bind feature to CoreMIDI ports that go online
1083        - CoreMIDI: fixed minor memory leak
1084

1090          RT context.
1091        - ASIO driver: removed compiler warnings
1092        - CoreAudio: fixed minor error handling bug
1093        - ASIO driver: be more verbose when no ASIO card could be found (fixes #203)
1094        - JACK audio: return the JACK server's current sample rate as default value
1095          for audio device parameter "SAMPLERATE" (fixes #166).
1096    
1097      * LSCP server:
1098        - added support for sending MIDI CC messages via LSCP command
1099          "SEND CHANNEL MIDI_DATA CC <sampler-chan> <ctrl> <val>"

1140        - Show currently available auto completion while typing.
1141        - Added support for browsing command history with up / down keys.
1142        - Show all possible next symbols immediately right to the current command
1143          line while typing (no double tab required for this feature, as it would
1144          be the case in other shells).
1145        - Added support for moving cursor left/right with arrow keys.
1146        - Added support for built-in LSCP reference documentation, which will
1147          automatically show the relevant LSCP reference section on screen as soon
1148          as one specific LSCP command was detected while typing on the command

1163          max. four function arguments are currently implemented yet though).
1164        - Implemented built-in script int variable $EVENT_ID.
1165        - Implemented built-in script function "ignore_event()"
1166        - Implemented built-in script function "ignore_controller()" (may have one

1205          channel to a different engine type
1206        - fixed crash when deleting a sampler channel or changing engine
1207          type while an instrument load was in progress
1208        - bugfix: playing a note while changing the instrument could cause
1209          a crash, or give "Handing back unknown region" error messages
1210        - bugfix: calling SET VOICES (which Fantasia does on start and
1211          refresh) could cause instruments to be unloaded
1212        - Mac OS X: fixed name collision of enum in EffectControl and
1213          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
1214        - Mac OS X: fixed hanging threads
1215        - Windows: disabled the previous thread fix on non-Mac systems, as
1216          it caused hanging threads on Windows
1217        - Fixed possible crashes due to corrupted MIDI/audio device list
1218          after MIDI/audio device creation failure
1219        - When creating MIDI instrument map entries with "PERSISTENT" type, the
1220          instruments were uselessly precached with zero samples, however it still
1221          took the full preloading time and on 1st program change the respective
1222          instrument was completely reloaded again.
1223        - fixed handling of rapid bank select and program change messages
1224          sent to the same sampler channel (patch from the Open Octave
1225          project, slightly adjusted)
1226        - fixed crash when trying to create an effect instance with controls
1227          which min and/or max values depend on the sample rate
1228        - fixed bug #162
1229        - bugfix: LADSPA_PATH was not evaluated correctly when containing
1230          multiple paths (#165)
1231        - thread safety fixes for the instrument loading thread
1232        - bugfix: instrument loading crashed for sfz and sf2 in Ardour
1233          (#176)
1234        - more thread safety fixes for the instrument loading thread
1235        - sfz/sf2 engine: fixed crash when using small audio fragment size
1236        - Mac OS X: fixed crash when unloading plugin on 10.7 and later
1237        - Mac OS X: fixed process hang when unloading 32-bit plugin (bug
1238          introduced in previous fix)
1239        - fixed crash when a channel received a program change while
1240          playing a note in a key group
1241        - fixed erroneous error message piping in VoiceBase.h
1242          (labelled "Disk stream not available in time")
1243        - Update effects on sample rate & period size changes (to avoid
1244          crashes and noise on such transitions).
1245        - ignore missing LADSPA paths without ignoring valid LADSPA paths
1246          (fixes #208)
1247        - Fixed bug in LSCP grammar definition which caused a statement like
1248          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1249          practically irrelevant, however it caused problems with the new LSCP
1250          shell's auto completion feature).
1251        - Fixed MIDI program change messages being ignored if quickly executed
1252          after each other (fixes #231).
1253    
1254    Version 1.0.0 (31 July 2009)
1255    
1256      * packaging changes:
1257        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
1258          causing e.g. the libgig test to fail when
1259          "./configure --disable-jack-driver" was used
1260          (patch by Alexis Ballier)
1261        - fixed compilation with gcc 4.3
1262        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
1263        - fixed configure so it detects x86_64 (#107)
1264        - fixes for building with newer MinGW versions

1268        - Windows: look for editor plugins and Fantasia using base
1269          directory of liblinuxsampler dll (look in the same directory and one
1270          directory above)
1271        - configure script fix: removed unconditional use of SSE
1272        - fixed building with sqlite installed in a non-standard directory
1273        - when cross-compiling, don't try to create instruments.db
1274        - fix for new mingw-w64 version, which has usleep
1275    
1276      * general changes:
1277        - bugfix: on some POSIX systems instrument editor plugins refused to
1278          load as we used a non-portable Linux specific struct field
1279          (fixes bug #70, patch by Ronald Baljeu)
1280        - fixed endless loop which occured when loading an instrument editor
1281          plugin DLL on Windows systems failed
1282        - fixed memory leaks that occurred when liblinuxsampler was unloaded
1283        - optimized the SynchronizedConfig class so it doesn't wait
1284          unnecessarily long after an update
1285        - added support for notifying instrument editors on note-on / note-off
1286          events (e.g. to highlight the pressed keys on the virtual keyboard
1287          of gigedit)
1288        - added support for triggering notes by instrument editors (see above)
1289        - be verbose on DLL load errors (on Linux)
1290        - fixed di-harmonic triangle LFO implementation (this LFO implementation
1291          is only used by very few systems, most pick the int math
1292          implementation, which is usually faster)
1293        - fixes for audio drivers with varying buffer sizes
1294        - experimental support for running LinuxSampler as a DSSI, LV2 and
1295          VST plugin
1296        - notification events for stream/voice count statistics are now sent
1297          only when there are actual changes
1298        - added memory ordering constraints to improve stability on
1299          multi-core and multi-cpu systems
1300        - maximum voices and disk streams can now be altered at runtime
1301        - fixed CPU feature detection on x86_64 (maybe fixes #108)
1302        - automatic stacktrace mechanism is now turned off by default and can
1303          be switched on by command line option "--stacktrace" (the automatic
1304          stacktrace mechanism seems to be broken on most systems at the moment)
1305        - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
1306          a pointer to the launched InstrumentEditor object
1307        - added optional 3rd party user data parameter for following
1308          liblinuxsampler C++ API methods: InstrumentEditor::Main(),
1309          InstrumentEditor::Launch(),
1310          InstrumentManager::LaunchInstrumentEditor()
1311        - theoretical fix: made SynchronizedConfig follow C++0x memory
1312          model more strictly
1313        - fixes for using large audio device buffers
1314        - Windows: add the installation directory to the DLL search path
1315          when loading an editor plugin (solves problems with VST and
1316          gigedit on systems with other GTK versions installed)
1317        - updated linuxsampler man page
1318    
1319      * audio driver:
1320        - removed the nonsense audio channel constraint (which was hard coded to
1321          max. 100 audio channels) for most audio drivers
1322        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
1323          opposed to the LSCP specs
1324        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
1325          reflected the wrong value
1326        - fixed a memory management bug in ASIO driver
1327        - Makefile fix: JACK_CFLAGS wasn't used
1328        - JACK: use jack_client_open instead of the deprecated
1329          jack_client_new
1330        - added (experimental) CoreAudio driver
1331        - applied old fixes to the ASIO driver that were included in the
1332          previous binary release but accidentally never committed to CVS
1333          (fixes #117)
1334        - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
1335          win64)
1336        - VST: added support for sample rate and buffer size changes
1337        - VST: close editor (Fantasia) when the VST is removed
1338        - VST: avoid opening Fantasia more than once for each VST instance
1339        - VST: export main function as "main" on Linux too (fix for
1340          energyXT)
1341        - VST: changed number of output channels from one stereo to 16
1342          stereo
1343        - added channel routing, fxsends and midi maps to the settings
1344          stored in the plugin state
1345        - performance optimization of AudioChannel::MixTo() and
1346          AudioChannel::CopyTo() methods using GCC vector exensions
1347          (if available)
1348        - ASIO fixes: avoid initializing the device twice, avoid throwing
1349          exception when getting parameters from a disconnected device
1350    
1351      * MIDI driver:
1352        - added JACK MIDI driver
1353        - dispatch bank select as ordinary CC as well, the user might seriously
1354          want to (mis)use it for some purpose ("fixed" in all current MIDI
1355          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
1356        - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
1357          CoreMidi or AU
1358        - fixed mingw-w64 compilation error in MME driver
1359        - made program change handling in MIDI thread real-time safe by
1360          moving the logic to a non-RT thread
1361        - fixed minor memory leak in ALSA driver
1362    
1363      * instruments database:
1364        - avoid time consuming samples scanning when adding instruments
1365          to the instruments database
1366        - added support for handling lost files in the instruments database
1367        - Implemented option for adding instruments in separate directories
1368          in the instruments database
1369          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
1370        - work-around for missing fnmatch function on Windows to make
1371          instrument database compilable
1372        - added instrument database support on Windows
1373          works with both standalone mode and VST plugin.
1374          the instruments DB file is located in
1375          %USERPROFILE%\.linuxsampler\instruments.db which allows different
1376          databases for each windows user
1377          if no DB is present it automatically creates the .linuxsampler subdir
1378          and then creates an empty DB
1379        - fixed recursive import, which was broken on Windows
1380    
1381      * Gigasampler format engine:
1382        - fixed a memory leak that could happen when a channel was deleted
1383          while notes were playing
1384        - made it possible to load an instrument even if the audio thread
1385          isn't running
1386        - added partial support for the "Controller Triggered" MIDI rule,
1387          enough for piano gigs with pedal noise samples
1388        - minor fix: only mark FX sends as being modified if really the
1389          respective FX send MIDI controller was used
1390        - added support for GM global device volume SysEx message
1391          (can be selected at compile time to either apply globally to the
1392          whole sampler [default] or only to the sampler channels that are
1393          connected to the respective MIDI input port the SysEx message arrived
1394          on)
1395        - bugfix: notes triggered at position 0 in the audio buffer were
1396          sometimes wrongly killed in the same buffer, causing no sound to
1397          be played
1398        - added support for chromatic / drumkit mode Roland GS Sysex message
1399          which is usally used to switch a part between chromatic sounds and
1400          drumkit sounds (as opposed to their common default setting of MIDI
1401          part 10 being a drumkit part and all other ones chromatic parts), in
1402          LS however one can switch between the first 16 MIDI instrument maps
1403          defined for the sampler
1404        - made it possible to create multiple sample channels even if the
1405          audio thread isn't running
1406        - fixed crash when removing channel with active voices (#116)
1407        - bugfix: on sample reference changes (instrument editor), only
1408          un-cache the respective sample if it's really not used by any
1409          sampler engine anymore
1410        - re-cache samples in case they were changed by an instrument editor,
1411          e.g. when a sample was added while playing (#82)
1412        - fixed hanging notes which occured when note-off event had the exact
1413          same time stamp as the voice's note-on event and occured both in the
1414          same audio fragment cycle (fixes bug #112)
1415        - added support for the "fine tune" and "pitch bend range"
1416          instrument-level gig parameters
1417        - fixed minor artifacts in pitch bend handling
1418        - added support for GS Reset SysEx message
1419        - allow gig files to use unlimited downward pitch shifting
1420        - added a limit check for upward pitch shifting
1421        - bugfix: sometimes, when playing a note twice fast, the second
1422          note was silent
1423        - fixed crash happening when a pitch bend event arrived at the
1424          same time a new instrument was loading
1425    
1426      * LSCP server:
1427        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
1428          react on MIDI data arriving on certain sampler channels (so far only
1429          Note-On and Note-Off events are sent via this LSCP event)
1430        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1431          react on MIDI data arriving on certain MIDI input devices (so far only
1432          Note-On and Note-Off events are sent via this LSCP event)
1433        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
1434          SET DB_INSTRUMENT FILE_PATH
1435        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
1436          frontends to send MIDI messages to specific sampler channel
1437        - added two additional fields to GET FILE INSTRUMENT INFO command -
1438          KEY_BINDINGS and KEYSWITCH_BINDINGS
1439        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1440          was incorrect
1441        - Optimized the retrieval of the MIDI instrument mappings
1442        - added new LSCP command "SET VOICES" to globally alter the maximum
1443          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1444          be triggered respectively
1445        - added new LSCP command "SET STREAMS" to globally alter the maximum
1446          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1447          which will be triggered respectively
1448        - bugfix: retry if "select" returns EINTR (this fixes a crash when
1449          a gigedit file dialog is opened)
1450        - close all connections when LSCPServer is deleted
1451        - hard close of all sockets on exit
1452        - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
1453          driver
1454    
1455      * Bug fixes:
1456        - fixed a crash which occurs when removing a sampler channel waiting
1457          to start instrument loading after another channel
1458        - fixed a crash which occurs when removing a sampler channel with
1459          instrument loading in progress (bug #113)
1460        - fixed termination caused by uncaught exception when adding MIDI
1461          instrument with PERSISTENT load mode
1462        - fixed possible iterator invalidations when resetting the sampler
1463        - fixed memory leaks when issuing the following LSCP commands:
1464          GET AUDIO_OUTPUT_DRIVER INFO
1465          GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
1466          GET MIDI_INPUT_DRIVER INFO
1467          GET MIDI_INPUT_DRIVER_PARAMETER INFO
1468        - fixed possible compilation error when sqlite is not present
1469        - fixed orphaned pointers when setting maximum voices limit (bug #118)
1470        - fixed crash when changing the audio output device of a sampler
1471          channel with loaded instrument and start playing notes
1472        - fixed endless loop in Engine::SuspendAll() (bug #120)
1473        - fixed a low-level atomic load function that was broken on 64-bit
1474          PowerPC, which probably could cause crashes on that platform
1475        - fixed a memory management error which could cause a crash when a
1476          plugin was unloaded
1477        - bugfix: two private structs had the same name, which could cause
1478          problems if the linker chose the wrong constructor
1479        - fixed low-level ConditionServer usage bug that caused lockups on
1480          Windows
1481    
1482    
1483    Version 0.5.1 (6 December 2007)
1484    
1485      * packaging changes:
1486        - added autoconf checks for pthread library
1487        - added autoconf check for pthread bug found on certain NPTL-enabled
1488          glibc versions (see Gentoo bug report #194076)
1489        - added autoconf checks for MS Windows
1490    
1491      * general changes:
1492        - bugfix: the thread used by an editor plugin didn't die when the
1493          editor closed
1494        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1495          out all the space. operator--() did not apply size_mask after
1496          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1497          order to avoid problems with the _NonVolatileReader functions.
1498        - bugfix: Stream.h: added a missing divide by BytesPerSample in
1499          GetWriteSpace(). Since this function is currently only used in
1500          the stream's qsort() compare function, it didn't trigger any
1501          bugs.
1502        - Resampler.h, Synthesizer.h: cubic interpolation now works in
1503          24bit mode too. Faster method to read 24bit words on little
1504          endian machines (x86): replaced 3 byte reads + shifts with a 1
1505          unaligned 32bit read and shift
1506        - experimental support for MS Windows (MIDI input via MME, AUDIO
1507          output via ASIO)
1508        - made handling of SIGINT signal (Ctrl-C) a bit more robust
1509        - support for monitoring the total number of active disk streams
1510          (new LSCP commands: GET TOTAL_STREAM_COUNT,
1511          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1512    
1513      * AUDIO driver:
1514        - added Windows ASIO low latency audio driver
1515    
1516      * MIDI driver:
1517        - added MME Windows MIDI driver
1518    
1519      * LSCP server:
1520        - added support for Windows style path / filenames, however with
1521          forward slash path separators instead of backslash
1522          (i.e. "C:/foo/bar.gig")
1523        - allow naughty liblscp to send non-string device parameters within
1524          apostrophes as well
1525        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1526          "LIST FILE INSTRUMENTS <file>" and
1527          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1528          about an arbitrary instrument file on the system where the sampler is
1529          running on
1530    
1531    Version 0.5.0 (15 October 2007)
1532    
1533      * packaging changes:
1534        - config.h is not going to be installed along with liblinuxsampler's
1535          API header files anymore
1536        - only the API relevant header (and source) files will be exported to
1537          the Doxygen API documentation (explicitly listed in Doxyfile.in)
1538        - added completely new XCode project files for Mac OSX which is now
1539          capable to execute our autoconf environment, thus no need anymore
1540          to maintain the compile time configuration file (osx/version.h) for
1541          OSX manually (patch by Toshi Nagata)
1542        - fixed buggy boolean --enable-foo / --disable-foo configure script
1543          parameters
1544        - global.h now only covers global definitions that are needed for the
1545          C++ API header files, all implementation internal global definitions
1546          are now in global_private.h
1547        - atomic.h is not exposed to the C++ API anymore
1548        - no need to include config.h anymore for using LS's API header files
1549        - fixed warnings in API doc generation
1550    
1551      * general changes:
1552        - replaced the old, confusing MIDI program change mechanism by a
1553          flexible MIDI instrument mapper which allows to map arbitrary
1554          (MIDI bank, MIDI program) pairs with arbitrary
1555          (engine type, instrument file, file index) triplets which will be
1556          loaded on the respective channel when such MIDI program change
1557          messages arrive, beside that, each entry allows to define a life-time
1558          strategy for the instrument, so the user can define whether the
1559          instrument should i.e. be permanently loaded (to be able to switch
1560          quickly among sounds) or i.e. loaded just on demand when the
1561          respective program change arrives (to safe RAM space), as well as a
1562          global volume factor for each entry, so the user can adjust the volume
1563          dynamic of his mapped instrument collection without having to modify
1564          the instrument files, also one can manage arbitrary amount of such
1565          MIDI instrument maps and assign each sampler channel individually
1566          a certain map, so that i.e. separation of normal instruments and
1567          drumkits is possible
1568        - new notification events for tracking changes to audio/MIDI devices,
1569          MIDI instrument maps, MIDI instruments, FX sends, global volume.
1570        - sampler was limited to load max. 200 instruments in the background
1571          due to a constant size RingBuffer FIFO which is now replaced by a
1572          dynamic (unlimited) size std::list FIFO
1573        - added FX sends, these allow to route audio signals to arbitrary audio
1574          output channels for being processed by external effect processors
1575          (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1576          controllers
1577        - global (sampler wide) volume can now be controlled at runtime
1578        - Implemented new, improved notification system
1579        - fixed compilation errors regarding OSX
1580          (patch by Toshi Nagata)
1581        - implemented instruments database
1582        - added support for escape sequences to the instruments database
1583        - added highly experimental support for on-the-fly instrument editing
1584          within the sampler's process (by using instrument editor plugins),
1585          you'll notice the new "Registered instrument editors:" message on
1586          startup, added a new LSCP command:
1587          "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1588          to spawn a matching instrument editor for the instrument on the
1589          given sampler channel, the plugin path can be overridden at compile
1590          time with ./configure --enable-plugin-dir=/some/dir
1591        - added experimental code for synchronizing instrument editors hosted
1592          in the sampler's process to safely edit instruments while playing
1593          without a crash (hopefully) by either suspending single regions
1594          wherever possible or if unavoidable whole engine(s)
1595        - fixed several issues in fundamental "Thread" class: set scheduling
1596          policy and priority on thread level, set a minimum stack size for
1597          thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1598          threads simply inherited properties of starting thread instead of
1599          setting their own policy and priority
1600        - minor fix in our automatic stack trace mechanism on crashes, the
1601          main process did not wait for the stack trace process to finish
1602          its output
1603        - fixed some minor memory leaks
1604        - reenabled assembly features support, at the moment only for
1605          enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1606        - minor assembly fix in x86 features detection (don't use the PIC
1607          register, to avoid relocations in the text segment at runtime)
1608        - POSIX callback functions of Thread.h are hidden
1609    
1610      * MIDI driver:
1611        - dispatch bank select (MSB and LSB) messages
1612    
1613      * audio driver:
1614        - the ALSA audio output driver parameters now reflect the correct
1615          parameter value ranges for the respective selected sound card
1616          (patch by Till Wimmer, a bit fixed and extended)
1617    
1618      * Gigasampler format engine:
1619        - if a filter is used and EG2 finishes before EG1, let the voice
1620          die when EG2 has finished (this fixes a problem with clicks and
1621          voice starvation for some gigs)
1622        - playback is no longer disabled during instrument loading
1623        - all notes playing on a channel that changes its instrument keep
1624          playing with the old instrument until they get a note off
1625          command
1626        - EG fix: a release value of zero could cause noises or crash
1627        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1628        - EG fine tuning: when attack is zero the EG starts at a level
1629          above max sustain level, which means that there is a decay phase
1630          even if sustain is 100%
1631        - more EG fixes: the level could sometimes go below zero and cause
1632          noises or crashes
1633        - minor fix of EGDecay (patch by Toshi Nagata)
1634        - fixed compiler error when --enable-override-filter-type was
1635          supplied to the configure script (fixes #46)
1636        - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1637          instead of a fix value
1638        - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1639          127 (solo mode) only kill voices if the respective mode really
1640          changed
1641    
1642      * LSCP server:
1643        - fixed compile time error for old Bison versions
1644          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1645        - parser now supports extended ASCII character set
1646          (up to ASCII code 255, i.e. includes now umlauts and accents)
1647        - filename arguments in LSCP commands now allow to use escape
1648          sequences, that is directly literal as one of: \', \", \\, \n, \r,
1649          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1650          code value like \xf2) (fixes bug #24)
1651        - the following LSCP commands now also support escape sequences for at
1652          least one of their text-based parameters (i.e. name, description):
1653          "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1654          "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1655          "SET DB_INSTRUMENT_DIRECTORY NAME",
1656          "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1657          "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1658          "FIND DB_INSTRUMENT_DIRECTORIES"
1659        - returns verbose syntax errors (line and column where syntax error
1660          occured, the unexpected character and the actually expected, possible
1661          character(s), the latter only if less than 5 possibilities)
1662        - made sure that LSCP syntax is not affected by gigedit locale
1663          settings
1664        - bugfix regarding strings parameter lists: all comma separated lists
1665          of strings were treated as being one string containing commas
1666          (fixes #57)
1667    
1668      * Bug fixes:
1669        - fixed crash occurring on certain LSCP scripts (Bug 39)
1670        - another thread safety fix for lscp "load engine" and "set
1671          channel audio output device"
1672        - fixed a crash which occurs when reassigning the same engine
1673          on a sampler channel with connected MIDI device
1674        - fixed a crash which occurs when changing the number of ports of a MIDI
1675          device connected to a sampler channel to number less then or equal
1676          to the index of the port to which the sampler channel is connected.
1677        - The previous bindings were not been disconnected when altering
1678          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1679          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1680        - The active stream/voice count statistic was incorrect.
1681        - notification events were not been sent for some sampler
1682          channel changes
1683        - added default min and max values to restrict the number of allowed
1684          audio output channels and MIDI input ports
1685        - the connection to the PCM interface is now closed when destroying
1686          an audio output device
1687        - files with slash in their path or filename could not be loaded
1688    
1689      * test cases:
1690        - updated and fixed (haven't been touched in a while)
1691    
1692    Version 0.4.0 (24 November 2006)
1693    
1694      * packaging changes:
1695        - changed deprecated copyright attribute to license; added ldconfig
1696          to post-(un)install steps; added devel package for liblinuxsampler;
1697          to linuxsampler.spec (RPM)
1698        - install necessary development header files for allowing 3rd party
1699          applications to link against liblinuxsampler
1700        - liblinuxsampler's API documentation can be generated with 'make docs'
1701          (Doxygen required)
1702        - added benchmark to automatically detect the best triangle LFO
1703          implementation (currently either an integer math solution or a
1704          di-harmonic approximation), automatic detection can be overriden
1705          with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1706          configure script argument though (mandatory for cross-compilation)
1707        - do not automatically pick optimized gcc flags if the user already
1708          provided some on his own (as CXXFLAGS)
1709        - added compile time option to disable processing of All-Notes-Off MIDI
1710          messages
1711        - added compile time options to allow disabling the various audio and
1712          MIDI drivers
1713        - fixed automatic GCC CPU switch detection on PPC
1714          (patch by Ebrahim Mayat)
1715    
1716      * Gigasampler format engine:
1717        - extensive synthesis optimization
1718          (reimplementation of EGs and LFO(s), removed synthesis parameter
1719          prerendering and the synthesis parameter matrix in general, splitting
1720          each audio fragment into subfragments now where each subfragment uses
1721          constant pitch and filter coefficients. The volume coefficient is
1722          linearly interpolated inside a subfragment, unless
1723          --disable-interpolate-volume is set.)
1724        - fine tuning of the EG modulation parameters
1725        - improved filter cutoff calculation by adding support for the
1726          following gig parameters: Cutoff freq (used when no cutoff
1727          controller is defined), Control invert, Minimum cutoff, Velocity
1728          curve and Velocity range. The keyboard tracking now scales
1729          cutoff frequency instead of resonance.
1730        - added support for gig parameter Resonance.
1731        - fixed bug in sysex handling (patch by Juan Linietsky)
1732        - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1733          which can be overridden with --enable-global-attenuation
1734        - EG fixes: made the length of "attack hold" stage more
1735          accurate. Release stage can now start before attack stage
1736          ends. Cancel release didn't work when sustain was zero. Attack
1737          time now has a minimal value to prevent clicks.
1738        - fixed pitch changes larger than one octave
1739        - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1740        - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1741          all modes can be altered via standard GM messages, that is CC5 for
1742          altering portamento time, CC65 for enabling / disabling portamento
1743          mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1744        - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1745          parameter) and crossfade
1746        - added support for the "attenuation controller threshold" gig
1747          parameter
1748        - added smoothing of volume changes caused by control change
1749          messages
1750        - sample loop parameters are now taken from the DimensionRegion
1751          instead of the wave chunk
1752        - fixed keyswitching for v3 gigs with a number of keyswitch splits
1753          not equal to a power of two
1754        - reimplementation of the filter algorithm. The new filter is more
1755          accurate and supports all gig filter types, including bandreject
1756          and lowpass turbo.
1757        - real support for 24 bit samples - samples are not truncated to
1758          16 bits anymore
1759        - support for aftertouch (channel pressure, not polyphonic
1760          aftertouch)
1761        - LFO1 behaviour fixed (dampening from max volume instead of
1762          amplifying from 0)
1763    
1764      * LSCP server:
1765        - fixed application exit on broken pipe error (fixes bug #20)
1766        - fixed the notification messages delay due to lack of
1767          network activity (fixes bug #26)
1768        - fixed parser bug which occured on space(s) within device parameters
1769          (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1770    
1771      * audio driver:
1772        - added aRts audio output driver (by no means RT safe)
1773    
1774      * MIDI driver:
1775        - fixed legacy sysex code which caused dispatching of MIDI SysEx
1776          messages several times instead of once
1777        - API extension for MIDI drivers which already supply exact time stamps
1778          for events (i.e. for offline rendering based MIDI drivers)
1779        - added checks for bad MIDI data
1780    
1781      * linuxsampler application:
1782        - show available sampler engine types on startup
1783    
1784      * general changes:
1785        - support for muting sampler channels and solo mode of the same, two new
1786          LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1787          fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1788          introduced for this, the behavior is the same like on a mixer console
1789          (patch by Grigor Iliev, a bit adjusted). Also added configure option
1790          --enable-process-muted-channels which can be used to enable the
1791          processing of muted channels.
1792        - support for sostenuto pedal
1793        - support for monitoring the total number of active voices
1794          (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1795          SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1796        - fixed some memory management errors
1797        - fixed some concurrency problems that could lead to crashes when
1798          LSCP commands were executed
1799        - fixed crash when instrument loading failed previously on the same
1800          sampler channel (fixes bug #36)
1801    
1802    Version 0.3.3 (15 July 2005)
1803    
1804      * packaging changes:
1805        - fixed compilation with gcc 4.0
1806    
1807      * Gigasampler format engine:
1808        - LFO preprocessing was performed even though the respective LFO was
1809          disabled by the instrument patch (minor efficiency fix)
1810        - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1811          for volume ramp downs in the same fragment (needed for current voice
1812          stealing implementation) then simply inform the user with a warning
1813          about possible click sounds and reduce the volume ramp down
1814          appropriately instead of cancelling the audio device connection
1815    
1816    Version 0.3.2 (24 June 2005)
1817    
1818    * packaging changes:    * packaging changes:
1819      - updated autotools build files to compile on OS X      - updated autotools build files to compile on OS X
# Line 15  Version CVS HEAD (?) Line 1830  Version CVS HEAD (?)
1830      - volume of release triggered samples now depends on note-on velocity,      - volume of release triggered samples now depends on note-on velocity,
1831        note length and gig parameter "release trigger decay" instead of        note length and gig parameter "release trigger decay" instead of

1833      - revised voice stealing (fixes crash caused by voice stealing)      - revised voice stealing
1834          (fixes crash and endless loop caused by voice stealing)
1835        - don't reset scale tuning on instrument or audio output device change
1836        - handle key group conflicts right at the beginning of each fragment
1837          instead of when the respective voice is actually launched
1838          (fixes undefined behavior if stolen voices belonged to a key group -
1839          this case was followed by a "killed voice survived" error message)
1840        - fixed minor issue with null/silence samples
1841          (those stole voices even though they don't need a voice at all which
1842          resulted in "voice stealing didn't work out" messages)
1843        - don't reset volume, pan, pitch and MIDI controller values on
1844          instrument or audio output device change
1845    
1846    * LSCP server:    * LSCP server:
1847      - fixed some crashes (patch by Grigor Iliev, fixes #19)      - fixed some crashes (patch by Grigor Iliev, fixes #19)
1848        - fixed LSCP event "CHANNEL_INFO" notification
1849          (e.g. did not notify on volume changes or MIDI program change events)
1850    
1851      * linuxsampler application:
1852        - added command line parameters --lscp-addr and --lscp-port to override
1853          default IP address and port of LSCP server
