# Line 1  Line 1 
1  Version CVS HEAD (?)  Version SVN trunk (?)
2    
3    * plugin changes:    * GigaStudio/Gigasampler format engine:
4      - LV2 Persist + Files support (patch by David Robillard)      - Use libgig's new IO-per-thread feature to avoid file I/O concurrency
5          issues with .gig file.
6        - Use libgig's new method gig::File::GetSample() with method
7          gig::File::CountSamples() instead of now deprecated
8          gig::File::GetFirstSample() / gig::File::GetNextSample() pair.
9    
10    Version 2.2.0 (9 May 2021)
11    
12      * general changes:
13        - Fixed compiler error in Pool.h.
14        - Require C++14 compiler support.
15        - Autoconf: Added m4/ax_cxx_compile_stdcxx.m4 macro which is used
16          for checking in configure for C++14 support (as mandatory
17          requirement) and automatically adds compiler argument if required
18          (e.g. -std=C++14).
19        - RTMath: Implemented floating point comparison methods
20          fEqual32(float,float) and fEqual64(double,double) which take the
21          expected floating point tolerances into account.
22        - Added public API C++ class "LFO", which is a cluster class encapsulating
23          all the sampler's LFO implementations to be used by 3rd party applications
24          (e.g. by Gigedit).
25        - Added int math square LFO implementation.
26        - Added int math saw LFO implementation.
27        - Added numeric complex nr sine LFO implementation.
28        - Marked class LFOTriangleDiHarmonic as deprecated
29          (will be removed in future).
30        - Added LFOAll.h which includes all LFO implementation's header files.
31        - Refactored LFO class names and their file names (PulseLFO -> LFOPulse,
32          LFOSawIntMath -> LFOSawIntMathNew, SawLFO -> LFOSawIntMathOld,
33          SineLFO -> LFOSineBuiltinFn, LFOSine -> LFOSineNumericComplexNr,
34          SquareLFO -> LFOSquarePulse and separated the latter to its own header
35          file).
36        - Renamed type LFOSigned -> LFOTriangleSigned.
37        - Renamed type LFOUnsigned -> LFOTriangleUnsigned.
38        - Using now cubic interpolation as resampling algorithm by default; and
39          linear interpolation is deprecated now.
40        - Event:Init(): memset() entire Event::Param union to zero instead of trying
41          to do that for its individual members; the latter became error prone due
42          to the union's growing complexity meanwhile.
43        - EngineChannel: Overhaul of RPN/NRPN related methods: Added new
44          *Rpn*Parameter*() methods as replacement for previous *Rpn*Controller*()
45          methods and marked the old ones as deprecated; and likewise added new
46          *Nrpn*Parameter*() methods as replacement for previous *Nrpn*Controller*()
47          methods and marked those old ones deprecated as well.
48        - Added support for MIDI CC #38 (data entry LSB): this allows higher value
49          resolution for certain (e.g. hard coded) RPN and NRPN parameters.
50        - Implemented support for compressed RPN/NRPN message sequences (that is to
51          allow processing MIDI data entry messages without always having to be
52          preceded strictly by RPN/NRPN parameter selection messages on each value
53          change).
54        - Added support for MIDI CC #96 (data increment) and MIDI CC #97 (data
55          decrement).
56        - Added support for 'null function RPN/NRPN' (which is RPN/NRPN parameter
57          MSB=127 and LSB=127) and which is disabling subsequent data
58          entry/increment/decrement CC messages.
59        - Fixed crash when editing key groups (a.k.a. exclusive groups) with an
60          instrument editor.
61        - Fixed playing noise at the end of a disk stream under certain conditions.
62        - Fixed potential crash with high pitch at end of RAM playback.
63        - Added configure checks whether C++ compiler supports so called
64          'designated initializers'.
65        - Added global backtraceAsString() function for debugging purposes
66          (POSIX systems only, no Windows implementation yet).
67        - Thread class: Added new methods pushCancelable(), popCancelable(), name(),
68          nameOfCaller() and setNameOfCaller().
69        - configure: Always check for availability of pthread_testcancel() and use
70          it if so (previously it was only used if explicitly enabled by configure
71          option).
72        - Thread class: raise compiler warning if pthread_testcancel() is not
73          available, because it can lead to deadlocks.
74        - Mutex class: Implemented optional bug detection and deadlock debugging
75          features.
76        - Ref<> class is now thread safe (as lock-free and wait-free
77          implementation).
78        - Fixed compilation error with Bison >= 3.6.0.
79        - Fixed rare crash when switching between instruments that had instrument
80          scripts loaded.
81        - Allow EffectChain::InsertEffect() as alternative to
82          EffectChain::AppendEffect() (i.e. with index equal to current chain size).
83        - ConstCapacityArray class: Fixed bug in remove() method.
84        - Fixed crash on certain MIDI RPN and NRPN messages that occurred if no
85          real-time instrument script was loaded.
86    
87      * Real-time instrument scripts:
88        - Added method ScriptVM::setExitResultEnabled() which allows to
89          explicitly enable the built-in exit() function to optionally accept
90          one function argument; the value of the passed exit() function
91          argument will then become available by calling
92          VMExecContext::exitResult() after script execution.
93        - 64 bit support for NKSP integer scripts variables (declare $foo).
94        - Variable names, function names and preprocessor condition names must start
95          with a regular character (a-z or A-Z); starting them with a digit or
96          underscore is not allowed.
97        - NKSP parser fix: equal comparison operator "=" and not equal comparison
98          operator "#" must only accept integer operands.
99        - NKSP language: Implemented support for standard units like Hertz, seconds,
100          Bel including support for metric unit prefixes; so one can now e.g.
101          conveniently use numbers in scripts like "5us" meaning "5 microseconds",
102          or e.g. "12kHz" meaning "12 kilo Hertz", or e.g. "-14mdB" meaning
103          "minus 14 Millidecibel", or e.g. "28c" meaning "28 cents" (for tuning).
104        - NKSP language: Introduced "final" operator "!" which is specifically
105          intended for synthesis parameter values to denote that the synthesis
106          parameter value is intended to be the "final" value for that synthesis
107          parameter that should explicitly be used by the engine and thus causing
108          the sampler engine to ignore all other modulation sources for the same
109          synthesis parameter (like e.g. LFO, EG); by simply prefixing a value,
110          variable or formula with this new "!" operator the expression is marked as
111          being "final".
112        - NKSP script editor API: Added support for detecting standard unit tokens
113          and their potential metric prefix token.
114        - NKSP language: Added support for NKSP real number literals and
115          arithmetic operations on them (e.g. "(3.9 + 2.9) / 12.3 - 42.0").
116        - NKSP language: Added support for NKSP real number (floating point) script
117          variables (declare ~foo).
118        - NKSP language: Added support for NKSP real number (floating point) array
119          script variables (declare ?foo[]).
120        - Built-in script function "message()" accepts now real number argument as
121          well.
122        - Added built-in script function "real_to_int()" and its short hand form
123          "int()" for casting from real number to integer in NKSP scripts.
124        - Added built-in script function "int_to_real()" and its short hand form
125          "real()" for casting from integer to real number in NKSP scripts.
126        - Allow built-in exit() function to potentially accept real number type
127          argument as well.
128        - Built-in script functions may have a different return type depending on
129          the arguments passed to the function.
130        - Built-in script function "abs()" optionally accepts and returns real
131          number.
132        - Built-in script functions "min()" and "max()" optionally accept real
133          number arguments and return real number as result in that case.
134        - NKSP VM API: Allow units and 'final'ness to be returned as result from
135          built-in functions (added methods VMFunction::returnUnitType() and
136          VMFunction::returnsFinal() for that purpose which must be implemented by
137          built-in function implementations).
138        - NKSP language: Allow metric unit prefixes of numeric scalar and array
139          variables to be changed freely at runtime (unlike unit types like Hz etc.
140          which are still sticky, parse-time features of variables which cannot be
141          changed at runtime for the intentional sake of determinism).
142        - NKSP language: 'final' values are prohibited for array variables for now
143          (attempt causes a parsers error).
144        - NKSP language: expressions with unit types (e.g. Hz) are prohibited for
145          conditions of runtime control structures like if(), while(), select()
146          (attempt causes a parser error).
147        - NKSP VM API: Allow built-in functions to perform their own, individual
148          parse time checks of arguments going to be passed to the function at
149          runtime (added method VMFunction::checkArgs() for that purpose).
150        - NKSP language: raise parser warning if only one operand of binary
151          operators (like logical 'or' comparison) contain a 'final' value (because
152          it would always yield in a 'final' result in such cases).
153        - NKSP language: Allow comparison (=, #, <, >, <=, >=) of values with
154          different metric unit prefixes, which will behave as expected (e.g.
155          result of expression '1000us < 2ms' is true).
156        - NKSP language: Allow adding values with different metric unit prefixes
157          (e.g. result of expression '100Hz + 5kHz' is '5100Hz').
158        - NKSP language: Allow subtracting values with different metric unit
159          prefixes (e.g. result of expression '1ms - 20us' is '980us').
160        - NKSP language: Allow multiplying with any metric unit prefixes
161          (e.g. result of expression '2k * 3ms' is '6s'), however multiplications
162          with unit types on both sides (e.g. '2s * 2s') is still prohibited since
163          we don't have any considerable practical use for a term like '4s^2'
164          (hence any attempt multiplying two unit types still causes parser error).
165        - NKSP language: Allow dividing by any metric unit prefixes and allow
166          division of same unit type on both sides (e.g. expression '8kHz / 1000Hz'
167          yields in unit free result '8'). So this is now a way to cast units away
168          e.g. for passing the result to other expressions, certain function calls
169          or variables which are not accepting any units (or that specific unit).
170        - NKSP language: integer arrays and real number arrays can now be converted
171          to strings (e.g. for dumping their content with message() calls for
172          script debugging purposes).
173        - NKSP language: expressions and variables with units are now correctly
174          casted to strings (e.g. with message() calls).
175        - NKSP language: comparing real numbers for equalness (e.g. '~foo = 3.1') or
176          unequalness (e.g. '~foo # 3.1') is now less strict and takes the expected
177          floating point tolerances into account.
178        - NKSP VM API: Added methods VMScalarNumberExpr::evalCastInt() and
179          VMScalarNumberExpr::evalCastReal().
180        - NKSP VM API: Added base class 'VMNumberArrayExpr' for classes
181          'VMIntArrayExpr' and 'VMRealArrayExpr'.
182        - NKSP VM API: replaced all unitPrefix() (parse time) methods by
183          unitFactor() (runtime) methods.
184        - Built-in function "exit()" supports now returning units and 'final'ness
185          for test cases.
186        - The following built-in functions support now units as well: "abs()",
187          "random()", "inc()", "dec()", "in_range()", "min()", "max()",
188          "real_to_int()", "int()", "int_to_real()" and "real()".
189        - Built-in functions "array_equal()", "search()" and "sort()" support now
190          real number arrays (correctly) as well.
191        - Added individual parse time checks of arguments to be passed to built-in
192          functions "random()", "inc()", "dec()", "in_range()", "min()", "max()",
193          "array_equal()" and "search()" specific for their individual purposes.
194        - NKSP VM refactoring: Renamed all methods, functions and classes matching
195          pattern *ScalarNumber* to simply *Number* (that is i.e. classes
196          VMScalarNumberExpr -> VMNumberExpr, ScalarNumberExpr -> NumberExpr,
197          ScalarNumberVariable -> NumberVariable, ScalarNumberBinaryOp ->
198          NumberBinaryOp, VMScalarNumberResultFunction -> VMNumberResultFunction,
199          method VMExpr::asScalarNumberExpr() -> VMExpr::asNumber(), function
200          isScalarNumber() -> isNumber()).
201        - NKSP VM API: Added 4 overridden methods to class VMNumberExpr:
202          evalCastInt(MetricPrefix_t), evalCastInt(MetricPrefix_t,MetricPrefix_t),
203          evalCastReal(MetricPrefix_t), evalCastReal(MetricPrefix_t,MetricPrefix_t)
204          as convenient methods for automatically converting values to expected
205          metric value basis.
206        - Built-in function "wait()" accepts now both integers and real numbers as
207          argument.
208        - NKSP VM API cleanup: Get rid of legacy method
209          VMFunction::argType(vmint iArg) which was already superseded by its new
210          replacement VMFunction::acceptsArgType(vmint iArg, ExprType_t type).
211        - NKSP parser: if wrong argument type was passed to a built-in function and
212          that built-in function accepts more than one data type for the argument,
213          then show all supported data types as parser error message.
214        - Built-in function "play_note()" accepts now real numbers and seconds as
215          unit type as well for its 3rd and 4th function arguments.
216        - The following built-in functions accept now real numbers as well for their
217          2nd function argument: "change_vol()", "change_tune()", "change_cutoff()",
218          "change_attack()", "change_decay()", "change_release()",
219          "change_sustain()", "change_cutoff_attack()", "change_cutoff_decay()",
220          "change_cutoff_sustain()", "change_cutoff_release()",
221          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
222          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
223          "change_pan_time()", "fade_in()", "fade_out()", "change_play_pos()".
224        - Fixed built-in function "change_play_pos()" not having accepted metric
225          prefixes at all.
226        - Fixed the following built-in functions having misinterpreted values given
227          with unit type (for their 2nd argument) as if they were relative values
228          (that is as if they were passed without a unit type): "change_attack()",
229          "change_decay()", "change_release()", "change_cutoff_attack()",
230          "change_cutoff_decay()", "change_cutoff_release()".
231        - Fixed the following built-in functions having applied completely wrong
232          'final' values: "change_sustain()", "change_cutoff_sustain()" (since the
233          respective EGs being their modulation sink assume uint data type with
234          value range 0..1000 instead of 0.0..1.0.
235        - Added individual parse-time checks of function arguments for the following
236          built-in functions: "play_note()", "note_off()", "set_event_mark()",
237          "delete_event_mark()", "by_marks()", "change_cutoff()", "change_attack()",
238          "change_decay()", "change_release()", "change_cutoff_attack()",
239          "change_cutoff_decay()", "change_cutoff_release()",
240          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
241          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()" and
242          "change_pan_time()".
243        - Don't abort function call if unit type was used and at the same time
244          'final' operator was omitted for the primary value argument of the
245          following built-in functions: "change_cutoff()", "change_attack()",
246          "change_decay()", "change_release()", "change_cutoff_attack()",
247          "change_cutoff_decay()", "change_cutoff_release()",
248          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
249          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
250          "change_pan_time()", instead imply 'final'ness at runtime and raise an
251          appropriate parser warning at parse time.
252        - Added built-in real number functions "round()", "ceil()", "floor()",
253          "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()", "sin()",
254          "cos()", "tan()", "asin()", "acos()", "atan()".
255        - Added built-in script real number constant "~NI_MATH_PI".
256        - Added built-in script real number constant "~NI_MATH_E".
257        - NKSP language: Allow unary '+' operator.
258        - Added built-in script functions "msb()" and "lsb()".
259        - NKSP language: Added support for RPN event handler
260          ("on rpn ... end on" in instrument scripts).
261        - NKSP language: Added support for NRPN event handler
262          ("on nrpn ... end on" in instrument scripts).
263        - Added built-in read-only variables "$RPN_ADDRESS" and "$RPN_VALUE" which
264          may be read from the new RPN/NRPN script handlers to get the (N)RPN
265          parameter that had been changed and its new value.
266        - Added built-in const variables "$NI_CB_TYPE_RPN" and "$NI_CB_TYPE_NRPN"
267          which are identifying the new (N)RPN handlers as such at script runtime.
268        - Implemented built-in script function "set_rpn()".
269        - Implemented built-in script function "set_nrpn()".
270        - Fix: built-in functions returning an array type were broken and caused a
271          crash when the built-in function's (supposed to be array) result value was
272          used by the script VM.
273        - Removed upper value constraint for 2nd argument of built-in functions
274          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
275          "change_pitch_lfo_freq()","change_reso()", "change_cutoff()",
276          "change_amp_lfo_depth()", "change_cutoff_lfo_depth()" and
277          "change_pitch_lfo_depth()", to allow e.g. passing value 2000000 to double
278          the LFO frequency / resonance / cutoff frequency.
279        - Reduced code involved for parsing NKSP variable declarations by using 2
280          generalized grammar rules with optional components (i.e. optional value
281          assignment and optional variable qualifiers) instead of previous linear
282          combinations of grammar rules, which also fixes some edge case.
283        - NKSP language parser: track code block locations also by a) raw byte
284          position in NKSP source code string and b) length of that code block in
285          bytes (along to the already existing code block tracking by line/column);
286          and added appropriate new members to public C++ API classes like
287          'firstByte' and 'lengthBytes' to class VMSourceToken and struct CodeBlock.
288        - NKSP language: Added support for 'patch' variable qualifier (capture their
289          locations and allow replacement of their assignment expression via VM C++
290          API).
291        - Fixed incorrect EG times if standard measuring unit was passed to built-in
292          functions "change_attack()", "change_decay()" or "change_release()".
293        - Fixed intermediate function result values never having reflected any
294          standard measuring unit type.
295        - Fixed re-entrant issue with function calls which caused wrong result
296          values if the same function was called multiple times in a term
297          (specifically if metric prefixes were used).
298        - NKSP language: Just throw a warning, not an error if an array variable of
299          size zero was declared.
300        - NKSP language: Allow omitting explicit array size on array variable
301          declaration if combined with immediate value assignment
302          (e.g. declare %foo[] := ( 1, 2, 3 ) ).
303        - NKSP language: emit warning if an array variable was declared with bigger
304          array size than amount of initial values been assigned, and initialize the
305          missing array elements with zero in this case.
306        - Fixed built-in NKSP exit() function to behave as return statement.
307        - NKSP parser: Fixed crash if unary '-' operator was used on a non-number
308          data type.
309        - NKSP VM: Fixed the "release" handler being executed too often under
310          certain situations if polyphonic data was passed from "note" handler to
311          "release" handler.
312        - Fixed memory leak in NKSP parser: string tokens were allocated as C
313          strings and never freed.
314        - Fixed incorrect polyphonic data transfer from wrong note handler to
315          release handler; which also fixes no release handler being executed
316          sometimes, and due to the latter it also fixes potential crashes as some
317          polyphonic script events were never released and the engine hence was
318          running out of free script events.
319        - Fixed crash when handling array results of built-in functions
320          (e.g. "num_elements(by_marks($MARK_1)").
321        - NKSP VM: Fixed dead note events not been removed from user's event groups
322          (i.e. causing incorrect behaviour of built-in NKSP functions by_marks()
323          and set_event_mark() after max. size of event group list was exhausted).
324    
325      * test cases:
326        - Fixed compiler errors in test cases.
327        - Updated README for how to compile & run test cases.
328        - Updated test case
329          MutexTest::testDoubleLockStillBlocksConcurrentThread() to latest
330          expected behaviour of the Mutex class implementation (recursive
331          mutex type).
332        - Added test cases for NKSP core language aspects and core built-in
333          functions.
334        - Fixed thread tests segfaulting on Linux.
335        - NKSP: Added real number test cases for built-in functions exit(),
336          int_to_real(), real(), real_to_int() and int(), as well as for the
337          plus, minus and negate language operators.
338        - Added massive amount of NKSP test cases for standard measuring units and
339          'final' operator usage cases.
340        - Added NKSP test cases for (floating point tolerance aware) real number
341          equalness / unequalness comparison.
342        - Added NKSP int array and real array tests for value assignment and
343          initialization of arrays.
344        - Added NKSP test cases for built-in functions "round()", "ceil()",
345          "floor()", "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()",
346          "sin()", "cos()", "tan()", "asin()", "acos()", "atan()".
347        - Added NKSP test cases for unary '+' operator.
348        - Added NKSP test cases for core built-in variables.
349        - Added thorough NKSP test cases for variable declarations.
350    
351      * GigaStudio/Gigasampler format engine:
352        - LFOTriangleIntMath and LFOTriangleIntAbsMath: Fixed FlipPhase=true
353          behaviour for start_level_mid.
354        - Changed LFO start levels: LFO1 and LFO2 both to mid, LFO3 to max. start
355          level (see discussion "GigaStudio LFO compatibility" on mailing list
356          from 2019-09-26 for details).
357        - Changed default wave form for all 3 LFOs to sine (instead of triangle;
358          see discussion "GigaStudio LFO compatibility" on mailing list from
359          2019-09-26 for details).
360        - Format extension: Added support for different LFO wave forms (currently
361          either sine [default], triangle, saw or square).
362        - Format extension: Added support for LFO phase displacement (0°..360°).
363        - Format extension: Added support for flipping LFO polarity on LFO 3
364          (in the original gig format this was only available for LFO 1 and LFO 2).
365        - Format extension: Support for additional filter types:
366          lowpass 1/2/4/6-pole, highpass 1/2/4/6-pole, bandpass 2-pole,
367          bandreject 2-pole.
368        - Fixd potential crash with polynomial interpolator and max. pitch.
369        - If minimum cutoff is defined, remap cutoff controller CC values to really
370          span the entire possible cutoff range (and avoiding a dead controller
371          zone).
372        - Implemented support for loading instrument scripts with 'patch' variables
373          (by patching these script variables with potentially overridden ones by
374          gig Instrument).
375    
376      * SFZ format engine:
377        - Fixed support for regions with loccN/hiccN conditions on more than one
378          MIDI controller.
379        - Fixed internal opcode 'xfin_hivel' falsely being set by user opcode
380          'xfin_lovel' (patch by Christian Czezatke).
381    
382      * Benchmarks:
383        - Fixed benchmarks/triang.cpp falsely having favoured "int math abs"
384          algorithm (since result of 2nd run was not accumulated).
385        - Added benchmark for saw wave (benchmarks/saw.cpp).
386        - Added benchmark for sine wave (benchmarks/sine.cpp).
387        - Added benchmark for square wave (benchmarks/square.cpp).
388        - Increased amount of benchmarks runs by factor 6 to achieve benchmark times
389          which are large enough on modern systems.
390    
391    Version 2.1.1 (27 Jul 2019)
392    
393      * Real-time instrument scripts:
394        - Fixed behavior of built-in NKSP functions change_sustain(),
395          change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain()
396          and change_cutoff_release().
397    
398      * general changes:
399        - Only play release trigger samples on sustain pedal up if this behaviour
400          was explicitly requested by the instrument (otherwise only on note-off).
401        - Fixed compiler warnings.
402        - Fixed compilation error when cross-compiling to Mac.
403        - FX Sends: Provide more useful error messages on routing problems
404          (see bug #169).
405        - LSCP doc: Be more clear describing the two distinct approaches
406          of using external vs. internal effects (see bug #169).
407        - "optional" class: Fixed comparison operators.
408    
409      * Gigasampler/GigaStudio format engine:
410        - Format extension: If requested by instrument then don't play release
411          trigger sample on note-off events.
412    
413      * SFZ format engine:
414        - Fixed memory leak when releasing samples
415          (fixes bug #307, patch by Jacek Roszkowski)
416        - Fixed potential crash when a sample is shared by more than one region
417          (fixes bug #308, patch by Jacek Roszkowski).
418        - Opcode 'sample': Added support for built-in sample '*silence'
419          (fixes bug #310, patch by Jacek Roszkowski).
420    
421    Version 2.1.0 (25 Nov 2017)
422    
423      * SFZ format engine:
424        - added support for <global>, <master> and #define (patch by Alby M)
425        - Removed code duplication in SFZ file loading code.
426        - Added support for sfz extension opcode 'script' which may be used to
427          load real-time instrument script file (NKSP script language).
428        - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
429        - Fixed unintended volume fade-in of voices under certain conditions.
430        - sfz parser: allow missing space between header and opcode
431    
432      * Gigasampler/GigaStudio format engine:
433        - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
434          cutoff settings.
435        - Got rid of resembling an ancient GSt misbehavior which did not pitch at
436          all if an up-pitch of more than 40 semi tones was requested (I don't
437          think there is any stock gig sound that requires this behavior to
438          resemble its original sound).
439        - Added support for controlling whether the individual EGADSR stages may
440          be aborted (as LinuxSampler extension to the original GigaStudio 4
441          format).
442    
443      * general changes:
444        - fixed printf type errors (mostly in debug messages)
445        - use unique_ptr instead of auto_ptr when building with C++11
446        - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
447          allowing to sort data efficiently in real-time safe manner.
448        - RTList class: added methods for moving/inserting elements to arbitrary
449          position within a list.
450        - RTList class: added method fromPtr() for creating an Iterator object from
451          a raw element pointer.
452        - Attempt to partly fix resetting engine channels vs. resetting engine, an
453          overall cleanup of the Reset*(), ConnectAudioDevice(),
454          DisconnectAudioDevice() API methods would still be desirable though,
455          because the current situation is still inconsistent and error prone.
456        - Active voices are now internally grouped to "Note" objects, instead of
457          being directly assigned to a keyboard key. This allows more fine graded
458          processing of voices, which is i.e. required for certain instrument
459          script features.
460        - Fix: Release trigger voices were not spawned on sustain pedal up
461          (CC #64) events.
462        - Fix: Release trigger voices can now also distinguish correctly between
463          note-off and sustain pedal up events.
464        - All engines: Increased ramp speed of volume smoother and pan smoother
465          (while slow rate of crossfade smoother is preserved) to allow quick
466          volume and pan changes by instrument scripts for instance.
467        - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
468          properly and thus were ignored for certain uses.
469        - Added new C++ API method
470          VirtualMidiDevice::SendChannelPressureToSampler().
471        - windows, 32-bit: fixed potential crashes by making sure the stack in
472          sub threads is 16-byte aligned
473        - fixed numerous compiler warnings
474        - Fixed invalid (note-on) event ID being assigned to new Note objects.
475        - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
476          fixes potential undefined behavior.
477        - Fixed Note object leak when triggering notes on keys which did not
478          have a valid sample mapped (fixes bug #252).
479        - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
480        - linuxsampler binary fix: option --create-instruments-db ignored
481          subsequent optional argument due to glibc's implementation oddity
482          which expects a "=" sign, but no space between them.
483    
484      * packaging changes:
485        - removed unnecessary dependency to libuuid
486          (originated by libgig's usage of it)
487        - Automake: set environment variable GCC_COLORS=auto to allow GCC to
488          auto detect whether it (sh/c)ould output its messages in color.
489        - Debian: Fixed packaging error about invalid "Source-Version"
490          substitution variable.
491        - Debian: Raised Debian compatibility level to Debian 9 "Stretch".
492        - Debian: Added build dependency to libsqlite3-dev for building
493          linuxsampler with instruments DB support.
494    
495      * Real-time instrument scripts:
496        - Implemented scheduler for delayed MIDI events and for suspended scripts.
497        - Built-in script function "wait()": implemented support for function's
498          "duration-us" argument, thus scripts using this function are now
499          correctly resumed after the requested amount of microseconds.
500        - Built-in script function "play_note()": implemented support for
501          function's "duration-us" argument, thus notes triggered with this
502          argument are now correctly released after the requested amount of
503          microseconds.
504        - Fix: script events were not cleared when engine channel was reset,
505          potentially causing undefined behavior.
506        - Fixed crash which happened when trying to reference an undeclared
507          variable.
508        - Built-in script function "play_note()": Added support for passing
509          special value -1 for "duration-us" argument, which will cause the
510          triggered note to be released once the original note was released.
511        - Instrument script classes now exported with the liblinuxsampler C++ API.
512        - Added new API method ScriptVM::syntaxHighlighting() which provides
513          a convenient syntax highlighting backend for external instrument
514          script editor applications.
515        - Added new C++ API class "ScriptVMFactory".
516        - Extended parser issues to provide not only first line and first
517          column, but also last line and last column of issue (thus marking
518          the precise span of the issue within the source code).
519        - Reload script automatically after being modified by an instrument
520          editor.
521        - NKSP language grammar correction: allow empty event handler bodies
522          like "on note end on".
523        - Implemented built-in script function "change_vol()".
524        - Implemented built-in script function "change_tune()".
525        - Implemented built-in script function "change_pan()".
526        - Implemented built-in script function "change_cutoff()".
527        - Implemented built-in script function "change_reso()".
528        - Implemented built-in script function "event_status()".
529        - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
530          "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
531          "event_status()" function.
532        - NKSP language: Added support for bitwise operators ".or.", ".and."
533          and ".not.".
534        - NKSP language scanner: Fixed IDs matching to require at least one
535          character (i.e. when matching function names or variable names).
536        - NKSP language scanner: disabled unusued rules.
537        - Fixed behavior of play_note() and note_off() functions which must
538          be distinguished engine internally from "real" MIDI note on/off
539          events in order to avoid misbehaviors like hanging notes.
540        - Implemented built-in script variable "$KSP_TIMER".
541        - Implemented built-in script variable "$NKSP_REAL_TIMER".
542        - Implemented built-in script variable "$NKSP_PERF_TIMER".
543        - Implemented built-in script variable "$ENGINE_UPTIME".
544        - Implemented built-in script function "inc()".
545        - Implemented built-in script function "dec()".
546        - NKSP language fix: division expressions were evaluated too often.
547        - NKSP language fix: string concatenation operator was right
548          associative instead of left (to right).
549        - NKSP language correction: allow empty statements in entire language
550          (i.e. "if end if").
551        - Implemented built-in script function "stop_wait()".
552        - Implemented built-in script variable "$NI_CALLBACK_ID".
553        - Implemented built-in script variable "$NI_CALLBACK_TYPE".
554        - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
555        - Added support for read-only built-in variables (respectively
556          handled by the script parser).
557        - Added built-in script constant "$NI_CB_TYPE_INIT".
558        - Added built-in script constant "$NI_CB_TYPE_NOTE".
559        - Added built-in script constant "$NI_CB_TYPE_RELEASE".

563        - Implemented built-in script function "change_decay()".
564        - Implemented built-in script function "change_release()".
565        - Fixed all change_*() built-in script functions to apply their
566          synthesis parameter changes immediately in case the respective note
567          was triggered at the same time, instead of scheduling the parameter
568          change, especially because it would cause some parameter types's
569          changes either to be ramped (i.e. change_vol()) or other types even
570          to have not effect at all (i.e. change_attack()).
571        - Implemented built-in script function "sh_left()".
572        - Implemented built-in script function "sh_right()".
573        - Implemented built-in script function "min()".
574        - Implemented built-in script function "max()".
575        - NKSP Fix: "init" event handler was not always executed when a script
576          was loaded.
577        - NKSP built-in wait() script function: abort script execution if
578          a negative or zero wait time was passed as argument (since this is
579          a common indication of a bug either of the script or even of the
580          engine, which could lead to RT instability or even worse).
581        - ScriptVM: Implemented automatic suspension of RT safety
582          threatening scripts.
583        - Provide more user friendly error messages on syntax errors.
584        - Fixed NKSP parser warning "Not a statement" when assigning an
585          initializer list to an array variable.
586        - Implemented built-in script array variable "%ALL_EVENTS".
587        - Implemented built-in script function "in_range()".
588        - Implemented built-in script function "change_amp_lfo_depth()".
589        - Implemented built-in script function "change_amp_lfo_freq()".

593        - Implemented built-in script function "change_tune_time()".
594        - Implemented built-in script function "fade_in()".
595        - Implemented built-in script function "fade_out()".
596        - Fixed acceptance of wrong data type of parameters passed to built-in
597          script functions "change_vol()", "change_tune()", "change_pan()",
598          "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
599          "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
600          "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
601        - Added built-in script function "get_event_par()" and implemented some
602          of its possible parameter selections.
603        - Added built-in script function "set_event_par()" and implemented some
604          of its possible parameter selections.
605        - Fixed a bunch of scheduler time related bugs.
606        - Fixed polyphonic variables not being reset to zero after usage.
607        - Built-in "ignore_event()" function: argument is now optional, like with
608          built-in function "ignore_controller()".
609        - Implemented built-in script function "change_velo()".
610        - Implemented built-in script function "change_note()".
611        - Adjusted behavior of "change_vol()" and "change_tune()" to a more
612          intuitive behavior if used in combination with "change_vol_time()" or
613          "change_tune_time()" respectively: now tuning/volume changes are only
614          assigned (without delay) immediately to a new note if the respective
615          timing function has not been called before, otherwise the volume/tuning
616          changes are automatically faded (before, only the event's time stamp was
617          relevant).
618         - Implemented built-in script function "array_equal()".
619         - Implemented built-in script function "search()".
620         - Implemented built-in script function "sort()".
621         - NKSP Fix: Never suspend "init" event handlers.
622         - Implemented built-in script function "same_region()" (currently only
623           available for gig format engine).
624         - Added built-in script constant "$NKSP_LINEAR".
625         - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
626         - Implemented built-in script function "change_vol_curve()".
627         - Implemented built-in script function "change_tune_curve()".
628         - built-in "play_note()" function now supports a sample playback start
629           offset with argument 3, where special value -1 means to use the regular
630           sample offset as defined by the instrument file.
631         - Built-in array variable %KEY_DOWN[] is now a read-only variable.
632         - Built-in variable $EVENT_NOTE is now a read-only variable.
633         - Built-in variable $EVENT_VELOCITY is now a read-only variable.
634         - built-in "play_note()" function now accepts -2 for its fourth argument
635           (note duration) which means the life time of the note shall be sticked
636           to the requested note number of argument 1.
637         - Fix: built-in "play_note()" function now returns 0 as result value if
638           -1 was passed for its fourth argument (note duration) and the respective
639           parent note is already gone.
640        - Implemented built-in script function "change_play_pos()".
641        - NKSP language: Added support for user declared const array variables.
642        - NKSP language: Raise parser warning if array variable is accessed with
643          an index that exceeds the array's size.
644        - NKSP language fix: Unknown characters were not handled correctly.
645        - NKSP language: Added support for "synchronized .. end synchronized"
646          code blocks.
647        - Implemented built-in script function "abort()" which allows to abort
648          another script handler by passing its callback ID.
649        - Fixed potential memory access bug and potential undefined behavior of
650          "init" event handlers.
651        - Print a time stamp along to each call of built-in function "message()".
652        - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
653          to retrieve all code blocks filtered out by the preprocessor.
654        - Added built-in script function "fork()".
655        - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
656        - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
657        - Fixed potential crash when accessing dynamic built-in array variables.
658        - Added built-in script function "callback_status()".

662        - Removed max. value limitation of built-in functions "change_attack()",
663          "change_decay()" and "change_release()" to i.e. allow passing 2000000
664          for doubling the respective time.
665        - NKSP script editor syntax highlighting API: Fixed app termination due
666          to a lexer start condition stack underrun.
667        - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
668          USE_CODE_IF_NOT() preprocessor statements.
669        - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
670          can be set to disable all subsequent built-in "message()" function calls
671          on preprocessor level.
672        - Implemented built-in script function "change_sustain()".
673        - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
674          to avoid the editor app to crash on ill-formed text input.
675        - Added built-in script function "change_pan_time()".
676        - Added built-in script function "change_pan_curve()".

685        - Fixed memory access bug of general DB access code which lead to
686          undefined behavior.
687        - Cleanup of instruments DB file creation and opening code.
688        - The instrument DB path of linuxsampler's --create-instruments-db argument
689          is now optional, if it is missing, then a default location is used.
690        - Added support for scanning SFZ (.sfz) files.
691        - Added support for scanning Sound Font (.sf2) files.
692        - Fixed undefined DB transaction behavior.

756      - implemented sine LFO, pulse LFO and saw LFO      - implemented sine LFO, pulse LFO and saw LFO
757        - experimental support for per voice equalization
758        - added command line option --exec-after-init
759        - Introduced new C++ API method:
760          EngineChannel::InstrumentFileName(int index)
761          allowing to retrieve the whole list of files used for the loaded
762          instrument on an engine channel (a.k.a. part). Some GigaStudio
763          instruments for example are splitted over several files like
764          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
765        - Added new C++ API method Sampler::GetGlobalMaxVoices().
766        - Added new C++ API method Sampler::GetGlobalMaxStreams().
767        - Added new C++ API method Sampler::SetGlobalMaxVoices().
768        - Added new C++ API method Sampler::SetGlobalMaxStreams().
769        - Various "const" and "restrict" optimizations.
770        - all engines: add pan CC value to instrument pan parameter before
771          applying panning, instead of using two separate pan functions in
772          series (#182)
773        - added a lock guard class for exception safe mutex handling and
774          used it everywhere appropriate
775        - Immediately apply scale tuning changes to active voices.
776        - Exposed scale tuning to C++ API (along to the already existing standard
777          SysEx way).
778        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
779          and broken for ppc64. (Seq_cst loads and stores are actually not
780          used in LS, so the bug wasn't noticable.)
781        - lsatomic.h: added ARMv7 support
782        - Added support for multiple MIDI input ports per sampler channel (and
783          added various new C++ methods for this new feature / design change, old
784          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
785          as deprecated but are still there and should provide full behavior
786          backward compatibility).
787        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
788          unsafe and caused compilation error with clang 2.x).
789        - Bugfix: only process the latest MIDI program change event.
790        - Introducing the LSCP shell, which provides convenient control of the
791          sampler from the command line by providing LSCP aware features.
792        - VirtualMidiDevice: Added support for program change.
793        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
794        - VirtualMidiDevice: Added support for pitch bend.
795        - Aftertouch: extended API to explicitly handle channel pressure and
796          polyphonic key pressure events (so far polyphonic pressure was not
797          supported at all, and channel pressure was rerouted as CC128 but not
798          used so far).
799        - Added initial support for real-time instrument scripts. The script VM
800          code is shared by all sampler engine implemementations, however only the
801          gig file format currently provides support for storing instrument scripts
802          (as LinuxSampler extension to the original GigaStudio 4 format).

814        - handle special case when pan parameter in gig file has max or
815          min value
816        - Exclusive Groups: don't ever stop voices of the same note,
817          doesn't sound naturally with a drumkit
818        - fixed EG1 modulation when attack or release is zero
819        - Fixed support for 'aftertouch' attenuation controller.

1201        - When creating MIDI instrument map entries with "PERSISTENT" type, the
1202          instruments were uselessly precached with zero samples, however it still
1203          took the full preloading time and on 1st program change the respective
1204          instrument was completely reloaded again.
1205        - fixed handling of rapid bank select and program change messages
1206          sent to the same sampler channel (patch from the Open Octave

1223        - fixed erroneous error message piping in VoiceBase.h
1224          (labelled "Disk stream not available in time")
1225        - Update effects on sample rate & period size changes (to avoid
1226          crashes and noise on such transitions).
1227        - ignore missing LADSPA paths without ignoring valid LADSPA paths
1228          (fixes #208)
1229        - Fixed bug in LSCP grammar definition which caused a statement like
1230          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1231          practically irrelevant, however it caused problems with the new LSCP
1232          shell's auto completion feature).
1233        - Fixed MIDI program change messages being ignored if quickly executed
1234          after each other (fixes #231).
