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

471        - Implemented built-in script function "change_reso()".
472        - Implemented built-in script function "event_status()".
473        - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
474          "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
475          "event_status()" function.
476        - NKSP language: Added support for bitwise operators ".or.", ".and."
477          and ".not.".
478        - NKSP language scanner: Fixed IDs matching to require at least one
479          character (i.e. when matching function names or variable names).
480        - NKSP language scanner: disabled unusued rules.
481        - Fixed behavior of play_note() and note_off() functions which must
482          be distinguished engine internally from "real" MIDI note on/off
483          events in order to avoid misbehaviors like hanging notes.
484        - Implemented built-in script variable "$KSP_TIMER".
485        - Implemented built-in script variable "$NKSP_REAL_TIMER".
486        - Implemented built-in script variable "$NKSP_PERF_TIMER".
487        - Implemented built-in script variable "$ENGINE_UPTIME".
488        - Implemented built-in script function "inc()".
489        - Implemented built-in script function "dec()".
490        - NKSP language fix: division expressions were evaluated too often.
491        - NKSP language fix: string concatenation operator was right
492          associative instead of left (to right).
493        - NKSP language correction: allow empty statements in entire language
494          (i.e. "if end if").
495        - Implemented built-in script function "stop_wait()".
496        - Implemented built-in script variable "$NI_CALLBACK_ID".
497        - Implemented built-in script variable "$NI_CALLBACK_TYPE".
498        - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
499        - Added support for read-only built-in variables (respectively
500          handled by the script parser).
501        - Added built-in script constant "$NI_CB_TYPE_INIT".
502        - Added built-in script constant "$NI_CB_TYPE_NOTE".
503        - Added built-in script constant "$NI_CB_TYPE_RELEASE".

507        - Implemented built-in script function "change_decay()".
508        - Implemented built-in script function "change_release()".
509        - Fixed all change_*() built-in script functions to apply their
510          synthesis parameter changes immediately in case the respective note
511          was triggered at the same time, instead of scheduling the parameter
512          change, especially because it would cause some parameter types's
513          changes either to be ramped (i.e. change_vol()) or other types even
514          to have not effect at all (i.e. change_attack()).
515        - Implemented built-in script function "sh_left()".
516        - Implemented built-in script function "sh_right()".
517        - Implemented built-in script function "min()".
518        - Implemented built-in script function "max()".
519        - NKSP Fix: "init" event handler was not always executed when a script
520          was loaded.
521        - NKSP built-in wait() script function: abort script execution if
522          a negative or zero wait time was passed as argument (since this is
523          a common indication of a bug either of the script or even of the
524          engine, which could lead to RT instability or even worse).
525        - ScriptVM: Implemented automatic suspension of RT safety
526          threatening scripts.
527        - Provide more user friendly error messages on syntax errors.
528        - Fixed NKSP parser warning "Not a statement" when assigning an
529          initializer list to an array variable.
530        - Implemented built-in script array variable "%ALL_EVENTS".
531        - Implemented built-in script function "in_range()".
532        - Implemented built-in script function "change_amp_lfo_depth()".
533        - Implemented built-in script function "change_amp_lfo_freq()".
534        - Implemented built-in script function "change_pitch_lfo_depth()".
535        - Implemented built-in script function "change_pitch_lfo_freq()".
536        - Implemented built-in script function "change_vol_time()".
537        - Implemented built-in script function "change_tune_time()".
538        - Implemented built-in script function "fade_in()".
539        - Implemented built-in script function "fade_out()".
540        - Fixed acceptance of wrong data type of parameters passed to built-in
541          script functions "change_vol()", "change_tune()", "change_pan()",
542          "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
543          "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
544          "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
545        - Added built-in script function "get_event_par()" and implemented some
546          of its possible parameter selections.
547        - Added built-in script function "set_event_par()" and implemented some
548          of its possible parameter selections.
549        - Fixed a bunch of scheduler time related bugs.
550        - Fixed polyphonic variables not being reset to zero after usage.
551        - Built-in "ignore_event()" function: argument is now optional, like with
552          built-in function "ignore_controller()".
553        - Implemented built-in script function "change_velo()".
554        - Implemented built-in script function "change_note()".
555        - Adjusted behavior of "change_vol()" and "change_tune()" to a more
556          intuitive behavior if used in combination with "change_vol_time()" or
557          "change_tune_time()" respectively: now tuning/volume changes are only
558          assigned (without delay) immediately to a new note if the respective
559          timing function has not been called before, otherwise the volume/tuning
560          changes are automatically faded (before, only the event's time stamp was
561          relevant).
562         - Implemented built-in script function "array_equal()".
563         - Implemented built-in script function "search()".
564         - Implemented built-in script function "sort()".
565         - NKSP Fix: Never suspend "init" event handlers.
566         - Implemented built-in script function "same_region()" (currently only
567           available for gig format engine).
568         - Added built-in script constant "$NKSP_LINEAR".
569         - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
570         - Implemented built-in script function "change_vol_curve()".
571         - Implemented built-in script function "change_tune_curve()".
572         - built-in "play_note()" function now supports a sample playback start
573           offset with argument 3, where special value -1 means to use the regular
574           sample offset as defined by the instrument file.
575         - Built-in array variable %KEY_DOWN[] is now a read-only variable.
576         - Built-in variable $EVENT_NOTE is now a read-only variable.
577         - Built-in variable $EVENT_VELOCITY is now a read-only variable.
578         - built-in "play_note()" function now accepts -2 for its fourth argument
579           (note duration) which means the life time of the note shall be sticked
580           to the requested note number of argument 1.
581         - Fix: built-in "play_note()" function now returns 0 as result value if
582           -1 was passed for its fourth argument (note duration) and the respective
583           parent note is already gone.
584        - Implemented built-in script function "change_play_pos()".
585        - NKSP language: Added support for user declared const array variables.
586        - NKSP language: Raise parser warning if array variable is accessed with
587          an index that exceeds the array's size.
588        - NKSP language fix: Unknown characters were not handled correctly.
589        - NKSP language: Added support for "synchronized .. end synchronized"
590          code blocks.
591        - Implemented built-in script function "abort()" which allows to abort
592          another script handler by passing its callback ID.
593        - Fixed potential memory access bug and potential undefined behavior of
594          "init" event handlers.
595        - Print a time stamp along to each call of built-in function "message()".
596        - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
597          to retrieve all code blocks filtered out by the preprocessor.
598        - Added built-in script function "fork()".
599        - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
600        - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
601        - Fixed potential crash when accessing dynamic built-in array variables.

606        - Removed max. value limitation of built-in functions "change_attack()",
607          "change_decay()" and "change_release()" to i.e. allow passing 2000000
608          for doubling the respective time.
609        - NKSP script editor syntax highlighting API: Fixed app termination due
610          to a lexer start condition stack underrun.
611        - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
612          USE_CODE_IF_NOT() preprocessor statements.
613        - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
614          can be set to disable all subsequent built-in "message()" function calls
615          on preprocessor level.
616        - Implemented built-in script function "change_sustain()".
617        - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
618          to avoid the editor app to crash on ill-formed text input.
619        - Added built-in script function "change_pan_time()".
620        - Added built-in script function "change_pan_curve()".

626        - Added built-in script function "change_cutoff_lfo_freq()".
627    
628      * Instruments DB:
629        - Fixed memory access bug of general DB access code which lead to
630          undefined behavior.
631        - Cleanup of instruments DB file creation and opening code.
632        - The instrument DB path of linuxsampler's --create-instruments-db argument
633          is now optional, if it is missing, then a default location is used.
634        - Added support for scanning SFZ (.sfz) files.
635        - Added support for scanning Sound Font (.sf2) files.
636        - Fixed undefined DB transaction behavior.
637    
638    Version 2.0.0 (15 July 2015)

645          doing "make dist"
646        - removed empty directories left from the cvs to svn migration
647        - fixed compilation with gcc 4.6.1
648        - another "make dist" fix, for the LV2 plugin
649        - made --enable-pthread-testcancel default on Mac OS X
650        - minor Makefile fix for building lscpparser when build and source
651          directories are separate

672        - support building with older jack versions
673        - support building with spaces in vst sdk path
674        - enabled automake 'subdir-objects' option and moved external
675          source references (vst, au, asio) from makefiles to cpp files,
676          in order to get rid of warnings from automake 1.14
677    
678      * general changes:
679        - Refactoring: moved the independent code from
680          the Gigasampler format engine to base classes
681        - command line option '--profile' is currently disabled, since the
682          respective profiling code is currently broken
683        - Introduced support for optional environment variable
684          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
685          where the sampler shall look for instrument editor plugins
686          (patch by Luis Garrido, slightly modified).
687        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
688        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
689        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
690          note (in this implementation of the sampler its simply hard routed to
691          the 1st effect send of the sampler channel, no matter what the actual
692          effect type is)
693        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
694          note (in this implementation of the sampler its simply hard routed to
695          the 2nd effect send of the sampler channel, no matter what the actual
696          effect type is)
697        - implemented support for internal LADSPA effects
698        - raised limit of program change queue from 100 to 512
699          (as suggested by Alex Stone)
700        - implemented sine LFO, pulse LFO and saw LFO
701        - experimental support for per voice equalization
702        - added command line option --exec-after-init
703        - Introduced new C++ API method:
704          EngineChannel::InstrumentFileName(int index)
705          allowing to retrieve the whole list of files used for the loaded
706          instrument on an engine channel (a.k.a. part). Some GigaStudio
707          instruments for example are splitted over several files like
708          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
709        - Added new C++ API method Sampler::GetGlobalMaxVoices().
710        - Added new C++ API method Sampler::GetGlobalMaxStreams().
711        - Added new C++ API method Sampler::SetGlobalMaxVoices().
712        - Added new C++ API method Sampler::SetGlobalMaxStreams().
713        - Various "const" and "restrict" optimizations.
714        - all engines: add pan CC value to instrument pan parameter before
715          applying panning, instead of using two separate pan functions in
716          series (#182)
717        - added a lock guard class for exception safe mutex handling and
718          used it everywhere appropriate
719        - Immediately apply scale tuning changes to active voices.
720        - Exposed scale tuning to C++ API (along to the already existing standard
721          SysEx way).
722        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
723          and broken for ppc64. (Seq_cst loads and stores are actually not
724          used in LS, so the bug wasn't noticable.)
725        - lsatomic.h: added ARMv7 support
726        - Added support for multiple MIDI input ports per sampler channel (and
727          added various new C++ methods for this new feature / design change, old
728          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
729          as deprecated but are still there and should provide full behavior
730          backward compatibility).
731        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
732          unsafe and caused compilation error with clang 2.x).
733        - Bugfix: only process the latest MIDI program change event.
734        - Introducing the LSCP shell, which provides convenient control of the
735          sampler from the command line by providing LSCP aware features.
736        - VirtualMidiDevice: Added support for program change.
737        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
738        - VirtualMidiDevice: Added support for pitch bend.
739        - Aftertouch: extended API to explicitly handle channel pressure and
740          polyphonic key pressure events (so far polyphonic pressure was not
741          supported at all, and channel pressure was rerouted as CC128 but not
742          used so far).
743        - Added initial support for real-time instrument scripts. The script VM
744          code is shared by all sampler engine implemementations, however only the
745          gig file format currently provides support for storing instrument scripts
746          (as LinuxSampler extension to the original GigaStudio 4 format).
747

758        - handle special case when pan parameter in gig file has max or
759          min value
760        - Exclusive Groups: don't ever stop voices of the same note,
761          doesn't sound naturally with a drumkit

944        - Listen to all interfaces on Mac OS X (INADDR_ANY)
945        - VST bugfix: If the host called resume() before and after
946          changing sample rate or block size, the number of channels was
947          incorrectly set to two. This caused silence in Cubase 5.
948        - save engine type (gig, sfz or sf2) in plugin state
949        - VST: when opening Fantasia, look for both 32 and 64 bit Java on
950          64 bit Windows
951        - AU: changed number of output channels from one stereo to 16
952          stereo

965          Linux, the Fantasia jar should be placed in <prefix>/share/java)
966        - VST: fixed crashes on Linux Ardour and EnergyXT
967        - DSSI bugfix: it wasn't possible to change engine type. The MIDI

986        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
987          the ALSA sequencer client name

989          there is no reason for this limit
990        - MME: fixed memory handling bug found with cppcheck
991        - MME: removed compiler warning
992        - CoreMIDI: implemented driver specific port parameter "CORE_MIDI_BINDINGS",
993          which allows to retrieve the list of CoreMIDI clients / ports and to connect
994          to them a la JACK, via the usual sampler APIs
995        - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
996          the driver will automatically connect to other CoreMIDI clients' ports

1004        - CoreMIDI fix: a MIDIPacket can contain more than one event per packet.
1005        - MME bugfix: driver wasn't closed properly
1006        - CoreMIDI: automatically connect to all input sources by default (driver
1007          parameter "AUTO_BIND").
1008        - CoreMIDI: fixed auto bind feature to CoreMIDI ports that go online
1009        - CoreMIDI: fixed minor memory leak
1010    
1011      * audio driver:
1012        - ASIO driver fixes for newer gcc versions (fix from PortAudio)
1013        - JACK audio: react on sample rate changes.

1016          RT context.
1017        - ASIO driver: removed compiler warnings
1018        - CoreAudio: fixed minor error handling bug
1019        - ASIO driver: be more verbose when no ASIO card could be found (fixes #203)

1021          for audio device parameter "SAMPLERATE" (fixes #166).
1022    
1023      * LSCP server:
1024        - added support for sending MIDI CC messages via LSCP command

1131          channel to a different engine type
1132        - fixed crash when deleting a sampler channel or changing engine
1133          type while an instrument load was in progress
1134        - bugfix: playing a note while changing the instrument could cause
1135          a crash, or give "Handing back unknown region" error messages
1136        - bugfix: calling SET VOICES (which Fantasia does on start and
1137          refresh) could cause instruments to be unloaded
1138        - Mac OS X: fixed name collision of enum in EffectControl and
1139          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
1140        - Mac OS X: fixed hanging threads
1141        - Windows: disabled the previous thread fix on non-Mac systems, as
1142          it caused hanging threads on Windows
1143        - Fixed possible crashes due to corrupted MIDI/audio device list
1144          after MIDI/audio device creation failure
1145        - When creating MIDI instrument map entries with "PERSISTENT" type, the
1146          instruments were uselessly precached with zero samples, however it still
1147          took the full preloading time and on 1st program change the respective
1148          instrument was completely reloaded again.
1149        - fixed handling of rapid bank select and program change messages
1150          sent to the same sampler channel (patch from the Open Octave
1151          project, slightly adjusted)
1152        - fixed crash when trying to create an effect instance with controls
1153          which min and/or max values depend on the sample rate

1161        - sfz/sf2 engine: fixed crash when using small audio fragment size
1162        - Mac OS X: fixed crash when unloading plugin on 10.7 and later
1163        - Mac OS X: fixed process hang when unloading 32-bit plugin (bug
1164          introduced in previous fix)
1165        - fixed crash when a channel received a program change while
1166          playing a note in a key group
1167        - fixed erroneous error message piping in VoiceBase.h
1168          (labelled "Disk stream not available in time")
1169        - Update effects on sample rate & period size changes (to avoid
1170          crashes and noise on such transitions).
1171        - ignore missing LADSPA paths without ignoring valid LADSPA paths
1172          (fixes #208)
1173        - Fixed bug in LSCP grammar definition which caused a statement like
1174          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1175          practically irrelevant, however it caused problems with the new LSCP
1176          shell's auto completion feature).
1177        - Fixed MIDI program change messages being ignored if quickly executed
1178          after each other (fixes #231).
