3    * general changes:    * general changes:
4        - AbstractEngineChannel: fixed CCs not being forwarded to all
5          VirtualMIDIDevices.
6    
7      * Real-time instrument scripts:
8        - Fix: Do not share compiled instrument scripts among multiple engine
9          channels (sampler parts) as this can lead to crashes and would allow the
10          same global script variables to be accessible from multiple engine
11          channels which would not be the expected behaviour by instrument script
12          authors.
13    
14      * GigaStudio/Gigasampler format engine:
15        - Use libgig's new IO-per-thread feature to avoid file I/O concurrency
16          issues with .gig file.
17        - Use libgig's new method gig::File::GetSample() with method
18          gig::File::CountSamples() instead of now deprecated
19          gig::File::GetFirstSample() / gig::File::GetNextSample() pair.
20        - Use libgig's new method gig::Instrument::GetRegionAt() with method
21          gig::Instrument:CountRegions() instead of now deprecated
22          gig::Instrument::GetFirstRegion() / gig::Instrument::GetNextRegion() pair.
23        - Use libgig's gig::File::GetInstrument() method with method
24          gig::File::CountInstruments() instead of now deprecated
25          gig::File::GetFirstInstrument() / gig::File::GetNextInstrument() pair.
26    
27      * MIDI driver:
28        - VirtualMidiDevice: added method Reset() which is e.g. intended to be used
29          in "panic" / MIDI "all sound off" / MIDI "all note off" situations.
30        - VirtualMidiDevice: release all notes on MIDI CC #120 and CC #123.
31    
32    Version 2.2.0 (9 May 2021)
33    
34      * general changes:
35      - Fixed compiler error in Pool.h.      - Fixed compiler error in Pool.h.
36      - Require C++14 compiler support.      - Require C++14 compiler support.
37      - Autoconf: Added m4/ax_cxx_compile_stdcxx.m4 macro which is used      - Autoconf: Added m4/ax_cxx_compile_stdcxx.m4 macro which is used
# Line 10  Version SVN trunk (?) Line 41  Version SVN trunk (?)
41      - RTMath: Implemented floating point comparison methods      - RTMath: Implemented floating point comparison methods
42        fEqual32(float,float) and fEqual64(double,double) which take the        fEqual32(float,float) and fEqual64(double,double) which take the
43        expected floating point tolerances into account.        expected floating point tolerances into account.
44        - Added public API C++ class "LFO", which is a cluster class encapsulating
45          all the sampler's LFO implementations to be used by 3rd party applications
46          (e.g. by Gigedit).
47        - Added int math square LFO implementation.
48        - Added int math saw LFO implementation.
49        - Added numeric complex nr sine LFO implementation.
50        - Marked class LFOTriangleDiHarmonic as deprecated
51          (will be removed in future).
52        - Added LFOAll.h which includes all LFO implementation's header files.
53        - Refactored LFO class names and their file names (PulseLFO -> LFOPulse,
54          LFOSawIntMath -> LFOSawIntMathNew, SawLFO -> LFOSawIntMathOld,
55          SineLFO -> LFOSineBuiltinFn, LFOSine -> LFOSineNumericComplexNr,
56          SquareLFO -> LFOSquarePulse and separated the latter to its own header
57          file).
58        - Renamed type LFOSigned -> LFOTriangleSigned.
59        - Renamed type LFOUnsigned -> LFOTriangleUnsigned.
60        - Using now cubic interpolation as resampling algorithm by default; and
61          linear interpolation is deprecated now.
62        - Event:Init(): memset() entire Event::Param union to zero instead of trying
63          to do that for its individual members; the latter became error prone due
64          to the union's growing complexity meanwhile.
65        - EngineChannel: Overhaul of RPN/NRPN related methods: Added new
66          *Rpn*Parameter*() methods as replacement for previous *Rpn*Controller*()
67          methods and marked the old ones as deprecated; and likewise added new
68          *Nrpn*Parameter*() methods as replacement for previous *Nrpn*Controller*()
69          methods and marked those old ones deprecated as well.
70        - Added support for MIDI CC #38 (data entry LSB): this allows higher value
71          resolution for certain (e.g. hard coded) RPN and NRPN parameters.
72        - Implemented support for compressed RPN/NRPN message sequences (that is to
73          allow processing MIDI data entry messages without always having to be
74          preceded strictly by RPN/NRPN parameter selection messages on each value
75          change).
76        - Added support for MIDI CC #96 (data increment) and MIDI CC #97 (data
77          decrement).
78        - Added support for 'null function RPN/NRPN' (which is RPN/NRPN parameter
79          MSB=127 and LSB=127) and which is disabling subsequent data
80          entry/increment/decrement CC messages.
81        - Fixed crash when editing key groups (a.k.a. exclusive groups) with an
82          instrument editor.
83        - Fixed playing noise at the end of a disk stream under certain conditions.
84        - Fixed potential crash with high pitch at end of RAM playback.
85        - Added configure checks whether C++ compiler supports so called
86          'designated initializers'.
87        - Added global backtraceAsString() function for debugging purposes
88          (POSIX systems only, no Windows implementation yet).
89        - Thread class: Added new methods pushCancelable(), popCancelable(), name(),
90          nameOfCaller() and setNameOfCaller().
91        - configure: Always check for availability of pthread_testcancel() and use
92          it if so (previously it was only used if explicitly enabled by configure
93          option).
94        - Thread class: raise compiler warning if pthread_testcancel() is not
95          available, because it can lead to deadlocks.
96        - Mutex class: Implemented optional bug detection and deadlock debugging
97          features.
98        - Ref<> class is now thread safe (as lock-free and wait-free
99          implementation).
100        - Fixed compilation error with Bison >= 3.6.0.
101        - Fixed rare crash when switching between instruments that had instrument
102          scripts loaded.
103        - Allow EffectChain::InsertEffect() as alternative to
104          EffectChain::AppendEffect() (i.e. with index equal to current chain size).
105        - ConstCapacityArray class: Fixed bug in remove() method.
106        - Fixed crash on certain MIDI RPN and NRPN messages that occurred if no
107          real-time instrument script was loaded.
108    
109    * Real-time instrument scripts:    * Real-time instrument scripts:
110      - Added method ScriptVM::setExitResultEnabled() which allows to      - Added method ScriptVM::setExitResultEnabled() which allows to

245        "change_pan_time()", "fade_in()", "fade_out()", "change_play_pos()".        "change_pan_time()", "fade_in()", "fade_out()", "change_play_pos()".
246      - Fixed built-in function "change_play_pos()" not having accepted metric      - Fixed built-in function "change_play_pos()" not having accepted metric
247        prefixes at all.        prefixes at all.
248        - Fixed the following built-in functions having misinterpreted values given
249          with unit type (for their 2nd argument) as if they were relative values
250          (that is as if they were passed without a unit type): "change_attack()",
251          "change_decay()", "change_release()", "change_cutoff_attack()",
252          "change_cutoff_decay()", "change_cutoff_release()".
253        - Fixed the following built-in functions having applied completely wrong
254          'final' values: "change_sustain()", "change_cutoff_sustain()" (since the
255          respective EGs being their modulation sink assume uint data type with
256          value range 0..1000 instead of 0.0..1.0.
257        - Added individual parse-time checks of function arguments for the following
258          built-in functions: "play_note()", "note_off()", "set_event_mark()",
259          "delete_event_mark()", "by_marks()", "change_cutoff()", "change_attack()",
260          "change_decay()", "change_release()", "change_cutoff_attack()",
261          "change_cutoff_decay()", "change_cutoff_release()",
262          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
263          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()" and
264          "change_pan_time()".
265        - Don't abort function call if unit type was used and at the same time
266          'final' operator was omitted for the primary value argument of the
267          following built-in functions: "change_cutoff()", "change_attack()",
268          "change_decay()", "change_release()", "change_cutoff_attack()",
269          "change_cutoff_decay()", "change_cutoff_release()",
270          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
271          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
272          "change_pan_time()", instead imply 'final'ness at runtime and raise an
273          appropriate parser warning at parse time.
274        - Added built-in real number functions "round()", "ceil()", "floor()",
275          "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()", "sin()",
276          "cos()", "tan()", "asin()", "acos()", "atan()".
277        - Added built-in script real number constant "~NI_MATH_PI".
278        - Added built-in script real number constant "~NI_MATH_E".
279        - NKSP language: Allow unary '+' operator.
280        - Added built-in script functions "msb()" and "lsb()".
281        - NKSP language: Added support for RPN event handler
282          ("on rpn ... end on" in instrument scripts).
283        - NKSP language: Added support for NRPN event handler
284          ("on nrpn ... end on" in instrument scripts).
285        - Added built-in read-only variables "$RPN_ADDRESS" and "$RPN_VALUE" which
286          may be read from the new RPN/NRPN script handlers to get the (N)RPN
287          parameter that had been changed and its new value.
288        - Added built-in const variables "$NI_CB_TYPE_RPN" and "$NI_CB_TYPE_NRPN"
289          which are identifying the new (N)RPN handlers as such at script runtime.
290        - Implemented built-in script function "set_rpn()".
291        - Implemented built-in script function "set_nrpn()".
292        - Fix: built-in functions returning an array type were broken and caused a
293          crash when the built-in function's (supposed to be array) result value was
294          used by the script VM.
295        - Removed upper value constraint for 2nd argument of built-in functions
296          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
297          "change_pitch_lfo_freq()","change_reso()", "change_cutoff()",
298          "change_amp_lfo_depth()", "change_cutoff_lfo_depth()" and
299          "change_pitch_lfo_depth()", to allow e.g. passing value 2000000 to double
300          the LFO frequency / resonance / cutoff frequency.
301        - Reduced code involved for parsing NKSP variable declarations by using 2
302          generalized grammar rules with optional components (i.e. optional value
303          assignment and optional variable qualifiers) instead of previous linear
304          combinations of grammar rules, which also fixes some edge case.
305        - NKSP language parser: track code block locations also by a) raw byte
306          position in NKSP source code string and b) length of that code block in
307          bytes (along to the already existing code block tracking by line/column);
308          and added appropriate new members to public C++ API classes like
309          'firstByte' and 'lengthBytes' to class VMSourceToken and struct CodeBlock.
310        - NKSP language: Added support for 'patch' variable qualifier (capture their
311          locations and allow replacement of their assignment expression via VM C++
312          API).
313        - Fixed incorrect EG times if standard measuring unit was passed to built-in
314          functions "change_attack()", "change_decay()" or "change_release()".
315        - Fixed intermediate function result values never having reflected any
316          standard measuring unit type.
317        - Fixed re-entrant issue with function calls which caused wrong result
318          values if the same function was called multiple times in a term
319          (specifically if metric prefixes were used).
320        - NKSP language: Just throw a warning, not an error if an array variable of
321          size zero was declared.
322        - NKSP language: Allow omitting explicit array size on array variable
323          declaration if combined with immediate value assignment
324          (e.g. declare %foo[] := ( 1, 2, 3 ) ).
325        - NKSP language: emit warning if an array variable was declared with bigger
326          array size than amount of initial values been assigned, and initialize the
327          missing array elements with zero in this case.
328        - Fixed built-in NKSP exit() function to behave as return statement.
329        - NKSP parser: Fixed crash if unary '-' operator was used on a non-number
330          data type.
331        - NKSP VM: Fixed the "release" handler being executed too often under
332          certain situations if polyphonic data was passed from "note" handler to
333          "release" handler.
334        - Fixed memory leak in NKSP parser: string tokens were allocated as C
335          strings and never freed.
336        - Fixed incorrect polyphonic data transfer from wrong note handler to
337          release handler; which also fixes no release handler being executed
338          sometimes, and due to the latter it also fixes potential crashes as some
339          polyphonic script events were never released and the engine hence was
340          running out of free script events.
341        - Fixed crash when handling array results of built-in functions
342          (e.g. "num_elements(by_marks($MARK_1)").
343        - NKSP VM: Fixed dead note events not been removed from user's event groups
344          (i.e. causing incorrect behaviour of built-in NKSP functions by_marks()
345          and set_event_mark() after max. size of event group list was exhausted).
346    
347    * test cases:    * test cases:
348      - Fixed compiler errors in test cases.      - Fixed compiler errors in test cases.

363        equalness / unequalness comparison.        equalness / unequalness comparison.
364      - Added NKSP int array and real array tests for value assignment and      - Added NKSP int array and real array tests for value assignment and
365        initialization of arrays.        initialization of arrays.
366        - Added NKSP test cases for built-in functions "round()", "ceil()",
367          "floor()", "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()",
368          "sin()", "cos()", "tan()", "asin()", "acos()", "atan()".
369        - Added NKSP test cases for unary '+' operator.
370        - Added NKSP test cases for core built-in variables.
371        - Added thorough NKSP test cases for variable declarations.
372    
373      * GigaStudio/Gigasampler format engine:
374        - LFOTriangleIntMath and LFOTriangleIntAbsMath: Fixed FlipPhase=true
375          behaviour for start_level_mid.
376        - Changed LFO start levels: LFO1 and LFO2 both to mid, LFO3 to max. start
377          level (see discussion "GigaStudio LFO compatibility" on mailing list
378          from 2019-09-26 for details).
379        - Changed default wave form for all 3 LFOs to sine (instead of triangle;
380          see discussion "GigaStudio LFO compatibility" on mailing list from
381          2019-09-26 for details).
382        - Format extension: Added support for different LFO wave forms (currently
383          either sine [default], triangle, saw or square).
384        - Format extension: Added support for LFO phase displacement (0°..360°).
385        - Format extension: Added support for flipping LFO polarity on LFO 3
386          (in the original gig format this was only available for LFO 1 and LFO 2).
387        - Format extension: Support for additional filter types:
388          lowpass 1/2/4/6-pole, highpass 1/2/4/6-pole, bandpass 2-pole,
389          bandreject 2-pole.
390        - Fixd potential crash with polynomial interpolator and max. pitch.
391        - If minimum cutoff is defined, remap cutoff controller CC values to really
392          span the entire possible cutoff range (and avoiding a dead controller
393          zone).
394        - Implemented support for loading instrument scripts with 'patch' variables
395          (by patching these script variables with potentially overridden ones by
396          gig Instrument).
397    
398      * SFZ format engine:
399        - Fixed support for regions with loccN/hiccN conditions on more than one
400          MIDI controller.
401        - Fixed internal opcode 'xfin_hivel' falsely being set by user opcode
402          'xfin_lovel' (patch by Christian Czezatke).
403    
404      * Benchmarks:
405        - Fixed benchmarks/triang.cpp falsely having favoured "int math abs"
406          algorithm (since result of 2nd run was not accumulated).
407        - Added benchmark for saw wave (benchmarks/saw.cpp).
408        - Added benchmark for sine wave (benchmarks/sine.cpp).
409        - Added benchmark for square wave (benchmarks/square.cpp).
410        - Increased amount of benchmarks runs by factor 6 to achieve benchmark times
411          which are large enough on modern systems.
