3      * GigaStudio/Gigasampler format engine:
4        - 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        - Use libgig's new method gig::Instrument::GetRegionAt() with method
10          gig::Instrument:CountRegions() instead of now deprecated
11          gig::Instrument::GetFirstRegion() / gig::Instrument::GetNextRegion() pair.
12        - Use libgig's gig::File::GetInstrument() method with method
13          gig::File::CountInstruments() instead of now deprecated

25      - RTMath: Implemented floating point comparison methods      - RTMath: Implemented floating point comparison methods
26        fEqual32(float,float) and fEqual64(double,double) which take the        fEqual32(float,float) and fEqual64(double,double) which take the
27        expected floating point tolerances into account.        expected floating point tolerances into account.
28        - Added public API C++ class "LFO", which is a cluster class encapsulating
29          all the sampler's LFO implementations to be used by 3rd party applications
30          (e.g. by Gigedit).
31        - Added int math square LFO implementation.
32        - Added int math saw LFO implementation.
33        - Added numeric complex nr sine LFO implementation.
34        - Marked class LFOTriangleDiHarmonic as deprecated
35          (will be removed in future).
36        - Added LFOAll.h which includes all LFO implementation's header files.
37        - Refactored LFO class names and their file names (PulseLFO -> LFOPulse,
38          LFOSawIntMath -> LFOSawIntMathNew, SawLFO -> LFOSawIntMathOld,
39          SineLFO -> LFOSineBuiltinFn, LFOSine -> LFOSineNumericComplexNr,
40          SquareLFO -> LFOSquarePulse and separated the latter to its own header
41          file).
42        - Renamed type LFOSigned -> LFOTriangleSigned.
43        - Renamed type LFOUnsigned -> LFOTriangleUnsigned.
44        - Using now cubic interpolation as resampling algorithm by default; and
45          linear interpolation is deprecated now.
46        - Event:Init(): memset() entire Event::Param union to zero instead of trying
47          to do that for its individual members; the latter became error prone due
48          to the union's growing complexity meanwhile.
49        - EngineChannel: Overhaul of RPN/NRPN related methods: Added new
50          *Rpn*Parameter*() methods as replacement for previous *Rpn*Controller*()
51          methods and marked the old ones as deprecated; and likewise added new
52          *Nrpn*Parameter*() methods as replacement for previous *Nrpn*Controller*()
53          methods and marked those old ones deprecated as well.
54        - Added support for MIDI CC #38 (data entry LSB): this allows higher value
55          resolution for certain (e.g. hard coded) RPN and NRPN parameters.
56        - Implemented support for compressed RPN/NRPN message sequences (that is to
57          allow processing MIDI data entry messages without always having to be
58          preceded strictly by RPN/NRPN parameter selection messages on each value
59          change).
60        - Added support for MIDI CC #96 (data increment) and MIDI CC #97 (data
61          decrement).
62        - Added support for 'null function RPN/NRPN' (which is RPN/NRPN parameter
63          MSB=127 and LSB=127) and which is disabling subsequent data
64          entry/increment/decrement CC messages.
65        - Fixed crash when editing key groups (a.k.a. exclusive groups) with an
66          instrument editor.
67        - Fixed playing noise at the end of a disk stream under certain conditions.
68        - Fixed potential crash with high pitch at end of RAM playback.
69        - Added configure checks whether C++ compiler supports so called
70          'designated initializers'.
71        - Added global backtraceAsString() function for debugging purposes
72          (POSIX systems only, no Windows implementation yet).
73        - Thread class: Added new methods pushCancelable(), popCancelable(), name(),
74          nameOfCaller() and setNameOfCaller().
75        - configure: Always check for availability of pthread_testcancel() and use
76          it if so (previously it was only used if explicitly enabled by configure
77          option).
78        - Thread class: raise compiler warning if pthread_testcancel() is not
79          available, because it can lead to deadlocks.
80        - Mutex class: Implemented optional bug detection and deadlock debugging
81          features.
82        - Ref<> class is now thread safe (as lock-free and wait-free
83          implementation).
84        - Fixed compilation error with Bison >= 3.6.0.
85        - Fixed rare crash when switching between instruments that had instrument
86          scripts loaded.
87        - Allow EffectChain::InsertEffect() as alternative to
88          EffectChain::AppendEffect() (i.e. with index equal to current chain size).
89        - ConstCapacityArray class: Fixed bug in remove() method.
90        - Fixed crash on certain MIDI RPN and NRPN messages that occurred if no
91          real-time instrument script was loaded.
92    
93    * Real-time instrument scripts:    * Real-time instrument scripts:
94      - Added method ScriptVM::setExitResultEnabled() which allows to      - Added method ScriptVM::setExitResultEnabled() which allows to
# Line 182  Version SVN trunk (?) Line 261  Version SVN trunk (?)
261      - Added built-in script real number constant "~NI_MATH_PI".      - Added built-in script real number constant "~NI_MATH_PI".
262      - Added built-in script real number constant "~NI_MATH_E".      - Added built-in script real number constant "~NI_MATH_E".
263      - NKSP language: Allow unary '+' operator.      - NKSP language: Allow unary '+' operator.
264        - Added built-in script functions "msb()" and "lsb()".
265        - NKSP language: Added support for RPN event handler
266          ("on rpn ... end on" in instrument scripts).
267        - NKSP language: Added support for NRPN event handler
268          ("on nrpn ... end on" in instrument scripts).
269        - Added built-in read-only variables "$RPN_ADDRESS" and "$RPN_VALUE" which
270          may be read from the new RPN/NRPN script handlers to get the (N)RPN
271          parameter that had been changed and its new value.
272        - Added built-in const variables "$NI_CB_TYPE_RPN" and "$NI_CB_TYPE_NRPN"
273          which are identifying the new (N)RPN handlers as such at script runtime.
274        - Implemented built-in script function "set_rpn()".
275        - Implemented built-in script function "set_nrpn()".
276        - Fix: built-in functions returning an array type were broken and caused a
277          crash when the built-in function's (supposed to be array) result value was
278          used by the script VM.
279        - Removed upper value constraint for 2nd argument of built-in functions
280          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
281          "change_pitch_lfo_freq()","change_reso()", "change_cutoff()",
282          "change_amp_lfo_depth()", "change_cutoff_lfo_depth()" and
283          "change_pitch_lfo_depth()", to allow e.g. passing value 2000000 to double
284          the LFO frequency / resonance / cutoff frequency.
285        - Reduced code involved for parsing NKSP variable declarations by using 2
286          generalized grammar rules with optional components (i.e. optional value
287          assignment and optional variable qualifiers) instead of previous linear
288          combinations of grammar rules, which also fixes some edge case.
289        - NKSP language parser: track code block locations also by a) raw byte
290          position in NKSP source code string and b) length of that code block in
291          bytes (along to the already existing code block tracking by line/column);
292          and added appropriate new members to public C++ API classes like
293          'firstByte' and 'lengthBytes' to class VMSourceToken and struct CodeBlock.
294        - NKSP language: Added support for 'patch' variable qualifier (capture their
295          locations and allow replacement of their assignment expression via VM C++
296          API).
297        - Fixed incorrect EG times if standard measuring unit was passed to built-in
298          functions "change_attack()", "change_decay()" or "change_release()".
299        - Fixed intermediate function result values never having reflected any
300          standard measuring unit type.
301        - Fixed re-entrant issue with function calls which caused wrong result
302          values if the same function was called multiple times in a term
303          (specifically if metric prefixes were used).
304        - NKSP language: Just throw a warning, not an error if an array variable of
305          size zero was declared.
306        - NKSP language: Allow omitting explicit array size on array variable
307          declaration if combined with immediate value assignment
308          (e.g. declare %foo[] := ( 1, 2, 3 ) ).
309        - NKSP language: emit warning if an array variable was declared with bigger
310          array size than amount of initial values been assigned, and initialize the
311          missing array elements with zero in this case.
312        - Fixed built-in NKSP exit() function to behave as return statement.
313        - NKSP parser: Fixed crash if unary '-' operator was used on a non-number
314          data type.
315        - NKSP VM: Fixed the "release" handler being executed too often under
316          certain situations if polyphonic data was passed from "note" handler to
317          "release" handler.
318        - Fixed memory leak in NKSP parser: string tokens were allocated as C
319          strings and never freed.
320        - Fixed incorrect polyphonic data transfer from wrong note handler to
321          release handler; which also fixes no release handler being executed
322          sometimes, and due to the latter it also fixes potential crashes as some
323          polyphonic script events were never released and the engine hence was
324          running out of free script events.
325        - Fixed crash when handling array results of built-in functions
326          (e.g. "num_elements(by_marks($MARK_1)").
327        - NKSP VM: Fixed dead note events not been removed from user's event groups
328          (i.e. causing incorrect behaviour of built-in NKSP functions by_marks()
329          and set_event_mark() after max. size of event group list was exhausted).
330    
331    * test cases:    * test cases:
332      - Fixed compiler errors in test cases.      - Fixed compiler errors in test cases.

351        "floor()", "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()",        "floor()", "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()",
352        "sin()", "cos()", "tan()", "asin()", "acos()", "atan()".        "sin()", "cos()", "tan()", "asin()", "acos()", "atan()".
353      - Added NKSP test cases for unary '+' operator.      - Added NKSP test cases for unary '+' operator.
354        - Added NKSP test cases for core built-in variables.
355        - Added thorough NKSP test cases for variable declarations.

357    * GigaStudio/Gigasampler format engine:    * GigaStudio/Gigasampler format engine:
358      - LFOTriangleIntMath and LFOTriangleIntAbsMath: Fixed FlipPhase=true      - LFOTriangleIntMath and LFOTriangleIntAbsMath: Fixed FlipPhase=true
359        behaviour for start_level_mid.        behaviour for start_level_mid.
360        - Changed LFO start levels: LFO1 and LFO2 both to mid, LFO3 to max. start
361          level (see discussion "GigaStudio LFO compatibility" on mailing list
362          from 2019-09-26 for details).
363        - Changed default wave form for all 3 LFOs to sine (instead of triangle;
364          see discussion "GigaStudio LFO compatibility" on mailing list from
365          2019-09-26 for details).
366        - Format extension: Added support for different LFO wave forms (currently
367          either sine [default], triangle, saw or square).
368        - Format extension: Added support for LFO phase displacement (0°..360°).
369        - Format extension: Added support for flipping LFO polarity on LFO 3
370          (in the original gig format this was only available for LFO 1 and LFO 2).
371        - Format extension: Support for additional filter types:
372          lowpass 1/2/4/6-pole, highpass 1/2/4/6-pole, bandpass 2-pole,
373          bandreject 2-pole.
374        - Fixd potential crash with polynomial interpolator and max. pitch.
375        - If minimum cutoff is defined, remap cutoff controller CC values to really
376          span the entire possible cutoff range (and avoiding a dead controller
377          zone).
378        - Implemented support for loading instrument scripts with 'patch' variables
379          (by patching these script variables with potentially overridden ones by
380          gig Instrument).
381    
382    * SFZ format engine:    * SFZ format engine:
383      - Fixed support for regions with loccN/hiccN conditions on more than one      - Fixed support for regions with loccN/hiccN conditions on more than one
384        MIDI controller.        MIDI controller.
385        - Fixed internal opcode 'xfin_hivel' falsely being set by user opcode
386          'xfin_lovel' (patch by Christian Czezatke).
387    
388      * Benchmarks:
389        - Fixed benchmarks/triang.cpp falsely having favoured "int math abs"
390          algorithm (since result of 2nd run was not accumulated).
391        - Added benchmark for saw wave (benchmarks/saw.cpp).
392        - Added benchmark for sine wave (benchmarks/sine.cpp).
393        - Added benchmark for square wave (benchmarks/square.cpp).
394        - Increased amount of benchmarks runs by factor 6 to achieve benchmark times
395          which are large enough on modern systems.
