2    
3    * general changes:    * general changes:
4        - AbstractEngineChannel: fixed CCs not being forwarded to all
5          VirtualMIDIDevices.
6        - Fix compiler error with release tarball if no Bison installed
7          (SVN version still requires Flex and Bison being installed).
8    
9      * Real-time instrument scripts:
10        - Fix: Do not share compiled instrument scripts among multiple engine
11          channels (sampler parts) as this can lead to crashes and would allow the
12          same global script variables to be accessible from multiple engine
13          channels which would not be the expected behaviour by instrument script
14          authors.
15    
16      * GigaStudio/Gigasampler format engine:
17        - Use libgig's new IO-per-thread feature to avoid file I/O concurrency
18          issues with .gig file.
19        - Use libgig's new method gig::File::GetSample() with method
20          gig::File::CountSamples() instead of now deprecated
21          gig::File::GetFirstSample() / gig::File::GetNextSample() pair.
22        - Use libgig's new method gig::Instrument::GetRegionAt() with method
23          gig::Instrument:CountRegions() instead of now deprecated
24          gig::Instrument::GetFirstRegion() / gig::Instrument::GetNextRegion() pair.
25        - Use libgig's gig::File::GetInstrument() method with method
26          gig::File::CountInstruments() instead of now deprecated
27          gig::File::GetFirstInstrument() / gig::File::GetNextInstrument() pair.
28        - Show a more detailed error message on terminal if an appropriate editor
29          could not be found for a .gig instrument (if there is not any editor then
30          say so, if there is one but not capable to handle the instrument, then
31          make this case clear to the user; in both cases print the expected
32          location for instrument editor plugins).
33    
34      * SFZ format engine:
35        - Fixed wrong velocity of release triggered samples (most hardware
36          keybaords send note-off with velocyity zero, hence the previous note-on
37          velocity should be used for release triggered samples instead).
38        - sfz.h: Added File::filename() method.
39        - sfz.h: Added File::checkFileModified() method allowing to detect file
40          changes (e.g. by other apps).
41        - sfz.h: Added Instrument::GetFile() method.
42    
43      * MIDI driver:
44        - VirtualMidiDevice: added method Reset() which is e.g. intended to be used
45          in "panic" / MIDI "all sound off" / MIDI "all note off" situations.
46        - VirtualMidiDevice: release all notes on MIDI CC #120 and CC #123.
47    
48    Version 2.2.0 (9 May 2021)
49    
50      * general changes:
51      - Fixed compiler error in Pool.h.      - Fixed compiler error in Pool.h.
52      - Require C++14 compiler support.      - Require C++14 compiler support.
53      - 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 57  Version SVN trunk (?)
57      - RTMath: Implemented floating point comparison methods      - RTMath: Implemented floating point comparison methods
58        fEqual32(float,float) and fEqual64(double,double) which take the        fEqual32(float,float) and fEqual64(double,double) which take the
59        expected floating point tolerances into account.        expected floating point tolerances into account.
60        - Added public API C++ class "LFO", which is a cluster class encapsulating
61          all the sampler's LFO implementations to be used by 3rd party applications
62          (e.g. by Gigedit).
63        - Added int math square LFO implementation.
64        - Added int math saw LFO implementation.
65        - Added numeric complex nr sine LFO implementation.
66        - Marked class LFOTriangleDiHarmonic as deprecated
67          (will be removed in future).
68        - Added LFOAll.h which includes all LFO implementation's header files.
69        - Refactored LFO class names and their file names (PulseLFO -> LFOPulse,
70          LFOSawIntMath -> LFOSawIntMathNew, SawLFO -> LFOSawIntMathOld,
71          SineLFO -> LFOSineBuiltinFn, LFOSine -> LFOSineNumericComplexNr,
72          SquareLFO -> LFOSquarePulse and separated the latter to its own header
73          file).
74        - Renamed type LFOSigned -> LFOTriangleSigned.
75        - Renamed type LFOUnsigned -> LFOTriangleUnsigned.
76        - Using now cubic interpolation as resampling algorithm by default; and
77          linear interpolation is deprecated now.
78        - Event:Init(): memset() entire Event::Param union to zero instead of trying
79          to do that for its individual members; the latter became error prone due
80          to the union's growing complexity meanwhile.
81        - EngineChannel: Overhaul of RPN/NRPN related methods: Added new
82          *Rpn*Parameter*() methods as replacement for previous *Rpn*Controller*()
83          methods and marked the old ones as deprecated; and likewise added new
84          *Nrpn*Parameter*() methods as replacement for previous *Nrpn*Controller*()
85          methods and marked those old ones deprecated as well.
86        - Added support for MIDI CC #38 (data entry LSB): this allows higher value
87          resolution for certain (e.g. hard coded) RPN and NRPN parameters.
88        - Implemented support for compressed RPN/NRPN message sequences (that is to
89          allow processing MIDI data entry messages without always having to be
90          preceded strictly by RPN/NRPN parameter selection messages on each value
91          change).
92        - Added support for MIDI CC #96 (data increment) and MIDI CC #97 (data
93          decrement).
94        - Added support for 'null function RPN/NRPN' (which is RPN/NRPN parameter
95          MSB=127 and LSB=127) and which is disabling subsequent data
96          entry/increment/decrement CC messages.
97        - Fixed crash when editing key groups (a.k.a. exclusive groups) with an
98          instrument editor.
99        - Fixed playing noise at the end of a disk stream under certain conditions.
100        - Fixed potential crash with high pitch at end of RAM playback.
101        - Added configure checks whether C++ compiler supports so called
102          'designated initializers'.
103        - Added global backtraceAsString() function for debugging purposes
104          (POSIX systems only, no Windows implementation yet).
105        - Thread class: Added new methods pushCancelable(), popCancelable(), name(),
106          nameOfCaller() and setNameOfCaller().
107        - configure: Always check for availability of pthread_testcancel() and use
108          it if so (previously it was only used if explicitly enabled by configure
109          option).
110        - Thread class: raise compiler warning if pthread_testcancel() is not
111          available, because it can lead to deadlocks.
112        - Mutex class: Implemented optional bug detection and deadlock debugging
113          features.
114        - Ref<> class is now thread safe (as lock-free and wait-free
115          implementation).
116        - Fixed compilation error with Bison >= 3.6.0.
117        - Fixed rare crash when switching between instruments that had instrument
118          scripts loaded.
119        - Allow EffectChain::InsertEffect() as alternative to
120          EffectChain::AppendEffect() (i.e. with index equal to current chain size).
121        - ConstCapacityArray class: Fixed bug in remove() method.
122        - Fixed crash on certain MIDI RPN and NRPN messages that occurred if no
123          real-time instrument script was loaded.
124    
125    * Real-time instrument scripts:    * Real-time instrument scripts:
126      - Added method ScriptVM::setExitResultEnabled() which allows to      - Added method ScriptVM::setExitResultEnabled() which allows to
# Line 182  Version SVN trunk (?) Line 293  Version SVN trunk (?)
293      - Added built-in script real number constant "~NI_MATH_PI".      - Added built-in script real number constant "~NI_MATH_PI".
294      - Added built-in script real number constant "~NI_MATH_E".      - Added built-in script real number constant "~NI_MATH_E".
295      - NKSP language: Allow unary '+' operator.      - NKSP language: Allow unary '+' operator.
296        - Added built-in script functions "msb()" and "lsb()".
297        - NKSP language: Added support for RPN event handler
298          ("on rpn ... end on" in instrument scripts).
299        - NKSP language: Added support for NRPN event handler
300          ("on nrpn ... end on" in instrument scripts).
301        - Added built-in read-only variables "$RPN_ADDRESS" and "$RPN_VALUE" which
302          may be read from the new RPN/NRPN script handlers to get the (N)RPN
303          parameter that had been changed and its new value.
304        - Added built-in const variables "$NI_CB_TYPE_RPN" and "$NI_CB_TYPE_NRPN"
305          which are identifying the new (N)RPN handlers as such at script runtime.
306        - Implemented built-in script function "set_rpn()".
307        - Implemented built-in script function "set_nrpn()".
308        - Fix: built-in functions returning an array type were broken and caused a
309          crash when the built-in function's (supposed to be array) result value was
310          used by the script VM.
311        - Removed upper value constraint for 2nd argument of built-in functions
312          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
313          "change_pitch_lfo_freq()","change_reso()", "change_cutoff()",
314          "change_amp_lfo_depth()", "change_cutoff_lfo_depth()" and
315          "change_pitch_lfo_depth()", to allow e.g. passing value 2000000 to double
316          the LFO frequency / resonance / cutoff frequency.
317        - Reduced code involved for parsing NKSP variable declarations by using 2
318          generalized grammar rules with optional components (i.e. optional value
319          assignment and optional variable qualifiers) instead of previous linear
320          combinations of grammar rules, which also fixes some edge case.
321        - NKSP language parser: track code block locations also by a) raw byte
322          position in NKSP source code string and b) length of that code block in
323          bytes (along to the already existing code block tracking by line/column);
324          and added appropriate new members to public C++ API classes like
325          'firstByte' and 'lengthBytes' to class VMSourceToken and struct CodeBlock.
326        - NKSP language: Added support for 'patch' variable qualifier (capture their
327          locations and allow replacement of their assignment expression via VM C++
328          API).
329        - Fixed incorrect EG times if standard measuring unit was passed to built-in
330          functions "change_attack()", "change_decay()" or "change_release()".
331        - Fixed intermediate function result values never having reflected any
332          standard measuring unit type.
333        - Fixed re-entrant issue with function calls which caused wrong result
334          values if the same function was called multiple times in a term
335          (specifically if metric prefixes were used).
336        - NKSP language: Just throw a warning, not an error if an array variable of
337          size zero was declared.
338        - NKSP language: Allow omitting explicit array size on array variable
339          declaration if combined with immediate value assignment
340          (e.g. declare %foo[] := ( 1, 2, 3 ) ).
341        - NKSP language: emit warning if an array variable was declared with bigger
342          array size than amount of initial values been assigned, and initialize the
343          missing array elements with zero in this case.
344        - Fixed built-in NKSP exit() function to behave as return statement.
345        - NKSP parser: Fixed crash if unary '-' operator was used on a non-number
346          data type.
347        - NKSP VM: Fixed the "release" handler being executed too often under
348          certain situations if polyphonic data was passed from "note" handler to
349          "release" handler.
350        - Fixed memory leak in NKSP parser: string tokens were allocated as C
351          strings and never freed.
352        - Fixed incorrect polyphonic data transfer from wrong note handler to
353          release handler; which also fixes no release handler being executed
354          sometimes, and due to the latter it also fixes potential crashes as some
355          polyphonic script events were never released and the engine hence was
356          running out of free script events.
357        - Fixed crash when handling array results of built-in functions
358          (e.g. "num_elements(by_marks($MARK_1)").
359        - NKSP VM: Fixed dead note events not been removed from user's event groups
360          (i.e. causing incorrect behaviour of built-in NKSP functions by_marks()
361          and set_event_mark() after max. size of event group list was exhausted).
362    
363    * test cases:    * test cases:
364      - Fixed compiler errors in test cases.      - Fixed compiler errors in test cases.

383        "floor()", "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()",        "floor()", "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()",
384        "sin()", "cos()", "tan()", "asin()", "acos()", "atan()".        "sin()", "cos()", "tan()", "asin()", "acos()", "atan()".
385      - Added NKSP test cases for unary '+' operator.      - Added NKSP test cases for unary '+' operator.
386        - Added NKSP test cases for core built-in variables.
387        - Added thorough NKSP test cases for variable declarations.
388    
389      * GigaStudio/Gigasampler format engine:
390        - LFOTriangleIntMath and LFOTriangleIntAbsMath: Fixed FlipPhase=true
391          behaviour for start_level_mid.
392        - Changed LFO start levels: LFO1 and LFO2 both to mid, LFO3 to max. start
393          level (see discussion "GigaStudio LFO compatibility" on mailing list
394          from 2019-09-26 for details).
395        - Changed default wave form for all 3 LFOs to sine (instead of triangle;
396          see discussion "GigaStudio LFO compatibility" on mailing list from
397          2019-09-26 for details).
398        - Format extension: Added support for different LFO wave forms (currently
399          either sine [default], triangle, saw or square).
400        - Format extension: Added support for LFO phase displacement (0°..360°).
401        - Format extension: Added support for flipping LFO polarity on LFO 3
402          (in the original gig format this was only available for LFO 1 and LFO 2).
403        - Format extension: Support for additional filter types:
404          lowpass 1/2/4/6-pole, highpass 1/2/4/6-pole, bandpass 2-pole,
405          bandreject 2-pole.
406        - Fixd potential crash with polynomial interpolator and max. pitch.
407        - If minimum cutoff is defined, remap cutoff controller CC values to really
408          span the entire possible cutoff range (and avoiding a dead controller
409          zone).
410        - Implemented support for loading instrument scripts with 'patch' variables
411          (by patching these script variables with potentially overridden ones by
412          gig Instrument).
413    
414      * SFZ format engine:
415        - Fixed support for regions with loccN/hiccN conditions on more than one
416          MIDI controller.
417        - Fixed internal opcode 'xfin_hivel' falsely being set by user opcode
418          'xfin_lovel' (patch by Christian Czezatke).
419    
420      * Benchmarks:
421        - Fixed benchmarks/triang.cpp falsely having favoured "int math abs"
422          algorithm (since result of 2nd run was not accumulated).
423        - Added benchmark for saw wave (benchmarks/saw.cpp).
424        - Added benchmark for sine wave (benchmarks/sine.cpp).
425        - Added benchmark for square wave (benchmarks/square.cpp).
426        - Increased amount of benchmarks runs by factor 6 to achieve benchmark times
427          which are large enough on modern systems.
