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

70      - Added support for MIDI CC #38 (data entry LSB): this allows higher value      - 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.        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:

288      - Added built-in const variables "$NI_CB_TYPE_RPN" and "$NI_CB_TYPE_NRPN"      - 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.        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

389        bandreject 2-pole.        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
