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    
39      * MIDI driver:
40        - VirtualMidiDevice: added method Reset() which is e.g. intended to be used
41          in "panic" / MIDI "all sound off" / MIDI "all note off" situations.
42        - VirtualMidiDevice: release all notes on MIDI CC #120 and CC #123.
43    
44    Version 2.2.0 (9 May 2021)
45    
46      * general changes:
47      - Fixed compiler error in Pool.h.      - Fixed compiler error in Pool.h.
48      - Require C++14 compiler support.      - Require C++14 compiler support.
49      - Autoconf: Added m4/ax_cxx_compile_stdcxx.m4 macro which is used      - Autoconf: Added m4/ax_cxx_compile_stdcxx.m4 macro which is used

95      - Fixed playing noise at the end of a disk stream under certain conditions.      - Fixed playing noise at the end of a disk stream under certain conditions.
96      - Fixed potential crash with high pitch at end of RAM playback.      - Fixed potential crash with high pitch at end of RAM playback.
97        - Added configure checks whether C++ compiler supports so called
98          'designated initializers'.
99        - Added global backtraceAsString() function for debugging purposes
100          (POSIX systems only, no Windows implementation yet).
101        - Thread class: Added new methods pushCancelable(), popCancelable(), name(),
102          nameOfCaller() and setNameOfCaller().
103        - configure: Always check for availability of pthread_testcancel() and use
104          it if so (previously it was only used if explicitly enabled by configure
105          option).
106        - Thread class: raise compiler warning if pthread_testcancel() is not
107          available, because it can lead to deadlocks.
108        - Mutex class: Implemented optional bug detection and deadlock debugging
109          features.
110        - Ref<> class is now thread safe (as lock-free and wait-free
111          implementation).
112        - Fixed compilation error with Bison >= 3.6.0.
113        - Fixed rare crash when switching between instruments that had instrument
114          scripts loaded.
115        - Allow EffectChain::InsertEffect() as alternative to
116          EffectChain::AppendEffect() (i.e. with index equal to current chain size).
117        - ConstCapacityArray class: Fixed bug in remove() method.
118        - Fixed crash on certain MIDI RPN and NRPN messages that occurred if no
119          real-time instrument script was loaded.
120    
121    * Real-time instrument scripts:    * Real-time instrument scripts:
122      - Added method ScriptVM::setExitResultEnabled() which allows to      - Added method ScriptVM::setExitResultEnabled() which allows to

310        "change_amp_lfo_depth()", "change_cutoff_lfo_depth()" and        "change_amp_lfo_depth()", "change_cutoff_lfo_depth()" and
311        "change_pitch_lfo_depth()", to allow e.g. passing value 2000000 to double        "change_pitch_lfo_depth()", to allow e.g. passing value 2000000 to double
312        the LFO frequency / resonance / cutoff frequency.        the LFO frequency / resonance / cutoff frequency.
313        - Reduced code involved for parsing NKSP variable declarations by using 2
314          generalized grammar rules with optional components (i.e. optional value
315          assignment and optional variable qualifiers) instead of previous linear
316          combinations of grammar rules, which also fixes some edge case.
317        - NKSP language parser: track code block locations also by a) raw byte
318          position in NKSP source code string and b) length of that code block in
319          bytes (along to the already existing code block tracking by line/column);
320          and added appropriate new members to public C++ API classes like
321          'firstByte' and 'lengthBytes' to class VMSourceToken and struct CodeBlock.
322        - NKSP language: Added support for 'patch' variable qualifier (capture their
323          locations and allow replacement of their assignment expression via VM C++
324          API).
325        - Fixed incorrect EG times if standard measuring unit was passed to built-in
326          functions "change_attack()", "change_decay()" or "change_release()".
327        - Fixed intermediate function result values never having reflected any
328          standard measuring unit type.
329        - Fixed re-entrant issue with function calls which caused wrong result
330          values if the same function was called multiple times in a term
331          (specifically if metric prefixes were used).
332        - NKSP language: Just throw a warning, not an error if an array variable of
333          size zero was declared.
334        - NKSP language: Allow omitting explicit array size on array variable
335          declaration if combined with immediate value assignment
336          (e.g. declare %foo[] := ( 1, 2, 3 ) ).
337        - NKSP language: emit warning if an array variable was declared with bigger
338          array size than amount of initial values been assigned, and initialize the
339          missing array elements with zero in this case.
340        - Fixed built-in NKSP exit() function to behave as return statement.
341        - NKSP parser: Fixed crash if unary '-' operator was used on a non-number
342          data type.
343        - NKSP VM: Fixed the "release" handler being executed too often under
344          certain situations if polyphonic data was passed from "note" handler to
345          "release" handler.
346        - Fixed memory leak in NKSP parser: string tokens were allocated as C
347          strings and never freed.
348        - Fixed incorrect polyphonic data transfer from wrong note handler to
349          release handler; which also fixes no release handler being executed
350          sometimes, and due to the latter it also fixes potential crashes as some
351          polyphonic script events were never released and the engine hence was
352          running out of free script events.
353        - Fixed crash when handling array results of built-in functions
354          (e.g. "num_elements(by_marks($MARK_1)").
355        - NKSP VM: Fixed dead note events not been removed from user's event groups
356          (i.e. causing incorrect behaviour of built-in NKSP functions by_marks()
357          and set_event_mark() after max. size of event group list was exhausted).
358    
359    * test cases:    * test cases:
360      - Fixed compiler errors in test cases.      - Fixed compiler errors in test cases.

380        "sin()", "cos()", "tan()", "asin()", "acos()", "atan()".        "sin()", "cos()", "tan()", "asin()", "acos()", "atan()".
381      - Added NKSP test cases for unary '+' operator.      - Added NKSP test cases for unary '+' operator.
382      - Added NKSP test cases for core built-in variables.      - Added NKSP test cases for core built-in variables.
383        - Added thorough NKSP test cases for variable declarations.
384

406        - Implemented support for loading instrument scripts with 'patch' variables
407          (by patching these script variables with potentially overridden ones by
408          gig Instrument).
409
