* Real-time instrument scripts: |
| 4 |
|
- Fix: Do not share compiled instrument scripts among multiple engine |
| 5 |
|
channels (sampler parts) as this can lead to crashes and would allow the |
| 6 |
|
same global script variables to be accessible from multiple engine |
| 7 |
|
channels which would not be the expected behaviour by instrument script |
| 8 |
|
authors. |
| 9 |
|
|
| 10 |
|
* GigaStudio/Gigasampler format engine: |
| 11 |
|
- Use libgig's new IO-per-thread feature to avoid file I/O concurrency |
| 12 |
|
issues with .gig file. |
| 13 |
|
- Use libgig's new method gig::File::GetSample() with method |
| 14 |
|
gig::File::CountSamples() instead of now deprecated |
| 15 |
|
gig::File::GetFirstSample() / gig::File::GetNextSample() pair. |
| 16 |
|
- Use libgig's new method gig::Instrument::GetRegionAt() with method |
| 17 |
|
gig::Instrument:CountRegions() instead of now deprecated |
| 18 |
|
gig::Instrument::GetFirstRegion() / gig::Instrument::GetNextRegion() pair. |
| 19 |
|
- Use libgig's gig::File::GetInstrument() method with method |
| 20 |
|
gig::File::CountInstruments() instead of now deprecated |
| 21 |
|
gig::File::GetFirstInstrument() / gig::File::GetNextInstrument() pair. |
| 22 |
|
|
| 23 |
|
* MIDI driver: |
| 24 |
|
- VirtualMidiDevice: added method Reset() which is e.g. intended to be used |
| 25 |
|
in "panic" / MIDI "all sound off" / MIDI "all note off" situations. |
| 26 |
|
- VirtualMidiDevice: release all notes on MIDI CC #120 and CC #123. |

|
- Fixed playing noise at the end of a disk stream under certain conditions. |
| 80 |
|
- Fixed potential crash with high pitch at end of RAM playback. |
| 81 |
|
- Added configure checks whether C++ compiler supports so called |
| 82 |
|
'designated initializers'. |
| 83 |
|
- Added global backtraceAsString() function for debugging purposes |
| 84 |
|
(POSIX systems only, no Windows implementation yet). |
| 85 |
|
- Thread class: Added new methods pushCancelable(), popCancelable(), name(), |
| 86 |
|
nameOfCaller() and setNameOfCaller(). |
| 87 |
|
- configure: Always check for availability of pthread_testcancel() and use |
| 88 |
|
it if so (previously it was only used if explicitly enabled by configure |
| 89 |
|
option). |
| 90 |
|
- Thread class: raise compiler warning if pthread_testcancel() is not |
| 91 |
|
available, because it can lead to deadlocks. |
| 92 |
|
- Mutex class: Implemented optional bug detection and deadlock debugging |
| 93 |
|
features. |
| 94 |
|
- Ref<> class is now thread safe (as lock-free and wait-free |
| 95 |
|
implementation). |
| 96 |
|
- Fixed compilation error with Bison >= 3.6.0. |
| 97 |
|
- Fixed rare crash when switching between instruments that had instrument |
| 98 |
|
scripts loaded. |
| 99 |
|
- Allow EffectChain::InsertEffect() as alternative to |
| 100 |
|
EffectChain::AppendEffect() (i.e. with index equal to current chain size). |
| 101 |
|
- ConstCapacityArray class: Fixed bug in remove() method. |
| 102 |
|
- Fixed crash on certain MIDI RPN and NRPN messages that occurred if no |
| 103 |
|
real-time instrument script was loaded. |

- Reduced code involved for parsing NKSP variable declarations by using 2 |
| 298 |
|
generalized grammar rules with optional components (i.e. optional value |
| 299 |
|
assignment and optional variable qualifiers) instead of previous linear |
| 300 |
|
combinations of grammar rules, which also fixes some edge case. |
| 301 |
|
- NKSP language parser: track code block locations also by a) raw byte |
| 302 |
|
position in NKSP source code string and b) length of that code block in |
| 303 |
|
bytes (along to the already existing code block tracking by line/column); |
| 304 |
|
and added appropriate new members to public C++ API classes like |
| 305 |
|
'firstByte' and 'lengthBytes' to class VMSourceToken and struct CodeBlock. |
| 306 |
|
- NKSP language: Added support for 'patch' variable qualifier (capture their |
| 307 |
|
locations and allow replacement of their assignment expression via VM C++ |
| 308 |
|
API). |
| 309 |
|
- Fixed incorrect EG times if standard measuring unit was passed to built-in |
| 310 |
|
functions "change_attack()", "change_decay()" or "change_release()". |
| 311 |
|
- Fixed intermediate function result values never having reflected any |
| 312 |
|
standard measuring unit type. |
| 313 |
|
- Fixed re-entrant issue with function calls which caused wrong result |
| 314 |
|
values if the same function was called multiple times in a term |
| 315 |
|
(specifically if metric prefixes were used). |
| 316 |
|
- NKSP language: Just throw a warning, not an error if an array variable of |
| 317 |
|
size zero was declared. |
| 318 |
|
- NKSP language: Allow omitting explicit array size on array variable |
| 319 |
|
declaration if combined with immediate value assignment |
| 320 |
|
(e.g. declare %foo[] := ( 1, 2, 3 ) ). |
| 321 |
|
- NKSP language: emit warning if an array variable was declared with bigger |
| 322 |
|
array size than amount of initial values been assigned, and initialize the |
| 323 |
|
missing array elements with zero in this case. |
| 324 |
|
- Fixed built-in NKSP exit() function to behave as return statement. |
| 325 |
|
- NKSP parser: Fixed crash if unary '-' operator was used on a non-number |
| 326 |
|
data type. |
| 327 |
|
- NKSP VM: Fixed the "release" handler being executed too often under |
| 328 |
|
certain situations if polyphonic data was passed from "note" handler to |
| 329 |
|
"release" handler. |
| 330 |
|
- Fixed memory leak in NKSP parser: string tokens were allocated as C |
| 331 |
|
strings and never freed. |
| 332 |
|
- Fixed incorrect polyphonic data transfer from wrong note handler to |
| 333 |
|
release handler; which also fixes no release handler being executed |
| 334 |
|
sometimes, and due to the latter it also fixes potential crashes as some |
| 335 |
|
polyphonic script events were never released and the engine hence was |
| 336 |
|
running out of free script events. |
| 337 |
|
- Fixed crash when handling array results of built-in functions |
| 338 |
|
(e.g. "num_elements(by_marks($MARK_1)"). |
| 339 |
|
- NKSP VM: Fixed dead note events not been removed from user's event groups |
| 340 |
|
(i.e. causing incorrect behaviour of built-in NKSP functions by_marks() |
| 341 |
|
and set_event_mark() after max. size of event group list was exhausted). |
