* 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 |

expected floating point tolerances into account. |
| 39 |
|
- Added public API C++ class "LFO", which is a cluster class encapsulating |
| 40 |
|
all the sampler's LFO implementations to be used by 3rd party applications |
| 41 |
|
(e.g. by Gigedit). |
| 42 |
|
- Added int math square LFO implementation. |
| 43 |
|
- Added int math saw LFO implementation. |
| 44 |
|
- Added numeric complex nr sine LFO implementation. |
| 45 |
|
- Marked class LFOTriangleDiHarmonic as deprecated |
| 46 |
|
(will be removed in future). |
| 47 |
|
- Added LFOAll.h which includes all LFO implementation's header files. |
| 48 |
|
- Refactored LFO class names and their file names (PulseLFO -> LFOPulse, |
| 49 |
|
LFOSawIntMath -> LFOSawIntMathNew, SawLFO -> LFOSawIntMathOld, |
| 50 |
|
SineLFO -> LFOSineBuiltinFn, LFOSine -> LFOSineNumericComplexNr, |
| 51 |
|
SquareLFO -> LFOSquarePulse and separated the latter to its own header |
| 52 |
|
file). |
| 53 |
|
- Renamed type LFOSigned -> LFOTriangleSigned. |
| 54 |
|
- Renamed type LFOUnsigned -> LFOTriangleUnsigned. |
| 55 |
|
- Using now cubic interpolation as resampling algorithm by default; and |
| 56 |
|
linear interpolation is deprecated now. |
| 57 |
|
- Event:Init(): memset() entire Event::Param union to zero instead of trying |
| 58 |
|
to do that for its individual members; the latter became error prone due |
| 59 |
|
to the union's growing complexity meanwhile. |
| 60 |
|
- EngineChannel: Overhaul of RPN/NRPN related methods: Added new |
| 61 |
|
*Rpn*Parameter*() methods as replacement for previous *Rpn*Controller*() |
| 62 |
|
methods and marked the old ones as deprecated; and likewise added new |
| 63 |
|
*Nrpn*Parameter*() methods as replacement for previous *Nrpn*Controller*() |
| 64 |
|
methods and marked those old ones deprecated as well. |
| 65 |
|
- Added support for MIDI CC #38 (data entry LSB): this allows higher value |
| 66 |
|
resolution for certain (e.g. hard coded) RPN and NRPN parameters. |
| 67 |
|
- Implemented support for compressed RPN/NRPN message sequences (that is to |
| 68 |
|
allow processing MIDI data entry messages without always having to be |
| 69 |
|
preceded strictly by RPN/NRPN parameter selection messages on each value |
| 70 |
|
change). |
| 71 |
|
- Added support for MIDI CC #96 (data increment) and MIDI CC #97 (data |
| 72 |
|
decrement). |
| 73 |
|
- Added support for 'null function RPN/NRPN' (which is RPN/NRPN parameter |
| 74 |
|
MSB=127 and LSB=127) and which is disabling subsequent data |
| 75 |
|
entry/increment/decrement CC messages. |
| 76 |
|
- Fixed crash when editing key groups (a.k.a. exclusive groups) with an |
| 77 |
|
instrument editor. |
| 78 |
|
- Fixed playing noise at the end of a disk stream under certain conditions. |
| 79 |
|
- Fixed potential crash with high pitch at end of RAM playback. |
| 80 |
|
- Added configure checks whether C++ compiler supports so called |
| 81 |
|
'designated initializers'. |
| 82 |
|
- Added global backtraceAsString() function for debugging purposes |
| 83 |
|
(POSIX systems only, no Windows implementation yet). |
| 84 |
|
- Thread class: Added new methods pushCancelable(), popCancelable(), name(), |
| 85 |
|
nameOfCaller() and setNameOfCaller(). |
| 86 |
|
- configure: Always check for availability of pthread_testcancel() and use |
| 87 |
|
it if so (previously it was only used if explicitly enabled by configure |
| 88 |
|
option). |
| 89 |
|
- Thread class: raise compiler warning if pthread_testcancel() is not |
| 90 |
|
available, because it can lead to deadlocks. |
| 91 |
|
- Mutex class: Implemented optional bug detection and deadlock debugging |
| 92 |
|
features. |
| 93 |
|
- Ref<> class is now thread safe (as lock-free and wait-free |
| 94 |
|
implementation). |
| 95 |
|
- Fixed compilation error with Bison >= 3.6.0. |
| 96 |
|
- Fixed rare crash when switching between instruments that had instrument |
| 97 |
|
scripts loaded. |
| 98 |
|
- Allow EffectChain::InsertEffect() as alternative to |
| 99 |
|
EffectChain::AppendEffect() (i.e. with index equal to current chain size). |
| 100 |
|
- ConstCapacityArray class: Fixed bug in remove() method. |
| 101 |
|
- Fixed crash on certain MIDI RPN and NRPN messages that occurred if no |
| 102 |
|
real-time instrument script was loaded. |

prefixes at all. |
| 243 |
|
- Fixed the following built-in functions having misinterpreted values given |
| 244 |
|
with unit type (for their 2nd argument) as if they were relative values |
| 245 |
|
(that is as if they were passed without a unit type): "change_attack()", |
| 246 |
|
"change_decay()", "change_release()", "change_cutoff_attack()", |
| 247 |
|
"change_cutoff_decay()", "change_cutoff_release()". |
| 248 |
|
- Fixed the following built-in functions having applied completely wrong |
| 249 |
|
'final' values: "change_sustain()", "change_cutoff_sustain()" (since the |
| 250 |
|
respective EGs being their modulation sink assume uint data type with |
| 251 |
|
value range 0..1000 instead of 0.0..1.0. |
| 252 |
|
- Added individual parse-time checks of function arguments for the following |
| 253 |
|
built-in functions: "play_note()", "note_off()", "set_event_mark()", |
| 254 |
|
"delete_event_mark()", "by_marks()", "change_cutoff()", "change_attack()", |
| 255 |
|
"change_decay()", "change_release()", "change_cutoff_attack()", |
| 256 |
|
"change_cutoff_decay()", "change_cutoff_release()", |
| 257 |
|
"change_amp_lfo_freq()", "change_cutoff_lfo_freq()", |
| 258 |
|
"change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()" and |
| 259 |
|
"change_pan_time()". |
| 260 |
|
- Don't abort function call if unit type was used and at the same time |
| 261 |
|
'final' operator was omitted for the primary value argument of the |
| 262 |
|
following built-in functions: "change_cutoff()", "change_attack()", |
| 263 |
|
"change_decay()", "change_release()", "change_cutoff_attack()", |
| 264 |
|
"change_cutoff_decay()", "change_cutoff_release()", |
| 265 |
|
"change_amp_lfo_freq()", "change_cutoff_lfo_freq()", |
| 266 |
|
"change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()", |
| 267 |
|
"change_pan_time()", instead imply 'final'ness at runtime and raise an |
| 268 |
|
appropriate parser warning at parse time. |
| 269 |
|
- Added built-in real number functions "round()", "ceil()", "floor()", |
| 270 |
|
"sqrt()", "log()", "log2()", "log10()", "exp()", "pow()", "sin()", |
| 271 |
|
"cos()", "tan()", "asin()", "acos()", "atan()". |
| 272 |
|
- Added built-in script real number constant "~NI_MATH_PI". |
| 273 |
|
- Added built-in script real number constant "~NI_MATH_E". |
| 274 |
|
- NKSP language: Allow unary '+' operator. |
| 275 |
|
- Added built-in script functions "msb()" and "lsb()". |
| 276 |
|
- NKSP language: Added support for RPN event handler |
| 277 |
|
("on rpn ... end on" in instrument scripts). |
| 278 |
|
- NKSP language: Added support for NRPN event handler |
| 279 |
|
("on nrpn ... end on" in instrument scripts). |
| 280 |
|
- Added built-in read-only variables "$RPN_ADDRESS" and "$RPN_VALUE" which |
| 281 |
|
may be read from the new RPN/NRPN script handlers to get the (N)RPN |
| 282 |
|
parameter that had been changed and its new value. |
| 283 |
|
- Added built-in const variables "$NI_CB_TYPE_RPN" and "$NI_CB_TYPE_NRPN" |
| 284 |
|
which are identifying the new (N)RPN handlers as such at script runtime. |
| 285 |
|
- Implemented built-in script function "set_rpn()". |
| 286 |
|
- Implemented built-in script function "set_nrpn()". |
| 287 |
|
- Fix: built-in functions returning an array type were broken and caused a |
| 288 |
|
crash when the built-in function's (supposed to be array) result value was |
| 289 |
|
used by the script VM. |
| 290 |
|
- Removed upper value constraint for 2nd argument of built-in functions |
| 291 |
|
"change_amp_lfo_freq()", "change_cutoff_lfo_freq()", |
| 292 |
|
"change_pitch_lfo_freq()","change_reso()", "change_cutoff()", |
| 293 |
|
"change_amp_lfo_depth()", "change_cutoff_lfo_depth()" and |
| 294 |
|
"change_pitch_lfo_depth()", to allow e.g. passing value 2000000 to double |
| 295 |
|
the LFO frequency / resonance / cutoff frequency. |
| 296 |
|
- Reduced code involved for parsing NKSP variable declarations by using 2 |
| 297 |
|
generalized grammar rules with optional components (i.e. optional value |
| 298 |
|
assignment and optional variable qualifiers) instead of previous linear |
| 299 |
|
combinations of grammar rules, which also fixes some edge case. |
| 300 |
|
- NKSP language parser: track code block locations also by a) raw byte |
| 301 |
|
position in NKSP source code string and b) length of that code block in |
| 302 |
|
bytes (along to the already existing code block tracking by line/column); |
| 303 |
|
and added appropriate new members to public C++ API classes like |
| 304 |
|
'firstByte' and 'lengthBytes' to class VMSourceToken and struct CodeBlock. |
| 305 |
|
- NKSP language: Added support for 'patch' variable qualifier (capture their |
| 306 |
|
locations and allow replacement of their assignment expression via VM C++ |
| 307 |
|
API). |
| 308 |
|
- Fixed incorrect EG times if standard measuring unit was passed to built-in |
| 309 |
|
functions "change_attack()", "change_decay()" or "change_release()". |
| 310 |
|
- Fixed intermediate function result values never having reflected any |
| 311 |
|
standard measuring unit type. |
| 312 |
|
- Fixed re-entrant issue with function calls which caused wrong result |
| 313 |
|
values if the same function was called multiple times in a term |
| 314 |
|
(specifically if metric prefixes were used). |
| 315 |
|
- NKSP language: Just throw a warning, not an error if an array variable of |
| 316 |
|
size zero was declared. |
| 317 |
|
- NKSP language: Allow omitting explicit array size on array variable |
| 318 |
|
declaration if combined with immediate value assignment |
| 319 |
|
(e.g. declare %foo[] := ( 1, 2, 3 ) ). |
| 320 |
|
- NKSP language: emit warning if an array variable was declared with bigger |
| 321 |
|
array size than amount of initial values been assigned, and initialize the |
| 322 |
|
missing array elements with zero in this case. |
| 323 |
|
- Fixed built-in NKSP exit() function to behave as return statement. |
| 324 |
|
- NKSP parser: Fixed crash if unary '-' operator was used on a non-number |
| 325 |
|
data type. |
| 326 |
|
- NKSP VM: Fixed the "release" handler being executed too often under |
| 327 |
|
certain situations if polyphonic data was passed from "note" handler to |
| 328 |
|
"release" handler. |
| 329 |
|
- Fixed memory leak in NKSP parser: string tokens were allocated as C |
| 330 |
|
strings and never freed. |
| 331 |
|
- Fixed incorrect polyphonic data transfer from wrong note handler to |
| 332 |
|
release handler; which also fixes no release handler being executed |
| 333 |
|
sometimes, and due to the latter it also fixes potential crashes as some |
| 334 |
|
polyphonic script events were never released and the engine hence was |
| 335 |
|
running out of free script events. |
| 336 |
|
- Fixed crash when handling array results of built-in functions |
| 337 |
|
(e.g. "num_elements(by_marks($MARK_1)"). |
| 338 |
|
- NKSP VM: Fixed dead note events not been removed from user's event groups |
| 339 |
|
(i.e. causing incorrect behaviour of built-in NKSP functions by_marks() |
| 340 |
|
and set_event_mark() after max. size of event group list was exhausted). |
| 341 |

| 363 |
|

|
- Added NKSP test cases for unary '+' operator. |
| 365 |
|
- Added NKSP test cases for core built-in variables. |
| 366 |
|
- Added thorough NKSP test cases for variable declarations. |

| 368 |
|
* GigaStudio/Gigasampler format engine: |
| 369 |
|
- LFOTriangleIntMath and LFOTriangleIntAbsMath: Fixed FlipPhase=true |
| 370 |
|
behaviour for start_level_mid. |
| 371 |
|
- Changed LFO start levels: LFO1 and LFO2 both to mid, LFO3 to max. start |
| 372 |
|
level (see discussion "GigaStudio LFO compatibility" on mailing list |
| 373 |
|
from 2019-09-26 for details). |
| 374 |
|
- Changed default wave form for all 3 LFOs to sine (instead of triangle; |
| 375 |
|
see discussion "GigaStudio LFO compatibility" on mailing list from |
| 376 |
|
2019-09-26 for details). |
| 377 |
|
- Format extension: Added support for different LFO wave forms (currently |
| 378 |
|
either sine [default], triangle, saw or square). |
| 379 |
|
- Format extension: Added support for LFO phase displacement (0°..360°). |
| 380 |
|
- Format extension: Added support for flipping LFO polarity on LFO 3 |
| 381 |
|
(in the original gig format this was only available for LFO 1 and LFO 2). |
| 382 |
|
- Format extension: Support for additional filter types: |
| 383 |
|
lowpass 1/2/4/6-pole, highpass 1/2/4/6-pole, bandpass 2-pole, |
| 384 |
|
bandreject 2-pole. |
| 385 |
|
- Fixd potential crash with polynomial interpolator and max. pitch. |
| 386 |
|
- If minimum cutoff is defined, remap cutoff controller CC values to really |
| 387 |
|
span the entire possible cutoff range (and avoiding a dead controller |
| 388 |
|
zone). |
| 389 |
|
- Implemented support for loading instrument scripts with 'patch' variables |
| 390 |
|
(by patching these script variables with potentially overridden ones by |
| 391 |
|
gig Instrument). |
| 392 |
|
|
| 393 |
|
* SFZ format engine: |
| 394 |
|
- Fixed support for regions with loccN/hiccN conditions on more than one |
| 395 |
|
MIDI controller. |
| 396 |
|
- Fixed internal opcode 'xfin_hivel' falsely being set by user opcode |
| 397 |
|
'xfin_lovel' (patch by Christian Czezatke). |
| 398 |
|
|
| 399 |
|
* Benchmarks: |
| 400 |
|
- Fixed benchmarks/triang.cpp falsely having favoured "int math abs" |
| 401 |
|
algorithm (since result of 2nd run was not accumulated). |
| 402 |
|
- Added benchmark for saw wave (benchmarks/saw.cpp). |
| 403 |
|
- Added benchmark for sine wave (benchmarks/sine.cpp). |
| 404 |
|
- Added benchmark for square wave (benchmarks/square.cpp). |
| 405 |
|
- Increased amount of benchmarks runs by factor 6 to achieve benchmark times |
| 406 |
|
which are large enough on modern systems. |
