3      * GigaStudio/Gigasampler format engine:
4        - Use libgig's new IO-per-thread feature to avoid file I/O concurrency
5          issues with .gig file.

16      - RTMath: Implemented floating point comparison methods      - RTMath: Implemented floating point comparison methods
17        fEqual32(float,float) and fEqual64(double,double) which take the        fEqual32(float,float) and fEqual64(double,double) which take the
18        expected floating point tolerances into account.        expected floating point tolerances into account.
19        - Added public API C++ class "LFO", which is a cluster class encapsulating
20          all the sampler's LFO implementations to be used by 3rd party applications
21          (e.g. by Gigedit).
22        - Added int math square LFO implementation.
23        - Added int math saw LFO implementation.
24        - Added numeric complex nr sine LFO implementation.
25        - Marked class LFOTriangleDiHarmonic as deprecated
26          (will be removed in future).
27        - Added LFOAll.h which includes all LFO implementation's header files.
28        - Refactored LFO class names and their file names (PulseLFO -> LFOPulse,
29          LFOSawIntMath -> LFOSawIntMathNew, SawLFO -> LFOSawIntMathOld,
30          SineLFO -> LFOSineBuiltinFn, LFOSine -> LFOSineNumericComplexNr,
31          SquareLFO -> LFOSquarePulse and separated the latter to its own header
32          file).
33        - Renamed type LFOSigned -> LFOTriangleSigned.
34        - Renamed type LFOUnsigned -> LFOTriangleUnsigned.
35        - Using now cubic interpolation as resampling algorithm by default; and
36          linear interpolation is deprecated now.
37        - Event:Init(): memset() entire Event::Param union to zero instead of trying
38          to do that for its individual members; the latter became error prone due
39          to the union's growing complexity meanwhile.
40        - EngineChannel: Overhaul of RPN/NRPN related methods: Added new
41          *Rpn*Parameter*() methods as replacement for previous *Rpn*Controller*()
42          methods and marked the old ones as deprecated; and likewise added new
43          *Nrpn*Parameter*() methods as replacement for previous *Nrpn*Controller*()
44          methods and marked those old ones deprecated as well.
45        - Added support for MIDI CC #38 (data entry LSB): this allows higher value
46          resolution for certain (e.g. hard coded) RPN and NRPN parameters.
47        - Implemented support for compressed RPN/NRPN message sequences (that is to
48          allow processing MIDI data entry messages without always having to be
49          preceded strictly by RPN/NRPN parameter selection messages on each value
50          change).
51        - Added support for MIDI CC #96 (data increment) and MIDI CC #97 (data
52          decrement).
53        - Added support for 'null function RPN/NRPN' (which is RPN/NRPN parameter
54          MSB=127 and LSB=127) and which is disabling subsequent data
55          entry/increment/decrement CC messages.
56        - Fixed crash when editing key groups (a.k.a. exclusive groups) with an
57          instrument editor.
58        - Fixed playing noise at the end of a disk stream under certain conditions.
59        - Fixed potential crash with high pitch at end of RAM playback.
60        - Added configure checks whether C++ compiler supports so called
61          'designated initializers'.
62        - Added global backtraceAsString() function for debugging purposes
63          (POSIX systems only, no Windows implementation yet).
64        - Thread class: Added new methods pushCancelable(), popCancelable(), name(),
65          nameOfCaller() and setNameOfCaller().
66        - configure: Always check for availability of pthread_testcancel() and use
67          it if so (previously it was only used if explicitly enabled by configure
68          option).
69        - Thread class: raise compiler warning if pthread_testcancel() is not
70          available, because it can lead to deadlocks.
71        - Mutex class: Implemented optional bug detection and deadlock debugging
72          features.
73        - Ref<> class is now thread safe (as lock-free and wait-free
74          implementation).
75        - Fixed compilation error with Bison >= 3.6.0.
76        - Fixed rare crash when switching between instruments that had instrument
77          scripts loaded.
78        - Allow EffectChain::InsertEffect() as alternative to
79          EffectChain::AppendEffect() (i.e. with index equal to current chain size).
80        - ConstCapacityArray class: Fixed bug in remove() method.
81        - Fixed crash on certain MIDI RPN and NRPN messages that occurred if no
82          real-time instrument script was loaded.
83    
84    * Real-time instrument scripts:    * Real-time instrument scripts:
85      - Added method ScriptVM::setExitResultEnabled() which allows to      - Added method ScriptVM::setExitResultEnabled() which allows to

195        NumberBinaryOp, VMScalarNumberResultFunction -> VMNumberResultFunction,        NumberBinaryOp, VMScalarNumberResultFunction -> VMNumberResultFunction,
196        method VMExpr::asScalarNumberExpr() -> VMExpr::asNumber(), function        method VMExpr::asScalarNumberExpr() -> VMExpr::asNumber(), function
197        isScalarNumber() -> isNumber()).        isScalarNumber() -> isNumber()).
198        - NKSP VM API: Added 4 overridden methods to class VMNumberExpr:
199          evalCastInt(MetricPrefix_t), evalCastInt(MetricPrefix_t,MetricPrefix_t),
200          evalCastReal(MetricPrefix_t), evalCastReal(MetricPrefix_t,MetricPrefix_t)
201          as convenient methods for automatically converting values to expected
202          metric value basis.
203        - Built-in function "wait()" accepts now both integers and real numbers as
204          argument.
205        - NKSP VM API cleanup: Get rid of legacy method
206          VMFunction::argType(vmint iArg) which was already superseded by its new
207          replacement VMFunction::acceptsArgType(vmint iArg, ExprType_t type).
208        - NKSP parser: if wrong argument type was passed to a built-in function and
209          that built-in function accepts more than one data type for the argument,
210          then show all supported data types as parser error message.
211        - Built-in function "play_note()" accepts now real numbers and seconds as
212          unit type as well for its 3rd and 4th function arguments.
213        - The following built-in functions accept now real numbers as well for their
214          2nd function argument: "change_vol()", "change_tune()", "change_cutoff()",
215          "change_attack()", "change_decay()", "change_release()",
216          "change_sustain()", "change_cutoff_attack()", "change_cutoff_decay()",
217          "change_cutoff_sustain()", "change_cutoff_release()",
218          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
219          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
220          "change_pan_time()", "fade_in()", "fade_out()", "change_play_pos()".
221        - Fixed built-in function "change_play_pos()" not having accepted metric
222          prefixes at all.
223        - Fixed the following built-in functions having misinterpreted values given
224          with unit type (for their 2nd argument) as if they were relative values
225          (that is as if they were passed without a unit type): "change_attack()",
226          "change_decay()", "change_release()", "change_cutoff_attack()",
227          "change_cutoff_decay()", "change_cutoff_release()".
228        - Fixed the following built-in functions having applied completely wrong
229          'final' values: "change_sustain()", "change_cutoff_sustain()" (since the
230          respective EGs being their modulation sink assume uint data type with
231          value range 0..1000 instead of 0.0..1.0.
232        - Added individual parse-time checks of function arguments for the following
233          built-in functions: "play_note()", "note_off()", "set_event_mark()",
234          "delete_event_mark()", "by_marks()", "change_cutoff()", "change_attack()",
235          "change_decay()", "change_release()", "change_cutoff_attack()",
236          "change_cutoff_decay()", "change_cutoff_release()",
237          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
238          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()" and
239          "change_pan_time()".
240        - Don't abort function call if unit type was used and at the same time
241          'final' operator was omitted for the primary value argument of the
242          following built-in functions: "change_cutoff()", "change_attack()",
243          "change_decay()", "change_release()", "change_cutoff_attack()",
244          "change_cutoff_decay()", "change_cutoff_release()",
245          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
246          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
247          "change_pan_time()", instead imply 'final'ness at runtime and raise an
248          appropriate parser warning at parse time.
249        - Added built-in real number functions "round()", "ceil()", "floor()",
250          "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()", "sin()",
251          "cos()", "tan()", "asin()", "acos()", "atan()".
252        - Added built-in script real number constant "~NI_MATH_PI".
253        - Added built-in script real number constant "~NI_MATH_E".
254        - NKSP language: Allow unary '+' operator.
255        - Added built-in script functions "msb()" and "lsb()".
256        - NKSP language: Added support for RPN event handler
257          ("on rpn ... end on" in instrument scripts).
258        - NKSP language: Added support for NRPN event handler
259          ("on nrpn ... end on" in instrument scripts).
260        - Added built-in read-only variables "$RPN_ADDRESS" and "$RPN_VALUE" which
261          may be read from the new RPN/NRPN script handlers to get the (N)RPN
262          parameter that had been changed and its new value.
263        - Added built-in const variables "$NI_CB_TYPE_RPN" and "$NI_CB_TYPE_NRPN"
264          which are identifying the new (N)RPN handlers as such at script runtime.
265        - Implemented built-in script function "set_rpn()".
266        - Implemented built-in script function "set_nrpn()".
267        - Fix: built-in functions returning an array type were broken and caused a
268          crash when the built-in function's (supposed to be array) result value was
269          used by the script VM.
270        - Removed upper value constraint for 2nd argument of built-in functions
271          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
272          "change_pitch_lfo_freq()","change_reso()", "change_cutoff()",
273          "change_amp_lfo_depth()", "change_cutoff_lfo_depth()" and
274          "change_pitch_lfo_depth()", to allow e.g. passing value 2000000 to double
275          the LFO frequency / resonance / cutoff frequency.
276        - Reduced code involved for parsing NKSP variable declarations by using 2
277          generalized grammar rules with optional components (i.e. optional value
278          assignment and optional variable qualifiers) instead of previous linear
279          combinations of grammar rules, which also fixes some edge case.
280        - NKSP language parser: track code block locations also by a) raw byte
281          position in NKSP source code string and b) length of that code block in
282          bytes (along to the already existing code block tracking by line/column);
283          and added appropriate new members to public C++ API classes like
284          'firstByte' and 'lengthBytes' to class VMSourceToken and struct CodeBlock.
285        - NKSP language: Added support for 'patch' variable qualifier (capture their
286          locations and allow replacement of their assignment expression via VM C++
287          API).
288        - Fixed incorrect EG times if standard measuring unit was passed to built-in
289          functions "change_attack()", "change_decay()" or "change_release()".
290        - Fixed intermediate function result values never having reflected any
291          standard measuring unit type.
292        - Fixed re-entrant issue with function calls which caused wrong result
293          values if the same function was called multiple times in a term
294          (specifically if metric prefixes were used).
295        - NKSP language: Just throw a warning, not an error if an array variable of
296          size zero was declared.
297        - NKSP language: Allow omitting explicit array size on array variable
298          declaration if combined with immediate value assignment
299          (e.g. declare %foo[] := ( 1, 2, 3 ) ).
300        - NKSP language: emit warning if an array variable was declared with bigger
301          array size than amount of initial values been assigned, and initialize the
302          missing array elements with zero in this case.
303        - Fixed built-in NKSP exit() function to behave as return statement.
304        - NKSP parser: Fixed crash if unary '-' operator was used on a non-number
305          data type.
306        - NKSP VM: Fixed the "release" handler being executed too often under
307          certain situations if polyphonic data was passed from "note" handler to
308          "release" handler.
309        - Fixed memory leak in NKSP parser: string tokens were allocated as C
310          strings and never freed.
311        - Fixed incorrect polyphonic data transfer from wrong note handler to
312          release handler; which also fixes no release handler being executed
313          sometimes, and due to the latter it also fixes potential crashes as some
314          polyphonic script events were never released and the engine hence was
315          running out of free script events.
316        - Fixed crash when handling array results of built-in functions
317          (e.g. "num_elements(by_marks($MARK_1)").
318        - NKSP VM: Fixed dead note events not been removed from user's event groups
319          (i.e. causing incorrect behaviour of built-in NKSP functions by_marks()
320          and set_event_mark() after max. size of event group list was exhausted).
321    
322    * test cases:    * test cases:
323      - Fixed compiler errors in test cases.      - Fixed compiler errors in test cases.
# Line 143  Version SVN trunk (?) Line 336  Version SVN trunk (?)
336        'final' operator usage cases.        'final' operator usage cases.
337      - Added NKSP test cases for (floating point tolerance aware) real number      - Added NKSP test cases for (floating point tolerance aware) real number
338        equalness / unequalness comparison.        equalness / unequalness comparison.
339        - Added NKSP int array and real array tests for value assignment and
340          initialization of arrays.
341        - Added NKSP test cases for built-in functions "round()", "ceil()",
342          "floor()", "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()",

345        - Added NKSP test cases for core built-in variables.
346        - Added thorough NKSP test cases for variable declarations.
347    
348      * GigaStudio/Gigasampler format engine:
349        - LFOTriangleIntMath and LFOTriangleIntAbsMath: Fixed FlipPhase=true
350          behaviour for start_level_mid.
351        - Changed LFO start levels: LFO1 and LFO2 both to mid, LFO3 to max. start
352          level (see discussion "GigaStudio LFO compatibility" on mailing list
353          from 2019-09-26 for details).
354        - Changed default wave form for all 3 LFOs to sine (instead of triangle;
355          see discussion "GigaStudio LFO compatibility" on mailing list from
356          2019-09-26 for details).
357        - Format extension: Added support for different LFO wave forms (currently
358          either sine [default], triangle, saw or square).
359        - Format extension: Added support for LFO phase displacement (0°..360°).
360        - Format extension: Added support for flipping LFO polarity on LFO 3
361          (in the original gig format this was only available for LFO 1 and LFO 2).
362        - Format extension: Support for additional filter types:
363          lowpass 1/2/4/6-pole, highpass 1/2/4/6-pole, bandpass 2-pole,
364          bandreject 2-pole.
365        - Fixd potential crash with polynomial interpolator and max. pitch.
366        - If minimum cutoff is defined, remap cutoff controller CC values to really
367          span the entire possible cutoff range (and avoiding a dead controller
368          zone).
369        - Implemented support for loading instrument scripts with 'patch' variables
370          (by patching these script variables with potentially overridden ones by
371          gig Instrument).
372    
373      * SFZ format engine:
374        - Fixed support for regions with loccN/hiccN conditions on more than one
375          MIDI controller.
376        - Fixed internal opcode 'xfin_hivel' falsely being set by user opcode
377          'xfin_lovel' (patch by Christian Czezatke).
378    
379      * Benchmarks:
380        - Fixed benchmarks/triang.cpp falsely having favoured "int math abs"
381          algorithm (since result of 2nd run was not accumulated).
382        - Added benchmark for saw wave (benchmarks/saw.cpp).
383        - Added benchmark for sine wave (benchmarks/sine.cpp).
384        - Added benchmark for square wave (benchmarks/square.cpp).
385        - Increased amount of benchmarks runs by factor 6 to achieve benchmark times
386          which are large enough on modern systems.
