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

71    * Real-time instrument scripts:    * Real-time instrument scripts:
72      - Added method ScriptVM::setExitResultEnabled() which allows to      - Added method ScriptVM::setExitResultEnabled() which allows to
# Line 181  Version SVN trunk (?) Line 238  Version SVN trunk (?)
238        "cos()", "tan()", "asin()", "acos()", "atan()".        "cos()", "tan()", "asin()", "acos()", "atan()".
239      - Added built-in script real number constant "~NI_MATH_PI".      - Added built-in script real number constant "~NI_MATH_PI".
240      - Added built-in script real number constant "~NI_MATH_E".      - Added built-in script real number constant "~NI_MATH_E".
241        - NKSP language: Allow unary '+' operator.
242        - Added built-in script functions "msb()" and "lsb()".
243        - NKSP language: Added support for RPN event handler
244          ("on rpn ... end on" in instrument scripts).
245        - NKSP language: Added support for NRPN event handler
246          ("on nrpn ... end on" in instrument scripts).
247        - Added built-in read-only variables "$RPN_ADDRESS" and "$RPN_VALUE" which
248          may be read from the new RPN/NRPN script handlers to get the (N)RPN
249          parameter that had been changed and its new value.
250        - Added built-in const variables "$NI_CB_TYPE_RPN" and "$NI_CB_TYPE_NRPN"
251          which are identifying the new (N)RPN handlers as such at script runtime.
252        - Implemented built-in script function "set_rpn()".
253        - Implemented built-in script function "set_nrpn()".
254        - Fix: built-in functions returning an array type were broken and caused a
255          crash when the built-in function's (supposed to be array) result value was
256          used by the script VM.
257        - Removed upper value constraint for 2nd argument of built-in functions
258          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
259          "change_pitch_lfo_freq()","change_reso()", "change_cutoff()",
260          "change_amp_lfo_depth()", "change_cutoff_lfo_depth()" and
261          "change_pitch_lfo_depth()", to allow e.g. passing value 2000000 to double
262          the LFO frequency / resonance / cutoff frequency.
263        - Reduced code involved for parsing NKSP variable declarations by using 2
264          generalized grammar rules with optional components (i.e. optional value
265          assignment and optional variable qualifiers) instead of previous linear
266          combinations of grammar rules, which also fixes some edge case.
267        - NKSP language parser: track code block locations also by a) raw byte
268          position in NKSP source code string and b) length of that code block in
269          bytes (along to the already existing code block tracking by line/column);
270          and added appropriate new members to public C++ API classes like
271          'firstByte' and 'lengthBytes' to class VMSourceToken and struct CodeBlock.
272        - NKSP language: Added support for 'patch' variable qualifier (capture their
273          locations and allow replacement of their assignment expression via VM C++
274          API).
275        - Fixed incorrect EG times if standard measuring unit was passed to built-in
276          functions "change_attack()", "change_decay()" or "change_release()".
277        - Fixed intermediate function result values never having reflected any
278          standard measuring unit type.
279        - Fixed re-entrant issue with function calls which caused wrong result
280          values if the same function was called multiple times in a term
281          (specifically if metric prefixes were used).
282    
283    * test cases:    * test cases:
284      - Fixed compiler errors in test cases.      - Fixed compiler errors in test cases.

302      - Added NKSP test cases for built-in functions "round()", "ceil()",      - Added NKSP test cases for built-in functions "round()", "ceil()",
303        "floor()", "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()",        "floor()", "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()",
304        "sin()", "cos()", "tan()", "asin()", "acos()", "atan()".        "sin()", "cos()", "tan()", "asin()", "acos()", "atan()".
305        - Added NKSP test cases for unary '+' operator.
306        - Added NKSP test cases for core built-in variables.
307        - Added thorough NKSP test cases for variable declarations.
308    
309      * GigaStudio/Gigasampler format engine:
310        - LFOTriangleIntMath and LFOTriangleIntAbsMath: Fixed FlipPhase=true
311          behaviour for start_level_mid.
312        - Changed LFO start levels: LFO1 and LFO2 both to mid, LFO3 to max. start
313          level (see discussion "GigaStudio LFO compatibility" on mailing list
314          from 2019-09-26 for details).
315        - Changed default wave form for all 3 LFOs to sine (instead of triangle;
316          see discussion "GigaStudio LFO compatibility" on mailing list from
317          2019-09-26 for details).
318        - Format extension: Added support for different LFO wave forms (currently
319          either sine [default], triangle, saw or square).
320        - Format extension: Added support for LFO phase displacement (0°..360°).
321        - Format extension: Added support for flipping LFO polarity on LFO 3
322          (in the original gig format this was only available for LFO 1 and LFO 2).
323        - Format extension: Support for additional filter types:
324          lowpass 1/2/4/6-pole, highpass 1/2/4/6-pole, bandpass 2-pole,
325          bandreject 2-pole.
326        - Fixd potential crash with polynomial interpolator and max. pitch.
327        - If minimum cutoff is defined, remap cutoff controller CC values to really
328          span the entire possible cutoff range (and avoiding a dead controller
329          zone).
330        - Implemented support for loading instrument scripts with 'patch' variables
331          (by patching these script variables with potentially overridden ones by
332          gig Instrument).
333    
334      * SFZ format engine:
335        - Fixed support for regions with loccN/hiccN conditions on more than one
336          MIDI controller.
337    
338      * Benchmarks:
339        - Fixed benchmarks/triang.cpp falsely having favoured "int math abs"
340          algorithm (since result of 2nd run was not accumulated).
341        - Added benchmark for saw wave (benchmarks/saw.cpp).
342        - Added benchmark for sine wave (benchmarks/sine.cpp).
343        - Added benchmark for square wave (benchmarks/square.cpp).
344        - Increased amount of benchmarks runs by factor 6 to achieve benchmark times
345          which are large enough on modern systems.
