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    
46    * Real-time instrument scripts:    * Real-time instrument scripts:
47      - Added method ScriptVM::setExitResultEnabled() which allows to      - Added method ScriptVM::setExitResultEnabled() which allows to

210        appropriate parser warning at parse time.        appropriate parser warning at parse time.
211        - Added built-in real number functions "round()", "ceil()", "floor()",
212          "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()", "sin()",
213          "cos()", "tan()", "asin()", "acos()", "atan()".
214        - Added built-in script real number constant "~NI_MATH_PI".
215        - Added built-in script real number constant "~NI_MATH_E".
216        - NKSP language: Allow unary '+' operator.
217        - Added built-in script functions "msb()" and "lsb()".
218        - NKSP language: Added support for RPN event handler
219          ("on rpn ... end on" in instrument scripts).
220        - NKSP language: Added support for NRPN event handler
221          ("on nrpn ... end on" in instrument scripts).
222        - Added built-in read-only variables "$RPN_ADDRESS" and "$RPN_VALUE" which
223          may be read from the new RPN/NRPN script handlers to get the (N)RPN
224          parameter that had been changed and its new value.
225        - Added built-in const variables "$NI_CB_TYPE_RPN" and "$NI_CB_TYPE_NRPN"
226          which are identifying the new (N)RPN handlers as such at script runtime.
227        - Implemented built-in script function "set_rpn()".
228        - Implemented built-in script function "set_nrpn()".
229    
230    * test cases:    * test cases:

254    
255      * GigaStudio/Gigasampler format engine:
256        - LFOTriangleIntMath and LFOTriangleIntAbsMath: Fixed FlipPhase=true
257          behaviour for start_level_mid.
258        - Changed LFO start levels: LFO1 and LFO2 both to mid, LFO3 to max. start
259          level (see discussion "GigaStudio LFO compatibility" on mailing list
260          from 2019-09-26 for details).
261        - Changed default wave form for all 3 LFOs to sine (instead of triangle;
262          see discussion "GigaStudio LFO compatibility" on mailing list from
263          2019-09-26 for details).
264        - Format extension: Added support for different LFO wave forms (currently
265          either sine [default], triangle, saw or square).
266        - Format extension: Added support for LFO phase displacement (0°..360°).
267        - Format extension: Added support for flipping LFO polarity on LFO 3
268          (in the original gig format this was only available for LFO 1 and LFO 2).
269        - Format extension: Support for additional filter types:
270          lowpass 1/2/4/6-pole, highpass 1/2/4/6-pole, bandpass 2-pole,
271          bandreject 2-pole.
272    
273      * SFZ format engine:
274        - Fixed support for regions with loccN/hiccN conditions on more than one
275          MIDI controller.
276    
277      * Benchmarks:
278        - Fixed benchmarks/triang.cpp falsely having favoured "int math abs"
279          algorithm (since result of 2nd run was not accumulated).
280        - Added benchmark for saw wave (benchmarks/saw.cpp).
281        - Added benchmark for sine wave (benchmarks/sine.cpp).
282        - Added benchmark for square wave (benchmarks/square.cpp).
283        - Increased amount of benchmarks runs by factor 6 to achieve benchmark times
284          which are large enough on modern systems.
