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.

144      - Added individual parse time checks of arguments to be passed to built-in      - Added individual parse time checks of arguments to be passed to built-in
145        functions "random()", "inc()", "dec()", "in_range()", "min()", "max()",        functions "random()", "inc()", "dec()", "in_range()", "min()", "max()",
146        "array_equal()" and "search()" specific for their individual purposes.        "array_equal()" and "search()" specific for their individual purposes.
147        - NKSP VM refactoring: Renamed all methods, functions and classes matching
148          pattern *ScalarNumber* to simply *Number* (that is i.e. classes
149          VMScalarNumberExpr -> VMNumberExpr, ScalarNumberExpr -> NumberExpr,
150          ScalarNumberVariable -> NumberVariable, ScalarNumberBinaryOp ->
151          NumberBinaryOp, VMScalarNumberResultFunction -> VMNumberResultFunction,
152          method VMExpr::asScalarNumberExpr() -> VMExpr::asNumber(), function
153          isScalarNumber() -> isNumber()).
154        - NKSP VM API: Added 4 overridden methods to class VMNumberExpr:
155          evalCastInt(MetricPrefix_t), evalCastInt(MetricPrefix_t,MetricPrefix_t),
156          evalCastReal(MetricPrefix_t), evalCastReal(MetricPrefix_t,MetricPrefix_t)
157          as convenient methods for automatically converting values to expected
158          metric value basis.
159        - Built-in function "wait()" accepts now both integers and real numbers as
160          argument.
161        - NKSP VM API cleanup: Get rid of legacy method
162          VMFunction::argType(vmint iArg) which was already superseded by its new
163          replacement VMFunction::acceptsArgType(vmint iArg, ExprType_t type).
164        - NKSP parser: if wrong argument type was passed to a built-in function and
165          that built-in function accepts more than one data type for the argument,
166          then show all supported data types as parser error message.
167        - Built-in function "play_note()" accepts now real numbers and seconds as
168          unit type as well for its 3rd and 4th function arguments.
169        - The following built-in functions accept now real numbers as well for their
170          2nd function argument: "change_vol()", "change_tune()", "change_cutoff()",
171          "change_attack()", "change_decay()", "change_release()",
172          "change_sustain()", "change_cutoff_attack()", "change_cutoff_decay()",
173          "change_cutoff_sustain()", "change_cutoff_release()",
174          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
175          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
176          "change_pan_time()", "fade_in()", "fade_out()", "change_play_pos()".
177        - Fixed built-in function "change_play_pos()" not having accepted metric
178          prefixes at all.
179        - Fixed the following built-in functions having misinterpreted values given
180          with unit type (for their 2nd argument) as if they were relative values
181          (that is as if they were passed without a unit type): "change_attack()",
182          "change_decay()", "change_release()", "change_cutoff_attack()",
183          "change_cutoff_decay()", "change_cutoff_release()".
184        - Fixed the following built-in functions having applied completely wrong
185          'final' values: "change_sustain()", "change_cutoff_sustain()" (since the
186          respective EGs being their modulation sink assume uint data type with
187          value range 0..1000 instead of 0.0..1.0.
188        - Added individual parse-time checks of function arguments for the following
189          built-in functions: "play_note()", "note_off()", "set_event_mark()",
190          "delete_event_mark()", "by_marks()", "change_cutoff()", "change_attack()",
191          "change_decay()", "change_release()", "change_cutoff_attack()",
192          "change_cutoff_decay()", "change_cutoff_release()",
193          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
194          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()" and
195          "change_pan_time()".
196        - Don't abort function call if unit type was used and at the same time
197          'final' operator was omitted for the primary value argument of the
198          following built-in functions: "change_cutoff()", "change_attack()",
199          "change_decay()", "change_release()", "change_cutoff_attack()",
200          "change_cutoff_decay()", "change_cutoff_release()",
201          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
202          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
203          "change_pan_time()", instead imply 'final'ness at runtime and raise an
204          appropriate parser warning at parse time.
205        - Added built-in real number functions "round()", "ceil()", "floor()",
206          "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()", "sin()",
207          "cos()", "tan()", "asin()", "acos()", "atan()".
208        - Added built-in script real number constant "~NI_MATH_PI".
209        - Added built-in script real number constant "~NI_MATH_E".
210        - NKSP language: Allow unary '+' operator.
211        - Added built-in script functions "msb()" and "lsb()".
212

230        - Added NKSP int array and real array tests for value assignment and
231          initialization of arrays.
232        - Added NKSP test cases for built-in functions "round()", "ceil()",
233          "floor()", "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()",
234          "sin()", "cos()", "tan()", "asin()", "acos()", "atan()".
235        - Added NKSP test cases for unary '+' operator.
236    
237      * GigaStudio/Gigasampler format engine:
238        - LFOTriangleIntMath and LFOTriangleIntAbsMath: Fixed FlipPhase=true
239          behaviour for start_level_mid.
240        - Changed LFO start levels: LFO1 and LFO2 both to mid, LFO3 to max. start
241          level (see discussion "GigaStudio LFO compatibility" on mailing list
242          from 2019-09-26 for details).
243        - Changed default wave form for all 3 LFOs to sine (instead of triangle;
244          see discussion "GigaStudio LFO compatibility" on mailing list from
245          2019-09-26 for details).
246        - Format extension: Added support for different LFO wave forms (currently
247          either sine [default], triangle, saw or square).
248        - Format extension: Added support for LFO phase displacement (0°..360°).
249        - Format extension: Added support for flipping LFO polarity on LFO 3
250          (in the original gig format this was only available for LFO 1 and LFO 2).
251        - Format extension: Support for additional filter types:
252          lowpass 1/2/4/6-pole, highpass 1/2/4/6-pole, bandpass 2-pole,
253          bandreject 2-pole.
254    
255      * SFZ format engine:
256        - Fixed support for regions with loccN/hiccN conditions on more than one
257          MIDI controller.
258    
259      * Benchmarks:
260        - Fixed benchmarks/triang.cpp falsely having favoured "int math abs"
261          algorithm (since result of 2nd run was not accumulated).
262        - Added benchmark for saw wave (benchmarks/saw.cpp).
263        - Added benchmark for sine wave (benchmarks/sine.cpp).
264        - Added benchmark for square wave (benchmarks/square.cpp).
265        - Increased amount of benchmarks runs by factor 6 to achieve benchmark times
266          which are large enough on modern systems.
