1  Version SVN trunk (?)  Version SVN trunk (?)
2    
3      * general changes:
4        - AbstractEngineChannel: fixed CCs not being forwarded to all
5          VirtualMIDIDevices.
6    
7      * Real-time instrument scripts:
8        - Fix: Do not share compiled instrument scripts among multiple engine
9          channels (sampler parts) as this can lead to crashes and would allow the
10          same global script variables to be accessible from multiple engine
11          channels which would not be the expected behaviour by instrument script
12          authors.
13    
14      * GigaStudio/Gigasampler format engine:
15        - Use libgig's new IO-per-thread feature to avoid file I/O concurrency
16          issues with .gig file.
17        - Use libgig's new method gig::File::GetSample() with method
18          gig::File::CountSamples() instead of now deprecated
19          gig::File::GetFirstSample() / gig::File::GetNextSample() pair.
20        - Use libgig's new method gig::Instrument::GetRegionAt() with method
21          gig::Instrument:CountRegions() instead of now deprecated
22          gig::Instrument::GetFirstRegion() / gig::Instrument::GetNextRegion() pair.
23        - Use libgig's gig::File::GetInstrument() method with method
24          gig::File::CountInstruments() instead of now deprecated
25          gig::File::GetFirstInstrument() / gig::File::GetNextInstrument() pair.
26    
27      * MIDI driver:
28        - VirtualMidiDevice: added method Reset() which is e.g. intended to be used
29          in "panic" / MIDI "all sound off" / MIDI "all note off" situations.
30        - VirtualMidiDevice: release all notes on MIDI CC #120 and CC #123.
31    
32    Version 2.2.0 (9 May 2021)
33    
34      * general changes:
35        - Fixed compiler error in Pool.h.
36        - Require C++14 compiler support.
37        - Autoconf: Added m4/ax_cxx_compile_stdcxx.m4 macro which is used
38          for checking in configure for C++14 support (as mandatory
39          requirement) and automatically adds compiler argument if required
40          (e.g. -std=C++14).
41        - RTMath: Implemented floating point comparison methods
42          fEqual32(float,float) and fEqual64(double,double) which take the
43          expected floating point tolerances into account.
44        - Added public API C++ class "LFO", which is a cluster class encapsulating
45          all the sampler's LFO implementations to be used by 3rd party applications
46          (e.g. by Gigedit).
47        - Added int math square LFO implementation.
48        - Added int math saw LFO implementation.
49        - Added numeric complex nr sine LFO implementation.
50        - Marked class LFOTriangleDiHarmonic as deprecated
51          (will be removed in future).
52        - Added LFOAll.h which includes all LFO implementation's header files.
53        - Refactored LFO class names and their file names (PulseLFO -> LFOPulse,
54          LFOSawIntMath -> LFOSawIntMathNew, SawLFO -> LFOSawIntMathOld,
55          SineLFO -> LFOSineBuiltinFn, LFOSine -> LFOSineNumericComplexNr,
56          SquareLFO -> LFOSquarePulse and separated the latter to its own header
57          file).
58        - Renamed type LFOSigned -> LFOTriangleSigned.
59        - Renamed type LFOUnsigned -> LFOTriangleUnsigned.
60        - Using now cubic interpolation as resampling algorithm by default; and
61          linear interpolation is deprecated now.
62        - Event:Init(): memset() entire Event::Param union to zero instead of trying
63          to do that for its individual members; the latter became error prone due
64          to the union's growing complexity meanwhile.
65        - EngineChannel: Overhaul of RPN/NRPN related methods: Added new
66          *Rpn*Parameter*() methods as replacement for previous *Rpn*Controller*()
67          methods and marked the old ones as deprecated; and likewise added new
68          *Nrpn*Parameter*() methods as replacement for previous *Nrpn*Controller*()
69          methods and marked those old ones deprecated as well.
70        - Added support for MIDI CC #38 (data entry LSB): this allows higher value
71          resolution for certain (e.g. hard coded) RPN and NRPN parameters.
72        - Implemented support for compressed RPN/NRPN message sequences (that is to
73          allow processing MIDI data entry messages without always having to be
74          preceded strictly by RPN/NRPN parameter selection messages on each value
75          change).
76        - Added support for MIDI CC #96 (data increment) and MIDI CC #97 (data
77          decrement).
78        - Added support for 'null function RPN/NRPN' (which is RPN/NRPN parameter
79          MSB=127 and LSB=127) and which is disabling subsequent data
80          entry/increment/decrement CC messages.
81        - Fixed crash when editing key groups (a.k.a. exclusive groups) with an
82          instrument editor.
83        - Fixed playing noise at the end of a disk stream under certain conditions.
84        - Fixed potential crash with high pitch at end of RAM playback.
85        - Added configure checks whether C++ compiler supports so called
86          'designated initializers'.
87        - Added global backtraceAsString() function for debugging purposes
88          (POSIX systems only, no Windows implementation yet).
89        - Thread class: Added new methods pushCancelable(), popCancelable(), name(),
90          nameOfCaller() and setNameOfCaller().
91        - configure: Always check for availability of pthread_testcancel() and use
92          it if so (previously it was only used if explicitly enabled by configure
93          option).
94        - Thread class: raise compiler warning if pthread_testcancel() is not
95          available, because it can lead to deadlocks.
96        - Mutex class: Implemented optional bug detection and deadlock debugging
97          features.
98        - Ref<> class is now thread safe (as lock-free and wait-free
99          implementation).
100        - Fixed compilation error with Bison >= 3.6.0.
101        - Fixed rare crash when switching between instruments that had instrument
102          scripts loaded.
103        - Allow EffectChain::InsertEffect() as alternative to
104          EffectChain::AppendEffect() (i.e. with index equal to current chain size).
105        - ConstCapacityArray class: Fixed bug in remove() method.
106        - Fixed crash on certain MIDI RPN and NRPN messages that occurred if no
107          real-time instrument script was loaded.
108    
109      * Real-time instrument scripts:
110        - Added method ScriptVM::setExitResultEnabled() which allows to
111          explicitly enable the built-in exit() function to optionally accept
112          one function argument; the value of the passed exit() function
113          argument will then become available by calling
114          VMExecContext::exitResult() after script execution.
115        - 64 bit support for NKSP integer scripts variables (declare $foo).
116        - Variable names, function names and preprocessor condition names must start
117          with a regular character (a-z or A-Z); starting them with a digit or
118          underscore is not allowed.
119        - NKSP parser fix: equal comparison operator "=" and not equal comparison
120          operator "#" must only accept integer operands.
121        - NKSP language: Implemented support for standard units like Hertz, seconds,
122          Bel including support for metric unit prefixes; so one can now e.g.
123          conveniently use numbers in scripts like "5us" meaning "5 microseconds",
124          or e.g. "12kHz" meaning "12 kilo Hertz", or e.g. "-14mdB" meaning
125          "minus 14 Millidecibel", or e.g. "28c" meaning "28 cents" (for tuning).
126        - NKSP language: Introduced "final" operator "!" which is specifically
127          intended for synthesis parameter values to denote that the synthesis
128          parameter value is intended to be the "final" value for that synthesis
129          parameter that should explicitly be used by the engine and thus causing
130          the sampler engine to ignore all other modulation sources for the same
131          synthesis parameter (like e.g. LFO, EG); by simply prefixing a value,
132          variable or formula with this new "!" operator the expression is marked as
133          being "final".
134        - NKSP script editor API: Added support for detecting standard unit tokens
135          and their potential metric prefix token.
136        - NKSP language: Added support for NKSP real number literals and
137          arithmetic operations on them (e.g. "(3.9 + 2.9) / 12.3 - 42.0").
138        - NKSP language: Added support for NKSP real number (floating point) script
139          variables (declare ~foo).
140        - NKSP language: Added support for NKSP real number (floating point) array
141          script variables (declare ?foo[]).
142        - Built-in script function "message()" accepts now real number argument as
143          well.
144        - Added built-in script function "real_to_int()" and its short hand form
145          "int()" for casting from real number to integer in NKSP scripts.
146        - Added built-in script function "int_to_real()" and its short hand form
147          "real()" for casting from integer to real number in NKSP scripts.
148        - Allow built-in exit() function to potentially accept real number type
149          argument as well.
150        - Built-in script functions may have a different return type depending on
151          the arguments passed to the function.
152        - Built-in script function "abs()" optionally accepts and returns real
153          number.
154        - Built-in script functions "min()" and "max()" optionally accept real
155          number arguments and return real number as result in that case.
156        - NKSP VM API: Allow units and 'final'ness to be returned as result from
157          built-in functions (added methods VMFunction::returnUnitType() and
158          VMFunction::returnsFinal() for that purpose which must be implemented by
159          built-in function implementations).
160        - NKSP language: Allow metric unit prefixes of numeric scalar and array
161          variables to be changed freely at runtime (unlike unit types like Hz etc.
162          which are still sticky, parse-time features of variables which cannot be
163          changed at runtime for the intentional sake of determinism).
164        - NKSP language: 'final' values are prohibited for array variables for now
165          (attempt causes a parsers error).
166        - NKSP language: expressions with unit types (e.g. Hz) are prohibited for
167          conditions of runtime control structures like if(), while(), select()
168          (attempt causes a parser error).
169        - NKSP VM API: Allow built-in functions to perform their own, individual
170          parse time checks of arguments going to be passed to the function at
171          runtime (added method VMFunction::checkArgs() for that purpose).
172        - NKSP language: raise parser warning if only one operand of binary
173          operators (like logical 'or' comparison) contain a 'final' value (because
174          it would always yield in a 'final' result in such cases).
175        - NKSP language: Allow comparison (=, #, <, >, <=, >=) of values with
176          different metric unit prefixes, which will behave as expected (e.g.
177          result of expression '1000us < 2ms' is true).
178        - NKSP language: Allow adding values with different metric unit prefixes
179          (e.g. result of expression '100Hz + 5kHz' is '5100Hz').
180        - NKSP language: Allow subtracting values with different metric unit
181          prefixes (e.g. result of expression '1ms - 20us' is '980us').
182        - NKSP language: Allow multiplying with any metric unit prefixes
183          (e.g. result of expression '2k * 3ms' is '6s'), however multiplications
184          with unit types on both sides (e.g. '2s * 2s') is still prohibited since
185          we don't have any considerable practical use for a term like '4s^2'
186          (hence any attempt multiplying two unit types still causes parser error).
187        - NKSP language: Allow dividing by any metric unit prefixes and allow
188          division of same unit type on both sides (e.g. expression '8kHz / 1000Hz'
189          yields in unit free result '8'). So this is now a way to cast units away
190          e.g. for passing the result to other expressions, certain function calls
191          or variables which are not accepting any units (or that specific unit).
192        - NKSP language: integer arrays and real number arrays can now be converted
193          to strings (e.g. for dumping their content with message() calls for
194          script debugging purposes).
195        - NKSP language: expressions and variables with units are now correctly
196          casted to strings (e.g. with message() calls).
197        - NKSP language: comparing real numbers for equalness (e.g. '~foo = 3.1') or
198          unequalness (e.g. '~foo # 3.1') is now less strict and takes the expected
199          floating point tolerances into account.
200        - NKSP VM API: Added methods VMScalarNumberExpr::evalCastInt() and
201          VMScalarNumberExpr::evalCastReal().
202        - NKSP VM API: Added base class 'VMNumberArrayExpr' for classes
203          'VMIntArrayExpr' and 'VMRealArrayExpr'.
204        - NKSP VM API: replaced all unitPrefix() (parse time) methods by
205          unitFactor() (runtime) methods.
206        - Built-in function "exit()" supports now returning units and 'final'ness
207          for test cases.
208        - The following built-in functions support now units as well: "abs()",
209          "random()", "inc()", "dec()", "in_range()", "min()", "max()",
210          "real_to_int()", "int()", "int_to_real()" and "real()".
211        - Built-in functions "array_equal()", "search()" and "sort()" support now
212          real number arrays (correctly) as well.
213        - Added individual parse time checks of arguments to be passed to built-in
214          functions "random()", "inc()", "dec()", "in_range()", "min()", "max()",
215          "array_equal()" and "search()" specific for their individual purposes.
216        - NKSP VM refactoring: Renamed all methods, functions and classes matching
217          pattern *ScalarNumber* to simply *Number* (that is i.e. classes
218          VMScalarNumberExpr -> VMNumberExpr, ScalarNumberExpr -> NumberExpr,
219          ScalarNumberVariable -> NumberVariable, ScalarNumberBinaryOp ->
220          NumberBinaryOp, VMScalarNumberResultFunction -> VMNumberResultFunction,
221          method VMExpr::asScalarNumberExpr() -> VMExpr::asNumber(), function
222          isScalarNumber() -> isNumber()).
223        - NKSP VM API: Added 4 overridden methods to class VMNumberExpr:
224          evalCastInt(MetricPrefix_t), evalCastInt(MetricPrefix_t,MetricPrefix_t),
225          evalCastReal(MetricPrefix_t), evalCastReal(MetricPrefix_t,MetricPrefix_t)
226          as convenient methods for automatically converting values to expected
227          metric value basis.
228        - Built-in function "wait()" accepts now both integers and real numbers as
229          argument.
230        - NKSP VM API cleanup: Get rid of legacy method
231          VMFunction::argType(vmint iArg) which was already superseded by its new
232          replacement VMFunction::acceptsArgType(vmint iArg, ExprType_t type).
233        - NKSP parser: if wrong argument type was passed to a built-in function and
234          that built-in function accepts more than one data type for the argument,
235          then show all supported data types as parser error message.
236        - Built-in function "play_note()" accepts now real numbers and seconds as
237          unit type as well for its 3rd and 4th function arguments.
238        - The following built-in functions accept now real numbers as well for their
239          2nd function argument: "change_vol()", "change_tune()", "change_cutoff()",
240          "change_attack()", "change_decay()", "change_release()",
241          "change_sustain()", "change_cutoff_attack()", "change_cutoff_decay()",
242          "change_cutoff_sustain()", "change_cutoff_release()",
243          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
244          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
245          "change_pan_time()", "fade_in()", "fade_out()", "change_play_pos()".
246        - Fixed built-in function "change_play_pos()" not having accepted metric
247          prefixes at all.
248        - Fixed the following built-in functions having misinterpreted values given
249          with unit type (for their 2nd argument) as if they were relative values
250          (that is as if they were passed without a unit type): "change_attack()",
251          "change_decay()", "change_release()", "change_cutoff_attack()",
252          "change_cutoff_decay()", "change_cutoff_release()".
253        - Fixed the following built-in functions having applied completely wrong
254          'final' values: "change_sustain()", "change_cutoff_sustain()" (since the
255          respective EGs being their modulation sink assume uint data type with
256          value range 0..1000 instead of 0.0..1.0.
257        - Added individual parse-time checks of function arguments for the following
258          built-in functions: "play_note()", "note_off()", "set_event_mark()",
259          "delete_event_mark()", "by_marks()", "change_cutoff()", "change_attack()",
260          "change_decay()", "change_release()", "change_cutoff_attack()",
261          "change_cutoff_decay()", "change_cutoff_release()",
262          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
263          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()" and
264          "change_pan_time()".
265        - Don't abort function call if unit type was used and at the same time
266          'final' operator was omitted for the primary value argument of the
267          following built-in functions: "change_cutoff()", "change_attack()",
268          "change_decay()", "change_release()", "change_cutoff_attack()",
269          "change_cutoff_decay()", "change_cutoff_release()",
270          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
271          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
272          "change_pan_time()", instead imply 'final'ness at runtime and raise an
273          appropriate parser warning at parse time.
274        - Added built-in real number functions "round()", "ceil()", "floor()",
275          "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()", "sin()",
276          "cos()", "tan()", "asin()", "acos()", "atan()".
277        - Added built-in script real number constant "~NI_MATH_PI".
278        - Added built-in script real number constant "~NI_MATH_E".
279        - NKSP language: Allow unary '+' operator.
280        - Added built-in script functions "msb()" and "lsb()".
281        - NKSP language: Added support for RPN event handler
282          ("on rpn ... end on" in instrument scripts).
283        - NKSP language: Added support for NRPN event handler
284          ("on nrpn ... end on" in instrument scripts).
285        - Added built-in read-only variables "$RPN_ADDRESS" and "$RPN_VALUE" which
286          may be read from the new RPN/NRPN script handlers to get the (N)RPN
287          parameter that had been changed and its new value.
288        - Added built-in const variables "$NI_CB_TYPE_RPN" and "$NI_CB_TYPE_NRPN"
289          which are identifying the new (N)RPN handlers as such at script runtime.
290        - Implemented built-in script function "set_rpn()".
291        - Implemented built-in script function "set_nrpn()".
292        - Fix: built-in functions returning an array type were broken and caused a
293          crash when the built-in function's (supposed to be array) result value was
294          used by the script VM.
295        - Removed upper value constraint for 2nd argument of built-in functions
296          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
297          "change_pitch_lfo_freq()","change_reso()", "change_cutoff()",
298          "change_amp_lfo_depth()", "change_cutoff_lfo_depth()" and
299          "change_pitch_lfo_depth()", to allow e.g. passing value 2000000 to double
300          the LFO frequency / resonance / cutoff frequency.
301        - Reduced code involved for parsing NKSP variable declarations by using 2
302          generalized grammar rules with optional components (i.e. optional value
303          assignment and optional variable qualifiers) instead of previous linear
304          combinations of grammar rules, which also fixes some edge case.
305        - NKSP language parser: track code block locations also by a) raw byte
306          position in NKSP source code string and b) length of that code block in
307          bytes (along to the already existing code block tracking by line/column);
308          and added appropriate new members to public C++ API classes like
309          'firstByte' and 'lengthBytes' to class VMSourceToken and struct CodeBlock.
310        - NKSP language: Added support for 'patch' variable qualifier (capture their
311          locations and allow replacement of their assignment expression via VM C++
312          API).
313        - Fixed incorrect EG times if standard measuring unit was passed to built-in
314          functions "change_attack()", "change_decay()" or "change_release()".
315        - Fixed intermediate function result values never having reflected any
316          standard measuring unit type.
317        - Fixed re-entrant issue with function calls which caused wrong result
318          values if the same function was called multiple times in a term
319          (specifically if metric prefixes were used).
320        - NKSP language: Just throw a warning, not an error if an array variable of
321          size zero was declared.
322        - NKSP language: Allow omitting explicit array size on array variable
323          declaration if combined with immediate value assignment
324          (e.g. declare %foo[] := ( 1, 2, 3 ) ).
325        - NKSP language: emit warning if an array variable was declared with bigger
326          array size than amount of initial values been assigned, and initialize the
327          missing array elements with zero in this case.
328        - Fixed built-in NKSP exit() function to behave as return statement.
329        - NKSP parser: Fixed crash if unary '-' operator was used on a non-number
330          data type.
331        - NKSP VM: Fixed the "release" handler being executed too often under
332          certain situations if polyphonic data was passed from "note" handler to
333          "release" handler.
334        - Fixed memory leak in NKSP parser: string tokens were allocated as C
335          strings and never freed.
336        - Fixed incorrect polyphonic data transfer from wrong note handler to
337          release handler; which also fixes no release handler being executed
338          sometimes, and due to the latter it also fixes potential crashes as some
339          polyphonic script events were never released and the engine hence was
340          running out of free script events.
341        - Fixed crash when handling array results of built-in functions
342          (e.g. "num_elements(by_marks($MARK_1)").
343        - NKSP VM: Fixed dead note events not been removed from user's event groups
344          (i.e. causing incorrect behaviour of built-in NKSP functions by_marks()
345          and set_event_mark() after max. size of event group list was exhausted).
346    
347      * test cases:
348        - Fixed compiler errors in test cases.
349        - Updated README for how to compile & run test cases.
350        - Updated test case
351          MutexTest::testDoubleLockStillBlocksConcurrentThread() to latest
352          expected behaviour of the Mutex class implementation (recursive
353          mutex type).
354        - Added test cases for NKSP core language aspects and core built-in
355          functions.
356        - Fixed thread tests segfaulting on Linux.
357        - NKSP: Added real number test cases for built-in functions exit(),
358          int_to_real(), real(), real_to_int() and int(), as well as for the
359          plus, minus and negate language operators.
360        - Added massive amount of NKSP test cases for standard measuring units and
361          'final' operator usage cases.
362        - Added NKSP test cases for (floating point tolerance aware) real number
363          equalness / unequalness comparison.
364        - Added NKSP int array and real array tests for value assignment and
365          initialization of arrays.
366        - Added NKSP test cases for built-in functions "round()", "ceil()",
367          "floor()", "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()",
368          "sin()", "cos()", "tan()", "asin()", "acos()", "atan()".
369        - Added NKSP test cases for unary '+' operator.
370        - Added NKSP test cases for core built-in variables.
371        - Added thorough NKSP test cases for variable declarations.
372    
373      * GigaStudio/Gigasampler format engine:
374        - LFOTriangleIntMath and LFOTriangleIntAbsMath: Fixed FlipPhase=true
375          behaviour for start_level_mid.
376        - Changed LFO start levels: LFO1 and LFO2 both to mid, LFO3 to max. start
377          level (see discussion "GigaStudio LFO compatibility" on mailing list
378          from 2019-09-26 for details).
379        - Changed default wave form for all 3 LFOs to sine (instead of triangle;
380          see discussion "GigaStudio LFO compatibility" on mailing list from
381          2019-09-26 for details).
382        - Format extension: Added support for different LFO wave forms (currently
383          either sine [default], triangle, saw or square).
384        - Format extension: Added support for LFO phase displacement (0°..360°).
385        - Format extension: Added support for flipping LFO polarity on LFO 3
386          (in the original gig format this was only available for LFO 1 and LFO 2).
387        - Format extension: Support for additional filter types:
388          lowpass 1/2/4/6-pole, highpass 1/2/4/6-pole, bandpass 2-pole,
389          bandreject 2-pole.
390        - Fixd potential crash with polynomial interpolator and max. pitch.
391        - If minimum cutoff is defined, remap cutoff controller CC values to really
392          span the entire possible cutoff range (and avoiding a dead controller
393          zone).
394        - Implemented support for loading instrument scripts with 'patch' variables
395          (by patching these script variables with potentially overridden ones by
396          gig Instrument).
397    
398      * SFZ format engine:
399        - Fixed support for regions with loccN/hiccN conditions on more than one
400          MIDI controller.
401        - Fixed internal opcode 'xfin_hivel' falsely being set by user opcode
402          'xfin_lovel' (patch by Christian Czezatke).
403    
404      * Benchmarks:
405        - Fixed benchmarks/triang.cpp falsely having favoured "int math abs"
406          algorithm (since result of 2nd run was not accumulated).
407        - Added benchmark for saw wave (benchmarks/saw.cpp).
408        - Added benchmark for sine wave (benchmarks/sine.cpp).
409        - Added benchmark for square wave (benchmarks/square.cpp).
410        - Increased amount of benchmarks runs by factor 6 to achieve benchmark times
411          which are large enough on modern systems.
412    
413    Version 2.1.1 (27 Jul 2019)
414    
415      * Real-time instrument scripts:
416        - Fixed behavior of built-in NKSP functions change_sustain(),
417          change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain()
418          and change_cutoff_release().
419    
420      * general changes:
421        - Only play release trigger samples on sustain pedal up if this behaviour
422          was explicitly requested by the instrument (otherwise only on note-off).
423        - Fixed compiler warnings.
424        - Fixed compilation error when cross-compiling to Mac.
425        - FX Sends: Provide more useful error messages on routing problems
426          (see bug #169).
427        - LSCP doc: Be more clear describing the two distinct approaches
428          of using external vs. internal effects (see bug #169).
429        - "optional" class: Fixed comparison operators.
430    
431      * Gigasampler/GigaStudio format engine:
432        - Format extension: If requested by instrument then don't play release
433          trigger sample on note-off events.
434    
435      * SFZ format engine:
436        - Fixed memory leak when releasing samples
437          (fixes bug #307, patch by Jacek Roszkowski)
438        - Fixed potential crash when a sample is shared by more than one region
439          (fixes bug #308, patch by Jacek Roszkowski).
440        - Opcode 'sample': Added support for built-in sample '*silence'
441          (fixes bug #310, patch by Jacek Roszkowski).
442    
443    Version 2.1.0 (25 Nov 2017)

449          load real-time instrument script file (NKSP script language).
450        - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
451        - Fixed unintended volume fade-in of voices under certain conditions.
452        - sfz parser: allow missing space between header and opcode
453    
454      * Gigasampler/GigaStudio format engine:
455        - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
456          cutoff settings.
457        - Got rid of resembling an ancient GSt misbehavior which did not pitch at
458          all if an up-pitch of more than 40 semi tones was requested (I don't
459          think there is any stock gig sound that requires this behavior to
460          resemble its original sound).
461        - Added support for controlling whether the individual EGADSR stages may
462          be aborted (as LinuxSampler extension to the original GigaStudio 4
463          format).
464

502        - linuxsampler binary fix: option --create-instruments-db ignored
503          subsequent optional argument due to glibc's implementation oddity
504          which expects a "=" sign, but no space between them.

597        - NKSP Fix: "init" event handler was not always executed when a script
598          was loaded.
599        - NKSP built-in wait() script function: abort script execution if
600          a negative or zero wait time was passed as argument (since this is
601          a common indication of a bug either of the script or even of the
602          engine, which could lead to RT instability or even worse).
603        - ScriptVM: Implemented automatic suspension of RT safety
604          threatening scripts.

621          "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
622          "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".

634          intuitive behavior if used in combination with "change_vol_time()" or
635          "change_tune_time()" respectively: now tuning/volume changes are only
636          assigned (without delay) immediately to a new note if the respective
637          timing function has not been called before, otherwise the volume/tuning
638          changes are automatically faded (before, only the event's time stamp was
639          relevant).
640         - Implemented built-in script function "array_equal()".
641         - Implemented built-in script function "search()".

650         - built-in "play_note()" function now supports a sample playback start
651           offset with argument 3, where special value -1 means to use the regular
652           sample offset as defined by the instrument file.
653         - Built-in array variable %KEY_DOWN[] is now a read-only variable.
654         - Built-in variable $EVENT_NOTE is now a read-only variable.
655         - Built-in variable $EVENT_VELOCITY is now a read-only variable.
656         - built-in "play_note()" function now accepts -2 for its fourth argument
657           (note duration) which means the life time of the note shall be sticked
658           to the requested note number of argument 1.
659         - Fix: built-in "play_note()" function now returns 0 as result value if
660           -1 was passed for its fourth argument (note duration) and the respective
661           parent note is already gone.
662        - Implemented built-in script function "change_play_pos()".

671        - Fixed potential memory access bug and potential undefined behavior of
672          "init" event handlers.
673        - Print a time stamp along to each call of built-in function "message()".
674        - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
675          to retrieve all code blocks filtered out by the preprocessor.
676        - Added built-in script function "fork()".
677        - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
