1  Version CVS HEAD (?)  Version SVN trunk (?)
2    
3    * plugin changes:    * GigaStudio/Gigasampler format engine:
4      - LV2 "state" extension support (patch by David Robillard)      - Use libgig's new IO-per-thread feature to avoid file I/O concurrency
5          issues with .gig file.
6        - Use libgig's new method gig::File::GetSample() with method
7          gig::File::CountSamples() instead of now deprecated
8          gig::File::GetFirstSample() / gig::File::GetNextSample() pair.
9        - Use libgig's new method gig::Instrument::GetRegionAt() with method
10          gig::Instrument:CountRegions() instead of now deprecated
11          gig::Instrument::GetFirstRegion() / gig::Instrument::GetNextRegion() pair.
12    
13    Version 2.2.0 (9 May 2021)
14    
15      * general changes:
16        - Fixed compiler error in Pool.h.
17        - Require C++14 compiler support.
18        - Autoconf: Added m4/ax_cxx_compile_stdcxx.m4 macro which is used
19          for checking in configure for C++14 support (as mandatory
20          requirement) and automatically adds compiler argument if required
21          (e.g. -std=C++14).
22        - RTMath: Implemented floating point comparison methods
23          fEqual32(float,float) and fEqual64(double,double) which take the
24          expected floating point tolerances into account.
25        - Added public API C++ class "LFO", which is a cluster class encapsulating
26          all the sampler's LFO implementations to be used by 3rd party applications
27          (e.g. by Gigedit).
28        - Added int math square LFO implementation.
29        - Added int math saw LFO implementation.
30        - Added numeric complex nr sine LFO implementation.
31        - Marked class LFOTriangleDiHarmonic as deprecated
32          (will be removed in future).
33        - Added LFOAll.h which includes all LFO implementation's header files.
34        - Refactored LFO class names and their file names (PulseLFO -> LFOPulse,
35          LFOSawIntMath -> LFOSawIntMathNew, SawLFO -> LFOSawIntMathOld,
36          SineLFO -> LFOSineBuiltinFn, LFOSine -> LFOSineNumericComplexNr,
37          SquareLFO -> LFOSquarePulse and separated the latter to its own header
38          file).
39        - Renamed type LFOSigned -> LFOTriangleSigned.
40        - Renamed type LFOUnsigned -> LFOTriangleUnsigned.
41        - Using now cubic interpolation as resampling algorithm by default; and
42          linear interpolation is deprecated now.
43        - Event:Init(): memset() entire Event::Param union to zero instead of trying
44          to do that for its individual members; the latter became error prone due
45          to the union's growing complexity meanwhile.
46        - EngineChannel: Overhaul of RPN/NRPN related methods: Added new
47          *Rpn*Parameter*() methods as replacement for previous *Rpn*Controller*()
48          methods and marked the old ones as deprecated; and likewise added new
49          *Nrpn*Parameter*() methods as replacement for previous *Nrpn*Controller*()
50          methods and marked those old ones deprecated as well.
51        - Added support for MIDI CC #38 (data entry LSB): this allows higher value
52          resolution for certain (e.g. hard coded) RPN and NRPN parameters.
53        - Implemented support for compressed RPN/NRPN message sequences (that is to
54          allow processing MIDI data entry messages without always having to be
55          preceded strictly by RPN/NRPN parameter selection messages on each value
56          change).
57        - Added support for MIDI CC #96 (data increment) and MIDI CC #97 (data
58          decrement).
59        - Added support for 'null function RPN/NRPN' (which is RPN/NRPN parameter
60          MSB=127 and LSB=127) and which is disabling subsequent data
61          entry/increment/decrement CC messages.
62        - Fixed crash when editing key groups (a.k.a. exclusive groups) with an
63          instrument editor.
64        - Fixed playing noise at the end of a disk stream under certain conditions.
65        - Fixed potential crash with high pitch at end of RAM playback.
66        - Added configure checks whether C++ compiler supports so called
67          'designated initializers'.
68        - Added global backtraceAsString() function for debugging purposes
69          (POSIX systems only, no Windows implementation yet).
70        - Thread class: Added new methods pushCancelable(), popCancelable(), name(),
71          nameOfCaller() and setNameOfCaller().
72        - configure: Always check for availability of pthread_testcancel() and use
73          it if so (previously it was only used if explicitly enabled by configure
74          option).
75        - Thread class: raise compiler warning if pthread_testcancel() is not
76          available, because it can lead to deadlocks.
77        - Mutex class: Implemented optional bug detection and deadlock debugging
78          features.
79        - Ref<> class is now thread safe (as lock-free and wait-free
80          implementation).
81        - Fixed compilation error with Bison >= 3.6.0.
82        - Fixed rare crash when switching between instruments that had instrument
83          scripts loaded.
84        - Allow EffectChain::InsertEffect() as alternative to
85          EffectChain::AppendEffect() (i.e. with index equal to current chain size).
86        - ConstCapacityArray class: Fixed bug in remove() method.
87        - Fixed crash on certain MIDI RPN and NRPN messages that occurred if no
88          real-time instrument script was loaded.
89    
90      * Real-time instrument scripts:
91        - Added method ScriptVM::setExitResultEnabled() which allows to
92          explicitly enable the built-in exit() function to optionally accept
93          one function argument; the value of the passed exit() function
94          argument will then become available by calling
95          VMExecContext::exitResult() after script execution.
96        - 64 bit support for NKSP integer scripts variables (declare $foo).
97        - Variable names, function names and preprocessor condition names must start
98          with a regular character (a-z or A-Z); starting them with a digit or
99          underscore is not allowed.
100        - NKSP parser fix: equal comparison operator "=" and not equal comparison
101          operator "#" must only accept integer operands.
102        - NKSP language: Implemented support for standard units like Hertz, seconds,
103          Bel including support for metric unit prefixes; so one can now e.g.
104          conveniently use numbers in scripts like "5us" meaning "5 microseconds",
105          or e.g. "12kHz" meaning "12 kilo Hertz", or e.g. "-14mdB" meaning
106          "minus 14 Millidecibel", or e.g. "28c" meaning "28 cents" (for tuning).
107        - NKSP language: Introduced "final" operator "!" which is specifically
108          intended for synthesis parameter values to denote that the synthesis
109          parameter value is intended to be the "final" value for that synthesis
110          parameter that should explicitly be used by the engine and thus causing
111          the sampler engine to ignore all other modulation sources for the same
112          synthesis parameter (like e.g. LFO, EG); by simply prefixing a value,
113          variable or formula with this new "!" operator the expression is marked as
114          being "final".
115        - NKSP script editor API: Added support for detecting standard unit tokens
116          and their potential metric prefix token.
117        - NKSP language: Added support for NKSP real number literals and
118          arithmetic operations on them (e.g. "(3.9 + 2.9) / 12.3 - 42.0").
119        - NKSP language: Added support for NKSP real number (floating point) script
120          variables (declare ~foo).
121        - NKSP language: Added support for NKSP real number (floating point) array
122          script variables (declare ?foo[]).
123        - Built-in script function "message()" accepts now real number argument as
124          well.
125        - Added built-in script function "real_to_int()" and its short hand form
126          "int()" for casting from real number to integer in NKSP scripts.
127        - Added built-in script function "int_to_real()" and its short hand form
128          "real()" for casting from integer to real number in NKSP scripts.
129        - Allow built-in exit() function to potentially accept real number type
130          argument as well.
131        - Built-in script functions may have a different return type depending on
132          the arguments passed to the function.
133        - Built-in script function "abs()" optionally accepts and returns real
134          number.
135        - Built-in script functions "min()" and "max()" optionally accept real
136          number arguments and return real number as result in that case.
137        - NKSP VM API: Allow units and 'final'ness to be returned as result from
138          built-in functions (added methods VMFunction::returnUnitType() and
139          VMFunction::returnsFinal() for that purpose which must be implemented by
140          built-in function implementations).
141        - NKSP language: Allow metric unit prefixes of numeric scalar and array
142          variables to be changed freely at runtime (unlike unit types like Hz etc.
143          which are still sticky, parse-time features of variables which cannot be
144          changed at runtime for the intentional sake of determinism).
145        - NKSP language: 'final' values are prohibited for array variables for now
146          (attempt causes a parsers error).
147        - NKSP language: expressions with unit types (e.g. Hz) are prohibited for
148          conditions of runtime control structures like if(), while(), select()
149          (attempt causes a parser error).
150        - NKSP VM API: Allow built-in functions to perform their own, individual
151          parse time checks of arguments going to be passed to the function at
152          runtime (added method VMFunction::checkArgs() for that purpose).
153        - NKSP language: raise parser warning if only one operand of binary
154          operators (like logical 'or' comparison) contain a 'final' value (because
155          it would always yield in a 'final' result in such cases).
156        - NKSP language: Allow comparison (=, #, <, >, <=, >=) of values with
157          different metric unit prefixes, which will behave as expected (e.g.
158          result of expression '1000us < 2ms' is true).
159        - NKSP language: Allow adding values with different metric unit prefixes
160          (e.g. result of expression '100Hz + 5kHz' is '5100Hz').
161        - NKSP language: Allow subtracting values with different metric unit
162          prefixes (e.g. result of expression '1ms - 20us' is '980us').
163        - NKSP language: Allow multiplying with any metric unit prefixes
164          (e.g. result of expression '2k * 3ms' is '6s'), however multiplications
165          with unit types on both sides (e.g. '2s * 2s') is still prohibited since
166          we don't have any considerable practical use for a term like '4s^2'
167          (hence any attempt multiplying two unit types still causes parser error).
168        - NKSP language: Allow dividing by any metric unit prefixes and allow
169          division of same unit type on both sides (e.g. expression '8kHz / 1000Hz'
170          yields in unit free result '8'). So this is now a way to cast units away
171          e.g. for passing the result to other expressions, certain function calls
172          or variables which are not accepting any units (or that specific unit).
173        - NKSP language: integer arrays and real number arrays can now be converted
174          to strings (e.g. for dumping their content with message() calls for
175          script debugging purposes).
176        - NKSP language: expressions and variables with units are now correctly
177          casted to strings (e.g. with message() calls).
178        - NKSP language: comparing real numbers for equalness (e.g. '~foo = 3.1') or
179          unequalness (e.g. '~foo # 3.1') is now less strict and takes the expected
180          floating point tolerances into account.
181        - NKSP VM API: Added methods VMScalarNumberExpr::evalCastInt() and
182          VMScalarNumberExpr::evalCastReal().
183        - NKSP VM API: Added base class 'VMNumberArrayExpr' for classes
184          'VMIntArrayExpr' and 'VMRealArrayExpr'.
185        - NKSP VM API: replaced all unitPrefix() (parse time) methods by
186          unitFactor() (runtime) methods.
187        - Built-in function "exit()" supports now returning units and 'final'ness
188          for test cases.
189        - The following built-in functions support now units as well: "abs()",
190          "random()", "inc()", "dec()", "in_range()", "min()", "max()",
191          "real_to_int()", "int()", "int_to_real()" and "real()".
192        - Built-in functions "array_equal()", "search()" and "sort()" support now
193          real number arrays (correctly) as well.
194        - Added individual parse time checks of arguments to be passed to built-in
195          functions "random()", "inc()", "dec()", "in_range()", "min()", "max()",
196          "array_equal()" and "search()" specific for their individual purposes.
197        - NKSP VM refactoring: Renamed all methods, functions and classes matching
198          pattern *ScalarNumber* to simply *Number* (that is i.e. classes
199          VMScalarNumberExpr -> VMNumberExpr, ScalarNumberExpr -> NumberExpr,
200          ScalarNumberVariable -> NumberVariable, ScalarNumberBinaryOp ->
201          NumberBinaryOp, VMScalarNumberResultFunction -> VMNumberResultFunction,
202          method VMExpr::asScalarNumberExpr() -> VMExpr::asNumber(), function
203          isScalarNumber() -> isNumber()).
204        - NKSP VM API: Added 4 overridden methods to class VMNumberExpr:
205          evalCastInt(MetricPrefix_t), evalCastInt(MetricPrefix_t,MetricPrefix_t),
206          evalCastReal(MetricPrefix_t), evalCastReal(MetricPrefix_t,MetricPrefix_t)
207          as convenient methods for automatically converting values to expected
208          metric value basis.
209        - Built-in function "wait()" accepts now both integers and real numbers as
210          argument.
211        - NKSP VM API cleanup: Get rid of legacy method
212          VMFunction::argType(vmint iArg) which was already superseded by its new
213          replacement VMFunction::acceptsArgType(vmint iArg, ExprType_t type).
214        - NKSP parser: if wrong argument type was passed to a built-in function and
215          that built-in function accepts more than one data type for the argument,
216          then show all supported data types as parser error message.
217        - Built-in function "play_note()" accepts now real numbers and seconds as
218          unit type as well for its 3rd and 4th function arguments.
219        - The following built-in functions accept now real numbers as well for their
220          2nd function argument: "change_vol()", "change_tune()", "change_cutoff()",
221          "change_attack()", "change_decay()", "change_release()",
222          "change_sustain()", "change_cutoff_attack()", "change_cutoff_decay()",
223          "change_cutoff_sustain()", "change_cutoff_release()",
224          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
225          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
226          "change_pan_time()", "fade_in()", "fade_out()", "change_play_pos()".
227        - Fixed built-in function "change_play_pos()" not having accepted metric
228          prefixes at all.
229        - Fixed the following built-in functions having misinterpreted values given
230          with unit type (for their 2nd argument) as if they were relative values
231          (that is as if they were passed without a unit type): "change_attack()",
232          "change_decay()", "change_release()", "change_cutoff_attack()",
233          "change_cutoff_decay()", "change_cutoff_release()".
234        - Fixed the following built-in functions having applied completely wrong
235          'final' values: "change_sustain()", "change_cutoff_sustain()" (since the
236          respective EGs being their modulation sink assume uint data type with
237          value range 0..1000 instead of 0.0..1.0.
238        - Added individual parse-time checks of function arguments for the following
239          built-in functions: "play_note()", "note_off()", "set_event_mark()",
240          "delete_event_mark()", "by_marks()", "change_cutoff()", "change_attack()",
241          "change_decay()", "change_release()", "change_cutoff_attack()",
242          "change_cutoff_decay()", "change_cutoff_release()",
243          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
244          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()" and
245          "change_pan_time()".
246        - Don't abort function call if unit type was used and at the same time
247          'final' operator was omitted for the primary value argument of the
248          following built-in functions: "change_cutoff()", "change_attack()",
249          "change_decay()", "change_release()", "change_cutoff_attack()",
250          "change_cutoff_decay()", "change_cutoff_release()",
251          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
252          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
253          "change_pan_time()", instead imply 'final'ness at runtime and raise an
254          appropriate parser warning at parse time.
255        - Added built-in real number functions "round()", "ceil()", "floor()",
256          "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()", "sin()",
257          "cos()", "tan()", "asin()", "acos()", "atan()".
258        - Added built-in script real number constant "~NI_MATH_PI".
259        - Added built-in script real number constant "~NI_MATH_E".
260        - NKSP language: Allow unary '+' operator.
261        - Added built-in script functions "msb()" and "lsb()".
262        - NKSP language: Added support for RPN event handler
263          ("on rpn ... end on" in instrument scripts).
264        - NKSP language: Added support for NRPN event handler
265          ("on nrpn ... end on" in instrument scripts).
266        - Added built-in read-only variables "$RPN_ADDRESS" and "$RPN_VALUE" which
267          may be read from the new RPN/NRPN script handlers to get the (N)RPN
268          parameter that had been changed and its new value.
269        - Added built-in const variables "$NI_CB_TYPE_RPN" and "$NI_CB_TYPE_NRPN"
270          which are identifying the new (N)RPN handlers as such at script runtime.
271        - Implemented built-in script function "set_rpn()".
272        - Implemented built-in script function "set_nrpn()".
273        - Fix: built-in functions returning an array type were broken and caused a
274          crash when the built-in function's (supposed to be array) result value was
275          used by the script VM.
276        - Removed upper value constraint for 2nd argument of built-in functions
277          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
278          "change_pitch_lfo_freq()","change_reso()", "change_cutoff()",
279          "change_amp_lfo_depth()", "change_cutoff_lfo_depth()" and
280          "change_pitch_lfo_depth()", to allow e.g. passing value 2000000 to double
281          the LFO frequency / resonance / cutoff frequency.
282        - Reduced code involved for parsing NKSP variable declarations by using 2
283          generalized grammar rules with optional components (i.e. optional value
284          assignment and optional variable qualifiers) instead of previous linear
285          combinations of grammar rules, which also fixes some edge case.
286        - NKSP language parser: track code block locations also by a) raw byte
287          position in NKSP source code string and b) length of that code block in
288          bytes (along to the already existing code block tracking by line/column);
289          and added appropriate new members to public C++ API classes like
290          'firstByte' and 'lengthBytes' to class VMSourceToken and struct CodeBlock.
291        - NKSP language: Added support for 'patch' variable qualifier (capture their
292          locations and allow replacement of their assignment expression via VM C++
293          API).
294        - Fixed incorrect EG times if standard measuring unit was passed to built-in
295          functions "change_attack()", "change_decay()" or "change_release()".
296        - Fixed intermediate function result values never having reflected any
297          standard measuring unit type.
298        - Fixed re-entrant issue with function calls which caused wrong result
299          values if the same function was called multiple times in a term
300          (specifically if metric prefixes were used).
301        - NKSP language: Just throw a warning, not an error if an array variable of
302          size zero was declared.
303        - NKSP language: Allow omitting explicit array size on array variable
304          declaration if combined with immediate value assignment
305          (e.g. declare %foo[] := ( 1, 2, 3 ) ).
306        - NKSP language: emit warning if an array variable was declared with bigger
307          array size than amount of initial values been assigned, and initialize the
308          missing array elements with zero in this case.
309        - Fixed built-in NKSP exit() function to behave as return statement.
310        - NKSP parser: Fixed crash if unary '-' operator was used on a non-number
311          data type.
312        - NKSP VM: Fixed the "release" handler being executed too often under
313          certain situations if polyphonic data was passed from "note" handler to
314          "release" handler.
315        - Fixed memory leak in NKSP parser: string tokens were allocated as C
316          strings and never freed.
317        - Fixed incorrect polyphonic data transfer from wrong note handler to
318          release handler; which also fixes no release handler being executed
319          sometimes, and due to the latter it also fixes potential crashes as some
320          polyphonic script events were never released and the engine hence was
321          running out of free script events.
322        - Fixed crash when handling array results of built-in functions
323          (e.g. "num_elements(by_marks($MARK_1)").
324        - NKSP VM: Fixed dead note events not been removed from user's event groups
325          (i.e. causing incorrect behaviour of built-in NKSP functions by_marks()
326          and set_event_mark() after max. size of event group list was exhausted).
327    
328      * test cases:
329        - Fixed compiler errors in test cases.
330        - Updated README for how to compile & run test cases.
331        - Updated test case
332          MutexTest::testDoubleLockStillBlocksConcurrentThread() to latest
333          expected behaviour of the Mutex class implementation (recursive
334          mutex type).
335        - Added test cases for NKSP core language aspects and core built-in
336          functions.
337        - Fixed thread tests segfaulting on Linux.
338        - NKSP: Added real number test cases for built-in functions exit(),
339          int_to_real(), real(), real_to_int() and int(), as well as for the
340          plus, minus and negate language operators.
341        - Added massive amount of NKSP test cases for standard measuring units and
342          'final' operator usage cases.
343        - Added NKSP test cases for (floating point tolerance aware) real number
344          equalness / unequalness comparison.
345        - Added NKSP int array and real array tests for value assignment and
346          initialization of arrays.
347        - Added NKSP test cases for built-in functions "round()", "ceil()",
348          "floor()", "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()",
349          "sin()", "cos()", "tan()", "asin()", "acos()", "atan()".
350        - Added NKSP test cases for unary '+' operator.
351        - Added NKSP test cases for core built-in variables.
352        - Added thorough NKSP test cases for variable declarations.
353    
354      * GigaStudio/Gigasampler format engine:
355        - LFOTriangleIntMath and LFOTriangleIntAbsMath: Fixed FlipPhase=true
356          behaviour for start_level_mid.
357        - Changed LFO start levels: LFO1 and LFO2 both to mid, LFO3 to max. start
358          level (see discussion "GigaStudio LFO compatibility" on mailing list
359          from 2019-09-26 for details).
360        - Changed default wave form for all 3 LFOs to sine (instead of triangle;
361          see discussion "GigaStudio LFO compatibility" on mailing list from
362          2019-09-26 for details).
363        - Format extension: Added support for different LFO wave forms (currently
364          either sine [default], triangle, saw or square).
365        - Format extension: Added support for LFO phase displacement (0°..360°).
366        - Format extension: Added support for flipping LFO polarity on LFO 3
367          (in the original gig format this was only available for LFO 1 and LFO 2).
368        - Format extension: Support for additional filter types:
369          lowpass 1/2/4/6-pole, highpass 1/2/4/6-pole, bandpass 2-pole,
370          bandreject 2-pole.
371        - Fixd potential crash with polynomial interpolator and max. pitch.
372        - If minimum cutoff is defined, remap cutoff controller CC values to really
373          span the entire possible cutoff range (and avoiding a dead controller
374          zone).
375        - Implemented support for loading instrument scripts with 'patch' variables
376          (by patching these script variables with potentially overridden ones by
377          gig Instrument).
378    
379      * SFZ format engine:
380        - Fixed support for regions with loccN/hiccN conditions on more than one
381          MIDI controller.
382        - Fixed internal opcode 'xfin_hivel' falsely being set by user opcode
383          'xfin_lovel' (patch by Christian Czezatke).
384    
385      * Benchmarks:
386        - Fixed benchmarks/triang.cpp falsely having favoured "int math abs"
387          algorithm (since result of 2nd run was not accumulated).
388        - Added benchmark for saw wave (benchmarks/saw.cpp).
389        - Added benchmark for sine wave (benchmarks/sine.cpp).
390        - Added benchmark for square wave (benchmarks/square.cpp).
391        - Increased amount of benchmarks runs by factor 6 to achieve benchmark times
392          which are large enough on modern systems.
393    
394    Version 2.1.1 (27 Jul 2019)
395    
396      * Real-time instrument scripts:
397        - Fixed behavior of built-in NKSP functions change_sustain(),
398          change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain()
399          and change_cutoff_release().
400    
401      * general changes:
402        - Only play release trigger samples on sustain pedal up if this behaviour
403          was explicitly requested by the instrument (otherwise only on note-off).
404        - Fixed compiler warnings.
405        - Fixed compilation error when cross-compiling to Mac.
406        - FX Sends: Provide more useful error messages on routing problems
407          (see bug #169).
408        - LSCP doc: Be more clear describing the two distinct approaches
409          of using external vs. internal effects (see bug #169).
410        - "optional" class: Fixed comparison operators.
411    
412      * Gigasampler/GigaStudio format engine:
413        - Format extension: If requested by instrument then don't play release
414          trigger sample on note-off events.
415    
416      * SFZ format engine:
417        - Fixed memory leak when releasing samples
418          (fixes bug #307, patch by Jacek Roszkowski)
419        - Fixed potential crash when a sample is shared by more than one region
420          (fixes bug #308, patch by Jacek Roszkowski).
421        - Opcode 'sample': Added support for built-in sample '*silence'
422          (fixes bug #310, patch by Jacek Roszkowski).
423    
424    Version 2.1.0 (25 Nov 2017)
425    
426      * SFZ format engine:
427        - added support for <global>, <master> and #define (patch by Alby M)
428        - Removed code duplication in SFZ file loading code.
429        - Added support for sfz extension opcode 'script' which may be used to
430          load real-time instrument script file (NKSP script language).
431        - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
432        - Fixed unintended volume fade-in of voices under certain conditions.
433        - sfz parser: allow missing space between header and opcode
434    
435      * Gigasampler/GigaStudio format engine:
436        - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
437          cutoff settings.
438        - Got rid of resembling an ancient GSt misbehavior which did not pitch at
439          all if an up-pitch of more than 40 semi tones was requested (I don't
440          think there is any stock gig sound that requires this behavior to
441          resemble its original sound).
442        - Added support for controlling whether the individual EGADSR stages may
443          be aborted (as LinuxSampler extension to the original GigaStudio 4
444          format).
445    
446      * general changes:
447        - fixed printf type errors (mostly in debug messages)
448        - use unique_ptr instead of auto_ptr when building with C++11
449        - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
450          allowing to sort data efficiently in real-time safe manner.
451        - RTList class: added methods for moving/inserting elements to arbitrary
452          position within a list.
453        - RTList class: added method fromPtr() for creating an Iterator object from
454          a raw element pointer.
455        - Attempt to partly fix resetting engine channels vs. resetting engine, an
456          overall cleanup of the Reset*(), ConnectAudioDevice(),
457          DisconnectAudioDevice() API methods would still be desirable though,
458          because the current situation is still inconsistent and error prone.
459        - Active voices are now internally grouped to "Note" objects, instead of
460          being directly assigned to a keyboard key. This allows more fine graded
461          processing of voices, which is i.e. required for certain instrument
462          script features.
463        - Fix: Release trigger voices were not spawned on sustain pedal up
464          (CC #64) events.
465        - Fix: Release trigger voices can now also distinguish correctly between
466          note-off and sustain pedal up events.
467        - All engines: Increased ramp speed of volume smoother and pan smoother
468          (while slow rate of crossfade smoother is preserved) to allow quick
469          volume and pan changes by instrument scripts for instance.
470        - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
471          properly and thus were ignored for certain uses.
472        - Added new C++ API method
473          VirtualMidiDevice::SendChannelPressureToSampler().
474        - windows, 32-bit: fixed potential crashes by making sure the stack in
475          sub threads is 16-byte aligned
476        - fixed numerous compiler warnings
477        - Fixed invalid (note-on) event ID being assigned to new Note objects.
478        - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
479          fixes potential undefined behavior.
480        - Fixed Note object leak when triggering notes on keys which did not
481          have a valid sample mapped (fixes bug #252).
482        - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
483        - linuxsampler binary fix: option --create-instruments-db ignored
484          subsequent optional argument due to glibc's implementation oddity
485          which expects a "=" sign, but no space between them.
486    
487      * packaging changes:
488        - removed unnecessary dependency to libuuid
489          (originated by libgig's usage of it)
490        - Automake: set environment variable GCC_COLORS=auto to allow GCC to
491          auto detect whether it (sh/c)ould output its messages in color.
492        - Debian: Fixed packaging error about invalid "Source-Version"
493          substitution variable.
494        - Debian: Raised Debian compatibility level to Debian 9 "Stretch".
495        - Debian: Added build dependency to libsqlite3-dev for building
496          linuxsampler with instruments DB support.
497    
498      * Real-time instrument scripts:
499        - Implemented scheduler for delayed MIDI events and for suspended scripts.
500        - Built-in script function "wait()": implemented support for function's
501          "duration-us" argument, thus scripts using this function are now
502          correctly resumed after the requested amount of microseconds.
503        - Built-in script function "play_note()": implemented support for
504          function's "duration-us" argument, thus notes triggered with this
505          argument are now correctly released after the requested amount of
506          microseconds.
507        - Fix: script events were not cleared when engine channel was reset,
508          potentially causing undefined behavior.
509        - Fixed crash which happened when trying to reference an undeclared
510          variable.
511        - Built-in script function "play_note()": Added support for passing
512          special value -1 for "duration-us" argument, which will cause the
513          triggered note to be released once the original note was released.
514        - Instrument script classes now exported with the liblinuxsampler C++ API.
515        - Added new API method ScriptVM::syntaxHighlighting() which provides
516          a convenient syntax highlighting backend for external instrument
517          script editor applications.
518        - Added new C++ API class "ScriptVMFactory".
519        - Extended parser issues to provide not only first line and first
520          column, but also last line and last column of issue (thus marking
521          the precise span of the issue within the source code).
522        - Reload script automatically after being modified by an instrument
523          editor.
524        - NKSP language grammar correction: allow empty event handler bodies
525          like "on note end on".
526        - Implemented built-in script function "change_vol()".
527        - Implemented built-in script function "change_tune()".
528        - Implemented built-in script function "change_pan()".

530        - Implemented built-in script function "change_reso()".
531        - Implemented built-in script function "event_status()".
532        - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
533          "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
534          "event_status()" function.
535        - NKSP language: Added support for bitwise operators ".or.", ".and."
536          and ".not.".
537        - NKSP language scanner: Fixed IDs matching to require at least one
538          character (i.e. when matching function names or variable names).
539        - NKSP language scanner: disabled unusued rules.
540        - Fixed behavior of play_note() and note_off() functions which must
541          be distinguished engine internally from "real" MIDI note on/off
542          events in order to avoid misbehaviors like hanging notes.
543        - Implemented built-in script variable "$KSP_TIMER".
544        - Implemented built-in script variable "$NKSP_REAL_TIMER".
545        - Implemented built-in script variable "$NKSP_PERF_TIMER".
546        - Implemented built-in script variable "$ENGINE_UPTIME".
547        - Implemented built-in script function "inc()".
548        - Implemented built-in script function "dec()".
549        - NKSP language fix: division expressions were evaluated too often.
550        - NKSP language fix: string concatenation operator was right
551          associative instead of left (to right).
552        - NKSP language correction: allow empty statements in entire language
553          (i.e. "if end if").
554        - Implemented built-in script function "stop_wait()".
555        - Implemented built-in script variable "$NI_CALLBACK_ID".
556        - Implemented built-in script variable "$NI_CALLBACK_TYPE".
557        - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
558        - Added support for read-only built-in variables (respectively
559          handled by the script parser).
560        - Added built-in script constant "$NI_CB_TYPE_INIT".
561        - Added built-in script constant "$NI_CB_TYPE_NOTE".
562        - Added built-in script constant "$NI_CB_TYPE_RELEASE".

566        - Implemented built-in script function "change_decay()".
567        - Implemented built-in script function "change_release()".
568        - Fixed all change_*() built-in script functions to apply their
569          synthesis parameter changes immediately in case the respective note
570          was triggered at the same time, instead of scheduling the parameter
571          change, especially because it would cause some parameter types's
572          changes either to be ramped (i.e. change_vol()) or other types even
573          to have not effect at all (i.e. change_attack()).
574        - Implemented built-in script function "sh_left()".
575        - Implemented built-in script function "sh_right()".
576        - Implemented built-in script function "min()".
577        - Implemented built-in script function "max()".
578        - NKSP Fix: "init" event handler was not always executed when a script
579          was loaded.
580        - NKSP built-in wait() script function: abort script execution if
581          a negative or zero wait time was passed as argument (since this is
582          a common indication of a bug either of the script or even of the
583          engine, which could lead to RT instability or even worse).
584        - ScriptVM: Implemented automatic suspension of RT safety
585          threatening scripts.
586        - Provide more user friendly error messages on syntax errors.
587        - Fixed NKSP parser warning "Not a statement" when assigning an
588          initializer list to an array variable.
589        - Implemented built-in script array variable "%ALL_EVENTS".
590        - Implemented built-in script function "in_range()".
591        - Implemented built-in script function "change_amp_lfo_depth()".
592        - Implemented built-in script function "change_amp_lfo_freq()".

596        - Implemented built-in script function "change_tune_time()".
597        - Implemented built-in script function "fade_in()".
598        - Implemented built-in script function "fade_out()".
599        - Fixed acceptance of wrong data type of parameters passed to built-in
600          script functions "change_vol()", "change_tune()", "change_pan()",
601          "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
602          "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
603          "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
604        - Added built-in script function "get_event_par()" and implemented some
605          of its possible parameter selections.
606        - Added built-in script function "set_event_par()" and implemented some
607          of its possible parameter selections.
608        - Fixed a bunch of scheduler time related bugs.
609        - Fixed polyphonic variables not being reset to zero after usage.
610        - Built-in "ignore_event()" function: argument is now optional, like with
611          built-in function "ignore_controller()".
612        - Implemented built-in script function "change_velo()".
613        - Implemented built-in script function "change_note()".
614        - Adjusted behavior of "change_vol()" and "change_tune()" to a more
615          intuitive behavior if used in combination with "change_vol_time()" or
616          "change_tune_time()" respectively: now tuning/volume changes are only
617          assigned (without delay) immediately to a new note if the respective
618          timing function has not been called before, otherwise the volume/tuning
619          changes are automatically faded (before, only the event's time stamp was
620          relevant).
621         - Implemented built-in script function "array_equal()".
622         - Implemented built-in script function "search()".
623         - Implemented built-in script function "sort()".
624         - NKSP Fix: Never suspend "init" event handlers.
625         - Implemented built-in script function "same_region()" (currently only
626           available for gig format engine).
627         - Added built-in script constant "$NKSP_LINEAR".
628         - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
629         - Implemented built-in script function "change_vol_curve()".
630         - Implemented built-in script function "change_tune_curve()".
631         - built-in "play_note()" function now supports a sample playback start
632           offset with argument 3, where special value -1 means to use the regular
633           sample offset as defined by the instrument file.
634         - Built-in array variable %KEY_DOWN[] is now a read-only variable.
635         - Built-in variable $EVENT_NOTE is now a read-only variable.
636         - Built-in variable $EVENT_VELOCITY is now a read-only variable.
637         - built-in "play_note()" function now accepts -2 for its fourth argument
638           (note duration) which means the life time of the note shall be sticked
639           to the requested note number of argument 1.
640         - Fix: built-in "play_note()" function now returns 0 as result value if
641           -1 was passed for its fourth argument (note duration) and the respective
642           parent note is already gone.
643        - Implemented built-in script function "change_play_pos()".
644        - NKSP language: Added support for user declared const array variables.
645        - NKSP language: Raise parser warning if array variable is accessed with
646          an index that exceeds the array's size.
647        - NKSP language fix: Unknown characters were not handled correctly.
648        - NKSP language: Added support for "synchronized .. end synchronized"
649          code blocks.
650        - Implemented built-in script function "abort()" which allows to abort
651          another script handler by passing its callback ID.
652        - Fixed potential memory access bug and potential undefined behavior of
653          "init" event handlers.
654        - Print a time stamp along to each call of built-in function "message()".
655        - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
656          to retrieve all code blocks filtered out by the preprocessor.
657        - Added built-in script function "fork()".
658        - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
659        - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
660        - Fixed potential crash when accessing dynamic built-in array variables.

665        - Removed max. value limitation of built-in functions "change_attack()",
666          "change_decay()" and "change_release()" to i.e. allow passing 2000000
667          for doubling the respective time.
668        - NKSP script editor syntax highlighting API: Fixed app termination due
669          to a lexer start condition stack underrun.
670        - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
671          USE_CODE_IF_NOT() preprocessor statements.
672        - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
673          can be set to disable all subsequent built-in "message()" function calls
674          on preprocessor level.
675        - Implemented built-in script function "change_sustain()".
676        - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
677          to avoid the editor app to crash on ill-formed text input.
678        - Added built-in script function "change_pan_time()".
679        - Added built-in script function "change_pan_curve()".

688        - Fixed memory access bug of general DB access code which lead to
689          undefined behavior.
690        - Cleanup of instruments DB file creation and opening code.
691        - The instrument DB path of linuxsampler's --create-instruments-db argument
692          is now optional, if it is missing, then a default location is used.
693        - Added support for scanning SFZ (.sfz) files.
694        - Added support for scanning Sound Font (.sf2) files.
695        - Fixed undefined DB transaction behavior.
696

761      - added command line option --exec-after-init      - added command line option --exec-after-init
762        - Introduced new C++ API method:
763          EngineChannel::InstrumentFileName(int index)
764          allowing to retrieve the whole list of files used for the loaded
765          instrument on an engine channel (a.k.a. part). Some GigaStudio
766          instruments for example are splitted over several files like
767          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
768        - Added new C++ API method Sampler::GetGlobalMaxVoices().
769        - Added new C++ API method Sampler::GetGlobalMaxStreams().
770        - Added new C++ API method Sampler::SetGlobalMaxVoices().
771        - Added new C++ API method Sampler::SetGlobalMaxStreams().
772        - Various "const" and "restrict" optimizations.
773        - all engines: add pan CC value to instrument pan parameter before
774          applying panning, instead of using two separate pan functions in
775          series (#182)
776        - added a lock guard class for exception safe mutex handling and
777          used it everywhere appropriate
778        - Immediately apply scale tuning changes to active voices.
779        - Exposed scale tuning to C++ API (along to the already existing standard
780          SysEx way).
781        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
782          and broken for ppc64. (Seq_cst loads and stores are actually not
783          used in LS, so the bug wasn't noticable.)
784        - lsatomic.h: added ARMv7 support
785        - Added support for multiple MIDI input ports per sampler channel (and
786          added various new C++ methods for this new feature / design change, old
787          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
788          as deprecated but are still there and should provide full behavior
789          backward compatibility).
790        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
791          unsafe and caused compilation error with clang 2.x).
792        - Bugfix: only process the latest MIDI program change event.
793        - Introducing the LSCP shell, which provides convenient control of the
794          sampler from the command line by providing LSCP aware features.
795        - VirtualMidiDevice: Added support for program change.
796        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
797        - VirtualMidiDevice: Added support for pitch bend.
798        - Aftertouch: extended API to explicitly handle channel pressure and
799          polyphonic key pressure events (so far polyphonic pressure was not
800          supported at all, and channel pressure was rerouted as CC128 but not
801          used so far).
802        - Added initial support for real-time instrument scripts. The script VM
803          code is shared by all sampler engine implemementations, however only the
804          gig file format currently provides support for storing instrument scripts
805          (as LinuxSampler extension to the original GigaStudio 4 format).

1182        - Pass/preserve polyphonic variable data from respective "note" event
1183          handler to "release" event handler.
