2    
3    * plugin changes:    * general changes:
4      - LV2 Persist + Files support (patch by David Robillard)      - Fixed compiler error in Pool.h.
5        - Require C++14 compiler support.
6        - Autoconf: Added m4/ax_cxx_compile_stdcxx.m4 macro which is used
7          for checking in configure for C++14 support (as mandatory
8          requirement) and automatically adds compiler argument if required
9          (e.g. -std=C++14).
10        - RTMath: Implemented floating point comparison methods
11          fEqual32(float,float) and fEqual64(double,double) which take the
12          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    
42      * Real-time instrument scripts:
43        - Added method ScriptVM::setExitResultEnabled() which allows to
44          explicitly enable the built-in exit() function to optionally accept
45          one function argument; the value of the passed exit() function
46          argument will then become available by calling
47          VMExecContext::exitResult() after script execution.
48        - 64 bit support for NKSP integer scripts variables (declare $foo).
49        - Variable names, function names and preprocessor condition names must start
50          with a regular character (a-z or A-Z); starting them with a digit or
51          underscore is not allowed.
52        - NKSP parser fix: equal comparison operator "=" and not equal comparison
53          operator "#" must only accept integer operands.
54        - NKSP language: Implemented support for standard units like Hertz, seconds,
55          Bel including support for metric unit prefixes; so one can now e.g.
56          conveniently use numbers in scripts like "5us" meaning "5 microseconds",
57          or e.g. "12kHz" meaning "12 kilo Hertz", or e.g. "-14mdB" meaning
58          "minus 14 Millidecibel", or e.g. "28c" meaning "28 cents" (for tuning).
59        - NKSP language: Introduced "final" operator "!" which is specifically
60          intended for synthesis parameter values to denote that the synthesis
61          parameter value is intended to be the "final" value for that synthesis
62          parameter that should explicitly be used by the engine and thus causing
63          the sampler engine to ignore all other modulation sources for the same
64          synthesis parameter (like e.g. LFO, EG); by simply prefixing a value,
65          variable or formula with this new "!" operator the expression is marked as
66          being "final".
67        - NKSP script editor API: Added support for detecting standard unit tokens
68          and their potential metric prefix token.
69        - NKSP language: Added support for NKSP real number literals and
70          arithmetic operations on them (e.g. "(3.9 + 2.9) / 12.3 - 42.0").
71        - NKSP language: Added support for NKSP real number (floating point) script
72          variables (declare ~foo).
73        - NKSP language: Added support for NKSP real number (floating point) array
74          script variables (declare ?foo[]).
75        - Built-in script function "message()" accepts now real number argument as
76          well.
77        - Added built-in script function "real_to_int()" and its short hand form
78          "int()" for casting from real number to integer in NKSP scripts.
79        - Added built-in script function "int_to_real()" and its short hand form
80          "real()" for casting from integer to real number in NKSP scripts.
81        - Allow built-in exit() function to potentially accept real number type
82          argument as well.
83        - Built-in script functions may have a different return type depending on
84          the arguments passed to the function.
85        - Built-in script function "abs()" optionally accepts and returns real
86          number.
87        - Built-in script functions "min()" and "max()" optionally accept real
88          number arguments and return real number as result in that case.
89        - NKSP VM API: Allow units and 'final'ness to be returned as result from
90          built-in functions (added methods VMFunction::returnUnitType() and
91          VMFunction::returnsFinal() for that purpose which must be implemented by
92          built-in function implementations).
93        - NKSP language: Allow metric unit prefixes of numeric scalar and array
94          variables to be changed freely at runtime (unlike unit types like Hz etc.
95          which are still sticky, parse-time features of variables which cannot be
96          changed at runtime for the intentional sake of determinism).
97        - NKSP language: 'final' values are prohibited for array variables for now
98          (attempt causes a parsers error).
99        - NKSP language: expressions with unit types (e.g. Hz) are prohibited for
100          conditions of runtime control structures like if(), while(), select()
101          (attempt causes a parser error).
102        - NKSP VM API: Allow built-in functions to perform their own, individual
103          parse time checks of arguments going to be passed to the function at
104          runtime (added method VMFunction::checkArgs() for that purpose).
105        - NKSP language: raise parser warning if only one operand of binary
106          operators (like logical 'or' comparison) contain a 'final' value (because
107          it would always yield in a 'final' result in such cases).
108        - NKSP language: Allow comparison (=, #, <, >, <=, >=) of values with
109          different metric unit prefixes, which will behave as expected (e.g.
110          result of expression '1000us < 2ms' is true).
111        - NKSP language: Allow adding values with different metric unit prefixes
112          (e.g. result of expression '100Hz + 5kHz' is '5100Hz').
113        - NKSP language: Allow subtracting values with different metric unit
114          prefixes (e.g. result of expression '1ms - 20us' is '980us').
115        - NKSP language: Allow multiplying with any metric unit prefixes
116          (e.g. result of expression '2k * 3ms' is '6s'), however multiplications
117          with unit types on both sides (e.g. '2s * 2s') is still prohibited since
118          we don't have any considerable practical use for a term like '4s^2'
119          (hence any attempt multiplying two unit types still causes parser error).
120        - NKSP language: Allow dividing by any metric unit prefixes and allow
121          division of same unit type on both sides (e.g. expression '8kHz / 1000Hz'
122          yields in unit free result '8'). So this is now a way to cast units away
123          e.g. for passing the result to other expressions, certain function calls
124          or variables which are not accepting any units (or that specific unit).
125        - NKSP language: integer arrays and real number arrays can now be converted
126          to strings (e.g. for dumping their content with message() calls for
127          script debugging purposes).
128        - NKSP language: expressions and variables with units are now correctly
129          casted to strings (e.g. with message() calls).
130        - NKSP language: comparing real numbers for equalness (e.g. '~foo = 3.1') or
131          unequalness (e.g. '~foo # 3.1') is now less strict and takes the expected
132          floating point tolerances into account.
133        - NKSP VM API: Added methods VMScalarNumberExpr::evalCastInt() and
134          VMScalarNumberExpr::evalCastReal().
135        - NKSP VM API: Added base class 'VMNumberArrayExpr' for classes
136          'VMIntArrayExpr' and 'VMRealArrayExpr'.
137        - NKSP VM API: replaced all unitPrefix() (parse time) methods by
138          unitFactor() (runtime) methods.
139        - Built-in function "exit()" supports now returning units and 'final'ness
140          for test cases.
141        - The following built-in functions support now units as well: "abs()",
142          "random()", "inc()", "dec()", "in_range()", "min()", "max()",
143          "real_to_int()", "int()", "int_to_real()" and "real()".
144        - Built-in functions "array_equal()", "search()" and "sort()" support now
145          real number arrays (correctly) as well.
146        - Added individual parse time checks of arguments to be passed to built-in
147          functions "random()", "inc()", "dec()", "in_range()", "min()", "max()",
148          "array_equal()" and "search()" specific for their individual purposes.
149        - NKSP VM refactoring: Renamed all methods, functions and classes matching
150          pattern *ScalarNumber* to simply *Number* (that is i.e. classes
151          VMScalarNumberExpr -> VMNumberExpr, ScalarNumberExpr -> NumberExpr,
152          ScalarNumberVariable -> NumberVariable, ScalarNumberBinaryOp ->
153          NumberBinaryOp, VMScalarNumberResultFunction -> VMNumberResultFunction,
154          method VMExpr::asScalarNumberExpr() -> VMExpr::asNumber(), function
155          isScalarNumber() -> isNumber()).
156        - NKSP VM API: Added 4 overridden methods to class VMNumberExpr:
157          evalCastInt(MetricPrefix_t), evalCastInt(MetricPrefix_t,MetricPrefix_t),
158          evalCastReal(MetricPrefix_t), evalCastReal(MetricPrefix_t,MetricPrefix_t)
159          as convenient methods for automatically converting values to expected
160          metric value basis.
161        - Built-in function "wait()" accepts now both integers and real numbers as
162          argument.
163        - NKSP VM API cleanup: Get rid of legacy method
164          VMFunction::argType(vmint iArg) which was already superseded by its new
165          replacement VMFunction::acceptsArgType(vmint iArg, ExprType_t type).
166        - NKSP parser: if wrong argument type was passed to a built-in function and
167          that built-in function accepts more than one data type for the argument,
168          then show all supported data types as parser error message.
169        - Built-in function "play_note()" accepts now real numbers and seconds as
170          unit type as well for its 3rd and 4th function arguments.
171        - The following built-in functions accept now real numbers as well for their
172          2nd function argument: "change_vol()", "change_tune()", "change_cutoff()",
173          "change_attack()", "change_decay()", "change_release()",
174          "change_sustain()", "change_cutoff_attack()", "change_cutoff_decay()",
175          "change_cutoff_sustain()", "change_cutoff_release()",
176          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
177          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
178          "change_pan_time()", "fade_in()", "fade_out()", "change_play_pos()".
179        - Fixed built-in function "change_play_pos()" not having accepted metric
180          prefixes at all.
181        - Fixed the following built-in functions having misinterpreted values given
182          with unit type (for their 2nd argument) as if they were relative values
183          (that is as if they were passed without a unit type): "change_attack()",
184          "change_decay()", "change_release()", "change_cutoff_attack()",
185          "change_cutoff_decay()", "change_cutoff_release()".
186        - Fixed the following built-in functions having applied completely wrong
187          'final' values: "change_sustain()", "change_cutoff_sustain()" (since the
188          respective EGs being their modulation sink assume uint data type with
189          value range 0..1000 instead of 0.0..1.0.
190        - Added individual parse-time checks of function arguments for the following
191          built-in functions: "play_note()", "note_off()", "set_event_mark()",
192          "delete_event_mark()", "by_marks()", "change_cutoff()", "change_attack()",
193          "change_decay()", "change_release()", "change_cutoff_attack()",
194          "change_cutoff_decay()", "change_cutoff_release()",
195          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
196          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()" and
197          "change_pan_time()".
198        - Don't abort function call if unit type was used and at the same time
199          'final' operator was omitted for the primary value argument of the
200          following built-in functions: "change_cutoff()", "change_attack()",
201          "change_decay()", "change_release()", "change_cutoff_attack()",
202          "change_cutoff_decay()", "change_cutoff_release()",
203          "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
204          "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
205          "change_pan_time()", instead imply 'final'ness at runtime and raise an
206          appropriate parser warning at parse time.
207        - Added built-in real number functions "round()", "ceil()", "floor()",
208          "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()", "sin()",
209          "cos()", "tan()", "asin()", "acos()", "atan()".
210        - Added built-in script real number constant "~NI_MATH_PI".
211        - Added built-in script real number constant "~NI_MATH_E".
212        - NKSP language: Allow unary '+' operator.
213        - Added built-in script functions "msb()" and "lsb()".
214    
215      * test cases:
216        - Fixed compiler errors in test cases.
217        - Updated README for how to compile & run test cases.
218        - Updated test case
219          MutexTest::testDoubleLockStillBlocksConcurrentThread() to latest
220          expected behaviour of the Mutex class implementation (recursive
221          mutex type).
222        - Added test cases for NKSP core language aspects and core built-in
223          functions.
224        - Fixed thread tests segfaulting on Linux.
225        - NKSP: Added real number test cases for built-in functions exit(),
226          int_to_real(), real(), real_to_int() and int(), as well as for the
227          plus, minus and negate language operators.
228        - Added massive amount of NKSP test cases for standard measuring units and
229          'final' operator usage cases.
230        - Added NKSP test cases for (floating point tolerance aware) real number
231          equalness / unequalness comparison.
232        - Added NKSP int array and real array tests for value assignment and
233          initialization of arrays.
234        - Added NKSP test cases for built-in functions "round()", "ceil()",
235          "floor()", "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()",
236          "sin()", "cos()", "tan()", "asin()", "acos()", "atan()".
237        - Added NKSP test cases for unary '+' operator.
238    
239      * GigaStudio/Gigasampler format engine:
240        - LFOTriangleIntMath and LFOTriangleIntAbsMath: Fixed FlipPhase=true
241          behaviour for start_level_mid.
242        - Changed LFO start levels: LFO1 and LFO2 both to mid, LFO3 to max. start
243          level (see discussion "GigaStudio LFO compatibility" on mailing list
244          from 2019-09-26 for details).
245        - Changed default wave form for all 3 LFOs to sine (instead of triangle;
246          see discussion "GigaStudio LFO compatibility" on mailing list from
247          2019-09-26 for details).
248        - Format extension: Added support for different LFO wave forms (currently
249          either sine [default], triangle, saw or square).
250        - Format extension: Added support for LFO phase displacement (0°..360°).
251        - Format extension: Added support for flipping LFO polarity on LFO 3
252          (in the original gig format this was only available for LFO 1 and LFO 2).
253        - Format extension: Support for additional filter types:
254          lowpass 1/2/4/6-pole, highpass 1/2/4/6-pole, bandpass 2-pole,
255          bandreject 2-pole.
256    
257      * SFZ format engine:
258        - Fixed support for regions with loccN/hiccN conditions on more than one
259          MIDI controller.
260    
261      * Benchmarks:
262        - Fixed benchmarks/triang.cpp falsely having favoured "int math abs"
263          algorithm (since result of 2nd run was not accumulated).
264        - Added benchmark for saw wave (benchmarks/saw.cpp).
265        - Added benchmark for sine wave (benchmarks/sine.cpp).
266        - Added benchmark for square wave (benchmarks/square.cpp).
267        - Increased amount of benchmarks runs by factor 6 to achieve benchmark times
268          which are large enough on modern systems.
269    
270    Version 2.1.1 (27 Jul 2019)
271    
272      * Real-time instrument scripts:
273        - Fixed behavior of built-in NKSP functions change_sustain(),
274          change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain()
275          and change_cutoff_release().
276    
277      * general changes:
278        - Only play release trigger samples on sustain pedal up if this behaviour
279          was explicitly requested by the instrument (otherwise only on note-off).
280        - Fixed compiler warnings.
281        - Fixed compilation error when cross-compiling to Mac.
282        - FX Sends: Provide more useful error messages on routing problems
283          (see bug #169).
284        - LSCP doc: Be more clear describing the two distinct approaches
285          of using external vs. internal effects (see bug #169).
286        - "optional" class: Fixed comparison operators.
287    
288      * Gigasampler/GigaStudio format engine:
289        - Format extension: If requested by instrument then don't play release
290          trigger sample on note-off events.
291    
292      * SFZ format engine:
293        - Fixed memory leak when releasing samples
294          (fixes bug #307, patch by Jacek Roszkowski)
295        - Fixed potential crash when a sample is shared by more than one region
296          (fixes bug #308, patch by Jacek Roszkowski).
297        - Opcode 'sample': Added support for built-in sample '*silence'
298          (fixes bug #310, patch by Jacek Roszkowski).
299    
300    Version 2.1.0 (25 Nov 2017)
301    
302      * SFZ format engine:
303        - added support for <global>, <master> and #define (patch by Alby M)
304        - Removed code duplication in SFZ file loading code.
305        - Added support for sfz extension opcode 'script' which may be used to
306          load real-time instrument script file (NKSP script language).
307        - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
308        - Fixed unintended volume fade-in of voices under certain conditions.
309        - sfz parser: allow missing space between header and opcode
310    
311      * Gigasampler/GigaStudio format engine:
312        - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
313          cutoff settings.
314        - Got rid of resembling an ancient GSt misbehavior which did not pitch at
315          all if an up-pitch of more than 40 semi tones was requested (I don't
316          think there is any stock gig sound that requires this behavior to
317          resemble its original sound).
318        - Added support for controlling whether the individual EGADSR stages may
319          be aborted (as LinuxSampler extension to the original GigaStudio 4
320          format).
321    
322      * general changes:
323        - fixed printf type errors (mostly in debug messages)
324        - use unique_ptr instead of auto_ptr when building with C++11
325        - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
326          allowing to sort data efficiently in real-time safe manner.
327        - RTList class: added methods for moving/inserting elements to arbitrary
328          position within a list.
329        - RTList class: added method fromPtr() for creating an Iterator object from
330          a raw element pointer.
331        - Attempt to partly fix resetting engine channels vs. resetting engine, an
332          overall cleanup of the Reset*(), ConnectAudioDevice(),
333          DisconnectAudioDevice() API methods would still be desirable though,
334          because the current situation is still inconsistent and error prone.
335        - Active voices are now internally grouped to "Note" objects, instead of
336          being directly assigned to a keyboard key. This allows more fine graded
337          processing of voices, which is i.e. required for certain instrument
338          script features.
339        - Fix: Release trigger voices were not spawned on sustain pedal up
340          (CC #64) events.
341        - Fix: Release trigger voices can now also distinguish correctly between
342          note-off and sustain pedal up events.
343        - All engines: Increased ramp speed of volume smoother and pan smoother
344          (while slow rate of crossfade smoother is preserved) to allow quick
345          volume and pan changes by instrument scripts for instance.
346        - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
347          properly and thus were ignored for certain uses.
348        - Added new C++ API method
349          VirtualMidiDevice::SendChannelPressureToSampler().
350        - windows, 32-bit: fixed potential crashes by making sure the stack in
351          sub threads is 16-byte aligned
352        - fixed numerous compiler warnings
353        - Fixed invalid (note-on) event ID being assigned to new Note objects.
354        - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
355          fixes potential undefined behavior.
356        - Fixed Note object leak when triggering notes on keys which did not
357          have a valid sample mapped (fixes bug #252).
358        - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
359        - linuxsampler binary fix: option --create-instruments-db ignored
360          subsequent optional argument due to glibc's implementation oddity
361          which expects a "=" sign, but no space between them.
362    
363      * packaging changes:
364        - removed unnecessary dependency to libuuid
365          (originated by libgig's usage of it)
366        - Automake: set environment variable GCC_COLORS=auto to allow GCC to
367          auto detect whether it (sh/c)ould output its messages in color.
368        - Debian: Fixed packaging error about invalid "Source-Version"
369          substitution variable.
370        - Debian: Raised Debian compatibility level to Debian 9 "Stretch".
371        - Debian: Added build dependency to libsqlite3-dev for building
372          linuxsampler with instruments DB support.
373    
374      * Real-time instrument scripts:
375        - Implemented scheduler for delayed MIDI events and for suspended scripts.
376        - Built-in script function "wait()": implemented support for function's
377          "duration-us" argument, thus scripts using this function are now
378          correctly resumed after the requested amount of microseconds.
379        - Built-in script function "play_note()": implemented support for
380          function's "duration-us" argument, thus notes triggered with this
381          argument are now correctly released after the requested amount of
382          microseconds.
383        - Fix: script events were not cleared when engine channel was reset,
384          potentially causing undefined behavior.
385        - Fixed crash which happened when trying to reference an undeclared
386          variable.
387        - Built-in script function "play_note()": Added support for passing
388          special value -1 for "duration-us" argument, which will cause the
389          triggered note to be released once the original note was released.
390        - Instrument script classes now exported with the liblinuxsampler C++ API.
391        - Added new API method ScriptVM::syntaxHighlighting() which provides
392          a convenient syntax highlighting backend for external instrument
393          script editor applications.
394        - Added new C++ API class "ScriptVMFactory".
395        - Extended parser issues to provide not only first line and first
396          column, but also last line and last column of issue (thus marking
397          the precise span of the issue within the source code).
398        - Reload script automatically after being modified by an instrument
399          editor.
400        - NKSP language grammar correction: allow empty event handler bodies
401          like "on note end on".
402        - Implemented built-in script function "change_vol()".
403        - Implemented built-in script function "change_tune()".
404        - Implemented built-in script function "change_pan()".

406        - Implemented built-in script function "change_reso()".
407        - Implemented built-in script function "event_status()".
408        - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
409          "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
410          "event_status()" function.
411        - NKSP language: Added support for bitwise operators ".or.", ".and."
412          and ".not.".
413        - NKSP language scanner: Fixed IDs matching to require at least one
414          character (i.e. when matching function names or variable names).
415        - NKSP language scanner: disabled unusued rules.
416        - Fixed behavior of play_note() and note_off() functions which must
417          be distinguished engine internally from "real" MIDI note on/off
418          events in order to avoid misbehaviors like hanging notes.
419        - Implemented built-in script variable "$KSP_TIMER".
420        - Implemented built-in script variable "$NKSP_REAL_TIMER".
421        - Implemented built-in script variable "$NKSP_PERF_TIMER".
422        - Implemented built-in script variable "$ENGINE_UPTIME".
423        - Implemented built-in script function "inc()".
424        - Implemented built-in script function "dec()".
425        - NKSP language fix: division expressions were evaluated too often.
426        - NKSP language fix: string concatenation operator was right
427          associative instead of left (to right).
428        - NKSP language correction: allow empty statements in entire language
429          (i.e. "if end if").
430        - Implemented built-in script function "stop_wait()".
431        - Implemented built-in script variable "$NI_CALLBACK_ID".
432        - Implemented built-in script variable "$NI_CALLBACK_TYPE".
433        - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
434        - Added support for read-only built-in variables (respectively
435          handled by the script parser).
436        - Added built-in script constant "$NI_CB_TYPE_INIT".
437        - Added built-in script constant "$NI_CB_TYPE_NOTE".
438        - Added built-in script constant "$NI_CB_TYPE_RELEASE".
439        - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".
440        - NKSP Language: Added support for user defined script functions.
441        - Implemented built-in script function "change_attack()".
442        - Implemented built-in script function "change_decay()".
443        - Implemented built-in script function "change_release()".
444        - Fixed all change_*() built-in script functions to apply their
445          synthesis parameter changes immediately in case the respective note
446          was triggered at the same time, instead of scheduling the parameter
447          change, especially because it would cause some parameter types's
448          changes either to be ramped (i.e. change_vol()) or other types even
449          to have not effect at all (i.e. change_attack()).
450        - Implemented built-in script function "sh_left()".
451        - Implemented built-in script function "sh_right()".
452        - Implemented built-in script function "min()".
453        - Implemented built-in script function "max()".
454        - NKSP Fix: "init" event handler was not always executed when a script
455          was loaded.
456        - NKSP built-in wait() script function: abort script execution if
457          a negative or zero wait time was passed as argument (since this is
458          a common indication of a bug either of the script or even of the
459          engine, which could lead to RT instability or even worse).
460        - ScriptVM: Implemented automatic suspension of RT safety
461          threatening scripts.
462        - Provide more user friendly error messages on syntax errors.
463        - Fixed NKSP parser warning "Not a statement" when assigning an
464          initializer list to an array variable.
465        - Implemented built-in script array variable "%ALL_EVENTS".
466        - Implemented built-in script function "in_range()".
467        - Implemented built-in script function "change_amp_lfo_depth()".
468        - Implemented built-in script function "change_amp_lfo_freq()".
469        - Implemented built-in script function "change_pitch_lfo_depth()".
470        - Implemented built-in script function "change_pitch_lfo_freq()".
471        - Implemented built-in script function "change_vol_time()".
472        - Implemented built-in script function "change_tune_time()".
473        - Implemented built-in script function "fade_in()".
474        - Implemented built-in script function "fade_out()".
475        - Fixed acceptance of wrong data type of parameters passed to built-in
476          script functions "change_vol()", "change_tune()", "change_pan()",
477          "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
478          "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
479          "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
480        - Added built-in script function "get_event_par()" and implemented some
481          of its possible parameter selections.
482        - Added built-in script function "set_event_par()" and implemented some
483          of its possible parameter selections.
484        - Fixed a bunch of scheduler time related bugs.
485        - Fixed polyphonic variables not being reset to zero after usage.
486        - Built-in "ignore_event()" function: argument is now optional, like with
487          built-in function "ignore_controller()".
488        - Implemented built-in script function "change_velo()".
489        - Implemented built-in script function "change_note()".
490        - Adjusted behavior of "change_vol()" and "change_tune()" to a more
491          intuitive behavior if used in combination with "change_vol_time()" or
492          "change_tune_time()" respectively: now tuning/volume changes are only
493          assigned (without delay) immediately to a new note if the respective
494          timing function has not been called before, otherwise the volume/tuning
495          changes are automatically faded (before, only the event's time stamp was
496          relevant).
497         - Implemented built-in script function "array_equal()".
498         - Implemented built-in script function "search()".
499         - Implemented built-in script function "sort()".
500         - NKSP Fix: Never suspend "init" event handlers.
501         - Implemented built-in script function "same_region()" (currently only
502           available for gig format engine).
503         - Added built-in script constant "$NKSP_LINEAR".
504         - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
505         - Implemented built-in script function "change_vol_curve()".
506         - Implemented built-in script function "change_tune_curve()".
507         - built-in "play_note()" function now supports a sample playback start
508           offset with argument 3, where special value -1 means to use the regular
509           sample offset as defined by the instrument file.
510         - Built-in array variable %KEY_DOWN[] is now a read-only variable.
511         - Built-in variable $EVENT_NOTE is now a read-only variable.
512         - Built-in variable $EVENT_VELOCITY is now a read-only variable.
513         - built-in "play_note()" function now accepts -2 for its fourth argument
514           (note duration) which means the life time of the note shall be sticked
515           to the requested note number of argument 1.
516         - Fix: built-in "play_note()" function now returns 0 as result value if
517           -1 was passed for its fourth argument (note duration) and the respective
518           parent note is already gone.
519        - Implemented built-in script function "change_play_pos()".
520        - NKSP language: Added support for user declared const array variables.
521        - NKSP language: Raise parser warning if array variable is accessed with
522          an index that exceeds the array's size.
523        - NKSP language fix: Unknown characters were not handled correctly.
524        - NKSP language: Added support for "synchronized .. end synchronized"
525          code blocks.
526        - Implemented built-in script function "abort()" which allows to abort
527          another script handler by passing its callback ID.
528        - Fixed potential memory access bug and potential undefined behavior of
529          "init" event handlers.
530        - Print a time stamp along to each call of built-in function "message()".
531        - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
532          to retrieve all code blocks filtered out by the preprocessor.
533        - Added built-in script function "fork()".
534        - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
535        - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
536        - Fixed potential crash when accessing dynamic built-in array variables.
537        - Added built-in script function "callback_status()".
538        - Added built-in constant $CALLBACK_STATUS_TERMINATED.
539        - Added built-in constant $CALLBACK_STATUS_QUEUE.
540        - Added built-in constant $CALLBACK_STATUS_RUNNING.
541        - Removed max. value limitation of built-in functions "change_attack()",
542          "change_decay()" and "change_release()" to i.e. allow passing 2000000
543          for doubling the respective time.
544        - NKSP script editor syntax highlighting API: Fixed app termination due
545          to a lexer start condition stack underrun.
546        - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
547          USE_CODE_IF_NOT() preprocessor statements.
548        - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
549          can be set to disable all subsequent built-in "message()" function calls
550          on preprocessor level.
551        - Implemented built-in script function "change_sustain()".
552        - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
553          to avoid the editor app to crash on ill-formed text input.
554        - Added built-in script function "change_pan_time()".
555        - Added built-in script function "change_pan_curve()".
556        - Added built-in script function "change_cutoff_attack()".
557        - Added built-in script function "change_cutoff_decay()".
558        - Added built-in script function "change_cutoff_sustain()".
559        - Added built-in script function "change_cutoff_release()".
560        - Added built-in script function "change_cutoff_lfo_depth()".
561        - Added built-in script function "change_cutoff_lfo_freq()".
562    
563      * Instruments DB:
564        - Fixed memory access bug of general DB access code which lead to
565          undefined behavior.
566        - Cleanup of instruments DB file creation and opening code.
567        - The instrument DB path of linuxsampler's --create-instruments-db argument
568          is now optional, if it is missing, then a default location is used.
569        - Added support for scanning SFZ (.sfz) files.
570        - Added support for scanning Sound Font (.sf2) files.
571        - Fixed undefined DB transaction behavior.

636        - experimental support for per voice equalization
637        - added command line option --exec-after-init
638        - Introduced new C++ API method:
639          EngineChannel::InstrumentFileName(int index)
640          allowing to retrieve the whole list of files used for the loaded
641          instrument on an engine channel (a.k.a. part). Some GigaStudio
642          instruments for example are splitted over several files like
643          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
644        - Added new C++ API method Sampler::GetGlobalMaxVoices().
645        - Added new C++ API method Sampler::GetGlobalMaxStreams().
646        - Added new C++ API method Sampler::SetGlobalMaxVoices().
647        - Added new C++ API method Sampler::SetGlobalMaxStreams().
648        - Various "const" and "restrict" optimizations.
649        - all engines: add pan CC value to instrument pan parameter before
650          applying panning, instead of using two separate pan functions in
651          series (#182)
652        - added a lock guard class for exception safe mutex handling and
653          used it everywhere appropriate
654        - Immediately apply scale tuning changes to active voices.
655        - Exposed scale tuning to C++ API (along to the already existing standard
656          SysEx way).
657        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
658          and broken for ppc64. (Seq_cst loads and stores are actually not
659          used in LS, so the bug wasn't noticable.)
660        - lsatomic.h: added ARMv7 support
661        - Added support for multiple MIDI input ports per sampler channel (and
662          added various new C++ methods for this new feature / design change, old
663          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
664          as deprecated but are still there and should provide full behavior
665          backward compatibility).
666        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
667          unsafe and caused compilation error with clang 2.x).
668        - Bugfix: only process the latest MIDI program change event.
669        - Introducing the LSCP shell, which provides convenient control of the
670          sampler from the command line by providing LSCP aware features.
671        - VirtualMidiDevice: Added support for program change.
672        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
673        - VirtualMidiDevice: Added support for pitch bend.
674        - Aftertouch: extended API to explicitly handle channel pressure and
675          polyphonic key pressure events (so far polyphonic pressure was not
676          supported at all, and channel pressure was rerouted as CC128 but not
677          used so far).
678        - Added initial support for real-time instrument scripts. The script VM
679          code is shared by all sampler engine implemementations, however only the
680          gig file format currently provides support for storing instrument scripts
681          (as LinuxSampler extension to the original GigaStudio 4 format).
