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

499        - Implemented built-in script function "change_reso()".
500        - Implemented built-in script function "event_status()".
501        - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
502          "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
503          "event_status()" function.
504        - NKSP language: Added support for bitwise operators ".or.", ".and."
505          and ".not.".
506        - NKSP language scanner: Fixed IDs matching to require at least one
507          character (i.e. when matching function names or variable names).
508        - NKSP language scanner: disabled unusued rules.
509        - Fixed behavior of play_note() and note_off() functions which must
510          be distinguished engine internally from "real" MIDI note on/off
511          events in order to avoid misbehaviors like hanging notes.
512        - Implemented built-in script variable "$KSP_TIMER".
513        - Implemented built-in script variable "$NKSP_REAL_TIMER".
514        - Implemented built-in script variable "$NKSP_PERF_TIMER".
515        - Implemented built-in script variable "$ENGINE_UPTIME".
516        - Implemented built-in script function "inc()".
517        - Implemented built-in script function "dec()".
518        - NKSP language fix: division expressions were evaluated too often.
519        - NKSP language fix: string concatenation operator was right
520          associative instead of left (to right).
521        - NKSP language correction: allow empty statements in entire language
522          (i.e. "if end if").
523        - Implemented built-in script function "stop_wait()".
524        - Implemented built-in script variable "$NI_CALLBACK_ID".
525        - Implemented built-in script variable "$NI_CALLBACK_TYPE".
526        - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
527        - Added support for read-only built-in variables (respectively
528          handled by the script parser).
529        - Added built-in script constant "$NI_CB_TYPE_INIT".
530        - Added built-in script constant "$NI_CB_TYPE_NOTE".
531        - Added built-in script constant "$NI_CB_TYPE_RELEASE".

535        - Implemented built-in script function "change_decay()".
536        - Implemented built-in script function "change_release()".
537        - Fixed all change_*() built-in script functions to apply their
538          synthesis parameter changes immediately in case the respective note
539          was triggered at the same time, instead of scheduling the parameter
540          change, especially because it would cause some parameter types's
541          changes either to be ramped (i.e. change_vol()) or other types even
542          to have not effect at all (i.e. change_attack()).
543        - Implemented built-in script function "sh_left()".
544        - Implemented built-in script function "sh_right()".
545        - Implemented built-in script function "min()".
546        - Implemented built-in script function "max()".
547        - NKSP Fix: "init" event handler was not always executed when a script
548          was loaded.
549        - NKSP built-in wait() script function: abort script execution if
550          a negative or zero wait time was passed as argument (since this is
551          a common indication of a bug either of the script or even of the
552          engine, which could lead to RT instability or even worse).
553        - ScriptVM: Implemented automatic suspension of RT safety
554          threatening scripts.
555        - Provide more user friendly error messages on syntax errors.
556        - Fixed NKSP parser warning "Not a statement" when assigning an
557          initializer list to an array variable.
558        - Implemented built-in script array variable "%ALL_EVENTS".
559        - Implemented built-in script function "in_range()".
560        - Implemented built-in script function "change_amp_lfo_depth()".
561        - Implemented built-in script function "change_amp_lfo_freq()".

565        - Implemented built-in script function "change_tune_time()".
566        - Implemented built-in script function "fade_in()".
567        - Implemented built-in script function "fade_out()".
568        - Fixed acceptance of wrong data type of parameters passed to built-in
569          script functions "change_vol()", "change_tune()", "change_pan()",
570          "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
571          "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
572          "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
573        - Added built-in script function "get_event_par()" and implemented some
574          of its possible parameter selections.
575        - Added built-in script function "set_event_par()" and implemented some
576          of its possible parameter selections.
577        - Fixed a bunch of scheduler time related bugs.
578        - Fixed polyphonic variables not being reset to zero after usage.
579        - Built-in "ignore_event()" function: argument is now optional, like with
580          built-in function "ignore_controller()".
581        - Implemented built-in script function "change_velo()".
582        - Implemented built-in script function "change_note()".
583        - Adjusted behavior of "change_vol()" and "change_tune()" to a more
584          intuitive behavior if used in combination with "change_vol_time()" or
585          "change_tune_time()" respectively: now tuning/volume changes are only
586          assigned (without delay) immediately to a new note if the respective
587          timing function has not been called before, otherwise the volume/tuning
588          changes are automatically faded (before, only the event's time stamp was
589          relevant).
590         - Implemented built-in script function "array_equal()".
591         - Implemented built-in script function "search()".
592         - Implemented built-in script function "sort()".

597         - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
598         - Implemented built-in script function "change_vol_curve()".
599         - Implemented built-in script function "change_tune_curve()".
600         - built-in "play_note()" function now supports a sample playback start
601           offset with argument 3, where special value -1 means to use the regular
602           sample offset as defined by the instrument file.
603         - Built-in array variable %KEY_DOWN[] is now a read-only variable.
604         - Built-in variable $EVENT_NOTE is now a read-only variable.
605         - Built-in variable $EVENT_VELOCITY is now a read-only variable.
606         - built-in "play_note()" function now accepts -2 for its fourth argument
607           (note duration) which means the life time of the note shall be sticked
608           to the requested note number of argument 1.
609         - Fix: built-in "play_note()" function now returns 0 as result value if
610           -1 was passed for its fourth argument (note duration) and the respective
611           parent note is already gone.
612        - Implemented built-in script function "change_play_pos()".
613        - NKSP language: Added support for user declared const array variables.

617        - NKSP language: Added support for "synchronized .. end synchronized"
618          code blocks.

620          another script handler by passing its callback ID.
621        - Fixed potential memory access bug and potential undefined behavior of
622          "init" event handlers.
623        - Print a time stamp along to each call of built-in function "message()".
624        - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
625          to retrieve all code blocks filtered out by the preprocessor.
626        - Added built-in script function "fork()".
627        - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
628        - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
629        - Fixed potential crash when accessing dynamic built-in array variables.

634        - Removed max. value limitation of built-in functions "change_attack()",
635          "change_decay()" and "change_release()" to i.e. allow passing 2000000
636          for doubling the respective time.
637        - NKSP script editor syntax highlighting API: Fixed app termination due
638          to a lexer start condition stack underrun.
639        - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
640          USE_CODE_IF_NOT() preprocessor statements.
641        - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
642          can be set to disable all subsequent built-in "message()" function calls
643          on preprocessor level.
644        - Implemented built-in script function "change_sustain()".
645        - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
646          to avoid the editor app to crash on ill-formed text input.
647        - Added built-in script function "change_pan_time()".
648        - Added built-in script function "change_pan_curve()".

657        - Fixed memory access bug of general DB access code which lead to
658          undefined behavior.
659        - Cleanup of instruments DB file creation and opening code.
660        - The instrument DB path of linuxsampler's --create-instruments-db argument
661          is now optional, if it is missing, then a default location is used.
662        - Added support for scanning SFZ (.sfz) files.
663        - Added support for scanning Sound Font (.sf2) files.
664        - Fixed undefined DB transaction behavior.
665

725        - implemented support for internal LADSPA effects
726        - raised limit of program change queue from 100 to 512
727          (as suggested by Alex Stone)
728        - implemented sine LFO, pulse LFO and saw LFO
729        - experimental support for per voice equalization
730        - added command line option --exec-after-init
731        - Introduced new C++ API method:
732          EngineChannel::InstrumentFileName(int index)
733          allowing to retrieve the whole list of files used for the loaded
734          instrument on an engine channel (a.k.a. part). Some GigaStudio
735          instruments for example are splitted over several files like
736          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
737        - Added new C++ API method Sampler::GetGlobalMaxVoices().
738        - Added new C++ API method Sampler::GetGlobalMaxStreams().
739        - Added new C++ API method Sampler::SetGlobalMaxVoices().
740        - Added new C++ API method Sampler::SetGlobalMaxStreams().
741        - Various "const" and "restrict" optimizations.
742        - all engines: add pan CC value to instrument pan parameter before
743          applying panning, instead of using two separate pan functions in
744          series (#182)
745        - added a lock guard class for exception safe mutex handling and
746          used it everywhere appropriate
747        - Immediately apply scale tuning changes to active voices.
748        - Exposed scale tuning to C++ API (along to the already existing standard
749          SysEx way).
750        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
751          and broken for ppc64. (Seq_cst loads and stores are actually not
752          used in LS, so the bug wasn't noticable.)
753        - lsatomic.h: added ARMv7 support
754        - Added support for multiple MIDI input ports per sampler channel (and
755          added various new C++ methods for this new feature / design change, old
756          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
757          as deprecated but are still there and should provide full behavior
758          backward compatibility).
759        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
760          unsafe and caused compilation error with clang 2.x).
761        - Bugfix: only process the latest MIDI program change event.
762        - Introducing the LSCP shell, which provides convenient control of the
763          sampler from the command line by providing LSCP aware features.
764        - VirtualMidiDevice: Added support for program change.
765        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
766        - VirtualMidiDevice: Added support for pitch bend.
767        - Aftertouch: extended API to explicitly handle channel pressure and
768          polyphonic key pressure events (so far polyphonic pressure was not
769          supported at all, and channel pressure was rerouted as CC128 but not
770          used so far).
771        - Added initial support for real-time instrument scripts. The script VM
772          code is shared by all sampler engine implemementations, however only the
773          gig file format currently provides support for storing instrument scripts
774          (as LinuxSampler extension to the original GigaStudio 4 format).

787          min value
788        - Exclusive Groups: don't ever stop voices of the same note,

1158        - fixed crash which occurred when changing an already deployed sampler
1159          channel to a different engine type
1160        - fixed crash when deleting a sampler channel or changing engine
1161          type while an instrument load was in progress
1162        - bugfix: playing a note while changing the instrument could cause
1163          a crash, or give "Handing back unknown region" error messages
1164        - bugfix: calling SET VOICES (which Fantasia does on start and
1165          refresh) could cause instruments to be unloaded
1166        - Mac OS X: fixed name collision of enum in EffectControl and
1167          wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
1168        - Mac OS X: fixed hanging threads
1169        - Windows: disabled the previous thread fix on non-Mac systems, as
1170          it caused hanging threads on Windows
1171        - Fixed possible crashes due to corrupted MIDI/audio device list
1172          after MIDI/audio device creation failure
1173        - When creating MIDI instrument map entries with "PERSISTENT" type, the
1174          instruments were uselessly precached with zero samples, however it still
1175          took the full preloading time and on 1st program change the respective
1176          instrument was completely reloaded again.
1177        - fixed handling of rapid bank select and program change messages
1178          sent to the same sampler channel (patch from the Open Octave
1179          project, slightly adjusted)
1180        - fixed crash when trying to create an effect instance with controls
1181          which min and/or max values depend on the sample rate
1182        - fixed bug #162
1183        - bugfix: LADSPA_PATH was not evaluated correctly when containing
1184          multiple paths (#165)
1185        - thread safety fixes for the instrument loading thread
1186        - bugfix: instrument loading crashed for sfz and sf2 in Ardour
1187          (#176)
1188        - more thread safety fixes for the instrument loading thread
1189        - sfz/sf2 engine: fixed crash when using small audio fragment size
1190        - Mac OS X: fixed crash when unloading plugin on 10.7 and later
1191        - Mac OS X: fixed process hang when unloading 32-bit plugin (bug
1192          introduced in previous fix)
1193        - fixed crash when a channel received a program change while
1194          playing a note in a key group
1195        - fixed erroneous error message piping in VoiceBase.h
1196          (labelled "Disk stream not available in time")
1197        - Update effects on sample rate & period size changes (to avoid
1198          crashes and noise on such transitions).
1199        - ignore missing LADSPA paths without ignoring valid LADSPA paths
1200          (fixes #208)
1201        - Fixed bug in LSCP grammar definition which caused a statement like
1202          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1203          practically irrelevant, however it caused problems with the new LSCP
1204          shell's auto completion feature).
1205        - Fixed MIDI program change messages being ignored if quickly executed
1206          after each other (fixes #231).
