* Preparations for new release (2.3.1).
1 Version 2.3.1 (26 Mar 2024)
3 * general changes:
4 - CoreVMFunctions.cpp: Fixed compiler error with certain C++ stdlib
5 versions (due to const-ness differences with STL's std::sort()
6 implementations).
8 Version 2.3.0 (26 Jan 2024)
10 * general changes:
11 - AbstractEngineChannel: fixed CCs not being forwarded to all
12 VirtualMIDIDevices.
13 - Fix compiler error with release tarball if no Bison installed
14 (SVN version still requires Flex and Bison being installed).
15 - Sampler::Reset() no longer unloads instrument editor plugins, this is a
16 workaround for the issue that instrument editor plugins were no longer
17 available after sending a LSCP "RESET" command (probably due to a race).
19 * Real-time instrument scripts:
20 - Fix: Do not share compiled instrument scripts among multiple engine
21 channels (sampler parts) as this can lead to crashes and would allow the
22 same global script variables to be accessible from multiple engine
23 channels which would not be the expected behaviour by instrument script
24 authors.
26 * GigaStudio/Gigasampler format engine:
27 - Use libgig's new IO-per-thread feature to avoid file I/O concurrency
28 issues with .gig file.
29 - Use libgig's new method gig::File::GetSample() with method
30 gig::File::CountSamples() instead of now deprecated
31 gig::File::GetFirstSample() / gig::File::GetNextSample() pair.
32 - Use libgig's new method gig::Instrument::GetRegionAt() with method
33 gig::Instrument:CountRegions() instead of now deprecated
34 gig::Instrument::GetFirstRegion() / gig::Instrument::GetNextRegion() pair.
35 - Use libgig's gig::File::GetInstrument() method with method
36 gig::File::CountInstruments() instead of now deprecated
37 gig::File::GetFirstInstrument() / gig::File::GetNextInstrument() pair.
38 - Show a more detailed error message on terminal if an appropriate editor
39 could not be found for a .gig instrument (if there is not any editor then
40 say so, if there is one but not capable to handle the instrument, then
41 make this case clear to the user; in both cases print the expected
42 location for instrument editor plugins).
43 - Fixed wrong velocity for release triggered samples: if and only if
44 note-off velocity is exactly zero (which means MIDI keyboard does not have
45 release velocity sensors) then use previous note-on velocity as note-off
46 velocity for release triggered samples instead.
48 * SFZ format engine:
49 - Fixed wrong velocity for release triggered samples: if and only if
50 note-off velocity is exactly zero (which means MIDI keyboard does not have
51 release velocity sensors) then use previous note-on velocity as note-off
52 velocity for release triggered samples instead.
53 - sfz.h: Added File::filename() method.
54 - sfz.h: Added File::checkFileModified() method allowing to detect file
55 changes (e.g. by other apps).
56 - sfz.h: Added Instrument::GetFile() method.
57 - Automatically reload .sfz files on file changes (e.g. by some external
58 text editor).
60 * MIDI driver:
61 - VirtualMidiDevice: added method Reset() which is e.g. intended to be used
62 in "panic" / MIDI "all sound off" / MIDI "all note off" situations.
63 - VirtualMidiDevice: release all notes on MIDI CC #120 and CC #123.
65 Version 2.2.0 (9 May 2021)
67 * general changes:
68 - Fixed compiler error in Pool.h.
69 - Require C++14 compiler support.
70 - Autoconf: Added m4/ax_cxx_compile_stdcxx.m4 macro which is used
71 for checking in configure for C++14 support (as mandatory
72 requirement) and automatically adds compiler argument if required
73 (e.g. -std=C++14).
74 - RTMath: Implemented floating point comparison methods
75 fEqual32(float,float) and fEqual64(double,double) which take the
76 expected floating point tolerances into account.
77 - Added public API C++ class "LFO", which is a cluster class encapsulating
78 all the sampler's LFO implementations to be used by 3rd party applications
79 (e.g. by Gigedit).
80 - Added int math square LFO implementation.
81 - Added int math saw LFO implementation.
82 - Added numeric complex nr sine LFO implementation.
83 - Marked class LFOTriangleDiHarmonic as deprecated
84 (will be removed in future).
85 - Added LFOAll.h which includes all LFO implementation's header files.
86 - Refactored LFO class names and their file names (PulseLFO -> LFOPulse,
87 LFOSawIntMath -> LFOSawIntMathNew, SawLFO -> LFOSawIntMathOld,
88 SineLFO -> LFOSineBuiltinFn, LFOSine -> LFOSineNumericComplexNr,
89 SquareLFO -> LFOSquarePulse and separated the latter to its own header
90 file).
91 - Renamed type LFOSigned -> LFOTriangleSigned.
92 - Renamed type LFOUnsigned -> LFOTriangleUnsigned.
93 - Using now cubic interpolation as resampling algorithm by default; and
94 linear interpolation is deprecated now.
95 - Event:Init(): memset() entire Event::Param union to zero instead of trying
96 to do that for its individual members; the latter became error prone due
97 to the union's growing complexity meanwhile.
98 - EngineChannel: Overhaul of RPN/NRPN related methods: Added new
99 *Rpn*Parameter*() methods as replacement for previous *Rpn*Controller*()
100 methods and marked the old ones as deprecated; and likewise added new
101 *Nrpn*Parameter*() methods as replacement for previous *Nrpn*Controller*()
102 methods and marked those old ones deprecated as well.
103 - Added support for MIDI CC #38 (data entry LSB): this allows higher value
104 resolution for certain (e.g. hard coded) RPN and NRPN parameters.
105 - Implemented support for compressed RPN/NRPN message sequences (that is to
106 allow processing MIDI data entry messages without always having to be
107 preceded strictly by RPN/NRPN parameter selection messages on each value
108 change).
109 - Added support for MIDI CC #96 (data increment) and MIDI CC #97 (data
110 decrement).
111 - Added support for 'null function RPN/NRPN' (which is RPN/NRPN parameter
112 MSB=127 and LSB=127) and which is disabling subsequent data
113 entry/increment/decrement CC messages.
114 - Fixed crash when editing key groups (a.k.a. exclusive groups) with an
115 instrument editor.
116 - Fixed playing noise at the end of a disk stream under certain conditions.
117 - Fixed potential crash with high pitch at end of RAM playback.
118 - Added configure checks whether C++ compiler supports so called
119 'designated initializers'.
120 - Added global backtraceAsString() function for debugging purposes
121 (POSIX systems only, no Windows implementation yet).
122 - Thread class: Added new methods pushCancelable(), popCancelable(), name(),
123 nameOfCaller() and setNameOfCaller().
124 - configure: Always check for availability of pthread_testcancel() and use
125 it if so (previously it was only used if explicitly enabled by configure
126 option).
127 - Thread class: raise compiler warning if pthread_testcancel() is not
128 available, because it can lead to deadlocks.
129 - Mutex class: Implemented optional bug detection and deadlock debugging
130 features.
131 - Ref<> class is now thread safe (as lock-free and wait-free
132 implementation).
133 - Fixed compilation error with Bison >= 3.6.0.
134 - Fixed rare crash when switching between instruments that had instrument
135 scripts loaded.
136 - Allow EffectChain::InsertEffect() as alternative to
137 EffectChain::AppendEffect() (i.e. with index equal to current chain size).
138 - ConstCapacityArray class: Fixed bug in remove() method.
139 - Fixed crash on certain MIDI RPN and NRPN messages that occurred if no
140 real-time instrument script was loaded.
142 * Real-time instrument scripts:
143 - Added method ScriptVM::setExitResultEnabled() which allows to
144 explicitly enable the built-in exit() function to optionally accept
145 one function argument; the value of the passed exit() function
146 argument will then become available by calling
147 VMExecContext::exitResult() after script execution.
148 - 64 bit support for NKSP integer scripts variables (declare $foo).
149 - Variable names, function names and preprocessor condition names must start
150 with a regular character (a-z or A-Z); starting them with a digit or
151 underscore is not allowed.
152 - NKSP parser fix: equal comparison operator "=" and not equal comparison
153 operator "#" must only accept integer operands.
154 - NKSP language: Implemented support for standard units like Hertz, seconds,
155 Bel including support for metric unit prefixes; so one can now e.g.
156 conveniently use numbers in scripts like "5us" meaning "5 microseconds",
157 or e.g. "12kHz" meaning "12 kilo Hertz", or e.g. "-14mdB" meaning
158 "minus 14 Millidecibel", or e.g. "28c" meaning "28 cents" (for tuning).
159 - NKSP language: Introduced "final" operator "!" which is specifically
160 intended for synthesis parameter values to denote that the synthesis
161 parameter value is intended to be the "final" value for that synthesis
162 parameter that should explicitly be used by the engine and thus causing
163 the sampler engine to ignore all other modulation sources for the same
164 synthesis parameter (like e.g. LFO, EG); by simply prefixing a value,
165 variable or formula with this new "!" operator the expression is marked as
166 being "final".
167 - NKSP script editor API: Added support for detecting standard unit tokens
168 and their potential metric prefix token.
169 - NKSP language: Added support for NKSP real number literals and
170 arithmetic operations on them (e.g. "(3.9 + 2.9) / 12.3 - 42.0").
171 - NKSP language: Added support for NKSP real number (floating point) script
172 variables (declare ~foo).
173 - NKSP language: Added support for NKSP real number (floating point) array
174 script variables (declare ?foo[]).
175 - Built-in script function "message()" accepts now real number argument as
176 well.
177 - Added built-in script function "real_to_int()" and its short hand form
178 "int()" for casting from real number to integer in NKSP scripts.
179 - Added built-in script function "int_to_real()" and its short hand form
180 "real()" for casting from integer to real number in NKSP scripts.
181 - Allow built-in exit() function to potentially accept real number type
182 argument as well.
183 - Built-in script functions may have a different return type depending on
184 the arguments passed to the function.
185 - Built-in script function "abs()" optionally accepts and returns real
186 number.
187 - Built-in script functions "min()" and "max()" optionally accept real
188 number arguments and return real number as result in that case.
189 - NKSP VM API: Allow units and 'final'ness to be returned as result from
190 built-in functions (added methods VMFunction::returnUnitType() and
191 VMFunction::returnsFinal() for that purpose which must be implemented by
192 built-in function implementations).
193 - NKSP language: Allow metric unit prefixes of numeric scalar and array
194 variables to be changed freely at runtime (unlike unit types like Hz etc.
195 which are still sticky, parse-time features of variables which cannot be
196 changed at runtime for the intentional sake of determinism).
197 - NKSP language: 'final' values are prohibited for array variables for now
198 (attempt causes a parsers error).
199 - NKSP language: expressions with unit types (e.g. Hz) are prohibited for
200 conditions of runtime control structures like if(), while(), select()
201 (attempt causes a parser error).
202 - NKSP VM API: Allow built-in functions to perform their own, individual
203 parse time checks of arguments going to be passed to the function at
204 runtime (added method VMFunction::checkArgs() for that purpose).
205 - NKSP language: raise parser warning if only one operand of binary
206 operators (like logical 'or' comparison) contain a 'final' value (because
207 it would always yield in a 'final' result in such cases).
208 - NKSP language: Allow comparison (=, #, <, >, <=, >=) of values with
209 different metric unit prefixes, which will behave as expected (e.g.
210 result of expression '1000us < 2ms' is true).
211 - NKSP language: Allow adding values with different metric unit prefixes
212 (e.g. result of expression '100Hz + 5kHz' is '5100Hz').
213 - NKSP language: Allow subtracting values with different metric unit
214 prefixes (e.g. result of expression '1ms - 20us' is '980us').
215 - NKSP language: Allow multiplying with any metric unit prefixes
216 (e.g. result of expression '2k * 3ms' is '6s'), however multiplications
217 with unit types on both sides (e.g. '2s * 2s') is still prohibited since
218 we don't have any considerable practical use for a term like '4s^2'
219 (hence any attempt multiplying two unit types still causes parser error).
220 - NKSP language: Allow dividing by any metric unit prefixes and allow
221 division of same unit type on both sides (e.g. expression '8kHz / 1000Hz'
222 yields in unit free result '8'). So this is now a way to cast units away
223 e.g. for passing the result to other expressions, certain function calls
224 or variables which are not accepting any units (or that specific unit).
225 - NKSP language: integer arrays and real number arrays can now be converted
226 to strings (e.g. for dumping their content with message() calls for
227 script debugging purposes).
228 - NKSP language: expressions and variables with units are now correctly
229 casted to strings (e.g. with message() calls).
230 - NKSP language: comparing real numbers for equalness (e.g. '~foo = 3.1') or
231 unequalness (e.g. '~foo # 3.1') is now less strict and takes the expected
232 floating point tolerances into account.
233 - NKSP VM API: Added methods VMScalarNumberExpr::evalCastInt() and
234 VMScalarNumberExpr::evalCastReal().
235 - NKSP VM API: Added base class 'VMNumberArrayExpr' for classes
236 'VMIntArrayExpr' and 'VMRealArrayExpr'.
237 - NKSP VM API: replaced all unitPrefix() (parse time) methods by
238 unitFactor() (runtime) methods.
239 - Built-in function "exit()" supports now returning units and 'final'ness
240 for test cases.
241 - The following built-in functions support now units as well: "abs()",
242 "random()", "inc()", "dec()", "in_range()", "min()", "max()",
243 "real_to_int()", "int()", "int_to_real()" and "real()".
244 - Built-in functions "array_equal()", "search()" and "sort()" support now
245 real number arrays (correctly) as well.
246 - Added individual parse time checks of arguments to be passed to built-in
247 functions "random()", "inc()", "dec()", "in_range()", "min()", "max()",
248 "array_equal()" and "search()" specific for their individual purposes.
249 - NKSP VM refactoring: Renamed all methods, functions and classes matching
250 pattern *ScalarNumber* to simply *Number* (that is i.e. classes
251 VMScalarNumberExpr -> VMNumberExpr, ScalarNumberExpr -> NumberExpr,
252 ScalarNumberVariable -> NumberVariable, ScalarNumberBinaryOp ->
253 NumberBinaryOp, VMScalarNumberResultFunction -> VMNumberResultFunction,
254 method VMExpr::asScalarNumberExpr() -> VMExpr::asNumber(), function
255 isScalarNumber() -> isNumber()).
256 - NKSP VM API: Added 4 overridden methods to class VMNumberExpr:
257 evalCastInt(MetricPrefix_t), evalCastInt(MetricPrefix_t,MetricPrefix_t),
258 evalCastReal(MetricPrefix_t), evalCastReal(MetricPrefix_t,MetricPrefix_t)
259 as convenient methods for automatically converting values to expected
260 metric value basis.
261 - Built-in function "wait()" accepts now both integers and real numbers as
262 argument.
263 - NKSP VM API cleanup: Get rid of legacy method
264 VMFunction::argType(vmint iArg) which was already superseded by its new
265 replacement VMFunction::acceptsArgType(vmint iArg, ExprType_t type).
266 - NKSP parser: if wrong argument type was passed to a built-in function and
267 that built-in function accepts more than one data type for the argument,
268 then show all supported data types as parser error message.
269 - Built-in function "play_note()" accepts now real numbers and seconds as
270 unit type as well for its 3rd and 4th function arguments.
271 - The following built-in functions accept now real numbers as well for their
272 2nd function argument: "change_vol()", "change_tune()", "change_cutoff()",
273 "change_attack()", "change_decay()", "change_release()",
274 "change_sustain()", "change_cutoff_attack()", "change_cutoff_decay()",
275 "change_cutoff_sustain()", "change_cutoff_release()",
276 "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
277 "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
278 "change_pan_time()", "fade_in()", "fade_out()", "change_play_pos()".
279 - Fixed built-in function "change_play_pos()" not having accepted metric
280 prefixes at all.
281 - Fixed the following built-in functions having misinterpreted values given
282 with unit type (for their 2nd argument) as if they were relative values
283 (that is as if they were passed without a unit type): "change_attack()",
284 "change_decay()", "change_release()", "change_cutoff_attack()",
285 "change_cutoff_decay()", "change_cutoff_release()".
286 - Fixed the following built-in functions having applied completely wrong
287 'final' values: "change_sustain()", "change_cutoff_sustain()" (since the
288 respective EGs being their modulation sink assume uint data type with
289 value range 0..1000 instead of 0.0..1.0.
290 - Added individual parse-time checks of function arguments for the following
291 built-in functions: "play_note()", "note_off()", "set_event_mark()",
292 "delete_event_mark()", "by_marks()", "change_cutoff()", "change_attack()",
293 "change_decay()", "change_release()", "change_cutoff_attack()",
294 "change_cutoff_decay()", "change_cutoff_release()",
295 "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
296 "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()" and
297 "change_pan_time()".
298 - Don't abort function call if unit type was used and at the same time
299 'final' operator was omitted for the primary value argument of the
300 following built-in functions: "change_cutoff()", "change_attack()",
301 "change_decay()", "change_release()", "change_cutoff_attack()",
302 "change_cutoff_decay()", "change_cutoff_release()",
303 "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
304 "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
305 "change_pan_time()", instead imply 'final'ness at runtime and raise an
306 appropriate parser warning at parse time.
307 - Added built-in real number functions "round()", "ceil()", "floor()",
308 "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()", "sin()",
309 "cos()", "tan()", "asin()", "acos()", "atan()".
310 - Added built-in script real number constant "~NI_MATH_PI".
311 - Added built-in script real number constant "~NI_MATH_E".
312 - NKSP language: Allow unary '+' operator.
313 - Added built-in script functions "msb()" and "lsb()".
314 - NKSP language: Added support for RPN event handler
315 ("on rpn ... end on" in instrument scripts).
316 - NKSP language: Added support for NRPN event handler
317 ("on nrpn ... end on" in instrument scripts).
318 - Added built-in read-only variables "$RPN_ADDRESS" and "$RPN_VALUE" which
319 may be read from the new RPN/NRPN script handlers to get the (N)RPN
320 parameter that had been changed and its new value.
321 - Added built-in const variables "$NI_CB_TYPE_RPN" and "$NI_CB_TYPE_NRPN"
322 which are identifying the new (N)RPN handlers as such at script runtime.
323 - Implemented built-in script function "set_rpn()".
324 - Implemented built-in script function "set_nrpn()".
325 - Fix: built-in functions returning an array type were broken and caused a
326 crash when the built-in function's (supposed to be array) result value was
327 used by the script VM.
328 - Removed upper value constraint for 2nd argument of built-in functions
329 "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
330 "change_pitch_lfo_freq()","change_reso()", "change_cutoff()",
331 "change_amp_lfo_depth()", "change_cutoff_lfo_depth()" and
332 "change_pitch_lfo_depth()", to allow e.g. passing value 2000000 to double
333 the LFO frequency / resonance / cutoff frequency.
334 - Reduced code involved for parsing NKSP variable declarations by using 2
335 generalized grammar rules with optional components (i.e. optional value
336 assignment and optional variable qualifiers) instead of previous linear
337 combinations of grammar rules, which also fixes some edge case.
338 - NKSP language parser: track code block locations also by a) raw byte
339 position in NKSP source code string and b) length of that code block in
340 bytes (along to the already existing code block tracking by line/column);
341 and added appropriate new members to public C++ API classes like
342 'firstByte' and 'lengthBytes' to class VMSourceToken and struct CodeBlock.
343 - NKSP language: Added support for 'patch' variable qualifier (capture their
344 locations and allow replacement of their assignment expression via VM C++
345 API).
346 - Fixed incorrect EG times if standard measuring unit was passed to built-in
347 functions "change_attack()", "change_decay()" or "change_release()".
348 - Fixed intermediate function result values never having reflected any
349 standard measuring unit type.
350 - Fixed re-entrant issue with function calls which caused wrong result
351 values if the same function was called multiple times in a term
352 (specifically if metric prefixes were used).
353 - NKSP language: Just throw a warning, not an error if an array variable of
354 size zero was declared.
355 - NKSP language: Allow omitting explicit array size on array variable
356 declaration if combined with immediate value assignment
357 (e.g. declare %foo[] := ( 1, 2, 3 ) ).
358 - NKSP language: emit warning if an array variable was declared with bigger
359 array size than amount of initial values been assigned, and initialize the
360 missing array elements with zero in this case.
361 - Fixed built-in NKSP exit() function to behave as return statement.
362 - NKSP parser: Fixed crash if unary '-' operator was used on a non-number
363 data type.
364 - NKSP VM: Fixed the "release" handler being executed too often under
365 certain situations if polyphonic data was passed from "note" handler to
366 "release" handler.
367 - Fixed memory leak in NKSP parser: string tokens were allocated as C
368 strings and never freed.
369 - Fixed incorrect polyphonic data transfer from wrong note handler to
370 release handler; which also fixes no release handler being executed
371 sometimes, and due to the latter it also fixes potential crashes as some
372 polyphonic script events were never released and the engine hence was
373 running out of free script events.
374 - Fixed crash when handling array results of built-in functions
375 (e.g. "num_elements(by_marks($MARK_1)").
376 - NKSP VM: Fixed dead note events not been removed from user's event groups
377 (i.e. causing incorrect behaviour of built-in NKSP functions by_marks()
378 and set_event_mark() after max. size of event group list was exhausted).
380 * test cases:
381 - Fixed compiler errors in test cases.
382 - Updated README for how to compile & run test cases.
383 - Updated test case
384 MutexTest::testDoubleLockStillBlocksConcurrentThread() to latest
385 expected behaviour of the Mutex class implementation (recursive
386 mutex type).
387 - Added test cases for NKSP core language aspects and core built-in
388 functions.
389 - Fixed thread tests segfaulting on Linux.
390 - NKSP: Added real number test cases for built-in functions exit(),
391 int_to_real(), real(), real_to_int() and int(), as well as for the
392 plus, minus and negate language operators.
393 - Added massive amount of NKSP test cases for standard measuring units and
394 'final' operator usage cases.
395 - Added NKSP test cases for (floating point tolerance aware) real number
396 equalness / unequalness comparison.
397 - Added NKSP int array and real array tests for value assignment and
398 initialization of arrays.
399 - Added NKSP test cases for built-in functions "round()", "ceil()",
400 "floor()", "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()",
401 "sin()", "cos()", "tan()", "asin()", "acos()", "atan()".
402 - Added NKSP test cases for unary '+' operator.
403 - Added NKSP test cases for core built-in variables.
404 - Added thorough NKSP test cases for variable declarations.
406 * GigaStudio/Gigasampler format engine:
407 - LFOTriangleIntMath and LFOTriangleIntAbsMath: Fixed FlipPhase=true
408 behaviour for start_level_mid.
409 - Changed LFO start levels: LFO1 and LFO2 both to mid, LFO3 to max. start
410 level (see discussion "GigaStudio LFO compatibility" on mailing list
411 from 2019-09-26 for details).
412 - Changed default wave form for all 3 LFOs to sine (instead of triangle;
413 see discussion "GigaStudio LFO compatibility" on mailing list from
414 2019-09-26 for details).
415 - Format extension: Added support for different LFO wave forms (currently
416 either sine [default], triangle, saw or square).
417 - Format extension: Added support for LFO phase displacement (0��..360��).
418 - Format extension: Added support for flipping LFO polarity on LFO 3
419 (in the original gig format this was only available for LFO 1 and LFO 2).
420 - Format extension: Support for additional filter types:
421 lowpass 1/2/4/6-pole, highpass 1/2/4/6-pole, bandpass 2-pole,
422 bandreject 2-pole.
423 - Fixd potential crash with polynomial interpolator and max. pitch.
424 - If minimum cutoff is defined, remap cutoff controller CC values to really
425 span the entire possible cutoff range (and avoiding a dead controller
426 zone).
427 - Implemented support for loading instrument scripts with 'patch' variables
428 (by patching these script variables with potentially overridden ones by
429 gig Instrument).
431 * SFZ format engine:
432 - Fixed support for regions with loccN/hiccN conditions on more than one
433 MIDI controller.
434 - Fixed internal opcode 'xfin_hivel' falsely being set by user opcode
435 'xfin_lovel' (patch by Christian Czezatke).
437 * Benchmarks:
438 - Fixed benchmarks/triang.cpp falsely having favoured "int math abs"
439 algorithm (since result of 2nd run was not accumulated).
440 - Added benchmark for saw wave (benchmarks/saw.cpp).
441 - Added benchmark for sine wave (benchmarks/sine.cpp).
442 - Added benchmark for square wave (benchmarks/square.cpp).
443 - Increased amount of benchmarks runs by factor 6 to achieve benchmark times
444 which are large enough on modern systems.
446 Version 2.1.1 (27 Jul 2019)
448 * Real-time instrument scripts:
449 - Fixed behavior of built-in NKSP functions change_sustain(),
450 change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain()
451 and change_cutoff_release().
453 * general changes:
454 - Only play release trigger samples on sustain pedal up if this behaviour
455 was explicitly requested by the instrument (otherwise only on note-off).
456 - Fixed compiler warnings.
457 - Fixed compilation error when cross-compiling to Mac.
458 - FX Sends: Provide more useful error messages on routing problems
459 (see bug #169).
460 - LSCP doc: Be more clear describing the two distinct approaches
461 of using external vs. internal effects (see bug #169).
462 - "optional" class: Fixed comparison operators.
464 * Gigasampler/GigaStudio format engine:
465 - Format extension: If requested by instrument then don't play release
466 trigger sample on note-off events.
468 * SFZ format engine:
469 - Fixed memory leak when releasing samples
470 (fixes bug #307, patch by Jacek Roszkowski)
471 - Fixed potential crash when a sample is shared by more than one region
472 (fixes bug #308, patch by Jacek Roszkowski).
473 - Opcode 'sample': Added support for built-in sample '*silence'
474 (fixes bug #310, patch by Jacek Roszkowski).
476 Version 2.1.0 (25 Nov 2017)
478 * SFZ format engine:
479 - added support for <global>, <master> and #define (patch by Alby M)
480 - Removed code duplication in SFZ file loading code.
481 - Added support for sfz extension opcode 'script' which may be used to
482 load real-time instrument script file (NKSP script language).
483 - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
484 - Fixed unintended volume fade-in of voices under certain conditions.
485 - sfz parser: allow missing space between header and opcode
487 * Gigasampler/GigaStudio format engine:
488 - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
489 cutoff settings.
490 - Got rid of resembling an ancient GSt misbehavior which did not pitch at
491 all if an up-pitch of more than 40 semi tones was requested (I don't
492 think there is any stock gig sound that requires this behavior to
493 resemble its original sound).
494 - Added support for controlling whether the individual EGADSR stages may
495 be aborted (as LinuxSampler extension to the original GigaStudio 4
496 format).
498 * general changes:
499 - fixed printf type errors (mostly in debug messages)
500 - use unique_ptr instead of auto_ptr when building with C++11
501 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
502 allowing to sort data efficiently in real-time safe manner.
503 - RTList class: added methods for moving/inserting elements to arbitrary
504 position within a list.
505 - RTList class: added method fromPtr() for creating an Iterator object from
506 a raw element pointer.
507 - Attempt to partly fix resetting engine channels vs. resetting engine, an
508 overall cleanup of the Reset*(), ConnectAudioDevice(),
509 DisconnectAudioDevice() API methods would still be desirable though,
510 because the current situation is still inconsistent and error prone.
511 - Active voices are now internally grouped to "Note" objects, instead of
512 being directly assigned to a keyboard key. This allows more fine graded
513 processing of voices, which is i.e. required for certain instrument
514 script features.
515 - Fix: Release trigger voices were not spawned on sustain pedal up
516 (CC #64) events.
517 - Fix: Release trigger voices can now also distinguish correctly between
518 note-off and sustain pedal up events.
519 - All engines: Increased ramp speed of volume smoother and pan smoother
520 (while slow rate of crossfade smoother is preserved) to allow quick
521 volume and pan changes by instrument scripts for instance.
522 - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
523 properly and thus were ignored for certain uses.
524 - Added new C++ API method
525 VirtualMidiDevice::SendChannelPressureToSampler().
526 - windows, 32-bit: fixed potential crashes by making sure the stack in
527 sub threads is 16-byte aligned
528 - fixed numerous compiler warnings
529 - Fixed invalid (note-on) event ID being assigned to new Note objects.
530 - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
531 fixes potential undefined behavior.
532 - Fixed Note object leak when triggering notes on keys which did not
533 have a valid sample mapped (fixes bug #252).
534 - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
535 - linuxsampler binary fix: option --create-instruments-db ignored
536 subsequent optional argument due to glibc's implementation oddity
537 which expects a "=" sign, but no space between them.
539 * packaging changes:
540 - removed unnecessary dependency to libuuid
541 (originated by libgig's usage of it)
542 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
543 auto detect whether it (sh/c)ould output its messages in color.
544 - Debian: Fixed packaging error about invalid "Source-Version"
545 substitution variable.
546 - Debian: Raised Debian compatibility level to Debian 9 "Stretch".
547 - Debian: Added build dependency to libsqlite3-dev for building
548 linuxsampler with instruments DB support.
550 * Real-time instrument scripts:
551 - Implemented scheduler for delayed MIDI events and for suspended scripts.
552 - Built-in script function "wait()": implemented support for function's
553 "duration-us" argument, thus scripts using this function are now
554 correctly resumed after the requested amount of microseconds.
555 - Built-in script function "play_note()": implemented support for
556 function's "duration-us" argument, thus notes triggered with this
557 argument are now correctly released after the requested amount of
558 microseconds.
559 - Fix: script events were not cleared when engine channel was reset,
560 potentially causing undefined behavior.
561 - Fixed crash which happened when trying to reference an undeclared
562 variable.
563 - Built-in script function "play_note()": Added support for passing
564 special value -1 for "duration-us" argument, which will cause the
565 triggered note to be released once the original note was released.
566 - Instrument script classes now exported with the liblinuxsampler C++ API.
567 - Added new API method ScriptVM::syntaxHighlighting() which provides
568 a convenient syntax highlighting backend for external instrument
569 script editor applications.
570 - Added new C++ API class "ScriptVMFactory".
571 - Extended parser issues to provide not only first line and first
572 column, but also last line and last column of issue (thus marking
573 the precise span of the issue within the source code).
574 - Reload script automatically after being modified by an instrument
575 editor.
576 - NKSP language grammar correction: allow empty event handler bodies
577 like "on note end on".
578 - Implemented built-in script function "change_vol()".
579 - Implemented built-in script function "change_tune()".
580 - Implemented built-in script function "change_pan()".
581 - Implemented built-in script function "change_cutoff()".
582 - Implemented built-in script function "change_reso()".
583 - Implemented built-in script function "event_status()".
584 - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
585 "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
586 "event_status()" function.
587 - NKSP language: Added support for bitwise operators ".or.", ".and."
588 and ".not.".
589 - NKSP language scanner: Fixed IDs matching to require at least one
590 character (i.e. when matching function names or variable names).
591 - NKSP language scanner: disabled unusued rules.
592 - Fixed behavior of play_note() and note_off() functions which must
593 be distinguished engine internally from "real" MIDI note on/off
594 events in order to avoid misbehaviors like hanging notes.
595 - Implemented built-in script variable "$KSP_TIMER".
596 - Implemented built-in script variable "$NKSP_REAL_TIMER".
597 - Implemented built-in script variable "$NKSP_PERF_TIMER".
598 - Implemented built-in script variable "$ENGINE_UPTIME".
599 - Implemented built-in script function "inc()".
600 - Implemented built-in script function "dec()".
601 - NKSP language fix: division expressions were evaluated too often.
602 - NKSP language fix: string concatenation operator was right
603 associative instead of left (to right).
604 - NKSP language correction: allow empty statements in entire language
605 (i.e. "if end if").
606 - Implemented built-in script function "stop_wait()".
607 - Implemented built-in script variable "$NI_CALLBACK_ID".
608 - Implemented built-in script variable "$NI_CALLBACK_TYPE".
609 - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
610 - Added support for read-only built-in variables (respectively
611 handled by the script parser).
612 - Added built-in script constant "$NI_CB_TYPE_INIT".
613 - Added built-in script constant "$NI_CB_TYPE_NOTE".
614 - Added built-in script constant "$NI_CB_TYPE_RELEASE".

617 - Implemented built-in script function "change_attack()".
618 - Implemented built-in script function "change_decay()".
619 - Implemented built-in script function "change_release()".
620 - Fixed all change_*() built-in script functions to apply their
621 synthesis parameter changes immediately in case the respective note
622 was triggered at the same time, instead of scheduling the parameter
623 change, especially because it would cause some parameter types's
624 changes either to be ramped (i.e. change_vol()) or other types even
625 to have not effect at all (i.e. change_attack()).
626 - Implemented built-in script function "sh_left()".
627 - Implemented built-in script function "sh_right()".
628 - Implemented built-in script function "min()".
629 - Implemented built-in script function "max()".
630 - NKSP Fix: "init" event handler was not always executed when a script
631 was loaded.
632 - NKSP built-in wait() script function: abort script execution if
633 a negative or zero wait time was passed as argument (since this is
634 a common indication of a bug either of the script or even of the
635 engine, which could lead to RT instability or even worse).
636 - ScriptVM: Implemented automatic suspension of RT safety
637 threatening scripts.
638 - Provide more user friendly error messages on syntax errors.
639 - Fixed NKSP parser warning "Not a statement" when assigning an
640 initializer list to an array variable.

642 - Implemented built-in script function "in_range()".
643 - Implemented built-in script function "change_amp_lfo_depth()".
644 - Implemented built-in script function "change_amp_lfo_freq()".
645 - Implemented built-in script function "change_pitch_lfo_depth()".
646 - Implemented built-in script function "change_pitch_lfo_freq()".
647 - Implemented built-in script function "change_vol_time()".
648 - Implemented built-in script function "change_tune_time()".
649 - Implemented built-in script function "fade_in()".
650 - Implemented built-in script function "fade_out()".
651 - Fixed acceptance of wrong data type of parameters passed to built-in
652 script functions "change_vol()", "change_tune()", "change_pan()",
653 "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
654 "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
655 "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
656 - Added built-in script function "get_event_par()" and implemented some
657 of its possible parameter selections.
658 - Added built-in script function "set_event_par()" and implemented some
659 of its possible parameter selections.
660 - Fixed a bunch of scheduler time related bugs.
661 - Fixed polyphonic variables not being reset to zero after usage.
662 - Built-in "ignore_event()" function: argument is now optional, like with
663 built-in function "ignore_controller()".
664 - Implemented built-in script function "change_velo()".
665 - Implemented built-in script function "change_note()".
666 - Adjusted behavior of "change_vol()" and "change_tune()" to a more
667 intuitive behavior if used in combination with "change_vol_time()" or
668 "change_tune_time()" respectively: now tuning/volume changes are only
669 assigned (without delay) immediately to a new note if the respective
670 timing function has not been called before, otherwise the volume/tuning
671 changes are automatically faded (before, only the event's time stamp was
672 relevant).
673 - Implemented built-in script function "array_equal()".
674 - Implemented built-in script function "search()".
675 - Implemented built-in script function "sort()".
676 - NKSP Fix: Never suspend "init" event handlers.
677 - Implemented built-in script function "same_region()" (currently only
678 available for gig format engine).
679 - Added built-in script constant "$NKSP_LINEAR".
680 - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
681 - Implemented built-in script function "change_vol_curve()".
682 - Implemented built-in script function "change_tune_curve()".
683 - built-in "play_note()" function now supports a sample playback start
684 offset with argument 3, where special value -1 means to use the regular
685 sample offset as defined by the instrument file.
686 - Built-in array variable %KEY_DOWN[] is now a read-only variable.
687 - Built-in variable $EVENT_NOTE is now a read-only variable.
688 - Built-in variable $EVENT_VELOCITY is now a read-only variable.
689 - built-in "play_note()" function now accepts -2 for its fourth argument
690 (note duration) which means the life time of the note shall be sticked
691 to the requested note number of argument 1.
692 - Fix: built-in "play_note()" function now returns 0 as result value if
693 -1 was passed for its fourth argument (note duration) and the respective
694 parent note is already gone.
695 - Implemented built-in script function "change_play_pos()".
696 - NKSP language: Added support for user declared const array variables.
697 - NKSP language: Raise parser warning if array variable is accessed with
698 an index that exceeds the array's size.
699 - NKSP language fix: Unknown characters were not handled correctly.
700 - NKSP language: Added support for "synchronized .. end synchronized"
701 code blocks.
702 - Implemented built-in script function "abort()" which allows to abort
703 another script handler by passing its callback ID.
704 - Fixed potential memory access bug and potential undefined behavior of
705 "init" event handlers.
706 - Print a time stamp along to each call of built-in function "message()".
707 - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
708 to retrieve all code blocks filtered out by the preprocessor.
709 - Added built-in script function "fork()".
710 - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
711 - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
712 - Fixed potential crash when accessing dynamic built-in array variables.
713 - Added built-in script function "callback_status()".
714 - Added built-in constant $CALLBACK_STATUS_TERMINATED.
715 - Added built-in constant $CALLBACK_STATUS_QUEUE.
716 - Added built-in constant $CALLBACK_STATUS_RUNNING.
717 - Removed max. value limitation of built-in functions "change_attack()",
718 "change_decay()" and "change_release()" to i.e. allow passing 2000000
719 for doubling the respective time.
720 - NKSP script editor syntax highlighting API: Fixed app termination due
721 to a lexer start condition stack underrun.
722 - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
723 USE_CODE_IF_NOT() preprocessor statements.
724 - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
725 can be set to disable all subsequent built-in "message()" function calls
726 on preprocessor level.
727 - Implemented built-in script function "change_sustain()".
728 - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
729 to avoid the editor app to crash on ill-formed text input.
730 - Added built-in script function "change_pan_time()".
731 - Added built-in script function "change_pan_curve()".
732 - Added built-in script function "change_cutoff_attack()".
733 - Added built-in script function "change_cutoff_decay()".

735 - Added built-in script function "change_cutoff_release()".
736 - Added built-in script function "change_cutoff_lfo_depth()".
737 - Added built-in script function "change_cutoff_lfo_freq()".
739 * Instruments DB:
740 - Fixed memory access bug of general DB access code which lead to
741 undefined behavior.
742 - Cleanup of instruments DB file creation and opening code.
743 - The instrument DB path of linuxsampler's --create-instruments-db argument
744 is now optional, if it is missing, then a default location is used.
745 - Added support for scanning SFZ (.sfz) files.
746 - Added support for scanning Sound Font (.sf2) files.
747 - Fixed undefined DB transaction behavior.
749 Version 2.0.0 (15 July 2015)
751 * packaging changes:
752 - fixed building with newer MinGW-w64
753 - Mac OS X: support the new dir for Core Audio SDK
754 - Mac OS X: fixed building outside source directory
755 - made sure all source files for hostplugins are included when
756 doing "make dist"
757 - removed empty directories left from the cvs to svn migration
758 - fixed compilation with gcc 4.6.1
759 - another "make dist" fix, for the LV2 plugin
760 - made --enable-pthread-testcancel default on Mac OS X
761 - minor Makefile fix for building lscpparser when build and source
762 directories are separate
763 - Mac OS X: made it possible to specify plugin installation dir to
764 configure
765 - Mac OS X: Makefile fix for the install-strip target
766 - fixed compilation with gcc 4.7
767 - fixed configure script error with old autoconf versions
768 - lsatomic.h: use gcc provided atomic functions if building with
769 gcc 4.7 and C++11
770 - modernized configure script
771 - fixed linkage error when building with
772 LDFLAGS="-Wl,--no-undefined" (#190)
773 - fixed compilation with Clang 3.2
774 - removed usage of deprecated Automake variable INCLUDES
775 - fixed building with C++11
776 - build fix: ChangeFlagRelaxed.h was missing in makefile
777 - build fix: libsndfile compiler flags were missing in some
778 makefiles
779 - fix for building with bison 3.0 (#202)
780 - Mac OS X: added temporary hack allowing to spawn gigedit as callback
781 on the process's main thread
782 - fixed build error on newer MinGW
783 - support building with older jack versions
784 - support building with spaces in vst sdk path
785 - enabled automake 'subdir-objects' option and moved external
786 source references (vst, au, asio) from makefiles to cpp files,
787 in order to get rid of warnings from automake 1.14
789 * general changes:
790 - Refactoring: moved the independent code from
791 the Gigasampler format engine to base classes
792 - command line option '--profile' is currently disabled, since the
793 respective profiling code is currently broken
794 - Introduced support for optional environment variable
795 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
796 where the sampler shall look for instrument editor plugins
797 (patch by Luis Garrido, slightly modified).
798 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
799 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
800 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
801 note (in this implementation of the sampler its simply hard routed to
802 the 1st effect send of the sampler channel, no matter what the actual
803 effect type is)
804 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
805 note (in this implementation of the sampler its simply hard routed to
806 the 2nd effect send of the sampler channel, no matter what the actual
807 effect type is)
808 - implemented support for internal LADSPA effects
809 - raised limit of program change queue from 100 to 512
810 (as suggested by Alex Stone)
811 - implemented sine LFO, pulse LFO and saw LFO
812 - experimental support for per voice equalization
813 - added command line option --exec-after-init
814 - Introduced new C++ API method:
815 EngineChannel::InstrumentFileName(int index)
816 allowing to retrieve the whole list of files used for the loaded
817 instrument on an engine channel (a.k.a. part). Some GigaStudio
818 instruments for example are splitted over several files like
819 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
820 - Added new C++ API method Sampler::GetGlobalMaxVoices().
821 - Added new C++ API method Sampler::GetGlobalMaxStreams().
822 - Added new C++ API method Sampler::SetGlobalMaxVoices().
823 - Added new C++ API method Sampler::SetGlobalMaxStreams().
824 - Various "const" and "restrict" optimizations.
825 - all engines: add pan CC value to instrument pan parameter before
826 applying panning, instead of using two separate pan functions in
827 series (#182)
828 - added a lock guard class for exception safe mutex handling and
829 used it everywhere appropriate
830 - Immediately apply scale tuning changes to active voices.
831 - Exposed scale tuning to C++ API (along to the already existing standard
832 SysEx way).
833 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
834 and broken for ppc64. (Seq_cst loads and stores are actually not
835 used in LS, so the bug wasn't noticable.)
836 - lsatomic.h: added ARMv7 support
837 - Added support for multiple MIDI input ports per sampler channel (and
838 added various new C++ methods for this new feature / design change, old
839 C++ API methods for managing SamplerChannel's MIDI inputs are now marked
840 as deprecated but are still there and should provide full behavior
841 backward compatibility).
842 - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
843 unsafe and caused compilation error with clang 2.x).
844 - Bugfix: only process the latest MIDI program change event.
845 - Introducing the LSCP shell, which provides convenient control of the
846 sampler from the command line by providing LSCP aware features.
847 - VirtualMidiDevice: Added support for program change.
848 - VirtualMidiDevice: Added support for bank select (MSB & LSB).
849 - VirtualMidiDevice: Added support for pitch bend.
850 - Aftertouch: extended API to explicitly handle channel pressure and
851 polyphonic key pressure events (so far polyphonic pressure was not
852 supported at all, and channel pressure was rerouted as CC128 but not
853 used so far).
854 - Added initial support for real-time instrument scripts. The script VM
855 code is shared by all sampler engine implemementations, however only the
856 gig file format currently provides support for storing instrument scripts
857 (as LinuxSampler extension to the original GigaStudio 4 format).
859 * Gigasampler format engine:
860 - implemented the "round robin keyboard" dimension
861 - fixed round robin and random dimensions for cases when number of
862 dimension zones is not a power of two
863 - made round robin use a counter for each region instead of each
864 key
865 - bugfix: pitch LFO controller "internal+aftertouch" was broken
866 - bugfix: filter keyboard tracking was broken
867 - filter performance fix (an unnecessary copy was made of the
868 filter parameters in each sub fragment)
869 - handle special case when pan parameter in gig file has max or
870 min value
871 - Exclusive Groups: don't ever stop voices of the same note,
872 doesn't sound naturally with a drumkit
873 - fixed EG1 modulation when attack or release is zero
874 - Fixed support for 'aftertouch' attenuation controller.
875 - Fixed crash that happened with velocity split sounds under certain
876 conditions (see also previous commit on libgig).
877 - fixed behaviour of filter LFO
879 * SFZ format engine:
880 - Initial implementation (not usable yet)
881 - added support for v2 multiple stage envelope generators
882 - added a fine-tuned v1 envelope generator instead of using the
883 one from the gig engine
884 - fixed memory leak and memory handling errors
885 - added support for trigger=first, trigger=legato and sw_previous
886 - allow non-numerical key values ("C#4" for example)
887 - "key" opcode now sets pitch_keycenter too
888 - fixed error when unloading instrument with same sample used by
889 multiple regions
890 - added some opcode aliases, like loopmode for loop_mode, to be
891 more compatible
892 - added support for trigger=release and rt_decay

1107 the driver will automatically connect to other CoreMIDI clients' ports
1108 (e.g. external MIDI devices being attached to the Mac)
1109 - added support for MIDI note on velocity filter
1110 - CoreMIDI: fixed memory deallocation error

1285 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1286 practically irrelevant, however it caused problems with the new LSCP
1287 shell's auto completion feature).

1302 - fix for building with bison 2.4 (#111)
1303 - fixed building with libgig installed in a non-standard directory
1304 - minor fix in configure for mmsystem.h detection on MinGW
1305 - Windows: look for editor plugins and Fantasia using base
1306 directory of liblinuxsampler dll (look in the same directory and one
1307 directory above)
1308 - configure script fix: removed unconditional use of SSE
1309 - fixed building with sqlite installed in a non-standard directory
1310 - when cross-compiling, don't try to create instruments.db
1311 - fix for new mingw-w64 version, which has usleep
1313 * general changes:
1314 - bugfix: on some POSIX systems instrument editor plugins refused to
1315 load as we used a non-portable Linux specific struct field
1316 (fixes bug #70, patch by Ronald Baljeu)
1317 - fixed endless loop which occured when loading an instrument editor
1318 plugin DLL on Windows systems failed
1319 - fixed memory leaks that occurred when liblinuxsampler was unloaded
1320 - optimized the SynchronizedConfig class so it doesn't wait
1321 unnecessarily long after an update
1322 - added support for notifying instrument editors on note-on / note-off
1323 events (e.g. to highlight the pressed keys on the virtual keyboard
1324 of gigedit)
1325 - added support for triggering notes by instrument editors (see above)
1326 - be verbose on DLL load errors (on Linux)
1327 - fixed di-harmonic triangle LFO implementation (this LFO implementation
1328 is only used by very few systems, most pick the int math
1329 implementation, which is usually faster)
1330 - fixes for audio drivers with varying buffer sizes
1331 - experimental support for running LinuxSampler as a DSSI, LV2 and
1332 VST plugin
1333 - notification events for stream/voice count statistics are now sent
1334 only when there are actual changes
1335 - added memory ordering constraints to improve stability on
1336 multi-core and multi-cpu systems
1337 - maximum voices and disk streams can now be altered at runtime
1338 - fixed CPU feature detection on x86_64 (maybe fixes #108)
1339 - automatic stacktrace mechanism is now turned off by default and can
1340 be switched on by command line option "--stacktrace" (the automatic
1341 stacktrace mechanism seems to be broken on most systems at the moment)
1342 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
1343 a pointer to the launched InstrumentEditor object
1344 - added optional 3rd party user data parameter for following
1345 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
1346 InstrumentEditor::Launch(),
1347 InstrumentManager::LaunchInstrumentEditor()
1348 - theoretical fix: made SynchronizedConfig follow C++0x memory
1349 model more strictly
1350 - fixes for using large audio device buffers
1351 - Windows: add the installation directory to the DLL search path
1352 when loading an editor plugin (solves problems with VST and
1353 gigedit on systems with other GTK versions installed)
1354 - updated linuxsampler man page
1356 * audio driver:
1357 - removed the nonsense audio channel constraint (which was hard coded to
1358 max. 100 audio channels) for most audio drivers
1359 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
1360 opposed to the LSCP specs
1361 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
1362 reflected the wrong value
1363 - fixed a memory management bug in ASIO driver
1364 - Makefile fix: JACK_CFLAGS wasn't used
1365 - JACK: use jack_client_open instead of the deprecated
1366 jack_client_new
1367 - added (experimental) CoreAudio driver
1368 - applied old fixes to the ASIO driver that were included in the
1369 previous binary release but accidentally never committed to CVS
1370 (fixes #117)
1371 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
1372 win64)
1373 - VST: added support for sample rate and buffer size changes
1374 - VST: close editor (Fantasia) when the VST is removed
1375 - VST: avoid opening Fantasia more than once for each VST instance
1376 - VST: export main function as "main" on Linux too (fix for
1377 energyXT)
1378 - VST: changed number of output channels from one stereo to 16
1379 stereo
1380 - added channel routing, fxsends and midi maps to the settings
1381 stored in the plugin state
1382 - performance optimization of AudioChannel::MixTo() and
1383 AudioChannel::CopyTo() methods using GCC vector exensions
1384 (if available)
1385 - ASIO fixes: avoid initializing the device twice, avoid throwing
1386 exception when getting parameters from a disconnected device
1388 * MIDI driver:
1389 - added JACK MIDI driver
1390 - dispatch bank select as ordinary CC as well, the user might seriously
1391 want to (mis)use it for some purpose ("fixed" in all current MIDI
1392 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
1393 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
1394 CoreMidi or AU
1395 - fixed mingw-w64 compilation error in MME driver
1396 - made program change handling in MIDI thread real-time safe by
1397 moving the logic to a non-RT thread
1398 - fixed minor memory leak in ALSA driver
1400 * instruments database:
1401 - avoid time consuming samples scanning when adding instruments
1402 to the instruments database
1403 - added support for handling lost files in the instruments database
1404 - Implemented option for adding instruments in separate directories
1405 in the instruments database
1406 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
1407 - work-around for missing fnmatch function on Windows to make
1408 instrument database compilable
1409 - added instrument database support on Windows
1410 works with both standalone mode and VST plugin.
1411 the instruments DB file is located in
1412 %USERPROFILE%\.linuxsampler\instruments.db which allows different
1413 databases for each windows user
1414 if no DB is present it automatically creates the .linuxsampler subdir
1415 and then creates an empty DB
1416 - fixed recursive import, which was broken on Windows
1418 * Gigasampler format engine:
1419 - fixed a memory leak that could happen when a channel was deleted
1420 while notes were playing
1421 - made it possible to load an instrument even if the audio thread
1422 isn't running
1423 - added partial support for the "Controller Triggered" MIDI rule,
1424 enough for piano gigs with pedal noise samples
1425 - minor fix: only mark FX sends as being modified if really the
1426 respective FX send MIDI controller was used
1427 - added support for GM global device volume SysEx message
1428 (can be selected at compile time to either apply globally to the
1429 whole sampler [default] or only to the sampler channels that are
1430 connected to the respective MIDI input port the SysEx message arrived
1431 on)
1432 - bugfix: notes triggered at position 0 in the audio buffer were
1433 sometimes wrongly killed in the same buffer, causing no sound to
1434 be played
1435 - added support for chromatic / drumkit mode Roland GS Sysex message
1436 which is usally used to switch a part between chromatic sounds and
1437 drumkit sounds (as opposed to their common default setting of MIDI
1438 part 10 being a drumkit part and all other ones chromatic parts), in
1439 LS however one can switch between the first 16 MIDI instrument maps
1440 defined for the sampler
1441 - made it possible to create multiple sample channels even if the
1442 audio thread isn't running
1443 - fixed crash when removing channel with active voices (#116)
1444 - bugfix: on sample reference changes (instrument editor), only
1445 un-cache the respective sample if it's really not used by any
1446 sampler engine anymore
1447 - re-cache samples in case they were changed by an instrument editor,
1448 e.g. when a sample was added while playing (#82)
1449 - fixed hanging notes which occured when note-off event had the exact
1450 same time stamp as the voice's note-on event and occured both in the
1451 same audio fragment cycle (fixes bug #112)
1452 - added support for the "fine tune" and "pitch bend range"
1453 instrument-level gig parameters
1454 - fixed minor artifacts in pitch bend handling
1455 - added support for GS Reset SysEx message
1456 - allow gig files to use unlimited downward pitch shifting
1457 - added a limit check for upward pitch shifting
1458 - bugfix: sometimes, when playing a note twice fast, the second
1459 note was silent
1460 - fixed crash happening when a pitch bend event arrived at the
1461 same time a new instrument was loading
1463 * LSCP server:
1464 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
1465 react on MIDI data arriving on certain sampler channels (so far only
1466 Note-On and Note-Off events are sent via this LSCP event)
1467 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1468 react on MIDI data arriving on certain MIDI input devices (so far only
1469 Note-On and Note-Off events are sent via this LSCP event)
1470 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
1472 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
1473 frontends to send MIDI messages to specific sampler channel
1474 - added two additional fields to GET FILE INSTRUMENT INFO command -
1476 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1477 was incorrect
1478 - Optimized the retrieval of the MIDI instrument mappings
1479 - added new LSCP command "SET VOICES" to globally alter the maximum
1480 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1481 be triggered respectively
1482 - added new LSCP command "SET STREAMS" to globally alter the maximum
1483 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1484 which will be triggered respectively
1485 - bugfix: retry if "select" returns EINTR (this fixes a crash when
1486 a gigedit file dialog is opened)
1487 - close all connections when LSCPServer is deleted
1488 - hard close of all sockets on exit
1489 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
1490 driver
1492 * Bug fixes:
1493 - fixed a crash which occurs when removing a sampler channel waiting
1494 to start instrument loading after another channel
1495 - fixed a crash which occurs when removing a sampler channel with
1496 instrument loading in progress (bug #113)
1497 - fixed termination caused by uncaught exception when adding MIDI
1498 instrument with PERSISTENT load mode
1499 - fixed possible iterator invalidations when resetting the sampler
1500 - fixed memory leaks when issuing the following LSCP commands:
1505 - fixed possible compilation error when sqlite is not present
1506 - fixed orphaned pointers when setting maximum voices limit (bug #118)
1507 - fixed crash when changing the audio output device of a sampler
1508 channel with loaded instrument and start playing notes
1509 - fixed endless loop in Engine::SuspendAll() (bug #120)
1510 - fixed a low-level atomic load function that was broken on 64-bit
1511 PowerPC, which probably could cause crashes on that platform
1512 - fixed a memory management error which could cause a crash when a
1513 plugin was unloaded
1514 - bugfix: two private structs had the same name, which could cause
1515 problems if the linker chose the wrong constructor
1516 - fixed low-level ConditionServer usage bug that caused lockups on
1517 Windows
1520 Version 0.5.1 (6 December 2007)
1522 * packaging changes:
1523 - added autoconf checks for pthread library
1524 - added autoconf check for pthread bug found on certain NPTL-enabled
1525 glibc versions (see Gentoo bug report #194076)
1526 - added autoconf checks for MS Windows
1528 * general changes:
1529 - bugfix: the thread used by an editor plugin didn't die when the
1530 editor closed
1531 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1532 out all the space. operator--() did not apply size_mask after
1533 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1534 order to avoid problems with the _NonVolatileReader functions.
1535 - bugfix: Stream.h: added a missing divide by BytesPerSample in
1536 GetWriteSpace(). Since this function is currently only used in
1537 the stream's qsort() compare function, it didn't trigger any
1538 bugs.
1539 - Resampler.h, Synthesizer.h: cubic interpolation now works in
1540 24bit mode too. Faster method to read 24bit words on little
1541 endian machines (x86): replaced 3 byte reads + shifts with a 1
1542 unaligned 32bit read and shift
1543 - experimental support for MS Windows (MIDI input via MME, AUDIO
1544 output via ASIO)
1545 - made handling of SIGINT signal (Ctrl-C) a bit more robust
1546 - support for monitoring the total number of active disk streams
1547 (new LSCP commands: GET TOTAL_STREAM_COUNT,
1550 * AUDIO driver:
1551 - added Windows ASIO low latency audio driver
1553 * MIDI driver:
1554 - added MME Windows MIDI driver
1556 * LSCP server:
1557 - added support for Windows style path / filenames, however with
1558 forward slash path separators instead of backslash
1559 (i.e. "C:/foo/bar.gig")
1560 - allow naughty liblscp to send non-string device parameters within
1561 apostrophes as well
1562 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1563 "LIST FILE INSTRUMENTS <file>" and
1564 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1565 about an arbitrary instrument file on the system where the sampler is
1566 running on
1568 Version 0.5.0 (15 October 2007)
1570 * packaging changes:
1571 - config.h is not going to be installed along with liblinuxsampler's
1572 API header files anymore
1573 - only the API relevant header (and source) files will be exported to
1574 the Doxygen API documentation (explicitly listed in Doxyfile.in)
1575 - added completely new XCode project files for Mac OSX which is now
1576 capable to execute our autoconf environment, thus no need anymore
1577 to maintain the compile time configuration file (osx/version.h) for
1578 OSX manually (patch by Toshi Nagata)
1579 - fixed buggy boolean --enable-foo / --disable-foo configure script
1580 parameters
1581 - global.h now only covers global definitions that are needed for the
1582 C++ API header files, all implementation internal global definitions
1583 are now in global_private.h
1584 - atomic.h is not exposed to the C++ API anymore
1585 - no need to include config.h anymore for using LS's API header files
1586 - fixed warnings in API doc generation
1588 * general changes:
1589 - replaced the old, confusing MIDI program change mechanism by a
1590 flexible MIDI instrument mapper which allows to map arbitrary
1591 (MIDI bank, MIDI program) pairs with arbitrary
1592 (engine type, instrument file, file index) triplets which will be
1593 loaded on the respective channel when such MIDI program change
1594 messages arrive, beside that, each entry allows to define a life-time
1595 strategy for the instrument, so the user can define whether the
1596 instrument should i.e. be permanently loaded (to be able to switch
1597 quickly among sounds) or i.e. loaded just on demand when the
1598 respective program change arrives (to safe RAM space), as well as a
1599 global volume factor for each entry, so the user can adjust the volume
1600 dynamic of his mapped instrument collection without having to modify
1601 the instrument files, also one can manage arbitrary amount of such
1602 MIDI instrument maps and assign each sampler channel individually
1603 a certain map, so that i.e. separation of normal instruments and
1604 drumkits is possible
1605 - new notification events for tracking changes to audio/MIDI devices,
1606 MIDI instrument maps, MIDI instruments, FX sends, global volume.
1607 - sampler was limited to load max. 200 instruments in the background
1608 due to a constant size RingBuffer FIFO which is now replaced by a
1609 dynamic (unlimited) size std::list FIFO
1610 - added FX sends, these allow to route audio signals to arbitrary audio
1611 output channels for being processed by external effect processors
1612 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1613 controllers
1614 - global (sampler wide) volume can now be controlled at runtime
1615 - Implemented new, improved notification system
1616 - fixed compilation errors regarding OSX
1617 (patch by Toshi Nagata)
1618 - implemented instruments database
1619 - added support for escape sequences to the instruments database
1620 - added highly experimental support for on-the-fly instrument editing
1621 within the sampler's process (by using instrument editor plugins),
1622 you'll notice the new "Registered instrument editors:" message on
1623 startup, added a new LSCP command:
1624 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1625 to spawn a matching instrument editor for the instrument on the
1626 given sampler channel, the plugin path can be overridden at compile
1627 time with ./configure --enable-plugin-dir=/some/dir
1628 - added experimental code for synchronizing instrument editors hosted
1629 in the sampler's process to safely edit instruments while playing
1630 without a crash (hopefully) by either suspending single regions
1631 wherever possible or if unavoidable whole engine(s)
1632 - fixed several issues in fundamental "Thread" class: set scheduling
1633 policy and priority on thread level, set a minimum stack size for
1634 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1635 threads simply inherited properties of starting thread instead of
1636 setting their own policy and priority
1637 - minor fix in our automatic stack trace mechanism on crashes, the
1638 main process did not wait for the stack trace process to finish
1639 its output
1640 - fixed some minor memory leaks
1641 - reenabled assembly features support, at the moment only for
1642 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1643 - minor assembly fix in x86 features detection (don't use the PIC
1644 register, to avoid relocations in the text segment at runtime)
1645 - POSIX callback functions of Thread.h are hidden
1647 * MIDI driver:
1648 - dispatch bank select (MSB and LSB) messages
1650 * audio driver:
1651 - the ALSA audio output driver parameters now reflect the correct
1652 parameter value ranges for the respective selected sound card
1653 (patch by Till Wimmer, a bit fixed and extended)
1655 * Gigasampler format engine:
1656 - if a filter is used and EG2 finishes before EG1, let the voice
1657 die when EG2 has finished (this fixes a problem with clicks and
1658 voice starvation for some gigs)
1659 - playback is no longer disabled during instrument loading
1660 - all notes playing on a channel that changes its instrument keep
1661 playing with the old instrument until they get a note off
1662 command
1663 - EG fix: a release value of zero could cause noises or crash
1664 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1665 - EG fine tuning: when attack is zero the EG starts at a level
1666 above max sustain level, which means that there is a decay phase
1667 even if sustain is 100%
1668 - more EG fixes: the level could sometimes go below zero and cause
1669 noises or crashes
1670 - minor fix of EGDecay (patch by Toshi Nagata)
1671 - fixed compiler error when --enable-override-filter-type was
1672 supplied to the configure script (fixes #46)
1673 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1674 instead of a fix value
1675 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1676 127 (solo mode) only kill voices if the respective mode really
1677 changed
1679 * LSCP server:
1680 - fixed compile time error for old Bison versions
1681 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1682 - parser now supports extended ASCII character set
1683 (up to ASCII code 255, i.e. includes now umlauts and accents)
1684 - filename arguments in LSCP commands now allow to use escape
1685 sequences, that is directly literal as one of: \', \", \\, \n, \r,
1686 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1687 code value like \xf2) (fixes bug #24)
1688 - the following LSCP commands now also support escape sequences for at
1689 least one of their text-based parameters (i.e. name, description):
1696 - returns verbose syntax errors (line and column where syntax error
1697 occured, the unexpected character and the actually expected, possible
1698 character(s), the latter only if less than 5 possibilities)
1699 - made sure that LSCP syntax is not affected by gigedit locale
1700 settings
1701 - bugfix regarding strings parameter lists: all comma separated lists
1702 of strings were treated as being one string containing commas
1703 (fixes #57)
1705 * Bug fixes:
1706 - fixed crash occurring on certain LSCP scripts (Bug 39)
1707 - another thread safety fix for lscp "load engine" and "set
1708 channel audio output device"
1709 - fixed a crash which occurs when reassigning the same engine
1710 on a sampler channel with connected MIDI device
1711 - fixed a crash which occurs when changing the number of ports of a MIDI
1712 device connected to a sampler channel to number less then or equal
1713 to the index of the port to which the sampler channel is connected.
1714 - The previous bindings were not been disconnected when altering
1715 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1716 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1717 - The active stream/voice count statistic was incorrect.
1718 - notification events were not been sent for some sampler
1719 channel changes
1720 - added default min and max values to restrict the number of allowed
1721 audio output channels and MIDI input ports
1722 - the connection to the PCM interface is now closed when destroying
1723 an audio output device
1724 - files with slash in their path or filename could not be loaded
1726 * test cases:
1727 - updated and fixed (haven't been touched in a while)
1729 Version 0.4.0 (24 November 2006)
1731 * packaging changes:
1732 - changed deprecated copyright attribute to license; added ldconfig
1733 to post-(un)install steps; added devel package for liblinuxsampler;
1734 to linuxsampler.spec (RPM)
1735 - install necessary development header files for allowing 3rd party
1736 applications to link against liblinuxsampler
1737 - liblinuxsampler's API documentation can be generated with 'make docs'
1738 (Doxygen required)
1739 - added benchmark to automatically detect the best triangle LFO
1740 implementation (currently either an integer math solution or a
1741 di-harmonic approximation), automatic detection can be overriden
1742 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1743 configure script argument though (mandatory for cross-compilation)
1744 - do not automatically pick optimized gcc flags if the user already
1745 provided some on his own (as CXXFLAGS)
1746 - added compile time option to disable processing of All-Notes-Off MIDI
1747 messages
1748 - added compile time options to allow disabling the various audio and
1749 MIDI drivers
1750 - fixed automatic GCC CPU switch detection on PPC
1751 (patch by Ebrahim Mayat)
1753 * Gigasampler format engine:
1754 - extensive synthesis optimization
1755 (reimplementation of EGs and LFO(s), removed synthesis parameter
1756 prerendering and the synthesis parameter matrix in general, splitting
1757 each audio fragment into subfragments now where each subfragment uses
1758 constant pitch and filter coefficients. The volume coefficient is
1759 linearly interpolated inside a subfragment, unless
1760 --disable-interpolate-volume is set.)
1761 - fine tuning of the EG modulation parameters
1762 - improved filter cutoff calculation by adding support for the
1763 following gig parameters: Cutoff freq (used when no cutoff
1764 controller is defined), Control invert, Minimum cutoff, Velocity
1765 curve and Velocity range. The keyboard tracking now scales
1766 cutoff frequency instead of resonance.
1767 - added support for gig parameter Resonance.
1768 - fixed bug in sysex handling (patch by Juan Linietsky)
1769 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1770 which can be overridden with --enable-global-attenuation
1771 - EG fixes: made the length of "attack hold" stage more
1772 accurate. Release stage can now start before attack stage
1773 ends. Cancel release didn't work when sustain was zero. Attack
1774 time now has a minimal value to prevent clicks.
1775 - fixed pitch changes larger than one octave
1776 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1777 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1778 all modes can be altered via standard GM messages, that is CC5 for
1779 altering portamento time, CC65 for enabling / disabling portamento
1780 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1781 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1782 parameter) and crossfade
1783 - added support for the "attenuation controller threshold" gig
1784 parameter
1785 - added smoothing of volume changes caused by control change
1786 messages
1787 - sample loop parameters are now taken from the DimensionRegion
1788 instead of the wave chunk
1789 - fixed keyswitching for v3 gigs with a number of keyswitch splits
1790 not equal to a power of two
1791 - reimplementation of the filter algorithm. The new filter is more
1792 accurate and supports all gig filter types, including bandreject
1793 and lowpass turbo.
1794 - real support for 24 bit samples - samples are not truncated to
1795 16 bits anymore
1796 - support for aftertouch (channel pressure, not polyphonic
1797 aftertouch)
1798 - LFO1 behaviour fixed (dampening from max volume instead of
1799 amplifying from 0)
1801 * LSCP server:
1802 - fixed application exit on broken pipe error (fixes bug #20)
1803 - fixed the notification messages delay due to lack of
1804 network activity (fixes bug #26)
1805 - fixed parser bug which occured on space(s) within device parameters
1808 * audio driver:
1809 - added aRts audio output driver (by no means RT safe)
1811 * MIDI driver:
1812 - fixed legacy sysex code which caused dispatching of MIDI SysEx
1813 messages several times instead of once
1814 - API extension for MIDI drivers which already supply exact time stamps
1815 for events (i.e. for offline rendering based MIDI drivers)
1816 - added checks for bad MIDI data
1818 * linuxsampler application:
1819 - show available sampler engine types on startup
1821 * general changes:
1822 - support for muting sampler channels and solo mode of the same, two new
1823 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1824 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1825 introduced for this, the behavior is the same like on a mixer console
1826 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1827 --enable-process-muted-channels which can be used to enable the
1828 processing of muted channels.
1829 - support for sostenuto pedal
1830 - support for monitoring the total number of active voices
1833 - fixed some memory management errors
1834 - fixed some concurrency problems that could lead to crashes when
1835 LSCP commands were executed
1836 - fixed crash when instrument loading failed previously on the same
1837 sampler channel (fixes bug #36)
1839 Version 0.3.3 (15 July 2005)
1841 * packaging changes:
1842 - fixed compilation with gcc 4.0
1844 * Gigasampler format engine:
1845 - LFO preprocessing was performed even though the respective LFO was
1846 disabled by the instrument patch (minor efficiency fix)
1847 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1848 for volume ramp downs in the same fragment (needed for current voice
1849 stealing implementation) then simply inform the user with a warning
1850 about possible click sounds and reduce the volume ramp down
1851 appropriately instead of cancelling the audio device connection
1853 Version 0.3.2 (24 June 2005)
1855 * packaging changes:
1856 - updated autotools build files to compile on OS X
1857 (conditional compilation of CoreMIDI and MidiShare drivers)
1858 - hand-crafted assembly optimization code can be disabled with
1859 './configure --disable-asm' (definitely not recommended)
1860 - fixed 'make dist' rule to include all necessary files
1861 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1862 (due to 'dist-bzip2' automake option)
1864 * Gigasampler format engine:
1865 - support for the gig parameters for "release velocity response" curves
1866 - fine tuning of the EGADSR envelope
1867 - volume of release triggered samples now depends on note-on velocity,
1868 note length and gig parameter "release trigger decay" instead of
1869 note-off velocity.
1870 - revised voice stealing
1871 (fixes crash and endless loop caused by voice stealing)
1872 - don't reset scale tuning on instrument or audio output device change
1873 - handle key group conflicts right at the beginning of each fragment
1874 instead of when the respective voice is actually launched
1875 (fixes undefined behavior if stolen voices belonged to a key group -
1876 this case was followed by a "killed voice survived" error message)
1877 - fixed minor issue with null/silence samples
1878 (those stole voices even though they don't need a voice at all which
1879 resulted in "voice stealing didn't work out" messages)
1880 - don't reset volume, pan, pitch and MIDI controller values on
1881 instrument or audio output device change
1883 * LSCP server:
1884 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1885 - fixed LSCP event "CHANNEL_INFO" notification
1886 (e.g. did not notify on volume changes or MIDI program change events)
1888 * linuxsampler application:
1889 - added command line parameters --lscp-addr and --lscp-port to override
1890 default IP address and port of LSCP server
1892 Version 0.3.1 (24 May 2005)
1894 * initial release
