* Fixed crash on certain MIDI RPN and NRPN messages that occurred if no
  real-time instrument script was loaded.

* Bumped version (2.1.1.svn71).

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

553 - Implemented built-in script function "change_attack()".
554 - Implemented built-in script function "change_decay()".
555 - Implemented built-in script function "change_release()".
556 - Fixed all change_*() built-in script functions to apply their
557 synthesis parameter changes immediately in case the respective note
558 was triggered at the same time, instead of scheduling the parameter
559 change, especially because it would cause some parameter types's
560 changes either to be ramped (i.e. change_vol()) or other types even
561 to have not effect at all (i.e. change_attack()).
562 - Implemented built-in script function "sh_left()".
563 - Implemented built-in script function "sh_right()".
564 - Implemented built-in script function "min()".
565 - Implemented built-in script function "max()".
566 - NKSP Fix: "init" event handler was not always executed when a script
567 was loaded.
568 - NKSP built-in wait() script function: abort script execution if
569 a negative or zero wait time was passed as argument (since this is
570 a common indication of a bug either of the script or even of the
571 engine, which could lead to RT instability or even worse).
572 - ScriptVM: Implemented automatic suspension of RT safety
573 threatening scripts.
574 - Provide more user friendly error messages on syntax errors.
575 - Fixed NKSP parser warning "Not a statement" when assigning an
576 initializer list to an array variable.

579 - Implemented built-in script function "change_amp_lfo_depth()".
580 - Implemented built-in script function "change_amp_lfo_freq()".
581 - Implemented built-in script function "change_pitch_lfo_depth()".
582 - Implemented built-in script function "change_pitch_lfo_freq()".
583 - Implemented built-in script function "change_vol_time()".
584 - Implemented built-in script function "change_tune_time()".
585 - Implemented built-in script function "fade_in()".
586 - Implemented built-in script function "fade_out()".
587 - Fixed acceptance of wrong data type of parameters passed to built-in
588 script functions "change_vol()", "change_tune()", "change_pan()",
589 "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
590 "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
591 "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
592 - Added built-in script function "get_event_par()" and implemented some
593 of its possible parameter selections.
594 - Added built-in script function "set_event_par()" and implemented some
595 of its possible parameter selections.
596 - Fixed a bunch of scheduler time related bugs.
597 - Fixed polyphonic variables not being reset to zero after usage.
598 - Built-in "ignore_event()" function: argument is now optional, like with
599 built-in function "ignore_controller()".
600 - Implemented built-in script function "change_velo()".
601 - Implemented built-in script function "change_note()".
602 - Adjusted behavior of "change_vol()" and "change_tune()" to a more
603 intuitive behavior if used in combination with "change_vol_time()" or
604 "change_tune_time()" respectively: now tuning/volume changes are only
605 assigned (without delay) immediately to a new note if the respective
606 timing function has not been called before, otherwise the volume/tuning
607 changes are automatically faded (before, only the event's time stamp was
608 relevant).
609 - Implemented built-in script function "array_equal()".
610 - Implemented built-in script function "search()".
611 - Implemented built-in script function "sort()".
612 - NKSP Fix: Never suspend "init" event handlers.
613 - Implemented built-in script function "same_region()" (currently only
614 available for gig format engine).
615 - Added built-in script constant "$NKSP_LINEAR".
616 - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
617 - Implemented built-in script function "change_vol_curve()".
618 - Implemented built-in script function "change_tune_curve()".
619 - built-in "play_note()" function now supports a sample playback start
620 offset with argument 3, where special value -1 means to use the regular
621 sample offset as defined by the instrument file.
622 - Built-in array variable %KEY_DOWN[] is now a read-only variable.
623 - Built-in variable $EVENT_NOTE is now a read-only variable.
624 - Built-in variable $EVENT_VELOCITY is now a read-only variable.
625 - built-in "play_note()" function now accepts -2 for its fourth argument
626 (note duration) which means the life time of the note shall be sticked
627 to the requested note number of argument 1.
628 - Fix: built-in "play_note()" function now returns 0 as result value if
629 -1 was passed for its fourth argument (note duration) and the respective
630 parent note is already gone.
631 - Implemented built-in script function "change_play_pos()".
632 - NKSP language: Added support for user declared const array variables.
633 - NKSP language: Raise parser warning if array variable is accessed with
634 an index that exceeds the array's size.
635 - NKSP language fix: Unknown characters were not handled correctly.
636 - NKSP language: Added support for "synchronized .. end synchronized"
637 code blocks.
638 - Implemented built-in script function "abort()" which allows to abort
639 another script handler by passing its callback ID.
640 - Fixed potential memory access bug and potential undefined behavior of
641 "init" event handlers.
642 - Print a time stamp along to each call of built-in function "message()".
643 - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
644 to retrieve all code blocks filtered out by the preprocessor.
645 - Added built-in script function "fork()".
646 - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
647 - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
648 - Fixed potential crash when accessing dynamic built-in array variables.
649 - Added built-in script function "callback_status()".
650 - Added built-in constant $CALLBACK_STATUS_TERMINATED.
651 - Added built-in constant $CALLBACK_STATUS_QUEUE.
652 - Added built-in constant $CALLBACK_STATUS_RUNNING.
653 - Removed max. value limitation of built-in functions "change_attack()",
654 "change_decay()" and "change_release()" to i.e. allow passing 2000000
655 for doubling the respective time.
656 - NKSP script editor syntax highlighting API: Fixed app termination due
657 to a lexer start condition stack underrun.
658 - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
659 USE_CODE_IF_NOT() preprocessor statements.
660 - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
661 can be set to disable all subsequent built-in "message()" function calls
662 on preprocessor level.
663 - Implemented built-in script function "change_sustain()".
664 - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
665 to avoid the editor app to crash on ill-formed text input.

673 - Added built-in script function "change_cutoff_lfo_freq()".
674
675 * Instruments DB:
676 - Fixed memory access bug of general DB access code which lead to
677 undefined behavior.
678 - Cleanup of instruments DB file creation and opening code.
679 - The instrument DB path of linuxsampler's --create-instruments-db argument
680 is now optional, if it is missing, then a default location is used.
681 - Added support for scanning SFZ (.sfz) files.
682 - Added support for scanning Sound Font (.sf2) files.
683 - Fixed undefined DB transaction behavior.
684
685 Version 2.0.0 (15 July 2015)

688 - fixed building with newer MinGW-w64
689 - Mac OS X: support the new dir for Core Audio SDK
690 - Mac OS X: fixed building outside source directory
691 - made sure all source files for hostplugins are included when
692 doing "make dist"
693 - removed empty directories left from the cvs to svn migration
694 - fixed compilation with gcc 4.6.1
695 - another "make dist" fix, for the LV2 plugin
696 - made --enable-pthread-testcancel default on Mac OS X
697 - minor Makefile fix for building lscpparser when build and source
698 directories are separate
699 - Mac OS X: made it possible to specify plugin installation dir to
700 configure
701 - Mac OS X: Makefile fix for the install-strip target
702 - fixed compilation with gcc 4.7
703 - fixed configure script error with old autoconf versions
704 - lsatomic.h: use gcc provided atomic functions if building with
705 gcc 4.7 and C++11
706 - modernized configure script
707 - fixed linkage error when building with
708 LDFLAGS="-Wl,--no-undefined" (#190)
709 - fixed compilation with Clang 3.2
710 - removed usage of deprecated Automake variable INCLUDES
711 - fixed building with C++11
712 - build fix: ChangeFlagRelaxed.h was missing in makefile
713 - build fix: libsndfile compiler flags were missing in some
714 makefiles
715 - fix for building with bison 3.0 (#202)
716 - Mac OS X: added temporary hack allowing to spawn gigedit as callback
717 on the process's main thread
718 - fixed build error on newer MinGW
719 - support building with older jack versions
720 - support building with spaces in vst sdk path
721 - enabled automake 'subdir-objects' option and moved external
722 source references (vst, au, asio) from makefiles to cpp files,
723 in order to get rid of warnings from automake 1.14
724
725 * general changes:
726 - Refactoring: moved the independent code from
727 the Gigasampler format engine to base classes
728 - command line option '--profile' is currently disabled, since the
729 respective profiling code is currently broken
730 - Introduced support for optional environment variable
731 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
732 where the sampler shall look for instrument editor plugins
733 (patch by Luis Garrido, slightly modified).
734 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
735 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
736 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
737 note (in this implementation of the sampler its simply hard routed to
738 the 1st effect send of the sampler channel, no matter what the actual
739 effect type is)
740 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
741 note (in this implementation of the sampler its simply hard routed to
742 the 2nd effect send of the sampler channel, no matter what the actual
743 effect type is)
744 - implemented support for internal LADSPA effects
745 - raised limit of program change queue from 100 to 512
746 (as suggested by Alex Stone)
747 - implemented sine LFO, pulse LFO and saw LFO
748 - experimental support for per voice equalization
749 - added command line option --exec-after-init
750 - Introduced new C++ API method:
751 EngineChannel::InstrumentFileName(int index)
752 allowing to retrieve the whole list of files used for the loaded
753 instrument on an engine channel (a.k.a. part). Some GigaStudio
754 instruments for example are splitted over several files like
755 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
756 - Added new C++ API method Sampler::GetGlobalMaxVoices().
757 - Added new C++ API method Sampler::GetGlobalMaxStreams().
758 - Added new C++ API method Sampler::SetGlobalMaxVoices().
759 - Added new C++ API method Sampler::SetGlobalMaxStreams().
760 - Various "const" and "restrict" optimizations.
761 - all engines: add pan CC value to instrument pan parameter before
762 applying panning, instead of using two separate pan functions in
763 series (#182)
764 - added a lock guard class for exception safe mutex handling and
765 used it everywhere appropriate
766 - Immediately apply scale tuning changes to active voices.
767 - Exposed scale tuning to C++ API (along to the already existing standard
768 SysEx way).
769 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
770 and broken for ppc64. (Seq_cst loads and stores are actually not
771 used in LS, so the bug wasn't noticable.)
772 - lsatomic.h: added ARMv7 support
773 - Added support for multiple MIDI input ports per sampler channel (and
774 added various new C++ methods for this new feature / design change, old
775 C++ API methods for managing SamplerChannel's MIDI inputs are now marked
776 as deprecated but are still there and should provide full behavior
777 backward compatibility).
778 - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
779 unsafe and caused compilation error with clang 2.x).
780 - Bugfix: only process the latest MIDI program change event.
781 - Introducing the LSCP shell, which provides convenient control of the
782 sampler from the command line by providing LSCP aware features.
783 - VirtualMidiDevice: Added support for program change.
784 - VirtualMidiDevice: Added support for bank select (MSB & LSB).
785 - VirtualMidiDevice: Added support for pitch bend.
786 - Aftertouch: extended API to explicitly handle channel pressure and
787 polyphonic key pressure events (so far polyphonic pressure was not
788 supported at all, and channel pressure was rerouted as CC128 but not
789 used so far).
790 - Added initial support for real-time instrument scripts. The script VM
791 code is shared by all sampler engine implemementations, however only the
792 gig file format currently provides support for storing instrument scripts
793 (as LinuxSampler extension to the original GigaStudio 4 format).
794
795 * Gigasampler format engine:
796 - implemented the "round robin keyboard" dimension
797 - fixed round robin and random dimensions for cases when number of
798 dimension zones is not a power of two
799 - made round robin use a counter for each region instead of each
800 key
801 - bugfix: pitch LFO controller "internal+aftertouch" was broken
802 - bugfix: filter keyboard tracking was broken
803 - filter performance fix (an unnecessary copy was made of the
804 filter parameters in each sub fragment)
805 - handle special case when pan parameter in gig file has max or
806 min value
807 - Exclusive Groups: don't ever stop voices of the same note,
808 doesn't sound naturally with a drumkit
809 - fixed EG1 modulation when attack or release is zero
810 - Fixed support for 'aftertouch' attenuation controller.
811 - Fixed crash that happened with velocity split sounds under certain
812 conditions (see also previous commit on libgig).
813 - fixed behaviour of filter LFO
814
815 * SFZ format engine:
816 - Initial implementation (not usable yet)
817 - added support for v2 multiple stage envelope generators
818 - added a fine-tuned v1 envelope generator instead of using the
819 one from the gig engine
820 - fixed memory leak and memory handling errors
821 - added support for trigger=first, trigger=legato and sw_previous
822 - allow non-numerical key values ("C#4" for example)
823 - "key" opcode now sets pitch_keycenter too
824 - fixed error when unloading instrument with same sample used by
825 multiple regions
826 - added some opcode aliases, like loopmode for loop_mode, to be
827 more compatible
828 - added support for trigger=release and rt_decay
829 - added support for off_mode=normal
830 - added support for random, seq_position, seq_length and volume
831 - added v1 LFO opcodes to parser (no support in engine yet)
832 - added support for amp_veltrack and amp_velcurve_N
833 - fine-tuned the default velocity curve
834 - added support for transpose
835 - fixed crash when using sw_down/up
836 - improved logic for sw_lokey/hikey/up/down/last
837 - added more v1 aliases to parser
838 - reduced memory usage for sfz data
839 - RT-safeness: avoid malloc in audio thread
840 - fixed a bug that could cause voice stealing to fail
841 - optimized sample lookup
842 - improved support for exclusive groups (group, off_by and
843 off_mode)
844 - added support for controller triggered regions (on_locc/on_hicc)
845 - added support for loop_mode=one_shot
846 - fixed playback of 16 bit wav files on big endian CPUs
847 - added support for Ogg Vorbis sample files
848 - use loop markers from sample file if loop_start and loop_end are
849 not set in sfz file
850 - implemeted filters. Filter types: lowpass, bandpass, bandreject
851 and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,
852 cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
853 cutoff_cc, cutoff_chanaft.
854 - bugfix: zero ampeg_sustain didn't work
855 - added support for velocity effect on amplifier envelope time
856 (ampeg_vel2attack, ampeg_vel2decay, ampeg_vel2sustain and
857 ampeg_vel2release)
858 - added support for EG hold (ampeg_hold)
859 - added support for sample offset (offset)
860 - use the newly introduced signal units model

866 pitcheg_vel2attack, pitcheg_vel2hold, pitcheg_vel2decay,
867 pitcheg_vel2sustain, pitcheg_vel2release, pitcheg_depth
868 - implemented opcodes pitchlfo_delay, pitchlfo_freq,
869 pitchlfo_depth, fillfo_delay, fillfo_freq, fillfo_depth,

1043 the driver will automatically connect to other CoreMIDI clients' ports
1044 (e.g. external MIDI devices being attached to the Mac)
1045 - added support for MIDI note on velocity filter
1046 - CoreMIDI: fixed memory deallocation error
1047 - Fixed variable underflow in VirtualMidiDevice, which caused graphical

1217 crashes and noise on such transitions).
1218 - ignore missing LADSPA paths without ignoring valid LADSPA paths
1219 (fixes #208)
1220 - Fixed bug in LSCP grammar definition which caused a statement like
1221 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1222 practically irrelevant, however it caused problems with the new LSCP
1223 shell's auto completion feature).
1224 - Fixed MIDI program change messages being ignored if quickly executed
1225 after each other (fixes #231).
1226

1242 directory of liblinuxsampler dll (look in the same directory and one
1243 directory above)
1244 - configure script fix: removed unconditional use of SSE
1245 - fixed building with sqlite installed in a non-standard directory
1246 - when cross-compiling, don't try to create instruments.db
1247 - fix for new mingw-w64 version, which has usleep
1248
1249 * general changes:

1252 (fixes bug #70, patch by Ronald Baljeu)
1253 - fixed endless loop which occured when loading an instrument editor
1254 plugin DLL on Windows systems failed
1255 - fixed memory leaks that occurred when liblinuxsampler was unloaded

1259 events (e.g. to highlight the pressed keys on the virtual keyboard
1260 of gigedit)
1261 - added support for triggering notes by instrument editors (see above)
1262 - be verbose on DLL load errors (on Linux)
1263 - fixed di-harmonic triangle LFO implementation (this LFO implementation
1264 is only used by very few systems, most pick the int math
1265 implementation, which is usually faster)
1266 - fixes for audio drivers with varying buffer sizes
1267 - experimental support for running LinuxSampler as a DSSI, LV2 and
1268 VST plugin
1269 - notification events for stream/voice count statistics are now sent
1270 only when there are actual changes
1271 - added memory ordering constraints to improve stability on
1272 multi-core and multi-cpu systems
1273 - maximum voices and disk streams can now be altered at runtime
1274 - fixed CPU feature detection on x86_64 (maybe fixes #108)
1275 - automatic stacktrace mechanism is now turned off by default and can
1276 be switched on by command line option "--stacktrace" (the automatic
1277 stacktrace mechanism seems to be broken on most systems at the moment)
1278 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
1279 a pointer to the launched InstrumentEditor object
1280 - added optional 3rd party user data parameter for following
1281 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
1282 InstrumentEditor::Launch(),
1283 InstrumentManager::LaunchInstrumentEditor()
1284 - theoretical fix: made SynchronizedConfig follow C++0x memory
1285 model more strictly
1286 - fixes for using large audio device buffers
1287 - Windows: add the installation directory to the DLL search path
1288 when loading an editor plugin (solves problems with VST and
1289 gigedit on systems with other GTK versions installed)
1290 - updated linuxsampler man page
1291
1292 * audio driver:
1293 - removed the nonsense audio channel constraint (which was hard coded to
1294 max. 100 audio channels) for most audio drivers
1295 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
1296 opposed to the LSCP specs
1297 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
1298 reflected the wrong value
1299 - fixed a memory management bug in ASIO driver
1300 - Makefile fix: JACK_CFLAGS wasn't used
1301 - JACK: use jack_client_open instead of the deprecated
1302 jack_client_new
1303 - added (experimental) CoreAudio driver
1304 - applied old fixes to the ASIO driver that were included in the
1305 previous binary release but accidentally never committed to CVS
1306 (fixes #117)
1307 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
1308 win64)
1309 - VST: added support for sample rate and buffer size changes
1310 - VST: close editor (Fantasia) when the VST is removed
1311 - VST: avoid opening Fantasia more than once for each VST instance
1312 - VST: export main function as "main" on Linux too (fix for
1313 energyXT)
1314 - VST: changed number of output channels from one stereo to 16
1315 stereo
1316 - added channel routing, fxsends and midi maps to the settings
1317 stored in the plugin state
1318 - performance optimization of AudioChannel::MixTo() and
1319 AudioChannel::CopyTo() methods using GCC vector exensions
1320 (if available)
1321 - ASIO fixes: avoid initializing the device twice, avoid throwing
1322 exception when getting parameters from a disconnected device
1323
1324 * MIDI driver:
1325 - added JACK MIDI driver
1326 - dispatch bank select as ordinary CC as well, the user might seriously
1327 want to (mis)use it for some purpose ("fixed" in all current MIDI
1328 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
1329 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
1330 CoreMidi or AU
1331 - fixed mingw-w64 compilation error in MME driver
1332 - made program change handling in MIDI thread real-time safe by
1333 moving the logic to a non-RT thread
1334 - fixed minor memory leak in ALSA driver
1335
1336 * instruments database:
1337 - avoid time consuming samples scanning when adding instruments
1338 to the instruments database
1339 - added support for handling lost files in the instruments database
1340 - Implemented option for adding instruments in separate directories
1341 in the instruments database
1342 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
1343 - work-around for missing fnmatch function on Windows to make
1344 instrument database compilable
1345 - added instrument database support on Windows
1346 works with both standalone mode and VST plugin.
1347 the instruments DB file is located in
1348 %USERPROFILE%\.linuxsampler\instruments.db which allows different
1349 databases for each windows user
1350 if no DB is present it automatically creates the .linuxsampler subdir
1351 and then creates an empty DB
1352 - fixed recursive import, which was broken on Windows
1353
1354 * Gigasampler format engine:
1355 - fixed a memory leak that could happen when a channel was deleted
1356 while notes were playing
1357 - made it possible to load an instrument even if the audio thread
1358 isn't running
1359 - added partial support for the "Controller Triggered" MIDI rule,
1360 enough for piano gigs with pedal noise samples
1361 - minor fix: only mark FX sends as being modified if really the
1362 respective FX send MIDI controller was used
1363 - added support for GM global device volume SysEx message
1364 (can be selected at compile time to either apply globally to the
1365 whole sampler [default] or only to the sampler channels that are
1366 connected to the respective MIDI input port the SysEx message arrived
1367 on)
1368 - bugfix: notes triggered at position 0 in the audio buffer were
1369 sometimes wrongly killed in the same buffer, causing no sound to
1370 be played
1371 - added support for chromatic / drumkit mode Roland GS Sysex message
1372 which is usally used to switch a part between chromatic sounds and
1373 drumkit sounds (as opposed to their common default setting of MIDI
1374 part 10 being a drumkit part and all other ones chromatic parts), in
1375 LS however one can switch between the first 16 MIDI instrument maps
1376 defined for the sampler
1377 - made it possible to create multiple sample channels even if the
1378 audio thread isn't running
1379 - fixed crash when removing channel with active voices (#116)
1380 - bugfix: on sample reference changes (instrument editor), only
1381 un-cache the respective sample if it's really not used by any
1382 sampler engine anymore
1383 - re-cache samples in case they were changed by an instrument editor,
1384 e.g. when a sample was added while playing (#82)
1385 - fixed hanging notes which occured when note-off event had the exact
1386 same time stamp as the voice's note-on event and occured both in the
1387 same audio fragment cycle (fixes bug #112)
1388 - added support for the "fine tune" and "pitch bend range"
1389 instrument-level gig parameters
1390 - fixed minor artifacts in pitch bend handling
1391 - added support for GS Reset SysEx message
1392 - allow gig files to use unlimited downward pitch shifting
1393 - added a limit check for upward pitch shifting
1394 - bugfix: sometimes, when playing a note twice fast, the second
1395 note was silent
1396 - fixed crash happening when a pitch bend event arrived at the
1397 same time a new instrument was loading
1398
1399 * LSCP server:
1400 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
1401 react on MIDI data arriving on certain sampler channels (so far only
1402 Note-On and Note-Off events are sent via this LSCP event)
1403 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1404 react on MIDI data arriving on certain MIDI input devices (so far only
1405 Note-On and Note-Off events are sent via this LSCP event)
1406 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
1407 SET DB_INSTRUMENT FILE_PATH
1408 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
1409 frontends to send MIDI messages to specific sampler channel
1410 - added two additional fields to GET FILE INSTRUMENT INFO command -
1411 KEY_BINDINGS and KEYSWITCH_BINDINGS
1412 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1413 was incorrect
1414 - Optimized the retrieval of the MIDI instrument mappings
1415 - added new LSCP command "SET VOICES" to globally alter the maximum
1416 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1417 be triggered respectively
1418 - added new LSCP command "SET STREAMS" to globally alter the maximum
1419 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1420 which will be triggered respectively
1421 - bugfix: retry if "select" returns EINTR (this fixes a crash when
1422 a gigedit file dialog is opened)
1423 - close all connections when LSCPServer is deleted
1424 - hard close of all sockets on exit
1425 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
1426 driver
1427
1428 * Bug fixes:
1429 - fixed a crash which occurs when removing a sampler channel waiting
1430 to start instrument loading after another channel
1431 - fixed a crash which occurs when removing a sampler channel with
1432 instrument loading in progress (bug #113)
1433 - fixed termination caused by uncaught exception when adding MIDI
1434 instrument with PERSISTENT load mode
1435 - fixed possible iterator invalidations when resetting the sampler
1436 - fixed memory leaks when issuing the following LSCP commands:
1437 GET AUDIO_OUTPUT_DRIVER INFO
1438 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
1439 GET MIDI_INPUT_DRIVER INFO
1440 GET MIDI_INPUT_DRIVER_PARAMETER INFO
1441 - fixed possible compilation error when sqlite is not present
1442 - fixed orphaned pointers when setting maximum voices limit (bug #118)
1443 - fixed crash when changing the audio output device of a sampler
1444 channel with loaded instrument and start playing notes
1445 - fixed endless loop in Engine::SuspendAll() (bug #120)
1446 - fixed a low-level atomic load function that was broken on 64-bit
1447 PowerPC, which probably could cause crashes on that platform
1448 - fixed a memory management error which could cause a crash when a
1449 plugin was unloaded
1450 - bugfix: two private structs had the same name, which could cause
1451 problems if the linker chose the wrong constructor
1452 - fixed low-level ConditionServer usage bug that caused lockups on
1453 Windows
1454
1455
1456 Version 0.5.1 (6 December 2007)
1457
1458 * packaging changes:
1459 - added autoconf checks for pthread library
1460 - added autoconf check for pthread bug found on certain NPTL-enabled
1461 glibc versions (see Gentoo bug report #194076)
1462 - added autoconf checks for MS Windows
1463
1464 * general changes:
1465 - bugfix: the thread used by an editor plugin didn't die when the
1466 editor closed
1467 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1468 out all the space. operator--() did not apply size_mask after
1469 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1470 order to avoid problems with the _NonVolatileReader functions.
1471 - bugfix: Stream.h: added a missing divide by BytesPerSample in
1472 GetWriteSpace(). Since this function is currently only used in
1473 the stream's qsort() compare function, it didn't trigger any
1474 bugs.
1475 - Resampler.h, Synthesizer.h: cubic interpolation now works in
1476 24bit mode too. Faster method to read 24bit words on little
1477 endian machines (x86): replaced 3 byte reads + shifts with a 1
1478 unaligned 32bit read and shift
1479 - experimental support for MS Windows (MIDI input via MME, AUDIO
1480 output via ASIO)
1481 - made handling of SIGINT signal (Ctrl-C) a bit more robust
1482 - support for monitoring the total number of active disk streams
1483 (new LSCP commands: GET TOTAL_STREAM_COUNT,
1484 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1485
1486 * AUDIO driver:
1487 - added Windows ASIO low latency audio driver
1488
1489 * MIDI driver:
1490 - added MME Windows MIDI driver
1491
1492 * LSCP server:
1493 - added support for Windows style path / filenames, however with
1494 forward slash path separators instead of backslash
1495 (i.e. "C:/foo/bar.gig")
1496 - allow naughty liblscp to send non-string device parameters within
1497 apostrophes as well
1498 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1499 "LIST FILE INSTRUMENTS <file>" and
1500 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1501 about an arbitrary instrument file on the system where the sampler is
1502 running on
1503
1504 Version 0.5.0 (15 October 2007)
1505
1506 * packaging changes:
1507 - config.h is not going to be installed along with liblinuxsampler's
1508 API header files anymore
1509 - only the API relevant header (and source) files will be exported to
1510 the Doxygen API documentation (explicitly listed in Doxyfile.in)
1511 - added completely new XCode project files for Mac OSX which is now
1512 capable to execute our autoconf environment, thus no need anymore
1513 to maintain the compile time configuration file (osx/version.h) for
1514 OSX manually (patch by Toshi Nagata)
1515 - fixed buggy boolean --enable-foo / --disable-foo configure script
1516 parameters
1517 - global.h now only covers global definitions that are needed for the
1518 C++ API header files, all implementation internal global definitions
1519 are now in global_private.h
1520 - atomic.h is not exposed to the C++ API anymore
1521 - no need to include config.h anymore for using LS's API header files
1522 - fixed warnings in API doc generation
1523
1524 * general changes:
1525 - replaced the old, confusing MIDI program change mechanism by a
1526 flexible MIDI instrument mapper which allows to map arbitrary
1527 (MIDI bank, MIDI program) pairs with arbitrary
1528 (engine type, instrument file, file index) triplets which will be
1529 loaded on the respective channel when such MIDI program change
1530 messages arrive, beside that, each entry allows to define a life-time
1531 strategy for the instrument, so the user can define whether the
1532 instrument should i.e. be permanently loaded (to be able to switch
1533 quickly among sounds) or i.e. loaded just on demand when the
1534 respective program change arrives (to safe RAM space), as well as a
1535 global volume factor for each entry, so the user can adjust the volume
1536 dynamic of his mapped instrument collection without having to modify
1537 the instrument files, also one can manage arbitrary amount of such
1538 MIDI instrument maps and assign each sampler channel individually
1539 a certain map, so that i.e. separation of normal instruments and
1540 drumkits is possible
1541 - new notification events for tracking changes to audio/MIDI devices,
1542 MIDI instrument maps, MIDI instruments, FX sends, global volume.
1543 - sampler was limited to load max. 200 instruments in the background
1544 due to a constant size RingBuffer FIFO which is now replaced by a
1545 dynamic (unlimited) size std::list FIFO
1546 - added FX sends, these allow to route audio signals to arbitrary audio
1547 output channels for being processed by external effect processors
1548 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1549 controllers
1550 - global (sampler wide) volume can now be controlled at runtime
1551 - Implemented new, improved notification system
1552 - fixed compilation errors regarding OSX
1553 (patch by Toshi Nagata)
1554 - implemented instruments database
1555 - added support for escape sequences to the instruments database
1556 - added highly experimental support for on-the-fly instrument editing
1557 within the sampler's process (by using instrument editor plugins),
1558 you'll notice the new "Registered instrument editors:" message on
1559 startup, added a new LSCP command:
1560 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1561 to spawn a matching instrument editor for the instrument on the
1562 given sampler channel, the plugin path can be overridden at compile
1563 time with ./configure --enable-plugin-dir=/some/dir
1564 - added experimental code for synchronizing instrument editors hosted
1565 in the sampler's process to safely edit instruments while playing
1566 without a crash (hopefully) by either suspending single regions
1567 wherever possible or if unavoidable whole engine(s)
1568 - fixed several issues in fundamental "Thread" class: set scheduling
1569 policy and priority on thread level, set a minimum stack size for
1570 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1571 threads simply inherited properties of starting thread instead of
1572 setting their own policy and priority
1573 - minor fix in our automatic stack trace mechanism on crashes, the
1574 main process did not wait for the stack trace process to finish
1575 its output
1576 - fixed some minor memory leaks
1577 - reenabled assembly features support, at the moment only for
1578 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1579 - minor assembly fix in x86 features detection (don't use the PIC
1580 register, to avoid relocations in the text segment at runtime)
1581 - POSIX callback functions of Thread.h are hidden
1582
1583 * MIDI driver:
1584 - dispatch bank select (MSB and LSB) messages
1585
1586 * audio driver:
1587 - the ALSA audio output driver parameters now reflect the correct
1588 parameter value ranges for the respective selected sound card
1589 (patch by Till Wimmer, a bit fixed and extended)
1590
1591 * Gigasampler format engine:
1592 - if a filter is used and EG2 finishes before EG1, let the voice
1593 die when EG2 has finished (this fixes a problem with clicks and
1594 voice starvation for some gigs)
1595 - playback is no longer disabled during instrument loading
1596 - all notes playing on a channel that changes its instrument keep
1597 playing with the old instrument until they get a note off
1598 command
1599 - EG fix: a release value of zero could cause noises or crash
1600 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1601 - EG fine tuning: when attack is zero the EG starts at a level
1602 above max sustain level, which means that there is a decay phase
1603 even if sustain is 100%
1604 - more EG fixes: the level could sometimes go below zero and cause
1605 noises or crashes
1606 - minor fix of EGDecay (patch by Toshi Nagata)
1607 - fixed compiler error when --enable-override-filter-type was
1608 supplied to the configure script (fixes #46)
1609 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1610 instead of a fix value
1611 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1612 127 (solo mode) only kill voices if the respective mode really
1613 changed
1614
1615 * LSCP server:
1616 - fixed compile time error for old Bison versions
1617 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1618 - parser now supports extended ASCII character set
1619 (up to ASCII code 255, i.e. includes now umlauts and accents)
1620 - filename arguments in LSCP commands now allow to use escape
1621 sequences, that is directly literal as one of: \', \", \\, \n, \r,
1622 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1623 code value like \xf2) (fixes bug #24)
1624 - the following LSCP commands now also support escape sequences for at
1625 least one of their text-based parameters (i.e. name, description):
1626 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1627 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1628 "SET DB_INSTRUMENT_DIRECTORY NAME",
1629 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1630 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1631 "FIND DB_INSTRUMENT_DIRECTORIES"
1632 - returns verbose syntax errors (line and column where syntax error
1633 occured, the unexpected character and the actually expected, possible
1634 character(s), the latter only if less than 5 possibilities)
1635 - made sure that LSCP syntax is not affected by gigedit locale
1636 settings
1637 - bugfix regarding strings parameter lists: all comma separated lists
1638 of strings were treated as being one string containing commas
1639 (fixes #57)
1640
1641 * Bug fixes:
1642 - fixed crash occurring on certain LSCP scripts (Bug 39)
1643 - another thread safety fix for lscp "load engine" and "set
1644 channel audio output device"
1645 - fixed a crash which occurs when reassigning the same engine
1646 on a sampler channel with connected MIDI device
1647 - fixed a crash which occurs when changing the number of ports of a MIDI
1648 device connected to a sampler channel to number less then or equal
1649 to the index of the port to which the sampler channel is connected.
1650 - The previous bindings were not been disconnected when altering
1651 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1652 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1653 - The active stream/voice count statistic was incorrect.
1654 - notification events were not been sent for some sampler
1655 channel changes
1656 - added default min and max values to restrict the number of allowed
1657 audio output channels and MIDI input ports
1658 - the connection to the PCM interface is now closed when destroying
1659 an audio output device
1660 - files with slash in their path or filename could not be loaded
1661
1662 * test cases:
1663 - updated and fixed (haven't been touched in a while)
1664
1665 Version 0.4.0 (24 November 2006)
1666
1667 * packaging changes:
1668 - changed deprecated copyright attribute to license; added ldconfig
1669 to post-(un)install steps; added devel package for liblinuxsampler;
1670 to linuxsampler.spec (RPM)
1671 - install necessary development header files for allowing 3rd party
1672 applications to link against liblinuxsampler
1673 - liblinuxsampler's API documentation can be generated with 'make docs'
1674 (Doxygen required)
1675 - added benchmark to automatically detect the best triangle LFO
1676 implementation (currently either an integer math solution or a
1677 di-harmonic approximation), automatic detection can be overriden
1678 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1679 configure script argument though (mandatory for cross-compilation)
1680 - do not automatically pick optimized gcc flags if the user already
1681 provided some on his own (as CXXFLAGS)
1682 - added compile time option to disable processing of All-Notes-Off MIDI
1683 messages
1684 - added compile time options to allow disabling the various audio and
1685 MIDI drivers
1686 - fixed automatic GCC CPU switch detection on PPC
1687 (patch by Ebrahim Mayat)
1688
1689 * Gigasampler format engine:
1690 - extensive synthesis optimization
1691 (reimplementation of EGs and LFO(s), removed synthesis parameter
1692 prerendering and the synthesis parameter matrix in general, splitting
1693 each audio fragment into subfragments now where each subfragment uses
1694 constant pitch and filter coefficients. The volume coefficient is
1695 linearly interpolated inside a subfragment, unless
1696 --disable-interpolate-volume is set.)
1697 - fine tuning of the EG modulation parameters
1698 - improved filter cutoff calculation by adding support for the
1699 following gig parameters: Cutoff freq (used when no cutoff
1700 controller is defined), Control invert, Minimum cutoff, Velocity
1701 curve and Velocity range. The keyboard tracking now scales
1702 cutoff frequency instead of resonance.
1703 - added support for gig parameter Resonance.
1704 - fixed bug in sysex handling (patch by Juan Linietsky)
1705 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1706 which can be overridden with --enable-global-attenuation
1707 - EG fixes: made the length of "attack hold" stage more
1708 accurate. Release stage can now start before attack stage
1709 ends. Cancel release didn't work when sustain was zero. Attack
1710 time now has a minimal value to prevent clicks.
1711 - fixed pitch changes larger than one octave
1712 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1713 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1714 all modes can be altered via standard GM messages, that is CC5 for
1715 altering portamento time, CC65 for enabling / disabling portamento
1716 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1717 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1718 parameter) and crossfade
1719 - added support for the "attenuation controller threshold" gig
1720 parameter
1721 - added smoothing of volume changes caused by control change
1722 messages
1723 - sample loop parameters are now taken from the DimensionRegion
1724 instead of the wave chunk
1725 - fixed keyswitching for v3 gigs with a number of keyswitch splits
1726 not equal to a power of two
1727 - reimplementation of the filter algorithm. The new filter is more
1728 accurate and supports all gig filter types, including bandreject
1729 and lowpass turbo.
1730 - real support for 24 bit samples - samples are not truncated to
1731 16 bits anymore
1732 - support for aftertouch (channel pressure, not polyphonic
1733 aftertouch)
1734 - LFO1 behaviour fixed (dampening from max volume instead of
1735 amplifying from 0)
1736
1737 * LSCP server:
1738 - fixed application exit on broken pipe error (fixes bug #20)
1739 - fixed the notification messages delay due to lack of
1740 network activity (fixes bug #26)
1741 - fixed parser bug which occured on space(s) within device parameters
1742 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1743
1744 * audio driver:
1745 - added aRts audio output driver (by no means RT safe)
1746
1747 * MIDI driver:
1748 - fixed legacy sysex code which caused dispatching of MIDI SysEx
1749 messages several times instead of once
1750 - API extension for MIDI drivers which already supply exact time stamps
1751 for events (i.e. for offline rendering based MIDI drivers)
1752 - added checks for bad MIDI data
1753
1754 * linuxsampler application:
1755 - show available sampler engine types on startup
1756
1757 * general changes:
1758 - support for muting sampler channels and solo mode of the same, two new
1759 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1760 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1761 introduced for this, the behavior is the same like on a mixer console
1762 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1763 --enable-process-muted-channels which can be used to enable the
1764 processing of muted channels.
1765 - support for sostenuto pedal
1766 - support for monitoring the total number of active voices
1767 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1768 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1769 - fixed some memory management errors
1770 - fixed some concurrency problems that could lead to crashes when
1771 LSCP commands were executed
1772 - fixed crash when instrument loading failed previously on the same
1773 sampler channel (fixes bug #36)
1774
1775 Version 0.3.3 (15 July 2005)
1776
1777 * packaging changes:
1778 - fixed compilation with gcc 4.0
1779
1780 * Gigasampler format engine:
1781 - LFO preprocessing was performed even though the respective LFO was
1782 disabled by the instrument patch (minor efficiency fix)
1783 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1784 for volume ramp downs in the same fragment (needed for current voice
1785 stealing implementation) then simply inform the user with a warning
1786 about possible click sounds and reduce the volume ramp down
1787 appropriately instead of cancelling the audio device connection
1788
1789 Version 0.3.2 (24 June 2005)
1790
1791 * packaging changes:
1792 - updated autotools build files to compile on OS X
1793 (conditional compilation of CoreMIDI and MidiShare drivers)
1794 - hand-crafted assembly optimization code can be disabled with
1795 './configure --disable-asm' (definitely not recommended)
1796 - fixed 'make dist' rule to include all necessary files
1797 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1798 (due to 'dist-bzip2' automake option)
1799
1800 * Gigasampler format engine:
1801 - support for the gig parameters for "release velocity response" curves
1802 - fine tuning of the EGADSR envelope
1803 - volume of release triggered samples now depends on note-on velocity,
1804 note length and gig parameter "release trigger decay" instead of
1805 note-off velocity.
1806 - revised voice stealing
1807 (fixes crash and endless loop caused by voice stealing)
1808 - don't reset scale tuning on instrument or audio output device change
1809 - handle key group conflicts right at the beginning of each fragment
1810 instead of when the respective voice is actually launched
1811 (fixes undefined behavior if stolen voices belonged to a key group -
1812 this case was followed by a "killed voice survived" error message)
1813 - fixed minor issue with null/silence samples
1814 (those stole voices even though they don't need a voice at all which
1815 resulted in "voice stealing didn't work out" messages)
1816 - don't reset volume, pan, pitch and MIDI controller values on
1817 instrument or audio output device change
1818
1819 * LSCP server:
1820 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1821 - fixed LSCP event "CHANNEL_INFO" notification
1822 (e.g. did not notify on volume changes or MIDI program change events)
1823
1824 * linuxsampler application:
1825 - added command line parameters --lscp-addr and --lscp-port to override
1826 default IP address and port of LSCP server
1827
1828 Version 0.3.1 (24 May 2005)
1829
1830 * initial release
