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

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

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

686
687 * Instruments DB:
688 - Fixed memory access bug of general DB access code which lead to
689 undefined behavior.
690 - Cleanup of instruments DB file creation and opening code.
691 - The instrument DB path of linuxsampler's --create-instruments-db argument
692 is now optional, if it is missing, then a default location is used.
693 - Added support for scanning SFZ (.sfz) files.
694 - Added support for scanning Sound Font (.sf2) files.
695 - Fixed undefined DB transaction behavior.
696
697 Version 2.0.0 (15 July 2015)
698

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

1006 incorrectly set to two. This caused silence in Cubase 5.
1007 - save engine type (gig, sfz or sf2) in plugin state
1008 - VST: when opening Fantasia, look for both 32 and 64 bit Java on
1009 64 bit Windows

1053 to them a la JACK, via the usual sampler APIs
1054 - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
1055 the driver will automatically connect to other CoreMIDI clients' ports
1056 (e.g. external MIDI devices being attached to the Mac)
1057 - added support for MIDI note on velocity filter
1058 - CoreMIDI: fixed memory deallocation error
1059 - Fixed variable underflow in VirtualMidiDevice, which caused graphical

1229 crashes and noise on such transitions).
1230 - ignore missing LADSPA paths without ignoring valid LADSPA paths
1231 (fixes #208)
1232 - Fixed bug in LSCP grammar definition which caused a statement like
1233 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1234 practically irrelevant, however it caused problems with the new LSCP
1235 shell's auto completion feature).
1236 - Fixed MIDI program change messages being ignored if quickly executed
1237 after each other (fixes #231).
1238

1254 directory of liblinuxsampler dll (look in the same directory and one
1255 directory above)
1256 - configure script fix: removed unconditional use of SSE
1257 - fixed building with sqlite installed in a non-standard directory
1258 - when cross-compiling, don't try to create instruments.db
1259 - fix for new mingw-w64 version, which has usleep
1260
1261 * general changes:
1262 - bugfix: on some POSIX systems instrument editor plugins refused to
1263 load as we used a non-portable Linux specific struct field
1264 (fixes bug #70, patch by Ronald Baljeu)
1265 - fixed endless loop which occured when loading an instrument editor
1266 plugin DLL on Windows systems failed
1267 - fixed memory leaks that occurred when liblinuxsampler was unloaded
1268 - optimized the SynchronizedConfig class so it doesn't wait
1269 unnecessarily long after an update
1270 - added support for notifying instrument editors on note-on / note-off
1271 events (e.g. to highlight the pressed keys on the virtual keyboard
1272 of gigedit)
1273 - added support for triggering notes by instrument editors (see above)
1274 - be verbose on DLL load errors (on Linux)
1275 - fixed di-harmonic triangle LFO implementation (this LFO implementation
1276 is only used by very few systems, most pick the int math
1277 implementation, which is usually faster)
1278 - fixes for audio drivers with varying buffer sizes
1279 - experimental support for running LinuxSampler as a DSSI, LV2 and
1280 VST plugin
1281 - notification events for stream/voice count statistics are now sent
1282 only when there are actual changes
1283 - added memory ordering constraints to improve stability on
1284 multi-core and multi-cpu systems
1285 - maximum voices and disk streams can now be altered at runtime
1286 - fixed CPU feature detection on x86_64 (maybe fixes #108)
1287 - automatic stacktrace mechanism is now turned off by default and can
1288 be switched on by command line option "--stacktrace" (the automatic
1289 stacktrace mechanism seems to be broken on most systems at the moment)
1290 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
1291 a pointer to the launched InstrumentEditor object
1292 - added optional 3rd party user data parameter for following
1293 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
1294 InstrumentEditor::Launch(),
1295 InstrumentManager::LaunchInstrumentEditor()
1296 - theoretical fix: made SynchronizedConfig follow C++0x memory
1297 model more strictly
1298 - fixes for using large audio device buffers
1299 - Windows: add the installation directory to the DLL search path
1300 when loading an editor plugin (solves problems with VST and
1301 gigedit on systems with other GTK versions installed)
1302 - updated linuxsampler man page
1303
1304 * audio driver:
1305 - removed the nonsense audio channel constraint (which was hard coded to
1306 max. 100 audio channels) for most audio drivers
1307 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
1308 opposed to the LSCP specs
1309 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
1310 reflected the wrong value
1311 - fixed a memory management bug in ASIO driver
1312 - Makefile fix: JACK_CFLAGS wasn't used
1313 - JACK: use jack_client_open instead of the deprecated
1314 jack_client_new
1315 - added (experimental) CoreAudio driver
1316 - applied old fixes to the ASIO driver that were included in the
1317 previous binary release but accidentally never committed to CVS
1318 (fixes #117)
1319 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
1320 win64)
1321 - VST: added support for sample rate and buffer size changes
1322 - VST: close editor (Fantasia) when the VST is removed
1323 - VST: avoid opening Fantasia more than once for each VST instance
1324 - VST: export main function as "main" on Linux too (fix for
1325 energyXT)
1326 - VST: changed number of output channels from one stereo to 16
1327 stereo
1328 - added channel routing, fxsends and midi maps to the settings
1329 stored in the plugin state
1330 - performance optimization of AudioChannel::MixTo() and
1331 AudioChannel::CopyTo() methods using GCC vector exensions
1332 (if available)
1333 - ASIO fixes: avoid initializing the device twice, avoid throwing
1334 exception when getting parameters from a disconnected device
1335
1336 * MIDI driver:
1337 - added JACK MIDI driver
1338 - dispatch bank select as ordinary CC as well, the user might seriously
1339 want to (mis)use it for some purpose ("fixed" in all current MIDI
1340 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
1341 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
1342 CoreMidi or AU
1343 - fixed mingw-w64 compilation error in MME driver
1344 - made program change handling in MIDI thread real-time safe by
1345 moving the logic to a non-RT thread
1346 - fixed minor memory leak in ALSA driver
1347
1348 * instruments database:
1349 - avoid time consuming samples scanning when adding instruments
1350 to the instruments database
1351 - added support for handling lost files in the instruments database
1352 - Implemented option for adding instruments in separate directories
1353 in the instruments database
1354 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
1355 - work-around for missing fnmatch function on Windows to make
1356 instrument database compilable
1357 - added instrument database support on Windows
1358 works with both standalone mode and VST plugin.
1359 the instruments DB file is located in
1360 %USERPROFILE%\.linuxsampler\instruments.db which allows different
1361 databases for each windows user
1362 if no DB is present it automatically creates the .linuxsampler subdir
1363 and then creates an empty DB
1364 - fixed recursive import, which was broken on Windows
1365
1366 * Gigasampler format engine:
1367 - fixed a memory leak that could happen when a channel was deleted
1368 while notes were playing
1369 - made it possible to load an instrument even if the audio thread
1370 isn't running
1371 - added partial support for the "Controller Triggered" MIDI rule,
1372 enough for piano gigs with pedal noise samples
1373 - minor fix: only mark FX sends as being modified if really the
1374 respective FX send MIDI controller was used
1375 - added support for GM global device volume SysEx message
1376 (can be selected at compile time to either apply globally to the
1377 whole sampler [default] or only to the sampler channels that are
1378 connected to the respective MIDI input port the SysEx message arrived
1379 on)
1380 - bugfix: notes triggered at position 0 in the audio buffer were
1381 sometimes wrongly killed in the same buffer, causing no sound to
1382 be played
1383 - added support for chromatic / drumkit mode Roland GS Sysex message
1384 which is usally used to switch a part between chromatic sounds and
1385 drumkit sounds (as opposed to their common default setting of MIDI
1386 part 10 being a drumkit part and all other ones chromatic parts), in
1387 LS however one can switch between the first 16 MIDI instrument maps
1388 defined for the sampler
1389 - made it possible to create multiple sample channels even if the
1390 audio thread isn't running
1391 - fixed crash when removing channel with active voices (#116)
1392 - bugfix: on sample reference changes (instrument editor), only
1393 un-cache the respective sample if it's really not used by any
1394 sampler engine anymore
1395 - re-cache samples in case they were changed by an instrument editor,
1396 e.g. when a sample was added while playing (#82)
1397 - fixed hanging notes which occured when note-off event had the exact
1398 same time stamp as the voice's note-on event and occured both in the
1399 same audio fragment cycle (fixes bug #112)
1400 - added support for the "fine tune" and "pitch bend range"
1401 instrument-level gig parameters
1402 - fixed minor artifacts in pitch bend handling
1403 - added support for GS Reset SysEx message
1404 - allow gig files to use unlimited downward pitch shifting
1405 - added a limit check for upward pitch shifting
1406 - bugfix: sometimes, when playing a note twice fast, the second
1407 note was silent
1408 - fixed crash happening when a pitch bend event arrived at the
1409 same time a new instrument was loading
1410
1411 * LSCP server:
1412 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
1413 react on MIDI data arriving on certain sampler channels (so far only
1414 Note-On and Note-Off events are sent via this LSCP event)
1415 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1416 react on MIDI data arriving on certain MIDI input devices (so far only
1417 Note-On and Note-Off events are sent via this LSCP event)
1418 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
1419 SET DB_INSTRUMENT FILE_PATH
1420 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
1421 frontends to send MIDI messages to specific sampler channel
1422 - added two additional fields to GET FILE INSTRUMENT INFO command -
1423 KEY_BINDINGS and KEYSWITCH_BINDINGS
1424 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1425 was incorrect
1426 - Optimized the retrieval of the MIDI instrument mappings
1427 - added new LSCP command "SET VOICES" to globally alter the maximum
1428 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1429 be triggered respectively
1430 - added new LSCP command "SET STREAMS" to globally alter the maximum
1431 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1432 which will be triggered respectively
1433 - bugfix: retry if "select" returns EINTR (this fixes a crash when
1434 a gigedit file dialog is opened)
1435 - close all connections when LSCPServer is deleted
1436 - hard close of all sockets on exit
1437 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
1438 driver
1439
1440 * Bug fixes:
1441 - fixed a crash which occurs when removing a sampler channel waiting
1442 to start instrument loading after another channel
1443 - fixed a crash which occurs when removing a sampler channel with
1444 instrument loading in progress (bug #113)
1445 - fixed termination caused by uncaught exception when adding MIDI
1446 instrument with PERSISTENT load mode
1447 - fixed possible iterator invalidations when resetting the sampler
1448 - fixed memory leaks when issuing the following LSCP commands:
1449 GET AUDIO_OUTPUT_DRIVER INFO
1450 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
1451 GET MIDI_INPUT_DRIVER INFO
1452 GET MIDI_INPUT_DRIVER_PARAMETER INFO
1453 - fixed possible compilation error when sqlite is not present
1454 - fixed orphaned pointers when setting maximum voices limit (bug #118)
1455 - fixed crash when changing the audio output device of a sampler
1456 channel with loaded instrument and start playing notes
1457 - fixed endless loop in Engine::SuspendAll() (bug #120)
1458 - fixed a low-level atomic load function that was broken on 64-bit
1459 PowerPC, which probably could cause crashes on that platform
1460 - fixed a memory management error which could cause a crash when a
1461 plugin was unloaded
1462 - bugfix: two private structs had the same name, which could cause
1463 problems if the linker chose the wrong constructor
1464 - fixed low-level ConditionServer usage bug that caused lockups on
1465 Windows
1466
1467
1468 Version 0.5.1 (6 December 2007)
1469
1470 * packaging changes:
1471 - added autoconf checks for pthread library
1472 - added autoconf check for pthread bug found on certain NPTL-enabled
1473 glibc versions (see Gentoo bug report #194076)
1474 - added autoconf checks for MS Windows
1475
1476 * general changes:
1477 - bugfix: the thread used by an editor plugin didn't die when the
1478 editor closed
1479 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1480 out all the space. operator--() did not apply size_mask after
1481 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1482 order to avoid problems with the _NonVolatileReader functions.
1483 - bugfix: Stream.h: added a missing divide by BytesPerSample in
1484 GetWriteSpace(). Since this function is currently only used in
1485 the stream's qsort() compare function, it didn't trigger any
1486 bugs.
1487 - Resampler.h, Synthesizer.h: cubic interpolation now works in
1488 24bit mode too. Faster method to read 24bit words on little
1489 endian machines (x86): replaced 3 byte reads + shifts with a 1
1490 unaligned 32bit read and shift
1491 - experimental support for MS Windows (MIDI input via MME, AUDIO
1492 output via ASIO)
1493 - made handling of SIGINT signal (Ctrl-C) a bit more robust
1494 - support for monitoring the total number of active disk streams
1495 (new LSCP commands: GET TOTAL_STREAM_COUNT,
1496 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1497
1498 * AUDIO driver:
1499 - added Windows ASIO low latency audio driver
1500
1501 * MIDI driver:
1502 - added MME Windows MIDI driver
1503
1504 * LSCP server:
1505 - added support for Windows style path / filenames, however with
1506 forward slash path separators instead of backslash
1507 (i.e. "C:/foo/bar.gig")
1508 - allow naughty liblscp to send non-string device parameters within
1509 apostrophes as well
1510 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1511 "LIST FILE INSTRUMENTS <file>" and
1512 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1513 about an arbitrary instrument file on the system where the sampler is
1514 running on
1515
1516 Version 0.5.0 (15 October 2007)
1517
1518 * packaging changes:
1519 - config.h is not going to be installed along with liblinuxsampler's
1520 API header files anymore
1521 - only the API relevant header (and source) files will be exported to
1522 the Doxygen API documentation (explicitly listed in Doxyfile.in)
1523 - added completely new XCode project files for Mac OSX which is now
1524 capable to execute our autoconf environment, thus no need anymore
1525 to maintain the compile time configuration file (osx/version.h) for
1526 OSX manually (patch by Toshi Nagata)
1527 - fixed buggy boolean --enable-foo / --disable-foo configure script
1528 parameters
1529 - global.h now only covers global definitions that are needed for the
1530 C++ API header files, all implementation internal global definitions
1531 are now in global_private.h
1532 - atomic.h is not exposed to the C++ API anymore
1533 - no need to include config.h anymore for using LS's API header files
1534 - fixed warnings in API doc generation
1535
1536 * general changes:
1537 - replaced the old, confusing MIDI program change mechanism by a
1538 flexible MIDI instrument mapper which allows to map arbitrary
1539 (MIDI bank, MIDI program) pairs with arbitrary
1540 (engine type, instrument file, file index) triplets which will be
1541 loaded on the respective channel when such MIDI program change
1542 messages arrive, beside that, each entry allows to define a life-time
1543 strategy for the instrument, so the user can define whether the
1544 instrument should i.e. be permanently loaded (to be able to switch
1545 quickly among sounds) or i.e. loaded just on demand when the
1546 respective program change arrives (to safe RAM space), as well as a
1547 global volume factor for each entry, so the user can adjust the volume
1548 dynamic of his mapped instrument collection without having to modify
1549 the instrument files, also one can manage arbitrary amount of such
1550 MIDI instrument maps and assign each sampler channel individually
1551 a certain map, so that i.e. separation of normal instruments and
1552 drumkits is possible
1553 - new notification events for tracking changes to audio/MIDI devices,
1554 MIDI instrument maps, MIDI instruments, FX sends, global volume.
1555 - sampler was limited to load max. 200 instruments in the background
1556 due to a constant size RingBuffer FIFO which is now replaced by a
1557 dynamic (unlimited) size std::list FIFO
1558 - added FX sends, these allow to route audio signals to arbitrary audio
1559 output channels for being processed by external effect processors
1560 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1561 controllers
1562 - global (sampler wide) volume can now be controlled at runtime
1563 - Implemented new, improved notification system
1564 - fixed compilation errors regarding OSX
1565 (patch by Toshi Nagata)
1566 - implemented instruments database
1567 - added support for escape sequences to the instruments database
1568 - added highly experimental support for on-the-fly instrument editing
1569 within the sampler's process (by using instrument editor plugins),
1570 you'll notice the new "Registered instrument editors:" message on
1571 startup, added a new LSCP command:
1572 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1573 to spawn a matching instrument editor for the instrument on the
1574 given sampler channel, the plugin path can be overridden at compile
1575 time with ./configure --enable-plugin-dir=/some/dir
1576 - added experimental code for synchronizing instrument editors hosted
1577 in the sampler's process to safely edit instruments while playing
1578 without a crash (hopefully) by either suspending single regions
1579 wherever possible or if unavoidable whole engine(s)
1580 - fixed several issues in fundamental "Thread" class: set scheduling
1581 policy and priority on thread level, set a minimum stack size for
1582 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1583 threads simply inherited properties of starting thread instead of
1584 setting their own policy and priority
1585 - minor fix in our automatic stack trace mechanism on crashes, the
1586 main process did not wait for the stack trace process to finish
1587 its output
1588 - fixed some minor memory leaks
1589 - reenabled assembly features support, at the moment only for
1590 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1591 - minor assembly fix in x86 features detection (don't use the PIC
1592 register, to avoid relocations in the text segment at runtime)
1593 - POSIX callback functions of Thread.h are hidden
1594
1595 * MIDI driver:
1596 - dispatch bank select (MSB and LSB) messages
1597
1598 * audio driver:
1599 - the ALSA audio output driver parameters now reflect the correct
1600 parameter value ranges for the respective selected sound card
1601 (patch by Till Wimmer, a bit fixed and extended)
1602
1603 * Gigasampler format engine:
1604 - if a filter is used and EG2 finishes before EG1, let the voice
1605 die when EG2 has finished (this fixes a problem with clicks and
1606 voice starvation for some gigs)
1607 - playback is no longer disabled during instrument loading
1608 - all notes playing on a channel that changes its instrument keep
1609 playing with the old instrument until they get a note off
1610 command
1611 - EG fix: a release value of zero could cause noises or crash
1612 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1613 - EG fine tuning: when attack is zero the EG starts at a level
1614 above max sustain level, which means that there is a decay phase
1615 even if sustain is 100%
1616 - more EG fixes: the level could sometimes go below zero and cause
1617 noises or crashes
1618 - minor fix of EGDecay (patch by Toshi Nagata)
1619 - fixed compiler error when --enable-override-filter-type was
1620 supplied to the configure script (fixes #46)
1621 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1622 instead of a fix value
1623 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1624 127 (solo mode) only kill voices if the respective mode really
1625 changed
1626
1627 * LSCP server:
1628 - fixed compile time error for old Bison versions
1629 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1630 - parser now supports extended ASCII character set
1631 (up to ASCII code 255, i.e. includes now umlauts and accents)
1632 - filename arguments in LSCP commands now allow to use escape
1633 sequences, that is directly literal as one of: \', \", \\, \n, \r,
1634 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1635 code value like \xf2) (fixes bug #24)
1636 - the following LSCP commands now also support escape sequences for at
1637 least one of their text-based parameters (i.e. name, description):
1638 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1639 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1640 "SET DB_INSTRUMENT_DIRECTORY NAME",
1641 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1642 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1643 "FIND DB_INSTRUMENT_DIRECTORIES"
1644 - returns verbose syntax errors (line and column where syntax error
1645 occured, the unexpected character and the actually expected, possible
1646 character(s), the latter only if less than 5 possibilities)
1647 - made sure that LSCP syntax is not affected by gigedit locale
1648 settings
1649 - bugfix regarding strings parameter lists: all comma separated lists
1650 of strings were treated as being one string containing commas
1651 (fixes #57)
1652
1653 * Bug fixes:
1654 - fixed crash occurring on certain LSCP scripts (Bug 39)
1655 - another thread safety fix for lscp "load engine" and "set
1656 channel audio output device"
1657 - fixed a crash which occurs when reassigning the same engine
1658 on a sampler channel with connected MIDI device
1659 - fixed a crash which occurs when changing the number of ports of a MIDI
1660 device connected to a sampler channel to number less then or equal
1661 to the index of the port to which the sampler channel is connected.
1662 - The previous bindings were not been disconnected when altering
1663 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1664 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1665 - The active stream/voice count statistic was incorrect.
1666 - notification events were not been sent for some sampler
1667 channel changes
1668 - added default min and max values to restrict the number of allowed
1669 audio output channels and MIDI input ports
1670 - the connection to the PCM interface is now closed when destroying
1671 an audio output device
1672 - files with slash in their path or filename could not be loaded
1673
1674 * test cases:
1675 - updated and fixed (haven't been touched in a while)
1676
1677 Version 0.4.0 (24 November 2006)
1678
1679 * packaging changes:
1680 - changed deprecated copyright attribute to license; added ldconfig
1681 to post-(un)install steps; added devel package for liblinuxsampler;
1682 to linuxsampler.spec (RPM)
1683 - install necessary development header files for allowing 3rd party
1684 applications to link against liblinuxsampler
1685 - liblinuxsampler's API documentation can be generated with 'make docs'
1686 (Doxygen required)
1687 - added benchmark to automatically detect the best triangle LFO
1688 implementation (currently either an integer math solution or a
1689 di-harmonic approximation), automatic detection can be overriden
1690 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1691 configure script argument though (mandatory for cross-compilation)
1692 - do not automatically pick optimized gcc flags if the user already
1693 provided some on his own (as CXXFLAGS)
1694 - added compile time option to disable processing of All-Notes-Off MIDI
1695 messages
1696 - added compile time options to allow disabling the various audio and
1697 MIDI drivers
1698 - fixed automatic GCC CPU switch detection on PPC
1699 (patch by Ebrahim Mayat)
1700
1701 * Gigasampler format engine:
1702 - extensive synthesis optimization
1703 (reimplementation of EGs and LFO(s), removed synthesis parameter
1704 prerendering and the synthesis parameter matrix in general, splitting
1705 each audio fragment into subfragments now where each subfragment uses
1706 constant pitch and filter coefficients. The volume coefficient is
1707 linearly interpolated inside a subfragment, unless
1708 --disable-interpolate-volume is set.)
1709 - fine tuning of the EG modulation parameters
1710 - improved filter cutoff calculation by adding support for the
1711 following gig parameters: Cutoff freq (used when no cutoff
1712 controller is defined), Control invert, Minimum cutoff, Velocity
1713 curve and Velocity range. The keyboard tracking now scales
1714 cutoff frequency instead of resonance.
1715 - added support for gig parameter Resonance.
1716 - fixed bug in sysex handling (patch by Juan Linietsky)
1717 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1718 which can be overridden with --enable-global-attenuation
1719 - EG fixes: made the length of "attack hold" stage more
1720 accurate. Release stage can now start before attack stage
1721 ends. Cancel release didn't work when sustain was zero. Attack
1722 time now has a minimal value to prevent clicks.
1723 - fixed pitch changes larger than one octave
1724 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1725 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1726 all modes can be altered via standard GM messages, that is CC5 for
1727 altering portamento time, CC65 for enabling / disabling portamento
1728 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1729 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1730 parameter) and crossfade
1731 - added support for the "attenuation controller threshold" gig
1732 parameter
1733 - added smoothing of volume changes caused by control change
1734 messages
1735 - sample loop parameters are now taken from the DimensionRegion
1736 instead of the wave chunk
1737 - fixed keyswitching for v3 gigs with a number of keyswitch splits
1738 not equal to a power of two
1739 - reimplementation of the filter algorithm. The new filter is more
1740 accurate and supports all gig filter types, including bandreject
1741 and lowpass turbo.
1742 - real support for 24 bit samples - samples are not truncated to
1743 16 bits anymore
1744 - support for aftertouch (channel pressure, not polyphonic
1745 aftertouch)
1746 - LFO1 behaviour fixed (dampening from max volume instead of
1747 amplifying from 0)
1748
1749 * LSCP server:
1750 - fixed application exit on broken pipe error (fixes bug #20)
1751 - fixed the notification messages delay due to lack of
1752 network activity (fixes bug #26)
1753 - fixed parser bug which occured on space(s) within device parameters
1754 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1755
1756 * audio driver:
1757 - added aRts audio output driver (by no means RT safe)
1758
1759 * MIDI driver:
1760 - fixed legacy sysex code which caused dispatching of MIDI SysEx
1761 messages several times instead of once
1762 - API extension for MIDI drivers which already supply exact time stamps
1763 for events (i.e. for offline rendering based MIDI drivers)
1764 - added checks for bad MIDI data
1765
1766 * linuxsampler application:
1767 - show available sampler engine types on startup
1768
1769 * general changes:
1770 - support for muting sampler channels and solo mode of the same, two new
1771 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1772 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1773 introduced for this, the behavior is the same like on a mixer console
1774 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1775 --enable-process-muted-channels which can be used to enable the
1776 processing of muted channels.
1777 - support for sostenuto pedal
1778 - support for monitoring the total number of active voices
1779 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1780 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1781 - fixed some memory management errors
1782 - fixed some concurrency problems that could lead to crashes when
1783 LSCP commands were executed
1784 - fixed crash when instrument loading failed previously on the same
1785 sampler channel (fixes bug #36)
1786
1787 Version 0.3.3 (15 July 2005)
1788
1789 * packaging changes:
1790 - fixed compilation with gcc 4.0
1791
1792 * Gigasampler format engine:
1793 - LFO preprocessing was performed even though the respective LFO was
1794 disabled by the instrument patch (minor efficiency fix)
1795 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1796 for volume ramp downs in the same fragment (needed for current voice
1797 stealing implementation) then simply inform the user with a warning
1798 about possible click sounds and reduce the volume ramp down
1799 appropriately instead of cancelling the audio device connection
1800
1801 Version 0.3.2 (24 June 2005)
1802
1803 * packaging changes:
1804 - updated autotools build files to compile on OS X
1805 (conditional compilation of CoreMIDI and MidiShare drivers)
1806 - hand-crafted assembly optimization code can be disabled with
1807 './configure --disable-asm' (definitely not recommended)
1808 - fixed 'make dist' rule to include all necessary files
1809 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1810 (due to 'dist-bzip2' automake option)
1811
1812 * Gigasampler format engine:
1813 - support for the gig parameters for "release velocity response" curves
1814 - fine tuning of the EGADSR envelope
1815 - volume of release triggered samples now depends on note-on velocity,
1816 note length and gig parameter "release trigger decay" instead of
1817 note-off velocity.
1818 - revised voice stealing
1819 (fixes crash and endless loop caused by voice stealing)
1820 - don't reset scale tuning on instrument or audio output device change
1821 - handle key group conflicts right at the beginning of each fragment
1822 instead of when the respective voice is actually launched
1823 (fixes undefined behavior if stolen voices belonged to a key group -
1824 this case was followed by a "killed voice survived" error message)
1825 - fixed minor issue with null/silence samples
1826 (those stole voices even though they don't need a voice at all which
1827 resulted in "voice stealing didn't work out" messages)
1828 - don't reset volume, pan, pitch and MIDI controller values on
1829 instrument or audio output device change
1830
1831 * LSCP server:
1832 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1833 - fixed LSCP event "CHANNEL_INFO" notification
1834 (e.g. did not notify on volume changes or MIDI program change events)
1835
1836 * linuxsampler application:
1837 - added command line parameters --lscp-addr and --lscp-port to override
1838 default IP address and port of LSCP server
1839
1840 Version 0.3.1 (24 May 2005)
1841
1842 * initial release
