File size: 95995 byte(s)
* NKSP: Implemented built-in script function "set_rpn()".

* NKSP: Implemented built-in script function "set_nrpn()".

* Bumped version (2.1.1.svn31).

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

434 - Implemented built-in script function "inc()".
435 - Implemented built-in script function "dec()".
436 - NKSP language fix: division expressions were evaluated too often.
437 - NKSP language fix: string concatenation operator was right
438 associative instead of left (to right).
439 - NKSP language correction: allow empty statements in entire language
440 (i.e. "if end if").

455 - Fixed all change_*() built-in script functions to apply their
456 synthesis parameter changes immediately in case the respective note
457 was triggered at the same time, instead of scheduling the parameter
458 change, especially because it would cause some parameter types's
459 changes either to be ramped (i.e. change_vol()) or other types even
460 to have not effect at all (i.e. change_attack()).
461 - Implemented built-in script function "sh_left()".
462 - Implemented built-in script function "sh_right()".
463 - Implemented built-in script function "min()".
464 - Implemented built-in script function "max()".

466 was loaded.
467 - NKSP built-in wait() script function: abort script execution if
468 a negative or zero wait time was passed as argument (since this is
469 a common indication of a bug either of the script or even of the
470 engine, which could lead to RT instability or even worse).
471 - ScriptVM: Implemented automatic suspension of RT safety
472 threatening scripts.

485 - Implemented built-in script function "fade_out()".
486 - Fixed acceptance of wrong data type of parameters passed to built-in
487 script functions "change_vol()", "change_tune()", "change_pan()",
488 "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
489 "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",

491 - Added built-in script function "get_event_par()" and implemented some
492 of its possible parameter selections.

494 of its possible parameter selections.
495 - Fixed a bunch of scheduler time related bugs.
496 - Fixed polyphonic variables not being reset to zero after usage.
497 - Built-in "ignore_event()" function: argument is now optional, like with
498 built-in function "ignore_controller()".
499 - Implemented built-in script function "change_velo()".
500 - Implemented built-in script function "change_note()".
501 - Adjusted behavior of "change_vol()" and "change_tune()" to a more
502 intuitive behavior if used in combination with "change_vol_time()" or
503 "change_tune_time()" respectively: now tuning/volume changes are only
504 assigned (without delay) immediately to a new note if the respective
505 timing function has not been called before, otherwise the volume/tuning
506 changes are automatically faded (before, only the event's time stamp was
507 relevant).
508 - Implemented built-in script function "array_equal()".
509 - Implemented built-in script function "search()".
510 - Implemented built-in script function "sort()".
511 - NKSP Fix: Never suspend "init" event handlers.

513 available for gig format engine).
514 - Added built-in script constant "$NKSP_LINEAR".
515 - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
516 - Implemented built-in script function "change_vol_curve()".
517 - Implemented built-in script function "change_tune_curve()".
518 - built-in "play_note()" function now supports a sample playback start
519 offset with argument 3, where special value -1 means to use the regular
520 sample offset as defined by the instrument file.
521 - Built-in array variable %KEY_DOWN[] is now a read-only variable.
522 - Built-in variable $EVENT_NOTE is now a read-only variable.
523 - Built-in variable $EVENT_VELOCITY is now a read-only variable.
524 - built-in "play_note()" function now accepts -2 for its fourth argument
525 (note duration) which means the life time of the note shall be sticked
526 to the requested note number of argument 1.
527 - Fix: built-in "play_note()" function now returns 0 as result value if
528 -1 was passed for its fourth argument (note duration) and the respective
529 parent note is already gone.
530 - Implemented built-in script function "change_play_pos()".
531 - NKSP language: Added support for user declared const array variables.
532 - NKSP language: Raise parser warning if array variable is accessed with
533 an index that exceeds the array's size.
534 - NKSP language fix: Unknown characters were not handled correctly.
535 - NKSP language: Added support for "synchronized .. end synchronized"
536 code blocks.
537 - Implemented built-in script function "abort()" which allows to abort
538 another script handler by passing its callback ID.
539 - Fixed potential memory access bug and potential undefined behavior of
540 "init" event handlers.
541 - Print a time stamp along to each call of built-in function "message()".
542 - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
543 to retrieve all code blocks filtered out by the preprocessor.

550 - Added built-in constant $CALLBACK_STATUS_QUEUE.
551 - Added built-in constant $CALLBACK_STATUS_RUNNING.
552 - Removed max. value limitation of built-in functions "change_attack()",
553 "change_decay()" and "change_release()" to i.e. allow passing 2000000
554 for doubling the respective time.
555 - NKSP script editor syntax highlighting API: Fixed app termination due
556 to a lexer start condition stack underrun.
557 - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
558 USE_CODE_IF_NOT() preprocessor statements.
559 - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
560 can be set to disable all subsequent built-in "message()" function calls
561 on preprocessor level.
562 - Implemented built-in script function "change_sustain()".
563 - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
564 to avoid the editor app to crash on ill-formed text input.

579 is now optional, if it is missing, then a default location is used.
580 - Added support for scanning SFZ (.sfz) files.
581 - Added support for scanning Sound Font (.sf2) files.
582 - Fixed undefined DB transaction behavior.

596 - minor Makefile fix for building lscpparser when build and source
597 directories are separate
598 - Mac OS X: made it possible to specify plugin installation dir to
599 configure
600 - Mac OS X: Makefile fix for the install-strip target
601 - fixed compilation with gcc 4.7
602 - fixed configure script error with old autoconf versions
603 - lsatomic.h: use gcc provided atomic functions if building with
604 gcc 4.7 and C++11
605 - modernized configure script
606 - fixed linkage error when building with
607 LDFLAGS="-Wl,--no-undefined" (#190)
608 - fixed compilation with Clang 3.2
609 - removed usage of deprecated Automake variable INCLUDES
610 - fixed building with C++11
611 - build fix: ChangeFlagRelaxed.h was missing in makefile
612 - build fix: libsndfile compiler flags were missing in some
613 makefiles
614 - fix for building with bison 3.0 (#202)
615 - Mac OS X: added temporary hack allowing to spawn gigedit as callback
616 on the process's main thread
617 - fixed build error on newer MinGW
618 - support building with older jack versions

622 in order to get rid of warnings from automake 1.14
623
624 * general changes:
625 - Refactoring: moved the independent code from
626 the Gigasampler format engine to base classes
627 - command line option '--profile' is currently disabled, since the
628 respective profiling code is currently broken
629 - Introduced support for optional environment variable
630 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
631 where the sampler shall look for instrument editor plugins
632 (patch by Luis Garrido, slightly modified).
633 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
634 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
635 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
636 note (in this implementation of the sampler its simply hard routed to
637 the 1st effect send of the sampler channel, no matter what the actual
638 effect type is)
639 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
640 note (in this implementation of the sampler its simply hard routed to
641 the 2nd effect send of the sampler channel, no matter what the actual
642 effect type is)
643 - implemented support for internal LADSPA effects
644 - raised limit of program change queue from 100 to 512
645 (as suggested by Alex Stone)
646 - implemented sine LFO, pulse LFO and saw LFO
647 - experimental support for per voice equalization
648 - added command line option --exec-after-init
649 - Introduced new C++ API method:
650 EngineChannel::InstrumentFileName(int index)
651 allowing to retrieve the whole list of files used for the loaded
652 instrument on an engine channel (a.k.a. part). Some GigaStudio
653 instruments for example are splitted over several files like
654 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
655 - Added new C++ API method Sampler::GetGlobalMaxVoices().
656 - Added new C++ API method Sampler::GetGlobalMaxStreams().
657 - Added new C++ API method Sampler::SetGlobalMaxVoices().
658 - Added new C++ API method Sampler::SetGlobalMaxStreams().
659 - Various "const" and "restrict" optimizations.
660 - all engines: add pan CC value to instrument pan parameter before
661 applying panning, instead of using two separate pan functions in
662 series (#182)
663 - added a lock guard class for exception safe mutex handling and
664 used it everywhere appropriate
665 - Immediately apply scale tuning changes to active voices.
666 - Exposed scale tuning to C++ API (along to the already existing standard
667 SysEx way).
668 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
669 and broken for ppc64. (Seq_cst loads and stores are actually not
670 used in LS, so the bug wasn't noticable.)
671 - lsatomic.h: added ARMv7 support
672 - Added support for multiple MIDI input ports per sampler channel (and
673 added various new C++ methods for this new feature / design change, old
674 C++ API methods for managing SamplerChannel's MIDI inputs are now marked
675 as deprecated but are still there and should provide full behavior
676 backward compatibility).
677 - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
678 unsafe and caused compilation error with clang 2.x).
679 - Bugfix: only process the latest MIDI program change event.
680 - Introducing the LSCP shell, which provides convenient control of the
681 sampler from the command line by providing LSCP aware features.
682 - VirtualMidiDevice: Added support for program change.
683 - VirtualMidiDevice: Added support for bank select (MSB & LSB).
684 - VirtualMidiDevice: Added support for pitch bend.
685 - Aftertouch: extended API to explicitly handle channel pressure and
686 polyphonic key pressure events (so far polyphonic pressure was not
687 supported at all, and channel pressure was rerouted as CC128 but not
688 used so far).
689 - Added initial support for real-time instrument scripts. The script VM
690 code is shared by all sampler engine implemementations, however only the
691 gig file format currently provides support for storing instrument scripts
692 (as LinuxSampler extension to the original GigaStudio 4 format).
693

699 key
700 - bugfix: pitch LFO controller "internal+aftertouch" was broken
701 - bugfix: filter keyboard tracking was broken
702 - filter performance fix (an unnecessary copy was made of the
703 filter parameters in each sub fragment)
704 - handle special case when pan parameter in gig file has max or
705 min value
706 - Exclusive Groups: don't ever stop voices of the same note,
707 doesn't sound naturally with a drumkit
708 - fixed EG1 modulation when attack or release is zero
709 - Fixed support for 'aftertouch' attenuation controller.
710 - Fixed crash that happened with velocity split sounds under certain
711 conditions (see also previous commit on libgig).
712 - fixed behaviour of filter LFO
713
714 * SFZ format engine:

744 - added support for loop_mode=one_shot
745 - fixed playback of 16 bit wav files on big endian CPUs
746 - added support for Ogg Vorbis sample files
747 - use loop markers from sample file if loop_start and loop_end are
748 not set in sfz file
749 - implemeted filters. Filter types: lowpass, bandpass, bandreject
750 and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,
751 cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
752 cutoff_cc, cutoff_chanaft.
753 - bugfix: zero ampeg_sustain didn't work

890 - Listen to all interfaces on Mac OS X (INADDR_ANY)
891 - VST bugfix: If the host called resume() before and after
892 changing sample rate or block size, the number of channels was
893 incorrectly set to two. This caused silence in Cubase 5.
894 - save engine type (gig, sfz or sf2) in plugin state

939 which allows to retrieve the list of CoreMIDI clients / ports and to connect
940 to them a la JACK, via the usual sampler APIs
941 - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
942 the driver will automatically connect to other CoreMIDI clients' ports
943 (e.g. external MIDI devices being attached to the Mac)
944 - added support for MIDI note on velocity filter
945 - CoreMIDI: fixed memory deallocation error
946 - Fixed variable underflow in VirtualMidiDevice, which caused graphical
947 virtual keyboards in frontends / instrument editors being stuck.
948 - Bugfix in VirtualMidiDevice: process note on with velocity 0 as note off.

1017 - Added support for moving cursor left/right with arrow keys.
1018 - Added support for built-in LSCP reference documentation, which will
1019 automatically show the relevant LSCP reference section on screen as soon

1067 "gig_set_dim_zone()" now also accept an array of event IDs as argument
1068 (i.e. return value of new script function "by_marks()").
1069 - Pass/preserve polyphonic variable data from respective "note" event
1070 handler to "release" event handler.
1071 - Fixed crash when using built-in script function "by_marks()".
1072

1077 channel to a different engine type
1078 - fixed crash when deleting a sampler channel or changing engine
1079 type while an instrument load was in progress
1080 - bugfix: playing a note while changing the instrument could cause
1081 a crash, or give "Handing back unknown region" error messages
1082 - bugfix: calling SET VOICES (which Fantasia does on start and
1083 refresh) could cause instruments to be unloaded
1084 - Mac OS X: fixed name collision of enum in EffectControl and
1085 wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
1086 - Mac OS X: fixed hanging threads
1087 - Windows: disabled the previous thread fix on non-Mac systems, as
1088 it caused hanging threads on Windows
1089 - Fixed possible crashes due to corrupted MIDI/audio device list
1090 after MIDI/audio device creation failure
1091 - When creating MIDI instrument map entries with "PERSISTENT" type, the
1092 instruments were uselessly precached with zero samples, however it still
1093 took the full preloading time and on 1st program change the respective
1094 instrument was completely reloaded again.
1095 - fixed handling of rapid bank select and program change messages
1096 sent to the same sampler channel (patch from the Open Octave
1097 project, slightly adjusted)

1112 playing a note in a key group
1113 - fixed erroneous error message piping in VoiceBase.h
1114 (labelled "Disk stream not available in time")
1115 - Update effects on sample rate & period size changes (to avoid
1116 crashes and noise on such transitions).
1117 - ignore missing LADSPA paths without ignoring valid LADSPA paths
1118 (fixes #208)
1119 - Fixed bug in LSCP grammar definition which caused a statement like
1120 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1121 practically irrelevant, however it caused problems with the new LSCP
1122 shell's auto completion feature).
1123 - Fixed MIDI program change messages being ignored if quickly executed
1124 after each other (fixes #231).
1125
1126 Version 1.0.0 (31 July 2009)
1127
1128 * packaging changes:
1129 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
1130 causing e.g. the libgig test to fail when
1131 "./configure --disable-jack-driver" was used
1132 (patch by Alexis Ballier)
1133 - fixed compilation with gcc 4.3
1134 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)

1138 - fixed building with libgig installed in a non-standard directory
1139 - minor fix in configure for mmsystem.h detection on MinGW
1140 - Windows: look for editor plugins and Fantasia using base
1141 directory of liblinuxsampler dll (look in the same directory and one
1142 directory above)
1143 - configure script fix: removed unconditional use of SSE
1144 - fixed building with sqlite installed in a non-standard directory
1145 - when cross-compiling, don't try to create instruments.db
1146 - fix for new mingw-w64 version, which has usleep
1147
1148 * general changes:
1149 - bugfix: on some POSIX systems instrument editor plugins refused to
1150 load as we used a non-portable Linux specific struct field
1151 (fixes bug #70, patch by Ronald Baljeu)
1152 - fixed endless loop which occured when loading an instrument editor
1153 plugin DLL on Windows systems failed
1154 - fixed memory leaks that occurred when liblinuxsampler was unloaded
1155 - optimized the SynchronizedConfig class so it doesn't wait
1156 unnecessarily long after an update
1157 - added support for notifying instrument editors on note-on / note-off
1158 events (e.g. to highlight the pressed keys on the virtual keyboard
1159 of gigedit)
1160 - added support for triggering notes by instrument editors (see above)
1161 - be verbose on DLL load errors (on Linux)
1162 - fixed di-harmonic triangle LFO implementation (this LFO implementation
1163 is only used by very few systems, most pick the int math
1164 implementation, which is usually faster)
1165 - fixes for audio drivers with varying buffer sizes
1166 - experimental support for running LinuxSampler as a DSSI, LV2 and
1167 VST plugin
1168 - notification events for stream/voice count statistics are now sent
1169 only when there are actual changes
1170 - added memory ordering constraints to improve stability on
1171 multi-core and multi-cpu systems
1172 - maximum voices and disk streams can now be altered at runtime
1173 - fixed CPU feature detection on x86_64 (maybe fixes #108)
1174 - automatic stacktrace mechanism is now turned off by default and can
1175 be switched on by command line option "--stacktrace" (the automatic
1176 stacktrace mechanism seems to be broken on most systems at the moment)
1177 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
1178 a pointer to the launched InstrumentEditor object
1179 - added optional 3rd party user data parameter for following
1180 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
1181 InstrumentEditor::Launch(),
1182 InstrumentManager::LaunchInstrumentEditor()
1183 - theoretical fix: made SynchronizedConfig follow C++0x memory
1184 model more strictly
1185 - fixes for using large audio device buffers
1186 - Windows: add the installation directory to the DLL search path
1187 when loading an editor plugin (solves problems with VST and
1188 gigedit on systems with other GTK versions installed)
1189 - updated linuxsampler man page
1190
1191 * audio driver:
1192 - removed the nonsense audio channel constraint (which was hard coded to
1193 max. 100 audio channels) for most audio drivers
1194 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
1195 opposed to the LSCP specs
1196 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
1197 reflected the wrong value
1198 - fixed a memory management bug in ASIO driver
1199 - Makefile fix: JACK_CFLAGS wasn't used
1200 - JACK: use jack_client_open instead of the deprecated
1201 jack_client_new
1202 - added (experimental) CoreAudio driver
1203 - applied old fixes to the ASIO driver that were included in the
1204 previous binary release but accidentally never committed to CVS
1205 (fixes #117)
1206 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
1207 win64)
1208 - VST: added support for sample rate and buffer size changes
1209 - VST: close editor (Fantasia) when the VST is removed
1210 - VST: avoid opening Fantasia more than once for each VST instance
1211 - VST: export main function as "main" on Linux too (fix for
1212 energyXT)
1213 - VST: changed number of output channels from one stereo to 16
1214 stereo
1215 - added channel routing, fxsends and midi maps to the settings
1216 stored in the plugin state
1217 - performance optimization of AudioChannel::MixTo() and
1218 AudioChannel::CopyTo() methods using GCC vector exensions
1219 (if available)
1220 - ASIO fixes: avoid initializing the device twice, avoid throwing
1221 exception when getting parameters from a disconnected device
1222
1223 * MIDI driver:
1224 - added JACK MIDI driver
1225 - dispatch bank select as ordinary CC as well, the user might seriously
1226 want to (mis)use it for some purpose ("fixed" in all current MIDI
1227 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
1228 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
1229 CoreMidi or AU
1230 - fixed mingw-w64 compilation error in MME driver
1231 - made program change handling in MIDI thread real-time safe by
1232 moving the logic to a non-RT thread
1233 - fixed minor memory leak in ALSA driver
1234
1235 * instruments database:
1236 - avoid time consuming samples scanning when adding instruments
1237 to the instruments database
1238 - added support for handling lost files in the instruments database
1239 - Implemented option for adding instruments in separate directories
1240 in the instruments database
1241 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
1242 - work-around for missing fnmatch function on Windows to make
1243 instrument database compilable
1244 - added instrument database support on Windows
1245 works with both standalone mode and VST plugin.
1246 the instruments DB file is located in
1247 %USERPROFILE%\.linuxsampler\instruments.db which allows different
1248 databases for each windows user
1249 if no DB is present it automatically creates the .linuxsampler subdir
1250 and then creates an empty DB
1251 - fixed recursive import, which was broken on Windows
1252
1253 * Gigasampler format engine:
1254 - fixed a memory leak that could happen when a channel was deleted
1255 while notes were playing
1256 - made it possible to load an instrument even if the audio thread
1257 isn't running
1258 - added partial support for the "Controller Triggered" MIDI rule,
1259 enough for piano gigs with pedal noise samples
1260 - minor fix: only mark FX sends as being modified if really the
1261 respective FX send MIDI controller was used
1262 - added support for GM global device volume SysEx message
1263 (can be selected at compile time to either apply globally to the
1264 whole sampler [default] or only to the sampler channels that are
1265 connected to the respective MIDI input port the SysEx message arrived
1266 on)
1267 - bugfix: notes triggered at position 0 in the audio buffer were
1268 sometimes wrongly killed in the same buffer, causing no sound to
1269 be played
1270 - added support for chromatic / drumkit mode Roland GS Sysex message
1271 which is usally used to switch a part between chromatic sounds and
1272 drumkit sounds (as opposed to their common default setting of MIDI
1273 part 10 being a drumkit part and all other ones chromatic parts), in
1274 LS however one can switch between the first 16 MIDI instrument maps
1275 defined for the sampler
1276 - made it possible to create multiple sample channels even if the
1277 audio thread isn't running
1278 - fixed crash when removing channel with active voices (#116)
1279 - bugfix: on sample reference changes (instrument editor), only
1280 un-cache the respective sample if it's really not used by any
1281 sampler engine anymore
1282 - re-cache samples in case they were changed by an instrument editor,
1283 e.g. when a sample was added while playing (#82)
1284 - fixed hanging notes which occured when note-off event had the exact
1285 same time stamp as the voice's note-on event and occured both in the
1286 same audio fragment cycle (fixes bug #112)
1287 - added support for the "fine tune" and "pitch bend range"
1288 instrument-level gig parameters
1289 - fixed minor artifacts in pitch bend handling
1290 - added support for GS Reset SysEx message
1291 - allow gig files to use unlimited downward pitch shifting
1292 - added a limit check for upward pitch shifting
1293 - bugfix: sometimes, when playing a note twice fast, the second
1294 note was silent
1295 - fixed crash happening when a pitch bend event arrived at the
1296 same time a new instrument was loading
1297
1298 * LSCP server:
1299 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
1300 react on MIDI data arriving on certain sampler channels (so far only
1301 Note-On and Note-Off events are sent via this LSCP event)
1302 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1303 react on MIDI data arriving on certain MIDI input devices (so far only
1304 Note-On and Note-Off events are sent via this LSCP event)
1305 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
1306 SET DB_INSTRUMENT FILE_PATH
1307 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
1308 frontends to send MIDI messages to specific sampler channel
1309 - added two additional fields to GET FILE INSTRUMENT INFO command -
1310 KEY_BINDINGS and KEYSWITCH_BINDINGS
1311 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1312 was incorrect
1313 - Optimized the retrieval of the MIDI instrument mappings
1314 - added new LSCP command "SET VOICES" to globally alter the maximum
1315 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1316 be triggered respectively
1317 - added new LSCP command "SET STREAMS" to globally alter the maximum
1318 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1319 which will be triggered respectively
1320 - bugfix: retry if "select" returns EINTR (this fixes a crash when
1321 a gigedit file dialog is opened)
1322 - close all connections when LSCPServer is deleted
1323 - hard close of all sockets on exit
1324 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
1325 driver
1326
1327 * Bug fixes:
1328 - fixed a crash which occurs when removing a sampler channel waiting
1329 to start instrument loading after another channel
1330 - fixed a crash which occurs when removing a sampler channel with
1331 instrument loading in progress (bug #113)
1332 - fixed termination caused by uncaught exception when adding MIDI
1333 instrument with PERSISTENT load mode
1334 - fixed possible iterator invalidations when resetting the sampler
1335 - fixed memory leaks when issuing the following LSCP commands:
1336 GET AUDIO_OUTPUT_DRIVER INFO
1337 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
1338 GET MIDI_INPUT_DRIVER INFO
1339 GET MIDI_INPUT_DRIVER_PARAMETER INFO
1340 - fixed possible compilation error when sqlite is not present
1341 - fixed orphaned pointers when setting maximum voices limit (bug #118)
1342 - fixed crash when changing the audio output device of a sampler
1343 channel with loaded instrument and start playing notes
1344 - fixed endless loop in Engine::SuspendAll() (bug #120)
1345 - fixed a low-level atomic load function that was broken on 64-bit
1346 PowerPC, which probably could cause crashes on that platform
1347 - fixed a memory management error which could cause a crash when a
1348 plugin was unloaded
1349 - bugfix: two private structs had the same name, which could cause
1350 problems if the linker chose the wrong constructor
1351 - fixed low-level ConditionServer usage bug that caused lockups on
1352 Windows
1353
1354
1355 Version 0.5.1 (6 December 2007)
1356
1357 * packaging changes:
1358 - added autoconf checks for pthread library
1359 - added autoconf check for pthread bug found on certain NPTL-enabled
1360 glibc versions (see Gentoo bug report #194076)
1361 - added autoconf checks for MS Windows
1362
1363 * general changes:
1364 - bugfix: the thread used by an editor plugin didn't die when the
1365 editor closed
1366 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1367 out all the space. operator--() did not apply size_mask after
1368 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1369 order to avoid problems with the _NonVolatileReader functions.
1370 - bugfix: Stream.h: added a missing divide by BytesPerSample in
1371 GetWriteSpace(). Since this function is currently only used in
1372 the stream's qsort() compare function, it didn't trigger any
1373 bugs.
1374 - Resampler.h, Synthesizer.h: cubic interpolation now works in
1375 24bit mode too. Faster method to read 24bit words on little
1376 endian machines (x86): replaced 3 byte reads + shifts with a 1
1377 unaligned 32bit read and shift
1378 - experimental support for MS Windows (MIDI input via MME, AUDIO
1379 output via ASIO)
1380 - made handling of SIGINT signal (Ctrl-C) a bit more robust
1381 - support for monitoring the total number of active disk streams
1382 (new LSCP commands: GET TOTAL_STREAM_COUNT,
1383 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1384
1385 * AUDIO driver:
1386 - added Windows ASIO low latency audio driver
1387
1388 * MIDI driver:
1389 - added MME Windows MIDI driver
1390
1391 * LSCP server:
1392 - added support for Windows style path / filenames, however with
1393 forward slash path separators instead of backslash
1394 (i.e. "C:/foo/bar.gig")
1395 - allow naughty liblscp to send non-string device parameters within
1396 apostrophes as well
1397 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1398 "LIST FILE INSTRUMENTS <file>" and
1399 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1400 about an arbitrary instrument file on the system where the sampler is
1401 running on
1402
1403 Version 0.5.0 (15 October 2007)
1404
1405 * packaging changes:
1406 - config.h is not going to be installed along with liblinuxsampler's
1407 API header files anymore
1408 - only the API relevant header (and source) files will be exported to
1409 the Doxygen API documentation (explicitly listed in Doxyfile.in)
1410 - added completely new XCode project files for Mac OSX which is now
1411 capable to execute our autoconf environment, thus no need anymore
1412 to maintain the compile time configuration file (osx/version.h) for
1413 OSX manually (patch by Toshi Nagata)
1414 - fixed buggy boolean --enable-foo / --disable-foo configure script
1415 parameters
1416 - global.h now only covers global definitions that are needed for the
1417 C++ API header files, all implementation internal global definitions
1418 are now in global_private.h
1419 - atomic.h is not exposed to the C++ API anymore
1420 - no need to include config.h anymore for using LS's API header files
1421 - fixed warnings in API doc generation
1422
1423 * general changes:
1424 - replaced the old, confusing MIDI program change mechanism by a
1425 flexible MIDI instrument mapper which allows to map arbitrary
1426 (MIDI bank, MIDI program) pairs with arbitrary
1427 (engine type, instrument file, file index) triplets which will be
1428 loaded on the respective channel when such MIDI program change
1429 messages arrive, beside that, each entry allows to define a life-time
1430 strategy for the instrument, so the user can define whether the
1431 instrument should i.e. be permanently loaded (to be able to switch
1432 quickly among sounds) or i.e. loaded just on demand when the
1433 respective program change arrives (to safe RAM space), as well as a
1434 global volume factor for each entry, so the user can adjust the volume
1435 dynamic of his mapped instrument collection without having to modify
1436 the instrument files, also one can manage arbitrary amount of such
1437 MIDI instrument maps and assign each sampler channel individually
1438 a certain map, so that i.e. separation of normal instruments and
1439 drumkits is possible
1440 - new notification events for tracking changes to audio/MIDI devices,
1441 MIDI instrument maps, MIDI instruments, FX sends, global volume.
1442 - sampler was limited to load max. 200 instruments in the background
1443 due to a constant size RingBuffer FIFO which is now replaced by a
1444 dynamic (unlimited) size std::list FIFO
1445 - added FX sends, these allow to route audio signals to arbitrary audio
1446 output channels for being processed by external effect processors
1447 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1448 controllers
1449 - global (sampler wide) volume can now be controlled at runtime
1450 - Implemented new, improved notification system
1451 - fixed compilation errors regarding OSX
1452 (patch by Toshi Nagata)
1453 - implemented instruments database
1454 - added support for escape sequences to the instruments database
1455 - added highly experimental support for on-the-fly instrument editing
1456 within the sampler's process (by using instrument editor plugins),
1457 you'll notice the new "Registered instrument editors:" message on
1458 startup, added a new LSCP command:
1459 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1460 to spawn a matching instrument editor for the instrument on the
1461 given sampler channel, the plugin path can be overridden at compile
1462 time with ./configure --enable-plugin-dir=/some/dir
1463 - added experimental code for synchronizing instrument editors hosted
1464 in the sampler's process to safely edit instruments while playing
1465 without a crash (hopefully) by either suspending single regions
1466 wherever possible or if unavoidable whole engine(s)
1467 - fixed several issues in fundamental "Thread" class: set scheduling
1468 policy and priority on thread level, set a minimum stack size for
1469 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1470 threads simply inherited properties of starting thread instead of
1471 setting their own policy and priority
1472 - minor fix in our automatic stack trace mechanism on crashes, the
1473 main process did not wait for the stack trace process to finish
1474 its output
1475 - fixed some minor memory leaks
1476 - reenabled assembly features support, at the moment only for
1477 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1478 - minor assembly fix in x86 features detection (don't use the PIC
1479 register, to avoid relocations in the text segment at runtime)
1480 - POSIX callback functions of Thread.h are hidden
1481
1482 * MIDI driver:
1483 - dispatch bank select (MSB and LSB) messages
1484
1485 * audio driver:
1486 - the ALSA audio output driver parameters now reflect the correct
1487 parameter value ranges for the respective selected sound card
1488 (patch by Till Wimmer, a bit fixed and extended)
1489
1490 * Gigasampler format engine:
1491 - if a filter is used and EG2 finishes before EG1, let the voice
1492 die when EG2 has finished (this fixes a problem with clicks and
1493 voice starvation for some gigs)
1494 - playback is no longer disabled during instrument loading
1495 - all notes playing on a channel that changes its instrument keep
1496 playing with the old instrument until they get a note off
1497 command
1498 - EG fix: a release value of zero could cause noises or crash
1499 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1500 - EG fine tuning: when attack is zero the EG starts at a level
1501 above max sustain level, which means that there is a decay phase
1502 even if sustain is 100%
1503 - more EG fixes: the level could sometimes go below zero and cause
1504 noises or crashes
1505 - minor fix of EGDecay (patch by Toshi Nagata)
1506 - fixed compiler error when --enable-override-filter-type was
1507 supplied to the configure script (fixes #46)
1508 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1509 instead of a fix value
1510 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1511 127 (solo mode) only kill voices if the respective mode really
1512 changed
1513
1514 * LSCP server:
1515 - fixed compile time error for old Bison versions
1516 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1517 - parser now supports extended ASCII character set
1518 (up to ASCII code 255, i.e. includes now umlauts and accents)
1519 - filename arguments in LSCP commands now allow to use escape
1520 sequences, that is directly literal as one of: \', \", \\, \n, \r,
1521 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1522 code value like \xf2) (fixes bug #24)
1523 - the following LSCP commands now also support escape sequences for at
1524 least one of their text-based parameters (i.e. name, description):
1525 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1526 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1527 "SET DB_INSTRUMENT_DIRECTORY NAME",
1528 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1529 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1530 "FIND DB_INSTRUMENT_DIRECTORIES"
1531 - returns verbose syntax errors (line and column where syntax error
1532 occured, the unexpected character and the actually expected, possible
1533 character(s), the latter only if less than 5 possibilities)
1534 - made sure that LSCP syntax is not affected by gigedit locale
1535 settings
1536 - bugfix regarding strings parameter lists: all comma separated lists
1537 of strings were treated as being one string containing commas
1538 (fixes #57)
1539
1540 * Bug fixes:
1541 - fixed crash occurring on certain LSCP scripts (Bug 39)
1542 - another thread safety fix for lscp "load engine" and "set
1543 channel audio output device"
1544 - fixed a crash which occurs when reassigning the same engine
1545 on a sampler channel with connected MIDI device
1546 - fixed a crash which occurs when changing the number of ports of a MIDI
1547 device connected to a sampler channel to number less then or equal
1548 to the index of the port to which the sampler channel is connected.
1549 - The previous bindings were not been disconnected when altering
1550 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1551 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1552 - The active stream/voice count statistic was incorrect.
1553 - notification events were not been sent for some sampler
1554 channel changes
1555 - added default min and max values to restrict the number of allowed
1556 audio output channels and MIDI input ports
1557 - the connection to the PCM interface is now closed when destroying
1558 an audio output device
1559 - files with slash in their path or filename could not be loaded
1560
1561 * test cases:
1562 - updated and fixed (haven't been touched in a while)
1563
1564 Version 0.4.0 (24 November 2006)
1565
1566 * packaging changes:
1567 - changed deprecated copyright attribute to license; added ldconfig
1568 to post-(un)install steps; added devel package for liblinuxsampler;
1569 to linuxsampler.spec (RPM)
1570 - install necessary development header files for allowing 3rd party
1571 applications to link against liblinuxsampler
1572 - liblinuxsampler's API documentation can be generated with 'make docs'
1573 (Doxygen required)
1574 - added benchmark to automatically detect the best triangle LFO
1575 implementation (currently either an integer math solution or a
1576 di-harmonic approximation), automatic detection can be overriden
1577 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1578 configure script argument though (mandatory for cross-compilation)
1579 - do not automatically pick optimized gcc flags if the user already
1580 provided some on his own (as CXXFLAGS)
1581 - added compile time option to disable processing of All-Notes-Off MIDI
1582 messages
1583 - added compile time options to allow disabling the various audio and
1584 MIDI drivers
1585 - fixed automatic GCC CPU switch detection on PPC
1586 (patch by Ebrahim Mayat)
1587
1588 * Gigasampler format engine:
1589 - extensive synthesis optimization
1590 (reimplementation of EGs and LFO(s), removed synthesis parameter
1591 prerendering and the synthesis parameter matrix in general, splitting
1592 each audio fragment into subfragments now where each subfragment uses
1593 constant pitch and filter coefficients. The volume coefficient is
1594 linearly interpolated inside a subfragment, unless
1595 --disable-interpolate-volume is set.)
1596 - fine tuning of the EG modulation parameters
1597 - improved filter cutoff calculation by adding support for the
1598 following gig parameters: Cutoff freq (used when no cutoff
1599 controller is defined), Control invert, Minimum cutoff, Velocity
1600 curve and Velocity range. The keyboard tracking now scales
1601 cutoff frequency instead of resonance.
1602 - added support for gig parameter Resonance.
1603 - fixed bug in sysex handling (patch by Juan Linietsky)
1604 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1605 which can be overridden with --enable-global-attenuation
1606 - EG fixes: made the length of "attack hold" stage more
1607 accurate. Release stage can now start before attack stage
1608 ends. Cancel release didn't work when sustain was zero. Attack
1609 time now has a minimal value to prevent clicks.
1610 - fixed pitch changes larger than one octave
1611 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1612 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1613 all modes can be altered via standard GM messages, that is CC5 for
1614 altering portamento time, CC65 for enabling / disabling portamento
1615 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1616 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1617 parameter) and crossfade
1618 - added support for the "attenuation controller threshold" gig
1619 parameter
1620 - added smoothing of volume changes caused by control change
1621 messages
1622 - sample loop parameters are now taken from the DimensionRegion
1623 instead of the wave chunk
1624 - fixed keyswitching for v3 gigs with a number of keyswitch splits
1625 not equal to a power of two
1626 - reimplementation of the filter algorithm. The new filter is more
1627 accurate and supports all gig filter types, including bandreject
1628 and lowpass turbo.
1629 - real support for 24 bit samples - samples are not truncated to
1630 16 bits anymore
1631 - support for aftertouch (channel pressure, not polyphonic
1632 aftertouch)
1633 - LFO1 behaviour fixed (dampening from max volume instead of
1634 amplifying from 0)
1635
1636 * LSCP server:
1637 - fixed application exit on broken pipe error (fixes bug #20)
1638 - fixed the notification messages delay due to lack of
1639 network activity (fixes bug #26)
1640 - fixed parser bug which occured on space(s) within device parameters
1641 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1642
1643 * audio driver:
1644 - added aRts audio output driver (by no means RT safe)
1645
1646 * MIDI driver:
1647 - fixed legacy sysex code which caused dispatching of MIDI SysEx
1648 messages several times instead of once
1649 - API extension for MIDI drivers which already supply exact time stamps
1650 for events (i.e. for offline rendering based MIDI drivers)
1651 - added checks for bad MIDI data
1652
1653 * linuxsampler application:
1654 - show available sampler engine types on startup
1655
1656 * general changes:
1657 - support for muting sampler channels and solo mode of the same, two new
1658 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1659 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1660 introduced for this, the behavior is the same like on a mixer console
1661 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1662 --enable-process-muted-channels which can be used to enable the
1663 processing of muted channels.
1664 - support for sostenuto pedal
1665 - support for monitoring the total number of active voices
1666 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1667 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1668 - fixed some memory management errors
1669 - fixed some concurrency problems that could lead to crashes when
1670 LSCP commands were executed
1671 - fixed crash when instrument loading failed previously on the same
1672 sampler channel (fixes bug #36)
1673
1674 Version 0.3.3 (15 July 2005)
1675
1676 * packaging changes:
1677 - fixed compilation with gcc 4.0
1678
1679 * Gigasampler format engine:
1680 - LFO preprocessing was performed even though the respective LFO was
1681 disabled by the instrument patch (minor efficiency fix)
1682 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1683 for volume ramp downs in the same fragment (needed for current voice
1684 stealing implementation) then simply inform the user with a warning
1685 about possible click sounds and reduce the volume ramp down
1686 appropriately instead of cancelling the audio device connection
1687
1688 Version 0.3.2 (24 June 2005)
1689
1690 * packaging changes:
1691 - updated autotools build files to compile on OS X
1692 (conditional compilation of CoreMIDI and MidiShare drivers)
1693 - hand-crafted assembly optimization code can be disabled with
1694 './configure --disable-asm' (definitely not recommended)
1695 - fixed 'make dist' rule to include all necessary files
1696 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1697 (due to 'dist-bzip2' automake option)
1698
1699 * Gigasampler format engine:
1700 - support for the gig parameters for "release velocity response" curves
1701 - fine tuning of the EGADSR envelope
1702 - volume of release triggered samples now depends on note-on velocity,
1703 note length and gig parameter "release trigger decay" instead of
1704 note-off velocity.
1705 - revised voice stealing
1706 (fixes crash and endless loop caused by voice stealing)
1707 - don't reset scale tuning on instrument or audio output device change
1708 - handle key group conflicts right at the beginning of each fragment
1709 instead of when the respective voice is actually launched
1710 (fixes undefined behavior if stolen voices belonged to a key group -
1711 this case was followed by a "killed voice survived" error message)
1712 - fixed minor issue with null/silence samples
1713 (those stole voices even though they don't need a voice at all which
1714 resulted in "voice stealing didn't work out" messages)
1715 - don't reset volume, pan, pitch and MIDI controller values on
1716 instrument or audio output device change
1717
1718 * LSCP server:
1719 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1720 - fixed LSCP event "CHANNEL_INFO" notification
1721 (e.g. did not notify on volume changes or MIDI program change events)
1722
1723 * linuxsampler application:
1724 - added command line parameters --lscp-addr and --lscp-port to override
1725 default IP address and port of LSCP server
1726
1727 Version 0.3.1 (24 May 2005)
1728
1729 * initial release
