File size: 94781 byte(s)
* Event:Init(): memset() entire Event::Param union to zero instead of trying
  to do that for its individual members; the latter became error prone due
  to the union's growing complexity meanwhile.

* Bumped version (2.1.1.svn27).

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
35 * Real-time instrument scripts:
36 - Added method ScriptVM::setExitResultEnabled() which allows to
37 explicitly enable the built-in exit() function to optionally accept
38 one function argument; the value of the passed exit() function
39 argument will then become available by calling
40 VMExecContext::exitResult() after script execution.
41 - 64 bit support for NKSP integer scripts variables (declare $foo).
42 - Variable names, function names and preprocessor condition names must start
43 with a regular character (a-z or A-Z); starting them with a digit or
44 underscore is not allowed.
45 - NKSP parser fix: equal comparison operator "=" and not equal comparison
46 operator "#" must only accept integer operands.
47 - NKSP language: Implemented support for standard units like Hertz, seconds,
48 Bel including support for metric unit prefixes; so one can now e.g.
49 conveniently use numbers in scripts like "5us" meaning "5 microseconds",
50 or e.g. "12kHz" meaning "12 kilo Hertz", or e.g. "-14mdB" meaning
51 "minus 14 Millidecibel", or e.g. "28c" meaning "28 cents" (for tuning).
52 - NKSP language: Introduced "final" operator "!" which is specifically
53 intended for synthesis parameter values to denote that the synthesis
54 parameter value is intended to be the "final" value for that synthesis
55 parameter that should explicitly be used by the engine and thus causing
56 the sampler engine to ignore all other modulation sources for the same
57 synthesis parameter (like e.g. LFO, EG); by simply prefixing a value,
58 variable or formula with this new "!" operator the expression is marked as
59 being "final".
60 - NKSP script editor API: Added support for detecting standard unit tokens
61 and their potential metric prefix token.
62 - NKSP language: Added support for NKSP real number literals and
63 arithmetic operations on them (e.g. "(3.9 + 2.9) / 12.3 - 42.0").
64 - NKSP language: Added support for NKSP real number (floating point) script
65 variables (declare ~foo).
66 - NKSP language: Added support for NKSP real number (floating point) array
67 script variables (declare ?foo[]).
68 - Built-in script function "message()" accepts now real number argument as
69 well.
70 - Added built-in script function "real_to_int()" and its short hand form
71 "int()" for casting from real number to integer in NKSP scripts.
72 - Added built-in script function "int_to_real()" and its short hand form
73 "real()" for casting from integer to real number in NKSP scripts.
74 - Allow built-in exit() function to potentially accept real number type
75 argument as well.
76 - Built-in script functions may have a different return type depending on
77 the arguments passed to the function.
78 - Built-in script function "abs()" optionally accepts and returns real
79 number.
80 - Built-in script functions "min()" and "max()" optionally accept real
81 number arguments and return real number as result in that case.
82 - NKSP VM API: Allow units and 'final'ness to be returned as result from
83 built-in functions (added methods VMFunction::returnUnitType() and
84 VMFunction::returnsFinal() for that purpose which must be implemented by
85 built-in function implementations).
86 - NKSP language: Allow metric unit prefixes of numeric scalar and array
87 variables to be changed freely at runtime (unlike unit types like Hz etc.
88 which are still sticky, parse-time features of variables which cannot be
89 changed at runtime for the intentional sake of determinism).
90 - NKSP language: 'final' values are prohibited for array variables for now
91 (attempt causes a parsers error).
92 - NKSP language: expressions with unit types (e.g. Hz) are prohibited for
93 conditions of runtime control structures like if(), while(), select()
94 (attempt causes a parser error).
95 - NKSP VM API: Allow built-in functions to perform their own, individual
96 parse time checks of arguments going to be passed to the function at
97 runtime (added method VMFunction::checkArgs() for that purpose).
98 - NKSP language: raise parser warning if only one operand of binary
99 operators (like logical 'or' comparison) contain a 'final' value (because
100 it would always yield in a 'final' result in such cases).
101 - NKSP language: Allow comparison (=, #, <, >, <=, >=) of values with
102 different metric unit prefixes, which will behave as expected (e.g.
103 result of expression '1000us < 2ms' is true).
104 - NKSP language: Allow adding values with different metric unit prefixes
105 (e.g. result of expression '100Hz + 5kHz' is '5100Hz').
106 - NKSP language: Allow subtracting values with different metric unit
107 prefixes (e.g. result of expression '1ms - 20us' is '980us').
108 - NKSP language: Allow multiplying with any metric unit prefixes
109 (e.g. result of expression '2k * 3ms' is '6s'), however multiplications
110 with unit types on both sides (e.g. '2s * 2s') is still prohibited since
111 we don't have any considerable practical use for a term like '4s^2'
112 (hence any attempt multiplying two unit types still causes parser error).
113 - NKSP language: Allow dividing by any metric unit prefixes and allow
114 division of same unit type on both sides (e.g. expression '8kHz / 1000Hz'
115 yields in unit free result '8'). So this is now a way to cast units away
116 e.g. for passing the result to other expressions, certain function calls
117 or variables which are not accepting any units (or that specific unit).
118 - NKSP language: integer arrays and real number arrays can now be converted
119 to strings (e.g. for dumping their content with message() calls for
120 script debugging purposes).
121 - NKSP language: expressions and variables with units are now correctly
122 casted to strings (e.g. with message() calls).
123 - NKSP language: comparing real numbers for equalness (e.g. '~foo = 3.1') or
124 unequalness (e.g. '~foo # 3.1') is now less strict and takes the expected
125 floating point tolerances into account.
126 - NKSP VM API: Added methods VMScalarNumberExpr::evalCastInt() and
127 VMScalarNumberExpr::evalCastReal().
128 - NKSP VM API: Added base class 'VMNumberArrayExpr' for classes
129 'VMIntArrayExpr' and 'VMRealArrayExpr'.
130 - NKSP VM API: replaced all unitPrefix() (parse time) methods by
131 unitFactor() (runtime) methods.
132 - Built-in function "exit()" supports now returning units and 'final'ness
133 for test cases.
134 - The following built-in functions support now units as well: "abs()",
135 "random()", "inc()", "dec()", "in_range()", "min()", "max()",
136 "real_to_int()", "int()", "int_to_real()" and "real()".
137 - Built-in functions "array_equal()", "search()" and "sort()" support now
138 real number arrays (correctly) as well.
139 - Added individual parse time checks of arguments to be passed to built-in
140 functions "random()", "inc()", "dec()", "in_range()", "min()", "max()",
141 "array_equal()" and "search()" specific for their individual purposes.
142 - NKSP VM refactoring: Renamed all methods, functions and classes matching
143 pattern *ScalarNumber* to simply *Number* (that is i.e. classes
144 VMScalarNumberExpr -> VMNumberExpr, ScalarNumberExpr -> NumberExpr,
145 ScalarNumberVariable -> NumberVariable, ScalarNumberBinaryOp ->
146 NumberBinaryOp, VMScalarNumberResultFunction -> VMNumberResultFunction,
147 method VMExpr::asScalarNumberExpr() -> VMExpr::asNumber(), function
148 isScalarNumber() -> isNumber()).
149 - NKSP VM API: Added 4 overridden methods to class VMNumberExpr:
150 evalCastInt(MetricPrefix_t), evalCastInt(MetricPrefix_t,MetricPrefix_t),
151 evalCastReal(MetricPrefix_t), evalCastReal(MetricPrefix_t,MetricPrefix_t)
152 as convenient methods for automatically converting values to expected
153 metric value basis.
154 - Built-in function "wait()" accepts now both integers and real numbers as
155 argument.
156 - NKSP VM API cleanup: Get rid of legacy method
157 VMFunction::argType(vmint iArg) which was already superseded by its new
158 replacement VMFunction::acceptsArgType(vmint iArg, ExprType_t type).
159 - NKSP parser: if wrong argument type was passed to a built-in function and
160 that built-in function accepts more than one data type for the argument,
161 then show all supported data types as parser error message.
162 - Built-in function "play_note()" accepts now real numbers and seconds as
163 unit type as well for its 3rd and 4th function arguments.
164 - The following built-in functions accept now real numbers as well for their
165 2nd function argument: "change_vol()", "change_tune()", "change_cutoff()",
166 "change_attack()", "change_decay()", "change_release()",
167 "change_sustain()", "change_cutoff_attack()", "change_cutoff_decay()",
168 "change_cutoff_sustain()", "change_cutoff_release()",
169 "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
170 "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
171 "change_pan_time()", "fade_in()", "fade_out()", "change_play_pos()".
172 - Fixed built-in function "change_play_pos()" not having accepted metric
173 prefixes at all.
174 - Fixed the following built-in functions having misinterpreted values given
175 with unit type (for their 2nd argument) as if they were relative values
176 (that is as if they were passed without a unit type): "change_attack()",
177 "change_decay()", "change_release()", "change_cutoff_attack()",
178 "change_cutoff_decay()", "change_cutoff_release()".
179 - Fixed the following built-in functions having applied completely wrong
180 'final' values: "change_sustain()", "change_cutoff_sustain()" (since the
181 respective EGs being their modulation sink assume uint data type with
182 value range 0..1000 instead of 0.0..1.0.
183 - Added individual parse-time checks of function arguments for the following
184 built-in functions: "play_note()", "note_off()", "set_event_mark()",
185 "delete_event_mark()", "by_marks()", "change_cutoff()", "change_attack()",
186 "change_decay()", "change_release()", "change_cutoff_attack()",
187 "change_cutoff_decay()", "change_cutoff_release()",
188 "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
189 "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()" and
190 "change_pan_time()".
191 - Don't abort function call if unit type was used and at the same time
192 'final' operator was omitted for the primary value argument of the
193 following built-in functions: "change_cutoff()", "change_attack()",
194 "change_decay()", "change_release()", "change_cutoff_attack()",
195 "change_cutoff_decay()", "change_cutoff_release()",
196 "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
197 "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
198 "change_pan_time()", instead imply 'final'ness at runtime and raise an
199 appropriate parser warning at parse time.
200 - Added built-in real number functions "round()", "ceil()", "floor()",
201 "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()", "sin()",
202 "cos()", "tan()", "asin()", "acos()", "atan()".
203 - Added built-in script real number constant "~NI_MATH_PI".
204 - Added built-in script real number constant "~NI_MATH_E".
205 - NKSP language: Allow unary '+' operator.
206 - Added built-in script functions "msb()" and "lsb()".
207
208 * test cases:
209 - Fixed compiler errors in test cases.
210 - Updated README for how to compile & run test cases.
211 - Updated test case
212 MutexTest::testDoubleLockStillBlocksConcurrentThread() to latest
213 expected behaviour of the Mutex class implementation (recursive
214 mutex type).
215 - Added test cases for NKSP core language aspects and core built-in
216 functions.
217 - Fixed thread tests segfaulting on Linux.
218 - NKSP: Added real number test cases for built-in functions exit(),
219 int_to_real(), real(), real_to_int() and int(), as well as for the
220 plus, minus and negate language operators.
221 - Added massive amount of NKSP test cases for standard measuring units and
222 'final' operator usage cases.
223 - Added NKSP test cases for (floating point tolerance aware) real number
224 equalness / unequalness comparison.
225 - Added NKSP int array and real array tests for value assignment and
226 initialization of arrays.
227 - Added NKSP test cases for built-in functions "round()", "ceil()",
228 "floor()", "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()",
229 "sin()", "cos()", "tan()", "asin()", "acos()", "atan()".
230 - Added NKSP test cases for unary '+' operator.
231
232 * GigaStudio/Gigasampler format engine:
233 - LFOTriangleIntMath and LFOTriangleIntAbsMath: Fixed FlipPhase=true
234 behaviour for start_level_mid.
235 - Changed LFO start levels: LFO1 and LFO2 both to mid, LFO3 to max. start
236 level (see discussion "GigaStudio LFO compatibility" on mailing list
237 from 2019-09-26 for details).
238 - Changed default wave form for all 3 LFOs to sine (instead of triangle;
239 see discussion "GigaStudio LFO compatibility" on mailing list from
240 2019-09-26 for details).
241 - Format extension: Added support for different LFO wave forms (currently
242 either sine [default], triangle, saw or square).
243 - Format extension: Added support for LFO phase displacement (0��..360��).
244 - Format extension: Added support for flipping LFO polarity on LFO 3
245 (in the original gig format this was only available for LFO 1 and LFO 2).
246 - Format extension: Support for additional filter types:
247 lowpass 1/2/4/6-pole, highpass 1/2/4/6-pole, bandpass 2-pole,
248 bandreject 2-pole.
249
250 * SFZ format engine:
251 - Fixed support for regions with loccN/hiccN conditions on more than one
252 MIDI controller.
253
254 * Benchmarks:
255 - Fixed benchmarks/triang.cpp falsely having favoured "int math abs"
256 algorithm (since result of 2nd run was not accumulated).
257 - Added benchmark for saw wave (benchmarks/saw.cpp).
258 - Added benchmark for sine wave (benchmarks/sine.cpp).
259 - Added benchmark for square wave (benchmarks/square.cpp).
260 - Increased amount of benchmarks runs by factor 6 to achieve benchmark times
261 which are large enough on modern systems.
262
263 Version 2.1.1 (27 Jul 2019)
264
265 * Real-time instrument scripts:
266 - Fixed behavior of built-in NKSP functions change_sustain(),
267 change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain()
268 and change_cutoff_release().
269
270 * general changes:
271 - Only play release trigger samples on sustain pedal up if this behaviour
272 was explicitly requested by the instrument (otherwise only on note-off).
273 - Fixed compiler warnings.
274 - Fixed compilation error when cross-compiling to Mac.
275 - FX Sends: Provide more useful error messages on routing problems
276 (see bug #169).
277 - LSCP doc: Be more clear describing the two distinct approaches
278 of using external vs. internal effects (see bug #169).
279 - "optional" class: Fixed comparison operators.
280
281 * Gigasampler/GigaStudio format engine:
282 - Format extension: If requested by instrument then don't play release
283 trigger sample on note-off events.
284
285 * SFZ format engine:
286 - Fixed memory leak when releasing samples
287 (fixes bug #307, patch by Jacek Roszkowski)
288 - Fixed potential crash when a sample is shared by more than one region
289 (fixes bug #308, patch by Jacek Roszkowski).
290 - Opcode 'sample': Added support for built-in sample '*silence'
291 (fixes bug #310, patch by Jacek Roszkowski).
292
293 Version 2.1.0 (25 Nov 2017)
294
295 * SFZ format engine:
296 - added support for <global>, <master> and #define (patch by Alby M)
297 - Removed code duplication in SFZ file loading code.
298 - Added support for sfz extension opcode 'script' which may be used to
299 load real-time instrument script file (NKSP script language).
300 - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
301 - Fixed unintended volume fade-in of voices under certain conditions.
302 - sfz parser: allow missing space between header and opcode
303
304 * Gigasampler/GigaStudio format engine:
305 - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
306 cutoff settings.
307 - Got rid of resembling an ancient GSt misbehavior which did not pitch at
308 all if an up-pitch of more than 40 semi tones was requested (I don't
309 think there is any stock gig sound that requires this behavior to
310 resemble its original sound).
311 - Added support for controlling whether the individual EGADSR stages may
312 be aborted (as LinuxSampler extension to the original GigaStudio 4
313 format).
314
315 * general changes:
316 - fixed printf type errors (mostly in debug messages)
317 - use unique_ptr instead of auto_ptr when building with C++11
318 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
319 allowing to sort data efficiently in real-time safe manner.
320 - RTList class: added methods for moving/inserting elements to arbitrary
321 position within a list.
322 - RTList class: added method fromPtr() for creating an Iterator object from
323 a raw element pointer.
324 - Attempt to partly fix resetting engine channels vs. resetting engine, an
325 overall cleanup of the Reset*(), ConnectAudioDevice(),
326 DisconnectAudioDevice() API methods would still be desirable though,
327 because the current situation is still inconsistent and error prone.
328 - Active voices are now internally grouped to "Note" objects, instead of
329 being directly assigned to a keyboard key. This allows more fine graded
330 processing of voices, which is i.e. required for certain instrument
331 script features.
332 - Fix: Release trigger voices were not spawned on sustain pedal up
333 (CC #64) events.
334 - Fix: Release trigger voices can now also distinguish correctly between
335 note-off and sustain pedal up events.
336 - All engines: Increased ramp speed of volume smoother and pan smoother
337 (while slow rate of crossfade smoother is preserved) to allow quick
338 volume and pan changes by instrument scripts for instance.
339 - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
340 properly and thus were ignored for certain uses.
341 - Added new C++ API method
342 VirtualMidiDevice::SendChannelPressureToSampler().
343 - windows, 32-bit: fixed potential crashes by making sure the stack in
344 sub threads is 16-byte aligned
345 - fixed numerous compiler warnings
346 - Fixed invalid (note-on) event ID being assigned to new Note objects.
347 - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
348 fixes potential undefined behavior.
349 - Fixed Note object leak when triggering notes on keys which did not
350 have a valid sample mapped (fixes bug #252).
351 - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
352 - linuxsampler binary fix: option --create-instruments-db ignored
353 subsequent optional argument due to glibc's implementation oddity
354 which expects a "=" sign, but no space between them.
355
356 * packaging changes:
357 - removed unnecessary dependency to libuuid
358 (originated by libgig's usage of it)
359 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
360 auto detect whether it (sh/c)ould output its messages in color.
361 - Debian: Fixed packaging error about invalid "Source-Version"
362 substitution variable.
363 - Debian: Raised Debian compatibility level to Debian 9 "Stretch".
364 - Debian: Added build dependency to libsqlite3-dev for building
365 linuxsampler with instruments DB support.
366
367 * Real-time instrument scripts:
368 - Implemented scheduler for delayed MIDI events and for suspended scripts.
369 - Built-in script function "wait()": implemented support for function's
370 "duration-us" argument, thus scripts using this function are now
371 correctly resumed after the requested amount of microseconds.
372 - Built-in script function "play_note()": implemented support for
373 function's "duration-us" argument, thus notes triggered with this
374 argument are now correctly released after the requested amount of
375 microseconds.
376 - Fix: script events were not cleared when engine channel was reset,
377 potentially causing undefined behavior.
378 - Fixed crash which happened when trying to reference an undeclared
379 variable.
380 - Built-in script function "play_note()": Added support for passing
381 special value -1 for "duration-us" argument, which will cause the
382 triggered note to be released once the original note was released.
383 - Instrument script classes now exported with the liblinuxsampler C++ API.
384 - Added new API method ScriptVM::syntaxHighlighting() which provides
385 a convenient syntax highlighting backend for external instrument
386 script editor applications.
387 - Added new C++ API class "ScriptVMFactory".
388 - Extended parser issues to provide not only first line and first
389 column, but also last line and last column of issue (thus marking
390 the precise span of the issue within the source code).
391 - Reload script automatically after being modified by an instrument
392 editor.
393 - NKSP language grammar correction: allow empty event handler bodies
394 like "on note end on".
395 - Implemented built-in script function "change_vol()".
396 - Implemented built-in script function "change_tune()".
397 - Implemented built-in script function "change_pan()".
398 - Implemented built-in script function "change_cutoff()".
399 - Implemented built-in script function "change_reso()".
400 - Implemented built-in script function "event_status()".
401 - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
402 "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
403 "event_status()" function.
404 - NKSP language: Added support for bitwise operators ".or.", ".and."
405 and ".not.".
406 - NKSP language scanner: Fixed IDs matching to require at least one
407 character (i.e. when matching function names or variable names).
408 - NKSP language scanner: disabled unusued rules.
409 - Fixed behavior of play_note() and note_off() functions which must
410 be distinguished engine internally from "real" MIDI note on/off
411 events in order to avoid misbehaviors like hanging notes.
412 - Implemented built-in script variable "$KSP_TIMER".
413 - Implemented built-in script variable "$NKSP_REAL_TIMER".
414 - Implemented built-in script variable "$NKSP_PERF_TIMER".
415 - Implemented built-in script variable "$ENGINE_UPTIME".
416 - Implemented built-in script function "inc()".
417 - Implemented built-in script function "dec()".
418 - NKSP language fix: division expressions were evaluated too often.
419 - NKSP language fix: string concatenation operator was right
420 associative instead of left (to right).
421 - NKSP language correction: allow empty statements in entire language
422 (i.e. "if end if").
423 - Implemented built-in script function "stop_wait()".
424 - Implemented built-in script variable "$NI_CALLBACK_ID".
425 - Implemented built-in script variable "$NI_CALLBACK_TYPE".
426 - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
427 - Added support for read-only built-in variables (respectively
428 handled by the script parser).
429 - Added built-in script constant "$NI_CB_TYPE_INIT".

436 - Implemented built-in script function "change_release()".
437 - Fixed all change_*() built-in script functions to apply their
438 synthesis parameter changes immediately in case the respective note
439 was triggered at the same time, instead of scheduling the parameter
440 change, especially because it would cause some parameter types's
441 changes either to be ramped (i.e. change_vol()) or other types even
442 to have not effect at all (i.e. change_attack()).
443 - Implemented built-in script function "sh_left()".
444 - Implemented built-in script function "sh_right()".
445 - Implemented built-in script function "min()".
446 - Implemented built-in script function "max()".
447 - NKSP Fix: "init" event handler was not always executed when a script
448 was loaded.
449 - NKSP built-in wait() script function: abort script execution if
450 a negative or zero wait time was passed as argument (since this is
451 a common indication of a bug either of the script or even of the
452 engine, which could lead to RT instability or even worse).
453 - ScriptVM: Implemented automatic suspension of RT safety
454 threatening scripts.
455 - Provide more user friendly error messages on syntax errors.

466 - Implemented built-in script function "fade_in()".
467 - Implemented built-in script function "fade_out()".
468 - Fixed acceptance of wrong data type of parameters passed to built-in
469 script functions "change_vol()", "change_tune()", "change_pan()",
470 "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
471 "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",

473 - Added built-in script function "get_event_par()" and implemented some
474 of its possible parameter selections.
475 - Added built-in script function "set_event_par()" and implemented some
476 of its possible parameter selections.
477 - Fixed a bunch of scheduler time related bugs.
478 - Fixed polyphonic variables not being reset to zero after usage.
479 - Built-in "ignore_event()" function: argument is now optional, like with
480 built-in function "ignore_controller()".
481 - Implemented built-in script function "change_velo()".
482 - Implemented built-in script function "change_note()".
483 - Adjusted behavior of "change_vol()" and "change_tune()" to a more
484 intuitive behavior if used in combination with "change_vol_time()" or
485 "change_tune_time()" respectively: now tuning/volume changes are only
486 assigned (without delay) immediately to a new note if the respective
487 timing function has not been called before, otherwise the volume/tuning
488 changes are automatically faded (before, only the event's time stamp was
489 relevant).
490 - Implemented built-in script function "array_equal()".
491 - Implemented built-in script function "search()".
492 - Implemented built-in script function "sort()".
493 - NKSP Fix: Never suspend "init" event handlers.

495 available for gig format engine).
496 - Added built-in script constant "$NKSP_LINEAR".
497 - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
498 - Implemented built-in script function "change_vol_curve()".
499 - Implemented built-in script function "change_tune_curve()".
500 - built-in "play_note()" function now supports a sample playback start
501 offset with argument 3, where special value -1 means to use the regular
502 sample offset as defined by the instrument file.
503 - Built-in array variable %KEY_DOWN[] is now a read-only variable.
504 - Built-in variable $EVENT_NOTE is now a read-only variable.
505 - Built-in variable $EVENT_VELOCITY is now a read-only variable.
506 - built-in "play_note()" function now accepts -2 for its fourth argument
507 (note duration) which means the life time of the note shall be sticked
508 to the requested note number of argument 1.
509 - Fix: built-in "play_note()" function now returns 0 as result value if
510 -1 was passed for its fourth argument (note duration) and the respective
511 parent note is already gone.
512 - Implemented built-in script function "change_play_pos()".
513 - NKSP language: Added support for user declared const array variables.
514 - NKSP language: Raise parser warning if array variable is accessed with
515 an index that exceeds the array's size.
516 - NKSP language fix: Unknown characters were not handled correctly.
517 - NKSP language: Added support for "synchronized .. end synchronized"
518 code blocks.
519 - Implemented built-in script function "abort()" which allows to abort
520 another script handler by passing its callback ID.
521 - Fixed potential memory access bug and potential undefined behavior of
522 "init" event handlers.
523 - Print a time stamp along to each call of built-in function "message()".
524 - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
525 to retrieve all code blocks filtered out by the preprocessor.
526 - Added built-in script function "fork()".
527 - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
528 - Added built-in variable $NKSP_CALLBACK_PARENT_ID.

531 - Added built-in constant $CALLBACK_STATUS_TERMINATED.
532 - Added built-in constant $CALLBACK_STATUS_QUEUE.
533 - Added built-in constant $CALLBACK_STATUS_RUNNING.
534 - Removed max. value limitation of built-in functions "change_attack()",
535 "change_decay()" and "change_release()" to i.e. allow passing 2000000
536 for doubling the respective time.
537 - NKSP script editor syntax highlighting API: Fixed app termination due
538 to a lexer start condition stack underrun.
539 - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
540 USE_CODE_IF_NOT() preprocessor statements.
541 - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
542 can be set to disable all subsequent built-in "message()" function calls
543 on preprocessor level.
544 - Implemented built-in script function "change_sustain()".
545 - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
546 to avoid the editor app to crash on ill-formed text input.

558 undefined behavior.
559 - Cleanup of instruments DB file creation and opening code.
560 - The instrument DB path of linuxsampler's --create-instruments-db argument
561 is now optional, if it is missing, then a default location is used.
562 - Added support for scanning SFZ (.sfz) files.
563 - Added support for scanning Sound Font (.sf2) files.
564 - Fixed undefined DB transaction behavior.

581 configure
582 - Mac OS X: Makefile fix for the install-strip target
583 - fixed compilation with gcc 4.7
584 - fixed configure script error with old autoconf versions
585 - lsatomic.h: use gcc provided atomic functions if building with
586 gcc 4.7 and C++11
587 - modernized configure script
588 - fixed linkage error when building with
589 LDFLAGS="-Wl,--no-undefined" (#190)
590 - fixed compilation with Clang 3.2
591 - removed usage of deprecated Automake variable INCLUDES
592 - fixed building with C++11
593 - build fix: ChangeFlagRelaxed.h was missing in makefile

595 makefiles
596 - fix for building with bison 3.0 (#202)
597 - Mac OS X: added temporary hack allowing to spawn gigedit as callback
598 on the process's main thread
599 - fixed build error on newer MinGW
600 - support building with older jack versions

602 - enabled automake 'subdir-objects' option and moved external
603 source references (vst, au, asio) from makefiles to cpp files,
604 in order to get rid of warnings from automake 1.14
605
606 * general changes:
607 - Refactoring: moved the independent code from
608 the Gigasampler format engine to base classes
609 - command line option '--profile' is currently disabled, since the
610 respective profiling code is currently broken
611 - Introduced support for optional environment variable
612 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
613 where the sampler shall look for instrument editor plugins
614 (patch by Luis Garrido, slightly modified).
615 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
616 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
617 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
618 note (in this implementation of the sampler its simply hard routed to
619 the 1st effect send of the sampler channel, no matter what the actual
620 effect type is)
621 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
622 note (in this implementation of the sampler its simply hard routed to
623 the 2nd effect send of the sampler channel, no matter what the actual
624 effect type is)
625 - implemented support for internal LADSPA effects
626 - raised limit of program change queue from 100 to 512
627 (as suggested by Alex Stone)
628 - implemented sine LFO, pulse LFO and saw LFO
629 - experimental support for per voice equalization
630 - added command line option --exec-after-init
631 - Introduced new C++ API method:
632 EngineChannel::InstrumentFileName(int index)
633 allowing to retrieve the whole list of files used for the loaded
634 instrument on an engine channel (a.k.a. part). Some GigaStudio
635 instruments for example are splitted over several files like
636 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
637 - Added new C++ API method Sampler::GetGlobalMaxVoices().
638 - Added new C++ API method Sampler::GetGlobalMaxStreams().
639 - Added new C++ API method Sampler::SetGlobalMaxVoices().
640 - Added new C++ API method Sampler::SetGlobalMaxStreams().
641 - Various "const" and "restrict" optimizations.
642 - all engines: add pan CC value to instrument pan parameter before
643 applying panning, instead of using two separate pan functions in
644 series (#182)
645 - added a lock guard class for exception safe mutex handling and
646 used it everywhere appropriate
647 - Immediately apply scale tuning changes to active voices.
648 - Exposed scale tuning to C++ API (along to the already existing standard
649 SysEx way).
650 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
651 and broken for ppc64. (Seq_cst loads and stores are actually not
652 used in LS, so the bug wasn't noticable.)
653 - lsatomic.h: added ARMv7 support
654 - Added support for multiple MIDI input ports per sampler channel (and
655 added various new C++ methods for this new feature / design change, old
656 C++ API methods for managing SamplerChannel's MIDI inputs are now marked
657 as deprecated but are still there and should provide full behavior
658 backward compatibility).
659 - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
660 unsafe and caused compilation error with clang 2.x).
661 - Bugfix: only process the latest MIDI program change event.
662 - Introducing the LSCP shell, which provides convenient control of the
663 sampler from the command line by providing LSCP aware features.
664 - VirtualMidiDevice: Added support for program change.
665 - VirtualMidiDevice: Added support for bank select (MSB & LSB).
666 - VirtualMidiDevice: Added support for pitch bend.
667 - Aftertouch: extended API to explicitly handle channel pressure and
668 polyphonic key pressure events (so far polyphonic pressure was not
669 supported at all, and channel pressure was rerouted as CC128 but not
670 used so far).
671 - Added initial support for real-time instrument scripts. The script VM
672 code is shared by all sampler engine implemementations, however only the
673 gig file format currently provides support for storing instrument scripts
674 (as LinuxSampler extension to the original GigaStudio 4 format).
675
676 * Gigasampler format engine:
677 - implemented the "round robin keyboard" dimension
678 - fixed round robin and random dimensions for cases when number of
679 dimension zones is not a power of two

681 key
682 - bugfix: pitch LFO controller "internal+aftertouch" was broken
683 - bugfix: filter keyboard tracking was broken
684 - filter performance fix (an unnecessary copy was made of the
685 filter parameters in each sub fragment)
686 - handle special case when pan parameter in gig file has max or
687 min value
688 - Exclusive Groups: don't ever stop voices of the same note,
689 doesn't sound naturally with a drumkit
690 - fixed EG1 modulation when attack or release is zero
691 - Fixed support for 'aftertouch' attenuation controller.
692 - Fixed crash that happened with velocity split sounds under certain
693 conditions (see also previous commit on libgig).
694 - fixed behaviour of filter LFO
695
696 * SFZ format engine:

726 - added support for loop_mode=one_shot
727 - fixed playback of 16 bit wav files on big endian CPUs
728 - added support for Ogg Vorbis sample files
729 - use loop markers from sample file if loop_start and loop_end are
730 not set in sfz file
731 - implemeted filters. Filter types: lowpass, bandpass, bandreject
732 and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,
733 cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
734 cutoff_cc, cutoff_chanaft.
735 - bugfix: zero ampeg_sustain didn't work

872 - Listen to all interfaces on Mac OS X (INADDR_ANY)
873 - VST bugfix: If the host called resume() before and after
874 changing sample rate or block size, the number of channels was
875 incorrectly set to two. This caused silence in Cubase 5.

922 to them a la JACK, via the usual sampler APIs
923 - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
924 the driver will automatically connect to other CoreMIDI clients' ports
925 (e.g. external MIDI devices being attached to the Mac)
926 - added support for MIDI note on velocity filter
927 - CoreMIDI: fixed memory deallocation error
928 - Fixed variable underflow in VirtualMidiDevice, which caused graphical
929 virtual keyboards in frontends / instrument editors being stuck.
930 - Bugfix in VirtualMidiDevice: process note on with velocity 0 as note off.

999 - Added support for moving cursor left/right with arrow keys.
1000 - Added support for built-in LSCP reference documentation, which will

1049 "gig_set_dim_zone()" now also accept an array of event IDs as argument
1050 (i.e. return value of new script function "by_marks()").
1051 - Pass/preserve polyphonic variable data from respective "note" event
1052 handler to "release" event handler.
1053 - Fixed crash when using built-in script function "by_marks()".
1054

1059 channel to a different engine type
1060 - fixed crash when deleting a sampler channel or changing engine
1061 type while an instrument load was in progress
1062 - bugfix: playing a note while changing the instrument could cause
1063 a crash, or give "Handing back unknown region" error messages
1064 - bugfix: calling SET VOICES (which Fantasia does on start and
1065 refresh) could cause instruments to be unloaded
1066 - Mac OS X: fixed name collision of enum in EffectControl and
1067 wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
1068 - Mac OS X: fixed hanging threads
1069 - Windows: disabled the previous thread fix on non-Mac systems, as
1070 it caused hanging threads on Windows
1071 - Fixed possible crashes due to corrupted MIDI/audio device list
1072 after MIDI/audio device creation failure
1073 - When creating MIDI instrument map entries with "PERSISTENT" type, the
1074 instruments were uselessly precached with zero samples, however it still
1075 took the full preloading time and on 1st program change the respective
1076 instrument was completely reloaded again.
1077 - fixed handling of rapid bank select and program change messages
1078 sent to the same sampler channel (patch from the Open Octave
1079 project, slightly adjusted)
1080 - fixed crash when trying to create an effect instance with controls
1081 which min and/or max values depend on the sample rate

1098 crashes and noise on such transitions).
1099 - ignore missing LADSPA paths without ignoring valid LADSPA paths
1100 (fixes #208)
1101 - Fixed bug in LSCP grammar definition which caused a statement like
1102 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1103 practically irrelevant, however it caused problems with the new LSCP
1104 shell's auto completion feature).
1105 - Fixed MIDI program change messages being ignored if quickly executed
1106 after each other (fixes #231).
1107
1108 Version 1.0.0 (31 July 2009)
1109
1110 * packaging changes:
1111 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
1112 causing e.g. the libgig test to fail when
1113 "./configure --disable-jack-driver" was used
1114 (patch by Alexis Ballier)
1115 - fixed compilation with gcc 4.3
1116 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)

1121 - minor fix in configure for mmsystem.h detection on MinGW
1122 - Windows: look for editor plugins and Fantasia using base
1123 directory of liblinuxsampler dll (look in the same directory and one
1124 directory above)
1125 - configure script fix: removed unconditional use of SSE
1126 - fixed building with sqlite installed in a non-standard directory
1127 - when cross-compiling, don't try to create instruments.db
1128 - fix for new mingw-w64 version, which has usleep
1129
1130 * general changes:
1131 - bugfix: on some POSIX systems instrument editor plugins refused to
1132 load as we used a non-portable Linux specific struct field
1133 (fixes bug #70, patch by Ronald Baljeu)
1134 - fixed endless loop which occured when loading an instrument editor
1135 plugin DLL on Windows systems failed
1136 - fixed memory leaks that occurred when liblinuxsampler was unloaded
1137 - optimized the SynchronizedConfig class so it doesn't wait
1138 unnecessarily long after an update
1139 - added support for notifying instrument editors on note-on / note-off
1140 events (e.g. to highlight the pressed keys on the virtual keyboard
1141 of gigedit)
1142 - added support for triggering notes by instrument editors (see above)
1143 - be verbose on DLL load errors (on Linux)
1144 - fixed di-harmonic triangle LFO implementation (this LFO implementation
1145 is only used by very few systems, most pick the int math
1146 implementation, which is usually faster)
1147 - fixes for audio drivers with varying buffer sizes
1148 - experimental support for running LinuxSampler as a DSSI, LV2 and
1149 VST plugin
1150 - notification events for stream/voice count statistics are now sent
1151 only when there are actual changes
1152 - added memory ordering constraints to improve stability on
1153 multi-core and multi-cpu systems
1154 - maximum voices and disk streams can now be altered at runtime
1155 - fixed CPU feature detection on x86_64 (maybe fixes #108)
1156 - automatic stacktrace mechanism is now turned off by default and can
1157 be switched on by command line option "--stacktrace" (the automatic
1158 stacktrace mechanism seems to be broken on most systems at the moment)
1159 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
1160 a pointer to the launched InstrumentEditor object
1161 - added optional 3rd party user data parameter for following
1162 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
1163 InstrumentEditor::Launch(),
1164 InstrumentManager::LaunchInstrumentEditor()
1165 - theoretical fix: made SynchronizedConfig follow C++0x memory
1166 model more strictly
1167 - fixes for using large audio device buffers
1168 - Windows: add the installation directory to the DLL search path
1169 when loading an editor plugin (solves problems with VST and
1170 gigedit on systems with other GTK versions installed)
1171 - updated linuxsampler man page
1172
1173 * audio driver:
1174 - removed the nonsense audio channel constraint (which was hard coded to
1175 max. 100 audio channels) for most audio drivers
1176 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
1177 opposed to the LSCP specs
1178 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
1179 reflected the wrong value
1180 - fixed a memory management bug in ASIO driver
1181 - Makefile fix: JACK_CFLAGS wasn't used
1182 - JACK: use jack_client_open instead of the deprecated
1183 jack_client_new
1184 - added (experimental) CoreAudio driver
1185 - applied old fixes to the ASIO driver that were included in the
1186 previous binary release but accidentally never committed to CVS
1187 (fixes #117)
1188 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
1189 win64)
1190 - VST: added support for sample rate and buffer size changes
1191 - VST: close editor (Fantasia) when the VST is removed
1192 - VST: avoid opening Fantasia more than once for each VST instance
1193 - VST: export main function as "main" on Linux too (fix for
1194 energyXT)
1195 - VST: changed number of output channels from one stereo to 16
1196 stereo
1197 - added channel routing, fxsends and midi maps to the settings
1198 stored in the plugin state
1199 - performance optimization of AudioChannel::MixTo() and
1200 AudioChannel::CopyTo() methods using GCC vector exensions
1201 (if available)
1202 - ASIO fixes: avoid initializing the device twice, avoid throwing
1203 exception when getting parameters from a disconnected device
1204
1205 * MIDI driver:
1206 - added JACK MIDI driver
1207 - dispatch bank select as ordinary CC as well, the user might seriously
1208 want to (mis)use it for some purpose ("fixed" in all current MIDI
1209 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
1210 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
1211 CoreMidi or AU
1212 - fixed mingw-w64 compilation error in MME driver
1213 - made program change handling in MIDI thread real-time safe by
1214 moving the logic to a non-RT thread
1215 - fixed minor memory leak in ALSA driver
1216
1217 * instruments database:
1218 - avoid time consuming samples scanning when adding instruments
1219 to the instruments database
1220 - added support for handling lost files in the instruments database
1221 - Implemented option for adding instruments in separate directories
1222 in the instruments database
1223 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
1224 - work-around for missing fnmatch function on Windows to make
1225 instrument database compilable
1226 - added instrument database support on Windows
1227 works with both standalone mode and VST plugin.
1228 the instruments DB file is located in
1229 %USERPROFILE%\.linuxsampler\instruments.db which allows different
1230 databases for each windows user
1231 if no DB is present it automatically creates the .linuxsampler subdir
1232 and then creates an empty DB
1233 - fixed recursive import, which was broken on Windows
1234
1235 * Gigasampler format engine:
1236 - fixed a memory leak that could happen when a channel was deleted
1237 while notes were playing
1238 - made it possible to load an instrument even if the audio thread
1239 isn't running
1240 - added partial support for the "Controller Triggered" MIDI rule,
1241 enough for piano gigs with pedal noise samples
1242 - minor fix: only mark FX sends as being modified if really the
1243 respective FX send MIDI controller was used
1244 - added support for GM global device volume SysEx message
1245 (can be selected at compile time to either apply globally to the
1246 whole sampler [default] or only to the sampler channels that are
1247 connected to the respective MIDI input port the SysEx message arrived
1248 on)
1249 - bugfix: notes triggered at position 0 in the audio buffer were
1250 sometimes wrongly killed in the same buffer, causing no sound to
1251 be played
1252 - added support for chromatic / drumkit mode Roland GS Sysex message
1253 which is usally used to switch a part between chromatic sounds and
1254 drumkit sounds (as opposed to their common default setting of MIDI
1255 part 10 being a drumkit part and all other ones chromatic parts), in
1256 LS however one can switch between the first 16 MIDI instrument maps
1257 defined for the sampler
1258 - made it possible to create multiple sample channels even if the
1259 audio thread isn't running
1260 - fixed crash when removing channel with active voices (#116)
1261 - bugfix: on sample reference changes (instrument editor), only
1262 un-cache the respective sample if it's really not used by any
1263 sampler engine anymore
1264 - re-cache samples in case they were changed by an instrument editor,
1265 e.g. when a sample was added while playing (#82)
1266 - fixed hanging notes which occured when note-off event had the exact
1267 same time stamp as the voice's note-on event and occured both in the
1268 same audio fragment cycle (fixes bug #112)
1269 - added support for the "fine tune" and "pitch bend range"
1270 instrument-level gig parameters
1271 - fixed minor artifacts in pitch bend handling
1272 - added support for GS Reset SysEx message
1273 - allow gig files to use unlimited downward pitch shifting
1274 - added a limit check for upward pitch shifting
1275 - bugfix: sometimes, when playing a note twice fast, the second
1276 note was silent
1277 - fixed crash happening when a pitch bend event arrived at the
1278 same time a new instrument was loading
1279
1280 * LSCP server:
1281 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
1282 react on MIDI data arriving on certain sampler channels (so far only
1283 Note-On and Note-Off events are sent via this LSCP event)
1284 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1285 react on MIDI data arriving on certain MIDI input devices (so far only
1286 Note-On and Note-Off events are sent via this LSCP event)
1287 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
1288 SET DB_INSTRUMENT FILE_PATH
1289 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
1290 frontends to send MIDI messages to specific sampler channel
1291 - added two additional fields to GET FILE INSTRUMENT INFO command -
1292 KEY_BINDINGS and KEYSWITCH_BINDINGS
1293 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1294 was incorrect
1295 - Optimized the retrieval of the MIDI instrument mappings
1296 - added new LSCP command "SET VOICES" to globally alter the maximum
1297 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1298 be triggered respectively
1299 - added new LSCP command "SET STREAMS" to globally alter the maximum
1300 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1301 which will be triggered respectively
1302 - bugfix: retry if "select" returns EINTR (this fixes a crash when
1303 a gigedit file dialog is opened)
1304 - close all connections when LSCPServer is deleted
1305 - hard close of all sockets on exit
1306 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
1307 driver
1308
1309 * Bug fixes:
1310 - fixed a crash which occurs when removing a sampler channel waiting
1311 to start instrument loading after another channel
1312 - fixed a crash which occurs when removing a sampler channel with
1313 instrument loading in progress (bug #113)
1314 - fixed termination caused by uncaught exception when adding MIDI
1315 instrument with PERSISTENT load mode
1316 - fixed possible iterator invalidations when resetting the sampler
1317 - fixed memory leaks when issuing the following LSCP commands:
1318 GET AUDIO_OUTPUT_DRIVER INFO
1319 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
1320 GET MIDI_INPUT_DRIVER INFO
1321 GET MIDI_INPUT_DRIVER_PARAMETER INFO
1322 - fixed possible compilation error when sqlite is not present
1323 - fixed orphaned pointers when setting maximum voices limit (bug #118)
1324 - fixed crash when changing the audio output device of a sampler
1325 channel with loaded instrument and start playing notes
1326 - fixed endless loop in Engine::SuspendAll() (bug #120)
1327 - fixed a low-level atomic load function that was broken on 64-bit
1328 PowerPC, which probably could cause crashes on that platform
1329 - fixed a memory management error which could cause a crash when a
1330 plugin was unloaded
1331 - bugfix: two private structs had the same name, which could cause
1332 problems if the linker chose the wrong constructor
1333 - fixed low-level ConditionServer usage bug that caused lockups on
1334 Windows
1335
1336
1337 Version 0.5.1 (6 December 2007)
1338
1339 * packaging changes:
1340 - added autoconf checks for pthread library
1341 - added autoconf check for pthread bug found on certain NPTL-enabled
1342 glibc versions (see Gentoo bug report #194076)
1343 - added autoconf checks for MS Windows
1344
1345 * general changes:
1346 - bugfix: the thread used by an editor plugin didn't die when the
1347 editor closed
1348 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1349 out all the space. operator--() did not apply size_mask after
1350 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1351 order to avoid problems with the _NonVolatileReader functions.
1352 - bugfix: Stream.h: added a missing divide by BytesPerSample in
1353 GetWriteSpace(). Since this function is currently only used in
1354 the stream's qsort() compare function, it didn't trigger any
1355 bugs.
1356 - Resampler.h, Synthesizer.h: cubic interpolation now works in
1357 24bit mode too. Faster method to read 24bit words on little
1358 endian machines (x86): replaced 3 byte reads + shifts with a 1
1359 unaligned 32bit read and shift
1360 - experimental support for MS Windows (MIDI input via MME, AUDIO
1361 output via ASIO)
1362 - made handling of SIGINT signal (Ctrl-C) a bit more robust
1363 - support for monitoring the total number of active disk streams
1364 (new LSCP commands: GET TOTAL_STREAM_COUNT,
1365 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1366
1367 * AUDIO driver:
1368 - added Windows ASIO low latency audio driver
1369
1370 * MIDI driver:
1371 - added MME Windows MIDI driver
1372
1373 * LSCP server:
1374 - added support for Windows style path / filenames, however with
1375 forward slash path separators instead of backslash
1376 (i.e. "C:/foo/bar.gig")
1377 - allow naughty liblscp to send non-string device parameters within
1378 apostrophes as well
1379 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1380 "LIST FILE INSTRUMENTS <file>" and
1381 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1382 about an arbitrary instrument file on the system where the sampler is
1383 running on
1384
1385 Version 0.5.0 (15 October 2007)
1386
1387 * packaging changes:
1388 - config.h is not going to be installed along with liblinuxsampler's
1389 API header files anymore
1390 - only the API relevant header (and source) files will be exported to
1391 the Doxygen API documentation (explicitly listed in Doxyfile.in)
1392 - added completely new XCode project files for Mac OSX which is now
1393 capable to execute our autoconf environment, thus no need anymore
1394 to maintain the compile time configuration file (osx/version.h) for
1395 OSX manually (patch by Toshi Nagata)
1396 - fixed buggy boolean --enable-foo / --disable-foo configure script
1397 parameters
1398 - global.h now only covers global definitions that are needed for the
1399 C++ API header files, all implementation internal global definitions
1400 are now in global_private.h
1401 - atomic.h is not exposed to the C++ API anymore
1402 - no need to include config.h anymore for using LS's API header files
1403 - fixed warnings in API doc generation
1404
1405 * general changes:
1406 - replaced the old, confusing MIDI program change mechanism by a
1407 flexible MIDI instrument mapper which allows to map arbitrary
1408 (MIDI bank, MIDI program) pairs with arbitrary
1409 (engine type, instrument file, file index) triplets which will be
1410 loaded on the respective channel when such MIDI program change
1411 messages arrive, beside that, each entry allows to define a life-time
1412 strategy for the instrument, so the user can define whether the
1413 instrument should i.e. be permanently loaded (to be able to switch
1414 quickly among sounds) or i.e. loaded just on demand when the
1415 respective program change arrives (to safe RAM space), as well as a
1416 global volume factor for each entry, so the user can adjust the volume
1417 dynamic of his mapped instrument collection without having to modify
1418 the instrument files, also one can manage arbitrary amount of such
1419 MIDI instrument maps and assign each sampler channel individually
1420 a certain map, so that i.e. separation of normal instruments and
1421 drumkits is possible
1422 - new notification events for tracking changes to audio/MIDI devices,
1423 MIDI instrument maps, MIDI instruments, FX sends, global volume.
1424 - sampler was limited to load max. 200 instruments in the background
1425 due to a constant size RingBuffer FIFO which is now replaced by a
1426 dynamic (unlimited) size std::list FIFO
1427 - added FX sends, these allow to route audio signals to arbitrary audio
1428 output channels for being processed by external effect processors
1429 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1430 controllers
1431 - global (sampler wide) volume can now be controlled at runtime
1432 - Implemented new, improved notification system
1433 - fixed compilation errors regarding OSX
1434 (patch by Toshi Nagata)
1435 - implemented instruments database
1436 - added support for escape sequences to the instruments database
1437 - added highly experimental support for on-the-fly instrument editing
1438 within the sampler's process (by using instrument editor plugins),
1439 you'll notice the new "Registered instrument editors:" message on
1440 startup, added a new LSCP command:
1441 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1442 to spawn a matching instrument editor for the instrument on the
1443 given sampler channel, the plugin path can be overridden at compile
1444 time with ./configure --enable-plugin-dir=/some/dir
1445 - added experimental code for synchronizing instrument editors hosted
1446 in the sampler's process to safely edit instruments while playing
1447 without a crash (hopefully) by either suspending single regions
1448 wherever possible or if unavoidable whole engine(s)
1449 - fixed several issues in fundamental "Thread" class: set scheduling
1450 policy and priority on thread level, set a minimum stack size for
1451 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1452 threads simply inherited properties of starting thread instead of
1453 setting their own policy and priority
1454 - minor fix in our automatic stack trace mechanism on crashes, the
1455 main process did not wait for the stack trace process to finish
1456 its output
1457 - fixed some minor memory leaks
1458 - reenabled assembly features support, at the moment only for
1459 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1460 - minor assembly fix in x86 features detection (don't use the PIC
1461 register, to avoid relocations in the text segment at runtime)
1462 - POSIX callback functions of Thread.h are hidden
1463
1464 * MIDI driver:
1465 - dispatch bank select (MSB and LSB) messages
1466
1467 * audio driver:
1468 - the ALSA audio output driver parameters now reflect the correct
1469 parameter value ranges for the respective selected sound card
1470 (patch by Till Wimmer, a bit fixed and extended)
1471
1472 * Gigasampler format engine:
1473 - if a filter is used and EG2 finishes before EG1, let the voice
1474 die when EG2 has finished (this fixes a problem with clicks and
1475 voice starvation for some gigs)
1476 - playback is no longer disabled during instrument loading
1477 - all notes playing on a channel that changes its instrument keep
1478 playing with the old instrument until they get a note off
1479 command
1480 - EG fix: a release value of zero could cause noises or crash
1481 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1482 - EG fine tuning: when attack is zero the EG starts at a level
1483 above max sustain level, which means that there is a decay phase
1484 even if sustain is 100%
1485 - more EG fixes: the level could sometimes go below zero and cause
1486 noises or crashes
1487 - minor fix of EGDecay (patch by Toshi Nagata)
1488 - fixed compiler error when --enable-override-filter-type was
1489 supplied to the configure script (fixes #46)
1490 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1491 instead of a fix value
1492 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1493 127 (solo mode) only kill voices if the respective mode really
1494 changed
1495
1496 * LSCP server:
1497 - fixed compile time error for old Bison versions
1498 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1499 - parser now supports extended ASCII character set
1500 (up to ASCII code 255, i.e. includes now umlauts and accents)
1501 - filename arguments in LSCP commands now allow to use escape
1502 sequences, that is directly literal as one of: \', \", \\, \n, \r,
1503 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1504 code value like \xf2) (fixes bug #24)
1505 - the following LSCP commands now also support escape sequences for at
1506 least one of their text-based parameters (i.e. name, description):
1507 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1508 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1509 "SET DB_INSTRUMENT_DIRECTORY NAME",
1510 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1511 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1512 "FIND DB_INSTRUMENT_DIRECTORIES"
1513 - returns verbose syntax errors (line and column where syntax error
1514 occured, the unexpected character and the actually expected, possible
1515 character(s), the latter only if less than 5 possibilities)
1516 - made sure that LSCP syntax is not affected by gigedit locale
1517 settings
1518 - bugfix regarding strings parameter lists: all comma separated lists
1519 of strings were treated as being one string containing commas
1520 (fixes #57)
1521
1522 * Bug fixes:
1523 - fixed crash occurring on certain LSCP scripts (Bug 39)
1524 - another thread safety fix for lscp "load engine" and "set
1525 channel audio output device"
1526 - fixed a crash which occurs when reassigning the same engine
1527 on a sampler channel with connected MIDI device
1528 - fixed a crash which occurs when changing the number of ports of a MIDI
1529 device connected to a sampler channel to number less then or equal
1530 to the index of the port to which the sampler channel is connected.
1531 - The previous bindings were not been disconnected when altering
1532 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1533 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1534 - The active stream/voice count statistic was incorrect.
1535 - notification events were not been sent for some sampler
1536 channel changes
1537 - added default min and max values to restrict the number of allowed
1538 audio output channels and MIDI input ports
1539 - the connection to the PCM interface is now closed when destroying
1540 an audio output device
1541 - files with slash in their path or filename could not be loaded
1542
1543 * test cases:
1544 - updated and fixed (haven't been touched in a while)
1545
1546 Version 0.4.0 (24 November 2006)
1547
1548 * packaging changes:
1549 - changed deprecated copyright attribute to license; added ldconfig
1550 to post-(un)install steps; added devel package for liblinuxsampler;
1551 to linuxsampler.spec (RPM)
1552 - install necessary development header files for allowing 3rd party
1553 applications to link against liblinuxsampler
1554 - liblinuxsampler's API documentation can be generated with 'make docs'
1555 (Doxygen required)
1556 - added benchmark to automatically detect the best triangle LFO
1557 implementation (currently either an integer math solution or a
1558 di-harmonic approximation), automatic detection can be overriden
1559 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1560 configure script argument though (mandatory for cross-compilation)
1561 - do not automatically pick optimized gcc flags if the user already
1562 provided some on his own (as CXXFLAGS)
1563 - added compile time option to disable processing of All-Notes-Off MIDI
1564 messages
1565 - added compile time options to allow disabling the various audio and
1566 MIDI drivers
1567 - fixed automatic GCC CPU switch detection on PPC
1568 (patch by Ebrahim Mayat)
1569
1570 * Gigasampler format engine:
1571 - extensive synthesis optimization
1572 (reimplementation of EGs and LFO(s), removed synthesis parameter
1573 prerendering and the synthesis parameter matrix in general, splitting
1574 each audio fragment into subfragments now where each subfragment uses
1575 constant pitch and filter coefficients. The volume coefficient is
1576 linearly interpolated inside a subfragment, unless
1577 --disable-interpolate-volume is set.)
1578 - fine tuning of the EG modulation parameters
1579 - improved filter cutoff calculation by adding support for the
1580 following gig parameters: Cutoff freq (used when no cutoff
1581 controller is defined), Control invert, Minimum cutoff, Velocity
1582 curve and Velocity range. The keyboard tracking now scales
1583 cutoff frequency instead of resonance.
1584 - added support for gig parameter Resonance.
1585 - fixed bug in sysex handling (patch by Juan Linietsky)
1586 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1587 which can be overridden with --enable-global-attenuation
1588 - EG fixes: made the length of "attack hold" stage more
1589 accurate. Release stage can now start before attack stage
1590 ends. Cancel release didn't work when sustain was zero. Attack
1591 time now has a minimal value to prevent clicks.
1592 - fixed pitch changes larger than one octave
1593 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1594 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1595 all modes can be altered via standard GM messages, that is CC5 for
1596 altering portamento time, CC65 for enabling / disabling portamento
1597 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1598 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1599 parameter) and crossfade
1600 - added support for the "attenuation controller threshold" gig
1601 parameter
1602 - added smoothing of volume changes caused by control change
1603 messages
1604 - sample loop parameters are now taken from the DimensionRegion
1605 instead of the wave chunk
1606 - fixed keyswitching for v3 gigs with a number of keyswitch splits
1607 not equal to a power of two
1608 - reimplementation of the filter algorithm. The new filter is more
1609 accurate and supports all gig filter types, including bandreject
1610 and lowpass turbo.
1611 - real support for 24 bit samples - samples are not truncated to
1612 16 bits anymore
1613 - support for aftertouch (channel pressure, not polyphonic
1614 aftertouch)
1615 - LFO1 behaviour fixed (dampening from max volume instead of
1616 amplifying from 0)
1617
1618 * LSCP server:
1619 - fixed application exit on broken pipe error (fixes bug #20)
1620 - fixed the notification messages delay due to lack of
1621 network activity (fixes bug #26)
1622 - fixed parser bug which occured on space(s) within device parameters
1623 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1624
1625 * audio driver:
1626 - added aRts audio output driver (by no means RT safe)
1627
1628 * MIDI driver:
1629 - fixed legacy sysex code which caused dispatching of MIDI SysEx
1630 messages several times instead of once
1631 - API extension for MIDI drivers which already supply exact time stamps
1632 for events (i.e. for offline rendering based MIDI drivers)
1633 - added checks for bad MIDI data
1634
1635 * linuxsampler application:
1636 - show available sampler engine types on startup
1637
1638 * general changes:
1639 - support for muting sampler channels and solo mode of the same, two new
1640 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1641 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1642 introduced for this, the behavior is the same like on a mixer console
1643 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1644 --enable-process-muted-channels which can be used to enable the
1645 processing of muted channels.
1646 - support for sostenuto pedal
1647 - support for monitoring the total number of active voices
1648 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1649 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1650 - fixed some memory management errors
1651 - fixed some concurrency problems that could lead to crashes when
1652 LSCP commands were executed
1653 - fixed crash when instrument loading failed previously on the same
1654 sampler channel (fixes bug #36)
1655
1656 Version 0.3.3 (15 July 2005)
1657
1658 * packaging changes:
1659 - fixed compilation with gcc 4.0
1660
1661 * Gigasampler format engine:
1662 - LFO preprocessing was performed even though the respective LFO was
1663 disabled by the instrument patch (minor efficiency fix)
1664 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1665 for volume ramp downs in the same fragment (needed for current voice
1666 stealing implementation) then simply inform the user with a warning
1667 about possible click sounds and reduce the volume ramp down
1668 appropriately instead of cancelling the audio device connection
1669
1670 Version 0.3.2 (24 June 2005)
1671
1672 * packaging changes:
1673 - updated autotools build files to compile on OS X
1674 (conditional compilation of CoreMIDI and MidiShare drivers)
1675 - hand-crafted assembly optimization code can be disabled with
1676 './configure --disable-asm' (definitely not recommended)
1677 - fixed 'make dist' rule to include all necessary files
1678 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1679 (due to 'dist-bzip2' automake option)
1680
1681 * Gigasampler format engine:
1682 - support for the gig parameters for "release velocity response" curves
1683 - fine tuning of the EGADSR envelope
1684 - volume of release triggered samples now depends on note-on velocity,
1685 note length and gig parameter "release trigger decay" instead of
1686 note-off velocity.
1687 - revised voice stealing
1688 (fixes crash and endless loop caused by voice stealing)
1689 - don't reset scale tuning on instrument or audio output device change
1690 - handle key group conflicts right at the beginning of each fragment
1691 instead of when the respective voice is actually launched
1692 (fixes undefined behavior if stolen voices belonged to a key group -
1693 this case was followed by a "killed voice survived" error message)
1694 - fixed minor issue with null/silence samples
1695 (those stole voices even though they don't need a voice at all which
1696 resulted in "voice stealing didn't work out" messages)
1697 - don't reset volume, pan, pitch and MIDI controller values on
1698 instrument or audio output device change
1699
1700 * LSCP server:
1701 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1702 - fixed LSCP event "CHANNEL_INFO" notification
1703 (e.g. did not notify on volume changes or MIDI program change events)
1704
1705 * linuxsampler application:
1706 - added command line parameters --lscp-addr and --lscp-port to override
1707 default IP address and port of LSCP server
1708
1709 Version 0.3.1 (24 May 2005)
1710
1711 * initial release
