File size: 93870 byte(s)
* Gig engine: Changed default wave form for all 3 LFOs to sine
  (instead of triangle; see discussion "GigaStudio LFO
  compatibility" on mailing list from 2019-09-26 for details).
* Bumped version (2.1.1.svn21).

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

455 script functions "change_vol()", "change_tune()", "change_pan()",
456 "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
457 "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",

462 of its possible parameter selections.
463 - Fixed a bunch of scheduler time related bugs.

469 - Adjusted behavior of "change_vol()" and "change_tune()" to a more
470 intuitive behavior if used in combination with "change_vol_time()" or
471 "change_tune_time()" respectively: now tuning/volume changes are only
472 assigned (without delay) immediately to a new note if the respective
473 timing function has not been called before, otherwise the volume/tuning
474 changes are automatically faded (before, only the event's time stamp was
475 relevant).
476 - Implemented built-in script function "array_equal()".
477 - Implemented built-in script function "search()".
478 - Implemented built-in script function "sort()".

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

519 - Added built-in constant $CALLBACK_STATUS_RUNNING.
520 - Removed max. value limitation of built-in functions "change_attack()",
521 "change_decay()" and "change_release()" to i.e. allow passing 2000000
522 for doubling the respective time.
523 - NKSP script editor syntax highlighting API: Fixed app termination due
524 to a lexer start condition stack underrun.
525 - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
526 USE_CODE_IF_NOT() preprocessor statements.
527 - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
528 can be set to disable all subsequent built-in "message()" function calls
529 on preprocessor level.
530 - Implemented built-in script function "change_sustain()".
531 - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
532 to avoid the editor app to crash on ill-formed text input.

591
592 * general changes:
593 - Refactoring: moved the independent code from
594 the Gigasampler format engine to base classes
595 - command line option '--profile' is currently disabled, since the
596 respective profiling code is currently broken
597 - Introduced support for optional environment variable
598 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
599 where the sampler shall look for instrument editor plugins
600 (patch by Luis Garrido, slightly modified).
601 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
602 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
603 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
604 note (in this implementation of the sampler its simply hard routed to
605 the 1st effect send of the sampler channel, no matter what the actual
606 effect type is)
607 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
608 note (in this implementation of the sampler its simply hard routed to
609 the 2nd effect send of the sampler channel, no matter what the actual
610 effect type is)
611 - implemented support for internal LADSPA effects
612 - raised limit of program change queue from 100 to 512
613 (as suggested by Alex Stone)
614 - implemented sine LFO, pulse LFO and saw LFO
615 - experimental support for per voice equalization
616 - added command line option --exec-after-init
617 - Introduced new C++ API method:
618 EngineChannel::InstrumentFileName(int index)
619 allowing to retrieve the whole list of files used for the loaded
620 instrument on an engine channel (a.k.a. part). Some GigaStudio
621 instruments for example are splitted over several files like
622 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
623 - Added new C++ API method Sampler::GetGlobalMaxVoices().
624 - Added new C++ API method Sampler::GetGlobalMaxStreams().
625 - Added new C++ API method Sampler::SetGlobalMaxVoices().
626 - Added new C++ API method Sampler::SetGlobalMaxStreams().
627 - Various "const" and "restrict" optimizations.
628 - all engines: add pan CC value to instrument pan parameter before
629 applying panning, instead of using two separate pan functions in
630 series (#182)
631 - added a lock guard class for exception safe mutex handling and
632 used it everywhere appropriate
633 - Immediately apply scale tuning changes to active voices.
634 - Exposed scale tuning to C++ API (along to the already existing standard
635 SysEx way).
636 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
637 and broken for ppc64. (Seq_cst loads and stores are actually not
638 used in LS, so the bug wasn't noticable.)
639 - lsatomic.h: added ARMv7 support
640 - Added support for multiple MIDI input ports per sampler channel (and
641 added various new C++ methods for this new feature / design change, old
642 C++ API methods for managing SamplerChannel's MIDI inputs are now marked
643 as deprecated but are still there and should provide full behavior
644 backward compatibility).
645 - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
646 unsafe and caused compilation error with clang 2.x).
647 - Bugfix: only process the latest MIDI program change event.
648 - Introducing the LSCP shell, which provides convenient control of the
649 sampler from the command line by providing LSCP aware features.
650 - VirtualMidiDevice: Added support for program change.
651 - VirtualMidiDevice: Added support for bank select (MSB & LSB).
652 - VirtualMidiDevice: Added support for pitch bend.
653 - Aftertouch: extended API to explicitly handle channel pressure and
654 polyphonic key pressure events (so far polyphonic pressure was not
655 supported at all, and channel pressure was rerouted as CC128 but not
656 used so far).
657 - Added initial support for real-time instrument scripts. The script VM
658 code is shared by all sampler engine implemementations, however only the
659 gig file format currently provides support for storing instrument scripts
660 (as LinuxSampler extension to the original GigaStudio 4 format).
661

667 key
668 - bugfix: pitch LFO controller "internal+aftertouch" was broken
669 - bugfix: filter keyboard tracking was broken
670 - filter performance fix (an unnecessary copy was made of the
671 filter parameters in each sub fragment)
672 - handle special case when pan parameter in gig file has max or
673 min value
674 - Exclusive Groups: don't ever stop voices of the same note,
675 doesn't sound naturally with a drumkit
676 - fixed EG1 modulation when attack or release is zero
677 - Fixed support for 'aftertouch' attenuation controller.
678 - Fixed crash that happened with velocity split sounds under certain
679 conditions (see also previous commit on libgig).
680 - fixed behaviour of filter LFO
681
682 * SFZ format engine:

712 - added support for loop_mode=one_shot
713 - fixed playback of 16 bit wav files on big endian CPUs
714 - added support for Ogg Vorbis sample files
715 - use loop markers from sample file if loop_start and loop_end are
716 not set in sfz file
717 - implemeted filters. Filter types: lowpass, bandpass, bandreject
718 and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,
719 cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
720 cutoff_cc, cutoff_chanaft.
721 - bugfix: zero ampeg_sustain didn't work

857 - AU bugfix: failed to destroy its audio/MIDI devices
858 - Listen to all interfaces on Mac OS X (INADDR_ANY)
859 - VST bugfix: If the host called resume() before and after
860 changing sample rate or block size, the number of channels was
861 incorrectly set to two. This caused silence in Cubase 5.
862 - save engine type (gig, sfz or sf2) in plugin state
863 - VST: when opening Fantasia, look for both 32 and 64 bit Java on
864 64 bit Windows

874 loaded a second time (this time it's for Linux and Mac, previous
875 similar fix was for Windows)
876 - thread safety fixes for the instrument loading thread
877 - LV2: use the new lv2 package if present
878 - VST: try to open Fantasia automatically on Linux and Mac too (on
879 Linux, the Fantasia jar should be placed in <prefix>/share/java)

881 - DSSI bugfix: it wasn't possible to change engine type. The MIDI
882 port and audio channel routing for DSSI plugins are now visible.
883 - LV2: use urid and atom extensions instead of deprecated uri-map
884 and event
885 - LV2: lv2 package 1.0 is now required to build the LV2 plugin

907 which allows to retrieve the list of CoreMIDI clients / ports and to connect
908 to them a la JACK, via the usual sampler APIs
909 - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
910 the driver will automatically connect to other CoreMIDI clients' ports
911 (e.g. external MIDI devices being attached to the Mac)
912 - added support for MIDI note on velocity filter
913 - CoreMIDI: fixed memory deallocation error
914 - Fixed variable underflow in VirtualMidiDevice, which caused graphical
915 virtual keyboards in frontends / instrument editors being stuck.
916 - Bugfix in VirtualMidiDevice: process note on with velocity 0 as note off.

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

1035 "gig_set_dim_zone()" now also accept an array of event IDs as argument
1036 (i.e. return value of new script function "by_marks()").
1037 - Pass/preserve polyphonic variable data from respective "note" event
1038 handler to "release" event handler.
1039 - Fixed crash when using built-in script function "by_marks()".
1040

1045 channel to a different engine type
1046 - fixed crash when deleting a sampler channel or changing engine
1047 type while an instrument load was in progress
1048 - bugfix: playing a note while changing the instrument could cause
1049 a crash, or give "Handing back unknown region" error messages
1050 - bugfix: calling SET VOICES (which Fantasia does on start and
1051 refresh) could cause instruments to be unloaded
1052 - Mac OS X: fixed name collision of enum in EffectControl and
1053 wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
1054 - Mac OS X: fixed hanging threads
1055 - Windows: disabled the previous thread fix on non-Mac systems, as
1056 it caused hanging threads on Windows
1057 - Fixed possible crashes due to corrupted MIDI/audio device list
1058 after MIDI/audio device creation failure
1059 - When creating MIDI instrument map entries with "PERSISTENT" type, the
1060 instruments were uselessly precached with zero samples, however it still
1061 took the full preloading time and on 1st program change the respective
1062 instrument was completely reloaded again.
1063 - fixed handling of rapid bank select and program change messages
1064 sent to the same sampler channel (patch from the Open Octave
1065 project, slightly adjusted)
1066 - fixed crash when trying to create an effect instance with controls
1067 which min and/or max values depend on the sample rate

1081 - fixed erroneous error message piping in VoiceBase.h
1082 (labelled "Disk stream not available in time")
1083 - Update effects on sample rate & period size changes (to avoid
1084 crashes and noise on such transitions).
1085 - ignore missing LADSPA paths without ignoring valid LADSPA paths
1086 (fixes #208)
1087 - Fixed bug in LSCP grammar definition which caused a statement like
1088 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1089 practically irrelevant, however it caused problems with the new LSCP
1090 shell's auto completion feature).
1091 - Fixed MIDI program change messages being ignored if quickly executed
1092 after each other (fixes #231).
1093
1094 Version 1.0.0 (31 July 2009)
1095
1096 * packaging changes:
1097 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
1098 causing e.g. the libgig test to fail when
1099 "./configure --disable-jack-driver" was used
1100 (patch by Alexis Ballier)
1101 - fixed compilation with gcc 4.3
1102 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)

1106 - fixed building with libgig installed in a non-standard directory
1107 - minor fix in configure for mmsystem.h detection on MinGW
1108 - Windows: look for editor plugins and Fantasia using base
1109 directory of liblinuxsampler dll (look in the same directory and one
1110 directory above)
1111 - configure script fix: removed unconditional use of SSE
1112 - fixed building with sqlite installed in a non-standard directory
1113 - when cross-compiling, don't try to create instruments.db
1114 - fix for new mingw-w64 version, which has usleep
1115
1116 * general changes:
1117 - bugfix: on some POSIX systems instrument editor plugins refused to
1118 load as we used a non-portable Linux specific struct field
1119 (fixes bug #70, patch by Ronald Baljeu)
1120 - fixed endless loop which occured when loading an instrument editor
1121 plugin DLL on Windows systems failed
1122 - fixed memory leaks that occurred when liblinuxsampler was unloaded
1123 - optimized the SynchronizedConfig class so it doesn't wait
1124 unnecessarily long after an update
1125 - added support for notifying instrument editors on note-on / note-off
1126 events (e.g. to highlight the pressed keys on the virtual keyboard
1127 of gigedit)
1128 - added support for triggering notes by instrument editors (see above)
1129 - be verbose on DLL load errors (on Linux)
1130 - fixed di-harmonic triangle LFO implementation (this LFO implementation
1131 is only used by very few systems, most pick the int math
1132 implementation, which is usually faster)
1133 - fixes for audio drivers with varying buffer sizes
1134 - experimental support for running LinuxSampler as a DSSI, LV2 and
1135 VST plugin
1136 - notification events for stream/voice count statistics are now sent
1137 only when there are actual changes
1138 - added memory ordering constraints to improve stability on
1139 multi-core and multi-cpu systems
1140 - maximum voices and disk streams can now be altered at runtime
1141 - fixed CPU feature detection on x86_64 (maybe fixes #108)
1142 - automatic stacktrace mechanism is now turned off by default and can
1143 be switched on by command line option "--stacktrace" (the automatic
1144 stacktrace mechanism seems to be broken on most systems at the moment)
1145 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
1146 a pointer to the launched InstrumentEditor object
1147 - added optional 3rd party user data parameter for following
1148 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
1149 InstrumentEditor::Launch(),
1150 InstrumentManager::LaunchInstrumentEditor()
1151 - theoretical fix: made SynchronizedConfig follow C++0x memory
1152 model more strictly
1153 - fixes for using large audio device buffers
1154 - Windows: add the installation directory to the DLL search path
1155 when loading an editor plugin (solves problems with VST and
1156 gigedit on systems with other GTK versions installed)
1157 - updated linuxsampler man page
1158
1159 * audio driver:
1160 - removed the nonsense audio channel constraint (which was hard coded to
1161 max. 100 audio channels) for most audio drivers
1162 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
1163 opposed to the LSCP specs
1164 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
1165 reflected the wrong value
1166 - fixed a memory management bug in ASIO driver
1167 - Makefile fix: JACK_CFLAGS wasn't used
1168 - JACK: use jack_client_open instead of the deprecated
1169 jack_client_new
1170 - added (experimental) CoreAudio driver
1171 - applied old fixes to the ASIO driver that were included in the
1172 previous binary release but accidentally never committed to CVS
1173 (fixes #117)
1174 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
1175 win64)
1176 - VST: added support for sample rate and buffer size changes
1177 - VST: close editor (Fantasia) when the VST is removed
1178 - VST: avoid opening Fantasia more than once for each VST instance
1179 - VST: export main function as "main" on Linux too (fix for
1180 energyXT)
1181 - VST: changed number of output channels from one stereo to 16
1182 stereo
1183 - added channel routing, fxsends and midi maps to the settings
1184 stored in the plugin state
1185 - performance optimization of AudioChannel::MixTo() and
1186 AudioChannel::CopyTo() methods using GCC vector exensions
1187 (if available)
1188 - ASIO fixes: avoid initializing the device twice, avoid throwing
1189 exception when getting parameters from a disconnected device
1190
1191 * MIDI driver:
1192 - added JACK MIDI driver
1193 - dispatch bank select as ordinary CC as well, the user might seriously
1194 want to (mis)use it for some purpose ("fixed" in all current MIDI
1195 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
1196 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
1197 CoreMidi or AU
1198 - fixed mingw-w64 compilation error in MME driver
1199 - made program change handling in MIDI thread real-time safe by
1200 moving the logic to a non-RT thread
1201 - fixed minor memory leak in ALSA driver
1202
1203 * instruments database:
1204 - avoid time consuming samples scanning when adding instruments
1205 to the instruments database
1206 - added support for handling lost files in the instruments database
1207 - Implemented option for adding instruments in separate directories
1208 in the instruments database
1209 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
1210 - work-around for missing fnmatch function on Windows to make
1211 instrument database compilable
1212 - added instrument database support on Windows
1213 works with both standalone mode and VST plugin.
1214 the instruments DB file is located in
1215 %USERPROFILE%\.linuxsampler\instruments.db which allows different
1216 databases for each windows user
1217 if no DB is present it automatically creates the .linuxsampler subdir
1218 and then creates an empty DB
1219 - fixed recursive import, which was broken on Windows
1220
1221 * Gigasampler format engine:
1222 - fixed a memory leak that could happen when a channel was deleted
1223 while notes were playing
1224 - made it possible to load an instrument even if the audio thread
1225 isn't running
1226 - added partial support for the "Controller Triggered" MIDI rule,
1227 enough for piano gigs with pedal noise samples
1228 - minor fix: only mark FX sends as being modified if really the
1229 respective FX send MIDI controller was used
1230 - added support for GM global device volume SysEx message
1231 (can be selected at compile time to either apply globally to the
1232 whole sampler [default] or only to the sampler channels that are
1233 connected to the respective MIDI input port the SysEx message arrived
1234 on)
1235 - bugfix: notes triggered at position 0 in the audio buffer were
1236 sometimes wrongly killed in the same buffer, causing no sound to
1237 be played
1238 - added support for chromatic / drumkit mode Roland GS Sysex message
1239 which is usally used to switch a part between chromatic sounds and
1240 drumkit sounds (as opposed to their common default setting of MIDI
1241 part 10 being a drumkit part and all other ones chromatic parts), in
1242 LS however one can switch between the first 16 MIDI instrument maps
1243 defined for the sampler
1244 - made it possible to create multiple sample channels even if the
1245 audio thread isn't running
1246 - fixed crash when removing channel with active voices (#116)
1247 - bugfix: on sample reference changes (instrument editor), only
1248 un-cache the respective sample if it's really not used by any
1249 sampler engine anymore
1250 - re-cache samples in case they were changed by an instrument editor,
1251 e.g. when a sample was added while playing (#82)
1252 - fixed hanging notes which occured when note-off event had the exact
1253 same time stamp as the voice's note-on event and occured both in the
1254 same audio fragment cycle (fixes bug #112)
1255 - added support for the "fine tune" and "pitch bend range"
1256 instrument-level gig parameters
1257 - fixed minor artifacts in pitch bend handling
1258 - added support for GS Reset SysEx message
1259 - allow gig files to use unlimited downward pitch shifting
1260 - added a limit check for upward pitch shifting
1261 - bugfix: sometimes, when playing a note twice fast, the second
1262 note was silent
1263 - fixed crash happening when a pitch bend event arrived at the
1264 same time a new instrument was loading
1265
1266 * LSCP server:
1267 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
1268 react on MIDI data arriving on certain sampler channels (so far only
1269 Note-On and Note-Off events are sent via this LSCP event)
1270 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1271 react on MIDI data arriving on certain MIDI input devices (so far only
1272 Note-On and Note-Off events are sent via this LSCP event)
1273 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
1274 SET DB_INSTRUMENT FILE_PATH
1275 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
1276 frontends to send MIDI messages to specific sampler channel
1277 - added two additional fields to GET FILE INSTRUMENT INFO command -
1278 KEY_BINDINGS and KEYSWITCH_BINDINGS
1279 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1280 was incorrect
1281 - Optimized the retrieval of the MIDI instrument mappings
1282 - added new LSCP command "SET VOICES" to globally alter the maximum
1283 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1284 be triggered respectively
1285 - added new LSCP command "SET STREAMS" to globally alter the maximum
1286 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1287 which will be triggered respectively
1288 - bugfix: retry if "select" returns EINTR (this fixes a crash when
1289 a gigedit file dialog is opened)
1290 - close all connections when LSCPServer is deleted
1291 - hard close of all sockets on exit
1292 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
1293 driver
1294
1295 * Bug fixes:
1296 - fixed a crash which occurs when removing a sampler channel waiting
1297 to start instrument loading after another channel
1298 - fixed a crash which occurs when removing a sampler channel with
1299 instrument loading in progress (bug #113)
1300 - fixed termination caused by uncaught exception when adding MIDI
1301 instrument with PERSISTENT load mode
1302 - fixed possible iterator invalidations when resetting the sampler
1303 - fixed memory leaks when issuing the following LSCP commands:
1304 GET AUDIO_OUTPUT_DRIVER INFO
1305 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
1306 GET MIDI_INPUT_DRIVER INFO
1307 GET MIDI_INPUT_DRIVER_PARAMETER INFO
1308 - fixed possible compilation error when sqlite is not present
1309 - fixed orphaned pointers when setting maximum voices limit (bug #118)
1310 - fixed crash when changing the audio output device of a sampler
1311 channel with loaded instrument and start playing notes
1312 - fixed endless loop in Engine::SuspendAll() (bug #120)
1313 - fixed a low-level atomic load function that was broken on 64-bit
1314 PowerPC, which probably could cause crashes on that platform
1315 - fixed a memory management error which could cause a crash when a
1316 plugin was unloaded
1317 - bugfix: two private structs had the same name, which could cause
1318 problems if the linker chose the wrong constructor
1319 - fixed low-level ConditionServer usage bug that caused lockups on
1320 Windows
1321
1322
1323 Version 0.5.1 (6 December 2007)
1324
1325 * packaging changes:
1326 - added autoconf checks for pthread library
1327 - added autoconf check for pthread bug found on certain NPTL-enabled
1328 glibc versions (see Gentoo bug report #194076)
1329 - added autoconf checks for MS Windows
1330
1331 * general changes:
1332 - bugfix: the thread used by an editor plugin didn't die when the
1333 editor closed
1334 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1335 out all the space. operator--() did not apply size_mask after
1336 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1337 order to avoid problems with the _NonVolatileReader functions.
1338 - bugfix: Stream.h: added a missing divide by BytesPerSample in
1339 GetWriteSpace(). Since this function is currently only used in
1340 the stream's qsort() compare function, it didn't trigger any
1341 bugs.
1342 - Resampler.h, Synthesizer.h: cubic interpolation now works in
1343 24bit mode too. Faster method to read 24bit words on little
1344 endian machines (x86): replaced 3 byte reads + shifts with a 1
1345 unaligned 32bit read and shift
1346 - experimental support for MS Windows (MIDI input via MME, AUDIO
1347 output via ASIO)
1348 - made handling of SIGINT signal (Ctrl-C) a bit more robust
1349 - support for monitoring the total number of active disk streams
1350 (new LSCP commands: GET TOTAL_STREAM_COUNT,
1351 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1352
1353 * AUDIO driver:
1354 - added Windows ASIO low latency audio driver
1355
1356 * MIDI driver:
1357 - added MME Windows MIDI driver
1358
1359 * LSCP server:
1360 - added support for Windows style path / filenames, however with
1361 forward slash path separators instead of backslash
1362 (i.e. "C:/foo/bar.gig")
1363 - allow naughty liblscp to send non-string device parameters within
1364 apostrophes as well
1365 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1366 "LIST FILE INSTRUMENTS <file>" and
1367 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1368 about an arbitrary instrument file on the system where the sampler is
1369 running on
1370
1371 Version 0.5.0 (15 October 2007)
1372
1373 * packaging changes:
1374 - config.h is not going to be installed along with liblinuxsampler's
1375 API header files anymore
1376 - only the API relevant header (and source) files will be exported to
1377 the Doxygen API documentation (explicitly listed in Doxyfile.in)
1378 - added completely new XCode project files for Mac OSX which is now
1379 capable to execute our autoconf environment, thus no need anymore
1380 to maintain the compile time configuration file (osx/version.h) for
1381 OSX manually (patch by Toshi Nagata)
1382 - fixed buggy boolean --enable-foo / --disable-foo configure script
1383 parameters
1384 - global.h now only covers global definitions that are needed for the
1385 C++ API header files, all implementation internal global definitions
1386 are now in global_private.h
1387 - atomic.h is not exposed to the C++ API anymore
1388 - no need to include config.h anymore for using LS's API header files
1389 - fixed warnings in API doc generation
1390
1391 * general changes:
1392 - replaced the old, confusing MIDI program change mechanism by a
1393 flexible MIDI instrument mapper which allows to map arbitrary
1394 (MIDI bank, MIDI program) pairs with arbitrary
1395 (engine type, instrument file, file index) triplets which will be
1396 loaded on the respective channel when such MIDI program change
1397 messages arrive, beside that, each entry allows to define a life-time
1398 strategy for the instrument, so the user can define whether the
1399 instrument should i.e. be permanently loaded (to be able to switch
1400 quickly among sounds) or i.e. loaded just on demand when the
1401 respective program change arrives (to safe RAM space), as well as a
1402 global volume factor for each entry, so the user can adjust the volume
1403 dynamic of his mapped instrument collection without having to modify
1404 the instrument files, also one can manage arbitrary amount of such
1405 MIDI instrument maps and assign each sampler channel individually
1406 a certain map, so that i.e. separation of normal instruments and
1407 drumkits is possible
1408 - new notification events for tracking changes to audio/MIDI devices,
1409 MIDI instrument maps, MIDI instruments, FX sends, global volume.
1410 - sampler was limited to load max. 200 instruments in the background
1411 due to a constant size RingBuffer FIFO which is now replaced by a
1412 dynamic (unlimited) size std::list FIFO
1413 - added FX sends, these allow to route audio signals to arbitrary audio
1414 output channels for being processed by external effect processors
1415 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1416 controllers
1417 - global (sampler wide) volume can now be controlled at runtime
1418 - Implemented new, improved notification system
1419 - fixed compilation errors regarding OSX
1420 (patch by Toshi Nagata)
1421 - implemented instruments database
1422 - added support for escape sequences to the instruments database
1423 - added highly experimental support for on-the-fly instrument editing
1424 within the sampler's process (by using instrument editor plugins),
1425 you'll notice the new "Registered instrument editors:" message on
1426 startup, added a new LSCP command:
1427 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1428 to spawn a matching instrument editor for the instrument on the
1429 given sampler channel, the plugin path can be overridden at compile
1430 time with ./configure --enable-plugin-dir=/some/dir
1431 - added experimental code for synchronizing instrument editors hosted
1432 in the sampler's process to safely edit instruments while playing
1433 without a crash (hopefully) by either suspending single regions
1434 wherever possible or if unavoidable whole engine(s)
1435 - fixed several issues in fundamental "Thread" class: set scheduling
1436 policy and priority on thread level, set a minimum stack size for
1437 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1438 threads simply inherited properties of starting thread instead of
1439 setting their own policy and priority
1440 - minor fix in our automatic stack trace mechanism on crashes, the
1441 main process did not wait for the stack trace process to finish
1442 its output
1443 - fixed some minor memory leaks
1444 - reenabled assembly features support, at the moment only for
1445 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1446 - minor assembly fix in x86 features detection (don't use the PIC
1447 register, to avoid relocations in the text segment at runtime)
1448 - POSIX callback functions of Thread.h are hidden
1449
1450 * MIDI driver:
1451 - dispatch bank select (MSB and LSB) messages
1452
1453 * audio driver:
1454 - the ALSA audio output driver parameters now reflect the correct
1455 parameter value ranges for the respective selected sound card
1456 (patch by Till Wimmer, a bit fixed and extended)
1457
1458 * Gigasampler format engine:
1459 - if a filter is used and EG2 finishes before EG1, let the voice
1460 die when EG2 has finished (this fixes a problem with clicks and
1461 voice starvation for some gigs)
1462 - playback is no longer disabled during instrument loading
1463 - all notes playing on a channel that changes its instrument keep
1464 playing with the old instrument until they get a note off
1465 command
1466 - EG fix: a release value of zero could cause noises or crash
1467 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1468 - EG fine tuning: when attack is zero the EG starts at a level
1469 above max sustain level, which means that there is a decay phase
1470 even if sustain is 100%
1471 - more EG fixes: the level could sometimes go below zero and cause
1472 noises or crashes
1473 - minor fix of EGDecay (patch by Toshi Nagata)
1474 - fixed compiler error when --enable-override-filter-type was
1475 supplied to the configure script (fixes #46)
1476 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1477 instead of a fix value
1478 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1479 127 (solo mode) only kill voices if the respective mode really
1480 changed
1481
1482 * LSCP server:
1483 - fixed compile time error for old Bison versions
1484 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1485 - parser now supports extended ASCII character set
1486 (up to ASCII code 255, i.e. includes now umlauts and accents)
1487 - filename arguments in LSCP commands now allow to use escape
1488 sequences, that is directly literal as one of: \', \", \\, \n, \r,
1489 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1490 code value like \xf2) (fixes bug #24)
1491 - the following LSCP commands now also support escape sequences for at
1492 least one of their text-based parameters (i.e. name, description):
1493 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1494 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1495 "SET DB_INSTRUMENT_DIRECTORY NAME",
1496 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1497 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1498 "FIND DB_INSTRUMENT_DIRECTORIES"
1499 - returns verbose syntax errors (line and column where syntax error
1500 occured, the unexpected character and the actually expected, possible
1501 character(s), the latter only if less than 5 possibilities)
1502 - made sure that LSCP syntax is not affected by gigedit locale
1503 settings
1504 - bugfix regarding strings parameter lists: all comma separated lists
1505 of strings were treated as being one string containing commas
1506 (fixes #57)
1507
1508 * Bug fixes:
1509 - fixed crash occurring on certain LSCP scripts (Bug 39)
1510 - another thread safety fix for lscp "load engine" and "set
1511 channel audio output device"
1512 - fixed a crash which occurs when reassigning the same engine
1513 on a sampler channel with connected MIDI device
1514 - fixed a crash which occurs when changing the number of ports of a MIDI
1515 device connected to a sampler channel to number less then or equal
1516 to the index of the port to which the sampler channel is connected.
1517 - The previous bindings were not been disconnected when altering
1518 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1519 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1520 - The active stream/voice count statistic was incorrect.
1521 - notification events were not been sent for some sampler
1522 channel changes
1523 - added default min and max values to restrict the number of allowed
1524 audio output channels and MIDI input ports
1525 - the connection to the PCM interface is now closed when destroying
1526 an audio output device
1527 - files with slash in their path or filename could not be loaded
1528
1529 * test cases:
1530 - updated and fixed (haven't been touched in a while)
1531
1532 Version 0.4.0 (24 November 2006)
1533
1534 * packaging changes:
1535 - changed deprecated copyright attribute to license; added ldconfig
1536 to post-(un)install steps; added devel package for liblinuxsampler;
1537 to linuxsampler.spec (RPM)
1538 - install necessary development header files for allowing 3rd party
1539 applications to link against liblinuxsampler
1540 - liblinuxsampler's API documentation can be generated with 'make docs'
1541 (Doxygen required)
1542 - added benchmark to automatically detect the best triangle LFO
1543 implementation (currently either an integer math solution or a
1544 di-harmonic approximation), automatic detection can be overriden
1545 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1546 configure script argument though (mandatory for cross-compilation)
1547 - do not automatically pick optimized gcc flags if the user already
1548 provided some on his own (as CXXFLAGS)
1549 - added compile time option to disable processing of All-Notes-Off MIDI
1550 messages
1551 - added compile time options to allow disabling the various audio and
1552 MIDI drivers
1553 - fixed automatic GCC CPU switch detection on PPC
1554 (patch by Ebrahim Mayat)
1555
1556 * Gigasampler format engine:
1557 - extensive synthesis optimization
1558 (reimplementation of EGs and LFO(s), removed synthesis parameter
1559 prerendering and the synthesis parameter matrix in general, splitting
1560 each audio fragment into subfragments now where each subfragment uses
1561 constant pitch and filter coefficients. The volume coefficient is
1562 linearly interpolated inside a subfragment, unless
1563 --disable-interpolate-volume is set.)
1564 - fine tuning of the EG modulation parameters
1565 - improved filter cutoff calculation by adding support for the
1566 following gig parameters: Cutoff freq (used when no cutoff
1567 controller is defined), Control invert, Minimum cutoff, Velocity
1568 curve and Velocity range. The keyboard tracking now scales
1569 cutoff frequency instead of resonance.
1570 - added support for gig parameter Resonance.
1571 - fixed bug in sysex handling (patch by Juan Linietsky)
1572 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1573 which can be overridden with --enable-global-attenuation
1574 - EG fixes: made the length of "attack hold" stage more
1575 accurate. Release stage can now start before attack stage
1576 ends. Cancel release didn't work when sustain was zero. Attack
1577 time now has a minimal value to prevent clicks.
1578 - fixed pitch changes larger than one octave
1579 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1580 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1581 all modes can be altered via standard GM messages, that is CC5 for
1582 altering portamento time, CC65 for enabling / disabling portamento
1583 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1584 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1585 parameter) and crossfade
1586 - added support for the "attenuation controller threshold" gig
1587 parameter
1588 - added smoothing of volume changes caused by control change
1589 messages
1590 - sample loop parameters are now taken from the DimensionRegion
1591 instead of the wave chunk
1592 - fixed keyswitching for v3 gigs with a number of keyswitch splits
1593 not equal to a power of two
1594 - reimplementation of the filter algorithm. The new filter is more
1595 accurate and supports all gig filter types, including bandreject
1596 and lowpass turbo.
1597 - real support for 24 bit samples - samples are not truncated to
1598 16 bits anymore
1599 - support for aftertouch (channel pressure, not polyphonic
1600 aftertouch)
1601 - LFO1 behaviour fixed (dampening from max volume instead of
1602 amplifying from 0)
1603
1604 * LSCP server:
1605 - fixed application exit on broken pipe error (fixes bug #20)
1606 - fixed the notification messages delay due to lack of
1607 network activity (fixes bug #26)
1608 - fixed parser bug which occured on space(s) within device parameters
1609 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1610
1611 * audio driver:
1612 - added aRts audio output driver (by no means RT safe)
1613
1614 * MIDI driver:
1615 - fixed legacy sysex code which caused dispatching of MIDI SysEx
1616 messages several times instead of once
1617 - API extension for MIDI drivers which already supply exact time stamps
1618 for events (i.e. for offline rendering based MIDI drivers)
1619 - added checks for bad MIDI data
1620
1621 * linuxsampler application:
1622 - show available sampler engine types on startup
1623
1624 * general changes:
1625 - support for muting sampler channels and solo mode of the same, two new
1626 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1627 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1628 introduced for this, the behavior is the same like on a mixer console
1629 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1630 --enable-process-muted-channels which can be used to enable the
1631 processing of muted channels.
1632 - support for sostenuto pedal
1633 - support for monitoring the total number of active voices
1634 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1635 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1636 - fixed some memory management errors
1637 - fixed some concurrency problems that could lead to crashes when
1638 LSCP commands were executed
1639 - fixed crash when instrument loading failed previously on the same
1640 sampler channel (fixes bug #36)
1641
1642 Version 0.3.3 (15 July 2005)
1643
1644 * packaging changes:
1645 - fixed compilation with gcc 4.0
1646
1647 * Gigasampler format engine:
1648 - LFO preprocessing was performed even though the respective LFO was
1649 disabled by the instrument patch (minor efficiency fix)
1650 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1651 for volume ramp downs in the same fragment (needed for current voice
1652 stealing implementation) then simply inform the user with a warning
1653 about possible click sounds and reduce the volume ramp down
1654 appropriately instead of cancelling the audio device connection
1655
1656 Version 0.3.2 (24 June 2005)
1657
1658 * packaging changes:
1659 - updated autotools build files to compile on OS X
1660 (conditional compilation of CoreMIDI and MidiShare drivers)
1661 - hand-crafted assembly optimization code can be disabled with
1662 './configure --disable-asm' (definitely not recommended)
1663 - fixed 'make dist' rule to include all necessary files
1664 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1665 (due to 'dist-bzip2' automake option)
1666
1667 * Gigasampler format engine:
1668 - support for the gig parameters for "release velocity response" curves
1669 - fine tuning of the EGADSR envelope
1670 - volume of release triggered samples now depends on note-on velocity,
1671 note length and gig parameter "release trigger decay" instead of
1672 note-off velocity.
1673 - revised voice stealing
1674 (fixes crash and endless loop caused by voice stealing)
1675 - don't reset scale tuning on instrument or audio output device change
1676 - handle key group conflicts right at the beginning of each fragment
1677 instead of when the respective voice is actually launched
1678 (fixes undefined behavior if stolen voices belonged to a key group -
1679 this case was followed by a "killed voice survived" error message)
1680 - fixed minor issue with null/silence samples
1681 (those stole voices even though they don't need a voice at all which
1682 resulted in "voice stealing didn't work out" messages)
1683 - don't reset volume, pan, pitch and MIDI controller values on
1684 instrument or audio output device change
1685
1686 * LSCP server:
1687 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1688 - fixed LSCP event "CHANNEL_INFO" notification
1689 (e.g. did not notify on volume changes or MIDI program change events)
1690
1691 * linuxsampler application:
1692 - added command line parameters --lscp-addr and --lscp-port to override
1693 default IP address and port of LSCP server
1694
1695 Version 0.3.1 (24 May 2005)
1696
1697 * initial release
