NKSP VM refactoring: Renamed all methods, functions and
classes matching pattern '*ScalarNumber*' to simply '*Number*':

- Renamed classes VMScalarNumberExpr -> VMNumberExpr,
  ScalarNumberExpr -> NumberExpr, ScalarNumberVariable ->
  NumberVariable, ScalarNumberBinaryOp -> NumberBinaryOp,
  VMScalarNumberResultFunction -> VMNumberResultFunction.

- Renamed method VMExpr::asScalarNumberExpr() -> VMExpr::asNumber().

- Renamed function isScalarNumber() -> isNumber().

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
14 * Real-time instrument scripts:
15 - Added method ScriptVM::setExitResultEnabled() which allows to
16 explicitly enable the built-in exit() function to optionally accept
17 one function argument; the value of the passed exit() function
18 argument will then become available by calling
19 VMExecContext::exitResult() after script execution.
20 - 64 bit support for NKSP integer scripts variables (declare $foo).
21 - Variable names, function names and preprocessor condition names must start
22 with a regular character (a-z or A-Z); starting them with a digit or
23 underscore is not allowed.
24 - NKSP parser fix: equal comparison operator "=" and not equal comparison
25 operator "#" must only accept integer operands.
26 - NKSP language: Implemented support for standard units like Hertz, seconds,
27 Bel including support for metric unit prefixes; so one can now e.g.
28 conveniently use numbers in scripts like "5us" meaning "5 microseconds",
29 or e.g. "12kHz" meaning "12 kilo Hertz", or e.g. "-14mdB" meaning
30 "minus 14 Millidecibel", or e.g. "28c" meaning "28 cents" (for tuning).
31 - NKSP language: Introduced "final" operator "!" which is specifically
32 intended for synthesis parameter values to denote that the synthesis
33 parameter value is intended to be the "final" value for that synthesis
34 parameter that should explicitly be used by the engine and thus causing
35 the sampler engine to ignore all other modulation sources for the same
36 synthesis parameter (like e.g. LFO, EG); by simply prefixing a value,
37 variable or formula with this new "!" operator the expression is marked as
38 being "final".
39 - NKSP script editor API: Added support for detecting standard unit tokens
40 and their potential metric prefix token.
41 - NKSP language: Added support for NKSP real number literals and
42 arithmetic operations on them (e.g. "(3.9 + 2.9) / 12.3 - 42.0").
43 - NKSP language: Added support for NKSP real number (floating point) script
44 variables (declare ~foo).
45 - NKSP language: Added support for NKSP real number (floating point) array
46 script variables (declare ?foo[]).
47 - Built-in script function "message()" accepts now real number argument as
48 well.
49 - Added built-in script function "real_to_int()" and its short hand form
50 "int()" for casting from real number to integer in NKSP scripts.
51 - Added built-in script function "int_to_real()" and its short hand form
52 "real()" for casting from integer to real number in NKSP scripts.
53 - Allow built-in exit() function to potentially accept real number type
54 argument as well.
55 - Built-in script functions may have a different return type depending on
56 the arguments passed to the function.
57 - Built-in script function "abs()" optionally accepts and returns real
58 number.
59 - Built-in script functions "min()" and "max()" optionally accept real
60 number arguments and return real number as result in that case.
61 - NKSP VM API: Allow units and 'final'ness to be returned as result from
62 built-in functions (added methods VMFunction::returnUnitType() and
63 VMFunction::returnsFinal() for that purpose which must be implemented by
64 built-in function implementations).
65 - NKSP language: Allow metric unit prefixes of numeric scalar and array
66 variables to be changed freely at runtime (unlike unit types like Hz etc.
67 which are still sticky, parse-time features of variables which cannot be
68 changed at runtime for the intentional sake of determinism).
69 - NKSP language: 'final' values are prohibited for array variables for now
70 (attempt causes a parsers error).
71 - NKSP language: expressions with unit types (e.g. Hz) are prohibited for
72 conditions of runtime control structures like if(), while(), select()
73 (attempt causes a parser error).
74 - NKSP VM API: Allow built-in functions to perform their own, individual
75 parse time checks of arguments going to be passed to the function at
76 runtime (added method VMFunction::checkArgs() for that purpose).
77 - NKSP language: raise parser warning if only one operand of binary
78 operators (like logical 'or' comparison) contain a 'final' value (because
79 it would always yield in a 'final' result in such cases).
80 - NKSP language: Allow comparison (=, #, <, >, <=, >=) of values with
81 different metric unit prefixes, which will behave as expected (e.g.
82 result of expression '1000us < 2ms' is true).
83 - NKSP language: Allow adding values with different metric unit prefixes
84 (e.g. result of expression '100Hz + 5kHz' is '5100Hz').
85 - NKSP language: Allow subtracting values with different metric unit
86 prefixes (e.g. result of expression '1ms - 20us' is '980us').
87 - NKSP language: Allow multiplying with any metric unit prefixes
88 (e.g. result of expression '2k * 3ms' is '6s'), however multiplications
89 with unit types on both sides (e.g. '2s * 2s') is still prohibited since
90 we don't have any considerable practical use for a term like '4s^2'
91 (hence any attempt multiplying two unit types still causes parser error).
92 - NKSP language: Allow dividing by any metric unit prefixes and allow
93 division of same unit type on both sides (e.g. expression '8kHz / 1000Hz'
94 yields in unit free result '8'). So this is now a way to cast units away
95 e.g. for passing the result to other expressions, certain function calls
96 or variables which are not accepting any units (or that specific unit).
97 - NKSP language: integer arrays and real number arrays can now be converted
98 to strings (e.g. for dumping their content with message() calls for
99 script debugging purposes).
100 - NKSP language: expressions and variables with units are now correctly
101 casted to strings (e.g. with message() calls).
102 - NKSP language: comparing real numbers for equalness (e.g. '~foo = 3.1') or
103 unequalness (e.g. '~foo # 3.1') is now less strict and takes the expected
104 floating point tolerances into account.
105 - NKSP VM API: Added methods VMScalarNumberExpr::evalCastInt() and
106 VMScalarNumberExpr::evalCastReal().
107 - NKSP VM API: Added base class 'VMNumberArrayExpr' for classes
108 'VMIntArrayExpr' and 'VMRealArrayExpr'.
109 - NKSP VM API: replaced all unitPrefix() (parse time) methods by
110 unitFactor() (runtime) methods.
111 - Built-in function "exit()" supports now returning units and 'final'ness
112 for test cases.
113 - The following built-in functions support now units as well: "abs()",
114 "random()", "inc()", "dec()", "in_range()", "min()", "max()",
115 "real_to_int()", "int()", "int_to_real()" and "real()".
116 - Built-in functions "array_equal()", "search()" and "sort()" support now
117 real number arrays (correctly) as well.
118 - Added individual parse time checks of arguments to be passed to built-in
119 functions "random()", "inc()", "dec()", "in_range()", "min()", "max()",
120 "array_equal()" and "search()" specific for their individual purposes.
121 - NKSP VM refactoring: Renamed all methods, functions and classes matching
122 pattern *ScalarNumber* to simply *Number* (that is i.e. classes
123 VMScalarNumberExpr -> VMNumberExpr, ScalarNumberExpr -> NumberExpr,
124 ScalarNumberVariable -> NumberVariable, ScalarNumberBinaryOp ->
125 NumberBinaryOp, VMScalarNumberResultFunction -> VMNumberResultFunction,
126 method VMExpr::asScalarNumberExpr() -> VMExpr::asNumber(), function
127 isScalarNumber() -> isNumber()).
128
129 * test cases:
130 - Fixed compiler errors in test cases.
131 - Updated README for how to compile & run test cases.
132 - Updated test case
133 MutexTest::testDoubleLockStillBlocksConcurrentThread() to latest
134 expected behaviour of the Mutex class implementation (recursive
135 mutex type).
136 - Added test cases for NKSP core language aspects and core built-in
137 functions.
138 - Fixed thread tests segfaulting on Linux.
139 - NKSP: Added real number test cases for built-in functions exit(),
140 int_to_real(), real(), real_to_int() and int(), as well as for the
141 plus, minus and negate language operators.
142 - Added massive amount of NKSP test cases for standard measuring units and
143 'final' operator usage cases.
144 - Added NKSP test cases for (floating point tolerance aware) real number
145 equalness / unequalness comparison.
146
147 Version 2.1.1 (27 Jul 2019)
148
149 * Real-time instrument scripts:
150 - Fixed behavior of built-in NKSP functions change_sustain(),
151 change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain()
152 and change_cutoff_release().
153
154 * general changes:
155 - Only play release trigger samples on sustain pedal up if this behaviour
156 was explicitly requested by the instrument (otherwise only on note-off).
157 - Fixed compiler warnings.
158 - Fixed compilation error when cross-compiling to Mac.
159 - FX Sends: Provide more useful error messages on routing problems
160 (see bug #169).
161 - LSCP doc: Be more clear describing the two distinct approaches
162 of using external vs. internal effects (see bug #169).
163 - "optional" class: Fixed comparison operators.
164
165 * Gigasampler/GigaStudio format engine:
166 - Format extension: If requested by instrument then don't play release
167 trigger sample on note-off events.
168
169 * SFZ format engine:
170 - Fixed memory leak when releasing samples
171 (fixes bug #307, patch by Jacek Roszkowski)
172 - Fixed potential crash when a sample is shared by more than one region
173 (fixes bug #308, patch by Jacek Roszkowski).
174 - Opcode 'sample': Added support for built-in sample '*silence'
175 (fixes bug #310, patch by Jacek Roszkowski).
176
177 Version 2.1.0 (25 Nov 2017)
178
179 * SFZ format engine:
180 - added support for <global>, <master> and #define (patch by Alby M)
181 - Removed code duplication in SFZ file loading code.
182 - Added support for sfz extension opcode 'script' which may be used to
183 load real-time instrument script file (NKSP script language).
184 - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
185 - Fixed unintended volume fade-in of voices under certain conditions.
186 - sfz parser: allow missing space between header and opcode
187
188 * Gigasampler/GigaStudio format engine:
189 - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
190 cutoff settings.
191 - Got rid of resembling an ancient GSt misbehavior which did not pitch at
192 all if an up-pitch of more than 40 semi tones was requested (I don't
193 think there is any stock gig sound that requires this behavior to
194 resemble its original sound).
195 - Added support for controlling whether the individual EGADSR stages may
196 be aborted (as LinuxSampler extension to the original GigaStudio 4
197 format).
198
199 * general changes:
200 - fixed printf type errors (mostly in debug messages)
201 - use unique_ptr instead of auto_ptr when building with C++11
202 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
203 allowing to sort data efficiently in real-time safe manner.
204 - RTList class: added methods for moving/inserting elements to arbitrary
205 position within a list.
206 - RTList class: added method fromPtr() for creating an Iterator object from
207 a raw element pointer.
208 - Attempt to partly fix resetting engine channels vs. resetting engine, an
209 overall cleanup of the Reset*(), ConnectAudioDevice(),
210 DisconnectAudioDevice() API methods would still be desirable though,
211 because the current situation is still inconsistent and error prone.
212 - Active voices are now internally grouped to "Note" objects, instead of
213 being directly assigned to a keyboard key. This allows more fine graded
214 processing of voices, which is i.e. required for certain instrument
215 script features.
216 - Fix: Release trigger voices were not spawned on sustain pedal up
217 (CC #64) events.
218 - Fix: Release trigger voices can now also distinguish correctly between
219 note-off and sustain pedal up events.
220 - All engines: Increased ramp speed of volume smoother and pan smoother
221 (while slow rate of crossfade smoother is preserved) to allow quick
222 volume and pan changes by instrument scripts for instance.
223 - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
224 properly and thus were ignored for certain uses.
225 - Added new C++ API method
226 VirtualMidiDevice::SendChannelPressureToSampler().
227 - windows, 32-bit: fixed potential crashes by making sure the stack in
228 sub threads is 16-byte aligned
229 - fixed numerous compiler warnings
230 - Fixed invalid (note-on) event ID being assigned to new Note objects.
231 - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
232 fixes potential undefined behavior.
233 - Fixed Note object leak when triggering notes on keys which did not
234 have a valid sample mapped (fixes bug #252).
235 - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
236 - linuxsampler binary fix: option --create-instruments-db ignored
237 subsequent optional argument due to glibc's implementation oddity
238 which expects a "=" sign, but no space between them.
239
240 * packaging changes:
241 - removed unnecessary dependency to libuuid
242 (originated by libgig's usage of it)
243 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
244 auto detect whether it (sh/c)ould output its messages in color.
245 - Debian: Fixed packaging error about invalid "Source-Version"
246 substitution variable.
247 - Debian: Raised Debian compatibility level to Debian 9 "Stretch".
248 - Debian: Added build dependency to libsqlite3-dev for building
249 linuxsampler with instruments DB support.
250
251 * Real-time instrument scripts:
252 - Implemented scheduler for delayed MIDI events and for suspended scripts.
253 - Built-in script function "wait()": implemented support for function's
254 "duration-us" argument, thus scripts using this function are now
255 correctly resumed after the requested amount of microseconds.
256 - Built-in script function "play_note()": implemented support for
257 function's "duration-us" argument, thus notes triggered with this
258 argument are now correctly released after the requested amount of
259 microseconds.
260 - Fix: script events were not cleared when engine channel was reset,
261 potentially causing undefined behavior.
262 - Fixed crash which happened when trying to reference an undeclared
263 variable.
264 - Built-in script function "play_note()": Added support for passing
265 special value -1 for "duration-us" argument, which will cause the
266 triggered note to be released once the original note was released.
267 - Instrument script classes now exported with the liblinuxsampler C++ API.
268 - Added new API method ScriptVM::syntaxHighlighting() which provides
269 a convenient syntax highlighting backend for external instrument
270 script editor applications.
271 - Added new C++ API class "ScriptVMFactory".
272 - Extended parser issues to provide not only first line and first
273 column, but also last line and last column of issue (thus marking
274 the precise span of the issue within the source code).
275 - Reload script automatically after being modified by an instrument
276 editor.
277 - NKSP language grammar correction: allow empty event handler bodies
278 like "on note end on".
279 - Implemented built-in script function "change_vol()".
280 - Implemented built-in script function "change_tune()".
281 - Implemented built-in script function "change_pan()".
282 - Implemented built-in script function "change_cutoff()".
283 - Implemented built-in script function "change_reso()".
284 - Implemented built-in script function "event_status()".
285 - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
286 "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
287 "event_status()" function.
288 - NKSP language: Added support for bitwise operators ".or.", ".and."
289 and ".not.".
290 - NKSP language scanner: Fixed IDs matching to require at least one
291 character (i.e. when matching function names or variable names).
292 - NKSP language scanner: disabled unusued rules.
293 - Fixed behavior of play_note() and note_off() functions which must
294 be distinguished engine internally from "real" MIDI note on/off
295 events in order to avoid misbehaviors like hanging notes.
296 - Implemented built-in script variable "$KSP_TIMER".
297 - Implemented built-in script variable "$NKSP_REAL_TIMER".
298 - Implemented built-in script variable "$NKSP_PERF_TIMER".
299 - Implemented built-in script variable "$ENGINE_UPTIME".
300 - Implemented built-in script function "inc()".
301 - Implemented built-in script function "dec()".
302 - NKSP language fix: division expressions were evaluated too often.
303 - NKSP language fix: string concatenation operator was right
304 associative instead of left (to right).
305 - NKSP language correction: allow empty statements in entire language
306 (i.e. "if end if").
307 - Implemented built-in script function "stop_wait()".
308 - Implemented built-in script variable "$NI_CALLBACK_ID".
309 - Implemented built-in script variable "$NI_CALLBACK_TYPE".
310 - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
311 - Added support for read-only built-in variables (respectively
312 handled by the script parser).
313 - Added built-in script constant "$NI_CB_TYPE_INIT".
314 - Added built-in script constant "$NI_CB_TYPE_NOTE".
315 - Added built-in script constant "$NI_CB_TYPE_RELEASE".
316 - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".
317 - NKSP Language: Added support for user defined script functions.
318 - Implemented built-in script function "change_attack()".
319 - Implemented built-in script function "change_decay()".
320 - Implemented built-in script function "change_release()".
321 - Fixed all change_*() built-in script functions to apply their
322 synthesis parameter changes immediately in case the respective note
323 was triggered at the same time, instead of scheduling the parameter
324 change, especially because it would cause some parameter types's
325 changes either to be ramped (i.e. change_vol()) or other types even
326 to have not effect at all (i.e. change_attack()).
327 - Implemented built-in script function "sh_left()".
328 - Implemented built-in script function "sh_right()".
329 - Implemented built-in script function "min()".
330 - Implemented built-in script function "max()".
331 - NKSP Fix: "init" event handler was not always executed when a script
332 was loaded.
333 - NKSP built-in wait() script function: abort script execution if
334 a negative or zero wait time was passed as argument (since this is
335 a common indication of a bug either of the script or even of the
336 engine, which could lead to RT instability or even worse).
337 - ScriptVM: Implemented automatic suspension of RT safety
338 threatening scripts.
339 - Provide more user friendly error messages on syntax errors.
340 - Fixed NKSP parser warning "Not a statement" when assigning an
341 initializer list to an array variable.
342 - Implemented built-in script array variable "%ALL_EVENTS".
343 - Implemented built-in script function "in_range()".
344 - Implemented built-in script function "change_amp_lfo_depth()".
345 - Implemented built-in script function "change_amp_lfo_freq()".
346 - Implemented built-in script function "change_pitch_lfo_depth()".
347 - Implemented built-in script function "change_pitch_lfo_freq()".
348 - Implemented built-in script function "change_vol_time()".
349 - Implemented built-in script function "change_tune_time()".
350 - Implemented built-in script function "fade_in()".
351 - Implemented built-in script function "fade_out()".
352 - Fixed acceptance of wrong data type of parameters passed to built-in
353 script functions "change_vol()", "change_tune()", "change_pan()",
354 "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
355 "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
356 "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
357 - Added built-in script function "get_event_par()" and implemented some
358 of its possible parameter selections.
359 - Added built-in script function "set_event_par()" and implemented some
360 of its possible parameter selections.
361 - Fixed a bunch of scheduler time related bugs.
362 - Fixed polyphonic variables not being reset to zero after usage.
363 - Built-in "ignore_event()" function: argument is now optional, like with
364 built-in function "ignore_controller()".
365 - Implemented built-in script function "change_velo()".
366 - Implemented built-in script function "change_note()".
367 - Adjusted behavior of "change_vol()" and "change_tune()" to a more
368 intuitive behavior if used in combination with "change_vol_time()" or
369 "change_tune_time()" respectively: now tuning/volume changes are only
370 assigned (without delay) immediately to a new note if the respective
371 timing function has not been called before, otherwise the volume/tuning
372 changes are automatically faded (before, only the event's time stamp was
373 relevant).
374 - Implemented built-in script function "array_equal()".
375 - Implemented built-in script function "search()".
376 - Implemented built-in script function "sort()".
377 - NKSP Fix: Never suspend "init" event handlers.
378 - Implemented built-in script function "same_region()" (currently only
379 available for gig format engine).
380 - Added built-in script constant "$NKSP_LINEAR".
381 - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
382 - Implemented built-in script function "change_vol_curve()".
383 - Implemented built-in script function "change_tune_curve()".
384 - built-in "play_note()" function now supports a sample playback start
385 offset with argument 3, where special value -1 means to use the regular
386 sample offset as defined by the instrument file.
387 - Built-in array variable %KEY_DOWN[] is now a read-only variable.
388 - Built-in variable $EVENT_NOTE is now a read-only variable.
389 - Built-in variable $EVENT_VELOCITY is now a read-only variable.
390 - built-in "play_note()" function now accepts -2 for its fourth argument
391 (note duration) which means the life time of the note shall be sticked
392 to the requested note number of argument 1.
393 - Fix: built-in "play_note()" function now returns 0 as result value if
394 -1 was passed for its fourth argument (note duration) and the respective
395 parent note is already gone.
396 - Implemented built-in script function "change_play_pos()".
397 - NKSP language: Added support for user declared const array variables.
398 - NKSP language: Raise parser warning if array variable is accessed with
399 an index that exceeds the array's size.
400 - NKSP language fix: Unknown characters were not handled correctly.
401 - NKSP language: Added support for "synchronized .. end synchronized"
402 code blocks.
403 - Implemented built-in script function "abort()" which allows to abort
404 another script handler by passing its callback ID.
405 - Fixed potential memory access bug and potential undefined behavior of
406 "init" event handlers.
407 - Print a time stamp along to each call of built-in function "message()".
408 - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
409 to retrieve all code blocks filtered out by the preprocessor.
410 - Added built-in script function "fork()".
411 - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
412 - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
413 - Fixed potential crash when accessing dynamic built-in array variables.
414 - Added built-in script function "callback_status()".
415 - Added built-in constant $CALLBACK_STATUS_TERMINATED.
416 - Added built-in constant $CALLBACK_STATUS_QUEUE.
417 - Added built-in constant $CALLBACK_STATUS_RUNNING.
418 - Removed max. value limitation of built-in functions "change_attack()",
419 "change_decay()" and "change_release()" to i.e. allow passing 2000000
420 for doubling the respective time.
421 - NKSP script editor syntax highlighting API: Fixed app termination due
422 to a lexer start condition stack underrun.
423 - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
424 USE_CODE_IF_NOT() preprocessor statements.
425 - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
426 can be set to disable all subsequent built-in "message()" function calls
427 on preprocessor level.
428 - Implemented built-in script function "change_sustain()".
429 - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
430 to avoid the editor app to crash on ill-formed text input.
431 - Added built-in script function "change_pan_time()".
432 - Added built-in script function "change_pan_curve()".
433 - Added built-in script function "change_cutoff_attack()".

489
490 * general changes:
491 - Refactoring: moved the independent code from
492 the Gigasampler format engine to base classes
493 - command line option '--profile' is currently disabled, since the
494 respective profiling code is currently broken
495 - Introduced support for optional environment variable
496 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
497 where the sampler shall look for instrument editor plugins
498 (patch by Luis Garrido, slightly modified).
499 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
500 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
501 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
502 note (in this implementation of the sampler its simply hard routed to
503 the 1st effect send of the sampler channel, no matter what the actual
504 effect type is)
505 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
506 note (in this implementation of the sampler its simply hard routed to
507 the 2nd effect send of the sampler channel, no matter what the actual
508 effect type is)
509 - implemented support for internal LADSPA effects
510 - raised limit of program change queue from 100 to 512
511 (as suggested by Alex Stone)
512 - implemented sine LFO, pulse LFO and saw LFO
513 - experimental support for per voice equalization
514 - added command line option --exec-after-init
515 - Introduced new C++ API method:
516 EngineChannel::InstrumentFileName(int index)
517 allowing to retrieve the whole list of files used for the loaded
518 instrument on an engine channel (a.k.a. part). Some GigaStudio
519 instruments for example are splitted over several files like
520 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
521 - Added new C++ API method Sampler::GetGlobalMaxVoices().
522 - Added new C++ API method Sampler::GetGlobalMaxStreams().
523 - Added new C++ API method Sampler::SetGlobalMaxVoices().
524 - Added new C++ API method Sampler::SetGlobalMaxStreams().
525 - Various "const" and "restrict" optimizations.
526 - all engines: add pan CC value to instrument pan parameter before
527 applying panning, instead of using two separate pan functions in
528 series (#182)
529 - added a lock guard class for exception safe mutex handling and
530 used it everywhere appropriate
531 - Immediately apply scale tuning changes to active voices.
532 - Exposed scale tuning to C++ API (along to the already existing standard
533 SysEx way).
534 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
535 and broken for ppc64. (Seq_cst loads and stores are actually not
536 used in LS, so the bug wasn't noticable.)
537 - lsatomic.h: added ARMv7 support
538 - Added support for multiple MIDI input ports per sampler channel (and
539 added various new C++ methods for this new feature / design change, old
540 C++ API methods for managing SamplerChannel's MIDI inputs are now marked
541 as deprecated but are still there and should provide full behavior
542 backward compatibility).
543 - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
544 unsafe and caused compilation error with clang 2.x).
545 - Bugfix: only process the latest MIDI program change event.
546 - Introducing the LSCP shell, which provides convenient control of the
547 sampler from the command line by providing LSCP aware features.
548 - VirtualMidiDevice: Added support for program change.
549 - VirtualMidiDevice: Added support for bank select (MSB & LSB).
550 - VirtualMidiDevice: Added support for pitch bend.
551 - Aftertouch: extended API to explicitly handle channel pressure and
552 polyphonic key pressure events (so far polyphonic pressure was not
553 supported at all, and channel pressure was rerouted as CC128 but not
554 used so far).
555 - Added initial support for real-time instrument scripts. The script VM
556 code is shared by all sampler engine implemementations, however only the
557 gig file format currently provides support for storing instrument scripts
558 (as LinuxSampler extension to the original GigaStudio 4 format).
559
560 * Gigasampler format engine:
561 - implemented the "round robin keyboard" dimension
562 - fixed round robin and random dimensions for cases when number of
563 dimension zones is not a power of two

565 key
566 - bugfix: pitch LFO controller "internal+aftertouch" was broken
567 - bugfix: filter keyboard tracking was broken
568 - filter performance fix (an unnecessary copy was made of the
569 filter parameters in each sub fragment)
570 - handle special case when pan parameter in gig file has max or
571 min value
572 - Exclusive Groups: don't ever stop voices of the same note,
573 doesn't sound naturally with a drumkit
574 - fixed EG1 modulation when attack or release is zero
575 - Fixed support for 'aftertouch' attenuation controller.
576 - Fixed crash that happened with velocity split sounds under certain
577 conditions (see also previous commit on libgig).
578 - fixed behaviour of filter LFO
579
580 * SFZ format engine:

610 - added support for loop_mode=one_shot
611 - fixed playback of 16 bit wav files on big endian CPUs
612 - added support for Ogg Vorbis sample files
613 - use loop markers from sample file if loop_start and loop_end are
614 not set in sfz file

757 - VST bugfix: If the host called resume() before and after
758 changing sample rate or block size, the number of channels was
759 incorrectly set to two. This caused silence in Cubase 5.
760 - save engine type (gig, sfz or sf2) in plugin state
761 - VST: when opening Fantasia, look for both 32 and 64 bit Java on
762 64 bit Windows

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

939 * Bug fixes:
940 - Fixed crash which may occur when MIDI key + transpose is out of range
941 - minor valgrind fixes
942 - fixed crash which occurred when changing an already deployed sampler
943 channel to a different engine type
944 - fixed crash when deleting a sampler channel or changing engine
945 type while an instrument load was in progress
946 - bugfix: playing a note while changing the instrument could cause
947 a crash, or give "Handing back unknown region" error messages
948 - bugfix: calling SET VOICES (which Fantasia does on start and
949 refresh) could cause instruments to be unloaded
950 - Mac OS X: fixed name collision of enum in EffectControl and
951 wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
952 - Mac OS X: fixed hanging threads
953 - Windows: disabled the previous thread fix on non-Mac systems, as
954 it caused hanging threads on Windows
955 - Fixed possible crashes due to corrupted MIDI/audio device list
956 after MIDI/audio device creation failure
957 - When creating MIDI instrument map entries with "PERSISTENT" type, the
958 instruments were uselessly precached with zero samples, however it still
959 took the full preloading time and on 1st program change the respective
960 instrument was completely reloaded again.
961 - fixed handling of rapid bank select and program change messages
962 sent to the same sampler channel (patch from the Open Octave
963 project, slightly adjusted)
964 - fixed crash when trying to create an effect instance with controls
965 which min and/or max values depend on the sample rate

978 playing a note in a key group
979 - fixed erroneous error message piping in VoiceBase.h
980 (labelled "Disk stream not available in time")
981 - Update effects on sample rate & period size changes (to avoid
982 crashes and noise on such transitions).
983 - ignore missing LADSPA paths without ignoring valid LADSPA paths
984 (fixes #208)
985 - Fixed bug in LSCP grammar definition which caused a statement like
986 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
987 practically irrelevant, however it caused problems with the new LSCP
988 shell's auto completion feature).
989 - Fixed MIDI program change messages being ignored if quickly executed
990 after each other (fixes #231).
991
992 Version 1.0.0 (31 July 2009)
993
994 * packaging changes:
995 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
996 causing e.g. the libgig test to fail when
997 "./configure --disable-jack-driver" was used
998 (patch by Alexis Ballier)
999 - fixed compilation with gcc 4.3
1000 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)

1004 - fixed building with libgig installed in a non-standard directory
1005 - minor fix in configure for mmsystem.h detection on MinGW
1006 - Windows: look for editor plugins and Fantasia using base
1007 directory of liblinuxsampler dll (look in the same directory and one
1008 directory above)
1009 - configure script fix: removed unconditional use of SSE
1010 - fixed building with sqlite installed in a non-standard directory
1011 - when cross-compiling, don't try to create instruments.db
1012 - fix for new mingw-w64 version, which has usleep
1013
1014 * general changes:
1015 - bugfix: on some POSIX systems instrument editor plugins refused to
1016 load as we used a non-portable Linux specific struct field
1017 (fixes bug #70, patch by Ronald Baljeu)
1018 - fixed endless loop which occured when loading an instrument editor
1019 plugin DLL on Windows systems failed
1020 - fixed memory leaks that occurred when liblinuxsampler was unloaded
1021 - optimized the SynchronizedConfig class so it doesn't wait
1022 unnecessarily long after an update
1023 - added support for notifying instrument editors on note-on / note-off
1024 events (e.g. to highlight the pressed keys on the virtual keyboard
1025 of gigedit)
1026 - added support for triggering notes by instrument editors (see above)
1027 - be verbose on DLL load errors (on Linux)
1028 - fixed di-harmonic triangle LFO implementation (this LFO implementation
1029 is only used by very few systems, most pick the int math
1030 implementation, which is usually faster)
1031 - fixes for audio drivers with varying buffer sizes
1032 - experimental support for running LinuxSampler as a DSSI, LV2 and
1033 VST plugin
1034 - notification events for stream/voice count statistics are now sent
1035 only when there are actual changes
1036 - added memory ordering constraints to improve stability on
1037 multi-core and multi-cpu systems
1038 - maximum voices and disk streams can now be altered at runtime
1039 - fixed CPU feature detection on x86_64 (maybe fixes #108)
1040 - automatic stacktrace mechanism is now turned off by default and can
1041 be switched on by command line option "--stacktrace" (the automatic
1042 stacktrace mechanism seems to be broken on most systems at the moment)
1043 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
1044 a pointer to the launched InstrumentEditor object
1045 - added optional 3rd party user data parameter for following
1046 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
1047 InstrumentEditor::Launch(),
1048 InstrumentManager::LaunchInstrumentEditor()
1049 - theoretical fix: made SynchronizedConfig follow C++0x memory
1050 model more strictly
1051 - fixes for using large audio device buffers
1052 - Windows: add the installation directory to the DLL search path
1053 when loading an editor plugin (solves problems with VST and
1054 gigedit on systems with other GTK versions installed)
1055 - updated linuxsampler man page
1056
1057 * audio driver:
1058 - removed the nonsense audio channel constraint (which was hard coded to
1059 max. 100 audio channels) for most audio drivers
1060 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
1061 opposed to the LSCP specs
1062 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
1063 reflected the wrong value
1064 - fixed a memory management bug in ASIO driver
1065 - Makefile fix: JACK_CFLAGS wasn't used
1066 - JACK: use jack_client_open instead of the deprecated
1067 jack_client_new
1068 - added (experimental) CoreAudio driver
1069 - applied old fixes to the ASIO driver that were included in the
1070 previous binary release but accidentally never committed to CVS
1071 (fixes #117)
1072 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
1073 win64)
1074 - VST: added support for sample rate and buffer size changes
1075 - VST: close editor (Fantasia) when the VST is removed
1076 - VST: avoid opening Fantasia more than once for each VST instance
1077 - VST: export main function as "main" on Linux too (fix for
1078 energyXT)
1079 - VST: changed number of output channels from one stereo to 16
1080 stereo
1081 - added channel routing, fxsends and midi maps to the settings
1082 stored in the plugin state
1083 - performance optimization of AudioChannel::MixTo() and
1084 AudioChannel::CopyTo() methods using GCC vector exensions
1085 (if available)
1086 - ASIO fixes: avoid initializing the device twice, avoid throwing
1087 exception when getting parameters from a disconnected device
1088
1089 * MIDI driver:
1090 - added JACK MIDI driver
1091 - dispatch bank select as ordinary CC as well, the user might seriously
1092 want to (mis)use it for some purpose ("fixed" in all current MIDI
1093 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
1094 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
1095 CoreMidi or AU
1096 - fixed mingw-w64 compilation error in MME driver
1097 - made program change handling in MIDI thread real-time safe by
1098 moving the logic to a non-RT thread
1099 - fixed minor memory leak in ALSA driver
1100
1101 * instruments database:
1102 - avoid time consuming samples scanning when adding instruments
1103 to the instruments database
1104 - added support for handling lost files in the instruments database
1105 - Implemented option for adding instruments in separate directories
1106 in the instruments database
1107 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
1108 - work-around for missing fnmatch function on Windows to make
1109 instrument database compilable
1110 - added instrument database support on Windows
1111 works with both standalone mode and VST plugin.
1112 the instruments DB file is located in
1113 %USERPROFILE%\.linuxsampler\instruments.db which allows different
1114 databases for each windows user
1115 if no DB is present it automatically creates the .linuxsampler subdir
1116 and then creates an empty DB
1117 - fixed recursive import, which was broken on Windows
1118
1119 * Gigasampler format engine:
1120 - fixed a memory leak that could happen when a channel was deleted
1121 while notes were playing
1122 - made it possible to load an instrument even if the audio thread
1123 isn't running
1124 - added partial support for the "Controller Triggered" MIDI rule,
1125 enough for piano gigs with pedal noise samples
1126 - minor fix: only mark FX sends as being modified if really the
1127 respective FX send MIDI controller was used
1128 - added support for GM global device volume SysEx message
1129 (can be selected at compile time to either apply globally to the
1130 whole sampler [default] or only to the sampler channels that are
1131 connected to the respective MIDI input port the SysEx message arrived
1132 on)
1133 - bugfix: notes triggered at position 0 in the audio buffer were
1134 sometimes wrongly killed in the same buffer, causing no sound to
1135 be played
1136 - added support for chromatic / drumkit mode Roland GS Sysex message
1137 which is usally used to switch a part between chromatic sounds and
1138 drumkit sounds (as opposed to their common default setting of MIDI
1139 part 10 being a drumkit part and all other ones chromatic parts), in
1140 LS however one can switch between the first 16 MIDI instrument maps
1141 defined for the sampler
1142 - made it possible to create multiple sample channels even if the
1143 audio thread isn't running
1144 - fixed crash when removing channel with active voices (#116)
1145 - bugfix: on sample reference changes (instrument editor), only
1146 un-cache the respective sample if it's really not used by any
1147 sampler engine anymore
1148 - re-cache samples in case they were changed by an instrument editor,
1149 e.g. when a sample was added while playing (#82)
1150 - fixed hanging notes which occured when note-off event had the exact
1151 same time stamp as the voice's note-on event and occured both in the
1152 same audio fragment cycle (fixes bug #112)
1153 - added support for the "fine tune" and "pitch bend range"
1154 instrument-level gig parameters
1155 - fixed minor artifacts in pitch bend handling
1156 - added support for GS Reset SysEx message
1157 - allow gig files to use unlimited downward pitch shifting
1158 - added a limit check for upward pitch shifting
1159 - bugfix: sometimes, when playing a note twice fast, the second
1160 note was silent
1161 - fixed crash happening when a pitch bend event arrived at the
1162 same time a new instrument was loading
1163
1164 * LSCP server:
1165 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
1166 react on MIDI data arriving on certain sampler channels (so far only
1167 Note-On and Note-Off events are sent via this LSCP event)
1168 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1169 react on MIDI data arriving on certain MIDI input devices (so far only
1170 Note-On and Note-Off events are sent via this LSCP event)
1171 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
1172 SET DB_INSTRUMENT FILE_PATH
1173 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
1174 frontends to send MIDI messages to specific sampler channel
1175 - added two additional fields to GET FILE INSTRUMENT INFO command -
1176 KEY_BINDINGS and KEYSWITCH_BINDINGS
1177 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1178 was incorrect
1179 - Optimized the retrieval of the MIDI instrument mappings
1180 - added new LSCP command "SET VOICES" to globally alter the maximum
1181 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1182 be triggered respectively
1183 - added new LSCP command "SET STREAMS" to globally alter the maximum
1184 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1185 which will be triggered respectively
1186 - bugfix: retry if "select" returns EINTR (this fixes a crash when
1187 a gigedit file dialog is opened)
1188 - close all connections when LSCPServer is deleted
1189 - hard close of all sockets on exit
1190 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
1191 driver
1192
1193 * Bug fixes:
1194 - fixed a crash which occurs when removing a sampler channel waiting
1195 to start instrument loading after another channel
1196 - fixed a crash which occurs when removing a sampler channel with
1197 instrument loading in progress (bug #113)
1198 - fixed termination caused by uncaught exception when adding MIDI
1199 instrument with PERSISTENT load mode
1200 - fixed possible iterator invalidations when resetting the sampler
1201 - fixed memory leaks when issuing the following LSCP commands:
1202 GET AUDIO_OUTPUT_DRIVER INFO
1203 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
1204 GET MIDI_INPUT_DRIVER INFO
1205 GET MIDI_INPUT_DRIVER_PARAMETER INFO
1206 - fixed possible compilation error when sqlite is not present
1207 - fixed orphaned pointers when setting maximum voices limit (bug #118)
1208 - fixed crash when changing the audio output device of a sampler
1209 channel with loaded instrument and start playing notes
1210 - fixed endless loop in Engine::SuspendAll() (bug #120)
1211 - fixed a low-level atomic load function that was broken on 64-bit
1212 PowerPC, which probably could cause crashes on that platform
1213 - fixed a memory management error which could cause a crash when a
1214 plugin was unloaded
1215 - bugfix: two private structs had the same name, which could cause
1216 problems if the linker chose the wrong constructor
1217 - fixed low-level ConditionServer usage bug that caused lockups on
1218 Windows
1219
1220
1221 Version 0.5.1 (6 December 2007)
1222
1223 * packaging changes:
1224 - added autoconf checks for pthread library
1225 - added autoconf check for pthread bug found on certain NPTL-enabled
1226 glibc versions (see Gentoo bug report #194076)
1227 - added autoconf checks for MS Windows
1228
1229 * general changes:
1230 - bugfix: the thread used by an editor plugin didn't die when the
1231 editor closed
1232 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1233 out all the space. operator--() did not apply size_mask after
1234 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1235 order to avoid problems with the _NonVolatileReader functions.
1236 - bugfix: Stream.h: added a missing divide by BytesPerSample in
1237 GetWriteSpace(). Since this function is currently only used in
1238 the stream's qsort() compare function, it didn't trigger any
1239 bugs.
1240 - Resampler.h, Synthesizer.h: cubic interpolation now works in
1241 24bit mode too. Faster method to read 24bit words on little
1242 endian machines (x86): replaced 3 byte reads + shifts with a 1
1243 unaligned 32bit read and shift
1244 - experimental support for MS Windows (MIDI input via MME, AUDIO
1245 output via ASIO)
1246 - made handling of SIGINT signal (Ctrl-C) a bit more robust
1247 - support for monitoring the total number of active disk streams
1248 (new LSCP commands: GET TOTAL_STREAM_COUNT,
1249 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1250
1251 * AUDIO driver:
1252 - added Windows ASIO low latency audio driver
1253
1254 * MIDI driver:
1255 - added MME Windows MIDI driver
1256
1257 * LSCP server:
1258 - added support for Windows style path / filenames, however with
1259 forward slash path separators instead of backslash
1260 (i.e. "C:/foo/bar.gig")
1261 - allow naughty liblscp to send non-string device parameters within
1262 apostrophes as well
1263 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1264 "LIST FILE INSTRUMENTS <file>" and
1265 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1266 about an arbitrary instrument file on the system where the sampler is
1267 running on
1268
1269 Version 0.5.0 (15 October 2007)
1270
1271 * packaging changes:
1272 - config.h is not going to be installed along with liblinuxsampler's
1273 API header files anymore
1274 - only the API relevant header (and source) files will be exported to
1275 the Doxygen API documentation (explicitly listed in Doxyfile.in)
1276 - added completely new XCode project files for Mac OSX which is now
1277 capable to execute our autoconf environment, thus no need anymore
1278 to maintain the compile time configuration file (osx/version.h) for
1279 OSX manually (patch by Toshi Nagata)
1280 - fixed buggy boolean --enable-foo / --disable-foo configure script
1281 parameters
1282 - global.h now only covers global definitions that are needed for the
1283 C++ API header files, all implementation internal global definitions
1284 are now in global_private.h
1285 - atomic.h is not exposed to the C++ API anymore
1286 - no need to include config.h anymore for using LS's API header files
1287 - fixed warnings in API doc generation
1288
1289 * general changes:
1290 - replaced the old, confusing MIDI program change mechanism by a
1291 flexible MIDI instrument mapper which allows to map arbitrary
1292 (MIDI bank, MIDI program) pairs with arbitrary
1293 (engine type, instrument file, file index) triplets which will be
1294 loaded on the respective channel when such MIDI program change
1295 messages arrive, beside that, each entry allows to define a life-time
1296 strategy for the instrument, so the user can define whether the
1297 instrument should i.e. be permanently loaded (to be able to switch
1298 quickly among sounds) or i.e. loaded just on demand when the
1299 respective program change arrives (to safe RAM space), as well as a
1300 global volume factor for each entry, so the user can adjust the volume
1301 dynamic of his mapped instrument collection without having to modify
1302 the instrument files, also one can manage arbitrary amount of such
1303 MIDI instrument maps and assign each sampler channel individually
1304 a certain map, so that i.e. separation of normal instruments and
1305 drumkits is possible
1306 - new notification events for tracking changes to audio/MIDI devices,
1307 MIDI instrument maps, MIDI instruments, FX sends, global volume.
1308 - sampler was limited to load max. 200 instruments in the background
1309 due to a constant size RingBuffer FIFO which is now replaced by a
1310 dynamic (unlimited) size std::list FIFO
1311 - added FX sends, these allow to route audio signals to arbitrary audio
1312 output channels for being processed by external effect processors
1313 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1314 controllers
1315 - global (sampler wide) volume can now be controlled at runtime
1316 - Implemented new, improved notification system
1317 - fixed compilation errors regarding OSX
1318 (patch by Toshi Nagata)
1319 - implemented instruments database
1320 - added support for escape sequences to the instruments database
1321 - added highly experimental support for on-the-fly instrument editing
1322 within the sampler's process (by using instrument editor plugins),
1323 you'll notice the new "Registered instrument editors:" message on
1324 startup, added a new LSCP command:
1325 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1326 to spawn a matching instrument editor for the instrument on the
1327 given sampler channel, the plugin path can be overridden at compile
1328 time with ./configure --enable-plugin-dir=/some/dir
1329 - added experimental code for synchronizing instrument editors hosted
1330 in the sampler's process to safely edit instruments while playing
1331 without a crash (hopefully) by either suspending single regions
1332 wherever possible or if unavoidable whole engine(s)
1333 - fixed several issues in fundamental "Thread" class: set scheduling
1334 policy and priority on thread level, set a minimum stack size for
1335 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1336 threads simply inherited properties of starting thread instead of
1337 setting their own policy and priority
1338 - minor fix in our automatic stack trace mechanism on crashes, the
1339 main process did not wait for the stack trace process to finish
1340 its output
1341 - fixed some minor memory leaks
1342 - reenabled assembly features support, at the moment only for
1343 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1344 - minor assembly fix in x86 features detection (don't use the PIC
1345 register, to avoid relocations in the text segment at runtime)
1346 - POSIX callback functions of Thread.h are hidden
1347
1348 * MIDI driver:
1349 - dispatch bank select (MSB and LSB) messages
1350
1351 * audio driver:
1352 - the ALSA audio output driver parameters now reflect the correct
1353 parameter value ranges for the respective selected sound card
1354 (patch by Till Wimmer, a bit fixed and extended)
1355
1356 * Gigasampler format engine:
1357 - if a filter is used and EG2 finishes before EG1, let the voice
1358 die when EG2 has finished (this fixes a problem with clicks and
1359 voice starvation for some gigs)
1360 - playback is no longer disabled during instrument loading
1361 - all notes playing on a channel that changes its instrument keep
1362 playing with the old instrument until they get a note off
1363 command
1364 - EG fix: a release value of zero could cause noises or crash
1365 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1366 - EG fine tuning: when attack is zero the EG starts at a level
1367 above max sustain level, which means that there is a decay phase
1368 even if sustain is 100%
1369 - more EG fixes: the level could sometimes go below zero and cause
1370 noises or crashes
1371 - minor fix of EGDecay (patch by Toshi Nagata)
1372 - fixed compiler error when --enable-override-filter-type was
1373 supplied to the configure script (fixes #46)
1374 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1375 instead of a fix value
1376 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1377 127 (solo mode) only kill voices if the respective mode really
1378 changed
1379
1380 * LSCP server:
1381 - fixed compile time error for old Bison versions
1382 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1383 - parser now supports extended ASCII character set
1384 (up to ASCII code 255, i.e. includes now umlauts and accents)
1385 - filename arguments in LSCP commands now allow to use escape
1386 sequences, that is directly literal as one of: \', \", \\, \n, \r,
1387 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1388 code value like \xf2) (fixes bug #24)
1389 - the following LSCP commands now also support escape sequences for at
1390 least one of their text-based parameters (i.e. name, description):
1391 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1392 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1393 "SET DB_INSTRUMENT_DIRECTORY NAME",
1394 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1395 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1396 "FIND DB_INSTRUMENT_DIRECTORIES"
1397 - returns verbose syntax errors (line and column where syntax error
1398 occured, the unexpected character and the actually expected, possible
1399 character(s), the latter only if less than 5 possibilities)
1400 - made sure that LSCP syntax is not affected by gigedit locale
1401 settings
1402 - bugfix regarding strings parameter lists: all comma separated lists
1403 of strings were treated as being one string containing commas
1404 (fixes #57)
1405
1406 * Bug fixes:
1407 - fixed crash occurring on certain LSCP scripts (Bug 39)
1408 - another thread safety fix for lscp "load engine" and "set
1409 channel audio output device"
1410 - fixed a crash which occurs when reassigning the same engine
1411 on a sampler channel with connected MIDI device
1412 - fixed a crash which occurs when changing the number of ports of a MIDI
1413 device connected to a sampler channel to number less then or equal
1414 to the index of the port to which the sampler channel is connected.
1415 - The previous bindings were not been disconnected when altering
1416 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1417 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1418 - The active stream/voice count statistic was incorrect.
1419 - notification events were not been sent for some sampler
1420 channel changes
1421 - added default min and max values to restrict the number of allowed
1422 audio output channels and MIDI input ports
1423 - the connection to the PCM interface is now closed when destroying
1424 an audio output device
1425 - files with slash in their path or filename could not be loaded
1426
1427 * test cases:
1428 - updated and fixed (haven't been touched in a while)
1429
1430 Version 0.4.0 (24 November 2006)
1431
1432 * packaging changes:
1433 - changed deprecated copyright attribute to license; added ldconfig
1434 to post-(un)install steps; added devel package for liblinuxsampler;
1435 to linuxsampler.spec (RPM)
1436 - install necessary development header files for allowing 3rd party
1437 applications to link against liblinuxsampler
1438 - liblinuxsampler's API documentation can be generated with 'make docs'
1439 (Doxygen required)
1440 - added benchmark to automatically detect the best triangle LFO
1441 implementation (currently either an integer math solution or a
1442 di-harmonic approximation), automatic detection can be overriden
1443 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1444 configure script argument though (mandatory for cross-compilation)
1445 - do not automatically pick optimized gcc flags if the user already
1446 provided some on his own (as CXXFLAGS)
1447 - added compile time option to disable processing of All-Notes-Off MIDI
1448 messages
1449 - added compile time options to allow disabling the various audio and
1450 MIDI drivers
1451 - fixed automatic GCC CPU switch detection on PPC
1452 (patch by Ebrahim Mayat)
1453
1454 * Gigasampler format engine:
1455 - extensive synthesis optimization
1456 (reimplementation of EGs and LFO(s), removed synthesis parameter
1457 prerendering and the synthesis parameter matrix in general, splitting
1458 each audio fragment into subfragments now where each subfragment uses
1459 constant pitch and filter coefficients. The volume coefficient is
1460 linearly interpolated inside a subfragment, unless
1461 --disable-interpolate-volume is set.)
1462 - fine tuning of the EG modulation parameters
1463 - improved filter cutoff calculation by adding support for the
1464 following gig parameters: Cutoff freq (used when no cutoff
1465 controller is defined), Control invert, Minimum cutoff, Velocity
1466 curve and Velocity range. The keyboard tracking now scales
1467 cutoff frequency instead of resonance.
1468 - added support for gig parameter Resonance.
1469 - fixed bug in sysex handling (patch by Juan Linietsky)
1470 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1471 which can be overridden with --enable-global-attenuation
1472 - EG fixes: made the length of "attack hold" stage more
1473 accurate. Release stage can now start before attack stage
1474 ends. Cancel release didn't work when sustain was zero. Attack
1475 time now has a minimal value to prevent clicks.
1476 - fixed pitch changes larger than one octave
1477 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1478 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1479 all modes can be altered via standard GM messages, that is CC5 for
1480 altering portamento time, CC65 for enabling / disabling portamento
1481 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1482 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1483 parameter) and crossfade
1484 - added support for the "attenuation controller threshold" gig
1485 parameter
1486 - added smoothing of volume changes caused by control change
1487 messages
1488 - sample loop parameters are now taken from the DimensionRegion
1489 instead of the wave chunk
1490 - fixed keyswitching for v3 gigs with a number of keyswitch splits
1491 not equal to a power of two
1492 - reimplementation of the filter algorithm. The new filter is more
1493 accurate and supports all gig filter types, including bandreject
1494 and lowpass turbo.
1495 - real support for 24 bit samples - samples are not truncated to
1496 16 bits anymore
1497 - support for aftertouch (channel pressure, not polyphonic
1498 aftertouch)
1499 - LFO1 behaviour fixed (dampening from max volume instead of
1500 amplifying from 0)
1501
1502 * LSCP server:
1503 - fixed application exit on broken pipe error (fixes bug #20)
1504 - fixed the notification messages delay due to lack of
1505 network activity (fixes bug #26)
1506 - fixed parser bug which occured on space(s) within device parameters
1507 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1508
1509 * audio driver:
1510 - added aRts audio output driver (by no means RT safe)
1511
1512 * MIDI driver:
1513 - fixed legacy sysex code which caused dispatching of MIDI SysEx
1514 messages several times instead of once
1515 - API extension for MIDI drivers which already supply exact time stamps
1516 for events (i.e. for offline rendering based MIDI drivers)
1517 - added checks for bad MIDI data
1518
1519 * linuxsampler application:
1520 - show available sampler engine types on startup
1521
1522 * general changes:
1523 - support for muting sampler channels and solo mode of the same, two new
1524 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1525 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1526 introduced for this, the behavior is the same like on a mixer console
1527 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1528 --enable-process-muted-channels which can be used to enable the
1529 processing of muted channels.
1530 - support for sostenuto pedal
1531 - support for monitoring the total number of active voices
1532 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1533 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1534 - fixed some memory management errors
1535 - fixed some concurrency problems that could lead to crashes when
1536 LSCP commands were executed
1537 - fixed crash when instrument loading failed previously on the same
1538 sampler channel (fixes bug #36)
1539
1540 Version 0.3.3 (15 July 2005)
1541
1542 * packaging changes:
1543 - fixed compilation with gcc 4.0
1544
1545 * Gigasampler format engine:
1546 - LFO preprocessing was performed even though the respective LFO was
1547 disabled by the instrument patch (minor efficiency fix)
1548 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1549 for volume ramp downs in the same fragment (needed for current voice
1550 stealing implementation) then simply inform the user with a warning
1551 about possible click sounds and reduce the volume ramp down
1552 appropriately instead of cancelling the audio device connection
1553
1554 Version 0.3.2 (24 June 2005)
1555
1556 * packaging changes:
1557 - updated autotools build files to compile on OS X
1558 (conditional compilation of CoreMIDI and MidiShare drivers)
1559 - hand-crafted assembly optimization code can be disabled with
1560 './configure --disable-asm' (definitely not recommended)
1561 - fixed 'make dist' rule to include all necessary files
1562 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1563 (due to 'dist-bzip2' automake option)
1564
1565 * Gigasampler format engine:
1566 - support for the gig parameters for "release velocity response" curves
1567 - fine tuning of the EGADSR envelope
1568 - volume of release triggered samples now depends on note-on velocity,
1569 note length and gig parameter "release trigger decay" instead of
1570 note-off velocity.
1571 - revised voice stealing
1572 (fixes crash and endless loop caused by voice stealing)
1573 - don't reset scale tuning on instrument or audio output device change
1574 - handle key group conflicts right at the beginning of each fragment
1575 instead of when the respective voice is actually launched
1576 (fixes undefined behavior if stolen voices belonged to a key group -
1577 this case was followed by a "killed voice survived" error message)
1578 - fixed minor issue with null/silence samples
1579 (those stole voices even though they don't need a voice at all which
1580 resulted in "voice stealing didn't work out" messages)
1581 - don't reset volume, pan, pitch and MIDI controller values on
1582 instrument or audio output device change
1583
1584 * LSCP server:
1585 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1586 - fixed LSCP event "CHANNEL_INFO" notification
1587 (e.g. did not notify on volume changes or MIDI program change events)
1588
1589 * linuxsampler application:
1590 - added command line parameters --lscp-addr and --lscp-port to override
1591 default IP address and port of LSCP server
1592
1593 Version 0.3.1 (24 May 2005)
1594
1595 * initial release
