3 * general changes:
4 - Fixed compiler error in Pool.h.
5 - Fixed compiler errors in test cases.
6 - Updated README for how to compile & run test cases.
7 - Updated test case
8 MutexTest::testDoubleLockStillBlocksConcurrentThread() to latest
9 expected behaviour of the Mutex class implementation (recursive
10 mutex type).
12 Version 2.1.1 (27 Jul 2019)
14 * Real-time instrument scripts:
15 - Fixed behavior of built-in NKSP functions change_sustain(),
16 change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain()
17 and change_cutoff_release().
19 * general changes:
20 - Only play release trigger samples on sustain pedal up if this behaviour
21 was explicitly requested by the instrument (otherwise only on note-off).
22 - Fixed compiler warnings.
23 - Fixed compilation error when cross-compiling to Mac.
24 - FX Sends: Provide more useful error messages on routing problems
25 (see bug #169).
26 - LSCP doc: Be more clear describing the two distinct approaches
27 of using external vs. internal effects (see bug #169).
28 - "optional" class: Fixed comparison operators.
30 * Gigasampler/GigaStudio format engine:
31 - Format extension: If requested by instrument then don't play release
32 trigger sample on note-off events.
34 * SFZ format engine:
35 - Fixed memory leak when releasing samples
36 (fixes bug #307, patch by Jacek Roszkowski)
37 - Fixed potential crash when a sample is shared by more than one region
38 (fixes bug #308, patch by Jacek Roszkowski).
39 - Opcode 'sample': Added support for built-in sample '*silence'
40 (fixes bug #310, patch by Jacek Roszkowski).
42 Version 2.1.0 (25 Nov 2017)
44 * SFZ format engine:
45 - added support for <global>, <master> and #define (patch by Alby M)
46 - Removed code duplication in SFZ file loading code.
47 - Added support for sfz extension opcode 'script' which may be used to
48 load real-time instrument script file (NKSP script language).
49 - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
50 - Fixed unintended volume fade-in of voices under certain conditions.
51 - sfz parser: allow missing space between header and opcode
53 * Gigasampler/GigaStudio format engine:
54 - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
55 cutoff settings.
56 - Got rid of resembling an ancient GSt misbehavior which did not pitch at
57 all if an up-pitch of more than 40 semi tones was requested (I don't
58 think there is any stock gig sound that requires this behavior to
59 resemble its original sound).
60 - Added support for controlling whether the individual EGADSR stages may
61 be aborted (as LinuxSampler extension to the original GigaStudio 4
62 format).
64 * general changes:
65 - fixed printf type errors (mostly in debug messages)
66 - use unique_ptr instead of auto_ptr when building with C++11
67 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
68 allowing to sort data efficiently in real-time safe manner.
69 - RTList class: added methods for moving/inserting elements to arbitrary
70 position within a list.
71 - RTList class: added method fromPtr() for creating an Iterator object from
72 a raw element pointer.
73 - Attempt to partly fix resetting engine channels vs. resetting engine, an
74 overall cleanup of the Reset*(), ConnectAudioDevice(),
75 DisconnectAudioDevice() API methods would still be desirable though,
76 because the current situation is still inconsistent and error prone.
77 - Active voices are now internally grouped to "Note" objects, instead of
78 being directly assigned to a keyboard key. This allows more fine graded
79 processing of voices, which is i.e. required for certain instrument
80 script features.
81 - Fix: Release trigger voices were not spawned on sustain pedal up
82 (CC #64) events.
83 - Fix: Release trigger voices can now also distinguish correctly between
84 note-off and sustain pedal up events.
85 - All engines: Increased ramp speed of volume smoother and pan smoother
86 (while slow rate of crossfade smoother is preserved) to allow quick
87 volume and pan changes by instrument scripts for instance.
88 - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
89 properly and thus were ignored for certain uses.
90 - Added new C++ API method
91 VirtualMidiDevice::SendChannelPressureToSampler().
92 - windows, 32-bit: fixed potential crashes by making sure the stack in
93 sub threads is 16-byte aligned
94 - fixed numerous compiler warnings
95 - Fixed invalid (note-on) event ID being assigned to new Note objects.
96 - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
97 fixes potential undefined behavior.
98 - Fixed Note object leak when triggering notes on keys which did not
99 have a valid sample mapped (fixes bug #252).
100 - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
101 - linuxsampler binary fix: option --create-instruments-db ignored
102 subsequent optional argument due to glibc's implementation oddity
103 which expects a "=" sign, but no space between them.
105 * packaging changes:
106 - removed unnecessary dependency to libuuid
107 (originated by libgig's usage of it)
108 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
109 auto detect whether it (sh/c)ould output its messages in color.
110 - Debian: Fixed packaging error about invalid "Source-Version"
111 substitution variable.
112 - Debian: Raised Debian compatibility level to Debian 9 "Stretch".
113 - Debian: Added build dependency to libsqlite3-dev for building
114 linuxsampler with instruments DB support.
116 * Real-time instrument scripts:
117 - Implemented scheduler for delayed MIDI events and for suspended scripts.
118 - Built-in script function "wait()": implemented support for function's
119 "duration-us" argument, thus scripts using this function are now
120 correctly resumed after the requested amount of microseconds.
121 - Built-in script function "play_note()": implemented support for
122 function's "duration-us" argument, thus notes triggered with this
123 argument are now correctly released after the requested amount of
124 microseconds.
125 - Fix: script events were not cleared when engine channel was reset,
126 potentially causing undefined behavior.
127 - Fixed crash which happened when trying to reference an undeclared
128 variable.
129 - Built-in script function "play_note()": Added support for passing
130 special value -1 for "duration-us" argument, which will cause the
131 triggered note to be released once the original note was released.
132 - Instrument script classes now exported with the liblinuxsampler C++ API.
133 - Added new API method ScriptVM::syntaxHighlighting() which provides
134 a convenient syntax highlighting backend for external instrument
135 script editor applications.
136 - Added new C++ API class "ScriptVMFactory".
137 - Extended parser issues to provide not only first line and first
138 column, but also last line and last column of issue (thus marking
139 the precise span of the issue within the source code).
140 - Reload script automatically after being modified by an instrument
141 editor.
142 - NKSP language grammar correction: allow empty event handler bodies
143 like "on note end on".
144 - Implemented built-in script function "change_vol()".
145 - Implemented built-in script function "change_tune()".
146 - Implemented built-in script function "change_pan()".
147 - Implemented built-in script function "change_cutoff()".
148 - Implemented built-in script function "change_reso()".
149 - Implemented built-in script function "event_status()".
150 - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
151 "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
152 "event_status()" function.
153 - NKSP language: Added support for bitwise operators ".or.", ".and."
154 and ".not.".
155 - NKSP language scanner: Fixed IDs matching to require at least one
156 character (i.e. when matching function names or variable names).
157 - NKSP language scanner: disabled unusued rules.
158 - Fixed behavior of play_note() and note_off() functions which must
159 be distinguished engine internally from "real" MIDI note on/off
160 events in order to avoid misbehaviors like hanging notes.
161 - Implemented built-in script variable "$KSP_TIMER".
162 - Implemented built-in script variable "$NKSP_REAL_TIMER".
163 - Implemented built-in script variable "$NKSP_PERF_TIMER".
164 - Implemented built-in script variable "$ENGINE_UPTIME".
165 - Implemented built-in script function "inc()".
166 - Implemented built-in script function "dec()".
167 - NKSP language fix: division expressions were evaluated too often.
168 - NKSP language fix: string concatenation operator was right
169 associative instead of left (to right).
170 - NKSP language correction: allow empty statements in entire language
171 (i.e. "if end if").
172 - Implemented built-in script function "stop_wait()".
173 - Implemented built-in script variable "$NI_CALLBACK_ID".
174 - Implemented built-in script variable "$NI_CALLBACK_TYPE".
175 - Implemented built-in script variable "$NKSP_IGNORE_WAIT".

183 - Implemented built-in script function "change_attack()".
184 - Implemented built-in script function "change_decay()".
185 - Implemented built-in script function "change_release()".
186 - Fixed all change_*() built-in script functions to apply their
187 synthesis parameter changes immediately in case the respective note
188 was triggered at the same time, instead of scheduling the parameter
189 change, especially because it would cause some parameter types's
190 changes either to be ramped (i.e. change_vol()) or other types even
191 to have not effect at all (i.e. change_attack()).
192 - Implemented built-in script function "sh_left()".
193 - Implemented built-in script function "sh_right()".
194 - Implemented built-in script function "min()".
195 - Implemented built-in script function "max()".
196 - NKSP Fix: "init" event handler was not always executed when a script
197 was loaded.
198 - NKSP built-in wait() script function: abort script execution if
199 a negative or zero wait time was passed as argument (since this is
200 a common indication of a bug either of the script or even of the
201 engine, which could lead to RT instability or even worse).
202 - ScriptVM: Implemented automatic suspension of RT safety
203 threatening scripts.
204 - Provide more user friendly error messages on syntax errors.
205 - Fixed NKSP parser warning "Not a statement" when assigning an
206 initializer list to an array variable.

210 - Implemented built-in script function "change_amp_lfo_freq()".
211 - Implemented built-in script function "change_pitch_lfo_depth()".
212 - Implemented built-in script function "change_pitch_lfo_freq()".
213 - Implemented built-in script function "change_vol_time()".
214 - Implemented built-in script function "change_tune_time()".
215 - Implemented built-in script function "fade_in()".
216 - Implemented built-in script function "fade_out()".
217 - Fixed acceptance of wrong data type of parameters passed to built-in
218 script functions "change_vol()", "change_tune()", "change_pan()",
219 "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
220 "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
221 "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
222 - Added built-in script function "get_event_par()" and implemented some
223 of its possible parameter selections.
224 - Added built-in script function "set_event_par()" and implemented some
225 of its possible parameter selections.
226 - Fixed a bunch of scheduler time related bugs.
227 - Fixed polyphonic variables not being reset to zero after usage.
228 - Built-in "ignore_event()" function: argument is now optional, like with
229 built-in function "ignore_controller()".
230 - Implemented built-in script function "change_velo()".
231 - Implemented built-in script function "change_note()".
232 - Adjusted behavior of "change_vol()" and "change_tune()" to a more
233 intuitive behavior if used in combination with "change_vol_time()" or
234 "change_tune_time()" respectively: now tuning/volume changes are only
235 assigned (without delay) immediately to a new note if the respective
236 timing function has not been called before, otherwise the volume/tuning
237 changes are automatically faded (before, only the event's time stamp was
238 relevant).
239 - Implemented built-in script function "array_equal()".
240 - Implemented built-in script function "search()".
241 - Implemented built-in script function "sort()".
242 - NKSP Fix: Never suspend "init" event handlers.
243 - Implemented built-in script function "same_region()" (currently only
244 available for gig format engine).
245 - Added built-in script constant "$NKSP_LINEAR".
246 - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
247 - Implemented built-in script function "change_vol_curve()".
248 - Implemented built-in script function "change_tune_curve()".
249 - built-in "play_note()" function now supports a sample playback start
250 offset with argument 3, where special value -1 means to use the regular
251 sample offset as defined by the instrument file.
252 - Built-in array variable %KEY_DOWN[] is now a read-only variable.
253 - Built-in variable $EVENT_NOTE is now a read-only variable.
254 - Built-in variable $EVENT_VELOCITY is now a read-only variable.
255 - built-in "play_note()" function now accepts -2 for its fourth argument
256 (note duration) which means the life time of the note shall be sticked
257 to the requested note number of argument 1.
258 - Fix: built-in "play_note()" function now returns 0 as result value if
259 -1 was passed for its fourth argument (note duration) and the respective
260 parent note is already gone.
261 - Implemented built-in script function "change_play_pos()".
262 - NKSP language: Added support for user declared const array variables.
263 - NKSP language: Raise parser warning if array variable is accessed with
264 an index that exceeds the array's size.
265 - NKSP language fix: Unknown characters were not handled correctly.
266 - NKSP language: Added support for "synchronized .. end synchronized"
267 code blocks.
268 - Implemented built-in script function "abort()" which allows to abort
269 another script handler by passing its callback ID.
270 - Fixed potential memory access bug and potential undefined behavior of
271 "init" event handlers.
272 - Print a time stamp along to each call of built-in function "message()".
273 - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
274 to retrieve all code blocks filtered out by the preprocessor.
275 - Added built-in script function "fork()".
276 - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
277 - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
278 - Fixed potential crash when accessing dynamic built-in array variables.
279 - Added built-in script function "callback_status()".
280 - Added built-in constant $CALLBACK_STATUS_TERMINATED.
281 - Added built-in constant $CALLBACK_STATUS_QUEUE.
282 - Added built-in constant $CALLBACK_STATUS_RUNNING.
283 - Removed max. value limitation of built-in functions "change_attack()",
284 "change_decay()" and "change_release()" to i.e. allow passing 2000000
285 for doubling the respective time.
286 - NKSP script editor syntax highlighting API: Fixed app termination due
287 to a lexer start condition stack underrun.
288 - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
289 USE_CODE_IF_NOT() preprocessor statements.
290 - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
291 can be set to disable all subsequent built-in "message()" function calls
292 on preprocessor level.
293 - Implemented built-in script function "change_sustain()".
294 - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
295 to avoid the editor app to crash on ill-formed text input.
296 - Added built-in script function "change_pan_time()".
297 - Added built-in script function "change_pan_curve()".
298 - Added built-in script function "change_cutoff_attack()".

305 * Instruments DB:
306 - Fixed memory access bug of general DB access code which lead to
307 undefined behavior.
308 - Cleanup of instruments DB file creation and opening code.
309 - The instrument DB path of linuxsampler's --create-instruments-db argument
310 is now optional, if it is missing, then a default location is used.
311 - Added support for scanning SFZ (.sfz) files.
312 - Added support for scanning Sound Font (.sf2) files.
313 - Fixed undefined DB transaction behavior.
315 Version 2.0.0 (15 July 2015)
317 * packaging changes:
318 - fixed building with newer MinGW-w64
319 - Mac OS X: support the new dir for Core Audio SDK
320 - Mac OS X: fixed building outside source directory
321 - made sure all source files for hostplugins are included when
322 doing "make dist"
323 - removed empty directories left from the cvs to svn migration
324 - fixed compilation with gcc 4.6.1
325 - another "make dist" fix, for the LV2 plugin
326 - made --enable-pthread-testcancel default on Mac OS X
327 - minor Makefile fix for building lscpparser when build and source
328 directories are separate
329 - Mac OS X: made it possible to specify plugin installation dir to
330 configure
331 - Mac OS X: Makefile fix for the install-strip target
332 - fixed compilation with gcc 4.7
333 - fixed configure script error with old autoconf versions
334 - lsatomic.h: use gcc provided atomic functions if building with
335 gcc 4.7 and C++11
336 - modernized configure script
337 - fixed linkage error when building with
338 LDFLAGS="-Wl,--no-undefined" (#190)

343 - build fix: libsndfile compiler flags were missing in some
344 makefiles
345 - fix for building with bison 3.0 (#202)
346 - Mac OS X: added temporary hack allowing to spawn gigedit as callback
347 on the process's main thread
348 - fixed build error on newer MinGW
349 - support building with older jack versions
350 - support building with spaces in vst sdk path
351 - enabled automake 'subdir-objects' option and moved external
352 source references (vst, au, asio) from makefiles to cpp files,
353 in order to get rid of warnings from automake 1.14
355 * general changes:
356 - Refactoring: moved the independent code from
357 the Gigasampler format engine to base classes
358 - command line option '--profile' is currently disabled, since the
359 respective profiling code is currently broken
360 - Introduced support for optional environment variable
361 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
362 where the sampler shall look for instrument editor plugins
363 (patch by Luis Garrido, slightly modified).
364 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
365 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
366 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
367 note (in this implementation of the sampler its simply hard routed to
368 the 1st effect send of the sampler channel, no matter what the actual
369 effect type is)
370 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
371 note (in this implementation of the sampler its simply hard routed to
372 the 2nd effect send of the sampler channel, no matter what the actual
373 effect type is)
374 - implemented support for internal LADSPA effects
375 - raised limit of program change queue from 100 to 512
376 (as suggested by Alex Stone)
377 - implemented sine LFO, pulse LFO and saw LFO
378 - experimental support for per voice equalization
379 - added command line option --exec-after-init
380 - Introduced new C++ API method:
381 EngineChannel::InstrumentFileName(int index)
382 allowing to retrieve the whole list of files used for the loaded
383 instrument on an engine channel (a.k.a. part). Some GigaStudio
384 instruments for example are splitted over several files like
385 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
386 - Added new C++ API method Sampler::GetGlobalMaxVoices().
387 - Added new C++ API method Sampler::GetGlobalMaxStreams().
388 - Added new C++ API method Sampler::SetGlobalMaxVoices().
389 - Added new C++ API method Sampler::SetGlobalMaxStreams().
390 - Various "const" and "restrict" optimizations.
391 - all engines: add pan CC value to instrument pan parameter before
392 applying panning, instead of using two separate pan functions in
393 series (#182)
394 - added a lock guard class for exception safe mutex handling and
395 used it everywhere appropriate
396 - Immediately apply scale tuning changes to active voices.
397 - Exposed scale tuning to C++ API (along to the already existing standard
398 SysEx way).
399 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
400 and broken for ppc64. (Seq_cst loads and stores are actually not
401 used in LS, so the bug wasn't noticable.)
402 - lsatomic.h: added ARMv7 support
403 - Added support for multiple MIDI input ports per sampler channel (and
404 added various new C++ methods for this new feature / design change, old
405 C++ API methods for managing SamplerChannel's MIDI inputs are now marked
406 as deprecated but are still there and should provide full behavior
407 backward compatibility).
408 - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
409 unsafe and caused compilation error with clang 2.x).
410 - Bugfix: only process the latest MIDI program change event.
411 - Introducing the LSCP shell, which provides convenient control of the
412 sampler from the command line by providing LSCP aware features.
413 - VirtualMidiDevice: Added support for program change.
414 - VirtualMidiDevice: Added support for bank select (MSB & LSB).
415 - VirtualMidiDevice: Added support for pitch bend.
416 - Aftertouch: extended API to explicitly handle channel pressure and
417 polyphonic key pressure events (so far polyphonic pressure was not
418 supported at all, and channel pressure was rerouted as CC128 but not
419 used so far).
420 - Added initial support for real-time instrument scripts. The script VM
421 code is shared by all sampler engine implemementations, however only the
422 gig file format currently provides support for storing instrument scripts
423 (as LinuxSampler extension to the original GigaStudio 4 format).
425 * Gigasampler format engine:
426 - implemented the "round robin keyboard" dimension
427 - fixed round robin and random dimensions for cases when number of
428 dimension zones is not a power of two
429 - made round robin use a counter for each region instead of each
430 key
431 - bugfix: pitch LFO controller "internal+aftertouch" was broken
432 - bugfix: filter keyboard tracking was broken
433 - filter performance fix (an unnecessary copy was made of the
434 filter parameters in each sub fragment)
435 - handle special case when pan parameter in gig file has max or
436 min value
437 - Exclusive Groups: don't ever stop voices of the same note,
438 doesn't sound naturally with a drumkit
439 - fixed EG1 modulation when attack or release is zero
440 - Fixed support for 'aftertouch' attenuation controller.
441 - Fixed crash that happened with velocity split sounds under certain
442 conditions (see also previous commit on libgig).
443 - fixed behaviour of filter LFO
445 * SFZ format engine:
446 - Initial implementation (not usable yet)
447 - added support for v2 multiple stage envelope generators
448 - added a fine-tuned v1 envelope generator instead of using the
449 one from the gig engine
450 - fixed memory leak and memory handling errors
451 - added support for trigger=first, trigger=legato and sw_previous
452 - allow non-numerical key values ("C#4" for example)
453 - "key" opcode now sets pitch_keycenter too
454 - fixed error when unloading instrument with same sample used by
455 multiple regions
456 - added some opcode aliases, like loopmode for loop_mode, to be
457 more compatible
458 - added support for trigger=release and rt_decay
459 - added support for off_mode=normal
460 - added support for random, seq_position, seq_length and volume
461 - added v1 LFO opcodes to parser (no support in engine yet)
462 - added support for amp_veltrack and amp_velcurve_N
463 - fine-tuned the default velocity curve
464 - added support for transpose
465 - fixed crash when using sw_down/up
466 - improved logic for sw_lokey/hikey/up/down/last
467 - added more v1 aliases to parser

894 is only used by very few systems, most pick the int math
895 implementation, which is usually faster)
896 - fixes for audio drivers with varying buffer sizes
897 - experimental support for running LinuxSampler as a DSSI, LV2 and
898 VST plugin
899 - notification events for stream/voice count statistics are now sent
900 only when there are actual changes
901 - added memory ordering constraints to improve stability on
902 multi-core and multi-cpu systems
903 - maximum voices and disk streams can now be altered at runtime
904 - fixed CPU feature detection on x86_64 (maybe fixes #108)
905 - automatic stacktrace mechanism is now turned off by default and can
906 be switched on by command line option "--stacktrace" (the automatic
907 stacktrace mechanism seems to be broken on most systems at the moment)
908 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
909 a pointer to the launched InstrumentEditor object
910 - added optional 3rd party user data parameter for following
911 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
912 InstrumentEditor::Launch(),
913 InstrumentManager::LaunchInstrumentEditor()
914 - theoretical fix: made SynchronizedConfig follow C++0x memory
915 model more strictly
916 - fixes for using large audio device buffers
917 - Windows: add the installation directory to the DLL search path
918 when loading an editor plugin (solves problems with VST and
919 gigedit on systems with other GTK versions installed)
920 - updated linuxsampler man page
922 * audio driver:
923 - removed the nonsense audio channel constraint (which was hard coded to
924 max. 100 audio channels) for most audio drivers
925 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
926 opposed to the LSCP specs
927 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
928 reflected the wrong value
929 - fixed a memory management bug in ASIO driver
930 - Makefile fix: JACK_CFLAGS wasn't used
931 - JACK: use jack_client_open instead of the deprecated
932 jack_client_new
933 - added (experimental) CoreAudio driver
934 - applied old fixes to the ASIO driver that were included in the
935 previous binary release but accidentally never committed to CVS
936 (fixes #117)
937 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
938 win64)
939 - VST: added support for sample rate and buffer size changes
940 - VST: close editor (Fantasia) when the VST is removed
941 - VST: avoid opening Fantasia more than once for each VST instance
942 - VST: export main function as "main" on Linux too (fix for
943 energyXT)
944 - VST: changed number of output channels from one stereo to 16
945 stereo
946 - added channel routing, fxsends and midi maps to the settings
947 stored in the plugin state
948 - performance optimization of AudioChannel::MixTo() and
949 AudioChannel::CopyTo() methods using GCC vector exensions
950 (if available)
951 - ASIO fixes: avoid initializing the device twice, avoid throwing
952 exception when getting parameters from a disconnected device
954 * MIDI driver:
955 - added JACK MIDI driver
956 - dispatch bank select as ordinary CC as well, the user might seriously
957 want to (mis)use it for some purpose ("fixed" in all current MIDI
958 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
959 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
960 CoreMidi or AU
961 - fixed mingw-w64 compilation error in MME driver
962 - made program change handling in MIDI thread real-time safe by
963 moving the logic to a non-RT thread
964 - fixed minor memory leak in ALSA driver
966 * instruments database:
967 - avoid time consuming samples scanning when adding instruments
968 to the instruments database
969 - added support for handling lost files in the instruments database
970 - Implemented option for adding instruments in separate directories
971 in the instruments database
972 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
973 - work-around for missing fnmatch function on Windows to make
974 instrument database compilable
975 - added instrument database support on Windows
976 works with both standalone mode and VST plugin.
977 the instruments DB file is located in
978 %USERPROFILE%\.linuxsampler\instruments.db which allows different
979 databases for each windows user
980 if no DB is present it automatically creates the .linuxsampler subdir
981 and then creates an empty DB
982 - fixed recursive import, which was broken on Windows
984 * Gigasampler format engine:
985 - fixed a memory leak that could happen when a channel was deleted
986 while notes were playing
987 - made it possible to load an instrument even if the audio thread
988 isn't running
989 - added partial support for the "Controller Triggered" MIDI rule,
990 enough for piano gigs with pedal noise samples
991 - minor fix: only mark FX sends as being modified if really the
992 respective FX send MIDI controller was used
993 - added support for GM global device volume SysEx message
994 (can be selected at compile time to either apply globally to the
995 whole sampler [default] or only to the sampler channels that are
996 connected to the respective MIDI input port the SysEx message arrived
997 on)
998 - bugfix: notes triggered at position 0 in the audio buffer were
999 sometimes wrongly killed in the same buffer, causing no sound to
1000 be played
1001 - added support for chromatic / drumkit mode Roland GS Sysex message
1002 which is usally used to switch a part between chromatic sounds and
1003 drumkit sounds (as opposed to their common default setting of MIDI
1004 part 10 being a drumkit part and all other ones chromatic parts), in
1005 LS however one can switch between the first 16 MIDI instrument maps
1006 defined for the sampler
1007 - made it possible to create multiple sample channels even if the
1008 audio thread isn't running
1009 - fixed crash when removing channel with active voices (#116)
1010 - bugfix: on sample reference changes (instrument editor), only
1011 un-cache the respective sample if it's really not used by any
1012 sampler engine anymore
1013 - re-cache samples in case they were changed by an instrument editor,
1014 e.g. when a sample was added while playing (#82)
1015 - fixed hanging notes which occured when note-off event had the exact
1016 same time stamp as the voice's note-on event and occured both in the
1017 same audio fragment cycle (fixes bug #112)
1018 - added support for the "fine tune" and "pitch bend range"
1019 instrument-level gig parameters
1020 - fixed minor artifacts in pitch bend handling
1021 - added support for GS Reset SysEx message
1022 - allow gig files to use unlimited downward pitch shifting
1023 - added a limit check for upward pitch shifting
1024 - bugfix: sometimes, when playing a note twice fast, the second
1025 note was silent
1026 - fixed crash happening when a pitch bend event arrived at the
1027 same time a new instrument was loading
1029 * LSCP server:
1030 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
1031 react on MIDI data arriving on certain sampler channels (so far only
1032 Note-On and Note-Off events are sent via this LSCP event)
1033 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1034 react on MIDI data arriving on certain MIDI input devices (so far only
1035 Note-On and Note-Off events are sent via this LSCP event)
1036 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
1038 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
1039 frontends to send MIDI messages to specific sampler channel
1040 - added two additional fields to GET FILE INSTRUMENT INFO command -
1042 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1043 was incorrect
1044 - Optimized the retrieval of the MIDI instrument mappings
1045 - added new LSCP command "SET VOICES" to globally alter the maximum
1046 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1047 be triggered respectively
1048 - added new LSCP command "SET STREAMS" to globally alter the maximum
1049 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1050 which will be triggered respectively
1051 - bugfix: retry if "select" returns EINTR (this fixes a crash when
1052 a gigedit file dialog is opened)
1053 - close all connections when LSCPServer is deleted
1054 - hard close of all sockets on exit
1055 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
1056 driver
1058 * Bug fixes:
1059 - fixed a crash which occurs when removing a sampler channel waiting
1060 to start instrument loading after another channel
1061 - fixed a crash which occurs when removing a sampler channel with
1062 instrument loading in progress (bug #113)
1063 - fixed termination caused by uncaught exception when adding MIDI
1064 instrument with PERSISTENT load mode
1065 - fixed possible iterator invalidations when resetting the sampler
1066 - fixed memory leaks when issuing the following LSCP commands:
1071 - fixed possible compilation error when sqlite is not present
1072 - fixed orphaned pointers when setting maximum voices limit (bug #118)
1073 - fixed crash when changing the audio output device of a sampler
1074 channel with loaded instrument and start playing notes
1075 - fixed endless loop in Engine::SuspendAll() (bug #120)
1076 - fixed a low-level atomic load function that was broken on 64-bit
1077 PowerPC, which probably could cause crashes on that platform
1078 - fixed a memory management error which could cause a crash when a
1079 plugin was unloaded
1080 - bugfix: two private structs had the same name, which could cause
1081 problems if the linker chose the wrong constructor
1082 - fixed low-level ConditionServer usage bug that caused lockups on
1083 Windows
1086 Version 0.5.1 (6 December 2007)
1088 * packaging changes:
1089 - added autoconf checks for pthread library
1090 - added autoconf check for pthread bug found on certain NPTL-enabled
1091 glibc versions (see Gentoo bug report #194076)
1092 - added autoconf checks for MS Windows
1094 * general changes:
1095 - bugfix: the thread used by an editor plugin didn't die when the
1096 editor closed
1097 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1098 out all the space. operator--() did not apply size_mask after
1099 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1100 order to avoid problems with the _NonVolatileReader functions.
1101 - bugfix: Stream.h: added a missing divide by BytesPerSample in
1102 GetWriteSpace(). Since this function is currently only used in
1103 the stream's qsort() compare function, it didn't trigger any
1104 bugs.
1105 - Resampler.h, Synthesizer.h: cubic interpolation now works in
1106 24bit mode too. Faster method to read 24bit words on little
1107 endian machines (x86): replaced 3 byte reads + shifts with a 1
1108 unaligned 32bit read and shift
1109 - experimental support for MS Windows (MIDI input via MME, AUDIO
1110 output via ASIO)
1111 - made handling of SIGINT signal (Ctrl-C) a bit more robust
1112 - support for monitoring the total number of active disk streams
1113 (new LSCP commands: GET TOTAL_STREAM_COUNT,
1116 * AUDIO driver:
1117 - added Windows ASIO low latency audio driver
1119 * MIDI driver:
1120 - added MME Windows MIDI driver
1122 * LSCP server:
1123 - added support for Windows style path / filenames, however with
1124 forward slash path separators instead of backslash
1125 (i.e. "C:/foo/bar.gig")
1126 - allow naughty liblscp to send non-string device parameters within
1127 apostrophes as well
1128 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1129 "LIST FILE INSTRUMENTS <file>" and
1130 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1131 about an arbitrary instrument file on the system where the sampler is
1132 running on
1134 Version 0.5.0 (15 October 2007)
1136 * packaging changes:
1137 - config.h is not going to be installed along with liblinuxsampler's
1138 API header files anymore
1139 - only the API relevant header (and source) files will be exported to
1140 the Doxygen API documentation (explicitly listed in Doxyfile.in)
1141 - added completely new XCode project files for Mac OSX which is now
1142 capable to execute our autoconf environment, thus no need anymore
1143 to maintain the compile time configuration file (osx/version.h) for
1144 OSX manually (patch by Toshi Nagata)
1145 - fixed buggy boolean --enable-foo / --disable-foo configure script
1146 parameters
1147 - global.h now only covers global definitions that are needed for the
1148 C++ API header files, all implementation internal global definitions
1149 are now in global_private.h
1150 - atomic.h is not exposed to the C++ API anymore
1151 - no need to include config.h anymore for using LS's API header files
1152 - fixed warnings in API doc generation
1154 * general changes:
1155 - replaced the old, confusing MIDI program change mechanism by a
1156 flexible MIDI instrument mapper which allows to map arbitrary
1157 (MIDI bank, MIDI program) pairs with arbitrary
1158 (engine type, instrument file, file index) triplets which will be
1159 loaded on the respective channel when such MIDI program change
1160 messages arrive, beside that, each entry allows to define a life-time
1161 strategy for the instrument, so the user can define whether the
1162 instrument should i.e. be permanently loaded (to be able to switch
1163 quickly among sounds) or i.e. loaded just on demand when the
1164 respective program change arrives (to safe RAM space), as well as a
1165 global volume factor for each entry, so the user can adjust the volume
1166 dynamic of his mapped instrument collection without having to modify
1167 the instrument files, also one can manage arbitrary amount of such
1168 MIDI instrument maps and assign each sampler channel individually
1169 a certain map, so that i.e. separation of normal instruments and
1170 drumkits is possible
1171 - new notification events for tracking changes to audio/MIDI devices,
1172 MIDI instrument maps, MIDI instruments, FX sends, global volume.
1173 - sampler was limited to load max. 200 instruments in the background
1174 due to a constant size RingBuffer FIFO which is now replaced by a
1175 dynamic (unlimited) size std::list FIFO
1176 - added FX sends, these allow to route audio signals to arbitrary audio
1177 output channels for being processed by external effect processors
1178 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1179 controllers
1180 - global (sampler wide) volume can now be controlled at runtime
1181 - Implemented new, improved notification system
1182 - fixed compilation errors regarding OSX
1183 (patch by Toshi Nagata)
1184 - implemented instruments database
1185 - added support for escape sequences to the instruments database
1186 - added highly experimental support for on-the-fly instrument editing
1187 within the sampler's process (by using instrument editor plugins),
1188 you'll notice the new "Registered instrument editors:" message on
1189 startup, added a new LSCP command:
1190 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1191 to spawn a matching instrument editor for the instrument on the
1192 given sampler channel, the plugin path can be overridden at compile
1193 time with ./configure --enable-plugin-dir=/some/dir
1194 - added experimental code for synchronizing instrument editors hosted
1195 in the sampler's process to safely edit instruments while playing
1196 without a crash (hopefully) by either suspending single regions
1197 wherever possible or if unavoidable whole engine(s)
1198 - fixed several issues in fundamental "Thread" class: set scheduling
1199 policy and priority on thread level, set a minimum stack size for
1200 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1201 threads simply inherited properties of starting thread instead of
1202 setting their own policy and priority
1203 - minor fix in our automatic stack trace mechanism on crashes, the
1204 main process did not wait for the stack trace process to finish
1205 its output
1206 - fixed some minor memory leaks
1207 - reenabled assembly features support, at the moment only for
1208 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1209 - minor assembly fix in x86 features detection (don't use the PIC
1210 register, to avoid relocations in the text segment at runtime)
1211 - POSIX callback functions of Thread.h are hidden
1213 * MIDI driver:
1214 - dispatch bank select (MSB and LSB) messages
1216 * audio driver:
1217 - the ALSA audio output driver parameters now reflect the correct
1218 parameter value ranges for the respective selected sound card
1219 (patch by Till Wimmer, a bit fixed and extended)
1221 * Gigasampler format engine:
1222 - if a filter is used and EG2 finishes before EG1, let the voice
1223 die when EG2 has finished (this fixes a problem with clicks and
1224 voice starvation for some gigs)
1225 - playback is no longer disabled during instrument loading
1226 - all notes playing on a channel that changes its instrument keep
1227 playing with the old instrument until they get a note off
1228 command
1229 - EG fix: a release value of zero could cause noises or crash
1230 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1231 - EG fine tuning: when attack is zero the EG starts at a level
1232 above max sustain level, which means that there is a decay phase
1233 even if sustain is 100%
1234 - more EG fixes: the level could sometimes go below zero and cause
1235 noises or crashes
1236 - minor fix of EGDecay (patch by Toshi Nagata)
1237 - fixed compiler error when --enable-override-filter-type was
1238 supplied to the configure script (fixes #46)
1239 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1240 instead of a fix value
1241 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1242 127 (solo mode) only kill voices if the respective mode really
1243 changed
1245 * LSCP server:
1246 - fixed compile time error for old Bison versions
1247 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1248 - parser now supports extended ASCII character set
1249 (up to ASCII code 255, i.e. includes now umlauts and accents)
1250 - filename arguments in LSCP commands now allow to use escape
1251 sequences, that is directly literal as one of: \', \", \\, \n, \r,
1252 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1253 code value like \xf2) (fixes bug #24)
1254 - the following LSCP commands now also support escape sequences for at
1255 least one of their text-based parameters (i.e. name, description):
1262 - returns verbose syntax errors (line and column where syntax error
1263 occured, the unexpected character and the actually expected, possible
1264 character(s), the latter only if less than 5 possibilities)
1265 - made sure that LSCP syntax is not affected by gigedit locale
1266 settings
1267 - bugfix regarding strings parameter lists: all comma separated lists
1268 of strings were treated as being one string containing commas
1269 (fixes #57)
1271 * Bug fixes:
1272 - fixed crash occurring on certain LSCP scripts (Bug 39)
1273 - another thread safety fix for lscp "load engine" and "set
1274 channel audio output device"
1275 - fixed a crash which occurs when reassigning the same engine
1276 on a sampler channel with connected MIDI device
1277 - fixed a crash which occurs when changing the number of ports of a MIDI
1278 device connected to a sampler channel to number less then or equal
1279 to the index of the port to which the sampler channel is connected.
1280 - The previous bindings were not been disconnected when altering
1281 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1282 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1283 - The active stream/voice count statistic was incorrect.
1284 - notification events were not been sent for some sampler
1285 channel changes
1286 - added default min and max values to restrict the number of allowed
1287 audio output channels and MIDI input ports
1288 - the connection to the PCM interface is now closed when destroying
1289 an audio output device
1290 - files with slash in their path or filename could not be loaded
1292 * test cases:
1293 - updated and fixed (haven't been touched in a while)
1295 Version 0.4.0 (24 November 2006)
1297 * packaging changes:
1298 - changed deprecated copyright attribute to license; added ldconfig
1299 to post-(un)install steps; added devel package for liblinuxsampler;
1300 to linuxsampler.spec (RPM)
1301 - install necessary development header files for allowing 3rd party
1302 applications to link against liblinuxsampler
1303 - liblinuxsampler's API documentation can be generated with 'make docs'
1304 (Doxygen required)
1305 - added benchmark to automatically detect the best triangle LFO
1306 implementation (currently either an integer math solution or a
1307 di-harmonic approximation), automatic detection can be overriden
1308 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1309 configure script argument though (mandatory for cross-compilation)
1310 - do not automatically pick optimized gcc flags if the user already
1311 provided some on his own (as CXXFLAGS)
1312 - added compile time option to disable processing of All-Notes-Off MIDI
1313 messages
1314 - added compile time options to allow disabling the various audio and
1315 MIDI drivers
1316 - fixed automatic GCC CPU switch detection on PPC
1317 (patch by Ebrahim Mayat)
1319 * Gigasampler format engine:
1320 - extensive synthesis optimization
1321 (reimplementation of EGs and LFO(s), removed synthesis parameter
1322 prerendering and the synthesis parameter matrix in general, splitting
1323 each audio fragment into subfragments now where each subfragment uses
1324 constant pitch and filter coefficients. The volume coefficient is
1325 linearly interpolated inside a subfragment, unless
1326 --disable-interpolate-volume is set.)
1327 - fine tuning of the EG modulation parameters
1328 - improved filter cutoff calculation by adding support for the
1329 following gig parameters: Cutoff freq (used when no cutoff
1330 controller is defined), Control invert, Minimum cutoff, Velocity
1331 curve and Velocity range. The keyboard tracking now scales
1332 cutoff frequency instead of resonance.
1333 - added support for gig parameter Resonance.
1334 - fixed bug in sysex handling (patch by Juan Linietsky)
1335 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1336 which can be overridden with --enable-global-attenuation
1337 - EG fixes: made the length of "attack hold" stage more
1338 accurate. Release stage can now start before attack stage
1339 ends. Cancel release didn't work when sustain was zero. Attack
1340 time now has a minimal value to prevent clicks.
1341 - fixed pitch changes larger than one octave
1342 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1343 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1344 all modes can be altered via standard GM messages, that is CC5 for
1345 altering portamento time, CC65 for enabling / disabling portamento
1346 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1347 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1348 parameter) and crossfade
1349 - added support for the "attenuation controller threshold" gig
1350 parameter
1351 - added smoothing of volume changes caused by control change
1352 messages
1353 - sample loop parameters are now taken from the DimensionRegion
1354 instead of the wave chunk
1355 - fixed keyswitching for v3 gigs with a number of keyswitch splits
1356 not equal to a power of two
1357 - reimplementation of the filter algorithm. The new filter is more
1358 accurate and supports all gig filter types, including bandreject
1359 and lowpass turbo.
1360 - real support for 24 bit samples - samples are not truncated to
1361 16 bits anymore
1362 - support for aftertouch (channel pressure, not polyphonic
1363 aftertouch)
1364 - LFO1 behaviour fixed (dampening from max volume instead of
1365 amplifying from 0)
1367 * LSCP server:
1368 - fixed application exit on broken pipe error (fixes bug #20)
1369 - fixed the notification messages delay due to lack of
1370 network activity (fixes bug #26)
1371 - fixed parser bug which occured on space(s) within device parameters
1374 * audio driver:
1375 - added aRts audio output driver (by no means RT safe)
1377 * MIDI driver:
1378 - fixed legacy sysex code which caused dispatching of MIDI SysEx
1379 messages several times instead of once
1380 - API extension for MIDI drivers which already supply exact time stamps
1381 for events (i.e. for offline rendering based MIDI drivers)
1382 - added checks for bad MIDI data
1384 * linuxsampler application:
1385 - show available sampler engine types on startup
1387 * general changes:
1388 - support for muting sampler channels and solo mode of the same, two new
1389 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1390 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1391 introduced for this, the behavior is the same like on a mixer console
1392 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1393 --enable-process-muted-channels which can be used to enable the
1394 processing of muted channels.
1395 - support for sostenuto pedal
1396 - support for monitoring the total number of active voices
1399 - fixed some memory management errors
1400 - fixed some concurrency problems that could lead to crashes when
1401 LSCP commands were executed
1402 - fixed crash when instrument loading failed previously on the same
1403 sampler channel (fixes bug #36)
1405 Version 0.3.3 (15 July 2005)
1407 * packaging changes:
1408 - fixed compilation with gcc 4.0
1410 * Gigasampler format engine:
1411 - LFO preprocessing was performed even though the respective LFO was
1412 disabled by the instrument patch (minor efficiency fix)
1413 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1414 for volume ramp downs in the same fragment (needed for current voice
1415 stealing implementation) then simply inform the user with a warning
1416 about possible click sounds and reduce the volume ramp down
1417 appropriately instead of cancelling the audio device connection
1419 Version 0.3.2 (24 June 2005)
1421 * packaging changes:
1422 - updated autotools build files to compile on OS X
1423 (conditional compilation of CoreMIDI and MidiShare drivers)
1424 - hand-crafted assembly optimization code can be disabled with
1425 './configure --disable-asm' (definitely not recommended)
1426 - fixed 'make dist' rule to include all necessary files
1427 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1428 (due to 'dist-bzip2' automake option)
1430 * Gigasampler format engine:
1431 - support for the gig parameters for "release velocity response" curves
1432 - fine tuning of the EGADSR envelope
1433 - volume of release triggered samples now depends on note-on velocity,
1434 note length and gig parameter "release trigger decay" instead of
1435 note-off velocity.
1436 - revised voice stealing
1437 (fixes crash and endless loop caused by voice stealing)
1438 - don't reset scale tuning on instrument or audio output device change
1439 - handle key group conflicts right at the beginning of each fragment
1440 instead of when the respective voice is actually launched
1441 (fixes undefined behavior if stolen voices belonged to a key group -
1442 this case was followed by a "killed voice survived" error message)
1443 - fixed minor issue with null/silence samples
1444 (those stole voices even though they don't need a voice at all which
1445 resulted in "voice stealing didn't work out" messages)
1446 - don't reset volume, pan, pitch and MIDI controller values on
1447 instrument or audio output device change
1449 * LSCP server:
1450 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1451 - fixed LSCP event "CHANNEL_INFO" notification
1452 (e.g. did not notify on volume changes or MIDI program change events)
1454 * linuxsampler application:
1455 - added command line parameters --lscp-addr and --lscp-port to override
1456 default IP address and port of LSCP server
1458 Version 0.3.1 (24 May 2005)
1460 * initial release
