* NKSP: Added built-in script function "change_cutoff_attack()".
* NKSP: Added built-in script function "change_cutoff_decay()".
* NKSP: Added built-in script function "change_cutoff_sustain()".
* NKSP: Added built-in script function "change_cutoff_release()".
* NKSP: Added built-in script function "change_cutoff_lfo_depth()".
* NKSP: Added built-in script function "change_cutoff_lfo_freq()".
* Bumped version (2.0.0.svn77).

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

136 handled by the script parser).
137 - Added built-in script constant "$NI_CB_TYPE_INIT".
138 - Added built-in script constant "$NI_CB_TYPE_NOTE".
139 - Added built-in script constant "$NI_CB_TYPE_RELEASE".

142 - Implemented built-in script function "change_attack()".
143 - Implemented built-in script function "change_decay()".
144 - Implemented built-in script function "change_release()".
145 - Fixed all change_*() built-in script functions to apply their
146 synthesis parameter changes immediately in case the respective note
147 was triggered at the same time, instead of scheduling the parameter
148 change, especially because it would cause some parameter types's
149 changes either to be ramped (i.e. change_vol()) or other types even
150 to have not effect at all (i.e. change_attack()).
151 - Implemented built-in script function "sh_left()".
152 - Implemented built-in script function "sh_right()".
153 - Implemented built-in script function "min()".
154 - Implemented built-in script function "max()".
155 - NKSP Fix: "init" event handler was not always executed when a script
156 was loaded.
157 - NKSP built-in wait() script function: abort script execution if
158 a negative or zero wait time was passed as argument (since this is
159 a common indication of a bug either of the script or even of the
160 engine, which could lead to RT instability or even worse).
161 - ScriptVM: Implemented automatic suspension of RT safety
162 threatening scripts.
163 - Provide more user friendly error messages on syntax errors.
164 - Fixed NKSP parser warning "Not a statement" when assigning an
165 initializer list to an array variable.

168 - Implemented built-in script function "change_amp_lfo_depth()".
169 - Implemented built-in script function "change_amp_lfo_freq()".
170 - Implemented built-in script function "change_pitch_lfo_depth()".
171 - Implemented built-in script function "change_pitch_lfo_freq()".
172 - Implemented built-in script function "change_vol_time()".
173 - Implemented built-in script function "change_tune_time()".
174 - Implemented built-in script function "fade_in()".
175 - Implemented built-in script function "fade_out()".
176 - Fixed acceptance of wrong data type of parameters passed to built-in
177 script functions "change_vol()", "change_tune()", "change_pan()",
178 "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
179 "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
180 "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
181 - Added built-in script function "get_event_par()" and implemented some
182 of its possible parameter selections.
183 - Added built-in script function "set_event_par()" and implemented some
184 of its possible parameter selections.
185 - Fixed a bunch of scheduler time related bugs.
186 - Fixed polyphonic variables not being reset to zero after usage.
187 - Built-in "ignore_event()" function: argument is now optional, like with
188 built-in function "ignore_controller()".
189 - Implemented built-in script function "change_velo()".
190 - Implemented built-in script function "change_note()".
191 - Adjusted behavior of "change_vol()" and "change_tune()" to a more
192 intuitive behavior if used in combination with "change_vol_time()" or
193 "change_tune_time()" respectively: now tuning/volume changes are only
194 assigned (without delay) immediately to a new note if the respective
195 timing function has not been called before, otherwise the volume/tuning
196 changes are automatically faded (before, only the event's time stamp was
197 relevant).
198 - Implemented built-in script function "array_equal()".
199 - Implemented built-in script function "search()".
200 - Implemented built-in script function "sort()".
201 - NKSP Fix: Never suspend "init" event handlers.
202 - Implemented built-in script function "same_region()" (currently only
203 available for gig format engine).
204 - Added built-in script constant "$NKSP_LINEAR".
205 - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
206 - Implemented built-in script function "change_vol_curve()".
207 - Implemented built-in script function "change_tune_curve()".
208 - built-in "play_note()" function now supports a sample playback start
209 offset with argument 3, where special value -1 means to use the regular
210 sample offset as defined by the instrument file.
211 - Built-in array variable %KEY_DOWN[] is now a read-only variable.
212 - Built-in variable $EVENT_NOTE is now a read-only variable.
213 - Built-in variable $EVENT_VELOCITY is now a read-only variable.
214 - built-in "play_note()" function now accepts -2 for its fourth argument
215 (note duration) which means the life time of the note shall be sticked
216 to the requested note number of argument 1.
217 - Fix: built-in "play_note()" function now returns 0 as result value if
218 -1 was passed for its fourth argument (note duration) and the respective
219 parent note is already gone.
220 - Implemented built-in script function "change_play_pos()".
221 - NKSP language: Added support for user declared const array variables.
222 - NKSP language: Raise parser warning if array variable is accessed with
223 an index that exceeds the array's size.
224 - NKSP language fix: Unknown characters were not handled correctly.
225 - NKSP language: Added support for "synchronized .. end synchronized"
226 code blocks.
227 - Implemented built-in script function "abort()" which allows to abort
228 another script handler by passing its callback ID.
229 - Fixed potential memory access bug and potential undefined behavior of
230 "init" event handlers.
231 - Print a time stamp along to each call of built-in function "message()".
232 - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
233 to retrieve all code blocks filtered out by the preprocessor.
234 - Added built-in script function "fork()".
235 - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
236 - Added built-in variable $NKSP_CALLBACK_PARENT_ID.
237 - Fixed potential crash when accessing dynamic built-in array variables.
238 - Added built-in script function "callback_status()".
239 - Added built-in constant $CALLBACK_STATUS_TERMINATED.
240 - Added built-in constant $CALLBACK_STATUS_QUEUE.
241 - Added built-in constant $CALLBACK_STATUS_RUNNING.
242 - Removed max. value limitation of built-in functions "change_attack()",
243 "change_decay()" and "change_release()" to i.e. allow passing 2000000
244 for doubling the respective time.
245 - NKSP script editor syntax highlighting API: Fixed app termination due
246 to a lexer start condition stack underrun.
247 - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
248 USE_CODE_IF_NOT() preprocessor statements.
249 - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
250 can be set to disable all subsequent built-in "message()" function calls
251 on preprocessor level.
252 - Implemented built-in script function "change_sustain()".
253 - NKSP script editor syntax highlighting API: catch all fatal lexer errors,
254 to avoid the editor app to crash on ill-formed text input.

265 - Fixed memory access bug of general DB access code which lead to
266 undefined behavior.
267 - Cleanup of instruments DB file creation and opening code.
268 - The instrument DB path of linuxsampler's --create-instruments-db argument
269 is now optional, if it is missing, then a default location is used.
270 - Added support for scanning SFZ (.sfz) files.
271 - Added support for scanning Sound Font (.sf2) files.
272 - Fixed undefined DB transaction behavior.

277 - fixed building with newer MinGW-w64
278 - Mac OS X: support the new dir for Core Audio SDK
279 - Mac OS X: fixed building outside source directory
280 - made sure all source files for hostplugins are included when
281 doing "make dist"
282 - removed empty directories left from the cvs to svn migration
283 - fixed compilation with gcc 4.6.1
284 - another "make dist" fix, for the LV2 plugin
285 - made --enable-pthread-testcancel default on Mac OS X
286 - minor Makefile fix for building lscpparser when build and source
287 directories are separate
288 - Mac OS X: made it possible to specify plugin installation dir to
289 configure
290 - Mac OS X: Makefile fix for the install-strip target
291 - fixed compilation with gcc 4.7
292 - fixed configure script error with old autoconf versions
293 - lsatomic.h: use gcc provided atomic functions if building with
294 gcc 4.7 and C++11
295 - modernized configure script
296 - fixed linkage error when building with
297 LDFLAGS="-Wl,--no-undefined" (#190)
298 - fixed compilation with Clang 3.2
299 - removed usage of deprecated Automake variable INCLUDES

302 - build fix: libsndfile compiler flags were missing in some
303 makefiles
304 - fix for building with bison 3.0 (#202)
305 - Mac OS X: added temporary hack allowing to spawn gigedit as callback
306 on the process's main thread
307 - fixed build error on newer MinGW
308 - support building with older jack versions
309 - support building with spaces in vst sdk path
310 - enabled automake 'subdir-objects' option and moved external
311 source references (vst, au, asio) from makefiles to cpp files,
312 in order to get rid of warnings from automake 1.14
314 * general changes:
315 - Refactoring: moved the independent code from
316 the Gigasampler format engine to base classes
317 - command line option '--profile' is currently disabled, since the
318 respective profiling code is currently broken
319 - Introduced support for optional environment variable
320 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
321 where the sampler shall look for instrument editor plugins
322 (patch by Luis Garrido, slightly modified).
323 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
324 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
325 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
326 note (in this implementation of the sampler its simply hard routed to
327 the 1st effect send of the sampler channel, no matter what the actual
328 effect type is)
329 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
330 note (in this implementation of the sampler its simply hard routed to
331 the 2nd effect send of the sampler channel, no matter what the actual
332 effect type is)
333 - implemented support for internal LADSPA effects
334 - raised limit of program change queue from 100 to 512
335 (as suggested by Alex Stone)
336 - implemented sine LFO, pulse LFO and saw LFO
337 - experimental support for per voice equalization
338 - added command line option --exec-after-init
339 - Introduced new C++ API method:
340 EngineChannel::InstrumentFileName(int index)
341 allowing to retrieve the whole list of files used for the loaded
342 instrument on an engine channel (a.k.a. part). Some GigaStudio
343 instruments for example are splitted over several files like
344 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
345 - Added new C++ API method Sampler::GetGlobalMaxVoices().
346 - Added new C++ API method Sampler::GetGlobalMaxStreams().
347 - Added new C++ API method Sampler::SetGlobalMaxVoices().
348 - Added new C++ API method Sampler::SetGlobalMaxStreams().
349 - Various "const" and "restrict" optimizations.
350 - all engines: add pan CC value to instrument pan parameter before
351 applying panning, instead of using two separate pan functions in
352 series (#182)
353 - added a lock guard class for exception safe mutex handling and
354 used it everywhere appropriate
355 - Immediately apply scale tuning changes to active voices.
356 - Exposed scale tuning to C++ API (along to the already existing standard
357 SysEx way).
358 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
359 and broken for ppc64. (Seq_cst loads and stores are actually not
360 used in LS, so the bug wasn't noticable.)
361 - lsatomic.h: added ARMv7 support
362 - Added support for multiple MIDI input ports per sampler channel (and
363 added various new C++ methods for this new feature / design change, old
364 C++ API methods for managing SamplerChannel's MIDI inputs are now marked
365 as deprecated but are still there and should provide full behavior
366 backward compatibility).
367 - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
368 unsafe and caused compilation error with clang 2.x).
369 - Bugfix: only process the latest MIDI program change event.
370 - Introducing the LSCP shell, which provides convenient control of the
371 sampler from the command line by providing LSCP aware features.
372 - VirtualMidiDevice: Added support for program change.
373 - VirtualMidiDevice: Added support for bank select (MSB & LSB).
374 - VirtualMidiDevice: Added support for pitch bend.
375 - Aftertouch: extended API to explicitly handle channel pressure and
376 polyphonic key pressure events (so far polyphonic pressure was not
377 supported at all, and channel pressure was rerouted as CC128 but not
378 used so far).
379 - Added initial support for real-time instrument scripts. The script VM
380 code is shared by all sampler engine implemementations, however only the
381 gig file format currently provides support for storing instrument scripts
382 (as LinuxSampler extension to the original GigaStudio 4 format).
384 * Gigasampler format engine:
385 - implemented the "round robin keyboard" dimension
386 - fixed round robin and random dimensions for cases when number of
387 dimension zones is not a power of two
388 - made round robin use a counter for each region instead of each
389 key
390 - bugfix: pitch LFO controller "internal+aftertouch" was broken
391 - bugfix: filter keyboard tracking was broken
392 - filter performance fix (an unnecessary copy was made of the
393 filter parameters in each sub fragment)
394 - handle special case when pan parameter in gig file has max or
395 min value
396 - Exclusive Groups: don't ever stop voices of the same note,
397 doesn't sound naturally with a drumkit
398 - fixed EG1 modulation when attack or release is zero
399 - Fixed support for 'aftertouch' attenuation controller.
400 - Fixed crash that happened with velocity split sounds under certain
401 conditions (see also previous commit on libgig).
402 - fixed behaviour of filter LFO
404 * SFZ format engine:
405 - Initial implementation (not usable yet)
406 - added support for v2 multiple stage envelope generators
407 - added a fine-tuned v1 envelope generator instead of using the
408 one from the gig engine
409 - fixed memory leak and memory handling errors
410 - added support for trigger=first, trigger=legato and sw_previous
411 - allow non-numerical key values ("C#4" for example)
412 - "key" opcode now sets pitch_keycenter too
413 - fixed error when unloading instrument with same sample used by
414 multiple regions
415 - added some opcode aliases, like loopmode for loop_mode, to be
416 more compatible
417 - added support for trigger=release and rt_decay
418 - added support for off_mode=normal
419 - added support for random, seq_position, seq_length and volume
420 - added v1 LFO opcodes to parser (no support in engine yet)
421 - added support for amp_veltrack and amp_velcurve_N
422 - fine-tuned the default velocity curve
423 - added support for transpose
424 - fixed crash when using sw_down/up
425 - improved logic for sw_lokey/hikey/up/down/last
426 - added more v1 aliases to parser
427 - reduced memory usage for sfz data
428 - RT-safeness: avoid malloc in audio thread
429 - fixed a bug that could cause voice stealing to fail
430 - optimized sample lookup
431 - improved support for exclusive groups (group, off_by and
432 off_mode)
433 - added support for controller triggered regions (on_locc/on_hicc)
434 - added support for loop_mode=one_shot
435 - fixed playback of 16 bit wav files on big endian CPUs
436 - added support for Ogg Vorbis sample files
437 - use loop markers from sample file if loop_start and loop_end are
438 not set in sfz file
439 - implemeted filters. Filter types: lowpass, bandpass, bandreject
440 and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,
441 cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
442 cutoff_cc, cutoff_chanaft.
443 - bugfix: zero ampeg_sustain didn't work
444 - added support for velocity effect on amplifier envelope time
445 (ampeg_vel2attack, ampeg_vel2decay, ampeg_vel2sustain and
446 ampeg_vel2release)
447 - added support for EG hold (ampeg_hold)
448 - added support for sample offset (offset)
449 - use the newly introduced signal units model
450 - implemented opcodes lfoN_delay,
451 lfoN_freq, lfoN_pan, lfoN_cutoff, lfoN_resonance
452 - implemented opcodes ampeg_delay, ampeg_vel2delay

634 - added support for MIDI note on velocity filter
635 - CoreMIDI: fixed memory deallocation error
636 - Fixed variable underflow in VirtualMidiDevice, which caused graphical
637 virtual keyboards in frontends / instrument editors being stuck.

806 crashes and noise on such transitions).
807 - ignore missing LADSPA paths without ignoring valid LADSPA paths
808 (fixes #208)
809 - Fixed bug in LSCP grammar definition which caused a statement like
810 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
811 practically irrelevant, however it caused problems with the new LSCP
812 shell's auto completion feature).
813 - Fixed MIDI program change messages being ignored if quickly executed
814 after each other (fixes #231).
816 Version 1.0.0 (31 July 2009)
818 * packaging changes:

838 * general changes:
839 - bugfix: on some POSIX systems instrument editor plugins refused to
840 load as we used a non-portable Linux specific struct field
841 (fixes bug #70, patch by Ronald Baljeu)
842 - fixed endless loop which occured when loading an instrument editor
843 plugin DLL on Windows systems failed
844 - fixed memory leaks that occurred when liblinuxsampler was unloaded
845 - optimized the SynchronizedConfig class so it doesn't wait
846 unnecessarily long after an update

848 events (e.g. to highlight the pressed keys on the virtual keyboard
849 of gigedit)
850 - added support for triggering notes by instrument editors (see above)
851 - be verbose on DLL load errors (on Linux)
852 - fixed di-harmonic triangle LFO implementation (this LFO implementation
853 is only used by very few systems, most pick the int math
854 implementation, which is usually faster)
855 - fixes for audio drivers with varying buffer sizes
856 - experimental support for running LinuxSampler as a DSSI, LV2 and
857 VST plugin
858 - notification events for stream/voice count statistics are now sent

861 multi-core and multi-cpu systems
862 - maximum voices and disk streams can now be altered at runtime
863 - fixed CPU feature detection on x86_64 (maybe fixes #108)
864 - automatic stacktrace mechanism is now turned off by default and can
865 be switched on by command line option "--stacktrace" (the automatic
866 stacktrace mechanism seems to be broken on most systems at the moment)
867 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
868 a pointer to the launched InstrumentEditor object
869 - added optional 3rd party user data parameter for following
870 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
871 InstrumentEditor::Launch(),
872 InstrumentManager::LaunchInstrumentEditor()
873 - theoretical fix: made SynchronizedConfig follow C++0x memory
874 model more strictly
875 - fixes for using large audio device buffers
876 - Windows: add the installation directory to the DLL search path
877 when loading an editor plugin (solves problems with VST and
878 gigedit on systems with other GTK versions installed)
879 - updated linuxsampler man page
881 * audio driver:
882 - removed the nonsense audio channel constraint (which was hard coded to
883 max. 100 audio channels) for most audio drivers
884 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
885 opposed to the LSCP specs
886 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
887 reflected the wrong value
888 - fixed a memory management bug in ASIO driver
889 - Makefile fix: JACK_CFLAGS wasn't used
890 - JACK: use jack_client_open instead of the deprecated
891 jack_client_new
892 - added (experimental) CoreAudio driver
893 - applied old fixes to the ASIO driver that were included in the
894 previous binary release but accidentally never committed to CVS
895 (fixes #117)
896 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
897 win64)
898 - VST: added support for sample rate and buffer size changes
899 - VST: close editor (Fantasia) when the VST is removed
900 - VST: avoid opening Fantasia more than once for each VST instance
901 - VST: export main function as "main" on Linux too (fix for
902 energyXT)
903 - VST: changed number of output channels from one stereo to 16
904 stereo
905 - added channel routing, fxsends and midi maps to the settings
906 stored in the plugin state
907 - performance optimization of AudioChannel::MixTo() and
908 AudioChannel::CopyTo() methods using GCC vector exensions
909 (if available)
910 - ASIO fixes: avoid initializing the device twice, avoid throwing
911 exception when getting parameters from a disconnected device
913 * MIDI driver:
914 - added JACK MIDI driver
915 - dispatch bank select as ordinary CC as well, the user might seriously
916 want to (mis)use it for some purpose ("fixed" in all current MIDI
917 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
918 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
919 CoreMidi or AU
920 - fixed mingw-w64 compilation error in MME driver
921 - made program change handling in MIDI thread real-time safe by
922 moving the logic to a non-RT thread
923 - fixed minor memory leak in ALSA driver
925 * instruments database:
926 - avoid time consuming samples scanning when adding instruments
927 to the instruments database
928 - added support for handling lost files in the instruments database
929 - Implemented option for adding instruments in separate directories
930 in the instruments database
931 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
932 - work-around for missing fnmatch function on Windows to make
933 instrument database compilable
934 - added instrument database support on Windows
935 works with both standalone mode and VST plugin.
936 the instruments DB file is located in
937 %USERPROFILE%\.linuxsampler\instruments.db which allows different
938 databases for each windows user
939 if no DB is present it automatically creates the .linuxsampler subdir
940 and then creates an empty DB
941 - fixed recursive import, which was broken on Windows
943 * Gigasampler format engine:
944 - fixed a memory leak that could happen when a channel was deleted
945 while notes were playing
946 - made it possible to load an instrument even if the audio thread
947 isn't running
948 - added partial support for the "Controller Triggered" MIDI rule,
949 enough for piano gigs with pedal noise samples
950 - minor fix: only mark FX sends as being modified if really the
951 respective FX send MIDI controller was used
952 - added support for GM global device volume SysEx message
953 (can be selected at compile time to either apply globally to the
954 whole sampler [default] or only to the sampler channels that are
955 connected to the respective MIDI input port the SysEx message arrived
956 on)
957 - bugfix: notes triggered at position 0 in the audio buffer were
958 sometimes wrongly killed in the same buffer, causing no sound to
959 be played
960 - added support for chromatic / drumkit mode Roland GS Sysex message
961 which is usally used to switch a part between chromatic sounds and
962 drumkit sounds (as opposed to their common default setting of MIDI
963 part 10 being a drumkit part and all other ones chromatic parts), in
964 LS however one can switch between the first 16 MIDI instrument maps
965 defined for the sampler
966 - made it possible to create multiple sample channels even if the
967 audio thread isn't running
968 - fixed crash when removing channel with active voices (#116)
969 - bugfix: on sample reference changes (instrument editor), only
970 un-cache the respective sample if it's really not used by any
971 sampler engine anymore
972 - re-cache samples in case they were changed by an instrument editor,
973 e.g. when a sample was added while playing (#82)
974 - fixed hanging notes which occured when note-off event had the exact
975 same time stamp as the voice's note-on event and occured both in the
976 same audio fragment cycle (fixes bug #112)
977 - added support for the "fine tune" and "pitch bend range"
978 instrument-level gig parameters
979 - fixed minor artifacts in pitch bend handling
980 - added support for GS Reset SysEx message
981 - allow gig files to use unlimited downward pitch shifting
982 - added a limit check for upward pitch shifting
983 - bugfix: sometimes, when playing a note twice fast, the second
984 note was silent
985 - fixed crash happening when a pitch bend event arrived at the
986 same time a new instrument was loading
988 * LSCP server:
989 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
990 react on MIDI data arriving on certain sampler channels (so far only
991 Note-On and Note-Off events are sent via this LSCP event)
992 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
993 react on MIDI data arriving on certain MIDI input devices (so far only
994 Note-On and Note-Off events are sent via this LSCP event)
995 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
997 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
998 frontends to send MIDI messages to specific sampler channel
999 - added two additional fields to GET FILE INSTRUMENT INFO command -
1001 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1002 was incorrect
1003 - Optimized the retrieval of the MIDI instrument mappings
1004 - added new LSCP command "SET VOICES" to globally alter the maximum
1005 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1006 be triggered respectively
1007 - added new LSCP command "SET STREAMS" to globally alter the maximum
1008 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1009 which will be triggered respectively
1010 - bugfix: retry if "select" returns EINTR (this fixes a crash when
1011 a gigedit file dialog is opened)
1012 - close all connections when LSCPServer is deleted
1013 - hard close of all sockets on exit
1014 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
1015 driver
1017 * Bug fixes:
1018 - fixed a crash which occurs when removing a sampler channel waiting
1019 to start instrument loading after another channel
1020 - fixed a crash which occurs when removing a sampler channel with
1021 instrument loading in progress (bug #113)
1022 - fixed termination caused by uncaught exception when adding MIDI
1023 instrument with PERSISTENT load mode
1024 - fixed possible iterator invalidations when resetting the sampler
1025 - fixed memory leaks when issuing the following LSCP commands:
1030 - fixed possible compilation error when sqlite is not present
1031 - fixed orphaned pointers when setting maximum voices limit (bug #118)
1032 - fixed crash when changing the audio output device of a sampler
1033 channel with loaded instrument and start playing notes
1034 - fixed endless loop in Engine::SuspendAll() (bug #120)
1035 - fixed a low-level atomic load function that was broken on 64-bit
1036 PowerPC, which probably could cause crashes on that platform
1037 - fixed a memory management error which could cause a crash when a
1038 plugin was unloaded
1039 - bugfix: two private structs had the same name, which could cause
1040 problems if the linker chose the wrong constructor
1041 - fixed low-level ConditionServer usage bug that caused lockups on
1042 Windows
1045 Version 0.5.1 (6 December 2007)
1047 * packaging changes:
1048 - added autoconf checks for pthread library
1049 - added autoconf check for pthread bug found on certain NPTL-enabled
1050 glibc versions (see Gentoo bug report #194076)
1051 - added autoconf checks for MS Windows
1053 * general changes:
1054 - bugfix: the thread used by an editor plugin didn't die when the
1055 editor closed
1056 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1057 out all the space. operator--() did not apply size_mask after
1058 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1059 order to avoid problems with the _NonVolatileReader functions.
1060 - bugfix: Stream.h: added a missing divide by BytesPerSample in
1061 GetWriteSpace(). Since this function is currently only used in
1062 the stream's qsort() compare function, it didn't trigger any
1063 bugs.
1064 - Resampler.h, Synthesizer.h: cubic interpolation now works in
1065 24bit mode too. Faster method to read 24bit words on little
1066 endian machines (x86): replaced 3 byte reads + shifts with a 1
1067 unaligned 32bit read and shift
1068 - experimental support for MS Windows (MIDI input via MME, AUDIO
1069 output via ASIO)
1070 - made handling of SIGINT signal (Ctrl-C) a bit more robust
1071 - support for monitoring the total number of active disk streams
1072 (new LSCP commands: GET TOTAL_STREAM_COUNT,
1075 * AUDIO driver:
1076 - added Windows ASIO low latency audio driver
1078 * MIDI driver:
1079 - added MME Windows MIDI driver
1081 * LSCP server:
1082 - added support for Windows style path / filenames, however with
1083 forward slash path separators instead of backslash
1084 (i.e. "C:/foo/bar.gig")
1085 - allow naughty liblscp to send non-string device parameters within
1086 apostrophes as well
1087 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1088 "LIST FILE INSTRUMENTS <file>" and
1089 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1090 about an arbitrary instrument file on the system where the sampler is
1091 running on
1093 Version 0.5.0 (15 October 2007)
1095 * packaging changes:
1096 - config.h is not going to be installed along with liblinuxsampler's
1097 API header files anymore
1098 - only the API relevant header (and source) files will be exported to
1099 the Doxygen API documentation (explicitly listed in Doxyfile.in)
1100 - added completely new XCode project files for Mac OSX which is now
1101 capable to execute our autoconf environment, thus no need anymore
1102 to maintain the compile time configuration file (osx/version.h) for
1103 OSX manually (patch by Toshi Nagata)
1104 - fixed buggy boolean --enable-foo / --disable-foo configure script
1105 parameters
1106 - global.h now only covers global definitions that are needed for the
1107 C++ API header files, all implementation internal global definitions
1108 are now in global_private.h
1109 - atomic.h is not exposed to the C++ API anymore
1110 - no need to include config.h anymore for using LS's API header files
1111 - fixed warnings in API doc generation
1113 * general changes:
1114 - replaced the old, confusing MIDI program change mechanism by a
1115 flexible MIDI instrument mapper which allows to map arbitrary
1116 (MIDI bank, MIDI program) pairs with arbitrary
1117 (engine type, instrument file, file index) triplets which will be
1118 loaded on the respective channel when such MIDI program change
1119 messages arrive, beside that, each entry allows to define a life-time
1120 strategy for the instrument, so the user can define whether the
1121 instrument should i.e. be permanently loaded (to be able to switch
1122 quickly among sounds) or i.e. loaded just on demand when the
1123 respective program change arrives (to safe RAM space), as well as a
1124 global volume factor for each entry, so the user can adjust the volume
1125 dynamic of his mapped instrument collection without having to modify
1126 the instrument files, also one can manage arbitrary amount of such
1127 MIDI instrument maps and assign each sampler channel individually
1128 a certain map, so that i.e. separation of normal instruments and
1129 drumkits is possible
1130 - new notification events for tracking changes to audio/MIDI devices,
1131 MIDI instrument maps, MIDI instruments, FX sends, global volume.
1132 - sampler was limited to load max. 200 instruments in the background
1133 due to a constant size RingBuffer FIFO which is now replaced by a
1134 dynamic (unlimited) size std::list FIFO
1135 - added FX sends, these allow to route audio signals to arbitrary audio
1136 output channels for being processed by external effect processors
1137 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1138 controllers
1139 - global (sampler wide) volume can now be controlled at runtime
1140 - Implemented new, improved notification system
1141 - fixed compilation errors regarding OSX
1142 (patch by Toshi Nagata)
1143 - implemented instruments database
1144 - added support for escape sequences to the instruments database
1145 - added highly experimental support for on-the-fly instrument editing
1146 within the sampler's process (by using instrument editor plugins),
1147 you'll notice the new "Registered instrument editors:" message on
1148 startup, added a new LSCP command:
1149 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1150 to spawn a matching instrument editor for the instrument on the
1151 given sampler channel, the plugin path can be overridden at compile
1152 time with ./configure --enable-plugin-dir=/some/dir
1153 - added experimental code for synchronizing instrument editors hosted
1154 in the sampler's process to safely edit instruments while playing
1155 without a crash (hopefully) by either suspending single regions
1156 wherever possible or if unavoidable whole engine(s)
1157 - fixed several issues in fundamental "Thread" class: set scheduling
1158 policy and priority on thread level, set a minimum stack size for
1159 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1160 threads simply inherited properties of starting thread instead of
1161 setting their own policy and priority
1162 - minor fix in our automatic stack trace mechanism on crashes, the
1163 main process did not wait for the stack trace process to finish
1164 its output
1165 - fixed some minor memory leaks
1166 - reenabled assembly features support, at the moment only for
1167 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1168 - minor assembly fix in x86 features detection (don't use the PIC
1169 register, to avoid relocations in the text segment at runtime)
1170 - POSIX callback functions of Thread.h are hidden
1172 * MIDI driver:
1173 - dispatch bank select (MSB and LSB) messages
1175 * audio driver:
1176 - the ALSA audio output driver parameters now reflect the correct
1177 parameter value ranges for the respective selected sound card
1178 (patch by Till Wimmer, a bit fixed and extended)
1180 * Gigasampler format engine:
1181 - if a filter is used and EG2 finishes before EG1, let the voice
1182 die when EG2 has finished (this fixes a problem with clicks and
1183 voice starvation for some gigs)
1184 - playback is no longer disabled during instrument loading
1185 - all notes playing on a channel that changes its instrument keep
1186 playing with the old instrument until they get a note off
1187 command
1188 - EG fix: a release value of zero could cause noises or crash
1189 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1190 - EG fine tuning: when attack is zero the EG starts at a level
1191 above max sustain level, which means that there is a decay phase
1192 even if sustain is 100%
1193 - more EG fixes: the level could sometimes go below zero and cause
1194 noises or crashes
1195 - minor fix of EGDecay (patch by Toshi Nagata)
1196 - fixed compiler error when --enable-override-filter-type was
1197 supplied to the configure script (fixes #46)
1198 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1199 instead of a fix value
1200 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1201 127 (solo mode) only kill voices if the respective mode really
1202 changed
1204 * LSCP server:
1205 - fixed compile time error for old Bison versions
1206 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1207 - parser now supports extended ASCII character set
1208 (up to ASCII code 255, i.e. includes now umlauts and accents)
1209 - filename arguments in LSCP commands now allow to use escape
1210 sequences, that is directly literal as one of: \', \", \\, \n, \r,
1211 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1212 code value like \xf2) (fixes bug #24)
1213 - the following LSCP commands now also support escape sequences for at
1214 least one of their text-based parameters (i.e. name, description):
1221 - returns verbose syntax errors (line and column where syntax error
1222 occured, the unexpected character and the actually expected, possible
1223 character(s), the latter only if less than 5 possibilities)
1224 - made sure that LSCP syntax is not affected by gigedit locale
1225 settings
1226 - bugfix regarding strings parameter lists: all comma separated lists
1227 of strings were treated as being one string containing commas
1228 (fixes #57)
1230 * Bug fixes:
1231 - fixed crash occurring on certain LSCP scripts (Bug 39)
1232 - another thread safety fix for lscp "load engine" and "set
1233 channel audio output device"
1234 - fixed a crash which occurs when reassigning the same engine
1235 on a sampler channel with connected MIDI device
1236 - fixed a crash which occurs when changing the number of ports of a MIDI
1237 device connected to a sampler channel to number less then or equal
1238 to the index of the port to which the sampler channel is connected.
1239 - The previous bindings were not been disconnected when altering
1240 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1241 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1242 - The active stream/voice count statistic was incorrect.
1243 - notification events were not been sent for some sampler
1244 channel changes
1245 - added default min and max values to restrict the number of allowed
1246 audio output channels and MIDI input ports
1247 - the connection to the PCM interface is now closed when destroying
1248 an audio output device
1249 - files with slash in their path or filename could not be loaded
1251 * test cases:
1252 - updated and fixed (haven't been touched in a while)
1254 Version 0.4.0 (24 November 2006)
1256 * packaging changes:
1257 - changed deprecated copyright attribute to license; added ldconfig
1258 to post-(un)install steps; added devel package for liblinuxsampler;
1259 to linuxsampler.spec (RPM)
1260 - install necessary development header files for allowing 3rd party
1261 applications to link against liblinuxsampler
1262 - liblinuxsampler's API documentation can be generated with 'make docs'
1263 (Doxygen required)
1264 - added benchmark to automatically detect the best triangle LFO
1265 implementation (currently either an integer math solution or a
1266 di-harmonic approximation), automatic detection can be overriden
1267 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1268 configure script argument though (mandatory for cross-compilation)
1269 - do not automatically pick optimized gcc flags if the user already
1270 provided some on his own (as CXXFLAGS)
1271 - added compile time option to disable processing of All-Notes-Off MIDI
1272 messages
1273 - added compile time options to allow disabling the various audio and
1274 MIDI drivers
1275 - fixed automatic GCC CPU switch detection on PPC
1276 (patch by Ebrahim Mayat)
1278 * Gigasampler format engine:
1279 - extensive synthesis optimization
1280 (reimplementation of EGs and LFO(s), removed synthesis parameter
1281 prerendering and the synthesis parameter matrix in general, splitting
1282 each audio fragment into subfragments now where each subfragment uses
1283 constant pitch and filter coefficients. The volume coefficient is
1284 linearly interpolated inside a subfragment, unless
1285 --disable-interpolate-volume is set.)
1286 - fine tuning of the EG modulation parameters
1287 - improved filter cutoff calculation by adding support for the
1288 following gig parameters: Cutoff freq (used when no cutoff
1289 controller is defined), Control invert, Minimum cutoff, Velocity
1290 curve and Velocity range. The keyboard tracking now scales
1291 cutoff frequency instead of resonance.
1292 - added support for gig parameter Resonance.
1293 - fixed bug in sysex handling (patch by Juan Linietsky)
1294 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1295 which can be overridden with --enable-global-attenuation
1296 - EG fixes: made the length of "attack hold" stage more
1297 accurate. Release stage can now start before attack stage
1298 ends. Cancel release didn't work when sustain was zero. Attack
1299 time now has a minimal value to prevent clicks.
1300 - fixed pitch changes larger than one octave
1301 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1302 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1303 all modes can be altered via standard GM messages, that is CC5 for
1304 altering portamento time, CC65 for enabling / disabling portamento
1305 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1306 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1307 parameter) and crossfade
1308 - added support for the "attenuation controller threshold" gig
1309 parameter
1310 - added smoothing of volume changes caused by control change
1311 messages
1312 - sample loop parameters are now taken from the DimensionRegion
1313 instead of the wave chunk
1314 - fixed keyswitching for v3 gigs with a number of keyswitch splits
1315 not equal to a power of two
1316 - reimplementation of the filter algorithm. The new filter is more
1317 accurate and supports all gig filter types, including bandreject
1318 and lowpass turbo.
1319 - real support for 24 bit samples - samples are not truncated to
1320 16 bits anymore
1321 - support for aftertouch (channel pressure, not polyphonic
1322 aftertouch)
1323 - LFO1 behaviour fixed (dampening from max volume instead of
1324 amplifying from 0)
1326 * LSCP server:
1327 - fixed application exit on broken pipe error (fixes bug #20)
1328 - fixed the notification messages delay due to lack of
1329 network activity (fixes bug #26)
1330 - fixed parser bug which occured on space(s) within device parameters
1333 * audio driver:
1334 - added aRts audio output driver (by no means RT safe)
1336 * MIDI driver:
1337 - fixed legacy sysex code which caused dispatching of MIDI SysEx
1338 messages several times instead of once
1339 - API extension for MIDI drivers which already supply exact time stamps
1340 for events (i.e. for offline rendering based MIDI drivers)
1341 - added checks for bad MIDI data
1343 * linuxsampler application:
1344 - show available sampler engine types on startup
1346 * general changes:
1347 - support for muting sampler channels and solo mode of the same, two new
1348 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1349 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1350 introduced for this, the behavior is the same like on a mixer console
1351 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1352 --enable-process-muted-channels which can be used to enable the
1353 processing of muted channels.
1354 - support for sostenuto pedal
1355 - support for monitoring the total number of active voices
1358 - fixed some memory management errors
1359 - fixed some concurrency problems that could lead to crashes when
1360 LSCP commands were executed
1361 - fixed crash when instrument loading failed previously on the same
1362 sampler channel (fixes bug #36)
1364 Version 0.3.3 (15 July 2005)
1366 * packaging changes:
1367 - fixed compilation with gcc 4.0
1369 * Gigasampler format engine:
1370 - LFO preprocessing was performed even though the respective LFO was
1371 disabled by the instrument patch (minor efficiency fix)
1372 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1373 for volume ramp downs in the same fragment (needed for current voice
1374 stealing implementation) then simply inform the user with a warning
1375 about possible click sounds and reduce the volume ramp down
1376 appropriately instead of cancelling the audio device connection
1378 Version 0.3.2 (24 June 2005)
1380 * packaging changes:
1381 - updated autotools build files to compile on OS X
1382 (conditional compilation of CoreMIDI and MidiShare drivers)
1383 - hand-crafted assembly optimization code can be disabled with
1384 './configure --disable-asm' (definitely not recommended)
1385 - fixed 'make dist' rule to include all necessary files
1386 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1387 (due to 'dist-bzip2' automake option)
1389 * Gigasampler format engine:
1390 - support for the gig parameters for "release velocity response" curves
1391 - fine tuning of the EGADSR envelope
1392 - volume of release triggered samples now depends on note-on velocity,
1393 note length and gig parameter "release trigger decay" instead of
