* Only play release trigger samples on sustain pedal up if this behaviour
  was explicitly requested by the instrument (otherwise only on note-off).
* Bumped version (2.1.0.svn2).

1 Version SVN trunk (?)
2
3 * Real-time instrument scripts:
4 - Fixed behavior of built-in NKSP functions change_sustain(),
5 change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain()
6 and change_cutoff_release().
7
8 * general changes:
9 - Only play release trigger samples on sustain pedal up if this behaviour
10 was explicitly requested by the instrument (otherwise only on note-off).
11
12 Version 2.1.0 (25 Nov 2017)
13
14 * SFZ format engine:
15 - added support for <global>, <master> and #define (patch by Alby M)
16 - Removed code duplication in SFZ file loading code.
17 - Added support for sfz extension opcode 'script' which may be used to
18 load real-time instrument script file (NKSP script language).
19 - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
20 - Fixed unintended volume fade-in of voices under certain conditions.
21 - sfz parser: allow missing space between header and opcode
22
23 * Gigasampler/GigaStudio format engine:
24 - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
25 cutoff settings.
26 - Got rid of resembling an ancient GSt misbehavior which did not pitch at
27 all if an up-pitch of more than 40 semi tones was requested (I don't
28 think there is any stock gig sound that requires this behavior to
29 resemble its original sound).
30 - Added support for controlling whether the individual EGADSR stages may
31 be aborted (as LinuxSampler extension to the original GigaStudio 4
32 format).
33
34 * general changes:
35 - fixed printf type errors (mostly in debug messages)
36 - use unique_ptr instead of auto_ptr when building with C++11
37 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
38 allowing to sort data efficiently in real-time safe manner.
39 - RTList class: added methods for moving/inserting elements to arbitrary
40 position within a list.
41 - RTList class: added method fromPtr() for creating an Iterator object from
42 a raw element pointer.
43 - Attempt to partly fix resetting engine channels vs. resetting engine, an
44 overall cleanup of the Reset*(), ConnectAudioDevice(),
45 DisconnectAudioDevice() API methods would still be desirable though,
46 because the current situation is still inconsistent and error prone.
47 - Active voices are now internally grouped to "Note" objects, instead of
48 being directly assigned to a keyboard key. This allows more fine graded
49 processing of voices, which is i.e. required for certain instrument
50 script features.
51 - Fix: Release trigger voices were not spawned on sustain pedal up
52 (CC #64) events.
53 - Fix: Release trigger voices can now also distinguish correctly between
54 note-off and sustain pedal up events.
55 - All engines: Increased ramp speed of volume smoother and pan smoother
56 (while slow rate of crossfade smoother is preserved) to allow quick
57 volume and pan changes by instrument scripts for instance.
58 - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
59 properly and thus were ignored for certain uses.
60 - Added new C++ API method
61 VirtualMidiDevice::SendChannelPressureToSampler().
62 - windows, 32-bit: fixed potential crashes by making sure the stack in
63 sub threads is 16-byte aligned
64 - fixed numerous compiler warnings
65 - Fixed invalid (note-on) event ID being assigned to new Note objects.
66 - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
67 fixes potential undefined behavior.
68 - Fixed Note object leak when triggering notes on keys which did not
69 have a valid sample mapped (fixes bug #252).
70 - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
71 - linuxsampler binary fix: option --create-instruments-db ignored
72 subsequent optional argument due to glibc's implementation oddity
73 which expects a "=" sign, but no space between them.
74
75 * packaging changes:
76 - removed unnecessary dependency to libuuid
77 (originated by libgig's usage of it)
78 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
79 auto detect whether it (sh/c)ould output its messages in color.
80 - Debian: Fixed packaging error about invalid "Source-Version"
81 substitution variable.
82 - Debian: Raised Debian compatibility level to Debian 9 "Stretch".
83 - Debian: Added build dependency to libsqlite3-dev for building
84 linuxsampler with instruments DB support.
85
86 * Real-time instrument scripts:
87 - Implemented scheduler for delayed MIDI events and for suspended scripts.
88 - Built-in script function "wait()": implemented support for function's
89 "duration-us" argument, thus scripts using this function are now
90 correctly resumed after the requested amount of microseconds.
91 - Built-in script function "play_note()": implemented support for
92 function's "duration-us" argument, thus notes triggered with this
93 argument are now correctly released after the requested amount of
94 microseconds.
95 - Fix: script events were not cleared when engine channel was reset,
96 potentially causing undefined behavior.
97 - Fixed crash which happened when trying to reference an undeclared
98 variable.
99 - Built-in script function "play_note()": Added support for passing
100 special value -1 for "duration-us" argument, which will cause the
101 triggered note to be released once the original note was released.
102 - Instrument script classes now exported with the liblinuxsampler C++ API.
103 - Added new API method ScriptVM::syntaxHighlighting() which provides
104 a convenient syntax highlighting backend for external instrument
105 script editor applications.
106 - Added new C++ API class "ScriptVMFactory".
107 - Extended parser issues to provide not only first line and first
108 column, but also last line and last column of issue (thus marking
109 the precise span of the issue within the source code).
110 - Reload script automatically after being modified by an instrument
111 editor.
112 - NKSP language grammar correction: allow empty event handler bodies
113 like "on note end on".
114 - Implemented built-in script function "change_vol()".
115 - Implemented built-in script function "change_tune()".
116 - Implemented built-in script function "change_pan()".
117 - Implemented built-in script function "change_cutoff()".
118 - Implemented built-in script function "change_reso()".
119 - Implemented built-in script function "event_status()".
120 - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
121 "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
122 "event_status()" function.
123 - NKSP language: Added support for bitwise operators ".or.", ".and."
124 and ".not.".
125 - NKSP language scanner: Fixed IDs matching to require at least one
126 character (i.e. when matching function names or variable names).
127 - NKSP language scanner: disabled unusued rules.
128 - Fixed behavior of play_note() and note_off() functions which must
129 be distinguished engine internally from "real" MIDI note on/off
130 events in order to avoid misbehaviors like hanging notes.
131 - Implemented built-in script variable "$KSP_TIMER".
132 - Implemented built-in script variable "$NKSP_REAL_TIMER".
133 - Implemented built-in script variable "$NKSP_PERF_TIMER".
134 - Implemented built-in script variable "$ENGINE_UPTIME".
135 - Implemented built-in script function "inc()".
136 - Implemented built-in script function "dec()".
137 - NKSP language fix: division expressions were evaluated too often.
138 - NKSP language fix: string concatenation operator was right
139 associative instead of left (to right).
140 - NKSP language correction: allow empty statements in entire language
141 (i.e. "if end if").
142 - Implemented built-in script function "stop_wait()".
143 - Implemented built-in script variable "$NI_CALLBACK_ID".
144 - Implemented built-in script variable "$NI_CALLBACK_TYPE".
145 - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
146 - Added support for read-only built-in variables (respectively
147 handled by the script parser).
148 - Added built-in script constant "$NI_CB_TYPE_INIT".
149 - Added built-in script constant "$NI_CB_TYPE_NOTE".
150 - Added built-in script constant "$NI_CB_TYPE_RELEASE".
151 - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".
152 - NKSP Language: Added support for user defined script functions.
153 - Implemented built-in script function "change_attack()".
154 - Implemented built-in script function "change_decay()".
155 - Implemented built-in script function "change_release()".
156 - Fixed all change_*() built-in script functions to apply their
157 synthesis parameter changes immediately in case the respective note
158 was triggered at the same time, instead of scheduling the parameter
159 change, especially because it would cause some parameter types's
160 changes either to be ramped (i.e. change_vol()) or other types even
161 to have not effect at all (i.e. change_attack()).
162 - Implemented built-in script function "sh_left()".
163 - Implemented built-in script function "sh_right()".
164 - Implemented built-in script function "min()".
165 - Implemented built-in script function "max()".
166 - NKSP Fix: "init" event handler was not always executed when a script
167 was loaded.
168 - NKSP built-in wait() script function: abort script execution if
169 a negative or zero wait time was passed as argument (since this is
170 a common indication of a bug either of the script or even of the
171 engine, which could lead to RT instability or even worse).
172 - ScriptVM: Implemented automatic suspension of RT safety
173 threatening scripts.
174 - Provide more user friendly error messages on syntax errors.
175 - Fixed NKSP parser warning "Not a statement" when assigning an
176 initializer list to an array variable.

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

274
275 * Instruments DB:
276 - Fixed memory access bug of general DB access code which lead to
277 undefined behavior.
278 - Cleanup of instruments DB file creation and opening code.
279 - The instrument DB path of linuxsampler's --create-instruments-db argument
280 is now optional, if it is missing, then a default location is used.
281 - Added support for scanning SFZ (.sfz) files.
282 - Added support for scanning Sound Font (.sf2) files.
283 - Fixed undefined DB transaction behavior.
284

290 - Mac OS X: fixed building outside source directory
291 - made sure all source files for hostplugins are included when
292 doing "make dist"
293 - removed empty directories left from the cvs to svn migration
294 - fixed compilation with gcc 4.6.1
295 - another "make dist" fix, for the LV2 plugin
296 - made --enable-pthread-testcancel default on Mac OS X

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

819 (fixes #208)
820 - Fixed bug in LSCP grammar definition which caused a statement like
821 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
822 practically irrelevant, however it caused problems with the new LSCP
823 shell's auto completion feature).
824 - Fixed MIDI program change messages being ignored if quickly executed
825 after each other (fixes #231).

857 unnecessarily long after an update
858 - added support for notifying instrument editors on note-on / note-off
859 events (e.g. to highlight the pressed keys on the virtual keyboard
860 of gigedit)
861 - added support for triggering notes by instrument editors (see above)
862 - be verbose on DLL load errors (on Linux)
863 - fixed di-harmonic triangle LFO implementation (this LFO implementation
864 is only used by very few systems, most pick the int math
865 implementation, which is usually faster)
866 - fixes for audio drivers with varying buffer sizes
867 - experimental support for running LinuxSampler as a DSSI, LV2 and
868 VST plugin
869 - notification events for stream/voice count statistics are now sent
870 only when there are actual changes
871 - added memory ordering constraints to improve stability on
872 multi-core and multi-cpu systems
873 - maximum voices and disk streams can now be altered at runtime
874 - fixed CPU feature detection on x86_64 (maybe fixes #108)
875 - automatic stacktrace mechanism is now turned off by default and can
876 be switched on by command line option "--stacktrace" (the automatic
877 stacktrace mechanism seems to be broken on most systems at the moment)
878 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
879 a pointer to the launched InstrumentEditor object
880 - added optional 3rd party user data parameter for following
881 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
882 InstrumentEditor::Launch(),
883 InstrumentManager::LaunchInstrumentEditor()
884 - theoretical fix: made SynchronizedConfig follow C++0x memory
885 model more strictly
886 - fixes for using large audio device buffers
887 - Windows: add the installation directory to the DLL search path
888 when loading an editor plugin (solves problems with VST and
889 gigedit on systems with other GTK versions installed)
890 - updated linuxsampler man page
891
892 * audio driver:
893 - removed the nonsense audio channel constraint (which was hard coded to
894 max. 100 audio channels) for most audio drivers
895 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
896 opposed to the LSCP specs
897 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
898 reflected the wrong value
899 - fixed a memory management bug in ASIO driver
900 - Makefile fix: JACK_CFLAGS wasn't used
901 - JACK: use jack_client_open instead of the deprecated
902 jack_client_new
903 - added (experimental) CoreAudio driver
904 - applied old fixes to the ASIO driver that were included in the
905 previous binary release but accidentally never committed to CVS
906 (fixes #117)
907 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
908 win64)
909 - VST: added support for sample rate and buffer size changes
910 - VST: close editor (Fantasia) when the VST is removed
911 - VST: avoid opening Fantasia more than once for each VST instance
912 - VST: export main function as "main" on Linux too (fix for
913 energyXT)
914 - VST: changed number of output channels from one stereo to 16
915 stereo
916 - added channel routing, fxsends and midi maps to the settings
917 stored in the plugin state
918 - performance optimization of AudioChannel::MixTo() and
919 AudioChannel::CopyTo() methods using GCC vector exensions
920 (if available)
921 - ASIO fixes: avoid initializing the device twice, avoid throwing
922 exception when getting parameters from a disconnected device
923
924 * MIDI driver:
925 - added JACK MIDI driver
926 - dispatch bank select as ordinary CC as well, the user might seriously
927 want to (mis)use it for some purpose ("fixed" in all current MIDI
928 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
929 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
930 CoreMidi or AU
931 - fixed mingw-w64 compilation error in MME driver
932 - made program change handling in MIDI thread real-time safe by
933 moving the logic to a non-RT thread
934 - fixed minor memory leak in ALSA driver
935
936 * instruments database:
937 - avoid time consuming samples scanning when adding instruments
938 to the instruments database
939 - added support for handling lost files in the instruments database
940 - Implemented option for adding instruments in separate directories
941 in the instruments database
942 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
943 - work-around for missing fnmatch function on Windows to make
944 instrument database compilable
945 - added instrument database support on Windows
946 works with both standalone mode and VST plugin.
947 the instruments DB file is located in
948 %USERPROFILE%\.linuxsampler\instruments.db which allows different
949 databases for each windows user
950 if no DB is present it automatically creates the .linuxsampler subdir
951 and then creates an empty DB
952 - fixed recursive import, which was broken on Windows
953
954 * Gigasampler format engine:
955 - fixed a memory leak that could happen when a channel was deleted
956 while notes were playing
957 - made it possible to load an instrument even if the audio thread
958 isn't running
959 - added partial support for the "Controller Triggered" MIDI rule,
960 enough for piano gigs with pedal noise samples
961 - minor fix: only mark FX sends as being modified if really the
962 respective FX send MIDI controller was used
963 - added support for GM global device volume SysEx message
964 (can be selected at compile time to either apply globally to the
965 whole sampler [default] or only to the sampler channels that are
966 connected to the respective MIDI input port the SysEx message arrived
967 on)
968 - bugfix: notes triggered at position 0 in the audio buffer were
969 sometimes wrongly killed in the same buffer, causing no sound to
970 be played
971 - added support for chromatic / drumkit mode Roland GS Sysex message
972 which is usally used to switch a part between chromatic sounds and
973 drumkit sounds (as opposed to their common default setting of MIDI
974 part 10 being a drumkit part and all other ones chromatic parts), in
975 LS however one can switch between the first 16 MIDI instrument maps
976 defined for the sampler
977 - made it possible to create multiple sample channels even if the
978 audio thread isn't running
979 - fixed crash when removing channel with active voices (#116)
980 - bugfix: on sample reference changes (instrument editor), only
981 un-cache the respective sample if it's really not used by any
982 sampler engine anymore
983 - re-cache samples in case they were changed by an instrument editor,
984 e.g. when a sample was added while playing (#82)
985 - fixed hanging notes which occured when note-off event had the exact
986 same time stamp as the voice's note-on event and occured both in the
987 same audio fragment cycle (fixes bug #112)
988 - added support for the "fine tune" and "pitch bend range"
989 instrument-level gig parameters
990 - fixed minor artifacts in pitch bend handling
991 - added support for GS Reset SysEx message
992 - allow gig files to use unlimited downward pitch shifting
993 - added a limit check for upward pitch shifting
994 - bugfix: sometimes, when playing a note twice fast, the second
995 note was silent
996 - fixed crash happening when a pitch bend event arrived at the
997 same time a new instrument was loading
998
999 * LSCP server:
1000 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
1001 react on MIDI data arriving on certain sampler channels (so far only
1002 Note-On and Note-Off events are sent via this LSCP event)
1003 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1004 react on MIDI data arriving on certain MIDI input devices (so far only
1005 Note-On and Note-Off events are sent via this LSCP event)
1006 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
1007 SET DB_INSTRUMENT FILE_PATH
1008 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
1009 frontends to send MIDI messages to specific sampler channel
1010 - added two additional fields to GET FILE INSTRUMENT INFO command -
1011 KEY_BINDINGS and KEYSWITCH_BINDINGS
1012 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1013 was incorrect
1014 - Optimized the retrieval of the MIDI instrument mappings
1015 - added new LSCP command "SET VOICES" to globally alter the maximum
1016 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1017 be triggered respectively
1018 - added new LSCP command "SET STREAMS" to globally alter the maximum
1019 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1020 which will be triggered respectively
1021 - bugfix: retry if "select" returns EINTR (this fixes a crash when
1022 a gigedit file dialog is opened)
1023 - close all connections when LSCPServer is deleted
1024 - hard close of all sockets on exit
1025 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
1026 driver
1027
1028 * Bug fixes:
1029 - fixed a crash which occurs when removing a sampler channel waiting
1030 to start instrument loading after another channel
1031 - fixed a crash which occurs when removing a sampler channel with
1032 instrument loading in progress (bug #113)
1033 - fixed termination caused by uncaught exception when adding MIDI
1034 instrument with PERSISTENT load mode
1035 - fixed possible iterator invalidations when resetting the sampler
1036 - fixed memory leaks when issuing the following LSCP commands:
1037 GET AUDIO_OUTPUT_DRIVER INFO
1038 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
1039 GET MIDI_INPUT_DRIVER INFO
1040 GET MIDI_INPUT_DRIVER_PARAMETER INFO
1041 - fixed possible compilation error when sqlite is not present
1042 - fixed orphaned pointers when setting maximum voices limit (bug #118)
1043 - fixed crash when changing the audio output device of a sampler
1044 channel with loaded instrument and start playing notes
1045 - fixed endless loop in Engine::SuspendAll() (bug #120)
1046 - fixed a low-level atomic load function that was broken on 64-bit
1047 PowerPC, which probably could cause crashes on that platform
1048 - fixed a memory management error which could cause a crash when a
1049 plugin was unloaded
1050 - bugfix: two private structs had the same name, which could cause
1051 problems if the linker chose the wrong constructor
1052 - fixed low-level ConditionServer usage bug that caused lockups on
1053 Windows
1054
1055
1056 Version 0.5.1 (6 December 2007)
1057
1058 * packaging changes:
1059 - added autoconf checks for pthread library
1060 - added autoconf check for pthread bug found on certain NPTL-enabled
1061 glibc versions (see Gentoo bug report #194076)
1062 - added autoconf checks for MS Windows
1063
1064 * general changes:
1065 - bugfix: the thread used by an editor plugin didn't die when the
1066 editor closed
1067 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1068 out all the space. operator--() did not apply size_mask after
1069 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1070 order to avoid problems with the _NonVolatileReader functions.
1071 - bugfix: Stream.h: added a missing divide by BytesPerSample in
1072 GetWriteSpace(). Since this function is currently only used in
1073 the stream's qsort() compare function, it didn't trigger any
1074 bugs.
1075 - Resampler.h, Synthesizer.h: cubic interpolation now works in
1076 24bit mode too. Faster method to read 24bit words on little
1077 endian machines (x86): replaced 3 byte reads + shifts with a 1
1078 unaligned 32bit read and shift
1079 - experimental support for MS Windows (MIDI input via MME, AUDIO
1080 output via ASIO)
1081 - made handling of SIGINT signal (Ctrl-C) a bit more robust
1082 - support for monitoring the total number of active disk streams
1083 (new LSCP commands: GET TOTAL_STREAM_COUNT,
1084 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1085
1086 * AUDIO driver:
1087 - added Windows ASIO low latency audio driver
1088
1089 * MIDI driver:
1090 - added MME Windows MIDI driver
1091
1092 * LSCP server:
1093 - added support for Windows style path / filenames, however with
1094 forward slash path separators instead of backslash
1095 (i.e. "C:/foo/bar.gig")
1096 - allow naughty liblscp to send non-string device parameters within
1097 apostrophes as well
1098 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1099 "LIST FILE INSTRUMENTS <file>" and
1100 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1101 about an arbitrary instrument file on the system where the sampler is
1102 running on
1103
1104 Version 0.5.0 (15 October 2007)
1105
1106 * packaging changes:
1107 - config.h is not going to be installed along with liblinuxsampler's
1108 API header files anymore
1109 - only the API relevant header (and source) files will be exported to
1110 the Doxygen API documentation (explicitly listed in Doxyfile.in)
1111 - added completely new XCode project files for Mac OSX which is now
1112 capable to execute our autoconf environment, thus no need anymore
1113 to maintain the compile time configuration file (osx/version.h) for
1114 OSX manually (patch by Toshi Nagata)
1115 - fixed buggy boolean --enable-foo / --disable-foo configure script
1116 parameters
1117 - global.h now only covers global definitions that are needed for the
1118 C++ API header files, all implementation internal global definitions
1119 are now in global_private.h
1120 - atomic.h is not exposed to the C++ API anymore
1121 - no need to include config.h anymore for using LS's API header files
1122 - fixed warnings in API doc generation
1123
1124 * general changes:
1125 - replaced the old, confusing MIDI program change mechanism by a
1126 flexible MIDI instrument mapper which allows to map arbitrary
1127 (MIDI bank, MIDI program) pairs with arbitrary
1128 (engine type, instrument file, file index) triplets which will be
1129 loaded on the respective channel when such MIDI program change
1130 messages arrive, beside that, each entry allows to define a life-time
1131 strategy for the instrument, so the user can define whether the
1132 instrument should i.e. be permanently loaded (to be able to switch
1133 quickly among sounds) or i.e. loaded just on demand when the
1134 respective program change arrives (to safe RAM space), as well as a
1135 global volume factor for each entry, so the user can adjust the volume
1136 dynamic of his mapped instrument collection without having to modify
1137 the instrument files, also one can manage arbitrary amount of such
1138 MIDI instrument maps and assign each sampler channel individually
1139 a certain map, so that i.e. separation of normal instruments and
1140 drumkits is possible
1141 - new notification events for tracking changes to audio/MIDI devices,
1142 MIDI instrument maps, MIDI instruments, FX sends, global volume.
1143 - sampler was limited to load max. 200 instruments in the background
1144 due to a constant size RingBuffer FIFO which is now replaced by a
1145 dynamic (unlimited) size std::list FIFO
1146 - added FX sends, these allow to route audio signals to arbitrary audio
1147 output channels for being processed by external effect processors
1148 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1149 controllers
1150 - global (sampler wide) volume can now be controlled at runtime
1151 - Implemented new, improved notification system
1152 - fixed compilation errors regarding OSX
1153 (patch by Toshi Nagata)
1154 - implemented instruments database
1155 - added support for escape sequences to the instruments database
1156 - added highly experimental support for on-the-fly instrument editing
1157 within the sampler's process (by using instrument editor plugins),
1158 you'll notice the new "Registered instrument editors:" message on
1159 startup, added a new LSCP command:
1160 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1161 to spawn a matching instrument editor for the instrument on the
1162 given sampler channel, the plugin path can be overridden at compile
1163 time with ./configure --enable-plugin-dir=/some/dir
1164 - added experimental code for synchronizing instrument editors hosted
1165 in the sampler's process to safely edit instruments while playing
1166 without a crash (hopefully) by either suspending single regions
1167 wherever possible or if unavoidable whole engine(s)
1168 - fixed several issues in fundamental "Thread" class: set scheduling
1169 policy and priority on thread level, set a minimum stack size for
1170 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1171 threads simply inherited properties of starting thread instead of
1172 setting their own policy and priority
1173 - minor fix in our automatic stack trace mechanism on crashes, the
1174 main process did not wait for the stack trace process to finish
1175 its output
1176 - fixed some minor memory leaks
1177 - reenabled assembly features support, at the moment only for
1178 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1179 - minor assembly fix in x86 features detection (don't use the PIC
1180 register, to avoid relocations in the text segment at runtime)
1181 - POSIX callback functions of Thread.h are hidden
1182
1183 * MIDI driver:
1184 - dispatch bank select (MSB and LSB) messages
1185
1186 * audio driver:
1187 - the ALSA audio output driver parameters now reflect the correct
1188 parameter value ranges for the respective selected sound card
1189 (patch by Till Wimmer, a bit fixed and extended)
1190
1191 * Gigasampler format engine:
1192 - if a filter is used and EG2 finishes before EG1, let the voice
1193 die when EG2 has finished (this fixes a problem with clicks and
1194 voice starvation for some gigs)
1195 - playback is no longer disabled during instrument loading
1196 - all notes playing on a channel that changes its instrument keep
1197 playing with the old instrument until they get a note off
1198 command
1199 - EG fix: a release value of zero could cause noises or crash
1200 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1201 - EG fine tuning: when attack is zero the EG starts at a level
1202 above max sustain level, which means that there is a decay phase
1203 even if sustain is 100%
1204 - more EG fixes: the level could sometimes go below zero and cause
1205 noises or crashes
1206 - minor fix of EGDecay (patch by Toshi Nagata)
1207 - fixed compiler error when --enable-override-filter-type was
1208 supplied to the configure script (fixes #46)
1209 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1210 instead of a fix value
1211 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1212 127 (solo mode) only kill voices if the respective mode really
1213 changed
1214
1215 * LSCP server:
1216 - fixed compile time error for old Bison versions
1217 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1218 - parser now supports extended ASCII character set
1219 (up to ASCII code 255, i.e. includes now umlauts and accents)
1220 - filename arguments in LSCP commands now allow to use escape
1221 sequences, that is directly literal as one of: \', \", \\, \n, \r,
1222 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1223 code value like \xf2) (fixes bug #24)
1224 - the following LSCP commands now also support escape sequences for at
1225 least one of their text-based parameters (i.e. name, description):
1226 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1227 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1228 "SET DB_INSTRUMENT_DIRECTORY NAME",
1229 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1230 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1231 "FIND DB_INSTRUMENT_DIRECTORIES"
1232 - returns verbose syntax errors (line and column where syntax error
1233 occured, the unexpected character and the actually expected, possible
1234 character(s), the latter only if less than 5 possibilities)
1235 - made sure that LSCP syntax is not affected by gigedit locale
1236 settings
1237 - bugfix regarding strings parameter lists: all comma separated lists
1238 of strings were treated as being one string containing commas
1239 (fixes #57)
1240
1241 * Bug fixes:
1242 - fixed crash occurring on certain LSCP scripts (Bug 39)
1243 - another thread safety fix for lscp "load engine" and "set
1244 channel audio output device"
1245 - fixed a crash which occurs when reassigning the same engine
1246 on a sampler channel with connected MIDI device
1247 - fixed a crash which occurs when changing the number of ports of a MIDI
1248 device connected to a sampler channel to number less then or equal
1249 to the index of the port to which the sampler channel is connected.
1250 - The previous bindings were not been disconnected when altering
1251 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1252 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1253 - The active stream/voice count statistic was incorrect.
1254 - notification events were not been sent for some sampler
1255 channel changes
1256 - added default min and max values to restrict the number of allowed
1257 audio output channels and MIDI input ports
1258 - the connection to the PCM interface is now closed when destroying
1259 an audio output device
1260 - files with slash in their path or filename could not be loaded
1261
1262 * test cases:
1263 - updated and fixed (haven't been touched in a while)
1264
1265 Version 0.4.0 (24 November 2006)
1266
1267 * packaging changes:
1268 - changed deprecated copyright attribute to license; added ldconfig
1269 to post-(un)install steps; added devel package for liblinuxsampler;
1270 to linuxsampler.spec (RPM)
1271 - install necessary development header files for allowing 3rd party
1272 applications to link against liblinuxsampler
1273 - liblinuxsampler's API documentation can be generated with 'make docs'
1274 (Doxygen required)
1275 - added benchmark to automatically detect the best triangle LFO
1276 implementation (currently either an integer math solution or a
1277 di-harmonic approximation), automatic detection can be overriden
1278 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1279 configure script argument though (mandatory for cross-compilation)
1280 - do not automatically pick optimized gcc flags if the user already
1281 provided some on his own (as CXXFLAGS)
1282 - added compile time option to disable processing of All-Notes-Off MIDI
1283 messages
1284 - added compile time options to allow disabling the various audio and
1285 MIDI drivers
1286 - fixed automatic GCC CPU switch detection on PPC
1287 (patch by Ebrahim Mayat)
1288
1289 * Gigasampler format engine:
1290 - extensive synthesis optimization
1291 (reimplementation of EGs and LFO(s), removed synthesis parameter
1292 prerendering and the synthesis parameter matrix in general, splitting
1293 each audio fragment into subfragments now where each subfragment uses
1294 constant pitch and filter coefficients. The volume coefficient is
1295 linearly interpolated inside a subfragment, unless
1296 --disable-interpolate-volume is set.)
1297 - fine tuning of the EG modulation parameters
1298 - improved filter cutoff calculation by adding support for the
1299 following gig parameters: Cutoff freq (used when no cutoff
1300 controller is defined), Control invert, Minimum cutoff, Velocity
1301 curve and Velocity range. The keyboard tracking now scales
1302 cutoff frequency instead of resonance.
1303 - added support for gig parameter Resonance.
1304 - fixed bug in sysex handling (patch by Juan Linietsky)
1305 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1306 which can be overridden with --enable-global-attenuation
1307 - EG fixes: made the length of "attack hold" stage more
1308 accurate. Release stage can now start before attack stage
1309 ends. Cancel release didn't work when sustain was zero. Attack
1310 time now has a minimal value to prevent clicks.
1311 - fixed pitch changes larger than one octave
1312 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1313 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1314 all modes can be altered via standard GM messages, that is CC5 for
1315 altering portamento time, CC65 for enabling / disabling portamento
1316 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1317 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1318 parameter) and crossfade
1319 - added support for the "attenuation controller threshold" gig
1320 parameter
1321 - added smoothing of volume changes caused by control change
1322 messages
1323 - sample loop parameters are now taken from the DimensionRegion
1324 instead of the wave chunk
1325 - fixed keyswitching for v3 gigs with a number of keyswitch splits
1326 not equal to a power of two
1327 - reimplementation of the filter algorithm. The new filter is more
1328 accurate and supports all gig filter types, including bandreject
1329 and lowpass turbo.
1330 - real support for 24 bit samples - samples are not truncated to
1331 16 bits anymore
1332 - support for aftertouch (channel pressure, not polyphonic
1333 aftertouch)
1334 - LFO1 behaviour fixed (dampening from max volume instead of
1335 amplifying from 0)
1336
1337 * LSCP server:
1338 - fixed application exit on broken pipe error (fixes bug #20)
1339 - fixed the notification messages delay due to lack of
1340 network activity (fixes bug #26)
1341 - fixed parser bug which occured on space(s) within device parameters
1342 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1343
1344 * audio driver:
1345 - added aRts audio output driver (by no means RT safe)
1346
1347 * MIDI driver:
1348 - fixed legacy sysex code which caused dispatching of MIDI SysEx
1349 messages several times instead of once
1350 - API extension for MIDI drivers which already supply exact time stamps
1351 for events (i.e. for offline rendering based MIDI drivers)
1352 - added checks for bad MIDI data
1353
1354 * linuxsampler application:
1355 - show available sampler engine types on startup
1356
1357 * general changes:
1358 - support for muting sampler channels and solo mode of the same, two new
1359 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1360 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1361 introduced for this, the behavior is the same like on a mixer console
1362 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1363 --enable-process-muted-channels which can be used to enable the
1364 processing of muted channels.
1365 - support for sostenuto pedal
1366 - support for monitoring the total number of active voices
1367 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1368 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1369 - fixed some memory management errors
1370 - fixed some concurrency problems that could lead to crashes when
1371 LSCP commands were executed
1372 - fixed crash when instrument loading failed previously on the same
1373 sampler channel (fixes bug #36)
1374
1375 Version 0.3.3 (15 July 2005)
1376
1377 * packaging changes:
1378 - fixed compilation with gcc 4.0
1379
1380 * Gigasampler format engine:
1381 - LFO preprocessing was performed even though the respective LFO was
1382 disabled by the instrument patch (minor efficiency fix)
1383 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1384 for volume ramp downs in the same fragment (needed for current voice
1385 stealing implementation) then simply inform the user with a warning
1386 about possible click sounds and reduce the volume ramp down
1387 appropriately instead of cancelling the audio device connection
1388
1389 Version 0.3.2 (24 June 2005)
1390
1391 * packaging changes:
1392 - updated autotools build files to compile on OS X
1393 (conditional compilation of CoreMIDI and MidiShare drivers)
1394 - hand-crafted assembly optimization code can be disabled with
1395 './configure --disable-asm' (definitely not recommended)
1396 - fixed 'make dist' rule to include all necessary files
1397 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1398 (due to 'dist-bzip2' automake option)
1399
1400 * Gigasampler format engine:
1401 - support for the gig parameters for "release velocity response" curves
1402 - fine tuning of the EGADSR envelope
1403 - volume of release triggered samples now depends on note-on velocity,
1404 note length and gig parameter "release trigger decay" instead of
1405 note-off velocity.
1406 - revised voice stealing
1407 (fixes crash and endless loop caused by voice stealing)
1408 - don't reset scale tuning on instrument or audio output device change
1409 - handle key group conflicts right at the beginning of each fragment
1410 instead of when the respective voice is actually launched
1411 (fixes undefined behavior if stolen voices belonged to a key group -
1412 this case was followed by a "killed voice survived" error message)
1413 - fixed minor issue with null/silence samples
1414 (those stole voices even though they don't need a voice at all which
1415 resulted in "voice stealing didn't work out" messages)
1416 - don't reset volume, pan, pitch and MIDI controller values on
1417 instrument or audio output device change
1418
1419 * LSCP server:
1420 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1421 - fixed LSCP event "CHANNEL_INFO" notification
1422 (e.g. did not notify on volume changes or MIDI program change events)
1423
1424 * linuxsampler application:
1425 - added command line parameters --lscp-addr and --lscp-port to override
1426 default IP address and port of LSCP server
1427
1428 Version 0.3.1 (24 May 2005)
1429
1430 * initial release
