* Gig format extension: If requested by instrument then don't play
  release trigger sample on note-off events.
* Bumped version (2.1.0.svn3).

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

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

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

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

294 - Mac OS X: fixed building outside source directory
295 - made sure all source files for hostplugins are included when
296 doing "make dist"
297 - removed empty directories left from the cvs to svn migration
298 - fixed compilation with gcc 4.6.1
299 - another "make dist" fix, for the LV2 plugin

320 - Mac OS X: added temporary hack allowing to spawn gigedit as callback
321 on the process's main thread
322 - fixed build error on newer MinGW
323 - support building with older jack versions
324 - support building with spaces in vst sdk path
325 - enabled automake 'subdir-objects' option and moved external

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

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

856 (fixes bug #70, patch by Ronald Baljeu)
857 - fixed endless loop which occured when loading an instrument editor
858 plugin DLL on Windows systems failed
859 - fixed memory leaks that occurred when liblinuxsampler was unloaded
860 - optimized the SynchronizedConfig class so it doesn't wait
861 unnecessarily long after an update
862 - added support for notifying instrument editors on note-on / note-off
863 events (e.g. to highlight the pressed keys on the virtual keyboard
864 of gigedit)
865 - added support for triggering notes by instrument editors (see above)
866 - be verbose on DLL load errors (on Linux)
867 - fixed di-harmonic triangle LFO implementation (this LFO implementation
868 is only used by very few systems, most pick the int math
869 implementation, which is usually faster)
870 - fixes for audio drivers with varying buffer sizes
871 - experimental support for running LinuxSampler as a DSSI, LV2 and
872 VST plugin
873 - notification events for stream/voice count statistics are now sent
874 only when there are actual changes
875 - added memory ordering constraints to improve stability on
876 multi-core and multi-cpu systems
877 - maximum voices and disk streams can now be altered at runtime
878 - fixed CPU feature detection on x86_64 (maybe fixes #108)
879 - automatic stacktrace mechanism is now turned off by default and can
880 be switched on by command line option "--stacktrace" (the automatic
881 stacktrace mechanism seems to be broken on most systems at the moment)
882 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
883 a pointer to the launched InstrumentEditor object
884 - added optional 3rd party user data parameter for following
885 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
886 InstrumentEditor::Launch(),
887 InstrumentManager::LaunchInstrumentEditor()
888 - theoretical fix: made SynchronizedConfig follow C++0x memory
889 model more strictly
890 - fixes for using large audio device buffers
891 - Windows: add the installation directory to the DLL search path
892 when loading an editor plugin (solves problems with VST and
893 gigedit on systems with other GTK versions installed)
894 - updated linuxsampler man page
895
896 * audio driver:
897 - removed the nonsense audio channel constraint (which was hard coded to
898 max. 100 audio channels) for most audio drivers
899 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
900 opposed to the LSCP specs
901 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
902 reflected the wrong value
903 - fixed a memory management bug in ASIO driver
904 - Makefile fix: JACK_CFLAGS wasn't used
905 - JACK: use jack_client_open instead of the deprecated
906 jack_client_new
907 - added (experimental) CoreAudio driver
908 - applied old fixes to the ASIO driver that were included in the
909 previous binary release but accidentally never committed to CVS
910 (fixes #117)
911 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
912 win64)
913 - VST: added support for sample rate and buffer size changes
914 - VST: close editor (Fantasia) when the VST is removed
915 - VST: avoid opening Fantasia more than once for each VST instance
916 - VST: export main function as "main" on Linux too (fix for
917 energyXT)
918 - VST: changed number of output channels from one stereo to 16
919 stereo
920 - added channel routing, fxsends and midi maps to the settings
921 stored in the plugin state
922 - performance optimization of AudioChannel::MixTo() and
923 AudioChannel::CopyTo() methods using GCC vector exensions
924 (if available)
925 - ASIO fixes: avoid initializing the device twice, avoid throwing
926 exception when getting parameters from a disconnected device
927
928 * MIDI driver:
929 - added JACK MIDI driver
930 - dispatch bank select as ordinary CC as well, the user might seriously
931 want to (mis)use it for some purpose ("fixed" in all current MIDI
932 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
933 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
934 CoreMidi or AU
935 - fixed mingw-w64 compilation error in MME driver
936 - made program change handling in MIDI thread real-time safe by
937 moving the logic to a non-RT thread
938 - fixed minor memory leak in ALSA driver
939
940 * instruments database:
941 - avoid time consuming samples scanning when adding instruments
942 to the instruments database
943 - added support for handling lost files in the instruments database
944 - Implemented option for adding instruments in separate directories
945 in the instruments database
946 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
947 - work-around for missing fnmatch function on Windows to make
948 instrument database compilable
949 - added instrument database support on Windows
950 works with both standalone mode and VST plugin.
951 the instruments DB file is located in
952 %USERPROFILE%\.linuxsampler\instruments.db which allows different
953 databases for each windows user
954 if no DB is present it automatically creates the .linuxsampler subdir
955 and then creates an empty DB
956 - fixed recursive import, which was broken on Windows
957
958 * Gigasampler format engine:
959 - fixed a memory leak that could happen when a channel was deleted
960 while notes were playing
961 - made it possible to load an instrument even if the audio thread
962 isn't running
963 - added partial support for the "Controller Triggered" MIDI rule,
964 enough for piano gigs with pedal noise samples
965 - minor fix: only mark FX sends as being modified if really the
966 respective FX send MIDI controller was used
967 - added support for GM global device volume SysEx message
968 (can be selected at compile time to either apply globally to the
969 whole sampler [default] or only to the sampler channels that are
970 connected to the respective MIDI input port the SysEx message arrived
971 on)
972 - bugfix: notes triggered at position 0 in the audio buffer were
973 sometimes wrongly killed in the same buffer, causing no sound to
974 be played
975 - added support for chromatic / drumkit mode Roland GS Sysex message
976 which is usally used to switch a part between chromatic sounds and
977 drumkit sounds (as opposed to their common default setting of MIDI
978 part 10 being a drumkit part and all other ones chromatic parts), in
979 LS however one can switch between the first 16 MIDI instrument maps
980 defined for the sampler
981 - made it possible to create multiple sample channels even if the
982 audio thread isn't running
983 - fixed crash when removing channel with active voices (#116)
984 - bugfix: on sample reference changes (instrument editor), only
985 un-cache the respective sample if it's really not used by any
986 sampler engine anymore
987 - re-cache samples in case they were changed by an instrument editor,
988 e.g. when a sample was added while playing (#82)
989 - fixed hanging notes which occured when note-off event had the exact
990 same time stamp as the voice's note-on event and occured both in the
991 same audio fragment cycle (fixes bug #112)
992 - added support for the "fine tune" and "pitch bend range"
993 instrument-level gig parameters
994 - fixed minor artifacts in pitch bend handling
995 - added support for GS Reset SysEx message
996 - allow gig files to use unlimited downward pitch shifting
997 - added a limit check for upward pitch shifting
998 - bugfix: sometimes, when playing a note twice fast, the second
999 note was silent
1000 - fixed crash happening when a pitch bend event arrived at the
1001 same time a new instrument was loading
1002
1003 * LSCP server:
1004 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
1005 react on MIDI data arriving on certain sampler channels (so far only
1006 Note-On and Note-Off events are sent via this LSCP event)
1007 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1008 react on MIDI data arriving on certain MIDI input devices (so far only
1009 Note-On and Note-Off events are sent via this LSCP event)
1010 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
1011 SET DB_INSTRUMENT FILE_PATH
1012 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
1013 frontends to send MIDI messages to specific sampler channel
1014 - added two additional fields to GET FILE INSTRUMENT INFO command -
1015 KEY_BINDINGS and KEYSWITCH_BINDINGS
1016 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1017 was incorrect
1018 - Optimized the retrieval of the MIDI instrument mappings
1019 - added new LSCP command "SET VOICES" to globally alter the maximum
1020 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1021 be triggered respectively
1022 - added new LSCP command "SET STREAMS" to globally alter the maximum
1023 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1024 which will be triggered respectively
1025 - bugfix: retry if "select" returns EINTR (this fixes a crash when
1026 a gigedit file dialog is opened)
1027 - close all connections when LSCPServer is deleted
1028 - hard close of all sockets on exit
1029 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
1030 driver
1031
1032 * Bug fixes:
1033 - fixed a crash which occurs when removing a sampler channel waiting
1034 to start instrument loading after another channel
1035 - fixed a crash which occurs when removing a sampler channel with
1036 instrument loading in progress (bug #113)
1037 - fixed termination caused by uncaught exception when adding MIDI
1038 instrument with PERSISTENT load mode
1039 - fixed possible iterator invalidations when resetting the sampler
1040 - fixed memory leaks when issuing the following LSCP commands:
1041 GET AUDIO_OUTPUT_DRIVER INFO
1042 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
1043 GET MIDI_INPUT_DRIVER INFO
1044 GET MIDI_INPUT_DRIVER_PARAMETER INFO
1045 - fixed possible compilation error when sqlite is not present
1046 - fixed orphaned pointers when setting maximum voices limit (bug #118)
1047 - fixed crash when changing the audio output device of a sampler
1048 channel with loaded instrument and start playing notes
1049 - fixed endless loop in Engine::SuspendAll() (bug #120)
1050 - fixed a low-level atomic load function that was broken on 64-bit
1051 PowerPC, which probably could cause crashes on that platform
1052 - fixed a memory management error which could cause a crash when a
1053 plugin was unloaded
1054 - bugfix: two private structs had the same name, which could cause
1055 problems if the linker chose the wrong constructor
1056 - fixed low-level ConditionServer usage bug that caused lockups on
1057 Windows
1058
1059
1060 Version 0.5.1 (6 December 2007)
1061
1062 * packaging changes:
1063 - added autoconf checks for pthread library
1064 - added autoconf check for pthread bug found on certain NPTL-enabled
1065 glibc versions (see Gentoo bug report #194076)
1066 - added autoconf checks for MS Windows
1067
1068 * general changes:
1069 - bugfix: the thread used by an editor plugin didn't die when the
1070 editor closed
1071 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1072 out all the space. operator--() did not apply size_mask after
1073 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1074 order to avoid problems with the _NonVolatileReader functions.
1075 - bugfix: Stream.h: added a missing divide by BytesPerSample in
1076 GetWriteSpace(). Since this function is currently only used in
1077 the stream's qsort() compare function, it didn't trigger any
1078 bugs.
1079 - Resampler.h, Synthesizer.h: cubic interpolation now works in
1080 24bit mode too. Faster method to read 24bit words on little
1081 endian machines (x86): replaced 3 byte reads + shifts with a 1
1082 unaligned 32bit read and shift
1083 - experimental support for MS Windows (MIDI input via MME, AUDIO
1084 output via ASIO)
1085 - made handling of SIGINT signal (Ctrl-C) a bit more robust
1086 - support for monitoring the total number of active disk streams
1087 (new LSCP commands: GET TOTAL_STREAM_COUNT,
1088 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1089
1090 * AUDIO driver:
1091 - added Windows ASIO low latency audio driver
1092
1093 * MIDI driver:
1094 - added MME Windows MIDI driver
1095
1096 * LSCP server:
1097 - added support for Windows style path / filenames, however with
1098 forward slash path separators instead of backslash
1099 (i.e. "C:/foo/bar.gig")
1100 - allow naughty liblscp to send non-string device parameters within
1101 apostrophes as well
1102 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1103 "LIST FILE INSTRUMENTS <file>" and
1104 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1105 about an arbitrary instrument file on the system where the sampler is
1106 running on
1107
1108 Version 0.5.0 (15 October 2007)
1109
1110 * packaging changes:
1111 - config.h is not going to be installed along with liblinuxsampler's
1112 API header files anymore
1113 - only the API relevant header (and source) files will be exported to
1114 the Doxygen API documentation (explicitly listed in Doxyfile.in)
1115 - added completely new XCode project files for Mac OSX which is now
1116 capable to execute our autoconf environment, thus no need anymore
1117 to maintain the compile time configuration file (osx/version.h) for
1118 OSX manually (patch by Toshi Nagata)
1119 - fixed buggy boolean --enable-foo / --disable-foo configure script
1120 parameters
1121 - global.h now only covers global definitions that are needed for the
1122 C++ API header files, all implementation internal global definitions
1123 are now in global_private.h
1124 - atomic.h is not exposed to the C++ API anymore
1125 - no need to include config.h anymore for using LS's API header files
1126 - fixed warnings in API doc generation
1127
1128 * general changes:
1129 - replaced the old, confusing MIDI program change mechanism by a
1130 flexible MIDI instrument mapper which allows to map arbitrary
1131 (MIDI bank, MIDI program) pairs with arbitrary
1132 (engine type, instrument file, file index) triplets which will be
1133 loaded on the respective channel when such MIDI program change
1134 messages arrive, beside that, each entry allows to define a life-time
1135 strategy for the instrument, so the user can define whether the
1136 instrument should i.e. be permanently loaded (to be able to switch
1137 quickly among sounds) or i.e. loaded just on demand when the
1138 respective program change arrives (to safe RAM space), as well as a
1139 global volume factor for each entry, so the user can adjust the volume
1140 dynamic of his mapped instrument collection without having to modify
1141 the instrument files, also one can manage arbitrary amount of such
1142 MIDI instrument maps and assign each sampler channel individually
1143 a certain map, so that i.e. separation of normal instruments and
1144 drumkits is possible
1145 - new notification events for tracking changes to audio/MIDI devices,
1146 MIDI instrument maps, MIDI instruments, FX sends, global volume.
1147 - sampler was limited to load max. 200 instruments in the background
1148 due to a constant size RingBuffer FIFO which is now replaced by a
1149 dynamic (unlimited) size std::list FIFO
1150 - added FX sends, these allow to route audio signals to arbitrary audio
1151 output channels for being processed by external effect processors
1152 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1153 controllers
1154 - global (sampler wide) volume can now be controlled at runtime
1155 - Implemented new, improved notification system
1156 - fixed compilation errors regarding OSX
1157 (patch by Toshi Nagata)
1158 - implemented instruments database
1159 - added support for escape sequences to the instruments database
1160 - added highly experimental support for on-the-fly instrument editing
1161 within the sampler's process (by using instrument editor plugins),
1162 you'll notice the new "Registered instrument editors:" message on
1163 startup, added a new LSCP command:
1164 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1165 to spawn a matching instrument editor for the instrument on the
1166 given sampler channel, the plugin path can be overridden at compile
1167 time with ./configure --enable-plugin-dir=/some/dir
1168 - added experimental code for synchronizing instrument editors hosted
1169 in the sampler's process to safely edit instruments while playing
1170 without a crash (hopefully) by either suspending single regions
1171 wherever possible or if unavoidable whole engine(s)
1172 - fixed several issues in fundamental "Thread" class: set scheduling
1173 policy and priority on thread level, set a minimum stack size for
1174 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1175 threads simply inherited properties of starting thread instead of
1176 setting their own policy and priority
1177 - minor fix in our automatic stack trace mechanism on crashes, the
1178 main process did not wait for the stack trace process to finish
1179 its output
1180 - fixed some minor memory leaks
1181 - reenabled assembly features support, at the moment only for
1182 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1183 - minor assembly fix in x86 features detection (don't use the PIC
1184 register, to avoid relocations in the text segment at runtime)
1185 - POSIX callback functions of Thread.h are hidden
1186
1187 * MIDI driver:
1188 - dispatch bank select (MSB and LSB) messages
1189
1190 * audio driver:
1191 - the ALSA audio output driver parameters now reflect the correct
1192 parameter value ranges for the respective selected sound card
1193 (patch by Till Wimmer, a bit fixed and extended)
1194
1195 * Gigasampler format engine:
1196 - if a filter is used and EG2 finishes before EG1, let the voice
1197 die when EG2 has finished (this fixes a problem with clicks and
1198 voice starvation for some gigs)
1199 - playback is no longer disabled during instrument loading
1200 - all notes playing on a channel that changes its instrument keep
1201 playing with the old instrument until they get a note off
1202 command
1203 - EG fix: a release value of zero could cause noises or crash
1204 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1205 - EG fine tuning: when attack is zero the EG starts at a level
1206 above max sustain level, which means that there is a decay phase
1207 even if sustain is 100%
1208 - more EG fixes: the level could sometimes go below zero and cause
1209 noises or crashes
1210 - minor fix of EGDecay (patch by Toshi Nagata)
1211 - fixed compiler error when --enable-override-filter-type was
1212 supplied to the configure script (fixes #46)
1213 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1214 instead of a fix value
1215 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1216 127 (solo mode) only kill voices if the respective mode really
1217 changed
1218
1219 * LSCP server:
1220 - fixed compile time error for old Bison versions
1221 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1222 - parser now supports extended ASCII character set
1223 (up to ASCII code 255, i.e. includes now umlauts and accents)
1224 - filename arguments in LSCP commands now allow to use escape
1225 sequences, that is directly literal as one of: \', \", \\, \n, \r,
1226 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1227 code value like \xf2) (fixes bug #24)
1228 - the following LSCP commands now also support escape sequences for at
1229 least one of their text-based parameters (i.e. name, description):
1230 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1231 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1232 "SET DB_INSTRUMENT_DIRECTORY NAME",
1233 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1234 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1235 "FIND DB_INSTRUMENT_DIRECTORIES"
1236 - returns verbose syntax errors (line and column where syntax error
1237 occured, the unexpected character and the actually expected, possible
1238 character(s), the latter only if less than 5 possibilities)
1239 - made sure that LSCP syntax is not affected by gigedit locale
1240 settings
1241 - bugfix regarding strings parameter lists: all comma separated lists
1242 of strings were treated as being one string containing commas
1243 (fixes #57)
1244
1245 * Bug fixes:
1246 - fixed crash occurring on certain LSCP scripts (Bug 39)
1247 - another thread safety fix for lscp "load engine" and "set
1248 channel audio output device"
1249 - fixed a crash which occurs when reassigning the same engine
1250 on a sampler channel with connected MIDI device
1251 - fixed a crash which occurs when changing the number of ports of a MIDI
1252 device connected to a sampler channel to number less then or equal
1253 to the index of the port to which the sampler channel is connected.
1254 - The previous bindings were not been disconnected when altering
1255 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1256 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1257 - The active stream/voice count statistic was incorrect.
1258 - notification events were not been sent for some sampler
1259 channel changes
1260 - added default min and max values to restrict the number of allowed
1261 audio output channels and MIDI input ports
1262 - the connection to the PCM interface is now closed when destroying
1263 an audio output device
1264 - files with slash in their path or filename could not be loaded
1265
1266 * test cases:
1267 - updated and fixed (haven't been touched in a while)
1268
1269 Version 0.4.0 (24 November 2006)
1270
1271 * packaging changes:
1272 - changed deprecated copyright attribute to license; added ldconfig
1273 to post-(un)install steps; added devel package for liblinuxsampler;
1274 to linuxsampler.spec (RPM)
1275 - install necessary development header files for allowing 3rd party
1276 applications to link against liblinuxsampler
1277 - liblinuxsampler's API documentation can be generated with 'make docs'
1278 (Doxygen required)
1279 - added benchmark to automatically detect the best triangle LFO
1280 implementation (currently either an integer math solution or a
1281 di-harmonic approximation), automatic detection can be overriden
1282 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1283 configure script argument though (mandatory for cross-compilation)
1284 - do not automatically pick optimized gcc flags if the user already
1285 provided some on his own (as CXXFLAGS)
1286 - added compile time option to disable processing of All-Notes-Off MIDI
1287 messages
1288 - added compile time options to allow disabling the various audio and
1289 MIDI drivers
1290 - fixed automatic GCC CPU switch detection on PPC
1291 (patch by Ebrahim Mayat)
1292
1293 * Gigasampler format engine:
1294 - extensive synthesis optimization
1295 (reimplementation of EGs and LFO(s), removed synthesis parameter
1296 prerendering and the synthesis parameter matrix in general, splitting
1297 each audio fragment into subfragments now where each subfragment uses
1298 constant pitch and filter coefficients. The volume coefficient is
1299 linearly interpolated inside a subfragment, unless
1300 --disable-interpolate-volume is set.)
1301 - fine tuning of the EG modulation parameters
1302 - improved filter cutoff calculation by adding support for the
1303 following gig parameters: Cutoff freq (used when no cutoff
1304 controller is defined), Control invert, Minimum cutoff, Velocity
1305 curve and Velocity range. The keyboard tracking now scales
1306 cutoff frequency instead of resonance.
1307 - added support for gig parameter Resonance.
1308 - fixed bug in sysex handling (patch by Juan Linietsky)
1309 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1310 which can be overridden with --enable-global-attenuation
1311 - EG fixes: made the length of "attack hold" stage more
1312 accurate. Release stage can now start before attack stage
1313 ends. Cancel release didn't work when sustain was zero. Attack
1314 time now has a minimal value to prevent clicks.
1315 - fixed pitch changes larger than one octave
1316 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1317 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1318 all modes can be altered via standard GM messages, that is CC5 for
1319 altering portamento time, CC65 for enabling / disabling portamento
1320 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1321 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1322 parameter) and crossfade
1323 - added support for the "attenuation controller threshold" gig
1324 parameter
1325 - added smoothing of volume changes caused by control change
1326 messages
1327 - sample loop parameters are now taken from the DimensionRegion
1328 instead of the wave chunk
1329 - fixed keyswitching for v3 gigs with a number of keyswitch splits
1330 not equal to a power of two
1331 - reimplementation of the filter algorithm. The new filter is more
1332 accurate and supports all gig filter types, including bandreject
1333 and lowpass turbo.
1334 - real support for 24 bit samples - samples are not truncated to
1335 16 bits anymore
1336 - support for aftertouch (channel pressure, not polyphonic
1337 aftertouch)
1338 - LFO1 behaviour fixed (dampening from max volume instead of
1339 amplifying from 0)
1340
1341 * LSCP server:
1342 - fixed application exit on broken pipe error (fixes bug #20)
1343 - fixed the notification messages delay due to lack of
1344 network activity (fixes bug #26)
1345 - fixed parser bug which occured on space(s) within device parameters
1346 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1347
1348 * audio driver:
1349 - added aRts audio output driver (by no means RT safe)
1350
1351 * MIDI driver:
1352 - fixed legacy sysex code which caused dispatching of MIDI SysEx
1353 messages several times instead of once
1354 - API extension for MIDI drivers which already supply exact time stamps
1355 for events (i.e. for offline rendering based MIDI drivers)
1356 - added checks for bad MIDI data
1357
1358 * linuxsampler application:
1359 - show available sampler engine types on startup
1360
1361 * general changes:
1362 - support for muting sampler channels and solo mode of the same, two new
1363 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1364 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1365 introduced for this, the behavior is the same like on a mixer console
1366 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1367 --enable-process-muted-channels which can be used to enable the
1368 processing of muted channels.
1369 - support for sostenuto pedal
1370 - support for monitoring the total number of active voices
1371 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1372 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1373 - fixed some memory management errors
1374 - fixed some concurrency problems that could lead to crashes when
1375 LSCP commands were executed
1376 - fixed crash when instrument loading failed previously on the same
1377 sampler channel (fixes bug #36)
1378
1379 Version 0.3.3 (15 July 2005)
1380
1381 * packaging changes:
1382 - fixed compilation with gcc 4.0
1383
1384 * Gigasampler format engine:
1385 - LFO preprocessing was performed even though the respective LFO was
1386 disabled by the instrument patch (minor efficiency fix)
1387 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1388 for volume ramp downs in the same fragment (needed for current voice
1389 stealing implementation) then simply inform the user with a warning
1390 about possible click sounds and reduce the volume ramp down
1391 appropriately instead of cancelling the audio device connection
1392
1393 Version 0.3.2 (24 June 2005)
1394
1395 * packaging changes:
1396 - updated autotools build files to compile on OS X
1397 (conditional compilation of CoreMIDI and MidiShare drivers)
1398 - hand-crafted assembly optimization code can be disabled with
1399 './configure --disable-asm' (definitely not recommended)
1400 - fixed 'make dist' rule to include all necessary files
1401 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1402 (due to 'dist-bzip2' automake option)
1403
1404 * Gigasampler format engine:
1405 - support for the gig parameters for "release velocity response" curves
1406 - fine tuning of the EGADSR envelope
1407 - volume of release triggered samples now depends on note-on velocity,
1408 note length and gig parameter "release trigger decay" instead of
1409 note-off velocity.
1410 - revised voice stealing
1411 (fixes crash and endless loop caused by voice stealing)
1412 - don't reset scale tuning on instrument or audio output device change
1413 - handle key group conflicts right at the beginning of each fragment
1414 instead of when the respective voice is actually launched
1415 (fixes undefined behavior if stolen voices belonged to a key group -
1416 this case was followed by a "killed voice survived" error message)
1417 - fixed minor issue with null/silence samples
1418 (those stole voices even though they don't need a voice at all which
1419 resulted in "voice stealing didn't work out" messages)
1420 - don't reset volume, pan, pitch and MIDI controller values on
1421 instrument or audio output device change
1422
1423 * LSCP server:
1424 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1425 - fixed LSCP event "CHANNEL_INFO" notification
1426 (e.g. did not notify on volume changes or MIDI program change events)
1427
1428 * linuxsampler application:
1429 - added command line parameters --lscp-addr and --lscp-port to override
1430 default IP address and port of LSCP server
1431
1432 Version 0.3.1 (24 May 2005)
1433
1434 * initial release
