* SFZ: Fixed potential crash when a sample is shared by more than one
  region (fixes bug #308, patch by Jacek Roszkowski).
* SFZ: Added OVERRIDEs to avoid bug #307 in future.
* Bumped version (2.1.0.svn6).

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 - Fixed compiler warnings.
12 - Fixed compilation error when cross-compiling to Mac.
13
14 * Gigasampler/GigaStudio format engine:
15 - Format extension: If requested by instrument then don't play release
16 trigger sample on note-off events.
17
18 * SFZ format engine:
19 - Fixed memory leak when releasing samples
20 (fixes bug #307, patch by Jacek Roszkowski)
21 - Fixed potential crash when a sample is shared by more than one region
22 (fixes bug #308, patch by Jacek Roszkowski).
23
24 Version 2.1.0 (25 Nov 2017)
25
26 * SFZ format engine:
27 - added support for <global>, <master> and #define (patch by Alby M)
28 - Removed code duplication in SFZ file loading code.
29 - Added support for sfz extension opcode 'script' which may be used to
30 load real-time instrument script file (NKSP script language).
31 - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
32 - Fixed unintended volume fade-in of voices under certain conditions.
33 - sfz parser: allow missing space between header and opcode
34
35 * Gigasampler/GigaStudio format engine:
36 - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
37 cutoff settings.
38 - Got rid of resembling an ancient GSt misbehavior which did not pitch at
39 all if an up-pitch of more than 40 semi tones was requested (I don't
40 think there is any stock gig sound that requires this behavior to
41 resemble its original sound).
42 - Added support for controlling whether the individual EGADSR stages may
43 be aborted (as LinuxSampler extension to the original GigaStudio 4
44 format).
45
46 * general changes:
47 - fixed printf type errors (mostly in debug messages)
48 - use unique_ptr instead of auto_ptr when building with C++11
49 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
50 allowing to sort data efficiently in real-time safe manner.
51 - RTList class: added methods for moving/inserting elements to arbitrary
52 position within a list.
53 - RTList class: added method fromPtr() for creating an Iterator object from
54 a raw element pointer.
55 - Attempt to partly fix resetting engine channels vs. resetting engine, an
56 overall cleanup of the Reset*(), ConnectAudioDevice(),
57 DisconnectAudioDevice() API methods would still be desirable though,
58 because the current situation is still inconsistent and error prone.
59 - Active voices are now internally grouped to "Note" objects, instead of
60 being directly assigned to a keyboard key. This allows more fine graded
61 processing of voices, which is i.e. required for certain instrument
62 script features.
63 - Fix: Release trigger voices were not spawned on sustain pedal up
64 (CC #64) events.
65 - Fix: Release trigger voices can now also distinguish correctly between
66 note-off and sustain pedal up events.
67 - All engines: Increased ramp speed of volume smoother and pan smoother
68 (while slow rate of crossfade smoother is preserved) to allow quick
69 volume and pan changes by instrument scripts for instance.
70 - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
71 properly and thus were ignored for certain uses.
72 - Added new C++ API method
73 VirtualMidiDevice::SendChannelPressureToSampler().
74 - windows, 32-bit: fixed potential crashes by making sure the stack in
75 sub threads is 16-byte aligned
76 - fixed numerous compiler warnings
77 - Fixed invalid (note-on) event ID being assigned to new Note objects.
78 - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
79 fixes potential undefined behavior.
80 - Fixed Note object leak when triggering notes on keys which did not
81 have a valid sample mapped (fixes bug #252).
82 - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
83 - linuxsampler binary fix: option --create-instruments-db ignored
84 subsequent optional argument due to glibc's implementation oddity
85 which expects a "=" sign, but no space between them.
86
87 * packaging changes:
88 - removed unnecessary dependency to libuuid
89 (originated by libgig's usage of it)
90 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
91 auto detect whether it (sh/c)ould output its messages in color.
92 - Debian: Fixed packaging error about invalid "Source-Version"
93 substitution variable.
94 - Debian: Raised Debian compatibility level to Debian 9 "Stretch".
95 - Debian: Added build dependency to libsqlite3-dev for building
96 linuxsampler with instruments DB support.
97
98 * Real-time instrument scripts:
99 - Implemented scheduler for delayed MIDI events and for suspended scripts.
100 - Built-in script function "wait()": implemented support for function's
101 "duration-us" argument, thus scripts using this function are now
102 correctly resumed after the requested amount of microseconds.
103 - Built-in script function "play_note()": implemented support for
104 function's "duration-us" argument, thus notes triggered with this
105 argument are now correctly released after the requested amount of
106 microseconds.
107 - Fix: script events were not cleared when engine channel was reset,
108 potentially causing undefined behavior.
109 - Fixed crash which happened when trying to reference an undeclared
110 variable.
111 - Built-in script function "play_note()": Added support for passing
112 special value -1 for "duration-us" argument, which will cause the
113 triggered note to be released once the original note was released.
114 - Instrument script classes now exported with the liblinuxsampler C++ API.
115 - Added new API method ScriptVM::syntaxHighlighting() which provides
116 a convenient syntax highlighting backend for external instrument
117 script editor applications.
118 - Added new C++ API class "ScriptVMFactory".
119 - Extended parser issues to provide not only first line and first
120 column, but also last line and last column of issue (thus marking
121 the precise span of the issue within the source code).
122 - Reload script automatically after being modified by an instrument
123 editor.
124 - NKSP language grammar correction: allow empty event handler bodies
125 like "on note end on".
126 - Implemented built-in script function "change_vol()".
127 - Implemented built-in script function "change_tune()".
128 - Implemented built-in script function "change_pan()".
129 - Implemented built-in script function "change_cutoff()".
130 - Implemented built-in script function "change_reso()".
131 - Implemented built-in script function "event_status()".
132 - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
133 "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
134 "event_status()" function.
135 - NKSP language: Added support for bitwise operators ".or.", ".and."
136 and ".not.".
137 - NKSP language scanner: Fixed IDs matching to require at least one
138 character (i.e. when matching function names or variable names).
139 - NKSP language scanner: disabled unusued rules.
140 - Fixed behavior of play_note() and note_off() functions which must
141 be distinguished engine internally from "real" MIDI note on/off
142 events in order to avoid misbehaviors like hanging notes.
143 - Implemented built-in script variable "$KSP_TIMER".
144 - Implemented built-in script variable "$NKSP_REAL_TIMER".
145 - Implemented built-in script variable "$NKSP_PERF_TIMER".
146 - Implemented built-in script variable "$ENGINE_UPTIME".
147 - Implemented built-in script function "inc()".
148 - Implemented built-in script function "dec()".
149 - NKSP language fix: division expressions were evaluated too often.
150 - NKSP language fix: string concatenation operator was right
151 associative instead of left (to right).
152 - NKSP language correction: allow empty statements in entire language
153 (i.e. "if end if").
154 - Implemented built-in script function "stop_wait()".
155 - Implemented built-in script variable "$NI_CALLBACK_ID".
156 - Implemented built-in script variable "$NI_CALLBACK_TYPE".
157 - Implemented built-in script variable "$NKSP_IGNORE_WAIT".
158 - Added support for read-only built-in variables (respectively
159 handled by the script parser).
160 - Added built-in script constant "$NI_CB_TYPE_INIT".
161 - Added built-in script constant "$NI_CB_TYPE_NOTE".
162 - Added built-in script constant "$NI_CB_TYPE_RELEASE".
163 - Added built-in script constant "$NI_CB_TYPE_CONTROLLER".

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

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

288 - Fixed memory access bug of general DB access code which lead to
289 undefined behavior.
290 - Cleanup of instruments DB file creation and opening code.
291 - The instrument DB path of linuxsampler's --create-instruments-db argument
292 is now optional, if it is missing, then a default location is used.
293 - Added support for scanning SFZ (.sfz) files.
294 - Added support for scanning Sound Font (.sf2) files.
295 - Fixed undefined DB transaction behavior.
296

328 - Mac OS X: added temporary hack allowing to spawn gigedit as callback
329 on the process's main thread
330 - fixed build error on newer MinGW
331 - support building with older jack versions
332 - support building with spaces in vst sdk path
333 - enabled automake 'subdir-objects' option and moved external

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

657 - added support for MIDI note on velocity filter
658 - CoreMIDI: fixed memory deallocation error
659 - Fixed variable underflow in VirtualMidiDevice, which caused graphical

829 crashes and noise on such transitions).
830 - ignore missing LADSPA paths without ignoring valid LADSPA paths
831 (fixes #208)
832 - Fixed bug in LSCP grammar definition which caused a statement like
833 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
834 practically irrelevant, however it caused problems with the new LSCP
835 shell's auto completion feature).
836 - Fixed MIDI program change messages being ignored if quickly executed
837 after each other (fixes #231).

855 directory above)
856 - configure script fix: removed unconditional use of SSE
857 - fixed building with sqlite installed in a non-standard directory
858 - when cross-compiling, don't try to create instruments.db
859 - fix for new mingw-w64 version, which has usleep
860
861 * general changes:
862 - bugfix: on some POSIX systems instrument editor plugins refused to
863 load as we used a non-portable Linux specific struct field
864 (fixes bug #70, patch by Ronald Baljeu)
865 - fixed endless loop which occured when loading an instrument editor
866 plugin DLL on Windows systems failed
867 - fixed memory leaks that occurred when liblinuxsampler was unloaded
868 - optimized the SynchronizedConfig class so it doesn't wait
869 unnecessarily long after an update
870 - added support for notifying instrument editors on note-on / note-off
871 events (e.g. to highlight the pressed keys on the virtual keyboard
872 of gigedit)
873 - added support for triggering notes by instrument editors (see above)
874 - be verbose on DLL load errors (on Linux)
875 - fixed di-harmonic triangle LFO implementation (this LFO implementation
876 is only used by very few systems, most pick the int math
877 implementation, which is usually faster)
878 - fixes for audio drivers with varying buffer sizes
879 - experimental support for running LinuxSampler as a DSSI, LV2 and
880 VST plugin
881 - notification events for stream/voice count statistics are now sent
882 only when there are actual changes
883 - added memory ordering constraints to improve stability on
884 multi-core and multi-cpu systems
885 - maximum voices and disk streams can now be altered at runtime
886 - fixed CPU feature detection on x86_64 (maybe fixes #108)
887 - automatic stacktrace mechanism is now turned off by default and can
888 be switched on by command line option "--stacktrace" (the automatic
889 stacktrace mechanism seems to be broken on most systems at the moment)
890 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
891 a pointer to the launched InstrumentEditor object
892 - added optional 3rd party user data parameter for following
893 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
894 InstrumentEditor::Launch(),
895 InstrumentManager::LaunchInstrumentEditor()
896 - theoretical fix: made SynchronizedConfig follow C++0x memory
897 model more strictly
898 - fixes for using large audio device buffers
899 - Windows: add the installation directory to the DLL search path
900 when loading an editor plugin (solves problems with VST and
901 gigedit on systems with other GTK versions installed)
902 - updated linuxsampler man page
903
904 * audio driver:
905 - removed the nonsense audio channel constraint (which was hard coded to
906 max. 100 audio channels) for most audio drivers
907 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
908 opposed to the LSCP specs
909 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
910 reflected the wrong value
911 - fixed a memory management bug in ASIO driver
912 - Makefile fix: JACK_CFLAGS wasn't used
913 - JACK: use jack_client_open instead of the deprecated
914 jack_client_new
915 - added (experimental) CoreAudio driver
916 - applied old fixes to the ASIO driver that were included in the
917 previous binary release but accidentally never committed to CVS
918 (fixes #117)
919 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
920 win64)
921 - VST: added support for sample rate and buffer size changes
922 - VST: close editor (Fantasia) when the VST is removed
923 - VST: avoid opening Fantasia more than once for each VST instance
924 - VST: export main function as "main" on Linux too (fix for
925 energyXT)
926 - VST: changed number of output channels from one stereo to 16
927 stereo
928 - added channel routing, fxsends and midi maps to the settings
929 stored in the plugin state
930 - performance optimization of AudioChannel::MixTo() and
931 AudioChannel::CopyTo() methods using GCC vector exensions
932 (if available)
933 - ASIO fixes: avoid initializing the device twice, avoid throwing
934 exception when getting parameters from a disconnected device
935
936 * MIDI driver:
937 - added JACK MIDI driver
938 - dispatch bank select as ordinary CC as well, the user might seriously
939 want to (mis)use it for some purpose ("fixed" in all current MIDI
940 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
941 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
942 CoreMidi or AU
943 - fixed mingw-w64 compilation error in MME driver
944 - made program change handling in MIDI thread real-time safe by
945 moving the logic to a non-RT thread
946 - fixed minor memory leak in ALSA driver
947
948 * instruments database:
949 - avoid time consuming samples scanning when adding instruments
950 to the instruments database
951 - added support for handling lost files in the instruments database
952 - Implemented option for adding instruments in separate directories
953 in the instruments database
954 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
955 - work-around for missing fnmatch function on Windows to make
956 instrument database compilable
957 - added instrument database support on Windows
958 works with both standalone mode and VST plugin.
959 the instruments DB file is located in
960 %USERPROFILE%\.linuxsampler\instruments.db which allows different
961 databases for each windows user
962 if no DB is present it automatically creates the .linuxsampler subdir
963 and then creates an empty DB
964 - fixed recursive import, which was broken on Windows
965
966 * Gigasampler format engine:
967 - fixed a memory leak that could happen when a channel was deleted
968 while notes were playing
969 - made it possible to load an instrument even if the audio thread
970 isn't running
971 - added partial support for the "Controller Triggered" MIDI rule,
972 enough for piano gigs with pedal noise samples
973 - minor fix: only mark FX sends as being modified if really the
974 respective FX send MIDI controller was used
975 - added support for GM global device volume SysEx message
976 (can be selected at compile time to either apply globally to the
977 whole sampler [default] or only to the sampler channels that are
978 connected to the respective MIDI input port the SysEx message arrived
979 on)
980 - bugfix: notes triggered at position 0 in the audio buffer were
981 sometimes wrongly killed in the same buffer, causing no sound to
982 be played
983 - added support for chromatic / drumkit mode Roland GS Sysex message
984 which is usally used to switch a part between chromatic sounds and
985 drumkit sounds (as opposed to their common default setting of MIDI
986 part 10 being a drumkit part and all other ones chromatic parts), in
987 LS however one can switch between the first 16 MIDI instrument maps
988 defined for the sampler
989 - made it possible to create multiple sample channels even if the
990 audio thread isn't running
991 - fixed crash when removing channel with active voices (#116)
992 - bugfix: on sample reference changes (instrument editor), only
993 un-cache the respective sample if it's really not used by any
994 sampler engine anymore
995 - re-cache samples in case they were changed by an instrument editor,
996 e.g. when a sample was added while playing (#82)
997 - fixed hanging notes which occured when note-off event had the exact
998 same time stamp as the voice's note-on event and occured both in the
999 same audio fragment cycle (fixes bug #112)
1000 - added support for the "fine tune" and "pitch bend range"
1001 instrument-level gig parameters
1002 - fixed minor artifacts in pitch bend handling
1003 - added support for GS Reset SysEx message
1004 - allow gig files to use unlimited downward pitch shifting
1005 - added a limit check for upward pitch shifting
1006 - bugfix: sometimes, when playing a note twice fast, the second
1007 note was silent
1008 - fixed crash happening when a pitch bend event arrived at the
1009 same time a new instrument was loading
1010
1011 * LSCP server:
1012 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
1013 react on MIDI data arriving on certain sampler channels (so far only
1014 Note-On and Note-Off events are sent via this LSCP event)
1015 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1016 react on MIDI data arriving on certain MIDI input devices (so far only
1017 Note-On and Note-Off events are sent via this LSCP event)
1018 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
1019 SET DB_INSTRUMENT FILE_PATH
1020 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
1021 frontends to send MIDI messages to specific sampler channel
1022 - added two additional fields to GET FILE INSTRUMENT INFO command -
1023 KEY_BINDINGS and KEYSWITCH_BINDINGS
1024 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1025 was incorrect
1026 - Optimized the retrieval of the MIDI instrument mappings
1027 - added new LSCP command "SET VOICES" to globally alter the maximum
1028 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1029 be triggered respectively
1030 - added new LSCP command "SET STREAMS" to globally alter the maximum
1031 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1032 which will be triggered respectively
1033 - bugfix: retry if "select" returns EINTR (this fixes a crash when
1034 a gigedit file dialog is opened)
1035 - close all connections when LSCPServer is deleted
1036 - hard close of all sockets on exit
1037 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
1038 driver
1039
1040 * Bug fixes:
1041 - fixed a crash which occurs when removing a sampler channel waiting
1042 to start instrument loading after another channel
1043 - fixed a crash which occurs when removing a sampler channel with
1044 instrument loading in progress (bug #113)
1045 - fixed termination caused by uncaught exception when adding MIDI
1046 instrument with PERSISTENT load mode
1047 - fixed possible iterator invalidations when resetting the sampler
1048 - fixed memory leaks when issuing the following LSCP commands:
1049 GET AUDIO_OUTPUT_DRIVER INFO
1050 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
1051 GET MIDI_INPUT_DRIVER INFO
1052 GET MIDI_INPUT_DRIVER_PARAMETER INFO
1053 - fixed possible compilation error when sqlite is not present
1054 - fixed orphaned pointers when setting maximum voices limit (bug #118)
1055 - fixed crash when changing the audio output device of a sampler
1056 channel with loaded instrument and start playing notes
1057 - fixed endless loop in Engine::SuspendAll() (bug #120)
1058 - fixed a low-level atomic load function that was broken on 64-bit
1059 PowerPC, which probably could cause crashes on that platform
1060 - fixed a memory management error which could cause a crash when a
1061 plugin was unloaded
1062 - bugfix: two private structs had the same name, which could cause
1063 problems if the linker chose the wrong constructor
1064 - fixed low-level ConditionServer usage bug that caused lockups on
1065 Windows
1066
1067
1068 Version 0.5.1 (6 December 2007)
1069
1070 * packaging changes:
1071 - added autoconf checks for pthread library
1072 - added autoconf check for pthread bug found on certain NPTL-enabled
1073 glibc versions (see Gentoo bug report #194076)
1074 - added autoconf checks for MS Windows
1075
1076 * general changes:
1077 - bugfix: the thread used by an editor plugin didn't die when the
1078 editor closed
1079 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1080 out all the space. operator--() did not apply size_mask after
1081 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1082 order to avoid problems with the _NonVolatileReader functions.
1083 - bugfix: Stream.h: added a missing divide by BytesPerSample in
1084 GetWriteSpace(). Since this function is currently only used in
1085 the stream's qsort() compare function, it didn't trigger any
1086 bugs.
1087 - Resampler.h, Synthesizer.h: cubic interpolation now works in
1088 24bit mode too. Faster method to read 24bit words on little
1089 endian machines (x86): replaced 3 byte reads + shifts with a 1
1090 unaligned 32bit read and shift
1091 - experimental support for MS Windows (MIDI input via MME, AUDIO
1092 output via ASIO)
1093 - made handling of SIGINT signal (Ctrl-C) a bit more robust
1094 - support for monitoring the total number of active disk streams
1095 (new LSCP commands: GET TOTAL_STREAM_COUNT,
1096 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1097
1098 * AUDIO driver:
1099 - added Windows ASIO low latency audio driver
1100
1101 * MIDI driver:
1102 - added MME Windows MIDI driver
1103
1104 * LSCP server:
1105 - added support for Windows style path / filenames, however with
1106 forward slash path separators instead of backslash
1107 (i.e. "C:/foo/bar.gig")
1108 - allow naughty liblscp to send non-string device parameters within
1109 apostrophes as well
1110 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1111 "LIST FILE INSTRUMENTS <file>" and
1112 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1113 about an arbitrary instrument file on the system where the sampler is
1114 running on
1115
1116 Version 0.5.0 (15 October 2007)
1117
1118 * packaging changes:
1119 - config.h is not going to be installed along with liblinuxsampler's
1120 API header files anymore
1121 - only the API relevant header (and source) files will be exported to
1122 the Doxygen API documentation (explicitly listed in Doxyfile.in)
1123 - added completely new XCode project files for Mac OSX which is now
1124 capable to execute our autoconf environment, thus no need anymore
1125 to maintain the compile time configuration file (osx/version.h) for
1126 OSX manually (patch by Toshi Nagata)
1127 - fixed buggy boolean --enable-foo / --disable-foo configure script
1128 parameters
1129 - global.h now only covers global definitions that are needed for the
1130 C++ API header files, all implementation internal global definitions
1131 are now in global_private.h
1132 - atomic.h is not exposed to the C++ API anymore
1133 - no need to include config.h anymore for using LS's API header files
1134 - fixed warnings in API doc generation
1135
1136 * general changes:
1137 - replaced the old, confusing MIDI program change mechanism by a
1138 flexible MIDI instrument mapper which allows to map arbitrary
1139 (MIDI bank, MIDI program) pairs with arbitrary
1140 (engine type, instrument file, file index) triplets which will be
1141 loaded on the respective channel when such MIDI program change
1142 messages arrive, beside that, each entry allows to define a life-time
1143 strategy for the instrument, so the user can define whether the
1144 instrument should i.e. be permanently loaded (to be able to switch
1145 quickly among sounds) or i.e. loaded just on demand when the
1146 respective program change arrives (to safe RAM space), as well as a
1147 global volume factor for each entry, so the user can adjust the volume
1148 dynamic of his mapped instrument collection without having to modify
1149 the instrument files, also one can manage arbitrary amount of such
1150 MIDI instrument maps and assign each sampler channel individually
1151 a certain map, so that i.e. separation of normal instruments and
1152 drumkits is possible
1153 - new notification events for tracking changes to audio/MIDI devices,
1154 MIDI instrument maps, MIDI instruments, FX sends, global volume.
1155 - sampler was limited to load max. 200 instruments in the background
1156 due to a constant size RingBuffer FIFO which is now replaced by a
1157 dynamic (unlimited) size std::list FIFO
1158 - added FX sends, these allow to route audio signals to arbitrary audio
1159 output channels for being processed by external effect processors
1160 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1161 controllers
1162 - global (sampler wide) volume can now be controlled at runtime
1163 - Implemented new, improved notification system
1164 - fixed compilation errors regarding OSX
1165 (patch by Toshi Nagata)
1166 - implemented instruments database
1167 - added support for escape sequences to the instruments database
1168 - added highly experimental support for on-the-fly instrument editing
1169 within the sampler's process (by using instrument editor plugins),
1170 you'll notice the new "Registered instrument editors:" message on
1171 startup, added a new LSCP command:
1172 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1173 to spawn a matching instrument editor for the instrument on the
1174 given sampler channel, the plugin path can be overridden at compile
1175 time with ./configure --enable-plugin-dir=/some/dir
1176 - added experimental code for synchronizing instrument editors hosted
1177 in the sampler's process to safely edit instruments while playing
1178 without a crash (hopefully) by either suspending single regions
1179 wherever possible or if unavoidable whole engine(s)
1180 - fixed several issues in fundamental "Thread" class: set scheduling
1181 policy and priority on thread level, set a minimum stack size for
1182 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1183 threads simply inherited properties of starting thread instead of
1184 setting their own policy and priority
1185 - minor fix in our automatic stack trace mechanism on crashes, the
1186 main process did not wait for the stack trace process to finish
1187 its output
1188 - fixed some minor memory leaks
1189 - reenabled assembly features support, at the moment only for
1190 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1191 - minor assembly fix in x86 features detection (don't use the PIC
1192 register, to avoid relocations in the text segment at runtime)
1193 - POSIX callback functions of Thread.h are hidden
1194
1195 * MIDI driver:
1196 - dispatch bank select (MSB and LSB) messages
1197
1198 * audio driver:
1199 - the ALSA audio output driver parameters now reflect the correct
1200 parameter value ranges for the respective selected sound card
1201 (patch by Till Wimmer, a bit fixed and extended)
1202
1203 * Gigasampler format engine:
1204 - if a filter is used and EG2 finishes before EG1, let the voice
1205 die when EG2 has finished (this fixes a problem with clicks and
1206 voice starvation for some gigs)
1207 - playback is no longer disabled during instrument loading
1208 - all notes playing on a channel that changes its instrument keep
1209 playing with the old instrument until they get a note off
1210 command
1211 - EG fix: a release value of zero could cause noises or crash
1212 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1213 - EG fine tuning: when attack is zero the EG starts at a level
1214 above max sustain level, which means that there is a decay phase
1215 even if sustain is 100%
1216 - more EG fixes: the level could sometimes go below zero and cause
1217 noises or crashes
1218 - minor fix of EGDecay (patch by Toshi Nagata)
1219 - fixed compiler error when --enable-override-filter-type was
1220 supplied to the configure script (fixes #46)
1221 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1222 instead of a fix value
1223 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1224 127 (solo mode) only kill voices if the respective mode really
1225 changed
1226
1227 * LSCP server:
1228 - fixed compile time error for old Bison versions
1229 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1230 - parser now supports extended ASCII character set
1231 (up to ASCII code 255, i.e. includes now umlauts and accents)
1232 - filename arguments in LSCP commands now allow to use escape
1233 sequences, that is directly literal as one of: \', \", \\, \n, \r,
1234 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1235 code value like \xf2) (fixes bug #24)
1236 - the following LSCP commands now also support escape sequences for at
1237 least one of their text-based parameters (i.e. name, description):
1238 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1239 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1240 "SET DB_INSTRUMENT_DIRECTORY NAME",
1241 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1242 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1243 "FIND DB_INSTRUMENT_DIRECTORIES"
1244 - returns verbose syntax errors (line and column where syntax error
1245 occured, the unexpected character and the actually expected, possible
1246 character(s), the latter only if less than 5 possibilities)
1247 - made sure that LSCP syntax is not affected by gigedit locale
1248 settings
1249 - bugfix regarding strings parameter lists: all comma separated lists
1250 of strings were treated as being one string containing commas
1251 (fixes #57)
1252
1253 * Bug fixes:
1254 - fixed crash occurring on certain LSCP scripts (Bug 39)
1255 - another thread safety fix for lscp "load engine" and "set
1256 channel audio output device"
1257 - fixed a crash which occurs when reassigning the same engine
1258 on a sampler channel with connected MIDI device
1259 - fixed a crash which occurs when changing the number of ports of a MIDI
1260 device connected to a sampler channel to number less then or equal
1261 to the index of the port to which the sampler channel is connected.
1262 - The previous bindings were not been disconnected when altering
1263 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1264 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1265 - The active stream/voice count statistic was incorrect.
1266 - notification events were not been sent for some sampler
1267 channel changes
1268 - added default min and max values to restrict the number of allowed
1269 audio output channels and MIDI input ports
1270 - the connection to the PCM interface is now closed when destroying
1271 an audio output device
1272 - files with slash in their path or filename could not be loaded
1273
1274 * test cases:
1275 - updated and fixed (haven't been touched in a while)
1276
1277 Version 0.4.0 (24 November 2006)
1278
1279 * packaging changes:
1280 - changed deprecated copyright attribute to license; added ldconfig
1281 to post-(un)install steps; added devel package for liblinuxsampler;
1282 to linuxsampler.spec (RPM)
1283 - install necessary development header files for allowing 3rd party
1284 applications to link against liblinuxsampler
1285 - liblinuxsampler's API documentation can be generated with 'make docs'
1286 (Doxygen required)
1287 - added benchmark to automatically detect the best triangle LFO
1288 implementation (currently either an integer math solution or a
1289 di-harmonic approximation), automatic detection can be overriden
1290 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1291 configure script argument though (mandatory for cross-compilation)
1292 - do not automatically pick optimized gcc flags if the user already
1293 provided some on his own (as CXXFLAGS)
1294 - added compile time option to disable processing of All-Notes-Off MIDI
1295 messages
1296 - added compile time options to allow disabling the various audio and
1297 MIDI drivers
1298 - fixed automatic GCC CPU switch detection on PPC
1299 (patch by Ebrahim Mayat)
1300
1301 * Gigasampler format engine:
1302 - extensive synthesis optimization
1303 (reimplementation of EGs and LFO(s), removed synthesis parameter
1304 prerendering and the synthesis parameter matrix in general, splitting
1305 each audio fragment into subfragments now where each subfragment uses
1306 constant pitch and filter coefficients. The volume coefficient is
1307 linearly interpolated inside a subfragment, unless
1308 --disable-interpolate-volume is set.)
1309 - fine tuning of the EG modulation parameters
1310 - improved filter cutoff calculation by adding support for the
1311 following gig parameters: Cutoff freq (used when no cutoff
1312 controller is defined), Control invert, Minimum cutoff, Velocity
1313 curve and Velocity range. The keyboard tracking now scales
1314 cutoff frequency instead of resonance.
1315 - added support for gig parameter Resonance.
1316 - fixed bug in sysex handling (patch by Juan Linietsky)
1317 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1318 which can be overridden with --enable-global-attenuation
1319 - EG fixes: made the length of "attack hold" stage more
1320 accurate. Release stage can now start before attack stage
1321 ends. Cancel release didn't work when sustain was zero. Attack
1322 time now has a minimal value to prevent clicks.
1323 - fixed pitch changes larger than one octave
1324 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1325 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1326 all modes can be altered via standard GM messages, that is CC5 for
1327 altering portamento time, CC65 for enabling / disabling portamento
1328 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1329 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1330 parameter) and crossfade
1331 - added support for the "attenuation controller threshold" gig
1332 parameter
1333 - added smoothing of volume changes caused by control change
1334 messages
1335 - sample loop parameters are now taken from the DimensionRegion
1336 instead of the wave chunk
1337 - fixed keyswitching for v3 gigs with a number of keyswitch splits
1338 not equal to a power of two
1339 - reimplementation of the filter algorithm. The new filter is more
1340 accurate and supports all gig filter types, including bandreject
1341 and lowpass turbo.
1342 - real support for 24 bit samples - samples are not truncated to
1343 16 bits anymore
1344 - support for aftertouch (channel pressure, not polyphonic
1345 aftertouch)
1346 - LFO1 behaviour fixed (dampening from max volume instead of
1347 amplifying from 0)
1348
1349 * LSCP server:
1350 - fixed application exit on broken pipe error (fixes bug #20)
1351 - fixed the notification messages delay due to lack of
1352 network activity (fixes bug #26)
1353 - fixed parser bug which occured on space(s) within device parameters
1354 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1355
1356 * audio driver:
1357 - added aRts audio output driver (by no means RT safe)
1358
1359 * MIDI driver:
1360 - fixed legacy sysex code which caused dispatching of MIDI SysEx
1361 messages several times instead of once
1362 - API extension for MIDI drivers which already supply exact time stamps
1363 for events (i.e. for offline rendering based MIDI drivers)
1364 - added checks for bad MIDI data
1365
1366 * linuxsampler application:
1367 - show available sampler engine types on startup
1368
1369 * general changes:
1370 - support for muting sampler channels and solo mode of the same, two new
1371 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1372 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1373 introduced for this, the behavior is the same like on a mixer console
1374 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1375 --enable-process-muted-channels which can be used to enable the
1376 processing of muted channels.
1377 - support for sostenuto pedal
1378 - support for monitoring the total number of active voices
1379 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1380 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1381 - fixed some memory management errors
1382 - fixed some concurrency problems that could lead to crashes when
1383 LSCP commands were executed
1384 - fixed crash when instrument loading failed previously on the same
1385 sampler channel (fixes bug #36)
1386
1387 Version 0.3.3 (15 July 2005)
1388
1389 * packaging changes:
1390 - fixed compilation with gcc 4.0
1391
1392 * Gigasampler format engine:
1393 - LFO preprocessing was performed even though the respective LFO was
1394 disabled by the instrument patch (minor efficiency fix)
1395 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1396 for volume ramp downs in the same fragment (needed for current voice
1397 stealing implementation) then simply inform the user with a warning
1398 about possible click sounds and reduce the volume ramp down
1399 appropriately instead of cancelling the audio device connection
1400
1401 Version 0.3.2 (24 June 2005)
1402
1403 * packaging changes:
1404 - updated autotools build files to compile on OS X
1405 (conditional compilation of CoreMIDI and MidiShare drivers)
1406 - hand-crafted assembly optimization code can be disabled with
1407 './configure --disable-asm' (definitely not recommended)
1408 - fixed 'make dist' rule to include all necessary files
1409 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1410 (due to 'dist-bzip2' automake option)
1411
1412 * Gigasampler format engine:
1413 - support for the gig parameters for "release velocity response" curves
1414 - fine tuning of the EGADSR envelope
1415 - volume of release triggered samples now depends on note-on velocity,
1416 note length and gig parameter "release trigger decay" instead of
1417 note-off velocity.
1418 - revised voice stealing
1419 (fixes crash and endless loop caused by voice stealing)
1420 - don't reset scale tuning on instrument or audio output device change
1421 - handle key group conflicts right at the beginning of each fragment
1422 instead of when the respective voice is actually launched
1423 (fixes undefined behavior if stolen voices belonged to a key group -
1424 this case was followed by a "killed voice survived" error message)
1425 - fixed minor issue with null/silence samples
1426 (those stole voices even though they don't need a voice at all which
1427 resulted in "voice stealing didn't work out" messages)
1428 - don't reset volume, pan, pitch and MIDI controller values on
1429 instrument or audio output device change
1430
1431 * LSCP server:
1432 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1433 - fixed LSCP event "CHANNEL_INFO" notification
1434 (e.g. did not notify on volume changes or MIDI program change events)
1435
1436 * linuxsampler application:
1437 - added command line parameters --lscp-addr and --lscp-port to override
1438 default IP address and port of LSCP server
1439
1440 Version 0.3.1 (24 May 2005)
1441
1442 * initial release
