* Fixed some compiler warnings
* Fixed compilation error when cross-compiling to Mac

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

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

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

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

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

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

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

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

854
855 * general changes:
856 - bugfix: on some POSIX systems instrument editor plugins refused to
857 load as we used a non-portable Linux specific struct field
858 (fixes bug #70, patch by Ronald Baljeu)
859 - fixed endless loop which occured when loading an instrument editor
860 plugin DLL on Windows systems failed
861 - fixed memory leaks that occurred when liblinuxsampler was unloaded
862 - optimized the SynchronizedConfig class so it doesn't wait
863 unnecessarily long after an update
864 - added support for notifying instrument editors on note-on / note-off
865 events (e.g. to highlight the pressed keys on the virtual keyboard
866 of gigedit)
867 - added support for triggering notes by instrument editors (see above)
868 - be verbose on DLL load errors (on Linux)
869 - fixed di-harmonic triangle LFO implementation (this LFO implementation
870 is only used by very few systems, most pick the int math
871 implementation, which is usually faster)
872 - fixes for audio drivers with varying buffer sizes
873 - experimental support for running LinuxSampler as a DSSI, LV2 and
874 VST plugin
875 - notification events for stream/voice count statistics are now sent
876 only when there are actual changes
877 - added memory ordering constraints to improve stability on
878 multi-core and multi-cpu systems
879 - maximum voices and disk streams can now be altered at runtime
880 - fixed CPU feature detection on x86_64 (maybe fixes #108)
881 - automatic stacktrace mechanism is now turned off by default and can
882 be switched on by command line option "--stacktrace" (the automatic
883 stacktrace mechanism seems to be broken on most systems at the moment)
884 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
885 a pointer to the launched InstrumentEditor object
886 - added optional 3rd party user data parameter for following
887 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
888 InstrumentEditor::Launch(),
889 InstrumentManager::LaunchInstrumentEditor()
890 - theoretical fix: made SynchronizedConfig follow C++0x memory
891 model more strictly
892 - fixes for using large audio device buffers
893 - Windows: add the installation directory to the DLL search path
894 when loading an editor plugin (solves problems with VST and
895 gigedit on systems with other GTK versions installed)
896 - updated linuxsampler man page
897
898 * audio driver:
899 - removed the nonsense audio channel constraint (which was hard coded to
900 max. 100 audio channels) for most audio drivers
901 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
902 opposed to the LSCP specs
903 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
904 reflected the wrong value
905 - fixed a memory management bug in ASIO driver
906 - Makefile fix: JACK_CFLAGS wasn't used
907 - JACK: use jack_client_open instead of the deprecated
908 jack_client_new
909 - added (experimental) CoreAudio driver
910 - applied old fixes to the ASIO driver that were included in the
911 previous binary release but accidentally never committed to CVS
912 (fixes #117)
913 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
914 win64)
915 - VST: added support for sample rate and buffer size changes
916 - VST: close editor (Fantasia) when the VST is removed
917 - VST: avoid opening Fantasia more than once for each VST instance
918 - VST: export main function as "main" on Linux too (fix for
919 energyXT)
920 - VST: changed number of output channels from one stereo to 16
921 stereo
922 - added channel routing, fxsends and midi maps to the settings
923 stored in the plugin state
924 - performance optimization of AudioChannel::MixTo() and
925 AudioChannel::CopyTo() methods using GCC vector exensions
926 (if available)
927 - ASIO fixes: avoid initializing the device twice, avoid throwing
928 exception when getting parameters from a disconnected device
929
930 * MIDI driver:
931 - added JACK MIDI driver
932 - dispatch bank select as ordinary CC as well, the user might seriously
933 want to (mis)use it for some purpose ("fixed" in all current MIDI
934 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
935 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
936 CoreMidi or AU
937 - fixed mingw-w64 compilation error in MME driver
938 - made program change handling in MIDI thread real-time safe by
939 moving the logic to a non-RT thread
940 - fixed minor memory leak in ALSA driver
941
942 * instruments database:
943 - avoid time consuming samples scanning when adding instruments
944 to the instruments database
945 - added support for handling lost files in the instruments database
946 - Implemented option for adding instruments in separate directories
947 in the instruments database
948 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
949 - work-around for missing fnmatch function on Windows to make
950 instrument database compilable
951 - added instrument database support on Windows
952 works with both standalone mode and VST plugin.
953 the instruments DB file is located in
954 %USERPROFILE%\.linuxsampler\instruments.db which allows different
955 databases for each windows user
956 if no DB is present it automatically creates the .linuxsampler subdir
957 and then creates an empty DB
958 - fixed recursive import, which was broken on Windows
959
960 * Gigasampler format engine:
961 - fixed a memory leak that could happen when a channel was deleted
962 while notes were playing
963 - made it possible to load an instrument even if the audio thread
964 isn't running
965 - added partial support for the "Controller Triggered" MIDI rule,
966 enough for piano gigs with pedal noise samples
967 - minor fix: only mark FX sends as being modified if really the
968 respective FX send MIDI controller was used
969 - added support for GM global device volume SysEx message
970 (can be selected at compile time to either apply globally to the
971 whole sampler [default] or only to the sampler channels that are
972 connected to the respective MIDI input port the SysEx message arrived
973 on)
974 - bugfix: notes triggered at position 0 in the audio buffer were
975 sometimes wrongly killed in the same buffer, causing no sound to
976 be played
977 - added support for chromatic / drumkit mode Roland GS Sysex message
978 which is usally used to switch a part between chromatic sounds and
979 drumkit sounds (as opposed to their common default setting of MIDI
980 part 10 being a drumkit part and all other ones chromatic parts), in
981 LS however one can switch between the first 16 MIDI instrument maps
982 defined for the sampler
983 - made it possible to create multiple sample channels even if the
984 audio thread isn't running
985 - fixed crash when removing channel with active voices (#116)
986 - bugfix: on sample reference changes (instrument editor), only
987 un-cache the respective sample if it's really not used by any
988 sampler engine anymore
989 - re-cache samples in case they were changed by an instrument editor,
990 e.g. when a sample was added while playing (#82)
991 - fixed hanging notes which occured when note-off event had the exact
992 same time stamp as the voice's note-on event and occured both in the
993 same audio fragment cycle (fixes bug #112)
994 - added support for the "fine tune" and "pitch bend range"
995 instrument-level gig parameters
996 - fixed minor artifacts in pitch bend handling
997 - added support for GS Reset SysEx message
998 - allow gig files to use unlimited downward pitch shifting
999 - added a limit check for upward pitch shifting
1000 - bugfix: sometimes, when playing a note twice fast, the second
1001 note was silent
1002 - fixed crash happening when a pitch bend event arrived at the
1003 same time a new instrument was loading
1004
1005 * LSCP server:
1006 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
1007 react on MIDI data arriving on certain sampler channels (so far only
1008 Note-On and Note-Off events are sent via this LSCP event)
1009 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1010 react on MIDI data arriving on certain MIDI input devices (so far only
1011 Note-On and Note-Off events are sent via this LSCP event)
1012 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
1013 SET DB_INSTRUMENT FILE_PATH
1014 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
1015 frontends to send MIDI messages to specific sampler channel
1016 - added two additional fields to GET FILE INSTRUMENT INFO command -
1017 KEY_BINDINGS and KEYSWITCH_BINDINGS
1018 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1019 was incorrect
1020 - Optimized the retrieval of the MIDI instrument mappings
1021 - added new LSCP command "SET VOICES" to globally alter the maximum
1022 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1023 be triggered respectively
1024 - added new LSCP command "SET STREAMS" to globally alter the maximum
1025 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1026 which will be triggered respectively
1027 - bugfix: retry if "select" returns EINTR (this fixes a crash when
1028 a gigedit file dialog is opened)
1029 - close all connections when LSCPServer is deleted
1030 - hard close of all sockets on exit
1031 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
1032 driver
1033
1034 * Bug fixes:
1035 - fixed a crash which occurs when removing a sampler channel waiting
1036 to start instrument loading after another channel
1037 - fixed a crash which occurs when removing a sampler channel with
1038 instrument loading in progress (bug #113)
1039 - fixed termination caused by uncaught exception when adding MIDI
1040 instrument with PERSISTENT load mode
1041 - fixed possible iterator invalidations when resetting the sampler
1042 - fixed memory leaks when issuing the following LSCP commands:
1043 GET AUDIO_OUTPUT_DRIVER INFO
1044 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
1045 GET MIDI_INPUT_DRIVER INFO
1046 GET MIDI_INPUT_DRIVER_PARAMETER INFO
1047 - fixed possible compilation error when sqlite is not present
1048 - fixed orphaned pointers when setting maximum voices limit (bug #118)
1049 - fixed crash when changing the audio output device of a sampler
1050 channel with loaded instrument and start playing notes
1051 - fixed endless loop in Engine::SuspendAll() (bug #120)
1052 - fixed a low-level atomic load function that was broken on 64-bit
1053 PowerPC, which probably could cause crashes on that platform
1054 - fixed a memory management error which could cause a crash when a
1055 plugin was unloaded
1056 - bugfix: two private structs had the same name, which could cause
1057 problems if the linker chose the wrong constructor
1058 - fixed low-level ConditionServer usage bug that caused lockups on
1059 Windows
1060
1061
1062 Version 0.5.1 (6 December 2007)
1063
1064 * packaging changes:
1065 - added autoconf checks for pthread library
1066 - added autoconf check for pthread bug found on certain NPTL-enabled
1067 glibc versions (see Gentoo bug report #194076)
1068 - added autoconf checks for MS Windows
1069
1070 * general changes:
1071 - bugfix: the thread used by an editor plugin didn't die when the
1072 editor closed
1073 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1074 out all the space. operator--() did not apply size_mask after
1075 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1076 order to avoid problems with the _NonVolatileReader functions.
1077 - bugfix: Stream.h: added a missing divide by BytesPerSample in
1078 GetWriteSpace(). Since this function is currently only used in
1079 the stream's qsort() compare function, it didn't trigger any
1080 bugs.
1081 - Resampler.h, Synthesizer.h: cubic interpolation now works in
1082 24bit mode too. Faster method to read 24bit words on little
1083 endian machines (x86): replaced 3 byte reads + shifts with a 1
1084 unaligned 32bit read and shift
1085 - experimental support for MS Windows (MIDI input via MME, AUDIO
1086 output via ASIO)
1087 - made handling of SIGINT signal (Ctrl-C) a bit more robust
1088 - support for monitoring the total number of active disk streams
1089 (new LSCP commands: GET TOTAL_STREAM_COUNT,
1090 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1091
1092 * AUDIO driver:
1093 - added Windows ASIO low latency audio driver
1094
1095 * MIDI driver:
1096 - added MME Windows MIDI driver
1097
1098 * LSCP server:
1099 - added support for Windows style path / filenames, however with
1100 forward slash path separators instead of backslash
1101 (i.e. "C:/foo/bar.gig")
1102 - allow naughty liblscp to send non-string device parameters within
1103 apostrophes as well
1104 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1105 "LIST FILE INSTRUMENTS <file>" and
1106 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1107 about an arbitrary instrument file on the system where the sampler is
1108 running on
1109
1110 Version 0.5.0 (15 October 2007)
1111
1112 * packaging changes:
1113 - config.h is not going to be installed along with liblinuxsampler's
1114 API header files anymore
1115 - only the API relevant header (and source) files will be exported to
1116 the Doxygen API documentation (explicitly listed in Doxyfile.in)
1117 - added completely new XCode project files for Mac OSX which is now
1118 capable to execute our autoconf environment, thus no need anymore
1119 to maintain the compile time configuration file (osx/version.h) for
1120 OSX manually (patch by Toshi Nagata)
1121 - fixed buggy boolean --enable-foo / --disable-foo configure script
1122 parameters
1123 - global.h now only covers global definitions that are needed for the
1124 C++ API header files, all implementation internal global definitions
1125 are now in global_private.h
1126 - atomic.h is not exposed to the C++ API anymore
1127 - no need to include config.h anymore for using LS's API header files
1128 - fixed warnings in API doc generation
1129
1130 * general changes:
1131 - replaced the old, confusing MIDI program change mechanism by a
1132 flexible MIDI instrument mapper which allows to map arbitrary
1133 (MIDI bank, MIDI program) pairs with arbitrary
1134 (engine type, instrument file, file index) triplets which will be
1135 loaded on the respective channel when such MIDI program change
1136 messages arrive, beside that, each entry allows to define a life-time
1137 strategy for the instrument, so the user can define whether the
1138 instrument should i.e. be permanently loaded (to be able to switch
1139 quickly among sounds) or i.e. loaded just on demand when the
1140 respective program change arrives (to safe RAM space), as well as a
1141 global volume factor for each entry, so the user can adjust the volume
1142 dynamic of his mapped instrument collection without having to modify
1143 the instrument files, also one can manage arbitrary amount of such
1144 MIDI instrument maps and assign each sampler channel individually
1145 a certain map, so that i.e. separation of normal instruments and
1146 drumkits is possible
1147 - new notification events for tracking changes to audio/MIDI devices,
1148 MIDI instrument maps, MIDI instruments, FX sends, global volume.
1149 - sampler was limited to load max. 200 instruments in the background
1150 due to a constant size RingBuffer FIFO which is now replaced by a
1151 dynamic (unlimited) size std::list FIFO
1152 - added FX sends, these allow to route audio signals to arbitrary audio
1153 output channels for being processed by external effect processors
1154 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1155 controllers
1156 - global (sampler wide) volume can now be controlled at runtime
1157 - Implemented new, improved notification system
1158 - fixed compilation errors regarding OSX
1159 (patch by Toshi Nagata)
1160 - implemented instruments database
1161 - added support for escape sequences to the instruments database
1162 - added highly experimental support for on-the-fly instrument editing
1163 within the sampler's process (by using instrument editor plugins),
1164 you'll notice the new "Registered instrument editors:" message on
1165 startup, added a new LSCP command:
1166 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1167 to spawn a matching instrument editor for the instrument on the
1168 given sampler channel, the plugin path can be overridden at compile
1169 time with ./configure --enable-plugin-dir=/some/dir
1170 - added experimental code for synchronizing instrument editors hosted
1171 in the sampler's process to safely edit instruments while playing
1172 without a crash (hopefully) by either suspending single regions
1173 wherever possible or if unavoidable whole engine(s)
1174 - fixed several issues in fundamental "Thread" class: set scheduling
1175 policy and priority on thread level, set a minimum stack size for
1176 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1177 threads simply inherited properties of starting thread instead of
1178 setting their own policy and priority
1179 - minor fix in our automatic stack trace mechanism on crashes, the
1180 main process did not wait for the stack trace process to finish
1181 its output
1182 - fixed some minor memory leaks
1183 - reenabled assembly features support, at the moment only for
1184 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1185 - minor assembly fix in x86 features detection (don't use the PIC
1186 register, to avoid relocations in the text segment at runtime)
1187 - POSIX callback functions of Thread.h are hidden
1188
1189 * MIDI driver:
1190 - dispatch bank select (MSB and LSB) messages
1191
1192 * audio driver:
1193 - the ALSA audio output driver parameters now reflect the correct
1194 parameter value ranges for the respective selected sound card
1195 (patch by Till Wimmer, a bit fixed and extended)
1196
1197 * Gigasampler format engine:
1198 - if a filter is used and EG2 finishes before EG1, let the voice
1199 die when EG2 has finished (this fixes a problem with clicks and
1200 voice starvation for some gigs)
1201 - playback is no longer disabled during instrument loading
1202 - all notes playing on a channel that changes its instrument keep
1203 playing with the old instrument until they get a note off
1204 command
1205 - EG fix: a release value of zero could cause noises or crash
1206 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1207 - EG fine tuning: when attack is zero the EG starts at a level
1208 above max sustain level, which means that there is a decay phase
1209 even if sustain is 100%
1210 - more EG fixes: the level could sometimes go below zero and cause
1211 noises or crashes
1212 - minor fix of EGDecay (patch by Toshi Nagata)
1213 - fixed compiler error when --enable-override-filter-type was
1214 supplied to the configure script (fixes #46)
1215 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1216 instead of a fix value
1217 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1218 127 (solo mode) only kill voices if the respective mode really
1219 changed
1220
1221 * LSCP server:
1222 - fixed compile time error for old Bison versions
1223 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1224 - parser now supports extended ASCII character set
1225 (up to ASCII code 255, i.e. includes now umlauts and accents)
1226 - filename arguments in LSCP commands now allow to use escape
1227 sequences, that is directly literal as one of: \', \", \\, \n, \r,
1228 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1229 code value like \xf2) (fixes bug #24)
1230 - the following LSCP commands now also support escape sequences for at
1231 least one of their text-based parameters (i.e. name, description):
1232 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1233 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1234 "SET DB_INSTRUMENT_DIRECTORY NAME",
1235 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1236 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1237 "FIND DB_INSTRUMENT_DIRECTORIES"
1238 - returns verbose syntax errors (line and column where syntax error
1239 occured, the unexpected character and the actually expected, possible
1240 character(s), the latter only if less than 5 possibilities)
1241 - made sure that LSCP syntax is not affected by gigedit locale
1242 settings
1243 - bugfix regarding strings parameter lists: all comma separated lists
1244 of strings were treated as being one string containing commas
1245 (fixes #57)
1246
1247 * Bug fixes:
1248 - fixed crash occurring on certain LSCP scripts (Bug 39)
1249 - another thread safety fix for lscp "load engine" and "set
1250 channel audio output device"
1251 - fixed a crash which occurs when reassigning the same engine
1252 on a sampler channel with connected MIDI device
1253 - fixed a crash which occurs when changing the number of ports of a MIDI
1254 device connected to a sampler channel to number less then or equal
1255 to the index of the port to which the sampler channel is connected.
1256 - The previous bindings were not been disconnected when altering
1257 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1258 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1259 - The active stream/voice count statistic was incorrect.
1260 - notification events were not been sent for some sampler
1261 channel changes
1262 - added default min and max values to restrict the number of allowed
1263 audio output channels and MIDI input ports
1264 - the connection to the PCM interface is now closed when destroying
1265 an audio output device
1266 - files with slash in their path or filename could not be loaded
1267
1268 * test cases:
1269 - updated and fixed (haven't been touched in a while)
1270
1271 Version 0.4.0 (24 November 2006)
1272
1273 * packaging changes:
1274 - changed deprecated copyright attribute to license; added ldconfig
1275 to post-(un)install steps; added devel package for liblinuxsampler;
1276 to linuxsampler.spec (RPM)
1277 - install necessary development header files for allowing 3rd party
1278 applications to link against liblinuxsampler
1279 - liblinuxsampler's API documentation can be generated with 'make docs'
1280 (Doxygen required)
1281 - added benchmark to automatically detect the best triangle LFO
1282 implementation (currently either an integer math solution or a
1283 di-harmonic approximation), automatic detection can be overriden
1284 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1285 configure script argument though (mandatory for cross-compilation)
1286 - do not automatically pick optimized gcc flags if the user already
1287 provided some on his own (as CXXFLAGS)
1288 - added compile time option to disable processing of All-Notes-Off MIDI
1289 messages
1290 - added compile time options to allow disabling the various audio and
1291 MIDI drivers
1292 - fixed automatic GCC CPU switch detection on PPC
1293 (patch by Ebrahim Mayat)
1294
1295 * Gigasampler format engine:
1296 - extensive synthesis optimization
1297 (reimplementation of EGs and LFO(s), removed synthesis parameter
1298 prerendering and the synthesis parameter matrix in general, splitting
1299 each audio fragment into subfragments now where each subfragment uses
1300 constant pitch and filter coefficients. The volume coefficient is
1301 linearly interpolated inside a subfragment, unless
1302 --disable-interpolate-volume is set.)
1303 - fine tuning of the EG modulation parameters
1304 - improved filter cutoff calculation by adding support for the
1305 following gig parameters: Cutoff freq (used when no cutoff
1306 controller is defined), Control invert, Minimum cutoff, Velocity
1307 curve and Velocity range. The keyboard tracking now scales
1308 cutoff frequency instead of resonance.
1309 - added support for gig parameter Resonance.
1310 - fixed bug in sysex handling (patch by Juan Linietsky)
1311 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1312 which can be overridden with --enable-global-attenuation
1313 - EG fixes: made the length of "attack hold" stage more
1314 accurate. Release stage can now start before attack stage
1315 ends. Cancel release didn't work when sustain was zero. Attack
1316 time now has a minimal value to prevent clicks.
1317 - fixed pitch changes larger than one octave
1318 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1319 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1320 all modes can be altered via standard GM messages, that is CC5 for
1321 altering portamento time, CC65 for enabling / disabling portamento
1322 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1323 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1324 parameter) and crossfade
1325 - added support for the "attenuation controller threshold" gig
1326 parameter
1327 - added smoothing of volume changes caused by control change
1328 messages
1329 - sample loop parameters are now taken from the DimensionRegion
1330 instead of the wave chunk
1331 - fixed keyswitching for v3 gigs with a number of keyswitch splits
1332 not equal to a power of two
1333 - reimplementation of the filter algorithm. The new filter is more
1334 accurate and supports all gig filter types, including bandreject
1335 and lowpass turbo.
1336 - real support for 24 bit samples - samples are not truncated to
1337 16 bits anymore
1338 - support for aftertouch (channel pressure, not polyphonic
1339 aftertouch)
1340 - LFO1 behaviour fixed (dampening from max volume instead of
1341 amplifying from 0)
1342
1343 * LSCP server:
1344 - fixed application exit on broken pipe error (fixes bug #20)
1345 - fixed the notification messages delay due to lack of
1346 network activity (fixes bug #26)
1347 - fixed parser bug which occured on space(s) within device parameters
1348 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1349
1350 * audio driver:
1351 - added aRts audio output driver (by no means RT safe)
1352
1353 * MIDI driver:
1354 - fixed legacy sysex code which caused dispatching of MIDI SysEx
1355 messages several times instead of once
1356 - API extension for MIDI drivers which already supply exact time stamps
1357 for events (i.e. for offline rendering based MIDI drivers)
1358 - added checks for bad MIDI data
1359
1360 * linuxsampler application:
1361 - show available sampler engine types on startup
1362
1363 * general changes:
1364 - support for muting sampler channels and solo mode of the same, two new
1365 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1366 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1367 introduced for this, the behavior is the same like on a mixer console
1368 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1369 --enable-process-muted-channels which can be used to enable the
1370 processing of muted channels.
1371 - support for sostenuto pedal
1372 - support for monitoring the total number of active voices
1373 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1374 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1375 - fixed some memory management errors
1376 - fixed some concurrency problems that could lead to crashes when
1377 LSCP commands were executed
1378 - fixed crash when instrument loading failed previously on the same
1379 sampler channel (fixes bug #36)
1380
1381 Version 0.3.3 (15 July 2005)
1382
1383 * packaging changes:
1384 - fixed compilation with gcc 4.0
1385
1386 * Gigasampler format engine:
1387 - LFO preprocessing was performed even though the respective LFO was
1388 disabled by the instrument patch (minor efficiency fix)
1389 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1390 for volume ramp downs in the same fragment (needed for current voice
1391 stealing implementation) then simply inform the user with a warning
1392 about possible click sounds and reduce the volume ramp down
1393 appropriately instead of cancelling the audio device connection
1394
1395 Version 0.3.2 (24 June 2005)
1396
1397 * packaging changes:
1398 - updated autotools build files to compile on OS X
1399 (conditional compilation of CoreMIDI and MidiShare drivers)
1400 - hand-crafted assembly optimization code can be disabled with
1401 './configure --disable-asm' (definitely not recommended)
1402 - fixed 'make dist' rule to include all necessary files
1403 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1404 (due to 'dist-bzip2' automake option)
1405
1406 * Gigasampler format engine:
1407 - support for the gig parameters for "release velocity response" curves
1408 - fine tuning of the EGADSR envelope
1409 - volume of release triggered samples now depends on note-on velocity,
1410 note length and gig parameter "release trigger decay" instead of
1411 note-off velocity.
1412 - revised voice stealing
1413 (fixes crash and endless loop caused by voice stealing)
1414 - don't reset scale tuning on instrument or audio output device change
1415 - handle key group conflicts right at the beginning of each fragment
1416 instead of when the respective voice is actually launched
1417 (fixes undefined behavior if stolen voices belonged to a key group -
1418 this case was followed by a "killed voice survived" error message)
1419 - fixed minor issue with null/silence samples
1420 (those stole voices even though they don't need a voice at all which
1421 resulted in "voice stealing didn't work out" messages)
1422 - don't reset volume, pan, pitch and MIDI controller values on
1423 instrument or audio output device change
1424
1425 * LSCP server:
1426 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1427 - fixed LSCP event "CHANNEL_INFO" notification
1428 (e.g. did not notify on volume changes or MIDI program change events)
1429
1430 * linuxsampler application:
1431 - added command line parameters --lscp-addr and --lscp-port to override
1432 default IP address and port of LSCP server
1433
1434 Version 0.3.1 (24 May 2005)
1435
1436 * initial release
