File size: 27591 byte(s)
* C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
  a pointer to the launched InstrumentEditor object

1 Version CVS HEAD (?)
2
3 * packaging changes:
4 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
5 causing e.g. the libgig test to fail when
6 "./configure --disable-jack-driver" was used
7 (patch by Alexis Ballier)
8 - fixed compilation with gcc 4.3
9 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
10 - fixed configure so it detects x86_64 (#107)
11 - fixes for building with newer MinGW versions
12 - fix for building with bison 2.4 (#111)
13 - fixed building with libgig installed in a non-standard directory
14
15 * general changes:
16 - bugfix: on some POSIX systems instrument editor plugins refused to
17 load as we used a non-portable Linux specific struct field
18 (fixes bug #70, patch by Ronald Baljeu)
19 - fixed endless loop which occured when loading an instrument editor
20 plugin DLL on Windows systems failed
21 - fixed memory leaks that occurred when liblinuxsampler was unloaded
22 - optimized the SynchronizedConfig class so it doesn't wait
23 unnecessarily long after an update
24 - added support for notifying instrument editors on note-on / note-off
25 events (e.g. to highlight the pressed keys on the virtual keyboard
26 of gigedit)
27 - added support for triggering notes by instrument editors (see above)
28 - be verbose on DLL load errors (on Linux)
29 - fixed di-harmonic triangle LFO implementation (this LFO implementation
30 is only used by very few systems, most pick the int math
31 implementation, which is usually faster)
32 - fixes for audio drivers with varying buffer sizes
33 - experimental support for running LinuxSampler as a DSSI, LV2 and
34 VST plugin
35 - notification events for stream/voice count statistics are now sent
36 only when there are actual changes
37 - added memory ordering constraints to improve stability on
38 multi-core and multi-cpu systems
39 - maximum voices and disk streams can now be altered at runtime
40 - fixed CPU feature detection on x86_64 (maybe fixes #108)
41 - automatic stacktrace mechanism is now turned off by default and can
42 be switched on by command line option "--stacktrace" (the automatic
43 stacktrace mechanism seems to be broken on most systems at the moment)
44 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
45 a pointer to the launched InstrumentEditor object
46
47 * audio driver:
48 - removed the nonsense audio channel constraint (which was hard coded to
49 max. 100 audio channels) for most audio drivers
50 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
51 opposed to the LSCP specs
52 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
53 reflected the wrong value
54 - fixed a memory management bug in ASIO driver
55 - Makefile fix: JACK_CFLAGS wasn't used
56 - JACK: use jack_client_open instead of the deprecated
57 jack_client_new
58 - added (experimental) CoreAudio driver
59
60 * MIDI driver:
61 - added JACK MIDI driver
62 - dispatch bank select as ordinary CC as well, the user might seriously
63 want to (mis)use it for some purpose ("fixed" in all current MIDI
64 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
65
66 * instruments database:
67 - avoid time consuming samples scanning when adding instruments
68 to the instruments database
69 - added support for handling lost files in the instruments database
70 - Implemented option for adding instruments in separate directories
71 in the instruments database
72 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
73
74 * Gigasampler format engine:
75 - fixed a memory leak that could happen when a channel was deleted
76 while notes were playing
77 - made it possible to load an instrument even if the audio thread
78 isn't running
79 - added partial support for the "Controller Triggered" MIDI rule,
80 enough for piano gigs with pedal noise samples
81 - minor fix: only mark FX sends as being modified if really the
82 respective FX send MIDI controller was used
83 - added support for GM global device volume SysEx message
84 (can be selected at compile time to either apply globally to the
85 whole sampler [default] or only to the sampler channels that are
86 connected to the respective MIDI input port the SysEx message arrived
87 on)
88 - bugfix: notes triggered at position 0 in the audio buffer were
89 sometimes wrongly killed in the same buffer, causing no sound to
90 be played
91 - added support for chromatic / drumkit mode Roland GS Sysex message
92 which is usally used to switch a part between chromatic sounds and
93 drumkit sounds (as opposed to their common default setting of MIDI
94 part 10 being a drumkit part and all other ones chromatic parts), in
95 LS however one can switch between the first 16 MIDI instrument maps
96 defined for the sampler
97 - made it possible to create multiple sample channels even if the
98 audio thread isn't running
99 - fixed crash when removing channel with active voices (#116)
100 - bugfix: on sample reference changes (instrument editor), only
101 un-cache the respective sample if it's really not used by any
102 sampler engine anymore
103 - re-cache samples in case they were changed by an instrument editor,
104 e.g. when a sample was added while playing (#82)
105 - fixed hanging notes which occured when note-off event had the exact
106 same time stamp as the voice's note-on event and occured both in the
107 same audio fragment cycle (fixes bug #112)
108 - added support for the "fine tune" and "pitch bend range"
109 instrument-level gig parameters
110 - fixed minor artifacts in pitch bend handling
111 - added support for GS Reset SysEx message
112 - allow gig files to use unlimited downward pitch shifting
113 - added a limit check for upward pitch shifting
114
115 * LSCP server:
116 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
117 react on MIDI data arriving on certain sampler channels (so far only
118 Note-On and Note-Off events are sent via this LSCP event)
119 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
120 react on MIDI data arriving on certain MIDI input devices (so far only
121 Note-On and Note-Off events are sent via this LSCP event)
122 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
123 SET DB_INSTRUMENT FILE_PATH
124 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
125 frontends to send MIDI messages to specific sampler channel
126 - added two additional fields to GET FILE INSTRUMENT INFO command -
127 KEY_BINDINGS and KEYSWITCH_BINDINGS
128 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
129 was incorrect
130 - Optimized the retrieval of the MIDI instrument mappings
131 - added new LSCP command "SET VOICES" to globally alter the maximum
132 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
133 be triggered respectively
134 - added new LSCP command "SET STREAMS" to globally alter the maximum
135 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
136 which will be triggered respectively
137 - bugfix: retry if "select" returns EINTR (this fixes a crash when
138 a gigedit file dialog is opened)
139 - close all connections when LSCPServer is deleted
140
141 * Bug fixes:
142 - fixed a crash which occurs when removing a sampler channel waiting
143 to start instrument loading after another channel
144 - fixed a crash which occurs when removing a sampler channel with
145 instrument loading in progress (bug #113)
146 - fixed termination caused by uncaught exception when adding MIDI
147 instrument with PERSISTENT load mode
148 - fixed possible iterator invalidations when resetting the sampler
149 - fixed memory leaks when issuing the following LSCP commands:
150 GET AUDIO_OUTPUT_DRIVER INFO
151 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
152 GET MIDI_INPUT_DRIVER INFO
153 GET MIDI_INPUT_DRIVER_PARAMETER INFO
154 - fixed possible compilation error when sqlite is not present
155 - fixed orphaned pointers when setting maximum voices limit (bug #118)
156 - fixed crash when changing the audio output device of a sampler
157 channel with loaded instrument and start playing notes
158 - fixed endless loop in Engine::SuspendAll() (bug #120)
159
160
161 Version 0.5.1 (6 December 2007)
162
163 * packaging changes:
164 - added autoconf checks for pthread library
165 - added autoconf check for pthread bug found on certain NPTL-enabled
166 glibc versions (see Gentoo bug report #194076)
167 - added autoconf checks for MS Windows
168
169 * general changes:
170 - bugfix: the thread used by an editor plugin didn't die when the
171 editor closed
172 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
173 out all the space. operator--() did not apply size_mask after
174 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
175 order to avoid problems with the _NonVolatileReader functions.
176 - bugfix: Stream.h: added a missing divide by BytesPerSample in
177 GetWriteSpace(). Since this function is currently only used in
178 the stream's qsort() compare function, it didn't trigger any
179 bugs.
180 - Resampler.h, Synthesizer.h: cubic interpolation now works in
181 24bit mode too. Faster method to read 24bit words on little
182 endian machines (x86): replaced 3 byte reads + shifts with a 1
183 unaligned 32bit read and shift
184 - experimental support for MS Windows (MIDI input via MME, AUDIO
185 output via ASIO)
186 - made handling of SIGINT signal (Ctrl-C) a bit more robust
187 - support for monitoring the total number of active disk streams
188 (new LSCP commands: GET TOTAL_STREAM_COUNT,
189 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
190
191 * AUDIO driver:
192 - added Windows ASIO low latency audio driver
193
194 * MIDI driver:
195 - added MME Windows MIDI driver
196
197 * LSCP server:
198 - added support for Windows style path / filenames, however with
199 forward slash path separators instead of backslash
200 (i.e. "C:/foo/bar.gig")
201 - allow naughty liblscp to send non-string device parameters within
202 apostrophes as well
203 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
204 "LIST FILE INSTRUMENTS <file>" and
205 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
206 about an arbitrary instrument file on the system where the sampler is
207 running on
208
209 Version 0.5.0 (15 October 2007)
210
211 * packaging changes:
212 - config.h is not going to be installed along with liblinuxsampler's
213 API header files anymore
214 - only the API relevant header (and source) files will be exported to
215 the Doxygen API documentation (explicitly listed in Doxyfile.in)
216 - added completely new XCode project files for Mac OSX which is now
217 capable to execute our autoconf environment, thus no need anymore
218 to maintain the compile time configuration file (osx/version.h) for
219 OSX manually (patch by Toshi Nagata)
220 - fixed buggy boolean --enable-foo / --disable-foo configure script
221 parameters
222 - global.h now only covers global definitions that are needed for the
223 C++ API header files, all implementation internal global definitions
224 are now in global_private.h
225 - atomic.h is not exposed to the C++ API anymore
226 - no need to include config.h anymore for using LS's API header files
227 - fixed warnings in API doc generation
228
229 * general changes:
230 - replaced the old, confusing MIDI program change mechanism by a
231 flexible MIDI instrument mapper which allows to map arbitrary
232 (MIDI bank, MIDI program) pairs with arbitrary
233 (engine type, instrument file, file index) triplets which will be
234 loaded on the respective channel when such MIDI program change
235 messages arrive, beside that, each entry allows to define a life-time
236 strategy for the instrument, so the user can define whether the
237 instrument should i.e. be permanently loaded (to be able to switch
238 quickly among sounds) or i.e. loaded just on demand when the
239 respective program change arrives (to safe RAM space), as well as a
240 global volume factor for each entry, so the user can adjust the volume
241 dynamic of his mapped instrument collection without having to modify
242 the instrument files, also one can manage arbitrary amount of such
243 MIDI instrument maps and assign each sampler channel individually
244 a certain map, so that i.e. separation of normal instruments and
245 drumkits is possible
246 - new notification events for tracking changes to audio/MIDI devices,
247 MIDI instrument maps, MIDI instruments, FX sends, global volume.
248 - sampler was limited to load max. 200 instruments in the background
249 due to a constant size RingBuffer FIFO which is now replaced by a
250 dynamic (unlimited) size std::list FIFO
251 - added FX sends, these allow to route audio signals to arbitrary audio
252 output channels for being processed by external effect processors
253 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
254 controllers
255 - global (sampler wide) volume can now be controlled at runtime
256 - Implemented new, improved notification system
257 - fixed compilation errors regarding OSX
258 (patch by Toshi Nagata)
259 - implemented instruments database
260 - added support for escape sequences to the instruments database
261 - added highly experimental support for on-the-fly instrument editing
262 within the sampler's process (by using instrument editor plugins),
263 you'll notice the new "Registered instrument editors:" message on
264 startup, added a new LSCP command:
265 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
266 to spawn a matching instrument editor for the instrument on the
267 given sampler channel, the plugin path can be overridden at compile
268 time with ./configure --enable-plugin-dir=/some/dir
269 - added experimental code for synchronizing instrument editors hosted
270 in the sampler's process to safely edit instruments while playing
271 without a crash (hopefully) by either suspending single regions
272 wherever possible or if unavoidable whole engine(s)
273 - fixed several issues in fundamental "Thread" class: set scheduling
274 policy and priority on thread level, set a minimum stack size for
275 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
276 threads simply inherited properties of starting thread instead of
277 setting their own policy and priority
278 - minor fix in our automatic stack trace mechanism on crashes, the
279 main process did not wait for the stack trace process to finish
280 its output
281 - fixed some minor memory leaks
282 - reenabled assembly features support, at the moment only for
283 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
284 - minor assembly fix in x86 features detection (don't use the PIC
285 register, to avoid relocations in the text segment at runtime)
286 - POSIX callback functions of Thread.h are hidden
287
288 * MIDI driver:
289 - dispatch bank select (MSB and LSB) messages
290
291 * audio driver:
292 - the ALSA audio output driver parameters now reflect the correct
293 parameter value ranges for the respective selected sound card
294 (patch by Till Wimmer, a bit fixed and extended)
295
296 * Gigasampler format engine:
297 - if a filter is used and EG2 finishes before EG1, let the voice
298 die when EG2 has finished (this fixes a problem with clicks and
299 voice starvation for some gigs)
300 - playback is no longer disabled during instrument loading
301 - all notes playing on a channel that changes its instrument keep
302 playing with the old instrument until they get a note off
303 command
304 - EG fix: a release value of zero could cause noises or crash
305 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
306 - EG fine tuning: when attack is zero the EG starts at a level
307 above max sustain level, which means that there is a decay phase
308 even if sustain is 100%
309 - more EG fixes: the level could sometimes go below zero and cause
310 noises or crashes
311 - minor fix of EGDecay (patch by Toshi Nagata)
312 - fixed compiler error when --enable-override-filter-type was
313 supplied to the configure script (fixes #46)
314 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
315 instead of a fix value
316 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
317 127 (solo mode) only kill voices if the respective mode really
318 changed
319
320 * LSCP server:
321 - fixed compile time error for old Bison versions
322 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
323 - parser now supports extended ASCII character set
324 (up to ASCII code 255, i.e. includes now umlauts and accents)
325 - filename arguments in LSCP commands now allow to use escape
326 sequences, that is directly literal as one of: \', \", \\, \n, \r,
327 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
328 code value like \xf2) (fixes bug #24)
329 - the following LSCP commands now also support escape sequences for at
330 least one of their text-based parameters (i.e. name, description):
331 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
332 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
333 "SET DB_INSTRUMENT_DIRECTORY NAME",
334 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
335 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
336 "FIND DB_INSTRUMENT_DIRECTORIES"
337 - returns verbose syntax errors (line and column where syntax error
338 occured, the unexpected character and the actually expected, possible
339 character(s), the latter only if less than 5 possibilities)
340 - made sure that LSCP syntax is not affected by gigedit locale
341 settings
342 - bugfix regarding strings parameter lists: all comma separated lists
343 of strings were treated as being one string containing commas
344 (fixes #57)
345
346 * Bug fixes:
347 - fixed crash occurring on certain LSCP scripts (Bug 39)
348 - another thread safety fix for lscp "load engine" and "set
349 channel audio output device"
350 - fixed a crash which occurs when reassigning the same engine
351 on a sampler channel with connected MIDI device
352 - fixed a crash which occurs when changing the number of ports of a MIDI
353 device connected to a sampler channel to number less then or equal
354 to the index of the port to which the sampler channel is connected.
355 - The previous bindings were not been disconnected when altering
356 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
357 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
358 - The active stream/voice count statistic was incorrect.
359 - notification events were not been sent for some sampler
360 channel changes
361 - added default min and max values to restrict the number of allowed
362 audio output channels and MIDI input ports
363 - the connection to the PCM interface is now closed when destroying
364 an audio output device
365 - files with slash in their path or filename could not be loaded
366
367 * test cases:
368 - updated and fixed (haven't been touched in a while)
369
370 Version 0.4.0 (24 November 2006)
371
372 * packaging changes:
373 - changed deprecated copyright attribute to license; added ldconfig
374 to post-(un)install steps; added devel package for liblinuxsampler;
375 to linuxsampler.spec (RPM)
376 - install necessary development header files for allowing 3rd party
377 applications to link against liblinuxsampler
378 - liblinuxsampler's API documentation can be generated with 'make docs'
379 (Doxygen required)
380 - added benchmark to automatically detect the best triangle LFO
381 implementation (currently either an integer math solution or a
382 di-harmonic approximation), automatic detection can be overriden
383 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
384 configure script argument though (mandatory for cross-compilation)
385 - do not automatically pick optimized gcc flags if the user already
386 provided some on his own (as CXXFLAGS)
387 - added compile time option to disable processing of All-Notes-Off MIDI
388 messages
389 - added compile time options to allow disabling the various audio and
390 MIDI drivers
391 - fixed automatic GCC CPU switch detection on PPC
392 (patch by Ebrahim Mayat)
393
394 * Gigasampler format engine:
395 - extensive synthesis optimization
396 (reimplementation of EGs and LFO(s), removed synthesis parameter
397 prerendering and the synthesis parameter matrix in general, splitting
398 each audio fragment into subfragments now where each subfragment uses
399 constant pitch and filter coefficients. The volume coefficient is
400 linearly interpolated inside a subfragment, unless
401 --disable-interpolate-volume is set.)
402 - fine tuning of the EG modulation parameters
403 - improved filter cutoff calculation by adding support for the
404 following gig parameters: Cutoff freq (used when no cutoff
405 controller is defined), Control invert, Minimum cutoff, Velocity
406 curve and Velocity range. The keyboard tracking now scales
407 cutoff frequency instead of resonance.
408 - added support for gig parameter Resonance.
409 - fixed bug in sysex handling (patch by Juan Linietsky)
410 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
411 which can be overridden with --enable-global-attenuation
412 - EG fixes: made the length of "attack hold" stage more
413 accurate. Release stage can now start before attack stage
414 ends. Cancel release didn't work when sustain was zero. Attack
415 time now has a minimal value to prevent clicks.
416 - fixed pitch changes larger than one octave
417 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
418 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
419 all modes can be altered via standard GM messages, that is CC5 for
420 altering portamento time, CC65 for enabling / disabling portamento
421 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
422 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
423 parameter) and crossfade
424 - added support for the "attenuation controller threshold" gig
425 parameter
426 - added smoothing of volume changes caused by control change
427 messages
428 - sample loop parameters are now taken from the DimensionRegion
429 instead of the wave chunk
430 - fixed keyswitching for v3 gigs with a number of keyswitch splits
431 not equal to a power of two
432 - reimplementation of the filter algorithm. The new filter is more
433 accurate and supports all gig filter types, including bandreject
434 and lowpass turbo.
435 - real support for 24 bit samples - samples are not truncated to
436 16 bits anymore
437 - support for aftertouch (channel pressure, not polyphonic
438 aftertouch)
439 - LFO1 behaviour fixed (dampening from max volume instead of
440 amplifying from 0)
441
442 * LSCP server:
443 - fixed application exit on broken pipe error (fixes bug #20)
444 - fixed the notification messages delay due to lack of
445 network activity (fixes bug #26)
446 - fixed parser bug which occured on space(s) within device parameters
447 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
448
449 * audio driver:
450 - added aRts audio output driver (by no means RT safe)
451
452 * MIDI driver:
453 - fixed legacy sysex code which caused dispatching of MIDI SysEx
454 messages several times instead of once
455 - API extension for MIDI drivers which already supply exact time stamps
456 for events (i.e. for offline rendering based MIDI drivers)
457 - added checks for bad MIDI data
458
459 * linuxsampler application:
460 - show available sampler engine types on startup
461
462 * general changes:
463 - support for muting sampler channels and solo mode of the same, two new
464 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
465 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
466 introduced for this, the behavior is the same like on a mixer console
467 (patch by Grigor Iliev, a bit adjusted). Also added configure option
468 --enable-process-muted-channels which can be used to enable the
469 processing of muted channels.
470 - support for sostenuto pedal
471 - support for monitoring the total number of active voices
472 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
473 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
474 - fixed some memory management errors
475 - fixed some concurrency problems that could lead to crashes when
476 LSCP commands were executed
477 - fixed crash when instrument loading failed previously on the same
478 sampler channel (fixes bug #36)
479
480 Version 0.3.3 (15 July 2005)
481
482 * packaging changes:
483 - fixed compilation with gcc 4.0
484
485 * Gigasampler format engine:
486 - LFO preprocessing was performed even though the respective LFO was
487 disabled by the instrument patch (minor efficiency fix)
488 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
489 for volume ramp downs in the same fragment (needed for current voice
490 stealing implementation) then simply inform the user with a warning
491 about possible click sounds and reduce the volume ramp down
492 appropriately instead of cancelling the audio device connection
493
494 Version 0.3.2 (24 June 2005)
495
496 * packaging changes:
497 - updated autotools build files to compile on OS X
498 (conditional compilation of CoreMIDI and MidiShare drivers)
499 - hand-crafted assembly optimization code can be disabled with
500 './configure --disable-asm' (definitely not recommended)
501 - fixed 'make dist' rule to include all necessary files
502 - require automake (>= 1.5) for 'make -f Makefile.cvs'
503 (due to 'dist-bzip2' automake option)
504
505 * Gigasampler format engine:
506 - support for the gig parameters for "release velocity response" curves
507 - fine tuning of the EGADSR envelope
508 - volume of release triggered samples now depends on note-on velocity,
509 note length and gig parameter "release trigger decay" instead of
510 note-off velocity.
511 - revised voice stealing
512 (fixes crash and endless loop caused by voice stealing)
513 - don't reset scale tuning on instrument or audio output device change
514 - handle key group conflicts right at the beginning of each fragment
515 instead of when the respective voice is actually launched
516 (fixes undefined behavior if stolen voices belonged to a key group -
517 this case was followed by a "killed voice survived" error message)
518 - fixed minor issue with null/silence samples
519 (those stole voices even though they don't need a voice at all which
520 resulted in "voice stealing didn't work out" messages)
521 - don't reset volume, pan, pitch and MIDI controller values on
522 instrument or audio output device change
523
524 * LSCP server:
525 - fixed some crashes (patch by Grigor Iliev, fixes #19)
526 - fixed LSCP event "CHANNEL_INFO" notification
527 (e.g. did not notify on volume changes or MIDI program change events)
528
529 * linuxsampler application:
530 - added command line parameters --lscp-addr and --lscp-port to override
531 default IP address and port of LSCP server
532
533 Version 0.3.1 (24 May 2005)
534
535 * initial release
