Wed Mar 11 19:03:37 2009 UTC (10 years, 9 months ago) by persson
File size: 27458 byte(s)
* allow gig files to use unlimited downward pitch shifting
* added a limit check for upward pitch shifting

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