* bugfix: sometimes, when playing a note twice fast, the second note
  was silent

1 Version CVS HEAD (?)
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 - minor fix in configure for mmsystem.h detection on MinGW
15 - Windows: look for editor plugins and Fantasia using base
16 directory of liblinuxsampler dll
17 - configure script fix: removed unconditional use of SSE
19 * general changes:
20 - bugfix: on some POSIX systems instrument editor plugins refused to
21 load as we used a non-portable Linux specific struct field
22 (fixes bug #70, patch by Ronald Baljeu)
23 - fixed endless loop which occured when loading an instrument editor
24 plugin DLL on Windows systems failed
25 - fixed memory leaks that occurred when liblinuxsampler was unloaded
26 - optimized the SynchronizedConfig class so it doesn't wait
27 unnecessarily long after an update
28 - added support for notifying instrument editors on note-on / note-off
29 events (e.g. to highlight the pressed keys on the virtual keyboard
30 of gigedit)
31 - added support for triggering notes by instrument editors (see above)
32 - be verbose on DLL load errors (on Linux)
33 - fixed di-harmonic triangle LFO implementation (this LFO implementation
34 is only used by very few systems, most pick the int math
35 implementation, which is usually faster)
36 - fixes for audio drivers with varying buffer sizes
37 - experimental support for running LinuxSampler as a DSSI, LV2 and
38 VST plugin
39 - notification events for stream/voice count statistics are now sent
40 only when there are actual changes
41 - added memory ordering constraints to improve stability on
42 multi-core and multi-cpu systems
43 - maximum voices and disk streams can now be altered at runtime
44 - fixed CPU feature detection on x86_64 (maybe fixes #108)
45 - automatic stacktrace mechanism is now turned off by default and can
46 be switched on by command line option "--stacktrace" (the automatic
47 stacktrace mechanism seems to be broken on most systems at the moment)
48 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
49 a pointer to the launched InstrumentEditor object
50 - added optional 3rd party user data parameter for following
51 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
52 InstrumentEditor::Launch(),
53 InstrumentManager::LaunchInstrumentEditor()
54 - theoretical fix: made SynchronizedConfig follow C++0x memory
55 model more strictly
56 - fixes for using large audio device buffers
58 * audio driver:
59 - removed the nonsense audio channel constraint (which was hard coded to
60 max. 100 audio channels) for most audio drivers
61 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
62 opposed to the LSCP specs
63 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
64 reflected the wrong value
65 - fixed a memory management bug in ASIO driver
66 - Makefile fix: JACK_CFLAGS wasn't used
67 - JACK: use jack_client_open instead of the deprecated
68 jack_client_new
69 - added (experimental) CoreAudio driver
70 - applied old fixes to the ASIO driver that were included in the
71 previous binary release but accidentally never committed to CVS
72 (fixes #117)
73 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
74 win64)
75 - VST: added support for sample rate and buffer size changes
76 - VST: close editor (Fantasia) when the VST is removed
78 * MIDI driver:
79 - added JACK MIDI driver
80 - dispatch bank select as ordinary CC as well, the user might seriously
81 want to (mis)use it for some purpose ("fixed" in all current MIDI
82 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
83 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
84 CoreMidi or AU
85 - fixed mingw-w64 compilation error in MME driver
87 * instruments database:
88 - avoid time consuming samples scanning when adding instruments
89 to the instruments database
90 - added support for handling lost files in the instruments database
91 - Implemented option for adding instruments in separate directories
92 in the instruments database
93 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
95 * Gigasampler format engine:
96 - fixed a memory leak that could happen when a channel was deleted
97 while notes were playing
98 - made it possible to load an instrument even if the audio thread
99 isn't running
100 - added partial support for the "Controller Triggered" MIDI rule,
101 enough for piano gigs with pedal noise samples
102 - minor fix: only mark FX sends as being modified if really the
103 respective FX send MIDI controller was used
104 - added support for GM global device volume SysEx message
105 (can be selected at compile time to either apply globally to the
106 whole sampler [default] or only to the sampler channels that are
107 connected to the respective MIDI input port the SysEx message arrived
108 on)
109 - bugfix: notes triggered at position 0 in the audio buffer were
110 sometimes wrongly killed in the same buffer, causing no sound to
111 be played
112 - added support for chromatic / drumkit mode Roland GS Sysex message
113 which is usally used to switch a part between chromatic sounds and
114 drumkit sounds (as opposed to their common default setting of MIDI
115 part 10 being a drumkit part and all other ones chromatic parts), in
116 LS however one can switch between the first 16 MIDI instrument maps
117 defined for the sampler
118 - made it possible to create multiple sample channels even if the
119 audio thread isn't running
120 - fixed crash when removing channel with active voices (#116)
121 - bugfix: on sample reference changes (instrument editor), only
122 un-cache the respective sample if it's really not used by any
123 sampler engine anymore
124 - re-cache samples in case they were changed by an instrument editor,
125 e.g. when a sample was added while playing (#82)
126 - fixed hanging notes which occured when note-off event had the exact
127 same time stamp as the voice's note-on event and occured both in the
128 same audio fragment cycle (fixes bug #112)
129 - added support for the "fine tune" and "pitch bend range"
130 instrument-level gig parameters
131 - fixed minor artifacts in pitch bend handling
132 - added support for GS Reset SysEx message
133 - allow gig files to use unlimited downward pitch shifting
134 - added a limit check for upward pitch shifting
135 - bugfix: sometimes, when playing a note twice fast, the second
136 note was silent
138 * LSCP server:
139 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
140 react on MIDI data arriving on certain sampler channels (so far only
141 Note-On and Note-Off events are sent via this LSCP event)
142 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
143 react on MIDI data arriving on certain MIDI input devices (so far only
144 Note-On and Note-Off events are sent via this LSCP event)
145 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
147 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
148 frontends to send MIDI messages to specific sampler channel
149 - added two additional fields to GET FILE INSTRUMENT INFO command -
151 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
152 was incorrect
153 - Optimized the retrieval of the MIDI instrument mappings
154 - added new LSCP command "SET VOICES" to globally alter the maximum
155 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
156 be triggered respectively
157 - added new LSCP command "SET STREAMS" to globally alter the maximum
158 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
159 which will be triggered respectively
160 - bugfix: retry if "select" returns EINTR (this fixes a crash when
161 a gigedit file dialog is opened)
162 - close all connections when LSCPServer is deleted
163 - hard close of all sockets on exit
164 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
165 driver
167 * Bug fixes:
168 - fixed a crash which occurs when removing a sampler channel waiting
169 to start instrument loading after another channel
170 - fixed a crash which occurs when removing a sampler channel with
171 instrument loading in progress (bug #113)
172 - fixed termination caused by uncaught exception when adding MIDI
173 instrument with PERSISTENT load mode
174 - fixed possible iterator invalidations when resetting the sampler
175 - fixed memory leaks when issuing the following LSCP commands:
180 - fixed possible compilation error when sqlite is not present
181 - fixed orphaned pointers when setting maximum voices limit (bug #118)
182 - fixed crash when changing the audio output device of a sampler
183 channel with loaded instrument and start playing notes
184 - fixed endless loop in Engine::SuspendAll() (bug #120)
185 - fixed a low-level atomic load function that was broken on 64-bit
186 PowerPC, which probably could cause crashes on that platform
187 - fixed a memory management error which could cause a crash when a
188 plugin was unloaded
189 - bugfix: two private structs had the same name, which could cause
190 problems if the linker chose the wrong constructor
193 Version 0.5.1 (6 December 2007)
195 * packaging changes:
196 - added autoconf checks for pthread library
197 - added autoconf check for pthread bug found on certain NPTL-enabled
198 glibc versions (see Gentoo bug report #194076)
199 - added autoconf checks for MS Windows
201 * general changes:
202 - bugfix: the thread used by an editor plugin didn't die when the
203 editor closed
204 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
205 out all the space. operator--() did not apply size_mask after
206 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
207 order to avoid problems with the _NonVolatileReader functions.
208 - bugfix: Stream.h: added a missing divide by BytesPerSample in
209 GetWriteSpace(). Since this function is currently only used in
210 the stream's qsort() compare function, it didn't trigger any
211 bugs.
212 - Resampler.h, Synthesizer.h: cubic interpolation now works in
213 24bit mode too. Faster method to read 24bit words on little
214 endian machines (x86): replaced 3 byte reads + shifts with a 1
215 unaligned 32bit read and shift
216 - experimental support for MS Windows (MIDI input via MME, AUDIO
217 output via ASIO)
218 - made handling of SIGINT signal (Ctrl-C) a bit more robust
219 - support for monitoring the total number of active disk streams
220 (new LSCP commands: GET TOTAL_STREAM_COUNT,
223 * AUDIO driver:
224 - added Windows ASIO low latency audio driver
226 * MIDI driver:
227 - added MME Windows MIDI driver
229 * LSCP server:
230 - added support for Windows style path / filenames, however with
231 forward slash path separators instead of backslash
232 (i.e. "C:/foo/bar.gig")
233 - allow naughty liblscp to send non-string device parameters within
234 apostrophes as well
235 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
236 "LIST FILE INSTRUMENTS <file>" and
237 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
238 about an arbitrary instrument file on the system where the sampler is
239 running on
241 Version 0.5.0 (15 October 2007)
243 * packaging changes:
244 - config.h is not going to be installed along with liblinuxsampler's
245 API header files anymore
246 - only the API relevant header (and source) files will be exported to
247 the Doxygen API documentation (explicitly listed in Doxyfile.in)
248 - added completely new XCode project files for Mac OSX which is now
249 capable to execute our autoconf environment, thus no need anymore
250 to maintain the compile time configuration file (osx/version.h) for
251 OSX manually (patch by Toshi Nagata)
252 - fixed buggy boolean --enable-foo / --disable-foo configure script
253 parameters
254 - global.h now only covers global definitions that are needed for the
255 C++ API header files, all implementation internal global definitions
256 are now in global_private.h
257 - atomic.h is not exposed to the C++ API anymore
258 - no need to include config.h anymore for using LS's API header files
259 - fixed warnings in API doc generation
261 * general changes:
262 - replaced the old, confusing MIDI program change mechanism by a
263 flexible MIDI instrument mapper which allows to map arbitrary
264 (MIDI bank, MIDI program) pairs with arbitrary
265 (engine type, instrument file, file index) triplets which will be
266 loaded on the respective channel when such MIDI program change
267 messages arrive, beside that, each entry allows to define a life-time
268 strategy for the instrument, so the user can define whether the
269 instrument should i.e. be permanently loaded (to be able to switch
270 quickly among sounds) or i.e. loaded just on demand when the
271 respective program change arrives (to safe RAM space), as well as a
272 global volume factor for each entry, so the user can adjust the volume
273 dynamic of his mapped instrument collection without having to modify
274 the instrument files, also one can manage arbitrary amount of such
275 MIDI instrument maps and assign each sampler channel individually
276 a certain map, so that i.e. separation of normal instruments and
277 drumkits is possible
278 - new notification events for tracking changes to audio/MIDI devices,
279 MIDI instrument maps, MIDI instruments, FX sends, global volume.
280 - sampler was limited to load max. 200 instruments in the background
281 due to a constant size RingBuffer FIFO which is now replaced by a
282 dynamic (unlimited) size std::list FIFO
283 - added FX sends, these allow to route audio signals to arbitrary audio
284 output channels for being processed by external effect processors
285 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
286 controllers
287 - global (sampler wide) volume can now be controlled at runtime
288 - Implemented new, improved notification system
289 - fixed compilation errors regarding OSX
290 (patch by Toshi Nagata)
291 - implemented instruments database
292 - added support for escape sequences to the instruments database
293 - added highly experimental support for on-the-fly instrument editing
294 within the sampler's process (by using instrument editor plugins),
295 you'll notice the new "Registered instrument editors:" message on
296 startup, added a new LSCP command:
297 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
298 to spawn a matching instrument editor for the instrument on the
299 given sampler channel, the plugin path can be overridden at compile
300 time with ./configure --enable-plugin-dir=/some/dir
301 - added experimental code for synchronizing instrument editors hosted
302 in the sampler's process to safely edit instruments while playing
303 without a crash (hopefully) by either suspending single regions
304 wherever possible or if unavoidable whole engine(s)
305 - fixed several issues in fundamental "Thread" class: set scheduling
306 policy and priority on thread level, set a minimum stack size for
307 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
308 threads simply inherited properties of starting thread instead of
309 setting their own policy and priority
310 - minor fix in our automatic stack trace mechanism on crashes, the
311 main process did not wait for the stack trace process to finish
312 its output
313 - fixed some minor memory leaks
314 - reenabled assembly features support, at the moment only for
315 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
316 - minor assembly fix in x86 features detection (don't use the PIC
317 register, to avoid relocations in the text segment at runtime)
318 - POSIX callback functions of Thread.h are hidden
320 * MIDI driver:
321 - dispatch bank select (MSB and LSB) messages
323 * audio driver:
324 - the ALSA audio output driver parameters now reflect the correct
325 parameter value ranges for the respective selected sound card
326 (patch by Till Wimmer, a bit fixed and extended)
328 * Gigasampler format engine:
329 - if a filter is used and EG2 finishes before EG1, let the voice
330 die when EG2 has finished (this fixes a problem with clicks and
331 voice starvation for some gigs)
332 - playback is no longer disabled during instrument loading
333 - all notes playing on a channel that changes its instrument keep
334 playing with the old instrument until they get a note off
335 command
336 - EG fix: a release value of zero could cause noises or crash
337 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
338 - EG fine tuning: when attack is zero the EG starts at a level
339 above max sustain level, which means that there is a decay phase
340 even if sustain is 100%
341 - more EG fixes: the level could sometimes go below zero and cause
342 noises or crashes
343 - minor fix of EGDecay (patch by Toshi Nagata)
344 - fixed compiler error when --enable-override-filter-type was
345 supplied to the configure script (fixes #46)
346 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
347 instead of a fix value
348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
349 127 (solo mode) only kill voices if the respective mode really
350 changed
352 * LSCP server:
353 - fixed compile time error for old Bison versions
354 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
355 - parser now supports extended ASCII character set
356 (up to ASCII code 255, i.e. includes now umlauts and accents)
357 - filename arguments in LSCP commands now allow to use escape
358 sequences, that is directly literal as one of: \', \", \\, \n, \r,
359 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
360 code value like \xf2) (fixes bug #24)
361 - the following LSCP commands now also support escape sequences for at
362 least one of their text-based parameters (i.e. name, description):
369 - returns verbose syntax errors (line and column where syntax error
370 occured, the unexpected character and the actually expected, possible
371 character(s), the latter only if less than 5 possibilities)
372 - made sure that LSCP syntax is not affected by gigedit locale
373 settings
374 - bugfix regarding strings parameter lists: all comma separated lists
375 of strings were treated as being one string containing commas
376 (fixes #57)
378 * Bug fixes:
379 - fixed crash occurring on certain LSCP scripts (Bug 39)
380 - another thread safety fix for lscp "load engine" and "set
381 channel audio output device"
382 - fixed a crash which occurs when reassigning the same engine
383 on a sampler channel with connected MIDI device
384 - fixed a crash which occurs when changing the number of ports of a MIDI
385 device connected to a sampler channel to number less then or equal
386 to the index of the port to which the sampler channel is connected.
387 - The previous bindings were not been disconnected when altering
388 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
389 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
390 - The active stream/voice count statistic was incorrect.
391 - notification events were not been sent for some sampler
392 channel changes
393 - added default min and max values to restrict the number of allowed
394 audio output channels and MIDI input ports
395 - the connection to the PCM interface is now closed when destroying
396 an audio output device
397 - files with slash in their path or filename could not be loaded
399 * test cases:
400 - updated and fixed (haven't been touched in a while)
402 Version 0.4.0 (24 November 2006)
404 * packaging changes:
405 - changed deprecated copyright attribute to license; added ldconfig
406 to post-(un)install steps; added devel package for liblinuxsampler;
407 to linuxsampler.spec (RPM)
408 - install necessary development header files for allowing 3rd party
409 applications to link against liblinuxsampler
410 - liblinuxsampler's API documentation can be generated with 'make docs'
411 (Doxygen required)
412 - added benchmark to automatically detect the best triangle LFO
413 implementation (currently either an integer math solution or a
414 di-harmonic approximation), automatic detection can be overriden
415 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
416 configure script argument though (mandatory for cross-compilation)
417 - do not automatically pick optimized gcc flags if the user already
418 provided some on his own (as CXXFLAGS)
419 - added compile time option to disable processing of All-Notes-Off MIDI
420 messages
421 - added compile time options to allow disabling the various audio and
422 MIDI drivers
423 - fixed automatic GCC CPU switch detection on PPC
424 (patch by Ebrahim Mayat)
426 * Gigasampler format engine:
427 - extensive synthesis optimization
428 (reimplementation of EGs and LFO(s), removed synthesis parameter
429 prerendering and the synthesis parameter matrix in general, splitting
430 each audio fragment into subfragments now where each subfragment uses
431 constant pitch and filter coefficients. The volume coefficient is
432 linearly interpolated inside a subfragment, unless
433 --disable-interpolate-volume is set.)
434 - fine tuning of the EG modulation parameters
435 - improved filter cutoff calculation by adding support for the
436 following gig parameters: Cutoff freq (used when no cutoff
437 controller is defined), Control invert, Minimum cutoff, Velocity
438 curve and Velocity range. The keyboard tracking now scales
439 cutoff frequency instead of resonance.
440 - added support for gig parameter Resonance.
441 - fixed bug in sysex handling (patch by Juan Linietsky)
442 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
443 which can be overridden with --enable-global-attenuation
444 - EG fixes: made the length of "attack hold" stage more
445 accurate. Release stage can now start before attack stage
446 ends. Cancel release didn't work when sustain was zero. Attack
447 time now has a minimal value to prevent clicks.
448 - fixed pitch changes larger than one octave
449 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
450 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
451 all modes can be altered via standard GM messages, that is CC5 for
452 altering portamento time, CC65 for enabling / disabling portamento
453 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
454 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
455 parameter) and crossfade
456 - added support for the "attenuation controller threshold" gig
457 parameter
458 - added smoothing of volume changes caused by control change
459 messages
460 - sample loop parameters are now taken from the DimensionRegion
461 instead of the wave chunk
462 - fixed keyswitching for v3 gigs with a number of keyswitch splits
463 not equal to a power of two
464 - reimplementation of the filter algorithm. The new filter is more
465 accurate and supports all gig filter types, including bandreject
466 and lowpass turbo.
467 - real support for 24 bit samples - samples are not truncated to
468 16 bits anymore
469 - support for aftertouch (channel pressure, not polyphonic
470 aftertouch)
471 - LFO1 behaviour fixed (dampening from max volume instead of
472 amplifying from 0)
474 * LSCP server:
475 - fixed application exit on broken pipe error (fixes bug #20)
476 - fixed the notification messages delay due to lack of
477 network activity (fixes bug #26)
478 - fixed parser bug which occured on space(s) within device parameters
481 * audio driver:
482 - added aRts audio output driver (by no means RT safe)
484 * MIDI driver:
485 - fixed legacy sysex code which caused dispatching of MIDI SysEx
486 messages several times instead of once
487 - API extension for MIDI drivers which already supply exact time stamps
488 for events (i.e. for offline rendering based MIDI drivers)
489 - added checks for bad MIDI data
491 * linuxsampler application:
492 - show available sampler engine types on startup
494 * general changes:
495 - support for muting sampler channels and solo mode of the same, two new
496 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
497 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
498 introduced for this, the behavior is the same like on a mixer console
499 (patch by Grigor Iliev, a bit adjusted). Also added configure option
500 --enable-process-muted-channels which can be used to enable the
501 processing of muted channels.
502 - support for sostenuto pedal
503 - support for monitoring the total number of active voices
506 - fixed some memory management errors
507 - fixed some concurrency problems that could lead to crashes when
508 LSCP commands were executed
509 - fixed crash when instrument loading failed previously on the same
510 sampler channel (fixes bug #36)
512 Version 0.3.3 (15 July 2005)
514 * packaging changes:
515 - fixed compilation with gcc 4.0
517 * Gigasampler format engine:
518 - LFO preprocessing was performed even though the respective LFO was
519 disabled by the instrument patch (minor efficiency fix)
520 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
521 for volume ramp downs in the same fragment (needed for current voice
522 stealing implementation) then simply inform the user with a warning
523 about possible click sounds and reduce the volume ramp down
524 appropriately instead of cancelling the audio device connection
526 Version 0.3.2 (24 June 2005)
528 * packaging changes:
529 - updated autotools build files to compile on OS X
530 (conditional compilation of CoreMIDI and MidiShare drivers)
531 - hand-crafted assembly optimization code can be disabled with
532 './configure --disable-asm' (definitely not recommended)
533 - fixed 'make dist' rule to include all necessary files
534 - require automake (>= 1.5) for 'make -f Makefile.cvs'
535 (due to 'dist-bzip2' automake option)
537 * Gigasampler format engine:
538 - support for the gig parameters for "release velocity response" curves
539 - fine tuning of the EGADSR envelope
540 - volume of release triggered samples now depends on note-on velocity,
541 note length and gig parameter "release trigger decay" instead of
542 note-off velocity.
543 - revised voice stealing
544 (fixes crash and endless loop caused by voice stealing)
545 - don't reset scale tuning on instrument or audio output device change
546 - handle key group conflicts right at the beginning of each fragment
547 instead of when the respective voice is actually launched
548 (fixes undefined behavior if stolen voices belonged to a key group -
549 this case was followed by a "killed voice survived" error message)
550 - fixed minor issue with null/silence samples
551 (those stole voices even though they don't need a voice at all which
552 resulted in "voice stealing didn't work out" messages)
553 - don't reset volume, pan, pitch and MIDI controller values on
554 instrument or audio output device change
556 * LSCP server:
557 - fixed some crashes (patch by Grigor Iliev, fixes #19)
558 - fixed LSCP event "CHANNEL_INFO" notification
559 (e.g. did not notify on volume changes or MIDI program change events)
561 * linuxsampler application:
562 - added command line parameters --lscp-addr and --lscp-port to override
563 default IP address and port of LSCP server
565 Version 0.3.1 (24 May 2005)
567 * initial release
