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 - minor fix in configure for mmsystem.h detection on MinGW
15
16 * general changes:
17 - bugfix: on some POSIX systems instrument editor plugins refused to
18 load as we used a non-portable Linux specific struct field
19 (fixes bug #70, patch by Ronald Baljeu)
20 - fixed endless loop which occured when loading an instrument editor
21 plugin DLL on Windows systems failed
22 - fixed memory leaks that occurred when liblinuxsampler was unloaded
23 - optimized the SynchronizedConfig class so it doesn't wait
24 unnecessarily long after an update
25 - added support for notifying instrument editors on note-on / note-off
26 events (e.g. to highlight the pressed keys on the virtual keyboard
27 of gigedit)
28 - added support for triggering notes by instrument editors (see above)
29 - be verbose on DLL load errors (on Linux)
30 - fixed di-harmonic triangle LFO implementation (this LFO implementation
31 is only used by very few systems, most pick the int math
32 implementation, which is usually faster)
33 - fixes for audio drivers with varying buffer sizes
34 - experimental support for running LinuxSampler as a DSSI, LV2 and
35 VST plugin
36 - notification events for stream/voice count statistics are now sent
37 only when there are actual changes
38 - added memory ordering constraints to improve stability on
39 multi-core and multi-cpu systems
40 - maximum voices and disk streams can now be altered at runtime
41 - fixed CPU feature detection on x86_64 (maybe fixes #108)
42 - automatic stacktrace mechanism is now turned off by default and can
43 be switched on by command line option "--stacktrace" (the automatic
44 stacktrace mechanism seems to be broken on most systems at the moment)
45 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
46 a pointer to the launched InstrumentEditor object
47 - added optional 3rd party user data parameter for following
48 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
49 InstrumentEditor::Launch(),
50 InstrumentManager::LaunchInstrumentEditor()
51 - theoretical fix: made SynchronizedConfig follow C++0x memory
52 model more strictly
53 - fixes for using large audio device buffers
54
55 * audio driver:
56 - removed the nonsense audio channel constraint (which was hard coded to
57 max. 100 audio channels) for most audio drivers
58 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
59 opposed to the LSCP specs
60 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
61 reflected the wrong value
62 - fixed a memory management bug in ASIO driver
63 - Makefile fix: JACK_CFLAGS wasn't used
64 - JACK: use jack_client_open instead of the deprecated
65 jack_client_new
66 - added (experimental) CoreAudio driver
67 - applied old fixes to the ASIO driver that were included in the
68 previous binary release but accidentally never committed to CVS
69 (fixes #117)
70 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
71 win64)
72 - VST: added support for sample rate and buffer size changes
73 - VST: close editor (Fantasia) when the VST is removed
74
75 * MIDI driver:
76 - added JACK MIDI driver
77 - dispatch bank select as ordinary CC as well, the user might seriously
78 want to (mis)use it for some purpose ("fixed" in all current MIDI
79 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
80 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
81 CoreMidi or AU
82 - fixed mingw-w64 compilation error in MME driver
83
84 * instruments database:
85 - avoid time consuming samples scanning when adding instruments
86 to the instruments database
87 - added support for handling lost files in the instruments database
88 - Implemented option for adding instruments in separate directories
89 in the instruments database
90 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
91
92 * Gigasampler format engine:
93 - fixed a memory leak that could happen when a channel was deleted
94 while notes were playing
95 - made it possible to load an instrument even if the audio thread
96 isn't running
97 - added partial support for the "Controller Triggered" MIDI rule,
98 enough for piano gigs with pedal noise samples
99 - minor fix: only mark FX sends as being modified if really the
100 respective FX send MIDI controller was used
101 - added support for GM global device volume SysEx message
102 (can be selected at compile time to either apply globally to the
103 whole sampler [default] or only to the sampler channels that are
104 connected to the respective MIDI input port the SysEx message arrived
105 on)
106 - bugfix: notes triggered at position 0 in the audio buffer were
107 sometimes wrongly killed in the same buffer, causing no sound to
108 be played
109 - added support for chromatic / drumkit mode Roland GS Sysex message
110 which is usally used to switch a part between chromatic sounds and
111 drumkit sounds (as opposed to their common default setting of MIDI
112 part 10 being a drumkit part and all other ones chromatic parts), in
113 LS however one can switch between the first 16 MIDI instrument maps
114 defined for the sampler
115 - made it possible to create multiple sample channels even if the
116 audio thread isn't running
117 - fixed crash when removing channel with active voices (#116)
118 - bugfix: on sample reference changes (instrument editor), only
119 un-cache the respective sample if it's really not used by any
120 sampler engine anymore
121 - re-cache samples in case they were changed by an instrument editor,
122 e.g. when a sample was added while playing (#82)
123 - fixed hanging notes which occured when note-off event had the exact
124 same time stamp as the voice's note-on event and occured both in the
125 same audio fragment cycle (fixes bug #112)
126 - added support for the "fine tune" and "pitch bend range"
127 instrument-level gig parameters
128 - fixed minor artifacts in pitch bend handling
129 - added support for GS Reset SysEx message
130 - allow gig files to use unlimited downward pitch shifting
131 - added a limit check for upward pitch shifting
132
133 * LSCP server:
134 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
135 react on MIDI data arriving on certain sampler channels (so far only
136 Note-On and Note-Off events are sent via this LSCP event)
137 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
138 react on MIDI data arriving on certain MIDI input devices (so far only
139 Note-On and Note-Off events are sent via this LSCP event)
140 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
141 SET DB_INSTRUMENT FILE_PATH
142 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
143 frontends to send MIDI messages to specific sampler channel
144 - added two additional fields to GET FILE INSTRUMENT INFO command -
145 KEY_BINDINGS and KEYSWITCH_BINDINGS
146 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
147 was incorrect
148 - Optimized the retrieval of the MIDI instrument mappings
149 - added new LSCP command "SET VOICES" to globally alter the maximum
150 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
151 be triggered respectively
152 - added new LSCP command "SET STREAMS" to globally alter the maximum
153 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
154 which will be triggered respectively
155 - bugfix: retry if "select" returns EINTR (this fixes a crash when
156 a gigedit file dialog is opened)
157 - close all connections when LSCPServer is deleted
158 - hard close of all sockets on exit
159
160 * Bug fixes:
161 - fixed a crash which occurs when removing a sampler channel waiting
162 to start instrument loading after another channel
163 - fixed a crash which occurs when removing a sampler channel with
164 instrument loading in progress (bug #113)
165 - fixed termination caused by uncaught exception when adding MIDI
166 instrument with PERSISTENT load mode
167 - fixed possible iterator invalidations when resetting the sampler
168 - fixed memory leaks when issuing the following LSCP commands:
169 GET AUDIO_OUTPUT_DRIVER INFO
170 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
171 GET MIDI_INPUT_DRIVER INFO
172 GET MIDI_INPUT_DRIVER_PARAMETER INFO
173 - fixed possible compilation error when sqlite is not present
174 - fixed orphaned pointers when setting maximum voices limit (bug #118)
175 - fixed crash when changing the audio output device of a sampler
176 channel with loaded instrument and start playing notes
177 - fixed endless loop in Engine::SuspendAll() (bug #120)
178 - fixed a low-level atomic load function that was broken on 64-bit
179 PowerPC, which probably could cause crashes on that platform
180 - fixed a memory management error which could cause a crash when a
181 plugin was unloaded
182
183
184 Version 0.5.1 (6 December 2007)
185
186 * packaging changes:
187 - added autoconf checks for pthread library
188 - added autoconf check for pthread bug found on certain NPTL-enabled
189 glibc versions (see Gentoo bug report #194076)
190 - added autoconf checks for MS Windows
191
192 * general changes:
193 - bugfix: the thread used by an editor plugin didn't die when the
194 editor closed
195 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
196 out all the space. operator--() did not apply size_mask after
197 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
198 order to avoid problems with the _NonVolatileReader functions.
199 - bugfix: Stream.h: added a missing divide by BytesPerSample in
200 GetWriteSpace(). Since this function is currently only used in
201 the stream's qsort() compare function, it didn't trigger any
202 bugs.
203 - Resampler.h, Synthesizer.h: cubic interpolation now works in
204 24bit mode too. Faster method to read 24bit words on little
205 endian machines (x86): replaced 3 byte reads + shifts with a 1
206 unaligned 32bit read and shift
207 - experimental support for MS Windows (MIDI input via MME, AUDIO
208 output via ASIO)
209 - made handling of SIGINT signal (Ctrl-C) a bit more robust
210 - support for monitoring the total number of active disk streams
211 (new LSCP commands: GET TOTAL_STREAM_COUNT,
212 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
213
214 * AUDIO driver:
215 - added Windows ASIO low latency audio driver
216
217 * MIDI driver:
218 - added MME Windows MIDI driver
219
220 * LSCP server:
221 - added support for Windows style path / filenames, however with
222 forward slash path separators instead of backslash
223 (i.e. "C:/foo/bar.gig")
224 - allow naughty liblscp to send non-string device parameters within
225 apostrophes as well
226 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
227 "LIST FILE INSTRUMENTS <file>" and
228 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
229 about an arbitrary instrument file on the system where the sampler is
230 running on
231
232 Version 0.5.0 (15 October 2007)
233
234 * packaging changes:
235 - config.h is not going to be installed along with liblinuxsampler's
236 API header files anymore
237 - only the API relevant header (and source) files will be exported to
238 the Doxygen API documentation (explicitly listed in Doxyfile.in)
239 - added completely new XCode project files for Mac OSX which is now
240 capable to execute our autoconf environment, thus no need anymore
241 to maintain the compile time configuration file (osx/version.h) for
242 OSX manually (patch by Toshi Nagata)
243 - fixed buggy boolean --enable-foo / --disable-foo configure script
244 parameters
245 - global.h now only covers global definitions that are needed for the
246 C++ API header files, all implementation internal global definitions
247 are now in global_private.h
248 - atomic.h is not exposed to the C++ API anymore
249 - no need to include config.h anymore for using LS's API header files
250 - fixed warnings in API doc generation
251
252 * general changes:
253 - replaced the old, confusing MIDI program change mechanism by a
254 flexible MIDI instrument mapper which allows to map arbitrary
255 (MIDI bank, MIDI program) pairs with arbitrary
256 (engine type, instrument file, file index) triplets which will be
257 loaded on the respective channel when such MIDI program change
258 messages arrive, beside that, each entry allows to define a life-time
259 strategy for the instrument, so the user can define whether the
260 instrument should i.e. be permanently loaded (to be able to switch
261 quickly among sounds) or i.e. loaded just on demand when the
262 respective program change arrives (to safe RAM space), as well as a
263 global volume factor for each entry, so the user can adjust the volume
264 dynamic of his mapped instrument collection without having to modify
265 the instrument files, also one can manage arbitrary amount of such
266 MIDI instrument maps and assign each sampler channel individually
267 a certain map, so that i.e. separation of normal instruments and
268 drumkits is possible
269 - new notification events for tracking changes to audio/MIDI devices,
270 MIDI instrument maps, MIDI instruments, FX sends, global volume.
271 - sampler was limited to load max. 200 instruments in the background
272 due to a constant size RingBuffer FIFO which is now replaced by a
273 dynamic (unlimited) size std::list FIFO
274 - added FX sends, these allow to route audio signals to arbitrary audio
275 output channels for being processed by external effect processors
276 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
277 controllers
278 - global (sampler wide) volume can now be controlled at runtime
279 - Implemented new, improved notification system
280 - fixed compilation errors regarding OSX
281 (patch by Toshi Nagata)
282 - implemented instruments database
283 - added support for escape sequences to the instruments database
284 - added highly experimental support for on-the-fly instrument editing
285 within the sampler's process (by using instrument editor plugins),
286 you'll notice the new "Registered instrument editors:" message on
287 startup, added a new LSCP command:
288 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
289 to spawn a matching instrument editor for the instrument on the
290 given sampler channel, the plugin path can be overridden at compile
291 time with ./configure --enable-plugin-dir=/some/dir
292 - added experimental code for synchronizing instrument editors hosted
293 in the sampler's process to safely edit instruments while playing
294 without a crash (hopefully) by either suspending single regions
295 wherever possible or if unavoidable whole engine(s)
296 - fixed several issues in fundamental "Thread" class: set scheduling
297 policy and priority on thread level, set a minimum stack size for
298 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
299 threads simply inherited properties of starting thread instead of
300 setting their own policy and priority
301 - minor fix in our automatic stack trace mechanism on crashes, the
302 main process did not wait for the stack trace process to finish
303 its output
304 - fixed some minor memory leaks
305 - reenabled assembly features support, at the moment only for
306 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
307 - minor assembly fix in x86 features detection (don't use the PIC
308 register, to avoid relocations in the text segment at runtime)
309 - POSIX callback functions of Thread.h are hidden
310
311 * MIDI driver:
312 - dispatch bank select (MSB and LSB) messages
313
314 * audio driver:
315 - the ALSA audio output driver parameters now reflect the correct
316 parameter value ranges for the respective selected sound card
317 (patch by Till Wimmer, a bit fixed and extended)
318
319 * Gigasampler format engine:
320 - if a filter is used and EG2 finishes before EG1, let the voice
321 die when EG2 has finished (this fixes a problem with clicks and
322 voice starvation for some gigs)
323 - playback is no longer disabled during instrument loading
324 - all notes playing on a channel that changes its instrument keep
325 playing with the old instrument until they get a note off
326 command
327 - EG fix: a release value of zero could cause noises or crash
328 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
329 - EG fine tuning: when attack is zero the EG starts at a level
330 above max sustain level, which means that there is a decay phase
331 even if sustain is 100%
332 - more EG fixes: the level could sometimes go below zero and cause
333 noises or crashes
334 - minor fix of EGDecay (patch by Toshi Nagata)
335 - fixed compiler error when --enable-override-filter-type was
336 supplied to the configure script (fixes #46)
337 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
338 instead of a fix value
339 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
340 127 (solo mode) only kill voices if the respective mode really
341 changed
342
343 * LSCP server:
344 - fixed compile time error for old Bison versions
345 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
346 - parser now supports extended ASCII character set
347 (up to ASCII code 255, i.e. includes now umlauts and accents)
348 - filename arguments in LSCP commands now allow to use escape
349 sequences, that is directly literal as one of: \', \", \\, \n, \r,
350 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
351 code value like \xf2) (fixes bug #24)
352 - the following LSCP commands now also support escape sequences for at
353 least one of their text-based parameters (i.e. name, description):
354 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
355 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
356 "SET DB_INSTRUMENT_DIRECTORY NAME",
357 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
358 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
359 "FIND DB_INSTRUMENT_DIRECTORIES"
360 - returns verbose syntax errors (line and column where syntax error
361 occured, the unexpected character and the actually expected, possible
362 character(s), the latter only if less than 5 possibilities)
363 - made sure that LSCP syntax is not affected by gigedit locale
364 settings
365 - bugfix regarding strings parameter lists: all comma separated lists
366 of strings were treated as being one string containing commas
367 (fixes #57)
368
369 * Bug fixes:
370 - fixed crash occurring on certain LSCP scripts (Bug 39)
371 - another thread safety fix for lscp "load engine" and "set
372 channel audio output device"
373 - fixed a crash which occurs when reassigning the same engine
374 on a sampler channel with connected MIDI device
375 - fixed a crash which occurs when changing the number of ports of a MIDI
376 device connected to a sampler channel to number less then or equal
377 to the index of the port to which the sampler channel is connected.
378 - The previous bindings were not been disconnected when altering
379 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
380 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
381 - The active stream/voice count statistic was incorrect.
382 - notification events were not been sent for some sampler
383 channel changes
384 - added default min and max values to restrict the number of allowed
385 audio output channels and MIDI input ports
386 - the connection to the PCM interface is now closed when destroying
387 an audio output device
388 - files with slash in their path or filename could not be loaded
389
390 * test cases:
391 - updated and fixed (haven't been touched in a while)
392
393 Version 0.4.0 (24 November 2006)
394
395 * packaging changes:
396 - changed deprecated copyright attribute to license; added ldconfig
397 to post-(un)install steps; added devel package for liblinuxsampler;
398 to linuxsampler.spec (RPM)
399 - install necessary development header files for allowing 3rd party
400 applications to link against liblinuxsampler
401 - liblinuxsampler's API documentation can be generated with 'make docs'
402 (Doxygen required)
403 - added benchmark to automatically detect the best triangle LFO
404 implementation (currently either an integer math solution or a
405 di-harmonic approximation), automatic detection can be overriden
406 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
407 configure script argument though (mandatory for cross-compilation)
408 - do not automatically pick optimized gcc flags if the user already
409 provided some on his own (as CXXFLAGS)
410 - added compile time option to disable processing of All-Notes-Off MIDI
411 messages
412 - added compile time options to allow disabling the various audio and
413 MIDI drivers
414 - fixed automatic GCC CPU switch detection on PPC
415 (patch by Ebrahim Mayat)
416
417 * Gigasampler format engine:
418 - extensive synthesis optimization
419 (reimplementation of EGs and LFO(s), removed synthesis parameter
420 prerendering and the synthesis parameter matrix in general, splitting
421 each audio fragment into subfragments now where each subfragment uses
422 constant pitch and filter coefficients. The volume coefficient is
423 linearly interpolated inside a subfragment, unless
424 --disable-interpolate-volume is set.)
425 - fine tuning of the EG modulation parameters
426 - improved filter cutoff calculation by adding support for the
427 following gig parameters: Cutoff freq (used when no cutoff
428 controller is defined), Control invert, Minimum cutoff, Velocity
429 curve and Velocity range. The keyboard tracking now scales
430 cutoff frequency instead of resonance.
431 - added support for gig parameter Resonance.
432 - fixed bug in sysex handling (patch by Juan Linietsky)
433 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
434 which can be overridden with --enable-global-attenuation
435 - EG fixes: made the length of "attack hold" stage more
436 accurate. Release stage can now start before attack stage
437 ends. Cancel release didn't work when sustain was zero. Attack
438 time now has a minimal value to prevent clicks.
439 - fixed pitch changes larger than one octave
440 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
441 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
442 all modes can be altered via standard GM messages, that is CC5 for
443 altering portamento time, CC65 for enabling / disabling portamento
444 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
445 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
446 parameter) and crossfade
447 - added support for the "attenuation controller threshold" gig
448 parameter
449 - added smoothing of volume changes caused by control change
450 messages
451 - sample loop parameters are now taken from the DimensionRegion
452 instead of the wave chunk
453 - fixed keyswitching for v3 gigs with a number of keyswitch splits
454 not equal to a power of two
455 - reimplementation of the filter algorithm. The new filter is more
456 accurate and supports all gig filter types, including bandreject
457 and lowpass turbo.
458 - real support for 24 bit samples - samples are not truncated to
459 16 bits anymore
460 - support for aftertouch (channel pressure, not polyphonic
461 aftertouch)
462 - LFO1 behaviour fixed (dampening from max volume instead of
463 amplifying from 0)
464
465 * LSCP server:
466 - fixed application exit on broken pipe error (fixes bug #20)
467 - fixed the notification messages delay due to lack of
468 network activity (fixes bug #26)
469 - fixed parser bug which occured on space(s) within device parameters
470 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
471
472 * audio driver:
473 - added aRts audio output driver (by no means RT safe)
474
475 * MIDI driver:
476 - fixed legacy sysex code which caused dispatching of MIDI SysEx
477 messages several times instead of once
478 - API extension for MIDI drivers which already supply exact time stamps
479 for events (i.e. for offline rendering based MIDI drivers)
480 - added checks for bad MIDI data
481
482 * linuxsampler application:
483 - show available sampler engine types on startup
484
485 * general changes:
486 - support for muting sampler channels and solo mode of the same, two new
487 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
488 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
489 introduced for this, the behavior is the same like on a mixer console
490 (patch by Grigor Iliev, a bit adjusted). Also added configure option
491 --enable-process-muted-channels which can be used to enable the
492 processing of muted channels.
493 - support for sostenuto pedal
494 - support for monitoring the total number of active voices
495 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
496 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
497 - fixed some memory management errors
498 - fixed some concurrency problems that could lead to crashes when
499 LSCP commands were executed
500 - fixed crash when instrument loading failed previously on the same
501 sampler channel (fixes bug #36)
502
503 Version 0.3.3 (15 July 2005)
504
505 * packaging changes:
506 - fixed compilation with gcc 4.0
507
508 * Gigasampler format engine:
509 - LFO preprocessing was performed even though the respective LFO was
510 disabled by the instrument patch (minor efficiency fix)
511 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
512 for volume ramp downs in the same fragment (needed for current voice
513 stealing implementation) then simply inform the user with a warning
514 about possible click sounds and reduce the volume ramp down
515 appropriately instead of cancelling the audio device connection
516
517 Version 0.3.2 (24 June 2005)
518
519 * packaging changes:
520 - updated autotools build files to compile on OS X
521 (conditional compilation of CoreMIDI and MidiShare drivers)
522 - hand-crafted assembly optimization code can be disabled with
523 './configure --disable-asm' (definitely not recommended)
524 - fixed 'make dist' rule to include all necessary files
525 - require automake (>= 1.5) for 'make -f Makefile.cvs'
526 (due to 'dist-bzip2' automake option)
527
528 * Gigasampler format engine:
529 - support for the gig parameters for "release velocity response" curves
530 - fine tuning of the EGADSR envelope
531 - volume of release triggered samples now depends on note-on velocity,
532 note length and gig parameter "release trigger decay" instead of
533 note-off velocity.
534 - revised voice stealing
535 (fixes crash and endless loop caused by voice stealing)
536 - don't reset scale tuning on instrument or audio output device change
537 - handle key group conflicts right at the beginning of each fragment
538 instead of when the respective voice is actually launched
539 (fixes undefined behavior if stolen voices belonged to a key group -
540 this case was followed by a "killed voice survived" error message)
541 - fixed minor issue with null/silence samples
542 (those stole voices even though they don't need a voice at all which
543 resulted in "voice stealing didn't work out" messages)
544 - don't reset volume, pan, pitch and MIDI controller values on
545 instrument or audio output device change
546
547 * LSCP server:
548 - fixed some crashes (patch by Grigor Iliev, fixes #19)
549 - fixed LSCP event "CHANNEL_INFO" notification
550 (e.g. did not notify on volume changes or MIDI program change events)
551
552 * linuxsampler application:
553 - added command line parameters --lscp-addr and --lscp-port to override
554 default IP address and port of LSCP server
555
556 Version 0.3.1 (24 May 2005)
557
558 * initial release
