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 - Windows: look for editor plugins and Fantasia using base
16 directory of liblinuxsampler dll
17 - configure script fix: removed unconditional use of SSE
18
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
57
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
77 - VST: avoid opening Fantasia more than once for each VST instance
78 - VST: export main function as "main" on Linux too (fix for
79 energyXT)
80
81 * MIDI driver:
82 - added JACK MIDI driver
83 - dispatch bank select as ordinary CC as well, the user might seriously
84 want to (mis)use it for some purpose ("fixed" in all current MIDI
85 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
86 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
87 CoreMidi or AU
88 - fixed mingw-w64 compilation error in MME driver
89
90 * instruments database:
91 - avoid time consuming samples scanning when adding instruments
92 to the instruments database
93 - added support for handling lost files in the instruments database
94 - Implemented option for adding instruments in separate directories
95 in the instruments database
96 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
97 - work-around for missing fnmatch function on Windows to make
98 instrument database compilable
99
100 * Gigasampler format engine:
101 - fixed a memory leak that could happen when a channel was deleted
102 while notes were playing
103 - made it possible to load an instrument even if the audio thread
104 isn't running
105 - added partial support for the "Controller Triggered" MIDI rule,
106 enough for piano gigs with pedal noise samples
107 - minor fix: only mark FX sends as being modified if really the
108 respective FX send MIDI controller was used
109 - added support for GM global device volume SysEx message
110 (can be selected at compile time to either apply globally to the
111 whole sampler [default] or only to the sampler channels that are
112 connected to the respective MIDI input port the SysEx message arrived
113 on)
114 - bugfix: notes triggered at position 0 in the audio buffer were
115 sometimes wrongly killed in the same buffer, causing no sound to
116 be played
117 - added support for chromatic / drumkit mode Roland GS Sysex message
118 which is usally used to switch a part between chromatic sounds and
119 drumkit sounds (as opposed to their common default setting of MIDI
120 part 10 being a drumkit part and all other ones chromatic parts), in
121 LS however one can switch between the first 16 MIDI instrument maps
122 defined for the sampler
123 - made it possible to create multiple sample channels even if the
124 audio thread isn't running
125 - fixed crash when removing channel with active voices (#116)
126 - bugfix: on sample reference changes (instrument editor), only
127 un-cache the respective sample if it's really not used by any
128 sampler engine anymore
129 - re-cache samples in case they were changed by an instrument editor,
130 e.g. when a sample was added while playing (#82)
131 - fixed hanging notes which occured when note-off event had the exact
132 same time stamp as the voice's note-on event and occured both in the
133 same audio fragment cycle (fixes bug #112)
134 - added support for the "fine tune" and "pitch bend range"
135 instrument-level gig parameters
136 - fixed minor artifacts in pitch bend handling
137 - added support for GS Reset SysEx message
138 - allow gig files to use unlimited downward pitch shifting
139 - added a limit check for upward pitch shifting
140 - bugfix: sometimes, when playing a note twice fast, the second
141 note was silent
142
143 * LSCP server:
144 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
145 react on MIDI data arriving on certain sampler channels (so far only
146 Note-On and Note-Off events are sent via this LSCP event)
147 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
148 react on MIDI data arriving on certain MIDI input devices (so far only
149 Note-On and Note-Off events are sent via this LSCP event)
150 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
151 SET DB_INSTRUMENT FILE_PATH
152 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
153 frontends to send MIDI messages to specific sampler channel
154 - added two additional fields to GET FILE INSTRUMENT INFO command -
155 KEY_BINDINGS and KEYSWITCH_BINDINGS
156 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
157 was incorrect
158 - Optimized the retrieval of the MIDI instrument mappings
159 - added new LSCP command "SET VOICES" to globally alter the maximum
160 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
161 be triggered respectively
162 - added new LSCP command "SET STREAMS" to globally alter the maximum
163 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
164 which will be triggered respectively
165 - bugfix: retry if "select" returns EINTR (this fixes a crash when
166 a gigedit file dialog is opened)
167 - close all connections when LSCPServer is deleted
168 - hard close of all sockets on exit
169 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
170 driver
171
172 * Bug fixes:
173 - fixed a crash which occurs when removing a sampler channel waiting
174 to start instrument loading after another channel
175 - fixed a crash which occurs when removing a sampler channel with
176 instrument loading in progress (bug #113)
177 - fixed termination caused by uncaught exception when adding MIDI
178 instrument with PERSISTENT load mode
179 - fixed possible iterator invalidations when resetting the sampler
180 - fixed memory leaks when issuing the following LSCP commands:
181 GET AUDIO_OUTPUT_DRIVER INFO
182 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
183 GET MIDI_INPUT_DRIVER INFO
184 GET MIDI_INPUT_DRIVER_PARAMETER INFO
185 - fixed possible compilation error when sqlite is not present
186 - fixed orphaned pointers when setting maximum voices limit (bug #118)
187 - fixed crash when changing the audio output device of a sampler
188 channel with loaded instrument and start playing notes
189 - fixed endless loop in Engine::SuspendAll() (bug #120)
190 - fixed a low-level atomic load function that was broken on 64-bit
191 PowerPC, which probably could cause crashes on that platform
192 - fixed a memory management error which could cause a crash when a
193 plugin was unloaded
194 - bugfix: two private structs had the same name, which could cause
195 problems if the linker chose the wrong constructor
196
197
198 Version 0.5.1 (6 December 2007)
199
200 * packaging changes:
201 - added autoconf checks for pthread library
202 - added autoconf check for pthread bug found on certain NPTL-enabled
203 glibc versions (see Gentoo bug report #194076)
204 - added autoconf checks for MS Windows
205
206 * general changes:
207 - bugfix: the thread used by an editor plugin didn't die when the
208 editor closed
209 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
210 out all the space. operator--() did not apply size_mask after
211 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
212 order to avoid problems with the _NonVolatileReader functions.
213 - bugfix: Stream.h: added a missing divide by BytesPerSample in
214 GetWriteSpace(). Since this function is currently only used in
215 the stream's qsort() compare function, it didn't trigger any
216 bugs.
217 - Resampler.h, Synthesizer.h: cubic interpolation now works in
218 24bit mode too. Faster method to read 24bit words on little
219 endian machines (x86): replaced 3 byte reads + shifts with a 1
220 unaligned 32bit read and shift
221 - experimental support for MS Windows (MIDI input via MME, AUDIO
222 output via ASIO)
223 - made handling of SIGINT signal (Ctrl-C) a bit more robust
224 - support for monitoring the total number of active disk streams
225 (new LSCP commands: GET TOTAL_STREAM_COUNT,
226 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
227
228 * AUDIO driver:
229 - added Windows ASIO low latency audio driver
230
231 * MIDI driver:
232 - added MME Windows MIDI driver
233
234 * LSCP server:
235 - added support for Windows style path / filenames, however with
236 forward slash path separators instead of backslash
237 (i.e. "C:/foo/bar.gig")
238 - allow naughty liblscp to send non-string device parameters within
239 apostrophes as well
240 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
241 "LIST FILE INSTRUMENTS <file>" and
242 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
243 about an arbitrary instrument file on the system where the sampler is
244 running on
245
246 Version 0.5.0 (15 October 2007)
247
248 * packaging changes:
249 - config.h is not going to be installed along with liblinuxsampler's
250 API header files anymore
251 - only the API relevant header (and source) files will be exported to
252 the Doxygen API documentation (explicitly listed in Doxyfile.in)
253 - added completely new XCode project files for Mac OSX which is now
254 capable to execute our autoconf environment, thus no need anymore
255 to maintain the compile time configuration file (osx/version.h) for
256 OSX manually (patch by Toshi Nagata)
257 - fixed buggy boolean --enable-foo / --disable-foo configure script
258 parameters
259 - global.h now only covers global definitions that are needed for the
260 C++ API header files, all implementation internal global definitions
261 are now in global_private.h
262 - atomic.h is not exposed to the C++ API anymore
263 - no need to include config.h anymore for using LS's API header files
264 - fixed warnings in API doc generation
265
266 * general changes:
267 - replaced the old, confusing MIDI program change mechanism by a
268 flexible MIDI instrument mapper which allows to map arbitrary
269 (MIDI bank, MIDI program) pairs with arbitrary
270 (engine type, instrument file, file index) triplets which will be
271 loaded on the respective channel when such MIDI program change
272 messages arrive, beside that, each entry allows to define a life-time
273 strategy for the instrument, so the user can define whether the
274 instrument should i.e. be permanently loaded (to be able to switch
275 quickly among sounds) or i.e. loaded just on demand when the
276 respective program change arrives (to safe RAM space), as well as a
277 global volume factor for each entry, so the user can adjust the volume
278 dynamic of his mapped instrument collection without having to modify
279 the instrument files, also one can manage arbitrary amount of such
280 MIDI instrument maps and assign each sampler channel individually
281 a certain map, so that i.e. separation of normal instruments and
282 drumkits is possible
283 - new notification events for tracking changes to audio/MIDI devices,
284 MIDI instrument maps, MIDI instruments, FX sends, global volume.
285 - sampler was limited to load max. 200 instruments in the background
286 due to a constant size RingBuffer FIFO which is now replaced by a
287 dynamic (unlimited) size std::list FIFO
288 - added FX sends, these allow to route audio signals to arbitrary audio
289 output channels for being processed by external effect processors
290 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
291 controllers
292 - global (sampler wide) volume can now be controlled at runtime
293 - Implemented new, improved notification system
294 - fixed compilation errors regarding OSX
295 (patch by Toshi Nagata)
296 - implemented instruments database
297 - added support for escape sequences to the instruments database
298 - added highly experimental support for on-the-fly instrument editing
299 within the sampler's process (by using instrument editor plugins),
300 you'll notice the new "Registered instrument editors:" message on
301 startup, added a new LSCP command:
302 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
303 to spawn a matching instrument editor for the instrument on the
304 given sampler channel, the plugin path can be overridden at compile
305 time with ./configure --enable-plugin-dir=/some/dir
306 - added experimental code for synchronizing instrument editors hosted
307 in the sampler's process to safely edit instruments while playing
308 without a crash (hopefully) by either suspending single regions
309 wherever possible or if unavoidable whole engine(s)
310 - fixed several issues in fundamental "Thread" class: set scheduling
311 policy and priority on thread level, set a minimum stack size for
312 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
313 threads simply inherited properties of starting thread instead of
314 setting their own policy and priority
315 - minor fix in our automatic stack trace mechanism on crashes, the
316 main process did not wait for the stack trace process to finish
317 its output
318 - fixed some minor memory leaks
319 - reenabled assembly features support, at the moment only for
320 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
321 - minor assembly fix in x86 features detection (don't use the PIC
322 register, to avoid relocations in the text segment at runtime)
323 - POSIX callback functions of Thread.h are hidden
324
325 * MIDI driver:
326 - dispatch bank select (MSB and LSB) messages
327
328 * audio driver:
329 - the ALSA audio output driver parameters now reflect the correct
330 parameter value ranges for the respective selected sound card
331 (patch by Till Wimmer, a bit fixed and extended)
332
333 * Gigasampler format engine:
334 - if a filter is used and EG2 finishes before EG1, let the voice
335 die when EG2 has finished (this fixes a problem with clicks and
336 voice starvation for some gigs)
337 - playback is no longer disabled during instrument loading
338 - all notes playing on a channel that changes its instrument keep
339 playing with the old instrument until they get a note off
340 command
341 - EG fix: a release value of zero could cause noises or crash
342 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
343 - EG fine tuning: when attack is zero the EG starts at a level
344 above max sustain level, which means that there is a decay phase
345 even if sustain is 100%
346 - more EG fixes: the level could sometimes go below zero and cause
347 noises or crashes
348 - minor fix of EGDecay (patch by Toshi Nagata)
349 - fixed compiler error when --enable-override-filter-type was
350 supplied to the configure script (fixes #46)
351 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
352 instead of a fix value
353 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
354 127 (solo mode) only kill voices if the respective mode really
355 changed
356
357 * LSCP server:
358 - fixed compile time error for old Bison versions
359 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
360 - parser now supports extended ASCII character set
361 (up to ASCII code 255, i.e. includes now umlauts and accents)
362 - filename arguments in LSCP commands now allow to use escape
363 sequences, that is directly literal as one of: \', \", \\, \n, \r,
364 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
365 code value like \xf2) (fixes bug #24)
366 - the following LSCP commands now also support escape sequences for at
367 least one of their text-based parameters (i.e. name, description):
368 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
369 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
370 "SET DB_INSTRUMENT_DIRECTORY NAME",
371 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
372 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
373 "FIND DB_INSTRUMENT_DIRECTORIES"
374 - returns verbose syntax errors (line and column where syntax error
375 occured, the unexpected character and the actually expected, possible
376 character(s), the latter only if less than 5 possibilities)
377 - made sure that LSCP syntax is not affected by gigedit locale
378 settings
379 - bugfix regarding strings parameter lists: all comma separated lists
380 of strings were treated as being one string containing commas
381 (fixes #57)
382
383 * Bug fixes:
384 - fixed crash occurring on certain LSCP scripts (Bug 39)
385 - another thread safety fix for lscp "load engine" and "set
386 channel audio output device"
387 - fixed a crash which occurs when reassigning the same engine
388 on a sampler channel with connected MIDI device
389 - fixed a crash which occurs when changing the number of ports of a MIDI
390 device connected to a sampler channel to number less then or equal
391 to the index of the port to which the sampler channel is connected.
392 - The previous bindings were not been disconnected when altering
393 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
394 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
395 - The active stream/voice count statistic was incorrect.
396 - notification events were not been sent for some sampler
397 channel changes
398 - added default min and max values to restrict the number of allowed
399 audio output channels and MIDI input ports
400 - the connection to the PCM interface is now closed when destroying
401 an audio output device
402 - files with slash in their path or filename could not be loaded
403
404 * test cases:
405 - updated and fixed (haven't been touched in a while)
406
407 Version 0.4.0 (24 November 2006)
408
409 * packaging changes:
410 - changed deprecated copyright attribute to license; added ldconfig
411 to post-(un)install steps; added devel package for liblinuxsampler;
412 to linuxsampler.spec (RPM)
413 - install necessary development header files for allowing 3rd party
414 applications to link against liblinuxsampler
415 - liblinuxsampler's API documentation can be generated with 'make docs'
416 (Doxygen required)
417 - added benchmark to automatically detect the best triangle LFO
418 implementation (currently either an integer math solution or a
419 di-harmonic approximation), automatic detection can be overriden
420 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
421 configure script argument though (mandatory for cross-compilation)
422 - do not automatically pick optimized gcc flags if the user already
423 provided some on his own (as CXXFLAGS)
424 - added compile time option to disable processing of All-Notes-Off MIDI
425 messages
426 - added compile time options to allow disabling the various audio and
427 MIDI drivers
428 - fixed automatic GCC CPU switch detection on PPC
429 (patch by Ebrahim Mayat)
430
431 * Gigasampler format engine:
432 - extensive synthesis optimization
433 (reimplementation of EGs and LFO(s), removed synthesis parameter
434 prerendering and the synthesis parameter matrix in general, splitting
435 each audio fragment into subfragments now where each subfragment uses
436 constant pitch and filter coefficients. The volume coefficient is
437 linearly interpolated inside a subfragment, unless
438 --disable-interpolate-volume is set.)
439 - fine tuning of the EG modulation parameters
440 - improved filter cutoff calculation by adding support for the
441 following gig parameters: Cutoff freq (used when no cutoff
442 controller is defined), Control invert, Minimum cutoff, Velocity
443 curve and Velocity range. The keyboard tracking now scales
444 cutoff frequency instead of resonance.
445 - added support for gig parameter Resonance.
446 - fixed bug in sysex handling (patch by Juan Linietsky)
447 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
448 which can be overridden with --enable-global-attenuation
449 - EG fixes: made the length of "attack hold" stage more
450 accurate. Release stage can now start before attack stage
451 ends. Cancel release didn't work when sustain was zero. Attack
452 time now has a minimal value to prevent clicks.
453 - fixed pitch changes larger than one octave
454 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
455 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
456 all modes can be altered via standard GM messages, that is CC5 for
457 altering portamento time, CC65 for enabling / disabling portamento
458 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
459 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
460 parameter) and crossfade
461 - added support for the "attenuation controller threshold" gig
462 parameter
463 - added smoothing of volume changes caused by control change
464 messages
465 - sample loop parameters are now taken from the DimensionRegion
466 instead of the wave chunk
467 - fixed keyswitching for v3 gigs with a number of keyswitch splits
468 not equal to a power of two
469 - reimplementation of the filter algorithm. The new filter is more
470 accurate and supports all gig filter types, including bandreject
471 and lowpass turbo.
472 - real support for 24 bit samples - samples are not truncated to
473 16 bits anymore
474 - support for aftertouch (channel pressure, not polyphonic
475 aftertouch)
476 - LFO1 behaviour fixed (dampening from max volume instead of
477 amplifying from 0)
478
479 * LSCP server:
480 - fixed application exit on broken pipe error (fixes bug #20)
481 - fixed the notification messages delay due to lack of
482 network activity (fixes bug #26)
483 - fixed parser bug which occured on space(s) within device parameters
484 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
485
486 * audio driver:
487 - added aRts audio output driver (by no means RT safe)
488
489 * MIDI driver:
490 - fixed legacy sysex code which caused dispatching of MIDI SysEx
491 messages several times instead of once
492 - API extension for MIDI drivers which already supply exact time stamps
493 for events (i.e. for offline rendering based MIDI drivers)
494 - added checks for bad MIDI data
495
496 * linuxsampler application:
497 - show available sampler engine types on startup
498
499 * general changes:
500 - support for muting sampler channels and solo mode of the same, two new
501 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
502 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
503 introduced for this, the behavior is the same like on a mixer console
504 (patch by Grigor Iliev, a bit adjusted). Also added configure option
505 --enable-process-muted-channels which can be used to enable the
506 processing of muted channels.
507 - support for sostenuto pedal
508 - support for monitoring the total number of active voices
509 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
510 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
511 - fixed some memory management errors
512 - fixed some concurrency problems that could lead to crashes when
513 LSCP commands were executed
514 - fixed crash when instrument loading failed previously on the same
515 sampler channel (fixes bug #36)
516
517 Version 0.3.3 (15 July 2005)
518
519 * packaging changes:
520 - fixed compilation with gcc 4.0
521
522 * Gigasampler format engine:
523 - LFO preprocessing was performed even though the respective LFO was
524 disabled by the instrument patch (minor efficiency fix)
525 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
526 for volume ramp downs in the same fragment (needed for current voice
527 stealing implementation) then simply inform the user with a warning
528 about possible click sounds and reduce the volume ramp down
529 appropriately instead of cancelling the audio device connection
530
531 Version 0.3.2 (24 June 2005)
532
533 * packaging changes:
534 - updated autotools build files to compile on OS X
535 (conditional compilation of CoreMIDI and MidiShare drivers)
536 - hand-crafted assembly optimization code can be disabled with
537 './configure --disable-asm' (definitely not recommended)
538 - fixed 'make dist' rule to include all necessary files
539 - require automake (>= 1.5) for 'make -f Makefile.cvs'
540 (due to 'dist-bzip2' automake option)
541
542 * Gigasampler format engine:
543 - support for the gig parameters for "release velocity response" curves
544 - fine tuning of the EGADSR envelope
545 - volume of release triggered samples now depends on note-on velocity,
546 note length and gig parameter "release trigger decay" instead of
547 note-off velocity.
548 - revised voice stealing
549 (fixes crash and endless loop caused by voice stealing)
550 - don't reset scale tuning on instrument or audio output device change
551 - handle key group conflicts right at the beginning of each fragment
552 instead of when the respective voice is actually launched
553 (fixes undefined behavior if stolen voices belonged to a key group -
554 this case was followed by a "killed voice survived" error message)
555 - fixed minor issue with null/silence samples
556 (those stole voices even though they don't need a voice at all which
557 resulted in "voice stealing didn't work out" messages)
558 - don't reset volume, pan, pitch and MIDI controller values on
559 instrument or audio output device change
560
561 * LSCP server:
562 - fixed some crashes (patch by Grigor Iliev, fixes #19)
563 - fixed LSCP event "CHANNEL_INFO" notification
564 (e.g. did not notify on volume changes or MIDI program change events)
565
566 * linuxsampler application:
567 - added command line parameters --lscp-addr and --lscp-port to override
568 default IP address and port of LSCP server
569
570 Version 0.3.1 (24 May 2005)
571
572 * initial release
