* Windows: look for editor plugins and Fantasia using base directory
  of liblinuxsampler dll
* lscp bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
  driver

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
18 * general changes:
19 - bugfix: on some POSIX systems instrument editor plugins refused to
20 load as we used a non-portable Linux specific struct field
21 (fixes bug #70, patch by Ronald Baljeu)
22 - fixed endless loop which occured when loading an instrument editor
23 plugin DLL on Windows systems failed
24 - fixed memory leaks that occurred when liblinuxsampler was unloaded
25 - optimized the SynchronizedConfig class so it doesn't wait
26 unnecessarily long after an update
27 - added support for notifying instrument editors on note-on / note-off
28 events (e.g. to highlight the pressed keys on the virtual keyboard
29 of gigedit)
30 - added support for triggering notes by instrument editors (see above)
31 - be verbose on DLL load errors (on Linux)
32 - fixed di-harmonic triangle LFO implementation (this LFO implementation
33 is only used by very few systems, most pick the int math
34 implementation, which is usually faster)
35 - fixes for audio drivers with varying buffer sizes
36 - experimental support for running LinuxSampler as a DSSI, LV2 and
37 VST plugin
38 - notification events for stream/voice count statistics are now sent
39 only when there are actual changes
40 - added memory ordering constraints to improve stability on
41 multi-core and multi-cpu systems
42 - maximum voices and disk streams can now be altered at runtime
43 - fixed CPU feature detection on x86_64 (maybe fixes #108)
44 - automatic stacktrace mechanism is now turned off by default and can
45 be switched on by command line option "--stacktrace" (the automatic
46 stacktrace mechanism seems to be broken on most systems at the moment)
47 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
48 a pointer to the launched InstrumentEditor object
49 - added optional 3rd party user data parameter for following
50 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
51 InstrumentEditor::Launch(),
52 InstrumentManager::LaunchInstrumentEditor()
53 - theoretical fix: made SynchronizedConfig follow C++0x memory
54 model more strictly
55 - fixes for using large audio device buffers
56
57 * audio driver:
58 - removed the nonsense audio channel constraint (which was hard coded to
59 max. 100 audio channels) for most audio drivers
60 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
61 opposed to the LSCP specs
62 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
63 reflected the wrong value
64 - fixed a memory management bug in ASIO driver
65 - Makefile fix: JACK_CFLAGS wasn't used
66 - JACK: use jack_client_open instead of the deprecated
67 jack_client_new
68 - added (experimental) CoreAudio driver
69 - applied old fixes to the ASIO driver that were included in the
70 previous binary release but accidentally never committed to CVS
71 (fixes #117)
72 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
73 win64)
74 - VST: added support for sample rate and buffer size changes
75 - VST: close editor (Fantasia) when the VST is removed
76
77 * MIDI driver:
78 - added JACK MIDI driver
79 - dispatch bank select as ordinary CC as well, the user might seriously
80 want to (mis)use it for some purpose ("fixed" in all current MIDI
81 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
82 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
83 CoreMidi or AU
84 - fixed mingw-w64 compilation error in MME driver
85
86 * instruments database:
87 - avoid time consuming samples scanning when adding instruments
88 to the instruments database
89 - added support for handling lost files in the instruments database
90 - Implemented option for adding instruments in separate directories
91 in the instruments database
92 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
93
94 * Gigasampler format engine:
95 - fixed a memory leak that could happen when a channel was deleted
96 while notes were playing
97 - made it possible to load an instrument even if the audio thread
98 isn't running
99 - added partial support for the "Controller Triggered" MIDI rule,
100 enough for piano gigs with pedal noise samples
101 - minor fix: only mark FX sends as being modified if really the
102 respective FX send MIDI controller was used
103 - added support for GM global device volume SysEx message
104 (can be selected at compile time to either apply globally to the
105 whole sampler [default] or only to the sampler channels that are
106 connected to the respective MIDI input port the SysEx message arrived
107 on)
108 - bugfix: notes triggered at position 0 in the audio buffer were
109 sometimes wrongly killed in the same buffer, causing no sound to
110 be played
111 - added support for chromatic / drumkit mode Roland GS Sysex message
112 which is usally used to switch a part between chromatic sounds and
113 drumkit sounds (as opposed to their common default setting of MIDI
114 part 10 being a drumkit part and all other ones chromatic parts), in
115 LS however one can switch between the first 16 MIDI instrument maps
116 defined for the sampler
117 - made it possible to create multiple sample channels even if the
118 audio thread isn't running
119 - fixed crash when removing channel with active voices (#116)
120 - bugfix: on sample reference changes (instrument editor), only
121 un-cache the respective sample if it's really not used by any
122 sampler engine anymore
123 - re-cache samples in case they were changed by an instrument editor,
124 e.g. when a sample was added while playing (#82)
125 - fixed hanging notes which occured when note-off event had the exact
126 same time stamp as the voice's note-on event and occured both in the
127 same audio fragment cycle (fixes bug #112)
128 - added support for the "fine tune" and "pitch bend range"
129 instrument-level gig parameters
130 - fixed minor artifacts in pitch bend handling
131 - added support for GS Reset SysEx message
132 - allow gig files to use unlimited downward pitch shifting
133 - added a limit check for upward pitch shifting
134
135 * LSCP server:
136 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
137 react on MIDI data arriving on certain sampler channels (so far only
138 Note-On and Note-Off events are sent via this LSCP event)
139 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
140 react on MIDI data arriving on certain MIDI input devices (so far only
141 Note-On and Note-Off events are sent via this LSCP event)
142 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
143 SET DB_INSTRUMENT FILE_PATH
144 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
145 frontends to send MIDI messages to specific sampler channel
146 - added two additional fields to GET FILE INSTRUMENT INFO command -
147 KEY_BINDINGS and KEYSWITCH_BINDINGS
148 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
149 was incorrect
150 - Optimized the retrieval of the MIDI instrument mappings
151 - added new LSCP command "SET VOICES" to globally alter the maximum
152 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
153 be triggered respectively
154 - added new LSCP command "SET STREAMS" to globally alter the maximum
155 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
156 which will be triggered respectively
157 - bugfix: retry if "select" returns EINTR (this fixes a crash when
158 a gigedit file dialog is opened)
159 - close all connections when LSCPServer is deleted
160 - hard close of all sockets on exit
161 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
162 driver
163
164 * Bug fixes:
165 - fixed a crash which occurs when removing a sampler channel waiting
166 to start instrument loading after another channel
167 - fixed a crash which occurs when removing a sampler channel with
168 instrument loading in progress (bug #113)
169 - fixed termination caused by uncaught exception when adding MIDI
170 instrument with PERSISTENT load mode
171 - fixed possible iterator invalidations when resetting the sampler
172 - fixed memory leaks when issuing the following LSCP commands:
173 GET AUDIO_OUTPUT_DRIVER INFO
174 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
175 GET MIDI_INPUT_DRIVER INFO
176 GET MIDI_INPUT_DRIVER_PARAMETER INFO
177 - fixed possible compilation error when sqlite is not present
178 - fixed orphaned pointers when setting maximum voices limit (bug #118)
179 - fixed crash when changing the audio output device of a sampler
180 channel with loaded instrument and start playing notes
181 - fixed endless loop in Engine::SuspendAll() (bug #120)
182 - fixed a low-level atomic load function that was broken on 64-bit
183 PowerPC, which probably could cause crashes on that platform
184 - fixed a memory management error which could cause a crash when a
185 plugin was unloaded
186 - bugfix: two private structs had the same name, which could cause
187 problems if the linker chose the wrong constructor
188
189
190 Version 0.5.1 (6 December 2007)
191
192 * packaging changes:
193 - added autoconf checks for pthread library
194 - added autoconf check for pthread bug found on certain NPTL-enabled
195 glibc versions (see Gentoo bug report #194076)
196 - added autoconf checks for MS Windows
197
198 * general changes:
199 - bugfix: the thread used by an editor plugin didn't die when the
200 editor closed
201 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
202 out all the space. operator--() did not apply size_mask after
203 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
204 order to avoid problems with the _NonVolatileReader functions.
205 - bugfix: Stream.h: added a missing divide by BytesPerSample in
206 GetWriteSpace(). Since this function is currently only used in
207 the stream's qsort() compare function, it didn't trigger any
208 bugs.
209 - Resampler.h, Synthesizer.h: cubic interpolation now works in
210 24bit mode too. Faster method to read 24bit words on little
211 endian machines (x86): replaced 3 byte reads + shifts with a 1
212 unaligned 32bit read and shift
213 - experimental support for MS Windows (MIDI input via MME, AUDIO
214 output via ASIO)
215 - made handling of SIGINT signal (Ctrl-C) a bit more robust
216 - support for monitoring the total number of active disk streams
217 (new LSCP commands: GET TOTAL_STREAM_COUNT,
218 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
219
220 * AUDIO driver:
221 - added Windows ASIO low latency audio driver
222
223 * MIDI driver:
224 - added MME Windows MIDI driver
225
226 * LSCP server:
227 - added support for Windows style path / filenames, however with
228 forward slash path separators instead of backslash
229 (i.e. "C:/foo/bar.gig")
230 - allow naughty liblscp to send non-string device parameters within
231 apostrophes as well
232 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
233 "LIST FILE INSTRUMENTS <file>" and
234 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
235 about an arbitrary instrument file on the system where the sampler is
236 running on
237
238 Version 0.5.0 (15 October 2007)
239
240 * packaging changes:
241 - config.h is not going to be installed along with liblinuxsampler's
242 API header files anymore
243 - only the API relevant header (and source) files will be exported to
244 the Doxygen API documentation (explicitly listed in Doxyfile.in)
245 - added completely new XCode project files for Mac OSX which is now
246 capable to execute our autoconf environment, thus no need anymore
247 to maintain the compile time configuration file (osx/version.h) for
248 OSX manually (patch by Toshi Nagata)
249 - fixed buggy boolean --enable-foo / --disable-foo configure script
250 parameters
251 - global.h now only covers global definitions that are needed for the
252 C++ API header files, all implementation internal global definitions
253 are now in global_private.h
254 - atomic.h is not exposed to the C++ API anymore
255 - no need to include config.h anymore for using LS's API header files
256 - fixed warnings in API doc generation
257
258 * general changes:
259 - replaced the old, confusing MIDI program change mechanism by a
260 flexible MIDI instrument mapper which allows to map arbitrary
261 (MIDI bank, MIDI program) pairs with arbitrary
262 (engine type, instrument file, file index) triplets which will be
263 loaded on the respective channel when such MIDI program change
264 messages arrive, beside that, each entry allows to define a life-time
265 strategy for the instrument, so the user can define whether the
266 instrument should i.e. be permanently loaded (to be able to switch
267 quickly among sounds) or i.e. loaded just on demand when the
268 respective program change arrives (to safe RAM space), as well as a
269 global volume factor for each entry, so the user can adjust the volume
270 dynamic of his mapped instrument collection without having to modify
271 the instrument files, also one can manage arbitrary amount of such
272 MIDI instrument maps and assign each sampler channel individually
273 a certain map, so that i.e. separation of normal instruments and
274 drumkits is possible
275 - new notification events for tracking changes to audio/MIDI devices,
276 MIDI instrument maps, MIDI instruments, FX sends, global volume.
277 - sampler was limited to load max. 200 instruments in the background
278 due to a constant size RingBuffer FIFO which is now replaced by a
279 dynamic (unlimited) size std::list FIFO
280 - added FX sends, these allow to route audio signals to arbitrary audio
281 output channels for being processed by external effect processors
282 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
283 controllers
284 - global (sampler wide) volume can now be controlled at runtime
285 - Implemented new, improved notification system
286 - fixed compilation errors regarding OSX
287 (patch by Toshi Nagata)
288 - implemented instruments database
289 - added support for escape sequences to the instruments database
290 - added highly experimental support for on-the-fly instrument editing
291 within the sampler's process (by using instrument editor plugins),
292 you'll notice the new "Registered instrument editors:" message on
293 startup, added a new LSCP command:
294 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
295 to spawn a matching instrument editor for the instrument on the
296 given sampler channel, the plugin path can be overridden at compile
297 time with ./configure --enable-plugin-dir=/some/dir
298 - added experimental code for synchronizing instrument editors hosted
299 in the sampler's process to safely edit instruments while playing
300 without a crash (hopefully) by either suspending single regions
301 wherever possible or if unavoidable whole engine(s)
302 - fixed several issues in fundamental "Thread" class: set scheduling
303 policy and priority on thread level, set a minimum stack size for
304 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
305 threads simply inherited properties of starting thread instead of
306 setting their own policy and priority
307 - minor fix in our automatic stack trace mechanism on crashes, the
308 main process did not wait for the stack trace process to finish
309 its output
310 - fixed some minor memory leaks
311 - reenabled assembly features support, at the moment only for
312 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
313 - minor assembly fix in x86 features detection (don't use the PIC
314 register, to avoid relocations in the text segment at runtime)
315 - POSIX callback functions of Thread.h are hidden
316
317 * MIDI driver:
318 - dispatch bank select (MSB and LSB) messages
319
320 * audio driver:
321 - the ALSA audio output driver parameters now reflect the correct
322 parameter value ranges for the respective selected sound card
323 (patch by Till Wimmer, a bit fixed and extended)
324
325 * Gigasampler format engine:
326 - if a filter is used and EG2 finishes before EG1, let the voice
327 die when EG2 has finished (this fixes a problem with clicks and
328 voice starvation for some gigs)
329 - playback is no longer disabled during instrument loading
330 - all notes playing on a channel that changes its instrument keep
331 playing with the old instrument until they get a note off
332 command
333 - EG fix: a release value of zero could cause noises or crash
334 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
335 - EG fine tuning: when attack is zero the EG starts at a level
336 above max sustain level, which means that there is a decay phase
337 even if sustain is 100%
338 - more EG fixes: the level could sometimes go below zero and cause
339 noises or crashes
340 - minor fix of EGDecay (patch by Toshi Nagata)
341 - fixed compiler error when --enable-override-filter-type was
342 supplied to the configure script (fixes #46)
343 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
344 instead of a fix value
345 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
346 127 (solo mode) only kill voices if the respective mode really
347 changed
348
349 * LSCP server:
350 - fixed compile time error for old Bison versions
351 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
352 - parser now supports extended ASCII character set
353 (up to ASCII code 255, i.e. includes now umlauts and accents)
354 - filename arguments in LSCP commands now allow to use escape
355 sequences, that is directly literal as one of: \', \", \\, \n, \r,
356 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
357 code value like \xf2) (fixes bug #24)
358 - the following LSCP commands now also support escape sequences for at
359 least one of their text-based parameters (i.e. name, description):
360 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
361 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
362 "SET DB_INSTRUMENT_DIRECTORY NAME",
363 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
364 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
365 "FIND DB_INSTRUMENT_DIRECTORIES"
366 - returns verbose syntax errors (line and column where syntax error
367 occured, the unexpected character and the actually expected, possible
368 character(s), the latter only if less than 5 possibilities)
369 - made sure that LSCP syntax is not affected by gigedit locale
370 settings
371 - bugfix regarding strings parameter lists: all comma separated lists
372 of strings were treated as being one string containing commas
373 (fixes #57)
374
375 * Bug fixes:
376 - fixed crash occurring on certain LSCP scripts (Bug 39)
377 - another thread safety fix for lscp "load engine" and "set
378 channel audio output device"
379 - fixed a crash which occurs when reassigning the same engine
380 on a sampler channel with connected MIDI device
381 - fixed a crash which occurs when changing the number of ports of a MIDI
382 device connected to a sampler channel to number less then or equal
383 to the index of the port to which the sampler channel is connected.
384 - The previous bindings were not been disconnected when altering
385 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
386 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
387 - The active stream/voice count statistic was incorrect.
388 - notification events were not been sent for some sampler
389 channel changes
390 - added default min and max values to restrict the number of allowed
391 audio output channels and MIDI input ports
392 - the connection to the PCM interface is now closed when destroying
393 an audio output device
394 - files with slash in their path or filename could not be loaded
395
396 * test cases:
397 - updated and fixed (haven't been touched in a while)
398
399 Version 0.4.0 (24 November 2006)
400
401 * packaging changes:
402 - changed deprecated copyright attribute to license; added ldconfig
403 to post-(un)install steps; added devel package for liblinuxsampler;
404 to linuxsampler.spec (RPM)
405 - install necessary development header files for allowing 3rd party
406 applications to link against liblinuxsampler
407 - liblinuxsampler's API documentation can be generated with 'make docs'
408 (Doxygen required)
409 - added benchmark to automatically detect the best triangle LFO
410 implementation (currently either an integer math solution or a
411 di-harmonic approximation), automatic detection can be overriden
412 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
413 configure script argument though (mandatory for cross-compilation)
414 - do not automatically pick optimized gcc flags if the user already
415 provided some on his own (as CXXFLAGS)
416 - added compile time option to disable processing of All-Notes-Off MIDI
417 messages
418 - added compile time options to allow disabling the various audio and
419 MIDI drivers
420 - fixed automatic GCC CPU switch detection on PPC
421 (patch by Ebrahim Mayat)
422
423 * Gigasampler format engine:
424 - extensive synthesis optimization
425 (reimplementation of EGs and LFO(s), removed synthesis parameter
426 prerendering and the synthesis parameter matrix in general, splitting
427 each audio fragment into subfragments now where each subfragment uses
428 constant pitch and filter coefficients. The volume coefficient is
429 linearly interpolated inside a subfragment, unless
430 --disable-interpolate-volume is set.)
431 - fine tuning of the EG modulation parameters
432 - improved filter cutoff calculation by adding support for the
433 following gig parameters: Cutoff freq (used when no cutoff
434 controller is defined), Control invert, Minimum cutoff, Velocity
435 curve and Velocity range. The keyboard tracking now scales
436 cutoff frequency instead of resonance.
437 - added support for gig parameter Resonance.
438 - fixed bug in sysex handling (patch by Juan Linietsky)
439 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
440 which can be overridden with --enable-global-attenuation
441 - EG fixes: made the length of "attack hold" stage more
442 accurate. Release stage can now start before attack stage
443 ends. Cancel release didn't work when sustain was zero. Attack
444 time now has a minimal value to prevent clicks.
445 - fixed pitch changes larger than one octave
446 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
447 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
448 all modes can be altered via standard GM messages, that is CC5 for
449 altering portamento time, CC65 for enabling / disabling portamento
450 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
451 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
452 parameter) and crossfade
453 - added support for the "attenuation controller threshold" gig
454 parameter
455 - added smoothing of volume changes caused by control change
456 messages
457 - sample loop parameters are now taken from the DimensionRegion
458 instead of the wave chunk
459 - fixed keyswitching for v3 gigs with a number of keyswitch splits
460 not equal to a power of two
461 - reimplementation of the filter algorithm. The new filter is more
462 accurate and supports all gig filter types, including bandreject
463 and lowpass turbo.
464 - real support for 24 bit samples - samples are not truncated to
465 16 bits anymore
466 - support for aftertouch (channel pressure, not polyphonic
467 aftertouch)
468 - LFO1 behaviour fixed (dampening from max volume instead of
469 amplifying from 0)
470
471 * LSCP server:
472 - fixed application exit on broken pipe error (fixes bug #20)
473 - fixed the notification messages delay due to lack of
474 network activity (fixes bug #26)
475 - fixed parser bug which occured on space(s) within device parameters
476 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
477
478 * audio driver:
479 - added aRts audio output driver (by no means RT safe)
480
481 * MIDI driver:
482 - fixed legacy sysex code which caused dispatching of MIDI SysEx
483 messages several times instead of once
484 - API extension for MIDI drivers which already supply exact time stamps
485 for events (i.e. for offline rendering based MIDI drivers)
486 - added checks for bad MIDI data
487
488 * linuxsampler application:
489 - show available sampler engine types on startup
490
491 * general changes:
492 - support for muting sampler channels and solo mode of the same, two new
493 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
494 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
495 introduced for this, the behavior is the same like on a mixer console
496 (patch by Grigor Iliev, a bit adjusted). Also added configure option
497 --enable-process-muted-channels which can be used to enable the
498 processing of muted channels.
499 - support for sostenuto pedal
500 - support for monitoring the total number of active voices
501 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
502 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
503 - fixed some memory management errors
504 - fixed some concurrency problems that could lead to crashes when
505 LSCP commands were executed
506 - fixed crash when instrument loading failed previously on the same
507 sampler channel (fixes bug #36)
508
509 Version 0.3.3 (15 July 2005)
510
511 * packaging changes:
512 - fixed compilation with gcc 4.0
513
514 * Gigasampler format engine:
515 - LFO preprocessing was performed even though the respective LFO was
516 disabled by the instrument patch (minor efficiency fix)
517 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
518 for volume ramp downs in the same fragment (needed for current voice
519 stealing implementation) then simply inform the user with a warning
520 about possible click sounds and reduce the volume ramp down
521 appropriately instead of cancelling the audio device connection
522
523 Version 0.3.2 (24 June 2005)
524
525 * packaging changes:
526 - updated autotools build files to compile on OS X
527 (conditional compilation of CoreMIDI and MidiShare drivers)
528 - hand-crafted assembly optimization code can be disabled with
529 './configure --disable-asm' (definitely not recommended)
530 - fixed 'make dist' rule to include all necessary files
531 - require automake (>= 1.5) for 'make -f Makefile.cvs'
532 (due to 'dist-bzip2' automake option)
533
534 * Gigasampler format engine:
535 - support for the gig parameters for "release velocity response" curves
536 - fine tuning of the EGADSR envelope
537 - volume of release triggered samples now depends on note-on velocity,
538 note length and gig parameter "release trigger decay" instead of
539 note-off velocity.
540 - revised voice stealing
541 (fixes crash and endless loop caused by voice stealing)
542 - don't reset scale tuning on instrument or audio output device change
543 - handle key group conflicts right at the beginning of each fragment
544 instead of when the respective voice is actually launched
545 (fixes undefined behavior if stolen voices belonged to a key group -
546 this case was followed by a "killed voice survived" error message)
547 - fixed minor issue with null/silence samples
548 (those stole voices even though they don't need a voice at all which
549 resulted in "voice stealing didn't work out" messages)
550 - don't reset volume, pan, pitch and MIDI controller values on
551 instrument or audio output device change
552
553 * LSCP server:
554 - fixed some crashes (patch by Grigor Iliev, fixes #19)
555 - fixed LSCP event "CHANNEL_INFO" notification
556 (e.g. did not notify on volume changes or MIDI program change events)
557
558 * linuxsampler application:
559 - added command line parameters --lscp-addr and --lscp-port to override
560 default IP address and port of LSCP server
561
562 Version 0.3.1 (24 May 2005)
563
564 * initial release
