38 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
39 causing e.g. the libgig test to fail when
40 "./configure --disable-jack-driver" was used
41 (patch by Alexis Ballier)
42 - fixed compilation with gcc 4.3
43 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)

45 - fixes for building with newer MinGW versions
46 - fix for building with bison 2.4 (#111)
47 - fixed building with libgig installed in a non-standard directory
48 - minor fix in configure for mmsystem.h detection on MinGW
49 - Windows: look for editor plugins and Fantasia using base
50 directory of liblinuxsampler dll (look in the same directory and one
51 directory above)

53 - fixed building with sqlite installed in a non-standard directory
54 - when cross-compiling, don't try to create instruments.db
55 - fix for new mingw-w64 version, which has usleep
56
57 * general changes:
58 - bugfix: on some POSIX systems instrument editor plugins refused to
59 load as we used a non-portable Linux specific struct field
60 (fixes bug #70, patch by Ronald Baljeu)
61 - fixed endless loop which occured when loading an instrument editor
62 plugin DLL on Windows systems failed
63 - fixed memory leaks that occurred when liblinuxsampler was unloaded
64 - optimized the SynchronizedConfig class so it doesn't wait
65 unnecessarily long after an update
66 - added support for notifying instrument editors on note-on / note-off
67 events (e.g. to highlight the pressed keys on the virtual keyboard
68 of gigedit)
69 - added support for triggering notes by instrument editors (see above)
70 - be verbose on DLL load errors (on Linux)
71 - fixed di-harmonic triangle LFO implementation (this LFO implementation
72 is only used by very few systems, most pick the int math
73 implementation, which is usually faster)
74 - fixes for audio drivers with varying buffer sizes
75 - experimental support for running LinuxSampler as a DSSI, LV2 and
76 VST plugin
77 - notification events for stream/voice count statistics are now sent
78 only when there are actual changes
79 - added memory ordering constraints to improve stability on
80 multi-core and multi-cpu systems
81 - maximum voices and disk streams can now be altered at runtime
82 - fixed CPU feature detection on x86_64 (maybe fixes #108)
83 - automatic stacktrace mechanism is now turned off by default and can
84 be switched on by command line option "--stacktrace" (the automatic
85 stacktrace mechanism seems to be broken on most systems at the moment)
86 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
87 a pointer to the launched InstrumentEditor object
88 - added optional 3rd party user data parameter for following
89 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
90 InstrumentEditor::Launch(),
91 InstrumentManager::LaunchInstrumentEditor()
92 - theoretical fix: made SynchronizedConfig follow C++0x memory
93 model more strictly
94 - fixes for using large audio device buffers
95 - Windows: add the installation directory to the DLL search path
96 when loading an editor plugin (solves problems with VST and
97 gigedit on systems with other GTK versions installed)
98
99 * audio driver:
100 - removed the nonsense audio channel constraint (which was hard coded to
101 max. 100 audio channels) for most audio drivers
102 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
103 opposed to the LSCP specs
104 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
105 reflected the wrong value
106 - fixed a memory management bug in ASIO driver
107 - Makefile fix: JACK_CFLAGS wasn't used
108 - JACK: use jack_client_open instead of the deprecated
109 jack_client_new
110 - added (experimental) CoreAudio driver
111 - applied old fixes to the ASIO driver that were included in the
112 previous binary release but accidentally never committed to CVS
113 (fixes #117)
114 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
115 win64)
116 - VST: added support for sample rate and buffer size changes
117 - VST: close editor (Fantasia) when the VST is removed
118 - VST: avoid opening Fantasia more than once for each VST instance
119 - VST: export main function as "main" on Linux too (fix for
120 energyXT)
121 - VST: changed number of output channels from one stereo to 16
122 stereo
123 - added channel routing, fxsends and midi maps to the settings
124 stored in the plugin state
125 - performance optimization of AudioChannel::MixTo() and
126 AudioChannel::CopyTo() methods using GCC vector exensions
127 (if available)
128 - ASIO fixes: avoid initializing the device twice, avoid throwing
129 exception when getting parameters from a disconnected device
130
131 * MIDI driver:
132 - added JACK MIDI driver
133 - dispatch bank select as ordinary CC as well, the user might seriously
134 want to (mis)use it for some purpose ("fixed" in all current MIDI
135 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
136 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
137 CoreMidi or AU
138 - fixed mingw-w64 compilation error in MME driver
139 - made program change handling in MIDI thread real-time safe by
140 moving the logic to a non-RT thread
141 - fixed minor memory leak in ALSA driver
142
143 * instruments database:
144 - avoid time consuming samples scanning when adding instruments
145 to the instruments database
146 - added support for handling lost files in the instruments database
147 - Implemented option for adding instruments in separate directories
148 in the instruments database
149 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
150 - work-around for missing fnmatch function on Windows to make
151 instrument database compilable
152 - added instrument database support on Windows
153 works with both standalone mode and VST plugin.
154 the instruments DB file is located in
155 %USERPROFILE%\.linuxsampler\instruments.db which allows different
156 databases for each windows user
157 if no DB is present it automatically creates the .linuxsampler subdir
158 and then creates an empty DB
159 - fixed recursive import, which was broken on Windows
160
161 * Gigasampler format engine:
162 - fixed a memory leak that could happen when a channel was deleted
163 while notes were playing
164 - made it possible to load an instrument even if the audio thread
165 isn't running
166 - added partial support for the "Controller Triggered" MIDI rule,
167 enough for piano gigs with pedal noise samples
168 - minor fix: only mark FX sends as being modified if really the
169 respective FX send MIDI controller was used
170 - added support for GM global device volume SysEx message
171 (can be selected at compile time to either apply globally to the
172 whole sampler [default] or only to the sampler channels that are
173 connected to the respective MIDI input port the SysEx message arrived
174 on)
175 - bugfix: notes triggered at position 0 in the audio buffer were
176 sometimes wrongly killed in the same buffer, causing no sound to
177 be played
178 - added support for chromatic / drumkit mode Roland GS Sysex message
179 which is usally used to switch a part between chromatic sounds and
180 drumkit sounds (as opposed to their common default setting of MIDI
181 part 10 being a drumkit part and all other ones chromatic parts), in
182 LS however one can switch between the first 16 MIDI instrument maps
183 defined for the sampler
184 - made it possible to create multiple sample channels even if the
185 audio thread isn't running
186 - fixed crash when removing channel with active voices (#116)
187 - bugfix: on sample reference changes (instrument editor), only
188 un-cache the respective sample if it's really not used by any
189 sampler engine anymore
190 - re-cache samples in case they were changed by an instrument editor,
191 e.g. when a sample was added while playing (#82)
192 - fixed hanging notes which occured when note-off event had the exact
193 same time stamp as the voice's note-on event and occured both in the
194 same audio fragment cycle (fixes bug #112)
195 - added support for the "fine tune" and "pitch bend range"
196 instrument-level gig parameters
197 - fixed minor artifacts in pitch bend handling
198 - added support for GS Reset SysEx message
199 - allow gig files to use unlimited downward pitch shifting
200 - added a limit check for upward pitch shifting
201 - bugfix: sometimes, when playing a note twice fast, the second
202 note was silent
203 - fixed crash happening when a pitch bend event arrived at the
204 same time a new instrument was loading
205
206 * LSCP server:
207 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
208 react on MIDI data arriving on certain sampler channels (so far only
209 Note-On and Note-Off events are sent via this LSCP event)
210 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
211 react on MIDI data arriving on certain MIDI input devices (so far only
212 Note-On and Note-Off events are sent via this LSCP event)
213 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
214 SET DB_INSTRUMENT FILE_PATH
215 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
216 frontends to send MIDI messages to specific sampler channel
217 - added two additional fields to GET FILE INSTRUMENT INFO command -
218 KEY_BINDINGS and KEYSWITCH_BINDINGS
219 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
220 was incorrect
221 - Optimized the retrieval of the MIDI instrument mappings
222 - added new LSCP command "SET VOICES" to globally alter the maximum
223 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
224 be triggered respectively
225 - added new LSCP command "SET STREAMS" to globally alter the maximum
226 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
227 which will be triggered respectively
228 - bugfix: retry if "select" returns EINTR (this fixes a crash when
229 a gigedit file dialog is opened)
230 - close all connections when LSCPServer is deleted
231 - hard close of all sockets on exit
232 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
233 driver
234
235 * Bug fixes:
236 - fixed a crash which occurs when removing a sampler channel waiting
237 to start instrument loading after another channel
238 - fixed a crash which occurs when removing a sampler channel with
239 instrument loading in progress (bug #113)
240 - fixed termination caused by uncaught exception when adding MIDI
241 instrument with PERSISTENT load mode
242 - fixed possible iterator invalidations when resetting the sampler
243 - fixed memory leaks when issuing the following LSCP commands:
244 GET AUDIO_OUTPUT_DRIVER INFO
245 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
246 GET MIDI_INPUT_DRIVER INFO
247 GET MIDI_INPUT_DRIVER_PARAMETER INFO
248 - fixed possible compilation error when sqlite is not present
249 - fixed orphaned pointers when setting maximum voices limit (bug #118)
250 - fixed crash when changing the audio output device of a sampler
251 channel with loaded instrument and start playing notes
252 - fixed endless loop in Engine::SuspendAll() (bug #120)
253 - fixed a low-level atomic load function that was broken on 64-bit
254 PowerPC, which probably could cause crashes on that platform
255 - fixed a memory management error which could cause a crash when a
256 plugin was unloaded
257 - bugfix: two private structs had the same name, which could cause
258 problems if the linker chose the wrong constructor
259 - fixed low-level ConditionServer usage bug that caused lockups on
260 Windows
261
262
263 Version 0.5.1 (6 December 2007)
264
265 * packaging changes:
266 - added autoconf checks for pthread library
267 - added autoconf check for pthread bug found on certain NPTL-enabled
268 glibc versions (see Gentoo bug report #194076)
269 - added autoconf checks for MS Windows
270
271 * general changes:
272 - bugfix: the thread used by an editor plugin didn't die when the
273 editor closed
274 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
275 out all the space. operator--() did not apply size_mask after
276 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
277 order to avoid problems with the _NonVolatileReader functions.
278 - bugfix: Stream.h: added a missing divide by BytesPerSample in
279 GetWriteSpace(). Since this function is currently only used in
280 the stream's qsort() compare function, it didn't trigger any
281 bugs.
282 - Resampler.h, Synthesizer.h: cubic interpolation now works in
283 24bit mode too. Faster method to read 24bit words on little
284 endian machines (x86): replaced 3 byte reads + shifts with a 1
285 unaligned 32bit read and shift
286 - experimental support for MS Windows (MIDI input via MME, AUDIO
287 output via ASIO)
288 - made handling of SIGINT signal (Ctrl-C) a bit more robust
289 - support for monitoring the total number of active disk streams
290 (new LSCP commands: GET TOTAL_STREAM_COUNT,
291 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
292
293 * AUDIO driver:
294 - added Windows ASIO low latency audio driver
295
296 * MIDI driver:
297 - added MME Windows MIDI driver
298
299 * LSCP server:
300 - added support for Windows style path / filenames, however with
301 forward slash path separators instead of backslash
302 (i.e. "C:/foo/bar.gig")
303 - allow naughty liblscp to send non-string device parameters within
304 apostrophes as well
305 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
306 "LIST FILE INSTRUMENTS <file>" and
307 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
308 about an arbitrary instrument file on the system where the sampler is
309 running on
310
311 Version 0.5.0 (15 October 2007)
312
313 * packaging changes:
314 - config.h is not going to be installed along with liblinuxsampler's
315 API header files anymore
316 - only the API relevant header (and source) files will be exported to
317 the Doxygen API documentation (explicitly listed in Doxyfile.in)
318 - added completely new XCode project files for Mac OSX which is now
319 capable to execute our autoconf environment, thus no need anymore
320 to maintain the compile time configuration file (osx/version.h) for
321 OSX manually (patch by Toshi Nagata)
322 - fixed buggy boolean --enable-foo / --disable-foo configure script
323 parameters
324 - global.h now only covers global definitions that are needed for the
325 C++ API header files, all implementation internal global definitions
326 are now in global_private.h
327 - atomic.h is not exposed to the C++ API anymore
328 - no need to include config.h anymore for using LS's API header files
329 - fixed warnings in API doc generation
330
331 * general changes:
332 - replaced the old, confusing MIDI program change mechanism by a
333 flexible MIDI instrument mapper which allows to map arbitrary
334 (MIDI bank, MIDI program) pairs with arbitrary
335 (engine type, instrument file, file index) triplets which will be
336 loaded on the respective channel when such MIDI program change
337 messages arrive, beside that, each entry allows to define a life-time
338 strategy for the instrument, so the user can define whether the
339 instrument should i.e. be permanently loaded (to be able to switch
340 quickly among sounds) or i.e. loaded just on demand when the
341 respective program change arrives (to safe RAM space), as well as a
342 global volume factor for each entry, so the user can adjust the volume
343 dynamic of his mapped instrument collection without having to modify
344 the instrument files, also one can manage arbitrary amount of such
345 MIDI instrument maps and assign each sampler channel individually
346 a certain map, so that i.e. separation of normal instruments and
347 drumkits is possible
348 - new notification events for tracking changes to audio/MIDI devices,
349 MIDI instrument maps, MIDI instruments, FX sends, global volume.
350 - sampler was limited to load max. 200 instruments in the background
351 due to a constant size RingBuffer FIFO which is now replaced by a
352 dynamic (unlimited) size std::list FIFO
353 - added FX sends, these allow to route audio signals to arbitrary audio
354 output channels for being processed by external effect processors
355 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
356 controllers
357 - global (sampler wide) volume can now be controlled at runtime
358 - Implemented new, improved notification system
359 - fixed compilation errors regarding OSX
360 (patch by Toshi Nagata)
361 - implemented instruments database
362 - added support for escape sequences to the instruments database
363 - added highly experimental support for on-the-fly instrument editing
364 within the sampler's process (by using instrument editor plugins),
365 you'll notice the new "Registered instrument editors:" message on
366 startup, added a new LSCP command:
367 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
368 to spawn a matching instrument editor for the instrument on the
369 given sampler channel, the plugin path can be overridden at compile
370 time with ./configure --enable-plugin-dir=/some/dir
371 - added experimental code for synchronizing instrument editors hosted
372 in the sampler's process to safely edit instruments while playing
373 without a crash (hopefully) by either suspending single regions
374 wherever possible or if unavoidable whole engine(s)
375 - fixed several issues in fundamental "Thread" class: set scheduling
376 policy and priority on thread level, set a minimum stack size for
377 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
378 threads simply inherited properties of starting thread instead of
379 setting their own policy and priority
380 - minor fix in our automatic stack trace mechanism on crashes, the
381 main process did not wait for the stack trace process to finish
382 its output
383 - fixed some minor memory leaks
384 - reenabled assembly features support, at the moment only for
385 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
386 - minor assembly fix in x86 features detection (don't use the PIC
387 register, to avoid relocations in the text segment at runtime)
388 - POSIX callback functions of Thread.h are hidden
389
390 * MIDI driver:
391 - dispatch bank select (MSB and LSB) messages
392
393 * audio driver:
394 - the ALSA audio output driver parameters now reflect the correct
395 parameter value ranges for the respective selected sound card
396 (patch by Till Wimmer, a bit fixed and extended)
397
398 * Gigasampler format engine:
399 - if a filter is used and EG2 finishes before EG1, let the voice
400 die when EG2 has finished (this fixes a problem with clicks and
401 voice starvation for some gigs)
402 - playback is no longer disabled during instrument loading
403 - all notes playing on a channel that changes its instrument keep
404 playing with the old instrument until they get a note off
405 command
406 - EG fix: a release value of zero could cause noises or crash
407 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
408 - EG fine tuning: when attack is zero the EG starts at a level
409 above max sustain level, which means that there is a decay phase
410 even if sustain is 100%
411 - more EG fixes: the level could sometimes go below zero and cause
412 noises or crashes
413 - minor fix of EGDecay (patch by Toshi Nagata)
414 - fixed compiler error when --enable-override-filter-type was
415 supplied to the configure script (fixes #46)
416 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
417 instead of a fix value
418 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
419 127 (solo mode) only kill voices if the respective mode really
420 changed
421
422 * LSCP server:
423 - fixed compile time error for old Bison versions
424 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
425 - parser now supports extended ASCII character set
426 (up to ASCII code 255, i.e. includes now umlauts and accents)
427 - filename arguments in LSCP commands now allow to use escape
428 sequences, that is directly literal as one of: \', \", \\, \n, \r,
429 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
430 code value like \xf2) (fixes bug #24)
431 - the following LSCP commands now also support escape sequences for at
432 least one of their text-based parameters (i.e. name, description):
433 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
434 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
435 "SET DB_INSTRUMENT_DIRECTORY NAME",
436 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
437 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
438 "FIND DB_INSTRUMENT_DIRECTORIES"
439 - returns verbose syntax errors (line and column where syntax error
440 occured, the unexpected character and the actually expected, possible
441 character(s), the latter only if less than 5 possibilities)
442 - made sure that LSCP syntax is not affected by gigedit locale
443 settings
444 - bugfix regarding strings parameter lists: all comma separated lists
445 of strings were treated as being one string containing commas
446 (fixes #57)
447
448 * Bug fixes:
449 - fixed crash occurring on certain LSCP scripts (Bug 39)
450 - another thread safety fix for lscp "load engine" and "set
451 channel audio output device"
452 - fixed a crash which occurs when reassigning the same engine
453 on a sampler channel with connected MIDI device
454 - fixed a crash which occurs when changing the number of ports of a MIDI
455 device connected to a sampler channel to number less then or equal
456 to the index of the port to which the sampler channel is connected.
457 - The previous bindings were not been disconnected when altering
458 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
459 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
460 - The active stream/voice count statistic was incorrect.
461 - notification events were not been sent for some sampler
462 channel changes
463 - added default min and max values to restrict the number of allowed
464 audio output channels and MIDI input ports
465 - the connection to the PCM interface is now closed when destroying
466 an audio output device
467 - files with slash in their path or filename could not be loaded
468
469 * test cases:
470 - updated and fixed (haven't been touched in a while)
471
472 Version 0.4.0 (24 November 2006)
473
474 * packaging changes:
475 - changed deprecated copyright attribute to license; added ldconfig
476 to post-(un)install steps; added devel package for liblinuxsampler;
477 to linuxsampler.spec (RPM)
478 - install necessary development header files for allowing 3rd party
479 applications to link against liblinuxsampler
480 - liblinuxsampler's API documentation can be generated with 'make docs'
481 (Doxygen required)
482 - added benchmark to automatically detect the best triangle LFO
483 implementation (currently either an integer math solution or a
484 di-harmonic approximation), automatic detection can be overriden
485 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
486 configure script argument though (mandatory for cross-compilation)
487 - do not automatically pick optimized gcc flags if the user already
488 provided some on his own (as CXXFLAGS)
489 - added compile time option to disable processing of All-Notes-Off MIDI
490 messages
491 - added compile time options to allow disabling the various audio and
492 MIDI drivers
493 - fixed automatic GCC CPU switch detection on PPC
494 (patch by Ebrahim Mayat)
495
496 * Gigasampler format engine:
497 - extensive synthesis optimization
498 (reimplementation of EGs and LFO(s), removed synthesis parameter
499 prerendering and the synthesis parameter matrix in general, splitting
500 each audio fragment into subfragments now where each subfragment uses
501 constant pitch and filter coefficients. The volume coefficient is
502 linearly interpolated inside a subfragment, unless
503 --disable-interpolate-volume is set.)
504 - fine tuning of the EG modulation parameters
505 - improved filter cutoff calculation by adding support for the
506 following gig parameters: Cutoff freq (used when no cutoff
507 controller is defined), Control invert, Minimum cutoff, Velocity
508 curve and Velocity range. The keyboard tracking now scales
509 cutoff frequency instead of resonance.
510 - added support for gig parameter Resonance.
511 - fixed bug in sysex handling (patch by Juan Linietsky)
512 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
513 which can be overridden with --enable-global-attenuation
514 - EG fixes: made the length of "attack hold" stage more
515 accurate. Release stage can now start before attack stage
516 ends. Cancel release didn't work when sustain was zero. Attack
517 time now has a minimal value to prevent clicks.
518 - fixed pitch changes larger than one octave
519 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
520 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
521 all modes can be altered via standard GM messages, that is CC5 for
522 altering portamento time, CC65 for enabling / disabling portamento
523 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
524 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
525 parameter) and crossfade
526 - added support for the "attenuation controller threshold" gig
527 parameter
528 - added smoothing of volume changes caused by control change
529 messages
530 - sample loop parameters are now taken from the DimensionRegion
531 instead of the wave chunk
532 - fixed keyswitching for v3 gigs with a number of keyswitch splits
533 not equal to a power of two
534 - reimplementation of the filter algorithm. The new filter is more
535 accurate and supports all gig filter types, including bandreject
536 and lowpass turbo.
537 - real support for 24 bit samples - samples are not truncated to
538 16 bits anymore
539 - support for aftertouch (channel pressure, not polyphonic
540 aftertouch)
541 - LFO1 behaviour fixed (dampening from max volume instead of
542 amplifying from 0)
543
544 * LSCP server:
545 - fixed application exit on broken pipe error (fixes bug #20)
546 - fixed the notification messages delay due to lack of
547 network activity (fixes bug #26)
548 - fixed parser bug which occured on space(s) within device parameters
549 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
550
551 * audio driver:
552 - added aRts audio output driver (by no means RT safe)
553
554 * MIDI driver:
555 - fixed legacy sysex code which caused dispatching of MIDI SysEx
556 messages several times instead of once
557 - API extension for MIDI drivers which already supply exact time stamps
558 for events (i.e. for offline rendering based MIDI drivers)
559 - added checks for bad MIDI data
560
561 * linuxsampler application:
562 - show available sampler engine types on startup
563
564 * general changes:
565 - support for muting sampler channels and solo mode of the same, two new
566 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
567 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
568 introduced for this, the behavior is the same like on a mixer console
569 (patch by Grigor Iliev, a bit adjusted). Also added configure option
570 --enable-process-muted-channels which can be used to enable the
571 processing of muted channels.
572 - support for sostenuto pedal
573 - support for monitoring the total number of active voices
574 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
575 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
576 - fixed some memory management errors
577 - fixed some concurrency problems that could lead to crashes when
578 LSCP commands were executed
579 - fixed crash when instrument loading failed previously on the same
580 sampler channel (fixes bug #36)
581
582 Version 0.3.3 (15 July 2005)
583
584 * packaging changes:
585 - fixed compilation with gcc 4.0
586
587 * Gigasampler format engine:
588 - LFO preprocessing was performed even though the respective LFO was
589 disabled by the instrument patch (minor efficiency fix)
590 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
591 for volume ramp downs in the same fragment (needed for current voice
592 stealing implementation) then simply inform the user with a warning
593 about possible click sounds and reduce the volume ramp down
594 appropriately instead of cancelling the audio device connection
595
596 Version 0.3.2 (24 June 2005)
597
598 * packaging changes:
599 - updated autotools build files to compile on OS X
600 (conditional compilation of CoreMIDI and MidiShare drivers)
601 - hand-crafted assembly optimization code can be disabled with
602 './configure --disable-asm' (definitely not recommended)
603 - fixed 'make dist' rule to include all necessary files
604 - require automake (>= 1.5) for 'make -f Makefile.cvs'
605 (due to 'dist-bzip2' automake option)
606
607 * Gigasampler format engine:
608 - support for the gig parameters for "release velocity response" curves
609 - fine tuning of the EGADSR envelope
610 - volume of release triggered samples now depends on note-on velocity,
611 note length and gig parameter "release trigger decay" instead of
612 note-off velocity.
613 - revised voice stealing
614 (fixes crash and endless loop caused by voice stealing)
615 - don't reset scale tuning on instrument or audio output device change
616 - handle key group conflicts right at the beginning of each fragment
617 instead of when the respective voice is actually launched
618 (fixes undefined behavior if stolen voices belonged to a key group -
619 this case was followed by a "killed voice survived" error message)
620 - fixed minor issue with null/silence samples
621 (those stole voices even though they don't need a voice at all which
622 resulted in "voice stealing didn't work out" messages)
623 - don't reset volume, pan, pitch and MIDI controller values on
624 instrument or audio output device change
625
626 * LSCP server:
627 - fixed some crashes (patch by Grigor Iliev, fixes #19)
628 - fixed LSCP event "CHANNEL_INFO" notification
629 (e.g. did not notify on volume changes or MIDI program change events)
630
631 * linuxsampler application:
632 - added command line parameters --lscp-addr and --lscp-port to override
633 default IP address and port of LSCP server
634
635 Version 0.3.1 (24 May 2005)
636
637 * initial release
