28 Version 1.0.0 (31 July 2009)
29
30 * packaging changes:
31 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
32 causing e.g. the libgig test to fail when
33 "./configure --disable-jack-driver" was used
34 (patch by Alexis Ballier)
35 - fixed compilation with gcc 4.3
36 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
37 - fixed configure so it detects x86_64 (#107)
38 - fixes for building with newer MinGW versions
39 - fix for building with bison 2.4 (#111)
40 - fixed building with libgig installed in a non-standard directory
41 - minor fix in configure for mmsystem.h detection on MinGW
42 - Windows: look for editor plugins and Fantasia using base
43 directory of liblinuxsampler dll (look in the same directory and one
44 directory above)
45 - configure script fix: removed unconditional use of SSE
46 - fixed building with sqlite installed in a non-standard directory
47 - when cross-compiling, don't try to create instruments.db
48 - fix for new mingw-w64 version, which has usleep
49
50 * general changes:
51 - bugfix: on some POSIX systems instrument editor plugins refused to
52 load as we used a non-portable Linux specific struct field
53 (fixes bug #70, patch by Ronald Baljeu)
54 - fixed endless loop which occured when loading an instrument editor
55 plugin DLL on Windows systems failed
56 - fixed memory leaks that occurred when liblinuxsampler was unloaded
57 - optimized the SynchronizedConfig class so it doesn't wait
58 unnecessarily long after an update
59 - added support for notifying instrument editors on note-on / note-off
60 events (e.g. to highlight the pressed keys on the virtual keyboard
61 of gigedit)
62 - added support for triggering notes by instrument editors (see above)
63 - be verbose on DLL load errors (on Linux)
64 - fixed di-harmonic triangle LFO implementation (this LFO implementation
65 is only used by very few systems, most pick the int math
66 implementation, which is usually faster)
67 - fixes for audio drivers with varying buffer sizes
68 - experimental support for running LinuxSampler as a DSSI, LV2 and
69 VST plugin
70 - notification events for stream/voice count statistics are now sent
71 only when there are actual changes
72 - added memory ordering constraints to improve stability on
73 multi-core and multi-cpu systems
74 - maximum voices and disk streams can now be altered at runtime
75 - fixed CPU feature detection on x86_64 (maybe fixes #108)
76 - automatic stacktrace mechanism is now turned off by default and can
77 be switched on by command line option "--stacktrace" (the automatic
78 stacktrace mechanism seems to be broken on most systems at the moment)
79 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
80 a pointer to the launched InstrumentEditor object
81 - added optional 3rd party user data parameter for following
82 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
83 InstrumentEditor::Launch(),
84 InstrumentManager::LaunchInstrumentEditor()
85 - theoretical fix: made SynchronizedConfig follow C++0x memory
86 model more strictly
87 - fixes for using large audio device buffers
88 - Windows: add the installation directory to the DLL search path
89 when loading an editor plugin (solves problems with VST and
90 gigedit on systems with other GTK versions installed)
91
92 * audio driver:
93 - removed the nonsense audio channel constraint (which was hard coded to
94 max. 100 audio channels) for most audio drivers
95 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
96 opposed to the LSCP specs
97 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
98 reflected the wrong value
99 - fixed a memory management bug in ASIO driver
100 - Makefile fix: JACK_CFLAGS wasn't used
101 - JACK: use jack_client_open instead of the deprecated
102 jack_client_new
103 - added (experimental) CoreAudio driver
104 - applied old fixes to the ASIO driver that were included in the
105 previous binary release but accidentally never committed to CVS
106 (fixes #117)
107 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
108 win64)
109 - VST: added support for sample rate and buffer size changes
110 - VST: close editor (Fantasia) when the VST is removed
111 - VST: avoid opening Fantasia more than once for each VST instance
112 - VST: export main function as "main" on Linux too (fix for
113 energyXT)
114 - VST: changed number of output channels from one stereo to 16
115 stereo
116 - added channel routing, fxsends and midi maps to the settings
117 stored in the plugin state
118 - performance optimization of AudioChannel::MixTo() and
119 AudioChannel::CopyTo() methods using GCC vector exensions
120 (if available)
121 - ASIO fixes: avoid initializing the device twice, avoid throwing
122 exception when getting parameters from a disconnected device
123
124 * MIDI driver:
125 - added JACK MIDI driver
126 - dispatch bank select as ordinary CC as well, the user might seriously
127 want to (mis)use it for some purpose ("fixed" in all current MIDI
128 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
129 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
130 CoreMidi or AU
131 - fixed mingw-w64 compilation error in MME driver
132 - made program change handling in MIDI thread real-time safe by
133 moving the logic to a non-RT thread
134 - fixed minor memory leak in ALSA driver
135
136 * instruments database:
137 - avoid time consuming samples scanning when adding instruments
138 to the instruments database
139 - added support for handling lost files in the instruments database
140 - Implemented option for adding instruments in separate directories
141 in the instruments database
142 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
143 - work-around for missing fnmatch function on Windows to make
144 instrument database compilable
145 - added instrument database support on Windows
146 works with both standalone mode and VST plugin.
147 the instruments DB file is located in
148 %USERPROFILE%\.linuxsampler\instruments.db which allows different
149 databases for each windows user
150 if no DB is present it automatically creates the .linuxsampler subdir
151 and then creates an empty DB
152 - fixed recursive import, which was broken on Windows
153
154 * Gigasampler format engine:
155 - fixed a memory leak that could happen when a channel was deleted
156 while notes were playing
157 - made it possible to load an instrument even if the audio thread
158 isn't running
159 - added partial support for the "Controller Triggered" MIDI rule,
160 enough for piano gigs with pedal noise samples
161 - minor fix: only mark FX sends as being modified if really the
162 respective FX send MIDI controller was used
163 - added support for GM global device volume SysEx message
164 (can be selected at compile time to either apply globally to the
165 whole sampler [default] or only to the sampler channels that are
166 connected to the respective MIDI input port the SysEx message arrived
167 on)
168 - bugfix: notes triggered at position 0 in the audio buffer were
169 sometimes wrongly killed in the same buffer, causing no sound to
170 be played
171 - added support for chromatic / drumkit mode Roland GS Sysex message
172 which is usally used to switch a part between chromatic sounds and
173 drumkit sounds (as opposed to their common default setting of MIDI
174 part 10 being a drumkit part and all other ones chromatic parts), in
175 LS however one can switch between the first 16 MIDI instrument maps
176 defined for the sampler
177 - made it possible to create multiple sample channels even if the
178 audio thread isn't running
179 - fixed crash when removing channel with active voices (#116)
180 - bugfix: on sample reference changes (instrument editor), only
181 un-cache the respective sample if it's really not used by any
182 sampler engine anymore
183 - re-cache samples in case they were changed by an instrument editor,
184 e.g. when a sample was added while playing (#82)
185 - fixed hanging notes which occured when note-off event had the exact
186 same time stamp as the voice's note-on event and occured both in the
187 same audio fragment cycle (fixes bug #112)
188 - added support for the "fine tune" and "pitch bend range"
189 instrument-level gig parameters
190 - fixed minor artifacts in pitch bend handling
191 - added support for GS Reset SysEx message
192 - allow gig files to use unlimited downward pitch shifting
193 - added a limit check for upward pitch shifting
194 - bugfix: sometimes, when playing a note twice fast, the second
195 note was silent
196 - fixed crash happening when a pitch bend event arrived at the
197 same time a new instrument was loading
198
199 * LSCP server:
200 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
201 react on MIDI data arriving on certain sampler channels (so far only
202 Note-On and Note-Off events are sent via this LSCP event)
203 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
204 react on MIDI data arriving on certain MIDI input devices (so far only
205 Note-On and Note-Off events are sent via this LSCP event)
206 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
207 SET DB_INSTRUMENT FILE_PATH
208 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
209 frontends to send MIDI messages to specific sampler channel
210 - added two additional fields to GET FILE INSTRUMENT INFO command -
211 KEY_BINDINGS and KEYSWITCH_BINDINGS
212 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
213 was incorrect
214 - Optimized the retrieval of the MIDI instrument mappings
215 - added new LSCP command "SET VOICES" to globally alter the maximum
216 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
217 be triggered respectively
218 - added new LSCP command "SET STREAMS" to globally alter the maximum
219 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
220 which will be triggered respectively
221 - bugfix: retry if "select" returns EINTR (this fixes a crash when
222 a gigedit file dialog is opened)
223 - close all connections when LSCPServer is deleted
224 - hard close of all sockets on exit
225 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
226 driver
227
228 * Bug fixes:
229 - fixed a crash which occurs when removing a sampler channel waiting
230 to start instrument loading after another channel
231 - fixed a crash which occurs when removing a sampler channel with
232 instrument loading in progress (bug #113)
233 - fixed termination caused by uncaught exception when adding MIDI
234 instrument with PERSISTENT load mode
235 - fixed possible iterator invalidations when resetting the sampler
236 - fixed memory leaks when issuing the following LSCP commands:
237 GET AUDIO_OUTPUT_DRIVER INFO
238 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
239 GET MIDI_INPUT_DRIVER INFO
240 GET MIDI_INPUT_DRIVER_PARAMETER INFO
241 - fixed possible compilation error when sqlite is not present
242 - fixed orphaned pointers when setting maximum voices limit (bug #118)
243 - fixed crash when changing the audio output device of a sampler
244 channel with loaded instrument and start playing notes
245 - fixed endless loop in Engine::SuspendAll() (bug #120)
246 - fixed a low-level atomic load function that was broken on 64-bit
247 PowerPC, which probably could cause crashes on that platform
248 - fixed a memory management error which could cause a crash when a
249 plugin was unloaded
250 - bugfix: two private structs had the same name, which could cause
251 problems if the linker chose the wrong constructor
252 - fixed low-level ConditionServer usage bug that caused lockups on
253 Windows
254
255
256 Version 0.5.1 (6 December 2007)
257
258 * packaging changes:
259 - added autoconf checks for pthread library
260 - added autoconf check for pthread bug found on certain NPTL-enabled
261 glibc versions (see Gentoo bug report #194076)
262 - added autoconf checks for MS Windows
263
264 * general changes:
265 - bugfix: the thread used by an editor plugin didn't die when the
266 editor closed
267 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
268 out all the space. operator--() did not apply size_mask after
269 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
270 order to avoid problems with the _NonVolatileReader functions.
271 - bugfix: Stream.h: added a missing divide by BytesPerSample in
272 GetWriteSpace(). Since this function is currently only used in
273 the stream's qsort() compare function, it didn't trigger any
274 bugs.
275 - Resampler.h, Synthesizer.h: cubic interpolation now works in
276 24bit mode too. Faster method to read 24bit words on little
277 endian machines (x86): replaced 3 byte reads + shifts with a 1
278 unaligned 32bit read and shift
279 - experimental support for MS Windows (MIDI input via MME, AUDIO
280 output via ASIO)
281 - made handling of SIGINT signal (Ctrl-C) a bit more robust
282 - support for monitoring the total number of active disk streams
283 (new LSCP commands: GET TOTAL_STREAM_COUNT,
284 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
285
286 * AUDIO driver:
287 - added Windows ASIO low latency audio driver
288
289 * MIDI driver:
290 - added MME Windows MIDI driver
291
292 * LSCP server:
293 - added support for Windows style path / filenames, however with
294 forward slash path separators instead of backslash
295 (i.e. "C:/foo/bar.gig")
296 - allow naughty liblscp to send non-string device parameters within
297 apostrophes as well
298 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
299 "LIST FILE INSTRUMENTS <file>" and
300 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
301 about an arbitrary instrument file on the system where the sampler is
302 running on
303
304 Version 0.5.0 (15 October 2007)
305
306 * packaging changes:
307 - config.h is not going to be installed along with liblinuxsampler's
308 API header files anymore
309 - only the API relevant header (and source) files will be exported to
310 the Doxygen API documentation (explicitly listed in Doxyfile.in)
311 - added completely new XCode project files for Mac OSX which is now
312 capable to execute our autoconf environment, thus no need anymore
313 to maintain the compile time configuration file (osx/version.h) for
314 OSX manually (patch by Toshi Nagata)
315 - fixed buggy boolean --enable-foo / --disable-foo configure script
316 parameters
317 - global.h now only covers global definitions that are needed for the
318 C++ API header files, all implementation internal global definitions
319 are now in global_private.h
320 - atomic.h is not exposed to the C++ API anymore
321 - no need to include config.h anymore for using LS's API header files
322 - fixed warnings in API doc generation
323
324 * general changes:
325 - replaced the old, confusing MIDI program change mechanism by a
326 flexible MIDI instrument mapper which allows to map arbitrary
327 (MIDI bank, MIDI program) pairs with arbitrary
328 (engine type, instrument file, file index) triplets which will be
329 loaded on the respective channel when such MIDI program change
330 messages arrive, beside that, each entry allows to define a life-time
331 strategy for the instrument, so the user can define whether the
332 instrument should i.e. be permanently loaded (to be able to switch
333 quickly among sounds) or i.e. loaded just on demand when the
334 respective program change arrives (to safe RAM space), as well as a
335 global volume factor for each entry, so the user can adjust the volume
336 dynamic of his mapped instrument collection without having to modify
337 the instrument files, also one can manage arbitrary amount of such
338 MIDI instrument maps and assign each sampler channel individually
339 a certain map, so that i.e. separation of normal instruments and
340 drumkits is possible
341 - new notification events for tracking changes to audio/MIDI devices,
342 MIDI instrument maps, MIDI instruments, FX sends, global volume.
343 - sampler was limited to load max. 200 instruments in the background
344 due to a constant size RingBuffer FIFO which is now replaced by a
345 dynamic (unlimited) size std::list FIFO
346 - added FX sends, these allow to route audio signals to arbitrary audio
347 output channels for being processed by external effect processors
348 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
349 controllers
350 - global (sampler wide) volume can now be controlled at runtime
351 - Implemented new, improved notification system
352 - fixed compilation errors regarding OSX
353 (patch by Toshi Nagata)
354 - implemented instruments database
355 - added support for escape sequences to the instruments database
356 - added highly experimental support for on-the-fly instrument editing
357 within the sampler's process (by using instrument editor plugins),
358 you'll notice the new "Registered instrument editors:" message on
359 startup, added a new LSCP command:
360 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
361 to spawn a matching instrument editor for the instrument on the
362 given sampler channel, the plugin path can be overridden at compile
363 time with ./configure --enable-plugin-dir=/some/dir
364 - added experimental code for synchronizing instrument editors hosted
365 in the sampler's process to safely edit instruments while playing
366 without a crash (hopefully) by either suspending single regions
367 wherever possible or if unavoidable whole engine(s)
368 - fixed several issues in fundamental "Thread" class: set scheduling
369 policy and priority on thread level, set a minimum stack size for
370 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
371 threads simply inherited properties of starting thread instead of
372 setting their own policy and priority
373 - minor fix in our automatic stack trace mechanism on crashes, the
374 main process did not wait for the stack trace process to finish
375 its output
376 - fixed some minor memory leaks
377 - reenabled assembly features support, at the moment only for
378 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
379 - minor assembly fix in x86 features detection (don't use the PIC
380 register, to avoid relocations in the text segment at runtime)
381 - POSIX callback functions of Thread.h are hidden
382
383 * MIDI driver:
384 - dispatch bank select (MSB and LSB) messages
385
386 * audio driver:
387 - the ALSA audio output driver parameters now reflect the correct
388 parameter value ranges for the respective selected sound card
389 (patch by Till Wimmer, a bit fixed and extended)
390
391 * Gigasampler format engine:
392 - if a filter is used and EG2 finishes before EG1, let the voice
393 die when EG2 has finished (this fixes a problem with clicks and
394 voice starvation for some gigs)
395 - playback is no longer disabled during instrument loading
396 - all notes playing on a channel that changes its instrument keep
397 playing with the old instrument until they get a note off
398 command
399 - EG fix: a release value of zero could cause noises or crash
400 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
401 - EG fine tuning: when attack is zero the EG starts at a level
402 above max sustain level, which means that there is a decay phase
403 even if sustain is 100%
404 - more EG fixes: the level could sometimes go below zero and cause
405 noises or crashes
406 - minor fix of EGDecay (patch by Toshi Nagata)
407 - fixed compiler error when --enable-override-filter-type was
408 supplied to the configure script (fixes #46)
409 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
410 instead of a fix value
411 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
412 127 (solo mode) only kill voices if the respective mode really
413 changed
414
415 * LSCP server:
416 - fixed compile time error for old Bison versions
417 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
418 - parser now supports extended ASCII character set
419 (up to ASCII code 255, i.e. includes now umlauts and accents)
420 - filename arguments in LSCP commands now allow to use escape
421 sequences, that is directly literal as one of: \', \", \\, \n, \r,
422 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
423 code value like \xf2) (fixes bug #24)
424 - the following LSCP commands now also support escape sequences for at
425 least one of their text-based parameters (i.e. name, description):
426 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
427 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
428 "SET DB_INSTRUMENT_DIRECTORY NAME",
429 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
430 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
431 "FIND DB_INSTRUMENT_DIRECTORIES"
432 - returns verbose syntax errors (line and column where syntax error
433 occured, the unexpected character and the actually expected, possible
434 character(s), the latter only if less than 5 possibilities)
435 - made sure that LSCP syntax is not affected by gigedit locale
436 settings
437 - bugfix regarding strings parameter lists: all comma separated lists
438 of strings were treated as being one string containing commas
439 (fixes #57)
440
441 * Bug fixes:
442 - fixed crash occurring on certain LSCP scripts (Bug 39)
443 - another thread safety fix for lscp "load engine" and "set
444 channel audio output device"
445 - fixed a crash which occurs when reassigning the same engine
446 on a sampler channel with connected MIDI device
447 - fixed a crash which occurs when changing the number of ports of a MIDI
448 device connected to a sampler channel to number less then or equal
449 to the index of the port to which the sampler channel is connected.
450 - The previous bindings were not been disconnected when altering
451 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
452 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
453 - The active stream/voice count statistic was incorrect.
454 - notification events were not been sent for some sampler
455 channel changes
456 - added default min and max values to restrict the number of allowed
457 audio output channels and MIDI input ports
458 - the connection to the PCM interface is now closed when destroying
459 an audio output device
460 - files with slash in their path or filename could not be loaded
461
462 * test cases:
463 - updated and fixed (haven't been touched in a while)
464
465 Version 0.4.0 (24 November 2006)
466
467 * packaging changes:
468 - changed deprecated copyright attribute to license; added ldconfig
469 to post-(un)install steps; added devel package for liblinuxsampler;
470 to linuxsampler.spec (RPM)
471 - install necessary development header files for allowing 3rd party
472 applications to link against liblinuxsampler
473 - liblinuxsampler's API documentation can be generated with 'make docs'
474 (Doxygen required)
475 - added benchmark to automatically detect the best triangle LFO
476 implementation (currently either an integer math solution or a
477 di-harmonic approximation), automatic detection can be overriden
478 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
479 configure script argument though (mandatory for cross-compilation)
480 - do not automatically pick optimized gcc flags if the user already
481 provided some on his own (as CXXFLAGS)
482 - added compile time option to disable processing of All-Notes-Off MIDI
483 messages
484 - added compile time options to allow disabling the various audio and
485 MIDI drivers
486 - fixed automatic GCC CPU switch detection on PPC
487 (patch by Ebrahim Mayat)
488
489 * Gigasampler format engine:
490 - extensive synthesis optimization
491 (reimplementation of EGs and LFO(s), removed synthesis parameter
492 prerendering and the synthesis parameter matrix in general, splitting
493 each audio fragment into subfragments now where each subfragment uses
494 constant pitch and filter coefficients. The volume coefficient is
495 linearly interpolated inside a subfragment, unless
496 --disable-interpolate-volume is set.)
497 - fine tuning of the EG modulation parameters
498 - improved filter cutoff calculation by adding support for the
499 following gig parameters: Cutoff freq (used when no cutoff
500 controller is defined), Control invert, Minimum cutoff, Velocity
501 curve and Velocity range. The keyboard tracking now scales
502 cutoff frequency instead of resonance.
503 - added support for gig parameter Resonance.
504 - fixed bug in sysex handling (patch by Juan Linietsky)
505 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
506 which can be overridden with --enable-global-attenuation
507 - EG fixes: made the length of "attack hold" stage more
508 accurate. Release stage can now start before attack stage
509 ends. Cancel release didn't work when sustain was zero. Attack
510 time now has a minimal value to prevent clicks.
511 - fixed pitch changes larger than one octave
512 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
513 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
514 all modes can be altered via standard GM messages, that is CC5 for
515 altering portamento time, CC65 for enabling / disabling portamento
516 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
517 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
518 parameter) and crossfade
519 - added support for the "attenuation controller threshold" gig
520 parameter
521 - added smoothing of volume changes caused by control change
522 messages
523 - sample loop parameters are now taken from the DimensionRegion
524 instead of the wave chunk
525 - fixed keyswitching for v3 gigs with a number of keyswitch splits
526 not equal to a power of two
527 - reimplementation of the filter algorithm. The new filter is more
528 accurate and supports all gig filter types, including bandreject
529 and lowpass turbo.
530 - real support for 24 bit samples - samples are not truncated to
531 16 bits anymore
532 - support for aftertouch (channel pressure, not polyphonic
533 aftertouch)
534 - LFO1 behaviour fixed (dampening from max volume instead of
535 amplifying from 0)
536
537 * LSCP server:
538 - fixed application exit on broken pipe error (fixes bug #20)
539 - fixed the notification messages delay due to lack of
540 network activity (fixes bug #26)
541 - fixed parser bug which occured on space(s) within device parameters
542 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
543
544 * audio driver:
545 - added aRts audio output driver (by no means RT safe)
546
547 * MIDI driver:
548 - fixed legacy sysex code which caused dispatching of MIDI SysEx
549 messages several times instead of once
550 - API extension for MIDI drivers which already supply exact time stamps
551 for events (i.e. for offline rendering based MIDI drivers)
552 - added checks for bad MIDI data
553
554 * linuxsampler application:
555 - show available sampler engine types on startup
556
557 * general changes:
558 - support for muting sampler channels and solo mode of the same, two new
559 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
560 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
561 introduced for this, the behavior is the same like on a mixer console
562 (patch by Grigor Iliev, a bit adjusted). Also added configure option
563 --enable-process-muted-channels which can be used to enable the
564 processing of muted channels.
565 - support for sostenuto pedal
566 - support for monitoring the total number of active voices
567 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
568 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
569 - fixed some memory management errors
570 - fixed some concurrency problems that could lead to crashes when
571 LSCP commands were executed
572 - fixed crash when instrument loading failed previously on the same
573 sampler channel (fixes bug #36)
574
575 Version 0.3.3 (15 July 2005)
576
577 * packaging changes:
578 - fixed compilation with gcc 4.0
579
580 * Gigasampler format engine:
581 - LFO preprocessing was performed even though the respective LFO was
582 disabled by the instrument patch (minor efficiency fix)
583 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
584 for volume ramp downs in the same fragment (needed for current voice
585 stealing implementation) then simply inform the user with a warning
586 about possible click sounds and reduce the volume ramp down
587 appropriately instead of cancelling the audio device connection
588
589 Version 0.3.2 (24 June 2005)
590
591 * packaging changes:
592 - updated autotools build files to compile on OS X
593 (conditional compilation of CoreMIDI and MidiShare drivers)
594 - hand-crafted assembly optimization code can be disabled with
595 './configure --disable-asm' (definitely not recommended)
596 - fixed 'make dist' rule to include all necessary files
597 - require automake (>= 1.5) for 'make -f Makefile.cvs'
598 (due to 'dist-bzip2' automake option)
599
600 * Gigasampler format engine:
601 - support for the gig parameters for "release velocity response" curves
602 - fine tuning of the EGADSR envelope
603 - volume of release triggered samples now depends on note-on velocity,
604 note length and gig parameter "release trigger decay" instead of
605 note-off velocity.
606 - revised voice stealing
607 (fixes crash and endless loop caused by voice stealing)
608 - don't reset scale tuning on instrument or audio output device change
609 - handle key group conflicts right at the beginning of each fragment
610 instead of when the respective voice is actually launched
611 (fixes undefined behavior if stolen voices belonged to a key group -
612 this case was followed by a "killed voice survived" error message)
613 - fixed minor issue with null/silence samples
614 (those stole voices even though they don't need a voice at all which
615 resulted in "voice stealing didn't work out" messages)
616 - don't reset volume, pan, pitch and MIDI controller values on
617 instrument or audio output device change
618
619 * LSCP server:
620 - fixed some crashes (patch by Grigor Iliev, fixes #19)
621 - fixed LSCP event "CHANNEL_INFO" notification
622 (e.g. did not notify on volume changes or MIDI program change events)
623
624 * linuxsampler application:
625 - added command line parameters --lscp-addr and --lscp-port to override
626 default IP address and port of LSCP server
627
628 Version 0.3.1 (24 May 2005)
629
630 * initial release
