24 Version 1.0.0 (31 July 2009)
25
26 * packaging changes:
27 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
28 causing e.g. the libgig test to fail when
29 "./configure --disable-jack-driver" was used
30 (patch by Alexis Ballier)
31 - fixed compilation with gcc 4.3
32 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
33 - fixed configure so it detects x86_64 (#107)
34 - fixes for building with newer MinGW versions
35 - fix for building with bison 2.4 (#111)
36 - fixed building with libgig installed in a non-standard directory
37 - minor fix in configure for mmsystem.h detection on MinGW
38 - Windows: look for editor plugins and Fantasia using base
39 directory of liblinuxsampler dll (look in the same directory and one
40 directory above)
41 - configure script fix: removed unconditional use of SSE
42 - fixed building with sqlite installed in a non-standard directory
43 - when cross-compiling, don't try to create instruments.db
44 - fix for new mingw-w64 version, which has usleep
45
46 * general changes:
47 - bugfix: on some POSIX systems instrument editor plugins refused to
48 load as we used a non-portable Linux specific struct field
49 (fixes bug #70, patch by Ronald Baljeu)
50 - fixed endless loop which occured when loading an instrument editor
51 plugin DLL on Windows systems failed
52 - fixed memory leaks that occurred when liblinuxsampler was unloaded
53 - optimized the SynchronizedConfig class so it doesn't wait
54 unnecessarily long after an update
55 - added support for notifying instrument editors on note-on / note-off
56 events (e.g. to highlight the pressed keys on the virtual keyboard
57 of gigedit)
58 - added support for triggering notes by instrument editors (see above)
59 - be verbose on DLL load errors (on Linux)
60 - fixed di-harmonic triangle LFO implementation (this LFO implementation
61 is only used by very few systems, most pick the int math
62 implementation, which is usually faster)
63 - fixes for audio drivers with varying buffer sizes
64 - experimental support for running LinuxSampler as a DSSI, LV2 and
65 VST plugin
66 - notification events for stream/voice count statistics are now sent
67 only when there are actual changes
68 - added memory ordering constraints to improve stability on
69 multi-core and multi-cpu systems
70 - maximum voices and disk streams can now be altered at runtime
71 - fixed CPU feature detection on x86_64 (maybe fixes #108)
72 - automatic stacktrace mechanism is now turned off by default and can
73 be switched on by command line option "--stacktrace" (the automatic
74 stacktrace mechanism seems to be broken on most systems at the moment)
75 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
76 a pointer to the launched InstrumentEditor object
77 - added optional 3rd party user data parameter for following
78 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
79 InstrumentEditor::Launch(),
80 InstrumentManager::LaunchInstrumentEditor()
81 - theoretical fix: made SynchronizedConfig follow C++0x memory
82 model more strictly
83 - fixes for using large audio device buffers
84 - Windows: add the installation directory to the DLL search path
85 when loading an editor plugin (solves problems with VST and
86 gigedit on systems with other GTK versions installed)
87
88 * audio driver:
89 - removed the nonsense audio channel constraint (which was hard coded to
90 max. 100 audio channels) for most audio drivers
91 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
92 opposed to the LSCP specs
93 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
94 reflected the wrong value
95 - fixed a memory management bug in ASIO driver
96 - Makefile fix: JACK_CFLAGS wasn't used
97 - JACK: use jack_client_open instead of the deprecated
98 jack_client_new
99 - added (experimental) CoreAudio driver
100 - applied old fixes to the ASIO driver that were included in the
101 previous binary release but accidentally never committed to CVS
102 (fixes #117)
103 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
104 win64)
105 - VST: added support for sample rate and buffer size changes
106 - VST: close editor (Fantasia) when the VST is removed
107 - VST: avoid opening Fantasia more than once for each VST instance
108 - VST: export main function as "main" on Linux too (fix for
109 energyXT)
110 - VST: changed number of output channels from one stereo to 16
111 stereo
112 - added channel routing, fxsends and midi maps to the settings
113 stored in the plugin state
114 - performance optimization of AudioChannel::MixTo() and
115 AudioChannel::CopyTo() methods using GCC vector exensions
116 (if available)
117 - ASIO fixes: avoid initializing the device twice, avoid throwing
118 exception when getting parameters from a disconnected device
119
120 * MIDI driver:
121 - added JACK MIDI driver
122 - dispatch bank select as ordinary CC as well, the user might seriously
123 want to (mis)use it for some purpose ("fixed" in all current MIDI
124 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
125 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
126 CoreMidi or AU
127 - fixed mingw-w64 compilation error in MME driver
128 - made program change handling in MIDI thread real-time safe by
129 moving the logic to a non-RT thread
130 - fixed minor memory leak in ALSA driver
131
132 * instruments database:
133 - avoid time consuming samples scanning when adding instruments
134 to the instruments database
135 - added support for handling lost files in the instruments database
136 - Implemented option for adding instruments in separate directories
137 in the instruments database
138 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
139 - work-around for missing fnmatch function on Windows to make
140 instrument database compilable
141 - added instrument database support on Windows
142 works with both standalone mode and VST plugin.
143 the instruments DB file is located in
144 %USERPROFILE%\.linuxsampler\instruments.db which allows different
145 databases for each windows user
146 if no DB is present it automatically creates the .linuxsampler subdir
147 and then creates an empty DB
148 - fixed recursive import, which was broken on Windows
149
150 * Gigasampler format engine:
151 - fixed a memory leak that could happen when a channel was deleted
152 while notes were playing
153 - made it possible to load an instrument even if the audio thread
154 isn't running
155 - added partial support for the "Controller Triggered" MIDI rule,
156 enough for piano gigs with pedal noise samples
157 - minor fix: only mark FX sends as being modified if really the
158 respective FX send MIDI controller was used
159 - added support for GM global device volume SysEx message
160 (can be selected at compile time to either apply globally to the
161 whole sampler [default] or only to the sampler channels that are
162 connected to the respective MIDI input port the SysEx message arrived
163 on)
164 - bugfix: notes triggered at position 0 in the audio buffer were
165 sometimes wrongly killed in the same buffer, causing no sound to
166 be played
167 - added support for chromatic / drumkit mode Roland GS Sysex message
168 which is usally used to switch a part between chromatic sounds and
169 drumkit sounds (as opposed to their common default setting of MIDI
170 part 10 being a drumkit part and all other ones chromatic parts), in
171 LS however one can switch between the first 16 MIDI instrument maps
172 defined for the sampler
173 - made it possible to create multiple sample channels even if the
174 audio thread isn't running
175 - fixed crash when removing channel with active voices (#116)
176 - bugfix: on sample reference changes (instrument editor), only
177 un-cache the respective sample if it's really not used by any
178 sampler engine anymore
179 - re-cache samples in case they were changed by an instrument editor,
180 e.g. when a sample was added while playing (#82)
181 - fixed hanging notes which occured when note-off event had the exact
182 same time stamp as the voice's note-on event and occured both in the
183 same audio fragment cycle (fixes bug #112)
184 - added support for the "fine tune" and "pitch bend range"
185 instrument-level gig parameters
186 - fixed minor artifacts in pitch bend handling
187 - added support for GS Reset SysEx message
188 - allow gig files to use unlimited downward pitch shifting
189 - added a limit check for upward pitch shifting
190 - bugfix: sometimes, when playing a note twice fast, the second
191 note was silent
192 - fixed crash happening when a pitch bend event arrived at the
193 same time a new instrument was loading
194
195 * LSCP server:
196 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
197 react on MIDI data arriving on certain sampler channels (so far only
198 Note-On and Note-Off events are sent via this LSCP event)
199 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
200 react on MIDI data arriving on certain MIDI input devices (so far only
201 Note-On and Note-Off events are sent via this LSCP event)
202 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
203 SET DB_INSTRUMENT FILE_PATH
204 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
205 frontends to send MIDI messages to specific sampler channel
206 - added two additional fields to GET FILE INSTRUMENT INFO command -
207 KEY_BINDINGS and KEYSWITCH_BINDINGS
208 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
209 was incorrect
210 - Optimized the retrieval of the MIDI instrument mappings
211 - added new LSCP command "SET VOICES" to globally alter the maximum
212 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
213 be triggered respectively
214 - added new LSCP command "SET STREAMS" to globally alter the maximum
215 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
216 which will be triggered respectively
217 - bugfix: retry if "select" returns EINTR (this fixes a crash when
218 a gigedit file dialog is opened)
219 - close all connections when LSCPServer is deleted
220 - hard close of all sockets on exit
221 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
222 driver
223
224 * Bug fixes:
225 - fixed a crash which occurs when removing a sampler channel waiting
226 to start instrument loading after another channel
227 - fixed a crash which occurs when removing a sampler channel with
228 instrument loading in progress (bug #113)
229 - fixed termination caused by uncaught exception when adding MIDI
230 instrument with PERSISTENT load mode
231 - fixed possible iterator invalidations when resetting the sampler
232 - fixed memory leaks when issuing the following LSCP commands:
233 GET AUDIO_OUTPUT_DRIVER INFO
234 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
235 GET MIDI_INPUT_DRIVER INFO
236 GET MIDI_INPUT_DRIVER_PARAMETER INFO
237 - fixed possible compilation error when sqlite is not present
238 - fixed orphaned pointers when setting maximum voices limit (bug #118)
239 - fixed crash when changing the audio output device of a sampler
240 channel with loaded instrument and start playing notes
241 - fixed endless loop in Engine::SuspendAll() (bug #120)
242 - fixed a low-level atomic load function that was broken on 64-bit
243 PowerPC, which probably could cause crashes on that platform
244 - fixed a memory management error which could cause a crash when a
245 plugin was unloaded
246 - bugfix: two private structs had the same name, which could cause
247 problems if the linker chose the wrong constructor
248 - fixed low-level ConditionServer usage bug that caused lockups on
249 Windows
250
251
252 Version 0.5.1 (6 December 2007)
253
254 * packaging changes:
255 - added autoconf checks for pthread library
256 - added autoconf check for pthread bug found on certain NPTL-enabled
257 glibc versions (see Gentoo bug report #194076)
258 - added autoconf checks for MS Windows
259
260 * general changes:
261 - bugfix: the thread used by an editor plugin didn't die when the
262 editor closed
263 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
264 out all the space. operator--() did not apply size_mask after
265 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
266 order to avoid problems with the _NonVolatileReader functions.
267 - bugfix: Stream.h: added a missing divide by BytesPerSample in
268 GetWriteSpace(). Since this function is currently only used in
269 the stream's qsort() compare function, it didn't trigger any
270 bugs.
271 - Resampler.h, Synthesizer.h: cubic interpolation now works in
272 24bit mode too. Faster method to read 24bit words on little
273 endian machines (x86): replaced 3 byte reads + shifts with a 1
274 unaligned 32bit read and shift
275 - experimental support for MS Windows (MIDI input via MME, AUDIO
276 output via ASIO)
277 - made handling of SIGINT signal (Ctrl-C) a bit more robust
278 - support for monitoring the total number of active disk streams
279 (new LSCP commands: GET TOTAL_STREAM_COUNT,
280 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
281
282 * AUDIO driver:
283 - added Windows ASIO low latency audio driver
284
285 * MIDI driver:
286 - added MME Windows MIDI driver
287
288 * LSCP server:
289 - added support for Windows style path / filenames, however with
290 forward slash path separators instead of backslash
291 (i.e. "C:/foo/bar.gig")
292 - allow naughty liblscp to send non-string device parameters within
293 apostrophes as well
294 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
295 "LIST FILE INSTRUMENTS <file>" and
296 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
297 about an arbitrary instrument file on the system where the sampler is
298 running on
299
300 Version 0.5.0 (15 October 2007)
301
302 * packaging changes:
303 - config.h is not going to be installed along with liblinuxsampler's
304 API header files anymore
305 - only the API relevant header (and source) files will be exported to
306 the Doxygen API documentation (explicitly listed in Doxyfile.in)
307 - added completely new XCode project files for Mac OSX which is now
308 capable to execute our autoconf environment, thus no need anymore
309 to maintain the compile time configuration file (osx/version.h) for
310 OSX manually (patch by Toshi Nagata)
311 - fixed buggy boolean --enable-foo / --disable-foo configure script
312 parameters
313 - global.h now only covers global definitions that are needed for the
314 C++ API header files, all implementation internal global definitions
315 are now in global_private.h
316 - atomic.h is not exposed to the C++ API anymore
317 - no need to include config.h anymore for using LS's API header files
318 - fixed warnings in API doc generation
319
320 * general changes:
321 - replaced the old, confusing MIDI program change mechanism by a
322 flexible MIDI instrument mapper which allows to map arbitrary
323 (MIDI bank, MIDI program) pairs with arbitrary
324 (engine type, instrument file, file index) triplets which will be
325 loaded on the respective channel when such MIDI program change
326 messages arrive, beside that, each entry allows to define a life-time
327 strategy for the instrument, so the user can define whether the
328 instrument should i.e. be permanently loaded (to be able to switch
329 quickly among sounds) or i.e. loaded just on demand when the
330 respective program change arrives (to safe RAM space), as well as a
331 global volume factor for each entry, so the user can adjust the volume
332 dynamic of his mapped instrument collection without having to modify
333 the instrument files, also one can manage arbitrary amount of such
334 MIDI instrument maps and assign each sampler channel individually
335 a certain map, so that i.e. separation of normal instruments and
336 drumkits is possible
337 - new notification events for tracking changes to audio/MIDI devices,
338 MIDI instrument maps, MIDI instruments, FX sends, global volume.
339 - sampler was limited to load max. 200 instruments in the background
340 due to a constant size RingBuffer FIFO which is now replaced by a
341 dynamic (unlimited) size std::list FIFO
342 - added FX sends, these allow to route audio signals to arbitrary audio
343 output channels for being processed by external effect processors
344 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
345 controllers
346 - global (sampler wide) volume can now be controlled at runtime
347 - Implemented new, improved notification system
348 - fixed compilation errors regarding OSX
349 (patch by Toshi Nagata)
350 - implemented instruments database
351 - added support for escape sequences to the instruments database
352 - added highly experimental support for on-the-fly instrument editing
353 within the sampler's process (by using instrument editor plugins),
354 you'll notice the new "Registered instrument editors:" message on
355 startup, added a new LSCP command:
356 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
357 to spawn a matching instrument editor for the instrument on the
358 given sampler channel, the plugin path can be overridden at compile
359 time with ./configure --enable-plugin-dir=/some/dir
360 - added experimental code for synchronizing instrument editors hosted
361 in the sampler's process to safely edit instruments while playing
362 without a crash (hopefully) by either suspending single regions
363 wherever possible or if unavoidable whole engine(s)
364 - fixed several issues in fundamental "Thread" class: set scheduling
365 policy and priority on thread level, set a minimum stack size for
366 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
367 threads simply inherited properties of starting thread instead of
368 setting their own policy and priority
369 - minor fix in our automatic stack trace mechanism on crashes, the
370 main process did not wait for the stack trace process to finish
371 its output
372 - fixed some minor memory leaks
373 - reenabled assembly features support, at the moment only for
374 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
375 - minor assembly fix in x86 features detection (don't use the PIC
376 register, to avoid relocations in the text segment at runtime)
377 - POSIX callback functions of Thread.h are hidden
378
379 * MIDI driver:
380 - dispatch bank select (MSB and LSB) messages
381
382 * audio driver:
383 - the ALSA audio output driver parameters now reflect the correct
384 parameter value ranges for the respective selected sound card
385 (patch by Till Wimmer, a bit fixed and extended)
386
387 * Gigasampler format engine:
388 - if a filter is used and EG2 finishes before EG1, let the voice
389 die when EG2 has finished (this fixes a problem with clicks and
390 voice starvation for some gigs)
391 - playback is no longer disabled during instrument loading
392 - all notes playing on a channel that changes its instrument keep
393 playing with the old instrument until they get a note off
394 command
395 - EG fix: a release value of zero could cause noises or crash
396 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
397 - EG fine tuning: when attack is zero the EG starts at a level
398 above max sustain level, which means that there is a decay phase
399 even if sustain is 100%
400 - more EG fixes: the level could sometimes go below zero and cause
401 noises or crashes
402 - minor fix of EGDecay (patch by Toshi Nagata)
403 - fixed compiler error when --enable-override-filter-type was
404 supplied to the configure script (fixes #46)
405 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
406 instead of a fix value
407 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
408 127 (solo mode) only kill voices if the respective mode really
409 changed
410
411 * LSCP server:
412 - fixed compile time error for old Bison versions
413 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
414 - parser now supports extended ASCII character set
415 (up to ASCII code 255, i.e. includes now umlauts and accents)
416 - filename arguments in LSCP commands now allow to use escape
417 sequences, that is directly literal as one of: \', \", \\, \n, \r,
418 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
419 code value like \xf2) (fixes bug #24)
420 - the following LSCP commands now also support escape sequences for at
421 least one of their text-based parameters (i.e. name, description):
422 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
423 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
424 "SET DB_INSTRUMENT_DIRECTORY NAME",
425 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
426 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
427 "FIND DB_INSTRUMENT_DIRECTORIES"
428 - returns verbose syntax errors (line and column where syntax error
429 occured, the unexpected character and the actually expected, possible
430 character(s), the latter only if less than 5 possibilities)
431 - made sure that LSCP syntax is not affected by gigedit locale
432 settings
433 - bugfix regarding strings parameter lists: all comma separated lists
434 of strings were treated as being one string containing commas
435 (fixes #57)
436
437 * Bug fixes:
438 - fixed crash occurring on certain LSCP scripts (Bug 39)
439 - another thread safety fix for lscp "load engine" and "set
440 channel audio output device"
441 - fixed a crash which occurs when reassigning the same engine
442 on a sampler channel with connected MIDI device
443 - fixed a crash which occurs when changing the number of ports of a MIDI
444 device connected to a sampler channel to number less then or equal
445 to the index of the port to which the sampler channel is connected.
446 - The previous bindings were not been disconnected when altering
447 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
448 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
449 - The active stream/voice count statistic was incorrect.
450 - notification events were not been sent for some sampler
451 channel changes
452 - added default min and max values to restrict the number of allowed
453 audio output channels and MIDI input ports
454 - the connection to the PCM interface is now closed when destroying
455 an audio output device
456 - files with slash in their path or filename could not be loaded
457
458 * test cases:
459 - updated and fixed (haven't been touched in a while)
460
461 Version 0.4.0 (24 November 2006)
462
463 * packaging changes:
464 - changed deprecated copyright attribute to license; added ldconfig
465 to post-(un)install steps; added devel package for liblinuxsampler;
466 to linuxsampler.spec (RPM)
467 - install necessary development header files for allowing 3rd party
468 applications to link against liblinuxsampler
469 - liblinuxsampler's API documentation can be generated with 'make docs'
470 (Doxygen required)
471 - added benchmark to automatically detect the best triangle LFO
472 implementation (currently either an integer math solution or a
473 di-harmonic approximation), automatic detection can be overriden
474 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
475 configure script argument though (mandatory for cross-compilation)
476 - do not automatically pick optimized gcc flags if the user already
477 provided some on his own (as CXXFLAGS)
478 - added compile time option to disable processing of All-Notes-Off MIDI
479 messages
480 - added compile time options to allow disabling the various audio and
481 MIDI drivers
482 - fixed automatic GCC CPU switch detection on PPC
483 (patch by Ebrahim Mayat)
484
485 * Gigasampler format engine:
486 - extensive synthesis optimization
487 (reimplementation of EGs and LFO(s), removed synthesis parameter
488 prerendering and the synthesis parameter matrix in general, splitting
489 each audio fragment into subfragments now where each subfragment uses
490 constant pitch and filter coefficients. The volume coefficient is
491 linearly interpolated inside a subfragment, unless
492 --disable-interpolate-volume is set.)
493 - fine tuning of the EG modulation parameters
494 - improved filter cutoff calculation by adding support for the
495 following gig parameters: Cutoff freq (used when no cutoff
496 controller is defined), Control invert, Minimum cutoff, Velocity
497 curve and Velocity range. The keyboard tracking now scales
498 cutoff frequency instead of resonance.
499 - added support for gig parameter Resonance.
500 - fixed bug in sysex handling (patch by Juan Linietsky)
501 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
502 which can be overridden with --enable-global-attenuation
503 - EG fixes: made the length of "attack hold" stage more
504 accurate. Release stage can now start before attack stage
505 ends. Cancel release didn't work when sustain was zero. Attack
506 time now has a minimal value to prevent clicks.
507 - fixed pitch changes larger than one octave
508 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
509 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
510 all modes can be altered via standard GM messages, that is CC5 for
511 altering portamento time, CC65 for enabling / disabling portamento
512 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
513 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
514 parameter) and crossfade
515 - added support for the "attenuation controller threshold" gig
516 parameter
517 - added smoothing of volume changes caused by control change
518 messages
519 - sample loop parameters are now taken from the DimensionRegion
520 instead of the wave chunk
521 - fixed keyswitching for v3 gigs with a number of keyswitch splits
522 not equal to a power of two
523 - reimplementation of the filter algorithm. The new filter is more
524 accurate and supports all gig filter types, including bandreject
525 and lowpass turbo.
526 - real support for 24 bit samples - samples are not truncated to
527 16 bits anymore
528 - support for aftertouch (channel pressure, not polyphonic
529 aftertouch)
530 - LFO1 behaviour fixed (dampening from max volume instead of
531 amplifying from 0)
532
533 * LSCP server:
534 - fixed application exit on broken pipe error (fixes bug #20)
535 - fixed the notification messages delay due to lack of
536 network activity (fixes bug #26)
537 - fixed parser bug which occured on space(s) within device parameters
538 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
539
540 * audio driver:
541 - added aRts audio output driver (by no means RT safe)
542
543 * MIDI driver:
544 - fixed legacy sysex code which caused dispatching of MIDI SysEx
545 messages several times instead of once
546 - API extension for MIDI drivers which already supply exact time stamps
547 for events (i.e. for offline rendering based MIDI drivers)
548 - added checks for bad MIDI data
549
550 * linuxsampler application:
551 - show available sampler engine types on startup
552
553 * general changes:
554 - support for muting sampler channels and solo mode of the same, two new
555 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
556 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
557 introduced for this, the behavior is the same like on a mixer console
558 (patch by Grigor Iliev, a bit adjusted). Also added configure option
559 --enable-process-muted-channels which can be used to enable the
560 processing of muted channels.
561 - support for sostenuto pedal
562 - support for monitoring the total number of active voices
563 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
564 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
565 - fixed some memory management errors
566 - fixed some concurrency problems that could lead to crashes when
567 LSCP commands were executed
568 - fixed crash when instrument loading failed previously on the same
569 sampler channel (fixes bug #36)
570
571 Version 0.3.3 (15 July 2005)
572
573 * packaging changes:
574 - fixed compilation with gcc 4.0
575
576 * Gigasampler format engine:
577 - LFO preprocessing was performed even though the respective LFO was
578 disabled by the instrument patch (minor efficiency fix)
579 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
580 for volume ramp downs in the same fragment (needed for current voice
581 stealing implementation) then simply inform the user with a warning
582 about possible click sounds and reduce the volume ramp down
583 appropriately instead of cancelling the audio device connection
584
585 Version 0.3.2 (24 June 2005)
586
587 * packaging changes:
588 - updated autotools build files to compile on OS X
589 (conditional compilation of CoreMIDI and MidiShare drivers)
590 - hand-crafted assembly optimization code can be disabled with
591 './configure --disable-asm' (definitely not recommended)
592 - fixed 'make dist' rule to include all necessary files
593 - require automake (>= 1.5) for 'make -f Makefile.cvs'
594 (due to 'dist-bzip2' automake option)
595
596 * Gigasampler format engine:
597 - support for the gig parameters for "release velocity response" curves
598 - fine tuning of the EGADSR envelope
599 - volume of release triggered samples now depends on note-on velocity,
600 note length and gig parameter "release trigger decay" instead of
601 note-off velocity.
602 - revised voice stealing
603 (fixes crash and endless loop caused by voice stealing)
604 - don't reset scale tuning on instrument or audio output device change
605 - handle key group conflicts right at the beginning of each fragment
606 instead of when the respective voice is actually launched
607 (fixes undefined behavior if stolen voices belonged to a key group -
608 this case was followed by a "killed voice survived" error message)
609 - fixed minor issue with null/silence samples
610 (those stole voices even though they don't need a voice at all which
611 resulted in "voice stealing didn't work out" messages)
612 - don't reset volume, pan, pitch and MIDI controller values on
613 instrument or audio output device change
614
615 * LSCP server:
616 - fixed some crashes (patch by Grigor Iliev, fixes #19)
617 - fixed LSCP event "CHANNEL_INFO" notification
618 (e.g. did not notify on volume changes or MIDI program change events)
619
620 * linuxsampler application:
621 - added command line parameters --lscp-addr and --lscp-port to override
622 default IP address and port of LSCP server
623
624 Version 0.3.1 (24 May 2005)
625
626 * initial release
