10 - made sure all source files for hostplugins are included when
11 doing "make dist"
12 - removed empty directories left from the cvs to svn migration

16 - minor Makefile fix for building lscpparser when build and source
17 directories are separate
18 - Mac OS X: made it possible to specify plugin installation dir to
19 configure
20 - Mac OS X: Makefile fix for the install-strip target
22 * general changes:
23 - Refactoring: moved the independent code from
24 the Gigasampler format engine to base classes
25 - command line option '--profile' is currently disabled, since the
26 respective profiling code is currently broken

36 effect type is)
37 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
38 note (in this implementation of the sampler its simply hard routed to

138 - Listen to all interfaces on Mac OS X (INADDR_ANY)
139 - VST bugfix: If the host called resume() before and after
140 changing sample rate or block size, the number of channels was
141 incorrectly set to two. This caused silence in Cubase 5.
142 - save engine type (gig, sfz or sf2) in plugin state
143 - VST: when opening Fantasia, look for both 32 and 64 bit Java on
144 64 bit Windows

148 - AU: link AU plugin dynamically if --disable-shared isn't
149 specified
151 * MIDI driver:
152 - ALSA MIDI driver supports now "NAME" device parameter, for overriding
153 the ALSA sequencer client name
154 - removed limit of maximum amount of MIDI ports per MIDI device, since
155 there is no reason for this limit
157 * audio driver:

197 * Bug fixes:
198 - Fixed crash which may occur when MIDI key + transpose is out of range
199 - minor valgrind fixes
200 - fixed crash which occurred when changing an already deployed sampler
201 channel to a different engine type
202 - fixed crash when deleting a sampler channel or changing engine
203 type while an instrument load was in progress
204 - bugfix: playing a note while changing the instrument could cause
205 a crash, or give "Handing back unknown region" error messages
206 - bugfix: calling SET VOICES (which Fantasia does on start and
207 refresh) could cause instruments to be unloaded
208 - Mac OS X: fixed name collision of enum in EffectControl and
209 wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
210 - Mac OS X: fixed hanging threads
211 - Windows: disabled the previous thread fix on non-Mac systems, as
212 it caused hanging threads on Windows

214 after MIDI/audio device creation failure
216 Version 1.0.0 (31 July 2009)
218 * packaging changes:
219 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
220 causing e.g. the libgig test to fail when
221 "./configure --disable-jack-driver" was used
222 (patch by Alexis Ballier)
223 - fixed compilation with gcc 4.3
224 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
225 - fixed configure so it detects x86_64 (#107)
226 - fixes for building with newer MinGW versions
227 - fix for building with bison 2.4 (#111)
228 - fixed building with libgig installed in a non-standard directory
229 - minor fix in configure for mmsystem.h detection on MinGW
230 - Windows: look for editor plugins and Fantasia using base
231 directory of liblinuxsampler dll (look in the same directory and one
232 directory above)
233 - configure script fix: removed unconditional use of SSE
234 - fixed building with sqlite installed in a non-standard directory
235 - when cross-compiling, don't try to create instruments.db
236 - fix for new mingw-w64 version, which has usleep
238 * general changes:
239 - bugfix: on some POSIX systems instrument editor plugins refused to
240 load as we used a non-portable Linux specific struct field
241 (fixes bug #70, patch by Ronald Baljeu)
242 - fixed endless loop which occured when loading an instrument editor
243 plugin DLL on Windows systems failed
244 - fixed memory leaks that occurred when liblinuxsampler was unloaded
245 - optimized the SynchronizedConfig class so it doesn't wait
246 unnecessarily long after an update
247 - added support for notifying instrument editors on note-on / note-off
248 events (e.g. to highlight the pressed keys on the virtual keyboard
249 of gigedit)
250 - added support for triggering notes by instrument editors (see above)
251 - be verbose on DLL load errors (on Linux)
252 - fixed di-harmonic triangle LFO implementation (this LFO implementation
253 is only used by very few systems, most pick the int math
254 implementation, which is usually faster)
255 - fixes for audio drivers with varying buffer sizes
256 - experimental support for running LinuxSampler as a DSSI, LV2 and
257 VST plugin
258 - notification events for stream/voice count statistics are now sent
259 only when there are actual changes
260 - added memory ordering constraints to improve stability on
261 multi-core and multi-cpu systems
262 - maximum voices and disk streams can now be altered at runtime
263 - fixed CPU feature detection on x86_64 (maybe fixes #108)
264 - automatic stacktrace mechanism is now turned off by default and can
265 be switched on by command line option "--stacktrace" (the automatic
266 stacktrace mechanism seems to be broken on most systems at the moment)
267 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
268 a pointer to the launched InstrumentEditor object
269 - added optional 3rd party user data parameter for following
270 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
271 InstrumentEditor::Launch(),
272 InstrumentManager::LaunchInstrumentEditor()
273 - theoretical fix: made SynchronizedConfig follow C++0x memory
274 model more strictly
275 - fixes for using large audio device buffers
276 - Windows: add the installation directory to the DLL search path
277 when loading an editor plugin (solves problems with VST and
278 gigedit on systems with other GTK versions installed)
280 * audio driver:
281 - removed the nonsense audio channel constraint (which was hard coded to
282 max. 100 audio channels) for most audio drivers
283 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
284 opposed to the LSCP specs
285 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
286 reflected the wrong value
287 - fixed a memory management bug in ASIO driver
288 - Makefile fix: JACK_CFLAGS wasn't used
289 - JACK: use jack_client_open instead of the deprecated
290 jack_client_new
291 - added (experimental) CoreAudio driver
292 - applied old fixes to the ASIO driver that were included in the
293 previous binary release but accidentally never committed to CVS
294 (fixes #117)
295 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
296 win64)
297 - VST: added support for sample rate and buffer size changes
298 - VST: close editor (Fantasia) when the VST is removed
299 - VST: avoid opening Fantasia more than once for each VST instance
300 - VST: export main function as "main" on Linux too (fix for
301 energyXT)
302 - VST: changed number of output channels from one stereo to 16
303 stereo
304 - added channel routing, fxsends and midi maps to the settings
305 stored in the plugin state
306 - performance optimization of AudioChannel::MixTo() and
307 AudioChannel::CopyTo() methods using GCC vector exensions
308 (if available)
309 - ASIO fixes: avoid initializing the device twice, avoid throwing
310 exception when getting parameters from a disconnected device
312 * MIDI driver:
313 - added JACK MIDI driver
314 - dispatch bank select as ordinary CC as well, the user might seriously
315 want to (mis)use it for some purpose ("fixed" in all current MIDI
316 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
317 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
318 CoreMidi or AU
319 - fixed mingw-w64 compilation error in MME driver
320 - made program change handling in MIDI thread real-time safe by
321 moving the logic to a non-RT thread
322 - fixed minor memory leak in ALSA driver
324 * instruments database:
325 - avoid time consuming samples scanning when adding instruments
326 to the instruments database
327 - added support for handling lost files in the instruments database
328 - Implemented option for adding instruments in separate directories
329 in the instruments database
330 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
331 - work-around for missing fnmatch function on Windows to make
332 instrument database compilable
333 - added instrument database support on Windows
334 works with both standalone mode and VST plugin.
335 the instruments DB file is located in
336 %USERPROFILE%\.linuxsampler\instruments.db which allows different
337 databases for each windows user
338 if no DB is present it automatically creates the .linuxsampler subdir
339 and then creates an empty DB
340 - fixed recursive import, which was broken on Windows
342 * Gigasampler format engine:
343 - fixed a memory leak that could happen when a channel was deleted
344 while notes were playing
345 - made it possible to load an instrument even if the audio thread
346 isn't running
347 - added partial support for the "Controller Triggered" MIDI rule,
348 enough for piano gigs with pedal noise samples
349 - minor fix: only mark FX sends as being modified if really the
350 respective FX send MIDI controller was used
351 - added support for GM global device volume SysEx message
352 (can be selected at compile time to either apply globally to the
353 whole sampler [default] or only to the sampler channels that are
354 connected to the respective MIDI input port the SysEx message arrived
355 on)
356 - bugfix: notes triggered at position 0 in the audio buffer were
357 sometimes wrongly killed in the same buffer, causing no sound to
358 be played
359 - added support for chromatic / drumkit mode Roland GS Sysex message
360 which is usally used to switch a part between chromatic sounds and
361 drumkit sounds (as opposed to their common default setting of MIDI
362 part 10 being a drumkit part and all other ones chromatic parts), in
363 LS however one can switch between the first 16 MIDI instrument maps
364 defined for the sampler
365 - made it possible to create multiple sample channels even if the
366 audio thread isn't running
367 - fixed crash when removing channel with active voices (#116)
368 - bugfix: on sample reference changes (instrument editor), only
369 un-cache the respective sample if it's really not used by any
370 sampler engine anymore
371 - re-cache samples in case they were changed by an instrument editor,
372 e.g. when a sample was added while playing (#82)
373 - fixed hanging notes which occured when note-off event had the exact
374 same time stamp as the voice's note-on event and occured both in the
375 same audio fragment cycle (fixes bug #112)
376 - added support for the "fine tune" and "pitch bend range"
377 instrument-level gig parameters
378 - fixed minor artifacts in pitch bend handling
379 - added support for GS Reset SysEx message
380 - allow gig files to use unlimited downward pitch shifting
381 - added a limit check for upward pitch shifting
382 - bugfix: sometimes, when playing a note twice fast, the second
383 note was silent
384 - fixed crash happening when a pitch bend event arrived at the
385 same time a new instrument was loading
387 * LSCP server:
388 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
389 react on MIDI data arriving on certain sampler channels (so far only
390 Note-On and Note-Off events are sent via this LSCP event)
391 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
392 react on MIDI data arriving on certain MIDI input devices (so far only
393 Note-On and Note-Off events are sent via this LSCP event)
394 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
396 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
397 frontends to send MIDI messages to specific sampler channel
398 - added two additional fields to GET FILE INSTRUMENT INFO command -
400 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
401 was incorrect
402 - Optimized the retrieval of the MIDI instrument mappings
403 - added new LSCP command "SET VOICES" to globally alter the maximum
404 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
405 be triggered respectively
406 - added new LSCP command "SET STREAMS" to globally alter the maximum
407 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
408 which will be triggered respectively
409 - bugfix: retry if "select" returns EINTR (this fixes a crash when
410 a gigedit file dialog is opened)
411 - close all connections when LSCPServer is deleted
412 - hard close of all sockets on exit
413 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
414 driver
416 * Bug fixes:
417 - fixed a crash which occurs when removing a sampler channel waiting
418 to start instrument loading after another channel
419 - fixed a crash which occurs when removing a sampler channel with
420 instrument loading in progress (bug #113)
421 - fixed termination caused by uncaught exception when adding MIDI
422 instrument with PERSISTENT load mode
423 - fixed possible iterator invalidations when resetting the sampler
424 - fixed memory leaks when issuing the following LSCP commands:
429 - fixed possible compilation error when sqlite is not present
430 - fixed orphaned pointers when setting maximum voices limit (bug #118)
431 - fixed crash when changing the audio output device of a sampler
432 channel with loaded instrument and start playing notes
433 - fixed endless loop in Engine::SuspendAll() (bug #120)
434 - fixed a low-level atomic load function that was broken on 64-bit
435 PowerPC, which probably could cause crashes on that platform
436 - fixed a memory management error which could cause a crash when a
437 plugin was unloaded
438 - bugfix: two private structs had the same name, which could cause
439 problems if the linker chose the wrong constructor
440 - fixed low-level ConditionServer usage bug that caused lockups on
441 Windows
444 Version 0.5.1 (6 December 2007)
446 * packaging changes:
447 - added autoconf checks for pthread library
448 - added autoconf check for pthread bug found on certain NPTL-enabled
449 glibc versions (see Gentoo bug report #194076)
450 - added autoconf checks for MS Windows
452 * general changes:
453 - bugfix: the thread used by an editor plugin didn't die when the
454 editor closed
455 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
456 out all the space. operator--() did not apply size_mask after
457 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
458 order to avoid problems with the _NonVolatileReader functions.
459 - bugfix: Stream.h: added a missing divide by BytesPerSample in
460 GetWriteSpace(). Since this function is currently only used in
461 the stream's qsort() compare function, it didn't trigger any
462 bugs.
463 - Resampler.h, Synthesizer.h: cubic interpolation now works in
464 24bit mode too. Faster method to read 24bit words on little
465 endian machines (x86): replaced 3 byte reads + shifts with a 1
466 unaligned 32bit read and shift
467 - experimental support for MS Windows (MIDI input via MME, AUDIO
468 output via ASIO)
469 - made handling of SIGINT signal (Ctrl-C) a bit more robust
470 - support for monitoring the total number of active disk streams
471 (new LSCP commands: GET TOTAL_STREAM_COUNT,
474 * AUDIO driver:
475 - added Windows ASIO low latency audio driver
477 * MIDI driver:
478 - added MME Windows MIDI driver
480 * LSCP server:
481 - added support for Windows style path / filenames, however with
482 forward slash path separators instead of backslash
483 (i.e. "C:/foo/bar.gig")
484 - allow naughty liblscp to send non-string device parameters within
485 apostrophes as well
486 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
487 "LIST FILE INSTRUMENTS <file>" and
488 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
489 about an arbitrary instrument file on the system where the sampler is
490 running on
492 Version 0.5.0 (15 October 2007)
494 * packaging changes:
495 - config.h is not going to be installed along with liblinuxsampler's
496 API header files anymore
497 - only the API relevant header (and source) files will be exported to
498 the Doxygen API documentation (explicitly listed in Doxyfile.in)
499 - added completely new XCode project files for Mac OSX which is now
500 capable to execute our autoconf environment, thus no need anymore
501 to maintain the compile time configuration file (osx/version.h) for
502 OSX manually (patch by Toshi Nagata)
503 - fixed buggy boolean --enable-foo / --disable-foo configure script
504 parameters
505 - global.h now only covers global definitions that are needed for the
506 C++ API header files, all implementation internal global definitions
507 are now in global_private.h
508 - atomic.h is not exposed to the C++ API anymore
509 - no need to include config.h anymore for using LS's API header files
510 - fixed warnings in API doc generation
512 * general changes:
513 - replaced the old, confusing MIDI program change mechanism by a
514 flexible MIDI instrument mapper which allows to map arbitrary
515 (MIDI bank, MIDI program) pairs with arbitrary
516 (engine type, instrument file, file index) triplets which will be
517 loaded on the respective channel when such MIDI program change
518 messages arrive, beside that, each entry allows to define a life-time
519 strategy for the instrument, so the user can define whether the
520 instrument should i.e. be permanently loaded (to be able to switch
521 quickly among sounds) or i.e. loaded just on demand when the
522 respective program change arrives (to safe RAM space), as well as a
523 global volume factor for each entry, so the user can adjust the volume
524 dynamic of his mapped instrument collection without having to modify
525 the instrument files, also one can manage arbitrary amount of such
526 MIDI instrument maps and assign each sampler channel individually
527 a certain map, so that i.e. separation of normal instruments and
528 drumkits is possible
529 - new notification events for tracking changes to audio/MIDI devices,
530 MIDI instrument maps, MIDI instruments, FX sends, global volume.
531 - sampler was limited to load max. 200 instruments in the background
532 due to a constant size RingBuffer FIFO which is now replaced by a
533 dynamic (unlimited) size std::list FIFO
534 - added FX sends, these allow to route audio signals to arbitrary audio
535 output channels for being processed by external effect processors
536 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
537 controllers
538 - global (sampler wide) volume can now be controlled at runtime
539 - Implemented new, improved notification system
540 - fixed compilation errors regarding OSX
541 (patch by Toshi Nagata)
542 - implemented instruments database
543 - added support for escape sequences to the instruments database
544 - added highly experimental support for on-the-fly instrument editing
545 within the sampler's process (by using instrument editor plugins),
546 you'll notice the new "Registered instrument editors:" message on
547 startup, added a new LSCP command:
548 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
549 to spawn a matching instrument editor for the instrument on the
550 given sampler channel, the plugin path can be overridden at compile
551 time with ./configure --enable-plugin-dir=/some/dir
552 - added experimental code for synchronizing instrument editors hosted
553 in the sampler's process to safely edit instruments while playing
554 without a crash (hopefully) by either suspending single regions
555 wherever possible or if unavoidable whole engine(s)
556 - fixed several issues in fundamental "Thread" class: set scheduling
557 policy and priority on thread level, set a minimum stack size for
558 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
559 threads simply inherited properties of starting thread instead of
560 setting their own policy and priority
561 - minor fix in our automatic stack trace mechanism on crashes, the
562 main process did not wait for the stack trace process to finish
563 its output
564 - fixed some minor memory leaks
565 - reenabled assembly features support, at the moment only for
566 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
567 - minor assembly fix in x86 features detection (don't use the PIC
568 register, to avoid relocations in the text segment at runtime)
569 - POSIX callback functions of Thread.h are hidden
571 * MIDI driver:
572 - dispatch bank select (MSB and LSB) messages
574 * audio driver:
575 - the ALSA audio output driver parameters now reflect the correct
576 parameter value ranges for the respective selected sound card
577 (patch by Till Wimmer, a bit fixed and extended)
579 * Gigasampler format engine:
580 - if a filter is used and EG2 finishes before EG1, let the voice
581 die when EG2 has finished (this fixes a problem with clicks and
582 voice starvation for some gigs)
583 - playback is no longer disabled during instrument loading
584 - all notes playing on a channel that changes its instrument keep
585 playing with the old instrument until they get a note off
586 command
587 - EG fix: a release value of zero could cause noises or crash
588 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
589 - EG fine tuning: when attack is zero the EG starts at a level
590 above max sustain level, which means that there is a decay phase
591 even if sustain is 100%
592 - more EG fixes: the level could sometimes go below zero and cause
593 noises or crashes
594 - minor fix of EGDecay (patch by Toshi Nagata)
595 - fixed compiler error when --enable-override-filter-type was
596 supplied to the configure script (fixes #46)
597 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
598 instead of a fix value
599 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
600 127 (solo mode) only kill voices if the respective mode really
601 changed
603 * LSCP server:
604 - fixed compile time error for old Bison versions
605 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
606 - parser now supports extended ASCII character set
607 (up to ASCII code 255, i.e. includes now umlauts and accents)
608 - filename arguments in LSCP commands now allow to use escape
609 sequences, that is directly literal as one of: \', \", \\, \n, \r,
610 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
611 code value like \xf2) (fixes bug #24)
612 - the following LSCP commands now also support escape sequences for at
613 least one of their text-based parameters (i.e. name, description):
620 - returns verbose syntax errors (line and column where syntax error
621 occured, the unexpected character and the actually expected, possible
622 character(s), the latter only if less than 5 possibilities)
623 - made sure that LSCP syntax is not affected by gigedit locale
624 settings
625 - bugfix regarding strings parameter lists: all comma separated lists
626 of strings were treated as being one string containing commas
627 (fixes #57)
629 * Bug fixes:
630 - fixed crash occurring on certain LSCP scripts (Bug 39)
631 - another thread safety fix for lscp "load engine" and "set
632 channel audio output device"
633 - fixed a crash which occurs when reassigning the same engine
634 on a sampler channel with connected MIDI device
635 - fixed a crash which occurs when changing the number of ports of a MIDI
636 device connected to a sampler channel to number less then or equal
637 to the index of the port to which the sampler channel is connected.
638 - The previous bindings were not been disconnected when altering
639 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
640 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
641 - The active stream/voice count statistic was incorrect.
642 - notification events were not been sent for some sampler
643 channel changes
644 - added default min and max values to restrict the number of allowed
645 audio output channels and MIDI input ports
646 - the connection to the PCM interface is now closed when destroying
647 an audio output device
648 - files with slash in their path or filename could not be loaded
650 * test cases:
651 - updated and fixed (haven't been touched in a while)
653 Version 0.4.0 (24 November 2006)
655 * packaging changes:
656 - changed deprecated copyright attribute to license; added ldconfig
657 to post-(un)install steps; added devel package for liblinuxsampler;
658 to linuxsampler.spec (RPM)
659 - install necessary development header files for allowing 3rd party
660 applications to link against liblinuxsampler
661 - liblinuxsampler's API documentation can be generated with 'make docs'
662 (Doxygen required)
663 - added benchmark to automatically detect the best triangle LFO
664 implementation (currently either an integer math solution or a
665 di-harmonic approximation), automatic detection can be overriden
666 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
667 configure script argument though (mandatory for cross-compilation)
668 - do not automatically pick optimized gcc flags if the user already
669 provided some on his own (as CXXFLAGS)
670 - added compile time option to disable processing of All-Notes-Off MIDI
671 messages
672 - added compile time options to allow disabling the various audio and
673 MIDI drivers
674 - fixed automatic GCC CPU switch detection on PPC
675 (patch by Ebrahim Mayat)
677 * Gigasampler format engine:
678 - extensive synthesis optimization
679 (reimplementation of EGs and LFO(s), removed synthesis parameter
680 prerendering and the synthesis parameter matrix in general, splitting
681 each audio fragment into subfragments now where each subfragment uses
682 constant pitch and filter coefficients. The volume coefficient is
683 linearly interpolated inside a subfragment, unless
684 --disable-interpolate-volume is set.)
685 - fine tuning of the EG modulation parameters
686 - improved filter cutoff calculation by adding support for the
687 following gig parameters: Cutoff freq (used when no cutoff
688 controller is defined), Control invert, Minimum cutoff, Velocity
689 curve and Velocity range. The keyboard tracking now scales
690 cutoff frequency instead of resonance.
691 - added support for gig parameter Resonance.
692 - fixed bug in sysex handling (patch by Juan Linietsky)
693 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
694 which can be overridden with --enable-global-attenuation
695 - EG fixes: made the length of "attack hold" stage more
696 accurate. Release stage can now start before attack stage
697 ends. Cancel release didn't work when sustain was zero. Attack
698 time now has a minimal value to prevent clicks.
699 - fixed pitch changes larger than one octave
700 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
701 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
702 all modes can be altered via standard GM messages, that is CC5 for
703 altering portamento time, CC65 for enabling / disabling portamento
704 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
705 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
706 parameter) and crossfade
707 - added support for the "attenuation controller threshold" gig
708 parameter
709 - added smoothing of volume changes caused by control change
710 messages
711 - sample loop parameters are now taken from the DimensionRegion
712 instead of the wave chunk
713 - fixed keyswitching for v3 gigs with a number of keyswitch splits
714 not equal to a power of two
715 - reimplementation of the filter algorithm. The new filter is more
716 accurate and supports all gig filter types, including bandreject
717 and lowpass turbo.
718 - real support for 24 bit samples - samples are not truncated to
719 16 bits anymore
720 - support for aftertouch (channel pressure, not polyphonic
721 aftertouch)
722 - LFO1 behaviour fixed (dampening from max volume instead of
723 amplifying from 0)
725 * LSCP server:
726 - fixed application exit on broken pipe error (fixes bug #20)
727 - fixed the notification messages delay due to lack of
728 network activity (fixes bug #26)
729 - fixed parser bug which occured on space(s) within device parameters
732 * audio driver:
733 - added aRts audio output driver (by no means RT safe)
735 * MIDI driver:
736 - fixed legacy sysex code which caused dispatching of MIDI SysEx
737 messages several times instead of once
738 - API extension for MIDI drivers which already supply exact time stamps
739 for events (i.e. for offline rendering based MIDI drivers)
740 - added checks for bad MIDI data
742 * linuxsampler application:
743 - show available sampler engine types on startup
745 * general changes:
746 - support for muting sampler channels and solo mode of the same, two new
747 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
748 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
749 introduced for this, the behavior is the same like on a mixer console
750 (patch by Grigor Iliev, a bit adjusted). Also added configure option
751 --enable-process-muted-channels which can be used to enable the
752 processing of muted channels.
753 - support for sostenuto pedal
754 - support for monitoring the total number of active voices
757 - fixed some memory management errors
758 - fixed some concurrency problems that could lead to crashes when
759 LSCP commands were executed
760 - fixed crash when instrument loading failed previously on the same
761 sampler channel (fixes bug #36)
763 Version 0.3.3 (15 July 2005)
765 * packaging changes:
766 - fixed compilation with gcc 4.0
768 * Gigasampler format engine:
769 - LFO preprocessing was performed even though the respective LFO was
770 disabled by the instrument patch (minor efficiency fix)
771 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
772 for volume ramp downs in the same fragment (needed for current voice
773 stealing implementation) then simply inform the user with a warning
774 about possible click sounds and reduce the volume ramp down
775 appropriately instead of cancelling the audio device connection
777 Version 0.3.2 (24 June 2005)
779 * packaging changes:
780 - updated autotools build files to compile on OS X
781 (conditional compilation of CoreMIDI and MidiShare drivers)
782 - hand-crafted assembly optimization code can be disabled with
783 './configure --disable-asm' (definitely not recommended)
784 - fixed 'make dist' rule to include all necessary files
785 - require automake (>= 1.5) for 'make -f Makefile.cvs'
786 (due to 'dist-bzip2' automake option)
788 * Gigasampler format engine:
789 - support for the gig parameters for "release velocity response" curves
790 - fine tuning of the EGADSR envelope
791 - volume of release triggered samples now depends on note-on velocity,
792 note length and gig parameter "release trigger decay" instead of
793 note-off velocity.
794 - revised voice stealing
795 (fixes crash and endless loop caused by voice stealing)
796 - don't reset scale tuning on instrument or audio output device change
797 - handle key group conflicts right at the beginning of each fragment
798 instead of when the respective voice is actually launched
799 (fixes undefined behavior if stolen voices belonged to a key group -
800 this case was followed by a "killed voice survived" error message)
801 - fixed minor issue with null/silence samples
802 (those stole voices even though they don't need a voice at all which
803 resulted in "voice stealing didn't work out" messages)
804 - don't reset volume, pan, pitch and MIDI controller values on
805 instrument or audio output device change
807 * LSCP server:
808 - fixed some crashes (patch by Grigor Iliev, fixes #19)
809 - fixed LSCP event "CHANNEL_INFO" notification
810 (e.g. did not notify on volume changes or MIDI program change events)
812 * linuxsampler application:
813 - added command line parameters --lscp-addr and --lscp-port to override
814 default IP address and port of LSCP server
816 Version 0.3.1 (24 May 2005)
818 * initial release
