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

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

147 specified
149 * MIDI driver:
150 - ALSA MIDI driver supports now "NAME" device parameter, for overriding
151 the ALSA sequencer client name
152 - removed limit of maximum amount of MIDI ports per MIDI device, since
153 there is no reason for this limit
155 * audio driver:

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