3 * plugin changes:
4 - LV2 Persist + Files support (patch by David Robillard)
6 * packaging changes:
7 - fixed building with newer MinGW-w64

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
13 - fixed compilation with gcc 4.6.1

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

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

240 * Bug fixes:
241 - Fixed crash which may occur when MIDI key + transpose is out of range
242 - minor valgrind fixes
243 - fixed crash which occurred when changing an already deployed sampler
244 channel to a different engine type
245 - fixed crash when deleting a sampler channel or changing engine
246 type while an instrument load was in progress
247 - bugfix: playing a note while changing the instrument could cause
248 a crash, or give "Handing back unknown region" error messages
249 - bugfix: calling SET VOICES (which Fantasia does on start and
250 refresh) could cause instruments to be unloaded
251 - Mac OS X: fixed name collision of enum in EffectControl and
252 wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
253 - Mac OS X: fixed hanging threads
254 - Windows: disabled the previous thread fix on non-Mac systems, as
255 it caused hanging threads on Windows

257 after MIDI/audio device creation failure
259 Version 1.0.0 (31 July 2009)
261 * packaging changes:
262 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
263 causing e.g. the libgig test to fail when
264 "./configure --disable-jack-driver" was used
265 (patch by Alexis Ballier)
266 - fixed compilation with gcc 4.3
267 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
268 - fixed configure so it detects x86_64 (#107)
269 - fixes for building with newer MinGW versions
270 - fix for building with bison 2.4 (#111)
271 - fixed building with libgig installed in a non-standard directory
272 - minor fix in configure for mmsystem.h detection on MinGW
273 - Windows: look for editor plugins and Fantasia using base
274 directory of liblinuxsampler dll (look in the same directory and one
275 directory above)
276 - configure script fix: removed unconditional use of SSE
277 - fixed building with sqlite installed in a non-standard directory
278 - when cross-compiling, don't try to create instruments.db
279 - fix for new mingw-w64 version, which has usleep
281 * general changes:
282 - bugfix: on some POSIX systems instrument editor plugins refused to
283 load as we used a non-portable Linux specific struct field
284 (fixes bug #70, patch by Ronald Baljeu)
285 - fixed endless loop which occured when loading an instrument editor
286 plugin DLL on Windows systems failed
287 - fixed memory leaks that occurred when liblinuxsampler was unloaded
288 - optimized the SynchronizedConfig class so it doesn't wait
289 unnecessarily long after an update
290 - added support for notifying instrument editors on note-on / note-off
291 events (e.g. to highlight the pressed keys on the virtual keyboard
292 of gigedit)
293 - added support for triggering notes by instrument editors (see above)
294 - be verbose on DLL load errors (on Linux)
295 - fixed di-harmonic triangle LFO implementation (this LFO implementation
296 is only used by very few systems, most pick the int math
297 implementation, which is usually faster)
298 - fixes for audio drivers with varying buffer sizes
299 - experimental support for running LinuxSampler as a DSSI, LV2 and
300 VST plugin
301 - notification events for stream/voice count statistics are now sent
302 only when there are actual changes

304 multi-core and multi-cpu systems
305 - maximum voices and disk streams can now be altered at runtime
306 - fixed CPU feature detection on x86_64 (maybe fixes #108)
307 - automatic stacktrace mechanism is now turned off by default and can
308 be switched on by command line option "--stacktrace" (the automatic
309 stacktrace mechanism seems to be broken on most systems at the moment)
310 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
311 a pointer to the launched InstrumentEditor object
312 - added optional 3rd party user data parameter for following
313 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
314 InstrumentEditor::Launch(),
315 InstrumentManager::LaunchInstrumentEditor()
316 - theoretical fix: made SynchronizedConfig follow C++0x memory
317 model more strictly
318 - fixes for using large audio device buffers
319 - Windows: add the installation directory to the DLL search path
320 when loading an editor plugin (solves problems with VST and
321 gigedit on systems with other GTK versions installed)
323 * audio driver:
324 - removed the nonsense audio channel constraint (which was hard coded to
325 max. 100 audio channels) for most audio drivers
326 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
327 opposed to the LSCP specs
328 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
329 reflected the wrong value
330 - fixed a memory management bug in ASIO driver
331 - Makefile fix: JACK_CFLAGS wasn't used
332 - JACK: use jack_client_open instead of the deprecated
333 jack_client_new
334 - added (experimental) CoreAudio driver
335 - applied old fixes to the ASIO driver that were included in the
336 previous binary release but accidentally never committed to CVS
337 (fixes #117)
338 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
339 win64)
340 - VST: added support for sample rate and buffer size changes
341 - VST: close editor (Fantasia) when the VST is removed
342 - VST: avoid opening Fantasia more than once for each VST instance
343 - VST: export main function as "main" on Linux too (fix for
344 energyXT)
345 - VST: changed number of output channels from one stereo to 16
346 stereo
347 - added channel routing, fxsends and midi maps to the settings
348 stored in the plugin state
349 - performance optimization of AudioChannel::MixTo() and
350 AudioChannel::CopyTo() methods using GCC vector exensions
351 (if available)
352 - ASIO fixes: avoid initializing the device twice, avoid throwing
353 exception when getting parameters from a disconnected device
355 * MIDI driver:
356 - added JACK MIDI driver
357 - dispatch bank select as ordinary CC as well, the user might seriously
358 want to (mis)use it for some purpose ("fixed" in all current MIDI
359 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
360 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
361 CoreMidi or AU
362 - fixed mingw-w64 compilation error in MME driver
363 - made program change handling in MIDI thread real-time safe by
364 moving the logic to a non-RT thread
365 - fixed minor memory leak in ALSA driver
367 * instruments database:
368 - avoid time consuming samples scanning when adding instruments
369 to the instruments database
370 - added support for handling lost files in the instruments database
371 - Implemented option for adding instruments in separate directories
372 in the instruments database
373 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
374 - work-around for missing fnmatch function on Windows to make
375 instrument database compilable
376 - added instrument database support on Windows
377 works with both standalone mode and VST plugin.
378 the instruments DB file is located in
379 %USERPROFILE%\.linuxsampler\instruments.db which allows different
380 databases for each windows user
381 if no DB is present it automatically creates the .linuxsampler subdir
382 and then creates an empty DB
383 - fixed recursive import, which was broken on Windows
385 * Gigasampler format engine:
386 - fixed a memory leak that could happen when a channel was deleted
387 while notes were playing
388 - made it possible to load an instrument even if the audio thread
389 isn't running
390 - added partial support for the "Controller Triggered" MIDI rule,
391 enough for piano gigs with pedal noise samples
392 - minor fix: only mark FX sends as being modified if really the
393 respective FX send MIDI controller was used
394 - added support for GM global device volume SysEx message
395 (can be selected at compile time to either apply globally to the
396 whole sampler [default] or only to the sampler channels that are
397 connected to the respective MIDI input port the SysEx message arrived
398 on)
399 - bugfix: notes triggered at position 0 in the audio buffer were
400 sometimes wrongly killed in the same buffer, causing no sound to
401 be played
402 - added support for chromatic / drumkit mode Roland GS Sysex message
403 which is usally used to switch a part between chromatic sounds and
404 drumkit sounds (as opposed to their common default setting of MIDI
405 part 10 being a drumkit part and all other ones chromatic parts), in
406 LS however one can switch between the first 16 MIDI instrument maps
407 defined for the sampler
408 - made it possible to create multiple sample channels even if the
409 audio thread isn't running
410 - fixed crash when removing channel with active voices (#116)
411 - bugfix: on sample reference changes (instrument editor), only
412 un-cache the respective sample if it's really not used by any
413 sampler engine anymore
414 - re-cache samples in case they were changed by an instrument editor,
415 e.g. when a sample was added while playing (#82)
416 - fixed hanging notes which occured when note-off event had the exact
417 same time stamp as the voice's note-on event and occured both in the
418 same audio fragment cycle (fixes bug #112)
419 - added support for the "fine tune" and "pitch bend range"
420 instrument-level gig parameters
421 - fixed minor artifacts in pitch bend handling
422 - added support for GS Reset SysEx message
423 - allow gig files to use unlimited downward pitch shifting
424 - added a limit check for upward pitch shifting
425 - bugfix: sometimes, when playing a note twice fast, the second
426 note was silent
427 - fixed crash happening when a pitch bend event arrived at the
428 same time a new instrument was loading
430 * LSCP server:
431 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
432 react on MIDI data arriving on certain sampler channels (so far only
433 Note-On and Note-Off events are sent via this LSCP event)
434 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
435 react on MIDI data arriving on certain MIDI input devices (so far only
436 Note-On and Note-Off events are sent via this LSCP event)
437 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
439 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
440 frontends to send MIDI messages to specific sampler channel
441 - added two additional fields to GET FILE INSTRUMENT INFO command -
443 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
444 was incorrect
445 - Optimized the retrieval of the MIDI instrument mappings
446 - added new LSCP command "SET VOICES" to globally alter the maximum
447 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
448 be triggered respectively
449 - added new LSCP command "SET STREAMS" to globally alter the maximum
450 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
451 which will be triggered respectively
452 - bugfix: retry if "select" returns EINTR (this fixes a crash when
453 a gigedit file dialog is opened)
454 - close all connections when LSCPServer is deleted
455 - hard close of all sockets on exit
456 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
457 driver
459 * Bug fixes:
460 - fixed a crash which occurs when removing a sampler channel waiting
461 to start instrument loading after another channel
462 - fixed a crash which occurs when removing a sampler channel with
463 instrument loading in progress (bug #113)
464 - fixed termination caused by uncaught exception when adding MIDI
465 instrument with PERSISTENT load mode
466 - fixed possible iterator invalidations when resetting the sampler
467 - fixed memory leaks when issuing the following LSCP commands:
472 - fixed possible compilation error when sqlite is not present
473 - fixed orphaned pointers when setting maximum voices limit (bug #118)
474 - fixed crash when changing the audio output device of a sampler
475 channel with loaded instrument and start playing notes
476 - fixed endless loop in Engine::SuspendAll() (bug #120)
477 - fixed a low-level atomic load function that was broken on 64-bit
478 PowerPC, which probably could cause crashes on that platform
479 - fixed a memory management error which could cause a crash when a
480 plugin was unloaded
481 - bugfix: two private structs had the same name, which could cause
482 problems if the linker chose the wrong constructor
483 - fixed low-level ConditionServer usage bug that caused lockups on
484 Windows
487 Version 0.5.1 (6 December 2007)
489 * packaging changes:
490 - added autoconf checks for pthread library
491 - added autoconf check for pthread bug found on certain NPTL-enabled
492 glibc versions (see Gentoo bug report #194076)
493 - added autoconf checks for MS Windows
495 * general changes:
496 - bugfix: the thread used by an editor plugin didn't die when the
497 editor closed
498 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
499 out all the space. operator--() did not apply size_mask after
500 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
501 order to avoid problems with the _NonVolatileReader functions.
502 - bugfix: Stream.h: added a missing divide by BytesPerSample in
503 GetWriteSpace(). Since this function is currently only used in
504 the stream's qsort() compare function, it didn't trigger any
505 bugs.
506 - Resampler.h, Synthesizer.h: cubic interpolation now works in
507 24bit mode too. Faster method to read 24bit words on little
508 endian machines (x86): replaced 3 byte reads + shifts with a 1
509 unaligned 32bit read and shift
510 - experimental support for MS Windows (MIDI input via MME, AUDIO
511 output via ASIO)
512 - made handling of SIGINT signal (Ctrl-C) a bit more robust
513 - support for monitoring the total number of active disk streams
514 (new LSCP commands: GET TOTAL_STREAM_COUNT,
517 * AUDIO driver:
518 - added Windows ASIO low latency audio driver
520 * MIDI driver:
521 - added MME Windows MIDI driver
523 * LSCP server:
524 - added support for Windows style path / filenames, however with
525 forward slash path separators instead of backslash
526 (i.e. "C:/foo/bar.gig")
527 - allow naughty liblscp to send non-string device parameters within
528 apostrophes as well
529 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
530 "LIST FILE INSTRUMENTS <file>" and
531 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
532 about an arbitrary instrument file on the system where the sampler is
533 running on
535 Version 0.5.0 (15 October 2007)
537 * packaging changes:
538 - config.h is not going to be installed along with liblinuxsampler's
539 API header files anymore
540 - only the API relevant header (and source) files will be exported to
541 the Doxygen API documentation (explicitly listed in Doxyfile.in)
542 - added completely new XCode project files for Mac OSX which is now
543 capable to execute our autoconf environment, thus no need anymore
544 to maintain the compile time configuration file (osx/version.h) for
545 OSX manually (patch by Toshi Nagata)
546 - fixed buggy boolean --enable-foo / --disable-foo configure script
547 parameters
548 - global.h now only covers global definitions that are needed for the
549 C++ API header files, all implementation internal global definitions
550 are now in global_private.h
551 - atomic.h is not exposed to the C++ API anymore
552 - no need to include config.h anymore for using LS's API header files
553 - fixed warnings in API doc generation
555 * general changes:
556 - replaced the old, confusing MIDI program change mechanism by a
557 flexible MIDI instrument mapper which allows to map arbitrary
558 (MIDI bank, MIDI program) pairs with arbitrary
559 (engine type, instrument file, file index) triplets which will be
560 loaded on the respective channel when such MIDI program change
561 messages arrive, beside that, each entry allows to define a life-time
562 strategy for the instrument, so the user can define whether the
563 instrument should i.e. be permanently loaded (to be able to switch
564 quickly among sounds) or i.e. loaded just on demand when the
565 respective program change arrives (to safe RAM space), as well as a
566 global volume factor for each entry, so the user can adjust the volume
567 dynamic of his mapped instrument collection without having to modify
568 the instrument files, also one can manage arbitrary amount of such
569 MIDI instrument maps and assign each sampler channel individually
570 a certain map, so that i.e. separation of normal instruments and
571 drumkits is possible
572 - new notification events for tracking changes to audio/MIDI devices,
573 MIDI instrument maps, MIDI instruments, FX sends, global volume.
574 - sampler was limited to load max. 200 instruments in the background
575 due to a constant size RingBuffer FIFO which is now replaced by a
576 dynamic (unlimited) size std::list FIFO
577 - added FX sends, these allow to route audio signals to arbitrary audio
578 output channels for being processed by external effect processors
579 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
580 controllers
581 - global (sampler wide) volume can now be controlled at runtime
582 - Implemented new, improved notification system
583 - fixed compilation errors regarding OSX
584 (patch by Toshi Nagata)
585 - implemented instruments database
586 - added support for escape sequences to the instruments database
587 - added highly experimental support for on-the-fly instrument editing
588 within the sampler's process (by using instrument editor plugins),
589 you'll notice the new "Registered instrument editors:" message on
590 startup, added a new LSCP command:
591 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
592 to spawn a matching instrument editor for the instrument on the
593 given sampler channel, the plugin path can be overridden at compile
594 time with ./configure --enable-plugin-dir=/some/dir
595 - added experimental code for synchronizing instrument editors hosted
596 in the sampler's process to safely edit instruments while playing
597 without a crash (hopefully) by either suspending single regions
598 wherever possible or if unavoidable whole engine(s)
599 - fixed several issues in fundamental "Thread" class: set scheduling
600 policy and priority on thread level, set a minimum stack size for
601 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
602 threads simply inherited properties of starting thread instead of
603 setting their own policy and priority
604 - minor fix in our automatic stack trace mechanism on crashes, the
605 main process did not wait for the stack trace process to finish
606 its output
607 - fixed some minor memory leaks
608 - reenabled assembly features support, at the moment only for
609 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
610 - minor assembly fix in x86 features detection (don't use the PIC
611 register, to avoid relocations in the text segment at runtime)
612 - POSIX callback functions of Thread.h are hidden
614 * MIDI driver:
615 - dispatch bank select (MSB and LSB) messages
617 * audio driver:
618 - the ALSA audio output driver parameters now reflect the correct
619 parameter value ranges for the respective selected sound card
620 (patch by Till Wimmer, a bit fixed and extended)
622 * Gigasampler format engine:
623 - if a filter is used and EG2 finishes before EG1, let the voice
624 die when EG2 has finished (this fixes a problem with clicks and
625 voice starvation for some gigs)
626 - playback is no longer disabled during instrument loading
627 - all notes playing on a channel that changes its instrument keep
628 playing with the old instrument until they get a note off
629 command
630 - EG fix: a release value of zero could cause noises or crash
631 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
632 - EG fine tuning: when attack is zero the EG starts at a level
633 above max sustain level, which means that there is a decay phase
634 even if sustain is 100%
635 - more EG fixes: the level could sometimes go below zero and cause
636 noises or crashes
637 - minor fix of EGDecay (patch by Toshi Nagata)
638 - fixed compiler error when --enable-override-filter-type was
639 supplied to the configure script (fixes #46)
640 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
641 instead of a fix value
642 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
643 127 (solo mode) only kill voices if the respective mode really
644 changed
646 * LSCP server:
647 - fixed compile time error for old Bison versions
648 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
649 - parser now supports extended ASCII character set
650 (up to ASCII code 255, i.e. includes now umlauts and accents)
651 - filename arguments in LSCP commands now allow to use escape
652 sequences, that is directly literal as one of: \', \", \\, \n, \r,
653 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
654 code value like \xf2) (fixes bug #24)
655 - the following LSCP commands now also support escape sequences for at
656 least one of their text-based parameters (i.e. name, description):
663 - returns verbose syntax errors (line and column where syntax error
664 occured, the unexpected character and the actually expected, possible
665 character(s), the latter only if less than 5 possibilities)
666 - made sure that LSCP syntax is not affected by gigedit locale
667 settings
668 - bugfix regarding strings parameter lists: all comma separated lists
669 of strings were treated as being one string containing commas
670 (fixes #57)
672 * Bug fixes:
673 - fixed crash occurring on certain LSCP scripts (Bug 39)
674 - another thread safety fix for lscp "load engine" and "set
675 channel audio output device"
676 - fixed a crash which occurs when reassigning the same engine
677 on a sampler channel with connected MIDI device
678 - fixed a crash which occurs when changing the number of ports of a MIDI
679 device connected to a sampler channel to number less then or equal
680 to the index of the port to which the sampler channel is connected.
681 - The previous bindings were not been disconnected when altering
682 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
683 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
684 - The active stream/voice count statistic was incorrect.
685 - notification events were not been sent for some sampler
686 channel changes
687 - added default min and max values to restrict the number of allowed
688 audio output channels and MIDI input ports
689 - the connection to the PCM interface is now closed when destroying
690 an audio output device
691 - files with slash in their path or filename could not be loaded
693 * test cases:
694 - updated and fixed (haven't been touched in a while)
696 Version 0.4.0 (24 November 2006)
698 * packaging changes:
699 - changed deprecated copyright attribute to license; added ldconfig
700 to post-(un)install steps; added devel package for liblinuxsampler;
701 to linuxsampler.spec (RPM)
702 - install necessary development header files for allowing 3rd party
703 applications to link against liblinuxsampler
704 - liblinuxsampler's API documentation can be generated with 'make docs'
705 (Doxygen required)
706 - added benchmark to automatically detect the best triangle LFO
707 implementation (currently either an integer math solution or a
708 di-harmonic approximation), automatic detection can be overriden
709 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
710 configure script argument though (mandatory for cross-compilation)
711 - do not automatically pick optimized gcc flags if the user already
712 provided some on his own (as CXXFLAGS)
713 - added compile time option to disable processing of All-Notes-Off MIDI
714 messages
715 - added compile time options to allow disabling the various audio and
716 MIDI drivers
717 - fixed automatic GCC CPU switch detection on PPC
718 (patch by Ebrahim Mayat)
720 * Gigasampler format engine:
721 - extensive synthesis optimization
722 (reimplementation of EGs and LFO(s), removed synthesis parameter
723 prerendering and the synthesis parameter matrix in general, splitting
724 each audio fragment into subfragments now where each subfragment uses
725 constant pitch and filter coefficients. The volume coefficient is
726 linearly interpolated inside a subfragment, unless
727 --disable-interpolate-volume is set.)
728 - fine tuning of the EG modulation parameters
729 - improved filter cutoff calculation by adding support for the
730 following gig parameters: Cutoff freq (used when no cutoff
731 controller is defined), Control invert, Minimum cutoff, Velocity
732 curve and Velocity range. The keyboard tracking now scales
733 cutoff frequency instead of resonance.
734 - added support for gig parameter Resonance.
735 - fixed bug in sysex handling (patch by Juan Linietsky)
736 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
737 which can be overridden with --enable-global-attenuation
738 - EG fixes: made the length of "attack hold" stage more
739 accurate. Release stage can now start before attack stage
740 ends. Cancel release didn't work when sustain was zero. Attack
741 time now has a minimal value to prevent clicks.
742 - fixed pitch changes larger than one octave
743 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
744 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
745 all modes can be altered via standard GM messages, that is CC5 for
746 altering portamento time, CC65 for enabling / disabling portamento
747 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
748 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
749 parameter) and crossfade
750 - added support for the "attenuation controller threshold" gig
751 parameter
752 - added smoothing of volume changes caused by control change
753 messages
754 - sample loop parameters are now taken from the DimensionRegion
755 instead of the wave chunk
756 - fixed keyswitching for v3 gigs with a number of keyswitch splits
757 not equal to a power of two
758 - reimplementation of the filter algorithm. The new filter is more
759 accurate and supports all gig filter types, including bandreject
760 and lowpass turbo.
761 - real support for 24 bit samples - samples are not truncated to
762 16 bits anymore
763 - support for aftertouch (channel pressure, not polyphonic
764 aftertouch)
765 - LFO1 behaviour fixed (dampening from max volume instead of
766 amplifying from 0)
768 * LSCP server:
769 - fixed application exit on broken pipe error (fixes bug #20)
770 - fixed the notification messages delay due to lack of
771 network activity (fixes bug #26)
772 - fixed parser bug which occured on space(s) within device parameters
775 * audio driver:
776 - added aRts audio output driver (by no means RT safe)
778 * MIDI driver:
779 - fixed legacy sysex code which caused dispatching of MIDI SysEx
780 messages several times instead of once
781 - API extension for MIDI drivers which already supply exact time stamps
782 for events (i.e. for offline rendering based MIDI drivers)
783 - added checks for bad MIDI data
785 * linuxsampler application:
786 - show available sampler engine types on startup
788 * general changes:
789 - support for muting sampler channels and solo mode of the same, two new
790 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
791 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
792 introduced for this, the behavior is the same like on a mixer console
793 (patch by Grigor Iliev, a bit adjusted). Also added configure option
794 --enable-process-muted-channels which can be used to enable the
795 processing of muted channels.
796 - support for sostenuto pedal
797 - support for monitoring the total number of active voices
800 - fixed some memory management errors
801 - fixed some concurrency problems that could lead to crashes when
802 LSCP commands were executed
803 - fixed crash when instrument loading failed previously on the same
804 sampler channel (fixes bug #36)
806 Version 0.3.3 (15 July 2005)
808 * packaging changes:
809 - fixed compilation with gcc 4.0
811 * Gigasampler format engine:
812 - LFO preprocessing was performed even though the respective LFO was
813 disabled by the instrument patch (minor efficiency fix)
814 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
815 for volume ramp downs in the same fragment (needed for current voice
816 stealing implementation) then simply inform the user with a warning
817 about possible click sounds and reduce the volume ramp down
818 appropriately instead of cancelling the audio device connection
820 Version 0.3.2 (24 June 2005)
822 * packaging changes:
823 - updated autotools build files to compile on OS X
824 (conditional compilation of CoreMIDI and MidiShare drivers)
825 - hand-crafted assembly optimization code can be disabled with
826 './configure --disable-asm' (definitely not recommended)
827 - fixed 'make dist' rule to include all necessary files
828 - require automake (>= 1.5) for 'make -f Makefile.cvs'
829 (due to 'dist-bzip2' automake option)
831 * Gigasampler format engine:
832 - support for the gig parameters for "release velocity response" curves
833 - fine tuning of the EGADSR envelope
834 - volume of release triggered samples now depends on note-on velocity,
835 note length and gig parameter "release trigger decay" instead of
836 note-off velocity.
837 - revised voice stealing
838 (fixes crash and endless loop caused by voice stealing)
839 - don't reset scale tuning on instrument or audio output device change
840 - handle key group conflicts right at the beginning of each fragment
841 instead of when the respective voice is actually launched
842 (fixes undefined behavior if stolen voices belonged to a key group -
843 this case was followed by a "killed voice survived" error message)
844 - fixed minor issue with null/silence samples
845 (those stole voices even though they don't need a voice at all which
846 resulted in "voice stealing didn't work out" messages)
847 - don't reset volume, pan, pitch and MIDI controller values on
848 instrument or audio output device change
850 * LSCP server:
851 - fixed some crashes (patch by Grigor Iliev, fixes #19)
852 - fixed LSCP event "CHANNEL_INFO" notification
853 (e.g. did not notify on volume changes or MIDI program change events)
855 * linuxsampler application:
856 - added command line parameters --lscp-addr and --lscp-port to override
857 default IP address and port of LSCP server
859 Version 0.3.1 (24 May 2005)
861 * initial release
