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

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

266 after MIDI/audio device creation failure
268 Version 1.0.0 (31 July 2009)
270 * packaging changes:
271 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
272 causing e.g. the libgig test to fail when
273 "./configure --disable-jack-driver" was used
274 (patch by Alexis Ballier)
275 - fixed compilation with gcc 4.3
276 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
277 - fixed configure so it detects x86_64 (#107)
278 - fixes for building with newer MinGW versions

280 - fixed building with libgig installed in a non-standard directory
281 - minor fix in configure for mmsystem.h detection on MinGW
282 - Windows: look for editor plugins and Fantasia using base
283 directory of liblinuxsampler dll (look in the same directory and one
284 directory above)
285 - configure script fix: removed unconditional use of SSE
286 - fixed building with sqlite installed in a non-standard directory
287 - when cross-compiling, don't try to create instruments.db
288 - fix for new mingw-w64 version, which has usleep
290 * general changes:
291 - bugfix: on some POSIX systems instrument editor plugins refused to
292 load as we used a non-portable Linux specific struct field
293 (fixes bug #70, patch by Ronald Baljeu)
294 - fixed endless loop which occured when loading an instrument editor
295 plugin DLL on Windows systems failed
296 - fixed memory leaks that occurred when liblinuxsampler was unloaded
297 - optimized the SynchronizedConfig class so it doesn't wait
298 unnecessarily long after an update
299 - added support for notifying instrument editors on note-on / note-off
300 events (e.g. to highlight the pressed keys on the virtual keyboard
301 of gigedit)
302 - added support for triggering notes by instrument editors (see above)
303 - be verbose on DLL load errors (on Linux)
304 - fixed di-harmonic triangle LFO implementation (this LFO implementation
305 is only used by very few systems, most pick the int math
306 implementation, which is usually faster)
307 - fixes for audio drivers with varying buffer sizes
308 - experimental support for running LinuxSampler as a DSSI, LV2 and
309 VST plugin
310 - notification events for stream/voice count statistics are now sent
311 only when there are actual changes

313 multi-core and multi-cpu systems
314 - maximum voices and disk streams can now be altered at runtime
315 - fixed CPU feature detection on x86_64 (maybe fixes #108)
316 - automatic stacktrace mechanism is now turned off by default and can
317 be switched on by command line option "--stacktrace" (the automatic
318 stacktrace mechanism seems to be broken on most systems at the moment)
319 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
320 a pointer to the launched InstrumentEditor object
321 - added optional 3rd party user data parameter for following
322 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
323 InstrumentEditor::Launch(),
324 InstrumentManager::LaunchInstrumentEditor()
325 - theoretical fix: made SynchronizedConfig follow C++0x memory
326 model more strictly
327 - fixes for using large audio device buffers
328 - Windows: add the installation directory to the DLL search path
329 when loading an editor plugin (solves problems with VST and
330 gigedit on systems with other GTK versions installed)
332 * audio driver:
333 - removed the nonsense audio channel constraint (which was hard coded to
334 max. 100 audio channels) for most audio drivers
335 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
336 opposed to the LSCP specs
337 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
338 reflected the wrong value
339 - fixed a memory management bug in ASIO driver
340 - Makefile fix: JACK_CFLAGS wasn't used
341 - JACK: use jack_client_open instead of the deprecated
342 jack_client_new
343 - added (experimental) CoreAudio driver
344 - applied old fixes to the ASIO driver that were included in the
345 previous binary release but accidentally never committed to CVS
346 (fixes #117)
347 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
348 win64)
349 - VST: added support for sample rate and buffer size changes
350 - VST: close editor (Fantasia) when the VST is removed
351 - VST: avoid opening Fantasia more than once for each VST instance
352 - VST: export main function as "main" on Linux too (fix for
353 energyXT)
354 - VST: changed number of output channels from one stereo to 16
355 stereo
356 - added channel routing, fxsends and midi maps to the settings
357 stored in the plugin state
358 - performance optimization of AudioChannel::MixTo() and
359 AudioChannel::CopyTo() methods using GCC vector exensions
360 (if available)
361 - ASIO fixes: avoid initializing the device twice, avoid throwing
362 exception when getting parameters from a disconnected device
364 * MIDI driver:
365 - added JACK MIDI driver
366 - dispatch bank select as ordinary CC as well, the user might seriously
367 want to (mis)use it for some purpose ("fixed" in all current MIDI
368 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
369 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
370 CoreMidi or AU
371 - fixed mingw-w64 compilation error in MME driver
372 - made program change handling in MIDI thread real-time safe by
373 moving the logic to a non-RT thread
374 - fixed minor memory leak in ALSA driver
376 * instruments database:
377 - avoid time consuming samples scanning when adding instruments
378 to the instruments database
379 - added support for handling lost files in the instruments database
380 - Implemented option for adding instruments in separate directories
381 in the instruments database
382 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
383 - work-around for missing fnmatch function on Windows to make
384 instrument database compilable
385 - added instrument database support on Windows
386 works with both standalone mode and VST plugin.
387 the instruments DB file is located in
388 %USERPROFILE%\.linuxsampler\instruments.db which allows different
389 databases for each windows user
390 if no DB is present it automatically creates the .linuxsampler subdir
391 and then creates an empty DB
392 - fixed recursive import, which was broken on Windows
394 * Gigasampler format engine:
395 - fixed a memory leak that could happen when a channel was deleted
396 while notes were playing
397 - made it possible to load an instrument even if the audio thread
398 isn't running
399 - added partial support for the "Controller Triggered" MIDI rule,
400 enough for piano gigs with pedal noise samples
401 - minor fix: only mark FX sends as being modified if really the
402 respective FX send MIDI controller was used
403 - added support for GM global device volume SysEx message
404 (can be selected at compile time to either apply globally to the
405 whole sampler [default] or only to the sampler channels that are
406 connected to the respective MIDI input port the SysEx message arrived
407 on)
408 - bugfix: notes triggered at position 0 in the audio buffer were
409 sometimes wrongly killed in the same buffer, causing no sound to
410 be played
411 - added support for chromatic / drumkit mode Roland GS Sysex message
412 which is usally used to switch a part between chromatic sounds and
413 drumkit sounds (as opposed to their common default setting of MIDI
414 part 10 being a drumkit part and all other ones chromatic parts), in
415 LS however one can switch between the first 16 MIDI instrument maps
416 defined for the sampler
417 - made it possible to create multiple sample channels even if the
418 audio thread isn't running
419 - fixed crash when removing channel with active voices (#116)
420 - bugfix: on sample reference changes (instrument editor), only
421 un-cache the respective sample if it's really not used by any
422 sampler engine anymore
423 - re-cache samples in case they were changed by an instrument editor,
424 e.g. when a sample was added while playing (#82)
425 - fixed hanging notes which occured when note-off event had the exact
426 same time stamp as the voice's note-on event and occured both in the
427 same audio fragment cycle (fixes bug #112)
428 - added support for the "fine tune" and "pitch bend range"
429 instrument-level gig parameters
430 - fixed minor artifacts in pitch bend handling
431 - added support for GS Reset SysEx message
432 - allow gig files to use unlimited downward pitch shifting
433 - added a limit check for upward pitch shifting
434 - bugfix: sometimes, when playing a note twice fast, the second
435 note was silent
436 - fixed crash happening when a pitch bend event arrived at the
437 same time a new instrument was loading
439 * LSCP server:
440 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
441 react on MIDI data arriving on certain sampler channels (so far only
442 Note-On and Note-Off events are sent via this LSCP event)
443 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
444 react on MIDI data arriving on certain MIDI input devices (so far only
445 Note-On and Note-Off events are sent via this LSCP event)
446 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
448 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
449 frontends to send MIDI messages to specific sampler channel
450 - added two additional fields to GET FILE INSTRUMENT INFO command -
452 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
453 was incorrect
454 - Optimized the retrieval of the MIDI instrument mappings
455 - added new LSCP command "SET VOICES" to globally alter the maximum
456 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
457 be triggered respectively
458 - added new LSCP command "SET STREAMS" to globally alter the maximum
459 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
460 which will be triggered respectively
461 - bugfix: retry if "select" returns EINTR (this fixes a crash when
462 a gigedit file dialog is opened)
463 - close all connections when LSCPServer is deleted
464 - hard close of all sockets on exit
465 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
466 driver
468 * Bug fixes:
469 - fixed a crash which occurs when removing a sampler channel waiting
470 to start instrument loading after another channel
471 - fixed a crash which occurs when removing a sampler channel with
472 instrument loading in progress (bug #113)
473 - fixed termination caused by uncaught exception when adding MIDI
474 instrument with PERSISTENT load mode
475 - fixed possible iterator invalidations when resetting the sampler
476 - fixed memory leaks when issuing the following LSCP commands:
481 - fixed possible compilation error when sqlite is not present
482 - fixed orphaned pointers when setting maximum voices limit (bug #118)
483 - fixed crash when changing the audio output device of a sampler
484 channel with loaded instrument and start playing notes
485 - fixed endless loop in Engine::SuspendAll() (bug #120)
486 - fixed a low-level atomic load function that was broken on 64-bit
487 PowerPC, which probably could cause crashes on that platform
488 - fixed a memory management error which could cause a crash when a
489 plugin was unloaded
490 - bugfix: two private structs had the same name, which could cause
491 problems if the linker chose the wrong constructor
492 - fixed low-level ConditionServer usage bug that caused lockups on
493 Windows
496 Version 0.5.1 (6 December 2007)
498 * packaging changes:
499 - added autoconf checks for pthread library
500 - added autoconf check for pthread bug found on certain NPTL-enabled
501 glibc versions (see Gentoo bug report #194076)
502 - added autoconf checks for MS Windows
504 * general changes:
505 - bugfix: the thread used by an editor plugin didn't die when the
506 editor closed
507 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
508 out all the space. operator--() did not apply size_mask after
509 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
510 order to avoid problems with the _NonVolatileReader functions.
511 - bugfix: Stream.h: added a missing divide by BytesPerSample in
512 GetWriteSpace(). Since this function is currently only used in
513 the stream's qsort() compare function, it didn't trigger any
514 bugs.
515 - Resampler.h, Synthesizer.h: cubic interpolation now works in
516 24bit mode too. Faster method to read 24bit words on little
517 endian machines (x86): replaced 3 byte reads + shifts with a 1
518 unaligned 32bit read and shift
519 - experimental support for MS Windows (MIDI input via MME, AUDIO
520 output via ASIO)
521 - made handling of SIGINT signal (Ctrl-C) a bit more robust
522 - support for monitoring the total number of active disk streams
523 (new LSCP commands: GET TOTAL_STREAM_COUNT,
526 * AUDIO driver:
527 - added Windows ASIO low latency audio driver
529 * MIDI driver:
530 - added MME Windows MIDI driver
532 * LSCP server:
533 - added support for Windows style path / filenames, however with
534 forward slash path separators instead of backslash
535 (i.e. "C:/foo/bar.gig")
536 - allow naughty liblscp to send non-string device parameters within
537 apostrophes as well
538 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
539 "LIST FILE INSTRUMENTS <file>" and
540 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
541 about an arbitrary instrument file on the system where the sampler is
542 running on
544 Version 0.5.0 (15 October 2007)
546 * packaging changes:
547 - config.h is not going to be installed along with liblinuxsampler's
548 API header files anymore
549 - only the API relevant header (and source) files will be exported to
550 the Doxygen API documentation (explicitly listed in Doxyfile.in)
551 - added completely new XCode project files for Mac OSX which is now
552 capable to execute our autoconf environment, thus no need anymore
553 to maintain the compile time configuration file (osx/version.h) for
554 OSX manually (patch by Toshi Nagata)
555 - fixed buggy boolean --enable-foo / --disable-foo configure script
556 parameters
557 - global.h now only covers global definitions that are needed for the
558 C++ API header files, all implementation internal global definitions
559 are now in global_private.h
560 - atomic.h is not exposed to the C++ API anymore
561 - no need to include config.h anymore for using LS's API header files
562 - fixed warnings in API doc generation
564 * general changes:
565 - replaced the old, confusing MIDI program change mechanism by a
566 flexible MIDI instrument mapper which allows to map arbitrary
567 (MIDI bank, MIDI program) pairs with arbitrary
568 (engine type, instrument file, file index) triplets which will be
569 loaded on the respective channel when such MIDI program change
570 messages arrive, beside that, each entry allows to define a life-time
571 strategy for the instrument, so the user can define whether the
572 instrument should i.e. be permanently loaded (to be able to switch
573 quickly among sounds) or i.e. loaded just on demand when the
574 respective program change arrives (to safe RAM space), as well as a
575 global volume factor for each entry, so the user can adjust the volume
576 dynamic of his mapped instrument collection without having to modify
577 the instrument files, also one can manage arbitrary amount of such
578 MIDI instrument maps and assign each sampler channel individually
579 a certain map, so that i.e. separation of normal instruments and
580 drumkits is possible
581 - new notification events for tracking changes to audio/MIDI devices,
582 MIDI instrument maps, MIDI instruments, FX sends, global volume.
583 - sampler was limited to load max. 200 instruments in the background
584 due to a constant size RingBuffer FIFO which is now replaced by a
585 dynamic (unlimited) size std::list FIFO
586 - added FX sends, these allow to route audio signals to arbitrary audio
587 output channels for being processed by external effect processors
588 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
589 controllers
590 - global (sampler wide) volume can now be controlled at runtime
591 - Implemented new, improved notification system
592 - fixed compilation errors regarding OSX
593 (patch by Toshi Nagata)
594 - implemented instruments database
595 - added support for escape sequences to the instruments database
596 - added highly experimental support for on-the-fly instrument editing
597 within the sampler's process (by using instrument editor plugins),
598 you'll notice the new "Registered instrument editors:" message on
599 startup, added a new LSCP command:
600 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
601 to spawn a matching instrument editor for the instrument on the
602 given sampler channel, the plugin path can be overridden at compile
603 time with ./configure --enable-plugin-dir=/some/dir
604 - added experimental code for synchronizing instrument editors hosted
605 in the sampler's process to safely edit instruments while playing
606 without a crash (hopefully) by either suspending single regions
607 wherever possible or if unavoidable whole engine(s)
608 - fixed several issues in fundamental "Thread" class: set scheduling
609 policy and priority on thread level, set a minimum stack size for
610 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
611 threads simply inherited properties of starting thread instead of
612 setting their own policy and priority
613 - minor fix in our automatic stack trace mechanism on crashes, the
614 main process did not wait for the stack trace process to finish
615 its output
616 - fixed some minor memory leaks
617 - reenabled assembly features support, at the moment only for
618 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
619 - minor assembly fix in x86 features detection (don't use the PIC
620 register, to avoid relocations in the text segment at runtime)
621 - POSIX callback functions of Thread.h are hidden
623 * MIDI driver:
624 - dispatch bank select (MSB and LSB) messages
626 * audio driver:
627 - the ALSA audio output driver parameters now reflect the correct
628 parameter value ranges for the respective selected sound card
629 (patch by Till Wimmer, a bit fixed and extended)
631 * Gigasampler format engine:
632 - if a filter is used and EG2 finishes before EG1, let the voice
633 die when EG2 has finished (this fixes a problem with clicks and
634 voice starvation for some gigs)
635 - playback is no longer disabled during instrument loading
636 - all notes playing on a channel that changes its instrument keep
637 playing with the old instrument until they get a note off
638 command
639 - EG fix: a release value of zero could cause noises or crash
640 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
641 - EG fine tuning: when attack is zero the EG starts at a level
642 above max sustain level, which means that there is a decay phase
643 even if sustain is 100%
644 - more EG fixes: the level could sometimes go below zero and cause
645 noises or crashes
646 - minor fix of EGDecay (patch by Toshi Nagata)
647 - fixed compiler error when --enable-override-filter-type was
648 supplied to the configure script (fixes #46)
649 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
650 instead of a fix value
651 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
652 127 (solo mode) only kill voices if the respective mode really
653 changed
655 * LSCP server:
656 - fixed compile time error for old Bison versions
657 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
658 - parser now supports extended ASCII character set
659 (up to ASCII code 255, i.e. includes now umlauts and accents)
660 - filename arguments in LSCP commands now allow to use escape
661 sequences, that is directly literal as one of: \', \", \\, \n, \r,
662 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
663 code value like \xf2) (fixes bug #24)
664 - the following LSCP commands now also support escape sequences for at
665 least one of their text-based parameters (i.e. name, description):
672 - returns verbose syntax errors (line and column where syntax error
673 occured, the unexpected character and the actually expected, possible
674 character(s), the latter only if less than 5 possibilities)
675 - made sure that LSCP syntax is not affected by gigedit locale
676 settings
677 - bugfix regarding strings parameter lists: all comma separated lists
678 of strings were treated as being one string containing commas
679 (fixes #57)
681 * Bug fixes:
682 - fixed crash occurring on certain LSCP scripts (Bug 39)
683 - another thread safety fix for lscp "load engine" and "set
684 channel audio output device"
685 - fixed a crash which occurs when reassigning the same engine
686 on a sampler channel with connected MIDI device
687 - fixed a crash which occurs when changing the number of ports of a MIDI
688 device connected to a sampler channel to number less then or equal
689 to the index of the port to which the sampler channel is connected.
690 - The previous bindings were not been disconnected when altering
691 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
692 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
693 - The active stream/voice count statistic was incorrect.
694 - notification events were not been sent for some sampler
695 channel changes
696 - added default min and max values to restrict the number of allowed
697 audio output channels and MIDI input ports
698 - the connection to the PCM interface is now closed when destroying
699 an audio output device
700 - files with slash in their path or filename could not be loaded
702 * test cases:
703 - updated and fixed (haven't been touched in a while)
705 Version 0.4.0 (24 November 2006)
707 * packaging changes:
708 - changed deprecated copyright attribute to license; added ldconfig
709 to post-(un)install steps; added devel package for liblinuxsampler;
710 to linuxsampler.spec (RPM)
711 - install necessary development header files for allowing 3rd party
712 applications to link against liblinuxsampler
713 - liblinuxsampler's API documentation can be generated with 'make docs'
714 (Doxygen required)
715 - added benchmark to automatically detect the best triangle LFO
716 implementation (currently either an integer math solution or a
717 di-harmonic approximation), automatic detection can be overriden
718 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
719 configure script argument though (mandatory for cross-compilation)
720 - do not automatically pick optimized gcc flags if the user already
721 provided some on his own (as CXXFLAGS)
722 - added compile time option to disable processing of All-Notes-Off MIDI
723 messages
724 - added compile time options to allow disabling the various audio and
725 MIDI drivers
726 - fixed automatic GCC CPU switch detection on PPC
727 (patch by Ebrahim Mayat)
729 * Gigasampler format engine:
730 - extensive synthesis optimization
731 (reimplementation of EGs and LFO(s), removed synthesis parameter
732 prerendering and the synthesis parameter matrix in general, splitting
733 each audio fragment into subfragments now where each subfragment uses
734 constant pitch and filter coefficients. The volume coefficient is
735 linearly interpolated inside a subfragment, unless
736 --disable-interpolate-volume is set.)
737 - fine tuning of the EG modulation parameters
738 - improved filter cutoff calculation by adding support for the
739 following gig parameters: Cutoff freq (used when no cutoff
740 controller is defined), Control invert, Minimum cutoff, Velocity
741 curve and Velocity range. The keyboard tracking now scales
742 cutoff frequency instead of resonance.
743 - added support for gig parameter Resonance.
744 - fixed bug in sysex handling (patch by Juan Linietsky)
745 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
746 which can be overridden with --enable-global-attenuation
747 - EG fixes: made the length of "attack hold" stage more
748 accurate. Release stage can now start before attack stage
749 ends. Cancel release didn't work when sustain was zero. Attack
750 time now has a minimal value to prevent clicks.
751 - fixed pitch changes larger than one octave
752 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
753 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
754 all modes can be altered via standard GM messages, that is CC5 for
755 altering portamento time, CC65 for enabling / disabling portamento
756 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
757 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
758 parameter) and crossfade
759 - added support for the "attenuation controller threshold" gig
760 parameter
761 - added smoothing of volume changes caused by control change
762 messages
763 - sample loop parameters are now taken from the DimensionRegion
764 instead of the wave chunk
765 - fixed keyswitching for v3 gigs with a number of keyswitch splits
766 not equal to a power of two
767 - reimplementation of the filter algorithm. The new filter is more
768 accurate and supports all gig filter types, including bandreject
769 and lowpass turbo.
770 - real support for 24 bit samples - samples are not truncated to
771 16 bits anymore
772 - support for aftertouch (channel pressure, not polyphonic
773 aftertouch)
774 - LFO1 behaviour fixed (dampening from max volume instead of
775 amplifying from 0)
777 * LSCP server:
778 - fixed application exit on broken pipe error (fixes bug #20)
779 - fixed the notification messages delay due to lack of
780 network activity (fixes bug #26)
781 - fixed parser bug which occured on space(s) within device parameters
784 * audio driver:
785 - added aRts audio output driver (by no means RT safe)
787 * MIDI driver:
788 - fixed legacy sysex code which caused dispatching of MIDI SysEx
789 messages several times instead of once
790 - API extension for MIDI drivers which already supply exact time stamps
791 for events (i.e. for offline rendering based MIDI drivers)
792 - added checks for bad MIDI data
794 * linuxsampler application:
795 - show available sampler engine types on startup
797 * general changes:
798 - support for muting sampler channels and solo mode of the same, two new
799 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
800 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
801 introduced for this, the behavior is the same like on a mixer console
802 (patch by Grigor Iliev, a bit adjusted). Also added configure option
803 --enable-process-muted-channels which can be used to enable the
804 processing of muted channels.
805 - support for sostenuto pedal
806 - support for monitoring the total number of active voices
809 - fixed some memory management errors
810 - fixed some concurrency problems that could lead to crashes when
811 LSCP commands were executed
812 - fixed crash when instrument loading failed previously on the same
813 sampler channel (fixes bug #36)
815 Version 0.3.3 (15 July 2005)
817 * packaging changes:
818 - fixed compilation with gcc 4.0
820 * Gigasampler format engine:
821 - LFO preprocessing was performed even though the respective LFO was
822 disabled by the instrument patch (minor efficiency fix)
823 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
824 for volume ramp downs in the same fragment (needed for current voice
825 stealing implementation) then simply inform the user with a warning
826 about possible click sounds and reduce the volume ramp down
827 appropriately instead of cancelling the audio device connection
829 Version 0.3.2 (24 June 2005)
831 * packaging changes:
832 - updated autotools build files to compile on OS X
833 (conditional compilation of CoreMIDI and MidiShare drivers)
834 - hand-crafted assembly optimization code can be disabled with
835 './configure --disable-asm' (definitely not recommended)
836 - fixed 'make dist' rule to include all necessary files
837 - require automake (>= 1.5) for 'make -f Makefile.cvs'
838 (due to 'dist-bzip2' automake option)
840 * Gigasampler format engine:
841 - support for the gig parameters for "release velocity response" curves
842 - fine tuning of the EGADSR envelope
843 - volume of release triggered samples now depends on note-on velocity,
844 note length and gig parameter "release trigger decay" instead of
845 note-off velocity.
846 - revised voice stealing
847 (fixes crash and endless loop caused by voice stealing)
848 - don't reset scale tuning on instrument or audio output device change
849 - handle key group conflicts right at the beginning of each fragment
850 instead of when the respective voice is actually launched
851 (fixes undefined behavior if stolen voices belonged to a key group -
852 this case was followed by a "killed voice survived" error message)
853 - fixed minor issue with null/silence samples
854 (those stole voices even though they don't need a voice at all which
855 resulted in "voice stealing didn't work out" messages)
856 - don't reset volume, pan, pitch and MIDI controller values on
857 instrument or audio output device change
859 * LSCP server:
860 - fixed some crashes (patch by Grigor Iliev, fixes #19)
861 - fixed LSCP event "CHANNEL_INFO" notification
862 (e.g. did not notify on volume changes or MIDI program change events)
864 * linuxsampler application:
865 - added command line parameters --lscp-addr and --lscp-port to override
866 default IP address and port of LSCP server
868 Version 0.3.1 (24 May 2005)
870 * initial release
