271 * Bug fixes:
272 - Fixed crash which may occur when MIDI key + transpose is out of range
273 - minor valgrind fixes
274 - fixed crash which occurred when changing an already deployed sampler
275 channel to a different engine type
276 - fixed crash when deleting a sampler channel or changing engine
277 type while an instrument load was in progress
278 - bugfix: playing a note while changing the instrument could cause
279 a crash, or give "Handing back unknown region" error messages
280 - bugfix: calling SET VOICES (which Fantasia does on start and
281 refresh) could cause instruments to be unloaded
282 - Mac OS X: fixed name collision of enum in EffectControl and
283 wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
284 - Mac OS X: fixed hanging threads
285 - Windows: disabled the previous thread fix on non-Mac systems, as
286 it caused hanging threads on Windows
287 - Fixed possible crashes due to corrupted MIDI/audio device list
288 after MIDI/audio device creation failure
289 - When creating MIDI instrument map entries with "PERSISTENT" type, the
290 instruments were uselessly precached with zero samples, however it still
291 took the full preloading time and on 1st program change the respective
292 instrument was completely reloaded again.
293 - fixed handling of rapid bank select and program change messages
294 sent to the same sampler channel (patch from the Open Octave
295 project, slightly adjusted)
296 - fixed crash when trying to create an effect instance with controls
297 which min and/or max values depend on the sample rate
299 Version 1.0.0 (31 July 2009)
301 * packaging changes:
302 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
303 causing e.g. the libgig test to fail when
304 "./configure --disable-jack-driver" was used
305 (patch by Alexis Ballier)
306 - fixed compilation with gcc 4.3
307 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)

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