23 iliev 2012 - Refactoring: moved the independent code from
24     the Gigasampler format engine to base classes
25 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
26     respective profiling code is currently broken
27 schoenebeck 2053 - Introduced support for optional environment variable

333 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
334     a pointer to the launched InstrumentEditor object
335 schoenebeck 1876 - added optional 3rd party user data parameter for following
336     liblinuxsampler C++ API methods: InstrumentEditor::Main(),

349 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
350     opposed to the LSCP specs
351 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
352     reflected the wrong value
353 persson 1644 - fixed a memory management bug in ASIO driver
354 persson 1748 - Makefile fix: JACK_CFLAGS wasn't used
355 persson 1777 - JACK: use jack_client_open instead of the deprecated
356 persson 1748 jack_client_new
357 iliev 1829 - added (experimental) CoreAudio driver
358 persson 1888 - applied old fixes to the ASIO driver that were included in the
359     previous binary release but accidentally never committed to CVS
360     (fixes #117)
361 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
362     win64)
363 persson 1895 - VST: added support for sample rate and buffer size changes
364     - VST: close editor (Fantasia) when the VST is removed
365 persson 1908 - VST: avoid opening Fantasia more than once for each VST instance
366     - VST: export main function as "main" on Linux too (fix for
367     energyXT)
368 persson 1917 - VST: changed number of output channels from one stereo to 16
369     stereo
370 persson 1922 - added channel routing, fxsends and midi maps to the settings
371     stored in the plugin state
372 schoenebeck 1930 - performance optimization of AudioChannel::MixTo() and
373     AudioChannel::CopyTo() methods using GCC vector exensions
374     (if available)
375 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
376     exception when getting parameters from a disconnected device
377 schoenebeck 1599
378 persson 1651 * MIDI driver:
379     - added JACK MIDI driver
380 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
381     want to (mis)use it for some purpose ("fixed" in all current MIDI
382     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
383 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
384 persson 1887 CoreMidi or AU
385 persson 1889 - fixed mingw-w64 compilation error in MME driver
386 persson 1924 - made program change handling in MIDI thread real-time safe by
387     moving the logic to a non-RT thread
388 persson 1951 - fixed minor memory leak in ALSA driver
389 persson 1651
390 schoenebeck 1604 * instruments database:
391 iliev 1603 - avoid time consuming samples scanning when adding instruments
392     to the instruments database
393 iliev 1727 - added support for handling lost files in the instruments database
394 iliev 1781 - Implemented option for adding instruments in separate directories
395     in the instruments database
396     (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
397 persson 1908 - work-around for missing fnmatch function on Windows to make
398     instrument database compilable
399 schoenebeck 1930 - added instrument database support on Windows
400     works with both standalone mode and VST plugin.
401     the instruments DB file is located in
402     %USERPROFILE%\.linuxsampler\instruments.db which allows different
403     databases for each windows user
404     if no DB is present it automatically creates the .linuxsampler subdir
405     and then creates an empty DB
406 persson 1943 - fixed recursive import, which was broken on Windows
407 iliev 1603
408 persson 1644 * Gigasampler format engine:
409     - fixed a memory leak that could happen when a channel was deleted
410     while notes were playing
411 persson 1646 - made it possible to load an instrument even if the audio thread
412     isn't running
413 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
414     enough for piano gigs with pedal noise samples
415 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
416     respective FX send MIDI controller was used
417 schoenebeck 1724 - added support for GM global device volume SysEx message
418 schoenebeck 1762 (can be selected at compile time to either apply globally to the
419     whole sampler [default] or only to the sampler channels that are
420     connected to the respective MIDI input port the SysEx message arrived
421     on)
422 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
423     sometimes wrongly killed in the same buffer, causing no sound to
424     be played
425 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
426     which is usally used to switch a part between chromatic sounds and
427     drumkit sounds (as opposed to their common default setting of MIDI
428     part 10 being a drumkit part and all other ones chromatic parts), in
429     LS however one can switch between the first 16 MIDI instrument maps
430     defined for the sampler
431 persson 1764 - made it possible to create multiple sample channels even if the
432     audio thread isn't running
433 persson 1844 - fixed crash when removing channel with active voices (#116)
434 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
435     un-cache the respective sample if it's really not used by any
436     sampler engine anymore
437     - re-cache samples in case they were changed by an instrument editor,
438     e.g. when a sample was added while playing (#82)
439 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
440     same time stamp as the voice's note-on event and occured both in the
441     same audio fragment cycle (fixes bug #112)
442 persson 1858 - added support for the "fine tune" and "pitch bend range"
443     instrument-level gig parameters
444     - fixed minor artifacts in pitch bend handling
445 schoenebeck 1860 - added support for GS Reset SysEx message
446 persson 1862 - allow gig files to use unlimited downward pitch shifting
447     - added a limit check for upward pitch shifting
448 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
449     note was silent
450 persson 1923 - fixed crash happening when a pitch bend event arrived at the
451     same time a new instrument was loading
452 persson 1644
453 schoenebeck 1687 * LSCP server:
454     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
455     react on MIDI data arriving on certain sampler channels (so far only
456     Note-On and Note-Off events are sent via this LSCP event)
457 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
458     react on MIDI data arriving on certain MIDI input devices (so far only
459     Note-On and Note-Off events are sent via this LSCP event)
460 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
461     SET DB_INSTRUMENT FILE_PATH
462 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
463     frontends to send MIDI messages to specific sampler channel
464     - added two additional fields to GET FILE INSTRUMENT INFO command -
465     KEY_BINDINGS and KEYSWITCH_BINDINGS
466 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
467     was incorrect
468 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
469 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
470     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
471     be triggered respectively
472     - added new LSCP command "SET STREAMS" to globally alter the maximum
473     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
474     which will be triggered respectively
475 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
476     a gigedit file dialog is opened)
477 iliev 1848 - close all connections when LSCPServer is deleted
478 iliev 1882 - hard close of all sockets on exit
479 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
480     driver
481 schoenebeck 1687
482 iliev 1761 * Bug fixes:
483     - fixed a crash which occurs when removing a sampler channel waiting
484     to start instrument loading after another channel
485 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
486     instrument loading in progress (bug #113)
487 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
488     instrument with PERSISTENT load mode
489 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
490     - fixed memory leaks when issuing the following LSCP commands:
491     GET AUDIO_OUTPUT_DRIVER INFO
492     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
493     GET MIDI_INPUT_DRIVER INFO
494     GET MIDI_INPUT_DRIVER_PARAMETER INFO
495     - fixed possible compilation error when sqlite is not present
496 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
497 iliev 1847 - fixed crash when changing the audio output device of a sampler
498     channel with loaded instrument and start playing notes
499 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
500 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
501     PowerPC, which probably could cause crashes on that platform
502 persson 1889 - fixed a memory management error which could cause a crash when a
503     plugin was unloaded
504 persson 1896 - bugfix: two private structs had the same name, which could cause
505     problems if the linker chose the wrong constructor
506 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
507     Windows
508 iliev 1761
509    
510 schoenebeck 1560 Version 0.5.1 (6 December 2007)
511 schoenebeck 1454
512     * packaging changes:
513     - added autoconf checks for pthread library
514     - added autoconf check for pthread bug found on certain NPTL-enabled
515     glibc versions (see Gentoo bug report #194076)
516 senoner 1502 - added autoconf checks for MS Windows
517 schoenebeck 1454
518 persson 1455 * general changes:
519     - bugfix: the thread used by an editor plugin didn't die when the
520     editor closed
521 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
522     out all the space. operator--() did not apply size_mask after
523     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
524     order to avoid problems with the _NonVolatileReader functions.
525     - bugfix: Stream.h: added a missing divide by BytesPerSample in
526     GetWriteSpace(). Since this function is currently only used in
527     the stream's qsort() compare function, it didn't trigger any
528     bugs.
529     - Resampler.h, Synthesizer.h: cubic interpolation now works in
530     24bit mode too. Faster method to read 24bit words on little
531     endian machines (x86): replaced 3 byte reads + shifts with a 1
532     unaligned 32bit read and shift
533     - experimental support for MS Windows (MIDI input via MME, AUDIO
534     output via ASIO)
535     - made handling of SIGINT signal (Ctrl-C) a bit more robust
536 iliev 1541 - support for monitoring the total number of active disk streams
537     (new LSCP commands: GET TOTAL_STREAM_COUNT,
538     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
539 persson 1455
540 senoner 1500 * AUDIO driver:
541 persson 1534 - added Windows ASIO low latency audio driver
542 senoner 1500
543 senoner 1485 * MIDI driver:
544 schoenebeck 1495 - added MME Windows MIDI driver
545 senoner 1485
546 schoenebeck 1471 * LSCP server:
547     - added support for Windows style path / filenames, however with
548     forward slash path separators instead of backslash
549     (i.e. "C:/foo/bar.gig")
550 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
551     apostrophes as well
552 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
553     "LIST FILE INSTRUMENTS <file>" and
554     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
555     about an arbitrary instrument file on the system where the sampler is
556     running on
557 schoenebeck 1471
558 schoenebeck 1424 Version 0.5.0 (15 October 2007)
559 schoenebeck 947
560 schoenebeck 1065 * packaging changes:
561 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
562     API header files anymore
563 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
564     the Doxygen API documentation (explicitly listed in Doxyfile.in)
565 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
566     capable to execute our autoconf environment, thus no need anymore
567     to maintain the compile time configuration file (osx/version.h) for
568     OSX manually (patch by Toshi Nagata)
569 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
570     parameters
571 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
572     C++ API header files, all implementation internal global definitions
573     are now in global_private.h
574     - atomic.h is not exposed to the C++ API anymore
575     - no need to include config.h anymore for using LS's API header files
576     - fixed warnings in API doc generation
577 schoenebeck 1065
578 schoenebeck 947 * general changes:
579     - replaced the old, confusing MIDI program change mechanism by a
580     flexible MIDI instrument mapper which allows to map arbitrary
581 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
582 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
583     loaded on the respective channel when such MIDI program change
584     messages arrive, beside that, each entry allows to define a life-time
585     strategy for the instrument, so the user can define whether the
586     instrument should i.e. be permanently loaded (to be able to switch
587     quickly among sounds) or i.e. loaded just on demand when the
588     respective program change arrives (to safe RAM space), as well as a
589     global volume factor for each entry, so the user can adjust the volume
590     dynamic of his mapped instrument collection without having to modify
591 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
592     MIDI instrument maps and assign each sampler channel individually
593     a certain map, so that i.e. separation of normal instruments and
594     drumkits is possible
595 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
596     MIDI instrument maps, MIDI instruments, FX sends, global volume.
597 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
598     due to a constant size RingBuffer FIFO which is now replaced by a
599     dynamic (unlimited) size std::list FIFO
600 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
601     output channels for being processed by external effect processors
602     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
603     controllers
604 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
605 iliev 1130 - Implemented new, improved notification system
606 schoenebeck 1149 - fixed compilation errors regarding OSX
607     (patch by Toshi Nagata)
608 iliev 1161 - implemented instruments database
609 iliev 1345 - added support for escape sequences to the instruments database
610 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
611     within the sampler's process (by using instrument editor plugins),
612     you'll notice the new "Registered instrument editors:" message on
613 schoenebeck 1407 startup, added a new LSCP command:
614     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
615 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
616     given sampler channel, the plugin path can be overridden at compile
617     time with ./configure --enable-plugin-dir=/some/dir
618 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
619     in the sampler's process to safely edit instruments while playing
620     without a crash (hopefully) by either suspending single regions
621     wherever possible or if unavoidable whole engine(s)
622 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
623     policy and priority on thread level, set a minimum stack size for
624     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
625     threads simply inherited properties of starting thread instead of
626     setting their own policy and priority
627 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
628     main process did not wait for the stack trace process to finish
629     its output
630 persson 1248 - fixed some minor memory leaks
631 schoenebeck 1259 - reenabled assembly features support, at the moment only for
632     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
633 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
634     register, to avoid relocations in the text segment at runtime)
635 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
636 schoenebeck 947
637     * MIDI driver:
638     - dispatch bank select (MSB and LSB) messages
639    
640 schoenebeck 1049 * audio driver:
641     - the ALSA audio output driver parameters now reflect the correct
642     parameter value ranges for the respective selected sound card
643     (patch by Till Wimmer, a bit fixed and extended)
644    
645 persson 951 * Gigasampler format engine:
646     - if a filter is used and EG2 finishes before EG1, let the voice
647     die when EG2 has finished (this fixes a problem with clicks and
648     voice starvation for some gigs)
649 persson 1038 - playback is no longer disabled during instrument loading
650     - all notes playing on a channel that changes its instrument keep
651     playing with the old instrument until they get a note off
652     command
653 persson 1039 - EG fix: a release value of zero could cause noises or crash
654 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
655 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
656     above max sustain level, which means that there is a decay phase
657     even if sustain is 100%
658 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
659     noises or crashes
660 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
661 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
662     supplied to the configure script (fixes #46)
663 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
664     instead of a fix value
665 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
666     127 (solo mode) only kill voices if the respective mode really
667     changed
668 persson 951
669 schoenebeck 1244 * LSCP server:
670     - fixed compile time error for old Bison versions
671     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
672 schoenebeck 1245 - parser now supports extended ASCII character set
673     (up to ASCII code 255, i.e. includes now umlauts and accents)
674     - filename arguments in LSCP commands now allow to use escape
675     sequences, that is directly literal as one of: \', \", \\, \n, \r,
676     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
677     code value like \xf2) (fixes bug #24)
678 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
679     least one of their text-based parameters (i.e. name, description):
680     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
681     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
682     "SET DB_INSTRUMENT_DIRECTORY NAME",
683     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
684     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
685     "FIND DB_INSTRUMENT_DIRECTORIES"
686 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
687     occured, the unexpected character and the actually expected, possible
688     character(s), the latter only if less than 5 possibilities)
689 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
690     settings
691 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
692     of strings were treated as being one string containing commas
693     (fixes #57)
694 schoenebeck 1244
695 iliev 959 * Bug fixes:
696     - fixed crash occurring on certain LSCP scripts (Bug 39)
697 persson 1038 - another thread safety fix for lscp "load engine" and "set
698     channel audio output device"
699 iliev 1283 - fixed a crash which occurs when reassigning the same engine
700     on a sampler channel with connected MIDI device
701 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
702     device connected to a sampler channel to number less then or equal
703     to the index of the port to which the sampler channel is connected.
704 iliev 1296 - The previous bindings were not been disconnected when altering
705     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
706     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
707 iliev 1297 - The active stream/voice count statistic was incorrect.
708 iliev 1298 - notification events were not been sent for some sampler
709     channel changes
710 iliev 1305 - added default min and max values to restrict the number of allowed
711     audio output channels and MIDI input ports
712 iliev 1306 - the connection to the PCM interface is now closed when destroying
713     an audio output device
714 schoenebeck 1332 - files with slash in their path or filename could not be loaded
715 iliev 959
716 schoenebeck 1221 * test cases:
717     - updated and fixed (haven't been touched in a while)
718    
719 schoenebeck 937 Version 0.4.0 (24 November 2006)
720 persson 696
721 schoenebeck 697 * packaging changes:
722 capela 868 - changed deprecated copyright attribute to license; added ldconfig
723     to post-(un)install steps; added devel package for liblinuxsampler;
724     to linuxsampler.spec (RPM)
725 schoenebeck 697 - install necessary development header files for allowing 3rd party
726     applications to link against liblinuxsampler
727     - liblinuxsampler's API documentation can be generated with 'make docs'
728     (Doxygen required)
729 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
730     implementation (currently either an integer math solution or a
731     di-harmonic approximation), automatic detection can be overriden
732     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
733     configure script argument though (mandatory for cross-compilation)
734 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
735     provided some on his own (as CXXFLAGS)
736 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI

738 schoenebeck 852 - added compile time options to allow disabling the various audio and
739     MIDI drivers
740 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
741     (patch by Ebrahim Mayat)
742 schoenebeck 697
743 persson 696 * Gigasampler format engine:
744 schoenebeck 738 - extensive synthesis optimization
745     (reimplementation of EGs and LFO(s), removed synthesis parameter
746     prerendering and the synthesis parameter matrix in general, splitting
747     each audio fragment into subfragments now where each subfragment uses
748 persson 830 constant pitch and filter coefficients. The volume coefficient is
749     linearly interpolated inside a subfragment, unless
750     --disable-interpolate-volume is set.)
751 persson 696 - fine tuning of the EG modulation parameters
752 persson 729 - improved filter cutoff calculation by adding support for the
753     following gig parameters: Cutoff freq (used when no cutoff
754     controller is defined), Control invert, Minimum cutoff, Velocity
755 persson 791 curve and Velocity range. The keyboard tracking now scales
756     cutoff frequency instead of resonance.
757 persson 877 - added support for gig parameter Resonance.
758 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
759 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
760     which can be overridden with --enable-global-attenuation
761 persson 783 - EG fixes: made the length of "attack hold" stage more
762     accurate. Release stage can now start before attack stage
763 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
764     time now has a minimal value to prevent clicks.
765 persson 799 - fixed pitch changes larger than one octave
766 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
767     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
768     all modes can be altered via standard GM messages, that is CC5 for
769     altering portamento time, CC65 for enabling / disabling portamento
770     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
771 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
772     parameter) and crossfade
773 persson 831 - added support for the "attenuation controller threshold" gig
774     parameter
775 persson 832 - added smoothing of volume changes caused by control change
776     messages
777 persson 865 - sample loop parameters are now taken from the DimensionRegion
778     instead of the wave chunk
779     - fixed keyswitching for v3 gigs with a number of keyswitch splits
780     not equal to a power of two
781 persson 877 - reimplementation of the filter algorithm. The new filter is more
782     accurate and supports all gig filter types, including bandreject
783     and lowpass turbo.
784 persson 903 - real support for 24 bit samples - samples are not truncated to
785     16 bits anymore
786     - support for aftertouch (channel pressure, not polyphonic
787     aftertouch)
788 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
789     amplifying from 0)
790 persson 696
791 schoenebeck 711 * LSCP server:
792     - fixed application exit on broken pipe error (fixes bug #20)
793 iliev 793 - fixed the notification messages delay due to lack of
794     network activity (fixes bug #26)
795 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
796     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
797 schoenebeck 711
798 schoenebeck 838 * audio driver:
799     - added aRts audio output driver (by no means RT safe)
800    
801 schoenebeck 775 * MIDI driver:
802     - fixed legacy sysex code which caused dispatching of MIDI SysEx
803     messages several times instead of once
804 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
805     for events (i.e. for offline rendering based MIDI drivers)
806 persson 922 - added checks for bad MIDI data
807 schoenebeck 775
808 schoenebeck 900 * linuxsampler application:
809     - show available sampler engine types on startup
810    
811 schoenebeck 705 * general changes:
812     - support for muting sampler channels and solo mode of the same, two new
813     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
814     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
815     introduced for this, the behavior is the same like on a mixer console
816 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
817     --enable-process-muted-channels which can be used to enable the
818     processing of muted channels.
819 iliev 777 - support for sostenuto pedal
820 iliev 779 - support for monitoring the total number of active voices
821 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
822     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
823 persson 835 - fixed some memory management errors
824 persson 841 - fixed some concurrency problems that could lead to crashes when
825     LSCP commands were executed
826 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
827     sampler channel (fixes bug #36)
828 schoenebeck 705
829 schoenebeck 692 Version 0.3.3 (15 July 2005)
830 schoenebeck 686
831     * packaging changes:
832     - fixed compilation with gcc 4.0
833    
834 schoenebeck 687 * Gigasampler format engine:
835     - LFO preprocessing was performed even though the respective LFO was
836     disabled by the instrument patch (minor efficiency fix)
837 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
838     for volume ramp downs in the same fragment (needed for current voice
839     stealing implementation) then simply inform the user with a warning
840     about possible click sounds and reduce the volume ramp down
841     appropriately instead of cancelling the audio device connection
842 schoenebeck 687
843 schoenebeck 677 Version 0.3.2 (24 June 2005)
844 schoenebeck 609
845     * packaging changes:
846     - updated autotools build files to compile on OS X
847     (conditional compilation of CoreMIDI and MidiShare drivers)
848 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
849     './configure --disable-asm' (definitely not recommended)
850 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
851     - require automake (>= 1.5) for 'make -f Makefile.cvs'
852     (due to 'dist-bzip2' automake option)
853 schoenebeck 649
854     * Gigasampler format engine:
855     - support for the gig parameters for "release velocity response" curves
856     - fine tuning of the EGADSR envelope
857     - volume of release triggered samples now depends on note-on velocity,
858     note length and gig parameter "release trigger decay" instead of
859     note-off velocity.
860 schoenebeck 663 - revised voice stealing
861     (fixes crash and endless loop caused by voice stealing)
862 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
863 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
864     instead of when the respective voice is actually launched
865     (fixes undefined behavior if stolen voices belonged to a key group -
866     this case was followed by a "killed voice survived" error message)
867 schoenebeck 669 - fixed minor issue with null/silence samples
868     (those stole voices even though they don't need a voice at all which
869     resulted in "voice stealing didn't work out" messages)
870 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
871     instrument or audio output device change
872 schoenebeck 654
873 schoenebeck 620 * LSCP server:
874 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
875 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
876 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
877 schoenebeck 609
878 schoenebeck 668 * linuxsampler application:
879     - added command line parameters --lscp-addr and --lscp-port to override
880     default IP address and port of LSCP server
881    
882 schoenebeck 579 Version 0.3.1 (24 May 2005)
883    
884     * initial release
