27 persson 2382
28 persson 2086 * general changes:
29 iliev 2012 - Refactoring: moved the independent code from
30     the Gigasampler format engine to base classes
31 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
32     respective profiling code is currently broken
33 schoenebeck 2053 - Introduced support for optional environment variable
34     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
35     where the sampler shall look for instrument editor plugins
36     (patch by Luis Garrido, slightly modified).
37 schoenebeck 2121 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
38     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
39     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
40     note (in this implementation of the sampler its simply hard routed to
41     the 1st effect send of the sampler channel, no matter what the actual
42     effect type is)
43     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
44     note (in this implementation of the sampler its simply hard routed to
45     the 2nd effect send of the sampler channel, no matter what the actual
46     effect type is)
47 schoenebeck 2124 - implemented support for internal LADSPA effects
48 schoenebeck 2140 - raised limit of program change queue from 100 to 512

374     after MIDI/audio device creation failure
375 schoenebeck 2275 - When creating MIDI instrument map entries with "PERSISTENT" type, the

377     took the full preloading time and on 1st program change the respective
378     instrument was completely reloaded again.
379 persson 2277 - fixed handling of rapid bank select and program change messages

452     stacktrace mechanism seems to be broken on most systems at the moment)
453 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
454     a pointer to the launched InstrumentEditor object
455 schoenebeck 1876 - added optional 3rd party user data parameter for following

467     - removed the nonsense audio channel constraint (which was hard coded to
468     max. 100 audio channels) for most audio drivers
469 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
470     opposed to the LSCP specs

476 persson 1748 jack_client_new
477 iliev 1829 - added (experimental) CoreAudio driver
478 persson 1888 - applied old fixes to the ASIO driver that were included in the
479     previous binary release but accidentally never committed to CVS
480     (fixes #117)
481 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
482     win64)
483 persson 1895 - VST: added support for sample rate and buffer size changes
484     - VST: close editor (Fantasia) when the VST is removed

493     AudioChannel::CopyTo() methods using GCC vector exensions
494     (if available)
495 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
496     exception when getting parameters from a disconnected device
497 schoenebeck 1599
498 persson 1651 * MIDI driver:
499     - added JACK MIDI driver
500 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
501     want to (mis)use it for some purpose ("fixed" in all current MIDI
502     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
503 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
504 persson 1887 CoreMidi or AU
505 persson 1889 - fixed mingw-w64 compilation error in MME driver
506 persson 1924 - made program change handling in MIDI thread real-time safe by

517 persson 1908 - work-around for missing fnmatch function on Windows to make
518     instrument database compilable
519 schoenebeck 1930 - added instrument database support on Windows
520     works with both standalone mode and VST plugin.
521     the instruments DB file is located in
522     %USERPROFILE%\.linuxsampler\instruments.db which allows different
523     databases for each windows user
524     if no DB is present it automatically creates the .linuxsampler subdir
525     and then creates an empty DB
526 persson 1943 - fixed recursive import, which was broken on Windows
527 iliev 1603
528 persson 1644 * Gigasampler format engine:
529     - fixed a memory leak that could happen when a channel was deleted

532     isn't running
533 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
534     enough for piano gigs with pedal noise samples
535 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
536     respective FX send MIDI controller was used
537 schoenebeck 1724 - added support for GM global device volume SysEx message
538 schoenebeck 1762 (can be selected at compile time to either apply globally to the
539     whole sampler [default] or only to the sampler channels that are
540     connected to the respective MIDI input port the SysEx message arrived
541     on)
542 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
543     sometimes wrongly killed in the same buffer, causing no sound to
544     be played
545 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
546     which is usally used to switch a part between chromatic sounds and
547     drumkit sounds (as opposed to their common default setting of MIDI
548     part 10 being a drumkit part and all other ones chromatic parts), in
549     LS however one can switch between the first 16 MIDI instrument maps
550     defined for the sampler
551 persson 1764 - made it possible to create multiple sample channels even if the
552     audio thread isn't running
553 persson 1844 - fixed crash when removing channel with active voices (#116)
554 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
555     un-cache the respective sample if it's really not used by any
556     sampler engine anymore
557     - re-cache samples in case they were changed by an instrument editor,
558     e.g. when a sample was added while playing (#82)
559 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
560     same time stamp as the voice's note-on event and occured both in the
561     same audio fragment cycle (fixes bug #112)
562 persson 1858 - added support for the "fine tune" and "pitch bend range"
563     instrument-level gig parameters
564     - fixed minor artifacts in pitch bend handling
565 schoenebeck 1860 - added support for GS Reset SysEx message
566 persson 1862 - allow gig files to use unlimited downward pitch shifting
567     - added a limit check for upward pitch shifting
568 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
569     note was silent
570 persson 1923 - fixed crash happening when a pitch bend event arrived at the
571     same time a new instrument was loading
572 persson 1644
573 schoenebeck 1687 * LSCP server:
574     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
575     react on MIDI data arriving on certain sampler channels (so far only
576     Note-On and Note-Off events are sent via this LSCP event)
577 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
578     react on MIDI data arriving on certain MIDI input devices (so far only
579     Note-On and Note-Off events are sent via this LSCP event)
580 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
581     SET DB_INSTRUMENT FILE_PATH
582 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
583     frontends to send MIDI messages to specific sampler channel
584     - added two additional fields to GET FILE INSTRUMENT INFO command -
585     KEY_BINDINGS and KEYSWITCH_BINDINGS
586 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
587     was incorrect
588 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
589 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
590     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
591     be triggered respectively
592     - added new LSCP command "SET STREAMS" to globally alter the maximum
593     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
594     which will be triggered respectively
595 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
596     a gigedit file dialog is opened)
597 iliev 1848 - close all connections when LSCPServer is deleted
598 iliev 1882 - hard close of all sockets on exit
599 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
600     driver
601 schoenebeck 1687
602 iliev 1761 * Bug fixes:
603     - fixed a crash which occurs when removing a sampler channel waiting
604     to start instrument loading after another channel
605 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
606     instrument loading in progress (bug #113)
607 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
608     instrument with PERSISTENT load mode
609 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
610     - fixed memory leaks when issuing the following LSCP commands:
611     GET AUDIO_OUTPUT_DRIVER INFO
612     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
613     GET MIDI_INPUT_DRIVER INFO
614     GET MIDI_INPUT_DRIVER_PARAMETER INFO
615     - fixed possible compilation error when sqlite is not present
616 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
617 iliev 1847 - fixed crash when changing the audio output device of a sampler
618     channel with loaded instrument and start playing notes
619 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
620 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
621     PowerPC, which probably could cause crashes on that platform
622 persson 1889 - fixed a memory management error which could cause a crash when a
623     plugin was unloaded
624 persson 1896 - bugfix: two private structs had the same name, which could cause

626 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
627     Windows
628 iliev 1761

630 schoenebeck 1560 Version 0.5.1 (6 December 2007)
631 schoenebeck 1454
632     * packaging changes:
633     - added autoconf checks for pthread library
634     - added autoconf check for pthread bug found on certain NPTL-enabled
635     glibc versions (see Gentoo bug report #194076)
636 senoner 1502 - added autoconf checks for MS Windows
637 schoenebeck 1454
638 persson 1455 * general changes:
639     - bugfix: the thread used by an editor plugin didn't die when the
640     editor closed
641 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
642     out all the space. operator--() did not apply size_mask after
643     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
644     order to avoid problems with the _NonVolatileReader functions.
645     - bugfix: Stream.h: added a missing divide by BytesPerSample in
646     GetWriteSpace(). Since this function is currently only used in
647     the stream's qsort() compare function, it didn't trigger any
648     bugs.
649     - Resampler.h, Synthesizer.h: cubic interpolation now works in
650     24bit mode too. Faster method to read 24bit words on little
651     endian machines (x86): replaced 3 byte reads + shifts with a 1
652     unaligned 32bit read and shift
653     - experimental support for MS Windows (MIDI input via MME, AUDIO
654     output via ASIO)
655     - made handling of SIGINT signal (Ctrl-C) a bit more robust
656 iliev 1541 - support for monitoring the total number of active disk streams
657     (new LSCP commands: GET TOTAL_STREAM_COUNT,
658     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
659 persson 1455
660 senoner 1500 * AUDIO driver:
661 persson 1534 - added Windows ASIO low latency audio driver
662 senoner 1500
663 senoner 1485 * MIDI driver:
664 schoenebeck 1495 - added MME Windows MIDI driver
665 senoner 1485
666 schoenebeck 1471 * LSCP server:
667     - added support for Windows style path / filenames, however with
668     forward slash path separators instead of backslash
669     (i.e. "C:/foo/bar.gig")
670 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
671     apostrophes as well
672 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
673     "LIST FILE INSTRUMENTS <file>" and
674     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
675     about an arbitrary instrument file on the system where the sampler is
676     running on
677 schoenebeck 1471
678 schoenebeck 1424 Version 0.5.0 (15 October 2007)
679 schoenebeck 947
680 schoenebeck 1065 * packaging changes:
681 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
682     API header files anymore
683 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
684     the Doxygen API documentation (explicitly listed in Doxyfile.in)
685 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
686     capable to execute our autoconf environment, thus no need anymore
687     to maintain the compile time configuration file (osx/version.h) for
688     OSX manually (patch by Toshi Nagata)
689 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
690     parameters
691 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
692     C++ API header files, all implementation internal global definitions
693     are now in global_private.h
694     - atomic.h is not exposed to the C++ API anymore
695     - no need to include config.h anymore for using LS's API header files
696     - fixed warnings in API doc generation
697 schoenebeck 1065
698 schoenebeck 947 * general changes:
699     - replaced the old, confusing MIDI program change mechanism by a
700     flexible MIDI instrument mapper which allows to map arbitrary
701 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
702 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
703     loaded on the respective channel when such MIDI program change
704     messages arrive, beside that, each entry allows to define a life-time
705     strategy for the instrument, so the user can define whether the
706     instrument should i.e. be permanently loaded (to be able to switch
707     quickly among sounds) or i.e. loaded just on demand when the
708     respective program change arrives (to safe RAM space), as well as a
709     global volume factor for each entry, so the user can adjust the volume
710     dynamic of his mapped instrument collection without having to modify
711 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
712     MIDI instrument maps and assign each sampler channel individually
713     a certain map, so that i.e. separation of normal instruments and
714     drumkits is possible
715 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
716     MIDI instrument maps, MIDI instruments, FX sends, global volume.
717 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
718     due to a constant size RingBuffer FIFO which is now replaced by a
719     dynamic (unlimited) size std::list FIFO
720 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
721     output channels for being processed by external effect processors
722     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
723     controllers
724 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
725 iliev 1130 - Implemented new, improved notification system
726 schoenebeck 1149 - fixed compilation errors regarding OSX
727     (patch by Toshi Nagata)
728 iliev 1161 - implemented instruments database
729 iliev 1345 - added support for escape sequences to the instruments database
730 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
731     within the sampler's process (by using instrument editor plugins),
732     you'll notice the new "Registered instrument editors:" message on
733 schoenebeck 1407 startup, added a new LSCP command:
734     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
735 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
736     given sampler channel, the plugin path can be overridden at compile
737     time with ./configure --enable-plugin-dir=/some/dir
738 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
739     in the sampler's process to safely edit instruments while playing
740     without a crash (hopefully) by either suspending single regions
741     wherever possible or if unavoidable whole engine(s)
742 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
743     policy and priority on thread level, set a minimum stack size for
744     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
745     threads simply inherited properties of starting thread instead of
746     setting their own policy and priority
747 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
748     main process did not wait for the stack trace process to finish
749     its output
750 persson 1248 - fixed some minor memory leaks
751 schoenebeck 1259 - reenabled assembly features support, at the moment only for
752     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
753 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
754     register, to avoid relocations in the text segment at runtime)
755 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
756 schoenebeck 947
757     * MIDI driver:
758     - dispatch bank select (MSB and LSB) messages
759    
760 schoenebeck 1049 * audio driver:
761     - the ALSA audio output driver parameters now reflect the correct
762     parameter value ranges for the respective selected sound card
763     (patch by Till Wimmer, a bit fixed and extended)
764    
765 persson 951 * Gigasampler format engine:
766     - if a filter is used and EG2 finishes before EG1, let the voice
767     die when EG2 has finished (this fixes a problem with clicks and
768     voice starvation for some gigs)
769 persson 1038 - playback is no longer disabled during instrument loading
770     - all notes playing on a channel that changes its instrument keep
771     playing with the old instrument until they get a note off
772     command
773 persson 1039 - EG fix: a release value of zero could cause noises or crash
774 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
775 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
776     above max sustain level, which means that there is a decay phase
777     even if sustain is 100%
778 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
779     noises or crashes
780 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
781 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
782     supplied to the configure script (fixes #46)
783 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
784     instead of a fix value
785 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
786     127 (solo mode) only kill voices if the respective mode really
787     changed
788 persson 951
789 schoenebeck 1244 * LSCP server:
790     - fixed compile time error for old Bison versions
791     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
792 schoenebeck 1245 - parser now supports extended ASCII character set
793     (up to ASCII code 255, i.e. includes now umlauts and accents)
794     - filename arguments in LSCP commands now allow to use escape
795     sequences, that is directly literal as one of: \', \", \\, \n, \r,
796     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
797     code value like \xf2) (fixes bug #24)
798 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
799     least one of their text-based parameters (i.e. name, description):
800     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
801     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
802     "SET DB_INSTRUMENT_DIRECTORY NAME",
803     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
804     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
805     "FIND DB_INSTRUMENT_DIRECTORIES"
806 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
807     occured, the unexpected character and the actually expected, possible
808     character(s), the latter only if less than 5 possibilities)
809 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
810     settings
811 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
812     of strings were treated as being one string containing commas
813     (fixes #57)
814 schoenebeck 1244
815 iliev 959 * Bug fixes:
816     - fixed crash occurring on certain LSCP scripts (Bug 39)
817 persson 1038 - another thread safety fix for lscp "load engine" and "set
818     channel audio output device"
819 iliev 1283 - fixed a crash which occurs when reassigning the same engine
820     on a sampler channel with connected MIDI device
821 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
822     device connected to a sampler channel to number less then or equal
823     to the index of the port to which the sampler channel is connected.
824 iliev 1296 - The previous bindings were not been disconnected when altering
825     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
826     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
827 iliev 1297 - The active stream/voice count statistic was incorrect.
828 iliev 1298 - notification events were not been sent for some sampler
829     channel changes
830 iliev 1305 - added default min and max values to restrict the number of allowed
831     audio output channels and MIDI input ports
832 iliev 1306 - the connection to the PCM interface is now closed when destroying
833     an audio output device
834 schoenebeck 1332 - files with slash in their path or filename could not be loaded
835 iliev 959
836 schoenebeck 1221 * test cases:
837     - updated and fixed (haven't been touched in a while)
838    
839 schoenebeck 937 Version 0.4.0 (24 November 2006)
840 persson 696
841 schoenebeck 697 * packaging changes:
842 capela 868 - changed deprecated copyright attribute to license; added ldconfig
843     to post-(un)install steps; added devel package for liblinuxsampler;
844     to linuxsampler.spec (RPM)
845 schoenebeck 697 - install necessary development header files for allowing 3rd party
846     applications to link against liblinuxsampler
847     - liblinuxsampler's API documentation can be generated with 'make docs'
848     (Doxygen required)
849 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
850     implementation (currently either an integer math solution or a
851     di-harmonic approximation), automatic detection can be overriden
852     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
853     configure script argument though (mandatory for cross-compilation)
854 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
855     provided some on his own (as CXXFLAGS)
856 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
857     messages
858 schoenebeck 852 - added compile time options to allow disabling the various audio and
859     MIDI drivers
860 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
861     (patch by Ebrahim Mayat)
862 schoenebeck 697
863 persson 696 * Gigasampler format engine:
864 schoenebeck 738 - extensive synthesis optimization
865     (reimplementation of EGs and LFO(s), removed synthesis parameter
866     prerendering and the synthesis parameter matrix in general, splitting
867     each audio fragment into subfragments now where each subfragment uses
868 persson 830 constant pitch and filter coefficients. The volume coefficient is
869     linearly interpolated inside a subfragment, unless
870     --disable-interpolate-volume is set.)
871 persson 696 - fine tuning of the EG modulation parameters
872 persson 729 - improved filter cutoff calculation by adding support for the
873     following gig parameters: Cutoff freq (used when no cutoff
874     controller is defined), Control invert, Minimum cutoff, Velocity
875 persson 791 curve and Velocity range. The keyboard tracking now scales
876     cutoff frequency instead of resonance.
877 persson 877 - added support for gig parameter Resonance.
878 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
879 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
880     which can be overridden with --enable-global-attenuation
881 persson 783 - EG fixes: made the length of "attack hold" stage more
882     accurate. Release stage can now start before attack stage
883 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
884     time now has a minimal value to prevent clicks.
885 persson 799 - fixed pitch changes larger than one octave
886 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
887     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
888     all modes can be altered via standard GM messages, that is CC5 for
889     altering portamento time, CC65 for enabling / disabling portamento
890     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
891 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
892     parameter) and crossfade
893 persson 831 - added support for the "attenuation controller threshold" gig
894     parameter
895 persson 832 - added smoothing of volume changes caused by control change
896     messages
897 persson 865 - sample loop parameters are now taken from the DimensionRegion
898     instead of the wave chunk
899     - fixed keyswitching for v3 gigs with a number of keyswitch splits
900     not equal to a power of two
901 persson 877 - reimplementation of the filter algorithm. The new filter is more
902     accurate and supports all gig filter types, including bandreject
903     and lowpass turbo.
904 persson 903 - real support for 24 bit samples - samples are not truncated to
905     16 bits anymore
906     - support for aftertouch (channel pressure, not polyphonic
907     aftertouch)
908 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
909     amplifying from 0)
910 persson 696
911 schoenebeck 711 * LSCP server:
912     - fixed application exit on broken pipe error (fixes bug #20)
913 iliev 793 - fixed the notification messages delay due to lack of
914     network activity (fixes bug #26)
915 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
916     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
917 schoenebeck 711
918 schoenebeck 838 * audio driver:
919     - added aRts audio output driver (by no means RT safe)
920    
921 schoenebeck 775 * MIDI driver:
922     - fixed legacy sysex code which caused dispatching of MIDI SysEx
923     messages several times instead of once
924 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
925     for events (i.e. for offline rendering based MIDI drivers)
926 persson 922 - added checks for bad MIDI data
927 schoenebeck 775
928 schoenebeck 900 * linuxsampler application:
929     - show available sampler engine types on startup
930    
931 schoenebeck 705 * general changes:
932     - support for muting sampler channels and solo mode of the same, two new
933     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
934     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
935     introduced for this, the behavior is the same like on a mixer console
936 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
937     --enable-process-muted-channels which can be used to enable the
938     processing of muted channels.
939 iliev 777 - support for sostenuto pedal
940 iliev 779 - support for monitoring the total number of active voices
941 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
942     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
943 persson 835 - fixed some memory management errors
944 persson 841 - fixed some concurrency problems that could lead to crashes when
945     LSCP commands were executed
946 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
947     sampler channel (fixes bug #36)
948 schoenebeck 705
949 schoenebeck 692 Version 0.3.3 (15 July 2005)
950 schoenebeck 686
951     * packaging changes:
952     - fixed compilation with gcc 4.0
953    
954 schoenebeck 687 * Gigasampler format engine:
955     - LFO preprocessing was performed even though the respective LFO was
956     disabled by the instrument patch (minor efficiency fix)
957 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
958     for volume ramp downs in the same fragment (needed for current voice
959     stealing implementation) then simply inform the user with a warning
960     about possible click sounds and reduce the volume ramp down
961     appropriately instead of cancelling the audio device connection
962 schoenebeck 687
963 schoenebeck 677 Version 0.3.2 (24 June 2005)
964 schoenebeck 609
965     * packaging changes:
966     - updated autotools build files to compile on OS X
967     (conditional compilation of CoreMIDI and MidiShare drivers)
968 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
969     './configure --disable-asm' (definitely not recommended)
970 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
971     - require automake (>= 1.5) for 'make -f Makefile.cvs'
972     (due to 'dist-bzip2' automake option)
973 schoenebeck 649
974     * Gigasampler format engine:
975     - support for the gig parameters for "release velocity response" curves
976     - fine tuning of the EGADSR envelope
977     - volume of release triggered samples now depends on note-on velocity,
978     note length and gig parameter "release trigger decay" instead of
979     note-off velocity.
980 schoenebeck 663 - revised voice stealing
981     (fixes crash and endless loop caused by voice stealing)
982 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
983 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
984     instead of when the respective voice is actually launched
985     (fixes undefined behavior if stolen voices belonged to a key group -
986     this case was followed by a "killed voice survived" error message)
987 schoenebeck 669 - fixed minor issue with null/silence samples
988     (those stole voices even though they don't need a voice at all which
989     resulted in "voice stealing didn't work out" messages)
990 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
991     instrument or audio output device change
992 schoenebeck 654
993 schoenebeck 620 * LSCP server:
994 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
995 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
996 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
997 schoenebeck 609
998 schoenebeck 668 * linuxsampler application:
999     - added command line parameters --lscp-addr and --lscp-port to override
1000     default IP address and port of LSCP server
1001    
1002 schoenebeck 579 Version 0.3.1 (24 May 2005)
1003    
1004     * initial release
