32 persson 2086 * general changes:
33 iliev 2012 - Refactoring: moved the independent code from
34     the Gigasampler format engine to base classes
35 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
36     respective profiling code is currently broken
37 schoenebeck 2053 - Introduced support for optional environment variable
38     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
39     where the sampler shall look for instrument editor plugins
40     (patch by Luis Garrido, slightly modified).
41 schoenebeck 2121 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
42     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
43     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
44     note (in this implementation of the sampler its simply hard routed to
45     the 1st effect send of the sampler channel, no matter what the actual
46     effect type is)
47     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
48     note (in this implementation of the sampler its simply hard routed to
49     the 2nd effect send of the sampler channel, no matter what the actual
50     effect type is)
51 schoenebeck 2124 - implemented support for internal LADSPA effects
52 schoenebeck 2140 - raised limit of program change queue from 100 to 512
53     (as suggested by Alex Stone)
54 iliev 2223 - implemented sine LFO, pulse LFO and saw LFO
55 iliev 2296 - experimental support for per voice equalization
56 iliev 2306 - added command line option --exec-after-init
57 schoenebeck 2330 - Introduced new C++ API method:
58     EngineChannel::InstrumentFileName(int index)
59     allowing to retrieve the whole list of files used for the loaded
60     instrument on an engine channel (a.k.a. part). Some GigaStudio
61     instruments for example are splitted over several files like
62     "Foo.gig", "Foo.gx01", "Foo.gx02", ...
63 schoenebeck 2375 - Added new C++ API method Sampler::GetGlobalMaxVoices().
64     - Added new C++ API method Sampler::GetGlobalMaxStreams().
65     - Added new C++ API method Sampler::SetGlobalMaxVoices().
66     - Added new C++ API method Sampler::SetGlobalMaxStreams().
67 schoenebeck 2377 - Various "const" and "restrict" optimizations.
68 persson 2382 - all engines: add pan CC value to instrument pan parameter before
69     applying panning, instead of using two separate pan functions in
70     series (#182)
71 persson 2427 - added a lock guard class for exception safe mutex handling and
72     used it everywhere appropriate
73 schoenebeck 2448 - Immediately apply scale tuning changes to active voices.
74     - Exposed scale tuning to C++ API (along to the already existing standard
75     SysEx way).
76 persson 2452 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
77     and broken for ppc64. (Seq_cst loads and stores are actually not
78     used in LS, so the bug wasn't noticable.)
79     - lsatomic.h: added ARMv7 support
80 iliev 2012
81 persson 2043 * Gigasampler format engine:
82     - implemented the "round robin keyboard" dimension

86     key
87 persson 2382 - bugfix: pitch LFO controller "internal+aftertouch" was broken
88     - bugfix: filter keyboard tracking was broken
89     - filter performance fix (an unnecessary copy was made of the
90     filter parameters in each sub fragment)
91     - handle special case when pan parameter in gig file has max or
92     min value
93 schoenebeck 2396 - Exclusive Groups: don't ever stop voices of the same note,
94     doesn't sound naturally with a drumkit

312     - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
313     the driver will automatically connect to other CoreMIDI clients' ports
314     (e.g. external MIDI devices being attached to the Mac)

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

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

488 persson 1748 jack_client_new
489 iliev 1829 - added (experimental) CoreAudio driver
490 persson 1888 - applied old fixes to the ASIO driver that were included in the
491     previous binary release but accidentally never committed to CVS
492     (fixes #117)
493 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
494     win64)

508     exception when getting parameters from a disconnected device
509 schoenebeck 1599
510 persson 1651 * MIDI driver:
511     - added JACK MIDI driver
512 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously

530     instrument database compilable
531 schoenebeck 1930 - added instrument database support on Windows
532     works with both standalone mode and VST plugin.
533     the instruments DB file is located in
534     %USERPROFILE%\.linuxsampler\instruments.db which allows different
535     databases for each windows user
536     if no DB is present it automatically creates the .linuxsampler subdir
537     and then creates an empty DB
538 persson 1943 - fixed recursive import, which was broken on Windows
539 iliev 1603
540 persson 1644 * Gigasampler format engine:
541     - fixed a memory leak that could happen when a channel was deleted

545 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
546     enough for piano gigs with pedal noise samples
547 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
548     respective FX send MIDI controller was used
549 schoenebeck 1724 - added support for GM global device volume SysEx message
550 schoenebeck 1762 (can be selected at compile time to either apply globally to the
551     whole sampler [default] or only to the sampler channels that are
552     connected to the respective MIDI input port the SysEx message arrived
553     on)
554 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
555     sometimes wrongly killed in the same buffer, causing no sound to
556     be played
557 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
558     which is usally used to switch a part between chromatic sounds and
559     drumkit sounds (as opposed to their common default setting of MIDI
560     part 10 being a drumkit part and all other ones chromatic parts), in
561     LS however one can switch between the first 16 MIDI instrument maps
562     defined for the sampler
563 persson 1764 - made it possible to create multiple sample channels even if the
564     audio thread isn't running
565 persson 1844 - fixed crash when removing channel with active voices (#116)
566 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
567     un-cache the respective sample if it's really not used by any
568     sampler engine anymore
569     - re-cache samples in case they were changed by an instrument editor,
570     e.g. when a sample was added while playing (#82)
571 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
572     same time stamp as the voice's note-on event and occured both in the
573     same audio fragment cycle (fixes bug #112)
574 persson 1858 - added support for the "fine tune" and "pitch bend range"
575     instrument-level gig parameters
576     - fixed minor artifacts in pitch bend handling
577 schoenebeck 1860 - added support for GS Reset SysEx message
578 persson 1862 - allow gig files to use unlimited downward pitch shifting
579     - added a limit check for upward pitch shifting
580 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
581     note was silent
582 persson 1923 - fixed crash happening when a pitch bend event arrived at the
583     same time a new instrument was loading
584 persson 1644
585 schoenebeck 1687 * LSCP server:
586     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
587     react on MIDI data arriving on certain sampler channels (so far only
588     Note-On and Note-Off events are sent via this LSCP event)
589 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
590     react on MIDI data arriving on certain MIDI input devices (so far only
591     Note-On and Note-Off events are sent via this LSCP event)
592 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
593     SET DB_INSTRUMENT FILE_PATH

595     frontends to send MIDI messages to specific sampler channel
596     - added two additional fields to GET FILE INSTRUMENT INFO command -
597     KEY_BINDINGS and KEYSWITCH_BINDINGS
598 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
599     was incorrect
600 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
601 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
602     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
603     be triggered respectively
604     - added new LSCP command "SET STREAMS" to globally alter the maximum
605     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
606     which will be triggered respectively
607 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
608     a gigedit file dialog is opened)
609 iliev 1848 - close all connections when LSCPServer is deleted
610 iliev 1882 - hard close of all sockets on exit

612     driver
613 schoenebeck 1687
614 iliev 1761 * Bug fixes:
615     - fixed a crash which occurs when removing a sampler channel waiting

628 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
629 iliev 1847 - fixed crash when changing the audio output device of a sampler
630     channel with loaded instrument and start playing notes
631 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
632 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
633     PowerPC, which probably could cause crashes on that platform
634 persson 1889 - fixed a memory management error which could cause a crash when a
635     plugin was unloaded
636 persson 1896 - bugfix: two private structs had the same name, which could cause

649 schoenebeck 1454
650 persson 1455 * general changes:
651     - bugfix: the thread used by an editor plugin didn't die when the
652     editor closed
653 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
654     out all the space. operator--() did not apply size_mask after
655     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
656     order to avoid problems with the _NonVolatileReader functions.
657     - bugfix: Stream.h: added a missing divide by BytesPerSample in
658     GetWriteSpace(). Since this function is currently only used in
659     the stream's qsort() compare function, it didn't trigger any
660     bugs.
661     - Resampler.h, Synthesizer.h: cubic interpolation now works in
662     24bit mode too. Faster method to read 24bit words on little
663     endian machines (x86): replaced 3 byte reads + shifts with a 1
664     unaligned 32bit read and shift

677 senoner 1485
678 schoenebeck 1471 * LSCP server:
679     - added support for Windows style path / filenames, however with
680     forward slash path separators instead of backslash
681     (i.e. "C:/foo/bar.gig")
682 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
683     apostrophes as well
684 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
685     "LIST FILE INSTRUMENTS <file>" and
686     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
687     about an arbitrary instrument file on the system where the sampler is
688     running on
689 schoenebeck 1471
690 schoenebeck 1424 Version 0.5.0 (15 October 2007)
691 schoenebeck 947

693 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
694     API header files anymore
695 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
696     the Doxygen API documentation (explicitly listed in Doxyfile.in)
697 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
698     capable to execute our autoconf environment, thus no need anymore
699     to maintain the compile time configuration file (osx/version.h) for
700     OSX manually (patch by Toshi Nagata)
701 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
702     parameters
703 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
704     C++ API header files, all implementation internal global definitions
705     are now in global_private.h
706     - atomic.h is not exposed to the C++ API anymore
707     - no need to include config.h anymore for using LS's API header files
708     - fixed warnings in API doc generation
709 schoenebeck 1065
710 schoenebeck 947 * general changes:
711     - replaced the old, confusing MIDI program change mechanism by a
712     flexible MIDI instrument mapper which allows to map arbitrary
713 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
714 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
715     loaded on the respective channel when such MIDI program change
716     messages arrive, beside that, each entry allows to define a life-time
717     strategy for the instrument, so the user can define whether the
718     instrument should i.e. be permanently loaded (to be able to switch
719     quickly among sounds) or i.e. loaded just on demand when the
720     respective program change arrives (to safe RAM space), as well as a
721     global volume factor for each entry, so the user can adjust the volume
722     dynamic of his mapped instrument collection without having to modify
723 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
724     MIDI instrument maps and assign each sampler channel individually
725     a certain map, so that i.e. separation of normal instruments and
726     drumkits is possible
727 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
728     MIDI instrument maps, MIDI instruments, FX sends, global volume.
729 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
730     due to a constant size RingBuffer FIFO which is now replaced by a
731     dynamic (unlimited) size std::list FIFO
732 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
733     output channels for being processed by external effect processors
734     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
735     controllers
736 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
737 iliev 1130 - Implemented new, improved notification system
738 schoenebeck 1149 - fixed compilation errors regarding OSX
739     (patch by Toshi Nagata)
740 iliev 1161 - implemented instruments database
741 iliev 1345 - added support for escape sequences to the instruments database
742 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
743     within the sampler's process (by using instrument editor plugins),
744     you'll notice the new "Registered instrument editors:" message on
745 schoenebeck 1407 startup, added a new LSCP command:
746     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
747 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
748     given sampler channel, the plugin path can be overridden at compile
749     time with ./configure --enable-plugin-dir=/some/dir
750 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
751     in the sampler's process to safely edit instruments while playing
752     without a crash (hopefully) by either suspending single regions
753     wherever possible or if unavoidable whole engine(s)
754 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
755     policy and priority on thread level, set a minimum stack size for
756     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
757     threads simply inherited properties of starting thread instead of
758     setting their own policy and priority
759 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
760     main process did not wait for the stack trace process to finish
761     its output
762 persson 1248 - fixed some minor memory leaks
763 schoenebeck 1259 - reenabled assembly features support, at the moment only for
764     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
765 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
766     register, to avoid relocations in the text segment at runtime)
767 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
768 schoenebeck 947
769     * MIDI driver:
770     - dispatch bank select (MSB and LSB) messages
771    
772 schoenebeck 1049 * audio driver:
773     - the ALSA audio output driver parameters now reflect the correct
774     parameter value ranges for the respective selected sound card
775     (patch by Till Wimmer, a bit fixed and extended)
776    
777 persson 951 * Gigasampler format engine:
778     - if a filter is used and EG2 finishes before EG1, let the voice
779     die when EG2 has finished (this fixes a problem with clicks and
780     voice starvation for some gigs)
781 persson 1038 - playback is no longer disabled during instrument loading
782     - all notes playing on a channel that changes its instrument keep
783     playing with the old instrument until they get a note off
784     command
785 persson 1039 - EG fix: a release value of zero could cause noises or crash
786 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
787 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
788     above max sustain level, which means that there is a decay phase
789     even if sustain is 100%
790 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
791     noises or crashes
792 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
793 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
794     supplied to the configure script (fixes #46)
795 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
796     instead of a fix value
797 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
798     127 (solo mode) only kill voices if the respective mode really
799     changed
800 persson 951
801 schoenebeck 1244 * LSCP server:
802     - fixed compile time error for old Bison versions
803     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
804 schoenebeck 1245 - parser now supports extended ASCII character set
805     (up to ASCII code 255, i.e. includes now umlauts and accents)
806     - filename arguments in LSCP commands now allow to use escape
807     sequences, that is directly literal as one of: \', \", \\, \n, \r,
808     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
809     code value like \xf2) (fixes bug #24)
810 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
811     least one of their text-based parameters (i.e. name, description):
812     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
813     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
814     "SET DB_INSTRUMENT_DIRECTORY NAME",
815     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
816     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
817     "FIND DB_INSTRUMENT_DIRECTORIES"
818 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
819     occured, the unexpected character and the actually expected, possible
820     character(s), the latter only if less than 5 possibilities)
821 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
822     settings
823 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
824     of strings were treated as being one string containing commas
825     (fixes #57)
826 schoenebeck 1244
827 iliev 959 * Bug fixes:
828     - fixed crash occurring on certain LSCP scripts (Bug 39)
829 persson 1038 - another thread safety fix for lscp "load engine" and "set
830     channel audio output device"
831 iliev 1283 - fixed a crash which occurs when reassigning the same engine
832     on a sampler channel with connected MIDI device
833 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
834     device connected to a sampler channel to number less then or equal
835     to the index of the port to which the sampler channel is connected.
836 iliev 1296 - The previous bindings were not been disconnected when altering
837     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
838     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
839 iliev 1297 - The active stream/voice count statistic was incorrect.
840 iliev 1298 - notification events were not been sent for some sampler
841     channel changes
842 iliev 1305 - added default min and max values to restrict the number of allowed
843     audio output channels and MIDI input ports
844 iliev 1306 - the connection to the PCM interface is now closed when destroying
845     an audio output device
846 schoenebeck 1332 - files with slash in their path or filename could not be loaded
847 iliev 959
848 schoenebeck 1221 * test cases:
849     - updated and fixed (haven't been touched in a while)
850    
851 schoenebeck 937 Version 0.4.0 (24 November 2006)
852 persson 696
853 schoenebeck 697 * packaging changes:
854 capela 868 - changed deprecated copyright attribute to license; added ldconfig
855     to post-(un)install steps; added devel package for liblinuxsampler;
856     to linuxsampler.spec (RPM)
857 schoenebeck 697 - install necessary development header files for allowing 3rd party
858     applications to link against liblinuxsampler
859     - liblinuxsampler's API documentation can be generated with 'make docs'
860     (Doxygen required)
861 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
862     implementation (currently either an integer math solution or a
863     di-harmonic approximation), automatic detection can be overriden
864     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
865     configure script argument though (mandatory for cross-compilation)
866 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
867     provided some on his own (as CXXFLAGS)
868 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
869     messages
870 schoenebeck 852 - added compile time options to allow disabling the various audio and
871     MIDI drivers
872 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
873     (patch by Ebrahim Mayat)
874 schoenebeck 697
875 persson 696 * Gigasampler format engine:
876 schoenebeck 738 - extensive synthesis optimization
877     (reimplementation of EGs and LFO(s), removed synthesis parameter
878     prerendering and the synthesis parameter matrix in general, splitting
879     each audio fragment into subfragments now where each subfragment uses
880 persson 830 constant pitch and filter coefficients. The volume coefficient is
881     linearly interpolated inside a subfragment, unless
882     --disable-interpolate-volume is set.)
883 persson 696 - fine tuning of the EG modulation parameters
884 persson 729 - improved filter cutoff calculation by adding support for the
885     following gig parameters: Cutoff freq (used when no cutoff
886     controller is defined), Control invert, Minimum cutoff, Velocity
887 persson 791 curve and Velocity range. The keyboard tracking now scales
888     cutoff frequency instead of resonance.
889 persson 877 - added support for gig parameter Resonance.
890 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
891 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
892     which can be overridden with --enable-global-attenuation
893 persson 783 - EG fixes: made the length of "attack hold" stage more
894     accurate. Release stage can now start before attack stage
895 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
896     time now has a minimal value to prevent clicks.
897 persson 799 - fixed pitch changes larger than one octave
898 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
899     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
900     all modes can be altered via standard GM messages, that is CC5 for
901     altering portamento time, CC65 for enabling / disabling portamento
902     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
903 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
904     parameter) and crossfade
905 persson 831 - added support for the "attenuation controller threshold" gig
906     parameter
907 persson 832 - added smoothing of volume changes caused by control change
908     messages
909 persson 865 - sample loop parameters are now taken from the DimensionRegion
910     instead of the wave chunk
911     - fixed keyswitching for v3 gigs with a number of keyswitch splits
912     not equal to a power of two
913 persson 877 - reimplementation of the filter algorithm. The new filter is more
914     accurate and supports all gig filter types, including bandreject
915     and lowpass turbo.
916 persson 903 - real support for 24 bit samples - samples are not truncated to
917     16 bits anymore
918     - support for aftertouch (channel pressure, not polyphonic
919     aftertouch)
920 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
921     amplifying from 0)
922 persson 696
923 schoenebeck 711 * LSCP server:
924     - fixed application exit on broken pipe error (fixes bug #20)
925 iliev 793 - fixed the notification messages delay due to lack of
926     network activity (fixes bug #26)
927 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
928     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
929 schoenebeck 711
930 schoenebeck 838 * audio driver:
931     - added aRts audio output driver (by no means RT safe)
932    
933 schoenebeck 775 * MIDI driver:
934     - fixed legacy sysex code which caused dispatching of MIDI SysEx
935     messages several times instead of once
936 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
937     for events (i.e. for offline rendering based MIDI drivers)
938 persson 922 - added checks for bad MIDI data
939 schoenebeck 775
940 schoenebeck 900 * linuxsampler application:
941     - show available sampler engine types on startup
942    
943 schoenebeck 705 * general changes:
944     - support for muting sampler channels and solo mode of the same, two new
945     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
946     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
947     introduced for this, the behavior is the same like on a mixer console
948 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
949     --enable-process-muted-channels which can be used to enable the
950     processing of muted channels.
951 iliev 777 - support for sostenuto pedal
952 iliev 779 - support for monitoring the total number of active voices
953 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
954     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
955 persson 835 - fixed some memory management errors
956 persson 841 - fixed some concurrency problems that could lead to crashes when
957     LSCP commands were executed
958 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
959     sampler channel (fixes bug #36)
960 schoenebeck 705
961 schoenebeck 692 Version 0.3.3 (15 July 2005)
962 schoenebeck 686
963     * packaging changes:
964     - fixed compilation with gcc 4.0
965    
966 schoenebeck 687 * Gigasampler format engine:
967     - LFO preprocessing was performed even though the respective LFO was
968     disabled by the instrument patch (minor efficiency fix)
969 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
970     for volume ramp downs in the same fragment (needed for current voice
971     stealing implementation) then simply inform the user with a warning
972     about possible click sounds and reduce the volume ramp down
973     appropriately instead of cancelling the audio device connection
974 schoenebeck 687
975 schoenebeck 677 Version 0.3.2 (24 June 2005)
976 schoenebeck 609
977     * packaging changes:
978     - updated autotools build files to compile on OS X
979     (conditional compilation of CoreMIDI and MidiShare drivers)
980 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
981     './configure --disable-asm' (definitely not recommended)
982 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
983     - require automake (>= 1.5) for 'make -f Makefile.cvs'
984     (due to 'dist-bzip2' automake option)
985 schoenebeck 649
986     * Gigasampler format engine:
987     - support for the gig parameters for "release velocity response" curves
988     - fine tuning of the EGADSR envelope
989     - volume of release triggered samples now depends on note-on velocity,
990     note length and gig parameter "release trigger decay" instead of
991     note-off velocity.
992 schoenebeck 663 - revised voice stealing
993     (fixes crash and endless loop caused by voice stealing)
994 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
995 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
996     instead of when the respective voice is actually launched
997     (fixes undefined behavior if stolen voices belonged to a key group -
998     this case was followed by a "killed voice survived" error message)
999 schoenebeck 669 - fixed minor issue with null/silence samples
1000     (those stole voices even though they don't need a voice at all which
1001     resulted in "voice stealing didn't work out" messages)
1002 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
1003     instrument or audio output device change
1004 schoenebeck 654
1005 schoenebeck 620 * LSCP server:
1006 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1007 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
1008 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
1009 schoenebeck 609
1010 schoenebeck 668 * linuxsampler application:
1011     - added command line parameters --lscp-addr and --lscp-port to override
1012     default IP address and port of LSCP server
1013    
1014 schoenebeck 579 Version 0.3.1 (24 May 2005)
1015    
1016     * initial release
