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

87     key
88 persson 2382 - bugfix: pitch LFO controller "internal+aftertouch" was broken
89     - bugfix: filter keyboard tracking was broken
90     - filter performance fix (an unnecessary copy was made of the
91     filter parameters in each sub fragment)
92     - handle special case when pan parameter in gig file has max or
93     min value
94 schoenebeck 2396 - Exclusive Groups: don't ever stop voices of the same note,
95     doesn't sound naturally with a drumkit
96 persson 2408 - fixed EG1 modulation when attack or release is zero

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

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

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

416 schoenebeck 1599
417 schoenebeck 1639 * packaging changes:

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

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

506     AudioChannel::CopyTo() methods using GCC vector exensions
507     (if available)
508 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
509     exception when getting parameters from a disconnected device
510 schoenebeck 1599
511 persson 1651 * MIDI driver:
512     - added JACK MIDI driver
513 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
514     want to (mis)use it for some purpose ("fixed" in all current MIDI
515     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
516 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
517 persson 1887 CoreMidi or AU

530 persson 1908 - work-around for missing fnmatch function on Windows to make
531     instrument database compilable
532 schoenebeck 1930 - added instrument database support on Windows
533     works with both standalone mode and VST plugin.
534     the instruments DB file is located in
535     %USERPROFILE%\.linuxsampler\instruments.db which allows different
536     databases for each windows user
537     if no DB is present it automatically creates the .linuxsampler subdir
538     and then creates an empty DB
539 persson 1943 - fixed recursive import, which was broken on Windows
540 iliev 1603
541 persson 1644 * Gigasampler format engine:
542     - fixed a memory leak that could happen when a channel was deleted

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

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

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

625     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
626     GET MIDI_INPUT_DRIVER INFO
627     GET MIDI_INPUT_DRIVER_PARAMETER INFO

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

639 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
640     Windows
641 iliev 1761

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

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

694 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
695     API header files anymore
696 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
697     the Doxygen API documentation (explicitly listed in Doxyfile.in)
698 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
699     capable to execute our autoconf environment, thus no need anymore
700     to maintain the compile time configuration file (osx/version.h) for
701     OSX manually (patch by Toshi Nagata)
702 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
703     parameters
704 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
705     C++ API header files, all implementation internal global definitions
706     are now in global_private.h
707     - atomic.h is not exposed to the C++ API anymore
708     - no need to include config.h anymore for using LS's API header files
709     - fixed warnings in API doc generation
710 schoenebeck 1065
711 schoenebeck 947 * general changes:
712     - replaced the old, confusing MIDI program change mechanism by a
713     flexible MIDI instrument mapper which allows to map arbitrary
714 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
715 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
716     loaded on the respective channel when such MIDI program change
717     messages arrive, beside that, each entry allows to define a life-time
718     strategy for the instrument, so the user can define whether the
719     instrument should i.e. be permanently loaded (to be able to switch
720     quickly among sounds) or i.e. loaded just on demand when the
721     respective program change arrives (to safe RAM space), as well as a
722     global volume factor for each entry, so the user can adjust the volume
723     dynamic of his mapped instrument collection without having to modify
724 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
725     MIDI instrument maps and assign each sampler channel individually
726     a certain map, so that i.e. separation of normal instruments and
727     drumkits is possible
728 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
729     MIDI instrument maps, MIDI instruments, FX sends, global volume.
730 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
731     due to a constant size RingBuffer FIFO which is now replaced by a
732     dynamic (unlimited) size std::list FIFO
733 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
734     output channels for being processed by external effect processors
735     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
736     controllers
737 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
738 iliev 1130 - Implemented new, improved notification system
739 schoenebeck 1149 - fixed compilation errors regarding OSX
740     (patch by Toshi Nagata)
741 iliev 1161 - implemented instruments database
742 iliev 1345 - added support for escape sequences to the instruments database
743 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
744     within the sampler's process (by using instrument editor plugins),
745     you'll notice the new "Registered instrument editors:" message on
746 schoenebeck 1407 startup, added a new LSCP command:
747     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
748 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
749     given sampler channel, the plugin path can be overridden at compile
750     time with ./configure --enable-plugin-dir=/some/dir
751 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
752     in the sampler's process to safely edit instruments while playing
753     without a crash (hopefully) by either suspending single regions
754     wherever possible or if unavoidable whole engine(s)
755 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
756     policy and priority on thread level, set a minimum stack size for
757     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
758     threads simply inherited properties of starting thread instead of
759     setting their own policy and priority
760 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
761     main process did not wait for the stack trace process to finish
762     its output
763 persson 1248 - fixed some minor memory leaks
764 schoenebeck 1259 - reenabled assembly features support, at the moment only for
765     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
766 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
767     register, to avoid relocations in the text segment at runtime)
768 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
769 schoenebeck 947
770     * MIDI driver:
771     - dispatch bank select (MSB and LSB) messages
772    
773 schoenebeck 1049 * audio driver:
774     - the ALSA audio output driver parameters now reflect the correct
775     parameter value ranges for the respective selected sound card
776     (patch by Till Wimmer, a bit fixed and extended)
777    
778 persson 951 * Gigasampler format engine:
779     - if a filter is used and EG2 finishes before EG1, let the voice
780     die when EG2 has finished (this fixes a problem with clicks and
781     voice starvation for some gigs)
782 persson 1038 - playback is no longer disabled during instrument loading
783     - all notes playing on a channel that changes its instrument keep
784     playing with the old instrument until they get a note off
785     command
786 persson 1039 - EG fix: a release value of zero could cause noises or crash
787 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
788 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
789     above max sustain level, which means that there is a decay phase
790     even if sustain is 100%
791 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
792     noises or crashes
793 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
794 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
795     supplied to the configure script (fixes #46)
796 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
797     instead of a fix value
798 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
799     127 (solo mode) only kill voices if the respective mode really
800     changed
801 persson 951
802 schoenebeck 1244 * LSCP server:
803     - fixed compile time error for old Bison versions
804     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
805 schoenebeck 1245 - parser now supports extended ASCII character set
806     (up to ASCII code 255, i.e. includes now umlauts and accents)
807     - filename arguments in LSCP commands now allow to use escape
808     sequences, that is directly literal as one of: \', \", \\, \n, \r,
809     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
810     code value like \xf2) (fixes bug #24)
811 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
812     least one of their text-based parameters (i.e. name, description):
813     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
814     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
815     "SET DB_INSTRUMENT_DIRECTORY NAME",
816     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
817     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
818     "FIND DB_INSTRUMENT_DIRECTORIES"
819 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
820     occured, the unexpected character and the actually expected, possible
821     character(s), the latter only if less than 5 possibilities)
822 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
823     settings
824 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
825     of strings were treated as being one string containing commas
826     (fixes #57)
827 schoenebeck 1244
828 iliev 959 * Bug fixes:
829     - fixed crash occurring on certain LSCP scripts (Bug 39)
830 persson 1038 - another thread safety fix for lscp "load engine" and "set
831     channel audio output device"
832 iliev 1283 - fixed a crash which occurs when reassigning the same engine
833     on a sampler channel with connected MIDI device
834 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
835     device connected to a sampler channel to number less then or equal
836     to the index of the port to which the sampler channel is connected.
837 iliev 1296 - The previous bindings were not been disconnected when altering
838     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
839     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
840 iliev 1297 - The active stream/voice count statistic was incorrect.
841 iliev 1298 - notification events were not been sent for some sampler
842     channel changes
843 iliev 1305 - added default min and max values to restrict the number of allowed
844     audio output channels and MIDI input ports
845 iliev 1306 - the connection to the PCM interface is now closed when destroying
846     an audio output device
847 schoenebeck 1332 - files with slash in their path or filename could not be loaded
848 iliev 959
849 schoenebeck 1221 * test cases:
850     - updated and fixed (haven't been touched in a while)
851    
852 schoenebeck 937 Version 0.4.0 (24 November 2006)
853 persson 696
854 schoenebeck 697 * packaging changes:
855 capela 868 - changed deprecated copyright attribute to license; added ldconfig
856     to post-(un)install steps; added devel package for liblinuxsampler;
857     to linuxsampler.spec (RPM)
858 schoenebeck 697 - install necessary development header files for allowing 3rd party
859     applications to link against liblinuxsampler
860     - liblinuxsampler's API documentation can be generated with 'make docs'
861     (Doxygen required)
862 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
863     implementation (currently either an integer math solution or a
864     di-harmonic approximation), automatic detection can be overriden
865     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
866     configure script argument though (mandatory for cross-compilation)
867 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
868     provided some on his own (as CXXFLAGS)
869 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
870     messages
871 schoenebeck 852 - added compile time options to allow disabling the various audio and
872     MIDI drivers
873 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
874     (patch by Ebrahim Mayat)
875 schoenebeck 697
876 persson 696 * Gigasampler format engine:
877 schoenebeck 738 - extensive synthesis optimization
878     (reimplementation of EGs and LFO(s), removed synthesis parameter
879     prerendering and the synthesis parameter matrix in general, splitting
880     each audio fragment into subfragments now where each subfragment uses
881 persson 830 constant pitch and filter coefficients. The volume coefficient is
882     linearly interpolated inside a subfragment, unless
883     --disable-interpolate-volume is set.)
884 persson 696 - fine tuning of the EG modulation parameters
885 persson 729 - improved filter cutoff calculation by adding support for the
886     following gig parameters: Cutoff freq (used when no cutoff
887     controller is defined), Control invert, Minimum cutoff, Velocity
888 persson 791 curve and Velocity range. The keyboard tracking now scales
889     cutoff frequency instead of resonance.
890 persson 877 - added support for gig parameter Resonance.
891 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
892 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
893     which can be overridden with --enable-global-attenuation
894 persson 783 - EG fixes: made the length of "attack hold" stage more
895     accurate. Release stage can now start before attack stage
896 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
897     time now has a minimal value to prevent clicks.
898 persson 799 - fixed pitch changes larger than one octave
899 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
900     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
901     all modes can be altered via standard GM messages, that is CC5 for
902     altering portamento time, CC65 for enabling / disabling portamento
903     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
904 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
905     parameter) and crossfade
906 persson 831 - added support for the "attenuation controller threshold" gig
907     parameter
908 persson 832 - added smoothing of volume changes caused by control change
909     messages
910 persson 865 - sample loop parameters are now taken from the DimensionRegion
911     instead of the wave chunk
912     - fixed keyswitching for v3 gigs with a number of keyswitch splits
913     not equal to a power of two
914 persson 877 - reimplementation of the filter algorithm. The new filter is more
915     accurate and supports all gig filter types, including bandreject
916     and lowpass turbo.
917 persson 903 - real support for 24 bit samples - samples are not truncated to
918     16 bits anymore
919     - support for aftertouch (channel pressure, not polyphonic
920     aftertouch)
921 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
922     amplifying from 0)
923 persson 696
924 schoenebeck 711 * LSCP server:
925     - fixed application exit on broken pipe error (fixes bug #20)
926 iliev 793 - fixed the notification messages delay due to lack of
927     network activity (fixes bug #26)
928 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
929     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
930 schoenebeck 711
931 schoenebeck 838 * audio driver:
932     - added aRts audio output driver (by no means RT safe)
933    
934 schoenebeck 775 * MIDI driver:
935     - fixed legacy sysex code which caused dispatching of MIDI SysEx
936     messages several times instead of once
937 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
938     for events (i.e. for offline rendering based MIDI drivers)
939 persson 922 - added checks for bad MIDI data
940 schoenebeck 775
941 schoenebeck 900 * linuxsampler application:
942     - show available sampler engine types on startup
943    
944 schoenebeck 705 * general changes:
945     - support for muting sampler channels and solo mode of the same, two new
946     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
947     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
948     introduced for this, the behavior is the same like on a mixer console
949 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
950     --enable-process-muted-channels which can be used to enable the
951     processing of muted channels.
952 iliev 777 - support for sostenuto pedal
953 iliev 779 - support for monitoring the total number of active voices
954 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
955     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
956 persson 835 - fixed some memory management errors
957 persson 841 - fixed some concurrency problems that could lead to crashes when
958     LSCP commands were executed
959 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
960     sampler channel (fixes bug #36)
961 schoenebeck 705
962 schoenebeck 692 Version 0.3.3 (15 July 2005)
963 schoenebeck 686
964     * packaging changes:
965     - fixed compilation with gcc 4.0
966    
967 schoenebeck 687 * Gigasampler format engine:
968     - LFO preprocessing was performed even though the respective LFO was
969     disabled by the instrument patch (minor efficiency fix)
970 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
971     for volume ramp downs in the same fragment (needed for current voice
972     stealing implementation) then simply inform the user with a warning
973     about possible click sounds and reduce the volume ramp down
974     appropriately instead of cancelling the audio device connection
975 schoenebeck 687
976 schoenebeck 677 Version 0.3.2 (24 June 2005)
977 schoenebeck 609
978     * packaging changes:
979     - updated autotools build files to compile on OS X
980     (conditional compilation of CoreMIDI and MidiShare drivers)
981 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
982     './configure --disable-asm' (definitely not recommended)
983 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
984     - require automake (>= 1.5) for 'make -f Makefile.cvs'
985     (due to 'dist-bzip2' automake option)
986 schoenebeck 649
987     * Gigasampler format engine:
988     - support for the gig parameters for "release velocity response" curves
989     - fine tuning of the EGADSR envelope
990     - volume of release triggered samples now depends on note-on velocity,
991     note length and gig parameter "release trigger decay" instead of
992     note-off velocity.
993 schoenebeck 663 - revised voice stealing
994     (fixes crash and endless loop caused by voice stealing)
995 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
996 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
997     instead of when the respective voice is actually launched
998     (fixes undefined behavior if stolen voices belonged to a key group -
999     this case was followed by a "killed voice survived" error message)
1000 schoenebeck 669 - fixed minor issue with null/silence samples
1001     (those stole voices even though they don't need a voice at all which
1002     resulted in "voice stealing didn't work out" messages)
1003 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
1004     instrument or audio output device change
1005 schoenebeck 654
1006 schoenebeck 620 * LSCP server:
1007 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1008 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
1009 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
1010 schoenebeck 609
1011 schoenebeck 668 * linuxsampler application:
1012     - added command line parameters --lscp-addr and --lscp-port to override
1013     default IP address and port of LSCP server
1014    
1015 schoenebeck 579 Version 0.3.1 (24 May 2005)
1016    
1017     * initial release
