38 persson 2086 * general changes:
39 iliev 2012 - Refactoring: moved the independent code from
40     the Gigasampler format engine to base classes
41 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
42     respective profiling code is currently broken
43 schoenebeck 2053 - Introduced support for optional environment variable
44     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
45     where the sampler shall look for instrument editor plugins
46     (patch by Luis Garrido, slightly modified).
47 schoenebeck 2121 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
48     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
49     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
50     note (in this implementation of the sampler its simply hard routed to
51     the 1st effect send of the sampler channel, no matter what the actual
52     effect type is)
53     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
54     note (in this implementation of the sampler its simply hard routed to
55     the 2nd effect send of the sampler channel, no matter what the actual
56     effect type is)
57 schoenebeck 2124 - implemented support for internal LADSPA effects
58 schoenebeck 2140 - raised limit of program change queue from 100 to 512
59     (as suggested by Alex Stone)
60 iliev 2223 - implemented sine LFO, pulse LFO and saw LFO
61 iliev 2296 - experimental support for per voice equalization
62 iliev 2306 - added command line option --exec-after-init
63 schoenebeck 2330 - Introduced new C++ API method:
64     EngineChannel::InstrumentFileName(int index)
65     allowing to retrieve the whole list of files used for the loaded
66     instrument on an engine channel (a.k.a. part). Some GigaStudio
67     instruments for example are splitted over several files like
68     "Foo.gig", "Foo.gx01", "Foo.gx02", ...
69 schoenebeck 2375 - Added new C++ API method Sampler::GetGlobalMaxVoices().
70     - Added new C++ API method Sampler::GetGlobalMaxStreams().
71     - Added new C++ API method Sampler::SetGlobalMaxVoices().
72     - Added new C++ API method Sampler::SetGlobalMaxStreams().
73 schoenebeck 2377 - Various "const" and "restrict" optimizations.
74 persson 2382 - all engines: add pan CC value to instrument pan parameter before
75     applying panning, instead of using two separate pan functions in
76     series (#182)
77 persson 2427 - added a lock guard class for exception safe mutex handling and
78     used it everywhere appropriate
79 schoenebeck 2448 - Immediately apply scale tuning changes to active voices.
80     - Exposed scale tuning to C++ API (along to the already existing standard
81     SysEx way).
82 persson 2452 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
83     and broken for ppc64. (Seq_cst loads and stores are actually not
84     used in LS, so the bug wasn't noticable.)
85     - lsatomic.h: added ARMv7 support
86 schoenebeck 2500 - Added support for multiple MIDI input ports per sampler channel (and
87     added various new C++ methods for this new feature / design change, old
88     C++ API methods for managing SamplerChannel's MIDI inputs are now marked
89     as deprecated but are still there and should provide full behavior
90     backward compatibility).
91     - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
92     unsafe and caused compilation error with clang 2.x).
93 schoenebeck 2506 - Bugfix: only process the latest MIDI program change event.
94 iliev 2012
95 persson 2043 * Gigasampler format engine:
96     - implemented the "round robin keyboard" dimension
97     - fixed round robin and random dimensions for cases when number of
98     dimension zones is not a power of two
99     - made round robin use a counter for each region instead of each
100     key
101 persson 2382 - bugfix: pitch LFO controller "internal+aftertouch" was broken
102     - bugfix: filter keyboard tracking was broken
103     - filter performance fix (an unnecessary copy was made of the
104     filter parameters in each sub fragment)
105     - handle special case when pan parameter in gig file has max or
106     min value
107 schoenebeck 2396 - Exclusive Groups: don't ever stop voices of the same note,
108     doesn't sound naturally with a drumkit
109 persson 2408 - fixed EG1 modulation when attack or release is zero
110 persson 2043

285 persson 2165 - save engine type (gig, sfz or sf2) in plugin state
286     - VST: when opening Fantasia, look for both 32 and 64 bit Java on

303     - VST: fixed crashes on Linux Ardour and EnergyXT
304 persson 2354 - DSSI bugfix: it wasn't possible to change engine type. The MIDI

322 persson 2324 - MME: removed compiler warning
323 schoenebeck 2370 - CoreMIDI: implemented driver specific port parameter "CORE_MIDI_BINDINGS",
324     which allows to retrieve the list of CoreMIDI clients / ports and to connect
325     to them a la JACK, via the usual sampler APIs
326     - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
327     the driver will automatically connect to other CoreMIDI clients' ports
328     (e.g. external MIDI devices being attached to the Mac)
329 schoenebeck 2380 - added support for MIDI note on velocity filter
330 persson 2382 - CoreMIDI: fixed memory deallocation error

531     exception when getting parameters from a disconnected device
532 schoenebeck 1599
533 persson 1651 * MIDI driver:
534     - added JACK MIDI driver
535 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously

553     instrument database compilable
554 schoenebeck 1930 - added instrument database support on Windows
555     works with both standalone mode and VST plugin.
556     the instruments DB file is located in
557     %USERPROFILE%\.linuxsampler\instruments.db which allows different
558     databases for each windows user
559     if no DB is present it automatically creates the .linuxsampler subdir
560     and then creates an empty DB
561 persson 1943 - fixed recursive import, which was broken on Windows
562 iliev 1603
563 persson 1644 * Gigasampler format engine:

569     enough for piano gigs with pedal noise samples
570 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
571     respective FX send MIDI controller was used
572 schoenebeck 1724 - added support for GM global device volume SysEx message
573 schoenebeck 1762 (can be selected at compile time to either apply globally to the
574     whole sampler [default] or only to the sampler channels that are
575     connected to the respective MIDI input port the SysEx message arrived
576     on)
577 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
578     sometimes wrongly killed in the same buffer, causing no sound to
579     be played
580 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
581     which is usally used to switch a part between chromatic sounds and
582     drumkit sounds (as opposed to their common default setting of MIDI
583     part 10 being a drumkit part and all other ones chromatic parts), in
584     LS however one can switch between the first 16 MIDI instrument maps
585     defined for the sampler
586 persson 1764 - made it possible to create multiple sample channels even if the
587     audio thread isn't running
588 persson 1844 - fixed crash when removing channel with active voices (#116)

591     sampler engine anymore
592     - re-cache samples in case they were changed by an instrument editor,
593     e.g. when a sample was added while playing (#82)
594 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
595     same time stamp as the voice's note-on event and occured both in the
596     same audio fragment cycle (fixes bug #112)
597 persson 1858 - added support for the "fine tune" and "pitch bend range"
598     instrument-level gig parameters
599     - fixed minor artifacts in pitch bend handling

601 persson 1862 - allow gig files to use unlimited downward pitch shifting
602     - added a limit check for upward pitch shifting
603 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
604     note was silent
605 persson 1923 - fixed crash happening when a pitch bend event arrived at the
606     same time a new instrument was loading
607 persson 1644
608 schoenebeck 1687 * LSCP server:

610     react on MIDI data arriving on certain sampler channels (so far only
611     Note-On and Note-Off events are sent via this LSCP event)
612 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
613     react on MIDI data arriving on certain MIDI input devices (so far only
614     Note-On and Note-Off events are sent via this LSCP event)
615 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
616     SET DB_INSTRUMENT FILE_PATH

618     frontends to send MIDI messages to specific sampler channel
619     - added two additional fields to GET FILE INSTRUMENT INFO command -
620     KEY_BINDINGS and KEYSWITCH_BINDINGS
621 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
622     was incorrect
623 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
624 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
625     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
626     be triggered respectively
627     - added new LSCP command "SET STREAMS" to globally alter the maximum
628     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
629     which will be triggered respectively
630 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
631     a gigedit file dialog is opened)

674     - bugfix: the thread used by an editor plugin didn't die when the
675     editor closed
676 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
677     out all the space. operator--() did not apply size_mask after
678     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
679     order to avoid problems with the _NonVolatileReader functions.
680     - bugfix: Stream.h: added a missing divide by BytesPerSample in
681     GetWriteSpace(). Since this function is currently only used in
682     the stream's qsort() compare function, it didn't trigger any
683     bugs.
684     - Resampler.h, Synthesizer.h: cubic interpolation now works in
685     24bit mode too. Faster method to read 24bit words on little

703     forward slash path separators instead of backslash
704     (i.e. "C:/foo/bar.gig")
705 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
706     apostrophes as well
707 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
708     "LIST FILE INSTRUMENTS <file>" and
709     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
710     about an arbitrary instrument file on the system where the sampler is

713 schoenebeck 1424 Version 0.5.0 (15 October 2007)
714 schoenebeck 947
715 schoenebeck 1065 * packaging changes:
716 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
717     API header files anymore
718 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
719     the Doxygen API documentation (explicitly listed in Doxyfile.in)
720 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
721     capable to execute our autoconf environment, thus no need anymore
722     to maintain the compile time configuration file (osx/version.h) for
723     OSX manually (patch by Toshi Nagata)
724 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
725     parameters
726 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
727     C++ API header files, all implementation internal global definitions
728     are now in global_private.h
729     - atomic.h is not exposed to the C++ API anymore
730     - no need to include config.h anymore for using LS's API header files
731     - fixed warnings in API doc generation
732 schoenebeck 1065
733 schoenebeck 947 * general changes:
734     - replaced the old, confusing MIDI program change mechanism by a
735     flexible MIDI instrument mapper which allows to map arbitrary
736 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
737 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
738     loaded on the respective channel when such MIDI program change
739     messages arrive, beside that, each entry allows to define a life-time
740     strategy for the instrument, so the user can define whether the
741     instrument should i.e. be permanently loaded (to be able to switch
742     quickly among sounds) or i.e. loaded just on demand when the
743     respective program change arrives (to safe RAM space), as well as a
744     global volume factor for each entry, so the user can adjust the volume
745     dynamic of his mapped instrument collection without having to modify
746 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
747     MIDI instrument maps and assign each sampler channel individually
748     a certain map, so that i.e. separation of normal instruments and
749     drumkits is possible
750 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
751     MIDI instrument maps, MIDI instruments, FX sends, global volume.
752 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
753     due to a constant size RingBuffer FIFO which is now replaced by a
754     dynamic (unlimited) size std::list FIFO
755 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
756     output channels for being processed by external effect processors
757     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
758     controllers
759 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
760 iliev 1130 - Implemented new, improved notification system
761 schoenebeck 1149 - fixed compilation errors regarding OSX
762     (patch by Toshi Nagata)
763 iliev 1161 - implemented instruments database
764 iliev 1345 - added support for escape sequences to the instruments database
765 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
766     within the sampler's process (by using instrument editor plugins),
767     you'll notice the new "Registered instrument editors:" message on
768 schoenebeck 1407 startup, added a new LSCP command:
769     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
770 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
771     given sampler channel, the plugin path can be overridden at compile
772     time with ./configure --enable-plugin-dir=/some/dir
773 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
774     in the sampler's process to safely edit instruments while playing
775     without a crash (hopefully) by either suspending single regions
776     wherever possible or if unavoidable whole engine(s)
777 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
778     policy and priority on thread level, set a minimum stack size for
779     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
780     threads simply inherited properties of starting thread instead of
781     setting their own policy and priority
782 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
783     main process did not wait for the stack trace process to finish
784     its output
785 persson 1248 - fixed some minor memory leaks
786 schoenebeck 1259 - reenabled assembly features support, at the moment only for
787     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
788 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
789     register, to avoid relocations in the text segment at runtime)
790 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
791 schoenebeck 947
792     * MIDI driver:
793     - dispatch bank select (MSB and LSB) messages
794    
795 schoenebeck 1049 * audio driver:
796     - the ALSA audio output driver parameters now reflect the correct
797     parameter value ranges for the respective selected sound card
798     (patch by Till Wimmer, a bit fixed and extended)
799    
800 persson 951 * Gigasampler format engine:
801     - if a filter is used and EG2 finishes before EG1, let the voice
802     die when EG2 has finished (this fixes a problem with clicks and
803     voice starvation for some gigs)
804 persson 1038 - playback is no longer disabled during instrument loading
805     - all notes playing on a channel that changes its instrument keep
806     playing with the old instrument until they get a note off
807     command
808 persson 1039 - EG fix: a release value of zero could cause noises or crash
809 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
810 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
811     above max sustain level, which means that there is a decay phase
812     even if sustain is 100%
813 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
814     noises or crashes
815 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
816 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
817     supplied to the configure script (fixes #46)
818 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
819     instead of a fix value
820 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
821     127 (solo mode) only kill voices if the respective mode really
822     changed
823 persson 951
824 schoenebeck 1244 * LSCP server:
825     - fixed compile time error for old Bison versions
826     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
827 schoenebeck 1245 - parser now supports extended ASCII character set
828     (up to ASCII code 255, i.e. includes now umlauts and accents)
829     - filename arguments in LSCP commands now allow to use escape
830     sequences, that is directly literal as one of: \', \", \\, \n, \r,
831     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
832     code value like \xf2) (fixes bug #24)
833 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
834     least one of their text-based parameters (i.e. name, description):
835     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
836     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
837     "SET DB_INSTRUMENT_DIRECTORY NAME",
838     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
839     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
840     "FIND DB_INSTRUMENT_DIRECTORIES"
841 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
842     occured, the unexpected character and the actually expected, possible
843     character(s), the latter only if less than 5 possibilities)
844 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
845     settings
846 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
847     of strings were treated as being one string containing commas
848     (fixes #57)
849 schoenebeck 1244
850 iliev 959 * Bug fixes:
851     - fixed crash occurring on certain LSCP scripts (Bug 39)
852 persson 1038 - another thread safety fix for lscp "load engine" and "set
853     channel audio output device"
854 iliev 1283 - fixed a crash which occurs when reassigning the same engine
855     on a sampler channel with connected MIDI device
856 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
857     device connected to a sampler channel to number less then or equal
858     to the index of the port to which the sampler channel is connected.
859 iliev 1296 - The previous bindings were not been disconnected when altering
860     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
861     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
862 iliev 1297 - The active stream/voice count statistic was incorrect.
863 iliev 1298 - notification events were not been sent for some sampler
864     channel changes
865 iliev 1305 - added default min and max values to restrict the number of allowed
866     audio output channels and MIDI input ports
867 iliev 1306 - the connection to the PCM interface is now closed when destroying
868     an audio output device
869 schoenebeck 1332 - files with slash in their path or filename could not be loaded
870 iliev 959
871 schoenebeck 1221 * test cases:
872     - updated and fixed (haven't been touched in a while)
873    
874 schoenebeck 937 Version 0.4.0 (24 November 2006)
875 persson 696
876 schoenebeck 697 * packaging changes:
877 capela 868 - changed deprecated copyright attribute to license; added ldconfig
878     to post-(un)install steps; added devel package for liblinuxsampler;
879     to linuxsampler.spec (RPM)
880 schoenebeck 697 - install necessary development header files for allowing 3rd party
881     applications to link against liblinuxsampler
882     - liblinuxsampler's API documentation can be generated with 'make docs'
883     (Doxygen required)
884 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
885     implementation (currently either an integer math solution or a
886     di-harmonic approximation), automatic detection can be overriden
887     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
888     configure script argument though (mandatory for cross-compilation)
889 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
890     provided some on his own (as CXXFLAGS)
891 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
892     messages
893 schoenebeck 852 - added compile time options to allow disabling the various audio and
894     MIDI drivers
895 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
896     (patch by Ebrahim Mayat)
897 schoenebeck 697
898 persson 696 * Gigasampler format engine:
899 schoenebeck 738 - extensive synthesis optimization
900     (reimplementation of EGs and LFO(s), removed synthesis parameter
901     prerendering and the synthesis parameter matrix in general, splitting
902     each audio fragment into subfragments now where each subfragment uses
903 persson 830 constant pitch and filter coefficients. The volume coefficient is
904     linearly interpolated inside a subfragment, unless
905     --disable-interpolate-volume is set.)
906 persson 696 - fine tuning of the EG modulation parameters
907 persson 729 - improved filter cutoff calculation by adding support for the
908     following gig parameters: Cutoff freq (used when no cutoff
909     controller is defined), Control invert, Minimum cutoff, Velocity
910 persson 791 curve and Velocity range. The keyboard tracking now scales
911     cutoff frequency instead of resonance.
912 persson 877 - added support for gig parameter Resonance.
913 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
914 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
915     which can be overridden with --enable-global-attenuation
916 persson 783 - EG fixes: made the length of "attack hold" stage more
917     accurate. Release stage can now start before attack stage
918 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
919     time now has a minimal value to prevent clicks.
920 persson 799 - fixed pitch changes larger than one octave
921 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
922     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
923     all modes can be altered via standard GM messages, that is CC5 for
924     altering portamento time, CC65 for enabling / disabling portamento
925     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
926 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
927     parameter) and crossfade
928 persson 831 - added support for the "attenuation controller threshold" gig
929     parameter
930 persson 832 - added smoothing of volume changes caused by control change
931     messages
932 persson 865 - sample loop parameters are now taken from the DimensionRegion
933     instead of the wave chunk
934     - fixed keyswitching for v3 gigs with a number of keyswitch splits
935     not equal to a power of two
936 persson 877 - reimplementation of the filter algorithm. The new filter is more
937     accurate and supports all gig filter types, including bandreject
938     and lowpass turbo.
939 persson 903 - real support for 24 bit samples - samples are not truncated to
940     16 bits anymore
941     - support for aftertouch (channel pressure, not polyphonic
942     aftertouch)
943 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
944     amplifying from 0)
945 persson 696
946 schoenebeck 711 * LSCP server:
947     - fixed application exit on broken pipe error (fixes bug #20)
948 iliev 793 - fixed the notification messages delay due to lack of
949     network activity (fixes bug #26)
950 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
951     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
952 schoenebeck 711
953 schoenebeck 838 * audio driver:
954     - added aRts audio output driver (by no means RT safe)
955    
956 schoenebeck 775 * MIDI driver:
957     - fixed legacy sysex code which caused dispatching of MIDI SysEx
958     messages several times instead of once
959 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
960     for events (i.e. for offline rendering based MIDI drivers)
961 persson 922 - added checks for bad MIDI data
962 schoenebeck 775
963 schoenebeck 900 * linuxsampler application:
964     - show available sampler engine types on startup
965    
966 schoenebeck 705 * general changes:
967     - support for muting sampler channels and solo mode of the same, two new
968     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
969     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
970     introduced for this, the behavior is the same like on a mixer console
971 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
972     --enable-process-muted-channels which can be used to enable the
973     processing of muted channels.
974 iliev 777 - support for sostenuto pedal
975 iliev 779 - support for monitoring the total number of active voices
976 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
977     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
978 persson 835 - fixed some memory management errors
979 persson 841 - fixed some concurrency problems that could lead to crashes when
980     LSCP commands were executed
981 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
982     sampler channel (fixes bug #36)
983 schoenebeck 705
984 schoenebeck 692 Version 0.3.3 (15 July 2005)
985 schoenebeck 686
986     * packaging changes:
987     - fixed compilation with gcc 4.0
988    
989 schoenebeck 687 * Gigasampler format engine:
990     - LFO preprocessing was performed even though the respective LFO was
991     disabled by the instrument patch (minor efficiency fix)
992 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
993     for volume ramp downs in the same fragment (needed for current voice
994     stealing implementation) then simply inform the user with a warning
995     about possible click sounds and reduce the volume ramp down
996     appropriately instead of cancelling the audio device connection
997 schoenebeck 687
998 schoenebeck 677 Version 0.3.2 (24 June 2005)
999 schoenebeck 609
1000     * packaging changes:
1001     - updated autotools build files to compile on OS X
1002     (conditional compilation of CoreMIDI and MidiShare drivers)
1003 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
1004     './configure --disable-asm' (definitely not recommended)
1005 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
1006     - require automake (>= 1.5) for 'make -f Makefile.cvs'
1007     (due to 'dist-bzip2' automake option)
1008 schoenebeck 649
1009     * Gigasampler format engine:
1010     - support for the gig parameters for "release velocity response" curves
1011     - fine tuning of the EGADSR envelope
1012     - volume of release triggered samples now depends on note-on velocity,
1013     note length and gig parameter "release trigger decay" instead of
1014     note-off velocity.
1015 schoenebeck 663 - revised voice stealing
1016     (fixes crash and endless loop caused by voice stealing)
1017 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
1018 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
1019     instead of when the respective voice is actually launched
1020     (fixes undefined behavior if stolen voices belonged to a key group -
1021     this case was followed by a "killed voice survived" error message)
1022 schoenebeck 669 - fixed minor issue with null/silence samples
1023     (those stole voices even though they don't need a voice at all which
1024     resulted in "voice stealing didn't work out" messages)
1025 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
1026     instrument or audio output device change
1027 schoenebeck 654
1028 schoenebeck 620 * LSCP server:
1029 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1030 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
1031 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
1032 schoenebeck 609
1033 schoenebeck 668 * linuxsampler application:
1034     - added command line parameters --lscp-addr and --lscp-port to override
1035     default IP address and port of LSCP server
1036    
1037 schoenebeck 579 Version 0.3.1 (24 May 2005)
1038    
1039     * initial release
