File size: 54020 byte(s)
* Added support for multiple MIDI input ports per sampler channel (added
  various new C++ API methods for this new feature/design, old C++ API
  methods are now marked as deprecated but should still provide full
  behavior backward compatibility).
* LSCP Network interface: Added the following new LSCP commands for the new
  feature mentioned above: "ADD CHANNEL MIDI_INPUT",
  "REMOVE CHANNEL MIDI_INPUT" and "LIST CHANNEL MIDI_INPUTS". As with the
  C++ API changes, the old LSCP commands for MIDI input management are now
  marked as deprecated, but are still there and should provide full behavior
  backward compatibility.
* New LSCP specification document (LSCP v1.6).
* AbstractEngine::GSCheckSum(): don't allocate memory on the stack (was
  unsafe and caused compilation error with old clang 2.x).
* Bumped version (1.0.0.svn25).

37 persson 2382
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)

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)

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 iliev 2012
94 persson 2043 * Gigasampler format engine:
95     - implemented the "round robin keyboard" dimension
96     - fixed round robin and random dimensions for cases when number of
97     dimension zones is not a power of two
98     - made round robin use a counter for each region instead of each

100 persson 2382 - bugfix: pitch LFO controller "internal+aftertouch" was broken
101     - bugfix: filter keyboard tracking was broken
102     - filter performance fix (an unnecessary copy was made of the
103     filter parameters in each sub fragment)
104     - handle special case when pan parameter in gig file has max or
105     min value
106 schoenebeck 2396 - Exclusive Groups: don't ever stop voices of the same note,
107     doesn't sound naturally with a drumkit

321 persson 2324 - MME: removed compiler warning
322 schoenebeck 2370 - CoreMIDI: implemented driver specific port parameter "CORE_MIDI_BINDINGS",
323     which allows to retrieve the list of CoreMIDI clients / ports and to connect

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

522     exception when getting parameters from a disconnected device
523 schoenebeck 1599
524 persson 1651 * MIDI driver:
525     - added JACK MIDI driver
526 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously

544     instrument database compilable
545 schoenebeck 1930 - added instrument database support on Windows
546     works with both standalone mode and VST plugin.
547     the instruments DB file is located in
548     %USERPROFILE%\.linuxsampler\instruments.db which allows different
549     databases for each windows user
550     if no DB is present it automatically creates the .linuxsampler subdir
551     and then creates an empty DB
552 persson 1943 - fixed recursive import, which was broken on Windows
553 iliev 1603
554 persson 1644 * Gigasampler format engine:

560     enough for piano gigs with pedal noise samples
561 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
562     respective FX send MIDI controller was used
563 schoenebeck 1724 - added support for GM global device volume SysEx message
564 schoenebeck 1762 (can be selected at compile time to either apply globally to the
565     whole sampler [default] or only to the sampler channels that are
566     connected to the respective MIDI input port the SysEx message arrived
567     on)
568 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
569     sometimes wrongly killed in the same buffer, causing no sound to
570     be played
571 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
572     which is usally used to switch a part between chromatic sounds and
573     drumkit sounds (as opposed to their common default setting of MIDI
574     part 10 being a drumkit part and all other ones chromatic parts), in
575     LS however one can switch between the first 16 MIDI instrument maps
576     defined for the sampler
577 persson 1764 - made it possible to create multiple sample channels even if the
578     audio thread isn't running
579 persson 1844 - fixed crash when removing channel with active voices (#116)
580 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only

582     sampler engine anymore
583     - re-cache samples in case they were changed by an instrument editor,
584     e.g. when a sample was added while playing (#82)
585 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
586     same time stamp as the voice's note-on event and occured both in the
587     same audio fragment cycle (fixes bug #112)
588 persson 1858 - added support for the "fine tune" and "pitch bend range"
589     instrument-level gig parameters
590     - fixed minor artifacts in pitch bend handling
591 schoenebeck 1860 - added support for GS Reset SysEx message
592 persson 1862 - allow gig files to use unlimited downward pitch shifting
593     - added a limit check for upward pitch shifting
594 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
595     note was silent
596 persson 1923 - fixed crash happening when a pitch bend event arrived at the
597     same time a new instrument was loading
598 persson 1644
599 schoenebeck 1687 * LSCP server:

602     Note-On and Note-Off events are sent via this LSCP event)
603 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
604     react on MIDI data arriving on certain MIDI input devices (so far only
605     Note-On and Note-Off events are sent via this LSCP event)
606 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
607     SET DB_INSTRUMENT FILE_PATH

609     frontends to send MIDI messages to specific sampler channel
610     - added two additional fields to GET FILE INSTRUMENT INFO command -
611     KEY_BINDINGS and KEYSWITCH_BINDINGS
612 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
613     was incorrect
614 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
615 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
616     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
617     be triggered respectively
618     - added new LSCP command "SET STREAMS" to globally alter the maximum
619     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
620     which will be triggered respectively
621 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
622     a gigedit file dialog is opened)
623 iliev 1848 - close all connections when LSCPServer is deleted
624 iliev 1882 - hard close of all sockets on exit

643 iliev 1847 - fixed crash when changing the audio output device of a sampler
644     channel with loaded instrument and start playing notes
645 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
646 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit

665     - bugfix: the thread used by an editor plugin didn't die when the
666     editor closed
667 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
668     out all the space. operator--() did not apply size_mask after
669     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
670     order to avoid problems with the _NonVolatileReader functions.
671     - bugfix: Stream.h: added a missing divide by BytesPerSample in
672     GetWriteSpace(). Since this function is currently only used in
673     the stream's qsort() compare function, it didn't trigger any
674     bugs.
675     - Resampler.h, Synthesizer.h: cubic interpolation now works in
676     24bit mode too. Faster method to read 24bit words on little
677     endian machines (x86): replaced 3 byte reads + shifts with a 1

694     forward slash path separators instead of backslash
695     (i.e. "C:/foo/bar.gig")
696 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
697     apostrophes as well
698 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
699     "LIST FILE INSTRUMENTS <file>" and
700     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
701     about an arbitrary instrument file on the system where the sampler is
702     running on

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