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

87     dimension zones is not a power of two
88     - made round robin use a counter for each region instead of each
89     key
90 persson 2382 - bugfix: pitch LFO controller "internal+aftertouch" was broken
91     - bugfix: filter keyboard tracking was broken
92     - filter performance fix (an unnecessary copy was made of the
93     filter parameters in each sub fragment)
94     - handle special case when pan parameter in gig file has max or
95     min value
96 schoenebeck 2396 - Exclusive Groups: don't ever stop voices of the same note,
97     doesn't sound naturally with a drumkit
98 persson 2408 - fixed EG1 modulation when attack or release is zero
99 persson 2043

313     which allows to retrieve the list of CoreMIDI clients / ports and to connect
314     to them a la JACK, via the usual sampler APIs
315     - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
316     the driver will automatically connect to other CoreMIDI clients' ports
317     (e.g. external MIDI devices being attached to the Mac)
318 schoenebeck 2380 - added support for MIDI note on velocity filter

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

493 iliev 1829 - added (experimental) CoreAudio driver
494 persson 1888 - applied old fixes to the ASIO driver that were included in the
495     previous binary release but accidentally never committed to CVS

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

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

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

572     sampler engine anymore
573     - re-cache samples in case they were changed by an instrument editor,
574     e.g. when a sample was added while playing (#82)
575 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
576     same time stamp as the voice's note-on event and occured both in the
577     same audio fragment cycle (fixes bug #112)
578 persson 1858 - added support for the "fine tune" and "pitch bend range"
579     instrument-level gig parameters
580     - fixed minor artifacts in pitch bend handling
581 schoenebeck 1860 - added support for GS Reset SysEx message
582 persson 1862 - allow gig files to use unlimited downward pitch shifting
583     - added a limit check for upward pitch shifting
584 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
585     note was silent
586 persson 1923 - fixed crash happening when a pitch bend event arrived at the
587     same time a new instrument was loading
588 persson 1644
589 schoenebeck 1687 * LSCP server:
590     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
591     react on MIDI data arriving on certain sampler channels (so far only
592     Note-On and Note-Off events are sent via this LSCP event)
593 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
594     react on MIDI data arriving on certain MIDI input devices (so far only
595     Note-On and Note-Off events are sent via this LSCP event)
596 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
597     SET DB_INSTRUMENT FILE_PATH

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

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

656     editor closed
657 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
658     out all the space. operator--() did not apply size_mask after
659     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
660     order to avoid problems with the _NonVolatileReader functions.
661     - bugfix: Stream.h: added a missing divide by BytesPerSample in
662     GetWriteSpace(). Since this function is currently only used in
663     the stream's qsort() compare function, it didn't trigger any
664     bugs.
665     - Resampler.h, Synthesizer.h: cubic interpolation now works in
666     24bit mode too. Faster method to read 24bit words on little
667     endian machines (x86): replaced 3 byte reads + shifts with a 1

684     forward slash path separators instead of backslash
685     (i.e. "C:/foo/bar.gig")
686 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
687     apostrophes as well
688 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
689     "LIST FILE INSTRUMENTS <file>" and
690     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
691     about an arbitrary instrument file on the system where the sampler is
692     running on

700     the Doxygen API documentation (explicitly listed in Doxyfile.in)
701 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
702     capable to execute our autoconf environment, thus no need anymore
703     to maintain the compile time configuration file (osx/version.h) for
704     OSX manually (patch by Toshi Nagata)
705 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
706     parameters
707 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
708     C++ API header files, all implementation internal global definitions
709     are now in global_private.h
710     - atomic.h is not exposed to the C++ API anymore
711     - no need to include config.h anymore for using LS's API header files
712     - fixed warnings in API doc generation

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