* WIP: LSCP Shell: implemented support for auto-correction of       
  obvious and trivial LSCP syntax mistakes, support for
  auto-completion by tab key and visual completion suggestion
  while typing.

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)
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 schoenebeck 2515 - Introducing the LSCP shell, which provides convenient control of the
95     sampler from the command line by providing LSCP aware features.
96 iliev 2012
97 persson 2043 * Gigasampler format engine:
98     - implemented the "round robin keyboard" dimension
99     - fixed round robin and random dimensions for cases when number of
100     dimension zones is not a power of two
101     - made round robin use a counter for each region instead of each
102     key
103 persson 2382 - bugfix: pitch LFO controller "internal+aftertouch" was broken
104     - bugfix: filter keyboard tracking was broken
105     - filter performance fix (an unnecessary copy was made of the
106     filter parameters in each sub fragment)
107     - handle special case when pan parameter in gig file has max or
108     min value
109 schoenebeck 2396 - Exclusive Groups: don't ever stop voices of the same note,
110     doesn't sound naturally with a drumkit

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

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

538     exception when getting parameters from a disconnected device
539 schoenebeck 1599
540 persson 1651 * MIDI driver:
541     - added JACK MIDI driver
542 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously

560     instrument database compilable
561 schoenebeck 1930 - added instrument database support on Windows
562     works with both standalone mode and VST plugin.
563     the instruments DB file is located in
564     %USERPROFILE%\.linuxsampler\instruments.db which allows different

566     if no DB is present it automatically creates the .linuxsampler subdir
567     and then creates an empty DB

569 iliev 1603
570 persson 1644 * Gigasampler format engine:

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

598     sampler engine anymore
599     - re-cache samples in case they were changed by an instrument editor,
600     e.g. when a sample was added while playing (#82)
601 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
602     same time stamp as the voice's note-on event and occured both in the

604 persson 1858 - added support for the "fine tune" and "pitch bend range"
605     instrument-level gig parameters
606     - fixed minor artifacts in pitch bend handling

608 persson 1862 - allow gig files to use unlimited downward pitch shifting
609     - added a limit check for upward pitch shifting
610 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
611     note was silent
612 persson 1923 - fixed crash happening when a pitch bend event arrived at the
613     same time a new instrument was loading
614 persson 1644
615 schoenebeck 1687 * LSCP server:

617     react on MIDI data arriving on certain sampler channels (so far only
618     Note-On and Note-Off events are sent via this LSCP event)
619 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
620     react on MIDI data arriving on certain MIDI input devices (so far only
621     Note-On and Note-Off events are sent via this LSCP event)
622 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
623     SET DB_INSTRUMENT FILE_PATH

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

681     - bugfix: the thread used by an editor plugin didn't die when the
682     editor closed
683 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
684     out all the space. operator--() did not apply size_mask after
685     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
686     order to avoid problems with the _NonVolatileReader functions.
687     - bugfix: Stream.h: added a missing divide by BytesPerSample in
688     GetWriteSpace(). Since this function is currently only used in
689     the stream's qsort() compare function, it didn't trigger any
690     bugs.
691     - Resampler.h, Synthesizer.h: cubic interpolation now works in
692     24bit mode too. Faster method to read 24bit words on little
693     endian machines (x86): replaced 3 byte reads + shifts with a 1

710     forward slash path separators instead of backslash
711     (i.e. "C:/foo/bar.gig")
712 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
713     apostrophes as well
714 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
715     "LIST FILE INSTRUMENTS <file>" and
716     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
717     about an arbitrary instrument file on the system where the sampler is
718     running on
719 schoenebeck 1471
720 schoenebeck 1424 Version 0.5.0 (15 October 2007)
721 schoenebeck 947
722 schoenebeck 1065 * packaging changes:
723 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
724     API header files anymore
725 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
726     the Doxygen API documentation (explicitly listed in Doxyfile.in)
727 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
728     capable to execute our autoconf environment, thus no need anymore
729     to maintain the compile time configuration file (osx/version.h) for
730     OSX manually (patch by Toshi Nagata)
731 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
732     parameters
733 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
734     C++ API header files, all implementation internal global definitions
735     are now in global_private.h
736     - atomic.h is not exposed to the C++ API anymore
737     - no need to include config.h anymore for using LS's API header files
738     - fixed warnings in API doc generation
739 schoenebeck 1065
740 schoenebeck 947 * general changes:
741     - replaced the old, confusing MIDI program change mechanism by a
742     flexible MIDI instrument mapper which allows to map arbitrary
743 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
744 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
745     loaded on the respective channel when such MIDI program change
746     messages arrive, beside that, each entry allows to define a life-time
747     strategy for the instrument, so the user can define whether the
748     instrument should i.e. be permanently loaded (to be able to switch
749     quickly among sounds) or i.e. loaded just on demand when the
750     respective program change arrives (to safe RAM space), as well as a
751     global volume factor for each entry, so the user can adjust the volume
752     dynamic of his mapped instrument collection without having to modify
753 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
754     MIDI instrument maps and assign each sampler channel individually
755     a certain map, so that i.e. separation of normal instruments and
756     drumkits is possible
757 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
758     MIDI instrument maps, MIDI instruments, FX sends, global volume.
759 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
760     due to a constant size RingBuffer FIFO which is now replaced by a
761     dynamic (unlimited) size std::list FIFO
762 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
763     output channels for being processed by external effect processors
764     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
765     controllers
766 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
767 iliev 1130 - Implemented new, improved notification system
768 schoenebeck 1149 - fixed compilation errors regarding OSX
769     (patch by Toshi Nagata)
770 iliev 1161 - implemented instruments database
771 iliev 1345 - added support for escape sequences to the instruments database
772 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
773     within the sampler's process (by using instrument editor plugins),
774     you'll notice the new "Registered instrument editors:" message on
775 schoenebeck 1407 startup, added a new LSCP command:
776     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
777 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
778     given sampler channel, the plugin path can be overridden at compile
779     time with ./configure --enable-plugin-dir=/some/dir
780 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
781     in the sampler's process to safely edit instruments while playing
782     without a crash (hopefully) by either suspending single regions
783     wherever possible or if unavoidable whole engine(s)
784 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
785     policy and priority on thread level, set a minimum stack size for
786     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
787     threads simply inherited properties of starting thread instead of
788     setting their own policy and priority
789 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
790     main process did not wait for the stack trace process to finish
791     its output
792 persson 1248 - fixed some minor memory leaks
793 schoenebeck 1259 - reenabled assembly features support, at the moment only for
794     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
795 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
796     register, to avoid relocations in the text segment at runtime)
797 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
798 schoenebeck 947
799     * MIDI driver:
800     - dispatch bank select (MSB and LSB) messages
801    
802 schoenebeck 1049 * audio driver:
803     - the ALSA audio output driver parameters now reflect the correct
804     parameter value ranges for the respective selected sound card
805     (patch by Till Wimmer, a bit fixed and extended)
806    
807 persson 951 * Gigasampler format engine:
808     - if a filter is used and EG2 finishes before EG1, let the voice
809     die when EG2 has finished (this fixes a problem with clicks and
810     voice starvation for some gigs)
811 persson 1038 - playback is no longer disabled during instrument loading
812     - all notes playing on a channel that changes its instrument keep
813     playing with the old instrument until they get a note off
814     command
815 persson 1039 - EG fix: a release value of zero could cause noises or crash
816 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
817 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
818     above max sustain level, which means that there is a decay phase
819     even if sustain is 100%
820 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
821     noises or crashes
822 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
823 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
824     supplied to the configure script (fixes #46)
825 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
826     instead of a fix value
827 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
828     127 (solo mode) only kill voices if the respective mode really
829     changed
830 persson 951
831 schoenebeck 1244 * LSCP server:
832     - fixed compile time error for old Bison versions
833     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
834 schoenebeck 1245 - parser now supports extended ASCII character set
835     (up to ASCII code 255, i.e. includes now umlauts and accents)
836     - filename arguments in LSCP commands now allow to use escape
837     sequences, that is directly literal as one of: \', \", \\, \n, \r,
838     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
839     code value like \xf2) (fixes bug #24)
840 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
841     least one of their text-based parameters (i.e. name, description):
842     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
843     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
844     "SET DB_INSTRUMENT_DIRECTORY NAME",
845     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
846     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
847     "FIND DB_INSTRUMENT_DIRECTORIES"
848 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
849     occured, the unexpected character and the actually expected, possible
850     character(s), the latter only if less than 5 possibilities)
851 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
852     settings
853 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
854     of strings were treated as being one string containing commas
855     (fixes #57)
856 schoenebeck 1244
857 iliev 959 * Bug fixes:
858     - fixed crash occurring on certain LSCP scripts (Bug 39)
859 persson 1038 - another thread safety fix for lscp "load engine" and "set
860     channel audio output device"
861 iliev 1283 - fixed a crash which occurs when reassigning the same engine
862     on a sampler channel with connected MIDI device
863 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
864     device connected to a sampler channel to number less then or equal
865     to the index of the port to which the sampler channel is connected.
866 iliev 1296 - The previous bindings were not been disconnected when altering
867     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
868     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
869 iliev 1297 - The active stream/voice count statistic was incorrect.
870 iliev 1298 - notification events were not been sent for some sampler
871     channel changes
872 iliev 1305 - added default min and max values to restrict the number of allowed
873     audio output channels and MIDI input ports
874 iliev 1306 - the connection to the PCM interface is now closed when destroying
875     an audio output device
876 schoenebeck 1332 - files with slash in their path or filename could not be loaded
877 iliev 959
878 schoenebeck 1221 * test cases:
879     - updated and fixed (haven't been touched in a while)
880    
881 schoenebeck 937 Version 0.4.0 (24 November 2006)
882 persson 696
883 schoenebeck 697 * packaging changes:
884 capela 868 - changed deprecated copyright attribute to license; added ldconfig
885     to post-(un)install steps; added devel package for liblinuxsampler;
886     to linuxsampler.spec (RPM)
887 schoenebeck 697 - install necessary development header files for allowing 3rd party
888     applications to link against liblinuxsampler
889     - liblinuxsampler's API documentation can be generated with 'make docs'
890     (Doxygen required)
891 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
892     implementation (currently either an integer math solution or a
893     di-harmonic approximation), automatic detection can be overriden
894     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
895     configure script argument though (mandatory for cross-compilation)
896 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
897     provided some on his own (as CXXFLAGS)
898 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
899     messages
900 schoenebeck 852 - added compile time options to allow disabling the various audio and
901     MIDI drivers
902 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
903     (patch by Ebrahim Mayat)
904 schoenebeck 697
905 persson 696 * Gigasampler format engine:
906 schoenebeck 738 - extensive synthesis optimization
907     (reimplementation of EGs and LFO(s), removed synthesis parameter
908     prerendering and the synthesis parameter matrix in general, splitting
909     each audio fragment into subfragments now where each subfragment uses
910 persson 830 constant pitch and filter coefficients. The volume coefficient is
911     linearly interpolated inside a subfragment, unless
912     --disable-interpolate-volume is set.)
913 persson 696 - fine tuning of the EG modulation parameters
914 persson 729 - improved filter cutoff calculation by adding support for the
915     following gig parameters: Cutoff freq (used when no cutoff
916     controller is defined), Control invert, Minimum cutoff, Velocity
917 persson 791 curve and Velocity range. The keyboard tracking now scales
918     cutoff frequency instead of resonance.
919 persson 877 - added support for gig parameter Resonance.
920 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
921 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
922     which can be overridden with --enable-global-attenuation
923 persson 783 - EG fixes: made the length of "attack hold" stage more
924     accurate. Release stage can now start before attack stage
925 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
926     time now has a minimal value to prevent clicks.
927 persson 799 - fixed pitch changes larger than one octave
928 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
929     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
930     all modes can be altered via standard GM messages, that is CC5 for
931     altering portamento time, CC65 for enabling / disabling portamento
932     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
933 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
934     parameter) and crossfade
935 persson 831 - added support for the "attenuation controller threshold" gig
936     parameter
937 persson 832 - added smoothing of volume changes caused by control change
938     messages
939 persson 865 - sample loop parameters are now taken from the DimensionRegion
940     instead of the wave chunk
941     - fixed keyswitching for v3 gigs with a number of keyswitch splits
942     not equal to a power of two
943 persson 877 - reimplementation of the filter algorithm. The new filter is more
944     accurate and supports all gig filter types, including bandreject
945     and lowpass turbo.
946 persson 903 - real support for 24 bit samples - samples are not truncated to
947     16 bits anymore
948     - support for aftertouch (channel pressure, not polyphonic
949     aftertouch)
950 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
951     amplifying from 0)
952 persson 696
953 schoenebeck 711 * LSCP server:
954     - fixed application exit on broken pipe error (fixes bug #20)
955 iliev 793 - fixed the notification messages delay due to lack of
956     network activity (fixes bug #26)
957 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
958     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
959 schoenebeck 711
960 schoenebeck 838 * audio driver:
961     - added aRts audio output driver (by no means RT safe)
962    
963 schoenebeck 775 * MIDI driver:
964     - fixed legacy sysex code which caused dispatching of MIDI SysEx
965     messages several times instead of once
966 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
967     for events (i.e. for offline rendering based MIDI drivers)
968 persson 922 - added checks for bad MIDI data
969 schoenebeck 775
970 schoenebeck 900 * linuxsampler application:
971     - show available sampler engine types on startup
972    
973 schoenebeck 705 * general changes:
974     - support for muting sampler channels and solo mode of the same, two new
975     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
976     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
977     introduced for this, the behavior is the same like on a mixer console
978 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
979     --enable-process-muted-channels which can be used to enable the
980     processing of muted channels.
981 iliev 777 - support for sostenuto pedal
982 iliev 779 - support for monitoring the total number of active voices
983 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
984     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
985 persson 835 - fixed some memory management errors
986 persson 841 - fixed some concurrency problems that could lead to crashes when
987     LSCP commands were executed
988 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
989     sampler channel (fixes bug #36)
990 schoenebeck 705
991 schoenebeck 692 Version 0.3.3 (15 July 2005)
992 schoenebeck 686
993     * packaging changes:
994     - fixed compilation with gcc 4.0
995    
996 schoenebeck 687 * Gigasampler format engine:
997     - LFO preprocessing was performed even though the respective LFO was
998     disabled by the instrument patch (minor efficiency fix)
999 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1000     for volume ramp downs in the same fragment (needed for current voice
1001     stealing implementation) then simply inform the user with a warning
1002     about possible click sounds and reduce the volume ramp down
1003     appropriately instead of cancelling the audio device connection
1004 schoenebeck 687
1005 schoenebeck 677 Version 0.3.2 (24 June 2005)
1006 schoenebeck 609
1007     * packaging changes:
1008     - updated autotools build files to compile on OS X
1009     (conditional compilation of CoreMIDI and MidiShare drivers)
1010 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
1011     './configure --disable-asm' (definitely not recommended)
1012 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
1013     - require automake (>= 1.5) for 'make -f Makefile.cvs'
1014     (due to 'dist-bzip2' automake option)
1015 schoenebeck 649
1016     * Gigasampler format engine:
1017     - support for the gig parameters for "release velocity response" curves
1018     - fine tuning of the EGADSR envelope
1019     - volume of release triggered samples now depends on note-on velocity,
1020     note length and gig parameter "release trigger decay" instead of
1021     note-off velocity.
1022 schoenebeck 663 - revised voice stealing
1023     (fixes crash and endless loop caused by voice stealing)
1024 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
1025 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
1026     instead of when the respective voice is actually launched
1027     (fixes undefined behavior if stolen voices belonged to a key group -
1028     this case was followed by a "killed voice survived" error message)
1029 schoenebeck 669 - fixed minor issue with null/silence samples
1030     (those stole voices even though they don't need a voice at all which
1031     resulted in "voice stealing didn't work out" messages)
1032 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
1033     instrument or audio output device change
1034 schoenebeck 654
1035 schoenebeck 620 * LSCP server:
1036 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1037 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
1038 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
1039 schoenebeck 609
1040 schoenebeck 668 * linuxsampler application:
1041     - added command line parameters --lscp-addr and --lscp-port to override
1042     default IP address and port of LSCP server
1043    
1044 schoenebeck 579 Version 0.3.1 (24 May 2005)
1045    
1046     * initial release
