* Aftertouch: extended API to explicitly handle channel pressure and
  polyphonic key pressure events (so far polyphonic pressure was not
  supported at all, and channel pressure was rerouted as CC128 but not
  used so far).
* Gig Engine: Fixed support for 'aftertouch' attenuation controller.
* Bumped version (1.0.0.svn39).

40 persson 2382
41 persson 2086 * general changes:
42 iliev 2012 - Refactoring: moved the independent code from
43     the Gigasampler format engine to base classes
44 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
45     respective profiling code is currently broken
46 schoenebeck 2053 - Introduced support for optional environment variable
47     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
48     where the sampler shall look for instrument editor plugins
49     (patch by Luis Garrido, slightly modified).
50 schoenebeck 2121 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
51     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
52     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
53     note (in this implementation of the sampler its simply hard routed to
54     the 1st effect send of the sampler channel, no matter what the actual
55     effect type is)
56     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
57     note (in this implementation of the sampler its simply hard routed to
58     the 2nd effect send of the sampler channel, no matter what the actual
59     effect type is)
60 schoenebeck 2124 - implemented support for internal LADSPA effects
61 schoenebeck 2140 - raised limit of program change queue from 100 to 512
62     (as suggested by Alex Stone)
63 iliev 2223 - implemented sine LFO, pulse LFO and saw LFO
64 iliev 2296 - experimental support for per voice equalization
65 iliev 2306 - added command line option --exec-after-init
66 schoenebeck 2330 - Introduced new C++ API method:
67     EngineChannel::InstrumentFileName(int index)
68     allowing to retrieve the whole list of files used for the loaded
69     instrument on an engine channel (a.k.a. part). Some GigaStudio
70     instruments for example are splitted over several files like
71     "Foo.gig", "Foo.gx01", "Foo.gx02", ...
72 schoenebeck 2375 - Added new C++ API method Sampler::GetGlobalMaxVoices().
73     - Added new C++ API method Sampler::GetGlobalMaxStreams().
74     - Added new C++ API method Sampler::SetGlobalMaxVoices().
75     - Added new C++ API method Sampler::SetGlobalMaxStreams().
76 schoenebeck 2377 - Various "const" and "restrict" optimizations.
77 persson 2382 - all engines: add pan CC value to instrument pan parameter before
78     applying panning, instead of using two separate pan functions in
79     series (#182)
80 persson 2427 - added a lock guard class for exception safe mutex handling and
81     used it everywhere appropriate
82 schoenebeck 2448 - Immediately apply scale tuning changes to active voices.
83     - Exposed scale tuning to C++ API (along to the already existing standard
84     SysEx way).
85 persson 2452 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
86     and broken for ppc64. (Seq_cst loads and stores are actually not
87     used in LS, so the bug wasn't noticable.)
88     - lsatomic.h: added ARMv7 support
89 schoenebeck 2500 - Added support for multiple MIDI input ports per sampler channel (and
90     added various new C++ methods for this new feature / design change, old
91     C++ API methods for managing SamplerChannel's MIDI inputs are now marked
92     as deprecated but are still there and should provide full behavior
93     backward compatibility).
94     - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
95     unsafe and caused compilation error with clang 2.x).
96 schoenebeck 2506 - Bugfix: only process the latest MIDI program change event.
97 schoenebeck 2515 - Introducing the LSCP shell, which provides convenient control of the
98     sampler from the command line by providing LSCP aware features.
99 schoenebeck 2521 - VirtualMidiDevice: Added support for program change.
100     - VirtualMidiDevice: Added support for bank select (MSB & LSB).
101     - VirtualMidiDevice: Added support for pitch bend.
102 schoenebeck 2559 - Aftertouch: extended API to explicitly handle channel pressure and
103     polyphonic key pressure events (so far polyphonic pressure was not
104     supported at all, and channel pressure was rerouted as CC128 but not
105     used so far).
106 iliev 2012
107 persson 2043 * Gigasampler format engine:
108     - implemented the "round robin keyboard" dimension
109     - fixed round robin and random dimensions for cases when number of
110     dimension zones is not a power of two
111     - made round robin use a counter for each region instead of each
112     key
113 persson 2382 - bugfix: pitch LFO controller "internal+aftertouch" was broken
114     - bugfix: filter keyboard tracking was broken
115     - filter performance fix (an unnecessary copy was made of the
116     filter parameters in each sub fragment)
117     - handle special case when pan parameter in gig file has max or
118     min value
119 schoenebeck 2396 - Exclusive Groups: don't ever stop voices of the same note,
120     doesn't sound naturally with a drumkit

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

441     took the full preloading time and on 1st program change the respective
442     instrument was completely reloaded again.
443 persson 2277 - fixed handling of rapid bank select and program change messages
444     sent to the same sampler channel (patch from the Open Octave

466     (fixes #208)
467 schoenebeck 2523 - Fixed bug in LSCP grammar definition which caused a statement like
468     "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
469     practically irrelevant, however it caused problems with the new LSCP
470     shell's auto completion feature).

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

548 iliev 1829 - added (experimental) CoreAudio driver
549 persson 1888 - applied old fixes to the ASIO driver that were included in the
550     previous binary release but accidentally never committed to CVS
551     (fixes #117)
552 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on

589     instrument database compilable
590 schoenebeck 1930 - added instrument database support on Windows
591     works with both standalone mode and VST plugin.
592     the instruments DB file is located in
593     %USERPROFILE%\.linuxsampler\instruments.db which allows different

598 iliev 1603
599 persson 1644 * Gigasampler format engine:

604 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
605     enough for piano gigs with pedal noise samples
606 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
607     respective FX send MIDI controller was used
608 schoenebeck 1724 - added support for GM global device volume SysEx message
609 schoenebeck 1762 (can be selected at compile time to either apply globally to the

611     connected to the respective MIDI input port the SysEx message arrived
612     on)
613 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
614     sometimes wrongly killed in the same buffer, causing no sound to
615     be played
616 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
617     which is usally used to switch a part between chromatic sounds and
618     drumkit sounds (as opposed to their common default setting of MIDI
619     part 10 being a drumkit part and all other ones chromatic parts), in
620     LS however one can switch between the first 16 MIDI instrument maps
621     defined for the sampler
622 persson 1764 - made it possible to create multiple sample channels even if the
623     audio thread isn't running

627     sampler engine anymore
628     - re-cache samples in case they were changed by an instrument editor,
629     e.g. when a sample was added while playing (#82)
630 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
631     same time stamp as the voice's note-on event and occured both in the
632     same audio fragment cycle (fixes bug #112)
633 persson 1858 - added support for the "fine tune" and "pitch bend range"
634     instrument-level gig parameters
635     - fixed minor artifacts in pitch bend handling
636 schoenebeck 1860 - added support for GS Reset SysEx message
637 persson 1862 - allow gig files to use unlimited downward pitch shifting
638     - added a limit check for upward pitch shifting
639 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
640     note was silent
641 persson 1923 - fixed crash happening when a pitch bend event arrived at the
642     same time a new instrument was loading
643 persson 1644
644 schoenebeck 1687 * LSCP server:
645     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
646     react on MIDI data arriving on certain sampler channels (so far only
647     Note-On and Note-Off events are sent via this LSCP event)
648 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
649     react on MIDI data arriving on certain MIDI input devices (so far only
650     Note-On and Note-Off events are sent via this LSCP event)
651 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
652     SET DB_INSTRUMENT FILE_PATH

656     KEY_BINDINGS and KEYSWITCH_BINDINGS
657 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
658     was incorrect
659 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
660 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
661     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
662     be triggered respectively
663     - added new LSCP command "SET STREAMS" to globally alter the maximum
664     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
665     which will be triggered respectively
666 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
667     a gigedit file dialog is opened)
668 iliev 1848 - close all connections when LSCPServer is deleted
669 iliev 1882 - hard close of all sockets on exit

709 persson 1455 * general changes:
710     - bugfix: the thread used by an editor plugin didn't die when the
711     editor closed
712 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
713     out all the space. operator--() did not apply size_mask after
714     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
715     order to avoid problems with the _NonVolatileReader functions.
716     - bugfix: Stream.h: added a missing divide by BytesPerSample in
717     GetWriteSpace(). Since this function is currently only used in
718     the stream's qsort() compare function, it didn't trigger any
719     bugs.
720     - Resampler.h, Synthesizer.h: cubic interpolation now works in
721     24bit mode too. Faster method to read 24bit words on little
722     endian machines (x86): replaced 3 byte reads + shifts with a 1
723     unaligned 32bit read and shift
724     - experimental support for MS Windows (MIDI input via MME, AUDIO
725     output via ASIO)
726     - made handling of SIGINT signal (Ctrl-C) a bit more robust
727 iliev 1541 - support for monitoring the total number of active disk streams
728     (new LSCP commands: GET TOTAL_STREAM_COUNT,
729     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
730 persson 1455
731 senoner 1500 * AUDIO driver:
732 persson 1534 - added Windows ASIO low latency audio driver
733 senoner 1500
734 senoner 1485 * MIDI driver:
735 schoenebeck 1495 - added MME Windows MIDI driver
736 senoner 1485
737 schoenebeck 1471 * LSCP server:
738     - added support for Windows style path / filenames, however with
739     forward slash path separators instead of backslash
740     (i.e. "C:/foo/bar.gig")
741 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
742     apostrophes as well
743 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
744     "LIST FILE INSTRUMENTS <file>" and
745     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
746     about an arbitrary instrument file on the system where the sampler is
747     running on
748 schoenebeck 1471
749 schoenebeck 1424 Version 0.5.0 (15 October 2007)
750 schoenebeck 947
751 schoenebeck 1065 * packaging changes:
752 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
753     API header files anymore
754 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
755     the Doxygen API documentation (explicitly listed in Doxyfile.in)
756 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
757     capable to execute our autoconf environment, thus no need anymore
758     to maintain the compile time configuration file (osx/version.h) for
759     OSX manually (patch by Toshi Nagata)
760 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
761     parameters
762 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
763     C++ API header files, all implementation internal global definitions
764     are now in global_private.h
765     - atomic.h is not exposed to the C++ API anymore
766     - no need to include config.h anymore for using LS's API header files
767     - fixed warnings in API doc generation
768 schoenebeck 1065
769 schoenebeck 947 * general changes:
770     - replaced the old, confusing MIDI program change mechanism by a
771     flexible MIDI instrument mapper which allows to map arbitrary
772 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
773 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
774     loaded on the respective channel when such MIDI program change
775     messages arrive, beside that, each entry allows to define a life-time
776     strategy for the instrument, so the user can define whether the
777     instrument should i.e. be permanently loaded (to be able to switch
778     quickly among sounds) or i.e. loaded just on demand when the
779     respective program change arrives (to safe RAM space), as well as a
780     global volume factor for each entry, so the user can adjust the volume
781     dynamic of his mapped instrument collection without having to modify
782 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
783     MIDI instrument maps and assign each sampler channel individually
784     a certain map, so that i.e. separation of normal instruments and
785     drumkits is possible
786 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
787     MIDI instrument maps, MIDI instruments, FX sends, global volume.
788 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
789     due to a constant size RingBuffer FIFO which is now replaced by a
790     dynamic (unlimited) size std::list FIFO
791 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
792     output channels for being processed by external effect processors
793     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
794     controllers
795 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
796 iliev 1130 - Implemented new, improved notification system
797 schoenebeck 1149 - fixed compilation errors regarding OSX
798     (patch by Toshi Nagata)
799 iliev 1161 - implemented instruments database
800 iliev 1345 - added support for escape sequences to the instruments database
801 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
802     within the sampler's process (by using instrument editor plugins),
803     you'll notice the new "Registered instrument editors:" message on
804 schoenebeck 1407 startup, added a new LSCP command:
805     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
806 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
807     given sampler channel, the plugin path can be overridden at compile
808     time with ./configure --enable-plugin-dir=/some/dir
809 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
810     in the sampler's process to safely edit instruments while playing
811     without a crash (hopefully) by either suspending single regions
812     wherever possible or if unavoidable whole engine(s)
813 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
814     policy and priority on thread level, set a minimum stack size for
815     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
816     threads simply inherited properties of starting thread instead of
817     setting their own policy and priority
818 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
819     main process did not wait for the stack trace process to finish
820     its output
821 persson 1248 - fixed some minor memory leaks
822 schoenebeck 1259 - reenabled assembly features support, at the moment only for
823     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
824 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
825     register, to avoid relocations in the text segment at runtime)
826 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
827 schoenebeck 947
828     * MIDI driver:
829     - dispatch bank select (MSB and LSB) messages
830    
831 schoenebeck 1049 * audio driver:
832     - the ALSA audio output driver parameters now reflect the correct
833     parameter value ranges for the respective selected sound card
834     (patch by Till Wimmer, a bit fixed and extended)
835    
836 persson 951 * Gigasampler format engine:
837     - if a filter is used and EG2 finishes before EG1, let the voice
838     die when EG2 has finished (this fixes a problem with clicks and
839     voice starvation for some gigs)
840 persson 1038 - playback is no longer disabled during instrument loading
841     - all notes playing on a channel that changes its instrument keep
842     playing with the old instrument until they get a note off
843     command
844 persson 1039 - EG fix: a release value of zero could cause noises or crash
845 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
846 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
847     above max sustain level, which means that there is a decay phase
848     even if sustain is 100%
849 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
850     noises or crashes
851 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
852 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
853     supplied to the configure script (fixes #46)
854 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
855     instead of a fix value
856 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
857     127 (solo mode) only kill voices if the respective mode really
858     changed
859 persson 951
860 schoenebeck 1244 * LSCP server:
861     - fixed compile time error for old Bison versions
862     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
863 schoenebeck 1245 - parser now supports extended ASCII character set
864     (up to ASCII code 255, i.e. includes now umlauts and accents)
865     - filename arguments in LSCP commands now allow to use escape
866     sequences, that is directly literal as one of: \', \", \\, \n, \r,
867     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
868     code value like \xf2) (fixes bug #24)
869 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
870     least one of their text-based parameters (i.e. name, description):
871     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
872     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
873     "SET DB_INSTRUMENT_DIRECTORY NAME",
874     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
875     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
876     "FIND DB_INSTRUMENT_DIRECTORIES"
877 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
878     occured, the unexpected character and the actually expected, possible
879     character(s), the latter only if less than 5 possibilities)
880 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
881     settings
882 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
883     of strings were treated as being one string containing commas
884     (fixes #57)
885 schoenebeck 1244
886 iliev 959 * Bug fixes:
887     - fixed crash occurring on certain LSCP scripts (Bug 39)
888 persson 1038 - another thread safety fix for lscp "load engine" and "set
889     channel audio output device"
890 iliev 1283 - fixed a crash which occurs when reassigning the same engine
891     on a sampler channel with connected MIDI device
892 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
893     device connected to a sampler channel to number less then or equal
894     to the index of the port to which the sampler channel is connected.
895 iliev 1296 - The previous bindings were not been disconnected when altering
896     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
897     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
898 iliev 1297 - The active stream/voice count statistic was incorrect.
899 iliev 1298 - notification events were not been sent for some sampler
900     channel changes
901 iliev 1305 - added default min and max values to restrict the number of allowed
902     audio output channels and MIDI input ports
903 iliev 1306 - the connection to the PCM interface is now closed when destroying
904     an audio output device
905 schoenebeck 1332 - files with slash in their path or filename could not be loaded
906 iliev 959
907 schoenebeck 1221 * test cases:
908     - updated and fixed (haven't been touched in a while)
909    
910 schoenebeck 937 Version 0.4.0 (24 November 2006)
911 persson 696
912 schoenebeck 697 * packaging changes:
913 capela 868 - changed deprecated copyright attribute to license; added ldconfig
914     to post-(un)install steps; added devel package for liblinuxsampler;
915     to linuxsampler.spec (RPM)
916 schoenebeck 697 - install necessary development header files for allowing 3rd party
917     applications to link against liblinuxsampler
918     - liblinuxsampler's API documentation can be generated with 'make docs'
919     (Doxygen required)
920 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
921     implementation (currently either an integer math solution or a
922     di-harmonic approximation), automatic detection can be overriden
923     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
924     configure script argument though (mandatory for cross-compilation)
925 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
926     provided some on his own (as CXXFLAGS)
927 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
928     messages
929 schoenebeck 852 - added compile time options to allow disabling the various audio and
930     MIDI drivers
931 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
932     (patch by Ebrahim Mayat)
933 schoenebeck 697
934 persson 696 * Gigasampler format engine:
935 schoenebeck 738 - extensive synthesis optimization
936     (reimplementation of EGs and LFO(s), removed synthesis parameter
937     prerendering and the synthesis parameter matrix in general, splitting
938     each audio fragment into subfragments now where each subfragment uses
939 persson 830 constant pitch and filter coefficients. The volume coefficient is
940     linearly interpolated inside a subfragment, unless
941     --disable-interpolate-volume is set.)
942 persson 696 - fine tuning of the EG modulation parameters
943 persson 729 - improved filter cutoff calculation by adding support for the
944     following gig parameters: Cutoff freq (used when no cutoff
945     controller is defined), Control invert, Minimum cutoff, Velocity
946 persson 791 curve and Velocity range. The keyboard tracking now scales
947     cutoff frequency instead of resonance.
948 persson 877 - added support for gig parameter Resonance.
949 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
950 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
951     which can be overridden with --enable-global-attenuation
952 persson 783 - EG fixes: made the length of "attack hold" stage more
953     accurate. Release stage can now start before attack stage
954 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
955     time now has a minimal value to prevent clicks.
956 persson 799 - fixed pitch changes larger than one octave
957 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
958     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
959     all modes can be altered via standard GM messages, that is CC5 for
960     altering portamento time, CC65 for enabling / disabling portamento
961     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
962 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
963     parameter) and crossfade
964 persson 831 - added support for the "attenuation controller threshold" gig
965     parameter
966 persson 832 - added smoothing of volume changes caused by control change
967     messages
968 persson 865 - sample loop parameters are now taken from the DimensionRegion
969     instead of the wave chunk
970     - fixed keyswitching for v3 gigs with a number of keyswitch splits
971     not equal to a power of two
972 persson 877 - reimplementation of the filter algorithm. The new filter is more
973     accurate and supports all gig filter types, including bandreject
974     and lowpass turbo.
975 persson 903 - real support for 24 bit samples - samples are not truncated to
976     16 bits anymore
977     - support for aftertouch (channel pressure, not polyphonic
978     aftertouch)
979 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
980     amplifying from 0)
981 persson 696
982 schoenebeck 711 * LSCP server:
983     - fixed application exit on broken pipe error (fixes bug #20)
984 iliev 793 - fixed the notification messages delay due to lack of
985     network activity (fixes bug #26)
986 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
987     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
988 schoenebeck 711
989 schoenebeck 838 * audio driver:
990     - added aRts audio output driver (by no means RT safe)
991    
992 schoenebeck 775 * MIDI driver:
993     - fixed legacy sysex code which caused dispatching of MIDI SysEx
994     messages several times instead of once
995 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
996     for events (i.e. for offline rendering based MIDI drivers)
997 persson 922 - added checks for bad MIDI data
998 schoenebeck 775
999 schoenebeck 900 * linuxsampler application:
1000     - show available sampler engine types on startup
1001    
1002 schoenebeck 705 * general changes:
1003     - support for muting sampler channels and solo mode of the same, two new
1004     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1005     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1006     introduced for this, the behavior is the same like on a mixer console
1007 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1008     --enable-process-muted-channels which can be used to enable the
1009     processing of muted channels.
1010 iliev 777 - support for sostenuto pedal
1011 iliev 779 - support for monitoring the total number of active voices
1012 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1013     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1014 persson 835 - fixed some memory management errors
1015 persson 841 - fixed some concurrency problems that could lead to crashes when
1016     LSCP commands were executed
1017 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
1018     sampler channel (fixes bug #36)
1019 schoenebeck 705
1020 schoenebeck 692 Version 0.3.3 (15 July 2005)
1021 schoenebeck 686
1022     * packaging changes:
1023     - fixed compilation with gcc 4.0
1024    
1025 schoenebeck 687 * Gigasampler format engine:
1026     - LFO preprocessing was performed even though the respective LFO was
1027     disabled by the instrument patch (minor efficiency fix)
1028 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1029     for volume ramp downs in the same fragment (needed for current voice
1030     stealing implementation) then simply inform the user with a warning
1031     about possible click sounds and reduce the volume ramp down
1032     appropriately instead of cancelling the audio device connection
1033 schoenebeck 687
1034 schoenebeck 677 Version 0.3.2 (24 June 2005)
1035 schoenebeck 609
1036     * packaging changes:
1037     - updated autotools build files to compile on OS X
1038     (conditional compilation of CoreMIDI and MidiShare drivers)
1039 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
1040     './configure --disable-asm' (definitely not recommended)
1041 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
1042     - require automake (>= 1.5) for 'make -f Makefile.cvs'
1043     (due to 'dist-bzip2' automake option)
1044 schoenebeck 649
1045     * Gigasampler format engine:
1046     - support for the gig parameters for "release velocity response" curves
1047     - fine tuning of the EGADSR envelope
1048     - volume of release triggered samples now depends on note-on velocity,
1049     note length and gig parameter "release trigger decay" instead of
1050     note-off velocity.
1051 schoenebeck 663 - revised voice stealing
1052     (fixes crash and endless loop caused by voice stealing)
1053 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
1054 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
1055     instead of when the respective voice is actually launched
1056     (fixes undefined behavior if stolen voices belonged to a key group -
1057     this case was followed by a "killed voice survived" error message)
1058 schoenebeck 669 - fixed minor issue with null/silence samples
1059     (those stole voices even though they don't need a voice at all which
1060     resulted in "voice stealing didn't work out" messages)
1061 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
1062     instrument or audio output device change
1063 schoenebeck 654
1064 schoenebeck 620 * LSCP server:
1065 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1066 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
1067 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
1068 schoenebeck 609
1069 schoenebeck 668 * linuxsampler application:
1070     - added command line parameters --lscp-addr and --lscp-port to override
1071     default IP address and port of LSCP server
1072    
1073 schoenebeck 579 Version 0.3.1 (24 May 2005)
1074    
1075     * initial release
