* LSCP shell (WIP): Added initial support for built-in LSCP reference
  documentation, which will automatically show the relevant LSCP reference
  section on screen as soon as one specific LSCP command was detected while
  typing on the command line.
* Bumped version (1.0.0.svn37).

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.

108     key
109 persson 2382 - bugfix: pitch LFO controller "internal+aftertouch" was broken
110     - bugfix: filter keyboard tracking was broken
111     - filter performance fix (an unnecessary copy was made of the
112     filter parameters in each sub fragment)
113     - handle special case when pan parameter in gig file has max or
114     min value
115 schoenebeck 2396 - Exclusive Groups: don't ever stop voices of the same note,
116     doesn't sound naturally with a drumkit

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

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

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

518 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
519     a pointer to the launched InstrumentEditor object
520 schoenebeck 1876 - added optional 3rd party user data parameter for following

584     instrument database compilable
585 schoenebeck 1930 - added instrument database support on Windows
586     works with both standalone mode and VST plugin.
587     the instruments DB file is located in
588     %USERPROFILE%\.linuxsampler\instruments.db which allows different

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

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

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

628 persson 1858 - added support for the "fine tune" and "pitch bend range"
629     instrument-level gig parameters
630     - fixed minor artifacts in pitch bend handling

632 persson 1862 - allow gig files to use unlimited downward pitch shifting
633     - added a limit check for upward pitch shifting
634 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
635     note was silent
636 persson 1923 - fixed crash happening when a pitch bend event arrived at the
637     same time a new instrument was loading
638 persson 1644
639 schoenebeck 1687 * LSCP server:

651     KEY_BINDINGS and KEYSWITCH_BINDINGS
652 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
653     was incorrect
654 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
655 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
656     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
657     be triggered respectively
658     - added new LSCP command "SET STREAMS" to globally alter the maximum
659     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
660     which will be triggered respectively
661 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
662     a gigedit file dialog is opened)

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