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 iliev 2012
100 persson 2043 * Gigasampler format engine:
101     - implemented the "round robin keyboard" dimension

103     dimension zones is not a power of two
104     - made round robin use a counter for each region instead of each
105     key
106 persson 2382 - bugfix: pitch LFO controller "internal+aftertouch" was broken
107     - bugfix: filter keyboard tracking was broken
108     - filter performance fix (an unnecessary copy was made of the
109     filter parameters in each sub fragment)
110     - handle special case when pan parameter in gig file has max or
111     min value
112 schoenebeck 2396 - Exclusive Groups: don't ever stop voices of the same note,
113     doesn't sound naturally with a drumkit

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

323     the ALSA sequencer client name
324 schoenebeck 2140 - removed limit of maximum amount of MIDI ports per MIDI device, since
325     there is no reason for this limit
326 persson 2311 - MME: fixed memory handling bug found with cppcheck
327 persson 2324 - MME: removed compiler warning
328 schoenebeck 2370 - CoreMIDI: implemented driver specific port parameter "CORE_MIDI_BINDINGS",
329     which allows to retrieve the list of CoreMIDI clients / ports and to connect
330     to them a la JACK, via the usual sampler APIs

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

564     instrument database compilable
565 schoenebeck 1930 - added instrument database support on Windows
566     works with both standalone mode and VST plugin.
567     the instruments DB file is located in
568     %USERPROFILE%\.linuxsampler\instruments.db which allows different
569     databases for each windows user
570     if no DB is present it automatically creates the .linuxsampler subdir
571     and then creates an empty DB
572 persson 1943 - fixed recursive import, which was broken on Windows
573 iliev 1603
574 persson 1644 * Gigasampler format engine:

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

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

608 persson 1858 - added support for the "fine tune" and "pitch bend range"
609     instrument-level gig parameters
610     - fixed minor artifacts in pitch bend handling

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

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

629     frontends to send MIDI messages to specific sampler channel
630     - added two additional fields to GET FILE INSTRUMENT INFO command -
631     KEY_BINDINGS and KEYSWITCH_BINDINGS
632 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
633     was incorrect
634 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
635 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
636     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
637     be triggered respectively
638     - added new LSCP command "SET STREAMS" to globally alter the maximum
639     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
640     which will be triggered respectively
641 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
642     a gigedit file dialog is opened)
643 iliev 1848 - close all connections when LSCPServer is deleted

685     - bugfix: the thread used by an editor plugin didn't die when the
686     editor closed
687 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
688     out all the space. operator--() did not apply size_mask after
689     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
690     order to avoid problems with the _NonVolatileReader functions.
691     - bugfix: Stream.h: added a missing divide by BytesPerSample in
692     GetWriteSpace(). Since this function is currently only used in
693     the stream's qsort() compare function, it didn't trigger any
694     bugs.
695     - Resampler.h, Synthesizer.h: cubic interpolation now works in
696     24bit mode too. Faster method to read 24bit words on little
697     endian machines (x86): replaced 3 byte reads + shifts with a 1

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