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 iliev 2012
103 persson 2043 * Gigasampler format engine:
104     - implemented the "round robin keyboard" dimension
105     - fixed round robin and random dimensions for cases when number of
106     dimension zones is not a power of two
107     - made round robin use a counter for each region instead of each
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

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

330 persson 2324 - MME: removed compiler warning
331 schoenebeck 2370 - CoreMIDI: implemented driver specific port parameter "CORE_MIDI_BINDINGS",

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

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

582 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
583     enough for piano gigs with pedal noise samples
584 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
585     respective FX send MIDI controller was used
586 schoenebeck 1724 - added support for GM global device volume SysEx message
587 schoenebeck 1762 (can be selected at compile time to either apply globally to the
588     whole sampler [default] or only to the sampler channels that are
589     connected to the respective MIDI input port the SysEx message arrived
590     on)
591 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
592     sometimes wrongly killed in the same buffer, causing no sound to
593     be played
594 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
595     which is usally used to switch a part between chromatic sounds and
596     drumkit sounds (as opposed to their common default setting of MIDI
597     part 10 being a drumkit part and all other ones chromatic parts), in
598     LS however one can switch between the first 16 MIDI instrument maps
599     defined for the sampler
600 persson 1764 - made it possible to create multiple sample channels even if the
601     audio thread isn't running
602 persson 1844 - fixed crash when removing channel with active voices (#116)
603 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
604     un-cache the respective sample if it's really not used by any
605     sampler engine anymore
606     - re-cache samples in case they were changed by an instrument editor,
607     e.g. when a sample was added while playing (#82)
608 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
609     same time stamp as the voice's note-on event and occured both in the
610     same audio fragment cycle (fixes bug #112)
611 persson 1858 - added support for the "fine tune" and "pitch bend range"
612     instrument-level gig parameters
613     - fixed minor artifacts in pitch bend handling

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

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

632     frontends to send MIDI messages to specific sampler channel
633     - added two additional fields to GET FILE INSTRUMENT INFO command -
634     KEY_BINDINGS and KEYSWITCH_BINDINGS
635 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
636     was incorrect
637 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
638 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
639     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
640     be triggered respectively
641     - added new LSCP command "SET STREAMS" to globally alter the maximum
642     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
643     which will be triggered respectively
644 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
645     a gigedit file dialog is opened)
646 iliev 1848 - close all connections when LSCPServer is deleted
647 iliev 1882 - hard close of all sockets on exit

688     - bugfix: the thread used by an editor plugin didn't die when the
689     editor closed
690 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
691     out all the space. operator--() did not apply size_mask after
692     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
693     order to avoid problems with the _NonVolatileReader functions.
694     - bugfix: Stream.h: added a missing divide by BytesPerSample in
695     GetWriteSpace(). Since this function is currently only used in
696     the stream's qsort() compare function, it didn't trigger any
697     bugs.
698     - Resampler.h, Synthesizer.h: cubic interpolation now works in
699     24bit mode too. Faster method to read 24bit words on little
700     endian machines (x86): replaced 3 byte reads + shifts with a 1

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