46 persson 2382
47 persson 2086 * general changes:
48 iliev 2012 - Refactoring: moved the independent code from
49     the Gigasampler format engine to base classes
50 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
51     respective profiling code is currently broken
52 schoenebeck 2053 - Introduced support for optional environment variable
53     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
54     where the sampler shall look for instrument editor plugins
55     (patch by Luis Garrido, slightly modified).
56 schoenebeck 2121 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
57     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
58     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
59     note (in this implementation of the sampler its simply hard routed to
60     the 1st effect send of the sampler channel, no matter what the actual
61     effect type is)
62     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
63     note (in this implementation of the sampler its simply hard routed to
64     the 2nd effect send of the sampler channel, no matter what the actual
65     effect type is)
66 schoenebeck 2124 - implemented support for internal LADSPA effects
67 schoenebeck 2140 - raised limit of program change queue from 100 to 512
68     (as suggested by Alex Stone)
69 iliev 2223 - implemented sine LFO, pulse LFO and saw LFO
70 iliev 2296 - experimental support for per voice equalization
71 iliev 2306 - added command line option --exec-after-init
72 schoenebeck 2330 - Introduced new C++ API method:
73     EngineChannel::InstrumentFileName(int index)
74     allowing to retrieve the whole list of files used for the loaded
75     instrument on an engine channel (a.k.a. part). Some GigaStudio
76     instruments for example are splitted over several files like
77     "Foo.gig", "Foo.gx01", "Foo.gx02", ...
78 schoenebeck 2375 - Added new C++ API method Sampler::GetGlobalMaxVoices().
79     - Added new C++ API method Sampler::GetGlobalMaxStreams().
80     - Added new C++ API method Sampler::SetGlobalMaxVoices().
81     - Added new C++ API method Sampler::SetGlobalMaxStreams().
82 schoenebeck 2377 - Various "const" and "restrict" optimizations.
83 persson 2382 - all engines: add pan CC value to instrument pan parameter before
84     applying panning, instead of using two separate pan functions in
85     series (#182)
86 persson 2427 - added a lock guard class for exception safe mutex handling and
87     used it everywhere appropriate
88 schoenebeck 2448 - Immediately apply scale tuning changes to active voices.
89     - Exposed scale tuning to C++ API (along to the already existing standard
90     SysEx way).
91 persson 2452 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
92     and broken for ppc64. (Seq_cst loads and stores are actually not
93     used in LS, so the bug wasn't noticable.)
94     - lsatomic.h: added ARMv7 support
95 schoenebeck 2500 - Added support for multiple MIDI input ports per sampler channel (and
96     added various new C++ methods for this new feature / design change, old
97     C++ API methods for managing SamplerChannel's MIDI inputs are now marked
98     as deprecated but are still there and should provide full behavior
99     backward compatibility).
100     - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
101     unsafe and caused compilation error with clang 2.x).
102 schoenebeck 2506 - Bugfix: only process the latest MIDI program change event.
103 schoenebeck 2515 - Introducing the LSCP shell, which provides convenient control of the
104     sampler from the command line by providing LSCP aware features.
105 schoenebeck 2521 - VirtualMidiDevice: Added support for program change.
106     - VirtualMidiDevice: Added support for bank select (MSB & LSB).
107     - VirtualMidiDevice: Added support for pitch bend.
108 schoenebeck 2559 - Aftertouch: extended API to explicitly handle channel pressure and
109     polyphonic key pressure events (so far polyphonic pressure was not
110     supported at all, and channel pressure was rerouted as CC128 but not
111     used so far).
112 schoenebeck 2594 - Added initial support for real-time instrument scripts. The script VM
113     code is shared by all sampler engine implemementations, however only the
114     gig file format currently provides support for storing instrument scripts
115     (as LinuxSampler extension to the original GigaStudio 4 format).
116 iliev 2012
117 persson 2043 * Gigasampler format engine:
118     - implemented the "round robin keyboard" dimension
119     - fixed round robin and random dimensions for cases when number of
120     dimension zones is not a power of two

126     filter parameters in each sub fragment)
127     - handle special case when pan parameter in gig file has max or
128     min value
129 schoenebeck 2396 - Exclusive Groups: don't ever stop voices of the same note,
130     doesn't sound naturally with a drumkit
131 persson 2408 - fixed EG1 modulation when attack or release is zero
132 schoenebeck 2559 - Fixed support for 'aftertouch' attenuation controller.

317 persson 2165 - save engine type (gig, sfz or sf2) in plugin state
318     - VST: when opening Fantasia, look for both 32 and 64 bit Java on

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

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

538 schoenebeck 2509 - ignore missing LADSPA paths without ignoring valid LADSPA paths
539     (fixes #208)
540 schoenebeck 2523 - Fixed bug in LSCP grammar definition which caused a statement like
541     "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
542     practically irrelevant, however it caused problems with the new LSCP
543     shell's auto completion feature).
544 schoenebeck 2672 - Fixed MIDI program change messages being ignored if quickly executed
545     after each other (fixes #231).

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

623 iliev 1829 - added (experimental) CoreAudio driver
624 persson 1888 - applied old fixes to the ASIO driver that were included in the
625     previous binary release but accidentally never committed to CVS
626     (fixes #117)
627 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
628     win64)

664     instrument database compilable
665 schoenebeck 1930 - added instrument database support on Windows
666     works with both standalone mode and VST plugin.
667     the instruments DB file is located in
668     %USERPROFILE%\.linuxsampler\instruments.db which allows different
669     databases for each windows user
670     if no DB is present it automatically creates the .linuxsampler subdir
671     and then creates an empty DB
672 persson 1943 - fixed recursive import, which was broken on Windows
673 iliev 1603
674 persson 1644 * Gigasampler format engine:
675     - fixed a memory leak that could happen when a channel was deleted

677 persson 1646 - made it possible to load an instrument even if the audio thread
678     isn't running
679 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
680     enough for piano gigs with pedal noise samples
681 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
682     respective FX send MIDI controller was used
683 schoenebeck 1724 - added support for GM global device volume SysEx message
684 schoenebeck 1762 (can be selected at compile time to either apply globally to the
685     whole sampler [default] or only to the sampler channels that are
686     connected to the respective MIDI input port the SysEx message arrived
687     on)
688 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
689     sometimes wrongly killed in the same buffer, causing no sound to
690     be played
691 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
692     which is usally used to switch a part between chromatic sounds and
693     drumkit sounds (as opposed to their common default setting of MIDI
694     part 10 being a drumkit part and all other ones chromatic parts), in
695     LS however one can switch between the first 16 MIDI instrument maps
696     defined for the sampler
697 persson 1764 - made it possible to create multiple sample channels even if the
698     audio thread isn't running

701     un-cache the respective sample if it's really not used by any
702     sampler engine anymore
703     - re-cache samples in case they were changed by an instrument editor,
704     e.g. when a sample was added while playing (#82)
705 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
706     same time stamp as the voice's note-on event and occured both in the
707     same audio fragment cycle (fixes bug #112)
708 persson 1858 - added support for the "fine tune" and "pitch bend range"
709     instrument-level gig parameters
710     - fixed minor artifacts in pitch bend handling

714 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
715     note was silent
716 persson 1923 - fixed crash happening when a pitch bend event arrived at the
717     same time a new instrument was loading
718 persson 1644
719 schoenebeck 1687 * LSCP server:
720     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
721     react on MIDI data arriving on certain sampler channels (so far only
722     Note-On and Note-Off events are sent via this LSCP event)
723 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
724     react on MIDI data arriving on certain MIDI input devices (so far only
725     Note-On and Note-Off events are sent via this LSCP event)
726 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
727     SET DB_INSTRUMENT FILE_PATH
728 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
729     frontends to send MIDI messages to specific sampler channel
730     - added two additional fields to GET FILE INSTRUMENT INFO command -
731     KEY_BINDINGS and KEYSWITCH_BINDINGS
732 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
733     was incorrect
734 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
735 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
736     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
737     be triggered respectively
738     - added new LSCP command "SET STREAMS" to globally alter the maximum
739     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
740     which will be triggered respectively
741 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
742     a gigedit file dialog is opened)
743 iliev 1848 - close all connections when LSCPServer is deleted
744 iliev 1882 - hard close of all sockets on exit
745 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
746     driver
747 schoenebeck 1687
748 iliev 1761 * Bug fixes:
749     - fixed a crash which occurs when removing a sampler channel waiting
750     to start instrument loading after another channel
751 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
752     instrument loading in progress (bug #113)
753 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
754     instrument with PERSISTENT load mode
755 iliev 1835 - fixed possible iterator invalidations when resetting the sampler

762 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
763 iliev 1847 - fixed crash when changing the audio output device of a sampler
764     channel with loaded instrument and start playing notes
765 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
766 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
767     PowerPC, which probably could cause crashes on that platform
768 persson 1889 - fixed a memory management error which could cause a crash when a
769     plugin was unloaded
770 persson 1896 - bugfix: two private structs had the same name, which could cause
771     problems if the linker chose the wrong constructor
772 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
773     Windows

775    
776 schoenebeck 1560 Version 0.5.1 (6 December 2007)
777 schoenebeck 1454
778     * packaging changes:
779     - added autoconf checks for pthread library
780     - added autoconf check for pthread bug found on certain NPTL-enabled
781     glibc versions (see Gentoo bug report #194076)
782 senoner 1502 - added autoconf checks for MS Windows
783 schoenebeck 1454
784 persson 1455 * general changes:
785     - bugfix: the thread used by an editor plugin didn't die when the
786     editor closed
787 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
788     out all the space. operator--() did not apply size_mask after
789     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
790     order to avoid problems with the _NonVolatileReader functions.
791     - bugfix: Stream.h: added a missing divide by BytesPerSample in
792     GetWriteSpace(). Since this function is currently only used in
793     the stream's qsort() compare function, it didn't trigger any
794     bugs.
795     - Resampler.h, Synthesizer.h: cubic interpolation now works in
796     24bit mode too. Faster method to read 24bit words on little
797     endian machines (x86): replaced 3 byte reads + shifts with a 1
798     unaligned 32bit read and shift
799     - experimental support for MS Windows (MIDI input via MME, AUDIO
800     output via ASIO)
801     - made handling of SIGINT signal (Ctrl-C) a bit more robust
802 iliev 1541 - support for monitoring the total number of active disk streams
803     (new LSCP commands: GET TOTAL_STREAM_COUNT,
804     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
805 persson 1455
806 senoner 1500 * AUDIO driver:
807 persson 1534 - added Windows ASIO low latency audio driver
808 senoner 1500
809 senoner 1485 * MIDI driver:
810 schoenebeck 1495 - added MME Windows MIDI driver
811 senoner 1485
812 schoenebeck 1471 * LSCP server:
813     - added support for Windows style path / filenames, however with
814     forward slash path separators instead of backslash
815     (i.e. "C:/foo/bar.gig")
816 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
817     apostrophes as well
818 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
819     "LIST FILE INSTRUMENTS <file>" and
820     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
821     about an arbitrary instrument file on the system where the sampler is
822     running on
823 schoenebeck 1471
824 schoenebeck 1424 Version 0.5.0 (15 October 2007)
825 schoenebeck 947
826 schoenebeck 1065 * packaging changes:
827 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
828     API header files anymore
829 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
830     the Doxygen API documentation (explicitly listed in Doxyfile.in)
831 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
832     capable to execute our autoconf environment, thus no need anymore
833     to maintain the compile time configuration file (osx/version.h) for
834     OSX manually (patch by Toshi Nagata)
835 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
836     parameters
837 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
838     C++ API header files, all implementation internal global definitions
839     are now in global_private.h
840     - atomic.h is not exposed to the C++ API anymore
841     - no need to include config.h anymore for using LS's API header files
842     - fixed warnings in API doc generation
843 schoenebeck 1065
844 schoenebeck 947 * general changes:
845     - replaced the old, confusing MIDI program change mechanism by a
846     flexible MIDI instrument mapper which allows to map arbitrary
847 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
848 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
849     loaded on the respective channel when such MIDI program change
850     messages arrive, beside that, each entry allows to define a life-time
851     strategy for the instrument, so the user can define whether the
852     instrument should i.e. be permanently loaded (to be able to switch
853     quickly among sounds) or i.e. loaded just on demand when the
854     respective program change arrives (to safe RAM space), as well as a
855     global volume factor for each entry, so the user can adjust the volume
856     dynamic of his mapped instrument collection without having to modify
857 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
858     MIDI instrument maps and assign each sampler channel individually
859     a certain map, so that i.e. separation of normal instruments and
860     drumkits is possible
861 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
862     MIDI instrument maps, MIDI instruments, FX sends, global volume.
863 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
864     due to a constant size RingBuffer FIFO which is now replaced by a
865     dynamic (unlimited) size std::list FIFO
866 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
867     output channels for being processed by external effect processors
868     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
869     controllers
870 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
871 iliev 1130 - Implemented new, improved notification system
872 schoenebeck 1149 - fixed compilation errors regarding OSX
873     (patch by Toshi Nagata)
874 iliev 1161 - implemented instruments database
875 iliev 1345 - added support for escape sequences to the instruments database
876 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
877     within the sampler's process (by using instrument editor plugins),
878     you'll notice the new "Registered instrument editors:" message on
879 schoenebeck 1407 startup, added a new LSCP command:
880     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
881 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
882     given sampler channel, the plugin path can be overridden at compile
883     time with ./configure --enable-plugin-dir=/some/dir
884 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
885     in the sampler's process to safely edit instruments while playing
886     without a crash (hopefully) by either suspending single regions
887     wherever possible or if unavoidable whole engine(s)
888 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
889     policy and priority on thread level, set a minimum stack size for
890     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
891     threads simply inherited properties of starting thread instead of
892     setting their own policy and priority
893 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
894     main process did not wait for the stack trace process to finish
895     its output
896 persson 1248 - fixed some minor memory leaks
897 schoenebeck 1259 - reenabled assembly features support, at the moment only for
898     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
899 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
900     register, to avoid relocations in the text segment at runtime)
901 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
902 schoenebeck 947
903     * MIDI driver:
904     - dispatch bank select (MSB and LSB) messages
905    
906 schoenebeck 1049 * audio driver:
907     - the ALSA audio output driver parameters now reflect the correct
908     parameter value ranges for the respective selected sound card
909     (patch by Till Wimmer, a bit fixed and extended)
910    
911 persson 951 * Gigasampler format engine:
912     - if a filter is used and EG2 finishes before EG1, let the voice
913     die when EG2 has finished (this fixes a problem with clicks and
914     voice starvation for some gigs)
915 persson 1038 - playback is no longer disabled during instrument loading
916     - all notes playing on a channel that changes its instrument keep
917     playing with the old instrument until they get a note off
918     command
919 persson 1039 - EG fix: a release value of zero could cause noises or crash
920 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
921 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
922     above max sustain level, which means that there is a decay phase
923     even if sustain is 100%
924 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
925     noises or crashes
926 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
927 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
928     supplied to the configure script (fixes #46)
929 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
930     instead of a fix value
931 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
932     127 (solo mode) only kill voices if the respective mode really
933     changed
934 persson 951
935 schoenebeck 1244 * LSCP server:
936     - fixed compile time error for old Bison versions
937     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
938 schoenebeck 1245 - parser now supports extended ASCII character set
939     (up to ASCII code 255, i.e. includes now umlauts and accents)
940     - filename arguments in LSCP commands now allow to use escape
941     sequences, that is directly literal as one of: \', \", \\, \n, \r,
942     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
943     code value like \xf2) (fixes bug #24)
944 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
945     least one of their text-based parameters (i.e. name, description):
946     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
947     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
948     "SET DB_INSTRUMENT_DIRECTORY NAME",
949     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
950     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
951     "FIND DB_INSTRUMENT_DIRECTORIES"
952 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
953     occured, the unexpected character and the actually expected, possible
954     character(s), the latter only if less than 5 possibilities)
955 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
956     settings
957 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
958     of strings were treated as being one string containing commas
959     (fixes #57)
960 schoenebeck 1244
961 iliev 959 * Bug fixes:
962     - fixed crash occurring on certain LSCP scripts (Bug 39)
963 persson 1038 - another thread safety fix for lscp "load engine" and "set
964     channel audio output device"
965 iliev 1283 - fixed a crash which occurs when reassigning the same engine
966     on a sampler channel with connected MIDI device
967 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
968     device connected to a sampler channel to number less then or equal
969     to the index of the port to which the sampler channel is connected.
970 iliev 1296 - The previous bindings were not been disconnected when altering
971     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
972     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
973 iliev 1297 - The active stream/voice count statistic was incorrect.
974 iliev 1298 - notification events were not been sent for some sampler
975     channel changes
976 iliev 1305 - added default min and max values to restrict the number of allowed
977     audio output channels and MIDI input ports
978 iliev 1306 - the connection to the PCM interface is now closed when destroying
979     an audio output device
980 schoenebeck 1332 - files with slash in their path or filename could not be loaded
981 iliev 959
982 schoenebeck 1221 * test cases:
983     - updated and fixed (haven't been touched in a while)
984    
985 schoenebeck 937 Version 0.4.0 (24 November 2006)
986 persson 696
987 schoenebeck 697 * packaging changes:
988 capela 868 - changed deprecated copyright attribute to license; added ldconfig
989     to post-(un)install steps; added devel package for liblinuxsampler;
990     to linuxsampler.spec (RPM)
991 schoenebeck 697 - install necessary development header files for allowing 3rd party
992     applications to link against liblinuxsampler
993     - liblinuxsampler's API documentation can be generated with 'make docs'
994     (Doxygen required)
995 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
996     implementation (currently either an integer math solution or a
997     di-harmonic approximation), automatic detection can be overriden
998     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
999     configure script argument though (mandatory for cross-compilation)
1000 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
1001     provided some on his own (as CXXFLAGS)
1002 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
1003     messages
1004 schoenebeck 852 - added compile time options to allow disabling the various audio and
1005     MIDI drivers
1006 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
1007     (patch by Ebrahim Mayat)
1008 schoenebeck 697
1009 persson 696 * Gigasampler format engine:
1010 schoenebeck 738 - extensive synthesis optimization
1011     (reimplementation of EGs and LFO(s), removed synthesis parameter
1012     prerendering and the synthesis parameter matrix in general, splitting
1013     each audio fragment into subfragments now where each subfragment uses
1014 persson 830 constant pitch and filter coefficients. The volume coefficient is
1015     linearly interpolated inside a subfragment, unless
1016     --disable-interpolate-volume is set.)
1017 persson 696 - fine tuning of the EG modulation parameters
1018 persson 729 - improved filter cutoff calculation by adding support for the
1019     following gig parameters: Cutoff freq (used when no cutoff
1020     controller is defined), Control invert, Minimum cutoff, Velocity
1021 persson 791 curve and Velocity range. The keyboard tracking now scales
1022     cutoff frequency instead of resonance.
1023 persson 877 - added support for gig parameter Resonance.
1024 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
1025 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1026     which can be overridden with --enable-global-attenuation
1027 persson 783 - EG fixes: made the length of "attack hold" stage more
1028     accurate. Release stage can now start before attack stage
1029 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
1030     time now has a minimal value to prevent clicks.
1031 persson 799 - fixed pitch changes larger than one octave
1032 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1033     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1034     all modes can be altered via standard GM messages, that is CC5 for
1035     altering portamento time, CC65 for enabling / disabling portamento
1036     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1037 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1038     parameter) and crossfade
1039 persson 831 - added support for the "attenuation controller threshold" gig
1040     parameter
1041 persson 832 - added smoothing of volume changes caused by control change
1042     messages
1043 persson 865 - sample loop parameters are now taken from the DimensionRegion
1044     instead of the wave chunk
1045     - fixed keyswitching for v3 gigs with a number of keyswitch splits
1046     not equal to a power of two
1047 persson 877 - reimplementation of the filter algorithm. The new filter is more
1048     accurate and supports all gig filter types, including bandreject
1049     and lowpass turbo.
1050 persson 903 - real support for 24 bit samples - samples are not truncated to
1051     16 bits anymore
1052     - support for aftertouch (channel pressure, not polyphonic
1053     aftertouch)
1054 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
1055     amplifying from 0)
1056 persson 696
1057 schoenebeck 711 * LSCP server:
1058     - fixed application exit on broken pipe error (fixes bug #20)
1059 iliev 793 - fixed the notification messages delay due to lack of
1060     network activity (fixes bug #26)
1061 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
1062     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1063 schoenebeck 711
1064 schoenebeck 838 * audio driver:
1065     - added aRts audio output driver (by no means RT safe)
1066    
1067 schoenebeck 775 * MIDI driver:
1068     - fixed legacy sysex code which caused dispatching of MIDI SysEx
1069     messages several times instead of once
1070 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
1071     for events (i.e. for offline rendering based MIDI drivers)
1072 persson 922 - added checks for bad MIDI data
1073 schoenebeck 775
1074 schoenebeck 900 * linuxsampler application:
1075     - show available sampler engine types on startup
1076    
1077 schoenebeck 705 * general changes:
1078     - support for muting sampler channels and solo mode of the same, two new
1079     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1080     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1081     introduced for this, the behavior is the same like on a mixer console
1082 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1083     --enable-process-muted-channels which can be used to enable the
1084     processing of muted channels.
1085 iliev 777 - support for sostenuto pedal
1086 iliev 779 - support for monitoring the total number of active voices
1087 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1088     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1089 persson 835 - fixed some memory management errors
1090 persson 841 - fixed some concurrency problems that could lead to crashes when
1091     LSCP commands were executed
1092 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
1093     sampler channel (fixes bug #36)
1094 schoenebeck 705
1095 schoenebeck 692 Version 0.3.3 (15 July 2005)
1096 schoenebeck 686
1097     * packaging changes:
1098     - fixed compilation with gcc 4.0
1099    
1100 schoenebeck 687 * Gigasampler format engine:
1101     - LFO preprocessing was performed even though the respective LFO was
1102     disabled by the instrument patch (minor efficiency fix)
1103 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1104     for volume ramp downs in the same fragment (needed for current voice
1105     stealing implementation) then simply inform the user with a warning
1106     about possible click sounds and reduce the volume ramp down
1107     appropriately instead of cancelling the audio device connection
1108 schoenebeck 687
1109 schoenebeck 677 Version 0.3.2 (24 June 2005)
1110 schoenebeck 609
1111     * packaging changes:
1112     - updated autotools build files to compile on OS X
1113     (conditional compilation of CoreMIDI and MidiShare drivers)
1114 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
1115     './configure --disable-asm' (definitely not recommended)
1116 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
1117     - require automake (>= 1.5) for 'make -f Makefile.cvs'
1118     (due to 'dist-bzip2' automake option)
1119 schoenebeck 649
1120     * Gigasampler format engine:
1121     - support for the gig parameters for "release velocity response" curves
1122     - fine tuning of the EGADSR envelope
1123     - volume of release triggered samples now depends on note-on velocity,
1124     note length and gig parameter "release trigger decay" instead of
1125     note-off velocity.
1126 schoenebeck 663 - revised voice stealing
1127     (fixes crash and endless loop caused by voice stealing)
1128 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
1129 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
1130     instead of when the respective voice is actually launched
1131     (fixes undefined behavior if stolen voices belonged to a key group -
1132     this case was followed by a "killed voice survived" error message)
1133 schoenebeck 669 - fixed minor issue with null/silence samples
1134     (those stole voices even though they don't need a voice at all which
1135     resulted in "voice stealing didn't work out" messages)
1136 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
1137     instrument or audio output device change
1138 schoenebeck 654
1139 schoenebeck 620 * LSCP server:
1140 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1141 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
1142 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
1143 schoenebeck 609
1144 schoenebeck 668 * linuxsampler application:
1145     - added command line parameters --lscp-addr and --lscp-port to override
1146     default IP address and port of LSCP server
1147    
1148 schoenebeck 579 Version 0.3.1 (24 May 2005)
1149    
1150     * initial release
