38 persson 2086 * general changes:
39 iliev 2012 - Refactoring: moved the independent code from
40     the Gigasampler format engine to base classes
41 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
42     respective profiling code is currently broken
43 schoenebeck 2053 - Introduced support for optional environment variable
44     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
45     where the sampler shall look for instrument editor plugins
46     (patch by Luis Garrido, slightly modified).
47 schoenebeck 2121 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
48     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
49     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
50     note (in this implementation of the sampler its simply hard routed to
51     the 1st effect send of the sampler channel, no matter what the actual
52     effect type is)
53     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
54     note (in this implementation of the sampler its simply hard routed to
55     the 2nd effect send of the sampler channel, no matter what the actual
56     effect type is)
57 schoenebeck 2124 - implemented support for internal LADSPA effects
58 schoenebeck 2140 - raised limit of program change queue from 100 to 512
59     (as suggested by Alex Stone)
60 iliev 2223 - implemented sine LFO, pulse LFO and saw LFO
61 iliev 2296 - experimental support for per voice equalization
62 iliev 2306 - added command line option --exec-after-init
63 schoenebeck 2330 - Introduced new C++ API method:
64     EngineChannel::InstrumentFileName(int index)
65     allowing to retrieve the whole list of files used for the loaded
66     instrument on an engine channel (a.k.a. part). Some GigaStudio
67     instruments for example are splitted over several files like
68     "Foo.gig", "Foo.gx01", "Foo.gx02", ...
69 schoenebeck 2375 - Added new C++ API method Sampler::GetGlobalMaxVoices().
70     - Added new C++ API method Sampler::GetGlobalMaxStreams().
71     - Added new C++ API method Sampler::SetGlobalMaxVoices().
72     - Added new C++ API method Sampler::SetGlobalMaxStreams().
73 schoenebeck 2377 - Various "const" and "restrict" optimizations.
74 persson 2382 - all engines: add pan CC value to instrument pan parameter before
75     applying panning, instead of using two separate pan functions in
76     series (#182)
77 persson 2427 - added a lock guard class for exception safe mutex handling and
78     used it everywhere appropriate
79 schoenebeck 2448 - Immediately apply scale tuning changes to active voices.
80     - Exposed scale tuning to C++ API (along to the already existing standard
81     SysEx way).
82 persson 2452 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
83     and broken for ppc64. (Seq_cst loads and stores are actually not
84     used in LS, so the bug wasn't noticable.)
85     - lsatomic.h: added ARMv7 support
86 schoenebeck 2500 - Added support for multiple MIDI input ports per sampler channel (and
87     added various new C++ methods for this new feature / design change, old
88     C++ API methods for managing SamplerChannel's MIDI inputs are now marked
89     as deprecated but are still there and should provide full behavior
90     backward compatibility).
91     - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
92     unsafe and caused compilation error with clang 2.x).
93 schoenebeck 2506 - Bugfix: only process the latest MIDI program change event.
94 iliev 2012
95 persson 2043 * Gigasampler format engine:
96     - implemented the "round robin keyboard" dimension
97     - fixed round robin and random dimensions for cases when number of
98     dimension zones is not a power of two
99     - made round robin use a counter for each region instead of each
100     key
101 persson 2382 - bugfix: pitch LFO controller "internal+aftertouch" was broken
102     - bugfix: filter keyboard tracking was broken
103     - filter performance fix (an unnecessary copy was made of the
104     filter parameters in each sub fragment)
105     - handle special case when pan parameter in gig file has max or
106     min value
107 schoenebeck 2396 - Exclusive Groups: don't ever stop voices of the same note,
108     doesn't sound naturally with a drumkit
109 persson 2408 - fixed EG1 modulation when attack or release is zero
110 persson 2043

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

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

322 persson 2324 - MME: removed compiler warning
323 schoenebeck 2370 - CoreMIDI: implemented driver specific port parameter "CORE_MIDI_BINDINGS",
324     which allows to retrieve the list of CoreMIDI clients / ports and to connect
325     to them a la JACK, via the usual sampler APIs
326     - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
327     the driver will automatically connect to other CoreMIDI clients' ports
328     (e.g. external MIDI devices being attached to the Mac)
329 schoenebeck 2380 - added support for MIDI note on velocity filter
330 persson 2382 - CoreMIDI: fixed memory deallocation error

486     a pointer to the launched InstrumentEditor object
487 schoenebeck 1876 - added optional 3rd party user data parameter for following

529     exception when getting parameters from a disconnected device
530 schoenebeck 1599
531 persson 1651 * MIDI driver:
532     - added JACK MIDI driver
533 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously

551     instrument database compilable
552 schoenebeck 1930 - added instrument database support on Windows
553     works with both standalone mode and VST plugin.
554     the instruments DB file is located in
555     %USERPROFILE%\.linuxsampler\instruments.db which allows different
556     databases for each windows user
557     if no DB is present it automatically creates the .linuxsampler subdir
558     and then creates an empty DB
559 persson 1943 - fixed recursive import, which was broken on Windows
560 iliev 1603
561 persson 1644 * Gigasampler format engine:

566 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
567     enough for piano gigs with pedal noise samples
568 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
569     respective FX send MIDI controller was used
570 schoenebeck 1724 - added support for GM global device volume SysEx message
571 schoenebeck 1762 (can be selected at compile time to either apply globally to the
572     whole sampler [default] or only to the sampler channels that are
573     connected to the respective MIDI input port the SysEx message arrived
574     on)
575 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
576     sometimes wrongly killed in the same buffer, causing no sound to
577     be played
578 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
579     which is usally used to switch a part between chromatic sounds and
580     drumkit sounds (as opposed to their common default setting of MIDI
581     part 10 being a drumkit part and all other ones chromatic parts), in
582     LS however one can switch between the first 16 MIDI instrument maps
583     defined for the sampler
584 persson 1764 - made it possible to create multiple sample channels even if the
585     audio thread isn't running
586 persson 1844 - fixed crash when removing channel with active voices (#116)
587 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
588     un-cache the respective sample if it's really not used by any
589     sampler engine anymore
590     - re-cache samples in case they were changed by an instrument editor,
591     e.g. when a sample was added while playing (#82)
592 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
593     same time stamp as the voice's note-on event and occured both in the
594     same audio fragment cycle (fixes bug #112)
595 persson 1858 - added support for the "fine tune" and "pitch bend range"
596     instrument-level gig parameters
597     - fixed minor artifacts in pitch bend handling
598 schoenebeck 1860 - added support for GS Reset SysEx message
599 persson 1862 - allow gig files to use unlimited downward pitch shifting
600     - added a limit check for upward pitch shifting
601 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
602     note was silent
603 persson 1923 - fixed crash happening when a pitch bend event arrived at the
604     same time a new instrument was loading
605 persson 1644
606 schoenebeck 1687 * LSCP server:

608     react on MIDI data arriving on certain sampler channels (so far only
609     Note-On and Note-Off events are sent via this LSCP event)
610 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
611     react on MIDI data arriving on certain MIDI input devices (so far only
612     Note-On and Note-Off events are sent via this LSCP event)
613 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
614     SET DB_INSTRUMENT FILE_PATH

616     frontends to send MIDI messages to specific sampler channel
617     - added two additional fields to GET FILE INSTRUMENT INFO command -
618     KEY_BINDINGS and KEYSWITCH_BINDINGS
619 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
620     was incorrect
621 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
622 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
623     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
624     be triggered respectively
625     - added new LSCP command "SET STREAMS" to globally alter the maximum
626     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
627     which will be triggered respectively
628 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
629     a gigedit file dialog is opened)
630 iliev 1848 - close all connections when LSCPServer is deleted
631 iliev 1882 - hard close of all sockets on exit

650 iliev 1847 - fixed crash when changing the audio output device of a sampler
651     channel with loaded instrument and start playing notes
652 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
653 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit

672     - bugfix: the thread used by an editor plugin didn't die when the
673     editor closed
674 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
675     out all the space. operator--() did not apply size_mask after
676     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
677     order to avoid problems with the _NonVolatileReader functions.
678     - bugfix: Stream.h: added a missing divide by BytesPerSample in
679     GetWriteSpace(). Since this function is currently only used in
680     the stream's qsort() compare function, it didn't trigger any
681     bugs.
682     - Resampler.h, Synthesizer.h: cubic interpolation now works in
683     24bit mode too. Faster method to read 24bit words on little
684     endian machines (x86): replaced 3 byte reads + shifts with a 1

701     forward slash path separators instead of backslash
702     (i.e. "C:/foo/bar.gig")
703 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
704     apostrophes as well
705 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
706     "LIST FILE INSTRUMENTS <file>" and
707     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
708     about an arbitrary instrument file on the system where the sampler is
709     running on

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