32 persson 2382
33 persson 2086 * general changes:
34 iliev 2012 - Refactoring: moved the independent code from
35     the Gigasampler format engine to base classes
36 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
37     respective profiling code is currently broken
38 schoenebeck 2053 - Introduced support for optional environment variable
39     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
40     where the sampler shall look for instrument editor plugins
41     (patch by Luis Garrido, slightly modified).
42 schoenebeck 2121 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
43     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
44     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
45     note (in this implementation of the sampler its simply hard routed to
46     the 1st effect send of the sampler channel, no matter what the actual
47     effect type is)
48     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
49     note (in this implementation of the sampler its simply hard routed to
50     the 2nd effect send of the sampler channel, no matter what the actual
51     effect type is)
52 schoenebeck 2124 - implemented support for internal LADSPA effects
53 schoenebeck 2140 - raised limit of program change queue from 100 to 512
54     (as suggested by Alex Stone)
55 iliev 2223 - implemented sine LFO, pulse LFO and saw LFO
56 iliev 2296 - experimental support for per voice equalization
57 iliev 2306 - added command line option --exec-after-init
58 schoenebeck 2330 - Introduced new C++ API method:
59     EngineChannel::InstrumentFileName(int index)
60     allowing to retrieve the whole list of files used for the loaded
61     instrument on an engine channel (a.k.a. part). Some GigaStudio
62     instruments for example are splitted over several files like
63     "Foo.gig", "Foo.gx01", "Foo.gx02", ...
64 schoenebeck 2375 - Added new C++ API method Sampler::GetGlobalMaxVoices().
65     - Added new C++ API method Sampler::GetGlobalMaxStreams().
66     - Added new C++ API method Sampler::SetGlobalMaxVoices().
67     - Added new C++ API method Sampler::SetGlobalMaxStreams().
68 schoenebeck 2377 - Various "const" and "restrict" optimizations.
69 persson 2382 - all engines: add pan CC value to instrument pan parameter before
70     applying panning, instead of using two separate pan functions in
71     series (#182)
72 persson 2427 - added a lock guard class for exception safe mutex handling and
73     used it everywhere appropriate
74 schoenebeck 2448 - Immediately apply scale tuning changes to active voices.
75     - Exposed scale tuning to C++ API (along to the already existing standard
76     SysEx way).
77 persson 2452 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
78     and broken for ppc64. (Seq_cst loads and stores are actually not
79     used in LS, so the bug wasn't noticable.)
80     - lsatomic.h: added ARMv7 support
81 iliev 2012
82 persson 2043 * Gigasampler format engine:
83     - implemented the "round robin keyboard" dimension

87     key
88 persson 2382 - bugfix: pitch LFO controller "internal+aftertouch" was broken
89     - bugfix: filter keyboard tracking was broken
90     - filter performance fix (an unnecessary copy was made of the
91     filter parameters in each sub fragment)
92     - handle special case when pan parameter in gig file has max or
93     min value
94 schoenebeck 2396 - Exclusive Groups: don't ever stop voices of the same note,
95     doesn't sound naturally with a drumkit
96 persson 2408 - fixed EG1 modulation when attack or release is zero

313     - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
314     the driver will automatically connect to other CoreMIDI clients' ports
315     (e.g. external MIDI devices being attached to the Mac)

388     after MIDI/audio device creation failure
389 schoenebeck 2275 - When creating MIDI instrument map entries with "PERSISTENT" type, the
390     instruments were uselessly precached with zero samples, however it still
391     took the full preloading time and on 1st program change the respective
392     instrument was completely reloaded again.
393 persson 2277 - fixed handling of rapid bank select and program change messages
394     sent to the same sampler channel (patch from the Open Octave

417 schoenebeck 1599
418 schoenebeck 1639 * packaging changes:
419     - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

464 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
465     be switched on by command line option "--stacktrace" (the automatic
466     stacktrace mechanism seems to be broken on most systems at the moment)
467 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
468     a pointer to the launched InstrumentEditor object
469 schoenebeck 1876 - added optional 3rd party user data parameter for following

480 schoenebeck 1599 * audio driver:
481     - removed the nonsense audio channel constraint (which was hard coded to
482     max. 100 audio channels) for most audio drivers
483 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
484     opposed to the LSCP specs

490 persson 1748 jack_client_new
491 iliev 1829 - added (experimental) CoreAudio driver
492 persson 1888 - applied old fixes to the ASIO driver that were included in the
493     previous binary release but accidentally never committed to CVS
494     (fixes #117)
495 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
496     win64)
497 persson 1895 - VST: added support for sample rate and buffer size changes
498     - VST: close editor (Fantasia) when the VST is removed

507     AudioChannel::CopyTo() methods using GCC vector exensions
508     (if available)
509 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
510     exception when getting parameters from a disconnected device
511 schoenebeck 1599
512 persson 1651 * MIDI driver:
513     - added JACK MIDI driver
514 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
515     want to (mis)use it for some purpose ("fixed" in all current MIDI
516     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
517 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
518 persson 1887 CoreMidi or AU
519 persson 1889 - fixed mingw-w64 compilation error in MME driver
520 persson 1924 - made program change handling in MIDI thread real-time safe by

531 persson 1908 - work-around for missing fnmatch function on Windows to make
532     instrument database compilable
533 schoenebeck 1930 - added instrument database support on Windows
534     works with both standalone mode and VST plugin.
535     the instruments DB file is located in
536     %USERPROFILE%\.linuxsampler\instruments.db which allows different
537     databases for each windows user
538     if no DB is present it automatically creates the .linuxsampler subdir
539     and then creates an empty DB
540 persson 1943 - fixed recursive import, which was broken on Windows
541 iliev 1603
542 persson 1644 * Gigasampler format engine:
543     - fixed a memory leak that could happen when a channel was deleted

545 persson 1646 - made it possible to load an instrument even if the audio thread
546     isn't running
547 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
548     enough for piano gigs with pedal noise samples
549 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
550     respective FX send MIDI controller was used
551 schoenebeck 1724 - added support for GM global device volume SysEx message
552 schoenebeck 1762 (can be selected at compile time to either apply globally to the
553     whole sampler [default] or only to the sampler channels that are
554     connected to the respective MIDI input port the SysEx message arrived
555     on)
556 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
557     sometimes wrongly killed in the same buffer, causing no sound to
558     be played
559 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
560     which is usally used to switch a part between chromatic sounds and
561     drumkit sounds (as opposed to their common default setting of MIDI
562     part 10 being a drumkit part and all other ones chromatic parts), in
563     LS however one can switch between the first 16 MIDI instrument maps
564     defined for the sampler
565 persson 1764 - made it possible to create multiple sample channels even if the
566     audio thread isn't running
567 persson 1844 - fixed crash when removing channel with active voices (#116)
568 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
569     un-cache the respective sample if it's really not used by any
570     sampler engine anymore
571     - re-cache samples in case they were changed by an instrument editor,
572     e.g. when a sample was added while playing (#82)
573 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
574     same time stamp as the voice's note-on event and occured both in the
575     same audio fragment cycle (fixes bug #112)
576 persson 1858 - added support for the "fine tune" and "pitch bend range"
577     instrument-level gig parameters
578     - fixed minor artifacts in pitch bend handling
579 schoenebeck 1860 - added support for GS Reset SysEx message
580 persson 1862 - allow gig files to use unlimited downward pitch shifting
581     - added a limit check for upward pitch shifting
582 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
583     note was silent
584 persson 1923 - fixed crash happening when a pitch bend event arrived at the
585     same time a new instrument was loading
586 persson 1644
587 schoenebeck 1687 * LSCP server:
588     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
589     react on MIDI data arriving on certain sampler channels (so far only
590     Note-On and Note-Off events are sent via this LSCP event)
591 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
592     react on MIDI data arriving on certain MIDI input devices (so far only
593     Note-On and Note-Off events are sent via this LSCP event)
594 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
595     SET DB_INSTRUMENT FILE_PATH
596 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
597     frontends to send MIDI messages to specific sampler channel
598     - added two additional fields to GET FILE INSTRUMENT INFO command -
599     KEY_BINDINGS and KEYSWITCH_BINDINGS
600 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
601     was incorrect
602 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
603 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
604     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
605     be triggered respectively
606     - added new LSCP command "SET STREAMS" to globally alter the maximum
607     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
608     which will be triggered respectively
609 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
610     a gigedit file dialog is opened)
611 iliev 1848 - close all connections when LSCPServer is deleted
612 iliev 1882 - hard close of all sockets on exit
613 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
614     driver
615 schoenebeck 1687
616 iliev 1761 * Bug fixes:
617     - fixed a crash which occurs when removing a sampler channel waiting

626     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
627     GET MIDI_INPUT_DRIVER INFO
628     GET MIDI_INPUT_DRIVER_PARAMETER INFO

630 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
631 iliev 1847 - fixed crash when changing the audio output device of a sampler
632     channel with loaded instrument and start playing notes
633 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
634 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
635     PowerPC, which probably could cause crashes on that platform
636 persson 1889 - fixed a memory management error which could cause a crash when a
637     plugin was unloaded
638 persson 1896 - bugfix: two private structs had the same name, which could cause

652 persson 1455 * general changes:
653     - bugfix: the thread used by an editor plugin didn't die when the
654     editor closed
655 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
656     out all the space. operator--() did not apply size_mask after
657     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
658     order to avoid problems with the _NonVolatileReader functions.
659     - bugfix: Stream.h: added a missing divide by BytesPerSample in
660     GetWriteSpace(). Since this function is currently only used in
661     the stream's qsort() compare function, it didn't trigger any
662     bugs.
663     - Resampler.h, Synthesizer.h: cubic interpolation now works in
664     24bit mode too. Faster method to read 24bit words on little
665     endian machines (x86): replaced 3 byte reads + shifts with a 1
666     unaligned 32bit read and shift

682     forward slash path separators instead of backslash
683     (i.e. "C:/foo/bar.gig")
684 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
685     apostrophes as well
686 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
687     "LIST FILE INSTRUMENTS <file>" and
688     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
689     about an arbitrary instrument file on the system where the sampler is
690     running on

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