27 persson 2382
28 persson 2086 * general changes:
29 iliev 2012 - Refactoring: moved the independent code from
30     the Gigasampler format engine to base classes
31 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
32     respective profiling code is currently broken
33 schoenebeck 2053 - Introduced support for optional environment variable
34     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
35     where the sampler shall look for instrument editor plugins
36     (patch by Luis Garrido, slightly modified).
37 schoenebeck 2121 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
38     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
39     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
40     note (in this implementation of the sampler its simply hard routed to
41     the 1st effect send of the sampler channel, no matter what the actual
42     effect type is)
43     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
44     note (in this implementation of the sampler its simply hard routed to
45     the 2nd effect send of the sampler channel, no matter what the actual
46     effect type is)
47 schoenebeck 2124 - implemented support for internal LADSPA effects
48 schoenebeck 2140 - raised limit of program change queue from 100 to 512

56     instrument on an engine channel (a.k.a. part). Some GigaStudio
57     instruments for example are splitted over several files like

68     used it everywhere appropriate
69 schoenebeck 2448 - Immediately apply scale tuning changes to active voices.

84     min value
85 schoenebeck 2396 - Exclusive Groups: don't ever stop voices of the same note,

376 iliev 2201 - Fixed possible crashes due to corrupted MIDI/audio device list
377     after MIDI/audio device creation failure
378 schoenebeck 2275 - When creating MIDI instrument map entries with "PERSISTENT" type, the
379     instruments were uselessly precached with zero samples, however it still
380     took the full preloading time and on 1st program change the respective
381     instrument was completely reloaded again.
382 persson 2277 - fixed handling of rapid bank select and program change messages
383     sent to the same sampler channel (patch from the Open Octave

406 schoenebeck 1599
407 schoenebeck 1639 * packaging changes:
408     - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

440 schoenebeck 1653 - be verbose on DLL load errors (on Linux)
441 schoenebeck 1681 - fixed di-harmonic triangle LFO implementation (this LFO implementation

452 persson 1825 - fixed CPU feature detection on x86_64 (maybe fixes #108)
453 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
454     be switched on by command line option "--stacktrace" (the automatic
455     stacktrace mechanism seems to be broken on most systems at the moment)
456 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
457     a pointer to the launched InstrumentEditor object
458 schoenebeck 1876 - added optional 3rd party user data parameter for following

469 schoenebeck 1599 * audio driver:
470     - removed the nonsense audio channel constraint (which was hard coded to
471     max. 100 audio channels) for most audio drivers
472 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
473     opposed to the LSCP specs
474 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
475     reflected the wrong value
476 persson 1644 - fixed a memory management bug in ASIO driver
477 persson 1748 - Makefile fix: JACK_CFLAGS wasn't used

479 persson 1748 jack_client_new
480 iliev 1829 - added (experimental) CoreAudio driver
481 persson 1888 - applied old fixes to the ASIO driver that were included in the
482     previous binary release but accidentally never committed to CVS
483     (fixes #117)
484 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
485     win64)
486 persson 1895 - VST: added support for sample rate and buffer size changes
487     - VST: close editor (Fantasia) when the VST is removed

494     stored in the plugin state
495 schoenebeck 1930 - performance optimization of AudioChannel::MixTo() and
496     AudioChannel::CopyTo() methods using GCC vector exensions
497     (if available)
498 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
499     exception when getting parameters from a disconnected device
500 schoenebeck 1599
501 persson 1651 * MIDI driver:
502     - added JACK MIDI driver
503 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
504     want to (mis)use it for some purpose ("fixed" in all current MIDI
505     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
506 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
507 persson 1887 CoreMidi or AU
508 persson 1889 - fixed mingw-w64 compilation error in MME driver
509 persson 1924 - made program change handling in MIDI thread real-time safe by

515     to the instruments database
516 iliev 1727 - added support for handling lost files in the instruments database
517 iliev 1781 - Implemented option for adding instruments in separate directories
518     in the instruments database
519     (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
520 persson 1908 - work-around for missing fnmatch function on Windows to make
521     instrument database compilable
522 schoenebeck 1930 - added instrument database support on Windows
523     works with both standalone mode and VST plugin.
524     the instruments DB file is located in
525     %USERPROFILE%\.linuxsampler\instruments.db which allows different
526     databases for each windows user
527     if no DB is present it automatically creates the .linuxsampler subdir
528     and then creates an empty DB
529 persson 1943 - fixed recursive import, which was broken on Windows
530 iliev 1603
531 persson 1644 * Gigasampler format engine:
532     - fixed a memory leak that could happen when a channel was deleted

534 persson 1646 - made it possible to load an instrument even if the audio thread
535     isn't running
536 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
537     enough for piano gigs with pedal noise samples
538 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
539     respective FX send MIDI controller was used
540 schoenebeck 1724 - added support for GM global device volume SysEx message
541 schoenebeck 1762 (can be selected at compile time to either apply globally to the
542     whole sampler [default] or only to the sampler channels that are
543     connected to the respective MIDI input port the SysEx message arrived
544     on)
545 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
546     sometimes wrongly killed in the same buffer, causing no sound to
547     be played
548 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
549     which is usally used to switch a part between chromatic sounds and
550     drumkit sounds (as opposed to their common default setting of MIDI
551     part 10 being a drumkit part and all other ones chromatic parts), in
552     LS however one can switch between the first 16 MIDI instrument maps
553     defined for the sampler
554 persson 1764 - made it possible to create multiple sample channels even if the
555     audio thread isn't running
556 persson 1844 - fixed crash when removing channel with active voices (#116)
557 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
558     un-cache the respective sample if it's really not used by any
559     sampler engine anymore
560     - re-cache samples in case they were changed by an instrument editor,
561     e.g. when a sample was added while playing (#82)
562 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
563     same time stamp as the voice's note-on event and occured both in the
564     same audio fragment cycle (fixes bug #112)
565 persson 1858 - added support for the "fine tune" and "pitch bend range"
566     instrument-level gig parameters
567     - fixed minor artifacts in pitch bend handling
568 schoenebeck 1860 - added support for GS Reset SysEx message
569 persson 1862 - allow gig files to use unlimited downward pitch shifting
570     - added a limit check for upward pitch shifting
571 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
572     note was silent
573 persson 1923 - fixed crash happening when a pitch bend event arrived at the
574     same time a new instrument was loading
575 persson 1644
576 schoenebeck 1687 * LSCP server:
577     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
578     react on MIDI data arriving on certain sampler channels (so far only
579     Note-On and Note-Off events are sent via this LSCP event)
580 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
581     react on MIDI data arriving on certain MIDI input devices (so far only
582     Note-On and Note-Off events are sent via this LSCP event)
583 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
584     SET DB_INSTRUMENT FILE_PATH
585 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
586     frontends to send MIDI messages to specific sampler channel
587     - added two additional fields to GET FILE INSTRUMENT INFO command -
588     KEY_BINDINGS and KEYSWITCH_BINDINGS
589 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
590     was incorrect
591 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
592 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
593     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
594     be triggered respectively
595     - added new LSCP command "SET STREAMS" to globally alter the maximum
596     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
597     which will be triggered respectively
598 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
599     a gigedit file dialog is opened)
600 iliev 1848 - close all connections when LSCPServer is deleted
601 iliev 1882 - hard close of all sockets on exit
602 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
603     driver
604 schoenebeck 1687
605 iliev 1761 * Bug fixes:
606     - fixed a crash which occurs when removing a sampler channel waiting
607     to start instrument loading after another channel
608 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
609     instrument loading in progress (bug #113)
610 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
611     instrument with PERSISTENT load mode
612 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
613     - fixed memory leaks when issuing the following LSCP commands:
614     GET AUDIO_OUTPUT_DRIVER INFO
615     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
616     GET MIDI_INPUT_DRIVER INFO
617     GET MIDI_INPUT_DRIVER_PARAMETER INFO
618     - fixed possible compilation error when sqlite is not present
619 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
620 iliev 1847 - fixed crash when changing the audio output device of a sampler
621     channel with loaded instrument and start playing notes
622 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
623 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
624     PowerPC, which probably could cause crashes on that platform
625 persson 1889 - fixed a memory management error which could cause a crash when a
626     plugin was unloaded
627 persson 1896 - bugfix: two private structs had the same name, which could cause
628     problems if the linker chose the wrong constructor
629 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
630     Windows
631 iliev 1761

633 schoenebeck 1560 Version 0.5.1 (6 December 2007)
634 schoenebeck 1454
635     * packaging changes:
636     - added autoconf checks for pthread library
637     - added autoconf check for pthread bug found on certain NPTL-enabled
638     glibc versions (see Gentoo bug report #194076)
639 senoner 1502 - added autoconf checks for MS Windows
640 schoenebeck 1454
641 persson 1455 * general changes:
642     - bugfix: the thread used by an editor plugin didn't die when the
643     editor closed
644 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
645     out all the space. operator--() did not apply size_mask after
646     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
647     order to avoid problems with the _NonVolatileReader functions.
648     - bugfix: Stream.h: added a missing divide by BytesPerSample in
649     GetWriteSpace(). Since this function is currently only used in
650     the stream's qsort() compare function, it didn't trigger any
651     bugs.
652     - Resampler.h, Synthesizer.h: cubic interpolation now works in
653     24bit mode too. Faster method to read 24bit words on little
654     endian machines (x86): replaced 3 byte reads + shifts with a 1
655     unaligned 32bit read and shift
656     - experimental support for MS Windows (MIDI input via MME, AUDIO
657     output via ASIO)
658     - made handling of SIGINT signal (Ctrl-C) a bit more robust
659 iliev 1541 - support for monitoring the total number of active disk streams
660     (new LSCP commands: GET TOTAL_STREAM_COUNT,
661     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
662 persson 1455
663 senoner 1500 * AUDIO driver:
664 persson 1534 - added Windows ASIO low latency audio driver
665 senoner 1500
666 senoner 1485 * MIDI driver:
667 schoenebeck 1495 - added MME Windows MIDI driver
668 senoner 1485
669 schoenebeck 1471 * LSCP server:
670     - added support for Windows style path / filenames, however with
671     forward slash path separators instead of backslash
672     (i.e. "C:/foo/bar.gig")
673 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
674     apostrophes as well
675 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
676     "LIST FILE INSTRUMENTS <file>" and
677     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
678     about an arbitrary instrument file on the system where the sampler is
679     running on
680 schoenebeck 1471
681 schoenebeck 1424 Version 0.5.0 (15 October 2007)
682 schoenebeck 947
683 schoenebeck 1065 * packaging changes:
684 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
685     API header files anymore
686 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
687     the Doxygen API documentation (explicitly listed in Doxyfile.in)
688 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
689     capable to execute our autoconf environment, thus no need anymore
690     to maintain the compile time configuration file (osx/version.h) for
691     OSX manually (patch by Toshi Nagata)
692 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
693     parameters
694 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
695     C++ API header files, all implementation internal global definitions
696     are now in global_private.h
697     - atomic.h is not exposed to the C++ API anymore
698     - no need to include config.h anymore for using LS's API header files
699     - fixed warnings in API doc generation
700 schoenebeck 1065
701 schoenebeck 947 * general changes:
702     - replaced the old, confusing MIDI program change mechanism by a
703     flexible MIDI instrument mapper which allows to map arbitrary
704 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
705 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
706     loaded on the respective channel when such MIDI program change
707     messages arrive, beside that, each entry allows to define a life-time
708     strategy for the instrument, so the user can define whether the
709     instrument should i.e. be permanently loaded (to be able to switch
710     quickly among sounds) or i.e. loaded just on demand when the
711     respective program change arrives (to safe RAM space), as well as a
712     global volume factor for each entry, so the user can adjust the volume
713     dynamic of his mapped instrument collection without having to modify
714 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
715     MIDI instrument maps and assign each sampler channel individually
716     a certain map, so that i.e. separation of normal instruments and
717     drumkits is possible
718 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
719     MIDI instrument maps, MIDI instruments, FX sends, global volume.
720 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
721     due to a constant size RingBuffer FIFO which is now replaced by a
722     dynamic (unlimited) size std::list FIFO
723 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
724     output channels for being processed by external effect processors
725     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
726     controllers
727 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
728 iliev 1130 - Implemented new, improved notification system
729 schoenebeck 1149 - fixed compilation errors regarding OSX
730     (patch by Toshi Nagata)
731 iliev 1161 - implemented instruments database
732 iliev 1345 - added support for escape sequences to the instruments database
733 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
734     within the sampler's process (by using instrument editor plugins),
735     you'll notice the new "Registered instrument editors:" message on
736 schoenebeck 1407 startup, added a new LSCP command:
737     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
738 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
739     given sampler channel, the plugin path can be overridden at compile
740     time with ./configure --enable-plugin-dir=/some/dir
741 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
742     in the sampler's process to safely edit instruments while playing
743     without a crash (hopefully) by either suspending single regions
744     wherever possible or if unavoidable whole engine(s)
745 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
746     policy and priority on thread level, set a minimum stack size for
747     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
748     threads simply inherited properties of starting thread instead of
749     setting their own policy and priority
750 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
751     main process did not wait for the stack trace process to finish
752     its output
753 persson 1248 - fixed some minor memory leaks
754 schoenebeck 1259 - reenabled assembly features support, at the moment only for
755     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
756 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
757     register, to avoid relocations in the text segment at runtime)
758 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
759 schoenebeck 947
760     * MIDI driver:
761     - dispatch bank select (MSB and LSB) messages
762    
763 schoenebeck 1049 * audio driver:
764     - the ALSA audio output driver parameters now reflect the correct
765     parameter value ranges for the respective selected sound card
766     (patch by Till Wimmer, a bit fixed and extended)
767    
768 persson 951 * Gigasampler format engine:
769     - if a filter is used and EG2 finishes before EG1, let the voice
770     die when EG2 has finished (this fixes a problem with clicks and
771     voice starvation for some gigs)
772 persson 1038 - playback is no longer disabled during instrument loading
773     - all notes playing on a channel that changes its instrument keep
774     playing with the old instrument until they get a note off
775     command
776 persson 1039 - EG fix: a release value of zero could cause noises or crash
777 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
778 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
779     above max sustain level, which means that there is a decay phase
780     even if sustain is 100%
781 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
782     noises or crashes
783 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
784 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
785     supplied to the configure script (fixes #46)
786 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
787     instead of a fix value
788 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
789     127 (solo mode) only kill voices if the respective mode really
790     changed
791 persson 951
792 schoenebeck 1244 * LSCP server:
793     - fixed compile time error for old Bison versions
794     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
795 schoenebeck 1245 - parser now supports extended ASCII character set
796     (up to ASCII code 255, i.e. includes now umlauts and accents)
797     - filename arguments in LSCP commands now allow to use escape
798     sequences, that is directly literal as one of: \', \", \\, \n, \r,
799     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
800     code value like \xf2) (fixes bug #24)
801 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
802     least one of their text-based parameters (i.e. name, description):
803     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
804     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
805     "SET DB_INSTRUMENT_DIRECTORY NAME",
806     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
807     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
808     "FIND DB_INSTRUMENT_DIRECTORIES"
809 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
810     occured, the unexpected character and the actually expected, possible
811     character(s), the latter only if less than 5 possibilities)
812 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
813     settings
814 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
815     of strings were treated as being one string containing commas
816     (fixes #57)
817 schoenebeck 1244
818 iliev 959 * Bug fixes:
819     - fixed crash occurring on certain LSCP scripts (Bug 39)
820 persson 1038 - another thread safety fix for lscp "load engine" and "set
821     channel audio output device"
822 iliev 1283 - fixed a crash which occurs when reassigning the same engine
823     on a sampler channel with connected MIDI device
824 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
825     device connected to a sampler channel to number less then or equal
826     to the index of the port to which the sampler channel is connected.
827 iliev 1296 - The previous bindings were not been disconnected when altering
828     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
829     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
830 iliev 1297 - The active stream/voice count statistic was incorrect.
831 iliev 1298 - notification events were not been sent for some sampler
832     channel changes
833 iliev 1305 - added default min and max values to restrict the number of allowed
834     audio output channels and MIDI input ports
835 iliev 1306 - the connection to the PCM interface is now closed when destroying
836     an audio output device
837 schoenebeck 1332 - files with slash in their path or filename could not be loaded
838 iliev 959
839 schoenebeck 1221 * test cases:
840     - updated and fixed (haven't been touched in a while)
841    
842 schoenebeck 937 Version 0.4.0 (24 November 2006)
843 persson 696
844 schoenebeck 697 * packaging changes:
845 capela 868 - changed deprecated copyright attribute to license; added ldconfig
846     to post-(un)install steps; added devel package for liblinuxsampler;
847     to linuxsampler.spec (RPM)
848 schoenebeck 697 - install necessary development header files for allowing 3rd party
849     applications to link against liblinuxsampler
850     - liblinuxsampler's API documentation can be generated with 'make docs'
851     (Doxygen required)
852 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
853     implementation (currently either an integer math solution or a
854     di-harmonic approximation), automatic detection can be overriden
855     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
856     configure script argument though (mandatory for cross-compilation)
857 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
858     provided some on his own (as CXXFLAGS)
859 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
860     messages
861 schoenebeck 852 - added compile time options to allow disabling the various audio and
862     MIDI drivers
863 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
864     (patch by Ebrahim Mayat)
865 schoenebeck 697
866 persson 696 * Gigasampler format engine:
867 schoenebeck 738 - extensive synthesis optimization
868     (reimplementation of EGs and LFO(s), removed synthesis parameter
869     prerendering and the synthesis parameter matrix in general, splitting
870     each audio fragment into subfragments now where each subfragment uses
871 persson 830 constant pitch and filter coefficients. The volume coefficient is
872     linearly interpolated inside a subfragment, unless
873     --disable-interpolate-volume is set.)
874 persson 696 - fine tuning of the EG modulation parameters
875 persson 729 - improved filter cutoff calculation by adding support for the
876     following gig parameters: Cutoff freq (used when no cutoff
877     controller is defined), Control invert, Minimum cutoff, Velocity
878 persson 791 curve and Velocity range. The keyboard tracking now scales
879     cutoff frequency instead of resonance.
880 persson 877 - added support for gig parameter Resonance.
881 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
882 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
883     which can be overridden with --enable-global-attenuation
884 persson 783 - EG fixes: made the length of "attack hold" stage more
885     accurate. Release stage can now start before attack stage
886 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
887     time now has a minimal value to prevent clicks.
888 persson 799 - fixed pitch changes larger than one octave
889 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
890     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
891     all modes can be altered via standard GM messages, that is CC5 for
892     altering portamento time, CC65 for enabling / disabling portamento
893     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
894 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
895     parameter) and crossfade
896 persson 831 - added support for the "attenuation controller threshold" gig
897     parameter
898 persson 832 - added smoothing of volume changes caused by control change
899     messages
900 persson 865 - sample loop parameters are now taken from the DimensionRegion
901     instead of the wave chunk
902     - fixed keyswitching for v3 gigs with a number of keyswitch splits
903     not equal to a power of two
904 persson 877 - reimplementation of the filter algorithm. The new filter is more
905     accurate and supports all gig filter types, including bandreject
906     and lowpass turbo.
907 persson 903 - real support for 24 bit samples - samples are not truncated to
908     16 bits anymore
909     - support for aftertouch (channel pressure, not polyphonic
910     aftertouch)
911 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
912     amplifying from 0)
913 persson 696
914 schoenebeck 711 * LSCP server:
915     - fixed application exit on broken pipe error (fixes bug #20)
916 iliev 793 - fixed the notification messages delay due to lack of
917     network activity (fixes bug #26)
918 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
919     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
920 schoenebeck 711
921 schoenebeck 838 * audio driver:
922     - added aRts audio output driver (by no means RT safe)
923    
924 schoenebeck 775 * MIDI driver:
925     - fixed legacy sysex code which caused dispatching of MIDI SysEx
926     messages several times instead of once
927 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
928     for events (i.e. for offline rendering based MIDI drivers)
929 persson 922 - added checks for bad MIDI data
930 schoenebeck 775
931 schoenebeck 900 * linuxsampler application:
932     - show available sampler engine types on startup
933    
934 schoenebeck 705 * general changes:
935     - support for muting sampler channels and solo mode of the same, two new
936     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
937     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
938     introduced for this, the behavior is the same like on a mixer console
939 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
940     --enable-process-muted-channels which can be used to enable the
941     processing of muted channels.
942 iliev 777 - support for sostenuto pedal
943 iliev 779 - support for monitoring the total number of active voices
944 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
945     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
946 persson 835 - fixed some memory management errors
947 persson 841 - fixed some concurrency problems that could lead to crashes when
948     LSCP commands were executed
949 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
950     sampler channel (fixes bug #36)
951 schoenebeck 705
952 schoenebeck 692 Version 0.3.3 (15 July 2005)
953 schoenebeck 686
954     * packaging changes:
955     - fixed compilation with gcc 4.0
956    
957 schoenebeck 687 * Gigasampler format engine:
958     - LFO preprocessing was performed even though the respective LFO was
959     disabled by the instrument patch (minor efficiency fix)
960 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
961     for volume ramp downs in the same fragment (needed for current voice
962     stealing implementation) then simply inform the user with a warning
963     about possible click sounds and reduce the volume ramp down
964     appropriately instead of cancelling the audio device connection
965 schoenebeck 687
966 schoenebeck 677 Version 0.3.2 (24 June 2005)
967 schoenebeck 609
968     * packaging changes:
969     - updated autotools build files to compile on OS X
970     (conditional compilation of CoreMIDI and MidiShare drivers)
971 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
972     './configure --disable-asm' (definitely not recommended)
973 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
974     - require automake (>= 1.5) for 'make -f Makefile.cvs'
975     (due to 'dist-bzip2' automake option)
976 schoenebeck 649
977     * Gigasampler format engine:
978     - support for the gig parameters for "release velocity response" curves
979     - fine tuning of the EGADSR envelope
980     - volume of release triggered samples now depends on note-on velocity,
981     note length and gig parameter "release trigger decay" instead of
982     note-off velocity.
983 schoenebeck 663 - revised voice stealing
984     (fixes crash and endless loop caused by voice stealing)
985 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
986 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
987     instead of when the respective voice is actually launched
988     (fixes undefined behavior if stolen voices belonged to a key group -
989     this case was followed by a "killed voice survived" error message)
990 schoenebeck 669 - fixed minor issue with null/silence samples
991     (those stole voices even though they don't need a voice at all which
992     resulted in "voice stealing didn't work out" messages)
993 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
994     instrument or audio output device change
995 schoenebeck 654
996 schoenebeck 620 * LSCP server:
997 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
998 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
999 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
1000 schoenebeck 609
1001 schoenebeck 668 * linuxsampler application:
1002     - added command line parameters --lscp-addr and --lscp-port to override
1003     default IP address and port of LSCP server
1004    
1005 schoenebeck 579 Version 0.3.1 (24 May 2005)
1006    
1007     * initial release
