* Bugfix in VirtualMidiDevice: process note on with velocity 0 as note off.

1 schoenebeck 1993 Version CVS HEAD (?)
2    
3 persson 2086 * packaging changes:
4     - fixed building with newer MinGW-w64
5 persson 2183 - Mac OS X: support the new dir for Core Audio SDK
6     - Mac OS X: fixed building outside source directory
7     - made sure all source files for hostplugins are included when
8     doing "make dist"
9     - removed empty directories left from the cvs to svn migration
10 persson 2185 - fixed compilation with gcc 4.6.1
11 persson 2203 - another "make dist" fix, for the LV2 plugin
12 persson 2185 - made --enable-pthread-testcancel default on Mac OS X
13 persson 2197 - minor Makefile fix for building lscpparser when build and source
14     directories are separate
15 persson 2203 - Mac OS X: made it possible to specify plugin installation dir to
16     configure
17 persson 2208 - Mac OS X: Makefile fix for the install-strip target
18 persson 2335 - fixed compilation with gcc 4.7
19 persson 2343 - fixed configure script error with old autoconf versions

22 persson 2365 - modernized configure script
23 persson 2378 - fixed linkage error when building with
24     LDFLAGS="-Wl,--no-undefined" (#190)
25 persson 2382
26 persson 2086 * general changes:
27 iliev 2012 - Refactoring: moved the independent code from
28     the Gigasampler format engine to base classes
29 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
30     respective profiling code is currently broken
31 schoenebeck 2053 - Introduced support for optional environment variable
32     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
33     where the sampler shall look for instrument editor plugins
34     (patch by Luis Garrido, slightly modified).
35 schoenebeck 2121 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
36     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
37     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
38     note (in this implementation of the sampler its simply hard routed to
39     the 1st effect send of the sampler channel, no matter what the actual
40     effect type is)
41     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
42     note (in this implementation of the sampler its simply hard routed to
43     the 2nd effect send of the sampler channel, no matter what the actual
44     effect type is)
45 schoenebeck 2124 - implemented support for internal LADSPA effects
46 schoenebeck 2140 - raised limit of program change queue from 100 to 512
47     (as suggested by Alex Stone)

52     EngineChannel::InstrumentFileName(int index)
53     allowing to retrieve the whole list of files used for the loaded
54     instrument on an engine channel (a.k.a. part). Some GigaStudio
55     instruments for example are splitted over several files like
56     "Foo.gig", "Foo.gx01", "Foo.gx02", ...
57 schoenebeck 2375 - Added new C++ API method Sampler::GetGlobalMaxVoices().
58     - Added new C++ API method Sampler::GetGlobalMaxStreams().

72 persson 2382 - bugfix: pitch LFO controller "internal+aftertouch" was broken
73     - bugfix: filter keyboard tracking was broken
74     - filter performance fix (an unnecessary copy was made of the

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

384 schoenebeck 1599
385 schoenebeck 1639 * packaging changes:
386     - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

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

448     - removed the nonsense audio channel constraint (which was hard coded to
449     max. 100 audio channels) for most audio drivers
450 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
451     opposed to the LSCP specs

457 persson 1748 jack_client_new
458 iliev 1829 - added (experimental) CoreAudio driver
459 persson 1888 - applied old fixes to the ASIO driver that were included in the
460     previous binary release but accidentally never committed to CVS
461     (fixes #117)
462 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
463     win64)

474     AudioChannel::CopyTo() methods using GCC vector exensions
475     (if available)
476 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
477     exception when getting parameters from a disconnected device
478 schoenebeck 1599
479 persson 1651 * MIDI driver:
480     - added JACK MIDI driver
481 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
482     want to (mis)use it for some purpose ("fixed" in all current MIDI
483     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
484 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
485 persson 1887 CoreMidi or AU
486 persson 1889 - fixed mingw-w64 compilation error in MME driver
487 persson 1924 - made program change handling in MIDI thread real-time safe by

493     to the instruments database
494 iliev 1727 - added support for handling lost files in the instruments database
495 iliev 1781 - Implemented option for adding instruments in separate directories
496     in the instruments database

498 persson 1908 - work-around for missing fnmatch function on Windows to make
499     instrument database compilable
500 schoenebeck 1930 - added instrument database support on Windows
501     works with both standalone mode and VST plugin.
502     the instruments DB file is located in
503     %USERPROFILE%\.linuxsampler\instruments.db which allows different
504     databases for each windows user
505     if no DB is present it automatically creates the .linuxsampler subdir
506     and then creates an empty DB
507 persson 1943 - fixed recursive import, which was broken on Windows
508 iliev 1603
509 persson 1644 * Gigasampler format engine:
510     - fixed a memory leak that could happen when a channel was deleted

512 persson 1646 - made it possible to load an instrument even if the audio thread
513     isn't running
514 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
515     enough for piano gigs with pedal noise samples
516 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
517     respective FX send MIDI controller was used
518 schoenebeck 1724 - added support for GM global device volume SysEx message
519 schoenebeck 1762 (can be selected at compile time to either apply globally to the
520     whole sampler [default] or only to the sampler channels that are
521     connected to the respective MIDI input port the SysEx message arrived
522     on)
523 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
524     sometimes wrongly killed in the same buffer, causing no sound to
525     be played
526 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
527     which is usally used to switch a part between chromatic sounds and
528     drumkit sounds (as opposed to their common default setting of MIDI
529     part 10 being a drumkit part and all other ones chromatic parts), in
530     LS however one can switch between the first 16 MIDI instrument maps
531     defined for the sampler
532 persson 1764 - made it possible to create multiple sample channels even if the
533     audio thread isn't running
534 persson 1844 - fixed crash when removing channel with active voices (#116)
535 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
536     un-cache the respective sample if it's really not used by any
537     sampler engine anymore
538     - re-cache samples in case they were changed by an instrument editor,
539     e.g. when a sample was added while playing (#82)
540 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
541     same time stamp as the voice's note-on event and occured both in the
542     same audio fragment cycle (fixes bug #112)
543 persson 1858 - added support for the "fine tune" and "pitch bend range"
544     instrument-level gig parameters
545     - fixed minor artifacts in pitch bend handling
546 schoenebeck 1860 - added support for GS Reset SysEx message
547 persson 1862 - allow gig files to use unlimited downward pitch shifting
548     - added a limit check for upward pitch shifting
549 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
550     note was silent
551 persson 1923 - fixed crash happening when a pitch bend event arrived at the
552     same time a new instrument was loading
553 persson 1644
554 schoenebeck 1687 * LSCP server:
555     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
556     react on MIDI data arriving on certain sampler channels (so far only
557     Note-On and Note-Off events are sent via this LSCP event)
558 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
559     react on MIDI data arriving on certain MIDI input devices (so far only
560     Note-On and Note-Off events are sent via this LSCP event)
561 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
562     SET DB_INSTRUMENT FILE_PATH
563 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
564     frontends to send MIDI messages to specific sampler channel
565     - added two additional fields to GET FILE INSTRUMENT INFO command -
566     KEY_BINDINGS and KEYSWITCH_BINDINGS
567 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
568     was incorrect
569 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
570 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
571     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
572     be triggered respectively
573     - added new LSCP command "SET STREAMS" to globally alter the maximum
574     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
575     which will be triggered respectively
576 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
577     a gigedit file dialog is opened)
578 iliev 1848 - close all connections when LSCPServer is deleted
579 iliev 1882 - hard close of all sockets on exit
580 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
581     driver
582 schoenebeck 1687
583 iliev 1761 * Bug fixes:
584     - fixed a crash which occurs when removing a sampler channel waiting
585     to start instrument loading after another channel
586 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
587     instrument loading in progress (bug #113)
588 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
589     instrument with PERSISTENT load mode
590 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
591     - fixed memory leaks when issuing the following LSCP commands:
592     GET AUDIO_OUTPUT_DRIVER INFO
593     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
594     GET MIDI_INPUT_DRIVER INFO
595     GET MIDI_INPUT_DRIVER_PARAMETER INFO
596     - fixed possible compilation error when sqlite is not present
597 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
598 iliev 1847 - fixed crash when changing the audio output device of a sampler
599     channel with loaded instrument and start playing notes
600 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
601 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
602     PowerPC, which probably could cause crashes on that platform
603 persson 1889 - fixed a memory management error which could cause a crash when a
604     plugin was unloaded
605 persson 1896 - bugfix: two private structs had the same name, which could cause
606     problems if the linker chose the wrong constructor
607 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
608     Windows
609 iliev 1761
610    
611 schoenebeck 1560 Version 0.5.1 (6 December 2007)
612 schoenebeck 1454
613     * packaging changes:
614     - added autoconf checks for pthread library
615     - added autoconf check for pthread bug found on certain NPTL-enabled
616     glibc versions (see Gentoo bug report #194076)
617 senoner 1502 - added autoconf checks for MS Windows
618 schoenebeck 1454
619 persson 1455 * general changes:
620     - bugfix: the thread used by an editor plugin didn't die when the
621     editor closed
622 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
623     out all the space. operator--() did not apply size_mask after
624     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
625     order to avoid problems with the _NonVolatileReader functions.
626     - bugfix: Stream.h: added a missing divide by BytesPerSample in
627     GetWriteSpace(). Since this function is currently only used in
628     the stream's qsort() compare function, it didn't trigger any
629     bugs.
630     - Resampler.h, Synthesizer.h: cubic interpolation now works in
631     24bit mode too. Faster method to read 24bit words on little
632     endian machines (x86): replaced 3 byte reads + shifts with a 1
633     unaligned 32bit read and shift
634     - experimental support for MS Windows (MIDI input via MME, AUDIO
635     output via ASIO)
636     - made handling of SIGINT signal (Ctrl-C) a bit more robust
637 iliev 1541 - support for monitoring the total number of active disk streams
638     (new LSCP commands: GET TOTAL_STREAM_COUNT,
639     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
640 persson 1455
641 senoner 1500 * AUDIO driver:
642 persson 1534 - added Windows ASIO low latency audio driver
643 senoner 1500
644 senoner 1485 * MIDI driver:
645 schoenebeck 1495 - added MME Windows MIDI driver
646 senoner 1485
647 schoenebeck 1471 * LSCP server:
648     - added support for Windows style path / filenames, however with
649     forward slash path separators instead of backslash
650     (i.e. "C:/foo/bar.gig")
651 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
652     apostrophes as well
653 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
654     "LIST FILE INSTRUMENTS <file>" and
655     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
656     about an arbitrary instrument file on the system where the sampler is
657     running on
658 schoenebeck 1471
659 schoenebeck 1424 Version 0.5.0 (15 October 2007)
660 schoenebeck 947
661 schoenebeck 1065 * packaging changes:
662 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
663     API header files anymore
664 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
665     the Doxygen API documentation (explicitly listed in Doxyfile.in)
666 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
667     capable to execute our autoconf environment, thus no need anymore
668     to maintain the compile time configuration file (osx/version.h) for
669     OSX manually (patch by Toshi Nagata)
670 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
671     parameters
672 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
673     C++ API header files, all implementation internal global definitions
674     are now in global_private.h
675     - atomic.h is not exposed to the C++ API anymore
676     - no need to include config.h anymore for using LS's API header files
677     - fixed warnings in API doc generation
678 schoenebeck 1065
679 schoenebeck 947 * general changes:
680     - replaced the old, confusing MIDI program change mechanism by a
681     flexible MIDI instrument mapper which allows to map arbitrary
682 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
683 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
684     loaded on the respective channel when such MIDI program change
685     messages arrive, beside that, each entry allows to define a life-time
686     strategy for the instrument, so the user can define whether the
687     instrument should i.e. be permanently loaded (to be able to switch
688     quickly among sounds) or i.e. loaded just on demand when the
689     respective program change arrives (to safe RAM space), as well as a
690     global volume factor for each entry, so the user can adjust the volume
691     dynamic of his mapped instrument collection without having to modify
692 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
693     MIDI instrument maps and assign each sampler channel individually
694     a certain map, so that i.e. separation of normal instruments and
695     drumkits is possible
696 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
697     MIDI instrument maps, MIDI instruments, FX sends, global volume.
698 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
699     due to a constant size RingBuffer FIFO which is now replaced by a
700     dynamic (unlimited) size std::list FIFO
701 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
702     output channels for being processed by external effect processors
703     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
704     controllers
705 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
706 iliev 1130 - Implemented new, improved notification system
707 schoenebeck 1149 - fixed compilation errors regarding OSX
708     (patch by Toshi Nagata)
709 iliev 1161 - implemented instruments database
710 iliev 1345 - added support for escape sequences to the instruments database
711 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
712     within the sampler's process (by using instrument editor plugins),
713     you'll notice the new "Registered instrument editors:" message on
714 schoenebeck 1407 startup, added a new LSCP command:
715     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
716 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
717     given sampler channel, the plugin path can be overridden at compile
718     time with ./configure --enable-plugin-dir=/some/dir
719 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
720     in the sampler's process to safely edit instruments while playing
721     without a crash (hopefully) by either suspending single regions
722     wherever possible or if unavoidable whole engine(s)
723 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
724     policy and priority on thread level, set a minimum stack size for
725     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
726     threads simply inherited properties of starting thread instead of
727     setting their own policy and priority
728 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
729     main process did not wait for the stack trace process to finish
730     its output
731 persson 1248 - fixed some minor memory leaks
732 schoenebeck 1259 - reenabled assembly features support, at the moment only for
733     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
734 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
735     register, to avoid relocations in the text segment at runtime)
736 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
737 schoenebeck 947
738     * MIDI driver:
739     - dispatch bank select (MSB and LSB) messages
740    
741 schoenebeck 1049 * audio driver:
742     - the ALSA audio output driver parameters now reflect the correct
743     parameter value ranges for the respective selected sound card
744     (patch by Till Wimmer, a bit fixed and extended)
745    
746 persson 951 * Gigasampler format engine:
747     - if a filter is used and EG2 finishes before EG1, let the voice
748     die when EG2 has finished (this fixes a problem with clicks and
749     voice starvation for some gigs)
750 persson 1038 - playback is no longer disabled during instrument loading
751     - all notes playing on a channel that changes its instrument keep
752     playing with the old instrument until they get a note off
753     command
754 persson 1039 - EG fix: a release value of zero could cause noises or crash
755 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
756 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
757     above max sustain level, which means that there is a decay phase
758     even if sustain is 100%
759 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
760     noises or crashes
761 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
762 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
763     supplied to the configure script (fixes #46)
764 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
765     instead of a fix value
766 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
767     127 (solo mode) only kill voices if the respective mode really
768     changed
769 persson 951
770 schoenebeck 1244 * LSCP server:
771     - fixed compile time error for old Bison versions
772     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
773 schoenebeck 1245 - parser now supports extended ASCII character set
774     (up to ASCII code 255, i.e. includes now umlauts and accents)
775     - filename arguments in LSCP commands now allow to use escape
776     sequences, that is directly literal as one of: \', \", \\, \n, \r,
777     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
778     code value like \xf2) (fixes bug #24)
779 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
780     least one of their text-based parameters (i.e. name, description):
781     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
782     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
783     "SET DB_INSTRUMENT_DIRECTORY NAME",
784     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
785     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
786     "FIND DB_INSTRUMENT_DIRECTORIES"
787 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
788     occured, the unexpected character and the actually expected, possible
789     character(s), the latter only if less than 5 possibilities)
790 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
791     settings
792 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
793     of strings were treated as being one string containing commas
794     (fixes #57)
795 schoenebeck 1244
796 iliev 959 * Bug fixes:
797     - fixed crash occurring on certain LSCP scripts (Bug 39)
798 persson 1038 - another thread safety fix for lscp "load engine" and "set
799     channel audio output device"
800 iliev 1283 - fixed a crash which occurs when reassigning the same engine
801     on a sampler channel with connected MIDI device
802 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
803     device connected to a sampler channel to number less then or equal
804     to the index of the port to which the sampler channel is connected.
805 iliev 1296 - The previous bindings were not been disconnected when altering
806     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
807     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
808 iliev 1297 - The active stream/voice count statistic was incorrect.
809 iliev 1298 - notification events were not been sent for some sampler
810     channel changes
811 iliev 1305 - added default min and max values to restrict the number of allowed
812     audio output channels and MIDI input ports
813 iliev 1306 - the connection to the PCM interface is now closed when destroying
814     an audio output device
815 schoenebeck 1332 - files with slash in their path or filename could not be loaded
816 iliev 959
817 schoenebeck 1221 * test cases:
818     - updated and fixed (haven't been touched in a while)
819    
820 schoenebeck 937 Version 0.4.0 (24 November 2006)
821 persson 696
822 schoenebeck 697 * packaging changes:
823 capela 868 - changed deprecated copyright attribute to license; added ldconfig
824     to post-(un)install steps; added devel package for liblinuxsampler;
825     to linuxsampler.spec (RPM)
826 schoenebeck 697 - install necessary development header files for allowing 3rd party
827     applications to link against liblinuxsampler
828     - liblinuxsampler's API documentation can be generated with 'make docs'
829     (Doxygen required)
830 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
831     implementation (currently either an integer math solution or a
832     di-harmonic approximation), automatic detection can be overriden
833     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
834     configure script argument though (mandatory for cross-compilation)
835 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
836     provided some on his own (as CXXFLAGS)
837 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
838     messages
839 schoenebeck 852 - added compile time options to allow disabling the various audio and
840     MIDI drivers
841 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
842     (patch by Ebrahim Mayat)
843 schoenebeck 697
844 persson 696 * Gigasampler format engine:
845 schoenebeck 738 - extensive synthesis optimization
846     (reimplementation of EGs and LFO(s), removed synthesis parameter
847     prerendering and the synthesis parameter matrix in general, splitting
848     each audio fragment into subfragments now where each subfragment uses
849 persson 830 constant pitch and filter coefficients. The volume coefficient is
850     linearly interpolated inside a subfragment, unless
851     --disable-interpolate-volume is set.)
852 persson 696 - fine tuning of the EG modulation parameters
853 persson 729 - improved filter cutoff calculation by adding support for the
854     following gig parameters: Cutoff freq (used when no cutoff
855     controller is defined), Control invert, Minimum cutoff, Velocity
856 persson 791 curve and Velocity range. The keyboard tracking now scales
857     cutoff frequency instead of resonance.
858 persson 877 - added support for gig parameter Resonance.
859 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
860 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
861     which can be overridden with --enable-global-attenuation
862 persson 783 - EG fixes: made the length of "attack hold" stage more
863     accurate. Release stage can now start before attack stage
864 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
865     time now has a minimal value to prevent clicks.
866 persson 799 - fixed pitch changes larger than one octave
867 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
868     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
869     all modes can be altered via standard GM messages, that is CC5 for
870     altering portamento time, CC65 for enabling / disabling portamento
871     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
872 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
873     parameter) and crossfade
874 persson 831 - added support for the "attenuation controller threshold" gig
875     parameter
876 persson 832 - added smoothing of volume changes caused by control change
877     messages
878 persson 865 - sample loop parameters are now taken from the DimensionRegion
879     instead of the wave chunk
880     - fixed keyswitching for v3 gigs with a number of keyswitch splits
881     not equal to a power of two
882 persson 877 - reimplementation of the filter algorithm. The new filter is more
883     accurate and supports all gig filter types, including bandreject
884     and lowpass turbo.
885 persson 903 - real support for 24 bit samples - samples are not truncated to
886     16 bits anymore
887     - support for aftertouch (channel pressure, not polyphonic
888     aftertouch)
889 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
890     amplifying from 0)
891 persson 696
892 schoenebeck 711 * LSCP server:
893     - fixed application exit on broken pipe error (fixes bug #20)
894 iliev 793 - fixed the notification messages delay due to lack of
895     network activity (fixes bug #26)
896 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
897     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
898 schoenebeck 711
899 schoenebeck 838 * audio driver:
900     - added aRts audio output driver (by no means RT safe)
901    
902 schoenebeck 775 * MIDI driver:
903     - fixed legacy sysex code which caused dispatching of MIDI SysEx
904     messages several times instead of once
905 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
906     for events (i.e. for offline rendering based MIDI drivers)
907 persson 922 - added checks for bad MIDI data
908 schoenebeck 775
909 schoenebeck 900 * linuxsampler application:
910     - show available sampler engine types on startup
911    
912 schoenebeck 705 * general changes:
913     - support for muting sampler channels and solo mode of the same, two new
914     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
915     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
916     introduced for this, the behavior is the same like on a mixer console
917 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
918     --enable-process-muted-channels which can be used to enable the
919     processing of muted channels.
920 iliev 777 - support for sostenuto pedal
921 iliev 779 - support for monitoring the total number of active voices
922 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
923     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
924 persson 835 - fixed some memory management errors
925 persson 841 - fixed some concurrency problems that could lead to crashes when
926     LSCP commands were executed
927 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
928     sampler channel (fixes bug #36)
929 schoenebeck 705
930 schoenebeck 692 Version 0.3.3 (15 July 2005)
931 schoenebeck 686
932     * packaging changes:
933     - fixed compilation with gcc 4.0
934    
935 schoenebeck 687 * Gigasampler format engine:
936     - LFO preprocessing was performed even though the respective LFO was
937     disabled by the instrument patch (minor efficiency fix)
938 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
939     for volume ramp downs in the same fragment (needed for current voice
940     stealing implementation) then simply inform the user with a warning
941     about possible click sounds and reduce the volume ramp down
942     appropriately instead of cancelling the audio device connection
943 schoenebeck 687
944 schoenebeck 677 Version 0.3.2 (24 June 2005)
945 schoenebeck 609
946     * packaging changes:
947     - updated autotools build files to compile on OS X
948     (conditional compilation of CoreMIDI and MidiShare drivers)
949 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
950     './configure --disable-asm' (definitely not recommended)
951 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
952     - require automake (>= 1.5) for 'make -f Makefile.cvs'
953     (due to 'dist-bzip2' automake option)
954 schoenebeck 649
955     * Gigasampler format engine:
956     - support for the gig parameters for "release velocity response" curves
957     - fine tuning of the EGADSR envelope
958     - volume of release triggered samples now depends on note-on velocity,
959     note length and gig parameter "release trigger decay" instead of
960     note-off velocity.
961 schoenebeck 663 - revised voice stealing
962     (fixes crash and endless loop caused by voice stealing)
963 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
964 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
965     instead of when the respective voice is actually launched
966     (fixes undefined behavior if stolen voices belonged to a key group -
967     this case was followed by a "killed voice survived" error message)
968 schoenebeck 669 - fixed minor issue with null/silence samples
969     (those stole voices even though they don't need a voice at all which
970     resulted in "voice stealing didn't work out" messages)
971 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
972     instrument or audio output device change
973 schoenebeck 654
974 schoenebeck 620 * LSCP server:
975 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
976 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
977 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
978 schoenebeck 609
979 schoenebeck 668 * linuxsampler application:
980     - added command line parameters --lscp-addr and --lscp-port to override
981     default IP address and port of LSCP server
982    
983 schoenebeck 579 Version 0.3.1 (24 May 2005)
984    
985     * initial release
