* VST: implemented retrieval and switching of programs using the
  sampler's internal MIDI instrument mapping system
* VST: reply to "canDo" plugin features we don't know as "don't know"
* bumped version to 1.0.0.svn19

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

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

47 iliev 2296 - experimental support for per voice equalization
48 iliev 2306 - added command line option --exec-after-init
49 schoenebeck 2330 - Introduced new C++ API method:
50     EngineChannel::InstrumentFileName(int index)
51     allowing to retrieve the whole list of files used for the loaded
52     instrument on an engine channel (a.k.a. part). Some GigaStudio
53     instruments for example are splitted over several files like
54     "Foo.gig", "Foo.gx01", "Foo.gx02", ...
55 iliev 2012
56 persson 2043 * Gigasampler format engine:

280     - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
281     the driver will automatically connect to other CoreMIDI clients' ports

334     refresh) could cause instruments to be unloaded
335 persson 2183 - Mac OS X: fixed name collision of enum in EffectControl and
336     wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
337 persson 2185 - Mac OS X: fixed hanging threads
338 persson 2187 - Windows: disabled the previous thread fix on non-Mac systems, as
339     it caused hanging threads on Windows
340 iliev 2201 - Fixed possible crashes due to corrupted MIDI/audio device list
341     after MIDI/audio device creation failure
342 schoenebeck 2275 - When creating MIDI instrument map entries with "PERSISTENT" type, the
343     instruments were uselessly precached with zero samples, however it still
344     took the full preloading time and on 1st program change the respective
345     instrument was completely reloaded again.
346 persson 2277 - fixed handling of rapid bank select and program change messages
347     sent to the same sampler channel (patch from the Open Octave

366 schoenebeck 1599
367 schoenebeck 1639 * packaging changes:
368     - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

386 schoenebeck 1639
387 schoenebeck 1601 * general changes:

395     unnecessarily long after an update
396 schoenebeck 1653 - added support for notifying instrument editors on note-on / note-off
397     events (e.g. to highlight the pressed keys on the virtual keyboard
398     of gigedit)

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

412 persson 1825 - fixed CPU feature detection on x86_64 (maybe fixes #108)
413 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
414     be switched on by command line option "--stacktrace" (the automatic
415     stacktrace mechanism seems to be broken on most systems at the moment)
416 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
417     a pointer to the launched InstrumentEditor object
418 schoenebeck 1876 - added optional 3rd party user data parameter for following
419     liblinuxsampler C++ API methods: InstrumentEditor::Main(),

429 schoenebeck 1599 * audio driver:
430     - removed the nonsense audio channel constraint (which was hard coded to
431     max. 100 audio channels) for most audio drivers
432 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
433     opposed to the LSCP specs
434 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
435     reflected the wrong value
436 persson 1644 - fixed a memory management bug in ASIO driver
437 persson 1748 - Makefile fix: JACK_CFLAGS wasn't used

439 persson 1748 jack_client_new
440 iliev 1829 - added (experimental) CoreAudio driver
441 persson 1888 - applied old fixes to the ASIO driver that were included in the
442     previous binary release but accidentally never committed to CVS
443     (fixes #117)
444 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
445     win64)
446 persson 1895 - VST: added support for sample rate and buffer size changes
447     - VST: close editor (Fantasia) when the VST is removed

454     stored in the plugin state
455 schoenebeck 1930 - performance optimization of AudioChannel::MixTo() and
456     AudioChannel::CopyTo() methods using GCC vector exensions
457     (if available)
458 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
459     exception when getting parameters from a disconnected device
460 schoenebeck 1599
461 persson 1651 * MIDI driver:
462     - added JACK MIDI driver
463 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
464     want to (mis)use it for some purpose ("fixed" in all current MIDI
465     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
466 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
467 persson 1887 CoreMidi or AU
468 persson 1889 - fixed mingw-w64 compilation error in MME driver
469 persson 1924 - made program change handling in MIDI thread real-time safe by
470     moving the logic to a non-RT thread

475     to the instruments database
476 iliev 1727 - added support for handling lost files in the instruments database
477 iliev 1781 - Implemented option for adding instruments in separate directories
478     in the instruments database
479     (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
480 persson 1908 - work-around for missing fnmatch function on Windows to make
481     instrument database compilable
482 schoenebeck 1930 - added instrument database support on Windows
483     works with both standalone mode and VST plugin.
484     the instruments DB file is located in
485     %USERPROFILE%\.linuxsampler\instruments.db which allows different
486     databases for each windows user
487     if no DB is present it automatically creates the .linuxsampler subdir
488     and then creates an empty DB
489 persson 1943 - fixed recursive import, which was broken on Windows
490 iliev 1603
491 persson 1644 * Gigasampler format engine:
492     - fixed a memory leak that could happen when a channel was deleted
493     while notes were playing
494 persson 1646 - made it possible to load an instrument even if the audio thread
495     isn't running
496 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
497     enough for piano gigs with pedal noise samples
498 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
499     respective FX send MIDI controller was used
500 schoenebeck 1724 - added support for GM global device volume SysEx message
501 schoenebeck 1762 (can be selected at compile time to either apply globally to the
502     whole sampler [default] or only to the sampler channels that are
503     connected to the respective MIDI input port the SysEx message arrived
504     on)
505 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
506     sometimes wrongly killed in the same buffer, causing no sound to
507     be played
508 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
509     which is usally used to switch a part between chromatic sounds and
510     drumkit sounds (as opposed to their common default setting of MIDI
511     part 10 being a drumkit part and all other ones chromatic parts), in
512     LS however one can switch between the first 16 MIDI instrument maps
513     defined for the sampler
514 persson 1764 - made it possible to create multiple sample channels even if the
515     audio thread isn't running
516 persson 1844 - fixed crash when removing channel with active voices (#116)
517 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
518     un-cache the respective sample if it's really not used by any
519     sampler engine anymore
520     - re-cache samples in case they were changed by an instrument editor,
521     e.g. when a sample was added while playing (#82)
522 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
523     same time stamp as the voice's note-on event and occured both in the
524     same audio fragment cycle (fixes bug #112)
525 persson 1858 - added support for the "fine tune" and "pitch bend range"
526     instrument-level gig parameters
527     - fixed minor artifacts in pitch bend handling
528 schoenebeck 1860 - added support for GS Reset SysEx message
529 persson 1862 - allow gig files to use unlimited downward pitch shifting
530     - added a limit check for upward pitch shifting
531 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
532     note was silent
533 persson 1923 - fixed crash happening when a pitch bend event arrived at the
534     same time a new instrument was loading
535 persson 1644
536 schoenebeck 1687 * LSCP server:
537     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
538     react on MIDI data arriving on certain sampler channels (so far only
539     Note-On and Note-Off events are sent via this LSCP event)
540 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
541     react on MIDI data arriving on certain MIDI input devices (so far only
542     Note-On and Note-Off events are sent via this LSCP event)
543 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
544     SET DB_INSTRUMENT FILE_PATH
545 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
546     frontends to send MIDI messages to specific sampler channel
547     - added two additional fields to GET FILE INSTRUMENT INFO command -
548     KEY_BINDINGS and KEYSWITCH_BINDINGS
549 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
550     was incorrect
551 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
552 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
553     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
554     be triggered respectively
555     - added new LSCP command "SET STREAMS" to globally alter the maximum
556     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
557     which will be triggered respectively
558 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
559     a gigedit file dialog is opened)
560 iliev 1848 - close all connections when LSCPServer is deleted
561 iliev 1882 - hard close of all sockets on exit
562 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
563     driver
564 schoenebeck 1687
565 iliev 1761 * Bug fixes:
566     - fixed a crash which occurs when removing a sampler channel waiting
567     to start instrument loading after another channel
568 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
569     instrument loading in progress (bug #113)
570 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
571     instrument with PERSISTENT load mode
572 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
573     - fixed memory leaks when issuing the following LSCP commands:
574     GET AUDIO_OUTPUT_DRIVER INFO
575     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
576     GET MIDI_INPUT_DRIVER INFO
577     GET MIDI_INPUT_DRIVER_PARAMETER INFO
578     - fixed possible compilation error when sqlite is not present
579 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
580 iliev 1847 - fixed crash when changing the audio output device of a sampler
581     channel with loaded instrument and start playing notes
582 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
583 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
584     PowerPC, which probably could cause crashes on that platform
585 persson 1889 - fixed a memory management error which could cause a crash when a
586     plugin was unloaded
587 persson 1896 - bugfix: two private structs had the same name, which could cause
588     problems if the linker chose the wrong constructor
589 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
590     Windows
591 iliev 1761
592    
593 schoenebeck 1560 Version 0.5.1 (6 December 2007)
594 schoenebeck 1454
595     * packaging changes:
596     - added autoconf checks for pthread library
597     - added autoconf check for pthread bug found on certain NPTL-enabled
598     glibc versions (see Gentoo bug report #194076)
599 senoner 1502 - added autoconf checks for MS Windows
600 schoenebeck 1454
601 persson 1455 * general changes:
602     - bugfix: the thread used by an editor plugin didn't die when the
603     editor closed
604 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
605     out all the space. operator--() did not apply size_mask after
606     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
607     order to avoid problems with the _NonVolatileReader functions.
608     - bugfix: Stream.h: added a missing divide by BytesPerSample in
609     GetWriteSpace(). Since this function is currently only used in
610     the stream's qsort() compare function, it didn't trigger any
611     bugs.
612     - Resampler.h, Synthesizer.h: cubic interpolation now works in
613     24bit mode too. Faster method to read 24bit words on little
614     endian machines (x86): replaced 3 byte reads + shifts with a 1
615     unaligned 32bit read and shift
616     - experimental support for MS Windows (MIDI input via MME, AUDIO
617     output via ASIO)
618     - made handling of SIGINT signal (Ctrl-C) a bit more robust
619 iliev 1541 - support for monitoring the total number of active disk streams
620     (new LSCP commands: GET TOTAL_STREAM_COUNT,
621     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
622 persson 1455
623 senoner 1500 * AUDIO driver:
624 persson 1534 - added Windows ASIO low latency audio driver
625 senoner 1500
626 senoner 1485 * MIDI driver:
627 schoenebeck 1495 - added MME Windows MIDI driver
628 senoner 1485
629 schoenebeck 1471 * LSCP server:
630     - added support for Windows style path / filenames, however with
631     forward slash path separators instead of backslash
632     (i.e. "C:/foo/bar.gig")
633 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
634     apostrophes as well
635 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
636     "LIST FILE INSTRUMENTS <file>" and
637     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
638     about an arbitrary instrument file on the system where the sampler is
639     running on
640 schoenebeck 1471
641 schoenebeck 1424 Version 0.5.0 (15 October 2007)
642 schoenebeck 947
643 schoenebeck 1065 * packaging changes:
644 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
645     API header files anymore
646 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
647     the Doxygen API documentation (explicitly listed in Doxyfile.in)
648 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
649     capable to execute our autoconf environment, thus no need anymore
650     to maintain the compile time configuration file (osx/version.h) for
651     OSX manually (patch by Toshi Nagata)
652 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
653     parameters
654 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
655     C++ API header files, all implementation internal global definitions
656     are now in global_private.h
657     - atomic.h is not exposed to the C++ API anymore
658     - no need to include config.h anymore for using LS's API header files
659     - fixed warnings in API doc generation
660 schoenebeck 1065
661 schoenebeck 947 * general changes:
662     - replaced the old, confusing MIDI program change mechanism by a
663     flexible MIDI instrument mapper which allows to map arbitrary
664 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
665 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
666     loaded on the respective channel when such MIDI program change
667     messages arrive, beside that, each entry allows to define a life-time
668     strategy for the instrument, so the user can define whether the
669     instrument should i.e. be permanently loaded (to be able to switch
670     quickly among sounds) or i.e. loaded just on demand when the
671     respective program change arrives (to safe RAM space), as well as a
672     global volume factor for each entry, so the user can adjust the volume
673     dynamic of his mapped instrument collection without having to modify
674 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
675     MIDI instrument maps and assign each sampler channel individually
676     a certain map, so that i.e. separation of normal instruments and
677     drumkits is possible
678 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
679     MIDI instrument maps, MIDI instruments, FX sends, global volume.
680 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
681     due to a constant size RingBuffer FIFO which is now replaced by a
682     dynamic (unlimited) size std::list FIFO
683 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
684     output channels for being processed by external effect processors
685     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
686     controllers
687 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
688 iliev 1130 - Implemented new, improved notification system
689 schoenebeck 1149 - fixed compilation errors regarding OSX
690     (patch by Toshi Nagata)
691 iliev 1161 - implemented instruments database
692 iliev 1345 - added support for escape sequences to the instruments database
693 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
694     within the sampler's process (by using instrument editor plugins),
695     you'll notice the new "Registered instrument editors:" message on
696 schoenebeck 1407 startup, added a new LSCP command:
697     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
698 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
699     given sampler channel, the plugin path can be overridden at compile
700     time with ./configure --enable-plugin-dir=/some/dir
701 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
702     in the sampler's process to safely edit instruments while playing
703     without a crash (hopefully) by either suspending single regions
704     wherever possible or if unavoidable whole engine(s)
705 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
706     policy and priority on thread level, set a minimum stack size for
707     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
708     threads simply inherited properties of starting thread instead of
709     setting their own policy and priority
710 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
711     main process did not wait for the stack trace process to finish
712     its output
713 persson 1248 - fixed some minor memory leaks
714 schoenebeck 1259 - reenabled assembly features support, at the moment only for
715     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
716 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
717     register, to avoid relocations in the text segment at runtime)
718 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
719 schoenebeck 947
720     * MIDI driver:
721     - dispatch bank select (MSB and LSB) messages
722    
723 schoenebeck 1049 * audio driver:
724     - the ALSA audio output driver parameters now reflect the correct
725     parameter value ranges for the respective selected sound card
726     (patch by Till Wimmer, a bit fixed and extended)
727    
728 persson 951 * Gigasampler format engine:
729     - if a filter is used and EG2 finishes before EG1, let the voice
730     die when EG2 has finished (this fixes a problem with clicks and
731     voice starvation for some gigs)
732 persson 1038 - playback is no longer disabled during instrument loading
733     - all notes playing on a channel that changes its instrument keep
734     playing with the old instrument until they get a note off
735     command
736 persson 1039 - EG fix: a release value of zero could cause noises or crash
737 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
738 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
739     above max sustain level, which means that there is a decay phase
740     even if sustain is 100%
741 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
742     noises or crashes
743 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
744 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
745     supplied to the configure script (fixes #46)
746 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
747     instead of a fix value
748 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
749     127 (solo mode) only kill voices if the respective mode really
750     changed
751 persson 951
752 schoenebeck 1244 * LSCP server:
753     - fixed compile time error for old Bison versions
754     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
755 schoenebeck 1245 - parser now supports extended ASCII character set
756     (up to ASCII code 255, i.e. includes now umlauts and accents)
757     - filename arguments in LSCP commands now allow to use escape
758     sequences, that is directly literal as one of: \', \", \\, \n, \r,
759     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
760     code value like \xf2) (fixes bug #24)
761 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
762     least one of their text-based parameters (i.e. name, description):
763     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
764     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
765     "SET DB_INSTRUMENT_DIRECTORY NAME",
766     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
767     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
768     "FIND DB_INSTRUMENT_DIRECTORIES"
769 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
770     occured, the unexpected character and the actually expected, possible
771     character(s), the latter only if less than 5 possibilities)
772 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
773     settings
774 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
775     of strings were treated as being one string containing commas
776     (fixes #57)
777 schoenebeck 1244
778 iliev 959 * Bug fixes:
779     - fixed crash occurring on certain LSCP scripts (Bug 39)
780 persson 1038 - another thread safety fix for lscp "load engine" and "set
781     channel audio output device"
782 iliev 1283 - fixed a crash which occurs when reassigning the same engine
783     on a sampler channel with connected MIDI device
784 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
785     device connected to a sampler channel to number less then or equal
786     to the index of the port to which the sampler channel is connected.
787 iliev 1296 - The previous bindings were not been disconnected when altering
788     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
789     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
790 iliev 1297 - The active stream/voice count statistic was incorrect.
791 iliev 1298 - notification events were not been sent for some sampler
792     channel changes
793 iliev 1305 - added default min and max values to restrict the number of allowed
794     audio output channels and MIDI input ports
795 iliev 1306 - the connection to the PCM interface is now closed when destroying
796     an audio output device
797 schoenebeck 1332 - files with slash in their path or filename could not be loaded
798 iliev 959
799 schoenebeck 1221 * test cases:
800     - updated and fixed (haven't been touched in a while)
801    
802 schoenebeck 937 Version 0.4.0 (24 November 2006)
803 persson 696
804 schoenebeck 697 * packaging changes:
805 capela 868 - changed deprecated copyright attribute to license; added ldconfig
806     to post-(un)install steps; added devel package for liblinuxsampler;
807     to linuxsampler.spec (RPM)
808 schoenebeck 697 - install necessary development header files for allowing 3rd party
809     applications to link against liblinuxsampler
810     - liblinuxsampler's API documentation can be generated with 'make docs'
811     (Doxygen required)
812 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
813     implementation (currently either an integer math solution or a
814     di-harmonic approximation), automatic detection can be overriden
815     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
816     configure script argument though (mandatory for cross-compilation)
817 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
818     provided some on his own (as CXXFLAGS)
819 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
820     messages
821 schoenebeck 852 - added compile time options to allow disabling the various audio and
822     MIDI drivers
823 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
824     (patch by Ebrahim Mayat)
825 schoenebeck 697
826 persson 696 * Gigasampler format engine:
827 schoenebeck 738 - extensive synthesis optimization
828     (reimplementation of EGs and LFO(s), removed synthesis parameter
829     prerendering and the synthesis parameter matrix in general, splitting
830     each audio fragment into subfragments now where each subfragment uses
831 persson 830 constant pitch and filter coefficients. The volume coefficient is
832     linearly interpolated inside a subfragment, unless
833     --disable-interpolate-volume is set.)
834 persson 696 - fine tuning of the EG modulation parameters
835 persson 729 - improved filter cutoff calculation by adding support for the
836     following gig parameters: Cutoff freq (used when no cutoff
837     controller is defined), Control invert, Minimum cutoff, Velocity
838 persson 791 curve and Velocity range. The keyboard tracking now scales
839     cutoff frequency instead of resonance.
840 persson 877 - added support for gig parameter Resonance.
841 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
842 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
843     which can be overridden with --enable-global-attenuation
844 persson 783 - EG fixes: made the length of "attack hold" stage more
845     accurate. Release stage can now start before attack stage
846 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
847     time now has a minimal value to prevent clicks.
848 persson 799 - fixed pitch changes larger than one octave
849 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
850     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
851     all modes can be altered via standard GM messages, that is CC5 for
852     altering portamento time, CC65 for enabling / disabling portamento
853     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
854 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
855     parameter) and crossfade
856 persson 831 - added support for the "attenuation controller threshold" gig
857     parameter
858 persson 832 - added smoothing of volume changes caused by control change
859     messages
860 persson 865 - sample loop parameters are now taken from the DimensionRegion
861     instead of the wave chunk
862     - fixed keyswitching for v3 gigs with a number of keyswitch splits
863     not equal to a power of two
864 persson 877 - reimplementation of the filter algorithm. The new filter is more
865     accurate and supports all gig filter types, including bandreject
866     and lowpass turbo.
867 persson 903 - real support for 24 bit samples - samples are not truncated to
868     16 bits anymore
869     - support for aftertouch (channel pressure, not polyphonic
870     aftertouch)
871 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
872     amplifying from 0)
873 persson 696
874 schoenebeck 711 * LSCP server:
875     - fixed application exit on broken pipe error (fixes bug #20)
876 iliev 793 - fixed the notification messages delay due to lack of
877     network activity (fixes bug #26)
878 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
879     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
880 schoenebeck 711
881 schoenebeck 838 * audio driver:
882     - added aRts audio output driver (by no means RT safe)
883    
884 schoenebeck 775 * MIDI driver:
885     - fixed legacy sysex code which caused dispatching of MIDI SysEx
886     messages several times instead of once
887 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
888     for events (i.e. for offline rendering based MIDI drivers)
889 persson 922 - added checks for bad MIDI data
890 schoenebeck 775
891 schoenebeck 900 * linuxsampler application:
892     - show available sampler engine types on startup
893    
894 schoenebeck 705 * general changes:
895     - support for muting sampler channels and solo mode of the same, two new
896     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
897     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
898     introduced for this, the behavior is the same like on a mixer console
899 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
900     --enable-process-muted-channels which can be used to enable the
901     processing of muted channels.
902 iliev 777 - support for sostenuto pedal
903 iliev 779 - support for monitoring the total number of active voices
904 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
905     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
906 persson 835 - fixed some memory management errors
907 persson 841 - fixed some concurrency problems that could lead to crashes when
908     LSCP commands were executed
909 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
910     sampler channel (fixes bug #36)
911 schoenebeck 705
912 schoenebeck 692 Version 0.3.3 (15 July 2005)
913 schoenebeck 686
914     * packaging changes:
915     - fixed compilation with gcc 4.0
916    
917 schoenebeck 687 * Gigasampler format engine:
918     - LFO preprocessing was performed even though the respective LFO was
919     disabled by the instrument patch (minor efficiency fix)
920 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
921     for volume ramp downs in the same fragment (needed for current voice
922     stealing implementation) then simply inform the user with a warning
923     about possible click sounds and reduce the volume ramp down
924     appropriately instead of cancelling the audio device connection
925 schoenebeck 687
926 schoenebeck 677 Version 0.3.2 (24 June 2005)
927 schoenebeck 609
928     * packaging changes:
929     - updated autotools build files to compile on OS X
930     (conditional compilation of CoreMIDI and MidiShare drivers)
931 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
932     './configure --disable-asm' (definitely not recommended)
933 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
934     - require automake (>= 1.5) for 'make -f Makefile.cvs'
935     (due to 'dist-bzip2' automake option)
936 schoenebeck 649
937     * Gigasampler format engine:
938     - support for the gig parameters for "release velocity response" curves
939     - fine tuning of the EGADSR envelope
940     - volume of release triggered samples now depends on note-on velocity,
941     note length and gig parameter "release trigger decay" instead of
942     note-off velocity.
943 schoenebeck 663 - revised voice stealing
944     (fixes crash and endless loop caused by voice stealing)
945 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
946 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
947     instead of when the respective voice is actually launched
948     (fixes undefined behavior if stolen voices belonged to a key group -
949     this case was followed by a "killed voice survived" error message)
950 schoenebeck 669 - fixed minor issue with null/silence samples
951     (those stole voices even though they don't need a voice at all which
952     resulted in "voice stealing didn't work out" messages)
953 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
954     instrument or audio output device change
955 schoenebeck 654
956 schoenebeck 620 * LSCP server:
957 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
958 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
959 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
960 schoenebeck 609
961 schoenebeck 668 * linuxsampler application:
962     - added command line parameters --lscp-addr and --lscp-port to override
963     default IP address and port of LSCP server
964    
965 schoenebeck 579 Version 0.3.1 (24 May 2005)
966    
967     * initial release
