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

25 persson 2365
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

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().

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

340     a crash, or give "Handing back unknown region" error messages
341 persson 2165 - bugfix: calling SET VOICES (which Fantasia does on start and
342     refresh) could cause instruments to be unloaded
343 persson 2183 - Mac OS X: fixed name collision of enum in EffectControl and
344     wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
345 persson 2185 - Mac OS X: fixed hanging threads
346 persson 2187 - Windows: disabled the previous thread fix on non-Mac systems, as
347     it caused hanging threads on Windows
348 iliev 2201 - Fixed possible crashes due to corrupted MIDI/audio device list
349     after MIDI/audio device creation failure
350 schoenebeck 2275 - When creating MIDI instrument map entries with "PERSISTENT" type, the
351     instruments were uselessly precached with zero samples, however it still
352     took the full preloading time and on 1st program change the respective
353     instrument was completely reloaded again.
354 persson 2277 - fixed handling of rapid bank select and program change messages
355     sent to the same sampler channel (patch from the Open Octave

376 schoenebeck 1599
377 schoenebeck 1639 * packaging changes:
378     - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

396 schoenebeck 1639
397 schoenebeck 1601 * general changes:

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

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

421 schoenebeck 1800 - maximum voices and disk streams can now be altered at runtime
422 persson 1825 - fixed CPU feature detection on x86_64 (maybe fixes #108)
423 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
424     be switched on by command line option "--stacktrace" (the automatic
425     stacktrace mechanism seems to be broken on most systems at the moment)
426 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
427     a pointer to the launched InstrumentEditor object
428 schoenebeck 1876 - added optional 3rd party user data parameter for following
429     liblinuxsampler C++ API methods: InstrumentEditor::Main(),

438 schoenebeck 1601
439 schoenebeck 1599 * audio driver:
440     - removed the nonsense audio channel constraint (which was hard coded to
441     max. 100 audio channels) for most audio drivers
442 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
443     opposed to the LSCP specs
444 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
445     reflected the wrong value
446 persson 1644 - fixed a memory management bug in ASIO driver
447 persson 1748 - Makefile fix: JACK_CFLAGS wasn't used

449 persson 1748 jack_client_new
450 iliev 1829 - added (experimental) CoreAudio driver
451 persson 1888 - applied old fixes to the ASIO driver that were included in the
452     previous binary release but accidentally never committed to CVS
453     (fixes #117)
454 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
455     win64)
456 persson 1895 - VST: added support for sample rate and buffer size changes
457     - VST: close editor (Fantasia) when the VST is removed

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

485     to the instruments database
486 iliev 1727 - added support for handling lost files in the instruments database
487 iliev 1781 - Implemented option for adding instruments in separate directories
488     in the instruments database
489     (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
490 persson 1908 - work-around for missing fnmatch function on Windows to make
491     instrument database compilable
492 schoenebeck 1930 - added instrument database support on Windows
493     works with both standalone mode and VST plugin.
494     the instruments DB file is located in
495     %USERPROFILE%\.linuxsampler\instruments.db which allows different
496     databases for each windows user
497     if no DB is present it automatically creates the .linuxsampler subdir
498     and then creates an empty DB
499 persson 1943 - fixed recursive import, which was broken on Windows
500 iliev 1603
501 persson 1644 * Gigasampler format engine:
502     - fixed a memory leak that could happen when a channel was deleted
503     while notes were playing
504 persson 1646 - made it possible to load an instrument even if the audio thread
505     isn't running
506 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
507     enough for piano gigs with pedal noise samples
508 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
509     respective FX send MIDI controller was used
510 schoenebeck 1724 - added support for GM global device volume SysEx message
511 schoenebeck 1762 (can be selected at compile time to either apply globally to the
512     whole sampler [default] or only to the sampler channels that are
513     connected to the respective MIDI input port the SysEx message arrived
514     on)
515 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
516     sometimes wrongly killed in the same buffer, causing no sound to
517     be played
518 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
519     which is usally used to switch a part between chromatic sounds and
520     drumkit sounds (as opposed to their common default setting of MIDI
521     part 10 being a drumkit part and all other ones chromatic parts), in
522     LS however one can switch between the first 16 MIDI instrument maps
523     defined for the sampler
524 persson 1764 - made it possible to create multiple sample channels even if the
525     audio thread isn't running
526 persson 1844 - fixed crash when removing channel with active voices (#116)
527 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
528     un-cache the respective sample if it's really not used by any
529     sampler engine anymore
530     - re-cache samples in case they were changed by an instrument editor,
531     e.g. when a sample was added while playing (#82)
532 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
533     same time stamp as the voice's note-on event and occured both in the
534     same audio fragment cycle (fixes bug #112)
535 persson 1858 - added support for the "fine tune" and "pitch bend range"
536     instrument-level gig parameters
537     - fixed minor artifacts in pitch bend handling
538 schoenebeck 1860 - added support for GS Reset SysEx message
539 persson 1862 - allow gig files to use unlimited downward pitch shifting
540     - added a limit check for upward pitch shifting
541 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
542     note was silent
543 persson 1923 - fixed crash happening when a pitch bend event arrived at the
544     same time a new instrument was loading
545 persson 1644
546 schoenebeck 1687 * LSCP server:
547     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
548     react on MIDI data arriving on certain sampler channels (so far only
549     Note-On and Note-Off events are sent via this LSCP event)
550 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
551     react on MIDI data arriving on certain MIDI input devices (so far only
552     Note-On and Note-Off events are sent via this LSCP event)
553 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
554     SET DB_INSTRUMENT FILE_PATH
555 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
556     frontends to send MIDI messages to specific sampler channel
557     - added two additional fields to GET FILE INSTRUMENT INFO command -
558     KEY_BINDINGS and KEYSWITCH_BINDINGS
559 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
560     was incorrect
561 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
562 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
563     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
564     be triggered respectively
565     - added new LSCP command "SET STREAMS" to globally alter the maximum
566     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
567     which will be triggered respectively
568 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
569     a gigedit file dialog is opened)
570 iliev 1848 - close all connections when LSCPServer is deleted
571 iliev 1882 - hard close of all sockets on exit
572 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
573     driver
574 schoenebeck 1687
575 iliev 1761 * Bug fixes:
576     - fixed a crash which occurs when removing a sampler channel waiting
577     to start instrument loading after another channel
578 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
579     instrument loading in progress (bug #113)
580 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
581     instrument with PERSISTENT load mode
582 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
583     - fixed memory leaks when issuing the following LSCP commands:
584     GET AUDIO_OUTPUT_DRIVER INFO
585     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
586     GET MIDI_INPUT_DRIVER INFO
587     GET MIDI_INPUT_DRIVER_PARAMETER INFO
588     - fixed possible compilation error when sqlite is not present
589 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
590 iliev 1847 - fixed crash when changing the audio output device of a sampler
591     channel with loaded instrument and start playing notes
592 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
593 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
594     PowerPC, which probably could cause crashes on that platform
595 persson 1889 - fixed a memory management error which could cause a crash when a
596     plugin was unloaded
597 persson 1896 - bugfix: two private structs had the same name, which could cause
598     problems if the linker chose the wrong constructor
599 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
600     Windows
601 iliev 1761
602    
603 schoenebeck 1560 Version 0.5.1 (6 December 2007)
604 schoenebeck 1454
605     * packaging changes:
606     - added autoconf checks for pthread library
607     - added autoconf check for pthread bug found on certain NPTL-enabled
608     glibc versions (see Gentoo bug report #194076)
609 senoner 1502 - added autoconf checks for MS Windows
610 schoenebeck 1454
611 persson 1455 * general changes:
612     - bugfix: the thread used by an editor plugin didn't die when the
613     editor closed
614 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
615     out all the space. operator--() did not apply size_mask after
616     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
617     order to avoid problems with the _NonVolatileReader functions.
618     - bugfix: Stream.h: added a missing divide by BytesPerSample in
619     GetWriteSpace(). Since this function is currently only used in
620     the stream's qsort() compare function, it didn't trigger any
621     bugs.
622     - Resampler.h, Synthesizer.h: cubic interpolation now works in
623     24bit mode too. Faster method to read 24bit words on little
624     endian machines (x86): replaced 3 byte reads + shifts with a 1
625     unaligned 32bit read and shift
626     - experimental support for MS Windows (MIDI input via MME, AUDIO
627     output via ASIO)
628     - made handling of SIGINT signal (Ctrl-C) a bit more robust
629 iliev 1541 - support for monitoring the total number of active disk streams
630     (new LSCP commands: GET TOTAL_STREAM_COUNT,
631     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
632 persson 1455
633 senoner 1500 * AUDIO driver:
634 persson 1534 - added Windows ASIO low latency audio driver
635 senoner 1500
636 senoner 1485 * MIDI driver:
637 schoenebeck 1495 - added MME Windows MIDI driver
638 senoner 1485
639 schoenebeck 1471 * LSCP server:
640     - added support for Windows style path / filenames, however with
641     forward slash path separators instead of backslash
642     (i.e. "C:/foo/bar.gig")
643 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
644     apostrophes as well
645 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
646     "LIST FILE INSTRUMENTS <file>" and
647     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
648     about an arbitrary instrument file on the system where the sampler is
649     running on
650 schoenebeck 1471
651 schoenebeck 1424 Version 0.5.0 (15 October 2007)
652 schoenebeck 947
653 schoenebeck 1065 * packaging changes:
654 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
655     API header files anymore
656 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
657     the Doxygen API documentation (explicitly listed in Doxyfile.in)
658 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
659     capable to execute our autoconf environment, thus no need anymore
660     to maintain the compile time configuration file (osx/version.h) for
661     OSX manually (patch by Toshi Nagata)
662 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
663     parameters
664 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
665     C++ API header files, all implementation internal global definitions
666     are now in global_private.h
667     - atomic.h is not exposed to the C++ API anymore
668     - no need to include config.h anymore for using LS's API header files
669     - fixed warnings in API doc generation
670 schoenebeck 1065
671 schoenebeck 947 * general changes:
672     - replaced the old, confusing MIDI program change mechanism by a
673     flexible MIDI instrument mapper which allows to map arbitrary
674 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
675 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
676     loaded on the respective channel when such MIDI program change
677     messages arrive, beside that, each entry allows to define a life-time
678     strategy for the instrument, so the user can define whether the
679     instrument should i.e. be permanently loaded (to be able to switch
680     quickly among sounds) or i.e. loaded just on demand when the
681     respective program change arrives (to safe RAM space), as well as a
682     global volume factor for each entry, so the user can adjust the volume
683     dynamic of his mapped instrument collection without having to modify
684 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
685     MIDI instrument maps and assign each sampler channel individually
686     a certain map, so that i.e. separation of normal instruments and
687     drumkits is possible
688 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
689     MIDI instrument maps, MIDI instruments, FX sends, global volume.
690 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
691     due to a constant size RingBuffer FIFO which is now replaced by a
692     dynamic (unlimited) size std::list FIFO
693 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
694     output channels for being processed by external effect processors
695     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
696     controllers
697 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
698 iliev 1130 - Implemented new, improved notification system
699 schoenebeck 1149 - fixed compilation errors regarding OSX
700     (patch by Toshi Nagata)
701 iliev 1161 - implemented instruments database
702 iliev 1345 - added support for escape sequences to the instruments database
703 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
704     within the sampler's process (by using instrument editor plugins),
705     you'll notice the new "Registered instrument editors:" message on
706 schoenebeck 1407 startup, added a new LSCP command:
707     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
708 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
709     given sampler channel, the plugin path can be overridden at compile
710     time with ./configure --enable-plugin-dir=/some/dir
711 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
712     in the sampler's process to safely edit instruments while playing
713     without a crash (hopefully) by either suspending single regions
714     wherever possible or if unavoidable whole engine(s)
715 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
716     policy and priority on thread level, set a minimum stack size for
717     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
718     threads simply inherited properties of starting thread instead of
719     setting their own policy and priority
720 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
721     main process did not wait for the stack trace process to finish
722     its output
723 persson 1248 - fixed some minor memory leaks
724 schoenebeck 1259 - reenabled assembly features support, at the moment only for
725     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
726 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
727     register, to avoid relocations in the text segment at runtime)
728 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
729 schoenebeck 947
730     * MIDI driver:
731     - dispatch bank select (MSB and LSB) messages
732    
733 schoenebeck 1049 * audio driver:
734     - the ALSA audio output driver parameters now reflect the correct
735     parameter value ranges for the respective selected sound card
736     (patch by Till Wimmer, a bit fixed and extended)
737    
738 persson 951 * Gigasampler format engine:
739     - if a filter is used and EG2 finishes before EG1, let the voice
740     die when EG2 has finished (this fixes a problem with clicks and
741     voice starvation for some gigs)
742 persson 1038 - playback is no longer disabled during instrument loading
743     - all notes playing on a channel that changes its instrument keep
744     playing with the old instrument until they get a note off
745     command
746 persson 1039 - EG fix: a release value of zero could cause noises or crash
747 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
748 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
749     above max sustain level, which means that there is a decay phase
750     even if sustain is 100%
751 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
752     noises or crashes
753 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
754 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
755     supplied to the configure script (fixes #46)
756 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
757     instead of a fix value
758 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
759     127 (solo mode) only kill voices if the respective mode really
760     changed
761 persson 951
762 schoenebeck 1244 * LSCP server:
763     - fixed compile time error for old Bison versions
764     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
765 schoenebeck 1245 - parser now supports extended ASCII character set
766     (up to ASCII code 255, i.e. includes now umlauts and accents)
767     - filename arguments in LSCP commands now allow to use escape
768     sequences, that is directly literal as one of: \', \", \\, \n, \r,
769     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
770     code value like \xf2) (fixes bug #24)
771 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
772     least one of their text-based parameters (i.e. name, description):
773     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
774     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
775     "SET DB_INSTRUMENT_DIRECTORY NAME",
776     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
777     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
778     "FIND DB_INSTRUMENT_DIRECTORIES"
779 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
780     occured, the unexpected character and the actually expected, possible
781     character(s), the latter only if less than 5 possibilities)
782 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
783     settings
784 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
785     of strings were treated as being one string containing commas
786     (fixes #57)
787 schoenebeck 1244
788 iliev 959 * Bug fixes:
789     - fixed crash occurring on certain LSCP scripts (Bug 39)
790 persson 1038 - another thread safety fix for lscp "load engine" and "set
791     channel audio output device"
792 iliev 1283 - fixed a crash which occurs when reassigning the same engine
793     on a sampler channel with connected MIDI device
794 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
795     device connected to a sampler channel to number less then or equal
796     to the index of the port to which the sampler channel is connected.
797 iliev 1296 - The previous bindings were not been disconnected when altering
798     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
799     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
800 iliev 1297 - The active stream/voice count statistic was incorrect.
801 iliev 1298 - notification events were not been sent for some sampler
802     channel changes
803 iliev 1305 - added default min and max values to restrict the number of allowed
804     audio output channels and MIDI input ports
805 iliev 1306 - the connection to the PCM interface is now closed when destroying
806     an audio output device
807 schoenebeck 1332 - files with slash in their path or filename could not be loaded
808 iliev 959
809 schoenebeck 1221 * test cases:
810     - updated and fixed (haven't been touched in a while)
811    
812 schoenebeck 937 Version 0.4.0 (24 November 2006)
813 persson 696
814 schoenebeck 697 * packaging changes:
815 capela 868 - changed deprecated copyright attribute to license; added ldconfig
816     to post-(un)install steps; added devel package for liblinuxsampler;
817     to linuxsampler.spec (RPM)
818 schoenebeck 697 - install necessary development header files for allowing 3rd party
819     applications to link against liblinuxsampler
820     - liblinuxsampler's API documentation can be generated with 'make docs'
821     (Doxygen required)
822 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
823     implementation (currently either an integer math solution or a
824     di-harmonic approximation), automatic detection can be overriden
825     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
826     configure script argument though (mandatory for cross-compilation)
827 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
828     provided some on his own (as CXXFLAGS)
829 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
830     messages
831 schoenebeck 852 - added compile time options to allow disabling the various audio and
832     MIDI drivers
833 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
834     (patch by Ebrahim Mayat)
835 schoenebeck 697
836 persson 696 * Gigasampler format engine:
837 schoenebeck 738 - extensive synthesis optimization
838     (reimplementation of EGs and LFO(s), removed synthesis parameter
839     prerendering and the synthesis parameter matrix in general, splitting
840     each audio fragment into subfragments now where each subfragment uses
841 persson 830 constant pitch and filter coefficients. The volume coefficient is
842     linearly interpolated inside a subfragment, unless
843     --disable-interpolate-volume is set.)
844 persson 696 - fine tuning of the EG modulation parameters
845 persson 729 - improved filter cutoff calculation by adding support for the
846     following gig parameters: Cutoff freq (used when no cutoff
847     controller is defined), Control invert, Minimum cutoff, Velocity
848 persson 791 curve and Velocity range. The keyboard tracking now scales
849     cutoff frequency instead of resonance.
850 persson 877 - added support for gig parameter Resonance.
851 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
852 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
853     which can be overridden with --enable-global-attenuation
854 persson 783 - EG fixes: made the length of "attack hold" stage more
855     accurate. Release stage can now start before attack stage
856 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
857     time now has a minimal value to prevent clicks.
858 persson 799 - fixed pitch changes larger than one octave
859 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
860     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
861     all modes can be altered via standard GM messages, that is CC5 for
862     altering portamento time, CC65 for enabling / disabling portamento
863     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
864 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
865     parameter) and crossfade
866 persson 831 - added support for the "attenuation controller threshold" gig
867     parameter
868 persson 832 - added smoothing of volume changes caused by control change
869     messages
870 persson 865 - sample loop parameters are now taken from the DimensionRegion
871     instead of the wave chunk
872     - fixed keyswitching for v3 gigs with a number of keyswitch splits
873     not equal to a power of two
874 persson 877 - reimplementation of the filter algorithm. The new filter is more
875     accurate and supports all gig filter types, including bandreject
876     and lowpass turbo.
877 persson 903 - real support for 24 bit samples - samples are not truncated to
878     16 bits anymore
879     - support for aftertouch (channel pressure, not polyphonic
880     aftertouch)
881 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
882     amplifying from 0)
883 persson 696
884 schoenebeck 711 * LSCP server:
885     - fixed application exit on broken pipe error (fixes bug #20)
886 iliev 793 - fixed the notification messages delay due to lack of
887     network activity (fixes bug #26)
888 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
889     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
890 schoenebeck 711
891 schoenebeck 838 * audio driver:
892     - added aRts audio output driver (by no means RT safe)
893    
894 schoenebeck 775 * MIDI driver:
895     - fixed legacy sysex code which caused dispatching of MIDI SysEx
896     messages several times instead of once
897 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
898     for events (i.e. for offline rendering based MIDI drivers)
899 persson 922 - added checks for bad MIDI data
900 schoenebeck 775
901 schoenebeck 900 * linuxsampler application:
902     - show available sampler engine types on startup
903    
904 schoenebeck 705 * general changes:
905     - support for muting sampler channels and solo mode of the same, two new
906     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
907     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
908     introduced for this, the behavior is the same like on a mixer console
909 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
910     --enable-process-muted-channels which can be used to enable the
911     processing of muted channels.
912 iliev 777 - support for sostenuto pedal
913 iliev 779 - support for monitoring the total number of active voices
914 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
915     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
916 persson 835 - fixed some memory management errors
917 persson 841 - fixed some concurrency problems that could lead to crashes when
918     LSCP commands were executed
919 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
920     sampler channel (fixes bug #36)
921 schoenebeck 705
922 schoenebeck 692 Version 0.3.3 (15 July 2005)
923 schoenebeck 686
924     * packaging changes:
925     - fixed compilation with gcc 4.0
926    
927 schoenebeck 687 * Gigasampler format engine:
928     - LFO preprocessing was performed even though the respective LFO was
929     disabled by the instrument patch (minor efficiency fix)
930 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
931     for volume ramp downs in the same fragment (needed for current voice
932     stealing implementation) then simply inform the user with a warning
933     about possible click sounds and reduce the volume ramp down
934     appropriately instead of cancelling the audio device connection
935 schoenebeck 687
936 schoenebeck 677 Version 0.3.2 (24 June 2005)
937 schoenebeck 609
938     * packaging changes:
939     - updated autotools build files to compile on OS X
940     (conditional compilation of CoreMIDI and MidiShare drivers)
941 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
942     './configure --disable-asm' (definitely not recommended)
943 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
944     - require automake (>= 1.5) for 'make -f Makefile.cvs'
945     (due to 'dist-bzip2' automake option)
946 schoenebeck 649
947     * Gigasampler format engine:
948     - support for the gig parameters for "release velocity response" curves
949     - fine tuning of the EGADSR envelope
950     - volume of release triggered samples now depends on note-on velocity,
951     note length and gig parameter "release trigger decay" instead of
952     note-off velocity.
953 schoenebeck 663 - revised voice stealing
954     (fixes crash and endless loop caused by voice stealing)
955 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
956 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
957     instead of when the respective voice is actually launched
958     (fixes undefined behavior if stolen voices belonged to a key group -
959     this case was followed by a "killed voice survived" error message)
960 schoenebeck 669 - fixed minor issue with null/silence samples
961     (those stole voices even though they don't need a voice at all which
962     resulted in "voice stealing didn't work out" messages)
963 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
964     instrument or audio output device change
965 schoenebeck 654
966 schoenebeck 620 * LSCP server:
967 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
968 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
969 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
970 schoenebeck 609
971 schoenebeck 668 * linuxsampler application:
972     - added command line parameters --lscp-addr and --lscp-port to override
973     default IP address and port of LSCP server
974    
975 schoenebeck 579 Version 0.3.1 (24 May 2005)
976    
977     * initial release
