* DSSI bugfix: it wasn't possible to change engine type. The MIDI port
  and audio channel routing for DSSI plugins are now visible.

1 schoenebeck 1993 Version CVS HEAD (?)
2    
3 capela 2174 * plugin changes:
4 schoenebeck 2304 - LV2 "state" extension support (patch by David Robillard)
5 capela 2174
6 persson 2086 * packaging changes:
7     - fixed building with newer MinGW-w64
8 persson 2183 - Mac OS X: support the new dir for Core Audio SDK
9     - Mac OS X: fixed building outside source directory
10     - made sure all source files for hostplugins are included when
11     doing "make dist"
12     - removed empty directories left from the cvs to svn migration
13 persson 2185 - fixed compilation with gcc 4.6.1
14 persson 2203 - another "make dist" fix, for the LV2 plugin
15 persson 2185 - made --enable-pthread-testcancel default on Mac OS X
16 persson 2197 - minor Makefile fix for building lscpparser when build and source
17     directories are separate
18 persson 2203 - Mac OS X: made it possible to specify plugin installation dir to
19     configure
20 persson 2208 - Mac OS X: Makefile fix for the install-strip target
21 persson 2335 - fixed compilation with gcc 4.7
22 persson 2343 - fixed configure script error with old autoconf versions
23     - lsatomic.h: use gcc provided atomic functions if building with

25 persson 2086
26     * 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)

49 iliev 2296 - experimental support for per voice equalization
50 iliev 2306 - added command line option --exec-after-init
51 schoenebeck 2330 - Introduced new C++ API method:
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 iliev 2012
58 persson 2043 * Gigasampler format engine:

351 schoenebeck 1599
352 schoenebeck 1639 * packaging changes:
353     - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
354     causing e.g. the libgig test to fail when
355     "./configure --disable-jack-driver" was used
356     (patch by Alexis Ballier)

364 persson 1897 - Windows: look for editor plugins and Fantasia using base
365 schoenebeck 1928 directory of liblinuxsampler dll (look in the same directory and one
366     directory above)
367 persson 1899 - configure script fix: removed unconditional use of SSE
368 persson 1923 - fixed building with sqlite installed in a non-standard directory

371 schoenebeck 1639
372 schoenebeck 1601 * general changes:
373     - bugfix: on some POSIX systems instrument editor plugins refused to
374     load as we used a non-portable Linux specific struct field
375     (fixes bug #70, patch by Ronald Baljeu)
376 schoenebeck 1602 - fixed endless loop which occured when loading an instrument editor
377     plugin DLL on Windows systems failed
378 persson 1644 - fixed memory leaks that occurred when liblinuxsampler was unloaded
379     - optimized the SynchronizedConfig class so it doesn't wait
380     unnecessarily long after an update
381 schoenebeck 1653 - added support for notifying instrument editors on note-on / note-off
382     events (e.g. to highlight the pressed keys on the virtual keyboard
383     of gigedit)

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

388     implementation, which is usually faster)
389 persson 1748 - fixes for audio drivers with varying buffer sizes
390 persson 1777 - experimental support for running LinuxSampler as a DSSI, LV2 and
391     VST plugin

395     multi-core and multi-cpu systems
396 schoenebeck 1800 - maximum voices and disk streams can now be altered at runtime
397 persson 1825 - fixed CPU feature detection on x86_64 (maybe fixes #108)
398 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
399     be switched on by command line option "--stacktrace" (the automatic
400     stacktrace mechanism seems to be broken on most systems at the moment)
401 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
402     a pointer to the launched InstrumentEditor object
403 schoenebeck 1876 - added optional 3rd party user data parameter for following
404     liblinuxsampler C++ API methods: InstrumentEditor::Main(),
405     InstrumentEditor::Launch(),

407 persson 1887 - theoretical fix: made SynchronizedConfig follow C++0x memory
408     model more strictly
409 persson 1895 - fixes for using large audio device buffers
410 persson 1951 - Windows: add the installation directory to the DLL search path

412     gigedit on systems with other GTK versions installed)
413 schoenebeck 1601
414 schoenebeck 1599 * audio driver:
415     - removed the nonsense audio channel constraint (which was hard coded to
416     max. 100 audio channels) for most audio drivers
417 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
418     opposed to the LSCP specs
419 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
420     reflected the wrong value
421 persson 1644 - fixed a memory management bug in ASIO driver
422 persson 1748 - Makefile fix: JACK_CFLAGS wasn't used
423 persson 1777 - JACK: use jack_client_open instead of the deprecated
424 persson 1748 jack_client_new
425 iliev 1829 - added (experimental) CoreAudio driver
426 persson 1888 - applied old fixes to the ASIO driver that were included in the
427     previous binary release but accidentally never committed to CVS
428     (fixes #117)
429 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
430     win64)
431 persson 1895 - VST: added support for sample rate and buffer size changes
432     - VST: close editor (Fantasia) when the VST is removed

437     stereo
438 persson 1922 - added channel routing, fxsends and midi maps to the settings
439     stored in the plugin state
440 schoenebeck 1930 - performance optimization of AudioChannel::MixTo() and
441     AudioChannel::CopyTo() methods using GCC vector exensions
442     (if available)
443 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
444     exception when getting parameters from a disconnected device
445 schoenebeck 1599
446 persson 1651 * MIDI driver:
447     - added JACK MIDI driver
448 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
449     want to (mis)use it for some purpose ("fixed" in all current MIDI
450     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
451 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
452 persson 1887 CoreMidi or AU
453 persson 1889 - fixed mingw-w64 compilation error in MME driver
454 persson 1924 - made program change handling in MIDI thread real-time safe by
455     moving the logic to a non-RT thread
456 persson 1951 - fixed minor memory leak in ALSA driver
457 persson 1651
458 schoenebeck 1604 * instruments database:
459 iliev 1603 - avoid time consuming samples scanning when adding instruments
460     to the instruments database
461 iliev 1727 - added support for handling lost files in the instruments database
462 iliev 1781 - Implemented option for adding instruments in separate directories
463     in the instruments database
464     (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
465 persson 1908 - work-around for missing fnmatch function on Windows to make
466     instrument database compilable
467 schoenebeck 1930 - added instrument database support on Windows
468     works with both standalone mode and VST plugin.
469     the instruments DB file is located in
470     %USERPROFILE%\.linuxsampler\instruments.db which allows different
471     databases for each windows user
472     if no DB is present it automatically creates the .linuxsampler subdir
473     and then creates an empty DB
474 persson 1943 - fixed recursive import, which was broken on Windows
475 iliev 1603
476 persson 1644 * Gigasampler format engine:
477     - fixed a memory leak that could happen when a channel was deleted
478     while notes were playing
479 persson 1646 - made it possible to load an instrument even if the audio thread
480     isn't running
481 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
482     enough for piano gigs with pedal noise samples
483 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
484     respective FX send MIDI controller was used
485 schoenebeck 1724 - added support for GM global device volume SysEx message
486 schoenebeck 1762 (can be selected at compile time to either apply globally to the
487     whole sampler [default] or only to the sampler channels that are
488     connected to the respective MIDI input port the SysEx message arrived
489     on)
490 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
491     sometimes wrongly killed in the same buffer, causing no sound to
492     be played
493 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
494     which is usally used to switch a part between chromatic sounds and
495     drumkit sounds (as opposed to their common default setting of MIDI
496     part 10 being a drumkit part and all other ones chromatic parts), in
497     LS however one can switch between the first 16 MIDI instrument maps
498     defined for the sampler
499 persson 1764 - made it possible to create multiple sample channels even if the
500     audio thread isn't running
501 persson 1844 - fixed crash when removing channel with active voices (#116)
502 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
503     un-cache the respective sample if it's really not used by any
504     sampler engine anymore
505     - re-cache samples in case they were changed by an instrument editor,
506     e.g. when a sample was added while playing (#82)
507 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
508     same time stamp as the voice's note-on event and occured both in the
509     same audio fragment cycle (fixes bug #112)
510 persson 1858 - added support for the "fine tune" and "pitch bend range"
511     instrument-level gig parameters
512     - fixed minor artifacts in pitch bend handling
513 schoenebeck 1860 - added support for GS Reset SysEx message
514 persson 1862 - allow gig files to use unlimited downward pitch shifting
515     - added a limit check for upward pitch shifting
516 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
517     note was silent
518 persson 1923 - fixed crash happening when a pitch bend event arrived at the
519     same time a new instrument was loading
520 persson 1644
521 schoenebeck 1687 * LSCP server:
522     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
523     react on MIDI data arriving on certain sampler channels (so far only
524     Note-On and Note-Off events are sent via this LSCP event)
525 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
526     react on MIDI data arriving on certain MIDI input devices (so far only
527     Note-On and Note-Off events are sent via this LSCP event)
528 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
529     SET DB_INSTRUMENT FILE_PATH
530 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
531     frontends to send MIDI messages to specific sampler channel
532     - added two additional fields to GET FILE INSTRUMENT INFO command -
533     KEY_BINDINGS and KEYSWITCH_BINDINGS
534 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
535     was incorrect
536 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
537 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
538     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
539     be triggered respectively
540     - added new LSCP command "SET STREAMS" to globally alter the maximum
541     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
542     which will be triggered respectively
543 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
544     a gigedit file dialog is opened)
545 iliev 1848 - close all connections when LSCPServer is deleted
546 iliev 1882 - hard close of all sockets on exit
547 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
548     driver
549 schoenebeck 1687
550 iliev 1761 * Bug fixes:
551     - fixed a crash which occurs when removing a sampler channel waiting
552     to start instrument loading after another channel
553 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
554     instrument loading in progress (bug #113)
555 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
556     instrument with PERSISTENT load mode
557 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
558     - fixed memory leaks when issuing the following LSCP commands:
559     GET AUDIO_OUTPUT_DRIVER INFO
560     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
561     GET MIDI_INPUT_DRIVER INFO
562     GET MIDI_INPUT_DRIVER_PARAMETER INFO
563     - fixed possible compilation error when sqlite is not present
564 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
565 iliev 1847 - fixed crash when changing the audio output device of a sampler
566     channel with loaded instrument and start playing notes
567 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
568 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
569     PowerPC, which probably could cause crashes on that platform
570 persson 1889 - fixed a memory management error which could cause a crash when a
571     plugin was unloaded
572 persson 1896 - bugfix: two private structs had the same name, which could cause
573     problems if the linker chose the wrong constructor
574 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
575     Windows
576 iliev 1761
577    
578 schoenebeck 1560 Version 0.5.1 (6 December 2007)
579 schoenebeck 1454
580     * packaging changes:
581     - added autoconf checks for pthread library
582     - added autoconf check for pthread bug found on certain NPTL-enabled
583     glibc versions (see Gentoo bug report #194076)
584 senoner 1502 - added autoconf checks for MS Windows
585 schoenebeck 1454
586 persson 1455 * general changes:
587     - bugfix: the thread used by an editor plugin didn't die when the
588     editor closed
589 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
590     out all the space. operator--() did not apply size_mask after
591     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
592     order to avoid problems with the _NonVolatileReader functions.
593     - bugfix: Stream.h: added a missing divide by BytesPerSample in
594     GetWriteSpace(). Since this function is currently only used in
595     the stream's qsort() compare function, it didn't trigger any
596     bugs.
597     - Resampler.h, Synthesizer.h: cubic interpolation now works in
598     24bit mode too. Faster method to read 24bit words on little
599     endian machines (x86): replaced 3 byte reads + shifts with a 1
600     unaligned 32bit read and shift
601     - experimental support for MS Windows (MIDI input via MME, AUDIO
602     output via ASIO)
603     - made handling of SIGINT signal (Ctrl-C) a bit more robust
604 iliev 1541 - support for monitoring the total number of active disk streams
605     (new LSCP commands: GET TOTAL_STREAM_COUNT,
606     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
607 persson 1455
608 senoner 1500 * AUDIO driver:
609 persson 1534 - added Windows ASIO low latency audio driver
610 senoner 1500
611 senoner 1485 * MIDI driver:
612 schoenebeck 1495 - added MME Windows MIDI driver
613 senoner 1485
614 schoenebeck 1471 * LSCP server:
615     - added support for Windows style path / filenames, however with
616     forward slash path separators instead of backslash
617     (i.e. "C:/foo/bar.gig")
618 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
619     apostrophes as well
620 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
621     "LIST FILE INSTRUMENTS <file>" and
622     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
623     about an arbitrary instrument file on the system where the sampler is
624     running on
625 schoenebeck 1471
626 schoenebeck 1424 Version 0.5.0 (15 October 2007)
627 schoenebeck 947
628 schoenebeck 1065 * packaging changes:
629 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
630     API header files anymore
631 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
632     the Doxygen API documentation (explicitly listed in Doxyfile.in)
633 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
634     capable to execute our autoconf environment, thus no need anymore
635     to maintain the compile time configuration file (osx/version.h) for
636     OSX manually (patch by Toshi Nagata)
637 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
638     parameters
639 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
640     C++ API header files, all implementation internal global definitions
641     are now in global_private.h
642     - atomic.h is not exposed to the C++ API anymore
643     - no need to include config.h anymore for using LS's API header files
644     - fixed warnings in API doc generation
645 schoenebeck 1065
646 schoenebeck 947 * general changes:
647     - replaced the old, confusing MIDI program change mechanism by a
648     flexible MIDI instrument mapper which allows to map arbitrary
649 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
650 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
651     loaded on the respective channel when such MIDI program change
652     messages arrive, beside that, each entry allows to define a life-time
653     strategy for the instrument, so the user can define whether the
654     instrument should i.e. be permanently loaded (to be able to switch
655     quickly among sounds) or i.e. loaded just on demand when the
656     respective program change arrives (to safe RAM space), as well as a
657     global volume factor for each entry, so the user can adjust the volume
658     dynamic of his mapped instrument collection without having to modify
659 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
660     MIDI instrument maps and assign each sampler channel individually
661     a certain map, so that i.e. separation of normal instruments and
662     drumkits is possible
663 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
664     MIDI instrument maps, MIDI instruments, FX sends, global volume.
665 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
666     due to a constant size RingBuffer FIFO which is now replaced by a
667     dynamic (unlimited) size std::list FIFO
668 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
669     output channels for being processed by external effect processors
670     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
671     controllers
672 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
673 iliev 1130 - Implemented new, improved notification system
674 schoenebeck 1149 - fixed compilation errors regarding OSX
675     (patch by Toshi Nagata)
676 iliev 1161 - implemented instruments database
677 iliev 1345 - added support for escape sequences to the instruments database
678 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
679     within the sampler's process (by using instrument editor plugins),
680     you'll notice the new "Registered instrument editors:" message on
681 schoenebeck 1407 startup, added a new LSCP command:
682     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
683 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
684     given sampler channel, the plugin path can be overridden at compile
685     time with ./configure --enable-plugin-dir=/some/dir
686 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
687     in the sampler's process to safely edit instruments while playing
688     without a crash (hopefully) by either suspending single regions
689     wherever possible or if unavoidable whole engine(s)
690 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
691     policy and priority on thread level, set a minimum stack size for
692     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
693     threads simply inherited properties of starting thread instead of
694     setting their own policy and priority
695 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
696     main process did not wait for the stack trace process to finish
697     its output
698 persson 1248 - fixed some minor memory leaks
699 schoenebeck 1259 - reenabled assembly features support, at the moment only for
700     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
701 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
702     register, to avoid relocations in the text segment at runtime)
703 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
704 schoenebeck 947
705     * MIDI driver:
706     - dispatch bank select (MSB and LSB) messages
707    
708 schoenebeck 1049 * audio driver:
709     - the ALSA audio output driver parameters now reflect the correct
710     parameter value ranges for the respective selected sound card
711     (patch by Till Wimmer, a bit fixed and extended)
712    
713 persson 951 * Gigasampler format engine:
714     - if a filter is used and EG2 finishes before EG1, let the voice
715     die when EG2 has finished (this fixes a problem with clicks and
716     voice starvation for some gigs)
717 persson 1038 - playback is no longer disabled during instrument loading
718     - all notes playing on a channel that changes its instrument keep
719     playing with the old instrument until they get a note off
720     command
721 persson 1039 - EG fix: a release value of zero could cause noises or crash
722 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
723 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
724     above max sustain level, which means that there is a decay phase
725     even if sustain is 100%
726 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
727     noises or crashes
728 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
729 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
730     supplied to the configure script (fixes #46)
731 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
732     instead of a fix value
733 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
734     127 (solo mode) only kill voices if the respective mode really
735     changed
736 persson 951
737 schoenebeck 1244 * LSCP server:
738     - fixed compile time error for old Bison versions
739     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
740 schoenebeck 1245 - parser now supports extended ASCII character set
741     (up to ASCII code 255, i.e. includes now umlauts and accents)
742     - filename arguments in LSCP commands now allow to use escape
743     sequences, that is directly literal as one of: \', \", \\, \n, \r,
744     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
745     code value like \xf2) (fixes bug #24)
746 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
747     least one of their text-based parameters (i.e. name, description):
748     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
749     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
750     "SET DB_INSTRUMENT_DIRECTORY NAME",
751     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
752     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
753     "FIND DB_INSTRUMENT_DIRECTORIES"
754 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
755     occured, the unexpected character and the actually expected, possible
756     character(s), the latter only if less than 5 possibilities)
757 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
758     settings
759 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
760     of strings were treated as being one string containing commas
761     (fixes #57)
762 schoenebeck 1244
763 iliev 959 * Bug fixes:
764     - fixed crash occurring on certain LSCP scripts (Bug 39)
765 persson 1038 - another thread safety fix for lscp "load engine" and "set
766     channel audio output device"
767 iliev 1283 - fixed a crash which occurs when reassigning the same engine
768     on a sampler channel with connected MIDI device
769 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
770     device connected to a sampler channel to number less then or equal
771     to the index of the port to which the sampler channel is connected.
772 iliev 1296 - The previous bindings were not been disconnected when altering
773     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
774     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
775 iliev 1297 - The active stream/voice count statistic was incorrect.
776 iliev 1298 - notification events were not been sent for some sampler
777     channel changes
778 iliev 1305 - added default min and max values to restrict the number of allowed
779     audio output channels and MIDI input ports
780 iliev 1306 - the connection to the PCM interface is now closed when destroying
781     an audio output device
782 schoenebeck 1332 - files with slash in their path or filename could not be loaded
783 iliev 959
784 schoenebeck 1221 * test cases:
785     - updated and fixed (haven't been touched in a while)
786    
787 schoenebeck 937 Version 0.4.0 (24 November 2006)
788 persson 696
789 schoenebeck 697 * packaging changes:
790 capela 868 - changed deprecated copyright attribute to license; added ldconfig
791     to post-(un)install steps; added devel package for liblinuxsampler;
792     to linuxsampler.spec (RPM)
793 schoenebeck 697 - install necessary development header files for allowing 3rd party
794     applications to link against liblinuxsampler
795     - liblinuxsampler's API documentation can be generated with 'make docs'
796     (Doxygen required)
797 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
798     implementation (currently either an integer math solution or a
799     di-harmonic approximation), automatic detection can be overriden
800     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
801     configure script argument though (mandatory for cross-compilation)
802 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
803     provided some on his own (as CXXFLAGS)
804 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
805     messages
806 schoenebeck 852 - added compile time options to allow disabling the various audio and
807     MIDI drivers
808 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
809     (patch by Ebrahim Mayat)
810 schoenebeck 697
811 persson 696 * Gigasampler format engine:
812 schoenebeck 738 - extensive synthesis optimization
813     (reimplementation of EGs and LFO(s), removed synthesis parameter
814     prerendering and the synthesis parameter matrix in general, splitting
815     each audio fragment into subfragments now where each subfragment uses
816 persson 830 constant pitch and filter coefficients. The volume coefficient is
817     linearly interpolated inside a subfragment, unless
818     --disable-interpolate-volume is set.)
819 persson 696 - fine tuning of the EG modulation parameters
820 persson 729 - improved filter cutoff calculation by adding support for the
821     following gig parameters: Cutoff freq (used when no cutoff
822     controller is defined), Control invert, Minimum cutoff, Velocity
823 persson 791 curve and Velocity range. The keyboard tracking now scales
824     cutoff frequency instead of resonance.
825 persson 877 - added support for gig parameter Resonance.
826 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
827 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
828     which can be overridden with --enable-global-attenuation
829 persson 783 - EG fixes: made the length of "attack hold" stage more
830     accurate. Release stage can now start before attack stage
831 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
832     time now has a minimal value to prevent clicks.
833 persson 799 - fixed pitch changes larger than one octave
834 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
835     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
836     all modes can be altered via standard GM messages, that is CC5 for
837     altering portamento time, CC65 for enabling / disabling portamento
838     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
839 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
840     parameter) and crossfade
841 persson 831 - added support for the "attenuation controller threshold" gig
842     parameter
843 persson 832 - added smoothing of volume changes caused by control change
844     messages
845 persson 865 - sample loop parameters are now taken from the DimensionRegion
846     instead of the wave chunk
847     - fixed keyswitching for v3 gigs with a number of keyswitch splits
848     not equal to a power of two
849 persson 877 - reimplementation of the filter algorithm. The new filter is more
850     accurate and supports all gig filter types, including bandreject
851     and lowpass turbo.
852 persson 903 - real support for 24 bit samples - samples are not truncated to
853     16 bits anymore
854     - support for aftertouch (channel pressure, not polyphonic
855     aftertouch)
856 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
857     amplifying from 0)
858 persson 696
859 schoenebeck 711 * LSCP server:
860     - fixed application exit on broken pipe error (fixes bug #20)
861 iliev 793 - fixed the notification messages delay due to lack of
862     network activity (fixes bug #26)
863 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
864     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
865 schoenebeck 711
866 schoenebeck 838 * audio driver:
867     - added aRts audio output driver (by no means RT safe)
868    
869 schoenebeck 775 * MIDI driver:
870     - fixed legacy sysex code which caused dispatching of MIDI SysEx
871     messages several times instead of once
872 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
873     for events (i.e. for offline rendering based MIDI drivers)
874 persson 922 - added checks for bad MIDI data
875 schoenebeck 775
876 schoenebeck 900 * linuxsampler application:
877     - show available sampler engine types on startup
878    
879 schoenebeck 705 * general changes:
880     - support for muting sampler channels and solo mode of the same, two new
881     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
882     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
883     introduced for this, the behavior is the same like on a mixer console
884 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
885     --enable-process-muted-channels which can be used to enable the
886     processing of muted channels.
887 iliev 777 - support for sostenuto pedal
888 iliev 779 - support for monitoring the total number of active voices
889 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
890     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
891 persson 835 - fixed some memory management errors
892 persson 841 - fixed some concurrency problems that could lead to crashes when
893     LSCP commands were executed
894 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
895     sampler channel (fixes bug #36)
896 schoenebeck 705
897 schoenebeck 692 Version 0.3.3 (15 July 2005)
898 schoenebeck 686
899     * packaging changes:
900     - fixed compilation with gcc 4.0
901    
902 schoenebeck 687 * Gigasampler format engine:
903     - LFO preprocessing was performed even though the respective LFO was
904     disabled by the instrument patch (minor efficiency fix)
905 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
906     for volume ramp downs in the same fragment (needed for current voice
907     stealing implementation) then simply inform the user with a warning
908     about possible click sounds and reduce the volume ramp down
909     appropriately instead of cancelling the audio device connection
910 schoenebeck 687
911 schoenebeck 677 Version 0.3.2 (24 June 2005)
912 schoenebeck 609
913     * packaging changes:
914     - updated autotools build files to compile on OS X
915     (conditional compilation of CoreMIDI and MidiShare drivers)
916 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
917     './configure --disable-asm' (definitely not recommended)
918 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
919     - require automake (>= 1.5) for 'make -f Makefile.cvs'
920     (due to 'dist-bzip2' automake option)
921 schoenebeck 649
922     * Gigasampler format engine:
923     - support for the gig parameters for "release velocity response" curves
924     - fine tuning of the EGADSR envelope
925     - volume of release triggered samples now depends on note-on velocity,
926     note length and gig parameter "release trigger decay" instead of
927     note-off velocity.
928 schoenebeck 663 - revised voice stealing
929     (fixes crash and endless loop caused by voice stealing)
930 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
931 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
932     instead of when the respective voice is actually launched
933     (fixes undefined behavior if stolen voices belonged to a key group -
934     this case was followed by a "killed voice survived" error message)
935 schoenebeck 669 - fixed minor issue with null/silence samples
936     (those stole voices even though they don't need a voice at all which
937     resulted in "voice stealing didn't work out" messages)
938 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
939     instrument or audio output device change
940 schoenebeck 654
941 schoenebeck 620 * LSCP server:
942 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
943 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
944 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
945 schoenebeck 609
946 schoenebeck 668 * linuxsampler application:
947     - added command line parameters --lscp-addr and --lscp-port to override
948     default IP address and port of LSCP server
949    
950 schoenebeck 579 Version 0.3.1 (24 May 2005)
951    
952     * initial release
