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

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 schoenebeck 2375 - Added new C++ API method Sampler::GetGlobalMaxVoices().

284     - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
285     the driver will automatically connect to other CoreMIDI clients' ports
286     (e.g. external MIDI devices being attached to the Mac)
287 schoenebeck 1993

332 schoenebeck 2123 channel to a different engine type
333 persson 2127 - fixed crash when deleting a sampler channel or changing engine
334     type while an instrument load was in progress
335 persson 2162 - bugfix: playing a note while changing the instrument could cause
336     a crash, or give "Handing back unknown region" error messages
337 persson 2165 - bugfix: calling SET VOICES (which Fantasia does on start and
338     refresh) could cause instruments to be unloaded
339 persson 2183 - Mac OS X: fixed name collision of enum in EffectControl and
340     wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
341 persson 2185 - Mac OS X: fixed hanging threads
342 persson 2187 - Windows: disabled the previous thread fix on non-Mac systems, as
343     it caused hanging threads on Windows
344 iliev 2201 - Fixed possible crashes due to corrupted MIDI/audio device list
345     after MIDI/audio device creation failure
346 schoenebeck 2275 - When creating MIDI instrument map entries with "PERSISTENT" type, the
347     instruments were uselessly precached with zero samples, however it still
348     took the full preloading time and on 1st program change the respective
349     instrument was completely reloaded again.
350 persson 2277 - fixed handling of rapid bank select and program change messages
351     sent to the same sampler channel (patch from the Open Octave

372 schoenebeck 1599
373 schoenebeck 1639 * packaging changes:
374     - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

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

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

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

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

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

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

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