* Various "const" and "restrict" optimizations.

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
45     (as suggested by Alex Stone)

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().
56     - Added new C++ API method Sampler::GetGlobalMaxStreams().

285     - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
286     the driver will automatically connect to other CoreMIDI clients' ports
287     (e.g. external MIDI devices being attached to the Mac)
288 schoenebeck 1993
289 persson 2175 * audio driver:

337     a crash, or give "Handing back unknown region" error messages
338 persson 2165 - bugfix: calling SET VOICES (which Fantasia does on start and
339     refresh) could cause instruments to be unloaded

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

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

393 schoenebeck 1639
394 schoenebeck 1601 * general changes:

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

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

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

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

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

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

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