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

12 persson 2185 - made --enable-pthread-testcancel default on Mac OS X
13 persson 2197 - minor Makefile fix for building lscpparser when build and source
14     directories are separate
15 persson 2203 - Mac OS X: made it possible to specify plugin installation dir to
16     configure

25 persson 2365
26 persson 2086 * general changes:
27 iliev 2012 - Refactoring: moved the independent code from
28     the Gigasampler format engine to base classes
29 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
30     respective profiling code is currently broken
31 schoenebeck 2053 - Introduced support for optional environment variable
32     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
33     where the sampler shall look for instrument editor plugins
34     (patch by Luis Garrido, slightly modified).
35 schoenebeck 2121 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
36     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
37     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
38     note (in this implementation of the sampler its simply hard routed to
39     the 1st effect send of the sampler channel, no matter what the actual
40     effect type is)
41     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
42     note (in this implementation of the sampler its simply hard routed to
43     the 2nd effect send of the sampler channel, no matter what the actual
44     effect type is)
45 schoenebeck 2124 - implemented support for internal LADSPA effects
46 schoenebeck 2140 - raised limit of program change queue from 100 to 512

52     EngineChannel::InstrumentFileName(int index)
53     allowing to retrieve the whole list of files used for the loaded
54     instrument on an engine channel (a.k.a. part). Some GigaStudio
55     instruments for example are splitted over several files like
56     "Foo.gig", "Foo.gx01", "Foo.gx02", ...
57 schoenebeck 2375 - Added new C++ API method Sampler::GetGlobalMaxVoices().
58     - Added new C++ API method Sampler::GetGlobalMaxStreams().

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

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

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

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

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

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

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

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

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

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

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