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

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

26 persson 2382
27 persson 2086 * general changes:
28 iliev 2012 - Refactoring: moved the independent code from
29     the Gigasampler format engine to base classes
30 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
31     respective profiling code is currently broken
32 schoenebeck 2053 - Introduced support for optional environment variable
33     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
34     where the sampler shall look for instrument editor plugins
35     (patch by Luis Garrido, slightly modified).
36 schoenebeck 2121 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
37     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
38     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
39     note (in this implementation of the sampler its simply hard routed to
40     the 1st effect send of the sampler channel, no matter what the actual
41     effect type is)
42     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
43     note (in this implementation of the sampler its simply hard routed to
44     the 2nd effect send of the sampler channel, no matter what the actual
45     effect type is)
46 schoenebeck 2124 - implemented support for internal LADSPA effects
47 schoenebeck 2140 - raised limit of program change queue from 100 to 512

55     instrument on an engine channel (a.k.a. part). Some GigaStudio
56     instruments for example are splitted over several files like
57     "Foo.gig", "Foo.gx01", "Foo.gx02", ...
58 schoenebeck 2375 - Added new C++ API method Sampler::GetGlobalMaxVoices().
59     - Added new C++ API method Sampler::GetGlobalMaxStreams().

72     key
73 persson 2382 - bugfix: pitch LFO controller "internal+aftertouch" was broken
74     - bugfix: filter keyboard tracking was broken
75     - filter performance fix (an unnecessary copy was made of the

77     - handle special case when pan parameter in gig file has max or
78     min value
79 schoenebeck 2396 - Exclusive Groups: don't ever stop voices of the same note,

294     to them a la JACK, via the usual sampler APIs
295     - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
296     the driver will automatically connect to other CoreMIDI clients' ports
297     (e.g. external MIDI devices being attached to the Mac)

360 iliev 2201 - Fixed possible crashes due to corrupted MIDI/audio device list
361     after MIDI/audio device creation failure
362 schoenebeck 2275 - When creating MIDI instrument map entries with "PERSISTENT" type, the
363     instruments were uselessly precached with zero samples, however it still
364     took the full preloading time and on 1st program change the respective
365     instrument was completely reloaded again.
366 persson 2277 - fixed handling of rapid bank select and program change messages
367     sent to the same sampler channel (patch from the Open Octave

388 schoenebeck 1599
389 schoenebeck 1639 * packaging changes:
390     - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

435 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
436     be switched on by command line option "--stacktrace" (the automatic
437     stacktrace mechanism seems to be broken on most systems at the moment)
438 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
439     a pointer to the launched InstrumentEditor object
440 schoenebeck 1876 - added optional 3rd party user data parameter for following

452     - removed the nonsense audio channel constraint (which was hard coded to
453     max. 100 audio channels) for most audio drivers
454 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
455     opposed to the LSCP specs
456 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
457     reflected the wrong value
458 persson 1644 - fixed a memory management bug in ASIO driver
459 persson 1748 - Makefile fix: JACK_CFLAGS wasn't used

461 persson 1748 jack_client_new
462 iliev 1829 - added (experimental) CoreAudio driver
463 persson 1888 - applied old fixes to the ASIO driver that were included in the
464     previous binary release but accidentally never committed to CVS
465     (fixes #117)
466 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
467     win64)
468 persson 1895 - VST: added support for sample rate and buffer size changes
469     - VST: close editor (Fantasia) when the VST is removed

478     AudioChannel::CopyTo() methods using GCC vector exensions
479     (if available)
480 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
481     exception when getting parameters from a disconnected device
482 schoenebeck 1599
483 persson 1651 * MIDI driver:
484     - added JACK MIDI driver
485 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
486     want to (mis)use it for some purpose ("fixed" in all current MIDI
487     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
488 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
489 persson 1887 CoreMidi or AU
490 persson 1889 - fixed mingw-w64 compilation error in MME driver
491 persson 1924 - made program change handling in MIDI thread real-time safe by

497     to the instruments database
498 iliev 1727 - added support for handling lost files in the instruments database
499 iliev 1781 - Implemented option for adding instruments in separate directories
500     in the instruments database

502 persson 1908 - work-around for missing fnmatch function on Windows to make
503     instrument database compilable
504 schoenebeck 1930 - added instrument database support on Windows
505     works with both standalone mode and VST plugin.
506     the instruments DB file is located in
507     %USERPROFILE%\.linuxsampler\instruments.db which allows different
508     databases for each windows user
509     if no DB is present it automatically creates the .linuxsampler subdir
510     and then creates an empty DB
511 persson 1943 - fixed recursive import, which was broken on Windows
512 iliev 1603
513 persson 1644 * Gigasampler format engine:
514     - fixed a memory leak that could happen when a channel was deleted

516 persson 1646 - made it possible to load an instrument even if the audio thread
517     isn't running
518 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
519     enough for piano gigs with pedal noise samples
520 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
521     respective FX send MIDI controller was used
522 schoenebeck 1724 - added support for GM global device volume SysEx message
523 schoenebeck 1762 (can be selected at compile time to either apply globally to the
524     whole sampler [default] or only to the sampler channels that are
525     connected to the respective MIDI input port the SysEx message arrived
526     on)
527 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
528     sometimes wrongly killed in the same buffer, causing no sound to
529     be played
530 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
531     which is usally used to switch a part between chromatic sounds and
532     drumkit sounds (as opposed to their common default setting of MIDI
533     part 10 being a drumkit part and all other ones chromatic parts), in
534     LS however one can switch between the first 16 MIDI instrument maps
535     defined for the sampler
536 persson 1764 - made it possible to create multiple sample channels even if the
537     audio thread isn't running
538 persson 1844 - fixed crash when removing channel with active voices (#116)
539 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
540     un-cache the respective sample if it's really not used by any
541     sampler engine anymore
542     - re-cache samples in case they were changed by an instrument editor,
543     e.g. when a sample was added while playing (#82)
544 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
545     same time stamp as the voice's note-on event and occured both in the
546     same audio fragment cycle (fixes bug #112)
547 persson 1858 - added support for the "fine tune" and "pitch bend range"
548     instrument-level gig parameters
549     - fixed minor artifacts in pitch bend handling
550 schoenebeck 1860 - added support for GS Reset SysEx message
551 persson 1862 - allow gig files to use unlimited downward pitch shifting
552     - added a limit check for upward pitch shifting
553 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
554     note was silent
555 persson 1923 - fixed crash happening when a pitch bend event arrived at the
556     same time a new instrument was loading
557 persson 1644
558 schoenebeck 1687 * LSCP server:
559     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
560     react on MIDI data arriving on certain sampler channels (so far only
561     Note-On and Note-Off events are sent via this LSCP event)
562 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
563     react on MIDI data arriving on certain MIDI input devices (so far only
564     Note-On and Note-Off events are sent via this LSCP event)
565 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
566     SET DB_INSTRUMENT FILE_PATH
567 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
568     frontends to send MIDI messages to specific sampler channel
569     - added two additional fields to GET FILE INSTRUMENT INFO command -
570     KEY_BINDINGS and KEYSWITCH_BINDINGS
571 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
572     was incorrect
573 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
574 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
575     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
576     be triggered respectively
577     - added new LSCP command "SET STREAMS" to globally alter the maximum
578     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
579     which will be triggered respectively
580 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
581     a gigedit file dialog is opened)
582 iliev 1848 - close all connections when LSCPServer is deleted
583 iliev 1882 - hard close of all sockets on exit
584 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
585     driver
586 schoenebeck 1687
587 iliev 1761 * Bug fixes:
588     - fixed a crash which occurs when removing a sampler channel waiting
589     to start instrument loading after another channel
590 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
591     instrument loading in progress (bug #113)
592 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
593     instrument with PERSISTENT load mode
594 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
595     - fixed memory leaks when issuing the following LSCP commands:
596     GET AUDIO_OUTPUT_DRIVER INFO
597     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
598     GET MIDI_INPUT_DRIVER INFO
599     GET MIDI_INPUT_DRIVER_PARAMETER INFO
600     - fixed possible compilation error when sqlite is not present
601 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
602 iliev 1847 - fixed crash when changing the audio output device of a sampler
603     channel with loaded instrument and start playing notes
604 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
605 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
606     PowerPC, which probably could cause crashes on that platform
607 persson 1889 - fixed a memory management error which could cause a crash when a
608     plugin was unloaded
609 persson 1896 - bugfix: two private structs had the same name, which could cause
610     problems if the linker chose the wrong constructor
611 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
612     Windows
613 iliev 1761
614    
615 schoenebeck 1560 Version 0.5.1 (6 December 2007)
616 schoenebeck 1454
617     * packaging changes:
618     - added autoconf checks for pthread library
619     - added autoconf check for pthread bug found on certain NPTL-enabled
620     glibc versions (see Gentoo bug report #194076)
621 senoner 1502 - added autoconf checks for MS Windows
622 schoenebeck 1454
623 persson 1455 * general changes:
624     - bugfix: the thread used by an editor plugin didn't die when the
625     editor closed
626 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
627     out all the space. operator--() did not apply size_mask after
628     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
629     order to avoid problems with the _NonVolatileReader functions.
630     - bugfix: Stream.h: added a missing divide by BytesPerSample in
631     GetWriteSpace(). Since this function is currently only used in
632     the stream's qsort() compare function, it didn't trigger any
633     bugs.
634     - Resampler.h, Synthesizer.h: cubic interpolation now works in
635     24bit mode too. Faster method to read 24bit words on little
636     endian machines (x86): replaced 3 byte reads + shifts with a 1
637     unaligned 32bit read and shift
638     - experimental support for MS Windows (MIDI input via MME, AUDIO
639     output via ASIO)
640     - made handling of SIGINT signal (Ctrl-C) a bit more robust
641 iliev 1541 - support for monitoring the total number of active disk streams
642     (new LSCP commands: GET TOTAL_STREAM_COUNT,
643     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
644 persson 1455
645 senoner 1500 * AUDIO driver:
646 persson 1534 - added Windows ASIO low latency audio driver
647 senoner 1500
648 senoner 1485 * MIDI driver:
649 schoenebeck 1495 - added MME Windows MIDI driver
650 senoner 1485
651 schoenebeck 1471 * LSCP server:
652     - added support for Windows style path / filenames, however with
653     forward slash path separators instead of backslash
654     (i.e. "C:/foo/bar.gig")
655 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
656     apostrophes as well
657 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
658     "LIST FILE INSTRUMENTS <file>" and
659     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
660     about an arbitrary instrument file on the system where the sampler is
661     running on
662 schoenebeck 1471
663 schoenebeck 1424 Version 0.5.0 (15 October 2007)
664 schoenebeck 947
665 schoenebeck 1065 * packaging changes:
666 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
667     API header files anymore
668 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
669     the Doxygen API documentation (explicitly listed in Doxyfile.in)
670 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
671     capable to execute our autoconf environment, thus no need anymore
672     to maintain the compile time configuration file (osx/version.h) for
673     OSX manually (patch by Toshi Nagata)
674 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
675     parameters
676 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
677     C++ API header files, all implementation internal global definitions
678     are now in global_private.h
679     - atomic.h is not exposed to the C++ API anymore
680     - no need to include config.h anymore for using LS's API header files
681     - fixed warnings in API doc generation
682 schoenebeck 1065
683 schoenebeck 947 * general changes:
684     - replaced the old, confusing MIDI program change mechanism by a
685     flexible MIDI instrument mapper which allows to map arbitrary
686 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
687 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
688     loaded on the respective channel when such MIDI program change
689     messages arrive, beside that, each entry allows to define a life-time
690     strategy for the instrument, so the user can define whether the
691     instrument should i.e. be permanently loaded (to be able to switch
692     quickly among sounds) or i.e. loaded just on demand when the
693     respective program change arrives (to safe RAM space), as well as a
694     global volume factor for each entry, so the user can adjust the volume
695     dynamic of his mapped instrument collection without having to modify
696 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
697     MIDI instrument maps and assign each sampler channel individually
698     a certain map, so that i.e. separation of normal instruments and
699     drumkits is possible
700 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
701     MIDI instrument maps, MIDI instruments, FX sends, global volume.
702 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
703     due to a constant size RingBuffer FIFO which is now replaced by a
704     dynamic (unlimited) size std::list FIFO
705 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
706     output channels for being processed by external effect processors
707     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
708     controllers
709 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
710 iliev 1130 - Implemented new, improved notification system
711 schoenebeck 1149 - fixed compilation errors regarding OSX
712     (patch by Toshi Nagata)
713 iliev 1161 - implemented instruments database
714 iliev 1345 - added support for escape sequences to the instruments database
715 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
716     within the sampler's process (by using instrument editor plugins),
717     you'll notice the new "Registered instrument editors:" message on
718 schoenebeck 1407 startup, added a new LSCP command:
719     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
720 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
721     given sampler channel, the plugin path can be overridden at compile
722     time with ./configure --enable-plugin-dir=/some/dir
723 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
724     in the sampler's process to safely edit instruments while playing
725     without a crash (hopefully) by either suspending single regions
726     wherever possible or if unavoidable whole engine(s)
727 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
728     policy and priority on thread level, set a minimum stack size for
729     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
730     threads simply inherited properties of starting thread instead of
731     setting their own policy and priority
732 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
733     main process did not wait for the stack trace process to finish
734     its output
735 persson 1248 - fixed some minor memory leaks
736 schoenebeck 1259 - reenabled assembly features support, at the moment only for
737     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
738 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
739     register, to avoid relocations in the text segment at runtime)
740 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
741 schoenebeck 947
742     * MIDI driver:
743     - dispatch bank select (MSB and LSB) messages
744    
745 schoenebeck 1049 * audio driver:
746     - the ALSA audio output driver parameters now reflect the correct
747     parameter value ranges for the respective selected sound card
748     (patch by Till Wimmer, a bit fixed and extended)
749    
750 persson 951 * Gigasampler format engine:
751     - if a filter is used and EG2 finishes before EG1, let the voice
752     die when EG2 has finished (this fixes a problem with clicks and
753     voice starvation for some gigs)
754 persson 1038 - playback is no longer disabled during instrument loading
755     - all notes playing on a channel that changes its instrument keep
756     playing with the old instrument until they get a note off
757     command
758 persson 1039 - EG fix: a release value of zero could cause noises or crash
759 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
760 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
761     above max sustain level, which means that there is a decay phase
762     even if sustain is 100%
763 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
764     noises or crashes
765 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
766 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
767     supplied to the configure script (fixes #46)
768 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
769     instead of a fix value
770 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
771     127 (solo mode) only kill voices if the respective mode really
772     changed
773 persson 951
774 schoenebeck 1244 * LSCP server:
775     - fixed compile time error for old Bison versions
776     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
777 schoenebeck 1245 - parser now supports extended ASCII character set
778     (up to ASCII code 255, i.e. includes now umlauts and accents)
779     - filename arguments in LSCP commands now allow to use escape
780     sequences, that is directly literal as one of: \', \", \\, \n, \r,
781     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
782     code value like \xf2) (fixes bug #24)
783 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
784     least one of their text-based parameters (i.e. name, description):
785     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
786     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
787     "SET DB_INSTRUMENT_DIRECTORY NAME",
788     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
789     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
790     "FIND DB_INSTRUMENT_DIRECTORIES"
791 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
792     occured, the unexpected character and the actually expected, possible
793     character(s), the latter only if less than 5 possibilities)
794 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
795     settings
796 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
797     of strings were treated as being one string containing commas
798     (fixes #57)
799 schoenebeck 1244
800 iliev 959 * Bug fixes:
801     - fixed crash occurring on certain LSCP scripts (Bug 39)
802 persson 1038 - another thread safety fix for lscp "load engine" and "set
803     channel audio output device"
804 iliev 1283 - fixed a crash which occurs when reassigning the same engine
805     on a sampler channel with connected MIDI device
806 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
807     device connected to a sampler channel to number less then or equal
808     to the index of the port to which the sampler channel is connected.
809 iliev 1296 - The previous bindings were not been disconnected when altering
810     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
811     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
812 iliev 1297 - The active stream/voice count statistic was incorrect.
813 iliev 1298 - notification events were not been sent for some sampler
814     channel changes
815 iliev 1305 - added default min and max values to restrict the number of allowed
816     audio output channels and MIDI input ports
817 iliev 1306 - the connection to the PCM interface is now closed when destroying
818     an audio output device
819 schoenebeck 1332 - files with slash in their path or filename could not be loaded
820 iliev 959
821 schoenebeck 1221 * test cases:
822     - updated and fixed (haven't been touched in a while)
823    
824 schoenebeck 937 Version 0.4.0 (24 November 2006)
825 persson 696
826 schoenebeck 697 * packaging changes:
827 capela 868 - changed deprecated copyright attribute to license; added ldconfig
828     to post-(un)install steps; added devel package for liblinuxsampler;
829     to linuxsampler.spec (RPM)
830 schoenebeck 697 - install necessary development header files for allowing 3rd party
831     applications to link against liblinuxsampler
832     - liblinuxsampler's API documentation can be generated with 'make docs'
833     (Doxygen required)
834 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
835     implementation (currently either an integer math solution or a
836     di-harmonic approximation), automatic detection can be overriden
837     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
838     configure script argument though (mandatory for cross-compilation)
839 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
840     provided some on his own (as CXXFLAGS)
841 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
842     messages
843 schoenebeck 852 - added compile time options to allow disabling the various audio and
844     MIDI drivers
845 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
846     (patch by Ebrahim Mayat)
847 schoenebeck 697
848 persson 696 * Gigasampler format engine:
849 schoenebeck 738 - extensive synthesis optimization
850     (reimplementation of EGs and LFO(s), removed synthesis parameter
851     prerendering and the synthesis parameter matrix in general, splitting
852     each audio fragment into subfragments now where each subfragment uses
853 persson 830 constant pitch and filter coefficients. The volume coefficient is
854     linearly interpolated inside a subfragment, unless
855     --disable-interpolate-volume is set.)
856 persson 696 - fine tuning of the EG modulation parameters
857 persson 729 - improved filter cutoff calculation by adding support for the
858     following gig parameters: Cutoff freq (used when no cutoff
859     controller is defined), Control invert, Minimum cutoff, Velocity
860 persson 791 curve and Velocity range. The keyboard tracking now scales
861     cutoff frequency instead of resonance.
862 persson 877 - added support for gig parameter Resonance.
863 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
864 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
865     which can be overridden with --enable-global-attenuation
866 persson 783 - EG fixes: made the length of "attack hold" stage more
867     accurate. Release stage can now start before attack stage
868 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
869     time now has a minimal value to prevent clicks.
870 persson 799 - fixed pitch changes larger than one octave
871 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
872     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
873     all modes can be altered via standard GM messages, that is CC5 for
874     altering portamento time, CC65 for enabling / disabling portamento
875     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
876 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
877     parameter) and crossfade
878 persson 831 - added support for the "attenuation controller threshold" gig
879     parameter
880 persson 832 - added smoothing of volume changes caused by control change
881     messages
882 persson 865 - sample loop parameters are now taken from the DimensionRegion
883     instead of the wave chunk
884     - fixed keyswitching for v3 gigs with a number of keyswitch splits
885     not equal to a power of two
886 persson 877 - reimplementation of the filter algorithm. The new filter is more
887     accurate and supports all gig filter types, including bandreject
888     and lowpass turbo.
889 persson 903 - real support for 24 bit samples - samples are not truncated to
890     16 bits anymore
891     - support for aftertouch (channel pressure, not polyphonic
892     aftertouch)
893 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
894     amplifying from 0)
895 persson 696
896 schoenebeck 711 * LSCP server:
897     - fixed application exit on broken pipe error (fixes bug #20)
898 iliev 793 - fixed the notification messages delay due to lack of
899     network activity (fixes bug #26)
900 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
901     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
902 schoenebeck 711
903 schoenebeck 838 * audio driver:
904     - added aRts audio output driver (by no means RT safe)
905    
906 schoenebeck 775 * MIDI driver:
907     - fixed legacy sysex code which caused dispatching of MIDI SysEx
908     messages several times instead of once
909 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
910     for events (i.e. for offline rendering based MIDI drivers)
911 persson 922 - added checks for bad MIDI data
912 schoenebeck 775
913 schoenebeck 900 * linuxsampler application:
914     - show available sampler engine types on startup
915    
916 schoenebeck 705 * general changes:
917     - support for muting sampler channels and solo mode of the same, two new
918     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
919     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
920     introduced for this, the behavior is the same like on a mixer console
921 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
922     --enable-process-muted-channels which can be used to enable the
923     processing of muted channels.
924 iliev 777 - support for sostenuto pedal
925 iliev 779 - support for monitoring the total number of active voices
926 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
927     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
928 persson 835 - fixed some memory management errors
929 persson 841 - fixed some concurrency problems that could lead to crashes when
930     LSCP commands were executed
931 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
932     sampler channel (fixes bug #36)
933 schoenebeck 705
934 schoenebeck 692 Version 0.3.3 (15 July 2005)
935 schoenebeck 686
936     * packaging changes:
937     - fixed compilation with gcc 4.0
938    
939 schoenebeck 687 * Gigasampler format engine:
940     - LFO preprocessing was performed even though the respective LFO was
941     disabled by the instrument patch (minor efficiency fix)
942 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
943     for volume ramp downs in the same fragment (needed for current voice
944     stealing implementation) then simply inform the user with a warning
945     about possible click sounds and reduce the volume ramp down
946     appropriately instead of cancelling the audio device connection
947 schoenebeck 687
948 schoenebeck 677 Version 0.3.2 (24 June 2005)
949 schoenebeck 609
950     * packaging changes:
951     - updated autotools build files to compile on OS X
952     (conditional compilation of CoreMIDI and MidiShare drivers)
953 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
954     './configure --disable-asm' (definitely not recommended)
955 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
956     - require automake (>= 1.5) for 'make -f Makefile.cvs'
957     (due to 'dist-bzip2' automake option)
958 schoenebeck 649
959     * Gigasampler format engine:
960     - support for the gig parameters for "release velocity response" curves
961     - fine tuning of the EGADSR envelope
962     - volume of release triggered samples now depends on note-on velocity,
963     note length and gig parameter "release trigger decay" instead of
964     note-off velocity.
965 schoenebeck 663 - revised voice stealing
966     (fixes crash and endless loop caused by voice stealing)
967 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
968 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
969     instead of when the respective voice is actually launched
970     (fixes undefined behavior if stolen voices belonged to a key group -
971     this case was followed by a "killed voice survived" error message)
972 schoenebeck 669 - fixed minor issue with null/silence samples
973     (those stole voices even though they don't need a voice at all which
974     resulted in "voice stealing didn't work out" messages)
975 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
976     instrument or audio output device change
977 schoenebeck 654
978 schoenebeck 620 * LSCP server:
979 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
980 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
981 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
982 schoenebeck 609
983 schoenebeck 668 * linuxsampler application:
984     - added command line parameters --lscp-addr and --lscp-port to override
985     default IP address and port of LSCP server
986    
987 schoenebeck 579 Version 0.3.1 (24 May 2005)
988    
989     * initial release
