23 iliev 2012 - Refactoring: moved the independent code from
24     the Gigasampler format engine to base classes
25 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
26     respective profiling code is currently broken
27 schoenebeck 2053 - Introduced support for optional environment variable

36     effect type is)
37     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
38     note (in this implementation of the sampler its simply hard routed to

277 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
278     be switched on by command line option "--stacktrace" (the automatic
279     stacktrace mechanism seems to be broken on most systems at the moment)
280 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
281     a pointer to the launched InstrumentEditor object
282 schoenebeck 1876 - added optional 3rd party user data parameter for following
283     liblinuxsampler C++ API methods: InstrumentEditor::Main(),
284     InstrumentEditor::Launch(),

305 persson 1888 - applied old fixes to the ASIO driver that were included in the
306     previous binary release but accidentally never committed to CVS
307     (fixes #117)
308 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
309     win64)
310 persson 1895 - VST: added support for sample rate and buffer size changes
311     - VST: close editor (Fantasia) when the VST is removed

320     AudioChannel::CopyTo() methods using GCC vector exensions
321     (if available)
322 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
323     exception when getting parameters from a disconnected device
324 schoenebeck 1599
325 persson 1651 * MIDI driver:
326     - added JACK MIDI driver
327 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously

345     instrument database compilable
346 schoenebeck 1930 - added instrument database support on Windows
347     works with both standalone mode and VST plugin.
348     the instruments DB file is located in
349     %USERPROFILE%\.linuxsampler\instruments.db which allows different
350     databases for each windows user
351     if no DB is present it automatically creates the .linuxsampler subdir
352     and then creates an empty DB
353 persson 1943 - fixed recursive import, which was broken on Windows
354 iliev 1603
355 persson 1644 * Gigasampler format engine:

362 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
363     respective FX send MIDI controller was used
364 schoenebeck 1724 - added support for GM global device volume SysEx message
365 schoenebeck 1762 (can be selected at compile time to either apply globally to the
366     whole sampler [default] or only to the sampler channels that are
367     connected to the respective MIDI input port the SysEx message arrived
368     on)
369 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
370     sometimes wrongly killed in the same buffer, causing no sound to
371     be played
372 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
373     which is usally used to switch a part between chromatic sounds and
374     drumkit sounds (as opposed to their common default setting of MIDI
375     part 10 being a drumkit part and all other ones chromatic parts), in
376     LS however one can switch between the first 16 MIDI instrument maps
377     defined for the sampler
378 persson 1764 - made it possible to create multiple sample channels even if the
379     audio thread isn't running
380 persson 1844 - fixed crash when removing channel with active voices (#116)
381 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
382     un-cache the respective sample if it's really not used by any
383     sampler engine anymore
384     - re-cache samples in case they were changed by an instrument editor,
385     e.g. when a sample was added while playing (#82)
386 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
387     same time stamp as the voice's note-on event and occured both in the
388     same audio fragment cycle (fixes bug #112)
389 persson 1858 - added support for the "fine tune" and "pitch bend range"
390     instrument-level gig parameters
391     - fixed minor artifacts in pitch bend handling
392 schoenebeck 1860 - added support for GS Reset SysEx message
393 persson 1862 - allow gig files to use unlimited downward pitch shifting
394     - added a limit check for upward pitch shifting
395 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
396     note was silent
397 persson 1923 - fixed crash happening when a pitch bend event arrived at the
398     same time a new instrument was loading
399 persson 1644
400 schoenebeck 1687 * LSCP server:
401     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
402     react on MIDI data arriving on certain sampler channels (so far only
403     Note-On and Note-Off events are sent via this LSCP event)
404 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
405     react on MIDI data arriving on certain MIDI input devices (so far only
406     Note-On and Note-Off events are sent via this LSCP event)
407 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
408     SET DB_INSTRUMENT FILE_PATH
409 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
410     frontends to send MIDI messages to specific sampler channel
411     - added two additional fields to GET FILE INSTRUMENT INFO command -
412     KEY_BINDINGS and KEYSWITCH_BINDINGS
413 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
414     was incorrect
415 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
416 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
417     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
418     be triggered respectively
419     - added new LSCP command "SET STREAMS" to globally alter the maximum
420     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
421     which will be triggered respectively
422 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
423     a gigedit file dialog is opened)
424 iliev 1848 - close all connections when LSCPServer is deleted
425 iliev 1882 - hard close of all sockets on exit
426 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
427     driver
428 schoenebeck 1687
429 iliev 1761 * Bug fixes:
430     - fixed a crash which occurs when removing a sampler channel waiting
431     to start instrument loading after another channel
432 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
433     instrument loading in progress (bug #113)
434 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
435     instrument with PERSISTENT load mode
436 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
437     - fixed memory leaks when issuing the following LSCP commands:
438     GET AUDIO_OUTPUT_DRIVER INFO
439     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
440     GET MIDI_INPUT_DRIVER INFO
441     GET MIDI_INPUT_DRIVER_PARAMETER INFO
442     - fixed possible compilation error when sqlite is not present
443 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
444 iliev 1847 - fixed crash when changing the audio output device of a sampler
445     channel with loaded instrument and start playing notes
446 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
447 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
448     PowerPC, which probably could cause crashes on that platform
449 persson 1889 - fixed a memory management error which could cause a crash when a
450     plugin was unloaded
451 persson 1896 - bugfix: two private structs had the same name, which could cause
452     problems if the linker chose the wrong constructor
453 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
454     Windows

457 schoenebeck 1560 Version 0.5.1 (6 December 2007)
458 schoenebeck 1454
459     * packaging changes:
460     - added autoconf checks for pthread library
461     - added autoconf check for pthread bug found on certain NPTL-enabled
462     glibc versions (see Gentoo bug report #194076)
463 senoner 1502 - added autoconf checks for MS Windows
464 schoenebeck 1454
465 persson 1455 * general changes:
466     - bugfix: the thread used by an editor plugin didn't die when the
467     editor closed
468 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
469     out all the space. operator--() did not apply size_mask after
470     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
471     order to avoid problems with the _NonVolatileReader functions.
472     - bugfix: Stream.h: added a missing divide by BytesPerSample in
473     GetWriteSpace(). Since this function is currently only used in
474     the stream's qsort() compare function, it didn't trigger any
475     bugs.
476     - Resampler.h, Synthesizer.h: cubic interpolation now works in
477     24bit mode too. Faster method to read 24bit words on little
478     endian machines (x86): replaced 3 byte reads + shifts with a 1
479     unaligned 32bit read and shift
480     - experimental support for MS Windows (MIDI input via MME, AUDIO
481     output via ASIO)
482     - made handling of SIGINT signal (Ctrl-C) a bit more robust
483 iliev 1541 - support for monitoring the total number of active disk streams
484     (new LSCP commands: GET TOTAL_STREAM_COUNT,
485     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
486 persson 1455
487 senoner 1500 * AUDIO driver:
488 persson 1534 - added Windows ASIO low latency audio driver
489 senoner 1500
490 senoner 1485 * MIDI driver:
491 schoenebeck 1495 - added MME Windows MIDI driver
492 senoner 1485
493 schoenebeck 1471 * LSCP server:
494     - added support for Windows style path / filenames, however with
495     forward slash path separators instead of backslash
496     (i.e. "C:/foo/bar.gig")
497 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
498     apostrophes as well
499 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
500     "LIST FILE INSTRUMENTS <file>" and
501     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
502     about an arbitrary instrument file on the system where the sampler is
503     running on
504 schoenebeck 1471
505 schoenebeck 1424 Version 0.5.0 (15 October 2007)
506 schoenebeck 947
507 schoenebeck 1065 * packaging changes:
508 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
509     API header files anymore
510 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
511     the Doxygen API documentation (explicitly listed in Doxyfile.in)
512 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
513     capable to execute our autoconf environment, thus no need anymore
514     to maintain the compile time configuration file (osx/version.h) for
515     OSX manually (patch by Toshi Nagata)
516 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
517     parameters
518 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
519     C++ API header files, all implementation internal global definitions
520     are now in global_private.h
521     - atomic.h is not exposed to the C++ API anymore
522     - no need to include config.h anymore for using LS's API header files
523     - fixed warnings in API doc generation
524 schoenebeck 1065
525 schoenebeck 947 * general changes:
526     - replaced the old, confusing MIDI program change mechanism by a
527     flexible MIDI instrument mapper which allows to map arbitrary
528 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
529 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
530     loaded on the respective channel when such MIDI program change
531     messages arrive, beside that, each entry allows to define a life-time
532     strategy for the instrument, so the user can define whether the
533     instrument should i.e. be permanently loaded (to be able to switch
534     quickly among sounds) or i.e. loaded just on demand when the
535     respective program change arrives (to safe RAM space), as well as a
536     global volume factor for each entry, so the user can adjust the volume
537     dynamic of his mapped instrument collection without having to modify
538 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
539     MIDI instrument maps and assign each sampler channel individually
540     a certain map, so that i.e. separation of normal instruments and
541     drumkits is possible
542 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
543     MIDI instrument maps, MIDI instruments, FX sends, global volume.
544 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
545     due to a constant size RingBuffer FIFO which is now replaced by a
546     dynamic (unlimited) size std::list FIFO
547 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
548     output channels for being processed by external effect processors
549     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
550     controllers
551 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
552 iliev 1130 - Implemented new, improved notification system
553 schoenebeck 1149 - fixed compilation errors regarding OSX
554     (patch by Toshi Nagata)
555 iliev 1161 - implemented instruments database
556 iliev 1345 - added support for escape sequences to the instruments database
557 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
558     within the sampler's process (by using instrument editor plugins),
559     you'll notice the new "Registered instrument editors:" message on
560 schoenebeck 1407 startup, added a new LSCP command:
561     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
562 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
563     given sampler channel, the plugin path can be overridden at compile
564     time with ./configure --enable-plugin-dir=/some/dir
565 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
566     in the sampler's process to safely edit instruments while playing
567     without a crash (hopefully) by either suspending single regions
568     wherever possible or if unavoidable whole engine(s)
569 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
570     policy and priority on thread level, set a minimum stack size for
571     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
572     threads simply inherited properties of starting thread instead of
573     setting their own policy and priority
574 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
575     main process did not wait for the stack trace process to finish
576     its output
577 persson 1248 - fixed some minor memory leaks
578 schoenebeck 1259 - reenabled assembly features support, at the moment only for
579     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
580 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
581     register, to avoid relocations in the text segment at runtime)
582 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
583 schoenebeck 947
584     * MIDI driver:
585     - dispatch bank select (MSB and LSB) messages
586    
587 schoenebeck 1049 * audio driver:
588     - the ALSA audio output driver parameters now reflect the correct
589     parameter value ranges for the respective selected sound card
590     (patch by Till Wimmer, a bit fixed and extended)
591    
592 persson 951 * Gigasampler format engine:
593     - if a filter is used and EG2 finishes before EG1, let the voice
594     die when EG2 has finished (this fixes a problem with clicks and
595     voice starvation for some gigs)
596 persson 1038 - playback is no longer disabled during instrument loading
597     - all notes playing on a channel that changes its instrument keep
598     playing with the old instrument until they get a note off
599     command
600 persson 1039 - EG fix: a release value of zero could cause noises or crash
601 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
602 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
603     above max sustain level, which means that there is a decay phase
604     even if sustain is 100%
605 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
606     noises or crashes
607 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
608 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
609     supplied to the configure script (fixes #46)
610 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
611     instead of a fix value
612 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
613     127 (solo mode) only kill voices if the respective mode really
614     changed
615 persson 951
616 schoenebeck 1244 * LSCP server:
617     - fixed compile time error for old Bison versions
618     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
619 schoenebeck 1245 - parser now supports extended ASCII character set
620     (up to ASCII code 255, i.e. includes now umlauts and accents)
621     - filename arguments in LSCP commands now allow to use escape
622     sequences, that is directly literal as one of: \', \", \\, \n, \r,
623     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
624     code value like \xf2) (fixes bug #24)
625 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
626     least one of their text-based parameters (i.e. name, description):
627     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
628     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
629     "SET DB_INSTRUMENT_DIRECTORY NAME",
630     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
631     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
632     "FIND DB_INSTRUMENT_DIRECTORIES"
633 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
634     occured, the unexpected character and the actually expected, possible
635     character(s), the latter only if less than 5 possibilities)
636 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
637     settings
638 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
639     of strings were treated as being one string containing commas
640     (fixes #57)
641 schoenebeck 1244
642 iliev 959 * Bug fixes:
643     - fixed crash occurring on certain LSCP scripts (Bug 39)
644 persson 1038 - another thread safety fix for lscp "load engine" and "set
645     channel audio output device"
646 iliev 1283 - fixed a crash which occurs when reassigning the same engine
647     on a sampler channel with connected MIDI device
648 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
649     device connected to a sampler channel to number less then or equal
650     to the index of the port to which the sampler channel is connected.
651 iliev 1296 - The previous bindings were not been disconnected when altering
652     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
653     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
654 iliev 1297 - The active stream/voice count statistic was incorrect.
655 iliev 1298 - notification events were not been sent for some sampler
656     channel changes
657 iliev 1305 - added default min and max values to restrict the number of allowed
658     audio output channels and MIDI input ports
659 iliev 1306 - the connection to the PCM interface is now closed when destroying
660     an audio output device
661 schoenebeck 1332 - files with slash in their path or filename could not be loaded
662 iliev 959
663 schoenebeck 1221 * test cases:
664     - updated and fixed (haven't been touched in a while)
665    
666 schoenebeck 937 Version 0.4.0 (24 November 2006)
667 persson 696
668 schoenebeck 697 * packaging changes:
669 capela 868 - changed deprecated copyright attribute to license; added ldconfig
670     to post-(un)install steps; added devel package for liblinuxsampler;
671     to linuxsampler.spec (RPM)
672 schoenebeck 697 - install necessary development header files for allowing 3rd party
673     applications to link against liblinuxsampler
674     - liblinuxsampler's API documentation can be generated with 'make docs'
675     (Doxygen required)
676 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
677     implementation (currently either an integer math solution or a
678     di-harmonic approximation), automatic detection can be overriden
679     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
680     configure script argument though (mandatory for cross-compilation)
681 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
682     provided some on his own (as CXXFLAGS)
683 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
684     messages
685 schoenebeck 852 - added compile time options to allow disabling the various audio and
686     MIDI drivers
687 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
688     (patch by Ebrahim Mayat)
689 schoenebeck 697
690 persson 696 * Gigasampler format engine:
691 schoenebeck 738 - extensive synthesis optimization
692     (reimplementation of EGs and LFO(s), removed synthesis parameter
693     prerendering and the synthesis parameter matrix in general, splitting
694     each audio fragment into subfragments now where each subfragment uses
695 persson 830 constant pitch and filter coefficients. The volume coefficient is
696     linearly interpolated inside a subfragment, unless
697     --disable-interpolate-volume is set.)
698 persson 696 - fine tuning of the EG modulation parameters
699 persson 729 - improved filter cutoff calculation by adding support for the
700     following gig parameters: Cutoff freq (used when no cutoff
701     controller is defined), Control invert, Minimum cutoff, Velocity
702 persson 791 curve and Velocity range. The keyboard tracking now scales
703     cutoff frequency instead of resonance.
704 persson 877 - added support for gig parameter Resonance.
705 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
706 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
707     which can be overridden with --enable-global-attenuation
708 persson 783 - EG fixes: made the length of "attack hold" stage more
709     accurate. Release stage can now start before attack stage
710 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
711     time now has a minimal value to prevent clicks.
712 persson 799 - fixed pitch changes larger than one octave
713 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
714     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
715     all modes can be altered via standard GM messages, that is CC5 for
716     altering portamento time, CC65 for enabling / disabling portamento
717     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
718 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
719     parameter) and crossfade
720 persson 831 - added support for the "attenuation controller threshold" gig
721     parameter
722 persson 832 - added smoothing of volume changes caused by control change
723     messages
724 persson 865 - sample loop parameters are now taken from the DimensionRegion
725     instead of the wave chunk
726     - fixed keyswitching for v3 gigs with a number of keyswitch splits
727     not equal to a power of two
728 persson 877 - reimplementation of the filter algorithm. The new filter is more
729     accurate and supports all gig filter types, including bandreject
730     and lowpass turbo.
731 persson 903 - real support for 24 bit samples - samples are not truncated to
732     16 bits anymore
733     - support for aftertouch (channel pressure, not polyphonic
734     aftertouch)
735 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
736     amplifying from 0)
737 persson 696
738 schoenebeck 711 * LSCP server:
739     - fixed application exit on broken pipe error (fixes bug #20)
740 iliev 793 - fixed the notification messages delay due to lack of
741     network activity (fixes bug #26)
742 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
743     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
744 schoenebeck 711
745 schoenebeck 838 * audio driver:
746     - added aRts audio output driver (by no means RT safe)
747    
748 schoenebeck 775 * MIDI driver:
749     - fixed legacy sysex code which caused dispatching of MIDI SysEx
750     messages several times instead of once
751 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
752     for events (i.e. for offline rendering based MIDI drivers)
753 persson 922 - added checks for bad MIDI data
754 schoenebeck 775
755 schoenebeck 900 * linuxsampler application:
756     - show available sampler engine types on startup
757    
758 schoenebeck 705 * general changes:
759     - support for muting sampler channels and solo mode of the same, two new
760     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
761     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
762     introduced for this, the behavior is the same like on a mixer console
763 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
764     --enable-process-muted-channels which can be used to enable the
765     processing of muted channels.
766 iliev 777 - support for sostenuto pedal
767 iliev 779 - support for monitoring the total number of active voices
768 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
769     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
770 persson 835 - fixed some memory management errors
771 persson 841 - fixed some concurrency problems that could lead to crashes when
772     LSCP commands were executed
773 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
774     sampler channel (fixes bug #36)
775 schoenebeck 705
776 schoenebeck 692 Version 0.3.3 (15 July 2005)
777 schoenebeck 686
778     * packaging changes:
779     - fixed compilation with gcc 4.0
780    
781 schoenebeck 687 * Gigasampler format engine:
782     - LFO preprocessing was performed even though the respective LFO was
783     disabled by the instrument patch (minor efficiency fix)
784 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
785     for volume ramp downs in the same fragment (needed for current voice
786     stealing implementation) then simply inform the user with a warning
787     about possible click sounds and reduce the volume ramp down
788     appropriately instead of cancelling the audio device connection
789 schoenebeck 687
790 schoenebeck 677 Version 0.3.2 (24 June 2005)
791 schoenebeck 609
792     * packaging changes:
793     - updated autotools build files to compile on OS X
794     (conditional compilation of CoreMIDI and MidiShare drivers)
795 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
796     './configure --disable-asm' (definitely not recommended)
797 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
798     - require automake (>= 1.5) for 'make -f Makefile.cvs'
799     (due to 'dist-bzip2' automake option)
800 schoenebeck 649
801     * Gigasampler format engine:
802     - support for the gig parameters for "release velocity response" curves
803     - fine tuning of the EGADSR envelope
804     - volume of release triggered samples now depends on note-on velocity,
805     note length and gig parameter "release trigger decay" instead of
806     note-off velocity.
807 schoenebeck 663 - revised voice stealing
808     (fixes crash and endless loop caused by voice stealing)
809 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
810 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
811     instead of when the respective voice is actually launched
812     (fixes undefined behavior if stolen voices belonged to a key group -
813     this case was followed by a "killed voice survived" error message)
814 schoenebeck 669 - fixed minor issue with null/silence samples
815     (those stole voices even though they don't need a voice at all which
816     resulted in "voice stealing didn't work out" messages)
817 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
818     instrument or audio output device change
819 schoenebeck 654
820 schoenebeck 620 * LSCP server:
821 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
822 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
823 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
824 schoenebeck 609
825 schoenebeck 668 * linuxsampler application:
826     - added command line parameters --lscp-addr and --lscp-port to override
827     default IP address and port of LSCP server
828    
829 schoenebeck 579 Version 0.3.1 (24 May 2005)
830    
831     * initial release
