22     * general changes:
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

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

225 schoenebeck 1599
226 schoenebeck 1639 * packaging changes:
227     - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

245 schoenebeck 1639
246 schoenebeck 1601 * general changes:
247     - bugfix: on some POSIX systems instrument editor plugins refused to

272 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
273     be switched on by command line option "--stacktrace" (the automatic
274     stacktrace mechanism seems to be broken on most systems at the moment)
275 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
276     a pointer to the launched InstrumentEditor object
277 schoenebeck 1876 - added optional 3rd party user data parameter for following
278     liblinuxsampler C++ API methods: InstrumentEditor::Main(),
279     InstrumentEditor::Launch(),
280     InstrumentManager::LaunchInstrumentEditor()
281 persson 1887 - theoretical fix: made SynchronizedConfig follow C++0x memory
282     model more strictly
283 persson 1895 - fixes for using large audio device buffers

299 iliev 1829 - added (experimental) CoreAudio driver
300 persson 1888 - applied old fixes to the ASIO driver that were included in the
301     previous binary release but accidentally never committed to CVS
302     (fixes #117)
303 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
304     win64)
305 persson 1895 - VST: added support for sample rate and buffer size changes
306     - VST: close editor (Fantasia) when the VST is removed

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

324     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
325 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
326 persson 1887 CoreMidi or AU

339 persson 1908 - work-around for missing fnmatch function on Windows to make
340     instrument database compilable
341 schoenebeck 1930 - added instrument database support on Windows
342     works with both standalone mode and VST plugin.
343     the instruments DB file is located in
344     %USERPROFILE%\.linuxsampler\instruments.db which allows different
345     databases for each windows user
346     if no DB is present it automatically creates the .linuxsampler subdir
347     and then creates an empty DB
348 persson 1943 - fixed recursive import, which was broken on Windows
349 iliev 1603
350 persson 1644 * Gigasampler format engine:
351     - fixed a memory leak that could happen when a channel was deleted
352     while notes were playing
353 persson 1646 - made it possible to load an instrument even if the audio thread
354     isn't running
355 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
356     enough for piano gigs with pedal noise samples
357 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
358     respective FX send MIDI controller was used
359 schoenebeck 1724 - added support for GM global device volume SysEx message
360 schoenebeck 1762 (can be selected at compile time to either apply globally to the
361     whole sampler [default] or only to the sampler channels that are
362     connected to the respective MIDI input port the SysEx message arrived
363     on)
364 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
365     sometimes wrongly killed in the same buffer, causing no sound to
366     be played
367 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
368     which is usally used to switch a part between chromatic sounds and
369     drumkit sounds (as opposed to their common default setting of MIDI
370     part 10 being a drumkit part and all other ones chromatic parts), in
371     LS however one can switch between the first 16 MIDI instrument maps
372     defined for the sampler
373 persson 1764 - made it possible to create multiple sample channels even if the
374     audio thread isn't running
375 persson 1844 - fixed crash when removing channel with active voices (#116)
376 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
377     un-cache the respective sample if it's really not used by any
378     sampler engine anymore
379     - re-cache samples in case they were changed by an instrument editor,
380     e.g. when a sample was added while playing (#82)
381 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
382     same time stamp as the voice's note-on event and occured both in the
383     same audio fragment cycle (fixes bug #112)
384 persson 1858 - added support for the "fine tune" and "pitch bend range"
385     instrument-level gig parameters
386     - fixed minor artifacts in pitch bend handling
387 schoenebeck 1860 - added support for GS Reset SysEx message
388 persson 1862 - allow gig files to use unlimited downward pitch shifting
389     - added a limit check for upward pitch shifting
390 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
391     note was silent
392 persson 1923 - fixed crash happening when a pitch bend event arrived at the
393     same time a new instrument was loading
394 persson 1644
395 schoenebeck 1687 * LSCP server:
396     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
397     react on MIDI data arriving on certain sampler channels (so far only
398     Note-On and Note-Off events are sent via this LSCP event)
399 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
400     react on MIDI data arriving on certain MIDI input devices (so far only
401     Note-On and Note-Off events are sent via this LSCP event)
402 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
403     SET DB_INSTRUMENT FILE_PATH
404 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
405     frontends to send MIDI messages to specific sampler channel
406     - added two additional fields to GET FILE INSTRUMENT INFO command -
407     KEY_BINDINGS and KEYSWITCH_BINDINGS
408 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
409     was incorrect
410 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
411 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
412     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
413     be triggered respectively
414     - added new LSCP command "SET STREAMS" to globally alter the maximum
415     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
416     which will be triggered respectively
417 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
418     a gigedit file dialog is opened)
419 iliev 1848 - close all connections when LSCPServer is deleted
420 iliev 1882 - hard close of all sockets on exit
421 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
422     driver
423 schoenebeck 1687
424 iliev 1761 * Bug fixes:
425     - fixed a crash which occurs when removing a sampler channel waiting
426     to start instrument loading after another channel
427 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
428     instrument loading in progress (bug #113)
429 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
430     instrument with PERSISTENT load mode
431 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
432     - fixed memory leaks when issuing the following LSCP commands:

434     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
435     GET MIDI_INPUT_DRIVER INFO
436     GET MIDI_INPUT_DRIVER_PARAMETER INFO
437     - fixed possible compilation error when sqlite is not present
438 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
439 iliev 1847 - fixed crash when changing the audio output device of a sampler
440     channel with loaded instrument and start playing notes
441 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
442 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
443     PowerPC, which probably could cause crashes on that platform
444 persson 1889 - fixed a memory management error which could cause a crash when a
445     plugin was unloaded
446 persson 1896 - bugfix: two private structs had the same name, which could cause
447     problems if the linker chose the wrong constructor
448 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
449     Windows

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