9     - Mac OS X: fixed building outside source directory
10     - made sure all source files for hostplugins are included when
11     doing "make dist"
12     - removed empty directories left from the cvs to svn migration
13 persson 2185 - fixed compilation with gcc 4.6.1
14 persson 2203 - another "make dist" fix, for the LV2 plugin
15 persson 2185 - made --enable-pthread-testcancel default on Mac OS X
16 persson 2197 - minor Makefile fix for building lscpparser when build and source
17     directories are separate

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

219     after MIDI/audio device creation failure
220 iliev 2012

222 schoenebeck 1599
223 schoenebeck 1639 * packaging changes:
224     - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

242 schoenebeck 1639
243 schoenebeck 1601 * general changes:
244     - bugfix: on some POSIX systems instrument editor plugins refused to

269 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
270     be switched on by command line option "--stacktrace" (the automatic
271     stacktrace mechanism seems to be broken on most systems at the moment)
272 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
273     a pointer to the launched InstrumentEditor object
274 schoenebeck 1876 - added optional 3rd party user data parameter for following
275     liblinuxsampler C++ API methods: InstrumentEditor::Main(),
276     InstrumentEditor::Launch(),
277     InstrumentManager::LaunchInstrumentEditor()
278 persson 1887 - theoretical fix: made SynchronizedConfig follow C++0x memory
279     model more strictly
280 persson 1895 - fixes for using large audio device buffers
281 persson 1951 - Windows: add the installation directory to the DLL search path
282     when loading an editor plugin (solves problems with VST and
283     gigedit on systems with other GTK versions installed)
284 schoenebeck 1601

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

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

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

336 persson 1908 - work-around for missing fnmatch function on Windows to make
337     instrument database compilable
338 schoenebeck 1930 - added instrument database support on Windows
339     works with both standalone mode and VST plugin.
340     the instruments DB file is located in
341     %USERPROFILE%\.linuxsampler\instruments.db which allows different
342     databases for each windows user
343     if no DB is present it automatically creates the .linuxsampler subdir
344     and then creates an empty DB
345 persson 1943 - fixed recursive import, which was broken on Windows
346 iliev 1603
347 persson 1644 * Gigasampler format engine:
348     - fixed a memory leak that could happen when a channel was deleted
349     while notes were playing
350 persson 1646 - made it possible to load an instrument even if the audio thread
351     isn't running
352 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
353     enough for piano gigs with pedal noise samples
354 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
355     respective FX send MIDI controller was used
356 schoenebeck 1724 - added support for GM global device volume SysEx message
357 schoenebeck 1762 (can be selected at compile time to either apply globally to the
358     whole sampler [default] or only to the sampler channels that are
359     connected to the respective MIDI input port the SysEx message arrived
360     on)
361 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
362     sometimes wrongly killed in the same buffer, causing no sound to
363     be played
364 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
365     which is usally used to switch a part between chromatic sounds and
366     drumkit sounds (as opposed to their common default setting of MIDI
367     part 10 being a drumkit part and all other ones chromatic parts), in
368     LS however one can switch between the first 16 MIDI instrument maps
369     defined for the sampler
370 persson 1764 - made it possible to create multiple sample channels even if the
371     audio thread isn't running
372 persson 1844 - fixed crash when removing channel with active voices (#116)
373 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
374     un-cache the respective sample if it's really not used by any
375     sampler engine anymore
376     - re-cache samples in case they were changed by an instrument editor,
377     e.g. when a sample was added while playing (#82)
378 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
379     same time stamp as the voice's note-on event and occured both in the
380     same audio fragment cycle (fixes bug #112)
381 persson 1858 - added support for the "fine tune" and "pitch bend range"
382     instrument-level gig parameters
383     - fixed minor artifacts in pitch bend handling

387 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
388     note was silent
389 persson 1923 - fixed crash happening when a pitch bend event arrived at the
390     same time a new instrument was loading
391 persson 1644
392 schoenebeck 1687 * LSCP server:
393     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
394     react on MIDI data arriving on certain sampler channels (so far only
395     Note-On and Note-Off events are sent via this LSCP event)
396 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
397     react on MIDI data arriving on certain MIDI input devices (so far only
398     Note-On and Note-Off events are sent via this LSCP event)
399 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
400     SET DB_INSTRUMENT FILE_PATH
401 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
402     frontends to send MIDI messages to specific sampler channel
403     - added two additional fields to GET FILE INSTRUMENT INFO command -
404     KEY_BINDINGS and KEYSWITCH_BINDINGS
405 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
406     was incorrect
407 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
408 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
409     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
410     be triggered respectively
411     - added new LSCP command "SET STREAMS" to globally alter the maximum
412     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
413     which will be triggered respectively
414 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
415     a gigedit file dialog is opened)
416 iliev 1848 - close all connections when LSCPServer is deleted
417 iliev 1882 - hard close of all sockets on exit
418 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
419     driver
420 schoenebeck 1687
421 iliev 1761 * Bug fixes:
422     - fixed a crash which occurs when removing a sampler channel waiting
423     to start instrument loading after another channel
424 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
425     instrument loading in progress (bug #113)
426 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
427     instrument with PERSISTENT load mode
428 iliev 1835 - fixed possible iterator invalidations when resetting the sampler

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

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