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

21 persson 2086
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
27 schoenebeck 2053 - Introduced support for optional environment variable

35     the 1st effect send of the sampler channel, no matter what the actual
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
39     the 2nd effect send of the sampler channel, no matter what the actual
40     effect type is)

221     after MIDI/audio device creation failure
222 iliev 2012

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

244 schoenebeck 1639
245 schoenebeck 1601 * general changes:
246     - bugfix: on some POSIX systems instrument editor plugins refused to
247     load as we used a non-portable Linux specific struct field
248     (fixes bug #70, patch by Ronald Baljeu)
249 schoenebeck 1602 - fixed endless loop which occured when loading an instrument editor
250     plugin DLL on Windows systems failed

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

297 persson 1748 jack_client_new
298 iliev 1829 - added (experimental) CoreAudio driver
299 persson 1888 - applied old fixes to the ASIO driver that were included in the
300     previous binary release but accidentally never committed to CVS
301     (fixes #117)
302 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
303     win64)
304 persson 1895 - VST: added support for sample rate and buffer size changes
305     - VST: close editor (Fantasia) when the VST is removed

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

323     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
324 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
325 persson 1887 CoreMidi or AU
326 persson 1889 - fixed mingw-w64 compilation error in MME driver

333     to the instruments database
334 iliev 1727 - added support for handling lost files in the instruments database
335 iliev 1781 - Implemented option for adding instruments in separate directories
336     in the instruments database
337     (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
338 persson 1908 - work-around for missing fnmatch function on Windows to make
339     instrument database compilable
340 schoenebeck 1930 - added instrument database support on Windows
341     works with both standalone mode and VST plugin.
342     the instruments DB file is located in
343     %USERPROFILE%\.linuxsampler\instruments.db which allows different
344     databases for each windows user
345     if no DB is present it automatically creates the .linuxsampler subdir
346     and then creates an empty DB
347 persson 1943 - fixed recursive import, which was broken on Windows
348 iliev 1603
349 persson 1644 * Gigasampler format engine:
350     - fixed a memory leak that could happen when a channel was deleted
351     while notes were playing
352 persson 1646 - made it possible to load an instrument even if the audio thread
353     isn't running
354 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
355     enough for piano gigs with pedal noise samples
356 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
357     respective FX send MIDI controller was used
358 schoenebeck 1724 - added support for GM global device volume SysEx message
359 schoenebeck 1762 (can be selected at compile time to either apply globally to the
360     whole sampler [default] or only to the sampler channels that are
361     connected to the respective MIDI input port the SysEx message arrived
362     on)
363 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
364     sometimes wrongly killed in the same buffer, causing no sound to
365     be played
366 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
367     which is usally used to switch a part between chromatic sounds and
368     drumkit sounds (as opposed to their common default setting of MIDI
369     part 10 being a drumkit part and all other ones chromatic parts), in
370     LS however one can switch between the first 16 MIDI instrument maps
371     defined for the sampler
372 persson 1764 - made it possible to create multiple sample channels even if the
373     audio thread isn't running
374 persson 1844 - fixed crash when removing channel with active voices (#116)
375 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
376     un-cache the respective sample if it's really not used by any
377     sampler engine anymore
378     - re-cache samples in case they were changed by an instrument editor,
379     e.g. when a sample was added while playing (#82)
380 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
381     same time stamp as the voice's note-on event and occured both in the
382     same audio fragment cycle (fixes bug #112)
383 persson 1858 - added support for the "fine tune" and "pitch bend range"
384     instrument-level gig parameters
385     - fixed minor artifacts in pitch bend handling
386 schoenebeck 1860 - added support for GS Reset SysEx message
387 persson 1862 - allow gig files to use unlimited downward pitch shifting
388     - added a limit check for upward pitch shifting
389 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
390     note was silent
391 persson 1923 - fixed crash happening when a pitch bend event arrived at the
392     same time a new instrument was loading
393 persson 1644
394 schoenebeck 1687 * LSCP server:
395     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
396     react on MIDI data arriving on certain sampler channels (so far only
397     Note-On and Note-Off events are sent via this LSCP event)
398 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
399     react on MIDI data arriving on certain MIDI input devices (so far only
400     Note-On and Note-Off events are sent via this LSCP event)
401 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
402     SET DB_INSTRUMENT FILE_PATH
403 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
404     frontends to send MIDI messages to specific sampler channel
405     - added two additional fields to GET FILE INSTRUMENT INFO command -
406     KEY_BINDINGS and KEYSWITCH_BINDINGS
407 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
408     was incorrect
409 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
410 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
411     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
412     be triggered respectively
413     - added new LSCP command "SET STREAMS" to globally alter the maximum
414     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
415     which will be triggered respectively
416 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
417     a gigedit file dialog is opened)
418 iliev 1848 - close all connections when LSCPServer is deleted
419 iliev 1882 - hard close of all sockets on exit
420 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
421     driver
422 schoenebeck 1687
423 iliev 1761 * Bug fixes:
424     - fixed a crash which occurs when removing a sampler channel waiting
425     to start instrument loading after another channel
426 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
427     instrument loading in progress (bug #113)
428 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
429     instrument with PERSISTENT load mode
430 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
431     - fixed memory leaks when issuing the following LSCP commands:

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

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