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

208 schoenebeck 1599
209 schoenebeck 1639 * packaging changes:
210     - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

228 schoenebeck 1639
229 schoenebeck 1601 * general changes:
230     - bugfix: on some POSIX systems instrument editor plugins refused to

242 schoenebeck 1653 - be verbose on DLL load errors (on Linux)
243 schoenebeck 1681 - fixed di-harmonic triangle LFO implementation (this LFO implementation

255 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
256     be switched on by command line option "--stacktrace" (the automatic
257     stacktrace mechanism seems to be broken on most systems at the moment)
258 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
259     a pointer to the launched InstrumentEditor object
260 schoenebeck 1876 - added optional 3rd party user data parameter for following
261     liblinuxsampler C++ API methods: InstrumentEditor::Main(),
262     InstrumentEditor::Launch(),

264 persson 1887 - theoretical fix: made SynchronizedConfig follow C++0x memory
265     model more strictly
266 persson 1895 - fixes for using large audio device buffers
267 persson 1951 - Windows: add the installation directory to the DLL search path

272     - removed the nonsense audio channel constraint (which was hard coded to
273     max. 100 audio channels) for most audio drivers
274 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
275     opposed to the LSCP specs
276 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
277     reflected the wrong value
278 persson 1644 - fixed a memory management bug in ASIO driver
279 persson 1748 - Makefile fix: JACK_CFLAGS wasn't used

281 persson 1748 jack_client_new
282 iliev 1829 - added (experimental) CoreAudio driver
283 persson 1888 - applied old fixes to the ASIO driver that were included in the
284     previous binary release but accidentally never committed to CVS
285     (fixes #117)
286 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
287     win64)
288 persson 1895 - VST: added support for sample rate and buffer size changes
289     - VST: close editor (Fantasia) when the VST is removed

298     AudioChannel::CopyTo() methods using GCC vector exensions
299     (if available)
300 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
301     exception when getting parameters from a disconnected device
302 schoenebeck 1599
303 persson 1651 * MIDI driver:
304     - added JACK MIDI driver
305 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously

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

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

417     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
418     GET MIDI_INPUT_DRIVER INFO
419     GET MIDI_INPUT_DRIVER_PARAMETER INFO
420     - fixed possible compilation error when sqlite is not present
421 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
422 iliev 1847 - fixed crash when changing the audio output device of a sampler
423     channel with loaded instrument and start playing notes
424 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
425 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
426     PowerPC, which probably could cause crashes on that platform
427 persson 1889 - fixed a memory management error which could cause a crash when a
428     plugin was unloaded
429 persson 1896 - bugfix: two private structs had the same name, which could cause
430     problems if the linker chose the wrong constructor
431 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
432     Windows

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