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

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

241 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
242     be switched on by command line option "--stacktrace" (the automatic
243     stacktrace mechanism seems to be broken on most systems at the moment)
244 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
245     a pointer to the launched InstrumentEditor object
246 schoenebeck 1876 - added optional 3rd party user data parameter for following
247     liblinuxsampler C++ API methods: InstrumentEditor::Main(),
248     InstrumentEditor::Launch(),

268 iliev 1829 - added (experimental) CoreAudio driver
269 persson 1888 - applied old fixes to the ASIO driver that were included in the
270     previous binary release but accidentally never committed to CVS
271     (fixes #117)
272 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
273     win64)

284     AudioChannel::CopyTo() methods using GCC vector exensions
285     (if available)
286 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
287     exception when getting parameters from a disconnected device
288 schoenebeck 1599
289 persson 1651 * MIDI driver:
290     - added JACK MIDI driver
291 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously

308 persson 1908 - work-around for missing fnmatch function on Windows to make
309     instrument database compilable
310 schoenebeck 1930 - added instrument database support on Windows
311     works with both standalone mode and VST plugin.
312     the instruments DB file is located in
313     %USERPROFILE%\.linuxsampler\instruments.db which allows different
314     databases for each windows user
315     if no DB is present it automatically creates the .linuxsampler subdir
316     and then creates an empty DB
317 persson 1943 - fixed recursive import, which was broken on Windows
318 iliev 1603
319 persson 1644 * Gigasampler format engine:
320     - fixed a memory leak that could happen when a channel was deleted
321     while notes were playing
322 persson 1646 - made it possible to load an instrument even if the audio thread
323     isn't running
324 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
325     enough for piano gigs with pedal noise samples
326 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
327     respective FX send MIDI controller was used
328 schoenebeck 1724 - added support for GM global device volume SysEx message
329 schoenebeck 1762 (can be selected at compile time to either apply globally to the
330     whole sampler [default] or only to the sampler channels that are
331     connected to the respective MIDI input port the SysEx message arrived
332     on)
333 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
334     sometimes wrongly killed in the same buffer, causing no sound to
335     be played
336 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
337     which is usally used to switch a part between chromatic sounds and
338     drumkit sounds (as opposed to their common default setting of MIDI
339     part 10 being a drumkit part and all other ones chromatic parts), in
340     LS however one can switch between the first 16 MIDI instrument maps
341     defined for the sampler
342 persson 1764 - made it possible to create multiple sample channels even if the
343     audio thread isn't running
344 persson 1844 - fixed crash when removing channel with active voices (#116)
345 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
346     un-cache the respective sample if it's really not used by any
347     sampler engine anymore
348     - re-cache samples in case they were changed by an instrument editor,
349     e.g. when a sample was added while playing (#82)
350 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
351     same time stamp as the voice's note-on event and occured both in the
352     same audio fragment cycle (fixes bug #112)
353 persson 1858 - added support for the "fine tune" and "pitch bend range"
354     instrument-level gig parameters
355     - fixed minor artifacts in pitch bend handling
356 schoenebeck 1860 - added support for GS Reset SysEx message
357 persson 1862 - allow gig files to use unlimited downward pitch shifting
358     - added a limit check for upward pitch shifting
359 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
360     note was silent
361 persson 1923 - fixed crash happening when a pitch bend event arrived at the
362     same time a new instrument was loading
363 persson 1644
364 schoenebeck 1687 * LSCP server:
365     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
366     react on MIDI data arriving on certain sampler channels (so far only
367     Note-On and Note-Off events are sent via this LSCP event)
368 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
369     react on MIDI data arriving on certain MIDI input devices (so far only
370     Note-On and Note-Off events are sent via this LSCP event)
371 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
372     SET DB_INSTRUMENT FILE_PATH
373 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
374     frontends to send MIDI messages to specific sampler channel
375     - added two additional fields to GET FILE INSTRUMENT INFO command -
376     KEY_BINDINGS and KEYSWITCH_BINDINGS
377 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
378     was incorrect
379 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
380 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
381     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
382     be triggered respectively
383     - added new LSCP command "SET STREAMS" to globally alter the maximum
384     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
385     which will be triggered respectively
386 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
387     a gigedit file dialog is opened)
388 iliev 1848 - close all connections when LSCPServer is deleted
389 iliev 1882 - hard close of all sockets on exit
390 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
391     driver
392 schoenebeck 1687
393 iliev 1761 * Bug fixes:
394     - fixed a crash which occurs when removing a sampler channel waiting
395     to start instrument loading after another channel
396 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
397     instrument loading in progress (bug #113)
398 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
399     instrument with PERSISTENT load mode
400 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
401     - fixed memory leaks when issuing the following LSCP commands:
402     GET AUDIO_OUTPUT_DRIVER INFO
403     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
404     GET MIDI_INPUT_DRIVER INFO
405     GET MIDI_INPUT_DRIVER_PARAMETER INFO
406     - fixed possible compilation error when sqlite is not present
407 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
408 iliev 1847 - fixed crash when changing the audio output device of a sampler
409     channel with loaded instrument and start playing notes
410 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
411 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
412     PowerPC, which probably could cause crashes on that platform
413 persson 1889 - fixed a memory management error which could cause a crash when a
414     plugin was unloaded
415 persson 1896 - bugfix: two private structs had the same name, which could cause
416     problems if the linker chose the wrong constructor
417 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
418     Windows
419 iliev 1761
420    
421 schoenebeck 1560 Version 0.5.1 (6 December 2007)
422 schoenebeck 1454
423     * packaging changes:
424     - added autoconf checks for pthread library
425     - added autoconf check for pthread bug found on certain NPTL-enabled
426     glibc versions (see Gentoo bug report #194076)
427 senoner 1502 - added autoconf checks for MS Windows
428 schoenebeck 1454
429 persson 1455 * general changes:
430     - bugfix: the thread used by an editor plugin didn't die when the
431     editor closed
432 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
433     out all the space. operator--() did not apply size_mask after
434     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
435     order to avoid problems with the _NonVolatileReader functions.
436     - bugfix: Stream.h: added a missing divide by BytesPerSample in
437     GetWriteSpace(). Since this function is currently only used in
438     the stream's qsort() compare function, it didn't trigger any
439     bugs.
440     - Resampler.h, Synthesizer.h: cubic interpolation now works in
441     24bit mode too. Faster method to read 24bit words on little
442     endian machines (x86): replaced 3 byte reads + shifts with a 1
443     unaligned 32bit read and shift
444     - experimental support for MS Windows (MIDI input via MME, AUDIO
445     output via ASIO)
446     - made handling of SIGINT signal (Ctrl-C) a bit more robust
447 iliev 1541 - support for monitoring the total number of active disk streams
448     (new LSCP commands: GET TOTAL_STREAM_COUNT,
449     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
450 persson 1455
451 senoner 1500 * AUDIO driver:
452 persson 1534 - added Windows ASIO low latency audio driver
453 senoner 1500
454 senoner 1485 * MIDI driver:
455 schoenebeck 1495 - added MME Windows MIDI driver
456 senoner 1485
457 schoenebeck 1471 * LSCP server:
458     - added support for Windows style path / filenames, however with
459     forward slash path separators instead of backslash
460     (i.e. "C:/foo/bar.gig")
461 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
462     apostrophes as well
463 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
464     "LIST FILE INSTRUMENTS <file>" and
465     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
466     about an arbitrary instrument file on the system where the sampler is
467     running on
468 schoenebeck 1471
469 schoenebeck 1424 Version 0.5.0 (15 October 2007)
470 schoenebeck 947
471 schoenebeck 1065 * packaging changes:
472 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
473     API header files anymore
474 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
475     the Doxygen API documentation (explicitly listed in Doxyfile.in)
476 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
477     capable to execute our autoconf environment, thus no need anymore
478     to maintain the compile time configuration file (osx/version.h) for
479     OSX manually (patch by Toshi Nagata)
480 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
481     parameters
482 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
483     C++ API header files, all implementation internal global definitions
484     are now in global_private.h
485     - atomic.h is not exposed to the C++ API anymore
486     - no need to include config.h anymore for using LS's API header files
487     - fixed warnings in API doc generation
488 schoenebeck 1065
489 schoenebeck 947 * general changes:
490     - replaced the old, confusing MIDI program change mechanism by a
491     flexible MIDI instrument mapper which allows to map arbitrary
492 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
493 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
494     loaded on the respective channel when such MIDI program change
495     messages arrive, beside that, each entry allows to define a life-time
496     strategy for the instrument, so the user can define whether the
497     instrument should i.e. be permanently loaded (to be able to switch
498     quickly among sounds) or i.e. loaded just on demand when the
499     respective program change arrives (to safe RAM space), as well as a
500     global volume factor for each entry, so the user can adjust the volume
501     dynamic of his mapped instrument collection without having to modify
502 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
503     MIDI instrument maps and assign each sampler channel individually
504     a certain map, so that i.e. separation of normal instruments and
505     drumkits is possible
506 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
507     MIDI instrument maps, MIDI instruments, FX sends, global volume.
508 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
509     due to a constant size RingBuffer FIFO which is now replaced by a
510     dynamic (unlimited) size std::list FIFO
511 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
512     output channels for being processed by external effect processors
513     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
514     controllers
515 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
516 iliev 1130 - Implemented new, improved notification system
517 schoenebeck 1149 - fixed compilation errors regarding OSX
518     (patch by Toshi Nagata)
519 iliev 1161 - implemented instruments database
520 iliev 1345 - added support for escape sequences to the instruments database
521 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
522     within the sampler's process (by using instrument editor plugins),
523     you'll notice the new "Registered instrument editors:" message on
524 schoenebeck 1407 startup, added a new LSCP command:
525     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
526 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
527     given sampler channel, the plugin path can be overridden at compile
528     time with ./configure --enable-plugin-dir=/some/dir
529 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
530     in the sampler's process to safely edit instruments while playing
531     without a crash (hopefully) by either suspending single regions
532     wherever possible or if unavoidable whole engine(s)
533 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
534     policy and priority on thread level, set a minimum stack size for
535     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
536     threads simply inherited properties of starting thread instead of
537     setting their own policy and priority
538 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
539     main process did not wait for the stack trace process to finish
540     its output
541 persson 1248 - fixed some minor memory leaks
542 schoenebeck 1259 - reenabled assembly features support, at the moment only for
543     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
544 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
545     register, to avoid relocations in the text segment at runtime)
546 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
547 schoenebeck 947
548     * MIDI driver:
549     - dispatch bank select (MSB and LSB) messages
550    
551 schoenebeck 1049 * audio driver:
552     - the ALSA audio output driver parameters now reflect the correct
553     parameter value ranges for the respective selected sound card
554     (patch by Till Wimmer, a bit fixed and extended)
555    
556 persson 951 * Gigasampler format engine:
557     - if a filter is used and EG2 finishes before EG1, let the voice
558     die when EG2 has finished (this fixes a problem with clicks and
559     voice starvation for some gigs)
560 persson 1038 - playback is no longer disabled during instrument loading
561     - all notes playing on a channel that changes its instrument keep
562     playing with the old instrument until they get a note off
563     command
564 persson 1039 - EG fix: a release value of zero could cause noises or crash
565 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
566 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
567     above max sustain level, which means that there is a decay phase
568     even if sustain is 100%
569 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
570     noises or crashes
571 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
572 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
573     supplied to the configure script (fixes #46)
574 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
575     instead of a fix value
576 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
577     127 (solo mode) only kill voices if the respective mode really
578     changed
579 persson 951
580 schoenebeck 1244 * LSCP server:
581     - fixed compile time error for old Bison versions
582     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
583 schoenebeck 1245 - parser now supports extended ASCII character set
584     (up to ASCII code 255, i.e. includes now umlauts and accents)
585     - filename arguments in LSCP commands now allow to use escape
586     sequences, that is directly literal as one of: \', \", \\, \n, \r,
587     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
588     code value like \xf2) (fixes bug #24)
589 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
590     least one of their text-based parameters (i.e. name, description):
591     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
592     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
593     "SET DB_INSTRUMENT_DIRECTORY NAME",
594     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
595     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
596     "FIND DB_INSTRUMENT_DIRECTORIES"
597 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
598     occured, the unexpected character and the actually expected, possible
599     character(s), the latter only if less than 5 possibilities)
600 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
601     settings
602 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
603     of strings were treated as being one string containing commas
604     (fixes #57)
605 schoenebeck 1244
606 iliev 959 * Bug fixes:
607     - fixed crash occurring on certain LSCP scripts (Bug 39)
608 persson 1038 - another thread safety fix for lscp "load engine" and "set
609     channel audio output device"
610 iliev 1283 - fixed a crash which occurs when reassigning the same engine
611     on a sampler channel with connected MIDI device
612 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
613     device connected to a sampler channel to number less then or equal
614     to the index of the port to which the sampler channel is connected.
615 iliev 1296 - The previous bindings were not been disconnected when altering
616     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
617     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
618 iliev 1297 - The active stream/voice count statistic was incorrect.
619 iliev 1298 - notification events were not been sent for some sampler
620     channel changes
621 iliev 1305 - added default min and max values to restrict the number of allowed
622     audio output channels and MIDI input ports
623 iliev 1306 - the connection to the PCM interface is now closed when destroying
624     an audio output device
625 schoenebeck 1332 - files with slash in their path or filename could not be loaded
626 iliev 959
627 schoenebeck 1221 * test cases:
628     - updated and fixed (haven't been touched in a while)
629    
630 schoenebeck 937 Version 0.4.0 (24 November 2006)
631 persson 696
632 schoenebeck 697 * packaging changes:
633 capela 868 - changed deprecated copyright attribute to license; added ldconfig
634     to post-(un)install steps; added devel package for liblinuxsampler;
635     to linuxsampler.spec (RPM)
636 schoenebeck 697 - install necessary development header files for allowing 3rd party
637     applications to link against liblinuxsampler
638     - liblinuxsampler's API documentation can be generated with 'make docs'
639     (Doxygen required)
640 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
641     implementation (currently either an integer math solution or a
642     di-harmonic approximation), automatic detection can be overriden
643     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
644     configure script argument though (mandatory for cross-compilation)
645 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
646     provided some on his own (as CXXFLAGS)
647 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
648     messages
649 schoenebeck 852 - added compile time options to allow disabling the various audio and
650     MIDI drivers
651 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
652     (patch by Ebrahim Mayat)
653 schoenebeck 697
654 persson 696 * Gigasampler format engine:
655 schoenebeck 738 - extensive synthesis optimization
656     (reimplementation of EGs and LFO(s), removed synthesis parameter
657     prerendering and the synthesis parameter matrix in general, splitting
658     each audio fragment into subfragments now where each subfragment uses
659 persson 830 constant pitch and filter coefficients. The volume coefficient is
660     linearly interpolated inside a subfragment, unless
661     --disable-interpolate-volume is set.)
662 persson 696 - fine tuning of the EG modulation parameters
663 persson 729 - improved filter cutoff calculation by adding support for the
664     following gig parameters: Cutoff freq (used when no cutoff
665     controller is defined), Control invert, Minimum cutoff, Velocity
666 persson 791 curve and Velocity range. The keyboard tracking now scales
667     cutoff frequency instead of resonance.
668 persson 877 - added support for gig parameter Resonance.
669 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
670 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
671     which can be overridden with --enable-global-attenuation
672 persson 783 - EG fixes: made the length of "attack hold" stage more
673     accurate. Release stage can now start before attack stage
674 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
675     time now has a minimal value to prevent clicks.
676 persson 799 - fixed pitch changes larger than one octave
677 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
678     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
679     all modes can be altered via standard GM messages, that is CC5 for
680     altering portamento time, CC65 for enabling / disabling portamento
681     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
682 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
683     parameter) and crossfade
684 persson 831 - added support for the "attenuation controller threshold" gig
685     parameter
686 persson 832 - added smoothing of volume changes caused by control change
687     messages
688 persson 865 - sample loop parameters are now taken from the DimensionRegion
689     instead of the wave chunk
690     - fixed keyswitching for v3 gigs with a number of keyswitch splits
691     not equal to a power of two
692 persson 877 - reimplementation of the filter algorithm. The new filter is more
693     accurate and supports all gig filter types, including bandreject
694     and lowpass turbo.
695 persson 903 - real support for 24 bit samples - samples are not truncated to
696     16 bits anymore
697     - support for aftertouch (channel pressure, not polyphonic
698     aftertouch)
699 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
700     amplifying from 0)
701 persson 696
702 schoenebeck 711 * LSCP server:
703     - fixed application exit on broken pipe error (fixes bug #20)
704 iliev 793 - fixed the notification messages delay due to lack of
705     network activity (fixes bug #26)
706 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
707     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
708 schoenebeck 711
709 schoenebeck 838 * audio driver:
710     - added aRts audio output driver (by no means RT safe)
711    
712 schoenebeck 775 * MIDI driver:
713     - fixed legacy sysex code which caused dispatching of MIDI SysEx
714     messages several times instead of once
715 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
716     for events (i.e. for offline rendering based MIDI drivers)
717 persson 922 - added checks for bad MIDI data
718 schoenebeck 775
719 schoenebeck 900 * linuxsampler application:
720     - show available sampler engine types on startup
721    
722 schoenebeck 705 * general changes:
723     - support for muting sampler channels and solo mode of the same, two new
724     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
725     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
726     introduced for this, the behavior is the same like on a mixer console
727 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
728     --enable-process-muted-channels which can be used to enable the
729     processing of muted channels.
730 iliev 777 - support for sostenuto pedal
731 iliev 779 - support for monitoring the total number of active voices
732 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
733     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
734 persson 835 - fixed some memory management errors
735 persson 841 - fixed some concurrency problems that could lead to crashes when
736     LSCP commands were executed
737 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
738     sampler channel (fixes bug #36)
739 schoenebeck 705
740 schoenebeck 692 Version 0.3.3 (15 July 2005)
741 schoenebeck 686
742     * packaging changes:
743     - fixed compilation with gcc 4.0
744    
745 schoenebeck 687 * Gigasampler format engine:
746     - LFO preprocessing was performed even though the respective LFO was
747     disabled by the instrument patch (minor efficiency fix)
748 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
749     for volume ramp downs in the same fragment (needed for current voice
750     stealing implementation) then simply inform the user with a warning
751     about possible click sounds and reduce the volume ramp down
752     appropriately instead of cancelling the audio device connection
753 schoenebeck 687
754 schoenebeck 677 Version 0.3.2 (24 June 2005)
755 schoenebeck 609
756     * packaging changes:
757     - updated autotools build files to compile on OS X
758     (conditional compilation of CoreMIDI and MidiShare drivers)
759 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
760     './configure --disable-asm' (definitely not recommended)
761 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
762     - require automake (>= 1.5) for 'make -f Makefile.cvs'
763     (due to 'dist-bzip2' automake option)
764 schoenebeck 649
765     * Gigasampler format engine:
766     - support for the gig parameters for "release velocity response" curves
767     - fine tuning of the EGADSR envelope
768     - volume of release triggered samples now depends on note-on velocity,
769     note length and gig parameter "release trigger decay" instead of
770     note-off velocity.
771 schoenebeck 663 - revised voice stealing
772     (fixes crash and endless loop caused by voice stealing)
773 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
774 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
775     instead of when the respective voice is actually launched
776     (fixes undefined behavior if stolen voices belonged to a key group -
777     this case was followed by a "killed voice survived" error message)
778 schoenebeck 669 - fixed minor issue with null/silence samples
779     (those stole voices even though they don't need a voice at all which
