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

34     note (in this implementation of the sampler its simply hard routed to
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)

192 schoenebeck 1599
193 schoenebeck 1639 * packaging changes:

212 schoenebeck 1639
213 schoenebeck 1601 * general changes:
214     - bugfix: on some POSIX systems instrument editor plugins refused to

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

266 iliev 1829 - added (experimental) CoreAudio driver
267 persson 1888 - applied old fixes to the ASIO driver that were included in the
268     previous binary release but accidentally never committed to CVS
269     (fixes #117)
270 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
271     win64)
272 persson 1895 - VST: added support for sample rate and buffer size changes

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

306 persson 1908 - work-around for missing fnmatch function on Windows to make
307     instrument database compilable
308 schoenebeck 1930 - added instrument database support on Windows
309     works with both standalone mode and VST plugin.
310     the instruments DB file is located in
311     %USERPROFILE%\.linuxsampler\instruments.db which allows different
312     databases for each windows user
313     if no DB is present it automatically creates the .linuxsampler subdir
314     and then creates an empty DB
315 persson 1943 - fixed recursive import, which was broken on Windows
316 iliev 1603
317 persson 1644 * Gigasampler format engine:
318     - fixed a memory leak that could happen when a channel was deleted
319     while notes were playing
320 persson 1646 - made it possible to load an instrument even if the audio thread
321     isn't running
322 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
323     enough for piano gigs with pedal noise samples
324 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
325     respective FX send MIDI controller was used
326 schoenebeck 1724 - added support for GM global device volume SysEx message
327 schoenebeck 1762 (can be selected at compile time to either apply globally to the
328     whole sampler [default] or only to the sampler channels that are
329     connected to the respective MIDI input port the SysEx message arrived
330     on)
331 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
332     sometimes wrongly killed in the same buffer, causing no sound to
333     be played
334 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
335     which is usally used to switch a part between chromatic sounds and
336     drumkit sounds (as opposed to their common default setting of MIDI
337     part 10 being a drumkit part and all other ones chromatic parts), in
338     LS however one can switch between the first 16 MIDI instrument maps
339     defined for the sampler
340 persson 1764 - made it possible to create multiple sample channels even if the
341     audio thread isn't running
342 persson 1844 - fixed crash when removing channel with active voices (#116)
343 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
344     un-cache the respective sample if it's really not used by any
345     sampler engine anymore
346     - re-cache samples in case they were changed by an instrument editor,
347     e.g. when a sample was added while playing (#82)
348 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
349     same time stamp as the voice's note-on event and occured both in the
350     same audio fragment cycle (fixes bug #112)
351 persson 1858 - added support for the "fine tune" and "pitch bend range"
352     instrument-level gig parameters
353     - fixed minor artifacts in pitch bend handling
354 schoenebeck 1860 - added support for GS Reset SysEx message
355 persson 1862 - allow gig files to use unlimited downward pitch shifting
356     - added a limit check for upward pitch shifting
357 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
358     note was silent
359 persson 1923 - fixed crash happening when a pitch bend event arrived at the
360     same time a new instrument was loading
361 persson 1644
362 schoenebeck 1687 * LSCP server:
363     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
364     react on MIDI data arriving on certain sampler channels (so far only
365     Note-On and Note-Off events are sent via this LSCP event)
366 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
367     react on MIDI data arriving on certain MIDI input devices (so far only
368     Note-On and Note-Off events are sent via this LSCP event)
369 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
370     SET DB_INSTRUMENT FILE_PATH
371 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
372     frontends to send MIDI messages to specific sampler channel
373     - added two additional fields to GET FILE INSTRUMENT INFO command -
374     KEY_BINDINGS and KEYSWITCH_BINDINGS
375 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
376     was incorrect
377 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
378 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
379     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
380     be triggered respectively
381     - added new LSCP command "SET STREAMS" to globally alter the maximum
382     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
383     which will be triggered respectively
384 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
385     a gigedit file dialog is opened)
386 iliev 1848 - close all connections when LSCPServer is deleted
387 iliev 1882 - hard close of all sockets on exit
388 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
389     driver
390 schoenebeck 1687
391 iliev 1761 * Bug fixes:
392     - fixed a crash which occurs when removing a sampler channel waiting
393     to start instrument loading after another channel
394 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
395     instrument loading in progress (bug #113)
396 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
397     instrument with PERSISTENT load mode
398 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
399     - fixed memory leaks when issuing the following LSCP commands:
400     GET AUDIO_OUTPUT_DRIVER INFO
401     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
402     GET MIDI_INPUT_DRIVER INFO
403     GET MIDI_INPUT_DRIVER_PARAMETER INFO
404     - fixed possible compilation error when sqlite is not present
405 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
406 iliev 1847 - fixed crash when changing the audio output device of a sampler
407     channel with loaded instrument and start playing notes
408 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
409 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
410     PowerPC, which probably could cause crashes on that platform
411 persson 1889 - fixed a memory management error which could cause a crash when a
412     plugin was unloaded
413 persson 1896 - bugfix: two private structs had the same name, which could cause
414     problems if the linker chose the wrong constructor
415 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
416     Windows

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