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

284 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
285     a pointer to the launched InstrumentEditor object
286 schoenebeck 1876 - added optional 3rd party user data parameter for following

327     exception when getting parameters from a disconnected device
328 schoenebeck 1599
329 persson 1651 * MIDI driver:
330     - added JACK MIDI driver
331 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously

349     instrument database compilable
350 schoenebeck 1930 - added instrument database support on Windows
351     works with both standalone mode and VST plugin.
352     the instruments DB file is located in
353     %USERPROFILE%\.linuxsampler\instruments.db which allows different
354     databases for each windows user
355     if no DB is present it automatically creates the .linuxsampler subdir
356     and then creates an empty DB

368 schoenebeck 1724 - added support for GM global device volume SysEx message
369 schoenebeck 1762 (can be selected at compile time to either apply globally to the
370     whole sampler [default] or only to the sampler channels that are
371     connected to the respective MIDI input port the SysEx message arrived
372     on)
373 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
374     sometimes wrongly killed in the same buffer, causing no sound to
375     be played
376 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
377     which is usally used to switch a part between chromatic sounds and
378     drumkit sounds (as opposed to their common default setting of MIDI
379     part 10 being a drumkit part and all other ones chromatic parts), in
380     LS however one can switch between the first 16 MIDI instrument maps
381     defined for the sampler
382 persson 1764 - made it possible to create multiple sample channels even if the
383     audio thread isn't running
384 persson 1844 - fixed crash when removing channel with active voices (#116)
385 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
386     un-cache the respective sample if it's really not used by any
387     sampler engine anymore
388     - re-cache samples in case they were changed by an instrument editor,
389     e.g. when a sample was added while playing (#82)
390 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
391     same time stamp as the voice's note-on event and occured both in the
392     same audio fragment cycle (fixes bug #112)
393 persson 1858 - added support for the "fine tune" and "pitch bend range"
394     instrument-level gig parameters
395     - fixed minor artifacts in pitch bend handling
396 schoenebeck 1860 - added support for GS Reset SysEx message
397 persson 1862 - allow gig files to use unlimited downward pitch shifting
398     - added a limit check for upward pitch shifting
399 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
400     note was silent
401 persson 1923 - fixed crash happening when a pitch bend event arrived at the
402     same time a new instrument was loading
403 persson 1644
404 schoenebeck 1687 * LSCP server:
405     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
406     react on MIDI data arriving on certain sampler channels (so far only
407     Note-On and Note-Off events are sent via this LSCP event)
408 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
409     react on MIDI data arriving on certain MIDI input devices (so far only
410     Note-On and Note-Off events are sent via this LSCP event)
411 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
412     SET DB_INSTRUMENT FILE_PATH
413 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
414     frontends to send MIDI messages to specific sampler channel
415     - added two additional fields to GET FILE INSTRUMENT INFO command -
416     KEY_BINDINGS and KEYSWITCH_BINDINGS
417 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
418     was incorrect
419 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
420 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
421     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
422     be triggered respectively
423     - added new LSCP command "SET STREAMS" to globally alter the maximum
424     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
425     which will be triggered respectively
426 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
427     a gigedit file dialog is opened)
428 iliev 1848 - close all connections when LSCPServer is deleted
429 iliev 1882 - hard close of all sockets on exit
430 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
431     driver
432 schoenebeck 1687
433 iliev 1761 * Bug fixes:
434     - fixed a crash which occurs when removing a sampler channel waiting
435     to start instrument loading after another channel
436 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
437     instrument loading in progress (bug #113)
438 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
439     instrument with PERSISTENT load mode
440 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
441     - fixed memory leaks when issuing the following LSCP commands:
442     GET AUDIO_OUTPUT_DRIVER INFO
443     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
444     GET MIDI_INPUT_DRIVER INFO
445     GET MIDI_INPUT_DRIVER_PARAMETER INFO
446     - fixed possible compilation error when sqlite is not present
447 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
448 iliev 1847 - fixed crash when changing the audio output device of a sampler
449     channel with loaded instrument and start playing notes
450 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
451 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
452     PowerPC, which probably could cause crashes on that platform
453 persson 1889 - fixed a memory management error which could cause a crash when a
454     plugin was unloaded
455 persson 1896 - bugfix: two private structs had the same name, which could cause
456     problems if the linker chose the wrong constructor
457 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
458     Windows
459 iliev 1761
460    
461 schoenebeck 1560 Version 0.5.1 (6 December 2007)
462 schoenebeck 1454
463     * packaging changes:
464     - added autoconf checks for pthread library
465     - added autoconf check for pthread bug found on certain NPTL-enabled
466     glibc versions (see Gentoo bug report #194076)
467 senoner 1502 - added autoconf checks for MS Windows
468 schoenebeck 1454
469 persson 1455 * general changes:
470     - bugfix: the thread used by an editor plugin didn't die when the
471     editor closed
472 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
473     out all the space. operator--() did not apply size_mask after
474     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
475     order to avoid problems with the _NonVolatileReader functions.
476     - bugfix: Stream.h: added a missing divide by BytesPerSample in
477     GetWriteSpace(). Since this function is currently only used in
478     the stream's qsort() compare function, it didn't trigger any
479     bugs.
480     - Resampler.h, Synthesizer.h: cubic interpolation now works in
481     24bit mode too. Faster method to read 24bit words on little
482     endian machines (x86): replaced 3 byte reads + shifts with a 1
483     unaligned 32bit read and shift
484     - experimental support for MS Windows (MIDI input via MME, AUDIO
485     output via ASIO)
486     - made handling of SIGINT signal (Ctrl-C) a bit more robust
487 iliev 1541 - support for monitoring the total number of active disk streams
488     (new LSCP commands: GET TOTAL_STREAM_COUNT,
489     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
490 persson 1455
491 senoner 1500 * AUDIO driver:
492 persson 1534 - added Windows ASIO low latency audio driver
493 senoner 1500
494 senoner 1485 * MIDI driver:
495 schoenebeck 1495 - added MME Windows MIDI driver
496 senoner 1485
497 schoenebeck 1471 * LSCP server:
498     - added support for Windows style path / filenames, however with
499     forward slash path separators instead of backslash
500     (i.e. "C:/foo/bar.gig")
501 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
502     apostrophes as well
503 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
504     "LIST FILE INSTRUMENTS <file>" and
505     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
506     about an arbitrary instrument file on the system where the sampler is
507     running on
508 schoenebeck 1471
509 schoenebeck 1424 Version 0.5.0 (15 October 2007)
510 schoenebeck 947
511 schoenebeck 1065 * packaging changes:
512 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
513     API header files anymore
514 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
515     the Doxygen API documentation (explicitly listed in Doxyfile.in)
516 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
517     capable to execute our autoconf environment, thus no need anymore
518     to maintain the compile time configuration file (osx/version.h) for
519     OSX manually (patch by Toshi Nagata)
520 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
521     parameters
522 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
523     C++ API header files, all implementation internal global definitions
524     are now in global_private.h
525     - atomic.h is not exposed to the C++ API anymore
526     - no need to include config.h anymore for using LS's API header files
527     - fixed warnings in API doc generation
528 schoenebeck 1065
529 schoenebeck 947 * general changes:
530     - replaced the old, confusing MIDI program change mechanism by a
531     flexible MIDI instrument mapper which allows to map arbitrary
532 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
533 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
534     loaded on the respective channel when such MIDI program change
535     messages arrive, beside that, each entry allows to define a life-time
536     strategy for the instrument, so the user can define whether the
537     instrument should i.e. be permanently loaded (to be able to switch
538     quickly among sounds) or i.e. loaded just on demand when the
539     respective program change arrives (to safe RAM space), as well as a
540     global volume factor for each entry, so the user can adjust the volume
541     dynamic of his mapped instrument collection without having to modify
542 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
543     MIDI instrument maps and assign each sampler channel individually
544     a certain map, so that i.e. separation of normal instruments and
545     drumkits is possible
546 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
547     MIDI instrument maps, MIDI instruments, FX sends, global volume.
548 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
549     due to a constant size RingBuffer FIFO which is now replaced by a
550     dynamic (unlimited) size std::list FIFO
551 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
552     output channels for being processed by external effect processors
553     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
554     controllers
555 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
556 iliev 1130 - Implemented new, improved notification system
557 schoenebeck 1149 - fixed compilation errors regarding OSX
558     (patch by Toshi Nagata)
559 iliev 1161 - implemented instruments database
560 iliev 1345 - added support for escape sequences to the instruments database
561 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
562     within the sampler's process (by using instrument editor plugins),
563     you'll notice the new "Registered instrument editors:" message on
564 schoenebeck 1407 startup, added a new LSCP command:
565     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
566 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
567     given sampler channel, the plugin path can be overridden at compile
568     time with ./configure --enable-plugin-dir=/some/dir
569 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
570     in the sampler's process to safely edit instruments while playing
571     without a crash (hopefully) by either suspending single regions
572     wherever possible or if unavoidable whole engine(s)
573 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
574     policy and priority on thread level, set a minimum stack size for
575     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
576     threads simply inherited properties of starting thread instead of
577     setting their own policy and priority
578 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
579     main process did not wait for the stack trace process to finish
580     its output
581 persson 1248 - fixed some minor memory leaks
582 schoenebeck 1259 - reenabled assembly features support, at the moment only for
583     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
584 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
585     register, to avoid relocations in the text segment at runtime)
586 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
587 schoenebeck 947
588     * MIDI driver:
589     - dispatch bank select (MSB and LSB) messages
590    
591 schoenebeck 1049 * audio driver:
592     - the ALSA audio output driver parameters now reflect the correct
593     parameter value ranges for the respective selected sound card
594     (patch by Till Wimmer, a bit fixed and extended)
595    
596 persson 951 * Gigasampler format engine:
597     - if a filter is used and EG2 finishes before EG1, let the voice
598     die when EG2 has finished (this fixes a problem with clicks and
599     voice starvation for some gigs)
600 persson 1038 - playback is no longer disabled during instrument loading
601     - all notes playing on a channel that changes its instrument keep
602     playing with the old instrument until they get a note off
603     command
604 persson 1039 - EG fix: a release value of zero could cause noises or crash
605 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
606 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
607     above max sustain level, which means that there is a decay phase
608     even if sustain is 100%
609 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
610     noises or crashes
611 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
612 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
613     supplied to the configure script (fixes #46)
614 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
615     instead of a fix value
616 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
617     127 (solo mode) only kill voices if the respective mode really
618     changed
619 persson 951
620 schoenebeck 1244 * LSCP server:
621     - fixed compile time error for old Bison versions
622     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
623 schoenebeck 1245 - parser now supports extended ASCII character set
624     (up to ASCII code 255, i.e. includes now umlauts and accents)
625     - filename arguments in LSCP commands now allow to use escape
626     sequences, that is directly literal as one of: \', \", \\, \n, \r,
627     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
628     code value like \xf2) (fixes bug #24)
629 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
630     least one of their text-based parameters (i.e. name, description):
631     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
632     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
633     "SET DB_INSTRUMENT_DIRECTORY NAME",
634     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
635     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
636     "FIND DB_INSTRUMENT_DIRECTORIES"
637 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
638     occured, the unexpected character and the actually expected, possible
639     character(s), the latter only if less than 5 possibilities)
640 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
641     settings
642 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
643     of strings were treated as being one string containing commas
644     (fixes #57)
645 schoenebeck 1244
646 iliev 959 * Bug fixes:
647     - fixed crash occurring on certain LSCP scripts (Bug 39)
648 persson 1038 - another thread safety fix for lscp "load engine" and "set
649     channel audio output device"
650 iliev 1283 - fixed a crash which occurs when reassigning the same engine
651     on a sampler channel with connected MIDI device
652 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
653     device connected to a sampler channel to number less then or equal
654     to the index of the port to which the sampler channel is connected.
655 iliev 1296 - The previous bindings were not been disconnected when altering
656     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
657     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
658 iliev 1297 - The active stream/voice count statistic was incorrect.
659 iliev 1298 - notification events were not been sent for some sampler
660     channel changes
661 iliev 1305 - added default min and max values to restrict the number of allowed
662     audio output channels and MIDI input ports
663 iliev 1306 - the connection to the PCM interface is now closed when destroying
664     an audio output device
665 schoenebeck 1332 - files with slash in their path or filename could not be loaded
666 iliev 959
667 schoenebeck 1221 * test cases:
668     - updated and fixed (haven't been touched in a while)
669    
670 schoenebeck 937 Version 0.4.0 (24 November 2006)
671 persson 696
672 schoenebeck 697 * packaging changes:
673 capela 868 - changed deprecated copyright attribute to license; added ldconfig
674     to post-(un)install steps; added devel package for liblinuxsampler;
675     to linuxsampler.spec (RPM)
676 schoenebeck 697 - install necessary development header files for allowing 3rd party
677     applications to link against liblinuxsampler
678     - liblinuxsampler's API documentation can be generated with 'make docs'
679     (Doxygen required)
680 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
681     implementation (currently either an integer math solution or a
682     di-harmonic approximation), automatic detection can be overriden
683     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
684     configure script argument though (mandatory for cross-compilation)
685 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
686     provided some on his own (as CXXFLAGS)
687 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
688     messages
689 schoenebeck 852 - added compile time options to allow disabling the various audio and
690     MIDI drivers
691 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
692     (patch by Ebrahim Mayat)
693 schoenebeck 697
694 persson 696 * Gigasampler format engine:
695 schoenebeck 738 - extensive synthesis optimization
696     (reimplementation of EGs and LFO(s), removed synthesis parameter
697     prerendering and the synthesis parameter matrix in general, splitting
698     each audio fragment into subfragments now where each subfragment uses
699 persson 830 constant pitch and filter coefficients. The volume coefficient is
700     linearly interpolated inside a subfragment, unless
701     --disable-interpolate-volume is set.)
702 persson 696 - fine tuning of the EG modulation parameters
703 persson 729 - improved filter cutoff calculation by adding support for the
704     following gig parameters: Cutoff freq (used when no cutoff
705     controller is defined), Control invert, Minimum cutoff, Velocity
706 persson 791 curve and Velocity range. The keyboard tracking now scales
707     cutoff frequency instead of resonance.
708 persson 877 - added support for gig parameter Resonance.
709 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
710 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
711     which can be overridden with --enable-global-attenuation
712 persson 783 - EG fixes: made the length of "attack hold" stage more
713     accurate. Release stage can now start before attack stage
714 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
715     time now has a minimal value to prevent clicks.
716 persson 799 - fixed pitch changes larger than one octave
717 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
718     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
719     all modes can be altered via standard GM messages, that is CC5 for
720     altering portamento time, CC65 for enabling / disabling portamento
721     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
722 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
723     parameter) and crossfade
724 persson 831 - added support for the "attenuation controller threshold" gig
725     parameter
726 persson 832 - added smoothing of volume changes caused by control change
727     messages
728 persson 865 - sample loop parameters are now taken from the DimensionRegion
729     instead of the wave chunk
730     - fixed keyswitching for v3 gigs with a number of keyswitch splits
731     not equal to a power of two
732 persson 877 - reimplementation of the filter algorithm. The new filter is more
733     accurate and supports all gig filter types, including bandreject
734     and lowpass turbo.
735 persson 903 - real support for 24 bit samples - samples are not truncated to
736     16 bits anymore
737     - support for aftertouch (channel pressure, not polyphonic
738     aftertouch)
739 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
740     amplifying from 0)
741 persson 696
742 schoenebeck 711 * LSCP server:
743     - fixed application exit on broken pipe error (fixes bug #20)
744 iliev 793 - fixed the notification messages delay due to lack of
745     network activity (fixes bug #26)
746 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
747     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
748 schoenebeck 711
749 schoenebeck 838 * audio driver:
750     - added aRts audio output driver (by no means RT safe)
751    
752 schoenebeck 775 * MIDI driver:
753     - fixed legacy sysex code which caused dispatching of MIDI SysEx
754     messages several times instead of once
755 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
756     for events (i.e. for offline rendering based MIDI drivers)
757 persson 922 - added checks for bad MIDI data
758 schoenebeck 775
759 schoenebeck 900 * linuxsampler application:
760     - show available sampler engine types on startup
761    
762 schoenebeck 705 * general changes:
763     - support for muting sampler channels and solo mode of the same, two new
764     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
765     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
766     introduced for this, the behavior is the same like on a mixer console
767 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
768     --enable-process-muted-channels which can be used to enable the
769     processing of muted channels.
770 iliev 777 - support for sostenuto pedal
771 iliev 779 - support for monitoring the total number of active voices
772 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
773     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
774 persson 835 - fixed some memory management errors
775 persson 841 - fixed some concurrency problems that could lead to crashes when
776     LSCP commands were executed
777 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
778     sampler channel (fixes bug #36)
779 schoenebeck 705
780 schoenebeck 692 Version 0.3.3 (15 July 2005)
781 schoenebeck 686
782     * packaging changes:
783     - fixed compilation with gcc 4.0
784    
785 schoenebeck 687 * Gigasampler format engine:
786     - LFO preprocessing was performed even though the respective LFO was
787     disabled by the instrument patch (minor efficiency fix)
788 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
789     for volume ramp downs in the same fragment (needed for current voice
790     stealing implementation) then simply inform the user with a warning
791     about possible click sounds and reduce the volume ramp down
792     appropriately instead of cancelling the audio device connection
793 schoenebeck 687
794 schoenebeck 677 Version 0.3.2 (24 June 2005)
795 schoenebeck 609
796     * packaging changes:
797     - updated autotools build files to compile on OS X
798     (conditional compilation of CoreMIDI and MidiShare drivers)
799 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
800     './configure --disable-asm' (definitely not recommended)
801 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
802     - require automake (>= 1.5) for 'make -f Makefile.cvs'
803     (due to 'dist-bzip2' automake option)
804 schoenebeck 649
805     * Gigasampler format engine:
806     - support for the gig parameters for "release velocity response" curves
807     - fine tuning of the EGADSR envelope
808     - volume of release triggered samples now depends on note-on velocity,
809     note length and gig parameter "release trigger decay" instead of
810     note-off velocity.
811 schoenebeck 663 - revised voice stealing
812     (fixes crash and endless loop caused by voice stealing)
813 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
814 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
815     instead of when the respective voice is actually launched
816     (fixes undefined behavior if stolen voices belonged to a key group -
817     this case was followed by a "killed voice survived" error message)
818 schoenebeck 669 - fixed minor issue with null/silence samples
819     (those stole voices even though they don't need a voice at all which
820     resulted in "voice stealing didn't work out" messages)
821 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
822     instrument or audio output device change
823 schoenebeck 654
824 schoenebeck 620 * LSCP server:
825 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
826 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
827 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
828 schoenebeck 609
829 schoenebeck 668 * linuxsampler application:
830     - added command line parameters --lscp-addr and --lscp-port to override
831     default IP address and port of LSCP server
832    
833 schoenebeck 579 Version 0.3.1 (24 May 2005)
834    
835     * initial release
