21 persson 2086
22     * general changes:
23 iliev 2012 - Refactoring: moved the independent code from
24     the Gigasampler format engine to base classes
25 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
26     respective profiling code is currently broken
27 schoenebeck 2053 - Introduced support for optional environment variable

35     the 1st effect send of the sampler channel, no matter what the actual
36     effect type is)
37     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
38     note (in this implementation of the sampler its simply hard routed to

294 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
295     a pointer to the launched InstrumentEditor object
296 schoenebeck 1876 - added optional 3rd party user data parameter for following
297     liblinuxsampler C++ API methods: InstrumentEditor::Main(),
298     InstrumentEditor::Launch(),

361     works with both standalone mode and VST plugin.
362     the instruments DB file is located in
363     %USERPROFILE%\.linuxsampler\instruments.db which allows different

365     if no DB is present it automatically creates the .linuxsampler subdir
366     and then creates an empty DB

368 iliev 1603
369 persson 1644 * Gigasampler format engine:
370     - fixed a memory leak that could happen when a channel was deleted
371     while notes were playing
372 persson 1646 - made it possible to load an instrument even if the audio thread
373     isn't running
374 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
375     enough for piano gigs with pedal noise samples
376 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
377     respective FX send MIDI controller was used
378 schoenebeck 1724 - added support for GM global device volume SysEx message
379 schoenebeck 1762 (can be selected at compile time to either apply globally to the
380     whole sampler [default] or only to the sampler channels that are
381     connected to the respective MIDI input port the SysEx message arrived
382     on)
383 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
384     sometimes wrongly killed in the same buffer, causing no sound to
385     be played
386 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
387     which is usally used to switch a part between chromatic sounds and
388     drumkit sounds (as opposed to their common default setting of MIDI
389     part 10 being a drumkit part and all other ones chromatic parts), in
390     LS however one can switch between the first 16 MIDI instrument maps
391     defined for the sampler
392 persson 1764 - made it possible to create multiple sample channels even if the
393     audio thread isn't running
394 persson 1844 - fixed crash when removing channel with active voices (#116)
395 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
396     un-cache the respective sample if it's really not used by any
397     sampler engine anymore
398     - re-cache samples in case they were changed by an instrument editor,
399     e.g. when a sample was added while playing (#82)
400 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
401     same time stamp as the voice's note-on event and occured both in the
402     same audio fragment cycle (fixes bug #112)
403 persson 1858 - added support for the "fine tune" and "pitch bend range"
404     instrument-level gig parameters
405     - fixed minor artifacts in pitch bend handling
406 schoenebeck 1860 - added support for GS Reset SysEx message
407 persson 1862 - allow gig files to use unlimited downward pitch shifting
408     - added a limit check for upward pitch shifting
409 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
410     note was silent
411 persson 1923 - fixed crash happening when a pitch bend event arrived at the
412     same time a new instrument was loading
413 persson 1644
414 schoenebeck 1687 * LSCP server:
415     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
416     react on MIDI data arriving on certain sampler channels (so far only
417     Note-On and Note-Off events are sent via this LSCP event)
418 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
419     react on MIDI data arriving on certain MIDI input devices (so far only
420     Note-On and Note-Off events are sent via this LSCP event)
421 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
422     SET DB_INSTRUMENT FILE_PATH
423 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
424     frontends to send MIDI messages to specific sampler channel
425     - added two additional fields to GET FILE INSTRUMENT INFO command -
426     KEY_BINDINGS and KEYSWITCH_BINDINGS
427 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
428     was incorrect
429 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
430 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
431     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
432     be triggered respectively
433     - added new LSCP command "SET STREAMS" to globally alter the maximum
434     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
435     which will be triggered respectively
436 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
437     a gigedit file dialog is opened)
438 iliev 1848 - close all connections when LSCPServer is deleted
439 iliev 1882 - hard close of all sockets on exit
440 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
441     driver
442 schoenebeck 1687
443 iliev 1761 * Bug fixes:
444     - fixed a crash which occurs when removing a sampler channel waiting
445     to start instrument loading after another channel
446 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
447     instrument loading in progress (bug #113)
448 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
449     instrument with PERSISTENT load mode
450 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
451     - fixed memory leaks when issuing the following LSCP commands:
452     GET AUDIO_OUTPUT_DRIVER INFO
453     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
454     GET MIDI_INPUT_DRIVER INFO
455     GET MIDI_INPUT_DRIVER_PARAMETER INFO
456     - fixed possible compilation error when sqlite is not present
457 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
458 iliev 1847 - fixed crash when changing the audio output device of a sampler
459     channel with loaded instrument and start playing notes
460 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
461 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
462     PowerPC, which probably could cause crashes on that platform
463 persson 1889 - fixed a memory management error which could cause a crash when a
464     plugin was unloaded
465 persson 1896 - bugfix: two private structs had the same name, which could cause
466     problems if the linker chose the wrong constructor
467 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
468     Windows
469 iliev 1761
470    
471 schoenebeck 1560 Version 0.5.1 (6 December 2007)
472 schoenebeck 1454
473     * packaging changes:
474     - added autoconf checks for pthread library
475     - added autoconf check for pthread bug found on certain NPTL-enabled
476     glibc versions (see Gentoo bug report #194076)
477 senoner 1502 - added autoconf checks for MS Windows
478 schoenebeck 1454
479 persson 1455 * general changes:
480     - bugfix: the thread used by an editor plugin didn't die when the
481     editor closed
482 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
483     out all the space. operator--() did not apply size_mask after
484     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
485     order to avoid problems with the _NonVolatileReader functions.
486     - bugfix: Stream.h: added a missing divide by BytesPerSample in
487     GetWriteSpace(). Since this function is currently only used in
488     the stream's qsort() compare function, it didn't trigger any
489     bugs.
490     - Resampler.h, Synthesizer.h: cubic interpolation now works in
491     24bit mode too. Faster method to read 24bit words on little
492     endian machines (x86): replaced 3 byte reads + shifts with a 1
493     unaligned 32bit read and shift
494     - experimental support for MS Windows (MIDI input via MME, AUDIO
495     output via ASIO)
496     - made handling of SIGINT signal (Ctrl-C) a bit more robust
497 iliev 1541 - support for monitoring the total number of active disk streams
498     (new LSCP commands: GET TOTAL_STREAM_COUNT,
499     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
500 persson 1455
501 senoner 1500 * AUDIO driver:
502 persson 1534 - added Windows ASIO low latency audio driver
503 senoner 1500
504 senoner 1485 * MIDI driver:
505 schoenebeck 1495 - added MME Windows MIDI driver
506 senoner 1485
507 schoenebeck 1471 * LSCP server:
508     - added support for Windows style path / filenames, however with
509     forward slash path separators instead of backslash
510     (i.e. "C:/foo/bar.gig")
511 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
512     apostrophes as well
513 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
514     "LIST FILE INSTRUMENTS <file>" and
515     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
516     about an arbitrary instrument file on the system where the sampler is
517     running on
518 schoenebeck 1471
519 schoenebeck 1424 Version 0.5.0 (15 October 2007)
520 schoenebeck 947
521 schoenebeck 1065 * packaging changes:
522 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
523     API header files anymore
524 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
525     the Doxygen API documentation (explicitly listed in Doxyfile.in)
526 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
527     capable to execute our autoconf environment, thus no need anymore
528     to maintain the compile time configuration file (osx/version.h) for
529     OSX manually (patch by Toshi Nagata)
530 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
531     parameters
532 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
533     C++ API header files, all implementation internal global definitions
534     are now in global_private.h
535     - atomic.h is not exposed to the C++ API anymore
536     - no need to include config.h anymore for using LS's API header files
537     - fixed warnings in API doc generation
538 schoenebeck 1065
539 schoenebeck 947 * general changes:
540     - replaced the old, confusing MIDI program change mechanism by a
541     flexible MIDI instrument mapper which allows to map arbitrary
542 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
543 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
544     loaded on the respective channel when such MIDI program change
545     messages arrive, beside that, each entry allows to define a life-time
546     strategy for the instrument, so the user can define whether the
547     instrument should i.e. be permanently loaded (to be able to switch
548     quickly among sounds) or i.e. loaded just on demand when the
549     respective program change arrives (to safe RAM space), as well as a
550     global volume factor for each entry, so the user can adjust the volume
551     dynamic of his mapped instrument collection without having to modify
552 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
553     MIDI instrument maps and assign each sampler channel individually
554     a certain map, so that i.e. separation of normal instruments and
555     drumkits is possible
556 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
557     MIDI instrument maps, MIDI instruments, FX sends, global volume.
558 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
559     due to a constant size RingBuffer FIFO which is now replaced by a
560     dynamic (unlimited) size std::list FIFO
561 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
562     output channels for being processed by external effect processors
563     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
564     controllers
565 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
566 iliev 1130 - Implemented new, improved notification system
567 schoenebeck 1149 - fixed compilation errors regarding OSX
568     (patch by Toshi Nagata)
569 iliev 1161 - implemented instruments database
570 iliev 1345 - added support for escape sequences to the instruments database
571 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
572     within the sampler's process (by using instrument editor plugins),
573     you'll notice the new "Registered instrument editors:" message on
574 schoenebeck 1407 startup, added a new LSCP command:
575     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
576 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
577     given sampler channel, the plugin path can be overridden at compile
578     time with ./configure --enable-plugin-dir=/some/dir
579 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
580     in the sampler's process to safely edit instruments while playing
581     without a crash (hopefully) by either suspending single regions
582     wherever possible or if unavoidable whole engine(s)
583 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
584     policy and priority on thread level, set a minimum stack size for
585     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
586     threads simply inherited properties of starting thread instead of
587     setting their own policy and priority
588 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
589     main process did not wait for the stack trace process to finish
590     its output
591 persson 1248 - fixed some minor memory leaks
592 schoenebeck 1259 - reenabled assembly features support, at the moment only for
593     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
594 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
595     register, to avoid relocations in the text segment at runtime)
596 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
597 schoenebeck 947
598     * MIDI driver:
599     - dispatch bank select (MSB and LSB) messages
600    
601 schoenebeck 1049 * audio driver:
602     - the ALSA audio output driver parameters now reflect the correct
603     parameter value ranges for the respective selected sound card
604     (patch by Till Wimmer, a bit fixed and extended)
605    
606 persson 951 * Gigasampler format engine:
607     - if a filter is used and EG2 finishes before EG1, let the voice
608     die when EG2 has finished (this fixes a problem with clicks and
609     voice starvation for some gigs)
610 persson 1038 - playback is no longer disabled during instrument loading
611     - all notes playing on a channel that changes its instrument keep
612     playing with the old instrument until they get a note off
613     command
614 persson 1039 - EG fix: a release value of zero could cause noises or crash
615 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
616 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
617     above max sustain level, which means that there is a decay phase
618     even if sustain is 100%
619 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
620     noises or crashes
621 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
622 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
623     supplied to the configure script (fixes #46)
624 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
625     instead of a fix value
626 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
627     127 (solo mode) only kill voices if the respective mode really
628     changed
629 persson 951
630 schoenebeck 1244 * LSCP server:
631     - fixed compile time error for old Bison versions
632     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
633 schoenebeck 1245 - parser now supports extended ASCII character set
634     (up to ASCII code 255, i.e. includes now umlauts and accents)
635     - filename arguments in LSCP commands now allow to use escape
636     sequences, that is directly literal as one of: \', \", \\, \n, \r,
637     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
638     code value like \xf2) (fixes bug #24)
639 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
640     least one of their text-based parameters (i.e. name, description):
641     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
642     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
643     "SET DB_INSTRUMENT_DIRECTORY NAME",
644     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
645     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
646     "FIND DB_INSTRUMENT_DIRECTORIES"
647 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
648     occured, the unexpected character and the actually expected, possible
649     character(s), the latter only if less than 5 possibilities)
650 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
651     settings
652 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
653     of strings were treated as being one string containing commas
654     (fixes #57)
655 schoenebeck 1244
656 iliev 959 * Bug fixes:
657     - fixed crash occurring on certain LSCP scripts (Bug 39)
658 persson 1038 - another thread safety fix for lscp "load engine" and "set
659     channel audio output device"
660 iliev 1283 - fixed a crash which occurs when reassigning the same engine
661     on a sampler channel with connected MIDI device
662 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
663     device connected to a sampler channel to number less then or equal
664     to the index of the port to which the sampler channel is connected.
665 iliev 1296 - The previous bindings were not been disconnected when altering
666     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
667     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
668 iliev 1297 - The active stream/voice count statistic was incorrect.
669 iliev 1298 - notification events were not been sent for some sampler
670     channel changes
671 iliev 1305 - added default min and max values to restrict the number of allowed
672     audio output channels and MIDI input ports
673 iliev 1306 - the connection to the PCM interface is now closed when destroying
674     an audio output device
675 schoenebeck 1332 - files with slash in their path or filename could not be loaded
676 iliev 959
677 schoenebeck 1221 * test cases:
678     - updated and fixed (haven't been touched in a while)
679    
680 schoenebeck 937 Version 0.4.0 (24 November 2006)
681 persson 696
682 schoenebeck 697 * packaging changes:
683 capela 868 - changed deprecated copyright attribute to license; added ldconfig
684     to post-(un)install steps; added devel package for liblinuxsampler;
685     to linuxsampler.spec (RPM)
686 schoenebeck 697 - install necessary development header files for allowing 3rd party
687     applications to link against liblinuxsampler
688     - liblinuxsampler's API documentation can be generated with 'make docs'
689     (Doxygen required)
690 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
691     implementation (currently either an integer math solution or a
692     di-harmonic approximation), automatic detection can be overriden
693     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
694     configure script argument though (mandatory for cross-compilation)
695 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
696     provided some on his own (as CXXFLAGS)
697 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
698     messages
699 schoenebeck 852 - added compile time options to allow disabling the various audio and
700     MIDI drivers
701 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
702     (patch by Ebrahim Mayat)
703 schoenebeck 697
704 persson 696 * Gigasampler format engine:
705 schoenebeck 738 - extensive synthesis optimization
706     (reimplementation of EGs and LFO(s), removed synthesis parameter
707     prerendering and the synthesis parameter matrix in general, splitting
708     each audio fragment into subfragments now where each subfragment uses
709 persson 830 constant pitch and filter coefficients. The volume coefficient is
710     linearly interpolated inside a subfragment, unless
711     --disable-interpolate-volume is set.)
712 persson 696 - fine tuning of the EG modulation parameters
713 persson 729 - improved filter cutoff calculation by adding support for the
714     following gig parameters: Cutoff freq (used when no cutoff
715     controller is defined), Control invert, Minimum cutoff, Velocity
716 persson 791 curve and Velocity range. The keyboard tracking now scales
717     cutoff frequency instead of resonance.
718 persson 877 - added support for gig parameter Resonance.
719 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
720 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
721     which can be overridden with --enable-global-attenuation
722 persson 783 - EG fixes: made the length of "attack hold" stage more
723     accurate. Release stage can now start before attack stage
724 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
725     time now has a minimal value to prevent clicks.
726 persson 799 - fixed pitch changes larger than one octave
727 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
728     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
729     all modes can be altered via standard GM messages, that is CC5 for
730     altering portamento time, CC65 for enabling / disabling portamento
731     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
732 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
733     parameter) and crossfade
734 persson 831 - added support for the "attenuation controller threshold" gig
735     parameter
736 persson 832 - added smoothing of volume changes caused by control change
737     messages
738 persson 865 - sample loop parameters are now taken from the DimensionRegion
739     instead of the wave chunk
740     - fixed keyswitching for v3 gigs with a number of keyswitch splits
741     not equal to a power of two
742 persson 877 - reimplementation of the filter algorithm. The new filter is more
743     accurate and supports all gig filter types, including bandreject
744     and lowpass turbo.
745 persson 903 - real support for 24 bit samples - samples are not truncated to
746     16 bits anymore
747     - support for aftertouch (channel pressure, not polyphonic
748     aftertouch)
749 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
750     amplifying from 0)
751 persson 696
752 schoenebeck 711 * LSCP server:
753     - fixed application exit on broken pipe error (fixes bug #20)
754 iliev 793 - fixed the notification messages delay due to lack of
755     network activity (fixes bug #26)
756 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
757     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
758 schoenebeck 711
759 schoenebeck 838 * audio driver:
760     - added aRts audio output driver (by no means RT safe)
761    
762 schoenebeck 775 * MIDI driver:
763     - fixed legacy sysex code which caused dispatching of MIDI SysEx
764     messages several times instead of once
765 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
766     for events (i.e. for offline rendering based MIDI drivers)
767 persson 922 - added checks for bad MIDI data
768 schoenebeck 775
769 schoenebeck 900 * linuxsampler application:
770     - show available sampler engine types on startup
771    
772 schoenebeck 705 * general changes:
773     - support for muting sampler channels and solo mode of the same, two new
774     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
775     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
776     introduced for this, the behavior is the same like on a mixer console
777 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
778     --enable-process-muted-channels which can be used to enable the
779     processing of muted channels.
780 iliev 777 - support for sostenuto pedal
781 iliev 779 - support for monitoring the total number of active voices
782 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
783     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
784 persson 835 - fixed some memory management errors
785 persson 841 - fixed some concurrency problems that could lead to crashes when
786     LSCP commands were executed
787 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
788     sampler channel (fixes bug #36)
789 schoenebeck 705
790 schoenebeck 692 Version 0.3.3 (15 July 2005)
791 schoenebeck 686
792     * packaging changes:
793     - fixed compilation with gcc 4.0
794    
795 schoenebeck 687 * Gigasampler format engine:
796     - LFO preprocessing was performed even though the respective LFO was
797     disabled by the instrument patch (minor efficiency fix)
798 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
799     for volume ramp downs in the same fragment (needed for current voice
800     stealing implementation) then simply inform the user with a warning
801     about possible click sounds and reduce the volume ramp down
802     appropriately instead of cancelling the audio device connection
803 schoenebeck 687
804 schoenebeck 677 Version 0.3.2 (24 June 2005)
805 schoenebeck 609
806     * packaging changes:
807     - updated autotools build files to compile on OS X
808     (conditional compilation of CoreMIDI and MidiShare drivers)
809 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
810     './configure --disable-asm' (definitely not recommended)
811 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
812     - require automake (>= 1.5) for 'make -f Makefile.cvs'
813     (due to 'dist-bzip2' automake option)
814 schoenebeck 649
815     * Gigasampler format engine:
816     - support for the gig parameters for "release velocity response" curves
817     - fine tuning of the EGADSR envelope
818     - volume of release triggered samples now depends on note-on velocity,
819     note length and gig parameter "release trigger decay" instead of
820     note-off velocity.
821 schoenebeck 663 - revised voice stealing
822     (fixes crash and endless loop caused by voice stealing)
823 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
824 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
825     instead of when the respective voice is actually launched
826     (fixes undefined behavior if stolen voices belonged to a key group -
827     this case was followed by a "killed voice survived" error message)
828 schoenebeck 669 - fixed minor issue with null/silence samples
829     (those stole voices even though they don't need a voice at all which
830     resulted in "voice stealing didn't work out" messages)
831 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
832     instrument or audio output device change
833 schoenebeck 654
834 schoenebeck 620 * LSCP server:
835 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
836 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
837 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
838 schoenebeck 609
839 schoenebeck 668 * linuxsampler application:
840     - added command line parameters --lscp-addr and --lscp-port to override
841     default IP address and port of LSCP server
842    
843 schoenebeck 579 Version 0.3.1 (24 May 2005)
844    
845     * initial release
