1 schoenebeck 1993 Version CVS HEAD (?)
2    
3 capela 2174 * plugin changes:
4     - LV2 Persist + Files support (patch by David Robillard)

7     - fixed building with newer MinGW-w64
8 persson 2183 - Mac OS X: support the new dir for Core Audio SDK
9     - Mac OS X: fixed building outside source directory
10     - made sure all source files for hostplugins are included when
11     doing "make dist"
12     - removed empty directories left from the cvs to svn migration
13 persson 2185 - fixed compilation with gcc 4.6.1
14 persson 2203 - another "make dist" fix, for the LV2 plugin
15 persson 2185 - made --enable-pthread-testcancel default on Mac OS X
16 persson 2197 - minor Makefile fix for building lscpparser when build and source
17     directories are separate

20 persson 2208 - Mac OS X: Makefile fix for the install-strip target
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

290 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
291     be switched on by command line option "--stacktrace" (the automatic
292     stacktrace mechanism seems to be broken on most systems at the moment)
293 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
294     a pointer to the launched InstrumentEditor object
295 schoenebeck 1876 - added optional 3rd party user data parameter for following
296     liblinuxsampler C++ API methods: InstrumentEditor::Main(),
297     InstrumentEditor::Launch(),

317 iliev 1829 - added (experimental) CoreAudio driver
318 persson 1888 - applied old fixes to the ASIO driver that were included in the
319     previous binary release but accidentally never committed to CVS
320     (fixes #117)
321 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
322     win64)
323 persson 1895 - VST: added support for sample rate and buffer size changes
324     - VST: close editor (Fantasia) when the VST is removed

336     exception when getting parameters from a disconnected device
337 schoenebeck 1599
338 persson 1651 * MIDI driver:
339     - added JACK MIDI driver
340 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously

358     instrument database compilable
359 schoenebeck 1930 - added instrument database support on Windows
360     works with both standalone mode and VST plugin.
361     the instruments DB file is located in
362     %USERPROFILE%\.linuxsampler\instruments.db which allows different
363     databases for each windows user
364     if no DB is present it automatically creates the .linuxsampler subdir
365     and then creates an empty DB
366 persson 1943 - fixed recursive import, which was broken on Windows
367 iliev 1603
368 persson 1644 * Gigasampler format engine:
369     - fixed a memory leak that could happen when a channel was deleted
370     while notes were playing
371 persson 1646 - made it possible to load an instrument even if the audio thread
372     isn't running
373 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
374     enough for piano gigs with pedal noise samples
375 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
376     respective FX send MIDI controller was used
377 schoenebeck 1724 - added support for GM global device volume SysEx message
378 schoenebeck 1762 (can be selected at compile time to either apply globally to the
379     whole sampler [default] or only to the sampler channels that are
380     connected to the respective MIDI input port the SysEx message arrived
381     on)
382 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
383     sometimes wrongly killed in the same buffer, causing no sound to
384     be played
385 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
386     which is usally used to switch a part between chromatic sounds and
387     drumkit sounds (as opposed to their common default setting of MIDI
388     part 10 being a drumkit part and all other ones chromatic parts), in
389     LS however one can switch between the first 16 MIDI instrument maps
390     defined for the sampler
391 persson 1764 - made it possible to create multiple sample channels even if the
392     audio thread isn't running
393 persson 1844 - fixed crash when removing channel with active voices (#116)
394 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
395     un-cache the respective sample if it's really not used by any
396     sampler engine anymore
397     - re-cache samples in case they were changed by an instrument editor,
398     e.g. when a sample was added while playing (#82)
399 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
400     same time stamp as the voice's note-on event and occured both in the
401     same audio fragment cycle (fixes bug #112)
402 persson 1858 - added support for the "fine tune" and "pitch bend range"
403     instrument-level gig parameters
404     - fixed minor artifacts in pitch bend handling
405 schoenebeck 1860 - added support for GS Reset SysEx message
406 persson 1862 - allow gig files to use unlimited downward pitch shifting
407     - added a limit check for upward pitch shifting
408 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
409     note was silent
410 persson 1923 - fixed crash happening when a pitch bend event arrived at the
411     same time a new instrument was loading
412 persson 1644
413 schoenebeck 1687 * LSCP server:
414     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
415     react on MIDI data arriving on certain sampler channels (so far only
416     Note-On and Note-Off events are sent via this LSCP event)
417 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
418     react on MIDI data arriving on certain MIDI input devices (so far only
419     Note-On and Note-Off events are sent via this LSCP event)
420 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
421     SET DB_INSTRUMENT FILE_PATH
422 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
423     frontends to send MIDI messages to specific sampler channel
424     - added two additional fields to GET FILE INSTRUMENT INFO command -
425     KEY_BINDINGS and KEYSWITCH_BINDINGS
426 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
427     was incorrect
428 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
429 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
430     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
431     be triggered respectively
432     - added new LSCP command "SET STREAMS" to globally alter the maximum
433     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
434     which will be triggered respectively
435 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
436     a gigedit file dialog is opened)
437 iliev 1848 - close all connections when LSCPServer is deleted
438 iliev 1882 - hard close of all sockets on exit
439 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
440     driver
441 schoenebeck 1687
442 iliev 1761 * Bug fixes:
443     - fixed a crash which occurs when removing a sampler channel waiting
444     to start instrument loading after another channel
445 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
446     instrument loading in progress (bug #113)
447 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
448     instrument with PERSISTENT load mode
449 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
450     - fixed memory leaks when issuing the following LSCP commands:
451     GET AUDIO_OUTPUT_DRIVER INFO
452     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
453     GET MIDI_INPUT_DRIVER INFO
454     GET MIDI_INPUT_DRIVER_PARAMETER INFO
455     - fixed possible compilation error when sqlite is not present
456 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
457 iliev 1847 - fixed crash when changing the audio output device of a sampler
458     channel with loaded instrument and start playing notes
459 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
460 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
461     PowerPC, which probably could cause crashes on that platform
462 persson 1889 - fixed a memory management error which could cause a crash when a
463     plugin was unloaded
464 persson 1896 - bugfix: two private structs had the same name, which could cause
465     problems if the linker chose the wrong constructor
466 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
467     Windows
468 iliev 1761
469    
470 schoenebeck 1560 Version 0.5.1 (6 December 2007)
471 schoenebeck 1454
472     * packaging changes:
473     - added autoconf checks for pthread library
474     - added autoconf check for pthread bug found on certain NPTL-enabled
475     glibc versions (see Gentoo bug report #194076)
476 senoner 1502 - added autoconf checks for MS Windows
477 schoenebeck 1454
478 persson 1455 * general changes:
479     - bugfix: the thread used by an editor plugin didn't die when the
480     editor closed
481 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
482     out all the space. operator--() did not apply size_mask after
483     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
484     order to avoid problems with the _NonVolatileReader functions.
485     - bugfix: Stream.h: added a missing divide by BytesPerSample in
486     GetWriteSpace(). Since this function is currently only used in
487     the stream's qsort() compare function, it didn't trigger any
488     bugs.
489     - Resampler.h, Synthesizer.h: cubic interpolation now works in
490     24bit mode too. Faster method to read 24bit words on little
491     endian machines (x86): replaced 3 byte reads + shifts with a 1
492     unaligned 32bit read and shift
493     - experimental support for MS Windows (MIDI input via MME, AUDIO
494     output via ASIO)
495     - made handling of SIGINT signal (Ctrl-C) a bit more robust
496 iliev 1541 - support for monitoring the total number of active disk streams
497     (new LSCP commands: GET TOTAL_STREAM_COUNT,
498     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
499 persson 1455
500 senoner 1500 * AUDIO driver:
501 persson 1534 - added Windows ASIO low latency audio driver
502 senoner 1500
503 senoner 1485 * MIDI driver:
504 schoenebeck 1495 - added MME Windows MIDI driver
505 senoner 1485
506 schoenebeck 1471 * LSCP server:
507     - added support for Windows style path / filenames, however with
508     forward slash path separators instead of backslash
509     (i.e. "C:/foo/bar.gig")
510 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
511     apostrophes as well
512 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
513     "LIST FILE INSTRUMENTS <file>" and
514     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
515     about an arbitrary instrument file on the system where the sampler is
516     running on
517 schoenebeck 1471
518 schoenebeck 1424 Version 0.5.0 (15 October 2007)
519 schoenebeck 947
520 schoenebeck 1065 * packaging changes:
521 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
522     API header files anymore
523 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
524     the Doxygen API documentation (explicitly listed in Doxyfile.in)
525 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
526     capable to execute our autoconf environment, thus no need anymore
527     to maintain the compile time configuration file (osx/version.h) for
528     OSX manually (patch by Toshi Nagata)
529 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
530     parameters
531 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
532     C++ API header files, all implementation internal global definitions
533     are now in global_private.h
534     - atomic.h is not exposed to the C++ API anymore
535     - no need to include config.h anymore for using LS's API header files
536     - fixed warnings in API doc generation
537 schoenebeck 1065
538 schoenebeck 947 * general changes:
539     - replaced the old, confusing MIDI program change mechanism by a
540     flexible MIDI instrument mapper which allows to map arbitrary
541 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
542 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
543     loaded on the respective channel when such MIDI program change
544     messages arrive, beside that, each entry allows to define a life-time
545     strategy for the instrument, so the user can define whether the
546     instrument should i.e. be permanently loaded (to be able to switch
547     quickly among sounds) or i.e. loaded just on demand when the
548     respective program change arrives (to safe RAM space), as well as a
549     global volume factor for each entry, so the user can adjust the volume
550     dynamic of his mapped instrument collection without having to modify
551 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
552     MIDI instrument maps and assign each sampler channel individually
553     a certain map, so that i.e. separation of normal instruments and
554     drumkits is possible
555 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
556     MIDI instrument maps, MIDI instruments, FX sends, global volume.
557 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
558     due to a constant size RingBuffer FIFO which is now replaced by a
559     dynamic (unlimited) size std::list FIFO
560 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
561     output channels for being processed by external effect processors
562     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
563     controllers
564 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
565 iliev 1130 - Implemented new, improved notification system
566 schoenebeck 1149 - fixed compilation errors regarding OSX
567     (patch by Toshi Nagata)
568 iliev 1161 - implemented instruments database
569 iliev 1345 - added support for escape sequences to the instruments database
570 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
571     within the sampler's process (by using instrument editor plugins),
572     you'll notice the new "Registered instrument editors:" message on
573 schoenebeck 1407 startup, added a new LSCP command:
574     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
575 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
576     given sampler channel, the plugin path can be overridden at compile
577     time with ./configure --enable-plugin-dir=/some/dir
578 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
579     in the sampler's process to safely edit instruments while playing
580     without a crash (hopefully) by either suspending single regions
581     wherever possible or if unavoidable whole engine(s)
582 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
583     policy and priority on thread level, set a minimum stack size for
584     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
585     threads simply inherited properties of starting thread instead of
586     setting their own policy and priority
587 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
588     main process did not wait for the stack trace process to finish
589     its output
590 persson 1248 - fixed some minor memory leaks
591 schoenebeck 1259 - reenabled assembly features support, at the moment only for
592     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
593 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
594     register, to avoid relocations in the text segment at runtime)
595 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
596 schoenebeck 947
597     * MIDI driver:
598     - dispatch bank select (MSB and LSB) messages
599    
600 schoenebeck 1049 * audio driver:
601     - the ALSA audio output driver parameters now reflect the correct
602     parameter value ranges for the respective selected sound card
603     (patch by Till Wimmer, a bit fixed and extended)
604    
605 persson 951 * Gigasampler format engine:
606     - if a filter is used and EG2 finishes before EG1, let the voice
607     die when EG2 has finished (this fixes a problem with clicks and
608     voice starvation for some gigs)
609 persson 1038 - playback is no longer disabled during instrument loading
610     - all notes playing on a channel that changes its instrument keep
611     playing with the old instrument until they get a note off
612     command
613 persson 1039 - EG fix: a release value of zero could cause noises or crash
614 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
615 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
616     above max sustain level, which means that there is a decay phase
617     even if sustain is 100%
618 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
619     noises or crashes
620 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
621 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
622     supplied to the configure script (fixes #46)
623 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
624     instead of a fix value
625 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
626     127 (solo mode) only kill voices if the respective mode really
627     changed
628 persson 951
629 schoenebeck 1244 * LSCP server:
630     - fixed compile time error for old Bison versions
631     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
632 schoenebeck 1245 - parser now supports extended ASCII character set
633     (up to ASCII code 255, i.e. includes now umlauts and accents)
634     - filename arguments in LSCP commands now allow to use escape
635     sequences, that is directly literal as one of: \', \", \\, \n, \r,
636     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
637     code value like \xf2) (fixes bug #24)
638 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
639     least one of their text-based parameters (i.e. name, description):
640     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
641     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
642     "SET DB_INSTRUMENT_DIRECTORY NAME",
643     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
644     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
645     "FIND DB_INSTRUMENT_DIRECTORIES"
646 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
647     occured, the unexpected character and the actually expected, possible
648     character(s), the latter only if less than 5 possibilities)
649 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
650     settings
651 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
652     of strings were treated as being one string containing commas
653     (fixes #57)
654 schoenebeck 1244
655 iliev 959 * Bug fixes:
656     - fixed crash occurring on certain LSCP scripts (Bug 39)
657 persson 1038 - another thread safety fix for lscp "load engine" and "set
658     channel audio output device"
659 iliev 1283 - fixed a crash which occurs when reassigning the same engine
660     on a sampler channel with connected MIDI device
661 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
662     device connected to a sampler channel to number less then or equal
663     to the index of the port to which the sampler channel is connected.
664 iliev 1296 - The previous bindings were not been disconnected when altering
665     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
666     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
667 iliev 1297 - The active stream/voice count statistic was incorrect.
668 iliev 1298 - notification events were not been sent for some sampler
669     channel changes
670 iliev 1305 - added default min and max values to restrict the number of allowed
671     audio output channels and MIDI input ports
672 iliev 1306 - the connection to the PCM interface is now closed when destroying
673     an audio output device
674 schoenebeck 1332 - files with slash in their path or filename could not be loaded
675 iliev 959
676 schoenebeck 1221 * test cases:
677     - updated and fixed (haven't been touched in a while)
678    
679 schoenebeck 937 Version 0.4.0 (24 November 2006)
680 persson 696
681 schoenebeck 697 * packaging changes:
682 capela 868 - changed deprecated copyright attribute to license; added ldconfig
683     to post-(un)install steps; added devel package for liblinuxsampler;
684     to linuxsampler.spec (RPM)
685 schoenebeck 697 - install necessary development header files for allowing 3rd party
686     applications to link against liblinuxsampler
687     - liblinuxsampler's API documentation can be generated with 'make docs'
688     (Doxygen required)
689 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
690     implementation (currently either an integer math solution or a
691     di-harmonic approximation), automatic detection can be overriden
692     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
693     configure script argument though (mandatory for cross-compilation)
694 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
695     provided some on his own (as CXXFLAGS)
696 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
697     messages
698 schoenebeck 852 - added compile time options to allow disabling the various audio and
699     MIDI drivers
700 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
701     (patch by Ebrahim Mayat)
702 schoenebeck 697
703 persson 696 * Gigasampler format engine:
704 schoenebeck 738 - extensive synthesis optimization
705     (reimplementation of EGs and LFO(s), removed synthesis parameter
706     prerendering and the synthesis parameter matrix in general, splitting
707     each audio fragment into subfragments now where each subfragment uses
708 persson 830 constant pitch and filter coefficients. The volume coefficient is
709     linearly interpolated inside a subfragment, unless
710     --disable-interpolate-volume is set.)
711 persson 696 - fine tuning of the EG modulation parameters
712 persson 729 - improved filter cutoff calculation by adding support for the
713     following gig parameters: Cutoff freq (used when no cutoff
714     controller is defined), Control invert, Minimum cutoff, Velocity
715 persson 791 curve and Velocity range. The keyboard tracking now scales
716     cutoff frequency instead of resonance.
717 persson 877 - added support for gig parameter Resonance.
718 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
719 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
720     which can be overridden with --enable-global-attenuation
721 persson 783 - EG fixes: made the length of "attack hold" stage more
722     accurate. Release stage can now start before attack stage
723 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
724     time now has a minimal value to prevent clicks.
725 persson 799 - fixed pitch changes larger than one octave
726 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
727     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
728     all modes can be altered via standard GM messages, that is CC5 for
729     altering portamento time, CC65 for enabling / disabling portamento
730     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
731 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
732     parameter) and crossfade
733 persson 831 - added support for the "attenuation controller threshold" gig
734     parameter
735 persson 832 - added smoothing of volume changes caused by control change
736     messages
737 persson 865 - sample loop parameters are now taken from the DimensionRegion
738     instead of the wave chunk
739     - fixed keyswitching for v3 gigs with a number of keyswitch splits
740     not equal to a power of two
741 persson 877 - reimplementation of the filter algorithm. The new filter is more
742     accurate and supports all gig filter types, including bandreject
743     and lowpass turbo.
744 persson 903 - real support for 24 bit samples - samples are not truncated to
745     16 bits anymore
746     - support for aftertouch (channel pressure, not polyphonic
747     aftertouch)
748 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
749     amplifying from 0)
750 persson 696
751 schoenebeck 711 * LSCP server:
752     - fixed application exit on broken pipe error (fixes bug #20)
753 iliev 793 - fixed the notification messages delay due to lack of
754     network activity (fixes bug #26)
755 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
756     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
757 schoenebeck 711
758 schoenebeck 838 * audio driver:
759     - added aRts audio output driver (by no means RT safe)
760    
761 schoenebeck 775 * MIDI driver:
762     - fixed legacy sysex code which caused dispatching of MIDI SysEx
763     messages several times instead of once
764 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
765     for events (i.e. for offline rendering based MIDI drivers)
766 persson 922 - added checks for bad MIDI data
767 schoenebeck 775
768 schoenebeck 900 * linuxsampler application:
769     - show available sampler engine types on startup
770    
771 schoenebeck 705 * general changes:
772     - support for muting sampler channels and solo mode of the same, two new
773     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
774     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
775     introduced for this, the behavior is the same like on a mixer console
776 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
777     --enable-process-muted-channels which can be used to enable the
778     processing of muted channels.
779 iliev 777 - support for sostenuto pedal
780 iliev 779 - support for monitoring the total number of active voices
781 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
782     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
783 persson 835 - fixed some memory management errors
784 persson 841 - fixed some concurrency problems that could lead to crashes when
785     LSCP commands were executed
786 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
787     sampler channel (fixes bug #36)
788 schoenebeck 705
789 schoenebeck 692 Version 0.3.3 (15 July 2005)
790 schoenebeck 686
791     * packaging changes:
792     - fixed compilation with gcc 4.0
793    
794 schoenebeck 687 * Gigasampler format engine:
795     - LFO preprocessing was performed even though the respective LFO was
796     disabled by the instrument patch (minor efficiency fix)
797 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
798     for volume ramp downs in the same fragment (needed for current voice
799     stealing implementation) then simply inform the user with a warning
800     about possible click sounds and reduce the volume ramp down
801     appropriately instead of cancelling the audio device connection
802 schoenebeck 687
803 schoenebeck 677 Version 0.3.2 (24 June 2005)
804 schoenebeck 609
805     * packaging changes:
806     - updated autotools build files to compile on OS X
807     (conditional compilation of CoreMIDI and MidiShare drivers)
808 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
809     './configure --disable-asm' (definitely not recommended)
810 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
811     - require automake (>= 1.5) for 'make -f Makefile.cvs'
812     (due to 'dist-bzip2' automake option)
813 schoenebeck 649
814     * Gigasampler format engine:
815     - support for the gig parameters for "release velocity response" curves
816     - fine tuning of the EGADSR envelope
817     - volume of release triggered samples now depends on note-on velocity,
818     note length and gig parameter "release trigger decay" instead of
819     note-off velocity.
820 schoenebeck 663 - revised voice stealing
821     (fixes crash and endless loop caused by voice stealing)
822 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
823 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
824     instead of when the respective voice is actually launched
825     (fixes undefined behavior if stolen voices belonged to a key group -
826     this case was followed by a "killed voice survived" error message)
827 schoenebeck 669 - fixed minor issue with null/silence samples
828     (those stole voices even though they don't need a voice at all which
829     resulted in "voice stealing didn't work out" messages)
830 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
831     instrument or audio output device change
832 schoenebeck 654
833 schoenebeck 620 * LSCP server:
834 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
835 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
836 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
837 schoenebeck 609
838 schoenebeck 668 * linuxsampler application:
839     - added command line parameters --lscp-addr and --lscp-port to override
840     default IP address and port of LSCP server
841    
842 schoenebeck 579 Version 0.3.1 (24 May 2005)
843    
844     * initial release
