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

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

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

215 schoenebeck 1599
216 schoenebeck 1639 * packaging changes:
217     - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

235 schoenebeck 1639
236 schoenebeck 1601 * general changes:
237     - bugfix: on some POSIX systems instrument editor plugins refused to

249 schoenebeck 1653 - be verbose on DLL load errors (on Linux)
250 schoenebeck 1681 - fixed di-harmonic triangle LFO implementation (this LFO implementation

262 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
263     be switched on by command line option "--stacktrace" (the automatic
264     stacktrace mechanism seems to be broken on most systems at the moment)
265 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
266     a pointer to the launched InstrumentEditor object
267 schoenebeck 1876 - added optional 3rd party user data parameter for following
268     liblinuxsampler C++ API methods: InstrumentEditor::Main(),
269     InstrumentEditor::Launch(),

281 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
282     opposed to the LSCP specs
283 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
284     reflected the wrong value

288 persson 1748 jack_client_new
289 iliev 1829 - added (experimental) CoreAudio driver
290 persson 1888 - applied old fixes to the ASIO driver that were included in the
291     previous binary release but accidentally never committed to CVS
292     (fixes #117)
293 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
294     win64)
295 persson 1895 - VST: added support for sample rate and buffer size changes
296     - VST: close editor (Fantasia) when the VST is removed

305     AudioChannel::CopyTo() methods using GCC vector exensions
306     (if available)
307 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
308     exception when getting parameters from a disconnected device
309 schoenebeck 1599
310 persson 1651 * MIDI driver:
311     - added JACK MIDI driver
312 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously

314     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
315 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
316 persson 1887 CoreMidi or AU
317 persson 1889 - fixed mingw-w64 compilation error in MME driver

329 persson 1908 - work-around for missing fnmatch function on Windows to make
330     instrument database compilable
331 schoenebeck 1930 - added instrument database support on Windows
332     works with both standalone mode and VST plugin.
333     the instruments DB file is located in
334     %USERPROFILE%\.linuxsampler\instruments.db which allows different
335     databases for each windows user
336     if no DB is present it automatically creates the .linuxsampler subdir
337     and then creates an empty DB
338 persson 1943 - fixed recursive import, which was broken on Windows
339 iliev 1603
340 persson 1644 * Gigasampler format engine:
341     - fixed a memory leak that could happen when a channel was deleted
342     while notes were playing
343 persson 1646 - made it possible to load an instrument even if the audio thread
344     isn't running
345 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
346     enough for piano gigs with pedal noise samples
347 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
348     respective FX send MIDI controller was used
349 schoenebeck 1724 - added support for GM global device volume SysEx message
350 schoenebeck 1762 (can be selected at compile time to either apply globally to the
351     whole sampler [default] or only to the sampler channels that are
352     connected to the respective MIDI input port the SysEx message arrived
353     on)
354 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
355     sometimes wrongly killed in the same buffer, causing no sound to
356     be played
357 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
358     which is usally used to switch a part between chromatic sounds and
359     drumkit sounds (as opposed to their common default setting of MIDI
360     part 10 being a drumkit part and all other ones chromatic parts), in
361     LS however one can switch between the first 16 MIDI instrument maps
362     defined for the sampler
363 persson 1764 - made it possible to create multiple sample channels even if the
364     audio thread isn't running
365 persson 1844 - fixed crash when removing channel with active voices (#116)
366 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
367     un-cache the respective sample if it's really not used by any
368     sampler engine anymore
369     - re-cache samples in case they were changed by an instrument editor,
370     e.g. when a sample was added while playing (#82)
371 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
372     same time stamp as the voice's note-on event and occured both in the
373     same audio fragment cycle (fixes bug #112)
374 persson 1858 - added support for the "fine tune" and "pitch bend range"
375     instrument-level gig parameters
376     - fixed minor artifacts in pitch bend handling

382 persson 1923 - fixed crash happening when a pitch bend event arrived at the
383     same time a new instrument was loading
384 persson 1644
385 schoenebeck 1687 * LSCP server:
386     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
387     react on MIDI data arriving on certain sampler channels (so far only
388     Note-On and Note-Off events are sent via this LSCP event)
389 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
390     react on MIDI data arriving on certain MIDI input devices (so far only
391     Note-On and Note-Off events are sent via this LSCP event)
392 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
393     SET DB_INSTRUMENT FILE_PATH

397     KEY_BINDINGS and KEYSWITCH_BINDINGS
398 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
399     was incorrect
400 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
401 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
402     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
403     be triggered respectively
404     - added new LSCP command "SET STREAMS" to globally alter the maximum
405     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
406     which will be triggered respectively
407 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
408     a gigedit file dialog is opened)
409 iliev 1848 - close all connections when LSCPServer is deleted
410 iliev 1882 - hard close of all sockets on exit
411 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
412     driver
413 schoenebeck 1687
414 iliev 1761 * Bug fixes:
415     - fixed a crash which occurs when removing a sampler channel waiting
416     to start instrument loading after another channel
417 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
418     instrument loading in progress (bug #113)
419 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
420     instrument with PERSISTENT load mode
421 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
422     - fixed memory leaks when issuing the following LSCP commands:

424     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
425     GET MIDI_INPUT_DRIVER INFO
426     GET MIDI_INPUT_DRIVER_PARAMETER INFO
427     - fixed possible compilation error when sqlite is not present
428 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
429 iliev 1847 - fixed crash when changing the audio output device of a sampler
430     channel with loaded instrument and start playing notes
431 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
432 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
433     PowerPC, which probably could cause crashes on that platform
434 persson 1889 - fixed a memory management error which could cause a crash when a
435     plugin was unloaded
436 persson 1896 - bugfix: two private structs had the same name, which could cause
437     problems if the linker chose the wrong constructor
438 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
439     Windows

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

775 schoenebeck 677 Version 0.3.2 (24 June 2005)
776 schoenebeck 609
777     * packaging changes:
778     - updated autotools build files to compile on OS X
779     (conditional compilation of CoreMIDI and MidiShare drivers)
780 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
781     './configure --disable-asm' (definitely not recommended)
782 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
783     - require automake (>= 1.5) for 'make -f Makefile.cvs'
784     (due to 'dist-bzip2' automake option)
785 schoenebeck 649
786     * Gigasampler format engine:
787     - support for the gig parameters for "release velocity response" curves
788     - fine tuning of the EGADSR envelope
789     - volume of release triggered samples now depends on note-on velocity,
790     note length and gig parameter "release trigger decay" instead of
791     note-off velocity.
792 schoenebeck 663 - revised voice stealing
793     (fixes crash and endless loop caused by voice stealing)
794 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
795 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
796     instead of when the respective voice is actually launched
797     (fixes undefined behavior if stolen voices belonged to a key group -
798     this case was followed by a "killed voice survived" error message)
799 schoenebeck 669 - fixed minor issue with null/silence samples
800     (those stole voices even though they don't need a voice at all which
801     resulted in "voice stealing didn't work out" messages)
802 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
803     instrument or audio output device change
804 schoenebeck 654
805 schoenebeck 620 * LSCP server:
806 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
807 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
808 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
809 schoenebeck 609
810 schoenebeck 668 * linuxsampler application:
811     - added command line parameters --lscp-addr and --lscp-port to override
812     default IP address and port of LSCP server
813    
814 schoenebeck 579 Version 0.3.1 (24 May 2005)
815    
816     * initial release
