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

31     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
32     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
33     note (in this implementation of the sampler its simply hard routed to
34     the 1st effect send of the sampler channel, no matter what the actual
35     effect type is)
36     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
37     note (in this implementation of the sampler its simply hard routed to
38     the 2nd effect send of the sampler channel, no matter what the actual
39     effect type is)

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

253     - removed the nonsense audio channel constraint (which was hard coded to
254     max. 100 audio channels) for most audio drivers
255 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
256     opposed to the LSCP specs
257 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)

262 persson 1748 jack_client_new
263 iliev 1829 - added (experimental) CoreAudio driver
264 persson 1888 - applied old fixes to the ASIO driver that were included in the
265     previous binary release but accidentally never committed to CVS
266     (fixes #117)
267 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
268     win64)

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

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

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

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