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

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

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

193 schoenebeck 1599
194 schoenebeck 1639 * packaging changes:

213 schoenebeck 1639
214 schoenebeck 1601 * general changes:
215     - bugfix: on some POSIX systems instrument editor plugins refused to

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

266 persson 1748 jack_client_new
267 iliev 1829 - added (experimental) CoreAudio driver
268 persson 1888 - applied old fixes to the ASIO driver that were included in the
269     previous binary release but accidentally never committed to CVS
270     (fixes #117)
271 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
272     win64)
273 persson 1895 - VST: added support for sample rate and buffer size changes
274     - VST: close editor (Fantasia) when the VST is removed

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

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

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