* Introduced Signal Units and Signal Unit Racks, which hopefully will meet
  the demands of the new engines for flexible signal processing.
* sf2: Initial implementation of vibrato LFO, fixes in modulation EG and
  and volume EG (work in progress)

1 schoenebeck 1993 Version CVS HEAD (?)
2    
3 capela 2174 * plugin changes:

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

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

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)

190 schoenebeck 1599
191 schoenebeck 1639 * packaging changes:

210 schoenebeck 1639
211 schoenebeck 1601 * general changes:
212     - bugfix: on some POSIX systems instrument editor plugins refused to

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

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

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

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

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

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