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

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

211 schoenebeck 1599
212 schoenebeck 1639 * packaging changes:
213     - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

231 schoenebeck 1639
232 schoenebeck 1601 * general changes:
233     - bugfix: on some POSIX systems instrument editor plugins refused to
234     load as we used a non-portable Linux specific struct field
235     (fixes bug #70, patch by Ronald Baljeu)
236 schoenebeck 1602 - fixed endless loop which occured when loading an instrument editor
237     plugin DLL on Windows systems failed
238 persson 1644 - fixed memory leaks that occurred when liblinuxsampler was unloaded

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

248     implementation, which is usually faster)
249 persson 1748 - fixes for audio drivers with varying buffer sizes
250 persson 1777 - experimental support for running LinuxSampler as a DSSI, LV2 and
251     VST plugin

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

267 persson 1887 - theoretical fix: made SynchronizedConfig follow C++0x memory
268     model more strictly
269 persson 1895 - fixes for using large audio device buffers
270 persson 1951 - Windows: add the installation directory to the DLL search path

277 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
278     opposed to the LSCP specs
279 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
280     reflected the wrong value
281 persson 1644 - fixed a memory management bug in ASIO driver
282 persson 1748 - Makefile fix: JACK_CFLAGS wasn't used

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

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

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

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

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

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