* sfz/sf2 engine: fixed crash when using small audio fragment size

1 schoenebeck 1993 Version CVS HEAD (?)
2    
3 capela 2174 * plugin changes:
4 schoenebeck 2304 - LV2 "state" extension support (patch by David Robillard)
5 capela 2174
6 persson 2086 * packaging 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
18 persson 2203 - Mac OS X: made it possible to specify plugin installation dir to
19     configure
20 persson 2208 - Mac OS X: Makefile fix for the install-strip target
21 persson 2086
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
28     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
29     where the sampler shall look for instrument editor plugins
30     (patch by Luis Garrido, slightly modified).

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)

344 schoenebeck 1928 directory of liblinuxsampler dll (look in the same directory and one
345     directory above)
346 persson 1899 - configure script fix: removed unconditional use of SSE
347 persson 1923 - fixed building with sqlite installed in a non-standard directory

350 schoenebeck 1639
351 schoenebeck 1601 * general changes:
352     - bugfix: on some POSIX systems instrument editor plugins refused to
353     load as we used a non-portable Linux specific struct field
354     (fixes bug #70, patch by Ronald Baljeu)
355 schoenebeck 1602 - fixed endless loop which occured when loading an instrument editor
356     plugin DLL on Windows systems failed
357 persson 1644 - fixed memory leaks that occurred when liblinuxsampler was unloaded
358     - optimized the SynchronizedConfig class so it doesn't wait
359     unnecessarily long after an update
360 schoenebeck 1653 - added support for notifying instrument editors on note-on / note-off
361     events (e.g. to highlight the pressed keys on the virtual keyboard
362     of gigedit)
363 schoenebeck 1659 - added support for triggering notes by instrument editors (see above)
364 schoenebeck 1653 - be verbose on DLL load errors (on Linux)
365 schoenebeck 1681 - fixed di-harmonic triangle LFO implementation (this LFO implementation
366     is only used by very few systems, most pick the int math
367     implementation, which is usually faster)
368 persson 1748 - fixes for audio drivers with varying buffer sizes
369 persson 1777 - experimental support for running LinuxSampler as a DSSI, LV2 and
370     VST plugin

374     multi-core and multi-cpu systems
375 schoenebeck 1800 - maximum voices and disk streams can now be altered at runtime
376 persson 1825 - fixed CPU feature detection on x86_64 (maybe fixes #108)
377 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
378     be switched on by command line option "--stacktrace" (the automatic
379     stacktrace mechanism seems to be broken on most systems at the moment)
380 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
381     a pointer to the launched InstrumentEditor object
382 schoenebeck 1876 - added optional 3rd party user data parameter for following
383     liblinuxsampler C++ API methods: InstrumentEditor::Main(),
384     InstrumentEditor::Launch(),
385     InstrumentManager::LaunchInstrumentEditor()
386 persson 1887 - theoretical fix: made SynchronizedConfig follow C++0x memory
387     model more strictly
388 persson 1895 - fixes for using large audio device buffers
389 persson 1951 - Windows: add the installation directory to the DLL search path
390     when loading an editor plugin (solves problems with VST and
391     gigedit on systems with other GTK versions installed)
392 schoenebeck 1601
393 schoenebeck 1599 * audio driver:
394     - removed the nonsense audio channel constraint (which was hard coded to
395     max. 100 audio channels) for most audio drivers
396 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
397     opposed to the LSCP specs
398 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
399     reflected the wrong value
400 persson 1644 - fixed a memory management bug in ASIO driver
401 persson 1748 - Makefile fix: JACK_CFLAGS wasn't used
402 persson 1777 - JACK: use jack_client_open instead of the deprecated
403 persson 1748 jack_client_new
404 iliev 1829 - added (experimental) CoreAudio driver
405 persson 1888 - applied old fixes to the ASIO driver that were included in the
406     previous binary release but accidentally never committed to CVS
407     (fixes #117)
408 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
409     win64)
410 persson 1895 - VST: added support for sample rate and buffer size changes
411     - VST: close editor (Fantasia) when the VST is removed
412 persson 1908 - VST: avoid opening Fantasia more than once for each VST instance
413     - VST: export main function as "main" on Linux too (fix for
414     energyXT)

416     stereo
417 persson 1922 - added channel routing, fxsends and midi maps to the settings
418     stored in the plugin state
419 schoenebeck 1930 - performance optimization of AudioChannel::MixTo() and
420     AudioChannel::CopyTo() methods using GCC vector exensions
421     (if available)
422 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
423     exception when getting parameters from a disconnected device
424 schoenebeck 1599
425 persson 1651 * MIDI driver:
426     - added JACK MIDI driver
427 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
428     want to (mis)use it for some purpose ("fixed" in all current MIDI
429     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
430 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
431 persson 1887 CoreMidi or AU
432 persson 1889 - fixed mingw-w64 compilation error in MME driver
433 persson 1924 - made program change handling in MIDI thread real-time safe by
434     moving the logic to a non-RT thread
435 persson 1951 - fixed minor memory leak in ALSA driver
436 persson 1651
437 schoenebeck 1604 * instruments database:
438 iliev 1603 - avoid time consuming samples scanning when adding instruments
439     to the instruments database
440 iliev 1727 - added support for handling lost files in the instruments database
441 iliev 1781 - Implemented option for adding instruments in separate directories
442     in the instruments database
443     (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
444 persson 1908 - work-around for missing fnmatch function on Windows to make
445     instrument database compilable
446 schoenebeck 1930 - added instrument database support on Windows
447     works with both standalone mode and VST plugin.
448     the instruments DB file is located in
449     %USERPROFILE%\.linuxsampler\instruments.db which allows different
450     databases for each windows user
451     if no DB is present it automatically creates the .linuxsampler subdir
452     and then creates an empty DB
453 persson 1943 - fixed recursive import, which was broken on Windows
454 iliev 1603
455 persson 1644 * Gigasampler format engine:
456     - fixed a memory leak that could happen when a channel was deleted
457     while notes were playing
458 persson 1646 - made it possible to load an instrument even if the audio thread
459     isn't running
460 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
461     enough for piano gigs with pedal noise samples
462 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
463     respective FX send MIDI controller was used
464 schoenebeck 1724 - added support for GM global device volume SysEx message
465 schoenebeck 1762 (can be selected at compile time to either apply globally to the
466     whole sampler [default] or only to the sampler channels that are
467     connected to the respective MIDI input port the SysEx message arrived
468     on)
469 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
470     sometimes wrongly killed in the same buffer, causing no sound to
471     be played
472 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
473     which is usally used to switch a part between chromatic sounds and
474     drumkit sounds (as opposed to their common default setting of MIDI
475     part 10 being a drumkit part and all other ones chromatic parts), in
476     LS however one can switch between the first 16 MIDI instrument maps
477     defined for the sampler
478 persson 1764 - made it possible to create multiple sample channels even if the
479     audio thread isn't running
480 persson 1844 - fixed crash when removing channel with active voices (#116)
481 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
482     un-cache the respective sample if it's really not used by any
483     sampler engine anymore
484     - re-cache samples in case they were changed by an instrument editor,
485     e.g. when a sample was added while playing (#82)
486 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
487     same time stamp as the voice's note-on event and occured both in the
488     same audio fragment cycle (fixes bug #112)
489 persson 1858 - added support for the "fine tune" and "pitch bend range"
490     instrument-level gig parameters
491     - fixed minor artifacts in pitch bend handling
492 schoenebeck 1860 - added support for GS Reset SysEx message
493 persson 1862 - allow gig files to use unlimited downward pitch shifting
494     - added a limit check for upward pitch shifting
495 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
496     note was silent
497 persson 1923 - fixed crash happening when a pitch bend event arrived at the
498     same time a new instrument was loading
499 persson 1644
500 schoenebeck 1687 * LSCP server:
501     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
502     react on MIDI data arriving on certain sampler channels (so far only
503     Note-On and Note-Off events are sent via this LSCP event)
504 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
505     react on MIDI data arriving on certain MIDI input devices (so far only
506     Note-On and Note-Off events are sent via this LSCP event)
507 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
508     SET DB_INSTRUMENT FILE_PATH
509 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
510     frontends to send MIDI messages to specific sampler channel
511     - added two additional fields to GET FILE INSTRUMENT INFO command -
512     KEY_BINDINGS and KEYSWITCH_BINDINGS
513 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
514     was incorrect
515 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
516 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
517     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
518     be triggered respectively
519     - added new LSCP command "SET STREAMS" to globally alter the maximum
520     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
521     which will be triggered respectively
522 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
523     a gigedit file dialog is opened)
524 iliev 1848 - close all connections when LSCPServer is deleted
525 iliev 1882 - hard close of all sockets on exit
526 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
527     driver
528 schoenebeck 1687
529 iliev 1761 * Bug fixes:
530     - fixed a crash which occurs when removing a sampler channel waiting
531     to start instrument loading after another channel
532 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
533     instrument loading in progress (bug #113)
534 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
535     instrument with PERSISTENT load mode
536 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
537     - fixed memory leaks when issuing the following LSCP commands:
538     GET AUDIO_OUTPUT_DRIVER INFO
539     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
540     GET MIDI_INPUT_DRIVER INFO
541     GET MIDI_INPUT_DRIVER_PARAMETER INFO
542     - fixed possible compilation error when sqlite is not present
543 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
544 iliev 1847 - fixed crash when changing the audio output device of a sampler
545     channel with loaded instrument and start playing notes
546 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
547 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
548     PowerPC, which probably could cause crashes on that platform
549 persson 1889 - fixed a memory management error which could cause a crash when a
550     plugin was unloaded
551 persson 1896 - bugfix: two private structs had the same name, which could cause
552     problems if the linker chose the wrong constructor
553 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
554     Windows
555 iliev 1761
556    
557 schoenebeck 1560 Version 0.5.1 (6 December 2007)
558 schoenebeck 1454
559     * packaging changes:
560     - added autoconf checks for pthread library
561     - added autoconf check for pthread bug found on certain NPTL-enabled
562     glibc versions (see Gentoo bug report #194076)
563 senoner 1502 - added autoconf checks for MS Windows
564 schoenebeck 1454
565 persson 1455 * general changes:
566     - bugfix: the thread used by an editor plugin didn't die when the
567     editor closed
568 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
569     out all the space. operator--() did not apply size_mask after
570     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
571     order to avoid problems with the _NonVolatileReader functions.
572     - bugfix: Stream.h: added a missing divide by BytesPerSample in
573     GetWriteSpace(). Since this function is currently only used in
574     the stream's qsort() compare function, it didn't trigger any
575     bugs.
576     - Resampler.h, Synthesizer.h: cubic interpolation now works in
577     24bit mode too. Faster method to read 24bit words on little
578     endian machines (x86): replaced 3 byte reads + shifts with a 1
579     unaligned 32bit read and shift
580     - experimental support for MS Windows (MIDI input via MME, AUDIO
581     output via ASIO)
582     - made handling of SIGINT signal (Ctrl-C) a bit more robust
583 iliev 1541 - support for monitoring the total number of active disk streams
584     (new LSCP commands: GET TOTAL_STREAM_COUNT,
585     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
586 persson 1455
587 senoner 1500 * AUDIO driver:
588 persson 1534 - added Windows ASIO low latency audio driver
589 senoner 1500
590 senoner 1485 * MIDI driver:
591 schoenebeck 1495 - added MME Windows MIDI driver
592 senoner 1485
593 schoenebeck 1471 * LSCP server:
594     - added support for Windows style path / filenames, however with
595     forward slash path separators instead of backslash
596     (i.e. "C:/foo/bar.gig")
597 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
598     apostrophes as well
599 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
600     "LIST FILE INSTRUMENTS <file>" and
601     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
602     about an arbitrary instrument file on the system where the sampler is
603     running on
604 schoenebeck 1471
605 schoenebeck 1424 Version 0.5.0 (15 October 2007)
606 schoenebeck 947
607 schoenebeck 1065 * packaging changes:
608 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
609     API header files anymore
610 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
611     the Doxygen API documentation (explicitly listed in Doxyfile.in)
612 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
613     capable to execute our autoconf environment, thus no need anymore
614     to maintain the compile time configuration file (osx/version.h) for
615     OSX manually (patch by Toshi Nagata)
616 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
617     parameters
618 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
619     C++ API header files, all implementation internal global definitions
620     are now in global_private.h
621     - atomic.h is not exposed to the C++ API anymore
622     - no need to include config.h anymore for using LS's API header files
623     - fixed warnings in API doc generation
624 schoenebeck 1065
625 schoenebeck 947 * general changes:
626     - replaced the old, confusing MIDI program change mechanism by a
627     flexible MIDI instrument mapper which allows to map arbitrary
628 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
629 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
630     loaded on the respective channel when such MIDI program change
631     messages arrive, beside that, each entry allows to define a life-time
632     strategy for the instrument, so the user can define whether the
633     instrument should i.e. be permanently loaded (to be able to switch
634     quickly among sounds) or i.e. loaded just on demand when the
635     respective program change arrives (to safe RAM space), as well as a
636     global volume factor for each entry, so the user can adjust the volume
637     dynamic of his mapped instrument collection without having to modify
638 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
639     MIDI instrument maps and assign each sampler channel individually
640     a certain map, so that i.e. separation of normal instruments and
641     drumkits is possible
642 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
643     MIDI instrument maps, MIDI instruments, FX sends, global volume.
644 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
645     due to a constant size RingBuffer FIFO which is now replaced by a
646     dynamic (unlimited) size std::list FIFO
647 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
648     output channels for being processed by external effect processors
649     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
650     controllers
651 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
652 iliev 1130 - Implemented new, improved notification system
653 schoenebeck 1149 - fixed compilation errors regarding OSX
654     (patch by Toshi Nagata)
655 iliev 1161 - implemented instruments database
656 iliev 1345 - added support for escape sequences to the instruments database
657 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
658     within the sampler's process (by using instrument editor plugins),
659     you'll notice the new "Registered instrument editors:" message on
660 schoenebeck 1407 startup, added a new LSCP command:
661     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
662 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
663     given sampler channel, the plugin path can be overridden at compile
664     time with ./configure --enable-plugin-dir=/some/dir
665 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
666     in the sampler's process to safely edit instruments while playing
667     without a crash (hopefully) by either suspending single regions
668     wherever possible or if unavoidable whole engine(s)
669 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
670     policy and priority on thread level, set a minimum stack size for
671     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
672     threads simply inherited properties of starting thread instead of
673     setting their own policy and priority
674 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
675     main process did not wait for the stack trace process to finish
676     its output
677 persson 1248 - fixed some minor memory leaks
678 schoenebeck 1259 - reenabled assembly features support, at the moment only for
679     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
680 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
681     register, to avoid relocations in the text segment at runtime)
682 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
683 schoenebeck 947
684     * MIDI driver:
685     - dispatch bank select (MSB and LSB) messages
686    
687 schoenebeck 1049 * audio driver:
688     - the ALSA audio output driver parameters now reflect the correct
689     parameter value ranges for the respective selected sound card
690     (patch by Till Wimmer, a bit fixed and extended)
691    
692 persson 951 * Gigasampler format engine:
693     - if a filter is used and EG2 finishes before EG1, let the voice
694     die when EG2 has finished (this fixes a problem with clicks and
695     voice starvation for some gigs)
696 persson 1038 - playback is no longer disabled during instrument loading
697     - all notes playing on a channel that changes its instrument keep
698     playing with the old instrument until they get a note off
699     command
700 persson 1039 - EG fix: a release value of zero could cause noises or crash
701 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
702 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
703     above max sustain level, which means that there is a decay phase
704     even if sustain is 100%
705 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
706     noises or crashes
707 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
708 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
709     supplied to the configure script (fixes #46)
710 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
711     instead of a fix value
712 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
713     127 (solo mode) only kill voices if the respective mode really
714     changed
715 persson 951
716 schoenebeck 1244 * LSCP server:
717     - fixed compile time error for old Bison versions
718     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
719 schoenebeck 1245 - parser now supports extended ASCII character set
720     (up to ASCII code 255, i.e. includes now umlauts and accents)
721     - filename arguments in LSCP commands now allow to use escape
722     sequences, that is directly literal as one of: \', \", \\, \n, \r,
723     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
724     code value like \xf2) (fixes bug #24)
725 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
726     least one of their text-based parameters (i.e. name, description):
727     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
728     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
729     "SET DB_INSTRUMENT_DIRECTORY NAME",
730     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
731     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
732     "FIND DB_INSTRUMENT_DIRECTORIES"
733 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
734     occured, the unexpected character and the actually expected, possible
735     character(s), the latter only if less than 5 possibilities)
736 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
737     settings
738 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
739     of strings were treated as being one string containing commas
740     (fixes #57)
741 schoenebeck 1244
742 iliev 959 * Bug fixes:
743     - fixed crash occurring on certain LSCP scripts (Bug 39)
744 persson 1038 - another thread safety fix for lscp "load engine" and "set
745     channel audio output device"
746 iliev 1283 - fixed a crash which occurs when reassigning the same engine
747     on a sampler channel with connected MIDI device
748 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
749     device connected to a sampler channel to number less then or equal
750     to the index of the port to which the sampler channel is connected.
751 iliev 1296 - The previous bindings were not been disconnected when altering
752     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
753     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
754 iliev 1297 - The active stream/voice count statistic was incorrect.
755 iliev 1298 - notification events were not been sent for some sampler
756     channel changes
757 iliev 1305 - added default min and max values to restrict the number of allowed
758     audio output channels and MIDI input ports
759 iliev 1306 - the connection to the PCM interface is now closed when destroying
760     an audio output device
761 schoenebeck 1332 - files with slash in their path or filename could not be loaded
762 iliev 959
763 schoenebeck 1221 * test cases:
764     - updated and fixed (haven't been touched in a while)
765    
766 schoenebeck 937 Version 0.4.0 (24 November 2006)
767 persson 696
768 schoenebeck 697 * packaging changes:
769 capela 868 - changed deprecated copyright attribute to license; added ldconfig
770     to post-(un)install steps; added devel package for liblinuxsampler;
771     to linuxsampler.spec (RPM)
772 schoenebeck 697 - install necessary development header files for allowing 3rd party
773     applications to link against liblinuxsampler
774     - liblinuxsampler's API documentation can be generated with 'make docs'
775     (Doxygen required)
776 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
777     implementation (currently either an integer math solution or a
778     di-harmonic approximation), automatic detection can be overriden
779     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
780     configure script argument though (mandatory for cross-compilation)
781 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
782     provided some on his own (as CXXFLAGS)
783 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
784     messages
785 schoenebeck 852 - added compile time options to allow disabling the various audio and
786     MIDI drivers
787 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
788     (patch by Ebrahim Mayat)
789 schoenebeck 697
790 persson 696 * Gigasampler format engine:
791 schoenebeck 738 - extensive synthesis optimization
792     (reimplementation of EGs and LFO(s), removed synthesis parameter
793     prerendering and the synthesis parameter matrix in general, splitting
794     each audio fragment into subfragments now where each subfragment uses
795 persson 830 constant pitch and filter coefficients. The volume coefficient is
796     linearly interpolated inside a subfragment, unless
797     --disable-interpolate-volume is set.)
798 persson 696 - fine tuning of the EG modulation parameters
799 persson 729 - improved filter cutoff calculation by adding support for the
800     following gig parameters: Cutoff freq (used when no cutoff
801     controller is defined), Control invert, Minimum cutoff, Velocity
802 persson 791 curve and Velocity range. The keyboard tracking now scales
803     cutoff frequency instead of resonance.
804 persson 877 - added support for gig parameter Resonance.
805 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
806 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
807     which can be overridden with --enable-global-attenuation
808 persson 783 - EG fixes: made the length of "attack hold" stage more
809     accurate. Release stage can now start before attack stage
810 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
811     time now has a minimal value to prevent clicks.
812 persson 799 - fixed pitch changes larger than one octave
813 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
814     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
815     all modes can be altered via standard GM messages, that is CC5 for
816     altering portamento time, CC65 for enabling / disabling portamento
817     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
818 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
819     parameter) and crossfade
820 persson 831 - added support for the "attenuation controller threshold" gig
821     parameter
822 persson 832 - added smoothing of volume changes caused by control change
823     messages
824 persson 865 - sample loop parameters are now taken from the DimensionRegion
825     instead of the wave chunk
826     - fixed keyswitching for v3 gigs with a number of keyswitch splits
827     not equal to a power of two
828 persson 877 - reimplementation of the filter algorithm. The new filter is more
829     accurate and supports all gig filter types, including bandreject
830     and lowpass turbo.
831 persson 903 - real support for 24 bit samples - samples are not truncated to
832     16 bits anymore
833     - support for aftertouch (channel pressure, not polyphonic
834     aftertouch)
835 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
836     amplifying from 0)
837 persson 696
838 schoenebeck 711 * LSCP server:
839     - fixed application exit on broken pipe error (fixes bug #20)
840 iliev 793 - fixed the notification messages delay due to lack of
841     network activity (fixes bug #26)
842 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
843     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
844 schoenebeck 711
845 schoenebeck 838 * audio driver:
846     - added aRts audio output driver (by no means RT safe)
847    
848 schoenebeck 775 * MIDI driver:
849     - fixed legacy sysex code which caused dispatching of MIDI SysEx
850     messages several times instead of once
851 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
852     for events (i.e. for offline rendering based MIDI drivers)
853 persson 922 - added checks for bad MIDI data
854 schoenebeck 775
855 schoenebeck 900 * linuxsampler application:
856     - show available sampler engine types on startup
857    
858 schoenebeck 705 * general changes:
859     - support for muting sampler channels and solo mode of the same, two new
860     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
861     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
862     introduced for this, the behavior is the same like on a mixer console
863 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
864     --enable-process-muted-channels which can be used to enable the
865     processing of muted channels.
866 iliev 777 - support for sostenuto pedal
867 iliev 779 - support for monitoring the total number of active voices
868 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
869     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
870 persson 835 - fixed some memory management errors
871 persson 841 - fixed some concurrency problems that could lead to crashes when
872     LSCP commands were executed
873 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
874     sampler channel (fixes bug #36)
875 schoenebeck 705
876 schoenebeck 692 Version 0.3.3 (15 July 2005)
877 schoenebeck 686
878     * packaging changes:
879     - fixed compilation with gcc 4.0
880    
881 schoenebeck 687 * Gigasampler format engine:
882     - LFO preprocessing was performed even though the respective LFO was
883     disabled by the instrument patch (minor efficiency fix)
884 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
885     for volume ramp downs in the same fragment (needed for current voice
886     stealing implementation) then simply inform the user with a warning
887     about possible click sounds and reduce the volume ramp down
888     appropriately instead of cancelling the audio device connection
889 schoenebeck 687
890 schoenebeck 677 Version 0.3.2 (24 June 2005)
891 schoenebeck 609
892     * packaging changes:
893     - updated autotools build files to compile on OS X
894     (conditional compilation of CoreMIDI and MidiShare drivers)
895 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
896     './configure --disable-asm' (definitely not recommended)
897 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
898     - require automake (>= 1.5) for 'make -f Makefile.cvs'
899     (due to 'dist-bzip2' automake option)
900 schoenebeck 649
901     * Gigasampler format engine:
902     - support for the gig parameters for "release velocity response" curves
903     - fine tuning of the EGADSR envelope
904     - volume of release triggered samples now depends on note-on velocity,
905     note length and gig parameter "release trigger decay" instead of
906     note-off velocity.
907 schoenebeck 663 - revised voice stealing
908     (fixes crash and endless loop caused by voice stealing)
909 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
910 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
911     instead of when the respective voice is actually launched
912     (fixes undefined behavior if stolen voices belonged to a key group -
913     this case was followed by a "killed voice survived" error message)
914 schoenebeck 669 - fixed minor issue with null/silence samples
915     (those stole voices even though they don't need a voice at all which
916     resulted in "voice stealing didn't work out" messages)
917 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
918     instrument or audio output device change
919 schoenebeck 654
920 schoenebeck 620 * LSCP server:
921 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
922 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
923 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
924 schoenebeck 609
925 schoenebeck 668 * linuxsampler application:
926     - added command line parameters --lscp-addr and --lscp-port to override
927     default IP address and port of LSCP server
928    
929 schoenebeck 579 Version 0.3.1 (24 May 2005)
930    
931     * initial release
