* bugfix: instrument loading crashed for sfz and sf2 in Ardour (#176)
* more thread safety fixes for the instrument loading thread

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).
31 schoenebeck 2121 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
32     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
33     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
34     note (in this implementation of the sampler its simply hard routed to
35     the 1st effect send of the sampler channel, no matter what the actual
36     effect type is)
37     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
38     note (in this implementation of the sampler its simply hard routed to
39     the 2nd effect send of the sampler channel, no matter what the actual
40     effect type is)
41 schoenebeck 2124 - implemented support for internal LADSPA effects
42 schoenebeck 2140 - raised limit of program change queue from 100 to 512
43     (as suggested by Alex Stone)

48 persson 2043 * Gigasampler format engine:
49     - implemented the "round robin keyboard" dimension

51     dimension zones is not a power of two
52     - made round robin use a counter for each region instead of each
53     key
54    
55 schoenebeck 2047 * SFZ format engine:
56 iliev 2012 - Initial implementation (not usable yet)

343 schoenebeck 1928 directory of liblinuxsampler dll (look in the same directory and one
344     directory above)
345 persson 1899 - configure script fix: removed unconditional use of SSE
346 persson 1923 - fixed building with sqlite installed in a non-standard directory
347 persson 1931 - when cross-compiling, don't try to create instruments.db
348     - fix for new mingw-w64 version, which has usleep
349 schoenebeck 1639
350 schoenebeck 1601 * general changes:
351     - bugfix: on some POSIX systems instrument editor plugins refused to
352     load as we used a non-portable Linux specific struct field
353     (fixes bug #70, patch by Ronald Baljeu)
354 schoenebeck 1602 - fixed endless loop which occured when loading an instrument editor
355     plugin DLL on Windows systems failed
356 persson 1644 - fixed memory leaks that occurred when liblinuxsampler was unloaded
357     - optimized the SynchronizedConfig class so it doesn't wait
358     unnecessarily long after an update
359 schoenebeck 1653 - added support for notifying instrument editors on note-on / note-off
360     events (e.g. to highlight the pressed keys on the virtual keyboard
361     of gigedit)
362 schoenebeck 1659 - added support for triggering notes by instrument editors (see above)
363 schoenebeck 1653 - be verbose on DLL load errors (on Linux)
364 schoenebeck 1681 - fixed di-harmonic triangle LFO implementation (this LFO implementation
365     is only used by very few systems, most pick the int math
366     implementation, which is usually faster)
367 persson 1748 - fixes for audio drivers with varying buffer sizes
368 persson 1777 - experimental support for running LinuxSampler as a DSSI, LV2 and
369     VST plugin

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

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