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:

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

25 persson 2086
26     * general changes:
27 iliev 2012 - Refactoring: moved the independent code from
28     the Gigasampler format engine to base classes
29 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
30     respective profiling code is currently broken
31 schoenebeck 2053 - Introduced support for optional environment variable
32     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
33     where the sampler shall look for instrument editor plugins
34     (patch by Luis Garrido, slightly modified).
35 schoenebeck 2121 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
36     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
37     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
38     note (in this implementation of the sampler its simply hard routed to
39     the 1st effect send of the sampler channel, no matter what the actual
40     effect type is)
41     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
42     note (in this implementation of the sampler its simply hard routed to
43     the 2nd effect send of the sampler channel, no matter what the actual
44     effect type is)
45 schoenebeck 2124 - implemented support for internal LADSPA effects
46 schoenebeck 2140 - raised limit of program change queue from 100 to 512
47     (as suggested by Alex Stone)

50 iliev 2306 - added command line option --exec-after-init
51 schoenebeck 2330 - Introduced new C++ API method:
52     EngineChannel::InstrumentFileName(int index)
53     allowing to retrieve the whole list of files used for the loaded
54     instrument on an engine channel (a.k.a. part). Some GigaStudio
55     instruments for example are splitted over several files like
56     "Foo.gig", "Foo.gx01", "Foo.gx02", ...
57 iliev 2012

341 schoenebeck 1599
342 schoenebeck 1639 * packaging changes:
343     - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
344     causing e.g. the libgig test to fail when
345     "./configure --disable-jack-driver" was used
346     (patch by Alexis Ballier)
347 persson 1713 - fixed compilation with gcc 4.3

354 persson 1897 - Windows: look for editor plugins and Fantasia using base
355 schoenebeck 1928 directory of liblinuxsampler dll (look in the same directory and one
356     directory above)
357 persson 1899 - configure script fix: removed unconditional use of SSE
358 persson 1923 - fixed building with sqlite installed in a non-standard directory
359 persson 1931 - when cross-compiling, don't try to create instruments.db
360     - fix for new mingw-w64 version, which has usleep
361 schoenebeck 1639
362 schoenebeck 1601 * general changes:
363     - bugfix: on some POSIX systems instrument editor plugins refused to
364     load as we used a non-portable Linux specific struct field
365     (fixes bug #70, patch by Ronald Baljeu)
366 schoenebeck 1602 - fixed endless loop which occured when loading an instrument editor
367     plugin DLL on Windows systems failed
368 persson 1644 - fixed memory leaks that occurred when liblinuxsampler was unloaded
369     - optimized the SynchronizedConfig class so it doesn't wait
370     unnecessarily long after an update
371 schoenebeck 1653 - added support for notifying instrument editors on note-on / note-off
372     events (e.g. to highlight the pressed keys on the virtual keyboard
373     of gigedit)
374 schoenebeck 1659 - added support for triggering notes by instrument editors (see above)
375 schoenebeck 1653 - be verbose on DLL load errors (on Linux)
376 schoenebeck 1681 - fixed di-harmonic triangle LFO implementation (this LFO implementation
377     is only used by very few systems, most pick the int math
378     implementation, which is usually faster)
379 persson 1748 - fixes for audio drivers with varying buffer sizes
380 persson 1777 - experimental support for running LinuxSampler as a DSSI, LV2 and
381     VST plugin
382 iliev 1789 - notification events for stream/voice count statistics are now sent

384 persson 1790 - added memory ordering constraints to improve stability on
385     multi-core and multi-cpu systems
386 schoenebeck 1800 - maximum voices and disk streams can now be altered at runtime
387 persson 1825 - fixed CPU feature detection on x86_64 (maybe fixes #108)
388 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
389     be switched on by command line option "--stacktrace" (the automatic
390     stacktrace mechanism seems to be broken on most systems at the moment)
391 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
392     a pointer to the launched InstrumentEditor object
393 schoenebeck 1876 - added optional 3rd party user data parameter for following
394     liblinuxsampler C++ API methods: InstrumentEditor::Main(),
395     InstrumentEditor::Launch(),
396     InstrumentManager::LaunchInstrumentEditor()
397 persson 1887 - theoretical fix: made SynchronizedConfig follow C++0x memory
398     model more strictly
399 persson 1895 - fixes for using large audio device buffers
400 persson 1951 - Windows: add the installation directory to the DLL search path

402     gigedit on systems with other GTK versions installed)
403 schoenebeck 1601
404 schoenebeck 1599 * audio driver:
405     - removed the nonsense audio channel constraint (which was hard coded to
406     max. 100 audio channels) for most audio drivers
407 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
408     opposed to the LSCP specs
409 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
410     reflected the wrong value
411 persson 1644 - fixed a memory management bug in ASIO driver
412 persson 1748 - Makefile fix: JACK_CFLAGS wasn't used
413 persson 1777 - JACK: use jack_client_open instead of the deprecated
414 persson 1748 jack_client_new
415 iliev 1829 - added (experimental) CoreAudio driver
416 persson 1888 - applied old fixes to the ASIO driver that were included in the
417     previous binary release but accidentally never committed to CVS
418     (fixes #117)
419 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
420     win64)
421 persson 1895 - VST: added support for sample rate and buffer size changes
422     - VST: close editor (Fantasia) when the VST is removed
423 persson 1908 - VST: avoid opening Fantasia more than once for each VST instance

427     stereo
428 persson 1922 - added channel routing, fxsends and midi maps to the settings
429     stored in the plugin state
430 schoenebeck 1930 - performance optimization of AudioChannel::MixTo() and
431     AudioChannel::CopyTo() methods using GCC vector exensions
432     (if available)
433 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
434     exception when getting parameters from a disconnected device
435 schoenebeck 1599
436 persson 1651 * MIDI driver:
437     - added JACK MIDI driver
438 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
439     want to (mis)use it for some purpose ("fixed" in all current MIDI
440     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
441 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
442 persson 1887 CoreMidi or AU
443 persson 1889 - fixed mingw-w64 compilation error in MME driver
444 persson 1924 - made program change handling in MIDI thread real-time safe by
445     moving the logic to a non-RT thread
446 persson 1951 - fixed minor memory leak in ALSA driver
447 persson 1651
448 schoenebeck 1604 * instruments database:
449 iliev 1603 - avoid time consuming samples scanning when adding instruments
450     to the instruments database
451 iliev 1727 - added support for handling lost files in the instruments database
452 iliev 1781 - Implemented option for adding instruments in separate directories
453     in the instruments database
454     (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
455 persson 1908 - work-around for missing fnmatch function on Windows to make
456     instrument database compilable
457 schoenebeck 1930 - added instrument database support on Windows
458     works with both standalone mode and VST plugin.
459     the instruments DB file is located in
460     %USERPROFILE%\.linuxsampler\instruments.db which allows different
461     databases for each windows user
462     if no DB is present it automatically creates the .linuxsampler subdir
463     and then creates an empty DB
464 persson 1943 - fixed recursive import, which was broken on Windows
465 iliev 1603
466 persson 1644 * Gigasampler format engine:
467     - fixed a memory leak that could happen when a channel was deleted
468     while notes were playing
469 persson 1646 - made it possible to load an instrument even if the audio thread
470     isn't running
471 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
472     enough for piano gigs with pedal noise samples
473 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
474     respective FX send MIDI controller was used
475 schoenebeck 1724 - added support for GM global device volume SysEx message
476 schoenebeck 1762 (can be selected at compile time to either apply globally to the
477     whole sampler [default] or only to the sampler channels that are
478     connected to the respective MIDI input port the SysEx message arrived
479     on)
480 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
481     sometimes wrongly killed in the same buffer, causing no sound to
482     be played
483 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
484     which is usally used to switch a part between chromatic sounds and
485     drumkit sounds (as opposed to their common default setting of MIDI
486     part 10 being a drumkit part and all other ones chromatic parts), in
487     LS however one can switch between the first 16 MIDI instrument maps
488     defined for the sampler
489 persson 1764 - made it possible to create multiple sample channels even if the
490     audio thread isn't running
491 persson 1844 - fixed crash when removing channel with active voices (#116)
492 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
493     un-cache the respective sample if it's really not used by any
494     sampler engine anymore
495     - re-cache samples in case they were changed by an instrument editor,
496     e.g. when a sample was added while playing (#82)
497 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
498     same time stamp as the voice's note-on event and occured both in the
499     same audio fragment cycle (fixes bug #112)
500 persson 1858 - added support for the "fine tune" and "pitch bend range"
501     instrument-level gig parameters
502     - fixed minor artifacts in pitch bend handling
503 schoenebeck 1860 - added support for GS Reset SysEx message
504 persson 1862 - allow gig files to use unlimited downward pitch shifting
505     - added a limit check for upward pitch shifting
506 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
507     note was silent
508 persson 1923 - fixed crash happening when a pitch bend event arrived at the
509     same time a new instrument was loading
510 persson 1644
511 schoenebeck 1687 * LSCP server:
512     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
513     react on MIDI data arriving on certain sampler channels (so far only
514     Note-On and Note-Off events are sent via this LSCP event)
515 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
516     react on MIDI data arriving on certain MIDI input devices (so far only
517     Note-On and Note-Off events are sent via this LSCP event)
518 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
519     SET DB_INSTRUMENT FILE_PATH
520 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
521     frontends to send MIDI messages to specific sampler channel
522     - added two additional fields to GET FILE INSTRUMENT INFO command -
523     KEY_BINDINGS and KEYSWITCH_BINDINGS
524 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
525     was incorrect
526 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
527 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
528     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
529     be triggered respectively
530     - added new LSCP command "SET STREAMS" to globally alter the maximum
531     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
532     which will be triggered respectively
533 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
534     a gigedit file dialog is opened)
535 iliev 1848 - close all connections when LSCPServer is deleted
536 iliev 1882 - hard close of all sockets on exit
537 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
538     driver
539 schoenebeck 1687
540 iliev 1761 * Bug fixes:
541     - fixed a crash which occurs when removing a sampler channel waiting
542     to start instrument loading after another channel
543 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
544     instrument loading in progress (bug #113)
545 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
546     instrument with PERSISTENT load mode
547 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
548     - fixed memory leaks when issuing the following LSCP commands:
549     GET AUDIO_OUTPUT_DRIVER INFO
550     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
551     GET MIDI_INPUT_DRIVER INFO
552     GET MIDI_INPUT_DRIVER_PARAMETER INFO
553     - fixed possible compilation error when sqlite is not present
554 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
555 iliev 1847 - fixed crash when changing the audio output device of a sampler
556     channel with loaded instrument and start playing notes
557 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
558 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
559     PowerPC, which probably could cause crashes on that platform
560 persson 1889 - fixed a memory management error which could cause a crash when a
561     plugin was unloaded
562 persson 1896 - bugfix: two private structs had the same name, which could cause
563     problems if the linker chose the wrong constructor
564 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
565     Windows
566 iliev 1761
567    
568 schoenebeck 1560 Version 0.5.1 (6 December 2007)
569 schoenebeck 1454
570     * packaging changes:
571     - added autoconf checks for pthread library
572     - added autoconf check for pthread bug found on certain NPTL-enabled
573     glibc versions (see Gentoo bug report #194076)
574 senoner 1502 - added autoconf checks for MS Windows
575 schoenebeck 1454
576 persson 1455 * general changes:
577     - bugfix: the thread used by an editor plugin didn't die when the
578     editor closed
579 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
580     out all the space. operator--() did not apply size_mask after
581     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
582     order to avoid problems with the _NonVolatileReader functions.
583     - bugfix: Stream.h: added a missing divide by BytesPerSample in
584     GetWriteSpace(). Since this function is currently only used in
585     the stream's qsort() compare function, it didn't trigger any
586     bugs.
587     - Resampler.h, Synthesizer.h: cubic interpolation now works in
588     24bit mode too. Faster method to read 24bit words on little
589     endian machines (x86): replaced 3 byte reads + shifts with a 1
590     unaligned 32bit read and shift
591     - experimental support for MS Windows (MIDI input via MME, AUDIO
592     output via ASIO)
593     - made handling of SIGINT signal (Ctrl-C) a bit more robust
594 iliev 1541 - support for monitoring the total number of active disk streams
595     (new LSCP commands: GET TOTAL_STREAM_COUNT,
596     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
597 persson 1455
598 senoner 1500 * AUDIO driver:
599 persson 1534 - added Windows ASIO low latency audio driver
600 senoner 1500
601 senoner 1485 * MIDI driver:
602 schoenebeck 1495 - added MME Windows MIDI driver
603 senoner 1485
604 schoenebeck 1471 * LSCP server:
605     - added support for Windows style path / filenames, however with
606     forward slash path separators instead of backslash
607     (i.e. "C:/foo/bar.gig")
608 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
609     apostrophes as well
610 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
611     "LIST FILE INSTRUMENTS <file>" and
612     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
613     about an arbitrary instrument file on the system where the sampler is
614     running on
615 schoenebeck 1471
616 schoenebeck 1424 Version 0.5.0 (15 October 2007)
617 schoenebeck 947
618 schoenebeck 1065 * packaging changes:
619 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
620     API header files anymore
621 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
622     the Doxygen API documentation (explicitly listed in Doxyfile.in)
623 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
624     capable to execute our autoconf environment, thus no need anymore
625     to maintain the compile time configuration file (osx/version.h) for
626     OSX manually (patch by Toshi Nagata)
627 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
628     parameters
629 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
630     C++ API header files, all implementation internal global definitions
631     are now in global_private.h
632     - atomic.h is not exposed to the C++ API anymore
633     - no need to include config.h anymore for using LS's API header files
634     - fixed warnings in API doc generation
635 schoenebeck 1065
636 schoenebeck 947 * general changes:
637     - replaced the old, confusing MIDI program change mechanism by a
638     flexible MIDI instrument mapper which allows to map arbitrary
639 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
640 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
641     loaded on the respective channel when such MIDI program change
642     messages arrive, beside that, each entry allows to define a life-time
643     strategy for the instrument, so the user can define whether the
644     instrument should i.e. be permanently loaded (to be able to switch
645     quickly among sounds) or i.e. loaded just on demand when the
646     respective program change arrives (to safe RAM space), as well as a
647     global volume factor for each entry, so the user can adjust the volume
648     dynamic of his mapped instrument collection without having to modify
649 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
650     MIDI instrument maps and assign each sampler channel individually
651     a certain map, so that i.e. separation of normal instruments and
652     drumkits is possible
653 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
654     MIDI instrument maps, MIDI instruments, FX sends, global volume.
655 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
656     due to a constant size RingBuffer FIFO which is now replaced by a
657     dynamic (unlimited) size std::list FIFO
658 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
659     output channels for being processed by external effect processors
660     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
661     controllers
662 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
663 iliev 1130 - Implemented new, improved notification system
664 schoenebeck 1149 - fixed compilation errors regarding OSX
665     (patch by Toshi Nagata)
666 iliev 1161 - implemented instruments database
667 iliev 1345 - added support for escape sequences to the instruments database
668 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
669     within the sampler's process (by using instrument editor plugins),
670     you'll notice the new "Registered instrument editors:" message on
671 schoenebeck 1407 startup, added a new LSCP command:
672     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
673 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
674     given sampler channel, the plugin path can be overridden at compile
675     time with ./configure --enable-plugin-dir=/some/dir
676 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
677     in the sampler's process to safely edit instruments while playing
678     without a crash (hopefully) by either suspending single regions
679     wherever possible or if unavoidable whole engine(s)
680 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
681     policy and priority on thread level, set a minimum stack size for
682     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
683     threads simply inherited properties of starting thread instead of
684     setting their own policy and priority
685 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
686     main process did not wait for the stack trace process to finish
687     its output
688 persson 1248 - fixed some minor memory leaks
689 schoenebeck 1259 - reenabled assembly features support, at the moment only for
690     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
691 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
692     register, to avoid relocations in the text segment at runtime)
693 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
694 schoenebeck 947
695     * MIDI driver:
696     - dispatch bank select (MSB and LSB) messages
697    
698 schoenebeck 1049 * audio driver:
699     - the ALSA audio output driver parameters now reflect the correct
700     parameter value ranges for the respective selected sound card
701     (patch by Till Wimmer, a bit fixed and extended)
702    
703 persson 951 * Gigasampler format engine:
704     - if a filter is used and EG2 finishes before EG1, let the voice
705     die when EG2 has finished (this fixes a problem with clicks and
706     voice starvation for some gigs)
707 persson 1038 - playback is no longer disabled during instrument loading
708     - all notes playing on a channel that changes its instrument keep
709     playing with the old instrument until they get a note off
710     command
711 persson 1039 - EG fix: a release value of zero could cause noises or crash
712 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
713 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
714     above max sustain level, which means that there is a decay phase
715     even if sustain is 100%
716 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
717     noises or crashes
718 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
719 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
720     supplied to the configure script (fixes #46)
721 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
722     instead of a fix value
723 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
724     127 (solo mode) only kill voices if the respective mode really
725     changed
726 persson 951
727 schoenebeck 1244 * LSCP server:
728     - fixed compile time error for old Bison versions
729     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
730 schoenebeck 1245 - parser now supports extended ASCII character set
731     (up to ASCII code 255, i.e. includes now umlauts and accents)
732     - filename arguments in LSCP commands now allow to use escape
733     sequences, that is directly literal as one of: \', \", \\, \n, \r,
734     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
735     code value like \xf2) (fixes bug #24)
736 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
737     least one of their text-based parameters (i.e. name, description):
738     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
739     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
740     "SET DB_INSTRUMENT_DIRECTORY NAME",
741     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
742     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
743     "FIND DB_INSTRUMENT_DIRECTORIES"
744 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
745     occured, the unexpected character and the actually expected, possible
746     character(s), the latter only if less than 5 possibilities)
747 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
748     settings
749 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
750     of strings were treated as being one string containing commas
751     (fixes #57)
752 schoenebeck 1244
753 iliev 959 * Bug fixes:
754     - fixed crash occurring on certain LSCP scripts (Bug 39)
755 persson 1038 - another thread safety fix for lscp "load engine" and "set
756     channel audio output device"
757 iliev 1283 - fixed a crash which occurs when reassigning the same engine
758     on a sampler channel with connected MIDI device
759 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
760     device connected to a sampler channel to number less then or equal
761     to the index of the port to which the sampler channel is connected.
762 iliev 1296 - The previous bindings were not been disconnected when altering
763     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
764     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
765 iliev 1297 - The active stream/voice count statistic was incorrect.
766 iliev 1298 - notification events were not been sent for some sampler
767     channel changes
768 iliev 1305 - added default min and max values to restrict the number of allowed
769     audio output channels and MIDI input ports
770 iliev 1306 - the connection to the PCM interface is now closed when destroying
771     an audio output device
772 schoenebeck 1332 - files with slash in their path or filename could not be loaded
773 iliev 959
774 schoenebeck 1221 * test cases:
775     - updated and fixed (haven't been touched in a while)
776    
777 schoenebeck 937 Version 0.4.0 (24 November 2006)
778 persson 696
779 schoenebeck 697 * packaging changes:
780 capela 868 - changed deprecated copyright attribute to license; added ldconfig
781     to post-(un)install steps; added devel package for liblinuxsampler;
782     to linuxsampler.spec (RPM)
783 schoenebeck 697 - install necessary development header files for allowing 3rd party
784     applications to link against liblinuxsampler
785     - liblinuxsampler's API documentation can be generated with 'make docs'
786     (Doxygen required)
787 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
788     implementation (currently either an integer math solution or a
789     di-harmonic approximation), automatic detection can be overriden
790     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
791     configure script argument though (mandatory for cross-compilation)
792 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
793     provided some on his own (as CXXFLAGS)
794 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
795     messages
796 schoenebeck 852 - added compile time options to allow disabling the various audio and
797     MIDI drivers
798 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
799     (patch by Ebrahim Mayat)
800 schoenebeck 697
801 persson 696 * Gigasampler format engine:
802 schoenebeck 738 - extensive synthesis optimization
803     (reimplementation of EGs and LFO(s), removed synthesis parameter
804     prerendering and the synthesis parameter matrix in general, splitting
805     each audio fragment into subfragments now where each subfragment uses
806 persson 830 constant pitch and filter coefficients. The volume coefficient is
807     linearly interpolated inside a subfragment, unless
808     --disable-interpolate-volume is set.)
809 persson 696 - fine tuning of the EG modulation parameters
810 persson 729 - improved filter cutoff calculation by adding support for the
811     following gig parameters: Cutoff freq (used when no cutoff
812     controller is defined), Control invert, Minimum cutoff, Velocity
813 persson 791 curve and Velocity range. The keyboard tracking now scales
814     cutoff frequency instead of resonance.
815 persson 877 - added support for gig parameter Resonance.
816 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
817 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
818     which can be overridden with --enable-global-attenuation
819 persson 783 - EG fixes: made the length of "attack hold" stage more
820     accurate. Release stage can now start before attack stage
821 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
822     time now has a minimal value to prevent clicks.
823 persson 799 - fixed pitch changes larger than one octave
824 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
825     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
826     all modes can be altered via standard GM messages, that is CC5 for
827     altering portamento time, CC65 for enabling / disabling portamento
828     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
829 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
830     parameter) and crossfade
831 persson 831 - added support for the "attenuation controller threshold" gig
832     parameter
833 persson 832 - added smoothing of volume changes caused by control change
834     messages
835 persson 865 - sample loop parameters are now taken from the DimensionRegion
836     instead of the wave chunk
837     - fixed keyswitching for v3 gigs with a number of keyswitch splits
838     not equal to a power of two
839 persson 877 - reimplementation of the filter algorithm. The new filter is more
840     accurate and supports all gig filter types, including bandreject
841     and lowpass turbo.
842 persson 903 - real support for 24 bit samples - samples are not truncated to
843     16 bits anymore
844     - support for aftertouch (channel pressure, not polyphonic
845     aftertouch)
846 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
847     amplifying from 0)
848 persson 696
849 schoenebeck 711 * LSCP server:
850     - fixed application exit on broken pipe error (fixes bug #20)
851 iliev 793 - fixed the notification messages delay due to lack of
852     network activity (fixes bug #26)
853 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
854     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
855 schoenebeck 711
856 schoenebeck 838 * audio driver:
857     - added aRts audio output driver (by no means RT safe)
858    
859 schoenebeck 775 * MIDI driver:
860     - fixed legacy sysex code which caused dispatching of MIDI SysEx
861     messages several times instead of once
862 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
863     for events (i.e. for offline rendering based MIDI drivers)
864 persson 922 - added checks for bad MIDI data
865 schoenebeck 775
866 schoenebeck 900 * linuxsampler application:
867     - show available sampler engine types on startup
868    
869 schoenebeck 705 * general changes:
870     - support for muting sampler channels and solo mode of the same, two new
871     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
872     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
873     introduced for this, the behavior is the same like on a mixer console
874 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
875     --enable-process-muted-channels which can be used to enable the
876     processing of muted channels.
877 iliev 777 - support for sostenuto pedal
878 iliev 779 - support for monitoring the total number of active voices
879 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
880     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
881 persson 835 - fixed some memory management errors
882 persson 841 - fixed some concurrency problems that could lead to crashes when
883     LSCP commands were executed
884 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
885     sampler channel (fixes bug #36)
886 schoenebeck 705
887 schoenebeck 692 Version 0.3.3 (15 July 2005)
888 schoenebeck 686
889     * packaging changes:
890     - fixed compilation with gcc 4.0
891    
892 schoenebeck 687 * Gigasampler format engine:
893     - LFO preprocessing was performed even though the respective LFO was
894     disabled by the instrument patch (minor efficiency fix)
895 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
896     for volume ramp downs in the same fragment (needed for current voice
897     stealing implementation) then simply inform the user with a warning
898     about possible click sounds and reduce the volume ramp down
899     appropriately instead of cancelling the audio device connection
900 schoenebeck 687
901 schoenebeck 677 Version 0.3.2 (24 June 2005)
902 schoenebeck 609
903     * packaging changes:
904     - updated autotools build files to compile on OS X
905     (conditional compilation of CoreMIDI and MidiShare drivers)
906 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
907     './configure --disable-asm' (definitely not recommended)
908 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
909     - require automake (>= 1.5) for 'make -f Makefile.cvs'
910     (due to 'dist-bzip2' automake option)
911 schoenebeck 649
912     * Gigasampler format engine:
913     - support for the gig parameters for "release velocity response" curves
914     - fine tuning of the EGADSR envelope
915     - volume of release triggered samples now depends on note-on velocity,
916     note length and gig parameter "release trigger decay" instead of
917     note-off velocity.
918 schoenebeck 663 - revised voice stealing
919     (fixes crash and endless loop caused by voice stealing)
920 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
921 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
922     instead of when the respective voice is actually launched
923     (fixes undefined behavior if stolen voices belonged to a key group -
924     this case was followed by a "killed voice survived" error message)
925 schoenebeck 669 - fixed minor issue with null/silence samples
926     (those stole voices even though they don't need a voice at all which
927     resulted in "voice stealing didn't work out" messages)
928 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
929     instrument or audio output device change
930 schoenebeck 654
931 schoenebeck 620 * LSCP server:
932 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
933 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
934 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
935 schoenebeck 609
936 schoenebeck 668 * linuxsampler application:
937     - added command line parameters --lscp-addr and --lscp-port to override
938     default IP address and port of LSCP server
939    
940 schoenebeck 579 Version 0.3.1 (24 May 2005)
941    
942     * initial release
