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

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

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

333     (fixes bug #70, patch by Ronald Baljeu)
334 schoenebeck 1602 - fixed endless loop which occured when loading an instrument editor
335     plugin DLL on Windows systems failed
336 persson 1644 - fixed memory leaks that occurred when liblinuxsampler was unloaded
337     - optimized the SynchronizedConfig class so it doesn't wait
338     unnecessarily long after an update
339 schoenebeck 1653 - added support for notifying instrument editors on note-on / note-off
340     events (e.g. to highlight the pressed keys on the virtual keyboard
341     of gigedit)
342 schoenebeck 1659 - added support for triggering notes by instrument editors (see above)
343 schoenebeck 1653 - be verbose on DLL load errors (on Linux)
344 schoenebeck 1681 - fixed di-harmonic triangle LFO implementation (this LFO implementation
345     is only used by very few systems, most pick the int math
346     implementation, which is usually faster)
347 persson 1748 - fixes for audio drivers with varying buffer sizes
348 persson 1777 - experimental support for running LinuxSampler as a DSSI, LV2 and
349     VST plugin

353     multi-core and multi-cpu systems
354 schoenebeck 1800 - maximum voices and disk streams can now be altered at runtime
355 persson 1825 - fixed CPU feature detection on x86_64 (maybe fixes #108)
356 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
357     be switched on by command line option "--stacktrace" (the automatic
358     stacktrace mechanism seems to be broken on most systems at the moment)
359 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
360     a pointer to the launched InstrumentEditor object
361 schoenebeck 1876 - added optional 3rd party user data parameter for following
362     liblinuxsampler C++ API methods: InstrumentEditor::Main(),
363     InstrumentEditor::Launch(),
364     InstrumentManager::LaunchInstrumentEditor()
365 persson 1887 - theoretical fix: made SynchronizedConfig follow C++0x memory
366     model more strictly
367 persson 1895 - fixes for using large audio device buffers
368 persson 1951 - Windows: add the installation directory to the DLL search path

370     gigedit on systems with other GTK versions installed)
371 schoenebeck 1601
372 schoenebeck 1599 * audio driver:
373     - removed the nonsense audio channel constraint (which was hard coded to
374     max. 100 audio channels) for most audio drivers
375 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
376     opposed to the LSCP specs
377 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
378     reflected the wrong value
379 persson 1644 - fixed a memory management bug in ASIO driver
380 persson 1748 - Makefile fix: JACK_CFLAGS wasn't used
381 persson 1777 - JACK: use jack_client_open instead of the deprecated
382 persson 1748 jack_client_new
383 iliev 1829 - added (experimental) CoreAudio driver
384 persson 1888 - applied old fixes to the ASIO driver that were included in the
385     previous binary release but accidentally never committed to CVS
386     (fixes #117)
387 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
388     win64)
389 persson 1895 - VST: added support for sample rate and buffer size changes
390     - VST: close editor (Fantasia) when the VST is removed
391 persson 1908 - VST: avoid opening Fantasia more than once for each VST instance

395     stereo
396 persson 1922 - added channel routing, fxsends and midi maps to the settings
397     stored in the plugin state
398 schoenebeck 1930 - performance optimization of AudioChannel::MixTo() and
399     AudioChannel::CopyTo() methods using GCC vector exensions
400     (if available)
401 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
402     exception when getting parameters from a disconnected device
403 schoenebeck 1599
404 persson 1651 * MIDI driver:
405     - added JACK MIDI driver
406 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
407     want to (mis)use it for some purpose ("fixed" in all current MIDI
408     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
409 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
410 persson 1887 CoreMidi or AU
411 persson 1889 - fixed mingw-w64 compilation error in MME driver
412 persson 1924 - made program change handling in MIDI thread real-time safe by
413     moving the logic to a non-RT thread
414 persson 1951 - fixed minor memory leak in ALSA driver
415 persson 1651
416 schoenebeck 1604 * instruments database:
417 iliev 1603 - avoid time consuming samples scanning when adding instruments
418     to the instruments database
419 iliev 1727 - added support for handling lost files in the instruments database
420 iliev 1781 - Implemented option for adding instruments in separate directories
421     in the instruments database
422     (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
423 persson 1908 - work-around for missing fnmatch function on Windows to make
424     instrument database compilable
425 schoenebeck 1930 - added instrument database support on Windows
426     works with both standalone mode and VST plugin.
427     the instruments DB file is located in
428     %USERPROFILE%\.linuxsampler\instruments.db which allows different
429     databases for each windows user
430     if no DB is present it automatically creates the .linuxsampler subdir
431     and then creates an empty DB
432 persson 1943 - fixed recursive import, which was broken on Windows
433 iliev 1603
434 persson 1644 * Gigasampler format engine:
435     - fixed a memory leak that could happen when a channel was deleted
436     while notes were playing
437 persson 1646 - made it possible to load an instrument even if the audio thread
438     isn't running
439 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
440     enough for piano gigs with pedal noise samples
441 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
442     respective FX send MIDI controller was used
443 schoenebeck 1724 - added support for GM global device volume SysEx message
444 schoenebeck 1762 (can be selected at compile time to either apply globally to the
445     whole sampler [default] or only to the sampler channels that are
446     connected to the respective MIDI input port the SysEx message arrived
447     on)
448 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
449     sometimes wrongly killed in the same buffer, causing no sound to
450     be played
451 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
452     which is usally used to switch a part between chromatic sounds and
453     drumkit sounds (as opposed to their common default setting of MIDI
454     part 10 being a drumkit part and all other ones chromatic parts), in
455     LS however one can switch between the first 16 MIDI instrument maps
456     defined for the sampler
457 persson 1764 - made it possible to create multiple sample channels even if the
458     audio thread isn't running
459 persson 1844 - fixed crash when removing channel with active voices (#116)
460 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
461     un-cache the respective sample if it's really not used by any
462     sampler engine anymore
463     - re-cache samples in case they were changed by an instrument editor,
464     e.g. when a sample was added while playing (#82)
465 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
466     same time stamp as the voice's note-on event and occured both in the
467     same audio fragment cycle (fixes bug #112)
468 persson 1858 - added support for the "fine tune" and "pitch bend range"
469     instrument-level gig parameters
470     - fixed minor artifacts in pitch bend handling
471 schoenebeck 1860 - added support for GS Reset SysEx message
472 persson 1862 - allow gig files to use unlimited downward pitch shifting
473     - added a limit check for upward pitch shifting
474 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
475     note was silent
476 persson 1923 - fixed crash happening when a pitch bend event arrived at the
477     same time a new instrument was loading
478 persson 1644
479 schoenebeck 1687 * LSCP server:
480     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
481     react on MIDI data arriving on certain sampler channels (so far only
482     Note-On and Note-Off events are sent via this LSCP event)
483 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
484     react on MIDI data arriving on certain MIDI input devices (so far only
485     Note-On and Note-Off events are sent via this LSCP event)
486 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
487     SET DB_INSTRUMENT FILE_PATH
488 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
489     frontends to send MIDI messages to specific sampler channel
490     - added two additional fields to GET FILE INSTRUMENT INFO command -
491     KEY_BINDINGS and KEYSWITCH_BINDINGS
492 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
493     was incorrect
494 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
495 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
496     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
497     be triggered respectively
498     - added new LSCP command "SET STREAMS" to globally alter the maximum
499     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
500     which will be triggered respectively
501 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
502     a gigedit file dialog is opened)
503 iliev 1848 - close all connections when LSCPServer is deleted
504 iliev 1882 - hard close of all sockets on exit
505 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
506     driver
507 schoenebeck 1687
508 iliev 1761 * Bug fixes:
509     - fixed a crash which occurs when removing a sampler channel waiting
510     to start instrument loading after another channel
511 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
512     instrument loading in progress (bug #113)
513 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
514     instrument with PERSISTENT load mode
515 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
516     - fixed memory leaks when issuing the following LSCP commands:
517     GET AUDIO_OUTPUT_DRIVER INFO
518     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
519     GET MIDI_INPUT_DRIVER INFO
520     GET MIDI_INPUT_DRIVER_PARAMETER INFO
521     - fixed possible compilation error when sqlite is not present
522 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
523 iliev 1847 - fixed crash when changing the audio output device of a sampler
524     channel with loaded instrument and start playing notes
525 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
526 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
527     PowerPC, which probably could cause crashes on that platform
528 persson 1889 - fixed a memory management error which could cause a crash when a
529     plugin was unloaded
530 persson 1896 - bugfix: two private structs had the same name, which could cause
531     problems if the linker chose the wrong constructor
532 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
533     Windows
534 iliev 1761
535    
536 schoenebeck 1560 Version 0.5.1 (6 December 2007)
537 schoenebeck 1454
538     * packaging changes:
539     - added autoconf checks for pthread library
540     - added autoconf check for pthread bug found on certain NPTL-enabled
541     glibc versions (see Gentoo bug report #194076)
542 senoner 1502 - added autoconf checks for MS Windows
543 schoenebeck 1454
544 persson 1455 * general changes:
545     - bugfix: the thread used by an editor plugin didn't die when the
546     editor closed
547 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
548     out all the space. operator--() did not apply size_mask after
549     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
550     order to avoid problems with the _NonVolatileReader functions.
551     - bugfix: Stream.h: added a missing divide by BytesPerSample in
552     GetWriteSpace(). Since this function is currently only used in
553     the stream's qsort() compare function, it didn't trigger any
554     bugs.
555     - Resampler.h, Synthesizer.h: cubic interpolation now works in
556     24bit mode too. Faster method to read 24bit words on little
557     endian machines (x86): replaced 3 byte reads + shifts with a 1
558     unaligned 32bit read and shift
559     - experimental support for MS Windows (MIDI input via MME, AUDIO
560     output via ASIO)
561     - made handling of SIGINT signal (Ctrl-C) a bit more robust
562 iliev 1541 - support for monitoring the total number of active disk streams
563     (new LSCP commands: GET TOTAL_STREAM_COUNT,
564     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
565 persson 1455
566 senoner 1500 * AUDIO driver:
567 persson 1534 - added Windows ASIO low latency audio driver
568 senoner 1500
569 senoner 1485 * MIDI driver:
570 schoenebeck 1495 - added MME Windows MIDI driver
571 senoner 1485
572 schoenebeck 1471 * LSCP server:
573     - added support for Windows style path / filenames, however with
574     forward slash path separators instead of backslash
575     (i.e. "C:/foo/bar.gig")
576 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
577     apostrophes as well
578 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
579     "LIST FILE INSTRUMENTS <file>" and
580     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
581     about an arbitrary instrument file on the system where the sampler is
582     running on
583 schoenebeck 1471
584 schoenebeck 1424 Version 0.5.0 (15 October 2007)
585 schoenebeck 947
586 schoenebeck 1065 * packaging changes:
587 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
588     API header files anymore
589 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
590     the Doxygen API documentation (explicitly listed in Doxyfile.in)
591 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
592     capable to execute our autoconf environment, thus no need anymore
593     to maintain the compile time configuration file (osx/version.h) for
594     OSX manually (patch by Toshi Nagata)
595 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
596     parameters
597 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
598     C++ API header files, all implementation internal global definitions
599     are now in global_private.h
600     - atomic.h is not exposed to the C++ API anymore
601     - no need to include config.h anymore for using LS's API header files
602     - fixed warnings in API doc generation
603 schoenebeck 1065
604 schoenebeck 947 * general changes:
605     - replaced the old, confusing MIDI program change mechanism by a
606     flexible MIDI instrument mapper which allows to map arbitrary
607 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
608 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
609     loaded on the respective channel when such MIDI program change
610     messages arrive, beside that, each entry allows to define a life-time
611     strategy for the instrument, so the user can define whether the
612     instrument should i.e. be permanently loaded (to be able to switch
613     quickly among sounds) or i.e. loaded just on demand when the
614     respective program change arrives (to safe RAM space), as well as a
615     global volume factor for each entry, so the user can adjust the volume
616     dynamic of his mapped instrument collection without having to modify
617 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
618     MIDI instrument maps and assign each sampler channel individually
619     a certain map, so that i.e. separation of normal instruments and
620     drumkits is possible
621 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
622     MIDI instrument maps, MIDI instruments, FX sends, global volume.
623 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
624     due to a constant size RingBuffer FIFO which is now replaced by a
625     dynamic (unlimited) size std::list FIFO
626 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
627     output channels for being processed by external effect processors
628     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
629     controllers
630 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
631 iliev 1130 - Implemented new, improved notification system
632 schoenebeck 1149 - fixed compilation errors regarding OSX
633     (patch by Toshi Nagata)
634 iliev 1161 - implemented instruments database
635 iliev 1345 - added support for escape sequences to the instruments database
636 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
637     within the sampler's process (by using instrument editor plugins),
638     you'll notice the new "Registered instrument editors:" message on
639 schoenebeck 1407 startup, added a new LSCP command:
640     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
641 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
642     given sampler channel, the plugin path can be overridden at compile
643     time with ./configure --enable-plugin-dir=/some/dir
644 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
645     in the sampler's process to safely edit instruments while playing
646     without a crash (hopefully) by either suspending single regions
647     wherever possible or if unavoidable whole engine(s)
648 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
649     policy and priority on thread level, set a minimum stack size for
650     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
651     threads simply inherited properties of starting thread instead of
652     setting their own policy and priority
653 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
654     main process did not wait for the stack trace process to finish
655     its output
656 persson 1248 - fixed some minor memory leaks
657 schoenebeck 1259 - reenabled assembly features support, at the moment only for
658     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
659 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
660     register, to avoid relocations in the text segment at runtime)
661 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
662 schoenebeck 947
663     * MIDI driver:
664     - dispatch bank select (MSB and LSB) messages
665    
666 schoenebeck 1049 * audio driver:
667     - the ALSA audio output driver parameters now reflect the correct
668     parameter value ranges for the respective selected sound card
669     (patch by Till Wimmer, a bit fixed and extended)
670    
671 persson 951 * Gigasampler format engine:
672     - if a filter is used and EG2 finishes before EG1, let the voice
673     die when EG2 has finished (this fixes a problem with clicks and
674     voice starvation for some gigs)
675 persson 1038 - playback is no longer disabled during instrument loading
676     - all notes playing on a channel that changes its instrument keep
677     playing with the old instrument until they get a note off
678     command
679 persson 1039 - EG fix: a release value of zero could cause noises or crash
680 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
681 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
682     above max sustain level, which means that there is a decay phase
683     even if sustain is 100%
684 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
685     noises or crashes
686 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
687 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
688     supplied to the configure script (fixes #46)
689 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
690     instead of a fix value
691 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
692     127 (solo mode) only kill voices if the respective mode really
693     changed
694 persson 951
695 schoenebeck 1244 * LSCP server:
696     - fixed compile time error for old Bison versions
697     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
698 schoenebeck 1245 - parser now supports extended ASCII character set
699     (up to ASCII code 255, i.e. includes now umlauts and accents)
700     - filename arguments in LSCP commands now allow to use escape
701     sequences, that is directly literal as one of: \', \", \\, \n, \r,
702     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
703     code value like \xf2) (fixes bug #24)
704 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
705     least one of their text-based parameters (i.e. name, description):
706     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
707     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
708     "SET DB_INSTRUMENT_DIRECTORY NAME",
709     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
710     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
711     "FIND DB_INSTRUMENT_DIRECTORIES"
712 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
713     occured, the unexpected character and the actually expected, possible
714     character(s), the latter only if less than 5 possibilities)
715 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
716     settings
717 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
718     of strings were treated as being one string containing commas
719     (fixes #57)

721 iliev 959 * Bug fixes:
722     - fixed crash occurring on certain LSCP scripts (Bug 39)
723 persson 1038 - another thread safety fix for lscp "load engine" and "set
724     channel audio output device"
725 iliev 1283 - fixed a crash which occurs when reassigning the same engine
726     on a sampler channel with connected MIDI device
727 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
728     device connected to a sampler channel to number less then or equal
729     to the index of the port to which the sampler channel is connected.
730 iliev 1296 - The previous bindings were not been disconnected when altering
731     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
732     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
733 iliev 1297 - The active stream/voice count statistic was incorrect.
734 iliev 1298 - notification events were not been sent for some sampler
735     channel changes
736 iliev 1305 - added default min and max values to restrict the number of allowed
737     audio output channels and MIDI input ports
738 iliev 1306 - the connection to the PCM interface is now closed when destroying
739     an audio output device
740 schoenebeck 1332 - files with slash in their path or filename could not be loaded
741 iliev 959
742 schoenebeck 1221 * test cases:
743     - updated and fixed (haven't been touched in a while)
744    
745 schoenebeck 937 Version 0.4.0 (24 November 2006)
746 persson 696
747 schoenebeck 697 * packaging changes:
748 capela 868 - changed deprecated copyright attribute to license; added ldconfig
749     to post-(un)install steps; added devel package for liblinuxsampler;
750     to linuxsampler.spec (RPM)
751 schoenebeck 697 - install necessary development header files for allowing 3rd party
752     applications to link against liblinuxsampler
753     - liblinuxsampler's API documentation can be generated with 'make docs'
754     (Doxygen required)
755 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
756     implementation (currently either an integer math solution or a
757     di-harmonic approximation), automatic detection can be overriden
758     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
759     configure script argument though (mandatory for cross-compilation)
760 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
761     provided some on his own (as CXXFLAGS)
762 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
763     messages
764 schoenebeck 852 - added compile time options to allow disabling the various audio and
765     MIDI drivers
766 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
767     (patch by Ebrahim Mayat)
768 schoenebeck 697
769 persson 696 * Gigasampler format engine:
770 schoenebeck 738 - extensive synthesis optimization
771     (reimplementation of EGs and LFO(s), removed synthesis parameter
772     prerendering and the synthesis parameter matrix in general, splitting
773     each audio fragment into subfragments now where each subfragment uses
774 persson 830 constant pitch and filter coefficients. The volume coefficient is
775     linearly interpolated inside a subfragment, unless
776     --disable-interpolate-volume is set.)
777 persson 696 - fine tuning of the EG modulation parameters
778 persson 729 - improved filter cutoff calculation by adding support for the
779     following gig parameters: Cutoff freq (used when no cutoff
780     controller is defined), Control invert, Minimum cutoff, Velocity
781 persson 791 curve and Velocity range. The keyboard tracking now scales
782     cutoff frequency instead of resonance.
783 persson 877 - added support for gig parameter Resonance.
784 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
785 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
786     which can be overridden with --enable-global-attenuation
787 persson 783 - EG fixes: made the length of "attack hold" stage more
788     accurate. Release stage can now start before attack stage
789 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
790     time now has a minimal value to prevent clicks.
791 persson 799 - fixed pitch changes larger than one octave
792 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
793     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
794     all modes can be altered via standard GM messages, that is CC5 for
795     altering portamento time, CC65 for enabling / disabling portamento
796     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
797 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
798     parameter) and crossfade
799 persson 831 - added support for the "attenuation controller threshold" gig
800     parameter
801 persson 832 - added smoothing of volume changes caused by control change
802     messages
803 persson 865 - sample loop parameters are now taken from the DimensionRegion
804     instead of the wave chunk
805     - fixed keyswitching for v3 gigs with a number of keyswitch splits
806     not equal to a power of two
807 persson 877 - reimplementation of the filter algorithm. The new filter is more
808     accurate and supports all gig filter types, including bandreject
809     and lowpass turbo.
810 persson 903 - real support for 24 bit samples - samples are not truncated to
811     16 bits anymore
812     - support for aftertouch (channel pressure, not polyphonic
813     aftertouch)
814 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
815     amplifying from 0)
816 persson 696
817 schoenebeck 711 * LSCP server:
818     - fixed application exit on broken pipe error (fixes bug #20)
819 iliev 793 - fixed the notification messages delay due to lack of
820     network activity (fixes bug #26)
821 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
822     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
823 schoenebeck 711
824 schoenebeck 838 * audio driver:
825     - added aRts audio output driver (by no means RT safe)
826    
827 schoenebeck 775 * MIDI driver:
828     - fixed legacy sysex code which caused dispatching of MIDI SysEx
829     messages several times instead of once
830 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
831     for events (i.e. for offline rendering based MIDI drivers)
832 persson 922 - added checks for bad MIDI data
833 schoenebeck 775
834 schoenebeck 900 * linuxsampler application:
835     - show available sampler engine types on startup
836    
837 schoenebeck 705 * general changes:
838     - support for muting sampler channels and solo mode of the same, two new
839     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
840     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
841     introduced for this, the behavior is the same like on a mixer console
842 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
843     --enable-process-muted-channels which can be used to enable the
844     processing of muted channels.
845 iliev 777 - support for sostenuto pedal
846 iliev 779 - support for monitoring the total number of active voices
847 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
848     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
849 persson 835 - fixed some memory management errors
850 persson 841 - fixed some concurrency problems that could lead to crashes when
851     LSCP commands were executed
852 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
853     sampler channel (fixes bug #36)
854 schoenebeck 705
855 schoenebeck 692 Version 0.3.3 (15 July 2005)
856 schoenebeck 686
857     * packaging changes:
858     - fixed compilation with gcc 4.0
859    
860 schoenebeck 687 * Gigasampler format engine:
861     - LFO preprocessing was performed even though the respective LFO was
862     disabled by the instrument patch (minor efficiency fix)
863 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
864     for volume ramp downs in the same fragment (needed for current voice
865     stealing implementation) then simply inform the user with a warning
866     about possible click sounds and reduce the volume ramp down
867     appropriately instead of cancelling the audio device connection
868 schoenebeck 687
869 schoenebeck 677 Version 0.3.2 (24 June 2005)
870 schoenebeck 609
871     * packaging changes:
872     - updated autotools build files to compile on OS X
873     (conditional compilation of CoreMIDI and MidiShare drivers)
874 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
875     './configure --disable-asm' (definitely not recommended)
876 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
877     - require automake (>= 1.5) for 'make -f Makefile.cvs'
878     (due to 'dist-bzip2' automake option)
879 schoenebeck 649
880     * Gigasampler format engine:
881     - support for the gig parameters for "release velocity response" curves
882     - fine tuning of the EGADSR envelope
883     - volume of release triggered samples now depends on note-on velocity,
884     note length and gig parameter "release trigger decay" instead of
885     note-off velocity.
886 schoenebeck 663 - revised voice stealing
887     (fixes crash and endless loop caused by voice stealing)
888 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
889 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
890     instead of when the respective voice is actually launched
891     (fixes undefined behavior if stolen voices belonged to a key group -
892     this case was followed by a "killed voice survived" error message)
893 schoenebeck 669 - fixed minor issue with null/silence samples
894     (those stole voices even though they don't need a voice at all which
895     resulted in "voice stealing didn't work out" messages)
896 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
897     instrument or audio output device change
898 schoenebeck 654
899 schoenebeck 620 * LSCP server:
900 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
901 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
902 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
903 schoenebeck 609
904 schoenebeck 668 * linuxsampler application:
905     - added command line parameters --lscp-addr and --lscp-port to override
906     default IP address and port of LSCP server
907    
908 schoenebeck 579 Version 0.3.1 (24 May 2005)
909    
910     * initial release
