* VST: implemented retrieval and switching of programs using the
  sampler's internal MIDI instrument mapping system
* VST: reply to "canDo" plugin features we don't know as "don't know"
* bumped version to 1.0.0.svn19

1 Version CVS HEAD (?)
3 * packaging changes:
4 - fixed building with newer MinGW-w64
5 - Mac OS X: support the new dir for Core Audio SDK
6 - Mac OS X: fixed building outside source directory
7 - made sure all source files for hostplugins are included when
8 doing "make dist"
9 - removed empty directories left from the cvs to svn migration
10 - fixed compilation with gcc 4.6.1
11 - another "make dist" fix, for the LV2 plugin
12 - made --enable-pthread-testcancel default on Mac OS X
13 - minor Makefile fix for building lscpparser when build and source
14 directories are separate
15 - Mac OS X: made it possible to specify plugin installation dir to
16 configure
17 - Mac OS X: Makefile fix for the install-strip target
18 - fixed compilation with gcc 4.7
19 - fixed configure script error with old autoconf versions
20 - lsatomic.h: use gcc provided atomic functions if building with
21 gcc 4.7 and C++11
22 - modernized configure script
24 * general changes:
25 - Refactoring: moved the independent code from
26 the Gigasampler format engine to base classes
27 - command line option '--profile' is currently disabled, since the
28 respective profiling code is currently broken
29 - Introduced support for optional environment variable
30 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
31 where the sampler shall look for instrument editor plugins
32 (patch by Luis Garrido, slightly modified).
33 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
34 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
35 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
36 note (in this implementation of the sampler its simply hard routed to
37 the 1st effect send of the sampler channel, no matter what the actual
38 effect type is)
39 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
40 note (in this implementation of the sampler its simply hard routed to
41 the 2nd effect send of the sampler channel, no matter what the actual
42 effect type is)
43 - implemented support for internal LADSPA effects
44 - raised limit of program change queue from 100 to 512
45 (as suggested by Alex Stone)
46 - implemented sine LFO, pulse LFO and saw LFO
47 - experimental support for per voice equalization
48 - added command line option --exec-after-init
49 - Introduced new C++ API method:
50 EngineChannel::InstrumentFileName(int index)
51 allowing to retrieve the whole list of files used for the loaded
52 instrument on an engine channel (a.k.a. part). Some GigaStudio
53 instruments for example are splitted over several files like
54 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
56 * Gigasampler format engine:
57 - implemented the "round robin keyboard" dimension
58 - fixed round robin and random dimensions for cases when number of
59 dimension zones is not a power of two
60 - made round robin use a counter for each region instead of each
61 key
63 * SFZ format engine:

280 - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
281 the driver will automatically connect to other CoreMIDI clients' ports
282 (e.g. external MIDI devices being attached to the Mac)

339 it caused hanging threads on Windows
340 - Fixed possible crashes due to corrupted MIDI/audio device list
341 after MIDI/audio device creation failure
342 - When creating MIDI instrument map entries with "PERSISTENT" type, the
343 instruments were uselessly precached with zero samples, however it still
344 took the full preloading time and on 1st program change the respective
345 instrument was completely reloaded again.

363 playing a note in a key group
365 Version 1.0.0 (31 July 2009)
367 * packaging changes:
368 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

388 - bugfix: on some POSIX systems instrument editor plugins refused to
389 load as we used a non-portable Linux specific struct field
390 (fixes bug #70, patch by Ronald Baljeu)
391 - fixed endless loop which occured when loading an instrument editor
392 plugin DLL on Windows systems failed
393 - fixed memory leaks that occurred when liblinuxsampler was unloaded
394 - optimized the SynchronizedConfig class so it doesn't wait
395 unnecessarily long after an update

397 events (e.g. to highlight the pressed keys on the virtual keyboard
398 of gigedit)
399 - added support for triggering notes by instrument editors (see above)
400 - be verbose on DLL load errors (on Linux)
401 - fixed di-harmonic triangle LFO implementation (this LFO implementation
402 is only used by very few systems, most pick the int math
403 implementation, which is usually faster)
404 - fixes for audio drivers with varying buffer sizes

412 - fixed CPU feature detection on x86_64 (maybe fixes #108)
413 - automatic stacktrace mechanism is now turned off by default and can
414 be switched on by command line option "--stacktrace" (the automatic
415 stacktrace mechanism seems to be broken on most systems at the moment)
416 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
417 a pointer to the launched InstrumentEditor object
418 - added optional 3rd party user data parameter for following
419 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
420 InstrumentEditor::Launch(),
421 InstrumentManager::LaunchInstrumentEditor()
422 - theoretical fix: made SynchronizedConfig follow C++0x memory
423 model more strictly
424 - fixes for using large audio device buffers
425 - Windows: add the installation directory to the DLL search path
426 when loading an editor plugin (solves problems with VST and
427 gigedit on systems with other GTK versions installed)
429 * audio driver:
430 - removed the nonsense audio channel constraint (which was hard coded to
431 max. 100 audio channels) for most audio drivers
432 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
433 opposed to the LSCP specs
434 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
435 reflected the wrong value
436 - fixed a memory management bug in ASIO driver
437 - Makefile fix: JACK_CFLAGS wasn't used
438 - JACK: use jack_client_open instead of the deprecated
439 jack_client_new
440 - added (experimental) CoreAudio driver
441 - applied old fixes to the ASIO driver that were included in the
442 previous binary release but accidentally never committed to CVS
443 (fixes #117)
444 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
445 win64)
446 - VST: added support for sample rate and buffer size changes
447 - VST: close editor (Fantasia) when the VST is removed
448 - VST: avoid opening Fantasia more than once for each VST instance
449 - VST: export main function as "main" on Linux too (fix for
450 energyXT)
451 - VST: changed number of output channels from one stereo to 16
452 stereo
453 - added channel routing, fxsends and midi maps to the settings
454 stored in the plugin state
455 - performance optimization of AudioChannel::MixTo() and
456 AudioChannel::CopyTo() methods using GCC vector exensions
457 (if available)
458 - ASIO fixes: avoid initializing the device twice, avoid throwing
459 exception when getting parameters from a disconnected device
461 * MIDI driver:
462 - added JACK MIDI driver
463 - dispatch bank select as ordinary CC as well, the user might seriously
464 want to (mis)use it for some purpose ("fixed" in all current MIDI
465 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
466 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
467 CoreMidi or AU
468 - fixed mingw-w64 compilation error in MME driver
469 - made program change handling in MIDI thread real-time safe by
470 moving the logic to a non-RT thread
471 - fixed minor memory leak in ALSA driver
473 * instruments database:
474 - avoid time consuming samples scanning when adding instruments
475 to the instruments database
476 - added support for handling lost files in the instruments database
477 - Implemented option for adding instruments in separate directories
478 in the instruments database
479 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
480 - work-around for missing fnmatch function on Windows to make
481 instrument database compilable
482 - added instrument database support on Windows
483 works with both standalone mode and VST plugin.
484 the instruments DB file is located in
485 %USERPROFILE%\.linuxsampler\instruments.db which allows different
486 databases for each windows user
487 if no DB is present it automatically creates the .linuxsampler subdir
488 and then creates an empty DB
489 - fixed recursive import, which was broken on Windows
491 * Gigasampler format engine:
492 - fixed a memory leak that could happen when a channel was deleted
493 while notes were playing
494 - made it possible to load an instrument even if the audio thread
495 isn't running
496 - added partial support for the "Controller Triggered" MIDI rule,
497 enough for piano gigs with pedal noise samples
498 - minor fix: only mark FX sends as being modified if really the
499 respective FX send MIDI controller was used
500 - added support for GM global device volume SysEx message
501 (can be selected at compile time to either apply globally to the
502 whole sampler [default] or only to the sampler channels that are
503 connected to the respective MIDI input port the SysEx message arrived
504 on)
505 - bugfix: notes triggered at position 0 in the audio buffer were
506 sometimes wrongly killed in the same buffer, causing no sound to
507 be played
508 - added support for chromatic / drumkit mode Roland GS Sysex message
509 which is usally used to switch a part between chromatic sounds and
510 drumkit sounds (as opposed to their common default setting of MIDI
511 part 10 being a drumkit part and all other ones chromatic parts), in
512 LS however one can switch between the first 16 MIDI instrument maps
513 defined for the sampler
514 - made it possible to create multiple sample channels even if the
515 audio thread isn't running
516 - fixed crash when removing channel with active voices (#116)
517 - bugfix: on sample reference changes (instrument editor), only
518 un-cache the respective sample if it's really not used by any
519 sampler engine anymore
520 - re-cache samples in case they were changed by an instrument editor,
521 e.g. when a sample was added while playing (#82)
522 - fixed hanging notes which occured when note-off event had the exact
523 same time stamp as the voice's note-on event and occured both in the
524 same audio fragment cycle (fixes bug #112)
525 - added support for the "fine tune" and "pitch bend range"
526 instrument-level gig parameters
527 - fixed minor artifacts in pitch bend handling
528 - added support for GS Reset SysEx message
529 - allow gig files to use unlimited downward pitch shifting
530 - added a limit check for upward pitch shifting
531 - bugfix: sometimes, when playing a note twice fast, the second
532 note was silent
533 - fixed crash happening when a pitch bend event arrived at the
534 same time a new instrument was loading
536 * LSCP server:
537 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
538 react on MIDI data arriving on certain sampler channels (so far only
539 Note-On and Note-Off events are sent via this LSCP event)
540 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
541 react on MIDI data arriving on certain MIDI input devices (so far only
542 Note-On and Note-Off events are sent via this LSCP event)
543 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
545 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
546 frontends to send MIDI messages to specific sampler channel
547 - added two additional fields to GET FILE INSTRUMENT INFO command -
549 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
550 was incorrect
551 - Optimized the retrieval of the MIDI instrument mappings
552 - added new LSCP command "SET VOICES" to globally alter the maximum
553 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
554 be triggered respectively
555 - added new LSCP command "SET STREAMS" to globally alter the maximum
556 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
557 which will be triggered respectively
558 - bugfix: retry if "select" returns EINTR (this fixes a crash when
559 a gigedit file dialog is opened)
560 - close all connections when LSCPServer is deleted
561 - hard close of all sockets on exit
562 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
563 driver
565 * Bug fixes:
566 - fixed a crash which occurs when removing a sampler channel waiting
567 to start instrument loading after another channel
568 - fixed a crash which occurs when removing a sampler channel with
569 instrument loading in progress (bug #113)
570 - fixed termination caused by uncaught exception when adding MIDI
571 instrument with PERSISTENT load mode
572 - fixed possible iterator invalidations when resetting the sampler
573 - fixed memory leaks when issuing the following LSCP commands:
578 - fixed possible compilation error when sqlite is not present
579 - fixed orphaned pointers when setting maximum voices limit (bug #118)
580 - fixed crash when changing the audio output device of a sampler
581 channel with loaded instrument and start playing notes
582 - fixed endless loop in Engine::SuspendAll() (bug #120)
583 - fixed a low-level atomic load function that was broken on 64-bit
584 PowerPC, which probably could cause crashes on that platform
585 - fixed a memory management error which could cause a crash when a
586 plugin was unloaded
587 - bugfix: two private structs had the same name, which could cause
588 problems if the linker chose the wrong constructor
589 - fixed low-level ConditionServer usage bug that caused lockups on
590 Windows
593 Version 0.5.1 (6 December 2007)
595 * packaging changes:
596 - added autoconf checks for pthread library
597 - added autoconf check for pthread bug found on certain NPTL-enabled
598 glibc versions (see Gentoo bug report #194076)
599 - added autoconf checks for MS Windows
601 * general changes:
602 - bugfix: the thread used by an editor plugin didn't die when the
603 editor closed
604 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
605 out all the space. operator--() did not apply size_mask after
606 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
607 order to avoid problems with the _NonVolatileReader functions.
608 - bugfix: Stream.h: added a missing divide by BytesPerSample in
609 GetWriteSpace(). Since this function is currently only used in
610 the stream's qsort() compare function, it didn't trigger any
611 bugs.
612 - Resampler.h, Synthesizer.h: cubic interpolation now works in
613 24bit mode too. Faster method to read 24bit words on little
614 endian machines (x86): replaced 3 byte reads + shifts with a 1
615 unaligned 32bit read and shift
616 - experimental support for MS Windows (MIDI input via MME, AUDIO
617 output via ASIO)
618 - made handling of SIGINT signal (Ctrl-C) a bit more robust
619 - support for monitoring the total number of active disk streams
620 (new LSCP commands: GET TOTAL_STREAM_COUNT,
623 * AUDIO driver:
624 - added Windows ASIO low latency audio driver
626 * MIDI driver:
627 - added MME Windows MIDI driver
629 * LSCP server:
630 - added support for Windows style path / filenames, however with
631 forward slash path separators instead of backslash
632 (i.e. "C:/foo/bar.gig")
633 - allow naughty liblscp to send non-string device parameters within
634 apostrophes as well
635 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
636 "LIST FILE INSTRUMENTS <file>" and
637 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
638 about an arbitrary instrument file on the system where the sampler is
639 running on
641 Version 0.5.0 (15 October 2007)
643 * packaging changes:
644 - config.h is not going to be installed along with liblinuxsampler's
645 API header files anymore
646 - only the API relevant header (and source) files will be exported to
647 the Doxygen API documentation (explicitly listed in Doxyfile.in)
648 - added completely new XCode project files for Mac OSX which is now
649 capable to execute our autoconf environment, thus no need anymore
650 to maintain the compile time configuration file (osx/version.h) for
651 OSX manually (patch by Toshi Nagata)
652 - fixed buggy boolean --enable-foo / --disable-foo configure script
653 parameters
654 - global.h now only covers global definitions that are needed for the
655 C++ API header files, all implementation internal global definitions
656 are now in global_private.h
657 - atomic.h is not exposed to the C++ API anymore
658 - no need to include config.h anymore for using LS's API header files
659 - fixed warnings in API doc generation
661 * general changes:
662 - replaced the old, confusing MIDI program change mechanism by a
663 flexible MIDI instrument mapper which allows to map arbitrary
664 (MIDI bank, MIDI program) pairs with arbitrary
665 (engine type, instrument file, file index) triplets which will be
666 loaded on the respective channel when such MIDI program change
667 messages arrive, beside that, each entry allows to define a life-time
668 strategy for the instrument, so the user can define whether the
669 instrument should i.e. be permanently loaded (to be able to switch
670 quickly among sounds) or i.e. loaded just on demand when the
671 respective program change arrives (to safe RAM space), as well as a
672 global volume factor for each entry, so the user can adjust the volume
673 dynamic of his mapped instrument collection without having to modify
674 the instrument files, also one can manage arbitrary amount of such
675 MIDI instrument maps and assign each sampler channel individually
676 a certain map, so that i.e. separation of normal instruments and
677 drumkits is possible
678 - new notification events for tracking changes to audio/MIDI devices,
679 MIDI instrument maps, MIDI instruments, FX sends, global volume.
680 - sampler was limited to load max. 200 instruments in the background
681 due to a constant size RingBuffer FIFO which is now replaced by a
682 dynamic (unlimited) size std::list FIFO
683 - added FX sends, these allow to route audio signals to arbitrary audio
684 output channels for being processed by external effect processors
685 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
686 controllers
687 - global (sampler wide) volume can now be controlled at runtime
688 - Implemented new, improved notification system
689 - fixed compilation errors regarding OSX
690 (patch by Toshi Nagata)
691 - implemented instruments database
692 - added support for escape sequences to the instruments database
693 - added highly experimental support for on-the-fly instrument editing
694 within the sampler's process (by using instrument editor plugins),
695 you'll notice the new "Registered instrument editors:" message on
696 startup, added a new LSCP command:
697 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
698 to spawn a matching instrument editor for the instrument on the
699 given sampler channel, the plugin path can be overridden at compile
700 time with ./configure --enable-plugin-dir=/some/dir
701 - added experimental code for synchronizing instrument editors hosted
702 in the sampler's process to safely edit instruments while playing
703 without a crash (hopefully) by either suspending single regions
704 wherever possible or if unavoidable whole engine(s)
705 - fixed several issues in fundamental "Thread" class: set scheduling
706 policy and priority on thread level, set a minimum stack size for
707 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
708 threads simply inherited properties of starting thread instead of
709 setting their own policy and priority
710 - minor fix in our automatic stack trace mechanism on crashes, the
711 main process did not wait for the stack trace process to finish
712 its output
713 - fixed some minor memory leaks
714 - reenabled assembly features support, at the moment only for
715 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
716 - minor assembly fix in x86 features detection (don't use the PIC
717 register, to avoid relocations in the text segment at runtime)
718 - POSIX callback functions of Thread.h are hidden
720 * MIDI driver:
721 - dispatch bank select (MSB and LSB) messages
723 * audio driver:
724 - the ALSA audio output driver parameters now reflect the correct
725 parameter value ranges for the respective selected sound card
726 (patch by Till Wimmer, a bit fixed and extended)
728 * Gigasampler format engine:
729 - if a filter is used and EG2 finishes before EG1, let the voice
730 die when EG2 has finished (this fixes a problem with clicks and
731 voice starvation for some gigs)
732 - playback is no longer disabled during instrument loading
733 - all notes playing on a channel that changes its instrument keep
734 playing with the old instrument until they get a note off
735 command
736 - EG fix: a release value of zero could cause noises or crash
737 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
738 - EG fine tuning: when attack is zero the EG starts at a level
739 above max sustain level, which means that there is a decay phase
740 even if sustain is 100%
741 - more EG fixes: the level could sometimes go below zero and cause
742 noises or crashes
743 - minor fix of EGDecay (patch by Toshi Nagata)
744 - fixed compiler error when --enable-override-filter-type was
745 supplied to the configure script (fixes #46)
746 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
747 instead of a fix value
748 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
749 127 (solo mode) only kill voices if the respective mode really
750 changed
752 * LSCP server:
753 - fixed compile time error for old Bison versions
754 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
755 - parser now supports extended ASCII character set
756 (up to ASCII code 255, i.e. includes now umlauts and accents)
757 - filename arguments in LSCP commands now allow to use escape
758 sequences, that is directly literal as one of: \', \", \\, \n, \r,
759 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
760 code value like \xf2) (fixes bug #24)
761 - the following LSCP commands now also support escape sequences for at
762 least one of their text-based parameters (i.e. name, description):
769 - returns verbose syntax errors (line and column where syntax error
770 occured, the unexpected character and the actually expected, possible
771 character(s), the latter only if less than 5 possibilities)
772 - made sure that LSCP syntax is not affected by gigedit locale
773 settings
774 - bugfix regarding strings parameter lists: all comma separated lists
775 of strings were treated as being one string containing commas
776 (fixes #57)
778 * Bug fixes:
779 - fixed crash occurring on certain LSCP scripts (Bug 39)
780 - another thread safety fix for lscp "load engine" and "set
781 channel audio output device"
782 - fixed a crash which occurs when reassigning the same engine
783 on a sampler channel with connected MIDI device
784 - fixed a crash which occurs when changing the number of ports of a MIDI
785 device connected to a sampler channel to number less then or equal
786 to the index of the port to which the sampler channel is connected.
787 - The previous bindings were not been disconnected when altering
788 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
789 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
790 - The active stream/voice count statistic was incorrect.
791 - notification events were not been sent for some sampler
792 channel changes
793 - added default min and max values to restrict the number of allowed
794 audio output channels and MIDI input ports
795 - the connection to the PCM interface is now closed when destroying
796 an audio output device
797 - files with slash in their path or filename could not be loaded
799 * test cases:
800 - updated and fixed (haven't been touched in a while)
802 Version 0.4.0 (24 November 2006)
804 * packaging changes:
805 - changed deprecated copyright attribute to license; added ldconfig
806 to post-(un)install steps; added devel package for liblinuxsampler;
807 to linuxsampler.spec (RPM)
808 - install necessary development header files for allowing 3rd party
809 applications to link against liblinuxsampler
810 - liblinuxsampler's API documentation can be generated with 'make docs'
811 (Doxygen required)
812 - added benchmark to automatically detect the best triangle LFO
813 implementation (currently either an integer math solution or a
814 di-harmonic approximation), automatic detection can be overriden
815 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
816 configure script argument though (mandatory for cross-compilation)
817 - do not automatically pick optimized gcc flags if the user already
818 provided some on his own (as CXXFLAGS)
819 - added compile time option to disable processing of All-Notes-Off MIDI
820 messages
821 - added compile time options to allow disabling the various audio and
822 MIDI drivers
823 - fixed automatic GCC CPU switch detection on PPC
824 (patch by Ebrahim Mayat)
826 * Gigasampler format engine:
827 - extensive synthesis optimization
828 (reimplementation of EGs and LFO(s), removed synthesis parameter
829 prerendering and the synthesis parameter matrix in general, splitting
830 each audio fragment into subfragments now where each subfragment uses
831 constant pitch and filter coefficients. The volume coefficient is
832 linearly interpolated inside a subfragment, unless
833 --disable-interpolate-volume is set.)
834 - fine tuning of the EG modulation parameters
835 - improved filter cutoff calculation by adding support for the
836 following gig parameters: Cutoff freq (used when no cutoff
837 controller is defined), Control invert, Minimum cutoff, Velocity
838 curve and Velocity range. The keyboard tracking now scales
839 cutoff frequency instead of resonance.
840 - added support for gig parameter Resonance.
841 - fixed bug in sysex handling (patch by Juan Linietsky)
842 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
843 which can be overridden with --enable-global-attenuation
844 - EG fixes: made the length of "attack hold" stage more
845 accurate. Release stage can now start before attack stage
846 ends. Cancel release didn't work when sustain was zero. Attack
847 time now has a minimal value to prevent clicks.
848 - fixed pitch changes larger than one octave
849 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
850 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
851 all modes can be altered via standard GM messages, that is CC5 for
852 altering portamento time, CC65 for enabling / disabling portamento
853 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
854 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
855 parameter) and crossfade
856 - added support for the "attenuation controller threshold" gig
857 parameter
858 - added smoothing of volume changes caused by control change
859 messages
860 - sample loop parameters are now taken from the DimensionRegion
861 instead of the wave chunk
862 - fixed keyswitching for v3 gigs with a number of keyswitch splits
863 not equal to a power of two
864 - reimplementation of the filter algorithm. The new filter is more
865 accurate and supports all gig filter types, including bandreject
866 and lowpass turbo.
867 - real support for 24 bit samples - samples are not truncated to
868 16 bits anymore
869 - support for aftertouch (channel pressure, not polyphonic
870 aftertouch)
871 - LFO1 behaviour fixed (dampening from max volume instead of
872 amplifying from 0)
874 * LSCP server:
875 - fixed application exit on broken pipe error (fixes bug #20)
876 - fixed the notification messages delay due to lack of
877 network activity (fixes bug #26)
878 - fixed parser bug which occured on space(s) within device parameters
881 * audio driver:
882 - added aRts audio output driver (by no means RT safe)
884 * MIDI driver:
885 - fixed legacy sysex code which caused dispatching of MIDI SysEx
886 messages several times instead of once
887 - API extension for MIDI drivers which already supply exact time stamps
888 for events (i.e. for offline rendering based MIDI drivers)
889 - added checks for bad MIDI data
891 * linuxsampler application:
892 - show available sampler engine types on startup
894 * general changes:
895 - support for muting sampler channels and solo mode of the same, two new
896 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
897 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
898 introduced for this, the behavior is the same like on a mixer console
899 (patch by Grigor Iliev, a bit adjusted). Also added configure option
900 --enable-process-muted-channels which can be used to enable the
901 processing of muted channels.
902 - support for sostenuto pedal
903 - support for monitoring the total number of active voices
906 - fixed some memory management errors
907 - fixed some concurrency problems that could lead to crashes when
908 LSCP commands were executed
909 - fixed crash when instrument loading failed previously on the same
910 sampler channel (fixes bug #36)
912 Version 0.3.3 (15 July 2005)
914 * packaging changes:
915 - fixed compilation with gcc 4.0
917 * Gigasampler format engine:
918 - LFO preprocessing was performed even though the respective LFO was
919 disabled by the instrument patch (minor efficiency fix)
920 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
921 for volume ramp downs in the same fragment (needed for current voice
922 stealing implementation) then simply inform the user with a warning
923 about possible click sounds and reduce the volume ramp down
924 appropriately instead of cancelling the audio device connection
926 Version 0.3.2 (24 June 2005)
928 * packaging changes:
929 - updated autotools build files to compile on OS X
930 (conditional compilation of CoreMIDI and MidiShare drivers)
931 - hand-crafted assembly optimization code can be disabled with
932 './configure --disable-asm' (definitely not recommended)
933 - fixed 'make dist' rule to include all necessary files
934 - require automake (>= 1.5) for 'make -f Makefile.cvs'
935 (due to 'dist-bzip2' automake option)
937 * Gigasampler format engine:
938 - support for the gig parameters for "release velocity response" curves
939 - fine tuning of the EGADSR envelope
940 - volume of release triggered samples now depends on note-on velocity,
941 note length and gig parameter "release trigger decay" instead of
942 note-off velocity.
943 - revised voice stealing
944 (fixes crash and endless loop caused by voice stealing)
945 - don't reset scale tuning on instrument or audio output device change
946 - handle key group conflicts right at the beginning of each fragment
947 instead of when the respective voice is actually launched
948 (fixes undefined behavior if stolen voices belonged to a key group -
949 this case was followed by a "killed voice survived" error message)
950 - fixed minor issue with null/silence samples
951 (those stole voices even though they don't need a voice at all which
952 resulted in "voice stealing didn't work out" messages)
953 - don't reset volume, pan, pitch and MIDI controller values on
954 instrument or audio output device change
956 * LSCP server:
957 - fixed some crashes (patch by Grigor Iliev, fixes #19)
