* VST: try to open Fantasia automatically on Linux and Mac too (on
  Linux, the Fantasia jar should be placed in <prefix>/share/java)
* VST: fixed crashes on Linux Ardour and EnergyXT

1 Version CVS HEAD (?)
3 * plugin changes:
4 - LV2 "state" extension support (patch by David Robillard)
6 * packaging changes:
7 - fixed building with newer MinGW-w64
8 - 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 - fixed compilation with gcc 4.6.1
14 - another "make dist" fix, for the LV2 plugin
15 - made --enable-pthread-testcancel default on Mac OS X
16 - minor Makefile fix for building lscpparser when build and source
17 directories are separate
18 - Mac OS X: made it possible to specify plugin installation dir to
19 configure
20 - Mac OS X: Makefile fix for the install-strip target
21 - fixed compilation with gcc 4.7
22 - fixed configure script error with old autoconf versions
23 - lsatomic.h: use gcc provided atomic functions if building with
24 gcc 4.7 and C++11
26 * general changes:
27 - Refactoring: moved the independent code from
28 the Gigasampler format engine to base classes
29 - command line option '--profile' is currently disabled, since the
30 respective profiling code is currently broken
31 - 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 - 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 - implemented support for internal LADSPA effects
46 - raised limit of program change queue from 100 to 512
47 (as suggested by Alex Stone)
48 - implemented sine LFO, pulse LFO and saw LFO
49 - experimental support for per voice equalization
50 - added command line option --exec-after-init
51 - 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", ...

59 - implemented the "round robin keyboard" dimension
60 - fixed round robin and random dimensions for cases when number of

317 refresh) could cause instruments to be unloaded
318 - Mac OS X: fixed name collision of enum in EffectControl and
319 wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
320 - Mac OS X: fixed hanging threads

324 after MIDI/audio device creation failure
325 - When creating MIDI instrument map entries with "PERSISTENT" type, the
326 instruments were uselessly precached with zero samples, however it still
327 took the full preloading time and on 1st program change the respective
328 instrument was completely reloaded again.

330 sent to the same sampler channel (patch from the Open Octave
331 project, slightly adjusted)

357 - Windows: look for editor plugins and Fantasia using base
358 directory of liblinuxsampler dll (look in the same directory and one
359 directory above)
360 - configure script fix: removed unconditional use of SSE
361 - fixed building with sqlite installed in a non-standard directory
362 - when cross-compiling, don't try to create instruments.db
363 - fix for new mingw-w64 version, which has usleep
365 * general changes:
366 - bugfix: on some POSIX systems instrument editor plugins refused to

368 (fixes bug #70, patch by Ronald Baljeu)
369 - fixed endless loop which occured when loading an instrument editor
370 plugin DLL on Windows systems failed
371 - fixed memory leaks that occurred when liblinuxsampler was unloaded
372 - optimized the SynchronizedConfig class so it doesn't wait

376 of gigedit)
377 - added support for triggering notes by instrument editors (see above)
378 - be verbose on DLL load errors (on Linux)
379 - fixed di-harmonic triangle LFO implementation (this LFO implementation

381 implementation, which is usually faster)
382 - fixes for audio drivers with varying buffer sizes
383 - experimental support for running LinuxSampler as a DSSI, LV2 and
384 VST plugin
385 - notification events for stream/voice count statistics are now sent

390 - fixed CPU feature detection on x86_64 (maybe fixes #108)
391 - automatic stacktrace mechanism is now turned off by default and can
392 be switched on by command line option "--stacktrace" (the automatic
393 stacktrace mechanism seems to be broken on most systems at the moment)
394 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
395 a pointer to the launched InstrumentEditor object
396 - added optional 3rd party user data parameter for following
397 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
398 InstrumentEditor::Launch(),
399 InstrumentManager::LaunchInstrumentEditor()
400 - theoretical fix: made SynchronizedConfig follow C++0x memory
401 model more strictly
402 - fixes for using large audio device buffers
403 - Windows: add the installation directory to the DLL search path
404 when loading an editor plugin (solves problems with VST and
405 gigedit on systems with other GTK versions installed)
407 * audio driver:
408 - removed the nonsense audio channel constraint (which was hard coded to
409 max. 100 audio channels) for most audio drivers
410 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
411 opposed to the LSCP specs

413 reflected the wrong value
414 - fixed a memory management bug in ASIO driver
415 - Makefile fix: JACK_CFLAGS wasn't used
416 - JACK: use jack_client_open instead of the deprecated
417 jack_client_new

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