* Fixed variable underflow in VirtualMidiDevice, which caused graphical
  virtual keyboards in frontends / instrument editors being stuck.
* VirtualKeyboard: allow to dynamically adjust max. MIDI events.
* RingBuffer: added resize() method

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
23 - fixed linkage error when building with
24 LDFLAGS="-Wl,--no-undefined" (#190)
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", ...
57 - Added new C++ API method Sampler::GetGlobalMaxVoices().
58 - Added new C++ API method Sampler::GetGlobalMaxStreams().
59 - Added new C++ API method Sampler::SetGlobalMaxVoices().
60 - Added new C++ API method Sampler::SetGlobalMaxStreams().

63 applying panning, instead of using two separate pan functions in
64 series (#182)

71 key
72 - bugfix: pitch LFO controller "internal+aftertouch" was broken
73 - bugfix: filter keyboard tracking was broken

75 filter parameters in each sub fragment)
76 - handle special case when pan parameter in gig file has max or
77 min value
79 * SFZ format engine:
80 - Initial implementation (not usable yet)

409 plugin DLL on Windows systems failed
410 - fixed memory leaks that occurred when liblinuxsampler was unloaded
411 - optimized the SynchronizedConfig class so it doesn't wait
412 unnecessarily long after an update

414 events (e.g. to highlight the pressed keys on the virtual keyboard
415 of gigedit)
416 - added support for triggering notes by instrument editors (see above)
417 - be verbose on DLL load errors (on Linux)
418 - fixed di-harmonic triangle LFO implementation (this LFO implementation

422 - experimental support for running LinuxSampler as a DSSI, LV2 and
423 VST plugin
424 - notification events for stream/voice count statistics are now sent
425 only when there are actual changes
426 - added memory ordering constraints to improve stability on
427 multi-core and multi-cpu systems
428 - maximum voices and disk streams can now be altered at runtime
429 - fixed CPU feature detection on x86_64 (maybe fixes #108)
430 - automatic stacktrace mechanism is now turned off by default and can
431 be switched on by command line option "--stacktrace" (the automatic
432 stacktrace mechanism seems to be broken on most systems at the moment)
433 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
434 a pointer to the launched InstrumentEditor object
435 - added optional 3rd party user data parameter for following
436 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
437 InstrumentEditor::Launch(),
438 InstrumentManager::LaunchInstrumentEditor()
439 - theoretical fix: made SynchronizedConfig follow C++0x memory
440 model more strictly
441 - fixes for using large audio device buffers
442 - Windows: add the installation directory to the DLL search path
443 when loading an editor plugin (solves problems with VST and
444 gigedit on systems with other GTK versions installed)
446 * audio driver:
447 - removed the nonsense audio channel constraint (which was hard coded to
448 max. 100 audio channels) for most audio drivers
449 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
450 opposed to the LSCP specs
451 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
452 reflected the wrong value
453 - fixed a memory management bug in ASIO driver
454 - Makefile fix: JACK_CFLAGS wasn't used
455 - JACK: use jack_client_open instead of the deprecated
456 jack_client_new
457 - added (experimental) CoreAudio driver
458 - applied old fixes to the ASIO driver that were included in the
459 previous binary release but accidentally never committed to CVS
460 (fixes #117)
461 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
462 win64)
463 - VST: added support for sample rate and buffer size changes
464 - VST: close editor (Fantasia) when the VST is removed
465 - VST: avoid opening Fantasia more than once for each VST instance
466 - VST: export main function as "main" on Linux too (fix for
467 energyXT)
468 - VST: changed number of output channels from one stereo to 16
469 stereo
470 - added channel routing, fxsends and midi maps to the settings
471 stored in the plugin state
472 - performance optimization of AudioChannel::MixTo() and
473 AudioChannel::CopyTo() methods using GCC vector exensions
474 (if available)
475 - ASIO fixes: avoid initializing the device twice, avoid throwing
476 exception when getting parameters from a disconnected device
478 * MIDI driver:
479 - added JACK MIDI driver
480 - dispatch bank select as ordinary CC as well, the user might seriously
481 want to (mis)use it for some purpose ("fixed" in all current MIDI
482 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
483 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
484 CoreMidi or AU
485 - fixed mingw-w64 compilation error in MME driver
486 - made program change handling in MIDI thread real-time safe by
487 moving the logic to a non-RT thread
488 - fixed minor memory leak in ALSA driver
490 * instruments database:
491 - avoid time consuming samples scanning when adding instruments
492 to the instruments database
493 - added support for handling lost files in the instruments database
494 - Implemented option for adding instruments in separate directories
495 in the instruments database
496 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
497 - work-around for missing fnmatch function on Windows to make
498 instrument database compilable
499 - added instrument database support on Windows
500 works with both standalone mode and VST plugin.
501 the instruments DB file is located in
502 %USERPROFILE%\.linuxsampler\instruments.db which allows different
503 databases for each windows user
504 if no DB is present it automatically creates the .linuxsampler subdir
505 and then creates an empty DB
506 - fixed recursive import, which was broken on Windows
508 * Gigasampler format engine:
509 - fixed a memory leak that could happen when a channel was deleted
510 while notes were playing
511 - made it possible to load an instrument even if the audio thread
512 isn't running
513 - added partial support for the "Controller Triggered" MIDI rule,
514 enough for piano gigs with pedal noise samples
515 - minor fix: only mark FX sends as being modified if really the
516 respective FX send MIDI controller was used
517 - added support for GM global device volume SysEx message
518 (can be selected at compile time to either apply globally to the
519 whole sampler [default] or only to the sampler channels that are
520 connected to the respective MIDI input port the SysEx message arrived
521 on)
522 - bugfix: notes triggered at position 0 in the audio buffer were
523 sometimes wrongly killed in the same buffer, causing no sound to
524 be played
525 - added support for chromatic / drumkit mode Roland GS Sysex message
526 which is usally used to switch a part between chromatic sounds and
527 drumkit sounds (as opposed to their common default setting of MIDI
528 part 10 being a drumkit part and all other ones chromatic parts), in
529 LS however one can switch between the first 16 MIDI instrument maps
530 defined for the sampler
531 - made it possible to create multiple sample channels even if the
532 audio thread isn't running
533 - fixed crash when removing channel with active voices (#116)
534 - bugfix: on sample reference changes (instrument editor), only
535 un-cache the respective sample if it's really not used by any
536 sampler engine anymore
537 - re-cache samples in case they were changed by an instrument editor,
538 e.g. when a sample was added while playing (#82)
539 - fixed hanging notes which occured when note-off event had the exact
540 same time stamp as the voice's note-on event and occured both in the
541 same audio fragment cycle (fixes bug #112)
542 - added support for the "fine tune" and "pitch bend range"
543 instrument-level gig parameters
544 - fixed minor artifacts in pitch bend handling
545 - added support for GS Reset SysEx message
546 - allow gig files to use unlimited downward pitch shifting
547 - added a limit check for upward pitch shifting
548 - bugfix: sometimes, when playing a note twice fast, the second
549 note was silent
550 - fixed crash happening when a pitch bend event arrived at the
551 same time a new instrument was loading
553 * LSCP server:
554 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
555 react on MIDI data arriving on certain sampler channels (so far only
556 Note-On and Note-Off events are sent via this LSCP event)
557 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
558 react on MIDI data arriving on certain MIDI input devices (so far only
559 Note-On and Note-Off events are sent via this LSCP event)
560 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
562 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
563 frontends to send MIDI messages to specific sampler channel
564 - added two additional fields to GET FILE INSTRUMENT INFO command -
566 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
567 was incorrect
568 - Optimized the retrieval of the MIDI instrument mappings
569 - added new LSCP command "SET VOICES" to globally alter the maximum
570 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
571 be triggered respectively
572 - added new LSCP command "SET STREAMS" to globally alter the maximum
573 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
574 which will be triggered respectively
575 - bugfix: retry if "select" returns EINTR (this fixes a crash when
576 a gigedit file dialog is opened)
577 - close all connections when LSCPServer is deleted
578 - hard close of all sockets on exit
579 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
580 driver
582 * Bug fixes:
583 - fixed a crash which occurs when removing a sampler channel waiting
584 to start instrument loading after another channel
585 - fixed a crash which occurs when removing a sampler channel with
586 instrument loading in progress (bug #113)
587 - fixed termination caused by uncaught exception when adding MIDI
588 instrument with PERSISTENT load mode
589 - fixed possible iterator invalidations when resetting the sampler
590 - fixed memory leaks when issuing the following LSCP commands:
595 - fixed possible compilation error when sqlite is not present
596 - fixed orphaned pointers when setting maximum voices limit (bug #118)
597 - fixed crash when changing the audio output device of a sampler
598 channel with loaded instrument and start playing notes
599 - fixed endless loop in Engine::SuspendAll() (bug #120)
600 - fixed a low-level atomic load function that was broken on 64-bit
601 PowerPC, which probably could cause crashes on that platform
602 - fixed a memory management error which could cause a crash when a
603 plugin was unloaded
604 - bugfix: two private structs had the same name, which could cause
605 problems if the linker chose the wrong constructor
606 - fixed low-level ConditionServer usage bug that caused lockups on
607 Windows
610 Version 0.5.1 (6 December 2007)
612 * packaging changes:
613 - added autoconf checks for pthread library
614 - added autoconf check for pthread bug found on certain NPTL-enabled
615 glibc versions (see Gentoo bug report #194076)
616 - added autoconf checks for MS Windows
618 * general changes:
619 - bugfix: the thread used by an editor plugin didn't die when the
620 editor closed
621 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
622 out all the space. operator--() did not apply size_mask after
623 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
624 order to avoid problems with the _NonVolatileReader functions.
625 - bugfix: Stream.h: added a missing divide by BytesPerSample in
626 GetWriteSpace(). Since this function is currently only used in
627 the stream's qsort() compare function, it didn't trigger any
628 bugs.
629 - Resampler.h, Synthesizer.h: cubic interpolation now works in
630 24bit mode too. Faster method to read 24bit words on little
631 endian machines (x86): replaced 3 byte reads + shifts with a 1
632 unaligned 32bit read and shift
633 - experimental support for MS Windows (MIDI input via MME, AUDIO
634 output via ASIO)
635 - made handling of SIGINT signal (Ctrl-C) a bit more robust
636 - support for monitoring the total number of active disk streams
637 (new LSCP commands: GET TOTAL_STREAM_COUNT,
640 * AUDIO driver:
641 - added Windows ASIO low latency audio driver
643 * MIDI driver:
644 - added MME Windows MIDI driver
646 * LSCP server:
647 - added support for Windows style path / filenames, however with
648 forward slash path separators instead of backslash
649 (i.e. "C:/foo/bar.gig")
650 - allow naughty liblscp to send non-string device parameters within
651 apostrophes as well
652 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
653 "LIST FILE INSTRUMENTS <file>" and
654 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
655 about an arbitrary instrument file on the system where the sampler is
656 running on
658 Version 0.5.0 (15 October 2007)
660 * packaging changes:
661 - config.h is not going to be installed along with liblinuxsampler's
662 API header files anymore
663 - only the API relevant header (and source) files will be exported to
664 the Doxygen API documentation (explicitly listed in Doxyfile.in)
665 - added completely new XCode project files for Mac OSX which is now
666 capable to execute our autoconf environment, thus no need anymore
667 to maintain the compile time configuration file (osx/version.h) for
668 OSX manually (patch by Toshi Nagata)
669 - fixed buggy boolean --enable-foo / --disable-foo configure script
670 parameters
671 - global.h now only covers global definitions that are needed for the
672 C++ API header files, all implementation internal global definitions
673 are now in global_private.h
674 - atomic.h is not exposed to the C++ API anymore
675 - no need to include config.h anymore for using LS's API header files
676 - fixed warnings in API doc generation
678 * general changes:
679 - replaced the old, confusing MIDI program change mechanism by a
680 flexible MIDI instrument mapper which allows to map arbitrary
681 (MIDI bank, MIDI program) pairs with arbitrary
682 (engine type, instrument file, file index) triplets which will be
683 loaded on the respective channel when such MIDI program change
684 messages arrive, beside that, each entry allows to define a life-time
685 strategy for the instrument, so the user can define whether the
686 instrument should i.e. be permanently loaded (to be able to switch
687 quickly among sounds) or i.e. loaded just on demand when the
688 respective program change arrives (to safe RAM space), as well as a
689 global volume factor for each entry, so the user can adjust the volume
690 dynamic of his mapped instrument collection without having to modify
691 the instrument files, also one can manage arbitrary amount of such
692 MIDI instrument maps and assign each sampler channel individually
693 a certain map, so that i.e. separation of normal instruments and
694 drumkits is possible
695 - new notification events for tracking changes to audio/MIDI devices,
696 MIDI instrument maps, MIDI instruments, FX sends, global volume.
697 - sampler was limited to load max. 200 instruments in the background
698 due to a constant size RingBuffer FIFO which is now replaced by a
699 dynamic (unlimited) size std::list FIFO
700 - added FX sends, these allow to route audio signals to arbitrary audio
701 output channels for being processed by external effect processors
702 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
703 controllers
704 - global (sampler wide) volume can now be controlled at runtime
705 - Implemented new, improved notification system
706 - fixed compilation errors regarding OSX
707 (patch by Toshi Nagata)
708 - implemented instruments database
709 - added support for escape sequences to the instruments database
710 - added highly experimental support for on-the-fly instrument editing
711 within the sampler's process (by using instrument editor plugins),
712 you'll notice the new "Registered instrument editors:" message on
713 startup, added a new LSCP command:
714 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
715 to spawn a matching instrument editor for the instrument on the
716 given sampler channel, the plugin path can be overridden at compile
717 time with ./configure --enable-plugin-dir=/some/dir
718 - added experimental code for synchronizing instrument editors hosted
719 in the sampler's process to safely edit instruments while playing
720 without a crash (hopefully) by either suspending single regions
721 wherever possible or if unavoidable whole engine(s)
722 - fixed several issues in fundamental "Thread" class: set scheduling
723 policy and priority on thread level, set a minimum stack size for
724 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
725 threads simply inherited properties of starting thread instead of
726 setting their own policy and priority
727 - minor fix in our automatic stack trace mechanism on crashes, the
728 main process did not wait for the stack trace process to finish
729 its output
730 - fixed some minor memory leaks
731 - reenabled assembly features support, at the moment only for
732 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
733 - minor assembly fix in x86 features detection (don't use the PIC
734 register, to avoid relocations in the text segment at runtime)
735 - POSIX callback functions of Thread.h are hidden
737 * MIDI driver:
738 - dispatch bank select (MSB and LSB) messages
740 * audio driver:
741 - the ALSA audio output driver parameters now reflect the correct
742 parameter value ranges for the respective selected sound card
743 (patch by Till Wimmer, a bit fixed and extended)
745 * Gigasampler format engine:
746 - if a filter is used and EG2 finishes before EG1, let the voice
747 die when EG2 has finished (this fixes a problem with clicks and
748 voice starvation for some gigs)
749 - playback is no longer disabled during instrument loading
750 - all notes playing on a channel that changes its instrument keep
751 playing with the old instrument until they get a note off
752 command
753 - EG fix: a release value of zero could cause noises or crash
754 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
755 - EG fine tuning: when attack is zero the EG starts at a level
756 above max sustain level, which means that there is a decay phase
757 even if sustain is 100%
758 - more EG fixes: the level could sometimes go below zero and cause
759 noises or crashes
760 - minor fix of EGDecay (patch by Toshi Nagata)
761 - fixed compiler error when --enable-override-filter-type was
762 supplied to the configure script (fixes #46)
763 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
764 instead of a fix value
765 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
766 127 (solo mode) only kill voices if the respective mode really
767 changed
769 * LSCP server:
770 - fixed compile time error for old Bison versions
771 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
772 - parser now supports extended ASCII character set
773 (up to ASCII code 255, i.e. includes now umlauts and accents)
774 - filename arguments in LSCP commands now allow to use escape
775 sequences, that is directly literal as one of: \', \", \\, \n, \r,
776 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
777 code value like \xf2) (fixes bug #24)
778 - the following LSCP commands now also support escape sequences for at
779 least one of their text-based parameters (i.e. name, description):
786 - returns verbose syntax errors (line and column where syntax error
787 occured, the unexpected character and the actually expected, possible
788 character(s), the latter only if less than 5 possibilities)
789 - made sure that LSCP syntax is not affected by gigedit locale
790 settings
791 - bugfix regarding strings parameter lists: all comma separated lists
792 of strings were treated as being one string containing commas
793 (fixes #57)
795 * Bug fixes:
796 - fixed crash occurring on certain LSCP scripts (Bug 39)
797 - another thread safety fix for lscp "load engine" and "set
798 channel audio output device"
799 - fixed a crash which occurs when reassigning the same engine
800 on a sampler channel with connected MIDI device
801 - fixed a crash which occurs when changing the number of ports of a MIDI
802 device connected to a sampler channel to number less then or equal
803 to the index of the port to which the sampler channel is connected.
804 - The previous bindings were not been disconnected when altering
805 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
806 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
807 - The active stream/voice count statistic was incorrect.
808 - notification events were not been sent for some sampler
809 channel changes
810 - added default min and max values to restrict the number of allowed
811 audio output channels and MIDI input ports
812 - the connection to the PCM interface is now closed when destroying
813 an audio output device
814 - files with slash in their path or filename could not be loaded
816 * test cases:
817 - updated and fixed (haven't been touched in a while)
819 Version 0.4.0 (24 November 2006)
821 * packaging changes:
822 - changed deprecated copyright attribute to license; added ldconfig
823 to post-(un)install steps; added devel package for liblinuxsampler;
824 to linuxsampler.spec (RPM)
825 - install necessary development header files for allowing 3rd party
826 applications to link against liblinuxsampler
827 - liblinuxsampler's API documentation can be generated with 'make docs'
828 (Doxygen required)
829 - added benchmark to automatically detect the best triangle LFO
830 implementation (currently either an integer math solution or a
831 di-harmonic approximation), automatic detection can be overriden
832 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
833 configure script argument though (mandatory for cross-compilation)
834 - do not automatically pick optimized gcc flags if the user already
835 provided some on his own (as CXXFLAGS)
836 - added compile time option to disable processing of All-Notes-Off MIDI
837 messages
838 - added compile time options to allow disabling the various audio and
839 MIDI drivers
840 - fixed automatic GCC CPU switch detection on PPC
841 (patch by Ebrahim Mayat)
843 * Gigasampler format engine:
844 - extensive synthesis optimization
845 (reimplementation of EGs and LFO(s), removed synthesis parameter
846 prerendering and the synthesis parameter matrix in general, splitting
847 each audio fragment into subfragments now where each subfragment uses
848 constant pitch and filter coefficients. The volume coefficient is
849 linearly interpolated inside a subfragment, unless
850 --disable-interpolate-volume is set.)
851 - fine tuning of the EG modulation parameters
852 - improved filter cutoff calculation by adding support for the
853 following gig parameters: Cutoff freq (used when no cutoff
854 controller is defined), Control invert, Minimum cutoff, Velocity
855 curve and Velocity range. The keyboard tracking now scales
856 cutoff frequency instead of resonance.
857 - added support for gig parameter Resonance.
858 - fixed bug in sysex handling (patch by Juan Linietsky)
859 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
860 which can be overridden with --enable-global-attenuation
861 - EG fixes: made the length of "attack hold" stage more
862 accurate. Release stage can now start before attack stage
863 ends. Cancel release didn't work when sustain was zero. Attack
864 time now has a minimal value to prevent clicks.
865 - fixed pitch changes larger than one octave
866 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
867 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
868 all modes can be altered via standard GM messages, that is CC5 for
869 altering portamento time, CC65 for enabling / disabling portamento
870 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
871 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
872 parameter) and crossfade
873 - added support for the "attenuation controller threshold" gig
874 parameter
875 - added smoothing of volume changes caused by control change
876 messages
877 - sample loop parameters are now taken from the DimensionRegion
878 instead of the wave chunk
879 - fixed keyswitching for v3 gigs with a number of keyswitch splits
880 not equal to a power of two
881 - reimplementation of the filter algorithm. The new filter is more
882 accurate and supports all gig filter types, including bandreject
883 and lowpass turbo.
884 - real support for 24 bit samples - samples are not truncated to
885 16 bits anymore
886 - support for aftertouch (channel pressure, not polyphonic
887 aftertouch)
888 - LFO1 behaviour fixed (dampening from max volume instead of
889 amplifying from 0)
891 * LSCP server:
892 - fixed application exit on broken pipe error (fixes bug #20)
893 - fixed the notification messages delay due to lack of
894 network activity (fixes bug #26)
895 - fixed parser bug which occured on space(s) within device parameters
898 * audio driver:
899 - added aRts audio output driver (by no means RT safe)
901 * MIDI driver:
902 - fixed legacy sysex code which caused dispatching of MIDI SysEx
903 messages several times instead of once
904 - API extension for MIDI drivers which already supply exact time stamps
905 for events (i.e. for offline rendering based MIDI drivers)
906 - added checks for bad MIDI data
908 * linuxsampler application:
909 - show available sampler engine types on startup
911 * general changes:
912 - support for muting sampler channels and solo mode of the same, two new
913 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
914 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
915 introduced for this, the behavior is the same like on a mixer console
916 (patch by Grigor Iliev, a bit adjusted). Also added configure option
917 --enable-process-muted-channels which can be used to enable the
918 processing of muted channels.
919 - support for sostenuto pedal
920 - support for monitoring the total number of active voices
923 - fixed some memory management errors
924 - fixed some concurrency problems that could lead to crashes when
925 LSCP commands were executed
926 - fixed crash when instrument loading failed previously on the same
927 sampler channel (fixes bug #36)
929 Version 0.3.3 (15 July 2005)
931 * packaging changes:
932 - fixed compilation with gcc 4.0
934 * Gigasampler format engine:
935 - LFO preprocessing was performed even though the respective LFO was
936 disabled by the instrument patch (minor efficiency fix)
937 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
938 for volume ramp downs in the same fragment (needed for current voice
939 stealing implementation) then simply inform the user with a warning
940 about possible click sounds and reduce the volume ramp down
941 appropriately instead of cancelling the audio device connection
943 Version 0.3.2 (24 June 2005)
945 * packaging changes:
946 - updated autotools build files to compile on OS X
947 (conditional compilation of CoreMIDI and MidiShare drivers)
948 - hand-crafted assembly optimization code can be disabled with
949 './configure --disable-asm' (definitely not recommended)
950 - fixed 'make dist' rule to include all necessary files
951 - require automake (>= 1.5) for 'make -f Makefile.cvs'
952 (due to 'dist-bzip2' automake option)
954 * Gigasampler format engine:
955 - support for the gig parameters for "release velocity response" curves
956 - fine tuning of the EGADSR envelope
957 - volume of release triggered samples now depends on note-on velocity,
958 note length and gig parameter "release trigger decay" instead of
959 note-off velocity.
960 - revised voice stealing
961 (fixes crash and endless loop caused by voice stealing)
962 - don't reset scale tuning on instrument or audio output device change
963 - handle key group conflicts right at the beginning of each fragment
964 instead of when the respective voice is actually launched
965 (fixes undefined behavior if stolen voices belonged to a key group -
966 this case was followed by a "killed voice survived" error message)
967 - fixed minor issue with null/silence samples
968 (those stole voices even though they don't need a voice at all which
969 resulted in "voice stealing didn't work out" messages)
970 - don't reset volume, pan, pitch and MIDI controller values on
971 instrument or audio output device change
973 * LSCP server:
974 - fixed some crashes (patch by Grigor Iliev, fixes #19)
975 - fixed LSCP event "CHANNEL_INFO" notification
976 (e.g. did not notify on volume changes or MIDI program change events)
978 * linuxsampler application:
979 - added command line parameters --lscp-addr and --lscp-port to override
980 default IP address and port of LSCP server
982 Version 0.3.1 (24 May 2005)
984 * initial release
