27
28 * general changes:
29 - Refactoring: moved the independent code from
30 the Gigasampler format engine to base classes
31 - command line option '--profile' is currently disabled, since the
32 respective profiling code is currently broken
33 - Introduced support for optional environment variable
34 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
35 where the sampler shall look for instrument editor plugins
36 (patch by Luis Garrido, slightly modified).
37 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
38 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
39 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
40 note (in this implementation of the sampler its simply hard routed to
41 the 1st effect send of the sampler channel, no matter what the actual
42 effect type is)
43 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
44 note (in this implementation of the sampler its simply hard routed to
45 the 2nd effect send of the sampler channel, no matter what the actual
46 effect type is)
47 - implemented support for internal LADSPA effects
48 - raised limit of program change queue from 100 to 512
49 (as suggested by Alex Stone)
50 - implemented sine LFO, pulse LFO and saw LFO
51 - experimental support for per voice equalization
52 - added command line option --exec-after-init
53 - Introduced new C++ API method:
54 EngineChannel::InstrumentFileName(int index)
55 allowing to retrieve the whole list of files used for the loaded
56 instrument on an engine channel (a.k.a. part). Some GigaStudio
57 instruments for example are splitted over several files like
58 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
59 - Added new C++ API method Sampler::GetGlobalMaxVoices().
60 - Added new C++ API method Sampler::GetGlobalMaxStreams().
61 - Added new C++ API method Sampler::SetGlobalMaxVoices().
62 - Added new C++ API method Sampler::SetGlobalMaxStreams().
63 - Various "const" and "restrict" optimizations.
64 - all engines: add pan CC value to instrument pan parameter before
65 applying panning, instead of using two separate pan functions in
66 series (#182)
67
68 * Gigasampler format engine:
69 - implemented the "round robin keyboard" dimension

73 key
74 - bugfix: pitch LFO controller "internal+aftertouch" was broken
75 - bugfix: filter keyboard tracking was broken
76 - filter performance fix (an unnecessary copy was made of the
77 filter parameters in each sub fragment)
78 - handle special case when pan parameter in gig file has max or
79 min value
80 - Exclusive Groups: don't ever stop voices of the same note,
81 doesn't sound naturally with a drumkit
82 - fixed EG1 modulation when attack or release is zero
83
84 * SFZ format engine:

397
398 Version 1.0.0 (31 July 2009)
399
400 * packaging changes:

416 - fixed building with sqlite installed in a non-standard directory
417 - when cross-compiling, don't try to create instruments.db
418 - fix for new mingw-w64 version, which has usleep
419
420 * general changes:
421 - bugfix: on some POSIX systems instrument editor plugins refused to
422 load as we used a non-portable Linux specific struct field
423 (fixes bug #70, patch by Ronald Baljeu)
424 - fixed endless loop which occured when loading an instrument editor
425 plugin DLL on Windows systems failed
426 - fixed memory leaks that occurred when liblinuxsampler was unloaded
427 - optimized the SynchronizedConfig class so it doesn't wait
428 unnecessarily long after an update
429 - added support for notifying instrument editors on note-on / note-off
430 events (e.g. to highlight the pressed keys on the virtual keyboard
431 of gigedit)
432 - added support for triggering notes by instrument editors (see above)
433 - be verbose on DLL load errors (on Linux)
434 - fixed di-harmonic triangle LFO implementation (this LFO implementation
435 is only used by very few systems, most pick the int math
436 implementation, which is usually faster)
437 - fixes for audio drivers with varying buffer sizes
438 - experimental support for running LinuxSampler as a DSSI, LV2 and
439 VST plugin
440 - notification events for stream/voice count statistics are now sent
441 only when there are actual changes
442 - added memory ordering constraints to improve stability on
443 multi-core and multi-cpu systems
444 - maximum voices and disk streams can now be altered at runtime
445 - fixed CPU feature detection on x86_64 (maybe fixes #108)
446 - automatic stacktrace mechanism is now turned off by default and can
447 be switched on by command line option "--stacktrace" (the automatic
448 stacktrace mechanism seems to be broken on most systems at the moment)
449 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
450 a pointer to the launched InstrumentEditor object
451 - added optional 3rd party user data parameter for following
452 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
453 InstrumentEditor::Launch(),
454 InstrumentManager::LaunchInstrumentEditor()
455 - theoretical fix: made SynchronizedConfig follow C++0x memory
456 model more strictly
457 - fixes for using large audio device buffers
458 - Windows: add the installation directory to the DLL search path
459 when loading an editor plugin (solves problems with VST and
460 gigedit on systems with other GTK versions installed)
461
462 * audio driver:
463 - removed the nonsense audio channel constraint (which was hard coded to
464 max. 100 audio channels) for most audio drivers
465 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
466 opposed to the LSCP specs
467 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
468 reflected the wrong value
469 - fixed a memory management bug in ASIO driver
470 - Makefile fix: JACK_CFLAGS wasn't used
471 - JACK: use jack_client_open instead of the deprecated
472 jack_client_new
473 - added (experimental) CoreAudio driver
474 - applied old fixes to the ASIO driver that were included in the
475 previous binary release but accidentally never committed to CVS
476 (fixes #117)
477 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
478 win64)
479 - VST: added support for sample rate and buffer size changes
480 - VST: close editor (Fantasia) when the VST is removed
481 - VST: avoid opening Fantasia more than once for each VST instance
482 - VST: export main function as "main" on Linux too (fix for
483 energyXT)
484 - VST: changed number of output channels from one stereo to 16
485 stereo
486 - added channel routing, fxsends and midi maps to the settings
487 stored in the plugin state
488 - performance optimization of AudioChannel::MixTo() and
489 AudioChannel::CopyTo() methods using GCC vector exensions
490 (if available)
491 - ASIO fixes: avoid initializing the device twice, avoid throwing
492 exception when getting parameters from a disconnected device
493
494 * MIDI driver:
495 - added JACK MIDI driver
496 - dispatch bank select as ordinary CC as well, the user might seriously
497 want to (mis)use it for some purpose ("fixed" in all current MIDI
498 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
499 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
500 CoreMidi or AU
501 - fixed mingw-w64 compilation error in MME driver
502 - made program change handling in MIDI thread real-time safe by
503 moving the logic to a non-RT thread
504 - fixed minor memory leak in ALSA driver
505
506 * instruments database:
507 - avoid time consuming samples scanning when adding instruments
508 to the instruments database
509 - added support for handling lost files in the instruments database
510 - Implemented option for adding instruments in separate directories
511 in the instruments database
512 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
513 - work-around for missing fnmatch function on Windows to make
514 instrument database compilable
515 - added instrument database support on Windows
516 works with both standalone mode and VST plugin.
517 the instruments DB file is located in
518 %USERPROFILE%\.linuxsampler\instruments.db which allows different
519 databases for each windows user
520 if no DB is present it automatically creates the .linuxsampler subdir
521 and then creates an empty DB
522 - fixed recursive import, which was broken on Windows
523
524 * Gigasampler format engine:
525 - fixed a memory leak that could happen when a channel was deleted
526 while notes were playing
527 - made it possible to load an instrument even if the audio thread
528 isn't running
529 - added partial support for the "Controller Triggered" MIDI rule,
530 enough for piano gigs with pedal noise samples
531 - minor fix: only mark FX sends as being modified if really the
532 respective FX send MIDI controller was used
533 - added support for GM global device volume SysEx message
534 (can be selected at compile time to either apply globally to the
535 whole sampler [default] or only to the sampler channels that are
536 connected to the respective MIDI input port the SysEx message arrived
537 on)
538 - bugfix: notes triggered at position 0 in the audio buffer were
539 sometimes wrongly killed in the same buffer, causing no sound to
540 be played
541 - added support for chromatic / drumkit mode Roland GS Sysex message
542 which is usally used to switch a part between chromatic sounds and
543 drumkit sounds (as opposed to their common default setting of MIDI
544 part 10 being a drumkit part and all other ones chromatic parts), in
545 LS however one can switch between the first 16 MIDI instrument maps
546 defined for the sampler
547 - made it possible to create multiple sample channels even if the
548 audio thread isn't running
549 - fixed crash when removing channel with active voices (#116)
550 - bugfix: on sample reference changes (instrument editor), only
551 un-cache the respective sample if it's really not used by any
552 sampler engine anymore
553 - re-cache samples in case they were changed by an instrument editor,
554 e.g. when a sample was added while playing (#82)
555 - fixed hanging notes which occured when note-off event had the exact
556 same time stamp as the voice's note-on event and occured both in the
557 same audio fragment cycle (fixes bug #112)
558 - added support for the "fine tune" and "pitch bend range"
559 instrument-level gig parameters
560 - fixed minor artifacts in pitch bend handling
561 - added support for GS Reset SysEx message
562 - allow gig files to use unlimited downward pitch shifting
563 - added a limit check for upward pitch shifting
564 - bugfix: sometimes, when playing a note twice fast, the second
565 note was silent
566 - fixed crash happening when a pitch bend event arrived at the
567 same time a new instrument was loading
568
569 * LSCP server:
570 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
571 react on MIDI data arriving on certain sampler channels (so far only
572 Note-On and Note-Off events are sent via this LSCP event)
573 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
574 react on MIDI data arriving on certain MIDI input devices (so far only
575 Note-On and Note-Off events are sent via this LSCP event)
576 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
577 SET DB_INSTRUMENT FILE_PATH
578 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
579 frontends to send MIDI messages to specific sampler channel
580 - added two additional fields to GET FILE INSTRUMENT INFO command -
581 KEY_BINDINGS and KEYSWITCH_BINDINGS
582 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
583 was incorrect
584 - Optimized the retrieval of the MIDI instrument mappings
585 - added new LSCP command "SET VOICES" to globally alter the maximum
586 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
587 be triggered respectively
588 - added new LSCP command "SET STREAMS" to globally alter the maximum
589 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
590 which will be triggered respectively
591 - bugfix: retry if "select" returns EINTR (this fixes a crash when
592 a gigedit file dialog is opened)
593 - close all connections when LSCPServer is deleted
594 - hard close of all sockets on exit
595 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
596 driver
597
598 * Bug fixes:
599 - fixed a crash which occurs when removing a sampler channel waiting
600 to start instrument loading after another channel
601 - fixed a crash which occurs when removing a sampler channel with
602 instrument loading in progress (bug #113)
603 - fixed termination caused by uncaught exception when adding MIDI
604 instrument with PERSISTENT load mode
605 - fixed possible iterator invalidations when resetting the sampler
606 - fixed memory leaks when issuing the following LSCP commands:
607 GET AUDIO_OUTPUT_DRIVER INFO
608 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
609 GET MIDI_INPUT_DRIVER INFO
610 GET MIDI_INPUT_DRIVER_PARAMETER INFO
611 - fixed possible compilation error when sqlite is not present
612 - fixed orphaned pointers when setting maximum voices limit (bug #118)
613 - fixed crash when changing the audio output device of a sampler
614 channel with loaded instrument and start playing notes
615 - fixed endless loop in Engine::SuspendAll() (bug #120)
616 - fixed a low-level atomic load function that was broken on 64-bit
617 PowerPC, which probably could cause crashes on that platform
618 - fixed a memory management error which could cause a crash when a
619 plugin was unloaded
620 - bugfix: two private structs had the same name, which could cause
621 problems if the linker chose the wrong constructor
622 - fixed low-level ConditionServer usage bug that caused lockups on
623 Windows
624
625
626 Version 0.5.1 (6 December 2007)
627
628 * packaging changes:
629 - added autoconf checks for pthread library
630 - added autoconf check for pthread bug found on certain NPTL-enabled
631 glibc versions (see Gentoo bug report #194076)
632 - added autoconf checks for MS Windows
633
634 * general changes:
635 - bugfix: the thread used by an editor plugin didn't die when the
636 editor closed
637 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
638 out all the space. operator--() did not apply size_mask after
639 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
640 order to avoid problems with the _NonVolatileReader functions.
641 - bugfix: Stream.h: added a missing divide by BytesPerSample in
642 GetWriteSpace(). Since this function is currently only used in
643 the stream's qsort() compare function, it didn't trigger any
644 bugs.
645 - Resampler.h, Synthesizer.h: cubic interpolation now works in
646 24bit mode too. Faster method to read 24bit words on little
647 endian machines (x86): replaced 3 byte reads + shifts with a 1
648 unaligned 32bit read and shift
649 - experimental support for MS Windows (MIDI input via MME, AUDIO
650 output via ASIO)
651 - made handling of SIGINT signal (Ctrl-C) a bit more robust
652 - support for monitoring the total number of active disk streams
653 (new LSCP commands: GET TOTAL_STREAM_COUNT,
654 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
655
656 * AUDIO driver:
657 - added Windows ASIO low latency audio driver
658
659 * MIDI driver:
660 - added MME Windows MIDI driver
661
662 * LSCP server:
663 - added support for Windows style path / filenames, however with
664 forward slash path separators instead of backslash
665 (i.e. "C:/foo/bar.gig")
666 - allow naughty liblscp to send non-string device parameters within
667 apostrophes as well
668 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
669 "LIST FILE INSTRUMENTS <file>" and
670 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
671 about an arbitrary instrument file on the system where the sampler is
672 running on
673
674 Version 0.5.0 (15 October 2007)
675
676 * packaging changes:
677 - config.h is not going to be installed along with liblinuxsampler's
678 API header files anymore
679 - only the API relevant header (and source) files will be exported to
680 the Doxygen API documentation (explicitly listed in Doxyfile.in)
681 - added completely new XCode project files for Mac OSX which is now
682 capable to execute our autoconf environment, thus no need anymore
683 to maintain the compile time configuration file (osx/version.h) for
684 OSX manually (patch by Toshi Nagata)
685 - fixed buggy boolean --enable-foo / --disable-foo configure script
686 parameters
687 - global.h now only covers global definitions that are needed for the
688 C++ API header files, all implementation internal global definitions
689 are now in global_private.h
690 - atomic.h is not exposed to the C++ API anymore
691 - no need to include config.h anymore for using LS's API header files
692 - fixed warnings in API doc generation
693
694 * general changes:
695 - replaced the old, confusing MIDI program change mechanism by a
696 flexible MIDI instrument mapper which allows to map arbitrary
697 (MIDI bank, MIDI program) pairs with arbitrary
698 (engine type, instrument file, file index) triplets which will be
699 loaded on the respective channel when such MIDI program change
700 messages arrive, beside that, each entry allows to define a life-time
701 strategy for the instrument, so the user can define whether the
702 instrument should i.e. be permanently loaded (to be able to switch
703 quickly among sounds) or i.e. loaded just on demand when the
704 respective program change arrives (to safe RAM space), as well as a
705 global volume factor for each entry, so the user can adjust the volume
706 dynamic of his mapped instrument collection without having to modify
707 the instrument files, also one can manage arbitrary amount of such
708 MIDI instrument maps and assign each sampler channel individually
709 a certain map, so that i.e. separation of normal instruments and
710 drumkits is possible
711 - new notification events for tracking changes to audio/MIDI devices,
712 MIDI instrument maps, MIDI instruments, FX sends, global volume.
713 - sampler was limited to load max. 200 instruments in the background
714 due to a constant size RingBuffer FIFO which is now replaced by a
715 dynamic (unlimited) size std::list FIFO
716 - added FX sends, these allow to route audio signals to arbitrary audio
717 output channels for being processed by external effect processors
718 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
719 controllers
720 - global (sampler wide) volume can now be controlled at runtime
721 - Implemented new, improved notification system
722 - fixed compilation errors regarding OSX
723 (patch by Toshi Nagata)
724 - implemented instruments database
725 - added support for escape sequences to the instruments database
726 - added highly experimental support for on-the-fly instrument editing
727 within the sampler's process (by using instrument editor plugins),
728 you'll notice the new "Registered instrument editors:" message on
729 startup, added a new LSCP command:
730 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
731 to spawn a matching instrument editor for the instrument on the
732 given sampler channel, the plugin path can be overridden at compile
733 time with ./configure --enable-plugin-dir=/some/dir
734 - added experimental code for synchronizing instrument editors hosted
735 in the sampler's process to safely edit instruments while playing
736 without a crash (hopefully) by either suspending single regions
737 wherever possible or if unavoidable whole engine(s)
738 - fixed several issues in fundamental "Thread" class: set scheduling
739 policy and priority on thread level, set a minimum stack size for
740 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
741 threads simply inherited properties of starting thread instead of
742 setting their own policy and priority
743 - minor fix in our automatic stack trace mechanism on crashes, the
744 main process did not wait for the stack trace process to finish
745 its output
746 - fixed some minor memory leaks
747 - reenabled assembly features support, at the moment only for
748 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
749 - minor assembly fix in x86 features detection (don't use the PIC
750 register, to avoid relocations in the text segment at runtime)
751 - POSIX callback functions of Thread.h are hidden
752
753 * MIDI driver:
754 - dispatch bank select (MSB and LSB) messages
755
756 * audio driver:
757 - the ALSA audio output driver parameters now reflect the correct
758 parameter value ranges for the respective selected sound card
759 (patch by Till Wimmer, a bit fixed and extended)
760
761 * Gigasampler format engine:
762 - if a filter is used and EG2 finishes before EG1, let the voice
763 die when EG2 has finished (this fixes a problem with clicks and
764 voice starvation for some gigs)
765 - playback is no longer disabled during instrument loading
766 - all notes playing on a channel that changes its instrument keep
767 playing with the old instrument until they get a note off
768 command
769 - EG fix: a release value of zero could cause noises or crash
770 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
771 - EG fine tuning: when attack is zero the EG starts at a level
772 above max sustain level, which means that there is a decay phase
773 even if sustain is 100%
774 - more EG fixes: the level could sometimes go below zero and cause
775 noises or crashes
776 - minor fix of EGDecay (patch by Toshi Nagata)
777 - fixed compiler error when --enable-override-filter-type was
778 supplied to the configure script (fixes #46)
779 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
780 instead of a fix value
781 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
782 127 (solo mode) only kill voices if the respective mode really
783 changed
784
785 * LSCP server:
786 - fixed compile time error for old Bison versions
787 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
788 - parser now supports extended ASCII character set
789 (up to ASCII code 255, i.e. includes now umlauts and accents)
790 - filename arguments in LSCP commands now allow to use escape
791 sequences, that is directly literal as one of: \', \", \\, \n, \r,
792 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
793 code value like \xf2) (fixes bug #24)
794 - the following LSCP commands now also support escape sequences for at
795 least one of their text-based parameters (i.e. name, description):
796 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
797 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
798 "SET DB_INSTRUMENT_DIRECTORY NAME",
799 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
800 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
801 "FIND DB_INSTRUMENT_DIRECTORIES"
802 - returns verbose syntax errors (line and column where syntax error
803 occured, the unexpected character and the actually expected, possible
804 character(s), the latter only if less than 5 possibilities)
805 - made sure that LSCP syntax is not affected by gigedit locale
806 settings
807 - bugfix regarding strings parameter lists: all comma separated lists
808 of strings were treated as being one string containing commas
809 (fixes #57)
810
811 * Bug fixes:
812 - fixed crash occurring on certain LSCP scripts (Bug 39)
813 - another thread safety fix for lscp "load engine" and "set
814 channel audio output device"
815 - fixed a crash which occurs when reassigning the same engine
816 on a sampler channel with connected MIDI device
817 - fixed a crash which occurs when changing the number of ports of a MIDI
818 device connected to a sampler channel to number less then or equal
819 to the index of the port to which the sampler channel is connected.
820 - The previous bindings were not been disconnected when altering
821 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
822 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
823 - The active stream/voice count statistic was incorrect.
824 - notification events were not been sent for some sampler
825 channel changes
826 - added default min and max values to restrict the number of allowed
827 audio output channels and MIDI input ports
828 - the connection to the PCM interface is now closed when destroying
829 an audio output device
830 - files with slash in their path or filename could not be loaded
831
832 * test cases:
833 - updated and fixed (haven't been touched in a while)
834
835 Version 0.4.0 (24 November 2006)
836
837 * packaging changes:
838 - changed deprecated copyright attribute to license; added ldconfig
839 to post-(un)install steps; added devel package for liblinuxsampler;
840 to linuxsampler.spec (RPM)
841 - install necessary development header files for allowing 3rd party
842 applications to link against liblinuxsampler
843 - liblinuxsampler's API documentation can be generated with 'make docs'
844 (Doxygen required)
845 - added benchmark to automatically detect the best triangle LFO
846 implementation (currently either an integer math solution or a
847 di-harmonic approximation), automatic detection can be overriden
848 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
849 configure script argument though (mandatory for cross-compilation)
850 - do not automatically pick optimized gcc flags if the user already
851 provided some on his own (as CXXFLAGS)
852 - added compile time option to disable processing of All-Notes-Off MIDI
853 messages
854 - added compile time options to allow disabling the various audio and
855 MIDI drivers
856 - fixed automatic GCC CPU switch detection on PPC
857 (patch by Ebrahim Mayat)
858
859 * Gigasampler format engine:
860 - extensive synthesis optimization
861 (reimplementation of EGs and LFO(s), removed synthesis parameter
862 prerendering and the synthesis parameter matrix in general, splitting
863 each audio fragment into subfragments now where each subfragment uses
864 constant pitch and filter coefficients. The volume coefficient is
865 linearly interpolated inside a subfragment, unless
866 --disable-interpolate-volume is set.)
867 - fine tuning of the EG modulation parameters
868 - improved filter cutoff calculation by adding support for the
869 following gig parameters: Cutoff freq (used when no cutoff
870 controller is defined), Control invert, Minimum cutoff, Velocity
871 curve and Velocity range. The keyboard tracking now scales
872 cutoff frequency instead of resonance.
873 - added support for gig parameter Resonance.
874 - fixed bug in sysex handling (patch by Juan Linietsky)
875 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
876 which can be overridden with --enable-global-attenuation
877 - EG fixes: made the length of "attack hold" stage more
878 accurate. Release stage can now start before attack stage
879 ends. Cancel release didn't work when sustain was zero. Attack
880 time now has a minimal value to prevent clicks.
881 - fixed pitch changes larger than one octave
882 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
883 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
884 all modes can be altered via standard GM messages, that is CC5 for
885 altering portamento time, CC65 for enabling / disabling portamento
886 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
887 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
888 parameter) and crossfade
889 - added support for the "attenuation controller threshold" gig
890 parameter
891 - added smoothing of volume changes caused by control change
892 messages
893 - sample loop parameters are now taken from the DimensionRegion
894 instead of the wave chunk
895 - fixed keyswitching for v3 gigs with a number of keyswitch splits
896 not equal to a power of two
897 - reimplementation of the filter algorithm. The new filter is more
898 accurate and supports all gig filter types, including bandreject
899 and lowpass turbo.
900 - real support for 24 bit samples - samples are not truncated to
901 16 bits anymore
902 - support for aftertouch (channel pressure, not polyphonic
903 aftertouch)
904 - LFO1 behaviour fixed (dampening from max volume instead of
905 amplifying from 0)
906
907 * LSCP server:
908 - fixed application exit on broken pipe error (fixes bug #20)
909 - fixed the notification messages delay due to lack of
910 network activity (fixes bug #26)
911 - fixed parser bug which occured on space(s) within device parameters
912 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
913
914 * audio driver:
915 - added aRts audio output driver (by no means RT safe)
916
917 * MIDI driver:
918 - fixed legacy sysex code which caused dispatching of MIDI SysEx
919 messages several times instead of once
920 - API extension for MIDI drivers which already supply exact time stamps
921 for events (i.e. for offline rendering based MIDI drivers)
922 - added checks for bad MIDI data
923
924 * linuxsampler application:
925 - show available sampler engine types on startup
926
927 * general changes:
928 - support for muting sampler channels and solo mode of the same, two new
929 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
930 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
931 introduced for this, the behavior is the same like on a mixer console
932 (patch by Grigor Iliev, a bit adjusted). Also added configure option
933 --enable-process-muted-channels which can be used to enable the
934 processing of muted channels.
935 - support for sostenuto pedal
936 - support for monitoring the total number of active voices
937 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
938 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
939 - fixed some memory management errors
940 - fixed some concurrency problems that could lead to crashes when
941 LSCP commands were executed
942 - fixed crash when instrument loading failed previously on the same
943 sampler channel (fixes bug #36)
944
945 Version 0.3.3 (15 July 2005)
946
947 * packaging changes:
948 - fixed compilation with gcc 4.0
949
950 * Gigasampler format engine:
951 - LFO preprocessing was performed even though the respective LFO was
952 disabled by the instrument patch (minor efficiency fix)
953 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
954 for volume ramp downs in the same fragment (needed for current voice
955 stealing implementation) then simply inform the user with a warning
956 about possible click sounds and reduce the volume ramp down
957 appropriately instead of cancelling the audio device connection
958
959 Version 0.3.2 (24 June 2005)
960
961 * packaging changes:
962 - updated autotools build files to compile on OS X
963 (conditional compilation of CoreMIDI and MidiShare drivers)
964 - hand-crafted assembly optimization code can be disabled with
965 './configure --disable-asm' (definitely not recommended)
966 - fixed 'make dist' rule to include all necessary files
967 - require automake (>= 1.5) for 'make -f Makefile.cvs'
968 (due to 'dist-bzip2' automake option)
969
970 * Gigasampler format engine:
971 - support for the gig parameters for "release velocity response" curves
972 - fine tuning of the EGADSR envelope
973 - volume of release triggered samples now depends on note-on velocity,
974 note length and gig parameter "release trigger decay" instead of
975 note-off velocity.
976 - revised voice stealing
977 (fixes crash and endless loop caused by voice stealing)
978 - don't reset scale tuning on instrument or audio output device change
979 - handle key group conflicts right at the beginning of each fragment
980 instead of when the respective voice is actually launched
981 (fixes undefined behavior if stolen voices belonged to a key group -
982 this case was followed by a "killed voice survived" error message)
983 - fixed minor issue with null/silence samples
984 (those stole voices even though they don't need a voice at all which
985 resulted in "voice stealing didn't work out" messages)
986 - don't reset volume, pan, pitch and MIDI controller values on
987 instrument or audio output device change
988
989 * LSCP server:
990 - fixed some crashes (patch by Grigor Iliev, fixes #19)
991 - fixed LSCP event "CHANNEL_INFO" notification
992 (e.g. did not notify on volume changes or MIDI program change events)
993
994 * linuxsampler application:
995 - added command line parameters --lscp-addr and --lscp-port to override
996 default IP address and port of LSCP server
997
998 Version 0.3.1 (24 May 2005)
999
1000 * initial release
