40
41 * general changes:
42 - Refactoring: moved the independent code from
43 the Gigasampler format engine to base classes
44 - command line option '--profile' is currently disabled, since the
45 respective profiling code is currently broken
46 - Introduced support for optional environment variable
47 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
48 where the sampler shall look for instrument editor plugins
49 (patch by Luis Garrido, slightly modified).
50 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
51 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
52 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
53 note (in this implementation of the sampler its simply hard routed to
54 the 1st effect send of the sampler channel, no matter what the actual
55 effect type is)
56 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
57 note (in this implementation of the sampler its simply hard routed to
58 the 2nd effect send of the sampler channel, no matter what the actual
59 effect type is)
60 - implemented support for internal LADSPA effects
61 - raised limit of program change queue from 100 to 512
62 (as suggested by Alex Stone)
63 - implemented sine LFO, pulse LFO and saw LFO
64 - experimental support for per voice equalization
65 - added command line option --exec-after-init
66 - Introduced new C++ API method:
67 EngineChannel::InstrumentFileName(int index)
68 allowing to retrieve the whole list of files used for the loaded
69 instrument on an engine channel (a.k.a. part). Some GigaStudio
70 instruments for example are splitted over several files like
71 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
72 - Added new C++ API method Sampler::GetGlobalMaxVoices().
73 - Added new C++ API method Sampler::GetGlobalMaxStreams().
74 - Added new C++ API method Sampler::SetGlobalMaxVoices().
75 - Added new C++ API method Sampler::SetGlobalMaxStreams().
76 - Various "const" and "restrict" optimizations.
77 - all engines: add pan CC value to instrument pan parameter before
78 applying panning, instead of using two separate pan functions in
79 series (#182)
80 - added a lock guard class for exception safe mutex handling and
81 used it everywhere appropriate
82 - Immediately apply scale tuning changes to active voices.
83 - Exposed scale tuning to C++ API (along to the already existing standard
84 SysEx way).
85 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
86 and broken for ppc64. (Seq_cst loads and stores are actually not
87 used in LS, so the bug wasn't noticable.)
88 - lsatomic.h: added ARMv7 support
89 - Added support for multiple MIDI input ports per sampler channel (and
90 added various new C++ methods for this new feature / design change, old
91 C++ API methods for managing SamplerChannel's MIDI inputs are now marked
92 as deprecated but are still there and should provide full behavior
93 backward compatibility).
94 - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
95 unsafe and caused compilation error with clang 2.x).
96 - Bugfix: only process the latest MIDI program change event.
97 - Introducing the LSCP shell, which provides convenient control of the
98 sampler from the command line by providing LSCP aware features.
99

105 key
106 - bugfix: pitch LFO controller "internal+aftertouch" was broken
107 - bugfix: filter keyboard tracking was broken
108 - filter performance fix (an unnecessary copy was made of the
109 filter parameters in each sub fragment)
110 - handle special case when pan parameter in gig file has max or
111 min value
112 - Exclusive Groups: don't ever stop voices of the same note,
113 doesn't sound naturally with a drumkit
114 - fixed EG1 modulation when attack or release is zero
115

414 - Windows: disabled the previous thread fix on non-Mac systems, as
415 it caused hanging threads on Windows
416 - Fixed possible crashes due to corrupted MIDI/audio device list
417 after MIDI/audio device creation failure
418 - When creating MIDI instrument map entries with "PERSISTENT" type, the
419 instruments were uselessly precached with zero samples, however it still
420 took the full preloading time and on 1st program change the respective
421 instrument was completely reloaded again.
422 - fixed handling of rapid bank select and program change messages
423 sent to the same sampler channel (patch from the Open Octave
424 project, slightly adjusted)

443 crashes and noise on such transitions).
444 - ignore missing LADSPA paths without ignoring valid LADSPA paths
445 (fixes #208)
446
447 Version 1.0.0 (31 July 2009)
448
449 * packaging changes:
450 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
451 causing e.g. the libgig test to fail when
452 "./configure --disable-jack-driver" was used
453 (patch by Alexis Ballier)
454 - fixed compilation with gcc 4.3
455 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
456 - fixed configure so it detects x86_64 (#107)
457 - fixes for building with newer MinGW versions
458 - fix for building with bison 2.4 (#111)
459 - fixed building with libgig installed in a non-standard directory
460 - minor fix in configure for mmsystem.h detection on MinGW
461 - Windows: look for editor plugins and Fantasia using base
462 directory of liblinuxsampler dll (look in the same directory and one
463 directory above)
464 - configure script fix: removed unconditional use of SSE
465 - fixed building with sqlite installed in a non-standard directory
466 - when cross-compiling, don't try to create instruments.db
467 - fix for new mingw-w64 version, which has usleep
468
469 * general changes:
470 - bugfix: on some POSIX systems instrument editor plugins refused to
471 load as we used a non-portable Linux specific struct field
472 (fixes bug #70, patch by Ronald Baljeu)
473 - fixed endless loop which occured when loading an instrument editor
474 plugin DLL on Windows systems failed
475 - fixed memory leaks that occurred when liblinuxsampler was unloaded
476 - optimized the SynchronizedConfig class so it doesn't wait
477 unnecessarily long after an update
478 - added support for notifying instrument editors on note-on / note-off
479 events (e.g. to highlight the pressed keys on the virtual keyboard
480 of gigedit)
481 - added support for triggering notes by instrument editors (see above)
482 - be verbose on DLL load errors (on Linux)
483 - fixed di-harmonic triangle LFO implementation (this LFO implementation
484 is only used by very few systems, most pick the int math
485 implementation, which is usually faster)
486 - fixes for audio drivers with varying buffer sizes
487 - experimental support for running LinuxSampler as a DSSI, LV2 and
488 VST plugin
489 - notification events for stream/voice count statistics are now sent
490 only when there are actual changes
491 - added memory ordering constraints to improve stability on
492 multi-core and multi-cpu systems
493 - maximum voices and disk streams can now be altered at runtime
494 - fixed CPU feature detection on x86_64 (maybe fixes #108)
495 - automatic stacktrace mechanism is now turned off by default and can
496 be switched on by command line option "--stacktrace" (the automatic
497 stacktrace mechanism seems to be broken on most systems at the moment)
498 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
499 a pointer to the launched InstrumentEditor object
500 - added optional 3rd party user data parameter for following
501 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
502 InstrumentEditor::Launch(),
503 InstrumentManager::LaunchInstrumentEditor()
504 - theoretical fix: made SynchronizedConfig follow C++0x memory
505 model more strictly
506 - fixes for using large audio device buffers
507 - Windows: add the installation directory to the DLL search path
508 when loading an editor plugin (solves problems with VST and
509 gigedit on systems with other GTK versions installed)
510 - updated linuxsampler man page
511
512 * audio driver:
513 - removed the nonsense audio channel constraint (which was hard coded to
514 max. 100 audio channels) for most audio drivers
515 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
516 opposed to the LSCP specs
517 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
518 reflected the wrong value
519 - fixed a memory management bug in ASIO driver
520 - Makefile fix: JACK_CFLAGS wasn't used
521 - JACK: use jack_client_open instead of the deprecated
522 jack_client_new
523 - added (experimental) CoreAudio driver
524 - applied old fixes to the ASIO driver that were included in the
525 previous binary release but accidentally never committed to CVS
526 (fixes #117)
527 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
528 win64)
529 - VST: added support for sample rate and buffer size changes
530 - VST: close editor (Fantasia) when the VST is removed
531 - VST: avoid opening Fantasia more than once for each VST instance
532 - VST: export main function as "main" on Linux too (fix for
533 energyXT)
534 - VST: changed number of output channels from one stereo to 16
535 stereo
536 - added channel routing, fxsends and midi maps to the settings
537 stored in the plugin state
538 - performance optimization of AudioChannel::MixTo() and
539 AudioChannel::CopyTo() methods using GCC vector exensions
540 (if available)
541 - ASIO fixes: avoid initializing the device twice, avoid throwing
542 exception when getting parameters from a disconnected device
543
544 * MIDI driver:
545 - added JACK MIDI driver
546 - dispatch bank select as ordinary CC as well, the user might seriously
547 want to (mis)use it for some purpose ("fixed" in all current MIDI
548 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
549 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
550 CoreMidi or AU
551 - fixed mingw-w64 compilation error in MME driver
552 - made program change handling in MIDI thread real-time safe by
553 moving the logic to a non-RT thread
554 - fixed minor memory leak in ALSA driver
555
556 * instruments database:
557 - avoid time consuming samples scanning when adding instruments
558 to the instruments database
559 - added support for handling lost files in the instruments database
560 - Implemented option for adding instruments in separate directories
561 in the instruments database
562 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
563 - work-around for missing fnmatch function on Windows to make
564 instrument database compilable
565 - added instrument database support on Windows
566 works with both standalone mode and VST plugin.
567 the instruments DB file is located in
568 %USERPROFILE%\.linuxsampler\instruments.db which allows different
569 databases for each windows user
570 if no DB is present it automatically creates the .linuxsampler subdir
571 and then creates an empty DB
572 - fixed recursive import, which was broken on Windows
573
574 * Gigasampler format engine:
575 - fixed a memory leak that could happen when a channel was deleted
576 while notes were playing
577 - made it possible to load an instrument even if the audio thread
578 isn't running
579 - added partial support for the "Controller Triggered" MIDI rule,
580 enough for piano gigs with pedal noise samples
581 - minor fix: only mark FX sends as being modified if really the
582 respective FX send MIDI controller was used
583 - added support for GM global device volume SysEx message
584 (can be selected at compile time to either apply globally to the
585 whole sampler [default] or only to the sampler channels that are
586 connected to the respective MIDI input port the SysEx message arrived
587 on)
588 - bugfix: notes triggered at position 0 in the audio buffer were
589 sometimes wrongly killed in the same buffer, causing no sound to
590 be played
591 - added support for chromatic / drumkit mode Roland GS Sysex message
592 which is usally used to switch a part between chromatic sounds and
593 drumkit sounds (as opposed to their common default setting of MIDI
594 part 10 being a drumkit part and all other ones chromatic parts), in
595 LS however one can switch between the first 16 MIDI instrument maps
596 defined for the sampler
597 - made it possible to create multiple sample channels even if the
598 audio thread isn't running
599 - fixed crash when removing channel with active voices (#116)
600 - bugfix: on sample reference changes (instrument editor), only
601 un-cache the respective sample if it's really not used by any
602 sampler engine anymore
603 - re-cache samples in case they were changed by an instrument editor,
604 e.g. when a sample was added while playing (#82)
605 - fixed hanging notes which occured when note-off event had the exact
606 same time stamp as the voice's note-on event and occured both in the
607 same audio fragment cycle (fixes bug #112)
608 - added support for the "fine tune" and "pitch bend range"
609 instrument-level gig parameters
610 - fixed minor artifacts in pitch bend handling
611 - added support for GS Reset SysEx message
612 - allow gig files to use unlimited downward pitch shifting
613 - added a limit check for upward pitch shifting
614 - bugfix: sometimes, when playing a note twice fast, the second
615 note was silent
616 - fixed crash happening when a pitch bend event arrived at the
617 same time a new instrument was loading
618
619 * LSCP server:
620 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
621 react on MIDI data arriving on certain sampler channels (so far only
622 Note-On and Note-Off events are sent via this LSCP event)
623 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
624 react on MIDI data arriving on certain MIDI input devices (so far only
625 Note-On and Note-Off events are sent via this LSCP event)
626 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
627 SET DB_INSTRUMENT FILE_PATH
628 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
629 frontends to send MIDI messages to specific sampler channel
630 - added two additional fields to GET FILE INSTRUMENT INFO command -
631 KEY_BINDINGS and KEYSWITCH_BINDINGS
632 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
633 was incorrect
634 - Optimized the retrieval of the MIDI instrument mappings
635 - added new LSCP command "SET VOICES" to globally alter the maximum
636 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
637 be triggered respectively
638 - added new LSCP command "SET STREAMS" to globally alter the maximum
639 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
640 which will be triggered respectively
641 - bugfix: retry if "select" returns EINTR (this fixes a crash when
642 a gigedit file dialog is opened)
643 - close all connections when LSCPServer is deleted
644 - hard close of all sockets on exit
645 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
646 driver
647
648 * Bug fixes:
649 - fixed a crash which occurs when removing a sampler channel waiting
650 to start instrument loading after another channel
651 - fixed a crash which occurs when removing a sampler channel with
652 instrument loading in progress (bug #113)
653 - fixed termination caused by uncaught exception when adding MIDI
654 instrument with PERSISTENT load mode
655 - fixed possible iterator invalidations when resetting the sampler
656 - fixed memory leaks when issuing the following LSCP commands:
657 GET AUDIO_OUTPUT_DRIVER INFO
658 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
659 GET MIDI_INPUT_DRIVER INFO
660 GET MIDI_INPUT_DRIVER_PARAMETER INFO
661 - fixed possible compilation error when sqlite is not present
662 - fixed orphaned pointers when setting maximum voices limit (bug #118)
663 - fixed crash when changing the audio output device of a sampler
664 channel with loaded instrument and start playing notes
665 - fixed endless loop in Engine::SuspendAll() (bug #120)
666 - fixed a low-level atomic load function that was broken on 64-bit
667 PowerPC, which probably could cause crashes on that platform
668 - fixed a memory management error which could cause a crash when a
669 plugin was unloaded
670 - bugfix: two private structs had the same name, which could cause
671 problems if the linker chose the wrong constructor
672 - fixed low-level ConditionServer usage bug that caused lockups on
673 Windows
674
675
676 Version 0.5.1 (6 December 2007)
677
678 * packaging changes:
679 - added autoconf checks for pthread library
680 - added autoconf check for pthread bug found on certain NPTL-enabled
681 glibc versions (see Gentoo bug report #194076)
682 - added autoconf checks for MS Windows
683
684 * general changes:
685 - bugfix: the thread used by an editor plugin didn't die when the
686 editor closed
687 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
688 out all the space. operator--() did not apply size_mask after
689 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
690 order to avoid problems with the _NonVolatileReader functions.
691 - bugfix: Stream.h: added a missing divide by BytesPerSample in
692 GetWriteSpace(). Since this function is currently only used in
693 the stream's qsort() compare function, it didn't trigger any
694 bugs.
695 - Resampler.h, Synthesizer.h: cubic interpolation now works in
696 24bit mode too. Faster method to read 24bit words on little
697 endian machines (x86): replaced 3 byte reads + shifts with a 1
698 unaligned 32bit read and shift
699 - experimental support for MS Windows (MIDI input via MME, AUDIO
700 output via ASIO)
701 - made handling of SIGINT signal (Ctrl-C) a bit more robust
702 - support for monitoring the total number of active disk streams
703 (new LSCP commands: GET TOTAL_STREAM_COUNT,
704 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
705
706 * AUDIO driver:
707 - added Windows ASIO low latency audio driver
708
709 * MIDI driver:
710 - added MME Windows MIDI driver
711
712 * LSCP server:
713 - added support for Windows style path / filenames, however with
714 forward slash path separators instead of backslash
715 (i.e. "C:/foo/bar.gig")
716 - allow naughty liblscp to send non-string device parameters within
717 apostrophes as well
718 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
719 "LIST FILE INSTRUMENTS <file>" and
720 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
721 about an arbitrary instrument file on the system where the sampler is
722 running on
723
724 Version 0.5.0 (15 October 2007)
725
726 * packaging changes:
727 - config.h is not going to be installed along with liblinuxsampler's
728 API header files anymore
729 - only the API relevant header (and source) files will be exported to
730 the Doxygen API documentation (explicitly listed in Doxyfile.in)
731 - added completely new XCode project files for Mac OSX which is now
732 capable to execute our autoconf environment, thus no need anymore
733 to maintain the compile time configuration file (osx/version.h) for
734 OSX manually (patch by Toshi Nagata)
735 - fixed buggy boolean --enable-foo / --disable-foo configure script
736 parameters
737 - global.h now only covers global definitions that are needed for the
738 C++ API header files, all implementation internal global definitions
739 are now in global_private.h
740 - atomic.h is not exposed to the C++ API anymore
741 - no need to include config.h anymore for using LS's API header files
742 - fixed warnings in API doc generation
743
744 * general changes:
745 - replaced the old, confusing MIDI program change mechanism by a
746 flexible MIDI instrument mapper which allows to map arbitrary
747 (MIDI bank, MIDI program) pairs with arbitrary
748 (engine type, instrument file, file index) triplets which will be
749 loaded on the respective channel when such MIDI program change
750 messages arrive, beside that, each entry allows to define a life-time
751 strategy for the instrument, so the user can define whether the
752 instrument should i.e. be permanently loaded (to be able to switch
753 quickly among sounds) or i.e. loaded just on demand when the
754 respective program change arrives (to safe RAM space), as well as a
755 global volume factor for each entry, so the user can adjust the volume
756 dynamic of his mapped instrument collection without having to modify
757 the instrument files, also one can manage arbitrary amount of such
758 MIDI instrument maps and assign each sampler channel individually
759 a certain map, so that i.e. separation of normal instruments and
760 drumkits is possible
761 - new notification events for tracking changes to audio/MIDI devices,
762 MIDI instrument maps, MIDI instruments, FX sends, global volume.
763 - sampler was limited to load max. 200 instruments in the background
764 due to a constant size RingBuffer FIFO which is now replaced by a
765 dynamic (unlimited) size std::list FIFO
766 - added FX sends, these allow to route audio signals to arbitrary audio
767 output channels for being processed by external effect processors
768 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
769 controllers
770 - global (sampler wide) volume can now be controlled at runtime
771 - Implemented new, improved notification system
772 - fixed compilation errors regarding OSX
773 (patch by Toshi Nagata)
774 - implemented instruments database
775 - added support for escape sequences to the instruments database
776 - added highly experimental support for on-the-fly instrument editing
777 within the sampler's process (by using instrument editor plugins),
778 you'll notice the new "Registered instrument editors:" message on
779 startup, added a new LSCP command:
780 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
781 to spawn a matching instrument editor for the instrument on the
782 given sampler channel, the plugin path can be overridden at compile
783 time with ./configure --enable-plugin-dir=/some/dir
784 - added experimental code for synchronizing instrument editors hosted
785 in the sampler's process to safely edit instruments while playing
786 without a crash (hopefully) by either suspending single regions
787 wherever possible or if unavoidable whole engine(s)
788 - fixed several issues in fundamental "Thread" class: set scheduling
789 policy and priority on thread level, set a minimum stack size for
790 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
791 threads simply inherited properties of starting thread instead of
792 setting their own policy and priority
793 - minor fix in our automatic stack trace mechanism on crashes, the
794 main process did not wait for the stack trace process to finish
795 its output
796 - fixed some minor memory leaks
797 - reenabled assembly features support, at the moment only for
798 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
799 - minor assembly fix in x86 features detection (don't use the PIC
800 register, to avoid relocations in the text segment at runtime)
801 - POSIX callback functions of Thread.h are hidden
802
803 * MIDI driver:
804 - dispatch bank select (MSB and LSB) messages
805
806 * audio driver:
807 - the ALSA audio output driver parameters now reflect the correct
808 parameter value ranges for the respective selected sound card
809 (patch by Till Wimmer, a bit fixed and extended)
810
811 * Gigasampler format engine:
812 - if a filter is used and EG2 finishes before EG1, let the voice
813 die when EG2 has finished (this fixes a problem with clicks and
814 voice starvation for some gigs)
815 - playback is no longer disabled during instrument loading
816 - all notes playing on a channel that changes its instrument keep
817 playing with the old instrument until they get a note off
818 command
819 - EG fix: a release value of zero could cause noises or crash
820 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
821 - EG fine tuning: when attack is zero the EG starts at a level
822 above max sustain level, which means that there is a decay phase
823 even if sustain is 100%
824 - more EG fixes: the level could sometimes go below zero and cause
825 noises or crashes
826 - minor fix of EGDecay (patch by Toshi Nagata)
827 - fixed compiler error when --enable-override-filter-type was
828 supplied to the configure script (fixes #46)
829 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
830 instead of a fix value
831 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
832 127 (solo mode) only kill voices if the respective mode really
833 changed
834
835 * LSCP server:
836 - fixed compile time error for old Bison versions
837 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
838 - parser now supports extended ASCII character set
839 (up to ASCII code 255, i.e. includes now umlauts and accents)
840 - filename arguments in LSCP commands now allow to use escape
841 sequences, that is directly literal as one of: \', \", \\, \n, \r,
842 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
843 code value like \xf2) (fixes bug #24)
844 - the following LSCP commands now also support escape sequences for at
845 least one of their text-based parameters (i.e. name, description):
846 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
847 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
848 "SET DB_INSTRUMENT_DIRECTORY NAME",
849 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
850 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
851 "FIND DB_INSTRUMENT_DIRECTORIES"
852 - returns verbose syntax errors (line and column where syntax error
853 occured, the unexpected character and the actually expected, possible
854 character(s), the latter only if less than 5 possibilities)
855 - made sure that LSCP syntax is not affected by gigedit locale
856 settings
857 - bugfix regarding strings parameter lists: all comma separated lists
858 of strings were treated as being one string containing commas
859 (fixes #57)
860
861 * Bug fixes:
862 - fixed crash occurring on certain LSCP scripts (Bug 39)
863 - another thread safety fix for lscp "load engine" and "set
864 channel audio output device"
865 - fixed a crash which occurs when reassigning the same engine
866 on a sampler channel with connected MIDI device
867 - fixed a crash which occurs when changing the number of ports of a MIDI
868 device connected to a sampler channel to number less then or equal
869 to the index of the port to which the sampler channel is connected.
870 - The previous bindings were not been disconnected when altering
871 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
872 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
873 - The active stream/voice count statistic was incorrect.
874 - notification events were not been sent for some sampler
875 channel changes
876 - added default min and max values to restrict the number of allowed
877 audio output channels and MIDI input ports
878 - the connection to the PCM interface is now closed when destroying
879 an audio output device
880 - files with slash in their path or filename could not be loaded
881
882 * test cases:
883 - updated and fixed (haven't been touched in a while)
884
885 Version 0.4.0 (24 November 2006)
886
887 * packaging changes:
888 - changed deprecated copyright attribute to license; added ldconfig
889 to post-(un)install steps; added devel package for liblinuxsampler;
890 to linuxsampler.spec (RPM)
891 - install necessary development header files for allowing 3rd party
892 applications to link against liblinuxsampler
893 - liblinuxsampler's API documentation can be generated with 'make docs'
894 (Doxygen required)
895 - added benchmark to automatically detect the best triangle LFO
896 implementation (currently either an integer math solution or a
897 di-harmonic approximation), automatic detection can be overriden
898 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
899 configure script argument though (mandatory for cross-compilation)
900 - do not automatically pick optimized gcc flags if the user already
901 provided some on his own (as CXXFLAGS)
902 - added compile time option to disable processing of All-Notes-Off MIDI
903 messages
904 - added compile time options to allow disabling the various audio and
905 MIDI drivers
906 - fixed automatic GCC CPU switch detection on PPC
907 (patch by Ebrahim Mayat)
908
909 * Gigasampler format engine:
910 - extensive synthesis optimization
911 (reimplementation of EGs and LFO(s), removed synthesis parameter
912 prerendering and the synthesis parameter matrix in general, splitting
913 each audio fragment into subfragments now where each subfragment uses
914 constant pitch and filter coefficients. The volume coefficient is
915 linearly interpolated inside a subfragment, unless
916 --disable-interpolate-volume is set.)
917 - fine tuning of the EG modulation parameters
918 - improved filter cutoff calculation by adding support for the
919 following gig parameters: Cutoff freq (used when no cutoff
920 controller is defined), Control invert, Minimum cutoff, Velocity
921 curve and Velocity range. The keyboard tracking now scales
922 cutoff frequency instead of resonance.
923 - added support for gig parameter Resonance.
924 - fixed bug in sysex handling (patch by Juan Linietsky)
925 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
926 which can be overridden with --enable-global-attenuation
927 - EG fixes: made the length of "attack hold" stage more
928 accurate. Release stage can now start before attack stage
929 ends. Cancel release didn't work when sustain was zero. Attack
930 time now has a minimal value to prevent clicks.
931 - fixed pitch changes larger than one octave
932 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
933 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
934 all modes can be altered via standard GM messages, that is CC5 for
935 altering portamento time, CC65 for enabling / disabling portamento
936 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
937 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
938 parameter) and crossfade
939 - added support for the "attenuation controller threshold" gig
940 parameter
941 - added smoothing of volume changes caused by control change
942 messages
943 - sample loop parameters are now taken from the DimensionRegion
944 instead of the wave chunk
945 - fixed keyswitching for v3 gigs with a number of keyswitch splits
946 not equal to a power of two
947 - reimplementation of the filter algorithm. The new filter is more
948 accurate and supports all gig filter types, including bandreject
949 and lowpass turbo.
950 - real support for 24 bit samples - samples are not truncated to
951 16 bits anymore
952 - support for aftertouch (channel pressure, not polyphonic
953 aftertouch)
954 - LFO1 behaviour fixed (dampening from max volume instead of
955 amplifying from 0)
956
957 * LSCP server:
958 - fixed application exit on broken pipe error (fixes bug #20)
959 - fixed the notification messages delay due to lack of
960 network activity (fixes bug #26)
961 - fixed parser bug which occured on space(s) within device parameters
962 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
963
964 * audio driver:
965 - added aRts audio output driver (by no means RT safe)
966
967 * MIDI driver:
968 - fixed legacy sysex code which caused dispatching of MIDI SysEx
969 messages several times instead of once
970 - API extension for MIDI drivers which already supply exact time stamps
971 for events (i.e. for offline rendering based MIDI drivers)
972 - added checks for bad MIDI data
973
974 * linuxsampler application:
975 - show available sampler engine types on startup
976
977 * general changes:
978 - support for muting sampler channels and solo mode of the same, two new
979 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
980 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
981 introduced for this, the behavior is the same like on a mixer console
982 (patch by Grigor Iliev, a bit adjusted). Also added configure option
983 --enable-process-muted-channels which can be used to enable the
984 processing of muted channels.
985 - support for sostenuto pedal
986 - support for monitoring the total number of active voices
987 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
988 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
989 - fixed some memory management errors
990 - fixed some concurrency problems that could lead to crashes when
991 LSCP commands were executed
992 - fixed crash when instrument loading failed previously on the same
993 sampler channel (fixes bug #36)
994
995 Version 0.3.3 (15 July 2005)
996
997 * packaging changes:
998 - fixed compilation with gcc 4.0
999
1000 * Gigasampler format engine:
1001 - LFO preprocessing was performed even though the respective LFO was
1002 disabled by the instrument patch (minor efficiency fix)
1003 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1004 for volume ramp downs in the same fragment (needed for current voice
1005 stealing implementation) then simply inform the user with a warning
1006 about possible click sounds and reduce the volume ramp down
1007 appropriately instead of cancelling the audio device connection
1008
1009 Version 0.3.2 (24 June 2005)
1010
1011 * packaging changes:
1012 - updated autotools build files to compile on OS X
1013 (conditional compilation of CoreMIDI and MidiShare drivers)
1014 - hand-crafted assembly optimization code can be disabled with
1015 './configure --disable-asm' (definitely not recommended)
1016 - fixed 'make dist' rule to include all necessary files
1017 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1018 (due to 'dist-bzip2' automake option)
1019
1020 * Gigasampler format engine:
1021 - support for the gig parameters for "release velocity response" curves
1022 - fine tuning of the EGADSR envelope
1023 - volume of release triggered samples now depends on note-on velocity,
1024 note length and gig parameter "release trigger decay" instead of
1025 note-off velocity.
1026 - revised voice stealing
1027 (fixes crash and endless loop caused by voice stealing)
1028 - don't reset scale tuning on instrument or audio output device change
1029 - handle key group conflicts right at the beginning of each fragment
1030 instead of when the respective voice is actually launched
1031 (fixes undefined behavior if stolen voices belonged to a key group -
1032 this case was followed by a "killed voice survived" error message)
1033 - fixed minor issue with null/silence samples
1034 (those stole voices even though they don't need a voice at all which
1035 resulted in "voice stealing didn't work out" messages)
1036 - don't reset volume, pan, pitch and MIDI controller values on
1037 instrument or audio output device change
1038
1039 * LSCP server:
1040 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1041 - fixed LSCP event "CHANNEL_INFO" notification
1042 (e.g. did not notify on volume changes or MIDI program change events)
1043
1044 * linuxsampler application:
1045 - added command line parameters --lscp-addr and --lscp-port to override
1046 default IP address and port of LSCP server
1047
1048 Version 0.3.1 (24 May 2005)
1049
1050 * initial release
