16 configure
17 - Mac OS X: Makefile fix for the install-strip target
18 - fixed compilation with gcc 4.7

34
35 * general changes:
36 - Refactoring: moved the independent code from
37 the Gigasampler format engine to base classes
38 - command line option '--profile' is currently disabled, since the
39 respective profiling code is currently broken
40 - Introduced support for optional environment variable
41 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
42 where the sampler shall look for instrument editor plugins
43 (patch by Luis Garrido, slightly modified).
44 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
45 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
46 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
47 note (in this implementation of the sampler its simply hard routed to
48 the 1st effect send of the sampler channel, no matter what the actual
49 effect type is)
50 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
51 note (in this implementation of the sampler its simply hard routed to
52 the 2nd effect send of the sampler channel, no matter what the actual
53 effect type is)
54 - implemented support for internal LADSPA effects
55 - raised limit of program change queue from 100 to 512
56 (as suggested by Alex Stone)
57 - implemented sine LFO, pulse LFO and saw LFO
58 - experimental support for per voice equalization
59 - added command line option --exec-after-init
60 - Introduced new C++ API method:
61 EngineChannel::InstrumentFileName(int index)
62 allowing to retrieve the whole list of files used for the loaded
63 instrument on an engine channel (a.k.a. part). Some GigaStudio
64 instruments for example are splitted over several files like
65 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
66 - Added new C++ API method Sampler::GetGlobalMaxVoices().
67 - Added new C++ API method Sampler::GetGlobalMaxStreams().
68 - Added new C++ API method Sampler::SetGlobalMaxVoices().
69 - Added new C++ API method Sampler::SetGlobalMaxStreams().
70 - Various "const" and "restrict" optimizations.
71 - all engines: add pan CC value to instrument pan parameter before
72 applying panning, instead of using two separate pan functions in
73 series (#182)
74 - added a lock guard class for exception safe mutex handling and
75 used it everywhere appropriate
76 - Immediately apply scale tuning changes to active voices.
77 - Exposed scale tuning to C++ API (along to the already existing standard
78 SysEx way).
79 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
80 and broken for ppc64. (Seq_cst loads and stores are actually not
81 used in LS, so the bug wasn't noticable.)
82 - lsatomic.h: added ARMv7 support
83
84 * Gigasampler format engine:
85 - implemented the "round robin keyboard" dimension
86 - fixed round robin and random dimensions for cases when number of
87 dimension zones is not a power of two
88 - made round robin use a counter for each region instead of each
89 key
90 - bugfix: pitch LFO controller "internal+aftertouch" was broken
91 - bugfix: filter keyboard tracking was broken
92 - filter performance fix (an unnecessary copy was made of the
93 filter parameters in each sub fragment)
94 - handle special case when pan parameter in gig file has max or
95 min value
96 - Exclusive Groups: don't ever stop voices of the same note,
97 doesn't sound naturally with a drumkit
98 - fixed EG1 modulation when attack or release is zero
99
100 * SFZ format engine:
101 - Initial implementation (not usable yet)
102 - added support for v2 multiple stage envelope generators

112 more compatible
113 - added support for trigger=release and rt_decay
114 - added support for off_mode=normal
115 - added support for random, seq_position, seq_length and volume

413 - fixed erroneous error message piping in VoiceBase.h
414 (labelled "Disk stream not available in time")
415 - Update effects on sample rate & period size changes (to avoid
416 crashes and noise on such transitions).
417
418 Version 1.0.0 (31 July 2009)
419
420 * packaging changes:
421 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
422 causing e.g. the libgig test to fail when
423 "./configure --disable-jack-driver" was used
424 (patch by Alexis Ballier)
425 - fixed compilation with gcc 4.3
426 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
427 - fixed configure so it detects x86_64 (#107)
428 - fixes for building with newer MinGW versions
429 - fix for building with bison 2.4 (#111)
430 - fixed building with libgig installed in a non-standard directory
431 - minor fix in configure for mmsystem.h detection on MinGW
432 - Windows: look for editor plugins and Fantasia using base
433 directory of liblinuxsampler dll (look in the same directory and one
434 directory above)
435 - configure script fix: removed unconditional use of SSE
436 - fixed building with sqlite installed in a non-standard directory
437 - when cross-compiling, don't try to create instruments.db
438 - fix for new mingw-w64 version, which has usleep
439
440 * general changes:
441 - bugfix: on some POSIX systems instrument editor plugins refused to
442 load as we used a non-portable Linux specific struct field
443 (fixes bug #70, patch by Ronald Baljeu)
444 - fixed endless loop which occured when loading an instrument editor
445 plugin DLL on Windows systems failed
446 - fixed memory leaks that occurred when liblinuxsampler was unloaded
447 - optimized the SynchronizedConfig class so it doesn't wait
448 unnecessarily long after an update
449 - added support for notifying instrument editors on note-on / note-off
450 events (e.g. to highlight the pressed keys on the virtual keyboard
451 of gigedit)
452 - added support for triggering notes by instrument editors (see above)
453 - be verbose on DLL load errors (on Linux)
454 - fixed di-harmonic triangle LFO implementation (this LFO implementation
455 is only used by very few systems, most pick the int math
456 implementation, which is usually faster)
457 - fixes for audio drivers with varying buffer sizes
458 - experimental support for running LinuxSampler as a DSSI, LV2 and
459 VST plugin
460 - notification events for stream/voice count statistics are now sent
461 only when there are actual changes
462 - added memory ordering constraints to improve stability on
463 multi-core and multi-cpu systems
464 - maximum voices and disk streams can now be altered at runtime
465 - fixed CPU feature detection on x86_64 (maybe fixes #108)
466 - automatic stacktrace mechanism is now turned off by default and can
467 be switched on by command line option "--stacktrace" (the automatic
468 stacktrace mechanism seems to be broken on most systems at the moment)
469 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
470 a pointer to the launched InstrumentEditor object
471 - added optional 3rd party user data parameter for following
472 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
473 InstrumentEditor::Launch(),
474 InstrumentManager::LaunchInstrumentEditor()
475 - theoretical fix: made SynchronizedConfig follow C++0x memory
476 model more strictly
477 - fixes for using large audio device buffers
478 - Windows: add the installation directory to the DLL search path
479 when loading an editor plugin (solves problems with VST and
480 gigedit on systems with other GTK versions installed)
481
482 * audio driver:
483 - removed the nonsense audio channel constraint (which was hard coded to
484 max. 100 audio channels) for most audio drivers
485 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
486 opposed to the LSCP specs
487 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
488 reflected the wrong value
489 - fixed a memory management bug in ASIO driver
490 - Makefile fix: JACK_CFLAGS wasn't used
491 - JACK: use jack_client_open instead of the deprecated
492 jack_client_new
493 - added (experimental) CoreAudio driver
494 - applied old fixes to the ASIO driver that were included in the
495 previous binary release but accidentally never committed to CVS
496 (fixes #117)
497 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
498 win64)
499 - VST: added support for sample rate and buffer size changes
500 - VST: close editor (Fantasia) when the VST is removed
501 - VST: avoid opening Fantasia more than once for each VST instance
502 - VST: export main function as "main" on Linux too (fix for
503 energyXT)
504 - VST: changed number of output channels from one stereo to 16
505 stereo
506 - added channel routing, fxsends and midi maps to the settings
507 stored in the plugin state
508 - performance optimization of AudioChannel::MixTo() and
509 AudioChannel::CopyTo() methods using GCC vector exensions
510 (if available)
511 - ASIO fixes: avoid initializing the device twice, avoid throwing
512 exception when getting parameters from a disconnected device
513
514 * MIDI driver:
515 - added JACK MIDI driver
516 - dispatch bank select as ordinary CC as well, the user might seriously
517 want to (mis)use it for some purpose ("fixed" in all current MIDI
518 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
519 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
520 CoreMidi or AU
521 - fixed mingw-w64 compilation error in MME driver
522 - made program change handling in MIDI thread real-time safe by
523 moving the logic to a non-RT thread
524 - fixed minor memory leak in ALSA driver
525
526 * instruments database:
527 - avoid time consuming samples scanning when adding instruments
528 to the instruments database
529 - added support for handling lost files in the instruments database
530 - Implemented option for adding instruments in separate directories
531 in the instruments database
532 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
533 - work-around for missing fnmatch function on Windows to make
534 instrument database compilable
535 - added instrument database support on Windows
536 works with both standalone mode and VST plugin.
537 the instruments DB file is located in
538 %USERPROFILE%\.linuxsampler\instruments.db which allows different
539 databases for each windows user
540 if no DB is present it automatically creates the .linuxsampler subdir
541 and then creates an empty DB
542 - fixed recursive import, which was broken on Windows
543
544 * Gigasampler format engine:
545 - fixed a memory leak that could happen when a channel was deleted
546 while notes were playing
547 - made it possible to load an instrument even if the audio thread
548 isn't running
549 - added partial support for the "Controller Triggered" MIDI rule,
550 enough for piano gigs with pedal noise samples
551 - minor fix: only mark FX sends as being modified if really the
552 respective FX send MIDI controller was used
553 - added support for GM global device volume SysEx message
554 (can be selected at compile time to either apply globally to the
555 whole sampler [default] or only to the sampler channels that are
556 connected to the respective MIDI input port the SysEx message arrived
557 on)
558 - bugfix: notes triggered at position 0 in the audio buffer were
559 sometimes wrongly killed in the same buffer, causing no sound to
560 be played
561 - added support for chromatic / drumkit mode Roland GS Sysex message
562 which is usally used to switch a part between chromatic sounds and
563 drumkit sounds (as opposed to their common default setting of MIDI
564 part 10 being a drumkit part and all other ones chromatic parts), in
565 LS however one can switch between the first 16 MIDI instrument maps
566 defined for the sampler
567 - made it possible to create multiple sample channels even if the
568 audio thread isn't running
569 - fixed crash when removing channel with active voices (#116)
570 - bugfix: on sample reference changes (instrument editor), only
571 un-cache the respective sample if it's really not used by any
572 sampler engine anymore
573 - re-cache samples in case they were changed by an instrument editor,
574 e.g. when a sample was added while playing (#82)
575 - fixed hanging notes which occured when note-off event had the exact
576 same time stamp as the voice's note-on event and occured both in the
577 same audio fragment cycle (fixes bug #112)
578 - added support for the "fine tune" and "pitch bend range"
579 instrument-level gig parameters
580 - fixed minor artifacts in pitch bend handling
581 - added support for GS Reset SysEx message
582 - allow gig files to use unlimited downward pitch shifting
583 - added a limit check for upward pitch shifting
584 - bugfix: sometimes, when playing a note twice fast, the second
585 note was silent
586 - fixed crash happening when a pitch bend event arrived at the
587 same time a new instrument was loading
588
589 * LSCP server:
590 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
591 react on MIDI data arriving on certain sampler channels (so far only
592 Note-On and Note-Off events are sent via this LSCP event)
593 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
594 react on MIDI data arriving on certain MIDI input devices (so far only
595 Note-On and Note-Off events are sent via this LSCP event)
596 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
597 SET DB_INSTRUMENT FILE_PATH
598 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
599 frontends to send MIDI messages to specific sampler channel
600 - added two additional fields to GET FILE INSTRUMENT INFO command -
601 KEY_BINDINGS and KEYSWITCH_BINDINGS
602 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
603 was incorrect
604 - Optimized the retrieval of the MIDI instrument mappings
605 - added new LSCP command "SET VOICES" to globally alter the maximum
606 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
607 be triggered respectively
608 - added new LSCP command "SET STREAMS" to globally alter the maximum
609 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
610 which will be triggered respectively
611 - bugfix: retry if "select" returns EINTR (this fixes a crash when
612 a gigedit file dialog is opened)
613 - close all connections when LSCPServer is deleted
614 - hard close of all sockets on exit
615 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
616 driver
617
618 * Bug fixes:
619 - fixed a crash which occurs when removing a sampler channel waiting
620 to start instrument loading after another channel
621 - fixed a crash which occurs when removing a sampler channel with
622 instrument loading in progress (bug #113)
623 - fixed termination caused by uncaught exception when adding MIDI
624 instrument with PERSISTENT load mode
625 - fixed possible iterator invalidations when resetting the sampler
626 - fixed memory leaks when issuing the following LSCP commands:
627 GET AUDIO_OUTPUT_DRIVER INFO
628 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
629 GET MIDI_INPUT_DRIVER INFO
630 GET MIDI_INPUT_DRIVER_PARAMETER INFO
631 - fixed possible compilation error when sqlite is not present
632 - fixed orphaned pointers when setting maximum voices limit (bug #118)
633 - fixed crash when changing the audio output device of a sampler
634 channel with loaded instrument and start playing notes
635 - fixed endless loop in Engine::SuspendAll() (bug #120)
636 - fixed a low-level atomic load function that was broken on 64-bit
637 PowerPC, which probably could cause crashes on that platform
638 - fixed a memory management error which could cause a crash when a
639 plugin was unloaded
640 - bugfix: two private structs had the same name, which could cause
641 problems if the linker chose the wrong constructor
642 - fixed low-level ConditionServer usage bug that caused lockups on
643 Windows
644
645
646 Version 0.5.1 (6 December 2007)
647
648 * packaging changes:
649 - added autoconf checks for pthread library
650 - added autoconf check for pthread bug found on certain NPTL-enabled
651 glibc versions (see Gentoo bug report #194076)
652 - added autoconf checks for MS Windows
653
654 * general changes:
655 - bugfix: the thread used by an editor plugin didn't die when the
656 editor closed
657 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
658 out all the space. operator--() did not apply size_mask after
659 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
660 order to avoid problems with the _NonVolatileReader functions.
661 - bugfix: Stream.h: added a missing divide by BytesPerSample in
662 GetWriteSpace(). Since this function is currently only used in
663 the stream's qsort() compare function, it didn't trigger any
664 bugs.
665 - Resampler.h, Synthesizer.h: cubic interpolation now works in
666 24bit mode too. Faster method to read 24bit words on little
667 endian machines (x86): replaced 3 byte reads + shifts with a 1
668 unaligned 32bit read and shift
669 - experimental support for MS Windows (MIDI input via MME, AUDIO
670 output via ASIO)
671 - made handling of SIGINT signal (Ctrl-C) a bit more robust
672 - support for monitoring the total number of active disk streams
673 (new LSCP commands: GET TOTAL_STREAM_COUNT,
674 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
675
676 * AUDIO driver:
677 - added Windows ASIO low latency audio driver
678
679 * MIDI driver:
680 - added MME Windows MIDI driver
681
682 * LSCP server:
683 - added support for Windows style path / filenames, however with
684 forward slash path separators instead of backslash
685 (i.e. "C:/foo/bar.gig")
686 - allow naughty liblscp to send non-string device parameters within
687 apostrophes as well
688 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
689 "LIST FILE INSTRUMENTS <file>" and
690 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
691 about an arbitrary instrument file on the system where the sampler is
692 running on
693
694 Version 0.5.0 (15 October 2007)
695
696 * packaging changes:
697 - config.h is not going to be installed along with liblinuxsampler's
698 API header files anymore
699 - only the API relevant header (and source) files will be exported to
700 the Doxygen API documentation (explicitly listed in Doxyfile.in)
701 - added completely new XCode project files for Mac OSX which is now
702 capable to execute our autoconf environment, thus no need anymore
703 to maintain the compile time configuration file (osx/version.h) for
704 OSX manually (patch by Toshi Nagata)
705 - fixed buggy boolean --enable-foo / --disable-foo configure script
706 parameters
707 - global.h now only covers global definitions that are needed for the
708 C++ API header files, all implementation internal global definitions
709 are now in global_private.h
710 - atomic.h is not exposed to the C++ API anymore
711 - no need to include config.h anymore for using LS's API header files
712 - fixed warnings in API doc generation
713
714 * general changes:
715 - replaced the old, confusing MIDI program change mechanism by a
716 flexible MIDI instrument mapper which allows to map arbitrary
717 (MIDI bank, MIDI program) pairs with arbitrary
718 (engine type, instrument file, file index) triplets which will be
719 loaded on the respective channel when such MIDI program change
720 messages arrive, beside that, each entry allows to define a life-time
721 strategy for the instrument, so the user can define whether the
722 instrument should i.e. be permanently loaded (to be able to switch
723 quickly among sounds) or i.e. loaded just on demand when the
724 respective program change arrives (to safe RAM space), as well as a
725 global volume factor for each entry, so the user can adjust the volume
726 dynamic of his mapped instrument collection without having to modify
727 the instrument files, also one can manage arbitrary amount of such
728 MIDI instrument maps and assign each sampler channel individually
729 a certain map, so that i.e. separation of normal instruments and
730 drumkits is possible
731 - new notification events for tracking changes to audio/MIDI devices,
732 MIDI instrument maps, MIDI instruments, FX sends, global volume.
733 - sampler was limited to load max. 200 instruments in the background
734 due to a constant size RingBuffer FIFO which is now replaced by a
735 dynamic (unlimited) size std::list FIFO
736 - added FX sends, these allow to route audio signals to arbitrary audio
737 output channels for being processed by external effect processors
738 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
739 controllers
740 - global (sampler wide) volume can now be controlled at runtime
741 - Implemented new, improved notification system
742 - fixed compilation errors regarding OSX
743 (patch by Toshi Nagata)
744 - implemented instruments database
745 - added support for escape sequences to the instruments database
746 - added highly experimental support for on-the-fly instrument editing
747 within the sampler's process (by using instrument editor plugins),
748 you'll notice the new "Registered instrument editors:" message on
749 startup, added a new LSCP command:
750 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
751 to spawn a matching instrument editor for the instrument on the
752 given sampler channel, the plugin path can be overridden at compile
753 time with ./configure --enable-plugin-dir=/some/dir
754 - added experimental code for synchronizing instrument editors hosted
755 in the sampler's process to safely edit instruments while playing
756 without a crash (hopefully) by either suspending single regions
757 wherever possible or if unavoidable whole engine(s)
758 - fixed several issues in fundamental "Thread" class: set scheduling
759 policy and priority on thread level, set a minimum stack size for
760 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
761 threads simply inherited properties of starting thread instead of
762 setting their own policy and priority
763 - minor fix in our automatic stack trace mechanism on crashes, the
764 main process did not wait for the stack trace process to finish
765 its output
766 - fixed some minor memory leaks
767 - reenabled assembly features support, at the moment only for
768 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
769 - minor assembly fix in x86 features detection (don't use the PIC
770 register, to avoid relocations in the text segment at runtime)
771 - POSIX callback functions of Thread.h are hidden
772
773 * MIDI driver:
774 - dispatch bank select (MSB and LSB) messages
775
776 * audio driver:
777 - the ALSA audio output driver parameters now reflect the correct
778 parameter value ranges for the respective selected sound card
779 (patch by Till Wimmer, a bit fixed and extended)
780
781 * Gigasampler format engine:
782 - if a filter is used and EG2 finishes before EG1, let the voice
783 die when EG2 has finished (this fixes a problem with clicks and
784 voice starvation for some gigs)
785 - playback is no longer disabled during instrument loading
786 - all notes playing on a channel that changes its instrument keep
787 playing with the old instrument until they get a note off
788 command
789 - EG fix: a release value of zero could cause noises or crash
790 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
791 - EG fine tuning: when attack is zero the EG starts at a level
792 above max sustain level, which means that there is a decay phase
793 even if sustain is 100%
794 - more EG fixes: the level could sometimes go below zero and cause
795 noises or crashes
796 - minor fix of EGDecay (patch by Toshi Nagata)
797 - fixed compiler error when --enable-override-filter-type was
798 supplied to the configure script (fixes #46)
799 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
800 instead of a fix value
801 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
802 127 (solo mode) only kill voices if the respective mode really
803 changed
804
805 * LSCP server:
806 - fixed compile time error for old Bison versions
807 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
808 - parser now supports extended ASCII character set
809 (up to ASCII code 255, i.e. includes now umlauts and accents)
810 - filename arguments in LSCP commands now allow to use escape
811 sequences, that is directly literal as one of: \', \", \\, \n, \r,
812 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
813 code value like \xf2) (fixes bug #24)
814 - the following LSCP commands now also support escape sequences for at
815 least one of their text-based parameters (i.e. name, description):
816 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
817 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
818 "SET DB_INSTRUMENT_DIRECTORY NAME",
819 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
820 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
821 "FIND DB_INSTRUMENT_DIRECTORIES"
822 - returns verbose syntax errors (line and column where syntax error
823 occured, the unexpected character and the actually expected, possible
824 character(s), the latter only if less than 5 possibilities)
825 - made sure that LSCP syntax is not affected by gigedit locale
826 settings
827 - bugfix regarding strings parameter lists: all comma separated lists
828 of strings were treated as being one string containing commas
829 (fixes #57)
830
831 * Bug fixes:
832 - fixed crash occurring on certain LSCP scripts (Bug 39)
833 - another thread safety fix for lscp "load engine" and "set
834 channel audio output device"
835 - fixed a crash which occurs when reassigning the same engine
836 on a sampler channel with connected MIDI device
837 - fixed a crash which occurs when changing the number of ports of a MIDI
838 device connected to a sampler channel to number less then or equal
839 to the index of the port to which the sampler channel is connected.
840 - The previous bindings were not been disconnected when altering
841 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
842 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
843 - The active stream/voice count statistic was incorrect.
844 - notification events were not been sent for some sampler
845 channel changes
846 - added default min and max values to restrict the number of allowed
847 audio output channels and MIDI input ports
848 - the connection to the PCM interface is now closed when destroying
849 an audio output device
850 - files with slash in their path or filename could not be loaded
851
852 * test cases:
853 - updated and fixed (haven't been touched in a while)
854
855 Version 0.4.0 (24 November 2006)
856
857 * packaging changes:
858 - changed deprecated copyright attribute to license; added ldconfig
859 to post-(un)install steps; added devel package for liblinuxsampler;
860 to linuxsampler.spec (RPM)
861 - install necessary development header files for allowing 3rd party
862 applications to link against liblinuxsampler
863 - liblinuxsampler's API documentation can be generated with 'make docs'
864 (Doxygen required)
865 - added benchmark to automatically detect the best triangle LFO
866 implementation (currently either an integer math solution or a
867 di-harmonic approximation), automatic detection can be overriden
868 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
869 configure script argument though (mandatory for cross-compilation)
870 - do not automatically pick optimized gcc flags if the user already
871 provided some on his own (as CXXFLAGS)
872 - added compile time option to disable processing of All-Notes-Off MIDI
873 messages
874 - added compile time options to allow disabling the various audio and
875 MIDI drivers
876 - fixed automatic GCC CPU switch detection on PPC
877 (patch by Ebrahim Mayat)
878
879 * Gigasampler format engine:
880 - extensive synthesis optimization
881 (reimplementation of EGs and LFO(s), removed synthesis parameter
882 prerendering and the synthesis parameter matrix in general, splitting
883 each audio fragment into subfragments now where each subfragment uses
884 constant pitch and filter coefficients. The volume coefficient is
885 linearly interpolated inside a subfragment, unless
886 --disable-interpolate-volume is set.)
887 - fine tuning of the EG modulation parameters
888 - improved filter cutoff calculation by adding support for the
889 following gig parameters: Cutoff freq (used when no cutoff
890 controller is defined), Control invert, Minimum cutoff, Velocity
891 curve and Velocity range. The keyboard tracking now scales
892 cutoff frequency instead of resonance.
893 - added support for gig parameter Resonance.
894 - fixed bug in sysex handling (patch by Juan Linietsky)
895 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
896 which can be overridden with --enable-global-attenuation
897 - EG fixes: made the length of "attack hold" stage more
898 accurate. Release stage can now start before attack stage
899 ends. Cancel release didn't work when sustain was zero. Attack
900 time now has a minimal value to prevent clicks.
901 - fixed pitch changes larger than one octave
902 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
903 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
904 all modes can be altered via standard GM messages, that is CC5 for
905 altering portamento time, CC65 for enabling / disabling portamento
906 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
907 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
908 parameter) and crossfade
909 - added support for the "attenuation controller threshold" gig
910 parameter
911 - added smoothing of volume changes caused by control change
912 messages
913 - sample loop parameters are now taken from the DimensionRegion
914 instead of the wave chunk
915 - fixed keyswitching for v3 gigs with a number of keyswitch splits
916 not equal to a power of two
917 - reimplementation of the filter algorithm. The new filter is more
918 accurate and supports all gig filter types, including bandreject
919 and lowpass turbo.
920 - real support for 24 bit samples - samples are not truncated to
921 16 bits anymore
922 - support for aftertouch (channel pressure, not polyphonic
923 aftertouch)
924 - LFO1 behaviour fixed (dampening from max volume instead of
925 amplifying from 0)
926
927 * LSCP server:
928 - fixed application exit on broken pipe error (fixes bug #20)
929 - fixed the notification messages delay due to lack of
930 network activity (fixes bug #26)
931 - fixed parser bug which occured on space(s) within device parameters
932 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
933
934 * audio driver:
935 - added aRts audio output driver (by no means RT safe)
936
937 * MIDI driver:
938 - fixed legacy sysex code which caused dispatching of MIDI SysEx
939 messages several times instead of once
940 - API extension for MIDI drivers which already supply exact time stamps
941 for events (i.e. for offline rendering based MIDI drivers)
942 - added checks for bad MIDI data
943
944 * linuxsampler application:
945 - show available sampler engine types on startup
946
947 * general changes:
948 - support for muting sampler channels and solo mode of the same, two new
949 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
950 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
951 introduced for this, the behavior is the same like on a mixer console
952 (patch by Grigor Iliev, a bit adjusted). Also added configure option
953 --enable-process-muted-channels which can be used to enable the
954 processing of muted channels.
955 - support for sostenuto pedal
956 - support for monitoring the total number of active voices
957 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
958 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
959 - fixed some memory management errors
960 - fixed some concurrency problems that could lead to crashes when
961 LSCP commands were executed
962 - fixed crash when instrument loading failed previously on the same
963 sampler channel (fixes bug #36)
964
965 Version 0.3.3 (15 July 2005)
966
967 * packaging changes:
968 - fixed compilation with gcc 4.0
969
970 * Gigasampler format engine:
971 - LFO preprocessing was performed even though the respective LFO was
972 disabled by the instrument patch (minor efficiency fix)
973 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
974 for volume ramp downs in the same fragment (needed for current voice
975 stealing implementation) then simply inform the user with a warning
976 about possible click sounds and reduce the volume ramp down
977 appropriately instead of cancelling the audio device connection
978
979 Version 0.3.2 (24 June 2005)
980
981 * packaging changes:
982 - updated autotools build files to compile on OS X
983 (conditional compilation of CoreMIDI and MidiShare drivers)
984 - hand-crafted assembly optimization code can be disabled with
985 './configure --disable-asm' (definitely not recommended)
986 - fixed 'make dist' rule to include all necessary files
987 - require automake (>= 1.5) for 'make -f Makefile.cvs'
988 (due to 'dist-bzip2' automake option)
989
990 * Gigasampler format engine:
991 - support for the gig parameters for "release velocity response" curves
992 - fine tuning of the EGADSR envelope
993 - volume of release triggered samples now depends on note-on velocity,
994 note length and gig parameter "release trigger decay" instead of
995 note-off velocity.
996 - revised voice stealing
997 (fixes crash and endless loop caused by voice stealing)
998 - don't reset scale tuning on instrument or audio output device change
999 - handle key group conflicts right at the beginning of each fragment
1000 instead of when the respective voice is actually launched
1001 (fixes undefined behavior if stolen voices belonged to a key group -
1002 this case was followed by a "killed voice survived" error message)
1003 - fixed minor issue with null/silence samples
1004 (those stole voices even though they don't need a voice at all which
1005 resulted in "voice stealing didn't work out" messages)
1006 - don't reset volume, pan, pitch and MIDI controller values on
1007 instrument or audio output device change
1008
1009 * LSCP server:
1010 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1011 - fixed LSCP event "CHANNEL_INFO" notification
1012 (e.g. did not notify on volume changes or MIDI program change events)
1013
1014 * linuxsampler application:
1015 - added command line parameters --lscp-addr and --lscp-port to override
1016 default IP address and port of LSCP server
1017
1018 Version 0.3.1 (24 May 2005)
1019
1020 * initial release
