31 - fix for building with bison 3.0 (#202)
32
33 * general changes:
34 - Refactoring: moved the independent code from
35 the Gigasampler format engine to base classes
36 - command line option '--profile' is currently disabled, since the
37 respective profiling code is currently broken
38 - Introduced support for optional environment variable
39 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
40 where the sampler shall look for instrument editor plugins
41 (patch by Luis Garrido, slightly modified).
42 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
43 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
44 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
45 note (in this implementation of the sampler its simply hard routed to
46 the 1st effect send of the sampler channel, no matter what the actual
47 effect type is)
48 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
49 note (in this implementation of the sampler its simply hard routed to
50 the 2nd effect send of the sampler channel, no matter what the actual
51 effect type is)
52 - implemented support for internal LADSPA effects
53 - raised limit of program change queue from 100 to 512
54 (as suggested by Alex Stone)
55 - implemented sine LFO, pulse LFO and saw LFO
56 - experimental support for per voice equalization
57 - added command line option --exec-after-init
58 - Introduced new C++ API method:
59 EngineChannel::InstrumentFileName(int index)
60 allowing to retrieve the whole list of files used for the loaded
61 instrument on an engine channel (a.k.a. part). Some GigaStudio
62 instruments for example are splitted over several files like
63 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
64 - Added new C++ API method Sampler::GetGlobalMaxVoices().
65 - Added new C++ API method Sampler::GetGlobalMaxStreams().
66 - Added new C++ API method Sampler::SetGlobalMaxVoices().
67 - Added new C++ API method Sampler::SetGlobalMaxStreams().
68 - Various "const" and "restrict" optimizations.
69 - all engines: add pan CC value to instrument pan parameter before
70 applying panning, instead of using two separate pan functions in
71 series (#182)
72 - added a lock guard class for exception safe mutex handling and
73 used it everywhere appropriate
74 - Immediately apply scale tuning changes to active voices.
75 - Exposed scale tuning to C++ API (along to the already existing standard
76 SysEx way).
77 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
78 and broken for ppc64. (Seq_cst loads and stores are actually not
79 used in LS, so the bug wasn't noticable.)
80 - lsatomic.h: added ARMv7 support
81
82 * Gigasampler format engine:
83 - implemented the "round robin keyboard" dimension
84 - fixed round robin and random dimensions for cases when number of
85 dimension zones is not a power of two
86 - made round robin use a counter for each region instead of each
87 key
88 - bugfix: pitch LFO controller "internal+aftertouch" was broken
89 - bugfix: filter keyboard tracking was broken
90 - filter performance fix (an unnecessary copy was made of the
91 filter parameters in each sub fragment)
92 - handle special case when pan parameter in gig file has max or
93 min value
94 - Exclusive Groups: don't ever stop voices of the same note,
95 doesn't sound naturally with a drumkit
96 - fixed EG1 modulation when attack or release is zero
97
98 * SFZ format engine:
99 - Initial implementation (not usable yet)
100 - added support for v2 multiple stage envelope generators
101 - added a fine-tuned v1 envelope generator instead of using the
102 one from the gig engine

269 - VST bugfix: If the host called resume() before and after
270 changing sample rate or block size, the number of channels was
271 incorrectly set to two. This caused silence in Cubase 5.

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

910 - sample loop parameters are now taken from the DimensionRegion
911 instead of the wave chunk
912 - fixed keyswitching for v3 gigs with a number of keyswitch splits
913 not equal to a power of two
914 - reimplementation of the filter algorithm. The new filter is more
915 accurate and supports all gig filter types, including bandreject
916 and lowpass turbo.
917 - real support for 24 bit samples - samples are not truncated to
918 16 bits anymore
919 - support for aftertouch (channel pressure, not polyphonic
920 aftertouch)
921 - LFO1 behaviour fixed (dampening from max volume instead of
922 amplifying from 0)
923
924 * LSCP server:
925 - fixed application exit on broken pipe error (fixes bug #20)
926 - fixed the notification messages delay due to lack of
927 network activity (fixes bug #26)
928 - fixed parser bug which occured on space(s) within device parameters
929 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
930
931 * audio driver:
932 - added aRts audio output driver (by no means RT safe)
933
934 * MIDI driver:
935 - fixed legacy sysex code which caused dispatching of MIDI SysEx
936 messages several times instead of once
937 - API extension for MIDI drivers which already supply exact time stamps
938 for events (i.e. for offline rendering based MIDI drivers)
939 - added checks for bad MIDI data
940
941 * linuxsampler application:
942 - show available sampler engine types on startup
943
944 * general changes:
945 - support for muting sampler channels and solo mode of the same, two new
946 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
947 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
948 introduced for this, the behavior is the same like on a mixer console
949 (patch by Grigor Iliev, a bit adjusted). Also added configure option
950 --enable-process-muted-channels which can be used to enable the
951 processing of muted channels.
952 - support for sostenuto pedal
953 - support for monitoring the total number of active voices
954 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
955 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
956 - fixed some memory management errors
957 - fixed some concurrency problems that could lead to crashes when
958 LSCP commands were executed
959 - fixed crash when instrument loading failed previously on the same
960 sampler channel (fixes bug #36)
961
962 Version 0.3.3 (15 July 2005)
963
964 * packaging changes:
965 - fixed compilation with gcc 4.0
966
967 * Gigasampler format engine:
968 - LFO preprocessing was performed even though the respective LFO was
969 disabled by the instrument patch (minor efficiency fix)
970 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
971 for volume ramp downs in the same fragment (needed for current voice
972 stealing implementation) then simply inform the user with a warning
973 about possible click sounds and reduce the volume ramp down
974 appropriately instead of cancelling the audio device connection
975
976 Version 0.3.2 (24 June 2005)
977
978 * packaging changes:
979 - updated autotools build files to compile on OS X
980 (conditional compilation of CoreMIDI and MidiShare drivers)
981 - hand-crafted assembly optimization code can be disabled with
982 './configure --disable-asm' (definitely not recommended)
983 - fixed 'make dist' rule to include all necessary files
984 - require automake (>= 1.5) for 'make -f Makefile.cvs'
985 (due to 'dist-bzip2' automake option)
986
987 * Gigasampler format engine:
988 - support for the gig parameters for "release velocity response" curves
989 - fine tuning of the EGADSR envelope
990 - volume of release triggered samples now depends on note-on velocity,
991 note length and gig parameter "release trigger decay" instead of
992 note-off velocity.
993 - revised voice stealing
994 (fixes crash and endless loop caused by voice stealing)
995 - don't reset scale tuning on instrument or audio output device change
996 - handle key group conflicts right at the beginning of each fragment
997 instead of when the respective voice is actually launched
998 (fixes undefined behavior if stolen voices belonged to a key group -
999 this case was followed by a "killed voice survived" error message)
1000 - fixed minor issue with null/silence samples
1001 (those stole voices even though they don't need a voice at all which
1002 resulted in "voice stealing didn't work out" messages)
1003 - don't reset volume, pan, pitch and MIDI controller values on
1004 instrument or audio output device change
1005
1006 * LSCP server:
1007 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1008 - fixed LSCP event "CHANNEL_INFO" notification
1009 (e.g. did not notify on volume changes or MIDI program change events)
1010
1011 * linuxsampler application:
1012 - added command line parameters --lscp-addr and --lscp-port to override
1013 default IP address and port of LSCP server
1014
1015 Version 0.3.1 (24 May 2005)
1016
1017 * initial release
