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

267 - Listen to all interfaces on Mac OS X (INADDR_ANY)
268 - VST bugfix: If the host called resume() before and after
269 changing sample rate or block size, the number of channels was
270 incorrectly set to two. This caused silence in Cubase 5.

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

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