38 * general changes:
39 - Refactoring: moved the independent code from
40 the Gigasampler format engine to base classes
41 - command line option '--profile' is currently disabled, since the
42 respective profiling code is currently broken
43 - Introduced support for optional environment variable
44 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
45 where the sampler shall look for instrument editor plugins
46 (patch by Luis Garrido, slightly modified).
47 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
48 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
49 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
50 note (in this implementation of the sampler its simply hard routed to
51 the 1st effect send of the sampler channel, no matter what the actual
52 effect type is)
53 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
54 note (in this implementation of the sampler its simply hard routed to
55 the 2nd effect send of the sampler channel, no matter what the actual
56 effect type is)
57 - implemented support for internal LADSPA effects
58 - raised limit of program change queue from 100 to 512
59 (as suggested by Alex Stone)
60 - implemented sine LFO, pulse LFO and saw LFO
61 - experimental support for per voice equalization
62 - added command line option --exec-after-init
63 - Introduced new C++ API method:
64 EngineChannel::InstrumentFileName(int index)
65 allowing to retrieve the whole list of files used for the loaded
66 instrument on an engine channel (a.k.a. part). Some GigaStudio
67 instruments for example are splitted over several files like
68 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
69 - Added new C++ API method Sampler::GetGlobalMaxVoices().
70 - Added new C++ API method Sampler::GetGlobalMaxStreams().
71 - Added new C++ API method Sampler::SetGlobalMaxVoices().
72 - Added new C++ API method Sampler::SetGlobalMaxStreams().
73 - Various "const" and "restrict" optimizations.
74 - all engines: add pan CC value to instrument pan parameter before
75 applying panning, instead of using two separate pan functions in
76 series (#182)
77 - added a lock guard class for exception safe mutex handling and
78 used it everywhere appropriate
79 - Immediately apply scale tuning changes to active voices.
80 - Exposed scale tuning to C++ API (along to the already existing standard
81 SysEx way).
82 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
83 and broken for ppc64. (Seq_cst loads and stores are actually not
84 used in LS, so the bug wasn't noticable.)
85 - lsatomic.h: added ARMv7 support
86 - Added support for multiple MIDI input ports per sampler channel (and
87 added various new C++ methods for this new feature / design change, old
88 C++ API methods for managing SamplerChannel's MIDI inputs are now marked
89 as deprecated but are still there and should provide full behavior
90 backward compatibility).
91 - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
92 unsafe and caused compilation error with clang 2.x).
93 - Bugfix: only process the latest MIDI program change event.
94 - Introducing the LSCP shell, which provides convenient control of the
95 sampler from the command line by providing LSCP aware features.
96
97 * Gigasampler format engine:
98 - implemented the "round robin keyboard" dimension
99 - fixed round robin and random dimensions for cases when number of
100 dimension zones is not a power of two
101 - made round robin use a counter for each region instead of each
102 key
103 - bugfix: pitch LFO controller "internal+aftertouch" was broken
104 - bugfix: filter keyboard tracking was broken
105 - filter performance fix (an unnecessary copy was made of the
106 filter parameters in each sub fragment)
107 - handle special case when pan parameter in gig file has max or
108 min value
109 - Exclusive Groups: don't ever stop voices of the same note,
110 doesn't sound naturally with a drumkit
111 - fixed EG1 modulation when attack or release is zero
112
113 * SFZ format engine:
114 - Initial implementation (not usable yet)

411 - Windows: disabled the previous thread fix on non-Mac systems, as
412 it caused hanging threads on Windows
413 - Fixed possible crashes due to corrupted MIDI/audio device list
414 after MIDI/audio device creation failure
415 - When creating MIDI instrument map entries with "PERSISTENT" type, the
416 instruments were uselessly precached with zero samples, however it still
417 took the full preloading time and on 1st program change the respective
418 instrument was completely reloaded again.
419 - fixed handling of rapid bank select and program change messages
420 sent to the same sampler channel (patch from the Open Octave
421 project, slightly adjusted)
422 - fixed crash when trying to create an effect instance with controls
423 which min and/or max values depend on the sample rate
424 - fixed bug #162
425 - bugfix: LADSPA_PATH was not evaluated correctly when containing
426 multiple paths (#165)
427 - thread safety fixes for the instrument loading thread
428 - bugfix: instrument loading crashed for sfz and sf2 in Ardour
429 (#176)
430 - more thread safety fixes for the instrument loading thread
431 - sfz/sf2 engine: fixed crash when using small audio fragment size
432 - Mac OS X: fixed crash when unloading plugin on 10.7 and later
433 - Mac OS X: fixed process hang when unloading 32-bit plugin (bug
434 introduced in previous fix)
435 - fixed crash when a channel received a program change while
436 playing a note in a key group
437 - fixed erroneous error message piping in VoiceBase.h
438 (labelled "Disk stream not available in time")
439 - Update effects on sample rate & period size changes (to avoid
440 crashes and noise on such transitions).
441 - ignore missing LADSPA paths without ignoring valid LADSPA paths
442 (fixes #208)
443
444 Version 1.0.0 (31 July 2009)
445
446 * packaging changes:
447 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
448 causing e.g. the libgig test to fail when
449 "./configure --disable-jack-driver" was used
450 (patch by Alexis Ballier)
451 - fixed compilation with gcc 4.3
452 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
453 - fixed configure so it detects x86_64 (#107)
454 - fixes for building with newer MinGW versions
455 - fix for building with bison 2.4 (#111)
456 - fixed building with libgig installed in a non-standard directory
457 - minor fix in configure for mmsystem.h detection on MinGW
458 - Windows: look for editor plugins and Fantasia using base
459 directory of liblinuxsampler dll (look in the same directory and one
460 directory above)
461 - configure script fix: removed unconditional use of SSE
462 - fixed building with sqlite installed in a non-standard directory
463 - when cross-compiling, don't try to create instruments.db
464 - fix for new mingw-w64 version, which has usleep
465
466 * general changes:
467 - bugfix: on some POSIX systems instrument editor plugins refused to
468 load as we used a non-portable Linux specific struct field
469 (fixes bug #70, patch by Ronald Baljeu)
470 - fixed endless loop which occured when loading an instrument editor
471 plugin DLL on Windows systems failed
472 - fixed memory leaks that occurred when liblinuxsampler was unloaded
473 - optimized the SynchronizedConfig class so it doesn't wait
474 unnecessarily long after an update
475 - added support for notifying instrument editors on note-on / note-off
476 events (e.g. to highlight the pressed keys on the virtual keyboard
477 of gigedit)
478 - added support for triggering notes by instrument editors (see above)
479 - be verbose on DLL load errors (on Linux)
480 - fixed di-harmonic triangle LFO implementation (this LFO implementation
481 is only used by very few systems, most pick the int math
482 implementation, which is usually faster)
483 - fixes for audio drivers with varying buffer sizes
484 - experimental support for running LinuxSampler as a DSSI, LV2 and
485 VST plugin
486 - notification events for stream/voice count statistics are now sent
487 only when there are actual changes
488 - added memory ordering constraints to improve stability on
489 multi-core and multi-cpu systems
490 - maximum voices and disk streams can now be altered at runtime
491 - fixed CPU feature detection on x86_64 (maybe fixes #108)
492 - automatic stacktrace mechanism is now turned off by default and can
493 be switched on by command line option "--stacktrace" (the automatic
494 stacktrace mechanism seems to be broken on most systems at the moment)
495 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
496 a pointer to the launched InstrumentEditor object
497 - added optional 3rd party user data parameter for following
498 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
499 InstrumentEditor::Launch(),
500 InstrumentManager::LaunchInstrumentEditor()
501 - theoretical fix: made SynchronizedConfig follow C++0x memory
502 model more strictly
503 - fixes for using large audio device buffers
504 - Windows: add the installation directory to the DLL search path
505 when loading an editor plugin (solves problems with VST and
506 gigedit on systems with other GTK versions installed)
507 - updated linuxsampler man page
508
509 * audio driver:
510 - removed the nonsense audio channel constraint (which was hard coded to
511 max. 100 audio channels) for most audio drivers
512 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
513 opposed to the LSCP specs
514 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
515 reflected the wrong value
516 - fixed a memory management bug in ASIO driver
517 - Makefile fix: JACK_CFLAGS wasn't used
518 - JACK: use jack_client_open instead of the deprecated
519 jack_client_new
520 - added (experimental) CoreAudio driver
521 - applied old fixes to the ASIO driver that were included in the
522 previous binary release but accidentally never committed to CVS
523 (fixes #117)
524 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
525 win64)
526 - VST: added support for sample rate and buffer size changes
527 - VST: close editor (Fantasia) when the VST is removed
528 - VST: avoid opening Fantasia more than once for each VST instance
529 - VST: export main function as "main" on Linux too (fix for
530 energyXT)
531 - VST: changed number of output channels from one stereo to 16
532 stereo
533 - added channel routing, fxsends and midi maps to the settings
534 stored in the plugin state
535 - performance optimization of AudioChannel::MixTo() and
536 AudioChannel::CopyTo() methods using GCC vector exensions
537 (if available)
538 - ASIO fixes: avoid initializing the device twice, avoid throwing
539 exception when getting parameters from a disconnected device
540
541 * MIDI driver:
542 - added JACK MIDI driver
543 - dispatch bank select as ordinary CC as well, the user might seriously
544 want to (mis)use it for some purpose ("fixed" in all current MIDI
545 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
546 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
547 CoreMidi or AU
548 - fixed mingw-w64 compilation error in MME driver
549 - made program change handling in MIDI thread real-time safe by
550 moving the logic to a non-RT thread
551 - fixed minor memory leak in ALSA driver
552
553 * instruments database:
554 - avoid time consuming samples scanning when adding instruments
555 to the instruments database
556 - added support for handling lost files in the instruments database
557 - Implemented option for adding instruments in separate directories
558 in the instruments database
559 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
560 - work-around for missing fnmatch function on Windows to make
561 instrument database compilable
562 - added instrument database support on Windows
563 works with both standalone mode and VST plugin.
564 the instruments DB file is located in
565 %USERPROFILE%\.linuxsampler\instruments.db which allows different
566 databases for each windows user
567 if no DB is present it automatically creates the .linuxsampler subdir
568 and then creates an empty DB
569 - fixed recursive import, which was broken on Windows
570
571 * Gigasampler format engine:
572 - fixed a memory leak that could happen when a channel was deleted
573 while notes were playing
574 - made it possible to load an instrument even if the audio thread
575 isn't running
576 - added partial support for the "Controller Triggered" MIDI rule,
577 enough for piano gigs with pedal noise samples
578 - minor fix: only mark FX sends as being modified if really the
579 respective FX send MIDI controller was used
580 - added support for GM global device volume SysEx message
581 (can be selected at compile time to either apply globally to the
582 whole sampler [default] or only to the sampler channels that are
583 connected to the respective MIDI input port the SysEx message arrived
584 on)
585 - bugfix: notes triggered at position 0 in the audio buffer were
586 sometimes wrongly killed in the same buffer, causing no sound to
587 be played
588 - added support for chromatic / drumkit mode Roland GS Sysex message
589 which is usally used to switch a part between chromatic sounds and
590 drumkit sounds (as opposed to their common default setting of MIDI
591 part 10 being a drumkit part and all other ones chromatic parts), in
592 LS however one can switch between the first 16 MIDI instrument maps
593 defined for the sampler
594 - made it possible to create multiple sample channels even if the
595 audio thread isn't running
596 - fixed crash when removing channel with active voices (#116)
597 - bugfix: on sample reference changes (instrument editor), only
598 un-cache the respective sample if it's really not used by any
599 sampler engine anymore
600 - re-cache samples in case they were changed by an instrument editor,
601 e.g. when a sample was added while playing (#82)
602 - fixed hanging notes which occured when note-off event had the exact
603 same time stamp as the voice's note-on event and occured both in the
604 same audio fragment cycle (fixes bug #112)
605 - added support for the "fine tune" and "pitch bend range"
606 instrument-level gig parameters
607 - fixed minor artifacts in pitch bend handling
608 - added support for GS Reset SysEx message
609 - allow gig files to use unlimited downward pitch shifting
610 - added a limit check for upward pitch shifting
611 - bugfix: sometimes, when playing a note twice fast, the second
612 note was silent
613 - fixed crash happening when a pitch bend event arrived at the
614 same time a new instrument was loading
615
616 * LSCP server:
617 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
618 react on MIDI data arriving on certain sampler channels (so far only
619 Note-On and Note-Off events are sent via this LSCP event)
620 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
621 react on MIDI data arriving on certain MIDI input devices (so far only
622 Note-On and Note-Off events are sent via this LSCP event)
623 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
624 SET DB_INSTRUMENT FILE_PATH
625 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
626 frontends to send MIDI messages to specific sampler channel
627 - added two additional fields to GET FILE INSTRUMENT INFO command -
628 KEY_BINDINGS and KEYSWITCH_BINDINGS
629 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
630 was incorrect
631 - Optimized the retrieval of the MIDI instrument mappings
632 - added new LSCP command "SET VOICES" to globally alter the maximum
633 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
634 be triggered respectively
635 - added new LSCP command "SET STREAMS" to globally alter the maximum
636 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
637 which will be triggered respectively
638 - bugfix: retry if "select" returns EINTR (this fixes a crash when
639 a gigedit file dialog is opened)
640 - close all connections when LSCPServer is deleted
641 - hard close of all sockets on exit
642 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
643 driver
644
645 * Bug fixes:
646 - fixed a crash which occurs when removing a sampler channel waiting
647 to start instrument loading after another channel
648 - fixed a crash which occurs when removing a sampler channel with
649 instrument loading in progress (bug #113)
650 - fixed termination caused by uncaught exception when adding MIDI
651 instrument with PERSISTENT load mode
652 - fixed possible iterator invalidations when resetting the sampler
653 - fixed memory leaks when issuing the following LSCP commands:
654 GET AUDIO_OUTPUT_DRIVER INFO
655 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
656 GET MIDI_INPUT_DRIVER INFO
657 GET MIDI_INPUT_DRIVER_PARAMETER INFO
658 - fixed possible compilation error when sqlite is not present
659 - fixed orphaned pointers when setting maximum voices limit (bug #118)
660 - fixed crash when changing the audio output device of a sampler
661 channel with loaded instrument and start playing notes
662 - fixed endless loop in Engine::SuspendAll() (bug #120)
663 - fixed a low-level atomic load function that was broken on 64-bit
664 PowerPC, which probably could cause crashes on that platform
665 - fixed a memory management error which could cause a crash when a
666 plugin was unloaded
667 - bugfix: two private structs had the same name, which could cause
668 problems if the linker chose the wrong constructor
669 - fixed low-level ConditionServer usage bug that caused lockups on
670 Windows
671
672
673 Version 0.5.1 (6 December 2007)
674
675 * packaging changes:
676 - added autoconf checks for pthread library
677 - added autoconf check for pthread bug found on certain NPTL-enabled
678 glibc versions (see Gentoo bug report #194076)
679 - added autoconf checks for MS Windows
680
681 * general changes:
682 - bugfix: the thread used by an editor plugin didn't die when the
683 editor closed
684 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
685 out all the space. operator--() did not apply size_mask after
686 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
687 order to avoid problems with the _NonVolatileReader functions.
688 - bugfix: Stream.h: added a missing divide by BytesPerSample in
689 GetWriteSpace(). Since this function is currently only used in
690 the stream's qsort() compare function, it didn't trigger any
691 bugs.
692 - Resampler.h, Synthesizer.h: cubic interpolation now works in
693 24bit mode too. Faster method to read 24bit words on little
694 endian machines (x86): replaced 3 byte reads + shifts with a 1
695 unaligned 32bit read and shift
696 - experimental support for MS Windows (MIDI input via MME, AUDIO
697 output via ASIO)
698 - made handling of SIGINT signal (Ctrl-C) a bit more robust
699 - support for monitoring the total number of active disk streams
700 (new LSCP commands: GET TOTAL_STREAM_COUNT,
701 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
702
703 * AUDIO driver:
704 - added Windows ASIO low latency audio driver
705
706 * MIDI driver:
707 - added MME Windows MIDI driver
708
709 * LSCP server:
710 - added support for Windows style path / filenames, however with
711 forward slash path separators instead of backslash
712 (i.e. "C:/foo/bar.gig")
713 - allow naughty liblscp to send non-string device parameters within
714 apostrophes as well
715 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
716 "LIST FILE INSTRUMENTS <file>" and
717 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
718 about an arbitrary instrument file on the system where the sampler is
719 running on
720
721 Version 0.5.0 (15 October 2007)
722
723 * packaging changes:
724 - config.h is not going to be installed along with liblinuxsampler's
725 API header files anymore
726 - only the API relevant header (and source) files will be exported to
727 the Doxygen API documentation (explicitly listed in Doxyfile.in)
728 - added completely new XCode project files for Mac OSX which is now
729 capable to execute our autoconf environment, thus no need anymore
730 to maintain the compile time configuration file (osx/version.h) for
731 OSX manually (patch by Toshi Nagata)
732 - fixed buggy boolean --enable-foo / --disable-foo configure script
733 parameters
734 - global.h now only covers global definitions that are needed for the
735 C++ API header files, all implementation internal global definitions
736 are now in global_private.h
737 - atomic.h is not exposed to the C++ API anymore
738 - no need to include config.h anymore for using LS's API header files
739 - fixed warnings in API doc generation
740
741 * general changes:
742 - replaced the old, confusing MIDI program change mechanism by a
743 flexible MIDI instrument mapper which allows to map arbitrary
744 (MIDI bank, MIDI program) pairs with arbitrary
745 (engine type, instrument file, file index) triplets which will be
746 loaded on the respective channel when such MIDI program change
747 messages arrive, beside that, each entry allows to define a life-time
748 strategy for the instrument, so the user can define whether the
749 instrument should i.e. be permanently loaded (to be able to switch
750 quickly among sounds) or i.e. loaded just on demand when the
751 respective program change arrives (to safe RAM space), as well as a
752 global volume factor for each entry, so the user can adjust the volume
753 dynamic of his mapped instrument collection without having to modify
754 the instrument files, also one can manage arbitrary amount of such
755 MIDI instrument maps and assign each sampler channel individually
756 a certain map, so that i.e. separation of normal instruments and
757 drumkits is possible
758 - new notification events for tracking changes to audio/MIDI devices,
759 MIDI instrument maps, MIDI instruments, FX sends, global volume.
760 - sampler was limited to load max. 200 instruments in the background
761 due to a constant size RingBuffer FIFO which is now replaced by a
762 dynamic (unlimited) size std::list FIFO
763 - added FX sends, these allow to route audio signals to arbitrary audio
764 output channels for being processed by external effect processors
765 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
766 controllers
767 - global (sampler wide) volume can now be controlled at runtime
768 - Implemented new, improved notification system
769 - fixed compilation errors regarding OSX
770 (patch by Toshi Nagata)
771 - implemented instruments database
772 - added support for escape sequences to the instruments database
773 - added highly experimental support for on-the-fly instrument editing
774 within the sampler's process (by using instrument editor plugins),
775 you'll notice the new "Registered instrument editors:" message on
776 startup, added a new LSCP command:
777 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
778 to spawn a matching instrument editor for the instrument on the
779 given sampler channel, the plugin path can be overridden at compile
780 time with ./configure --enable-plugin-dir=/some/dir
781 - added experimental code for synchronizing instrument editors hosted
782 in the sampler's process to safely edit instruments while playing
783 without a crash (hopefully) by either suspending single regions
784 wherever possible or if unavoidable whole engine(s)
785 - fixed several issues in fundamental "Thread" class: set scheduling
786 policy and priority on thread level, set a minimum stack size for
787 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
788 threads simply inherited properties of starting thread instead of
789 setting their own policy and priority
790 - minor fix in our automatic stack trace mechanism on crashes, the
791 main process did not wait for the stack trace process to finish
792 its output
793 - fixed some minor memory leaks
794 - reenabled assembly features support, at the moment only for
795 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
796 - minor assembly fix in x86 features detection (don't use the PIC
797 register, to avoid relocations in the text segment at runtime)
798 - POSIX callback functions of Thread.h are hidden
799
800 * MIDI driver:
801 - dispatch bank select (MSB and LSB) messages
802
803 * audio driver:
804 - the ALSA audio output driver parameters now reflect the correct
805 parameter value ranges for the respective selected sound card
806 (patch by Till Wimmer, a bit fixed and extended)
807
808 * Gigasampler format engine:
809 - if a filter is used and EG2 finishes before EG1, let the voice
810 die when EG2 has finished (this fixes a problem with clicks and
811 voice starvation for some gigs)
812 - playback is no longer disabled during instrument loading
813 - all notes playing on a channel that changes its instrument keep
814 playing with the old instrument until they get a note off
815 command
816 - EG fix: a release value of zero could cause noises or crash
817 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
818 - EG fine tuning: when attack is zero the EG starts at a level
819 above max sustain level, which means that there is a decay phase
820 even if sustain is 100%
821 - more EG fixes: the level could sometimes go below zero and cause
822 noises or crashes
823 - minor fix of EGDecay (patch by Toshi Nagata)
824 - fixed compiler error when --enable-override-filter-type was
825 supplied to the configure script (fixes #46)
826 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
827 instead of a fix value
828 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
829 127 (solo mode) only kill voices if the respective mode really
830 changed
831
832 * LSCP server:
833 - fixed compile time error for old Bison versions
834 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
835 - parser now supports extended ASCII character set
836 (up to ASCII code 255, i.e. includes now umlauts and accents)
837 - filename arguments in LSCP commands now allow to use escape
838 sequences, that is directly literal as one of: \', \", \\, \n, \r,
839 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
840 code value like \xf2) (fixes bug #24)
841 - the following LSCP commands now also support escape sequences for at
842 least one of their text-based parameters (i.e. name, description):
843 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
844 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
845 "SET DB_INSTRUMENT_DIRECTORY NAME",
846 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
847 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
848 "FIND DB_INSTRUMENT_DIRECTORIES"
849 - returns verbose syntax errors (line and column where syntax error
850 occured, the unexpected character and the actually expected, possible
851 character(s), the latter only if less than 5 possibilities)
852 - made sure that LSCP syntax is not affected by gigedit locale
853 settings
854 - bugfix regarding strings parameter lists: all comma separated lists
855 of strings were treated as being one string containing commas
856 (fixes #57)
857
858 * Bug fixes:
859 - fixed crash occurring on certain LSCP scripts (Bug 39)
860 - another thread safety fix for lscp "load engine" and "set
861 channel audio output device"
862 - fixed a crash which occurs when reassigning the same engine
863 on a sampler channel with connected MIDI device
864 - fixed a crash which occurs when changing the number of ports of a MIDI
865 device connected to a sampler channel to number less then or equal
866 to the index of the port to which the sampler channel is connected.
867 - The previous bindings were not been disconnected when altering
868 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
869 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
870 - The active stream/voice count statistic was incorrect.
871 - notification events were not been sent for some sampler
872 channel changes
873 - added default min and max values to restrict the number of allowed
874 audio output channels and MIDI input ports
875 - the connection to the PCM interface is now closed when destroying
876 an audio output device
877 - files with slash in their path or filename could not be loaded
878
879 * test cases:
880 - updated and fixed (haven't been touched in a while)
881
882 Version 0.4.0 (24 November 2006)
883
884 * packaging changes:
885 - changed deprecated copyright attribute to license; added ldconfig
886 to post-(un)install steps; added devel package for liblinuxsampler;
887 to linuxsampler.spec (RPM)
888 - install necessary development header files for allowing 3rd party
889 applications to link against liblinuxsampler
890 - liblinuxsampler's API documentation can be generated with 'make docs'
891 (Doxygen required)
892 - added benchmark to automatically detect the best triangle LFO
893 implementation (currently either an integer math solution or a
894 di-harmonic approximation), automatic detection can be overriden
895 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
896 configure script argument though (mandatory for cross-compilation)
897 - do not automatically pick optimized gcc flags if the user already
898 provided some on his own (as CXXFLAGS)
899 - added compile time option to disable processing of All-Notes-Off MIDI
900 messages
901 - added compile time options to allow disabling the various audio and
902 MIDI drivers
903 - fixed automatic GCC CPU switch detection on PPC
904 (patch by Ebrahim Mayat)
905
906 * Gigasampler format engine:
907 - extensive synthesis optimization
908 (reimplementation of EGs and LFO(s), removed synthesis parameter
909 prerendering and the synthesis parameter matrix in general, splitting
910 each audio fragment into subfragments now where each subfragment uses
911 constant pitch and filter coefficients. The volume coefficient is
912 linearly interpolated inside a subfragment, unless
913 --disable-interpolate-volume is set.)
914 - fine tuning of the EG modulation parameters
915 - improved filter cutoff calculation by adding support for the
916 following gig parameters: Cutoff freq (used when no cutoff
917 controller is defined), Control invert, Minimum cutoff, Velocity
918 curve and Velocity range. The keyboard tracking now scales
919 cutoff frequency instead of resonance.
920 - added support for gig parameter Resonance.
921 - fixed bug in sysex handling (patch by Juan Linietsky)
922 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
923 which can be overridden with --enable-global-attenuation
924 - EG fixes: made the length of "attack hold" stage more
925 accurate. Release stage can now start before attack stage
926 ends. Cancel release didn't work when sustain was zero. Attack
927 time now has a minimal value to prevent clicks.
928 - fixed pitch changes larger than one octave
929 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
930 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
931 all modes can be altered via standard GM messages, that is CC5 for
932 altering portamento time, CC65 for enabling / disabling portamento
933 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
934 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
935 parameter) and crossfade
936 - added support for the "attenuation controller threshold" gig
937 parameter
938 - added smoothing of volume changes caused by control change
939 messages
940 - sample loop parameters are now taken from the DimensionRegion
941 instead of the wave chunk
942 - fixed keyswitching for v3 gigs with a number of keyswitch splits
943 not equal to a power of two
944 - reimplementation of the filter algorithm. The new filter is more
945 accurate and supports all gig filter types, including bandreject
946 and lowpass turbo.
947 - real support for 24 bit samples - samples are not truncated to
948 16 bits anymore
949 - support for aftertouch (channel pressure, not polyphonic
950 aftertouch)
951 - LFO1 behaviour fixed (dampening from max volume instead of
952 amplifying from 0)
953
954 * LSCP server:
955 - fixed application exit on broken pipe error (fixes bug #20)
956 - fixed the notification messages delay due to lack of
957 network activity (fixes bug #26)
958 - fixed parser bug which occured on space(s) within device parameters
959 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
960
961 * audio driver:
962 - added aRts audio output driver (by no means RT safe)
963
964 * MIDI driver:
965 - fixed legacy sysex code which caused dispatching of MIDI SysEx
966 messages several times instead of once
967 - API extension for MIDI drivers which already supply exact time stamps
968 for events (i.e. for offline rendering based MIDI drivers)
969 - added checks for bad MIDI data
970
971 * linuxsampler application:
972 - show available sampler engine types on startup
973
974 * general changes:
975 - support for muting sampler channels and solo mode of the same, two new
976 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
977 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
978 introduced for this, the behavior is the same like on a mixer console
979 (patch by Grigor Iliev, a bit adjusted). Also added configure option
980 --enable-process-muted-channels which can be used to enable the
981 processing of muted channels.
982 - support for sostenuto pedal
983 - support for monitoring the total number of active voices
984 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
985 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
986 - fixed some memory management errors
987 - fixed some concurrency problems that could lead to crashes when
988 LSCP commands were executed
989 - fixed crash when instrument loading failed previously on the same
990 sampler channel (fixes bug #36)
991
992 Version 0.3.3 (15 July 2005)
993
994 * packaging changes:
995 - fixed compilation with gcc 4.0
996
997 * Gigasampler format engine:
998 - LFO preprocessing was performed even though the respective LFO was
999 disabled by the instrument patch (minor efficiency fix)
1000 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1001 for volume ramp downs in the same fragment (needed for current voice
1002 stealing implementation) then simply inform the user with a warning
1003 about possible click sounds and reduce the volume ramp down
1004 appropriately instead of cancelling the audio device connection
1005
1006 Version 0.3.2 (24 June 2005)
1007
1008 * packaging changes:
1009 - updated autotools build files to compile on OS X
1010 (conditional compilation of CoreMIDI and MidiShare drivers)
1011 - hand-crafted assembly optimization code can be disabled with
1012 './configure --disable-asm' (definitely not recommended)
1013 - fixed 'make dist' rule to include all necessary files
1014 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1015 (due to 'dist-bzip2' automake option)
1016
1017 * Gigasampler format engine:
1018 - support for the gig parameters for "release velocity response" curves
1019 - fine tuning of the EGADSR envelope
1020 - volume of release triggered samples now depends on note-on velocity,
1021 note length and gig parameter "release trigger decay" instead of
1022 note-off velocity.
1023 - revised voice stealing
1024 (fixes crash and endless loop caused by voice stealing)
1025 - don't reset scale tuning on instrument or audio output device change
1026 - handle key group conflicts right at the beginning of each fragment
1027 instead of when the respective voice is actually launched
1028 (fixes undefined behavior if stolen voices belonged to a key group -
1029 this case was followed by a "killed voice survived" error message)
1030 - fixed minor issue with null/silence samples
1031 (those stole voices even though they don't need a voice at all which
1032 resulted in "voice stealing didn't work out" messages)
1033 - don't reset volume, pan, pitch and MIDI controller values on
1034 instrument or audio output device change
1035
1036 * LSCP server:
1037 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1038 - fixed LSCP event "CHANNEL_INFO" notification
1039 (e.g. did not notify on volume changes or MIDI program change events)
1040
1041 * linuxsampler application:
1042 - added command line parameters --lscp-addr and --lscp-port to override
1043 default IP address and port of LSCP server
1044
1045 Version 0.3.1 (24 May 2005)
1046
1047 * initial release
