37
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
95 * Gigasampler format engine:
96 - implemented the "round robin keyboard" dimension
97 - fixed round robin and random dimensions for cases when number of
98 dimension zones is not a power of two
99 - made round robin use a counter for each region instead of each
100 key
101 - bugfix: pitch LFO controller "internal+aftertouch" was broken
102 - bugfix: filter keyboard tracking was broken
103 - filter performance fix (an unnecessary copy was made of the
104 filter parameters in each sub fragment)
105 - handle special case when pan parameter in gig file has max or
106 min value
107 - Exclusive Groups: don't ever stop voices of the same note,
108 doesn't sound naturally with a drumkit
109 - fixed EG1 modulation when attack or release is zero
110
111 * SFZ format engine:
112 - Initial implementation (not usable yet)

123 more compatible
124 - added support for trigger=release and rt_decay
125 - added support for off_mode=normal
126 - added support for random, seq_position, seq_length and volume

327 the driver will automatically connect to other CoreMIDI clients' ports
328 (e.g. external MIDI devices being attached to the Mac)
329 - added support for MIDI note on velocity filter
330 - CoreMIDI: fixed memory deallocation error
331 - Fixed variable underflow in VirtualMidiDevice, which caused graphical

410 sent to the same sampler channel (patch from the Open Octave
411 project, slightly adjusted)
412 - fixed crash when trying to create an effect instance with controls
413 which min and/or max values depend on the sample rate
414 - fixed bug #162
415 - bugfix: LADSPA_PATH was not evaluated correctly when containing
416 multiple paths (#165)
417 - thread safety fixes for the instrument loading thread
418 - bugfix: instrument loading crashed for sfz and sf2 in Ardour
419 (#176)
420 - more thread safety fixes for the instrument loading thread
421 - sfz/sf2 engine: fixed crash when using small audio fragment size
422 - Mac OS X: fixed crash when unloading plugin on 10.7 and later
423 - Mac OS X: fixed process hang when unloading 32-bit plugin (bug
424 introduced in previous fix)

426 playing a note in a key group
427 - fixed erroneous error message piping in VoiceBase.h
428 (labelled "Disk stream not available in time")

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