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

106 dimension zones is not a power of two
107 - made round robin use a counter for each region instead of each
108 key
109 - bugfix: pitch LFO controller "internal+aftertouch" was broken
110 - bugfix: filter keyboard tracking was broken
111 - filter performance fix (an unnecessary copy was made of the
112 filter parameters in each sub fragment)
113 - handle special case when pan parameter in gig file has max or
114 min value
115 - Exclusive Groups: don't ever stop voices of the same note,
116 doesn't sound naturally with a drumkit
117 - fixed EG1 modulation when attack or release is zero
118
119 * SFZ format engine:

409 be the case in other shells).
410 - Added support for moving cursor left/right with arrow keys.
411
412 * Bug fixes:
413 - Fixed crash which may occur when MIDI key + transpose is out of range
414 - minor valgrind fixes
415 - fixed crash which occurred when changing an already deployed sampler
416 channel to a different engine type
417 - fixed crash when deleting a sampler channel or changing engine
418 type while an instrument load was in progress
419 - bugfix: playing a note while changing the instrument could cause
420 a crash, or give "Handing back unknown region" error messages
421 - bugfix: calling SET VOICES (which Fantasia does on start and
422 refresh) could cause instruments to be unloaded
423 - Mac OS X: fixed name collision of enum in EffectControl and
424 wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
425 - Mac OS X: fixed hanging threads
426 - Windows: disabled the previous thread fix on non-Mac systems, as
427 it caused hanging threads on Windows
428 - Fixed possible crashes due to corrupted MIDI/audio device list
429 after MIDI/audio device creation failure
430 - When creating MIDI instrument map entries with "PERSISTENT" type, the
431 instruments were uselessly precached with zero samples, however it still
432 took the full preloading time and on 1st program change the respective
433 instrument was completely reloaded again.
434 - fixed handling of rapid bank select and program change messages
435 sent to the same sampler channel (patch from the Open Octave
436 project, slightly adjusted)
437 - fixed crash when trying to create an effect instance with controls
438 which min and/or max values depend on the sample rate
439 - fixed bug #162
440 - bugfix: LADSPA_PATH was not evaluated correctly when containing
441 multiple paths (#165)
442 - thread safety fixes for the instrument loading thread
443 - bugfix: instrument loading crashed for sfz and sf2 in Ardour
444 (#176)
445 - more thread safety fixes for the instrument loading thread
446 - sfz/sf2 engine: fixed crash when using small audio fragment size
447 - Mac OS X: fixed crash when unloading plugin on 10.7 and later
448 - Mac OS X: fixed process hang when unloading 32-bit plugin (bug
449 introduced in previous fix)
450 - fixed crash when a channel received a program change while
451 playing a note in a key group
452 - fixed erroneous error message piping in VoiceBase.h
453 (labelled "Disk stream not available in time")
454 - Update effects on sample rate & period size changes (to avoid
455 crashes and noise on such transitions).
456 - ignore missing LADSPA paths without ignoring valid LADSPA paths
457 (fixes #208)
458 - Fixed bug in LSCP grammar definition which caused a statement like
459 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
460 practically irrelevant, however it caused problems with the new LSCP
461 shell's auto completion feature).
462
463 Version 1.0.0 (31 July 2009)
464
465 * packaging changes:
466 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
467 causing e.g. the libgig test to fail when
468 "./configure --disable-jack-driver" was used
469 (patch by Alexis Ballier)
470 - fixed compilation with gcc 4.3
471 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
472 - fixed configure so it detects x86_64 (#107)
473 - fixes for building with newer MinGW versions
474 - fix for building with bison 2.4 (#111)
475 - fixed building with libgig installed in a non-standard directory
476 - minor fix in configure for mmsystem.h detection on MinGW
477 - Windows: look for editor plugins and Fantasia using base
478 directory of liblinuxsampler dll (look in the same directory and one
479 directory above)
480 - configure script fix: removed unconditional use of SSE
481 - fixed building with sqlite installed in a non-standard directory
482 - when cross-compiling, don't try to create instruments.db
483 - fix for new mingw-w64 version, which has usleep
484
485 * general changes:
486 - bugfix: on some POSIX systems instrument editor plugins refused to
487 load as we used a non-portable Linux specific struct field
488 (fixes bug #70, patch by Ronald Baljeu)
489 - fixed endless loop which occured when loading an instrument editor
490 plugin DLL on Windows systems failed
491 - fixed memory leaks that occurred when liblinuxsampler was unloaded
492 - optimized the SynchronizedConfig class so it doesn't wait
493 unnecessarily long after an update
494 - added support for notifying instrument editors on note-on / note-off
495 events (e.g. to highlight the pressed keys on the virtual keyboard
496 of gigedit)
497 - added support for triggering notes by instrument editors (see above)
498 - be verbose on DLL load errors (on Linux)
499 - fixed di-harmonic triangle LFO implementation (this LFO implementation
500 is only used by very few systems, most pick the int math
501 implementation, which is usually faster)
502 - fixes for audio drivers with varying buffer sizes
503 - experimental support for running LinuxSampler as a DSSI, LV2 and
504 VST plugin
505 - notification events for stream/voice count statistics are now sent
506 only when there are actual changes
507 - added memory ordering constraints to improve stability on
508 multi-core and multi-cpu systems
509 - maximum voices and disk streams can now be altered at runtime
510 - fixed CPU feature detection on x86_64 (maybe fixes #108)
511 - automatic stacktrace mechanism is now turned off by default and can
512 be switched on by command line option "--stacktrace" (the automatic
513 stacktrace mechanism seems to be broken on most systems at the moment)
514 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
515 a pointer to the launched InstrumentEditor object
516 - added optional 3rd party user data parameter for following
517 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
518 InstrumentEditor::Launch(),
519 InstrumentManager::LaunchInstrumentEditor()
520 - theoretical fix: made SynchronizedConfig follow C++0x memory
521 model more strictly
522 - fixes for using large audio device buffers
523 - Windows: add the installation directory to the DLL search path
524 when loading an editor plugin (solves problems with VST and
525 gigedit on systems with other GTK versions installed)
526 - updated linuxsampler man page
527
528 * audio driver:
529 - removed the nonsense audio channel constraint (which was hard coded to
530 max. 100 audio channels) for most audio drivers
531 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
532 opposed to the LSCP specs
533 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
534 reflected the wrong value
535 - fixed a memory management bug in ASIO driver
536 - Makefile fix: JACK_CFLAGS wasn't used
537 - JACK: use jack_client_open instead of the deprecated
538 jack_client_new
539 - added (experimental) CoreAudio driver
540 - applied old fixes to the ASIO driver that were included in the
541 previous binary release but accidentally never committed to CVS
542 (fixes #117)
543 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
544 win64)
545 - VST: added support for sample rate and buffer size changes
546 - VST: close editor (Fantasia) when the VST is removed
547 - VST: avoid opening Fantasia more than once for each VST instance
548 - VST: export main function as "main" on Linux too (fix for
549 energyXT)
550 - VST: changed number of output channels from one stereo to 16
551 stereo
552 - added channel routing, fxsends and midi maps to the settings
553 stored in the plugin state
554 - performance optimization of AudioChannel::MixTo() and
555 AudioChannel::CopyTo() methods using GCC vector exensions
556 (if available)
557 - ASIO fixes: avoid initializing the device twice, avoid throwing
558 exception when getting parameters from a disconnected device
559
560 * MIDI driver:
561 - added JACK MIDI driver
562 - dispatch bank select as ordinary CC as well, the user might seriously
563 want to (mis)use it for some purpose ("fixed" in all current MIDI
564 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
565 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
566 CoreMidi or AU
567 - fixed mingw-w64 compilation error in MME driver
568 - made program change handling in MIDI thread real-time safe by
569 moving the logic to a non-RT thread
570 - fixed minor memory leak in ALSA driver
571
572 * instruments database:
573 - avoid time consuming samples scanning when adding instruments
574 to the instruments database
575 - added support for handling lost files in the instruments database
576 - Implemented option for adding instruments in separate directories
577 in the instruments database
578 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
579 - work-around for missing fnmatch function on Windows to make
580 instrument database compilable
581 - added instrument database support on Windows
582 works with both standalone mode and VST plugin.
583 the instruments DB file is located in
584 %USERPROFILE%\.linuxsampler\instruments.db which allows different
585 databases for each windows user
586 if no DB is present it automatically creates the .linuxsampler subdir
587 and then creates an empty DB
588 - fixed recursive import, which was broken on Windows
589
590 * Gigasampler format engine:
591 - fixed a memory leak that could happen when a channel was deleted
592 while notes were playing
593 - made it possible to load an instrument even if the audio thread
594 isn't running
595 - added partial support for the "Controller Triggered" MIDI rule,
596 enough for piano gigs with pedal noise samples
597 - minor fix: only mark FX sends as being modified if really the
598 respective FX send MIDI controller was used
599 - added support for GM global device volume SysEx message
600 (can be selected at compile time to either apply globally to the
601 whole sampler [default] or only to the sampler channels that are
602 connected to the respective MIDI input port the SysEx message arrived
603 on)
604 - bugfix: notes triggered at position 0 in the audio buffer were
605 sometimes wrongly killed in the same buffer, causing no sound to
606 be played
607 - added support for chromatic / drumkit mode Roland GS Sysex message
608 which is usally used to switch a part between chromatic sounds and
609 drumkit sounds (as opposed to their common default setting of MIDI
610 part 10 being a drumkit part and all other ones chromatic parts), in
611 LS however one can switch between the first 16 MIDI instrument maps
612 defined for the sampler
613 - made it possible to create multiple sample channels even if the
614 audio thread isn't running
615 - fixed crash when removing channel with active voices (#116)
616 - bugfix: on sample reference changes (instrument editor), only
617 un-cache the respective sample if it's really not used by any
618 sampler engine anymore
619 - re-cache samples in case they were changed by an instrument editor,
620 e.g. when a sample was added while playing (#82)
621 - fixed hanging notes which occured when note-off event had the exact
622 same time stamp as the voice's note-on event and occured both in the
623 same audio fragment cycle (fixes bug #112)
624 - added support for the "fine tune" and "pitch bend range"
625 instrument-level gig parameters
626 - fixed minor artifacts in pitch bend handling
627 - added support for GS Reset SysEx message
628 - allow gig files to use unlimited downward pitch shifting
629 - added a limit check for upward pitch shifting
630 - bugfix: sometimes, when playing a note twice fast, the second
631 note was silent
632 - fixed crash happening when a pitch bend event arrived at the
633 same time a new instrument was loading
634
635 * LSCP server:
636 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
637 react on MIDI data arriving on certain sampler channels (so far only
638 Note-On and Note-Off events are sent via this LSCP event)
639 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
640 react on MIDI data arriving on certain MIDI input devices (so far only
641 Note-On and Note-Off events are sent via this LSCP event)
642 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
643 SET DB_INSTRUMENT FILE_PATH
644 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
645 frontends to send MIDI messages to specific sampler channel
646 - added two additional fields to GET FILE INSTRUMENT INFO command -
647 KEY_BINDINGS and KEYSWITCH_BINDINGS
648 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
649 was incorrect
650 - Optimized the retrieval of the MIDI instrument mappings
651 - added new LSCP command "SET VOICES" to globally alter the maximum
652 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
653 be triggered respectively
654 - added new LSCP command "SET STREAMS" to globally alter the maximum
655 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
656 which will be triggered respectively
657 - bugfix: retry if "select" returns EINTR (this fixes a crash when
658 a gigedit file dialog is opened)
659 - close all connections when LSCPServer is deleted
660 - hard close of all sockets on exit
661 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
662 driver
663
664 * Bug fixes:
665 - fixed a crash which occurs when removing a sampler channel waiting
666 to start instrument loading after another channel
667 - fixed a crash which occurs when removing a sampler channel with
668 instrument loading in progress (bug #113)
669 - fixed termination caused by uncaught exception when adding MIDI
670 instrument with PERSISTENT load mode
671 - fixed possible iterator invalidations when resetting the sampler
672 - fixed memory leaks when issuing the following LSCP commands:
673 GET AUDIO_OUTPUT_DRIVER INFO
674 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
675 GET MIDI_INPUT_DRIVER INFO
676 GET MIDI_INPUT_DRIVER_PARAMETER INFO
677 - fixed possible compilation error when sqlite is not present
678 - fixed orphaned pointers when setting maximum voices limit (bug #118)
679 - fixed crash when changing the audio output device of a sampler
680 channel with loaded instrument and start playing notes
681 - fixed endless loop in Engine::SuspendAll() (bug #120)
682 - fixed a low-level atomic load function that was broken on 64-bit
683 PowerPC, which probably could cause crashes on that platform
684 - fixed a memory management error which could cause a crash when a
685 plugin was unloaded
686 - bugfix: two private structs had the same name, which could cause
687 problems if the linker chose the wrong constructor
688 - fixed low-level ConditionServer usage bug that caused lockups on
689 Windows
690
691
692 Version 0.5.1 (6 December 2007)
693
694 * packaging changes:
695 - added autoconf checks for pthread library
696 - added autoconf check for pthread bug found on certain NPTL-enabled
697 glibc versions (see Gentoo bug report #194076)
698 - added autoconf checks for MS Windows
699
700 * general changes:
701 - bugfix: the thread used by an editor plugin didn't die when the
702 editor closed
703 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
704 out all the space. operator--() did not apply size_mask after
705 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
706 order to avoid problems with the _NonVolatileReader functions.
707 - bugfix: Stream.h: added a missing divide by BytesPerSample in
708 GetWriteSpace(). Since this function is currently only used in
709 the stream's qsort() compare function, it didn't trigger any
710 bugs.
711 - Resampler.h, Synthesizer.h: cubic interpolation now works in
712 24bit mode too. Faster method to read 24bit words on little
713 endian machines (x86): replaced 3 byte reads + shifts with a 1
714 unaligned 32bit read and shift
715 - experimental support for MS Windows (MIDI input via MME, AUDIO
716 output via ASIO)
717 - made handling of SIGINT signal (Ctrl-C) a bit more robust
718 - support for monitoring the total number of active disk streams
719 (new LSCP commands: GET TOTAL_STREAM_COUNT,
720 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
721
722 * AUDIO driver:
723 - added Windows ASIO low latency audio driver
724
725 * MIDI driver:
726 - added MME Windows MIDI driver
727
728 * LSCP server:
729 - added support for Windows style path / filenames, however with
730 forward slash path separators instead of backslash
731 (i.e. "C:/foo/bar.gig")
732 - allow naughty liblscp to send non-string device parameters within
733 apostrophes as well
734 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
735 "LIST FILE INSTRUMENTS <file>" and
736 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
737 about an arbitrary instrument file on the system where the sampler is
738 running on
739
740 Version 0.5.0 (15 October 2007)
741
742 * packaging changes:
743 - config.h is not going to be installed along with liblinuxsampler's
744 API header files anymore
745 - only the API relevant header (and source) files will be exported to
746 the Doxygen API documentation (explicitly listed in Doxyfile.in)
747 - added completely new XCode project files for Mac OSX which is now
748 capable to execute our autoconf environment, thus no need anymore
749 to maintain the compile time configuration file (osx/version.h) for
750 OSX manually (patch by Toshi Nagata)
751 - fixed buggy boolean --enable-foo / --disable-foo configure script
752 parameters
753 - global.h now only covers global definitions that are needed for the
754 C++ API header files, all implementation internal global definitions
755 are now in global_private.h
756 - atomic.h is not exposed to the C++ API anymore
757 - no need to include config.h anymore for using LS's API header files
758 - fixed warnings in API doc generation
759
760 * general changes:
761 - replaced the old, confusing MIDI program change mechanism by a
762 flexible MIDI instrument mapper which allows to map arbitrary
763 (MIDI bank, MIDI program) pairs with arbitrary
764 (engine type, instrument file, file index) triplets which will be
765 loaded on the respective channel when such MIDI program change
766 messages arrive, beside that, each entry allows to define a life-time
767 strategy for the instrument, so the user can define whether the
768 instrument should i.e. be permanently loaded (to be able to switch
769 quickly among sounds) or i.e. loaded just on demand when the
770 respective program change arrives (to safe RAM space), as well as a
771 global volume factor for each entry, so the user can adjust the volume
772 dynamic of his mapped instrument collection without having to modify
773 the instrument files, also one can manage arbitrary amount of such
774 MIDI instrument maps and assign each sampler channel individually
775 a certain map, so that i.e. separation of normal instruments and
776 drumkits is possible
777 - new notification events for tracking changes to audio/MIDI devices,
778 MIDI instrument maps, MIDI instruments, FX sends, global volume.
779 - sampler was limited to load max. 200 instruments in the background
780 due to a constant size RingBuffer FIFO which is now replaced by a
781 dynamic (unlimited) size std::list FIFO
782 - added FX sends, these allow to route audio signals to arbitrary audio
783 output channels for being processed by external effect processors
784 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
785 controllers
786 - global (sampler wide) volume can now be controlled at runtime
787 - Implemented new, improved notification system
788 - fixed compilation errors regarding OSX
789 (patch by Toshi Nagata)
790 - implemented instruments database
791 - added support for escape sequences to the instruments database
792 - added highly experimental support for on-the-fly instrument editing
793 within the sampler's process (by using instrument editor plugins),
794 you'll notice the new "Registered instrument editors:" message on
795 startup, added a new LSCP command:
796 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
797 to spawn a matching instrument editor for the instrument on the
798 given sampler channel, the plugin path can be overridden at compile
799 time with ./configure --enable-plugin-dir=/some/dir
800 - added experimental code for synchronizing instrument editors hosted
801 in the sampler's process to safely edit instruments while playing
802 without a crash (hopefully) by either suspending single regions
803 wherever possible or if unavoidable whole engine(s)
804 - fixed several issues in fundamental "Thread" class: set scheduling
805 policy and priority on thread level, set a minimum stack size for
806 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
807 threads simply inherited properties of starting thread instead of
808 setting their own policy and priority
809 - minor fix in our automatic stack trace mechanism on crashes, the
810 main process did not wait for the stack trace process to finish
811 its output
812 - fixed some minor memory leaks
813 - reenabled assembly features support, at the moment only for
814 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
815 - minor assembly fix in x86 features detection (don't use the PIC
816 register, to avoid relocations in the text segment at runtime)
817 - POSIX callback functions of Thread.h are hidden
818
819 * MIDI driver:
820 - dispatch bank select (MSB and LSB) messages
821
822 * audio driver:
823 - the ALSA audio output driver parameters now reflect the correct
824 parameter value ranges for the respective selected sound card
825 (patch by Till Wimmer, a bit fixed and extended)
826
827 * Gigasampler format engine:
828 - if a filter is used and EG2 finishes before EG1, let the voice
829 die when EG2 has finished (this fixes a problem with clicks and
830 voice starvation for some gigs)
831 - playback is no longer disabled during instrument loading
832 - all notes playing on a channel that changes its instrument keep
833 playing with the old instrument until they get a note off
834 command
835 - EG fix: a release value of zero could cause noises or crash
836 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
837 - EG fine tuning: when attack is zero the EG starts at a level
838 above max sustain level, which means that there is a decay phase
839 even if sustain is 100%
840 - more EG fixes: the level could sometimes go below zero and cause
841 noises or crashes
842 - minor fix of EGDecay (patch by Toshi Nagata)
843 - fixed compiler error when --enable-override-filter-type was
844 supplied to the configure script (fixes #46)
845 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
846 instead of a fix value
847 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
848 127 (solo mode) only kill voices if the respective mode really
849 changed
850
851 * LSCP server:
852 - fixed compile time error for old Bison versions
853 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
854 - parser now supports extended ASCII character set
855 (up to ASCII code 255, i.e. includes now umlauts and accents)
856 - filename arguments in LSCP commands now allow to use escape
857 sequences, that is directly literal as one of: \', \", \\, \n, \r,
858 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
859 code value like \xf2) (fixes bug #24)
860 - the following LSCP commands now also support escape sequences for at
861 least one of their text-based parameters (i.e. name, description):
862 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
863 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
864 "SET DB_INSTRUMENT_DIRECTORY NAME",
865 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
866 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
867 "FIND DB_INSTRUMENT_DIRECTORIES"
868 - returns verbose syntax errors (line and column where syntax error
869 occured, the unexpected character and the actually expected, possible
870 character(s), the latter only if less than 5 possibilities)
871 - made sure that LSCP syntax is not affected by gigedit locale
872 settings
873 - bugfix regarding strings parameter lists: all comma separated lists
874 of strings were treated as being one string containing commas
875 (fixes #57)
876
877 * Bug fixes:
878 - fixed crash occurring on certain LSCP scripts (Bug 39)
879 - another thread safety fix for lscp "load engine" and "set
880 channel audio output device"
881 - fixed a crash which occurs when reassigning the same engine
882 on a sampler channel with connected MIDI device
883 - fixed a crash which occurs when changing the number of ports of a MIDI
884 device connected to a sampler channel to number less then or equal
885 to the index of the port to which the sampler channel is connected.
886 - The previous bindings were not been disconnected when altering
887 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
888 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
889 - The active stream/voice count statistic was incorrect.
890 - notification events were not been sent for some sampler
891 channel changes
892 - added default min and max values to restrict the number of allowed
893 audio output channels and MIDI input ports
894 - the connection to the PCM interface is now closed when destroying
895 an audio output device
896 - files with slash in their path or filename could not be loaded
897
898 * test cases:
899 - updated and fixed (haven't been touched in a while)
900
901 Version 0.4.0 (24 November 2006)
902
903 * packaging changes:
904 - changed deprecated copyright attribute to license; added ldconfig
905 to post-(un)install steps; added devel package for liblinuxsampler;
906 to linuxsampler.spec (RPM)
907 - install necessary development header files for allowing 3rd party
908 applications to link against liblinuxsampler
909 - liblinuxsampler's API documentation can be generated with 'make docs'
910 (Doxygen required)
911 - added benchmark to automatically detect the best triangle LFO
912 implementation (currently either an integer math solution or a
913 di-harmonic approximation), automatic detection can be overriden
914 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
915 configure script argument though (mandatory for cross-compilation)
916 - do not automatically pick optimized gcc flags if the user already
917 provided some on his own (as CXXFLAGS)
918 - added compile time option to disable processing of All-Notes-Off MIDI
919 messages
920 - added compile time options to allow disabling the various audio and
921 MIDI drivers
922 - fixed automatic GCC CPU switch detection on PPC
923 (patch by Ebrahim Mayat)
924
925 * Gigasampler format engine:
926 - extensive synthesis optimization
927 (reimplementation of EGs and LFO(s), removed synthesis parameter
928 prerendering and the synthesis parameter matrix in general, splitting
929 each audio fragment into subfragments now where each subfragment uses
930 constant pitch and filter coefficients. The volume coefficient is
931 linearly interpolated inside a subfragment, unless
932 --disable-interpolate-volume is set.)
933 - fine tuning of the EG modulation parameters
934 - improved filter cutoff calculation by adding support for the
935 following gig parameters: Cutoff freq (used when no cutoff
936 controller is defined), Control invert, Minimum cutoff, Velocity
937 curve and Velocity range. The keyboard tracking now scales
938 cutoff frequency instead of resonance.
939 - added support for gig parameter Resonance.
940 - fixed bug in sysex handling (patch by Juan Linietsky)
941 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
942 which can be overridden with --enable-global-attenuation
943 - EG fixes: made the length of "attack hold" stage more
944 accurate. Release stage can now start before attack stage
945 ends. Cancel release didn't work when sustain was zero. Attack
946 time now has a minimal value to prevent clicks.
947 - fixed pitch changes larger than one octave
948 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
949 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
950 all modes can be altered via standard GM messages, that is CC5 for
951 altering portamento time, CC65 for enabling / disabling portamento
952 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
953 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
954 parameter) and crossfade
955 - added support for the "attenuation controller threshold" gig
956 parameter
957 - added smoothing of volume changes caused by control change
958 messages
959 - sample loop parameters are now taken from the DimensionRegion
960 instead of the wave chunk
961 - fixed keyswitching for v3 gigs with a number of keyswitch splits
962 not equal to a power of two
963 - reimplementation of the filter algorithm. The new filter is more
964 accurate and supports all gig filter types, including bandreject
965 and lowpass turbo.
966 - real support for 24 bit samples - samples are not truncated to
967 16 bits anymore
968 - support for aftertouch (channel pressure, not polyphonic
969 aftertouch)
970 - LFO1 behaviour fixed (dampening from max volume instead of
971 amplifying from 0)
972
973 * LSCP server:
974 - fixed application exit on broken pipe error (fixes bug #20)
975 - fixed the notification messages delay due to lack of
976 network activity (fixes bug #26)
977 - fixed parser bug which occured on space(s) within device parameters
978 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
979
980 * audio driver:
981 - added aRts audio output driver (by no means RT safe)
982
983 * MIDI driver:
984 - fixed legacy sysex code which caused dispatching of MIDI SysEx
985 messages several times instead of once
986 - API extension for MIDI drivers which already supply exact time stamps
987 for events (i.e. for offline rendering based MIDI drivers)
988 - added checks for bad MIDI data
989
990 * linuxsampler application:
991 - show available sampler engine types on startup
992
993 * general changes:
994 - support for muting sampler channels and solo mode of the same, two new
995 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
996 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
997 introduced for this, the behavior is the same like on a mixer console
998 (patch by Grigor Iliev, a bit adjusted). Also added configure option
999 --enable-process-muted-channels which can be used to enable the
1000 processing of muted channels.
1001 - support for sostenuto pedal
1002 - support for monitoring the total number of active voices
1003 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1004 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1005 - fixed some memory management errors
1006 - fixed some concurrency problems that could lead to crashes when
1007 LSCP commands were executed
1008 - fixed crash when instrument loading failed previously on the same
1009 sampler channel (fixes bug #36)
1010
1011 Version 0.3.3 (15 July 2005)
1012
1013 * packaging changes:
1014 - fixed compilation with gcc 4.0
1015
1016 * Gigasampler format engine:
1017 - LFO preprocessing was performed even though the respective LFO was
1018 disabled by the instrument patch (minor efficiency fix)
1019 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1020 for volume ramp downs in the same fragment (needed for current voice
1021 stealing implementation) then simply inform the user with a warning
1022 about possible click sounds and reduce the volume ramp down
1023 appropriately instead of cancelling the audio device connection
1024
1025 Version 0.3.2 (24 June 2005)
1026
1027 * packaging changes:
1028 - updated autotools build files to compile on OS X
1029 (conditional compilation of CoreMIDI and MidiShare drivers)
1030 - hand-crafted assembly optimization code can be disabled with
1031 './configure --disable-asm' (definitely not recommended)
1032 - fixed 'make dist' rule to include all necessary files
1033 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1034 (due to 'dist-bzip2' automake option)
1035
1036 * Gigasampler format engine:
1037 - support for the gig parameters for "release velocity response" curves
1038 - fine tuning of the EGADSR envelope
1039 - volume of release triggered samples now depends on note-on velocity,
1040 note length and gig parameter "release trigger decay" instead of
1041 note-off velocity.
1042 - revised voice stealing
1043 (fixes crash and endless loop caused by voice stealing)
1044 - don't reset scale tuning on instrument or audio output device change
1045 - handle key group conflicts right at the beginning of each fragment
1046 instead of when the respective voice is actually launched
1047 (fixes undefined behavior if stolen voices belonged to a key group -
1048 this case was followed by a "killed voice survived" error message)
1049 - fixed minor issue with null/silence samples
1050 (those stole voices even though they don't need a voice at all which
1051 resulted in "voice stealing didn't work out" messages)
1052 - don't reset volume, pan, pitch and MIDI controller values on
1053 instrument or audio output device change
1054
1055 * LSCP server:
1056 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1057 - fixed LSCP event "CHANNEL_INFO" notification
1058 (e.g. did not notify on volume changes or MIDI program change events)
1059
1060 * linuxsampler application:
1061 - added command line parameters --lscp-addr and --lscp-port to override
1062 default IP address and port of LSCP server
1063
1064 Version 0.3.1 (24 May 2005)
1065
1066 * initial release
