* LSCP shell (WIP): Added initial support for built-in LSCP reference
  documentation, which will automatically show the relevant LSCP reference
  section on screen as soon as one specific LSCP command was detected while
  typing on the command line.
* Bumped version (1.0.0.svn37).

1 Version CVS HEAD (?)
2
3 * packaging changes:
4 - fixed building with newer MinGW-w64

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:

408 line while typing (no double tab required for this feature, as it would
409 be the case in other shells).
410 - Added support for moving cursor left/right with arrow keys.
411 - Added support for built-in LSCP reference documentation, which will
412 automatically show the relevant LSCP reference section on screen as soon
413 as one specific LSCP command was detected while typing on the command
414 line.
415
416 * Bug fixes:
417 - Fixed crash which may occur when MIDI key + transpose is out of range
418 - minor valgrind fixes
419 - fixed crash which occurred when changing an already deployed sampler
420 channel to a different engine type
421 - fixed crash when deleting a sampler channel or changing engine
422 type while an instrument load was in progress
423 - bugfix: playing a note while changing the instrument could cause
424 a crash, or give "Handing back unknown region" error messages
425 - bugfix: calling SET VOICES (which Fantasia does on start and
426 refresh) could cause instruments to be unloaded
427 - Mac OS X: fixed name collision of enum in EffectControl and
428 wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
429 - Mac OS X: fixed hanging threads
430 - Windows: disabled the previous thread fix on non-Mac systems, as
431 it caused hanging threads on Windows
432 - Fixed possible crashes due to corrupted MIDI/audio device list
433 after MIDI/audio device creation failure
434 - When creating MIDI instrument map entries with "PERSISTENT" type, the
435 instruments were uselessly precached with zero samples, however it still
436 took the full preloading time and on 1st program change the respective
437 instrument was completely reloaded again.
438 - fixed handling of rapid bank select and program change messages
439 sent to the same sampler channel (patch from the Open Octave
440 project, slightly adjusted)
441 - fixed crash when trying to create an effect instance with controls
442 which min and/or max values depend on the sample rate
443 - fixed bug #162
444 - bugfix: LADSPA_PATH was not evaluated correctly when containing
445 multiple paths (#165)
446 - thread safety fixes for the instrument loading thread
447 - bugfix: instrument loading crashed for sfz and sf2 in Ardour
448 (#176)
449 - more thread safety fixes for the instrument loading thread
450 - sfz/sf2 engine: fixed crash when using small audio fragment size
451 - Mac OS X: fixed crash when unloading plugin on 10.7 and later
452 - Mac OS X: fixed process hang when unloading 32-bit plugin (bug
453 introduced in previous fix)
454 - fixed crash when a channel received a program change while
455 playing a note in a key group
456 - fixed erroneous error message piping in VoiceBase.h
457 (labelled "Disk stream not available in time")
458 - Update effects on sample rate & period size changes (to avoid
459 crashes and noise on such transitions).
460 - ignore missing LADSPA paths without ignoring valid LADSPA paths
461 (fixes #208)
462 - Fixed bug in LSCP grammar definition which caused a statement like
463 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
464 practically irrelevant, however it caused problems with the new LSCP
465 shell's auto completion feature).
466
467 Version 1.0.0 (31 July 2009)
468
469 * packaging changes:
470 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
471 causing e.g. the libgig test to fail when
472 "./configure --disable-jack-driver" was used
473 (patch by Alexis Ballier)
474 - fixed compilation with gcc 4.3
475 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
476 - fixed configure so it detects x86_64 (#107)
477 - fixes for building with newer MinGW versions
478 - fix for building with bison 2.4 (#111)
479 - fixed building with libgig installed in a non-standard directory
480 - minor fix in configure for mmsystem.h detection on MinGW
481 - Windows: look for editor plugins and Fantasia using base
482 directory of liblinuxsampler dll (look in the same directory and one
483 directory above)
484 - configure script fix: removed unconditional use of SSE
485 - fixed building with sqlite installed in a non-standard directory
486 - when cross-compiling, don't try to create instruments.db
487 - fix for new mingw-w64 version, which has usleep
488
489 * general changes:
490 - bugfix: on some POSIX systems instrument editor plugins refused to
491 load as we used a non-portable Linux specific struct field
492 (fixes bug #70, patch by Ronald Baljeu)
493 - fixed endless loop which occured when loading an instrument editor
494 plugin DLL on Windows systems failed
495 - fixed memory leaks that occurred when liblinuxsampler was unloaded
496 - optimized the SynchronizedConfig class so it doesn't wait
497 unnecessarily long after an update
498 - added support for notifying instrument editors on note-on / note-off
499 events (e.g. to highlight the pressed keys on the virtual keyboard
500 of gigedit)
501 - added support for triggering notes by instrument editors (see above)
502 - be verbose on DLL load errors (on Linux)
503 - fixed di-harmonic triangle LFO implementation (this LFO implementation
504 is only used by very few systems, most pick the int math
505 implementation, which is usually faster)
506 - fixes for audio drivers with varying buffer sizes
507 - experimental support for running LinuxSampler as a DSSI, LV2 and
508 VST plugin
509 - notification events for stream/voice count statistics are now sent
510 only when there are actual changes
511 - added memory ordering constraints to improve stability on
512 multi-core and multi-cpu systems
513 - maximum voices and disk streams can now be altered at runtime
514 - fixed CPU feature detection on x86_64 (maybe fixes #108)
515 - automatic stacktrace mechanism is now turned off by default and can
516 be switched on by command line option "--stacktrace" (the automatic
517 stacktrace mechanism seems to be broken on most systems at the moment)
518 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
519 a pointer to the launched InstrumentEditor object
520 - added optional 3rd party user data parameter for following
521 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
522 InstrumentEditor::Launch(),
523 InstrumentManager::LaunchInstrumentEditor()
524 - theoretical fix: made SynchronizedConfig follow C++0x memory
525 model more strictly
526 - fixes for using large audio device buffers
527 - Windows: add the installation directory to the DLL search path
528 when loading an editor plugin (solves problems with VST and
529 gigedit on systems with other GTK versions installed)
530 - updated linuxsampler man page
531
532 * audio driver:
533 - removed the nonsense audio channel constraint (which was hard coded to
534 max. 100 audio channels) for most audio drivers
535 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
536 opposed to the LSCP specs
537 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
538 reflected the wrong value
539 - fixed a memory management bug in ASIO driver
540 - Makefile fix: JACK_CFLAGS wasn't used
541 - JACK: use jack_client_open instead of the deprecated
542 jack_client_new
543 - added (experimental) CoreAudio driver
544 - applied old fixes to the ASIO driver that were included in the
545 previous binary release but accidentally never committed to CVS
546 (fixes #117)
547 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
548 win64)
549 - VST: added support for sample rate and buffer size changes
550 - VST: close editor (Fantasia) when the VST is removed
551 - VST: avoid opening Fantasia more than once for each VST instance
552 - VST: export main function as "main" on Linux too (fix for
553 energyXT)
554 - VST: changed number of output channels from one stereo to 16
555 stereo
556 - added channel routing, fxsends and midi maps to the settings
557 stored in the plugin state
558 - performance optimization of AudioChannel::MixTo() and
559 AudioChannel::CopyTo() methods using GCC vector exensions
560 (if available)
561 - ASIO fixes: avoid initializing the device twice, avoid throwing
562 exception when getting parameters from a disconnected device
563
564 * MIDI driver:
565 - added JACK MIDI driver
566 - dispatch bank select as ordinary CC as well, the user might seriously
567 want to (mis)use it for some purpose ("fixed" in all current MIDI
568 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
569 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
570 CoreMidi or AU
571 - fixed mingw-w64 compilation error in MME driver
572 - made program change handling in MIDI thread real-time safe by
573 moving the logic to a non-RT thread
574 - fixed minor memory leak in ALSA driver
575
576 * instruments database:
577 - avoid time consuming samples scanning when adding instruments
578 to the instruments database
579 - added support for handling lost files in the instruments database
580 - Implemented option for adding instruments in separate directories
581 in the instruments database
582 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
583 - work-around for missing fnmatch function on Windows to make
584 instrument database compilable
585 - added instrument database support on Windows
586 works with both standalone mode and VST plugin.
587 the instruments DB file is located in
588 %USERPROFILE%\.linuxsampler\instruments.db which allows different
589 databases for each windows user
590 if no DB is present it automatically creates the .linuxsampler subdir
591 and then creates an empty DB
592 - fixed recursive import, which was broken on Windows
593
594 * Gigasampler format engine:
595 - fixed a memory leak that could happen when a channel was deleted
596 while notes were playing
597 - made it possible to load an instrument even if the audio thread
598 isn't running
599 - added partial support for the "Controller Triggered" MIDI rule,
600 enough for piano gigs with pedal noise samples
601 - minor fix: only mark FX sends as being modified if really the
602 respective FX send MIDI controller was used
603 - added support for GM global device volume SysEx message
604 (can be selected at compile time to either apply globally to the
605 whole sampler [default] or only to the sampler channels that are
606 connected to the respective MIDI input port the SysEx message arrived
607 on)
608 - bugfix: notes triggered at position 0 in the audio buffer were
609 sometimes wrongly killed in the same buffer, causing no sound to
610 be played
611 - added support for chromatic / drumkit mode Roland GS Sysex message
612 which is usally used to switch a part between chromatic sounds and
613 drumkit sounds (as opposed to their common default setting of MIDI
614 part 10 being a drumkit part and all other ones chromatic parts), in
615 LS however one can switch between the first 16 MIDI instrument maps
616 defined for the sampler
617 - made it possible to create multiple sample channels even if the
618 audio thread isn't running
619 - fixed crash when removing channel with active voices (#116)
620 - bugfix: on sample reference changes (instrument editor), only
621 un-cache the respective sample if it's really not used by any
622 sampler engine anymore
623 - re-cache samples in case they were changed by an instrument editor,
624 e.g. when a sample was added while playing (#82)
625 - fixed hanging notes which occured when note-off event had the exact
626 same time stamp as the voice's note-on event and occured both in the
627 same audio fragment cycle (fixes bug #112)
628 - added support for the "fine tune" and "pitch bend range"
629 instrument-level gig parameters
630 - fixed minor artifacts in pitch bend handling
631 - added support for GS Reset SysEx message
632 - allow gig files to use unlimited downward pitch shifting
633 - added a limit check for upward pitch shifting
634 - bugfix: sometimes, when playing a note twice fast, the second
635 note was silent
636 - fixed crash happening when a pitch bend event arrived at the
637 same time a new instrument was loading
638
639 * LSCP server:
640 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
641 react on MIDI data arriving on certain sampler channels (so far only
642 Note-On and Note-Off events are sent via this LSCP event)
643 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
644 react on MIDI data arriving on certain MIDI input devices (so far only
645 Note-On and Note-Off events are sent via this LSCP event)
646 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
647 SET DB_INSTRUMENT FILE_PATH
648 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
649 frontends to send MIDI messages to specific sampler channel
650 - added two additional fields to GET FILE INSTRUMENT INFO command -
651 KEY_BINDINGS and KEYSWITCH_BINDINGS
652 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
653 was incorrect
654 - Optimized the retrieval of the MIDI instrument mappings
655 - added new LSCP command "SET VOICES" to globally alter the maximum
656 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
657 be triggered respectively
658 - added new LSCP command "SET STREAMS" to globally alter the maximum
659 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
660 which will be triggered respectively
661 - bugfix: retry if "select" returns EINTR (this fixes a crash when
662 a gigedit file dialog is opened)
663 - close all connections when LSCPServer is deleted
664 - hard close of all sockets on exit
665 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
666 driver
667
668 * Bug fixes:
669 - fixed a crash which occurs when removing a sampler channel waiting
670 to start instrument loading after another channel
671 - fixed a crash which occurs when removing a sampler channel with
672 instrument loading in progress (bug #113)
673 - fixed termination caused by uncaught exception when adding MIDI
674 instrument with PERSISTENT load mode
675 - fixed possible iterator invalidations when resetting the sampler
676 - fixed memory leaks when issuing the following LSCP commands:
677 GET AUDIO_OUTPUT_DRIVER INFO
678 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
679 GET MIDI_INPUT_DRIVER INFO
680 GET MIDI_INPUT_DRIVER_PARAMETER INFO
681 - fixed possible compilation error when sqlite is not present
682 - fixed orphaned pointers when setting maximum voices limit (bug #118)
683 - fixed crash when changing the audio output device of a sampler
684 channel with loaded instrument and start playing notes
685 - fixed endless loop in Engine::SuspendAll() (bug #120)
686 - fixed a low-level atomic load function that was broken on 64-bit
687 PowerPC, which probably could cause crashes on that platform
688 - fixed a memory management error which could cause a crash when a
689 plugin was unloaded
690 - bugfix: two private structs had the same name, which could cause
691 problems if the linker chose the wrong constructor
692 - fixed low-level ConditionServer usage bug that caused lockups on
693 Windows
694
695
696 Version 0.5.1 (6 December 2007)
697
698 * packaging changes:
699 - added autoconf checks for pthread library
700 - added autoconf check for pthread bug found on certain NPTL-enabled
701 glibc versions (see Gentoo bug report #194076)
702 - added autoconf checks for MS Windows
703
704 * general changes:
705 - bugfix: the thread used by an editor plugin didn't die when the
706 editor closed
707 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
708 out all the space. operator--() did not apply size_mask after
709 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
710 order to avoid problems with the _NonVolatileReader functions.
711 - bugfix: Stream.h: added a missing divide by BytesPerSample in
712 GetWriteSpace(). Since this function is currently only used in
713 the stream's qsort() compare function, it didn't trigger any
714 bugs.
715 - Resampler.h, Synthesizer.h: cubic interpolation now works in
716 24bit mode too. Faster method to read 24bit words on little
717 endian machines (x86): replaced 3 byte reads + shifts with a 1
718 unaligned 32bit read and shift
719 - experimental support for MS Windows (MIDI input via MME, AUDIO
720 output via ASIO)
721 - made handling of SIGINT signal (Ctrl-C) a bit more robust
722 - support for monitoring the total number of active disk streams
723 (new LSCP commands: GET TOTAL_STREAM_COUNT,
724 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
725
726 * AUDIO driver:
727 - added Windows ASIO low latency audio driver
728
729 * MIDI driver:
730 - added MME Windows MIDI driver
731
732 * LSCP server:
733 - added support for Windows style path / filenames, however with
734 forward slash path separators instead of backslash
735 (i.e. "C:/foo/bar.gig")
736 - allow naughty liblscp to send non-string device parameters within
737 apostrophes as well
738 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
739 "LIST FILE INSTRUMENTS <file>" and
740 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
741 about an arbitrary instrument file on the system where the sampler is
742 running on
743
744 Version 0.5.0 (15 October 2007)
745
746 * packaging changes:
747 - config.h is not going to be installed along with liblinuxsampler's
748 API header files anymore
749 - only the API relevant header (and source) files will be exported to
750 the Doxygen API documentation (explicitly listed in Doxyfile.in)
751 - added completely new XCode project files for Mac OSX which is now
752 capable to execute our autoconf environment, thus no need anymore
753 to maintain the compile time configuration file (osx/version.h) for
754 OSX manually (patch by Toshi Nagata)
755 - fixed buggy boolean --enable-foo / --disable-foo configure script
756 parameters
757 - global.h now only covers global definitions that are needed for the
758 C++ API header files, all implementation internal global definitions
759 are now in global_private.h
760 - atomic.h is not exposed to the C++ API anymore
761 - no need to include config.h anymore for using LS's API header files
762 - fixed warnings in API doc generation
763
764 * general changes:
765 - replaced the old, confusing MIDI program change mechanism by a
766 flexible MIDI instrument mapper which allows to map arbitrary
767 (MIDI bank, MIDI program) pairs with arbitrary
768 (engine type, instrument file, file index) triplets which will be
769 loaded on the respective channel when such MIDI program change
770 messages arrive, beside that, each entry allows to define a life-time
771 strategy for the instrument, so the user can define whether the
772 instrument should i.e. be permanently loaded (to be able to switch
773 quickly among sounds) or i.e. loaded just on demand when the
774 respective program change arrives (to safe RAM space), as well as a
775 global volume factor for each entry, so the user can adjust the volume
776 dynamic of his mapped instrument collection without having to modify
777 the instrument files, also one can manage arbitrary amount of such
778 MIDI instrument maps and assign each sampler channel individually
779 a certain map, so that i.e. separation of normal instruments and
780 drumkits is possible
781 - new notification events for tracking changes to audio/MIDI devices,
782 MIDI instrument maps, MIDI instruments, FX sends, global volume.
783 - sampler was limited to load max. 200 instruments in the background
784 due to a constant size RingBuffer FIFO which is now replaced by a
785 dynamic (unlimited) size std::list FIFO
786 - added FX sends, these allow to route audio signals to arbitrary audio
787 output channels for being processed by external effect processors
788 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
789 controllers
790 - global (sampler wide) volume can now be controlled at runtime
791 - Implemented new, improved notification system
792 - fixed compilation errors regarding OSX
793 (patch by Toshi Nagata)
794 - implemented instruments database
795 - added support for escape sequences to the instruments database
796 - added highly experimental support for on-the-fly instrument editing
797 within the sampler's process (by using instrument editor plugins),
798 you'll notice the new "Registered instrument editors:" message on
799 startup, added a new LSCP command:
800 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
801 to spawn a matching instrument editor for the instrument on the
802 given sampler channel, the plugin path can be overridden at compile
803 time with ./configure --enable-plugin-dir=/some/dir
804 - added experimental code for synchronizing instrument editors hosted
805 in the sampler's process to safely edit instruments while playing
806 without a crash (hopefully) by either suspending single regions
807 wherever possible or if unavoidable whole engine(s)
808 - fixed several issues in fundamental "Thread" class: set scheduling
809 policy and priority on thread level, set a minimum stack size for
810 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
811 threads simply inherited properties of starting thread instead of
812 setting their own policy and priority
813 - minor fix in our automatic stack trace mechanism on crashes, the
814 main process did not wait for the stack trace process to finish
815 its output
816 - fixed some minor memory leaks
817 - reenabled assembly features support, at the moment only for
818 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
819 - minor assembly fix in x86 features detection (don't use the PIC
820 register, to avoid relocations in the text segment at runtime)
821 - POSIX callback functions of Thread.h are hidden
822
823 * MIDI driver:
824 - dispatch bank select (MSB and LSB) messages
825
826 * audio driver:
827 - the ALSA audio output driver parameters now reflect the correct
828 parameter value ranges for the respective selected sound card
829 (patch by Till Wimmer, a bit fixed and extended)
830
831 * Gigasampler format engine:
832 - if a filter is used and EG2 finishes before EG1, let the voice
833 die when EG2 has finished (this fixes a problem with clicks and
834 voice starvation for some gigs)
835 - playback is no longer disabled during instrument loading
836 - all notes playing on a channel that changes its instrument keep
837 playing with the old instrument until they get a note off
838 command
839 - EG fix: a release value of zero could cause noises or crash
840 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
841 - EG fine tuning: when attack is zero the EG starts at a level
842 above max sustain level, which means that there is a decay phase
843 even if sustain is 100%
844 - more EG fixes: the level could sometimes go below zero and cause
845 noises or crashes
846 - minor fix of EGDecay (patch by Toshi Nagata)
847 - fixed compiler error when --enable-override-filter-type was
848 supplied to the configure script (fixes #46)
849 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
850 instead of a fix value
851 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
852 127 (solo mode) only kill voices if the respective mode really
853 changed
854
855 * LSCP server:
856 - fixed compile time error for old Bison versions
857 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
858 - parser now supports extended ASCII character set
859 (up to ASCII code 255, i.e. includes now umlauts and accents)
860 - filename arguments in LSCP commands now allow to use escape
861 sequences, that is directly literal as one of: \', \", \\, \n, \r,
862 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
863 code value like \xf2) (fixes bug #24)
864 - the following LSCP commands now also support escape sequences for at
865 least one of their text-based parameters (i.e. name, description):
866 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
867 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
868 "SET DB_INSTRUMENT_DIRECTORY NAME",
869 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
870 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
871 "FIND DB_INSTRUMENT_DIRECTORIES"
872 - returns verbose syntax errors (line and column where syntax error
873 occured, the unexpected character and the actually expected, possible
874 character(s), the latter only if less than 5 possibilities)
875 - made sure that LSCP syntax is not affected by gigedit locale
876 settings
877 - bugfix regarding strings parameter lists: all comma separated lists
878 of strings were treated as being one string containing commas
879 (fixes #57)
880
881 * Bug fixes:
882 - fixed crash occurring on certain LSCP scripts (Bug 39)
883 - another thread safety fix for lscp "load engine" and "set
884 channel audio output device"
885 - fixed a crash which occurs when reassigning the same engine
886 on a sampler channel with connected MIDI device
887 - fixed a crash which occurs when changing the number of ports of a MIDI
888 device connected to a sampler channel to number less then or equal
889 to the index of the port to which the sampler channel is connected.
890 - The previous bindings were not been disconnected when altering
891 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
892 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
893 - The active stream/voice count statistic was incorrect.
894 - notification events were not been sent for some sampler
895 channel changes
896 - added default min and max values to restrict the number of allowed
897 audio output channels and MIDI input ports
898 - the connection to the PCM interface is now closed when destroying
899 an audio output device
900 - files with slash in their path or filename could not be loaded
901
902 * test cases:
903 - updated and fixed (haven't been touched in a while)
904
905 Version 0.4.0 (24 November 2006)
906
907 * packaging changes:
908 - changed deprecated copyright attribute to license; added ldconfig
909 to post-(un)install steps; added devel package for liblinuxsampler;
910 to linuxsampler.spec (RPM)
911 - install necessary development header files for allowing 3rd party
912 applications to link against liblinuxsampler
913 - liblinuxsampler's API documentation can be generated with 'make docs'
914 (Doxygen required)
915 - added benchmark to automatically detect the best triangle LFO
916 implementation (currently either an integer math solution or a
917 di-harmonic approximation), automatic detection can be overriden
918 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
919 configure script argument though (mandatory for cross-compilation)
920 - do not automatically pick optimized gcc flags if the user already
921 provided some on his own (as CXXFLAGS)
922 - added compile time option to disable processing of All-Notes-Off MIDI
923 messages
924 - added compile time options to allow disabling the various audio and
925 MIDI drivers
926 - fixed automatic GCC CPU switch detection on PPC
927 (patch by Ebrahim Mayat)
928
929 * Gigasampler format engine:
930 - extensive synthesis optimization
931 (reimplementation of EGs and LFO(s), removed synthesis parameter
932 prerendering and the synthesis parameter matrix in general, splitting
933 each audio fragment into subfragments now where each subfragment uses
934 constant pitch and filter coefficients. The volume coefficient is
935 linearly interpolated inside a subfragment, unless
936 --disable-interpolate-volume is set.)
937 - fine tuning of the EG modulation parameters
938 - improved filter cutoff calculation by adding support for the
939 following gig parameters: Cutoff freq (used when no cutoff
940 controller is defined), Control invert, Minimum cutoff, Velocity
941 curve and Velocity range. The keyboard tracking now scales
942 cutoff frequency instead of resonance.
943 - added support for gig parameter Resonance.
944 - fixed bug in sysex handling (patch by Juan Linietsky)
945 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
946 which can be overridden with --enable-global-attenuation
947 - EG fixes: made the length of "attack hold" stage more
948 accurate. Release stage can now start before attack stage
949 ends. Cancel release didn't work when sustain was zero. Attack
950 time now has a minimal value to prevent clicks.
951 - fixed pitch changes larger than one octave
952 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
953 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
954 all modes can be altered via standard GM messages, that is CC5 for
955 altering portamento time, CC65 for enabling / disabling portamento
956 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
957 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
958 parameter) and crossfade
959 - added support for the "attenuation controller threshold" gig
960 parameter
961 - added smoothing of volume changes caused by control change
962 messages
963 - sample loop parameters are now taken from the DimensionRegion
964 instead of the wave chunk
965 - fixed keyswitching for v3 gigs with a number of keyswitch splits
966 not equal to a power of two
967 - reimplementation of the filter algorithm. The new filter is more
968 accurate and supports all gig filter types, including bandreject
969 and lowpass turbo.
970 - real support for 24 bit samples - samples are not truncated to
971 16 bits anymore
972 - support for aftertouch (channel pressure, not polyphonic
973 aftertouch)
974 - LFO1 behaviour fixed (dampening from max volume instead of
975 amplifying from 0)
976
977 * LSCP server:
978 - fixed application exit on broken pipe error (fixes bug #20)
979 - fixed the notification messages delay due to lack of
980 network activity (fixes bug #26)
981 - fixed parser bug which occured on space(s) within device parameters
982 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
983
984 * audio driver:
985 - added aRts audio output driver (by no means RT safe)
986
987 * MIDI driver:
988 - fixed legacy sysex code which caused dispatching of MIDI SysEx
989 messages several times instead of once
990 - API extension for MIDI drivers which already supply exact time stamps
991 for events (i.e. for offline rendering based MIDI drivers)
992 - added checks for bad MIDI data
993
994 * linuxsampler application:
995 - show available sampler engine types on startup
996
997 * general changes:
998 - support for muting sampler channels and solo mode of the same, two new
999 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1000 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1001 introduced for this, the behavior is the same like on a mixer console
1002 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1003 --enable-process-muted-channels which can be used to enable the
1004 processing of muted channels.
1005 - support for sostenuto pedal
1006 - support for monitoring the total number of active voices
1007 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1008 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1009 - fixed some memory management errors
1010 - fixed some concurrency problems that could lead to crashes when
1011 LSCP commands were executed
1012 - fixed crash when instrument loading failed previously on the same
1013 sampler channel (fixes bug #36)
1014
1015 Version 0.3.3 (15 July 2005)
1016
1017 * packaging changes:
1018 - fixed compilation with gcc 4.0
1019
1020 * Gigasampler format engine:
1021 - LFO preprocessing was performed even though the respective LFO was
1022 disabled by the instrument patch (minor efficiency fix)
1023 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1024 for volume ramp downs in the same fragment (needed for current voice
1025 stealing implementation) then simply inform the user with a warning
1026 about possible click sounds and reduce the volume ramp down
1027 appropriately instead of cancelling the audio device connection
1028
1029 Version 0.3.2 (24 June 2005)
1030
1031 * packaging changes:
1032 - updated autotools build files to compile on OS X
1033 (conditional compilation of CoreMIDI and MidiShare drivers)
1034 - hand-crafted assembly optimization code can be disabled with
1035 './configure --disable-asm' (definitely not recommended)
1036 - fixed 'make dist' rule to include all necessary files
1037 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1038 (due to 'dist-bzip2' automake option)
1039
1040 * Gigasampler format engine:
1041 - support for the gig parameters for "release velocity response" curves
1042 - fine tuning of the EGADSR envelope
1043 - volume of release triggered samples now depends on note-on velocity,
1044 note length and gig parameter "release trigger decay" instead of
1045 note-off velocity.
1046 - revised voice stealing
1047 (fixes crash and endless loop caused by voice stealing)
1048 - don't reset scale tuning on instrument or audio output device change
1049 - handle key group conflicts right at the beginning of each fragment
1050 instead of when the respective voice is actually launched
1051 (fixes undefined behavior if stolen voices belonged to a key group -
1052 this case was followed by a "killed voice survived" error message)
1053 - fixed minor issue with null/silence samples
1054 (those stole voices even though they don't need a voice at all which
1055 resulted in "voice stealing didn't work out" messages)
1056 - don't reset volume, pan, pitch and MIDI controller values on
1057 instrument or audio output device change
1058
1059 * LSCP server:
1060 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1061 - fixed LSCP event "CHANNEL_INFO" notification
1062 (e.g. did not notify on volume changes or MIDI program change events)
1063
1064 * linuxsampler application:
1065 - added command line parameters --lscp-addr and --lscp-port to override
1066 default IP address and port of LSCP server
1067
1068 Version 0.3.1 (24 May 2005)
1069
1070 * initial release
