  while typing.
* Bumped version (1.0.0.svn29).

1 Version CVS HEAD (?)
2

16 configure
17 - Mac OS X: Makefile fix for the install-strip target
18 - fixed compilation with gcc 4.7
19 - fixed configure script error with old autoconf versions
20 - lsatomic.h: use gcc provided atomic functions if building with

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

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

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