* Added support for multiple MIDI input ports per sampler channel (added
  various new C++ API methods for this new feature/design, old C++ API
  methods are now marked as deprecated but should still provide full
  behavior backward compatibility).
* LSCP Network interface: Added the following new LSCP commands for the new
  feature mentioned above: "ADD CHANNEL MIDI_INPUT",
  C++ API changes, the old LSCP commands for MIDI input management are now
  marked as deprecated, but are still there and should provide full behavior
  backward compatibility.
* New LSCP specification document (LSCP v1.6).
* AbstractEngine::GSCheckSum(): don't allocate memory on the stack (was
  unsafe and caused compilation error with old clang 2.x).
* Bumped version (1.0.0.svn25).

1 Version CVS HEAD (?)
3 * packaging changes:
4 - fixed building with newer MinGW-w64
5 - Mac OS X: support the new dir for Core Audio SDK

10 - fixed compilation with gcc 4.6.1
11 - another "make dist" fix, for the LV2 plugin
12 - made --enable-pthread-testcancel default on Mac OS X
13 - minor Makefile fix for building lscpparser when build and source
14 directories are separate
15 - Mac OS X: made it possible to specify plugin installation dir to
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
21 gcc 4.7 and C++11
22 - modernized configure script
23 - fixed linkage error when building with
24 LDFLAGS="-Wl,--no-undefined" (#190)
25 - fixed compilation with Clang 3.2
26 - removed usage of deprecated Automake variable INCLUDES
27 - fixed building with C++11
28 - build fix: ChangeFlagRelaxed.h was missing in makefile

33 on the process's main thread
34 - fixed build error on newer MinGW
35 - support building with older jack versions
36 - support building with spaces in vst sdk path
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).

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

400 after MIDI/audio device creation failure
401 - When creating MIDI instrument map entries with "PERSISTENT" type, the
402 instruments were uselessly precached with zero samples, however it still
403 took the full preloading time and on 1st program change the respective

413 - thread safety fixes for the instrument loading thread
414 - bugfix: instrument loading crashed for sfz and sf2 in Ardour
415 (#176)
416 - more thread safety fixes for the instrument loading thread
417 - sfz/sf2 engine: fixed crash when using small audio fragment size
418 - Mac OS X: fixed crash when unloading plugin on 10.7 and later

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