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

115 more compatible
116 - added support for trigger=release and rt_decay
117 - added support for off_mode=normal
118 - added support for random, seq_position, seq_length and volume

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