* Immediately apply scale tuning changes to active voices.
* Exposed scale tuning to C++ API (along to the already existing standard
  SysEx way).
* Bumped version to 1.0.0.svn21

1 Version CVS HEAD (?)
2
3 * packaging changes:
4 - fixed building with newer MinGW-w64
5 - Mac OS X: support the new dir for Core Audio SDK
6 - Mac OS X: fixed building outside source directory
7 - made sure all source files for hostplugins are included when
8 doing "make dist"
9 - removed empty directories left from the cvs to svn migration
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

24 LDFLAGS="-Wl,--no-undefined" (#190)
25 - fixed compilation with Clang 3.2
26 - removed usage of deprecated Automake variable INCLUDES
27
28 * general changes:
29 - Refactoring: moved the independent code from
30 the Gigasampler format engine to base classes
31 - command line option '--profile' is currently disabled, since the
32 respective profiling code is currently broken
33 - Introduced support for optional environment variable
34 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
35 where the sampler shall look for instrument editor plugins
36 (patch by Luis Garrido, slightly modified).
37 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
38 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
39 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
40 note (in this implementation of the sampler its simply hard routed to
41 the 1st effect send of the sampler channel, no matter what the actual
42 effect type is)
43 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
44 note (in this implementation of the sampler its simply hard routed to
45 the 2nd effect send of the sampler channel, no matter what the actual
46 effect type is)
47 - implemented support for internal LADSPA effects
48 - raised limit of program change queue from 100 to 512
49 (as suggested by Alex Stone)
50 - implemented sine LFO, pulse LFO and saw LFO
51 - experimental support for per voice equalization
52 - added command line option --exec-after-init
53 - Introduced new C++ API method:
54 EngineChannel::InstrumentFileName(int index)
55 allowing to retrieve the whole list of files used for the loaded
56 instrument on an engine channel (a.k.a. part). Some GigaStudio
57 instruments for example are splitted over several files like
58 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
59 - Added new C++ API method Sampler::GetGlobalMaxVoices().
60 - Added new C++ API method Sampler::GetGlobalMaxStreams().
61 - Added new C++ API method Sampler::SetGlobalMaxVoices().
62 - Added new C++ API method Sampler::SetGlobalMaxStreams().
63 - Various "const" and "restrict" optimizations.
64 - all engines: add pan CC value to instrument pan parameter before
65 applying panning, instead of using two separate pan functions in
66 series (#182)
67 - added a lock guard class for exception safe mutex handling and
68 used it everywhere appropriate
69 - Immediately apply scale tuning changes to active voices.
70 - Exposed scale tuning to C++ API (along to the already existing standard
71 SysEx way).
72

76 dimension zones is not a power of two
77 - made round robin use a counter for each region instead of each
78 key
79 - bugfix: pitch LFO controller "internal+aftertouch" was broken
80 - bugfix: filter keyboard tracking was broken
81 - filter performance fix (an unnecessary copy was made of the
82 filter parameters in each sub fragment)
83 - handle special case when pan parameter in gig file has max or
84 min value
85 - Exclusive Groups: don't ever stop voices of the same note,
86 doesn't sound naturally with a drumkit
87 - fixed EG1 modulation when attack or release is zero
88

404
405 Version 1.0.0 (31 July 2009)
406
407 * packaging changes:
408 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

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