File size: 52523 byte(s)
* Reverted yesterday's MME driver change for now (requires some
  additional code in RTMath for being able to work correctly).

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

90 one from the gig engine
91 - fixed memory leak and memory handling errors
92 - added support for trigger=first, trigger=legato and sw_previous
93 - allow non-numerical key values ("C#4" for example)

256 - Listen to all interfaces on Mac OS X (INADDR_ANY)
257 - VST bugfix: If the host called resume() before and after
258 changing sample rate or block size, the number of channels was

400
401 Version 1.0.0 (31 July 2009)
402
403 * packaging changes:
404 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

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