File size: 52461 byte(s)
* MIDI drivers: Implemented missing handling of MIDI "running status".
* MME driver: pass time stamps to the sampler.

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

254 - Listen to all interfaces on Mac OS X (INADDR_ANY)
255 - VST bugfix: If the host called resume() before and after
256 changing sample rate or block size, the number of channels was
257 incorrectly set to two. This caused silence in Cubase 5.

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

399
400 Version 1.0.0 (31 July 2009)
401
402 * packaging changes:

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