4 - LV2 "state" extension support (patch by David Robillard)
6 * packaging changes:
7 - fixed building with newer MinGW-w64
8 - Mac OS X: support the new dir for Core Audio SDK
9 - Mac OS X: fixed building outside source directory
10 - made sure all source files for hostplugins are included when
11 doing "make dist"
12 - removed empty directories left from the cvs to svn migration
13 - fixed compilation with gcc 4.6.1
14 - another "make dist" fix, for the LV2 plugin
15 - made --enable-pthread-testcancel default on Mac OS X
16 - minor Makefile fix for building lscpparser when build and source
17 directories are separate
18 - Mac OS X: made it possible to specify plugin installation dir to
19 configure
20 - Mac OS X: Makefile fix for the install-strip target
21 - fixed compilation with gcc 4.7
22 - fixed configure script error with old autoconf versions
23 - lsatomic.h: use gcc provided atomic functions if building with
24 gcc 4.7 and C++11
25 - modernized configure script
27 * general changes:
28 - Refactoring: moved the independent code from
29 the Gigasampler format engine to base classes
30 - command line option '--profile' is currently disabled, since the
31 respective profiling code is currently broken
32 - Introduced support for optional environment variable
33 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
34 where the sampler shall look for instrument editor plugins
35 (patch by Luis Garrido, slightly modified).
36 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
37 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
38 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
39 note (in this implementation of the sampler its simply hard routed to
40 the 1st effect send of the sampler channel, no matter what the actual
41 effect type is)
42 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
43 note (in this implementation of the sampler its simply hard routed to
44 the 2nd effect send of the sampler channel, no matter what the actual
45 effect type is)
46 - implemented support for internal LADSPA effects
47 - raised limit of program change queue from 100 to 512
48 (as suggested by Alex Stone)

53 EngineChannel::InstrumentFileName(int index)
54 allowing to retrieve the whole list of files used for the loaded
55 instrument on an engine channel (a.k.a. part). Some GigaStudio
56 instruments for example are splitted over several files like
57 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
59 * Gigasampler format engine:
60 - implemented the "round robin keyboard" dimension
61 - fixed round robin and random dimensions for cases when number of

63 - made round robin use a counter for each region instead of each
64 key
66 * SFZ format engine:

336 - When creating MIDI instrument map entries with "PERSISTENT" type, the
337 instruments were uselessly precached with zero samples, however it still
338 took the full preloading time and on 1st program change the respective
339 instrument was completely reloaded again.

357 playing a note in a key group
359 Version 1.0.0 (31 July 2009)
361 * packaging changes:
362 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
363 causing e.g. the libgig test to fail when
364 "./configure --disable-jack-driver" was used

374 directory of liblinuxsampler dll (look in the same directory and one
375 directory above)

381 * general changes:
382 - bugfix: on some POSIX systems instrument editor plugins refused to
383 load as we used a non-portable Linux specific struct field
384 (fixes bug #70, patch by Ronald Baljeu)
385 - fixed endless loop which occured when loading an instrument editor
386 plugin DLL on Windows systems failed
387 - fixed memory leaks that occurred when liblinuxsampler was unloaded
388 - optimized the SynchronizedConfig class so it doesn't wait
389 unnecessarily long after an update
390 - added support for notifying instrument editors on note-on / note-off
391 events (e.g. to highlight the pressed keys on the virtual keyboard
392 of gigedit)
393 - added support for triggering notes by instrument editors (see above)
394 - be verbose on DLL load errors (on Linux)
395 - fixed di-harmonic triangle LFO implementation (this LFO implementation
396 is only used by very few systems, most pick the int math
397 implementation, which is usually faster)
398 - fixes for audio drivers with varying buffer sizes
399 - experimental support for running LinuxSampler as a DSSI, LV2 and
400 VST plugin

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