* bugfix: LADSPA_PATH was not evaluated correctly when containing
  multiple paths (#165)

1 Version CVS HEAD (?)
3 * plugin changes:
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
22 * general changes:
23 - Refactoring: moved the independent code from
24 the Gigasampler format engine to base classes
25 - command line option '--profile' is currently disabled, since the
26 respective profiling code is currently broken
27 - Introduced support for optional environment variable

35 the 1st effect send of the sampler channel, no matter what the actual
36 effect type is)
37 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
38 note (in this implementation of the sampler its simply hard routed to
39 the 2nd effect send of the sampler channel, no matter what the actual

288 - bugfix: calling SET VOICES (which Fantasia does on start and
289 refresh) could cause instruments to be unloaded
290 - Mac OS X: fixed name collision of enum in EffectControl and
291 wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
292 - Mac OS X: fixed hanging threads
293 - Windows: disabled the previous thread fix on non-Mac systems, as
294 it caused hanging threads on Windows

296 after MIDI/audio device creation failure
297 - When creating MIDI instrument map entries with "PERSISTENT" type, the
298 instruments were uselessly precached with zero samples, however it still
299 took the full preloading time and on 1st program change the respective
300 instrument was completely reloaded again.
301 - fixed handling of rapid bank select and program change messages
302 sent to the same sampler channel (patch from the Open Octave
303 project, slightly adjusted)
304 - fixed crash when trying to create an effect instance with controls
305 which min and/or max values depend on the sample rate

308 multiple paths (#165)
310 Version 1.0.0 (31 July 2009)
312 * packaging changes:
313 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

325 directory of liblinuxsampler dll (look in the same directory and one
326 directory above)
327 - configure script fix: removed unconditional use of SSE
328 - fixed building with sqlite installed in a non-standard directory
329 - when cross-compiling, don't try to create instruments.db
330 - fix for new mingw-w64 version, which has usleep
332 * general changes:
333 - bugfix: on some POSIX systems instrument editor plugins refused to
334 load as we used a non-portable Linux specific struct field
335 (fixes bug #70, patch by Ronald Baljeu)
336 - fixed endless loop which occured when loading an instrument editor
337 plugin DLL on Windows systems failed
338 - fixed memory leaks that occurred when liblinuxsampler was unloaded
339 - optimized the SynchronizedConfig class so it doesn't wait
340 unnecessarily long after an update
341 - added support for notifying instrument editors on note-on / note-off
342 events (e.g. to highlight the pressed keys on the virtual keyboard
343 of gigedit)
344 - added support for triggering notes by instrument editors (see above)
345 - be verbose on DLL load errors (on Linux)
346 - fixed di-harmonic triangle LFO implementation (this LFO implementation
347 is only used by very few systems, most pick the int math
348 implementation, which is usually faster)
349 - fixes for audio drivers with varying buffer sizes
350 - experimental support for running LinuxSampler as a DSSI, LV2 and
351 VST plugin
352 - notification events for stream/voice count statistics are now sent
353 only when there are actual changes
354 - added memory ordering constraints to improve stability on
355 multi-core and multi-cpu systems
356 - maximum voices and disk streams can now be altered at runtime
357 - fixed CPU feature detection on x86_64 (maybe fixes #108)
358 - automatic stacktrace mechanism is now turned off by default and can
359 be switched on by command line option "--stacktrace" (the automatic
360 stacktrace mechanism seems to be broken on most systems at the moment)
361 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
362 a pointer to the launched InstrumentEditor object
363 - added optional 3rd party user data parameter for following
364 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
365 InstrumentEditor::Launch(),
366 InstrumentManager::LaunchInstrumentEditor()
367 - theoretical fix: made SynchronizedConfig follow C++0x memory
368 model more strictly
369 - fixes for using large audio device buffers
370 - Windows: add the installation directory to the DLL search path
371 when loading an editor plugin (solves problems with VST and
372 gigedit on systems with other GTK versions installed)
374 * audio driver:
375 - removed the nonsense audio channel constraint (which was hard coded to
376 max. 100 audio channels) for most audio drivers
377 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
378 opposed to the LSCP specs
379 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
380 reflected the wrong value
381 - fixed a memory management bug in ASIO driver
382 - Makefile fix: JACK_CFLAGS wasn't used
383 - JACK: use jack_client_open instead of the deprecated
384 jack_client_new
385 - added (experimental) CoreAudio driver
386 - applied old fixes to the ASIO driver that were included in the
387 previous binary release but accidentally never committed to CVS
388 (fixes #117)

390 win64)
391 - VST: added support for sample rate and buffer size changes
392 - VST: close editor (Fantasia) when the VST is removed
393 - VST: avoid opening Fantasia more than once for each VST instance

397 stereo
398 - added channel routing, fxsends and midi maps to the settings
399 stored in the plugin state
400 - performance optimization of AudioChannel::MixTo() and
401 AudioChannel::CopyTo() methods using GCC vector exensions
402 (if available)
403 - ASIO fixes: avoid initializing the device twice, avoid throwing
404 exception when getting parameters from a disconnected device
406 * MIDI driver:
407 - added JACK MIDI driver
408 - dispatch bank select as ordinary CC as well, the user might seriously
409 want to (mis)use it for some purpose ("fixed" in all current MIDI
410 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
411 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
412 CoreMidi or AU
413 - fixed mingw-w64 compilation error in MME driver
414 - made program change handling in MIDI thread real-time safe by
415 moving the logic to a non-RT thread

418 * instruments database:
419 - avoid time consuming samples scanning when adding instruments
420 to the instruments database

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