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

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
295 - Fixed possible crashes due to corrupted MIDI/audio device list
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
306 - fixed bug #162
308 Version 1.0.0 (31 July 2009)
310 * packaging changes:
311 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
312 causing e.g. the libgig test to fail when
313 "./configure --disable-jack-driver" was used

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

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

393 energyXT)
394 - VST: changed number of output channels from one stereo to 16
395 stereo
396 - added channel routing, fxsends and midi maps to the settings
397 stored in the plugin state
398 - performance optimization of AudioChannel::MixTo() and
399 AudioChannel::CopyTo() methods using GCC vector exensions
400 (if available)
401 - ASIO fixes: avoid initializing the device twice, avoid throwing
402 exception when getting parameters from a disconnected device
404 * MIDI driver:
405 - added JACK MIDI driver
406 - dispatch bank select as ordinary CC as well, the user might seriously
407 want to (mis)use it for some purpose ("fixed" in all current MIDI
408 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
409 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
410 CoreMidi or AU
411 - fixed mingw-w64 compilation error in MME driver
412 - made program change handling in MIDI thread real-time safe by
413 moving the logic to a non-RT thread
414 - fixed minor memory leak in ALSA driver
416 * instruments database:
417 - avoid time consuming samples scanning when adding instruments
418 to the instruments database

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