* added command line option --exec-after-init

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

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

226 specified
228 * MIDI driver:
229 - ALSA MIDI driver supports now "NAME" device parameter, for overriding

277 - fixed crash which occurred when changing an already deployed sampler
278 channel to a different engine type
279 - fixed crash when deleting a sampler channel or changing engine
280 type while an instrument load was in progress
281 - bugfix: playing a note while changing the instrument could cause

283 - bugfix: calling SET VOICES (which Fantasia does on start and
284 refresh) could cause instruments to be unloaded
285 - Mac OS X: fixed name collision of enum in EffectControl and
286 wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
287 - Mac OS X: fixed hanging threads
288 - Windows: disabled the previous thread fix on non-Mac systems, as
289 it caused hanging threads on Windows
290 - Fixed possible crashes due to corrupted MIDI/audio device list
291 after MIDI/audio device creation failure
292 - When creating MIDI instrument map entries with "PERSISTENT" type, the
293 instruments were uselessly precached with zero samples, however it still
294 took the full preloading time and on 1st program change the respective
295 instrument was completely reloaded again.
296 - fixed handling of rapid bank select and program change messages
297 sent to the same sampler channel (patch from the Open Octave
298 project, slightly adjusted)
299 - fixed crash when trying to create an effect instance with controls
300 which min and/or max values depend on the sample rate
302 Version 1.0.0 (31 July 2009)
304 * packaging changes:
305 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
306 causing e.g. the libgig test to fail when
307 "./configure --disable-jack-driver" was used

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