1 Version CVS HEAD (?)
3 * plugin changes:
4 - LV2 Persist + Files 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

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

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

243 * Bug fixes:
244 - Fixed crash which may occur when MIDI key + transpose is out of range
245 - minor valgrind fixes
246 - fixed crash which occurred when changing an already deployed sampler
247 channel to a different engine type
248 - fixed crash when deleting a sampler channel or changing engine
249 type while an instrument load was in progress
250 - bugfix: playing a note while changing the instrument could cause
251 a crash, or give "Handing back unknown region" error messages
252 - bugfix: calling SET VOICES (which Fantasia does on start and
253 refresh) could cause instruments to be unloaded
254 - Mac OS X: fixed name collision of enum in EffectControl and
255 wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
256 - Mac OS X: fixed hanging threads
257 - Windows: disabled the previous thread fix on non-Mac systems, as
258 it caused hanging threads on Windows

260 after MIDI/audio device creation failure
262 Version 1.0.0 (31 July 2009)
264 * packaging changes:
265 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
266 causing e.g. the libgig test to fail when
267 "./configure --disable-jack-driver" was used
268 (patch by Alexis Ballier)
269 - fixed compilation with gcc 4.3
270 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)

274 - fixed building with libgig installed in a non-standard directory
275 - minor fix in configure for mmsystem.h detection on MinGW
276 - Windows: look for editor plugins and Fantasia using base
277 directory of liblinuxsampler dll (look in the same directory and one
278 directory above)
279 - configure script fix: removed unconditional use of SSE
280 - fixed building with sqlite installed in a non-standard directory
281 - when cross-compiling, don't try to create instruments.db
282 - fix for new mingw-w64 version, which has usleep
284 * general changes:
285 - bugfix: on some POSIX systems instrument editor plugins refused to
286 load as we used a non-portable Linux specific struct field
287 (fixes bug #70, patch by Ronald Baljeu)
288 - fixed endless loop which occured when loading an instrument editor
289 plugin DLL on Windows systems failed
290 - fixed memory leaks that occurred when liblinuxsampler was unloaded
291 - optimized the SynchronizedConfig class so it doesn't wait
292 unnecessarily long after an update
293 - added support for notifying instrument editors on note-on / note-off
294 events (e.g. to highlight the pressed keys on the virtual keyboard
295 of gigedit)
296 - added support for triggering notes by instrument editors (see above)
297 - be verbose on DLL load errors (on Linux)
298 - fixed di-harmonic triangle LFO implementation (this LFO implementation
299 is only used by very few systems, most pick the int math
300 implementation, which is usually faster)
301 - fixes for audio drivers with varying buffer sizes
302 - experimental support for running LinuxSampler as a DSSI, LV2 and
303 VST plugin
304 - notification events for stream/voice count statistics are now sent
305 only when there are actual changes

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