* sfz engine: implemented automatic aliasing *ccN <-> *_onccN

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
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

178 incorrectly set to two. This caused silence in Cubase 5.
179 - save engine type (gig, sfz or sf2) in plugin state
180 - VST: when opening Fantasia, look for both 32 and 64 bit Java on
181 64 bit Windows

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

251 after MIDI/audio device creation failure
253 Version 1.0.0 (31 July 2009)
255 * packaging changes:
256 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
257 causing e.g. the libgig test to fail when
258 "./configure --disable-jack-driver" was used
259 (patch by Alexis Ballier)
260 - fixed compilation with gcc 4.3
261 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
262 - fixed configure so it detects x86_64 (#107)
263 - fixes for building with newer MinGW versions
264 - fix for building with bison 2.4 (#111)
265 - fixed building with libgig installed in a non-standard directory
266 - minor fix in configure for mmsystem.h detection on MinGW
267 - Windows: look for editor plugins and Fantasia using base
268 directory of liblinuxsampler dll (look in the same directory and one
269 directory above)
270 - configure script fix: removed unconditional use of SSE
271 - fixed building with sqlite installed in a non-standard directory
272 - when cross-compiling, don't try to create instruments.db
273 - fix for new mingw-w64 version, which has usleep
275 * general changes:
276 - bugfix: on some POSIX systems instrument editor plugins refused to
277 load as we used a non-portable Linux specific struct field
278 (fixes bug #70, patch by Ronald Baljeu)
279 - fixed endless loop which occured when loading an instrument editor
280 plugin DLL on Windows systems failed
281 - fixed memory leaks that occurred when liblinuxsampler was unloaded
282 - optimized the SynchronizedConfig class so it doesn't wait
283 unnecessarily long after an update
284 - added support for notifying instrument editors on note-on / note-off
285 events (e.g. to highlight the pressed keys on the virtual keyboard
286 of gigedit)
287 - added support for triggering notes by instrument editors (see above)
288 - be verbose on DLL load errors (on Linux)
289 - fixed di-harmonic triangle LFO implementation (this LFO implementation
290 is only used by very few systems, most pick the int math
291 implementation, which is usually faster)
292 - fixes for audio drivers with varying buffer sizes
293 - experimental support for running LinuxSampler as a DSSI, LV2 and
294 VST plugin
295 - notification events for stream/voice count statistics are now sent
296 only when there are actual changes
297 - added memory ordering constraints to improve stability on
298 multi-core and multi-cpu systems
299 - maximum voices and disk streams can now be altered at runtime
300 - fixed CPU feature detection on x86_64 (maybe fixes #108)
301 - automatic stacktrace mechanism is now turned off by default and can
302 be switched on by command line option "--stacktrace" (the automatic
303 stacktrace mechanism seems to be broken on most systems at the moment)
304 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
305 a pointer to the launched InstrumentEditor object
306 - added optional 3rd party user data parameter for following
307 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
308 InstrumentEditor::Launch(),
309 InstrumentManager::LaunchInstrumentEditor()
310 - theoretical fix: made SynchronizedConfig follow C++0x memory
311 model more strictly
312 - fixes for using large audio device buffers
313 - Windows: add the installation directory to the DLL search path
314 when loading an editor plugin (solves problems with VST and
315 gigedit on systems with other GTK versions installed)
317 * audio driver:
318 - removed the nonsense audio channel constraint (which was hard coded to
319 max. 100 audio channels) for most audio drivers
320 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
321 opposed to the LSCP specs
322 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
323 reflected the wrong value
324 - fixed a memory management bug in ASIO driver
325 - Makefile fix: JACK_CFLAGS wasn't used
326 - JACK: use jack_client_open instead of the deprecated
327 jack_client_new
328 - added (experimental) CoreAudio driver
329 - applied old fixes to the ASIO driver that were included in the
330 previous binary release but accidentally never committed to CVS
331 (fixes #117)
332 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
333 win64)
334 - VST: added support for sample rate and buffer size changes
335 - VST: close editor (Fantasia) when the VST is removed
336 - VST: avoid opening Fantasia more than once for each VST instance
337 - VST: export main function as "main" on Linux too (fix for
338 energyXT)
339 - VST: changed number of output channels from one stereo to 16
340 stereo
341 - added channel routing, fxsends and midi maps to the settings
342 stored in the plugin state
343 - performance optimization of AudioChannel::MixTo() and
344 AudioChannel::CopyTo() methods using GCC vector exensions
345 (if available)
346 - ASIO fixes: avoid initializing the device twice, avoid throwing
347 exception when getting parameters from a disconnected device
349 * MIDI driver:
350 - added JACK MIDI driver
351 - dispatch bank select as ordinary CC as well, the user might seriously
352 want to (mis)use it for some purpose ("fixed" in all current MIDI
353 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
354 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
355 CoreMidi or AU
356 - fixed mingw-w64 compilation error in MME driver
357 - made program change handling in MIDI thread real-time safe by
358 moving the logic to a non-RT thread
359 - fixed minor memory leak in ALSA driver
361 * instruments database:
362 - avoid time consuming samples scanning when adding instruments
363 to the instruments database
364 - added support for handling lost files in the instruments database
365 - Implemented option for adding instruments in separate directories
366 in the instruments database
367 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
368 - work-around for missing fnmatch function on Windows to make
369 instrument database compilable
370 - added instrument database support on Windows
371 works with both standalone mode and VST plugin.
372 the instruments DB file is located in
373 %USERPROFILE%\.linuxsampler\instruments.db which allows different
374 databases for each windows user
375 if no DB is present it automatically creates the .linuxsampler subdir
376 and then creates an empty DB
377 - fixed recursive import, which was broken on Windows
379 * Gigasampler format engine:
380 - fixed a memory leak that could happen when a channel was deleted
381 while notes were playing
382 - made it possible to load an instrument even if the audio thread
383 isn't running
384 - added partial support for the "Controller Triggered" MIDI rule,
385 enough for piano gigs with pedal noise samples
386 - minor fix: only mark FX sends as being modified if really the
387 respective FX send MIDI controller was used
388 - added support for GM global device volume SysEx message
389 (can be selected at compile time to either apply globally to the
390 whole sampler [default] or only to the sampler channels that are
391 connected to the respective MIDI input port the SysEx message arrived
392 on)
393 - bugfix: notes triggered at position 0 in the audio buffer were
394 sometimes wrongly killed in the same buffer, causing no sound to
395 be played
396 - added support for chromatic / drumkit mode Roland GS Sysex message
397 which is usally used to switch a part between chromatic sounds and
398 drumkit sounds (as opposed to their common default setting of MIDI
399 part 10 being a drumkit part and all other ones chromatic parts), in
400 LS however one can switch between the first 16 MIDI instrument maps
401 defined for the sampler
402 - made it possible to create multiple sample channels even if the
403 audio thread isn't running
404 - fixed crash when removing channel with active voices (#116)
405 - bugfix: on sample reference changes (instrument editor), only
406 un-cache the respective sample if it's really not used by any
407 sampler engine anymore
408 - re-cache samples in case they were changed by an instrument editor,
409 e.g. when a sample was added while playing (#82)
410 - fixed hanging notes which occured when note-off event had the exact
411 same time stamp as the voice's note-on event and occured both in the
412 same audio fragment cycle (fixes bug #112)
413 - added support for the "fine tune" and "pitch bend range"
414 instrument-level gig parameters
415 - fixed minor artifacts in pitch bend handling
416 - added support for GS Reset SysEx message
417 - allow gig files to use unlimited downward pitch shifting
418 - added a limit check for upward pitch shifting
419 - bugfix: sometimes, when playing a note twice fast, the second
420 note was silent
421 - fixed crash happening when a pitch bend event arrived at the
422 same time a new instrument was loading
424 * LSCP server:
425 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
426 react on MIDI data arriving on certain sampler channels (so far only
427 Note-On and Note-Off events are sent via this LSCP event)
428 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
429 react on MIDI data arriving on certain MIDI input devices (so far only
430 Note-On and Note-Off events are sent via this LSCP event)
431 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
433 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
434 frontends to send MIDI messages to specific sampler channel
435 - added two additional fields to GET FILE INSTRUMENT INFO command -
437 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
438 was incorrect
439 - Optimized the retrieval of the MIDI instrument mappings
440 - added new LSCP command "SET VOICES" to globally alter the maximum
441 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
442 be triggered respectively
443 - added new LSCP command "SET STREAMS" to globally alter the maximum
444 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
445 which will be triggered respectively
446 - bugfix: retry if "select" returns EINTR (this fixes a crash when
447 a gigedit file dialog is opened)
448 - close all connections when LSCPServer is deleted
449 - hard close of all sockets on exit
450 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
451 driver
453 * Bug fixes:
454 - fixed a crash which occurs when removing a sampler channel waiting
455 to start instrument loading after another channel
456 - fixed a crash which occurs when removing a sampler channel with
457 instrument loading in progress (bug #113)
458 - fixed termination caused by uncaught exception when adding MIDI
459 instrument with PERSISTENT load mode
460 - fixed possible iterator invalidations when resetting the sampler
461 - fixed memory leaks when issuing the following LSCP commands:
466 - fixed possible compilation error when sqlite is not present
467 - fixed orphaned pointers when setting maximum voices limit (bug #118)
468 - fixed crash when changing the audio output device of a sampler
469 channel with loaded instrument and start playing notes
470 - fixed endless loop in Engine::SuspendAll() (bug #120)
471 - fixed a low-level atomic load function that was broken on 64-bit
472 PowerPC, which probably could cause crashes on that platform
473 - fixed a memory management error which could cause a crash when a
474 plugin was unloaded
475 - bugfix: two private structs had the same name, which could cause
476 problems if the linker chose the wrong constructor
477 - fixed low-level ConditionServer usage bug that caused lockups on
478 Windows
481 Version 0.5.1 (6 December 2007)
483 * packaging changes:
484 - added autoconf checks for pthread library
485 - added autoconf check for pthread bug found on certain NPTL-enabled
486 glibc versions (see Gentoo bug report #194076)
487 - added autoconf checks for MS Windows
489 * general changes:
490 - bugfix: the thread used by an editor plugin didn't die when the
491 editor closed
492 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
493 out all the space. operator--() did not apply size_mask after
494 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
495 order to avoid problems with the _NonVolatileReader functions.
496 - bugfix: Stream.h: added a missing divide by BytesPerSample in
497 GetWriteSpace(). Since this function is currently only used in
498 the stream's qsort() compare function, it didn't trigger any
499 bugs.
500 - Resampler.h, Synthesizer.h: cubic interpolation now works in
501 24bit mode too. Faster method to read 24bit words on little
502 endian machines (x86): replaced 3 byte reads + shifts with a 1
503 unaligned 32bit read and shift
504 - experimental support for MS Windows (MIDI input via MME, AUDIO
505 output via ASIO)
506 - made handling of SIGINT signal (Ctrl-C) a bit more robust
507 - support for monitoring the total number of active disk streams
508 (new LSCP commands: GET TOTAL_STREAM_COUNT,
511 * AUDIO driver:
512 - added Windows ASIO low latency audio driver
514 * MIDI driver:
515 - added MME Windows MIDI driver
517 * LSCP server:
518 - added support for Windows style path / filenames, however with
519 forward slash path separators instead of backslash
520 (i.e. "C:/foo/bar.gig")
521 - allow naughty liblscp to send non-string device parameters within
522 apostrophes as well
523 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
524 "LIST FILE INSTRUMENTS <file>" and
525 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
526 about an arbitrary instrument file on the system where the sampler is
527 running on
529 Version 0.5.0 (15 October 2007)
531 * packaging changes:
532 - config.h is not going to be installed along with liblinuxsampler's
533 API header files anymore
534 - only the API relevant header (and source) files will be exported to
535 the Doxygen API documentation (explicitly listed in Doxyfile.in)
536 - added completely new XCode project files for Mac OSX which is now
537 capable to execute our autoconf environment, thus no need anymore
538 to maintain the compile time configuration file (osx/version.h) for
539 OSX manually (patch by Toshi Nagata)
540 - fixed buggy boolean --enable-foo / --disable-foo configure script
541 parameters
542 - global.h now only covers global definitions that are needed for the
543 C++ API header files, all implementation internal global definitions
544 are now in global_private.h
545 - atomic.h is not exposed to the C++ API anymore
546 - no need to include config.h anymore for using LS's API header files
547 - fixed warnings in API doc generation
549 * general changes:
550 - replaced the old, confusing MIDI program change mechanism by a
551 flexible MIDI instrument mapper which allows to map arbitrary
552 (MIDI bank, MIDI program) pairs with arbitrary
553 (engine type, instrument file, file index) triplets which will be
554 loaded on the respective channel when such MIDI program change
555 messages arrive, beside that, each entry allows to define a life-time
556 strategy for the instrument, so the user can define whether the
557 instrument should i.e. be permanently loaded (to be able to switch
558 quickly among sounds) or i.e. loaded just on demand when the
559 respective program change arrives (to safe RAM space), as well as a
560 global volume factor for each entry, so the user can adjust the volume
561 dynamic of his mapped instrument collection without having to modify
562 the instrument files, also one can manage arbitrary amount of such
563 MIDI instrument maps and assign each sampler channel individually
564 a certain map, so that i.e. separation of normal instruments and
565 drumkits is possible
566 - new notification events for tracking changes to audio/MIDI devices,
567 MIDI instrument maps, MIDI instruments, FX sends, global volume.
568 - sampler was limited to load max. 200 instruments in the background
569 due to a constant size RingBuffer FIFO which is now replaced by a
570 dynamic (unlimited) size std::list FIFO
571 - added FX sends, these allow to route audio signals to arbitrary audio
572 output channels for being processed by external effect processors
573 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
574 controllers
575 - global (sampler wide) volume can now be controlled at runtime
576 - Implemented new, improved notification system
577 - fixed compilation errors regarding OSX
578 (patch by Toshi Nagata)
579 - implemented instruments database
580 - added support for escape sequences to the instruments database
581 - added highly experimental support for on-the-fly instrument editing
582 within the sampler's process (by using instrument editor plugins),
583 you'll notice the new "Registered instrument editors:" message on
584 startup, added a new LSCP command:
585 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
586 to spawn a matching instrument editor for the instrument on the
587 given sampler channel, the plugin path can be overridden at compile
588 time with ./configure --enable-plugin-dir=/some/dir
589 - added experimental code for synchronizing instrument editors hosted
590 in the sampler's process to safely edit instruments while playing
591 without a crash (hopefully) by either suspending single regions
592 wherever possible or if unavoidable whole engine(s)
593 - fixed several issues in fundamental "Thread" class: set scheduling
594 policy and priority on thread level, set a minimum stack size for
595 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
596 threads simply inherited properties of starting thread instead of
597 setting their own policy and priority
598 - minor fix in our automatic stack trace mechanism on crashes, the
599 main process did not wait for the stack trace process to finish
600 its output
601 - fixed some minor memory leaks
602 - reenabled assembly features support, at the moment only for
603 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
604 - minor assembly fix in x86 features detection (don't use the PIC
605 register, to avoid relocations in the text segment at runtime)
606 - POSIX callback functions of Thread.h are hidden
608 * MIDI driver:
609 - dispatch bank select (MSB and LSB) messages
611 * audio driver:
612 - the ALSA audio output driver parameters now reflect the correct
613 parameter value ranges for the respective selected sound card
614 (patch by Till Wimmer, a bit fixed and extended)
616 * Gigasampler format engine:
617 - if a filter is used and EG2 finishes before EG1, let the voice
618 die when EG2 has finished (this fixes a problem with clicks and
619 voice starvation for some gigs)
620 - playback is no longer disabled during instrument loading
621 - all notes playing on a channel that changes its instrument keep
622 playing with the old instrument until they get a note off
623 command
624 - EG fix: a release value of zero could cause noises or crash
625 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
626 - EG fine tuning: when attack is zero the EG starts at a level
627 above max sustain level, which means that there is a decay phase
628 even if sustain is 100%
629 - more EG fixes: the level could sometimes go below zero and cause
630 noises or crashes
631 - minor fix of EGDecay (patch by Toshi Nagata)
632 - fixed compiler error when --enable-override-filter-type was
633 supplied to the configure script (fixes #46)
634 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
635 instead of a fix value
636 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
637 127 (solo mode) only kill voices if the respective mode really
638 changed
640 * LSCP server:
641 - fixed compile time error for old Bison versions
642 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
643 - parser now supports extended ASCII character set
644 (up to ASCII code 255, i.e. includes now umlauts and accents)
645 - filename arguments in LSCP commands now allow to use escape
646 sequences, that is directly literal as one of: \', \", \\, \n, \r,
647 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
648 code value like \xf2) (fixes bug #24)
649 - the following LSCP commands now also support escape sequences for at
650 least one of their text-based parameters (i.e. name, description):
657 - returns verbose syntax errors (line and column where syntax error
658 occured, the unexpected character and the actually expected, possible
659 character(s), the latter only if less than 5 possibilities)
660 - made sure that LSCP syntax is not affected by gigedit locale
661 settings
662 - bugfix regarding strings parameter lists: all comma separated lists
663 of strings were treated as being one string containing commas
664 (fixes #57)
666 * Bug fixes:
667 - fixed crash occurring on certain LSCP scripts (Bug 39)
668 - another thread safety fix for lscp "load engine" and "set
669 channel audio output device"
670 - fixed a crash which occurs when reassigning the same engine
671 on a sampler channel with connected MIDI device
672 - fixed a crash which occurs when changing the number of ports of a MIDI
673 device connected to a sampler channel to number less then or equal
674 to the index of the port to which the sampler channel is connected.
675 - The previous bindings were not been disconnected when altering
676 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
677 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
678 - The active stream/voice count statistic was incorrect.
679 - notification events were not been sent for some sampler
680 channel changes
681 - added default min and max values to restrict the number of allowed
682 audio output channels and MIDI input ports
683 - the connection to the PCM interface is now closed when destroying
684 an audio output device
685 - files with slash in their path or filename could not be loaded
687 * test cases:
688 - updated and fixed (haven't been touched in a while)
690 Version 0.4.0 (24 November 2006)
692 * packaging changes:
693 - changed deprecated copyright attribute to license; added ldconfig
694 to post-(un)install steps; added devel package for liblinuxsampler;
695 to linuxsampler.spec (RPM)
696 - install necessary development header files for allowing 3rd party
697 applications to link against liblinuxsampler
698 - liblinuxsampler's API documentation can be generated with 'make docs'
699 (Doxygen required)
700 - added benchmark to automatically detect the best triangle LFO
701 implementation (currently either an integer math solution or a
702 di-harmonic approximation), automatic detection can be overriden
703 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
704 configure script argument though (mandatory for cross-compilation)
705 - do not automatically pick optimized gcc flags if the user already
706 provided some on his own (as CXXFLAGS)
707 - added compile time option to disable processing of All-Notes-Off MIDI
708 messages
709 - added compile time options to allow disabling the various audio and
710 MIDI drivers
711 - fixed automatic GCC CPU switch detection on PPC
712 (patch by Ebrahim Mayat)
714 * Gigasampler format engine:
715 - extensive synthesis optimization
716 (reimplementation of EGs and LFO(s), removed synthesis parameter
717 prerendering and the synthesis parameter matrix in general, splitting
718 each audio fragment into subfragments now where each subfragment uses
719 constant pitch and filter coefficients. The volume coefficient is
720 linearly interpolated inside a subfragment, unless
721 --disable-interpolate-volume is set.)
722 - fine tuning of the EG modulation parameters
723 - improved filter cutoff calculation by adding support for the
724 following gig parameters: Cutoff freq (used when no cutoff
725 controller is defined), Control invert, Minimum cutoff, Velocity
726 curve and Velocity range. The keyboard tracking now scales
727 cutoff frequency instead of resonance.
728 - added support for gig parameter Resonance.
729 - fixed bug in sysex handling (patch by Juan Linietsky)
730 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
731 which can be overridden with --enable-global-attenuation
732 - EG fixes: made the length of "attack hold" stage more
733 accurate. Release stage can now start before attack stage
734 ends. Cancel release didn't work when sustain was zero. Attack
735 time now has a minimal value to prevent clicks.
736 - fixed pitch changes larger than one octave
737 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
738 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
739 all modes can be altered via standard GM messages, that is CC5 for
740 altering portamento time, CC65 for enabling / disabling portamento
741 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
742 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
743 parameter) and crossfade
744 - added support for the "attenuation controller threshold" gig
745 parameter
746 - added smoothing of volume changes caused by control change
747 messages
748 - sample loop parameters are now taken from the DimensionRegion
749 instead of the wave chunk
750 - fixed keyswitching for v3 gigs with a number of keyswitch splits
751 not equal to a power of two
752 - reimplementation of the filter algorithm. The new filter is more
753 accurate and supports all gig filter types, including bandreject
754 and lowpass turbo.
755 - real support for 24 bit samples - samples are not truncated to
756 16 bits anymore
757 - support for aftertouch (channel pressure, not polyphonic
758 aftertouch)
759 - LFO1 behaviour fixed (dampening from max volume instead of
760 amplifying from 0)
762 * LSCP server:
763 - fixed application exit on broken pipe error (fixes bug #20)
764 - fixed the notification messages delay due to lack of
765 network activity (fixes bug #26)
766 - fixed parser bug which occured on space(s) within device parameters
769 * audio driver:
770 - added aRts audio output driver (by no means RT safe)
772 * MIDI driver:
773 - fixed legacy sysex code which caused dispatching of MIDI SysEx
774 messages several times instead of once
775 - API extension for MIDI drivers which already supply exact time stamps
776 for events (i.e. for offline rendering based MIDI drivers)
777 - added checks for bad MIDI data
779 * linuxsampler application:
780 - show available sampler engine types on startup
782 * general changes:
783 - support for muting sampler channels and solo mode of the same, two new
784 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
785 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
786 introduced for this, the behavior is the same like on a mixer console
787 (patch by Grigor Iliev, a bit adjusted). Also added configure option
788 --enable-process-muted-channels which can be used to enable the
789 processing of muted channels.
790 - support for sostenuto pedal
791 - support for monitoring the total number of active voices
794 - fixed some memory management errors
795 - fixed some concurrency problems that could lead to crashes when
796 LSCP commands were executed
797 - fixed crash when instrument loading failed previously on the same
798 sampler channel (fixes bug #36)
800 Version 0.3.3 (15 July 2005)
802 * packaging changes:
803 - fixed compilation with gcc 4.0
805 * Gigasampler format engine:
806 - LFO preprocessing was performed even though the respective LFO was
807 disabled by the instrument patch (minor efficiency fix)
808 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
809 for volume ramp downs in the same fragment (needed for current voice
810 stealing implementation) then simply inform the user with a warning
811 about possible click sounds and reduce the volume ramp down
812 appropriately instead of cancelling the audio device connection
814 Version 0.3.2 (24 June 2005)
816 * packaging changes:
817 - updated autotools build files to compile on OS X
818 (conditional compilation of CoreMIDI and MidiShare drivers)
819 - hand-crafted assembly optimization code can be disabled with
820 './configure --disable-asm' (definitely not recommended)
821 - fixed 'make dist' rule to include all necessary files
822 - require automake (>= 1.5) for 'make -f Makefile.cvs'
823 (due to 'dist-bzip2' automake option)
825 * Gigasampler format engine:
826 - support for the gig parameters for "release velocity response" curves
827 - fine tuning of the EGADSR envelope
828 - volume of release triggered samples now depends on note-on velocity,
829 note length and gig parameter "release trigger decay" instead of
830 note-off velocity.
831 - revised voice stealing
832 (fixes crash and endless loop caused by voice stealing)
833 - don't reset scale tuning on instrument or audio output device change
834 - handle key group conflicts right at the beginning of each fragment
835 instead of when the respective voice is actually launched
836 (fixes undefined behavior if stolen voices belonged to a key group -
837 this case was followed by a "killed voice survived" error message)
838 - fixed minor issue with null/silence samples
839 (those stole voices even though they don't need a voice at all which
840 resulted in "voice stealing didn't work out" messages)
841 - don't reset volume, pan, pitch and MIDI controller values on
842 instrument or audio output device change
844 * LSCP server:
845 - fixed some crashes (patch by Grigor Iliev, fixes #19)
846 - fixed LSCP event "CHANNEL_INFO" notification
847 (e.g. did not notify on volume changes or MIDI program change events)
849 * linuxsampler application:
850 - added command line parameters --lscp-addr and --lscp-port to override
851 default IP address and port of LSCP server
853 Version 0.3.1 (24 May 2005)
855 * initial release
