  was not set or was set to zero

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

32 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
33 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
34 note (in this implementation of the sampler its simply hard routed to
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

179 - Listen to all interfaces on Mac OS X (INADDR_ANY)
180 - VST bugfix: If the host called resume() before and after
181 changing sample rate or block size, the number of channels was
182 incorrectly set to two. This caused silence in Cubase 5.
183 - save engine type (gig, sfz or sf2) in plugin state
184 - VST: when opening Fantasia, look for both 32 and 64 bit Java on
185 64 bit Windows
186 - AU: changed number of output channels from one stereo to 16
187 stereo

190 specified
192 * MIDI driver:
193 - ALSA MIDI driver supports now "NAME" device parameter, for overriding
194 the ALSA sequencer client name

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

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