21
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

164 * MIDI driver:
165 - ALSA MIDI driver supports now "NAME" device parameter, for overriding
166 the ALSA sequencer client name

214 channel to a different engine type
215 - fixed crash when deleting a sampler channel or changing engine
216 type while an instrument load was in progress
217 - bugfix: playing a note while changing the instrument could cause
218 a crash, or give "Handing back unknown region" error messages
219 - bugfix: calling SET VOICES (which Fantasia does on start and
220 refresh) could cause instruments to be unloaded
221 - Mac OS X: fixed name collision of enum in EffectControl and

228
229 Version 1.0.0 (31 July 2009)
230
231 * packaging changes:
232 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
233 causing e.g. the libgig test to fail when
234 "./configure --disable-jack-driver" was used
235 (patch by Alexis Ballier)
236 - fixed compilation with gcc 4.3
237 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
238 - fixed configure so it detects x86_64 (#107)
239 - fixes for building with newer MinGW versions
240 - fix for building with bison 2.4 (#111)
241 - fixed building with libgig installed in a non-standard directory
242 - minor fix in configure for mmsystem.h detection on MinGW
243 - Windows: look for editor plugins and Fantasia using base
244 directory of liblinuxsampler dll (look in the same directory and one
245 directory above)
246 - configure script fix: removed unconditional use of SSE
247 - fixed building with sqlite installed in a non-standard directory
248 - when cross-compiling, don't try to create instruments.db
249 - fix for new mingw-w64 version, which has usleep
250
251 * general changes:
252 - bugfix: on some POSIX systems instrument editor plugins refused to
253 load as we used a non-portable Linux specific struct field
254 (fixes bug #70, patch by Ronald Baljeu)
255 - fixed endless loop which occured when loading an instrument editor
256 plugin DLL on Windows systems failed
257 - fixed memory leaks that occurred when liblinuxsampler was unloaded
258 - optimized the SynchronizedConfig class so it doesn't wait
259 unnecessarily long after an update
260 - added support for notifying instrument editors on note-on / note-off
261 events (e.g. to highlight the pressed keys on the virtual keyboard
262 of gigedit)
263 - added support for triggering notes by instrument editors (see above)
264 - be verbose on DLL load errors (on Linux)
265 - fixed di-harmonic triangle LFO implementation (this LFO implementation
266 is only used by very few systems, most pick the int math
267 implementation, which is usually faster)
268 - fixes for audio drivers with varying buffer sizes
269 - experimental support for running LinuxSampler as a DSSI, LV2 and
270 VST plugin
271 - notification events for stream/voice count statistics are now sent
272 only when there are actual changes
273 - added memory ordering constraints to improve stability on
274 multi-core and multi-cpu systems
275 - maximum voices and disk streams can now be altered at runtime
276 - fixed CPU feature detection on x86_64 (maybe fixes #108)
277 - automatic stacktrace mechanism is now turned off by default and can
278 be switched on by command line option "--stacktrace" (the automatic
279 stacktrace mechanism seems to be broken on most systems at the moment)
280 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
281 a pointer to the launched InstrumentEditor object
282 - added optional 3rd party user data parameter for following
283 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
284 InstrumentEditor::Launch(),
285 InstrumentManager::LaunchInstrumentEditor()
286 - theoretical fix: made SynchronizedConfig follow C++0x memory
287 model more strictly
288 - fixes for using large audio device buffers
289 - Windows: add the installation directory to the DLL search path
290 when loading an editor plugin (solves problems with VST and
291 gigedit on systems with other GTK versions installed)
292
293 * audio driver:
294 - removed the nonsense audio channel constraint (which was hard coded to
295 max. 100 audio channels) for most audio drivers
296 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
297 opposed to the LSCP specs
298 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
299 reflected the wrong value
300 - fixed a memory management bug in ASIO driver
301 - Makefile fix: JACK_CFLAGS wasn't used
302 - JACK: use jack_client_open instead of the deprecated
303 jack_client_new
304 - added (experimental) CoreAudio driver
305 - applied old fixes to the ASIO driver that were included in the
306 previous binary release but accidentally never committed to CVS
307 (fixes #117)
308 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
309 win64)
310 - VST: added support for sample rate and buffer size changes
311 - VST: close editor (Fantasia) when the VST is removed
312 - VST: avoid opening Fantasia more than once for each VST instance
313 - VST: export main function as "main" on Linux too (fix for
314 energyXT)
315 - VST: changed number of output channels from one stereo to 16
316 stereo
317 - added channel routing, fxsends and midi maps to the settings
318 stored in the plugin state
319 - performance optimization of AudioChannel::MixTo() and
320 AudioChannel::CopyTo() methods using GCC vector exensions
321 (if available)
322 - ASIO fixes: avoid initializing the device twice, avoid throwing
323 exception when getting parameters from a disconnected device
324
325 * MIDI driver:
326 - added JACK MIDI driver
327 - dispatch bank select as ordinary CC as well, the user might seriously
328 want to (mis)use it for some purpose ("fixed" in all current MIDI
329 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
330 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
331 CoreMidi or AU
332 - fixed mingw-w64 compilation error in MME driver
333 - made program change handling in MIDI thread real-time safe by
334 moving the logic to a non-RT thread
335 - fixed minor memory leak in ALSA driver
336
337 * instruments database:
338 - avoid time consuming samples scanning when adding instruments
339 to the instruments database
340 - added support for handling lost files in the instruments database
341 - Implemented option for adding instruments in separate directories
342 in the instruments database
343 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
344 - work-around for missing fnmatch function on Windows to make
345 instrument database compilable
346 - added instrument database support on Windows
347 works with both standalone mode and VST plugin.
348 the instruments DB file is located in
349 %USERPROFILE%\.linuxsampler\instruments.db which allows different
350 databases for each windows user
351 if no DB is present it automatically creates the .linuxsampler subdir
352 and then creates an empty DB
353 - fixed recursive import, which was broken on Windows
354
355 * Gigasampler format engine:
356 - fixed a memory leak that could happen when a channel was deleted
357 while notes were playing
358 - made it possible to load an instrument even if the audio thread
359 isn't running
360 - added partial support for the "Controller Triggered" MIDI rule,
361 enough for piano gigs with pedal noise samples
362 - minor fix: only mark FX sends as being modified if really the
363 respective FX send MIDI controller was used
364 - added support for GM global device volume SysEx message
365 (can be selected at compile time to either apply globally to the
366 whole sampler [default] or only to the sampler channels that are
367 connected to the respective MIDI input port the SysEx message arrived
368 on)
369 - bugfix: notes triggered at position 0 in the audio buffer were
370 sometimes wrongly killed in the same buffer, causing no sound to
371 be played
372 - added support for chromatic / drumkit mode Roland GS Sysex message
373 which is usally used to switch a part between chromatic sounds and
374 drumkit sounds (as opposed to their common default setting of MIDI
375 part 10 being a drumkit part and all other ones chromatic parts), in
376 LS however one can switch between the first 16 MIDI instrument maps
377 defined for the sampler
378 - made it possible to create multiple sample channels even if the
379 audio thread isn't running
380 - fixed crash when removing channel with active voices (#116)
381 - bugfix: on sample reference changes (instrument editor), only
382 un-cache the respective sample if it's really not used by any
383 sampler engine anymore
384 - re-cache samples in case they were changed by an instrument editor,
385 e.g. when a sample was added while playing (#82)
386 - fixed hanging notes which occured when note-off event had the exact
387 same time stamp as the voice's note-on event and occured both in the
388 same audio fragment cycle (fixes bug #112)
389 - added support for the "fine tune" and "pitch bend range"
390 instrument-level gig parameters
391 - fixed minor artifacts in pitch bend handling
392 - added support for GS Reset SysEx message
393 - allow gig files to use unlimited downward pitch shifting
394 - added a limit check for upward pitch shifting
395 - bugfix: sometimes, when playing a note twice fast, the second
396 note was silent
397 - fixed crash happening when a pitch bend event arrived at the
398 same time a new instrument was loading
399
400 * LSCP server:
401 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
402 react on MIDI data arriving on certain sampler channels (so far only
403 Note-On and Note-Off events are sent via this LSCP event)
404 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
405 react on MIDI data arriving on certain MIDI input devices (so far only
406 Note-On and Note-Off events are sent via this LSCP event)
407 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
408 SET DB_INSTRUMENT FILE_PATH
409 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
410 frontends to send MIDI messages to specific sampler channel
411 - added two additional fields to GET FILE INSTRUMENT INFO command -
412 KEY_BINDINGS and KEYSWITCH_BINDINGS
413 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
414 was incorrect
415 - Optimized the retrieval of the MIDI instrument mappings
416 - added new LSCP command "SET VOICES" to globally alter the maximum
417 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
418 be triggered respectively
419 - added new LSCP command "SET STREAMS" to globally alter the maximum
420 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
421 which will be triggered respectively
422 - bugfix: retry if "select" returns EINTR (this fixes a crash when
423 a gigedit file dialog is opened)
424 - close all connections when LSCPServer is deleted
425 - hard close of all sockets on exit
426 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
427 driver
428
429 * Bug fixes:
430 - fixed a crash which occurs when removing a sampler channel waiting
431 to start instrument loading after another channel
432 - fixed a crash which occurs when removing a sampler channel with
433 instrument loading in progress (bug #113)
434 - fixed termination caused by uncaught exception when adding MIDI
435 instrument with PERSISTENT load mode
436 - fixed possible iterator invalidations when resetting the sampler
437 - fixed memory leaks when issuing the following LSCP commands:
438 GET AUDIO_OUTPUT_DRIVER INFO
439 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
440 GET MIDI_INPUT_DRIVER INFO
441 GET MIDI_INPUT_DRIVER_PARAMETER INFO
442 - fixed possible compilation error when sqlite is not present
443 - fixed orphaned pointers when setting maximum voices limit (bug #118)
444 - fixed crash when changing the audio output device of a sampler
445 channel with loaded instrument and start playing notes
446 - fixed endless loop in Engine::SuspendAll() (bug #120)
447 - fixed a low-level atomic load function that was broken on 64-bit
448 PowerPC, which probably could cause crashes on that platform
449 - fixed a memory management error which could cause a crash when a
450 plugin was unloaded
451 - bugfix: two private structs had the same name, which could cause
452 problems if the linker chose the wrong constructor
453 - fixed low-level ConditionServer usage bug that caused lockups on
454 Windows
455
456
457 Version 0.5.1 (6 December 2007)
458
459 * packaging changes:
460 - added autoconf checks for pthread library
461 - added autoconf check for pthread bug found on certain NPTL-enabled
462 glibc versions (see Gentoo bug report #194076)

464
465 * general changes:
466 - bugfix: the thread used by an editor plugin didn't die when the
467 editor closed
468 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
469 out all the space. operator--() did not apply size_mask after
470 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
471 order to avoid problems with the _NonVolatileReader functions.
472 - bugfix: Stream.h: added a missing divide by BytesPerSample in
473 GetWriteSpace(). Since this function is currently only used in
474 the stream's qsort() compare function, it didn't trigger any
475 bugs.
476 - Resampler.h, Synthesizer.h: cubic interpolation now works in
477 24bit mode too. Faster method to read 24bit words on little
478 endian machines (x86): replaced 3 byte reads + shifts with a 1
479 unaligned 32bit read and shift
480 - experimental support for MS Windows (MIDI input via MME, AUDIO
481 output via ASIO)
482 - made handling of SIGINT signal (Ctrl-C) a bit more robust
483 - support for monitoring the total number of active disk streams
484 (new LSCP commands: GET TOTAL_STREAM_COUNT,
485 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
486
487 * AUDIO driver:
488 - added Windows ASIO low latency audio driver
489
490 * MIDI driver:
491 - added MME Windows MIDI driver
492
493 * LSCP server:
494 - added support for Windows style path / filenames, however with
495 forward slash path separators instead of backslash
496 (i.e. "C:/foo/bar.gig")
497 - allow naughty liblscp to send non-string device parameters within
498 apostrophes as well
499 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
500 "LIST FILE INSTRUMENTS <file>" and
501 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
502 about an arbitrary instrument file on the system where the sampler is
503 running on
504
505 Version 0.5.0 (15 October 2007)
506
507 * packaging changes:
508 - config.h is not going to be installed along with liblinuxsampler's
509 API header files anymore
510 - only the API relevant header (and source) files will be exported to
511 the Doxygen API documentation (explicitly listed in Doxyfile.in)
512 - added completely new XCode project files for Mac OSX which is now
513 capable to execute our autoconf environment, thus no need anymore
514 to maintain the compile time configuration file (osx/version.h) for
515 OSX manually (patch by Toshi Nagata)
516 - fixed buggy boolean --enable-foo / --disable-foo configure script
517 parameters
518 - global.h now only covers global definitions that are needed for the
519 C++ API header files, all implementation internal global definitions
520 are now in global_private.h
521 - atomic.h is not exposed to the C++ API anymore
522 - no need to include config.h anymore for using LS's API header files
523 - fixed warnings in API doc generation
524
525 * general changes:
526 - replaced the old, confusing MIDI program change mechanism by a
527 flexible MIDI instrument mapper which allows to map arbitrary
528 (MIDI bank, MIDI program) pairs with arbitrary
529 (engine type, instrument file, file index) triplets which will be
530 loaded on the respective channel when such MIDI program change
531 messages arrive, beside that, each entry allows to define a life-time
532 strategy for the instrument, so the user can define whether the
533 instrument should i.e. be permanently loaded (to be able to switch
534 quickly among sounds) or i.e. loaded just on demand when the
535 respective program change arrives (to safe RAM space), as well as a
536 global volume factor for each entry, so the user can adjust the volume
537 dynamic of his mapped instrument collection without having to modify
538 the instrument files, also one can manage arbitrary amount of such
539 MIDI instrument maps and assign each sampler channel individually
540 a certain map, so that i.e. separation of normal instruments and
541 drumkits is possible
542 - new notification events for tracking changes to audio/MIDI devices,
543 MIDI instrument maps, MIDI instruments, FX sends, global volume.
544 - sampler was limited to load max. 200 instruments in the background
545 due to a constant size RingBuffer FIFO which is now replaced by a
546 dynamic (unlimited) size std::list FIFO
547 - added FX sends, these allow to route audio signals to arbitrary audio
548 output channels for being processed by external effect processors
549 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
550 controllers
551 - global (sampler wide) volume can now be controlled at runtime
552 - Implemented new, improved notification system
553 - fixed compilation errors regarding OSX
554 (patch by Toshi Nagata)
555 - implemented instruments database
556 - added support for escape sequences to the instruments database
557 - added highly experimental support for on-the-fly instrument editing
558 within the sampler's process (by using instrument editor plugins),
559 you'll notice the new "Registered instrument editors:" message on
560 startup, added a new LSCP command:
561 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
562 to spawn a matching instrument editor for the instrument on the
563 given sampler channel, the plugin path can be overridden at compile
564 time with ./configure --enable-plugin-dir=/some/dir
565 - added experimental code for synchronizing instrument editors hosted
566 in the sampler's process to safely edit instruments while playing
567 without a crash (hopefully) by either suspending single regions
568 wherever possible or if unavoidable whole engine(s)
569 - fixed several issues in fundamental "Thread" class: set scheduling
570 policy and priority on thread level, set a minimum stack size for
571 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
572 threads simply inherited properties of starting thread instead of
573 setting their own policy and priority
574 - minor fix in our automatic stack trace mechanism on crashes, the
575 main process did not wait for the stack trace process to finish
576 its output
577 - fixed some minor memory leaks
578 - reenabled assembly features support, at the moment only for
579 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
580 - minor assembly fix in x86 features detection (don't use the PIC
581 register, to avoid relocations in the text segment at runtime)
582 - POSIX callback functions of Thread.h are hidden
583
584 * MIDI driver:
585 - dispatch bank select (MSB and LSB) messages
586
587 * audio driver:
588 - the ALSA audio output driver parameters now reflect the correct
589 parameter value ranges for the respective selected sound card
590 (patch by Till Wimmer, a bit fixed and extended)
591
592 * Gigasampler format engine:
593 - if a filter is used and EG2 finishes before EG1, let the voice
594 die when EG2 has finished (this fixes a problem with clicks and
595 voice starvation for some gigs)
596 - playback is no longer disabled during instrument loading
597 - all notes playing on a channel that changes its instrument keep
598 playing with the old instrument until they get a note off
599 command
600 - EG fix: a release value of zero could cause noises or crash
601 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
602 - EG fine tuning: when attack is zero the EG starts at a level
603 above max sustain level, which means that there is a decay phase
604 even if sustain is 100%
605 - more EG fixes: the level could sometimes go below zero and cause
606 noises or crashes
607 - minor fix of EGDecay (patch by Toshi Nagata)
608 - fixed compiler error when --enable-override-filter-type was
609 supplied to the configure script (fixes #46)
610 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
611 instead of a fix value
612 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
613 127 (solo mode) only kill voices if the respective mode really
614 changed
615
616 * LSCP server:
617 - fixed compile time error for old Bison versions
618 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
619 - parser now supports extended ASCII character set
620 (up to ASCII code 255, i.e. includes now umlauts and accents)
621 - filename arguments in LSCP commands now allow to use escape
622 sequences, that is directly literal as one of: \', \", \\, \n, \r,
623 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
624 code value like \xf2) (fixes bug #24)
625 - the following LSCP commands now also support escape sequences for at
626 least one of their text-based parameters (i.e. name, description):
627 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
628 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
629 "SET DB_INSTRUMENT_DIRECTORY NAME",
630 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
631 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
632 "FIND DB_INSTRUMENT_DIRECTORIES"
633 - returns verbose syntax errors (line and column where syntax error
634 occured, the unexpected character and the actually expected, possible
635 character(s), the latter only if less than 5 possibilities)
636 - made sure that LSCP syntax is not affected by gigedit locale
637 settings
638 - bugfix regarding strings parameter lists: all comma separated lists
639 of strings were treated as being one string containing commas
640 (fixes #57)
641
642 * Bug fixes:
643 - fixed crash occurring on certain LSCP scripts (Bug 39)
644 - another thread safety fix for lscp "load engine" and "set
645 channel audio output device"
646 - fixed a crash which occurs when reassigning the same engine
647 on a sampler channel with connected MIDI device
648 - fixed a crash which occurs when changing the number of ports of a MIDI
649 device connected to a sampler channel to number less then or equal
650 to the index of the port to which the sampler channel is connected.
651 - The previous bindings were not been disconnected when altering
652 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
653 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
654 - The active stream/voice count statistic was incorrect.
655 - notification events were not been sent for some sampler
656 channel changes
657 - added default min and max values to restrict the number of allowed
658 audio output channels and MIDI input ports
659 - the connection to the PCM interface is now closed when destroying
660 an audio output device
661 - files with slash in their path or filename could not be loaded
662
663 * test cases:
664 - updated and fixed (haven't been touched in a while)
665
666 Version 0.4.0 (24 November 2006)
667
668 * packaging changes:
669 - changed deprecated copyright attribute to license; added ldconfig
670 to post-(un)install steps; added devel package for liblinuxsampler;
671 to linuxsampler.spec (RPM)
672 - install necessary development header files for allowing 3rd party
673 applications to link against liblinuxsampler
674 - liblinuxsampler's API documentation can be generated with 'make docs'
675 (Doxygen required)
676 - added benchmark to automatically detect the best triangle LFO
677 implementation (currently either an integer math solution or a
678 di-harmonic approximation), automatic detection can be overriden
679 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
680 configure script argument though (mandatory for cross-compilation)
681 - do not automatically pick optimized gcc flags if the user already
682 provided some on his own (as CXXFLAGS)
683 - added compile time option to disable processing of All-Notes-Off MIDI
684 messages
685 - added compile time options to allow disabling the various audio and
686 MIDI drivers
687 - fixed automatic GCC CPU switch detection on PPC
688 (patch by Ebrahim Mayat)
689
690 * Gigasampler format engine:
691 - extensive synthesis optimization
692 (reimplementation of EGs and LFO(s), removed synthesis parameter
693 prerendering and the synthesis parameter matrix in general, splitting
694 each audio fragment into subfragments now where each subfragment uses
695 constant pitch and filter coefficients. The volume coefficient is
696 linearly interpolated inside a subfragment, unless
697 --disable-interpolate-volume is set.)
698 - fine tuning of the EG modulation parameters
699 - improved filter cutoff calculation by adding support for the
700 following gig parameters: Cutoff freq (used when no cutoff
701 controller is defined), Control invert, Minimum cutoff, Velocity
702 curve and Velocity range. The keyboard tracking now scales
703 cutoff frequency instead of resonance.
704 - added support for gig parameter Resonance.
705 - fixed bug in sysex handling (patch by Juan Linietsky)
706 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
707 which can be overridden with --enable-global-attenuation
708 - EG fixes: made the length of "attack hold" stage more
709 accurate. Release stage can now start before attack stage
710 ends. Cancel release didn't work when sustain was zero. Attack
711 time now has a minimal value to prevent clicks.
712 - fixed pitch changes larger than one octave
713 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
714 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
715 all modes can be altered via standard GM messages, that is CC5 for
716 altering portamento time, CC65 for enabling / disabling portamento
717 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
718 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
719 parameter) and crossfade
720 - added support for the "attenuation controller threshold" gig
721 parameter
722 - added smoothing of volume changes caused by control change
723 messages
724 - sample loop parameters are now taken from the DimensionRegion
725 instead of the wave chunk
726 - fixed keyswitching for v3 gigs with a number of keyswitch splits
727 not equal to a power of two
728 - reimplementation of the filter algorithm. The new filter is more
729 accurate and supports all gig filter types, including bandreject
730 and lowpass turbo.
731 - real support for 24 bit samples - samples are not truncated to
732 16 bits anymore
733 - support for aftertouch (channel pressure, not polyphonic
734 aftertouch)
735 - LFO1 behaviour fixed (dampening from max volume instead of
736 amplifying from 0)
737
738 * LSCP server:
739 - fixed application exit on broken pipe error (fixes bug #20)
740 - fixed the notification messages delay due to lack of
741 network activity (fixes bug #26)
742 - fixed parser bug which occured on space(s) within device parameters
743 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
744
745 * audio driver:
746 - added aRts audio output driver (by no means RT safe)
747
748 * MIDI driver:
749 - fixed legacy sysex code which caused dispatching of MIDI SysEx
750 messages several times instead of once
751 - API extension for MIDI drivers which already supply exact time stamps
752 for events (i.e. for offline rendering based MIDI drivers)
753 - added checks for bad MIDI data
754
755 * linuxsampler application:
756 - show available sampler engine types on startup
757
758 * general changes:
759 - support for muting sampler channels and solo mode of the same, two new
760 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
761 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
762 introduced for this, the behavior is the same like on a mixer console
763 (patch by Grigor Iliev, a bit adjusted). Also added configure option
764 --enable-process-muted-channels which can be used to enable the
765 processing of muted channels.
766 - support for sostenuto pedal
767 - support for monitoring the total number of active voices
768 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
769 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
770 - fixed some memory management errors
771 - fixed some concurrency problems that could lead to crashes when
772 LSCP commands were executed
773 - fixed crash when instrument loading failed previously on the same
774 sampler channel (fixes bug #36)
775
776 Version 0.3.3 (15 July 2005)
777
778 * packaging changes:
779 - fixed compilation with gcc 4.0
780
781 * Gigasampler format engine:
782 - LFO preprocessing was performed even though the respective LFO was
783 disabled by the instrument patch (minor efficiency fix)
784 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
785 for volume ramp downs in the same fragment (needed for current voice
786 stealing implementation) then simply inform the user with a warning
787 about possible click sounds and reduce the volume ramp down
788 appropriately instead of cancelling the audio device connection
789
790 Version 0.3.2 (24 June 2005)
791
792 * packaging changes:
793 - updated autotools build files to compile on OS X
794 (conditional compilation of CoreMIDI and MidiShare drivers)
795 - hand-crafted assembly optimization code can be disabled with
796 './configure --disable-asm' (definitely not recommended)
797 - fixed 'make dist' rule to include all necessary files
798 - require automake (>= 1.5) for 'make -f Makefile.cvs'
799 (due to 'dist-bzip2' automake option)
800
801 * Gigasampler format engine:
802 - support for the gig parameters for "release velocity response" curves
803 - fine tuning of the EGADSR envelope
804 - volume of release triggered samples now depends on note-on velocity,
805 note length and gig parameter "release trigger decay" instead of
806 note-off velocity.
807 - revised voice stealing
808 (fixes crash and endless loop caused by voice stealing)
809 - don't reset scale tuning on instrument or audio output device change
810 - handle key group conflicts right at the beginning of each fragment
811 instead of when the respective voice is actually launched
812 (fixes undefined behavior if stolen voices belonged to a key group -
813 this case was followed by a "killed voice survived" error message)
814 - fixed minor issue with null/silence samples
815 (those stole voices even though they don't need a voice at all which
816 resulted in "voice stealing didn't work out" messages)
817 - don't reset volume, pan, pitch and MIDI controller values on
818 instrument or audio output device change
819
820 * LSCP server:
821 - fixed some crashes (patch by Grigor Iliev, fixes #19)
822 - fixed LSCP event "CHANNEL_INFO" notification
823 (e.g. did not notify on volume changes or MIDI program change events)
824
825 * linuxsampler application:
826 - added command line parameters --lscp-addr and --lscp-port to override
827 default IP address and port of LSCP server
828
829 Version 0.3.1 (24 May 2005)
830
831 * initial release
