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

168 * MIDI driver:
169 - ALSA MIDI driver supports now "NAME" device parameter, for overriding
170 the ALSA sequencer client name
171 - removed limit of maximum amount of MIDI ports per MIDI device, since
172 there is no reason for this limit

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

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

469 * general changes:
470 - bugfix: the thread used by an editor plugin didn't die when the
471 editor closed
472 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
473 out all the space. operator--() did not apply size_mask after
474 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
475 order to avoid problems with the _NonVolatileReader functions.
476 - bugfix: Stream.h: added a missing divide by BytesPerSample in
477 GetWriteSpace(). Since this function is currently only used in
478 the stream's qsort() compare function, it didn't trigger any
479 bugs.
480 - Resampler.h, Synthesizer.h: cubic interpolation now works in
481 24bit mode too. Faster method to read 24bit words on little
482 endian machines (x86): replaced 3 byte reads + shifts with a 1
483 unaligned 32bit read and shift
484 - experimental support for MS Windows (MIDI input via MME, AUDIO
485 output via ASIO)
486 - made handling of SIGINT signal (Ctrl-C) a bit more robust
487 - support for monitoring the total number of active disk streams
488 (new LSCP commands: GET TOTAL_STREAM_COUNT,
489 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
490
491 * AUDIO driver:
492 - added Windows ASIO low latency audio driver
493
494 * MIDI driver:
495 - added MME Windows MIDI driver
496
497 * LSCP server:
498 - added support for Windows style path / filenames, however with
499 forward slash path separators instead of backslash
500 (i.e. "C:/foo/bar.gig")
501 - allow naughty liblscp to send non-string device parameters within
502 apostrophes as well
503 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
504 "LIST FILE INSTRUMENTS <file>" and
505 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
506 about an arbitrary instrument file on the system where the sampler is
507 running on
508
509 Version 0.5.0 (15 October 2007)
510
511 * packaging changes:
512 - config.h is not going to be installed along with liblinuxsampler's
513 API header files anymore
514 - only the API relevant header (and source) files will be exported to
515 the Doxygen API documentation (explicitly listed in Doxyfile.in)
516 - added completely new XCode project files for Mac OSX which is now
517 capable to execute our autoconf environment, thus no need anymore
518 to maintain the compile time configuration file (osx/version.h) for
519 OSX manually (patch by Toshi Nagata)
520 - fixed buggy boolean --enable-foo / --disable-foo configure script
521 parameters
522 - global.h now only covers global definitions that are needed for the
523 C++ API header files, all implementation internal global definitions
524 are now in global_private.h
525 - atomic.h is not exposed to the C++ API anymore
526 - no need to include config.h anymore for using LS's API header files
527 - fixed warnings in API doc generation
528
529 * general changes:
530 - replaced the old, confusing MIDI program change mechanism by a
531 flexible MIDI instrument mapper which allows to map arbitrary
532 (MIDI bank, MIDI program) pairs with arbitrary
533 (engine type, instrument file, file index) triplets which will be
534 loaded on the respective channel when such MIDI program change
535 messages arrive, beside that, each entry allows to define a life-time
536 strategy for the instrument, so the user can define whether the
537 instrument should i.e. be permanently loaded (to be able to switch
538 quickly among sounds) or i.e. loaded just on demand when the
539 respective program change arrives (to safe RAM space), as well as a
540 global volume factor for each entry, so the user can adjust the volume
541 dynamic of his mapped instrument collection without having to modify
542 the instrument files, also one can manage arbitrary amount of such
543 MIDI instrument maps and assign each sampler channel individually
544 a certain map, so that i.e. separation of normal instruments and
545 drumkits is possible
546 - new notification events for tracking changes to audio/MIDI devices,
547 MIDI instrument maps, MIDI instruments, FX sends, global volume.
548 - sampler was limited to load max. 200 instruments in the background
549 due to a constant size RingBuffer FIFO which is now replaced by a
550 dynamic (unlimited) size std::list FIFO
551 - added FX sends, these allow to route audio signals to arbitrary audio
552 output channels for being processed by external effect processors
553 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
554 controllers
555 - global (sampler wide) volume can now be controlled at runtime
556 - Implemented new, improved notification system
557 - fixed compilation errors regarding OSX
558 (patch by Toshi Nagata)
559 - implemented instruments database
560 - added support for escape sequences to the instruments database
561 - added highly experimental support for on-the-fly instrument editing
562 within the sampler's process (by using instrument editor plugins),
563 you'll notice the new "Registered instrument editors:" message on
564 startup, added a new LSCP command:
565 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
566 to spawn a matching instrument editor for the instrument on the
567 given sampler channel, the plugin path can be overridden at compile
568 time with ./configure --enable-plugin-dir=/some/dir
569 - added experimental code for synchronizing instrument editors hosted
570 in the sampler's process to safely edit instruments while playing
571 without a crash (hopefully) by either suspending single regions
572 wherever possible or if unavoidable whole engine(s)
573 - fixed several issues in fundamental "Thread" class: set scheduling
574 policy and priority on thread level, set a minimum stack size for
575 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
576 threads simply inherited properties of starting thread instead of
577 setting their own policy and priority
578 - minor fix in our automatic stack trace mechanism on crashes, the
579 main process did not wait for the stack trace process to finish
580 its output
581 - fixed some minor memory leaks
582 - reenabled assembly features support, at the moment only for
583 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
584 - minor assembly fix in x86 features detection (don't use the PIC
585 register, to avoid relocations in the text segment at runtime)
586 - POSIX callback functions of Thread.h are hidden
587
588 * MIDI driver:
589 - dispatch bank select (MSB and LSB) messages
590
591 * audio driver:
592 - the ALSA audio output driver parameters now reflect the correct
593 parameter value ranges for the respective selected sound card
594 (patch by Till Wimmer, a bit fixed and extended)
595
596 * Gigasampler format engine:
597 - if a filter is used and EG2 finishes before EG1, let the voice
598 die when EG2 has finished (this fixes a problem with clicks and
599 voice starvation for some gigs)
600 - playback is no longer disabled during instrument loading
601 - all notes playing on a channel that changes its instrument keep
602 playing with the old instrument until they get a note off
603 command
604 - EG fix: a release value of zero could cause noises or crash
605 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
606 - EG fine tuning: when attack is zero the EG starts at a level
607 above max sustain level, which means that there is a decay phase
608 even if sustain is 100%
609 - more EG fixes: the level could sometimes go below zero and cause
610 noises or crashes
611 - minor fix of EGDecay (patch by Toshi Nagata)
612 - fixed compiler error when --enable-override-filter-type was
613 supplied to the configure script (fixes #46)
614 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
615 instead of a fix value
616 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
617 127 (solo mode) only kill voices if the respective mode really
618 changed
619
620 * LSCP server:
621 - fixed compile time error for old Bison versions
622 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
623 - parser now supports extended ASCII character set
624 (up to ASCII code 255, i.e. includes now umlauts and accents)
625 - filename arguments in LSCP commands now allow to use escape
626 sequences, that is directly literal as one of: \', \", \\, \n, \r,
627 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
628 code value like \xf2) (fixes bug #24)
629 - the following LSCP commands now also support escape sequences for at
630 least one of their text-based parameters (i.e. name, description):
631 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
632 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
633 "SET DB_INSTRUMENT_DIRECTORY NAME",
634 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
635 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
636 "FIND DB_INSTRUMENT_DIRECTORIES"
637 - returns verbose syntax errors (line and column where syntax error
638 occured, the unexpected character and the actually expected, possible
639 character(s), the latter only if less than 5 possibilities)
640 - made sure that LSCP syntax is not affected by gigedit locale
641 settings
642 - bugfix regarding strings parameter lists: all comma separated lists
643 of strings were treated as being one string containing commas
644 (fixes #57)
645
646 * Bug fixes:
647 - fixed crash occurring on certain LSCP scripts (Bug 39)
648 - another thread safety fix for lscp "load engine" and "set
649 channel audio output device"
650 - fixed a crash which occurs when reassigning the same engine
651 on a sampler channel with connected MIDI device
652 - fixed a crash which occurs when changing the number of ports of a MIDI
653 device connected to a sampler channel to number less then or equal
654 to the index of the port to which the sampler channel is connected.
655 - The previous bindings were not been disconnected when altering
656 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
657 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
658 - The active stream/voice count statistic was incorrect.
659 - notification events were not been sent for some sampler
660 channel changes
661 - added default min and max values to restrict the number of allowed
662 audio output channels and MIDI input ports
663 - the connection to the PCM interface is now closed when destroying
664 an audio output device
665 - files with slash in their path or filename could not be loaded
666
667 * test cases:
668 - updated and fixed (haven't been touched in a while)
669
670 Version 0.4.0 (24 November 2006)
671
672 * packaging changes:
673 - changed deprecated copyright attribute to license; added ldconfig
674 to post-(un)install steps; added devel package for liblinuxsampler;
675 to linuxsampler.spec (RPM)
676 - install necessary development header files for allowing 3rd party
677 applications to link against liblinuxsampler
678 - liblinuxsampler's API documentation can be generated with 'make docs'
679 (Doxygen required)
680 - added benchmark to automatically detect the best triangle LFO
681 implementation (currently either an integer math solution or a
682 di-harmonic approximation), automatic detection can be overriden
683 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
684 configure script argument though (mandatory for cross-compilation)
685 - do not automatically pick optimized gcc flags if the user already
686 provided some on his own (as CXXFLAGS)
687 - added compile time option to disable processing of All-Notes-Off MIDI
688 messages
689 - added compile time options to allow disabling the various audio and
690 MIDI drivers
691 - fixed automatic GCC CPU switch detection on PPC
692 (patch by Ebrahim Mayat)
693
694 * Gigasampler format engine:
695 - extensive synthesis optimization
696 (reimplementation of EGs and LFO(s), removed synthesis parameter
697 prerendering and the synthesis parameter matrix in general, splitting
698 each audio fragment into subfragments now where each subfragment uses
699 constant pitch and filter coefficients. The volume coefficient is
700 linearly interpolated inside a subfragment, unless
701 --disable-interpolate-volume is set.)
702 - fine tuning of the EG modulation parameters
703 - improved filter cutoff calculation by adding support for the
704 following gig parameters: Cutoff freq (used when no cutoff
705 controller is defined), Control invert, Minimum cutoff, Velocity
706 curve and Velocity range. The keyboard tracking now scales
707 cutoff frequency instead of resonance.
708 - added support for gig parameter Resonance.
709 - fixed bug in sysex handling (patch by Juan Linietsky)
710 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
711 which can be overridden with --enable-global-attenuation
712 - EG fixes: made the length of "attack hold" stage more
713 accurate. Release stage can now start before attack stage
714 ends. Cancel release didn't work when sustain was zero. Attack
715 time now has a minimal value to prevent clicks.
716 - fixed pitch changes larger than one octave
717 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
718 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
719 all modes can be altered via standard GM messages, that is CC5 for
720 altering portamento time, CC65 for enabling / disabling portamento
721 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
722 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
723 parameter) and crossfade
724 - added support for the "attenuation controller threshold" gig
725 parameter
726 - added smoothing of volume changes caused by control change
727 messages
728 - sample loop parameters are now taken from the DimensionRegion
729 instead of the wave chunk
730 - fixed keyswitching for v3 gigs with a number of keyswitch splits
731 not equal to a power of two
732 - reimplementation of the filter algorithm. The new filter is more
733 accurate and supports all gig filter types, including bandreject
734 and lowpass turbo.
735 - real support for 24 bit samples - samples are not truncated to
736 16 bits anymore
737 - support for aftertouch (channel pressure, not polyphonic
738 aftertouch)
739 - LFO1 behaviour fixed (dampening from max volume instead of
740 amplifying from 0)
741
742 * LSCP server:
743 - fixed application exit on broken pipe error (fixes bug #20)
744 - fixed the notification messages delay due to lack of
745 network activity (fixes bug #26)
746 - fixed parser bug which occured on space(s) within device parameters
747 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
748
749 * audio driver:
750 - added aRts audio output driver (by no means RT safe)
751
752 * MIDI driver:
753 - fixed legacy sysex code which caused dispatching of MIDI SysEx
754 messages several times instead of once
755 - API extension for MIDI drivers which already supply exact time stamps
756 for events (i.e. for offline rendering based MIDI drivers)
757 - added checks for bad MIDI data
758
759 * linuxsampler application:
760 - show available sampler engine types on startup
761
762 * general changes:
763 - support for muting sampler channels and solo mode of the same, two new
764 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
765 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
766 introduced for this, the behavior is the same like on a mixer console
767 (patch by Grigor Iliev, a bit adjusted). Also added configure option
768 --enable-process-muted-channels which can be used to enable the
769 processing of muted channels.
770 - support for sostenuto pedal
771 - support for monitoring the total number of active voices
772 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
773 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
774 - fixed some memory management errors
775 - fixed some concurrency problems that could lead to crashes when
776 LSCP commands were executed
777 - fixed crash when instrument loading failed previously on the same
778 sampler channel (fixes bug #36)
779
780 Version 0.3.3 (15 July 2005)
781
782 * packaging changes:
783 - fixed compilation with gcc 4.0
784
785 * Gigasampler format engine:
786 - LFO preprocessing was performed even though the respective LFO was
787 disabled by the instrument patch (minor efficiency fix)
788 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
789 for volume ramp downs in the same fragment (needed for current voice
790 stealing implementation) then simply inform the user with a warning
791 about possible click sounds and reduce the volume ramp down
792 appropriately instead of cancelling the audio device connection
793
794 Version 0.3.2 (24 June 2005)
795
796 * packaging changes:
797 - updated autotools build files to compile on OS X
798 (conditional compilation of CoreMIDI and MidiShare drivers)
799 - hand-crafted assembly optimization code can be disabled with
800 './configure --disable-asm' (definitely not recommended)
801 - fixed 'make dist' rule to include all necessary files
802 - require automake (>= 1.5) for 'make -f Makefile.cvs'
803 (due to 'dist-bzip2' automake option)
804
805 * Gigasampler format engine:
806 - support for the gig parameters for "release velocity response" curves
807 - fine tuning of the EGADSR envelope
808 - volume of release triggered samples now depends on note-on velocity,
809 note length and gig parameter "release trigger decay" instead of
810 note-off velocity.
811 - revised voice stealing
812 (fixes crash and endless loop caused by voice stealing)
813 - don't reset scale tuning on instrument or audio output device change
814 - handle key group conflicts right at the beginning of each fragment
815 instead of when the respective voice is actually launched
816 (fixes undefined behavior if stolen voices belonged to a key group -
817 this case was followed by a "killed voice survived" error message)
818 - fixed minor issue with null/silence samples
819 (those stole voices even though they don't need a voice at all which
820 resulted in "voice stealing didn't work out" messages)
821 - don't reset volume, pan, pitch and MIDI controller values on
822 instrument or audio output device change
823
824 * LSCP server:
825 - fixed some crashes (patch by Grigor Iliev, fixes #19)
826 - fixed LSCP event "CHANNEL_INFO" notification
827 (e.g. did not notify on volume changes or MIDI program change events)
828
829 * linuxsampler application:
830 - added command line parameters --lscp-addr and --lscp-port to override
831 default IP address and port of LSCP server
832
833 Version 0.3.1 (24 May 2005)
834
835 * initial release
