* sfz/sf2 engine: fixed crash when using small audio fragment size

1 Version CVS HEAD (?)
2
3 * plugin changes:
4 - LV2 "state" extension support (patch by David Robillard)
5
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
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
27 - Introduced support for optional environment variable
28 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
29 where the sampler shall look for instrument editor plugins
30 (patch by Luis Garrido, slightly modified).
31 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
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
40 effect type is)
41 - implemented support for internal LADSPA effects
42 - raised limit of program change queue from 100 to 512
43 (as suggested by Alex Stone)
44 - implemented sine LFO, pulse LFO and saw LFO
45 - experimental support for per voice equalization
46 - added command line option --exec-after-init
47
48 * Gigasampler format engine:

302 - bugfix: calling SET VOICES (which Fantasia does on start and
303 refresh) could cause instruments to be unloaded
304 - Mac OS X: fixed name collision of enum in EffectControl and
305 wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
306 - Mac OS X: fixed hanging threads
307 - Windows: disabled the previous thread fix on non-Mac systems, as
308 it caused hanging threads on Windows

310 after MIDI/audio device creation failure
311 - When creating MIDI instrument map entries with "PERSISTENT" type, the
312 instruments were uselessly precached with zero samples, however it still
313 took the full preloading time and on 1st program change the respective
314 instrument was completely reloaded again.
315 - fixed handling of rapid bank select and program change messages
316 sent to the same sampler channel (patch from the Open Octave
317 project, slightly adjusted)

329 Version 1.0.0 (31 July 2009)
330
331 * packaging changes:

333 causing e.g. the libgig test to fail when
334 "./configure --disable-jack-driver" was used
335 (patch by Alexis Ballier)
336 - fixed compilation with gcc 4.3
337 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
338 - fixed configure so it detects x86_64 (#107)
339 - fixes for building with newer MinGW versions
340 - fix for building with bison 2.4 (#111)
341 - fixed building with libgig installed in a non-standard directory
342 - minor fix in configure for mmsystem.h detection on MinGW
343 - Windows: look for editor plugins and Fantasia using base
344 directory of liblinuxsampler dll (look in the same directory and one
345 directory above)
346 - configure script fix: removed unconditional use of SSE
347 - fixed building with sqlite installed in a non-standard directory
348 - when cross-compiling, don't try to create instruments.db
349 - fix for new mingw-w64 version, which has usleep
350
351 * general changes:
352 - bugfix: on some POSIX systems instrument editor plugins refused to
353 load as we used a non-portable Linux specific struct field
354 (fixes bug #70, patch by Ronald Baljeu)
355 - fixed endless loop which occured when loading an instrument editor
356 plugin DLL on Windows systems failed
357 - fixed memory leaks that occurred when liblinuxsampler was unloaded
358 - optimized the SynchronizedConfig class so it doesn't wait
359 unnecessarily long after an update

361 events (e.g. to highlight the pressed keys on the virtual keyboard
362 of gigedit)
363 - added support for triggering notes by instrument editors (see above)
364 - be verbose on DLL load errors (on Linux)
365 - fixed di-harmonic triangle LFO implementation (this LFO implementation
366 is only used by very few systems, most pick the int math
367 implementation, which is usually faster)
368 - fixes for audio drivers with varying buffer sizes
369 - experimental support for running LinuxSampler as a DSSI, LV2 and
370 VST plugin
371 - notification events for stream/voice count statistics are now sent
372 only when there are actual changes

375 - maximum voices and disk streams can now be altered at runtime
376 - fixed CPU feature detection on x86_64 (maybe fixes #108)
377 - automatic stacktrace mechanism is now turned off by default and can
378 be switched on by command line option "--stacktrace" (the automatic
379 stacktrace mechanism seems to be broken on most systems at the moment)
380 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
381 a pointer to the launched InstrumentEditor object
382 - added optional 3rd party user data parameter for following
383 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
384 InstrumentEditor::Launch(),
385 InstrumentManager::LaunchInstrumentEditor()
386 - theoretical fix: made SynchronizedConfig follow C++0x memory
387 model more strictly
388 - fixes for using large audio device buffers
389 - Windows: add the installation directory to the DLL search path
390 when loading an editor plugin (solves problems with VST and
391 gigedit on systems with other GTK versions installed)
392
393 * audio driver:
394 - removed the nonsense audio channel constraint (which was hard coded to
395 max. 100 audio channels) for most audio drivers
396 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
397 opposed to the LSCP specs
398 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
399 reflected the wrong value
400 - fixed a memory management bug in ASIO driver
401 - Makefile fix: JACK_CFLAGS wasn't used
402 - JACK: use jack_client_open instead of the deprecated
403 jack_client_new

409 win64)
410 - VST: added support for sample rate and buffer size changes
411 - VST: close editor (Fantasia) when the VST is removed
412 - VST: avoid opening Fantasia more than once for each VST instance
413 - VST: export main function as "main" on Linux too (fix for
414 energyXT)
415 - VST: changed number of output channels from one stereo to 16
416 stereo
417 - added channel routing, fxsends and midi maps to the settings
418 stored in the plugin state
419 - performance optimization of AudioChannel::MixTo() and
420 AudioChannel::CopyTo() methods using GCC vector exensions
421 (if available)
422 - ASIO fixes: avoid initializing the device twice, avoid throwing
423 exception when getting parameters from a disconnected device
424
425 * MIDI driver:
426 - added JACK MIDI driver
427 - dispatch bank select as ordinary CC as well, the user might seriously
428 want to (mis)use it for some purpose ("fixed" in all current MIDI
429 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
430 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
431 CoreMidi or AU
432 - fixed mingw-w64 compilation error in MME driver
433 - made program change handling in MIDI thread real-time safe by
434 moving the logic to a non-RT thread
435 - fixed minor memory leak in ALSA driver
436
437 * instruments database:
438 - avoid time consuming samples scanning when adding instruments
439 to the instruments database
440 - added support for handling lost files in the instruments database
441 - Implemented option for adding instruments in separate directories
442 in the instruments database
443 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
444 - work-around for missing fnmatch function on Windows to make
445 instrument database compilable
446 - added instrument database support on Windows
447 works with both standalone mode and VST plugin.
448 the instruments DB file is located in
449 %USERPROFILE%\.linuxsampler\instruments.db which allows different
450 databases for each windows user
451 if no DB is present it automatically creates the .linuxsampler subdir
452 and then creates an empty DB
453 - fixed recursive import, which was broken on Windows
454
455 * Gigasampler format engine:
456 - fixed a memory leak that could happen when a channel was deleted
457 while notes were playing
458 - made it possible to load an instrument even if the audio thread
459 isn't running
460 - added partial support for the "Controller Triggered" MIDI rule,
461 enough for piano gigs with pedal noise samples
462 - minor fix: only mark FX sends as being modified if really the
463 respective FX send MIDI controller was used
464 - added support for GM global device volume SysEx message
465 (can be selected at compile time to either apply globally to the
466 whole sampler [default] or only to the sampler channels that are
467 connected to the respective MIDI input port the SysEx message arrived
468 on)
469 - bugfix: notes triggered at position 0 in the audio buffer were
470 sometimes wrongly killed in the same buffer, causing no sound to
471 be played
472 - added support for chromatic / drumkit mode Roland GS Sysex message
473 which is usally used to switch a part between chromatic sounds and
474 drumkit sounds (as opposed to their common default setting of MIDI
475 part 10 being a drumkit part and all other ones chromatic parts), in
476 LS however one can switch between the first 16 MIDI instrument maps
477 defined for the sampler
478 - made it possible to create multiple sample channels even if the
479 audio thread isn't running
480 - fixed crash when removing channel with active voices (#116)
481 - bugfix: on sample reference changes (instrument editor), only
482 un-cache the respective sample if it's really not used by any
483 sampler engine anymore
484 - re-cache samples in case they were changed by an instrument editor,
485 e.g. when a sample was added while playing (#82)
486 - fixed hanging notes which occured when note-off event had the exact
487 same time stamp as the voice's note-on event and occured both in the
488 same audio fragment cycle (fixes bug #112)
489 - added support for the "fine tune" and "pitch bend range"
490 instrument-level gig parameters
491 - fixed minor artifacts in pitch bend handling
492 - added support for GS Reset SysEx message
493 - allow gig files to use unlimited downward pitch shifting
494 - added a limit check for upward pitch shifting
495 - bugfix: sometimes, when playing a note twice fast, the second
496 note was silent
497 - fixed crash happening when a pitch bend event arrived at the
498 same time a new instrument was loading
499
500 * LSCP server:
501 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
502 react on MIDI data arriving on certain sampler channels (so far only
503 Note-On and Note-Off events are sent via this LSCP event)
504 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
505 react on MIDI data arriving on certain MIDI input devices (so far only
506 Note-On and Note-Off events are sent via this LSCP event)
507 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
508 SET DB_INSTRUMENT FILE_PATH
509 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
510 frontends to send MIDI messages to specific sampler channel
511 - added two additional fields to GET FILE INSTRUMENT INFO command -
512 KEY_BINDINGS and KEYSWITCH_BINDINGS
513 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
514 was incorrect
515 - Optimized the retrieval of the MIDI instrument mappings
516 - added new LSCP command "SET VOICES" to globally alter the maximum
517 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
518 be triggered respectively
519 - added new LSCP command "SET STREAMS" to globally alter the maximum
520 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
521 which will be triggered respectively
522 - bugfix: retry if "select" returns EINTR (this fixes a crash when
523 a gigedit file dialog is opened)
524 - close all connections when LSCPServer is deleted
525 - hard close of all sockets on exit
526 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
527 driver
528
529 * Bug fixes:
530 - fixed a crash which occurs when removing a sampler channel waiting
531 to start instrument loading after another channel
532 - fixed a crash which occurs when removing a sampler channel with
533 instrument loading in progress (bug #113)
534 - fixed termination caused by uncaught exception when adding MIDI
535 instrument with PERSISTENT load mode
536 - fixed possible iterator invalidations when resetting the sampler
537 - fixed memory leaks when issuing the following LSCP commands:
538 GET AUDIO_OUTPUT_DRIVER INFO
539 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
540 GET MIDI_INPUT_DRIVER INFO
541 GET MIDI_INPUT_DRIVER_PARAMETER INFO
542 - fixed possible compilation error when sqlite is not present
543 - fixed orphaned pointers when setting maximum voices limit (bug #118)
544 - fixed crash when changing the audio output device of a sampler
545 channel with loaded instrument and start playing notes
546 - fixed endless loop in Engine::SuspendAll() (bug #120)
547 - fixed a low-level atomic load function that was broken on 64-bit
548 PowerPC, which probably could cause crashes on that platform
549 - fixed a memory management error which could cause a crash when a
550 plugin was unloaded
551 - bugfix: two private structs had the same name, which could cause
552 problems if the linker chose the wrong constructor
553 - fixed low-level ConditionServer usage bug that caused lockups on
554 Windows
555
556
557 Version 0.5.1 (6 December 2007)
558
559 * packaging changes:
560 - added autoconf checks for pthread library
561 - added autoconf check for pthread bug found on certain NPTL-enabled
562 glibc versions (see Gentoo bug report #194076)
563 - added autoconf checks for MS Windows
564
565 * general changes:
566 - bugfix: the thread used by an editor plugin didn't die when the
567 editor closed
568 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
569 out all the space. operator--() did not apply size_mask after
570 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
571 order to avoid problems with the _NonVolatileReader functions.
572 - bugfix: Stream.h: added a missing divide by BytesPerSample in
573 GetWriteSpace(). Since this function is currently only used in
574 the stream's qsort() compare function, it didn't trigger any
575 bugs.
576 - Resampler.h, Synthesizer.h: cubic interpolation now works in
577 24bit mode too. Faster method to read 24bit words on little
578 endian machines (x86): replaced 3 byte reads + shifts with a 1
579 unaligned 32bit read and shift
580 - experimental support for MS Windows (MIDI input via MME, AUDIO
581 output via ASIO)
582 - made handling of SIGINT signal (Ctrl-C) a bit more robust
583 - support for monitoring the total number of active disk streams
584 (new LSCP commands: GET TOTAL_STREAM_COUNT,
585 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
586
587 * AUDIO driver:
588 - added Windows ASIO low latency audio driver
589
590 * MIDI driver:
591 - added MME Windows MIDI driver
592
593 * LSCP server:
594 - added support for Windows style path / filenames, however with
595 forward slash path separators instead of backslash
596 (i.e. "C:/foo/bar.gig")
597 - allow naughty liblscp to send non-string device parameters within
598 apostrophes as well
599 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
600 "LIST FILE INSTRUMENTS <file>" and
601 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
602 about an arbitrary instrument file on the system where the sampler is
603 running on
604
605 Version 0.5.0 (15 October 2007)
606
607 * packaging changes:
608 - config.h is not going to be installed along with liblinuxsampler's
609 API header files anymore
610 - only the API relevant header (and source) files will be exported to
611 the Doxygen API documentation (explicitly listed in Doxyfile.in)
612 - added completely new XCode project files for Mac OSX which is now
613 capable to execute our autoconf environment, thus no need anymore
614 to maintain the compile time configuration file (osx/version.h) for
615 OSX manually (patch by Toshi Nagata)
616 - fixed buggy boolean --enable-foo / --disable-foo configure script
617 parameters
618 - global.h now only covers global definitions that are needed for the
619 C++ API header files, all implementation internal global definitions
620 are now in global_private.h
621 - atomic.h is not exposed to the C++ API anymore
622 - no need to include config.h anymore for using LS's API header files
623 - fixed warnings in API doc generation
624
625 * general changes:
626 - replaced the old, confusing MIDI program change mechanism by a
627 flexible MIDI instrument mapper which allows to map arbitrary
628 (MIDI bank, MIDI program) pairs with arbitrary
629 (engine type, instrument file, file index) triplets which will be
630 loaded on the respective channel when such MIDI program change
631 messages arrive, beside that, each entry allows to define a life-time
632 strategy for the instrument, so the user can define whether the
633 instrument should i.e. be permanently loaded (to be able to switch
634 quickly among sounds) or i.e. loaded just on demand when the
635 respective program change arrives (to safe RAM space), as well as a
636 global volume factor for each entry, so the user can adjust the volume
637 dynamic of his mapped instrument collection without having to modify
638 the instrument files, also one can manage arbitrary amount of such
639 MIDI instrument maps and assign each sampler channel individually
640 a certain map, so that i.e. separation of normal instruments and
641 drumkits is possible
642 - new notification events for tracking changes to audio/MIDI devices,
643 MIDI instrument maps, MIDI instruments, FX sends, global volume.
644 - sampler was limited to load max. 200 instruments in the background
645 due to a constant size RingBuffer FIFO which is now replaced by a
646 dynamic (unlimited) size std::list FIFO
647 - added FX sends, these allow to route audio signals to arbitrary audio
648 output channels for being processed by external effect processors
649 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
650 controllers
651 - global (sampler wide) volume can now be controlled at runtime
652 - Implemented new, improved notification system
653 - fixed compilation errors regarding OSX
654 (patch by Toshi Nagata)
655 - implemented instruments database
656 - added support for escape sequences to the instruments database
657 - added highly experimental support for on-the-fly instrument editing
658 within the sampler's process (by using instrument editor plugins),
659 you'll notice the new "Registered instrument editors:" message on
660 startup, added a new LSCP command:
661 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
662 to spawn a matching instrument editor for the instrument on the
663 given sampler channel, the plugin path can be overridden at compile
664 time with ./configure --enable-plugin-dir=/some/dir
665 - added experimental code for synchronizing instrument editors hosted
666 in the sampler's process to safely edit instruments while playing
667 without a crash (hopefully) by either suspending single regions
668 wherever possible or if unavoidable whole engine(s)
669 - fixed several issues in fundamental "Thread" class: set scheduling
670 policy and priority on thread level, set a minimum stack size for
671 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
672 threads simply inherited properties of starting thread instead of
673 setting their own policy and priority
674 - minor fix in our automatic stack trace mechanism on crashes, the
675 main process did not wait for the stack trace process to finish
676 its output
677 - fixed some minor memory leaks
678 - reenabled assembly features support, at the moment only for
679 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
680 - minor assembly fix in x86 features detection (don't use the PIC
681 register, to avoid relocations in the text segment at runtime)
682 - POSIX callback functions of Thread.h are hidden
683
684 * MIDI driver:
685 - dispatch bank select (MSB and LSB) messages
686
687 * audio driver:
688 - the ALSA audio output driver parameters now reflect the correct
689 parameter value ranges for the respective selected sound card
690 (patch by Till Wimmer, a bit fixed and extended)
691
692 * Gigasampler format engine:
693 - if a filter is used and EG2 finishes before EG1, let the voice
694 die when EG2 has finished (this fixes a problem with clicks and
695 voice starvation for some gigs)
696 - playback is no longer disabled during instrument loading
697 - all notes playing on a channel that changes its instrument keep
698 playing with the old instrument until they get a note off
699 command
700 - EG fix: a release value of zero could cause noises or crash
701 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
702 - EG fine tuning: when attack is zero the EG starts at a level
703 above max sustain level, which means that there is a decay phase
704 even if sustain is 100%
705 - more EG fixes: the level could sometimes go below zero and cause
706 noises or crashes
707 - minor fix of EGDecay (patch by Toshi Nagata)
708 - fixed compiler error when --enable-override-filter-type was
709 supplied to the configure script (fixes #46)
710 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
711 instead of a fix value
712 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
713 127 (solo mode) only kill voices if the respective mode really
714 changed
715
716 * LSCP server:
717 - fixed compile time error for old Bison versions
718 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
719 - parser now supports extended ASCII character set
720 (up to ASCII code 255, i.e. includes now umlauts and accents)
721 - filename arguments in LSCP commands now allow to use escape
722 sequences, that is directly literal as one of: \', \", \\, \n, \r,
723 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
724 code value like \xf2) (fixes bug #24)
725 - the following LSCP commands now also support escape sequences for at
726 least one of their text-based parameters (i.e. name, description):
727 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
728 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
729 "SET DB_INSTRUMENT_DIRECTORY NAME",
730 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
731 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
732 "FIND DB_INSTRUMENT_DIRECTORIES"
733 - returns verbose syntax errors (line and column where syntax error
734 occured, the unexpected character and the actually expected, possible
735 character(s), the latter only if less than 5 possibilities)
736 - made sure that LSCP syntax is not affected by gigedit locale
737 settings
738 - bugfix regarding strings parameter lists: all comma separated lists
739 of strings were treated as being one string containing commas
740 (fixes #57)
741
742 * Bug fixes:
743 - fixed crash occurring on certain LSCP scripts (Bug 39)
744 - another thread safety fix for lscp "load engine" and "set
745 channel audio output device"
746 - fixed a crash which occurs when reassigning the same engine
747 on a sampler channel with connected MIDI device
748 - fixed a crash which occurs when changing the number of ports of a MIDI
749 device connected to a sampler channel to number less then or equal
750 to the index of the port to which the sampler channel is connected.
751 - The previous bindings were not been disconnected when altering
752 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
753 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
754 - The active stream/voice count statistic was incorrect.
755 - notification events were not been sent for some sampler
756 channel changes
757 - added default min and max values to restrict the number of allowed
758 audio output channels and MIDI input ports
759 - the connection to the PCM interface is now closed when destroying
760 an audio output device
761 - files with slash in their path or filename could not be loaded
762
763 * test cases:
764 - updated and fixed (haven't been touched in a while)
765
766 Version 0.4.0 (24 November 2006)
767
768 * packaging changes:
769 - changed deprecated copyright attribute to license; added ldconfig
770 to post-(un)install steps; added devel package for liblinuxsampler;
771 to linuxsampler.spec (RPM)
772 - install necessary development header files for allowing 3rd party
773 applications to link against liblinuxsampler
774 - liblinuxsampler's API documentation can be generated with 'make docs'
775 (Doxygen required)
776 - added benchmark to automatically detect the best triangle LFO
777 implementation (currently either an integer math solution or a
778 di-harmonic approximation), automatic detection can be overriden
779 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
780 configure script argument though (mandatory for cross-compilation)
781 - do not automatically pick optimized gcc flags if the user already
782 provided some on his own (as CXXFLAGS)
783 - added compile time option to disable processing of All-Notes-Off MIDI
784 messages
785 - added compile time options to allow disabling the various audio and
786 MIDI drivers
787 - fixed automatic GCC CPU switch detection on PPC
788 (patch by Ebrahim Mayat)
789
790 * Gigasampler format engine:
791 - extensive synthesis optimization
792 (reimplementation of EGs and LFO(s), removed synthesis parameter
793 prerendering and the synthesis parameter matrix in general, splitting
794 each audio fragment into subfragments now where each subfragment uses
795 constant pitch and filter coefficients. The volume coefficient is
796 linearly interpolated inside a subfragment, unless
797 --disable-interpolate-volume is set.)
798 - fine tuning of the EG modulation parameters
799 - improved filter cutoff calculation by adding support for the
800 following gig parameters: Cutoff freq (used when no cutoff
801 controller is defined), Control invert, Minimum cutoff, Velocity
802 curve and Velocity range. The keyboard tracking now scales
803 cutoff frequency instead of resonance.
804 - added support for gig parameter Resonance.
805 - fixed bug in sysex handling (patch by Juan Linietsky)
806 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
807 which can be overridden with --enable-global-attenuation
808 - EG fixes: made the length of "attack hold" stage more
809 accurate. Release stage can now start before attack stage
810 ends. Cancel release didn't work when sustain was zero. Attack
811 time now has a minimal value to prevent clicks.
812 - fixed pitch changes larger than one octave
813 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
814 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
815 all modes can be altered via standard GM messages, that is CC5 for
816 altering portamento time, CC65 for enabling / disabling portamento
817 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
818 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
819 parameter) and crossfade
820 - added support for the "attenuation controller threshold" gig
821 parameter
822 - added smoothing of volume changes caused by control change
823 messages
824 - sample loop parameters are now taken from the DimensionRegion
825 instead of the wave chunk
826 - fixed keyswitching for v3 gigs with a number of keyswitch splits
827 not equal to a power of two
828 - reimplementation of the filter algorithm. The new filter is more
829 accurate and supports all gig filter types, including bandreject
830 and lowpass turbo.
831 - real support for 24 bit samples - samples are not truncated to
832 16 bits anymore
833 - support for aftertouch (channel pressure, not polyphonic
834 aftertouch)
835 - LFO1 behaviour fixed (dampening from max volume instead of
836 amplifying from 0)
837
838 * LSCP server:
839 - fixed application exit on broken pipe error (fixes bug #20)
840 - fixed the notification messages delay due to lack of
841 network activity (fixes bug #26)
842 - fixed parser bug which occured on space(s) within device parameters
843 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
844
845 * audio driver:
846 - added aRts audio output driver (by no means RT safe)
847
848 * MIDI driver:
849 - fixed legacy sysex code which caused dispatching of MIDI SysEx
850 messages several times instead of once
851 - API extension for MIDI drivers which already supply exact time stamps
852 for events (i.e. for offline rendering based MIDI drivers)
853 - added checks for bad MIDI data
854
855 * linuxsampler application:
856 - show available sampler engine types on startup
857
858 * general changes:
859 - support for muting sampler channels and solo mode of the same, two new
860 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
861 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
862 introduced for this, the behavior is the same like on a mixer console
863 (patch by Grigor Iliev, a bit adjusted). Also added configure option
864 --enable-process-muted-channels which can be used to enable the
865 processing of muted channels.
866 - support for sostenuto pedal
867 - support for monitoring the total number of active voices
868 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
869 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
870 - fixed some memory management errors
871 - fixed some concurrency problems that could lead to crashes when
872 LSCP commands were executed
873 - fixed crash when instrument loading failed previously on the same
874 sampler channel (fixes bug #36)
875
876 Version 0.3.3 (15 July 2005)
877
878 * packaging changes:
879 - fixed compilation with gcc 4.0
880
881 * Gigasampler format engine:
882 - LFO preprocessing was performed even though the respective LFO was
883 disabled by the instrument patch (minor efficiency fix)
884 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
885 for volume ramp downs in the same fragment (needed for current voice
886 stealing implementation) then simply inform the user with a warning
887 about possible click sounds and reduce the volume ramp down
888 appropriately instead of cancelling the audio device connection
889
890 Version 0.3.2 (24 June 2005)
891
892 * packaging changes:
893 - updated autotools build files to compile on OS X
894 (conditional compilation of CoreMIDI and MidiShare drivers)
895 - hand-crafted assembly optimization code can be disabled with
896 './configure --disable-asm' (definitely not recommended)
897 - fixed 'make dist' rule to include all necessary files
898 - require automake (>= 1.5) for 'make -f Makefile.cvs'
899 (due to 'dist-bzip2' automake option)
900
901 * Gigasampler format engine:
902 - support for the gig parameters for "release velocity response" curves
903 - fine tuning of the EGADSR envelope
904 - volume of release triggered samples now depends on note-on velocity,
905 note length and gig parameter "release trigger decay" instead of
906 note-off velocity.
907 - revised voice stealing
908 (fixes crash and endless loop caused by voice stealing)
909 - don't reset scale tuning on instrument or audio output device change
910 - handle key group conflicts right at the beginning of each fragment
911 instead of when the respective voice is actually launched
912 (fixes undefined behavior if stolen voices belonged to a key group -
913 this case was followed by a "killed voice survived" error message)
914 - fixed minor issue with null/silence samples
915 (those stole voices even though they don't need a voice at all which
916 resulted in "voice stealing didn't work out" messages)
917 - don't reset volume, pan, pitch and MIDI controller values on
918 instrument or audio output device change
919
920 * LSCP server:
921 - fixed some crashes (patch by Grigor Iliev, fixes #19)
922 - fixed LSCP event "CHANNEL_INFO" notification
923 (e.g. did not notify on volume changes or MIDI program change events)
924
