* Added support for MIDI note on velocity filter
* Bumped version to 1.0.0.svn20

1 Version CVS HEAD (?)
3 * packaging changes:
4 - fixed building with newer MinGW-w64
5 - Mac OS X: support the new dir for Core Audio SDK
6 - Mac OS X: fixed building outside source directory
7 - made sure all source files for hostplugins are included when
8 doing "make dist"
9 - removed empty directories left from the cvs to svn migration
10 - fixed compilation with gcc 4.6.1
11 - another "make dist" fix, for the LV2 plugin
12 - made --enable-pthread-testcancel default on Mac OS X
13 - minor Makefile fix for building lscpparser when build and source
14 directories are separate
15 - Mac OS X: made it possible to specify plugin installation dir to
16 configure
17 - Mac OS X: Makefile fix for the install-strip target
18 - fixed compilation with gcc 4.7
19 - fixed configure script error with old autoconf versions
20 - lsatomic.h: use gcc provided atomic functions if building with
21 gcc 4.7 and C++11
22 - modernized configure script
23 - fixed linkage error when building with
24 LDFLAGS="-Wl,--no-undefined" (#190)
26 * general changes:
27 - Refactoring: moved the independent code from
28 the Gigasampler format engine to base classes
29 - command line option '--profile' is currently disabled, since the
30 respective profiling code is currently broken
31 - Introduced support for optional environment variable
32 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
33 where the sampler shall look for instrument editor plugins
34 (patch by Luis Garrido, slightly modified).
35 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
36 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
37 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
38 note (in this implementation of the sampler its simply hard routed to
39 the 1st effect send of the sampler channel, no matter what the actual
40 effect type is)
41 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
42 note (in this implementation of the sampler its simply hard routed to
43 the 2nd effect send of the sampler channel, no matter what the actual
44 effect type is)
45 - implemented support for internal LADSPA effects
46 - raised limit of program change queue from 100 to 512
47 (as suggested by Alex Stone)
48 - implemented sine LFO, pulse LFO and saw LFO
49 - experimental support for per voice equalization
50 - added command line option --exec-after-init
51 - Introduced new C++ API method:
52 EngineChannel::InstrumentFileName(int index)
53 allowing to retrieve the whole list of files used for the loaded
54 instrument on an engine channel (a.k.a. part). Some GigaStudio
55 instruments for example are splitted over several files like
56 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
57 - Added new C++ API method Sampler::GetGlobalMaxVoices().
58 - Added new C++ API method Sampler::GetGlobalMaxStreams().
59 - Added new C++ API method Sampler::SetGlobalMaxVoices().
60 - Added new C++ API method Sampler::SetGlobalMaxStreams().

241 - AU bugfix: failed to destroy its audio/MIDI devices
242 - Listen to all interfaces on Mac OS X (INADDR_ANY)
243 - VST bugfix: If the host called resume() before and after
244 changing sample rate or block size, the number of channels was
245 incorrectly set to two. This caused silence in Cubase 5.
246 - save engine type (gig, sfz or sf2) in plugin state

265 - DSSI bugfix: it wasn't possible to change engine type. The MIDI
266 port and audio channel routing for DSSI plugins are now visible.
267 - LV2: use urid and atom extensions instead of deprecated uri-map
268 and event
269 - LV2: lv2 package 1.0 is now required to build the LV2 plugin

286 to them a la JACK, via the usual sampler APIs
287 - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
288 the driver will automatically connect to other CoreMIDI clients' ports
289 (e.g. external MIDI devices being attached to the Mac)

341 - bugfix: calling SET VOICES (which Fantasia does on start and
342 refresh) could cause instruments to be unloaded
343 - Mac OS X: fixed name collision of enum in EffectControl and
344 wrong name of destructor in AudioOutputDeviceCoreAudio.cpp

347 it caused hanging threads on Windows
348 - Fixed possible crashes due to corrupted MIDI/audio device list
349 after MIDI/audio device creation failure
350 - When creating MIDI instrument map entries with "PERSISTENT" type, the
351 instruments were uselessly precached with zero samples, however it still
352 took the full preloading time and on 1st program change the respective
353 instrument was completely reloaded again.
354 - fixed handling of rapid bank select and program change messages
355 sent to the same sampler channel (patch from the Open Octave
356 project, slightly adjusted)

373 (labelled "Disk stream not available in time")
375 Version 1.0.0 (31 July 2009)
377 * packaging changes:
378 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

393 - fixed building with sqlite installed in a non-standard directory
394 - when cross-compiling, don't try to create instruments.db
395 - fix for new mingw-w64 version, which has usleep
397 * general changes:
398 - bugfix: on some POSIX systems instrument editor plugins refused to
399 load as we used a non-portable Linux specific struct field
400 (fixes bug #70, patch by Ronald Baljeu)
401 - fixed endless loop which occured when loading an instrument editor
402 plugin DLL on Windows systems failed
403 - fixed memory leaks that occurred when liblinuxsampler was unloaded
404 - optimized the SynchronizedConfig class so it doesn't wait
405 unnecessarily long after an update
406 - added support for notifying instrument editors on note-on / note-off
407 events (e.g. to highlight the pressed keys on the virtual keyboard
408 of gigedit)
409 - added support for triggering notes by instrument editors (see above)
410 - be verbose on DLL load errors (on Linux)
411 - fixed di-harmonic triangle LFO implementation (this LFO implementation
412 is only used by very few systems, most pick the int math
413 implementation, which is usually faster)
414 - fixes for audio drivers with varying buffer sizes
415 - experimental support for running LinuxSampler as a DSSI, LV2 and
416 VST plugin

422 - fixed CPU feature detection on x86_64 (maybe fixes #108)
423 - automatic stacktrace mechanism is now turned off by default and can
424 be switched on by command line option "--stacktrace" (the automatic
425 stacktrace mechanism seems to be broken on most systems at the moment)
426 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
427 a pointer to the launched InstrumentEditor object
428 - added optional 3rd party user data parameter for following
429 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
430 InstrumentEditor::Launch(),
431 InstrumentManager::LaunchInstrumentEditor()
432 - theoretical fix: made SynchronizedConfig follow C++0x memory
433 model more strictly
434 - fixes for using large audio device buffers
435 - Windows: add the installation directory to the DLL search path
436 when loading an editor plugin (solves problems with VST and
437 gigedit on systems with other GTK versions installed)
439 * audio driver:
440 - removed the nonsense audio channel constraint (which was hard coded to
441 max. 100 audio channels) for most audio drivers
442 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
443 opposed to the LSCP specs
444 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
445 reflected the wrong value
446 - fixed a memory management bug in ASIO driver
447 - Makefile fix: JACK_CFLAGS wasn't used
448 - JACK: use jack_client_open instead of the deprecated
449 jack_client_new
450 - added (experimental) CoreAudio driver
451 - applied old fixes to the ASIO driver that were included in the
452 previous binary release but accidentally never committed to CVS
453 (fixes #117)
454 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
455 win64)
456 - VST: added support for sample rate and buffer size changes
457 - VST: close editor (Fantasia) when the VST is removed
458 - VST: avoid opening Fantasia more than once for each VST instance
459 - VST: export main function as "main" on Linux too (fix for
460 energyXT)
461 - VST: changed number of output channels from one stereo to 16
462 stereo
463 - added channel routing, fxsends and midi maps to the settings
464 stored in the plugin state
465 - performance optimization of AudioChannel::MixTo() and
466 AudioChannel::CopyTo() methods using GCC vector exensions
467 (if available)
468 - ASIO fixes: avoid initializing the device twice, avoid throwing
469 exception when getting parameters from a disconnected device
471 * MIDI driver:
472 - added JACK MIDI driver
473 - dispatch bank select as ordinary CC as well, the user might seriously
474 want to (mis)use it for some purpose ("fixed" in all current MIDI
475 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
476 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
477 CoreMidi or AU
478 - fixed mingw-w64 compilation error in MME driver
479 - made program change handling in MIDI thread real-time safe by
480 moving the logic to a non-RT thread
481 - fixed minor memory leak in ALSA driver
483 * instruments database:
484 - avoid time consuming samples scanning when adding instruments
485 to the instruments database
486 - added support for handling lost files in the instruments database
487 - Implemented option for adding instruments in separate directories
488 in the instruments database
489 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
490 - work-around for missing fnmatch function on Windows to make
491 instrument database compilable
492 - added instrument database support on Windows
493 works with both standalone mode and VST plugin.
494 the instruments DB file is located in
495 %USERPROFILE%\.linuxsampler\instruments.db which allows different
496 databases for each windows user
497 if no DB is present it automatically creates the .linuxsampler subdir
498 and then creates an empty DB
499 - fixed recursive import, which was broken on Windows
501 * Gigasampler format engine:
502 - fixed a memory leak that could happen when a channel was deleted
503 while notes were playing
504 - made it possible to load an instrument even if the audio thread
505 isn't running
506 - added partial support for the "Controller Triggered" MIDI rule,
507 enough for piano gigs with pedal noise samples
508 - minor fix: only mark FX sends as being modified if really the
509 respective FX send MIDI controller was used
510 - added support for GM global device volume SysEx message
511 (can be selected at compile time to either apply globally to the
512 whole sampler [default] or only to the sampler channels that are
513 connected to the respective MIDI input port the SysEx message arrived
514 on)
515 - bugfix: notes triggered at position 0 in the audio buffer were
516 sometimes wrongly killed in the same buffer, causing no sound to
517 be played
518 - added support for chromatic / drumkit mode Roland GS Sysex message
519 which is usally used to switch a part between chromatic sounds and
520 drumkit sounds (as opposed to their common default setting of MIDI
521 part 10 being a drumkit part and all other ones chromatic parts), in
522 LS however one can switch between the first 16 MIDI instrument maps
523 defined for the sampler
524 - made it possible to create multiple sample channels even if the
525 audio thread isn't running
526 - fixed crash when removing channel with active voices (#116)
527 - bugfix: on sample reference changes (instrument editor), only
528 un-cache the respective sample if it's really not used by any
529 sampler engine anymore
530 - re-cache samples in case they were changed by an instrument editor,
531 e.g. when a sample was added while playing (#82)
532 - fixed hanging notes which occured when note-off event had the exact
533 same time stamp as the voice's note-on event and occured both in the
534 same audio fragment cycle (fixes bug #112)
535 - added support for the "fine tune" and "pitch bend range"
536 instrument-level gig parameters
537 - fixed minor artifacts in pitch bend handling
538 - added support for GS Reset SysEx message
539 - allow gig files to use unlimited downward pitch shifting
540 - added a limit check for upward pitch shifting
541 - bugfix: sometimes, when playing a note twice fast, the second
542 note was silent
543 - fixed crash happening when a pitch bend event arrived at the
544 same time a new instrument was loading
546 * LSCP server:
547 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
548 react on MIDI data arriving on certain sampler channels (so far only
549 Note-On and Note-Off events are sent via this LSCP event)
550 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
551 react on MIDI data arriving on certain MIDI input devices (so far only
552 Note-On and Note-Off events are sent via this LSCP event)
553 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
555 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
556 frontends to send MIDI messages to specific sampler channel
557 - added two additional fields to GET FILE INSTRUMENT INFO command -
559 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
560 was incorrect
561 - Optimized the retrieval of the MIDI instrument mappings
562 - added new LSCP command "SET VOICES" to globally alter the maximum
563 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
564 be triggered respectively
565 - added new LSCP command "SET STREAMS" to globally alter the maximum
566 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
567 which will be triggered respectively
568 - bugfix: retry if "select" returns EINTR (this fixes a crash when
569 a gigedit file dialog is opened)
570 - close all connections when LSCPServer is deleted
571 - hard close of all sockets on exit
572 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
573 driver
575 * Bug fixes:
576 - fixed a crash which occurs when removing a sampler channel waiting
577 to start instrument loading after another channel
578 - fixed a crash which occurs when removing a sampler channel with
579 instrument loading in progress (bug #113)
580 - fixed termination caused by uncaught exception when adding MIDI
581 instrument with PERSISTENT load mode
582 - fixed possible iterator invalidations when resetting the sampler
583 - fixed memory leaks when issuing the following LSCP commands:
588 - fixed possible compilation error when sqlite is not present
589 - fixed orphaned pointers when setting maximum voices limit (bug #118)
590 - fixed crash when changing the audio output device of a sampler
591 channel with loaded instrument and start playing notes
592 - fixed endless loop in Engine::SuspendAll() (bug #120)
593 - fixed a low-level atomic load function that was broken on 64-bit
594 PowerPC, which probably could cause crashes on that platform
595 - fixed a memory management error which could cause a crash when a
596 plugin was unloaded
597 - bugfix: two private structs had the same name, which could cause
598 problems if the linker chose the wrong constructor
599 - fixed low-level ConditionServer usage bug that caused lockups on
600 Windows
603 Version 0.5.1 (6 December 2007)
605 * packaging changes:
606 - added autoconf checks for pthread library
607 - added autoconf check for pthread bug found on certain NPTL-enabled
608 glibc versions (see Gentoo bug report #194076)
609 - added autoconf checks for MS Windows
611 * general changes:
612 - bugfix: the thread used by an editor plugin didn't die when the
613 editor closed
614 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
615 out all the space. operator--() did not apply size_mask after
616 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
617 order to avoid problems with the _NonVolatileReader functions.
618 - bugfix: Stream.h: added a missing divide by BytesPerSample in
619 GetWriteSpace(). Since this function is currently only used in
620 the stream's qsort() compare function, it didn't trigger any
621 bugs.
622 - Resampler.h, Synthesizer.h: cubic interpolation now works in
623 24bit mode too. Faster method to read 24bit words on little
624 endian machines (x86): replaced 3 byte reads + shifts with a 1
625 unaligned 32bit read and shift
626 - experimental support for MS Windows (MIDI input via MME, AUDIO
627 output via ASIO)
628 - made handling of SIGINT signal (Ctrl-C) a bit more robust
629 - support for monitoring the total number of active disk streams
630 (new LSCP commands: GET TOTAL_STREAM_COUNT,
633 * AUDIO driver:
634 - added Windows ASIO low latency audio driver
636 * MIDI driver:
637 - added MME Windows MIDI driver
639 * LSCP server:
640 - added support for Windows style path / filenames, however with
641 forward slash path separators instead of backslash
642 (i.e. "C:/foo/bar.gig")
643 - allow naughty liblscp to send non-string device parameters within
644 apostrophes as well
645 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
646 "LIST FILE INSTRUMENTS <file>" and
647 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
648 about an arbitrary instrument file on the system where the sampler is
649 running on
651 Version 0.5.0 (15 October 2007)
653 * packaging changes:
654 - config.h is not going to be installed along with liblinuxsampler's
655 API header files anymore
656 - only the API relevant header (and source) files will be exported to
657 the Doxygen API documentation (explicitly listed in Doxyfile.in)
658 - added completely new XCode project files for Mac OSX which is now
659 capable to execute our autoconf environment, thus no need anymore
660 to maintain the compile time configuration file (osx/version.h) for
661 OSX manually (patch by Toshi Nagata)
662 - fixed buggy boolean --enable-foo / --disable-foo configure script
663 parameters
664 - global.h now only covers global definitions that are needed for the
665 C++ API header files, all implementation internal global definitions
666 are now in global_private.h
667 - atomic.h is not exposed to the C++ API anymore
668 - no need to include config.h anymore for using LS's API header files
669 - fixed warnings in API doc generation
671 * general changes:
672 - replaced the old, confusing MIDI program change mechanism by a
673 flexible MIDI instrument mapper which allows to map arbitrary
674 (MIDI bank, MIDI program) pairs with arbitrary
675 (engine type, instrument file, file index) triplets which will be
676 loaded on the respective channel when such MIDI program change
677 messages arrive, beside that, each entry allows to define a life-time
678 strategy for the instrument, so the user can define whether the
679 instrument should i.e. be permanently loaded (to be able to switch
680 quickly among sounds) or i.e. loaded just on demand when the
681 respective program change arrives (to safe RAM space), as well as a
682 global volume factor for each entry, so the user can adjust the volume
683 dynamic of his mapped instrument collection without having to modify
684 the instrument files, also one can manage arbitrary amount of such
685 MIDI instrument maps and assign each sampler channel individually
686 a certain map, so that i.e. separation of normal instruments and
687 drumkits is possible
688 - new notification events for tracking changes to audio/MIDI devices,
689 MIDI instrument maps, MIDI instruments, FX sends, global volume.
690 - sampler was limited to load max. 200 instruments in the background
691 due to a constant size RingBuffer FIFO which is now replaced by a
692 dynamic (unlimited) size std::list FIFO
693 - added FX sends, these allow to route audio signals to arbitrary audio
694 output channels for being processed by external effect processors
695 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
696 controllers
697 - global (sampler wide) volume can now be controlled at runtime
698 - Implemented new, improved notification system
699 - fixed compilation errors regarding OSX
700 (patch by Toshi Nagata)
701 - implemented instruments database
702 - added support for escape sequences to the instruments database
703 - added highly experimental support for on-the-fly instrument editing
704 within the sampler's process (by using instrument editor plugins),
705 you'll notice the new "Registered instrument editors:" message on
706 startup, added a new LSCP command:
707 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
708 to spawn a matching instrument editor for the instrument on the
709 given sampler channel, the plugin path can be overridden at compile
710 time with ./configure --enable-plugin-dir=/some/dir
711 - added experimental code for synchronizing instrument editors hosted
712 in the sampler's process to safely edit instruments while playing
713 without a crash (hopefully) by either suspending single regions
714 wherever possible or if unavoidable whole engine(s)
715 - fixed several issues in fundamental "Thread" class: set scheduling
716 policy and priority on thread level, set a minimum stack size for
717 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
718 threads simply inherited properties of starting thread instead of
719 setting their own policy and priority
720 - minor fix in our automatic stack trace mechanism on crashes, the
721 main process did not wait for the stack trace process to finish
722 its output
723 - fixed some minor memory leaks
724 - reenabled assembly features support, at the moment only for
725 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
726 - minor assembly fix in x86 features detection (don't use the PIC
727 register, to avoid relocations in the text segment at runtime)
728 - POSIX callback functions of Thread.h are hidden
730 * MIDI driver:
731 - dispatch bank select (MSB and LSB) messages
733 * audio driver:
734 - the ALSA audio output driver parameters now reflect the correct
735 parameter value ranges for the respective selected sound card
736 (patch by Till Wimmer, a bit fixed and extended)
738 * Gigasampler format engine:
739 - if a filter is used and EG2 finishes before EG1, let the voice
740 die when EG2 has finished (this fixes a problem with clicks and
741 voice starvation for some gigs)
742 - playback is no longer disabled during instrument loading
743 - all notes playing on a channel that changes its instrument keep
744 playing with the old instrument until they get a note off
745 command
746 - EG fix: a release value of zero could cause noises or crash
747 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
748 - EG fine tuning: when attack is zero the EG starts at a level
749 above max sustain level, which means that there is a decay phase
750 even if sustain is 100%
751 - more EG fixes: the level could sometimes go below zero and cause
752 noises or crashes
753 - minor fix of EGDecay (patch by Toshi Nagata)
754 - fixed compiler error when --enable-override-filter-type was
755 supplied to the configure script (fixes #46)
756 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
757 instead of a fix value
758 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
759 127 (solo mode) only kill voices if the respective mode really
760 changed
762 * LSCP server:
763 - fixed compile time error for old Bison versions
764 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
765 - parser now supports extended ASCII character set
766 (up to ASCII code 255, i.e. includes now umlauts and accents)
767 - filename arguments in LSCP commands now allow to use escape
768 sequences, that is directly literal as one of: \', \", \\, \n, \r,
769 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
770 code value like \xf2) (fixes bug #24)
771 - the following LSCP commands now also support escape sequences for at
772 least one of their text-based parameters (i.e. name, description):
779 - returns verbose syntax errors (line and column where syntax error
780 occured, the unexpected character and the actually expected, possible
781 character(s), the latter only if less than 5 possibilities)
782 - made sure that LSCP syntax is not affected by gigedit locale
783 settings
784 - bugfix regarding strings parameter lists: all comma separated lists
785 of strings were treated as being one string containing commas
786 (fixes #57)
788 * Bug fixes:
789 - fixed crash occurring on certain LSCP scripts (Bug 39)
790 - another thread safety fix for lscp "load engine" and "set
791 channel audio output device"
792 - fixed a crash which occurs when reassigning the same engine
793 on a sampler channel with connected MIDI device
794 - fixed a crash which occurs when changing the number of ports of a MIDI
795 device connected to a sampler channel to number less then or equal
796 to the index of the port to which the sampler channel is connected.
797 - The previous bindings were not been disconnected when altering
798 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
799 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
800 - The active stream/voice count statistic was incorrect.
801 - notification events were not been sent for some sampler
802 channel changes
803 - added default min and max values to restrict the number of allowed
804 audio output channels and MIDI input ports
805 - the connection to the PCM interface is now closed when destroying
806 an audio output device
807 - files with slash in their path or filename could not be loaded
809 * test cases:
810 - updated and fixed (haven't been touched in a while)
812 Version 0.4.0 (24 November 2006)
814 * packaging changes:
815 - changed deprecated copyright attribute to license; added ldconfig
816 to post-(un)install steps; added devel package for liblinuxsampler;
817 to linuxsampler.spec (RPM)
818 - install necessary development header files for allowing 3rd party
819 applications to link against liblinuxsampler
820 - liblinuxsampler's API documentation can be generated with 'make docs'
821 (Doxygen required)
822 - added benchmark to automatically detect the best triangle LFO
823 implementation (currently either an integer math solution or a
824 di-harmonic approximation), automatic detection can be overriden
825 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
826 configure script argument though (mandatory for cross-compilation)
827 - do not automatically pick optimized gcc flags if the user already
828 provided some on his own (as CXXFLAGS)
829 - added compile time option to disable processing of All-Notes-Off MIDI
830 messages
831 - added compile time options to allow disabling the various audio and
832 MIDI drivers
833 - fixed automatic GCC CPU switch detection on PPC
834 (patch by Ebrahim Mayat)
836 * Gigasampler format engine:
837 - extensive synthesis optimization
838 (reimplementation of EGs and LFO(s), removed synthesis parameter
839 prerendering and the synthesis parameter matrix in general, splitting
840 each audio fragment into subfragments now where each subfragment uses
841 constant pitch and filter coefficients. The volume coefficient is
842 linearly interpolated inside a subfragment, unless
843 --disable-interpolate-volume is set.)
844 - fine tuning of the EG modulation parameters
845 - improved filter cutoff calculation by adding support for the
846 following gig parameters: Cutoff freq (used when no cutoff
847 controller is defined), Control invert, Minimum cutoff, Velocity
848 curve and Velocity range. The keyboard tracking now scales
849 cutoff frequency instead of resonance.
850 - added support for gig parameter Resonance.
851 - fixed bug in sysex handling (patch by Juan Linietsky)
852 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
853 which can be overridden with --enable-global-attenuation
854 - EG fixes: made the length of "attack hold" stage more
855 accurate. Release stage can now start before attack stage
856 ends. Cancel release didn't work when sustain was zero. Attack
857 time now has a minimal value to prevent clicks.
858 - fixed pitch changes larger than one octave
859 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
860 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
861 all modes can be altered via standard GM messages, that is CC5 for
862 altering portamento time, CC65 for enabling / disabling portamento
863 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
864 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
865 parameter) and crossfade
866 - added support for the "attenuation controller threshold" gig
867 parameter
868 - added smoothing of volume changes caused by control change
869 messages
870 - sample loop parameters are now taken from the DimensionRegion
871 instead of the wave chunk
872 - fixed keyswitching for v3 gigs with a number of keyswitch splits
873 not equal to a power of two
874 - reimplementation of the filter algorithm. The new filter is more
875 accurate and supports all gig filter types, including bandreject
876 and lowpass turbo.
877 - real support for 24 bit samples - samples are not truncated to
878 16 bits anymore
879 - support for aftertouch (channel pressure, not polyphonic
880 aftertouch)
881 - LFO1 behaviour fixed (dampening from max volume instead of
882 amplifying from 0)
884 * LSCP server:
885 - fixed application exit on broken pipe error (fixes bug #20)
886 - fixed the notification messages delay due to lack of
887 network activity (fixes bug #26)
888 - fixed parser bug which occured on space(s) within device parameters
891 * audio driver:
892 - added aRts audio output driver (by no means RT safe)
894 * MIDI driver:
895 - fixed legacy sysex code which caused dispatching of MIDI SysEx
896 messages several times instead of once
897 - API extension for MIDI drivers which already supply exact time stamps
898 for events (i.e. for offline rendering based MIDI drivers)
899 - added checks for bad MIDI data
901 * linuxsampler application:
902 - show available sampler engine types on startup
904 * general changes:
905 - support for muting sampler channels and solo mode of the same, two new
906 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
907 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
908 introduced for this, the behavior is the same like on a mixer console
909 (patch by Grigor Iliev, a bit adjusted). Also added configure option
910 --enable-process-muted-channels which can be used to enable the
911 processing of muted channels.
912 - support for sostenuto pedal
913 - support for monitoring the total number of active voices
916 - fixed some memory management errors
917 - fixed some concurrency problems that could lead to crashes when
918 LSCP commands were executed
919 - fixed crash when instrument loading failed previously on the same
920 sampler channel (fixes bug #36)
922 Version 0.3.3 (15 July 2005)
924 * packaging changes:
925 - fixed compilation with gcc 4.0
927 * Gigasampler format engine:
928 - LFO preprocessing was performed even though the respective LFO was
929 disabled by the instrument patch (minor efficiency fix)
930 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
931 for volume ramp downs in the same fragment (needed for current voice
932 stealing implementation) then simply inform the user with a warning
933 about possible click sounds and reduce the volume ramp down
934 appropriately instead of cancelling the audio device connection
936 Version 0.3.2 (24 June 2005)
938 * packaging changes:
939 - updated autotools build files to compile on OS X
940 (conditional compilation of CoreMIDI and MidiShare drivers)
941 - hand-crafted assembly optimization code can be disabled with
942 './configure --disable-asm' (definitely not recommended)
943 - fixed 'make dist' rule to include all necessary files
944 - require automake (>= 1.5) for 'make -f Makefile.cvs'
945 (due to 'dist-bzip2' automake option)
947 * Gigasampler format engine:
948 - support for the gig parameters for "release velocity response" curves
949 - fine tuning of the EGADSR envelope
950 - volume of release triggered samples now depends on note-on velocity,
951 note length and gig parameter "release trigger decay" instead of
952 note-off velocity.
953 - revised voice stealing
954 (fixes crash and endless loop caused by voice stealing)
955 - don't reset scale tuning on instrument or audio output device change
956 - handle key group conflicts right at the beginning of each fragment
957 instead of when the respective voice is actually launched
