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

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

22 - modernized configure script
23 - fixed linkage error when building with
24 LDFLAGS="-Wl,--no-undefined" (#190)
25
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().
61 - Various "const" and "restrict" optimizations.
62 - all engines: add pan CC value to instrument pan parameter before
63 applying panning, instead of using two separate pan functions in
64 series (#182)
65

71 key
72 - bugfix: pitch LFO controller "internal+aftertouch" was broken
73 - bugfix: filter keyboard tracking was broken
74 - filter performance fix (an unnecessary copy was made of the
75 filter parameters in each sub fragment)
76 - handle special case when pan parameter in gig file has max or
77 min value
78
79 * SFZ format engine:

246 - Listen to all interfaces on Mac OS X (INADDR_ANY)
247 - VST bugfix: If the host called resume() before and after
248 changing sample rate or block size, the number of channels was
249 incorrectly set to two. This caused silence in Cubase 5.
250 - save engine type (gig, sfz or sf2) in plugin state

355 - When creating MIDI instrument map entries with "PERSISTENT" type, the
356 instruments were uselessly precached with zero samples, however it still
357 took the full preloading time and on 1st program change the respective
358 instrument was completely reloaded again.
359 - fixed handling of rapid bank select and program change messages
360 sent to the same sampler channel (patch from the Open Octave
361 project, slightly adjusted)

381
382 * packaging changes:
383 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

405 (fixes bug #70, patch by Ronald Baljeu)
406 - fixed endless loop which occured when loading an instrument editor
407 plugin DLL on Windows systems failed
408 - fixed memory leaks that occurred when liblinuxsampler was unloaded
409 - optimized the SynchronizedConfig class so it doesn't wait
410 unnecessarily long after an update
411 - added support for notifying instrument editors on note-on / note-off
412 events (e.g. to highlight the pressed keys on the virtual keyboard
413 of gigedit)
414 - added support for triggering notes by instrument editors (see above)
415 - be verbose on DLL load errors (on Linux)
416 - fixed di-harmonic triangle LFO implementation (this LFO implementation
417 is only used by very few systems, most pick the int math
418 implementation, which is usually faster)
419 - fixes for audio drivers with varying buffer sizes
420 - experimental support for running LinuxSampler as a DSSI, LV2 and
421 VST plugin
422 - notification events for stream/voice count statistics are now sent
423 only when there are actual changes
424 - added memory ordering constraints to improve stability on
425 multi-core and multi-cpu systems
426 - maximum voices and disk streams can now be altered at runtime
427 - fixed CPU feature detection on x86_64 (maybe fixes #108)
428 - automatic stacktrace mechanism is now turned off by default and can
429 be switched on by command line option "--stacktrace" (the automatic
430 stacktrace mechanism seems to be broken on most systems at the moment)
431 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
432 a pointer to the launched InstrumentEditor object
433 - added optional 3rd party user data parameter for following
434 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
435 InstrumentEditor::Launch(),
436 InstrumentManager::LaunchInstrumentEditor()
437 - theoretical fix: made SynchronizedConfig follow C++0x memory
438 model more strictly
439 - fixes for using large audio device buffers
440 - Windows: add the installation directory to the DLL search path
441 when loading an editor plugin (solves problems with VST and
442 gigedit on systems with other GTK versions installed)
443
444 * audio driver:
445 - removed the nonsense audio channel constraint (which was hard coded to
446 max. 100 audio channels) for most audio drivers
447 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
448 opposed to the LSCP specs
449 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
450 reflected the wrong value
451 - fixed a memory management bug in ASIO driver
452 - Makefile fix: JACK_CFLAGS wasn't used
453 - JACK: use jack_client_open instead of the deprecated
454 jack_client_new
455 - added (experimental) CoreAudio driver
456 - applied old fixes to the ASIO driver that were included in the
457 previous binary release but accidentally never committed to CVS
458 (fixes #117)
459 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
460 win64)
461 - VST: added support for sample rate and buffer size changes
462 - VST: close editor (Fantasia) when the VST is removed
463 - VST: avoid opening Fantasia more than once for each VST instance
464 - VST: export main function as "main" on Linux too (fix for
465 energyXT)
466 - VST: changed number of output channels from one stereo to 16
467 stereo
468 - added channel routing, fxsends and midi maps to the settings
469 stored in the plugin state
470 - performance optimization of AudioChannel::MixTo() and
471 AudioChannel::CopyTo() methods using GCC vector exensions
472 (if available)
473 - ASIO fixes: avoid initializing the device twice, avoid throwing
474 exception when getting parameters from a disconnected device
475
476 * MIDI driver:
477 - added JACK MIDI driver
478 - dispatch bank select as ordinary CC as well, the user might seriously
479 want to (mis)use it for some purpose ("fixed" in all current MIDI
480 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
481 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
482 CoreMidi or AU
483 - fixed mingw-w64 compilation error in MME driver
484 - made program change handling in MIDI thread real-time safe by
485 moving the logic to a non-RT thread
486 - fixed minor memory leak in ALSA driver
487
488 * instruments database:
489 - avoid time consuming samples scanning when adding instruments
490 to the instruments database
491 - added support for handling lost files in the instruments database
492 - Implemented option for adding instruments in separate directories
493 in the instruments database
494 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
495 - work-around for missing fnmatch function on Windows to make
496 instrument database compilable
497 - added instrument database support on Windows
498 works with both standalone mode and VST plugin.
499 the instruments DB file is located in
500 %USERPROFILE%\.linuxsampler\instruments.db which allows different
501 databases for each windows user
502 if no DB is present it automatically creates the .linuxsampler subdir
503 and then creates an empty DB
504 - fixed recursive import, which was broken on Windows
505
506 * Gigasampler format engine:
507 - fixed a memory leak that could happen when a channel was deleted
508 while notes were playing
509 - made it possible to load an instrument even if the audio thread
510 isn't running
511 - added partial support for the "Controller Triggered" MIDI rule,
512 enough for piano gigs with pedal noise samples
513 - minor fix: only mark FX sends as being modified if really the
514 respective FX send MIDI controller was used
515 - added support for GM global device volume SysEx message
516 (can be selected at compile time to either apply globally to the
517 whole sampler [default] or only to the sampler channels that are
518 connected to the respective MIDI input port the SysEx message arrived
519 on)
520 - bugfix: notes triggered at position 0 in the audio buffer were
521 sometimes wrongly killed in the same buffer, causing no sound to
522 be played
523 - added support for chromatic / drumkit mode Roland GS Sysex message
524 which is usally used to switch a part between chromatic sounds and
525 drumkit sounds (as opposed to their common default setting of MIDI
526 part 10 being a drumkit part and all other ones chromatic parts), in
527 LS however one can switch between the first 16 MIDI instrument maps
528 defined for the sampler
529 - made it possible to create multiple sample channels even if the
530 audio thread isn't running
531 - fixed crash when removing channel with active voices (#116)
532 - bugfix: on sample reference changes (instrument editor), only
533 un-cache the respective sample if it's really not used by any
534 sampler engine anymore
535 - re-cache samples in case they were changed by an instrument editor,
536 e.g. when a sample was added while playing (#82)
537 - fixed hanging notes which occured when note-off event had the exact
538 same time stamp as the voice's note-on event and occured both in the
539 same audio fragment cycle (fixes bug #112)
540 - added support for the "fine tune" and "pitch bend range"
541 instrument-level gig parameters
542 - fixed minor artifacts in pitch bend handling
543 - added support for GS Reset SysEx message
544 - allow gig files to use unlimited downward pitch shifting
545 - added a limit check for upward pitch shifting
546 - bugfix: sometimes, when playing a note twice fast, the second
547 note was silent
548 - fixed crash happening when a pitch bend event arrived at the
549 same time a new instrument was loading
550
551 * LSCP server:
552 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
553 react on MIDI data arriving on certain sampler channels (so far only
554 Note-On and Note-Off events are sent via this LSCP event)
555 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
556 react on MIDI data arriving on certain MIDI input devices (so far only
557 Note-On and Note-Off events are sent via this LSCP event)
558 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
559 SET DB_INSTRUMENT FILE_PATH
560 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
561 frontends to send MIDI messages to specific sampler channel
562 - added two additional fields to GET FILE INSTRUMENT INFO command -
563 KEY_BINDINGS and KEYSWITCH_BINDINGS
564 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
565 was incorrect
566 - Optimized the retrieval of the MIDI instrument mappings
567 - added new LSCP command "SET VOICES" to globally alter the maximum
568 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
569 be triggered respectively
570 - added new LSCP command "SET STREAMS" to globally alter the maximum
571 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
572 which will be triggered respectively
573 - bugfix: retry if "select" returns EINTR (this fixes a crash when
574 a gigedit file dialog is opened)
575 - close all connections when LSCPServer is deleted
576 - hard close of all sockets on exit
577 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
578 driver
579
580 * Bug fixes:
581 - fixed a crash which occurs when removing a sampler channel waiting
582 to start instrument loading after another channel
583 - fixed a crash which occurs when removing a sampler channel with
584 instrument loading in progress (bug #113)
585 - fixed termination caused by uncaught exception when adding MIDI
586 instrument with PERSISTENT load mode
587 - fixed possible iterator invalidations when resetting the sampler
588 - fixed memory leaks when issuing the following LSCP commands:
589 GET AUDIO_OUTPUT_DRIVER INFO
590 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
591 GET MIDI_INPUT_DRIVER INFO
592 GET MIDI_INPUT_DRIVER_PARAMETER INFO
593 - fixed possible compilation error when sqlite is not present
594 - fixed orphaned pointers when setting maximum voices limit (bug #118)
595 - fixed crash when changing the audio output device of a sampler
596 channel with loaded instrument and start playing notes
597 - fixed endless loop in Engine::SuspendAll() (bug #120)
598 - fixed a low-level atomic load function that was broken on 64-bit
599 PowerPC, which probably could cause crashes on that platform
600 - fixed a memory management error which could cause a crash when a
601 plugin was unloaded
602 - bugfix: two private structs had the same name, which could cause
603 problems if the linker chose the wrong constructor
604 - fixed low-level ConditionServer usage bug that caused lockups on
605 Windows
606
607
608 Version 0.5.1 (6 December 2007)
609
610 * packaging changes:
611 - added autoconf checks for pthread library
612 - added autoconf check for pthread bug found on certain NPTL-enabled
613 glibc versions (see Gentoo bug report #194076)
614 - added autoconf checks for MS Windows
615
616 * general changes:
617 - bugfix: the thread used by an editor plugin didn't die when the
618 editor closed
619 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
620 out all the space. operator--() did not apply size_mask after
621 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
622 order to avoid problems with the _NonVolatileReader functions.
623 - bugfix: Stream.h: added a missing divide by BytesPerSample in
624 GetWriteSpace(). Since this function is currently only used in
625 the stream's qsort() compare function, it didn't trigger any
626 bugs.
627 - Resampler.h, Synthesizer.h: cubic interpolation now works in
628 24bit mode too. Faster method to read 24bit words on little
629 endian machines (x86): replaced 3 byte reads + shifts with a 1
630 unaligned 32bit read and shift
631 - experimental support for MS Windows (MIDI input via MME, AUDIO
632 output via ASIO)
633 - made handling of SIGINT signal (Ctrl-C) a bit more robust
634 - support for monitoring the total number of active disk streams
635 (new LSCP commands: GET TOTAL_STREAM_COUNT,
636 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
637
638 * AUDIO driver:
639 - added Windows ASIO low latency audio driver
640
641 * MIDI driver:
642 - added MME Windows MIDI driver
643
644 * LSCP server:
645 - added support for Windows style path / filenames, however with
646 forward slash path separators instead of backslash
647 (i.e. "C:/foo/bar.gig")
648 - allow naughty liblscp to send non-string device parameters within
649 apostrophes as well
650 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
651 "LIST FILE INSTRUMENTS <file>" and
652 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
653 about an arbitrary instrument file on the system where the sampler is
654 running on
655
656 Version 0.5.0 (15 October 2007)
657
658 * packaging changes:
659 - config.h is not going to be installed along with liblinuxsampler's
660 API header files anymore
661 - only the API relevant header (and source) files will be exported to
662 the Doxygen API documentation (explicitly listed in Doxyfile.in)
663 - added completely new XCode project files for Mac OSX which is now
664 capable to execute our autoconf environment, thus no need anymore
665 to maintain the compile time configuration file (osx/version.h) for
666 OSX manually (patch by Toshi Nagata)
667 - fixed buggy boolean --enable-foo / --disable-foo configure script
668 parameters
669 - global.h now only covers global definitions that are needed for the
670 C++ API header files, all implementation internal global definitions
671 are now in global_private.h
672 - atomic.h is not exposed to the C++ API anymore
673 - no need to include config.h anymore for using LS's API header files
674 - fixed warnings in API doc generation
675
676 * general changes:
677 - replaced the old, confusing MIDI program change mechanism by a
678 flexible MIDI instrument mapper which allows to map arbitrary
679 (MIDI bank, MIDI program) pairs with arbitrary
680 (engine type, instrument file, file index) triplets which will be
681 loaded on the respective channel when such MIDI program change
682 messages arrive, beside that, each entry allows to define a life-time
683 strategy for the instrument, so the user can define whether the
684 instrument should i.e. be permanently loaded (to be able to switch
685 quickly among sounds) or i.e. loaded just on demand when the
686 respective program change arrives (to safe RAM space), as well as a
687 global volume factor for each entry, so the user can adjust the volume
688 dynamic of his mapped instrument collection without having to modify
689 the instrument files, also one can manage arbitrary amount of such
690 MIDI instrument maps and assign each sampler channel individually
691 a certain map, so that i.e. separation of normal instruments and
692 drumkits is possible
693 - new notification events for tracking changes to audio/MIDI devices,
694 MIDI instrument maps, MIDI instruments, FX sends, global volume.
695 - sampler was limited to load max. 200 instruments in the background
696 due to a constant size RingBuffer FIFO which is now replaced by a
697 dynamic (unlimited) size std::list FIFO
698 - added FX sends, these allow to route audio signals to arbitrary audio
699 output channels for being processed by external effect processors
700 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
701 controllers
702 - global (sampler wide) volume can now be controlled at runtime
703 - Implemented new, improved notification system
704 - fixed compilation errors regarding OSX
705 (patch by Toshi Nagata)
706 - implemented instruments database
707 - added support for escape sequences to the instruments database
708 - added highly experimental support for on-the-fly instrument editing
709 within the sampler's process (by using instrument editor plugins),
710 you'll notice the new "Registered instrument editors:" message on
711 startup, added a new LSCP command:
712 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
713 to spawn a matching instrument editor for the instrument on the
714 given sampler channel, the plugin path can be overridden at compile
715 time with ./configure --enable-plugin-dir=/some/dir
716 - added experimental code for synchronizing instrument editors hosted
717 in the sampler's process to safely edit instruments while playing
718 without a crash (hopefully) by either suspending single regions
719 wherever possible or if unavoidable whole engine(s)
720 - fixed several issues in fundamental "Thread" class: set scheduling
721 policy and priority on thread level, set a minimum stack size for
722 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
723 threads simply inherited properties of starting thread instead of
724 setting their own policy and priority
725 - minor fix in our automatic stack trace mechanism on crashes, the
726 main process did not wait for the stack trace process to finish
727 its output
728 - fixed some minor memory leaks
729 - reenabled assembly features support, at the moment only for
730 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
731 - minor assembly fix in x86 features detection (don't use the PIC
732 register, to avoid relocations in the text segment at runtime)
733 - POSIX callback functions of Thread.h are hidden
734
735 * MIDI driver:
736 - dispatch bank select (MSB and LSB) messages
737
738 * audio driver:
739 - the ALSA audio output driver parameters now reflect the correct
740 parameter value ranges for the respective selected sound card
741 (patch by Till Wimmer, a bit fixed and extended)
742
743 * Gigasampler format engine:
744 - if a filter is used and EG2 finishes before EG1, let the voice
745 die when EG2 has finished (this fixes a problem with clicks and
746 voice starvation for some gigs)
747 - playback is no longer disabled during instrument loading
748 - all notes playing on a channel that changes its instrument keep
749 playing with the old instrument until they get a note off
750 command
751 - EG fix: a release value of zero could cause noises or crash
752 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
753 - EG fine tuning: when attack is zero the EG starts at a level
754 above max sustain level, which means that there is a decay phase
755 even if sustain is 100%
756 - more EG fixes: the level could sometimes go below zero and cause
757 noises or crashes
758 - minor fix of EGDecay (patch by Toshi Nagata)
759 - fixed compiler error when --enable-override-filter-type was
760 supplied to the configure script (fixes #46)
761 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
762 instead of a fix value
763 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
764 127 (solo mode) only kill voices if the respective mode really
765 changed
766
767 * LSCP server:
768 - fixed compile time error for old Bison versions
769 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
770 - parser now supports extended ASCII character set
771 (up to ASCII code 255, i.e. includes now umlauts and accents)
772 - filename arguments in LSCP commands now allow to use escape
773 sequences, that is directly literal as one of: \', \", \\, \n, \r,
774 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
775 code value like \xf2) (fixes bug #24)
776 - the following LSCP commands now also support escape sequences for at
777 least one of their text-based parameters (i.e. name, description):
778 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
779 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
780 "SET DB_INSTRUMENT_DIRECTORY NAME",
781 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
782 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
783 "FIND DB_INSTRUMENT_DIRECTORIES"
784 - returns verbose syntax errors (line and column where syntax error
785 occured, the unexpected character and the actually expected, possible
786 character(s), the latter only if less than 5 possibilities)
787 - made sure that LSCP syntax is not affected by gigedit locale
788 settings
789 - bugfix regarding strings parameter lists: all comma separated lists
790 of strings were treated as being one string containing commas
791 (fixes #57)
792
793 * Bug fixes:
794 - fixed crash occurring on certain LSCP scripts (Bug 39)
795 - another thread safety fix for lscp "load engine" and "set
796 channel audio output device"
797 - fixed a crash which occurs when reassigning the same engine
798 on a sampler channel with connected MIDI device
799 - fixed a crash which occurs when changing the number of ports of a MIDI
800 device connected to a sampler channel to number less then or equal
801 to the index of the port to which the sampler channel is connected.
802 - The previous bindings were not been disconnected when altering
803 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
804 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
805 - The active stream/voice count statistic was incorrect.
806 - notification events were not been sent for some sampler
807 channel changes
808 - added default min and max values to restrict the number of allowed
809 audio output channels and MIDI input ports
810 - the connection to the PCM interface is now closed when destroying
811 an audio output device
812 - files with slash in their path or filename could not be loaded
813
814 * test cases:
815 - updated and fixed (haven't been touched in a while)
816
817 Version 0.4.0 (24 November 2006)
818
819 * packaging changes:
820 - changed deprecated copyright attribute to license; added ldconfig
821 to post-(un)install steps; added devel package for liblinuxsampler;
822 to linuxsampler.spec (RPM)
823 - install necessary development header files for allowing 3rd party
824 applications to link against liblinuxsampler
825 - liblinuxsampler's API documentation can be generated with 'make docs'
826 (Doxygen required)
827 - added benchmark to automatically detect the best triangle LFO
828 implementation (currently either an integer math solution or a
829 di-harmonic approximation), automatic detection can be overriden
830 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
831 configure script argument though (mandatory for cross-compilation)
832 - do not automatically pick optimized gcc flags if the user already
833 provided some on his own (as CXXFLAGS)
834 - added compile time option to disable processing of All-Notes-Off MIDI
835 messages
836 - added compile time options to allow disabling the various audio and
837 MIDI drivers
838 - fixed automatic GCC CPU switch detection on PPC
839 (patch by Ebrahim Mayat)
840
841 * Gigasampler format engine:
842 - extensive synthesis optimization
843 (reimplementation of EGs and LFO(s), removed synthesis parameter
844 prerendering and the synthesis parameter matrix in general, splitting
845 each audio fragment into subfragments now where each subfragment uses
846 constant pitch and filter coefficients. The volume coefficient is
847 linearly interpolated inside a subfragment, unless
848 --disable-interpolate-volume is set.)
849 - fine tuning of the EG modulation parameters
850 - improved filter cutoff calculation by adding support for the
851 following gig parameters: Cutoff freq (used when no cutoff
852 controller is defined), Control invert, Minimum cutoff, Velocity
853 curve and Velocity range. The keyboard tracking now scales
854 cutoff frequency instead of resonance.
855 - added support for gig parameter Resonance.
856 - fixed bug in sysex handling (patch by Juan Linietsky)
857 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
858 which can be overridden with --enable-global-attenuation
859 - EG fixes: made the length of "attack hold" stage more
860 accurate. Release stage can now start before attack stage
861 ends. Cancel release didn't work when sustain was zero. Attack
862 time now has a minimal value to prevent clicks.
863 - fixed pitch changes larger than one octave
864 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
865 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
866 all modes can be altered via standard GM messages, that is CC5 for
867 altering portamento time, CC65 for enabling / disabling portamento
868 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
869 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
870 parameter) and crossfade
871 - added support for the "attenuation controller threshold" gig
872 parameter
873 - added smoothing of volume changes caused by control change
874 messages
875 - sample loop parameters are now taken from the DimensionRegion
876 instead of the wave chunk
877 - fixed keyswitching for v3 gigs with a number of keyswitch splits
878 not equal to a power of two
879 - reimplementation of the filter algorithm. The new filter is more
880 accurate and supports all gig filter types, including bandreject
881 and lowpass turbo.
882 - real support for 24 bit samples - samples are not truncated to
883 16 bits anymore
884 - support for aftertouch (channel pressure, not polyphonic
885 aftertouch)
886 - LFO1 behaviour fixed (dampening from max volume instead of
887 amplifying from 0)
888
889 * LSCP server:
890 - fixed application exit on broken pipe error (fixes bug #20)
891 - fixed the notification messages delay due to lack of
892 network activity (fixes bug #26)
893 - fixed parser bug which occured on space(s) within device parameters
894 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
895
896 * audio driver:
897 - added aRts audio output driver (by no means RT safe)
898
899 * MIDI driver:
900 - fixed legacy sysex code which caused dispatching of MIDI SysEx
901 messages several times instead of once
902 - API extension for MIDI drivers which already supply exact time stamps
903 for events (i.e. for offline rendering based MIDI drivers)
904 - added checks for bad MIDI data
905
906 * linuxsampler application:
907 - show available sampler engine types on startup
908
909 * general changes:
910 - support for muting sampler channels and solo mode of the same, two new
911 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
912 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
913 introduced for this, the behavior is the same like on a mixer console
914 (patch by Grigor Iliev, a bit adjusted). Also added configure option
915 --enable-process-muted-channels which can be used to enable the
916 processing of muted channels.
917 - support for sostenuto pedal
918 - support for monitoring the total number of active voices
919 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
920 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
921 - fixed some memory management errors
922 - fixed some concurrency problems that could lead to crashes when
923 LSCP commands were executed
924 - fixed crash when instrument loading failed previously on the same
925 sampler channel (fixes bug #36)
926
927 Version 0.3.3 (15 July 2005)
928
929 * packaging changes:
930 - fixed compilation with gcc 4.0
931
932 * Gigasampler format engine:
933 - LFO preprocessing was performed even though the respective LFO was
934 disabled by the instrument patch (minor efficiency fix)
935 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
936 for volume ramp downs in the same fragment (needed for current voice
937 stealing implementation) then simply inform the user with a warning
938 about possible click sounds and reduce the volume ramp down
939 appropriately instead of cancelling the audio device connection
940
941 Version 0.3.2 (24 June 2005)
942
943 * packaging changes:
944 - updated autotools build files to compile on OS X
945 (conditional compilation of CoreMIDI and MidiShare drivers)
946 - hand-crafted assembly optimization code can be disabled with
947 './configure --disable-asm' (definitely not recommended)
948 - fixed 'make dist' rule to include all necessary files
949 - require automake (>= 1.5) for 'make -f Makefile.cvs'
950 (due to 'dist-bzip2' automake option)
951
952 * Gigasampler format engine:
953 - support for the gig parameters for "release velocity response" curves
954 - fine tuning of the EGADSR envelope
955 - volume of release triggered samples now depends on note-on velocity,
956 note length and gig parameter "release trigger decay" instead of
957 note-off velocity.
958 - revised voice stealing
959 (fixes crash and endless loop caused by voice stealing)
960 - don't reset scale tuning on instrument or audio output device change
961 - handle key group conflicts right at the beginning of each fragment
962 instead of when the respective voice is actually launched
963 (fixes undefined behavior if stolen voices belonged to a key group -
964 this case was followed by a "killed voice survived" error message)
965 - fixed minor issue with null/silence samples
966 (those stole voices even though they don't need a voice at all which
967 resulted in "voice stealing didn't work out" messages)
968 - don't reset volume, pan, pitch and MIDI controller values on
969 instrument or audio output device change
970
971 * LSCP server:
972 - fixed some crashes (patch by Grigor Iliev, fixes #19)
973 - fixed LSCP event "CHANNEL_INFO" notification
974 (e.g. did not notify on volume changes or MIDI program change events)
975
976 * linuxsampler application:
977 - added command line parameters --lscp-addr and --lscp-port to override
978 default IP address and port of LSCP server
979
980 Version 0.3.1 (24 May 2005)
981
982 * initial release
