* gig engine: fixed EG1 modulation when attack or release is zero

1 Version CVS HEAD (?)
2
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)
25 - fixed compilation with Clang 3.2
26
27 * general changes:
28 - Refactoring: moved the independent code from
29 the Gigasampler format engine to base classes
30 - command line option '--profile' is currently disabled, since the
31 respective profiling code is currently broken
32 - Introduced support for optional environment variable
33 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
34 where the sampler shall look for instrument editor plugins
35 (patch by Luis Garrido, slightly modified).
36 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
37 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
38 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
39 note (in this implementation of the sampler its simply hard routed to
40 the 1st effect send of the sampler channel, no matter what the actual
41 effect type is)
42 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
43 note (in this implementation of the sampler its simply hard routed to
44 the 2nd effect send of the sampler channel, no matter what the actual
45 effect type is)
46 - implemented support for internal LADSPA effects
47 - raised limit of program change queue from 100 to 512
48 (as suggested by Alex Stone)
49 - implemented sine LFO, pulse LFO and saw LFO
50 - experimental support for per voice equalization
51 - added command line option --exec-after-init
52 - Introduced new C++ API method:
53 EngineChannel::InstrumentFileName(int index)
54 allowing to retrieve the whole list of files used for the loaded
55 instrument on an engine channel (a.k.a. part). Some GigaStudio
56 instruments for example are splitted over several files like
57 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
58 - Added new C++ API method Sampler::GetGlobalMaxVoices().
59 - Added new C++ API method Sampler::GetGlobalMaxStreams().
60 - Added new C++ API method Sampler::SetGlobalMaxVoices().
61 - Added new C++ API method Sampler::SetGlobalMaxStreams().
62 - Various "const" and "restrict" optimizations.
63 - all engines: add pan CC value to instrument pan parameter before
64 applying panning, instead of using two separate pan functions in
65 series (#182)
66
67 * Gigasampler format engine:
68 - implemented the "round robin keyboard" dimension
69 - fixed round robin and random dimensions for cases when number of
70 dimension zones is not a power of two
71 - made round robin use a counter for each region instead of each
72 key
73 - bugfix: pitch LFO controller "internal+aftertouch" was broken
74 - bugfix: filter keyboard tracking was broken
75 - filter performance fix (an unnecessary copy was made of the
76 filter parameters in each sub fragment)
77 - handle special case when pan parameter in gig file has max or
78 min value
79 - Exclusive Groups: don't ever stop voices of the same note,
80 doesn't sound naturally with a drumkit
81 - fixed EG1 modulation when attack or release is zero
82
83 * SFZ format engine:
84 - Initial implementation (not usable yet)

90 - allow non-numerical key values ("C#4" for example)
91 - "key" opcode now sets pitch_keycenter too
92 - fixed error when unloading instrument with same sample used by
93 multiple regions

299 the driver will automatically connect to other CoreMIDI clients' ports
300 (e.g. external MIDI devices being attached to the Mac)
301 - added support for MIDI note on velocity filter
302 - CoreMIDI: fixed memory deallocation error

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

391
392 * packaging changes:
393 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

415 (fixes bug #70, patch by Ronald Baljeu)
416 - fixed endless loop which occured when loading an instrument editor
417 plugin DLL on Windows systems failed
418 - fixed memory leaks that occurred when liblinuxsampler was unloaded
419 - optimized the SynchronizedConfig class so it doesn't wait
420 unnecessarily long after an update
421 - added support for notifying instrument editors on note-on / note-off
422 events (e.g. to highlight the pressed keys on the virtual keyboard
423 of gigedit)
424 - added support for triggering notes by instrument editors (see above)
425 - be verbose on DLL load errors (on Linux)
426 - fixed di-harmonic triangle LFO implementation (this LFO implementation
427 is only used by very few systems, most pick the int math
428 implementation, which is usually faster)
429 - fixes for audio drivers with varying buffer sizes
430 - experimental support for running LinuxSampler as a DSSI, LV2 and
431 VST plugin
432 - notification events for stream/voice count statistics are now sent
433 only when there are actual changes
434 - added memory ordering constraints to improve stability on
435 multi-core and multi-cpu systems
436 - maximum voices and disk streams can now be altered at runtime
437 - fixed CPU feature detection on x86_64 (maybe fixes #108)
438 - automatic stacktrace mechanism is now turned off by default and can
439 be switched on by command line option "--stacktrace" (the automatic
440 stacktrace mechanism seems to be broken on most systems at the moment)
441 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
442 a pointer to the launched InstrumentEditor object
443 - added optional 3rd party user data parameter for following
444 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
445 InstrumentEditor::Launch(),
446 InstrumentManager::LaunchInstrumentEditor()
447 - theoretical fix: made SynchronizedConfig follow C++0x memory
448 model more strictly
449 - fixes for using large audio device buffers
450 - Windows: add the installation directory to the DLL search path
451 when loading an editor plugin (solves problems with VST and
452 gigedit on systems with other GTK versions installed)
453
454 * audio driver:
455 - removed the nonsense audio channel constraint (which was hard coded to
456 max. 100 audio channels) for most audio drivers
457 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
458 opposed to the LSCP specs
459 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
460 reflected the wrong value
461 - fixed a memory management bug in ASIO driver
462 - Makefile fix: JACK_CFLAGS wasn't used
463 - JACK: use jack_client_open instead of the deprecated
464 jack_client_new
465 - added (experimental) CoreAudio driver
466 - applied old fixes to the ASIO driver that were included in the
467 previous binary release but accidentally never committed to CVS
468 (fixes #117)
469 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
470 win64)
471 - VST: added support for sample rate and buffer size changes
472 - VST: close editor (Fantasia) when the VST is removed
473 - VST: avoid opening Fantasia more than once for each VST instance
474 - VST: export main function as "main" on Linux too (fix for
475 energyXT)
476 - VST: changed number of output channels from one stereo to 16
477 stereo
478 - added channel routing, fxsends and midi maps to the settings
479 stored in the plugin state
480 - performance optimization of AudioChannel::MixTo() and
481 AudioChannel::CopyTo() methods using GCC vector exensions
482 (if available)
483 - ASIO fixes: avoid initializing the device twice, avoid throwing
484 exception when getting parameters from a disconnected device
485
486 * MIDI driver:
487 - added JACK MIDI driver
488 - dispatch bank select as ordinary CC as well, the user might seriously
489 want to (mis)use it for some purpose ("fixed" in all current MIDI
490 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
491 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
492 CoreMidi or AU
493 - fixed mingw-w64 compilation error in MME driver
494 - made program change handling in MIDI thread real-time safe by
495 moving the logic to a non-RT thread
496 - fixed minor memory leak in ALSA driver
497
498 * instruments database:
499 - avoid time consuming samples scanning when adding instruments
500 to the instruments database
501 - added support for handling lost files in the instruments database
502 - Implemented option for adding instruments in separate directories
503 in the instruments database
504 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
505 - work-around for missing fnmatch function on Windows to make
506 instrument database compilable
507 - added instrument database support on Windows
508 works with both standalone mode and VST plugin.
509 the instruments DB file is located in
510 %USERPROFILE%\.linuxsampler\instruments.db which allows different
511 databases for each windows user
512 if no DB is present it automatically creates the .linuxsampler subdir
513 and then creates an empty DB
514 - fixed recursive import, which was broken on Windows
515
516 * Gigasampler format engine:
517 - fixed a memory leak that could happen when a channel was deleted
518 while notes were playing
519 - made it possible to load an instrument even if the audio thread
520 isn't running
521 - added partial support for the "Controller Triggered" MIDI rule,
522 enough for piano gigs with pedal noise samples
523 - minor fix: only mark FX sends as being modified if really the
524 respective FX send MIDI controller was used
525 - added support for GM global device volume SysEx message
526 (can be selected at compile time to either apply globally to the
527 whole sampler [default] or only to the sampler channels that are
528 connected to the respective MIDI input port the SysEx message arrived
529 on)
530 - bugfix: notes triggered at position 0 in the audio buffer were
531 sometimes wrongly killed in the same buffer, causing no sound to
532 be played
533 - added support for chromatic / drumkit mode Roland GS Sysex message
534 which is usally used to switch a part between chromatic sounds and
535 drumkit sounds (as opposed to their common default setting of MIDI
536 part 10 being a drumkit part and all other ones chromatic parts), in
537 LS however one can switch between the first 16 MIDI instrument maps
538 defined for the sampler
539 - made it possible to create multiple sample channels even if the
540 audio thread isn't running
541 - fixed crash when removing channel with active voices (#116)
542 - bugfix: on sample reference changes (instrument editor), only
543 un-cache the respective sample if it's really not used by any
544 sampler engine anymore
545 - re-cache samples in case they were changed by an instrument editor,
546 e.g. when a sample was added while playing (#82)
547 - fixed hanging notes which occured when note-off event had the exact
548 same time stamp as the voice's note-on event and occured both in the
549 same audio fragment cycle (fixes bug #112)
550 - added support for the "fine tune" and "pitch bend range"
551 instrument-level gig parameters
552 - fixed minor artifacts in pitch bend handling
553 - added support for GS Reset SysEx message
554 - allow gig files to use unlimited downward pitch shifting
555 - added a limit check for upward pitch shifting
556 - bugfix: sometimes, when playing a note twice fast, the second
557 note was silent
558 - fixed crash happening when a pitch bend event arrived at the
559 same time a new instrument was loading
560
561 * LSCP server:
562 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
563 react on MIDI data arriving on certain sampler channels (so far only
564 Note-On and Note-Off events are sent via this LSCP event)
565 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
566 react on MIDI data arriving on certain MIDI input devices (so far only
567 Note-On and Note-Off events are sent via this LSCP event)
568 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
569 SET DB_INSTRUMENT FILE_PATH
570 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
571 frontends to send MIDI messages to specific sampler channel
572 - added two additional fields to GET FILE INSTRUMENT INFO command -
573 KEY_BINDINGS and KEYSWITCH_BINDINGS
574 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
575 was incorrect
576 - Optimized the retrieval of the MIDI instrument mappings
577 - added new LSCP command "SET VOICES" to globally alter the maximum
578 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
579 be triggered respectively
580 - added new LSCP command "SET STREAMS" to globally alter the maximum
581 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
582 which will be triggered respectively
583 - bugfix: retry if "select" returns EINTR (this fixes a crash when
584 a gigedit file dialog is opened)
585 - close all connections when LSCPServer is deleted
586 - hard close of all sockets on exit
587 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
588 driver
589
590 * Bug fixes:
591 - fixed a crash which occurs when removing a sampler channel waiting
592 to start instrument loading after another channel
593 - fixed a crash which occurs when removing a sampler channel with
594 instrument loading in progress (bug #113)
595 - fixed termination caused by uncaught exception when adding MIDI
596 instrument with PERSISTENT load mode
597 - fixed possible iterator invalidations when resetting the sampler
598 - fixed memory leaks when issuing the following LSCP commands:
599 GET AUDIO_OUTPUT_DRIVER INFO
600 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
601 GET MIDI_INPUT_DRIVER INFO
602 GET MIDI_INPUT_DRIVER_PARAMETER INFO
603 - fixed possible compilation error when sqlite is not present
604 - fixed orphaned pointers when setting maximum voices limit (bug #118)
605 - fixed crash when changing the audio output device of a sampler
606 channel with loaded instrument and start playing notes
607 - fixed endless loop in Engine::SuspendAll() (bug #120)
608 - fixed a low-level atomic load function that was broken on 64-bit
609 PowerPC, which probably could cause crashes on that platform
610 - fixed a memory management error which could cause a crash when a
611 plugin was unloaded
612 - bugfix: two private structs had the same name, which could cause
613 problems if the linker chose the wrong constructor
614 - fixed low-level ConditionServer usage bug that caused lockups on
615 Windows
616
617
618 Version 0.5.1 (6 December 2007)
619
620 * packaging changes:
621 - added autoconf checks for pthread library
622 - added autoconf check for pthread bug found on certain NPTL-enabled
623 glibc versions (see Gentoo bug report #194076)
624 - added autoconf checks for MS Windows
625
626 * general changes:
627 - bugfix: the thread used by an editor plugin didn't die when the
628 editor closed
629 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
630 out all the space. operator--() did not apply size_mask after
631 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
632 order to avoid problems with the _NonVolatileReader functions.
633 - bugfix: Stream.h: added a missing divide by BytesPerSample in
634 GetWriteSpace(). Since this function is currently only used in
635 the stream's qsort() compare function, it didn't trigger any
636 bugs.
637 - Resampler.h, Synthesizer.h: cubic interpolation now works in
638 24bit mode too. Faster method to read 24bit words on little
639 endian machines (x86): replaced 3 byte reads + shifts with a 1
640 unaligned 32bit read and shift
641 - experimental support for MS Windows (MIDI input via MME, AUDIO
642 output via ASIO)
643 - made handling of SIGINT signal (Ctrl-C) a bit more robust
644 - support for monitoring the total number of active disk streams
645 (new LSCP commands: GET TOTAL_STREAM_COUNT,
646 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
647
648 * AUDIO driver:
649 - added Windows ASIO low latency audio driver
650
651 * MIDI driver:
652 - added MME Windows MIDI driver
653
654 * LSCP server:
655 - added support for Windows style path / filenames, however with
656 forward slash path separators instead of backslash
657 (i.e. "C:/foo/bar.gig")
658 - allow naughty liblscp to send non-string device parameters within
659 apostrophes as well
660 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
661 "LIST FILE INSTRUMENTS <file>" and
662 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
663 about an arbitrary instrument file on the system where the sampler is
664 running on
665
666 Version 0.5.0 (15 October 2007)
667
668 * packaging changes:
669 - config.h is not going to be installed along with liblinuxsampler's
670 API header files anymore
671 - only the API relevant header (and source) files will be exported to
672 the Doxygen API documentation (explicitly listed in Doxyfile.in)
673 - added completely new XCode project files for Mac OSX which is now
674 capable to execute our autoconf environment, thus no need anymore
675 to maintain the compile time configuration file (osx/version.h) for
676 OSX manually (patch by Toshi Nagata)
677 - fixed buggy boolean --enable-foo / --disable-foo configure script
678 parameters
679 - global.h now only covers global definitions that are needed for the
680 C++ API header files, all implementation internal global definitions
681 are now in global_private.h
682 - atomic.h is not exposed to the C++ API anymore
683 - no need to include config.h anymore for using LS's API header files
684 - fixed warnings in API doc generation
685
686 * general changes:
687 - replaced the old, confusing MIDI program change mechanism by a
688 flexible MIDI instrument mapper which allows to map arbitrary
689 (MIDI bank, MIDI program) pairs with arbitrary
690 (engine type, instrument file, file index) triplets which will be
691 loaded on the respective channel when such MIDI program change
692 messages arrive, beside that, each entry allows to define a life-time
693 strategy for the instrument, so the user can define whether the
694 instrument should i.e. be permanently loaded (to be able to switch
695 quickly among sounds) or i.e. loaded just on demand when the
696 respective program change arrives (to safe RAM space), as well as a
697 global volume factor for each entry, so the user can adjust the volume
698 dynamic of his mapped instrument collection without having to modify
699 the instrument files, also one can manage arbitrary amount of such
700 MIDI instrument maps and assign each sampler channel individually
701 a certain map, so that i.e. separation of normal instruments and
702 drumkits is possible
703 - new notification events for tracking changes to audio/MIDI devices,
704 MIDI instrument maps, MIDI instruments, FX sends, global volume.
705 - sampler was limited to load max. 200 instruments in the background
706 due to a constant size RingBuffer FIFO which is now replaced by a
707 dynamic (unlimited) size std::list FIFO
708 - added FX sends, these allow to route audio signals to arbitrary audio
709 output channels for being processed by external effect processors
710 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
711 controllers
712 - global (sampler wide) volume can now be controlled at runtime
713 - Implemented new, improved notification system
714 - fixed compilation errors regarding OSX
715 (patch by Toshi Nagata)
716 - implemented instruments database
717 - added support for escape sequences to the instruments database
718 - added highly experimental support for on-the-fly instrument editing
719 within the sampler's process (by using instrument editor plugins),
720 you'll notice the new "Registered instrument editors:" message on
721 startup, added a new LSCP command:
722 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
723 to spawn a matching instrument editor for the instrument on the
724 given sampler channel, the plugin path can be overridden at compile
725 time with ./configure --enable-plugin-dir=/some/dir
726 - added experimental code for synchronizing instrument editors hosted
727 in the sampler's process to safely edit instruments while playing
728 without a crash (hopefully) by either suspending single regions
729 wherever possible or if unavoidable whole engine(s)
730 - fixed several issues in fundamental "Thread" class: set scheduling
731 policy and priority on thread level, set a minimum stack size for
732 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
733 threads simply inherited properties of starting thread instead of
734 setting their own policy and priority
735 - minor fix in our automatic stack trace mechanism on crashes, the
736 main process did not wait for the stack trace process to finish
737 its output
738 - fixed some minor memory leaks
739 - reenabled assembly features support, at the moment only for
740 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
741 - minor assembly fix in x86 features detection (don't use the PIC
742 register, to avoid relocations in the text segment at runtime)
743 - POSIX callback functions of Thread.h are hidden
744
745 * MIDI driver:
746 - dispatch bank select (MSB and LSB) messages
747
748 * audio driver:
749 - the ALSA audio output driver parameters now reflect the correct
750 parameter value ranges for the respective selected sound card
751 (patch by Till Wimmer, a bit fixed and extended)
752
753 * Gigasampler format engine:
754 - if a filter is used and EG2 finishes before EG1, let the voice
755 die when EG2 has finished (this fixes a problem with clicks and
756 voice starvation for some gigs)
757 - playback is no longer disabled during instrument loading
758 - all notes playing on a channel that changes its instrument keep
759 playing with the old instrument until they get a note off
760 command
761 - EG fix: a release value of zero could cause noises or crash
762 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
763 - EG fine tuning: when attack is zero the EG starts at a level
764 above max sustain level, which means that there is a decay phase
765 even if sustain is 100%
766 - more EG fixes: the level could sometimes go below zero and cause
767 noises or crashes
768 - minor fix of EGDecay (patch by Toshi Nagata)
769 - fixed compiler error when --enable-override-filter-type was
770 supplied to the configure script (fixes #46)
771 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
772 instead of a fix value
773 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
774 127 (solo mode) only kill voices if the respective mode really
775 changed
776
777 * LSCP server:
778 - fixed compile time error for old Bison versions
779 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
780 - parser now supports extended ASCII character set
781 (up to ASCII code 255, i.e. includes now umlauts and accents)
782 - filename arguments in LSCP commands now allow to use escape
783 sequences, that is directly literal as one of: \', \", \\, \n, \r,
784 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
785 code value like \xf2) (fixes bug #24)
786 - the following LSCP commands now also support escape sequences for at
787 least one of their text-based parameters (i.e. name, description):
788 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
789 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
790 "SET DB_INSTRUMENT_DIRECTORY NAME",
791 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
792 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
793 "FIND DB_INSTRUMENT_DIRECTORIES"
794 - returns verbose syntax errors (line and column where syntax error
795 occured, the unexpected character and the actually expected, possible
796 character(s), the latter only if less than 5 possibilities)
797 - made sure that LSCP syntax is not affected by gigedit locale
798 settings
799 - bugfix regarding strings parameter lists: all comma separated lists
800 of strings were treated as being one string containing commas
801 (fixes #57)
802
803 * Bug fixes:
804 - fixed crash occurring on certain LSCP scripts (Bug 39)
805 - another thread safety fix for lscp "load engine" and "set
806 channel audio output device"
807 - fixed a crash which occurs when reassigning the same engine
808 on a sampler channel with connected MIDI device
809 - fixed a crash which occurs when changing the number of ports of a MIDI
810 device connected to a sampler channel to number less then or equal
811 to the index of the port to which the sampler channel is connected.
812 - The previous bindings were not been disconnected when altering
813 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
814 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
815 - The active stream/voice count statistic was incorrect.
816 - notification events were not been sent for some sampler
817 channel changes
818 - added default min and max values to restrict the number of allowed
819 audio output channels and MIDI input ports
820 - the connection to the PCM interface is now closed when destroying
821 an audio output device
822 - files with slash in their path or filename could not be loaded
823
824 * test cases:
825 - updated and fixed (haven't been touched in a while)
826
827 Version 0.4.0 (24 November 2006)
828
829 * packaging changes:
830 - changed deprecated copyright attribute to license; added ldconfig
831 to post-(un)install steps; added devel package for liblinuxsampler;
832 to linuxsampler.spec (RPM)
833 - install necessary development header files for allowing 3rd party
834 applications to link against liblinuxsampler
835 - liblinuxsampler's API documentation can be generated with 'make docs'
836 (Doxygen required)
837 - added benchmark to automatically detect the best triangle LFO
838 implementation (currently either an integer math solution or a
839 di-harmonic approximation), automatic detection can be overriden
840 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
841 configure script argument though (mandatory for cross-compilation)
842 - do not automatically pick optimized gcc flags if the user already
843 provided some on his own (as CXXFLAGS)
844 - added compile time option to disable processing of All-Notes-Off MIDI
845 messages
846 - added compile time options to allow disabling the various audio and
847 MIDI drivers
848 - fixed automatic GCC CPU switch detection on PPC
849 (patch by Ebrahim Mayat)
850
851 * Gigasampler format engine:
852 - extensive synthesis optimization
853 (reimplementation of EGs and LFO(s), removed synthesis parameter
854 prerendering and the synthesis parameter matrix in general, splitting
855 each audio fragment into subfragments now where each subfragment uses
856 constant pitch and filter coefficients. The volume coefficient is
857 linearly interpolated inside a subfragment, unless
858 --disable-interpolate-volume is set.)
859 - fine tuning of the EG modulation parameters
860 - improved filter cutoff calculation by adding support for the
861 following gig parameters: Cutoff freq (used when no cutoff
862 controller is defined), Control invert, Minimum cutoff, Velocity
863 curve and Velocity range. The keyboard tracking now scales
864 cutoff frequency instead of resonance.
865 - added support for gig parameter Resonance.
866 - fixed bug in sysex handling (patch by Juan Linietsky)
867 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
868 which can be overridden with --enable-global-attenuation
869 - EG fixes: made the length of "attack hold" stage more
870 accurate. Release stage can now start before attack stage
871 ends. Cancel release didn't work when sustain was zero. Attack
872 time now has a minimal value to prevent clicks.
873 - fixed pitch changes larger than one octave
874 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
875 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
876 all modes can be altered via standard GM messages, that is CC5 for
877 altering portamento time, CC65 for enabling / disabling portamento
878 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
879 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
880 parameter) and crossfade
881 - added support for the "attenuation controller threshold" gig
882 parameter
883 - added smoothing of volume changes caused by control change
884 messages
885 - sample loop parameters are now taken from the DimensionRegion
886 instead of the wave chunk
887 - fixed keyswitching for v3 gigs with a number of keyswitch splits
888 not equal to a power of two
889 - reimplementation of the filter algorithm. The new filter is more
890 accurate and supports all gig filter types, including bandreject
891 and lowpass turbo.
892 - real support for 24 bit samples - samples are not truncated to
893 16 bits anymore
894 - support for aftertouch (channel pressure, not polyphonic
895 aftertouch)
896 - LFO1 behaviour fixed (dampening from max volume instead of
897 amplifying from 0)
898
899 * LSCP server:
900 - fixed application exit on broken pipe error (fixes bug #20)
901 - fixed the notification messages delay due to lack of
902 network activity (fixes bug #26)
903 - fixed parser bug which occured on space(s) within device parameters
904 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
905
906 * audio driver:
907 - added aRts audio output driver (by no means RT safe)
908
909 * MIDI driver:
910 - fixed legacy sysex code which caused dispatching of MIDI SysEx
911 messages several times instead of once
912 - API extension for MIDI drivers which already supply exact time stamps
913 for events (i.e. for offline rendering based MIDI drivers)
914 - added checks for bad MIDI data
915
916 * linuxsampler application:
917 - show available sampler engine types on startup
918
919 * general changes:
920 - support for muting sampler channels and solo mode of the same, two new
921 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
922 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
923 introduced for this, the behavior is the same like on a mixer console
924 (patch by Grigor Iliev, a bit adjusted). Also added configure option
925 --enable-process-muted-channels which can be used to enable the
926 processing of muted channels.
927 - support for sostenuto pedal
928 - support for monitoring the total number of active voices
929 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
930 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
931 - fixed some memory management errors
932 - fixed some concurrency problems that could lead to crashes when
933 LSCP commands were executed
934 - fixed crash when instrument loading failed previously on the same
935 sampler channel (fixes bug #36)
936
937 Version 0.3.3 (15 July 2005)
938
939 * packaging changes:
940 - fixed compilation with gcc 4.0
941
942 * Gigasampler format engine:
943 - LFO preprocessing was performed even though the respective LFO was
944 disabled by the instrument patch (minor efficiency fix)
945 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
946 for volume ramp downs in the same fragment (needed for current voice
947 stealing implementation) then simply inform the user with a warning
948 about possible click sounds and reduce the volume ramp down
949 appropriately instead of cancelling the audio device connection
950
951 Version 0.3.2 (24 June 2005)
952
953 * packaging changes:
954 - updated autotools build files to compile on OS X
955 (conditional compilation of CoreMIDI and MidiShare drivers)
956 - hand-crafted assembly optimization code can be disabled with
957 './configure --disable-asm' (definitely not recommended)
958 - fixed 'make dist' rule to include all necessary files
959 - require automake (>= 1.5) for 'make -f Makefile.cvs'
960 (due to 'dist-bzip2' automake option)
961
962 * Gigasampler format engine:
963 - support for the gig parameters for "release velocity response" curves
964 - fine tuning of the EGADSR envelope
965 - volume of release triggered samples now depends on note-on velocity,
966 note length and gig parameter "release trigger decay" instead of
967 note-off velocity.
968 - revised voice stealing
969 (fixes crash and endless loop caused by voice stealing)
970 - don't reset scale tuning on instrument or audio output device change
971 - handle key group conflicts right at the beginning of each fragment
972 instead of when the respective voice is actually launched
973 (fixes undefined behavior if stolen voices belonged to a key group -
974 this case was followed by a "killed voice survived" error message)
975 - fixed minor issue with null/silence samples
976 (those stole voices even though they don't need a voice at all which
977 resulted in "voice stealing didn't work out" messages)
978 - don't reset volume, pan, pitch and MIDI controller values on
979 instrument or audio output device change
980
981 * LSCP server:
982 - fixed some crashes (patch by Grigor Iliev, fixes #19)
983 - fixed LSCP event "CHANNEL_INFO" notification
984 (e.g. did not notify on volume changes or MIDI program change events)
985
986 * linuxsampler application:
987 - added command line parameters --lscp-addr and --lscp-port to override
988 default IP address and port of LSCP server
989
990 Version 0.3.1 (24 May 2005)
991
992 * initial release
