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

308 - ASIO driver fixes for newer gcc versions (fix from PortAudio)
309 - JACK audio: react on sample rate changes.
310 - JACK audio: react on buffer size changes.

368 after MIDI/audio device creation failure
369 - When creating MIDI instrument map entries with "PERSISTENT" type, the
370 instruments were uselessly precached with zero samples, however it still
371 took the full preloading time and on 1st program change the respective

395
396 * packaging changes:
397 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

417 - bugfix: on some POSIX systems instrument editor plugins refused to
418 load as we used a non-portable Linux specific struct field
419 (fixes bug #70, patch by Ronald Baljeu)
420 - fixed endless loop which occured when loading an instrument editor
421 plugin DLL on Windows systems failed
422 - fixed memory leaks that occurred when liblinuxsampler was unloaded
423 - optimized the SynchronizedConfig class so it doesn't wait
424 unnecessarily long after an update
425 - added support for notifying instrument editors on note-on / note-off
426 events (e.g. to highlight the pressed keys on the virtual keyboard
427 of gigedit)
428 - added support for triggering notes by instrument editors (see above)
429 - be verbose on DLL load errors (on Linux)
430 - fixed di-harmonic triangle LFO implementation (this LFO implementation
431 is only used by very few systems, most pick the int math
432 implementation, which is usually faster)
433 - fixes for audio drivers with varying buffer sizes
434 - experimental support for running LinuxSampler as a DSSI, LV2 and
435 VST plugin
436 - notification events for stream/voice count statistics are now sent
437 only when there are actual changes
438 - added memory ordering constraints to improve stability on
439 multi-core and multi-cpu systems
440 - maximum voices and disk streams can now be altered at runtime
441 - fixed CPU feature detection on x86_64 (maybe fixes #108)
442 - automatic stacktrace mechanism is now turned off by default and can
443 be switched on by command line option "--stacktrace" (the automatic
444 stacktrace mechanism seems to be broken on most systems at the moment)
445 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
446 a pointer to the launched InstrumentEditor object
447 - added optional 3rd party user data parameter for following
448 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
449 InstrumentEditor::Launch(),
450 InstrumentManager::LaunchInstrumentEditor()
451 - theoretical fix: made SynchronizedConfig follow C++0x memory
452 model more strictly
453 - fixes for using large audio device buffers
454 - Windows: add the installation directory to the DLL search path
455 when loading an editor plugin (solves problems with VST and
456 gigedit on systems with other GTK versions installed)
457
458 * audio driver:
459 - removed the nonsense audio channel constraint (which was hard coded to
460 max. 100 audio channels) for most audio drivers
461 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
462 opposed to the LSCP specs
463 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
464 reflected the wrong value
465 - fixed a memory management bug in ASIO driver
466 - Makefile fix: JACK_CFLAGS wasn't used
467 - JACK: use jack_client_open instead of the deprecated
468 jack_client_new
469 - added (experimental) CoreAudio driver
470 - applied old fixes to the ASIO driver that were included in the
471 previous binary release but accidentally never committed to CVS
472 (fixes #117)
473 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
474 win64)
475 - VST: added support for sample rate and buffer size changes
476 - VST: close editor (Fantasia) when the VST is removed
477 - VST: avoid opening Fantasia more than once for each VST instance
478 - VST: export main function as "main" on Linux too (fix for
479 energyXT)
480 - VST: changed number of output channels from one stereo to 16
481 stereo
482 - added channel routing, fxsends and midi maps to the settings
483 stored in the plugin state
484 - performance optimization of AudioChannel::MixTo() and
485 AudioChannel::CopyTo() methods using GCC vector exensions
486 (if available)
487 - ASIO fixes: avoid initializing the device twice, avoid throwing
488 exception when getting parameters from a disconnected device
489
490 * MIDI driver:
491 - added JACK MIDI driver
492 - dispatch bank select as ordinary CC as well, the user might seriously
493 want to (mis)use it for some purpose ("fixed" in all current MIDI
494 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
495 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
496 CoreMidi or AU
497 - fixed mingw-w64 compilation error in MME driver
498 - made program change handling in MIDI thread real-time safe by
499 moving the logic to a non-RT thread
500 - fixed minor memory leak in ALSA driver
501
502 * instruments database:
503 - avoid time consuming samples scanning when adding instruments
504 to the instruments database
505 - added support for handling lost files in the instruments database
506 - Implemented option for adding instruments in separate directories
507 in the instruments database
508 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
509 - work-around for missing fnmatch function on Windows to make
510 instrument database compilable
511 - added instrument database support on Windows
512 works with both standalone mode and VST plugin.
513 the instruments DB file is located in
514 %USERPROFILE%\.linuxsampler\instruments.db which allows different
515 databases for each windows user
516 if no DB is present it automatically creates the .linuxsampler subdir
517 and then creates an empty DB
518 - fixed recursive import, which was broken on Windows
519
520 * Gigasampler format engine:
521 - fixed a memory leak that could happen when a channel was deleted
522 while notes were playing
523 - made it possible to load an instrument even if the audio thread
524 isn't running
525 - added partial support for the "Controller Triggered" MIDI rule,
526 enough for piano gigs with pedal noise samples
527 - minor fix: only mark FX sends as being modified if really the
528 respective FX send MIDI controller was used
529 - added support for GM global device volume SysEx message
530 (can be selected at compile time to either apply globally to the
531 whole sampler [default] or only to the sampler channels that are
532 connected to the respective MIDI input port the SysEx message arrived
533 on)
534 - bugfix: notes triggered at position 0 in the audio buffer were
535 sometimes wrongly killed in the same buffer, causing no sound to
536 be played
537 - added support for chromatic / drumkit mode Roland GS Sysex message
538 which is usally used to switch a part between chromatic sounds and
539 drumkit sounds (as opposed to their common default setting of MIDI
540 part 10 being a drumkit part and all other ones chromatic parts), in
541 LS however one can switch between the first 16 MIDI instrument maps
542 defined for the sampler
543 - made it possible to create multiple sample channels even if the
544 audio thread isn't running
545 - fixed crash when removing channel with active voices (#116)
546 - bugfix: on sample reference changes (instrument editor), only
547 un-cache the respective sample if it's really not used by any
548 sampler engine anymore
549 - re-cache samples in case they were changed by an instrument editor,
550 e.g. when a sample was added while playing (#82)
551 - fixed hanging notes which occured when note-off event had the exact
552 same time stamp as the voice's note-on event and occured both in the
553 same audio fragment cycle (fixes bug #112)
554 - added support for the "fine tune" and "pitch bend range"
555 instrument-level gig parameters
556 - fixed minor artifacts in pitch bend handling
557 - added support for GS Reset SysEx message
558 - allow gig files to use unlimited downward pitch shifting
559 - added a limit check for upward pitch shifting
560 - bugfix: sometimes, when playing a note twice fast, the second
561 note was silent
562 - fixed crash happening when a pitch bend event arrived at the
563 same time a new instrument was loading
564
565 * LSCP server:
566 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
567 react on MIDI data arriving on certain sampler channels (so far only
568 Note-On and Note-Off events are sent via this LSCP event)
569 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
570 react on MIDI data arriving on certain MIDI input devices (so far only
571 Note-On and Note-Off events are sent via this LSCP event)
572 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
573 SET DB_INSTRUMENT FILE_PATH
574 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
575 frontends to send MIDI messages to specific sampler channel
576 - added two additional fields to GET FILE INSTRUMENT INFO command -
577 KEY_BINDINGS and KEYSWITCH_BINDINGS
578 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
579 was incorrect
580 - Optimized the retrieval of the MIDI instrument mappings
581 - added new LSCP command "SET VOICES" to globally alter the maximum
582 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
583 be triggered respectively
584 - added new LSCP command "SET STREAMS" to globally alter the maximum
585 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
586 which will be triggered respectively
587 - bugfix: retry if "select" returns EINTR (this fixes a crash when
588 a gigedit file dialog is opened)
589 - close all connections when LSCPServer is deleted
590 - hard close of all sockets on exit
591 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
592 driver
593
594 * Bug fixes:
595 - fixed a crash which occurs when removing a sampler channel waiting
596 to start instrument loading after another channel
597 - fixed a crash which occurs when removing a sampler channel with
598 instrument loading in progress (bug #113)
599 - fixed termination caused by uncaught exception when adding MIDI
600 instrument with PERSISTENT load mode
601 - fixed possible iterator invalidations when resetting the sampler
602 - fixed memory leaks when issuing the following LSCP commands:
603 GET AUDIO_OUTPUT_DRIVER INFO
604 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
605 GET MIDI_INPUT_DRIVER INFO
606 GET MIDI_INPUT_DRIVER_PARAMETER INFO
607 - fixed possible compilation error when sqlite is not present
608 - fixed orphaned pointers when setting maximum voices limit (bug #118)
609 - fixed crash when changing the audio output device of a sampler
610 channel with loaded instrument and start playing notes
611 - fixed endless loop in Engine::SuspendAll() (bug #120)
612 - fixed a low-level atomic load function that was broken on 64-bit
613 PowerPC, which probably could cause crashes on that platform
614 - fixed a memory management error which could cause a crash when a
615 plugin was unloaded
616 - bugfix: two private structs had the same name, which could cause
617 problems if the linker chose the wrong constructor
618 - fixed low-level ConditionServer usage bug that caused lockups on
619 Windows
620
621
622 Version 0.5.1 (6 December 2007)
623
624 * packaging changes:
625 - added autoconf checks for pthread library
626 - added autoconf check for pthread bug found on certain NPTL-enabled
627 glibc versions (see Gentoo bug report #194076)
628 - added autoconf checks for MS Windows
629
630 * general changes:
631 - bugfix: the thread used by an editor plugin didn't die when the
632 editor closed
633 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
634 out all the space. operator--() did not apply size_mask after
635 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
636 order to avoid problems with the _NonVolatileReader functions.
637 - bugfix: Stream.h: added a missing divide by BytesPerSample in
638 GetWriteSpace(). Since this function is currently only used in
639 the stream's qsort() compare function, it didn't trigger any
640 bugs.
641 - Resampler.h, Synthesizer.h: cubic interpolation now works in
642 24bit mode too. Faster method to read 24bit words on little
643 endian machines (x86): replaced 3 byte reads + shifts with a 1
644 unaligned 32bit read and shift
645 - experimental support for MS Windows (MIDI input via MME, AUDIO
646 output via ASIO)
647 - made handling of SIGINT signal (Ctrl-C) a bit more robust
648 - support for monitoring the total number of active disk streams
649 (new LSCP commands: GET TOTAL_STREAM_COUNT,
650 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
651
652 * AUDIO driver:
653 - added Windows ASIO low latency audio driver
654
655 * MIDI driver:
656 - added MME Windows MIDI driver
657
658 * LSCP server:
659 - added support for Windows style path / filenames, however with
660 forward slash path separators instead of backslash
661 (i.e. "C:/foo/bar.gig")
662 - allow naughty liblscp to send non-string device parameters within
663 apostrophes as well
664 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
665 "LIST FILE INSTRUMENTS <file>" and
666 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
667 about an arbitrary instrument file on the system where the sampler is
668 running on
669
670 Version 0.5.0 (15 October 2007)
671
672 * packaging changes:
673 - config.h is not going to be installed along with liblinuxsampler's
674 API header files anymore
675 - only the API relevant header (and source) files will be exported to
676 the Doxygen API documentation (explicitly listed in Doxyfile.in)
677 - added completely new XCode project files for Mac OSX which is now
678 capable to execute our autoconf environment, thus no need anymore
679 to maintain the compile time configuration file (osx/version.h) for
680 OSX manually (patch by Toshi Nagata)
681 - fixed buggy boolean --enable-foo / --disable-foo configure script
682 parameters
683 - global.h now only covers global definitions that are needed for the
684 C++ API header files, all implementation internal global definitions
685 are now in global_private.h
686 - atomic.h is not exposed to the C++ API anymore
687 - no need to include config.h anymore for using LS's API header files
688 - fixed warnings in API doc generation
689
690 * general changes:
691 - replaced the old, confusing MIDI program change mechanism by a
692 flexible MIDI instrument mapper which allows to map arbitrary
693 (MIDI bank, MIDI program) pairs with arbitrary
694 (engine type, instrument file, file index) triplets which will be
695 loaded on the respective channel when such MIDI program change
696 messages arrive, beside that, each entry allows to define a life-time
697 strategy for the instrument, so the user can define whether the
698 instrument should i.e. be permanently loaded (to be able to switch
699 quickly among sounds) or i.e. loaded just on demand when the
700 respective program change arrives (to safe RAM space), as well as a
701 global volume factor for each entry, so the user can adjust the volume
702 dynamic of his mapped instrument collection without having to modify
703 the instrument files, also one can manage arbitrary amount of such
704 MIDI instrument maps and assign each sampler channel individually
705 a certain map, so that i.e. separation of normal instruments and
706 drumkits is possible
707 - new notification events for tracking changes to audio/MIDI devices,
708 MIDI instrument maps, MIDI instruments, FX sends, global volume.
709 - sampler was limited to load max. 200 instruments in the background
710 due to a constant size RingBuffer FIFO which is now replaced by a
711 dynamic (unlimited) size std::list FIFO
712 - added FX sends, these allow to route audio signals to arbitrary audio
713 output channels for being processed by external effect processors
714 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
715 controllers
716 - global (sampler wide) volume can now be controlled at runtime
717 - Implemented new, improved notification system
718 - fixed compilation errors regarding OSX
719 (patch by Toshi Nagata)
720 - implemented instruments database
721 - added support for escape sequences to the instruments database
722 - added highly experimental support for on-the-fly instrument editing
723 within the sampler's process (by using instrument editor plugins),
724 you'll notice the new "Registered instrument editors:" message on
725 startup, added a new LSCP command:
726 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
727 to spawn a matching instrument editor for the instrument on the
728 given sampler channel, the plugin path can be overridden at compile
729 time with ./configure --enable-plugin-dir=/some/dir
730 - added experimental code for synchronizing instrument editors hosted
731 in the sampler's process to safely edit instruments while playing
732 without a crash (hopefully) by either suspending single regions
733 wherever possible or if unavoidable whole engine(s)
734 - fixed several issues in fundamental "Thread" class: set scheduling
735 policy and priority on thread level, set a minimum stack size for
736 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
737 threads simply inherited properties of starting thread instead of
738 setting their own policy and priority
739 - minor fix in our automatic stack trace mechanism on crashes, the
740 main process did not wait for the stack trace process to finish
741 its output
742 - fixed some minor memory leaks
743 - reenabled assembly features support, at the moment only for
744 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
745 - minor assembly fix in x86 features detection (don't use the PIC
746 register, to avoid relocations in the text segment at runtime)
747 - POSIX callback functions of Thread.h are hidden
748
749 * MIDI driver:
750 - dispatch bank select (MSB and LSB) messages
751
752 * audio driver:
753 - the ALSA audio output driver parameters now reflect the correct
754 parameter value ranges for the respective selected sound card
755 (patch by Till Wimmer, a bit fixed and extended)
756
757 * Gigasampler format engine:
758 - if a filter is used and EG2 finishes before EG1, let the voice
759 die when EG2 has finished (this fixes a problem with clicks and
760 voice starvation for some gigs)
761 - playback is no longer disabled during instrument loading
762 - all notes playing on a channel that changes its instrument keep
763 playing with the old instrument until they get a note off
764 command
765 - EG fix: a release value of zero could cause noises or crash
766 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
767 - EG fine tuning: when attack is zero the EG starts at a level
768 above max sustain level, which means that there is a decay phase
769 even if sustain is 100%
770 - more EG fixes: the level could sometimes go below zero and cause
771 noises or crashes
772 - minor fix of EGDecay (patch by Toshi Nagata)
773 - fixed compiler error when --enable-override-filter-type was
774 supplied to the configure script (fixes #46)
775 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
776 instead of a fix value
777 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
778 127 (solo mode) only kill voices if the respective mode really
779 changed
780
781 * LSCP server:
782 - fixed compile time error for old Bison versions
783 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
784 - parser now supports extended ASCII character set
785 (up to ASCII code 255, i.e. includes now umlauts and accents)
786 - filename arguments in LSCP commands now allow to use escape
787 sequences, that is directly literal as one of: \', \", \\, \n, \r,
788 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
789 code value like \xf2) (fixes bug #24)
790 - the following LSCP commands now also support escape sequences for at
791 least one of their text-based parameters (i.e. name, description):
792 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
793 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
794 "SET DB_INSTRUMENT_DIRECTORY NAME",
795 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
796 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
797 "FIND DB_INSTRUMENT_DIRECTORIES"
798 - returns verbose syntax errors (line and column where syntax error
799 occured, the unexpected character and the actually expected, possible
800 character(s), the latter only if less than 5 possibilities)
801 - made sure that LSCP syntax is not affected by gigedit locale
802 settings
803 - bugfix regarding strings parameter lists: all comma separated lists
804 of strings were treated as being one string containing commas
805 (fixes #57)
806
807 * Bug fixes:
808 - fixed crash occurring on certain LSCP scripts (Bug 39)
809 - another thread safety fix for lscp "load engine" and "set
810 channel audio output device"
811 - fixed a crash which occurs when reassigning the same engine
812 on a sampler channel with connected MIDI device
813 - fixed a crash which occurs when changing the number of ports of a MIDI
814 device connected to a sampler channel to number less then or equal
815 to the index of the port to which the sampler channel is connected.
816 - The previous bindings were not been disconnected when altering
817 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
818 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
819 - The active stream/voice count statistic was incorrect.
820 - notification events were not been sent for some sampler
821 channel changes
822 - added default min and max values to restrict the number of allowed
823 audio output channels and MIDI input ports
824 - the connection to the PCM interface is now closed when destroying
825 an audio output device
826 - files with slash in their path or filename could not be loaded
827
828 * test cases:
829 - updated and fixed (haven't been touched in a while)
830
831 Version 0.4.0 (24 November 2006)
832
833 * packaging changes:
834 - changed deprecated copyright attribute to license; added ldconfig
835 to post-(un)install steps; added devel package for liblinuxsampler;
836 to linuxsampler.spec (RPM)
837 - install necessary development header files for allowing 3rd party
838 applications to link against liblinuxsampler
839 - liblinuxsampler's API documentation can be generated with 'make docs'
840 (Doxygen required)
841 - added benchmark to automatically detect the best triangle LFO
842 implementation (currently either an integer math solution or a
843 di-harmonic approximation), automatic detection can be overriden
844 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
845 configure script argument though (mandatory for cross-compilation)
846 - do not automatically pick optimized gcc flags if the user already
847 provided some on his own (as CXXFLAGS)
848 - added compile time option to disable processing of All-Notes-Off MIDI
849 messages
850 - added compile time options to allow disabling the various audio and
851 MIDI drivers
852 - fixed automatic GCC CPU switch detection on PPC
853 (patch by Ebrahim Mayat)
854
855 * Gigasampler format engine:
856 - extensive synthesis optimization
857 (reimplementation of EGs and LFO(s), removed synthesis parameter
858 prerendering and the synthesis parameter matrix in general, splitting
859 each audio fragment into subfragments now where each subfragment uses
860 constant pitch and filter coefficients. The volume coefficient is
861 linearly interpolated inside a subfragment, unless
862 --disable-interpolate-volume is set.)
863 - fine tuning of the EG modulation parameters
864 - improved filter cutoff calculation by adding support for the
865 following gig parameters: Cutoff freq (used when no cutoff
866 controller is defined), Control invert, Minimum cutoff, Velocity
867 curve and Velocity range. The keyboard tracking now scales
868 cutoff frequency instead of resonance.
869 - added support for gig parameter Resonance.
870 - fixed bug in sysex handling (patch by Juan Linietsky)
871 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
872 which can be overridden with --enable-global-attenuation
873 - EG fixes: made the length of "attack hold" stage more
874 accurate. Release stage can now start before attack stage
875 ends. Cancel release didn't work when sustain was zero. Attack
876 time now has a minimal value to prevent clicks.
877 - fixed pitch changes larger than one octave
878 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
879 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
880 all modes can be altered via standard GM messages, that is CC5 for
881 altering portamento time, CC65 for enabling / disabling portamento
882 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
883 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
884 parameter) and crossfade
885 - added support for the "attenuation controller threshold" gig
886 parameter
887 - added smoothing of volume changes caused by control change
888 messages
889 - sample loop parameters are now taken from the DimensionRegion
890 instead of the wave chunk
891 - fixed keyswitching for v3 gigs with a number of keyswitch splits
892 not equal to a power of two
893 - reimplementation of the filter algorithm. The new filter is more
894 accurate and supports all gig filter types, including bandreject
895 and lowpass turbo.
896 - real support for 24 bit samples - samples are not truncated to
897 16 bits anymore
898 - support for aftertouch (channel pressure, not polyphonic
899 aftertouch)
900 - LFO1 behaviour fixed (dampening from max volume instead of
901 amplifying from 0)
902
903 * LSCP server:
904 - fixed application exit on broken pipe error (fixes bug #20)
905 - fixed the notification messages delay due to lack of
906 network activity (fixes bug #26)
907 - fixed parser bug which occured on space(s) within device parameters
908 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
909
910 * audio driver:
911 - added aRts audio output driver (by no means RT safe)
912
913 * MIDI driver:
914 - fixed legacy sysex code which caused dispatching of MIDI SysEx
915 messages several times instead of once
916 - API extension for MIDI drivers which already supply exact time stamps
917 for events (i.e. for offline rendering based MIDI drivers)
918 - added checks for bad MIDI data
919
920 * linuxsampler application:
921 - show available sampler engine types on startup
922
923 * general changes:
924 - support for muting sampler channels and solo mode of the same, two new
925 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
926 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
927 introduced for this, the behavior is the same like on a mixer console
928 (patch by Grigor Iliev, a bit adjusted). Also added configure option
929 --enable-process-muted-channels which can be used to enable the
930 processing of muted channels.
931 - support for sostenuto pedal
932 - support for monitoring the total number of active voices
933 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
934 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
935 - fixed some memory management errors
936 - fixed some concurrency problems that could lead to crashes when
937 LSCP commands were executed
938 - fixed crash when instrument loading failed previously on the same
939 sampler channel (fixes bug #36)
940
941 Version 0.3.3 (15 July 2005)
942
943 * packaging changes:
944 - fixed compilation with gcc 4.0
945
946 * Gigasampler format engine:
947 - LFO preprocessing was performed even though the respective LFO was
948 disabled by the instrument patch (minor efficiency fix)
949 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
950 for volume ramp downs in the same fragment (needed for current voice
951 stealing implementation) then simply inform the user with a warning
952 about possible click sounds and reduce the volume ramp down
953 appropriately instead of cancelling the audio device connection
954
955 Version 0.3.2 (24 June 2005)
956
957 * packaging changes:
958 - updated autotools build files to compile on OS X
959 (conditional compilation of CoreMIDI and MidiShare drivers)
960 - hand-crafted assembly optimization code can be disabled with
961 './configure --disable-asm' (definitely not recommended)
962 - fixed 'make dist' rule to include all necessary files
963 - require automake (>= 1.5) for 'make -f Makefile.cvs'
964 (due to 'dist-bzip2' automake option)
965
966 * Gigasampler format engine:
967 - support for the gig parameters for "release velocity response" curves
968 - fine tuning of the EGADSR envelope
969 - volume of release triggered samples now depends on note-on velocity,
970 note length and gig parameter "release trigger decay" instead of
971 note-off velocity.
972 - revised voice stealing
973 (fixes crash and endless loop caused by voice stealing)
974 - don't reset scale tuning on instrument or audio output device change
975 - handle key group conflicts right at the beginning of each fragment
976 instead of when the respective voice is actually launched
977 (fixes undefined behavior if stolen voices belonged to a key group -
978 this case was followed by a "killed voice survived" error message)
979 - fixed minor issue with null/silence samples
980 (those stole voices even though they don't need a voice at all which
981 resulted in "voice stealing didn't work out" messages)
982 - don't reset volume, pan, pitch and MIDI controller values on
983 instrument or audio output device change
984
985 * LSCP server:
986 - fixed some crashes (patch by Grigor Iliev, fixes #19)
987 - fixed LSCP event "CHANNEL_INFO" notification
988 (e.g. did not notify on volume changes or MIDI program change events)
989
990 * linuxsampler application:
991 - added command line parameters --lscp-addr and --lscp-port to override
992 default IP address and port of LSCP server
993
994 Version 0.3.1 (24 May 2005)
995
996 * initial release
