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.

366 it caused hanging threads on Windows
367 - Fixed possible crashes due to corrupted MIDI/audio device list
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
372 instrument was completely reloaded again.

395
396 Version 1.0.0 (31 July 2009)
397
398 * packaging changes:
399 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

416 - fix for new mingw-w64 version, which has usleep
417
418 * general changes:
419 - bugfix: on some POSIX systems instrument editor plugins refused to
420 load as we used a non-portable Linux specific struct field
421 (fixes bug #70, patch by Ronald Baljeu)
422 - fixed endless loop which occured when loading an instrument editor
423 plugin DLL on Windows systems failed
424 - fixed memory leaks that occurred when liblinuxsampler was unloaded
425 - optimized the SynchronizedConfig class so it doesn't wait
426 unnecessarily long after an update
427 - added support for notifying instrument editors on note-on / note-off
428 events (e.g. to highlight the pressed keys on the virtual keyboard
429 of gigedit)
430 - added support for triggering notes by instrument editors (see above)
431 - be verbose on DLL load errors (on Linux)
432 - fixed di-harmonic triangle LFO implementation (this LFO implementation
433 is only used by very few systems, most pick the int math
434 implementation, which is usually faster)
435 - fixes for audio drivers with varying buffer sizes
436 - experimental support for running LinuxSampler as a DSSI, LV2 and
437 VST plugin
438 - notification events for stream/voice count statistics are now sent
439 only when there are actual changes
440 - added memory ordering constraints to improve stability on
441 multi-core and multi-cpu systems
442 - maximum voices and disk streams can now be altered at runtime
443 - fixed CPU feature detection on x86_64 (maybe fixes #108)
444 - automatic stacktrace mechanism is now turned off by default and can
445 be switched on by command line option "--stacktrace" (the automatic
446 stacktrace mechanism seems to be broken on most systems at the moment)
447 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
448 a pointer to the launched InstrumentEditor object
449 - added optional 3rd party user data parameter for following
450 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
451 InstrumentEditor::Launch(),
452 InstrumentManager::LaunchInstrumentEditor()
453 - theoretical fix: made SynchronizedConfig follow C++0x memory
454 model more strictly
455 - fixes for using large audio device buffers
456 - Windows: add the installation directory to the DLL search path
457 when loading an editor plugin (solves problems with VST and
458 gigedit on systems with other GTK versions installed)
459
460 * audio driver:
461 - removed the nonsense audio channel constraint (which was hard coded to
462 max. 100 audio channels) for most audio drivers
463 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
464 opposed to the LSCP specs
465 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
466 reflected the wrong value
467 - fixed a memory management bug in ASIO driver
468 - Makefile fix: JACK_CFLAGS wasn't used
469 - JACK: use jack_client_open instead of the deprecated
470 jack_client_new
471 - added (experimental) CoreAudio driver
472 - applied old fixes to the ASIO driver that were included in the
473 previous binary release but accidentally never committed to CVS
474 (fixes #117)
475 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
476 win64)
477 - VST: added support for sample rate and buffer size changes
478 - VST: close editor (Fantasia) when the VST is removed
479 - VST: avoid opening Fantasia more than once for each VST instance
480 - VST: export main function as "main" on Linux too (fix for
481 energyXT)
482 - VST: changed number of output channels from one stereo to 16
483 stereo
484 - added channel routing, fxsends and midi maps to the settings
485 stored in the plugin state
486 - performance optimization of AudioChannel::MixTo() and
487 AudioChannel::CopyTo() methods using GCC vector exensions
488 (if available)
489 - ASIO fixes: avoid initializing the device twice, avoid throwing
490 exception when getting parameters from a disconnected device
491
492 * MIDI driver:
493 - added JACK MIDI driver
494 - dispatch bank select as ordinary CC as well, the user might seriously
495 want to (mis)use it for some purpose ("fixed" in all current MIDI
496 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
497 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
498 CoreMidi or AU
499 - fixed mingw-w64 compilation error in MME driver
500 - made program change handling in MIDI thread real-time safe by
501 moving the logic to a non-RT thread
502 - fixed minor memory leak in ALSA driver
503
504 * instruments database:
505 - avoid time consuming samples scanning when adding instruments
506 to the instruments database
507 - added support for handling lost files in the instruments database
508 - Implemented option for adding instruments in separate directories
509 in the instruments database
510 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
511 - work-around for missing fnmatch function on Windows to make
512 instrument database compilable
513 - added instrument database support on Windows
514 works with both standalone mode and VST plugin.
515 the instruments DB file is located in
516 %USERPROFILE%\.linuxsampler\instruments.db which allows different
517 databases for each windows user
518 if no DB is present it automatically creates the .linuxsampler subdir
519 and then creates an empty DB
520 - fixed recursive import, which was broken on Windows
521
522 * Gigasampler format engine:
523 - fixed a memory leak that could happen when a channel was deleted
524 while notes were playing
525 - made it possible to load an instrument even if the audio thread
526 isn't running
527 - added partial support for the "Controller Triggered" MIDI rule,
528 enough for piano gigs with pedal noise samples
529 - minor fix: only mark FX sends as being modified if really the
530 respective FX send MIDI controller was used
531 - added support for GM global device volume SysEx message
532 (can be selected at compile time to either apply globally to the
533 whole sampler [default] or only to the sampler channels that are
534 connected to the respective MIDI input port the SysEx message arrived
535 on)
536 - bugfix: notes triggered at position 0 in the audio buffer were
537 sometimes wrongly killed in the same buffer, causing no sound to
538 be played
539 - added support for chromatic / drumkit mode Roland GS Sysex message
540 which is usally used to switch a part between chromatic sounds and
541 drumkit sounds (as opposed to their common default setting of MIDI
542 part 10 being a drumkit part and all other ones chromatic parts), in
543 LS however one can switch between the first 16 MIDI instrument maps
544 defined for the sampler
545 - made it possible to create multiple sample channels even if the
546 audio thread isn't running
547 - fixed crash when removing channel with active voices (#116)
548 - bugfix: on sample reference changes (instrument editor), only
549 un-cache the respective sample if it's really not used by any
550 sampler engine anymore
551 - re-cache samples in case they were changed by an instrument editor,
552 e.g. when a sample was added while playing (#82)
553 - fixed hanging notes which occured when note-off event had the exact
554 same time stamp as the voice's note-on event and occured both in the
555 same audio fragment cycle (fixes bug #112)
556 - added support for the "fine tune" and "pitch bend range"
557 instrument-level gig parameters
558 - fixed minor artifacts in pitch bend handling
559 - added support for GS Reset SysEx message
560 - allow gig files to use unlimited downward pitch shifting
561 - added a limit check for upward pitch shifting
562 - bugfix: sometimes, when playing a note twice fast, the second
563 note was silent
564 - fixed crash happening when a pitch bend event arrived at the
565 same time a new instrument was loading
566
567 * LSCP server:
568 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
569 react on MIDI data arriving on certain sampler channels (so far only
570 Note-On and Note-Off events are sent via this LSCP event)
571 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
572 react on MIDI data arriving on certain MIDI input devices (so far only
573 Note-On and Note-Off events are sent via this LSCP event)
574 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
575 SET DB_INSTRUMENT FILE_PATH
576 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
577 frontends to send MIDI messages to specific sampler channel
578 - added two additional fields to GET FILE INSTRUMENT INFO command -
579 KEY_BINDINGS and KEYSWITCH_BINDINGS
580 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
581 was incorrect
582 - Optimized the retrieval of the MIDI instrument mappings
583 - added new LSCP command "SET VOICES" to globally alter the maximum
584 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
585 be triggered respectively
586 - added new LSCP command "SET STREAMS" to globally alter the maximum
587 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
588 which will be triggered respectively
589 - bugfix: retry if "select" returns EINTR (this fixes a crash when
590 a gigedit file dialog is opened)
591 - close all connections when LSCPServer is deleted
592 - hard close of all sockets on exit
593 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
594 driver
595
596 * Bug fixes:
597 - fixed a crash which occurs when removing a sampler channel waiting
598 to start instrument loading after another channel
599 - fixed a crash which occurs when removing a sampler channel with
600 instrument loading in progress (bug #113)
601 - fixed termination caused by uncaught exception when adding MIDI
602 instrument with PERSISTENT load mode
603 - fixed possible iterator invalidations when resetting the sampler
604 - fixed memory leaks when issuing the following LSCP commands:
605 GET AUDIO_OUTPUT_DRIVER INFO
606 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
607 GET MIDI_INPUT_DRIVER INFO
608 GET MIDI_INPUT_DRIVER_PARAMETER INFO
609 - fixed possible compilation error when sqlite is not present
610 - fixed orphaned pointers when setting maximum voices limit (bug #118)
611 - fixed crash when changing the audio output device of a sampler
612 channel with loaded instrument and start playing notes
613 - fixed endless loop in Engine::SuspendAll() (bug #120)
614 - fixed a low-level atomic load function that was broken on 64-bit
615 PowerPC, which probably could cause crashes on that platform
616 - fixed a memory management error which could cause a crash when a
617 plugin was unloaded
618 - bugfix: two private structs had the same name, which could cause
619 problems if the linker chose the wrong constructor
620 - fixed low-level ConditionServer usage bug that caused lockups on
621 Windows
622
623
624 Version 0.5.1 (6 December 2007)
625
626 * packaging changes:
627 - added autoconf checks for pthread library
628 - added autoconf check for pthread bug found on certain NPTL-enabled
629 glibc versions (see Gentoo bug report #194076)
630 - added autoconf checks for MS Windows
631
632 * general changes:
633 - bugfix: the thread used by an editor plugin didn't die when the
634 editor closed
635 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
636 out all the space. operator--() did not apply size_mask after
637 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
638 order to avoid problems with the _NonVolatileReader functions.
639 - bugfix: Stream.h: added a missing divide by BytesPerSample in
640 GetWriteSpace(). Since this function is currently only used in
641 the stream's qsort() compare function, it didn't trigger any
642 bugs.
643 - Resampler.h, Synthesizer.h: cubic interpolation now works in
644 24bit mode too. Faster method to read 24bit words on little
645 endian machines (x86): replaced 3 byte reads + shifts with a 1
646 unaligned 32bit read and shift
647 - experimental support for MS Windows (MIDI input via MME, AUDIO
648 output via ASIO)
649 - made handling of SIGINT signal (Ctrl-C) a bit more robust
650 - support for monitoring the total number of active disk streams
651 (new LSCP commands: GET TOTAL_STREAM_COUNT,
652 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
653
654 * AUDIO driver:
655 - added Windows ASIO low latency audio driver
656
657 * MIDI driver:
658 - added MME Windows MIDI driver
659
660 * LSCP server:
661 - added support for Windows style path / filenames, however with
662 forward slash path separators instead of backslash
663 (i.e. "C:/foo/bar.gig")
664 - allow naughty liblscp to send non-string device parameters within
665 apostrophes as well
666 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
667 "LIST FILE INSTRUMENTS <file>" and
668 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
669 about an arbitrary instrument file on the system where the sampler is
670 running on
671
672 Version 0.5.0 (15 October 2007)
673
674 * packaging changes:
675 - config.h is not going to be installed along with liblinuxsampler's
676 API header files anymore
677 - only the API relevant header (and source) files will be exported to
678 the Doxygen API documentation (explicitly listed in Doxyfile.in)
679 - added completely new XCode project files for Mac OSX which is now
680 capable to execute our autoconf environment, thus no need anymore
681 to maintain the compile time configuration file (osx/version.h) for
682 OSX manually (patch by Toshi Nagata)
683 - fixed buggy boolean --enable-foo / --disable-foo configure script
684 parameters
685 - global.h now only covers global definitions that are needed for the
686 C++ API header files, all implementation internal global definitions
687 are now in global_private.h
688 - atomic.h is not exposed to the C++ API anymore
689 - no need to include config.h anymore for using LS's API header files
690 - fixed warnings in API doc generation
691
692 * general changes:
693 - replaced the old, confusing MIDI program change mechanism by a
694 flexible MIDI instrument mapper which allows to map arbitrary
695 (MIDI bank, MIDI program) pairs with arbitrary
696 (engine type, instrument file, file index) triplets which will be
697 loaded on the respective channel when such MIDI program change
698 messages arrive, beside that, each entry allows to define a life-time
699 strategy for the instrument, so the user can define whether the
700 instrument should i.e. be permanently loaded (to be able to switch
701 quickly among sounds) or i.e. loaded just on demand when the
702 respective program change arrives (to safe RAM space), as well as a
703 global volume factor for each entry, so the user can adjust the volume
704 dynamic of his mapped instrument collection without having to modify
705 the instrument files, also one can manage arbitrary amount of such
706 MIDI instrument maps and assign each sampler channel individually
707 a certain map, so that i.e. separation of normal instruments and
708 drumkits is possible
709 - new notification events for tracking changes to audio/MIDI devices,
710 MIDI instrument maps, MIDI instruments, FX sends, global volume.
711 - sampler was limited to load max. 200 instruments in the background
712 due to a constant size RingBuffer FIFO which is now replaced by a
713 dynamic (unlimited) size std::list FIFO
714 - added FX sends, these allow to route audio signals to arbitrary audio
715 output channels for being processed by external effect processors
716 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
717 controllers
718 - global (sampler wide) volume can now be controlled at runtime
719 - Implemented new, improved notification system
720 - fixed compilation errors regarding OSX
721 (patch by Toshi Nagata)
722 - implemented instruments database
723 - added support for escape sequences to the instruments database
724 - added highly experimental support for on-the-fly instrument editing
725 within the sampler's process (by using instrument editor plugins),
726 you'll notice the new "Registered instrument editors:" message on
727 startup, added a new LSCP command:
728 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
729 to spawn a matching instrument editor for the instrument on the
730 given sampler channel, the plugin path can be overridden at compile
731 time with ./configure --enable-plugin-dir=/some/dir
732 - added experimental code for synchronizing instrument editors hosted
733 in the sampler's process to safely edit instruments while playing
734 without a crash (hopefully) by either suspending single regions
735 wherever possible or if unavoidable whole engine(s)
736 - fixed several issues in fundamental "Thread" class: set scheduling
737 policy and priority on thread level, set a minimum stack size for
738 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
739 threads simply inherited properties of starting thread instead of
740 setting their own policy and priority
741 - minor fix in our automatic stack trace mechanism on crashes, the
742 main process did not wait for the stack trace process to finish
743 its output
744 - fixed some minor memory leaks
745 - reenabled assembly features support, at the moment only for
746 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
747 - minor assembly fix in x86 features detection (don't use the PIC
748 register, to avoid relocations in the text segment at runtime)
749 - POSIX callback functions of Thread.h are hidden
750
751 * MIDI driver:
752 - dispatch bank select (MSB and LSB) messages
753
754 * audio driver:
755 - the ALSA audio output driver parameters now reflect the correct
756 parameter value ranges for the respective selected sound card
757 (patch by Till Wimmer, a bit fixed and extended)
758
759 * Gigasampler format engine:
760 - if a filter is used and EG2 finishes before EG1, let the voice
761 die when EG2 has finished (this fixes a problem with clicks and
762 voice starvation for some gigs)
763 - playback is no longer disabled during instrument loading
764 - all notes playing on a channel that changes its instrument keep
765 playing with the old instrument until they get a note off
766 command
767 - EG fix: a release value of zero could cause noises or crash
768 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
769 - EG fine tuning: when attack is zero the EG starts at a level
770 above max sustain level, which means that there is a decay phase
771 even if sustain is 100%
772 - more EG fixes: the level could sometimes go below zero and cause
773 noises or crashes
774 - minor fix of EGDecay (patch by Toshi Nagata)
775 - fixed compiler error when --enable-override-filter-type was
776 supplied to the configure script (fixes #46)
777 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
778 instead of a fix value
779 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
780 127 (solo mode) only kill voices if the respective mode really
781 changed
782
783 * LSCP server:
784 - fixed compile time error for old Bison versions
785 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
786 - parser now supports extended ASCII character set
787 (up to ASCII code 255, i.e. includes now umlauts and accents)
788 - filename arguments in LSCP commands now allow to use escape
789 sequences, that is directly literal as one of: \', \", \\, \n, \r,
790 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
791 code value like \xf2) (fixes bug #24)
792 - the following LSCP commands now also support escape sequences for at
793 least one of their text-based parameters (i.e. name, description):
794 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
795 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
796 "SET DB_INSTRUMENT_DIRECTORY NAME",
797 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
798 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
799 "FIND DB_INSTRUMENT_DIRECTORIES"
800 - returns verbose syntax errors (line and column where syntax error
801 occured, the unexpected character and the actually expected, possible
802 character(s), the latter only if less than 5 possibilities)
803 - made sure that LSCP syntax is not affected by gigedit locale
804 settings
805 - bugfix regarding strings parameter lists: all comma separated lists
806 of strings were treated as being one string containing commas
807 (fixes #57)
808
809 * Bug fixes:
810 - fixed crash occurring on certain LSCP scripts (Bug 39)
811 - another thread safety fix for lscp "load engine" and "set
812 channel audio output device"
813 - fixed a crash which occurs when reassigning the same engine
814 on a sampler channel with connected MIDI device
815 - fixed a crash which occurs when changing the number of ports of a MIDI
816 device connected to a sampler channel to number less then or equal
817 to the index of the port to which the sampler channel is connected.
818 - The previous bindings were not been disconnected when altering
819 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
820 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
821 - The active stream/voice count statistic was incorrect.
822 - notification events were not been sent for some sampler
823 channel changes
824 - added default min and max values to restrict the number of allowed
825 audio output channels and MIDI input ports
826 - the connection to the PCM interface is now closed when destroying
827 an audio output device
828 - files with slash in their path or filename could not be loaded
829
830 * test cases:
831 - updated and fixed (haven't been touched in a while)
832
833 Version 0.4.0 (24 November 2006)
834
835 * packaging changes:
836 - changed deprecated copyright attribute to license; added ldconfig
837 to post-(un)install steps; added devel package for liblinuxsampler;
838 to linuxsampler.spec (RPM)
839 - install necessary development header files for allowing 3rd party
840 applications to link against liblinuxsampler
841 - liblinuxsampler's API documentation can be generated with 'make docs'
842 (Doxygen required)
843 - added benchmark to automatically detect the best triangle LFO
844 implementation (currently either an integer math solution or a
845 di-harmonic approximation), automatic detection can be overriden
846 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
847 configure script argument though (mandatory for cross-compilation)
848 - do not automatically pick optimized gcc flags if the user already
849 provided some on his own (as CXXFLAGS)
850 - added compile time option to disable processing of All-Notes-Off MIDI
851 messages
852 - added compile time options to allow disabling the various audio and
853 MIDI drivers
854 - fixed automatic GCC CPU switch detection on PPC
855 (patch by Ebrahim Mayat)
856
857 * Gigasampler format engine:
858 - extensive synthesis optimization
859 (reimplementation of EGs and LFO(s), removed synthesis parameter
860 prerendering and the synthesis parameter matrix in general, splitting
861 each audio fragment into subfragments now where each subfragment uses
862 constant pitch and filter coefficients. The volume coefficient is
863 linearly interpolated inside a subfragment, unless
864 --disable-interpolate-volume is set.)
865 - fine tuning of the EG modulation parameters
866 - improved filter cutoff calculation by adding support for the
867 following gig parameters: Cutoff freq (used when no cutoff
868 controller is defined), Control invert, Minimum cutoff, Velocity
869 curve and Velocity range. The keyboard tracking now scales
870 cutoff frequency instead of resonance.
871 - added support for gig parameter Resonance.
872 - fixed bug in sysex handling (patch by Juan Linietsky)
873 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
874 which can be overridden with --enable-global-attenuation
875 - EG fixes: made the length of "attack hold" stage more
876 accurate. Release stage can now start before attack stage
877 ends. Cancel release didn't work when sustain was zero. Attack
878 time now has a minimal value to prevent clicks.
879 - fixed pitch changes larger than one octave
880 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
881 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
882 all modes can be altered via standard GM messages, that is CC5 for
883 altering portamento time, CC65 for enabling / disabling portamento
884 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
885 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
886 parameter) and crossfade
887 - added support for the "attenuation controller threshold" gig
888 parameter
889 - added smoothing of volume changes caused by control change
890 messages
891 - sample loop parameters are now taken from the DimensionRegion
892 instead of the wave chunk
893 - fixed keyswitching for v3 gigs with a number of keyswitch splits
894 not equal to a power of two
895 - reimplementation of the filter algorithm. The new filter is more
896 accurate and supports all gig filter types, including bandreject
897 and lowpass turbo.
898 - real support for 24 bit samples - samples are not truncated to
899 16 bits anymore
900 - support for aftertouch (channel pressure, not polyphonic
901 aftertouch)
902 - LFO1 behaviour fixed (dampening from max volume instead of
903 amplifying from 0)
904
905 * LSCP server:
906 - fixed application exit on broken pipe error (fixes bug #20)
907 - fixed the notification messages delay due to lack of
908 network activity (fixes bug #26)
909 - fixed parser bug which occured on space(s) within device parameters
910 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
911
912 * audio driver:
913 - added aRts audio output driver (by no means RT safe)
914
915 * MIDI driver:
916 - fixed legacy sysex code which caused dispatching of MIDI SysEx
917 messages several times instead of once
918 - API extension for MIDI drivers which already supply exact time stamps
919 for events (i.e. for offline rendering based MIDI drivers)
920 - added checks for bad MIDI data
921
922 * linuxsampler application:
923 - show available sampler engine types on startup
924
925 * general changes:
926 - support for muting sampler channels and solo mode of the same, two new
927 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
928 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
929 introduced for this, the behavior is the same like on a mixer console
930 (patch by Grigor Iliev, a bit adjusted). Also added configure option
931 --enable-process-muted-channels which can be used to enable the
932 processing of muted channels.
933 - support for sostenuto pedal
934 - support for monitoring the total number of active voices
935 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
936 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
937 - fixed some memory management errors
938 - fixed some concurrency problems that could lead to crashes when
939 LSCP commands were executed
940 - fixed crash when instrument loading failed previously on the same
941 sampler channel (fixes bug #36)
942
943 Version 0.3.3 (15 July 2005)
944
945 * packaging changes:
946 - fixed compilation with gcc 4.0
947
948 * Gigasampler format engine:
949 - LFO preprocessing was performed even though the respective LFO was
950 disabled by the instrument patch (minor efficiency fix)
951 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
952 for volume ramp downs in the same fragment (needed for current voice
953 stealing implementation) then simply inform the user with a warning
954 about possible click sounds and reduce the volume ramp down
955 appropriately instead of cancelling the audio device connection
956
957 Version 0.3.2 (24 June 2005)
958
959 * packaging changes:
960 - updated autotools build files to compile on OS X
961 (conditional compilation of CoreMIDI and MidiShare drivers)
962 - hand-crafted assembly optimization code can be disabled with
963 './configure --disable-asm' (definitely not recommended)
964 - fixed 'make dist' rule to include all necessary files
965 - require automake (>= 1.5) for 'make -f Makefile.cvs'
966 (due to 'dist-bzip2' automake option)
967
968 * Gigasampler format engine:
969 - support for the gig parameters for "release velocity response" curves
970 - fine tuning of the EGADSR envelope
971 - volume of release triggered samples now depends on note-on velocity,
972 note length and gig parameter "release trigger decay" instead of
973 note-off velocity.
974 - revised voice stealing
975 (fixes crash and endless loop caused by voice stealing)
976 - don't reset scale tuning on instrument or audio output device change
977 - handle key group conflicts right at the beginning of each fragment
978 instead of when the respective voice is actually launched
979 (fixes undefined behavior if stolen voices belonged to a key group -
980 this case was followed by a "killed voice survived" error message)
981 - fixed minor issue with null/silence samples
982 (those stole voices even though they don't need a voice at all which
983 resulted in "voice stealing didn't work out" messages)
984 - don't reset volume, pan, pitch and MIDI controller values on
985 instrument or audio output device change
986
987 * LSCP server:
988 - fixed some crashes (patch by Grigor Iliev, fixes #19)
989 - fixed LSCP event "CHANNEL_INFO" notification
990 (e.g. did not notify on volume changes or MIDI program change events)
991
992 * linuxsampler application:
993 - added command line parameters --lscp-addr and --lscp-port to override
994 default IP address and port of LSCP server
995
996 Version 0.3.1 (24 May 2005)
997
998 * initial release
