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

22 - modernized configure script
23 - fixed linkage error when building with
24 LDFLAGS="-Wl,--no-undefined" (#190)

40
41 * general changes:
42 - Refactoring: moved the independent code from
43 the Gigasampler format engine to base classes
44 - command line option '--profile' is currently disabled, since the
45 respective profiling code is currently broken
46 - Introduced support for optional environment variable
47 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
48 where the sampler shall look for instrument editor plugins
49 (patch by Luis Garrido, slightly modified).
50 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
51 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
52 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
53 note (in this implementation of the sampler its simply hard routed to
54 the 1st effect send of the sampler channel, no matter what the actual
55 effect type is)
56 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
57 note (in this implementation of the sampler its simply hard routed to
58 the 2nd effect send of the sampler channel, no matter what the actual
59 effect type is)
60 - implemented support for internal LADSPA effects
61 - raised limit of program change queue from 100 to 512
62 (as suggested by Alex Stone)
63 - implemented sine LFO, pulse LFO and saw LFO
64 - experimental support for per voice equalization
65 - added command line option --exec-after-init
66 - Introduced new C++ API method:
67 EngineChannel::InstrumentFileName(int index)
68 allowing to retrieve the whole list of files used for the loaded
69 instrument on an engine channel (a.k.a. part). Some GigaStudio
70 instruments for example are splitted over several files like
71 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
72 - Added new C++ API method Sampler::GetGlobalMaxVoices().
73 - Added new C++ API method Sampler::GetGlobalMaxStreams().
74 - Added new C++ API method Sampler::SetGlobalMaxVoices().
75 - Added new C++ API method Sampler::SetGlobalMaxStreams().
76 - Various "const" and "restrict" optimizations.
77 - all engines: add pan CC value to instrument pan parameter before
78 applying panning, instead of using two separate pan functions in
79 series (#182)
80 - added a lock guard class for exception safe mutex handling and
81 used it everywhere appropriate
82 - Immediately apply scale tuning changes to active voices.
83 - Exposed scale tuning to C++ API (along to the already existing standard
84 SysEx way).
85 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
86 and broken for ppc64. (Seq_cst loads and stores are actually not
87 used in LS, so the bug wasn't noticable.)
88 - lsatomic.h: added ARMv7 support
89 - Added support for multiple MIDI input ports per sampler channel (and
90 added various new C++ methods for this new feature / design change, old
91 C++ API methods for managing SamplerChannel's MIDI inputs are now marked
92 as deprecated but are still there and should provide full behavior
93 backward compatibility).
94 - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
95 unsafe and caused compilation error with clang 2.x).
96 - Bugfix: only process the latest MIDI program change event.
97 - Introducing the LSCP shell, which provides convenient control of the
98 sampler from the command line by providing LSCP aware features.
99 - VirtualMidiDevice: Added support for program change.
100 - VirtualMidiDevice: Added support for bank select (MSB & LSB).
101 - VirtualMidiDevice: Added support for pitch bend.
102

106 dimension zones is not a power of two
107 - made round robin use a counter for each region instead of each
108 key
109 - bugfix: pitch LFO controller "internal+aftertouch" was broken
110 - bugfix: filter keyboard tracking was broken
111 - filter performance fix (an unnecessary copy was made of the
112 filter parameters in each sub fragment)
113 - handle special case when pan parameter in gig file has max or
114 min value
115 - Exclusive Groups: don't ever stop voices of the same note,
116 doesn't sound naturally with a drumkit
117 - fixed EG1 modulation when attack or release is zero
118
119 * SFZ format engine:

412 - bugfix: calling SET VOICES (which Fantasia does on start and
413 refresh) could cause instruments to be unloaded
414 - Mac OS X: fixed name collision of enum in EffectControl and
415 wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
416 - Mac OS X: fixed hanging threads
417 - Windows: disabled the previous thread fix on non-Mac systems, as
418 it caused hanging threads on Windows
419 - Fixed possible crashes due to corrupted MIDI/audio device list
420 after MIDI/audio device creation failure
421 - When creating MIDI instrument map entries with "PERSISTENT" type, the
422 instruments were uselessly precached with zero samples, however it still
423 took the full preloading time and on 1st program change the respective
424 instrument was completely reloaded again.
425 - fixed handling of rapid bank select and program change messages
426 sent to the same sampler channel (patch from the Open Octave
427 project, slightly adjusted)
428 - fixed crash when trying to create an effect instance with controls
429 which min and/or max values depend on the sample rate
430 - fixed bug #162
431 - bugfix: LADSPA_PATH was not evaluated correctly when containing
432 multiple paths (#165)
433 - thread safety fixes for the instrument loading thread
434 - bugfix: instrument loading crashed for sfz and sf2 in Ardour
435 (#176)
436 - more thread safety fixes for the instrument loading thread
437 - sfz/sf2 engine: fixed crash when using small audio fragment size
438 - Mac OS X: fixed crash when unloading plugin on 10.7 and later
439 - Mac OS X: fixed process hang when unloading 32-bit plugin (bug
440 introduced in previous fix)
441 - fixed crash when a channel received a program change while
442 playing a note in a key group
443 - fixed erroneous error message piping in VoiceBase.h
444 (labelled "Disk stream not available in time")
445 - Update effects on sample rate & period size changes (to avoid
446 crashes and noise on such transitions).
447 - ignore missing LADSPA paths without ignoring valid LADSPA paths
448 (fixes #208)
449
450 Version 1.0.0 (31 July 2009)
451
452 * packaging changes:
453 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
454 causing e.g. the libgig test to fail when
455 "./configure --disable-jack-driver" was used
456 (patch by Alexis Ballier)
457 - fixed compilation with gcc 4.3
458 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
459 - fixed configure so it detects x86_64 (#107)
460 - fixes for building with newer MinGW versions
461 - fix for building with bison 2.4 (#111)
462 - fixed building with libgig installed in a non-standard directory
463 - minor fix in configure for mmsystem.h detection on MinGW
464 - Windows: look for editor plugins and Fantasia using base
465 directory of liblinuxsampler dll (look in the same directory and one
466 directory above)
467 - configure script fix: removed unconditional use of SSE
468 - fixed building with sqlite installed in a non-standard directory
469 - when cross-compiling, don't try to create instruments.db
470 - fix for new mingw-w64 version, which has usleep
471
472 * general changes:
473 - bugfix: on some POSIX systems instrument editor plugins refused to
474 load as we used a non-portable Linux specific struct field
475 (fixes bug #70, patch by Ronald Baljeu)
476 - fixed endless loop which occured when loading an instrument editor
477 plugin DLL on Windows systems failed
478 - fixed memory leaks that occurred when liblinuxsampler was unloaded
479 - optimized the SynchronizedConfig class so it doesn't wait
480 unnecessarily long after an update
481 - added support for notifying instrument editors on note-on / note-off
482 events (e.g. to highlight the pressed keys on the virtual keyboard
483 of gigedit)
484 - added support for triggering notes by instrument editors (see above)
485 - be verbose on DLL load errors (on Linux)
486 - fixed di-harmonic triangle LFO implementation (this LFO implementation
487 is only used by very few systems, most pick the int math
488 implementation, which is usually faster)
489 - fixes for audio drivers with varying buffer sizes
490 - experimental support for running LinuxSampler as a DSSI, LV2 and
491 VST plugin
492 - notification events for stream/voice count statistics are now sent
493 only when there are actual changes
494 - added memory ordering constraints to improve stability on
495 multi-core and multi-cpu systems
496 - maximum voices and disk streams can now be altered at runtime
497 - fixed CPU feature detection on x86_64 (maybe fixes #108)
498 - automatic stacktrace mechanism is now turned off by default and can
499 be switched on by command line option "--stacktrace" (the automatic
500 stacktrace mechanism seems to be broken on most systems at the moment)
501 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
502 a pointer to the launched InstrumentEditor object
503 - added optional 3rd party user data parameter for following
504 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
505 InstrumentEditor::Launch(),
506 InstrumentManager::LaunchInstrumentEditor()
507 - theoretical fix: made SynchronizedConfig follow C++0x memory
508 model more strictly
509 - fixes for using large audio device buffers
510 - Windows: add the installation directory to the DLL search path
511 when loading an editor plugin (solves problems with VST and
512 gigedit on systems with other GTK versions installed)
513 - updated linuxsampler man page
514
515 * audio driver:
516 - removed the nonsense audio channel constraint (which was hard coded to
517 max. 100 audio channels) for most audio drivers
518 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
519 opposed to the LSCP specs
520 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
521 reflected the wrong value
522 - fixed a memory management bug in ASIO driver
523 - Makefile fix: JACK_CFLAGS wasn't used
524 - JACK: use jack_client_open instead of the deprecated
525 jack_client_new
526 - added (experimental) CoreAudio driver
527 - applied old fixes to the ASIO driver that were included in the
528 previous binary release but accidentally never committed to CVS
529 (fixes #117)
530 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
531 win64)
532 - VST: added support for sample rate and buffer size changes
533 - VST: close editor (Fantasia) when the VST is removed
534 - VST: avoid opening Fantasia more than once for each VST instance
535 - VST: export main function as "main" on Linux too (fix for
536 energyXT)
537 - VST: changed number of output channels from one stereo to 16
538 stereo
539 - added channel routing, fxsends and midi maps to the settings
540 stored in the plugin state
541 - performance optimization of AudioChannel::MixTo() and
542 AudioChannel::CopyTo() methods using GCC vector exensions
543 (if available)
544 - ASIO fixes: avoid initializing the device twice, avoid throwing
545 exception when getting parameters from a disconnected device
546
547 * MIDI driver:
548 - added JACK MIDI driver
549 - dispatch bank select as ordinary CC as well, the user might seriously
550 want to (mis)use it for some purpose ("fixed" in all current MIDI
551 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
552 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
553 CoreMidi or AU
554 - fixed mingw-w64 compilation error in MME driver
555 - made program change handling in MIDI thread real-time safe by
556 moving the logic to a non-RT thread
557 - fixed minor memory leak in ALSA driver
558
559 * instruments database:
560 - avoid time consuming samples scanning when adding instruments
561 to the instruments database
562 - added support for handling lost files in the instruments database
563 - Implemented option for adding instruments in separate directories
564 in the instruments database
565 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
566 - work-around for missing fnmatch function on Windows to make
567 instrument database compilable
568 - added instrument database support on Windows
569 works with both standalone mode and VST plugin.
570 the instruments DB file is located in
571 %USERPROFILE%\.linuxsampler\instruments.db which allows different
572 databases for each windows user
573 if no DB is present it automatically creates the .linuxsampler subdir
574 and then creates an empty DB
575 - fixed recursive import, which was broken on Windows
576
577 * Gigasampler format engine:
578 - fixed a memory leak that could happen when a channel was deleted
579 while notes were playing
580 - made it possible to load an instrument even if the audio thread
581 isn't running
582 - added partial support for the "Controller Triggered" MIDI rule,
583 enough for piano gigs with pedal noise samples
584 - minor fix: only mark FX sends as being modified if really the
585 respective FX send MIDI controller was used
586 - added support for GM global device volume SysEx message
587 (can be selected at compile time to either apply globally to the
588 whole sampler [default] or only to the sampler channels that are
589 connected to the respective MIDI input port the SysEx message arrived
590 on)
591 - bugfix: notes triggered at position 0 in the audio buffer were
592 sometimes wrongly killed in the same buffer, causing no sound to
593 be played
594 - added support for chromatic / drumkit mode Roland GS Sysex message
595 which is usally used to switch a part between chromatic sounds and
596 drumkit sounds (as opposed to their common default setting of MIDI
597 part 10 being a drumkit part and all other ones chromatic parts), in
598 LS however one can switch between the first 16 MIDI instrument maps
599 defined for the sampler
600 - made it possible to create multiple sample channels even if the
601 audio thread isn't running
602 - fixed crash when removing channel with active voices (#116)
603 - bugfix: on sample reference changes (instrument editor), only
604 un-cache the respective sample if it's really not used by any
605 sampler engine anymore
606 - re-cache samples in case they were changed by an instrument editor,
607 e.g. when a sample was added while playing (#82)
608 - fixed hanging notes which occured when note-off event had the exact
609 same time stamp as the voice's note-on event and occured both in the
610 same audio fragment cycle (fixes bug #112)
611 - added support for the "fine tune" and "pitch bend range"
612 instrument-level gig parameters
613 - fixed minor artifacts in pitch bend handling
614 - added support for GS Reset SysEx message
615 - allow gig files to use unlimited downward pitch shifting
616 - added a limit check for upward pitch shifting
617 - bugfix: sometimes, when playing a note twice fast, the second
618 note was silent
619 - fixed crash happening when a pitch bend event arrived at the
620 same time a new instrument was loading
621
622 * LSCP server:
623 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
624 react on MIDI data arriving on certain sampler channels (so far only
625 Note-On and Note-Off events are sent via this LSCP event)
626 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
627 react on MIDI data arriving on certain MIDI input devices (so far only
628 Note-On and Note-Off events are sent via this LSCP event)
629 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
630 SET DB_INSTRUMENT FILE_PATH
631 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
632 frontends to send MIDI messages to specific sampler channel
633 - added two additional fields to GET FILE INSTRUMENT INFO command -
634 KEY_BINDINGS and KEYSWITCH_BINDINGS
635 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
636 was incorrect
637 - Optimized the retrieval of the MIDI instrument mappings
638 - added new LSCP command "SET VOICES" to globally alter the maximum
639 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
640 be triggered respectively
641 - added new LSCP command "SET STREAMS" to globally alter the maximum
642 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
643 which will be triggered respectively
644 - bugfix: retry if "select" returns EINTR (this fixes a crash when
645 a gigedit file dialog is opened)
646 - close all connections when LSCPServer is deleted
647 - hard close of all sockets on exit
648 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
649 driver
650
651 * Bug fixes:
652 - fixed a crash which occurs when removing a sampler channel waiting
653 to start instrument loading after another channel
654 - fixed a crash which occurs when removing a sampler channel with
655 instrument loading in progress (bug #113)
656 - fixed termination caused by uncaught exception when adding MIDI
657 instrument with PERSISTENT load mode
658 - fixed possible iterator invalidations when resetting the sampler
659 - fixed memory leaks when issuing the following LSCP commands:
660 GET AUDIO_OUTPUT_DRIVER INFO
661 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
662 GET MIDI_INPUT_DRIVER INFO
663 GET MIDI_INPUT_DRIVER_PARAMETER INFO
664 - fixed possible compilation error when sqlite is not present
665 - fixed orphaned pointers when setting maximum voices limit (bug #118)
666 - fixed crash when changing the audio output device of a sampler
667 channel with loaded instrument and start playing notes
668 - fixed endless loop in Engine::SuspendAll() (bug #120)
669 - fixed a low-level atomic load function that was broken on 64-bit
670 PowerPC, which probably could cause crashes on that platform
671 - fixed a memory management error which could cause a crash when a
672 plugin was unloaded
673 - bugfix: two private structs had the same name, which could cause
674 problems if the linker chose the wrong constructor
675 - fixed low-level ConditionServer usage bug that caused lockups on
676 Windows
677
678
679 Version 0.5.1 (6 December 2007)
680
681 * packaging changes:
682 - added autoconf checks for pthread library
683 - added autoconf check for pthread bug found on certain NPTL-enabled
684 glibc versions (see Gentoo bug report #194076)
685 - added autoconf checks for MS Windows
686
687 * general changes:
688 - bugfix: the thread used by an editor plugin didn't die when the
689 editor closed
690 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
691 out all the space. operator--() did not apply size_mask after
692 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
693 order to avoid problems with the _NonVolatileReader functions.
694 - bugfix: Stream.h: added a missing divide by BytesPerSample in
695 GetWriteSpace(). Since this function is currently only used in
696 the stream's qsort() compare function, it didn't trigger any
697 bugs.
698 - Resampler.h, Synthesizer.h: cubic interpolation now works in
699 24bit mode too. Faster method to read 24bit words on little
700 endian machines (x86): replaced 3 byte reads + shifts with a 1
701 unaligned 32bit read and shift
702 - experimental support for MS Windows (MIDI input via MME, AUDIO
703 output via ASIO)
704 - made handling of SIGINT signal (Ctrl-C) a bit more robust
705 - support for monitoring the total number of active disk streams
706 (new LSCP commands: GET TOTAL_STREAM_COUNT,
707 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
708
709 * AUDIO driver:
710 - added Windows ASIO low latency audio driver
711
712 * MIDI driver:
713 - added MME Windows MIDI driver
714
715 * LSCP server:
716 - added support for Windows style path / filenames, however with
717 forward slash path separators instead of backslash
718 (i.e. "C:/foo/bar.gig")
719 - allow naughty liblscp to send non-string device parameters within
720 apostrophes as well
721 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
722 "LIST FILE INSTRUMENTS <file>" and
723 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
724 about an arbitrary instrument file on the system where the sampler is
725 running on
726
727 Version 0.5.0 (15 October 2007)
728
729 * packaging changes:
730 - config.h is not going to be installed along with liblinuxsampler's
731 API header files anymore
732 - only the API relevant header (and source) files will be exported to
733 the Doxygen API documentation (explicitly listed in Doxyfile.in)
734 - added completely new XCode project files for Mac OSX which is now
735 capable to execute our autoconf environment, thus no need anymore
736 to maintain the compile time configuration file (osx/version.h) for
737 OSX manually (patch by Toshi Nagata)
738 - fixed buggy boolean --enable-foo / --disable-foo configure script
739 parameters
740 - global.h now only covers global definitions that are needed for the
741 C++ API header files, all implementation internal global definitions
742 are now in global_private.h
743 - atomic.h is not exposed to the C++ API anymore
744 - no need to include config.h anymore for using LS's API header files
745 - fixed warnings in API doc generation
746
747 * general changes:
748 - replaced the old, confusing MIDI program change mechanism by a
749 flexible MIDI instrument mapper which allows to map arbitrary
750 (MIDI bank, MIDI program) pairs with arbitrary
751 (engine type, instrument file, file index) triplets which will be
752 loaded on the respective channel when such MIDI program change
753 messages arrive, beside that, each entry allows to define a life-time
754 strategy for the instrument, so the user can define whether the
755 instrument should i.e. be permanently loaded (to be able to switch
756 quickly among sounds) or i.e. loaded just on demand when the
757 respective program change arrives (to safe RAM space), as well as a
758 global volume factor for each entry, so the user can adjust the volume
759 dynamic of his mapped instrument collection without having to modify
760 the instrument files, also one can manage arbitrary amount of such
761 MIDI instrument maps and assign each sampler channel individually
762 a certain map, so that i.e. separation of normal instruments and
763 drumkits is possible
764 - new notification events for tracking changes to audio/MIDI devices,
765 MIDI instrument maps, MIDI instruments, FX sends, global volume.
766 - sampler was limited to load max. 200 instruments in the background
767 due to a constant size RingBuffer FIFO which is now replaced by a
768 dynamic (unlimited) size std::list FIFO
769 - added FX sends, these allow to route audio signals to arbitrary audio
770 output channels for being processed by external effect processors
771 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
772 controllers
773 - global (sampler wide) volume can now be controlled at runtime
774 - Implemented new, improved notification system
775 - fixed compilation errors regarding OSX
776 (patch by Toshi Nagata)
777 - implemented instruments database
778 - added support for escape sequences to the instruments database
779 - added highly experimental support for on-the-fly instrument editing
780 within the sampler's process (by using instrument editor plugins),
781 you'll notice the new "Registered instrument editors:" message on
782 startup, added a new LSCP command:
783 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
784 to spawn a matching instrument editor for the instrument on the
785 given sampler channel, the plugin path can be overridden at compile
786 time with ./configure --enable-plugin-dir=/some/dir
787 - added experimental code for synchronizing instrument editors hosted
788 in the sampler's process to safely edit instruments while playing
789 without a crash (hopefully) by either suspending single regions
790 wherever possible or if unavoidable whole engine(s)
791 - fixed several issues in fundamental "Thread" class: set scheduling
792 policy and priority on thread level, set a minimum stack size for
793 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
794 threads simply inherited properties of starting thread instead of
795 setting their own policy and priority
796 - minor fix in our automatic stack trace mechanism on crashes, the
797 main process did not wait for the stack trace process to finish
798 its output
799 - fixed some minor memory leaks
800 - reenabled assembly features support, at the moment only for
801 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
802 - minor assembly fix in x86 features detection (don't use the PIC
803 register, to avoid relocations in the text segment at runtime)
804 - POSIX callback functions of Thread.h are hidden
805
806 * MIDI driver:
807 - dispatch bank select (MSB and LSB) messages
808
809 * audio driver:
810 - the ALSA audio output driver parameters now reflect the correct
811 parameter value ranges for the respective selected sound card
812 (patch by Till Wimmer, a bit fixed and extended)
813
814 * Gigasampler format engine:
815 - if a filter is used and EG2 finishes before EG1, let the voice
816 die when EG2 has finished (this fixes a problem with clicks and
817 voice starvation for some gigs)
818 - playback is no longer disabled during instrument loading
819 - all notes playing on a channel that changes its instrument keep
820 playing with the old instrument until they get a note off
821 command
822 - EG fix: a release value of zero could cause noises or crash
823 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
824 - EG fine tuning: when attack is zero the EG starts at a level
825 above max sustain level, which means that there is a decay phase
826 even if sustain is 100%
827 - more EG fixes: the level could sometimes go below zero and cause
828 noises or crashes
829 - minor fix of EGDecay (patch by Toshi Nagata)
830 - fixed compiler error when --enable-override-filter-type was
831 supplied to the configure script (fixes #46)
832 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
833 instead of a fix value
834 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
835 127 (solo mode) only kill voices if the respective mode really
836 changed
837
838 * LSCP server:
839 - fixed compile time error for old Bison versions
840 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
841 - parser now supports extended ASCII character set
842 (up to ASCII code 255, i.e. includes now umlauts and accents)
843 - filename arguments in LSCP commands now allow to use escape
844 sequences, that is directly literal as one of: \', \", \\, \n, \r,
845 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
846 code value like \xf2) (fixes bug #24)
847 - the following LSCP commands now also support escape sequences for at
848 least one of their text-based parameters (i.e. name, description):
849 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
850 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
851 "SET DB_INSTRUMENT_DIRECTORY NAME",
852 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
853 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
854 "FIND DB_INSTRUMENT_DIRECTORIES"
855 - returns verbose syntax errors (line and column where syntax error
856 occured, the unexpected character and the actually expected, possible
857 character(s), the latter only if less than 5 possibilities)
858 - made sure that LSCP syntax is not affected by gigedit locale
859 settings
860 - bugfix regarding strings parameter lists: all comma separated lists
861 of strings were treated as being one string containing commas
862 (fixes #57)
863
864 * Bug fixes:
865 - fixed crash occurring on certain LSCP scripts (Bug 39)
866 - another thread safety fix for lscp "load engine" and "set
867 channel audio output device"
868 - fixed a crash which occurs when reassigning the same engine
869 on a sampler channel with connected MIDI device
870 - fixed a crash which occurs when changing the number of ports of a MIDI
871 device connected to a sampler channel to number less then or equal
872 to the index of the port to which the sampler channel is connected.
873 - The previous bindings were not been disconnected when altering
874 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
875 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
876 - The active stream/voice count statistic was incorrect.
877 - notification events were not been sent for some sampler
878 channel changes
879 - added default min and max values to restrict the number of allowed
880 audio output channels and MIDI input ports
881 - the connection to the PCM interface is now closed when destroying
882 an audio output device
883 - files with slash in their path or filename could not be loaded
884
885 * test cases:
886 - updated and fixed (haven't been touched in a while)
887
888 Version 0.4.0 (24 November 2006)
889
890 * packaging changes:
891 - changed deprecated copyright attribute to license; added ldconfig
892 to post-(un)install steps; added devel package for liblinuxsampler;
893 to linuxsampler.spec (RPM)
894 - install necessary development header files for allowing 3rd party
895 applications to link against liblinuxsampler
896 - liblinuxsampler's API documentation can be generated with 'make docs'
897 (Doxygen required)
898 - added benchmark to automatically detect the best triangle LFO
899 implementation (currently either an integer math solution or a
900 di-harmonic approximation), automatic detection can be overriden
901 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
902 configure script argument though (mandatory for cross-compilation)
903 - do not automatically pick optimized gcc flags if the user already
904 provided some on his own (as CXXFLAGS)
905 - added compile time option to disable processing of All-Notes-Off MIDI
906 messages
907 - added compile time options to allow disabling the various audio and
908 MIDI drivers
909 - fixed automatic GCC CPU switch detection on PPC
910 (patch by Ebrahim Mayat)
911
912 * Gigasampler format engine:
913 - extensive synthesis optimization
914 (reimplementation of EGs and LFO(s), removed synthesis parameter
915 prerendering and the synthesis parameter matrix in general, splitting
916 each audio fragment into subfragments now where each subfragment uses
917 constant pitch and filter coefficients. The volume coefficient is
918 linearly interpolated inside a subfragment, unless
919 --disable-interpolate-volume is set.)
920 - fine tuning of the EG modulation parameters
921 - improved filter cutoff calculation by adding support for the
922 following gig parameters: Cutoff freq (used when no cutoff
923 controller is defined), Control invert, Minimum cutoff, Velocity
924 curve and Velocity range. The keyboard tracking now scales
925 cutoff frequency instead of resonance.
926 - added support for gig parameter Resonance.
927 - fixed bug in sysex handling (patch by Juan Linietsky)
928 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
929 which can be overridden with --enable-global-attenuation
930 - EG fixes: made the length of "attack hold" stage more
931 accurate. Release stage can now start before attack stage
932 ends. Cancel release didn't work when sustain was zero. Attack
933 time now has a minimal value to prevent clicks.
934 - fixed pitch changes larger than one octave
935 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
936 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
937 all modes can be altered via standard GM messages, that is CC5 for
938 altering portamento time, CC65 for enabling / disabling portamento
939 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
940 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
941 parameter) and crossfade
942 - added support for the "attenuation controller threshold" gig
943 parameter
944 - added smoothing of volume changes caused by control change
945 messages
946 - sample loop parameters are now taken from the DimensionRegion
947 instead of the wave chunk
948 - fixed keyswitching for v3 gigs with a number of keyswitch splits
949 not equal to a power of two
950 - reimplementation of the filter algorithm. The new filter is more
951 accurate and supports all gig filter types, including bandreject
952 and lowpass turbo.
953 - real support for 24 bit samples - samples are not truncated to
954 16 bits anymore
955 - support for aftertouch (channel pressure, not polyphonic
956 aftertouch)
957 - LFO1 behaviour fixed (dampening from max volume instead of
958 amplifying from 0)
959
960 * LSCP server:
961 - fixed application exit on broken pipe error (fixes bug #20)
962 - fixed the notification messages delay due to lack of
963 network activity (fixes bug #26)
964 - fixed parser bug which occured on space(s) within device parameters
965 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
966
967 * audio driver:
968 - added aRts audio output driver (by no means RT safe)
969
970 * MIDI driver:
971 - fixed legacy sysex code which caused dispatching of MIDI SysEx
972 messages several times instead of once
973 - API extension for MIDI drivers which already supply exact time stamps
974 for events (i.e. for offline rendering based MIDI drivers)
975 - added checks for bad MIDI data
976
977 * linuxsampler application:
978 - show available sampler engine types on startup
979
980 * general changes:
981 - support for muting sampler channels and solo mode of the same, two new
982 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
983 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
984 introduced for this, the behavior is the same like on a mixer console
985 (patch by Grigor Iliev, a bit adjusted). Also added configure option
986 --enable-process-muted-channels which can be used to enable the
987 processing of muted channels.
988 - support for sostenuto pedal
989 - support for monitoring the total number of active voices
990 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
991 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
992 - fixed some memory management errors
993 - fixed some concurrency problems that could lead to crashes when
994 LSCP commands were executed
995 - fixed crash when instrument loading failed previously on the same
996 sampler channel (fixes bug #36)
997
998 Version 0.3.3 (15 July 2005)
999
1000 * packaging changes:
1001 - fixed compilation with gcc 4.0
1002
1003 * Gigasampler format engine:
1004 - LFO preprocessing was performed even though the respective LFO was
1005 disabled by the instrument patch (minor efficiency fix)
1006 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1007 for volume ramp downs in the same fragment (needed for current voice
1008 stealing implementation) then simply inform the user with a warning
1009 about possible click sounds and reduce the volume ramp down
1010 appropriately instead of cancelling the audio device connection
1011
1012 Version 0.3.2 (24 June 2005)
1013
1014 * packaging changes:
1015 - updated autotools build files to compile on OS X
1016 (conditional compilation of CoreMIDI and MidiShare drivers)
1017 - hand-crafted assembly optimization code can be disabled with
1018 './configure --disable-asm' (definitely not recommended)
1019 - fixed 'make dist' rule to include all necessary files
1020 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1021 (due to 'dist-bzip2' automake option)
1022
1023 * Gigasampler format engine:
1024 - support for the gig parameters for "release velocity response" curves
1025 - fine tuning of the EGADSR envelope
1026 - volume of release triggered samples now depends on note-on velocity,
1027 note length and gig parameter "release trigger decay" instead of
1028 note-off velocity.
1029 - revised voice stealing
1030 (fixes crash and endless loop caused by voice stealing)
1031 - don't reset scale tuning on instrument or audio output device change
1032 - handle key group conflicts right at the beginning of each fragment
1033 instead of when the respective voice is actually launched
1034 (fixes undefined behavior if stolen voices belonged to a key group -
1035 this case was followed by a "killed voice survived" error message)
1036 - fixed minor issue with null/silence samples
1037 (those stole voices even though they don't need a voice at all which
1038 resulted in "voice stealing didn't work out" messages)
1039 - don't reset volume, pan, pitch and MIDI controller values on
1040 instrument or audio output device change
1041
1042 * LSCP server:
1043 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1044 - fixed LSCP event "CHANNEL_INFO" notification
1045 (e.g. did not notify on volume changes or MIDI program change events)
1046
1047 * linuxsampler application:
1048 - added command line parameters --lscp-addr and --lscp-port to override
1049 default IP address and port of LSCP server
1050
1051 Version 0.3.1 (24 May 2005)
1052
1053 * initial release
