49
50 * general changes:
51 - Refactoring: moved the independent code from
52 the Gigasampler format engine to base classes
53 - command line option '--profile' is currently disabled, since the
54 respective profiling code is currently broken
55 - Introduced support for optional environment variable
56 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
57 where the sampler shall look for instrument editor plugins
58 (patch by Luis Garrido, slightly modified).
59 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
60 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
61 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
62 note (in this implementation of the sampler its simply hard routed to
63 the 1st effect send of the sampler channel, no matter what the actual
64 effect type is)
65 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
66 note (in this implementation of the sampler its simply hard routed to
67 the 2nd effect send of the sampler channel, no matter what the actual
68 effect type is)
69 - implemented support for internal LADSPA effects
70 - raised limit of program change queue from 100 to 512
71 (as suggested by Alex Stone)
72 - implemented sine LFO, pulse LFO and saw LFO
73 - experimental support for per voice equalization
74 - added command line option --exec-after-init
75 - Introduced new C++ API method:
76 EngineChannel::InstrumentFileName(int index)
77 allowing to retrieve the whole list of files used for the loaded
78 instrument on an engine channel (a.k.a. part). Some GigaStudio
79 instruments for example are splitted over several files like
80 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
81 - Added new C++ API method Sampler::GetGlobalMaxVoices().
82 - Added new C++ API method Sampler::GetGlobalMaxStreams().
83 - Added new C++ API method Sampler::SetGlobalMaxVoices().
84 - Added new C++ API method Sampler::SetGlobalMaxStreams().
85 - Various "const" and "restrict" optimizations.
86 - all engines: add pan CC value to instrument pan parameter before
87 applying panning, instead of using two separate pan functions in
88 series (#182)
89 - added a lock guard class for exception safe mutex handling and
90 used it everywhere appropriate
91 - Immediately apply scale tuning changes to active voices.
92 - Exposed scale tuning to C++ API (along to the already existing standard
93 SysEx way).
94 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
95 and broken for ppc64. (Seq_cst loads and stores are actually not
96 used in LS, so the bug wasn't noticable.)
97 - lsatomic.h: added ARMv7 support
98 - Added support for multiple MIDI input ports per sampler channel (and
99 added various new C++ methods for this new feature / design change, old
100 C++ API methods for managing SamplerChannel's MIDI inputs are now marked
101 as deprecated but are still there and should provide full behavior
102 backward compatibility).
103 - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
104 unsafe and caused compilation error with clang 2.x).
105 - Bugfix: only process the latest MIDI program change event.
106 - Introducing the LSCP shell, which provides convenient control of the
107 sampler from the command line by providing LSCP aware features.
108 - VirtualMidiDevice: Added support for program change.
109 - VirtualMidiDevice: Added support for bank select (MSB & LSB).
110 - VirtualMidiDevice: Added support for pitch bend.
111 - Aftertouch: extended API to explicitly handle channel pressure and
112 polyphonic key pressure events (so far polyphonic pressure was not
113 supported at all, and channel pressure was rerouted as CC128 but not
114 used so far).
115 - Added initial support for real-time instrument scripts. The script VM
116 code is shared by all sampler engine implemementations, however only the
117 gig file format currently provides support for storing instrument scripts
118 (as LinuxSampler extension to the original GigaStudio 4 format).
119
120 * Gigasampler format engine:
121 - implemented the "round robin keyboard" dimension
122 - fixed round robin and random dimensions for cases when number of
123 dimension zones is not a power of two
124 - made round robin use a counter for each region instead of each
125 key
126 - bugfix: pitch LFO controller "internal+aftertouch" was broken
127 - bugfix: filter keyboard tracking was broken
128 - filter performance fix (an unnecessary copy was made of the
129 filter parameters in each sub fragment)
130 - handle special case when pan parameter in gig file has max or
131 min value
132 - Exclusive Groups: don't ever stop voices of the same note,
133 doesn't sound naturally with a drumkit
134 - fixed EG1 modulation when attack or release is zero
135 - Fixed support for 'aftertouch' attenuation controller.
136 - Fixed crash that happened with velocity split sounds under certain
137 conditions (see also previous commit on libgig).
138 - fixed behaviour of filter LFO
139
140 * SFZ format engine:

304
305 * SoundFont format engine:
306 - Initial implementation (not usable yet)

317 - VST bugfix: If the host called resume() before and after
318 changing sample rate or block size, the number of channels was
319 incorrectly set to two. This caused silence in Cubase 5.
320 - save engine type (gig, sfz or sf2) in plugin state
321 - VST: when opening Fantasia, look for both 32 and 64 bit Java on
322 64 bit Windows

332 loaded a second time (this time it's for Linux and Mac, previous
333 similar fix was for Windows)
334 - thread safety fixes for the instrument loading thread
335 - LV2: use the new lv2 package if present

342 and event
343 - LV2: lv2 package 1.0 is now required to build the LV2 plugin

350
351 * Instrument editor interface:
352 - Changed instrument editor plugin interface, providing additional
353 informations like the EngineChannel for which the instrument editor was
354 spawned for. This allows the instrument editors to interact more actively

356
357 * MIDI driver:
358 - ALSA MIDI driver supports now "NAME" device parameter, for overriding
359 the ALSA sequencer client name

363 - MME: removed compiler warning
364 - CoreMIDI: implemented driver specific port parameter "CORE_MIDI_BINDINGS",
365 which allows to retrieve the list of CoreMIDI clients / ports and to connect
366 to them a la JACK, via the usual sampler APIs
367 - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
368 the driver will automatically connect to other CoreMIDI clients' ports
369 (e.g. external MIDI devices being attached to the Mac)
370 - added support for MIDI note on velocity filter
371 - CoreMIDI: fixed memory deallocation error
372 - Fixed variable underflow in VirtualMidiDevice, which caused graphical
373 virtual keyboards in frontends / instrument editors being stuck.
374 - Bugfix in VirtualMidiDevice: process note on with velocity 0 as note off.
375 - Implemented missing handling of MIDI "running status".
376 - CoreMIDI fix: a MIDIPacket can contain more than one event per packet.
377 - MME bugfix: driver wasn't closed properly
378 - CoreMIDI: automatically connect to all input sources by default (driver
379 parameter "AUTO_BIND").

441 be the case in other shells).
442 - Added support for moving cursor left/right with arrow keys.
443 - Added support for built-in LSCP reference documentation, which will
444 automatically show the relevant LSCP reference section on screen as soon

496
497 * Bug fixes:
498 - Fixed crash which may occur when MIDI key + transpose is out of range
499 - minor valgrind fixes
500 - fixed crash which occurred when changing an already deployed sampler
501 channel to a different engine type
502 - fixed crash when deleting a sampler channel or changing engine
503 type while an instrument load was in progress
504 - bugfix: playing a note while changing the instrument could cause
505 a crash, or give "Handing back unknown region" error messages
506 - bugfix: calling SET VOICES (which Fantasia does on start and
507 refresh) could cause instruments to be unloaded
508 - Mac OS X: fixed name collision of enum in EffectControl and
509 wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
510 - Mac OS X: fixed hanging threads
511 - Windows: disabled the previous thread fix on non-Mac systems, as
512 it caused hanging threads on Windows
513 - Fixed possible crashes due to corrupted MIDI/audio device list
514 after MIDI/audio device creation failure
515 - When creating MIDI instrument map entries with "PERSISTENT" type, the
516 instruments were uselessly precached with zero samples, however it still
517 took the full preloading time and on 1st program change the respective
518 instrument was completely reloaded again.
519 - fixed handling of rapid bank select and program change messages
520 sent to the same sampler channel (patch from the Open Octave
521 project, slightly adjusted)
522 - fixed crash when trying to create an effect instance with controls
523 which min and/or max values depend on the sample rate
524 - fixed bug #162

536 playing a note in a key group
537 - fixed erroneous error message piping in VoiceBase.h
538 (labelled "Disk stream not available in time")
539 - Update effects on sample rate & period size changes (to avoid
540 crashes and noise on such transitions).
541 - ignore missing LADSPA paths without ignoring valid LADSPA paths
542 (fixes #208)
543 - Fixed bug in LSCP grammar definition which caused a statement like
544 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
545 practically irrelevant, however it caused problems with the new LSCP
546 shell's auto completion feature).
547 - Fixed MIDI program change messages being ignored if quickly executed
548 after each other (fixes #231).
549
550 Version 1.0.0 (31 July 2009)
551
552 * packaging changes:
553 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
554 causing e.g. the libgig test to fail when
555 "./configure --disable-jack-driver" was used
556 (patch by Alexis Ballier)
557 - fixed compilation with gcc 4.3
558 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
559 - fixed configure so it detects x86_64 (#107)
560 - fixes for building with newer MinGW versions
561 - fix for building with bison 2.4 (#111)
562 - fixed building with libgig installed in a non-standard directory
563 - minor fix in configure for mmsystem.h detection on MinGW
564 - Windows: look for editor plugins and Fantasia using base
565 directory of liblinuxsampler dll (look in the same directory and one
566 directory above)
567 - configure script fix: removed unconditional use of SSE
568 - fixed building with sqlite installed in a non-standard directory
569 - when cross-compiling, don't try to create instruments.db
570 - fix for new mingw-w64 version, which has usleep
571
572 * general changes:
573 - bugfix: on some POSIX systems instrument editor plugins refused to
574 load as we used a non-portable Linux specific struct field
575 (fixes bug #70, patch by Ronald Baljeu)
576 - fixed endless loop which occured when loading an instrument editor
577 plugin DLL on Windows systems failed
578 - fixed memory leaks that occurred when liblinuxsampler was unloaded
579 - optimized the SynchronizedConfig class so it doesn't wait
580 unnecessarily long after an update
581 - added support for notifying instrument editors on note-on / note-off
582 events (e.g. to highlight the pressed keys on the virtual keyboard
583 of gigedit)
584 - added support for triggering notes by instrument editors (see above)
585 - be verbose on DLL load errors (on Linux)
586 - fixed di-harmonic triangle LFO implementation (this LFO implementation
587 is only used by very few systems, most pick the int math
588 implementation, which is usually faster)
589 - fixes for audio drivers with varying buffer sizes
590 - experimental support for running LinuxSampler as a DSSI, LV2 and
591 VST plugin
592 - notification events for stream/voice count statistics are now sent
593 only when there are actual changes
594 - added memory ordering constraints to improve stability on
595 multi-core and multi-cpu systems
596 - maximum voices and disk streams can now be altered at runtime
597 - fixed CPU feature detection on x86_64 (maybe fixes #108)
598 - automatic stacktrace mechanism is now turned off by default and can
599 be switched on by command line option "--stacktrace" (the automatic
600 stacktrace mechanism seems to be broken on most systems at the moment)
601 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
602 a pointer to the launched InstrumentEditor object
603 - added optional 3rd party user data parameter for following
604 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
605 InstrumentEditor::Launch(),
606 InstrumentManager::LaunchInstrumentEditor()
607 - theoretical fix: made SynchronizedConfig follow C++0x memory
608 model more strictly
609 - fixes for using large audio device buffers
610 - Windows: add the installation directory to the DLL search path
611 when loading an editor plugin (solves problems with VST and
612 gigedit on systems with other GTK versions installed)
613 - updated linuxsampler man page
614
615 * audio driver:
616 - removed the nonsense audio channel constraint (which was hard coded to
617 max. 100 audio channels) for most audio drivers
618 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
619 opposed to the LSCP specs
620 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
621 reflected the wrong value
622 - fixed a memory management bug in ASIO driver
623 - Makefile fix: JACK_CFLAGS wasn't used
624 - JACK: use jack_client_open instead of the deprecated
625 jack_client_new
626 - added (experimental) CoreAudio driver
627 - applied old fixes to the ASIO driver that were included in the
628 previous binary release but accidentally never committed to CVS
629 (fixes #117)
630 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
631 win64)
632 - VST: added support for sample rate and buffer size changes
633 - VST: close editor (Fantasia) when the VST is removed
634 - VST: avoid opening Fantasia more than once for each VST instance
635 - VST: export main function as "main" on Linux too (fix for
636 energyXT)
637 - VST: changed number of output channels from one stereo to 16
638 stereo
639 - added channel routing, fxsends and midi maps to the settings
640 stored in the plugin state
641 - performance optimization of AudioChannel::MixTo() and
642 AudioChannel::CopyTo() methods using GCC vector exensions
643 (if available)
644 - ASIO fixes: avoid initializing the device twice, avoid throwing
645 exception when getting parameters from a disconnected device
646
647 * MIDI driver:
648 - added JACK MIDI driver
649 - dispatch bank select as ordinary CC as well, the user might seriously
650 want to (mis)use it for some purpose ("fixed" in all current MIDI
651 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
652 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
653 CoreMidi or AU
654 - fixed mingw-w64 compilation error in MME driver
655 - made program change handling in MIDI thread real-time safe by
656 moving the logic to a non-RT thread
657 - fixed minor memory leak in ALSA driver
658
659 * instruments database:
660 - avoid time consuming samples scanning when adding instruments
661 to the instruments database
662 - added support for handling lost files in the instruments database
663 - Implemented option for adding instruments in separate directories
664 in the instruments database
665 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
666 - work-around for missing fnmatch function on Windows to make
667 instrument database compilable
668 - added instrument database support on Windows
669 works with both standalone mode and VST plugin.
670 the instruments DB file is located in
671 %USERPROFILE%\.linuxsampler\instruments.db which allows different
672 databases for each windows user
673 if no DB is present it automatically creates the .linuxsampler subdir
674 and then creates an empty DB
675 - fixed recursive import, which was broken on Windows
676
677 * Gigasampler format engine:
678 - fixed a memory leak that could happen when a channel was deleted
679 while notes were playing
680 - made it possible to load an instrument even if the audio thread
681 isn't running
682 - added partial support for the "Controller Triggered" MIDI rule,
683 enough for piano gigs with pedal noise samples
684 - minor fix: only mark FX sends as being modified if really the
685 respective FX send MIDI controller was used
686 - added support for GM global device volume SysEx message
687 (can be selected at compile time to either apply globally to the
688 whole sampler [default] or only to the sampler channels that are
689 connected to the respective MIDI input port the SysEx message arrived
690 on)
691 - bugfix: notes triggered at position 0 in the audio buffer were
692 sometimes wrongly killed in the same buffer, causing no sound to
693 be played
694 - added support for chromatic / drumkit mode Roland GS Sysex message
695 which is usally used to switch a part between chromatic sounds and
696 drumkit sounds (as opposed to their common default setting of MIDI
697 part 10 being a drumkit part and all other ones chromatic parts), in
698 LS however one can switch between the first 16 MIDI instrument maps
699 defined for the sampler
700 - made it possible to create multiple sample channels even if the
701 audio thread isn't running
702 - fixed crash when removing channel with active voices (#116)
703 - bugfix: on sample reference changes (instrument editor), only
704 un-cache the respective sample if it's really not used by any
705 sampler engine anymore
706 - re-cache samples in case they were changed by an instrument editor,
707 e.g. when a sample was added while playing (#82)
708 - fixed hanging notes which occured when note-off event had the exact
709 same time stamp as the voice's note-on event and occured both in the
710 same audio fragment cycle (fixes bug #112)
711 - added support for the "fine tune" and "pitch bend range"
712 instrument-level gig parameters
713 - fixed minor artifacts in pitch bend handling
714 - added support for GS Reset SysEx message
715 - allow gig files to use unlimited downward pitch shifting
716 - added a limit check for upward pitch shifting
717 - bugfix: sometimes, when playing a note twice fast, the second
718 note was silent
719 - fixed crash happening when a pitch bend event arrived at the
720 same time a new instrument was loading
721
722 * LSCP server:
723 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
724 react on MIDI data arriving on certain sampler channels (so far only
725 Note-On and Note-Off events are sent via this LSCP event)
726 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
727 react on MIDI data arriving on certain MIDI input devices (so far only
728 Note-On and Note-Off events are sent via this LSCP event)
729 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
730 SET DB_INSTRUMENT FILE_PATH
731 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
732 frontends to send MIDI messages to specific sampler channel
733 - added two additional fields to GET FILE INSTRUMENT INFO command -
734 KEY_BINDINGS and KEYSWITCH_BINDINGS
735 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
736 was incorrect
737 - Optimized the retrieval of the MIDI instrument mappings
738 - added new LSCP command "SET VOICES" to globally alter the maximum
739 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
740 be triggered respectively
741 - added new LSCP command "SET STREAMS" to globally alter the maximum
742 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
743 which will be triggered respectively
744 - bugfix: retry if "select" returns EINTR (this fixes a crash when
745 a gigedit file dialog is opened)
746 - close all connections when LSCPServer is deleted
747 - hard close of all sockets on exit
748 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
749 driver
750
751 * Bug fixes:
752 - fixed a crash which occurs when removing a sampler channel waiting
753 to start instrument loading after another channel
754 - fixed a crash which occurs when removing a sampler channel with
755 instrument loading in progress (bug #113)
756 - fixed termination caused by uncaught exception when adding MIDI
757 instrument with PERSISTENT load mode
758 - fixed possible iterator invalidations when resetting the sampler
759 - fixed memory leaks when issuing the following LSCP commands:
760 GET AUDIO_OUTPUT_DRIVER INFO
761 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
762 GET MIDI_INPUT_DRIVER INFO
763 GET MIDI_INPUT_DRIVER_PARAMETER INFO
764 - fixed possible compilation error when sqlite is not present
765 - fixed orphaned pointers when setting maximum voices limit (bug #118)
766 - fixed crash when changing the audio output device of a sampler
767 channel with loaded instrument and start playing notes
768 - fixed endless loop in Engine::SuspendAll() (bug #120)
769 - fixed a low-level atomic load function that was broken on 64-bit
770 PowerPC, which probably could cause crashes on that platform
771 - fixed a memory management error which could cause a crash when a
772 plugin was unloaded
773 - bugfix: two private structs had the same name, which could cause
774 problems if the linker chose the wrong constructor
775 - fixed low-level ConditionServer usage bug that caused lockups on
776 Windows
777
778
779 Version 0.5.1 (6 December 2007)
780
781 * packaging changes:
782 - added autoconf checks for pthread library
783 - added autoconf check for pthread bug found on certain NPTL-enabled
784 glibc versions (see Gentoo bug report #194076)
785 - added autoconf checks for MS Windows
786
787 * general changes:
788 - bugfix: the thread used by an editor plugin didn't die when the
789 editor closed
790 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
791 out all the space. operator--() did not apply size_mask after
792 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
793 order to avoid problems with the _NonVolatileReader functions.
794 - bugfix: Stream.h: added a missing divide by BytesPerSample in
795 GetWriteSpace(). Since this function is currently only used in
796 the stream's qsort() compare function, it didn't trigger any
797 bugs.
798 - Resampler.h, Synthesizer.h: cubic interpolation now works in
799 24bit mode too. Faster method to read 24bit words on little
800 endian machines (x86): replaced 3 byte reads + shifts with a 1
801 unaligned 32bit read and shift
802 - experimental support for MS Windows (MIDI input via MME, AUDIO
803 output via ASIO)
804 - made handling of SIGINT signal (Ctrl-C) a bit more robust
805 - support for monitoring the total number of active disk streams
806 (new LSCP commands: GET TOTAL_STREAM_COUNT,
807 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
808
809 * AUDIO driver:
810 - added Windows ASIO low latency audio driver
811
812 * MIDI driver:
813 - added MME Windows MIDI driver
814
815 * LSCP server:
816 - added support for Windows style path / filenames, however with
817 forward slash path separators instead of backslash
818 (i.e. "C:/foo/bar.gig")
819 - allow naughty liblscp to send non-string device parameters within
820 apostrophes as well
821 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
822 "LIST FILE INSTRUMENTS <file>" and
823 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
824 about an arbitrary instrument file on the system where the sampler is
825 running on
826
827 Version 0.5.0 (15 October 2007)
828
829 * packaging changes:
830 - config.h is not going to be installed along with liblinuxsampler's
831 API header files anymore
832 - only the API relevant header (and source) files will be exported to
833 the Doxygen API documentation (explicitly listed in Doxyfile.in)
834 - added completely new XCode project files for Mac OSX which is now
835 capable to execute our autoconf environment, thus no need anymore
836 to maintain the compile time configuration file (osx/version.h) for
837 OSX manually (patch by Toshi Nagata)
838 - fixed buggy boolean --enable-foo / --disable-foo configure script
839 parameters
840 - global.h now only covers global definitions that are needed for the
841 C++ API header files, all implementation internal global definitions
842 are now in global_private.h
843 - atomic.h is not exposed to the C++ API anymore
844 - no need to include config.h anymore for using LS's API header files
845 - fixed warnings in API doc generation
846
847 * general changes:
848 - replaced the old, confusing MIDI program change mechanism by a
849 flexible MIDI instrument mapper which allows to map arbitrary
850 (MIDI bank, MIDI program) pairs with arbitrary
851 (engine type, instrument file, file index) triplets which will be
852 loaded on the respective channel when such MIDI program change
853 messages arrive, beside that, each entry allows to define a life-time
854 strategy for the instrument, so the user can define whether the
855 instrument should i.e. be permanently loaded (to be able to switch
856 quickly among sounds) or i.e. loaded just on demand when the
857 respective program change arrives (to safe RAM space), as well as a
858 global volume factor for each entry, so the user can adjust the volume
859 dynamic of his mapped instrument collection without having to modify
860 the instrument files, also one can manage arbitrary amount of such
861 MIDI instrument maps and assign each sampler channel individually
862 a certain map, so that i.e. separation of normal instruments and
863 drumkits is possible
864 - new notification events for tracking changes to audio/MIDI devices,
865 MIDI instrument maps, MIDI instruments, FX sends, global volume.
866 - sampler was limited to load max. 200 instruments in the background
867 due to a constant size RingBuffer FIFO which is now replaced by a
868 dynamic (unlimited) size std::list FIFO
869 - added FX sends, these allow to route audio signals to arbitrary audio
870 output channels for being processed by external effect processors
871 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
872 controllers
873 - global (sampler wide) volume can now be controlled at runtime
874 - Implemented new, improved notification system
875 - fixed compilation errors regarding OSX
876 (patch by Toshi Nagata)
877 - implemented instruments database
878 - added support for escape sequences to the instruments database
879 - added highly experimental support for on-the-fly instrument editing
880 within the sampler's process (by using instrument editor plugins),
881 you'll notice the new "Registered instrument editors:" message on
882 startup, added a new LSCP command:
883 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
884 to spawn a matching instrument editor for the instrument on the
885 given sampler channel, the plugin path can be overridden at compile
886 time with ./configure --enable-plugin-dir=/some/dir
887 - added experimental code for synchronizing instrument editors hosted
888 in the sampler's process to safely edit instruments while playing
889 without a crash (hopefully) by either suspending single regions
890 wherever possible or if unavoidable whole engine(s)
891 - fixed several issues in fundamental "Thread" class: set scheduling
892 policy and priority on thread level, set a minimum stack size for
893 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
894 threads simply inherited properties of starting thread instead of
895 setting their own policy and priority
896 - minor fix in our automatic stack trace mechanism on crashes, the
897 main process did not wait for the stack trace process to finish
898 its output
899 - fixed some minor memory leaks
900 - reenabled assembly features support, at the moment only for
901 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
902 - minor assembly fix in x86 features detection (don't use the PIC
903 register, to avoid relocations in the text segment at runtime)
904 - POSIX callback functions of Thread.h are hidden
905
906 * MIDI driver:
907 - dispatch bank select (MSB and LSB) messages
908
909 * audio driver:
910 - the ALSA audio output driver parameters now reflect the correct
911 parameter value ranges for the respective selected sound card
912 (patch by Till Wimmer, a bit fixed and extended)
913
914 * Gigasampler format engine:
915 - if a filter is used and EG2 finishes before EG1, let the voice
916 die when EG2 has finished (this fixes a problem with clicks and
917 voice starvation for some gigs)
918 - playback is no longer disabled during instrument loading
919 - all notes playing on a channel that changes its instrument keep
920 playing with the old instrument until they get a note off
921 command
922 - EG fix: a release value of zero could cause noises or crash
923 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
924 - EG fine tuning: when attack is zero the EG starts at a level
925 above max sustain level, which means that there is a decay phase
926 even if sustain is 100%
927 - more EG fixes: the level could sometimes go below zero and cause
928 noises or crashes
929 - minor fix of EGDecay (patch by Toshi Nagata)
930 - fixed compiler error when --enable-override-filter-type was
931 supplied to the configure script (fixes #46)
932 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
933 instead of a fix value
934 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
935 127 (solo mode) only kill voices if the respective mode really
936 changed
937
938 * LSCP server:
939 - fixed compile time error for old Bison versions
940 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
941 - parser now supports extended ASCII character set
942 (up to ASCII code 255, i.e. includes now umlauts and accents)
943 - filename arguments in LSCP commands now allow to use escape
944 sequences, that is directly literal as one of: \', \", \\, \n, \r,
945 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
946 code value like \xf2) (fixes bug #24)
947 - the following LSCP commands now also support escape sequences for at
948 least one of their text-based parameters (i.e. name, description):
949 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
950 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
951 "SET DB_INSTRUMENT_DIRECTORY NAME",
952 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
953 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
954 "FIND DB_INSTRUMENT_DIRECTORIES"
955 - returns verbose syntax errors (line and column where syntax error
956 occured, the unexpected character and the actually expected, possible
957 character(s), the latter only if less than 5 possibilities)
958 - made sure that LSCP syntax is not affected by gigedit locale
959 settings
960 - bugfix regarding strings parameter lists: all comma separated lists
961 of strings were treated as being one string containing commas
962 (fixes #57)
963
964 * Bug fixes:
965 - fixed crash occurring on certain LSCP scripts (Bug 39)
966 - another thread safety fix for lscp "load engine" and "set
967 channel audio output device"
968 - fixed a crash which occurs when reassigning the same engine
969 on a sampler channel with connected MIDI device
970 - fixed a crash which occurs when changing the number of ports of a MIDI
971 device connected to a sampler channel to number less then or equal
972 to the index of the port to which the sampler channel is connected.
973 - The previous bindings were not been disconnected when altering
974 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
975 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
976 - The active stream/voice count statistic was incorrect.
977 - notification events were not been sent for some sampler
978 channel changes
979 - added default min and max values to restrict the number of allowed
980 audio output channels and MIDI input ports
981 - the connection to the PCM interface is now closed when destroying
982 an audio output device
983 - files with slash in their path or filename could not be loaded
984
985 * test cases:
986 - updated and fixed (haven't been touched in a while)
987
988 Version 0.4.0 (24 November 2006)
989
990 * packaging changes:
991 - changed deprecated copyright attribute to license; added ldconfig
992 to post-(un)install steps; added devel package for liblinuxsampler;
993 to linuxsampler.spec (RPM)
994 - install necessary development header files for allowing 3rd party
995 applications to link against liblinuxsampler
996 - liblinuxsampler's API documentation can be generated with 'make docs'
997 (Doxygen required)
998 - added benchmark to automatically detect the best triangle LFO
999 implementation (currently either an integer math solution or a
1000 di-harmonic approximation), automatic detection can be overriden
1001 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1002 configure script argument though (mandatory for cross-compilation)
1003 - do not automatically pick optimized gcc flags if the user already
1004 provided some on his own (as CXXFLAGS)
1005 - added compile time option to disable processing of All-Notes-Off MIDI
1006 messages
1007 - added compile time options to allow disabling the various audio and
1008 MIDI drivers
1009 - fixed automatic GCC CPU switch detection on PPC
1010 (patch by Ebrahim Mayat)
1011
1012 * Gigasampler format engine:
1013 - extensive synthesis optimization
1014 (reimplementation of EGs and LFO(s), removed synthesis parameter
1015 prerendering and the synthesis parameter matrix in general, splitting
1016 each audio fragment into subfragments now where each subfragment uses
1017 constant pitch and filter coefficients. The volume coefficient is
1018 linearly interpolated inside a subfragment, unless
1019 --disable-interpolate-volume is set.)
1020 - fine tuning of the EG modulation parameters
1021 - improved filter cutoff calculation by adding support for the
1022 following gig parameters: Cutoff freq (used when no cutoff
1023 controller is defined), Control invert, Minimum cutoff, Velocity
1024 curve and Velocity range. The keyboard tracking now scales
1025 cutoff frequency instead of resonance.
1026 - added support for gig parameter Resonance.
1027 - fixed bug in sysex handling (patch by Juan Linietsky)
1028 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1029 which can be overridden with --enable-global-attenuation
1030 - EG fixes: made the length of "attack hold" stage more
1031 accurate. Release stage can now start before attack stage
1032 ends. Cancel release didn't work when sustain was zero. Attack
1033 time now has a minimal value to prevent clicks.
1034 - fixed pitch changes larger than one octave
1035 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1036 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1037 all modes can be altered via standard GM messages, that is CC5 for
1038 altering portamento time, CC65 for enabling / disabling portamento
1039 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1040 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1041 parameter) and crossfade
1042 - added support for the "attenuation controller threshold" gig
1043 parameter
1044 - added smoothing of volume changes caused by control change
1045 messages
1046 - sample loop parameters are now taken from the DimensionRegion
1047 instead of the wave chunk
1048 - fixed keyswitching for v3 gigs with a number of keyswitch splits
1049 not equal to a power of two
1050 - reimplementation of the filter algorithm. The new filter is more
1051 accurate and supports all gig filter types, including bandreject
1052 and lowpass turbo.
1053 - real support for 24 bit samples - samples are not truncated to
1054 16 bits anymore
1055 - support for aftertouch (channel pressure, not polyphonic
1056 aftertouch)
1057 - LFO1 behaviour fixed (dampening from max volume instead of
1058 amplifying from 0)
1059
1060 * LSCP server:
1061 - fixed application exit on broken pipe error (fixes bug #20)
1062 - fixed the notification messages delay due to lack of
1063 network activity (fixes bug #26)
1064 - fixed parser bug which occured on space(s) within device parameters
1065 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1066
1067 * audio driver:
1068 - added aRts audio output driver (by no means RT safe)
1069
1070 * MIDI driver:
1071 - fixed legacy sysex code which caused dispatching of MIDI SysEx
1072 messages several times instead of once
1073 - API extension for MIDI drivers which already supply exact time stamps
1074 for events (i.e. for offline rendering based MIDI drivers)
1075 - added checks for bad MIDI data
1076
1077 * linuxsampler application:
1078 - show available sampler engine types on startup
1079
1080 * general changes:
1081 - support for muting sampler channels and solo mode of the same, two new
1082 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1083 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1084 introduced for this, the behavior is the same like on a mixer console
1085 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1086 --enable-process-muted-channels which can be used to enable the
1087 processing of muted channels.
1088 - support for sostenuto pedal
1089 - support for monitoring the total number of active voices
1090 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1091 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1092 - fixed some memory management errors
1093 - fixed some concurrency problems that could lead to crashes when
1094 LSCP commands were executed
1095 - fixed crash when instrument loading failed previously on the same
1096 sampler channel (fixes bug #36)
1097
1098 Version 0.3.3 (15 July 2005)
1099
1100 * packaging changes:
1101 - fixed compilation with gcc 4.0
1102
1103 * Gigasampler format engine:
1104 - LFO preprocessing was performed even though the respective LFO was
1105 disabled by the instrument patch (minor efficiency fix)
1106 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1107 for volume ramp downs in the same fragment (needed for current voice
1108 stealing implementation) then simply inform the user with a warning
1109 about possible click sounds and reduce the volume ramp down
1110 appropriately instead of cancelling the audio device connection
1111
1112 Version 0.3.2 (24 June 2005)
1113
1114 * packaging changes:
1115 - updated autotools build files to compile on OS X
1116 (conditional compilation of CoreMIDI and MidiShare drivers)
1117 - hand-crafted assembly optimization code can be disabled with
1118 './configure --disable-asm' (definitely not recommended)
1119 - fixed 'make dist' rule to include all necessary files
1120 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1121 (due to 'dist-bzip2' automake option)
1122
1123 * Gigasampler format engine:
1124 - support for the gig parameters for "release velocity response" curves
1125 - fine tuning of the EGADSR envelope
1126 - volume of release triggered samples now depends on note-on velocity,
1127 note length and gig parameter "release trigger decay" instead of
1128 note-off velocity.
1129 - revised voice stealing
1130 (fixes crash and endless loop caused by voice stealing)
1131 - don't reset scale tuning on instrument or audio output device change
1132 - handle key group conflicts right at the beginning of each fragment
1133 instead of when the respective voice is actually launched
1134 (fixes undefined behavior if stolen voices belonged to a key group -
1135 this case was followed by a "killed voice survived" error message)
1136 - fixed minor issue with null/silence samples
1137 (those stole voices even though they don't need a voice at all which
1138 resulted in "voice stealing didn't work out" messages)
1139 - don't reset volume, pan, pitch and MIDI controller values on
1140 instrument or audio output device change
1141
1142 * LSCP server:
1143 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1144 - fixed LSCP event "CHANNEL_INFO" notification
1145 (e.g. did not notify on volume changes or MIDI program change events)
1146
1147 * linuxsampler application:
1148 - added command line parameters --lscp-addr and --lscp-port to override
1149 default IP address and port of LSCP server
1150
1151 Version 0.3.1 (24 May 2005)
1152
1153 * initial release
