* Bumped version (1.0.0.svn54).

1 Version CVS HEAD (?)
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 - removed usage of deprecated Automake variable INCLUDES
27 - fixed building with C++11
28 - build fix: ChangeFlagRelaxed.h was missing in makefile
29 - build fix: libsndfile compiler flags were missing in some
30 makefiles
31 - fix for building with bison 3.0 (#202)
32 - Mac OS X: added temporary hack allowing to spawn gigedit as callback
33 on the process's main thread
34 - fixed build error on newer MinGW
35 - support building with older jack versions
36 - support building with spaces in vst sdk path
37 - enabled automake 'subdir-objects' option and moved external
38 source references (vst, au, asio) from makefiles to cpp files,
39 in order to get rid of warnings from automake 1.14
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 - Aftertouch: extended API to explicitly handle channel pressure and
103 polyphonic key pressure events (so far polyphonic pressure was not
104 supported at all, and channel pressure was rerouted as CC128 but not
105 used so far).
106 - Added initial support for real-time instrument scripts. The script VM
107 code is shared by all sampler engine implemementations, however only the
108 gig file format currently provides support for storing instrument scripts
109 (as LinuxSampler extension to the original GigaStudio 4 format).
111 * Gigasampler format engine:
112 - implemented the "round robin keyboard" dimension
113 - fixed round robin and random dimensions for cases when number of
114 dimension zones is not a power of two
115 - made round robin use a counter for each region instead of each
116 key
117 - bugfix: pitch LFO controller "internal+aftertouch" was broken
118 - bugfix: filter keyboard tracking was broken
119 - filter performance fix (an unnecessary copy was made of the
120 filter parameters in each sub fragment)
121 - handle special case when pan parameter in gig file has max or
122 min value
123 - Exclusive Groups: don't ever stop voices of the same note,
124 doesn't sound naturally with a drumkit
125 - fixed EG1 modulation when attack or release is zero
126 - Fixed support for 'aftertouch' attenuation controller.
127 - Fixed crash that happened with velocity split sounds under certain
128 conditions (see also previous commit on libgig).
130 * SFZ format engine:
131 - Initial implementation (not usable yet)
132 - added support for v2 multiple stage envelope generators
133 - added a fine-tuned v1 envelope generator instead of using the
134 one from the gig engine
135 - fixed memory leak and memory handling errors
136 - added support for trigger=first, trigger=legato and sw_previous
137 - allow non-numerical key values ("C#4" for example)

139 - fixed error when unloading instrument with same sample used by
140 multiple regions
141 - added some opcode aliases, like loopmode for loop_mode, to be
142 more compatible
143 - added support for trigger=release and rt_decay

418 - Show currently available auto completion while typing.
419 - Added support for browsing command history with up / down keys.
420 - Show all possible next symbols immediately right to the current command
421 line while typing (no double tab required for this feature, as it would
422 be the case in other shells).
423 - Added support for moving cursor left/right with arrow keys.
424 - Added support for built-in LSCP reference documentation, which will
425 automatically show the relevant LSCP reference section on screen as soon
426 as one specific LSCP command was detected while typing on the command
427 line.
429 * Real-time instrument scripts:

474 (i.e. return value of new script function "by_marks()").
475 - Pass/preserve polyphonic variable data from respective "note" event
476 handler to "release" event handler.
478 * Bug fixes:
479 - Fixed crash which may occur when MIDI key + transpose is out of range
480 - minor valgrind fixes
481 - fixed crash which occurred when changing an already deployed sampler
482 channel to a different engine type
483 - fixed crash when deleting a sampler channel or changing engine
484 type while an instrument load was in progress
485 - bugfix: playing a note while changing the instrument could cause
486 a crash, or give "Handing back unknown region" error messages
487 - bugfix: calling SET VOICES (which Fantasia does on start and
488 refresh) could cause instruments to be unloaded
489 - Mac OS X: fixed name collision of enum in EffectControl and
490 wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
491 - Mac OS X: fixed hanging threads
492 - Windows: disabled the previous thread fix on non-Mac systems, as
493 it caused hanging threads on Windows
494 - Fixed possible crashes due to corrupted MIDI/audio device list
495 after MIDI/audio device creation failure
496 - When creating MIDI instrument map entries with "PERSISTENT" type, the
497 instruments were uselessly precached with zero samples, however it still
498 took the full preloading time and on 1st program change the respective
499 instrument was completely reloaded again.
500 - fixed handling of rapid bank select and program change messages
501 sent to the same sampler channel (patch from the Open Octave
502 project, slightly adjusted)
503 - fixed crash when trying to create an effect instance with controls
504 which min and/or max values depend on the sample rate
505 - fixed bug #162
506 - bugfix: LADSPA_PATH was not evaluated correctly when containing
507 multiple paths (#165)
508 - thread safety fixes for the instrument loading thread
509 - bugfix: instrument loading crashed for sfz and sf2 in Ardour
510 (#176)
511 - more thread safety fixes for the instrument loading thread
512 - sfz/sf2 engine: fixed crash when using small audio fragment size
513 - Mac OS X: fixed crash when unloading plugin on 10.7 and later
514 - Mac OS X: fixed process hang when unloading 32-bit plugin (bug
515 introduced in previous fix)

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