* Implemented built-in instrument script function "set_event_mark()".
* Implemented built-in instrument script function "delete_event_mark()".
* Implemented built-in instrument script function "by_marks()".
* Added built-in instrument script int const variables $MARK_1 to $MARK_28.
* Built-in instrument script functions "ignore_event()", "note_off()" and
  "gig_set_dim_zone()" now also accept an array of event IDs as argument
  (i.e. return value of new script function "by_marks()").
* Bumped version (1.0.0.svn53).

1 Version CVS HEAD (?)
2
3 * packaging changes:
4 - fixed building with newer MinGW-w64

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 - 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).
110
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).
129
130 * SFZ format engine:
131 - Initial implementation (not usable yet)
132 - added support for v2 multiple stage envelope generators

293
294 * SoundFont format engine:
295 - Initial implementation (not usable yet)
296 - RT-safeness: avoid malloc in audio thread

304 - AU bugfix: failed to destroy its audio/MIDI devices
305 - Listen to all interfaces on Mac OS X (INADDR_ANY)
306 - VST bugfix: If the host called resume() before and after
307 changing sample rate or block size, the number of channels was
308 incorrectly set to two. This caused silence in Cubase 5.
309 - save engine type (gig, sfz or sf2) in plugin state

326 Linux, the Fantasia jar should be placed in <prefix>/share/java)
327 - VST: fixed crashes on Linux Ardour and EnergyXT
328 - DSSI bugfix: it wasn't possible to change engine type. The MIDI
329 port and audio channel routing for DSSI plugins are now visible.
330 - LV2: use urid and atom extensions instead of deprecated uri-map
331 and event
332 - LV2: lv2 package 1.0 is now required to build the LV2 plugin

350 - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
351 the driver will automatically connect to other CoreMIDI clients' ports
352 (e.g. external MIDI devices being attached to the Mac)
353 - added support for MIDI note on velocity filter
354 - CoreMIDI: fixed memory deallocation error
355 - Fixed variable underflow in VirtualMidiDevice, which caused graphical
356 virtual keyboards in frontends / instrument editors being stuck.

358 - Implemented missing handling of MIDI "running status".
359 - CoreMIDI fix: a MIDIPacket can contain more than one event per packet.
360 - MME bugfix: driver wasn't closed properly
361 - CoreMIDI: automatically connect to all input sources by default (driver

414
415 * LSCP shell:
416 - Added support for auto correction of obvious and trivial syntax mistakes.
417 - Added support for auto completion by tab key.
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.
428

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

511 - Mac OS X: fixed crash when unloading plugin on 10.7 and later
512 - Mac OS X: fixed process hang when unloading 32-bit plugin (bug
513 introduced in previous fix)
514 - fixed crash when a channel received a program change while
515 playing a note in a key group
516 - fixed erroneous error message piping in VoiceBase.h
517 (labelled "Disk stream not available in time")
518 - Update effects on sample rate & period size changes (to avoid
519 crashes and noise on such transitions).
520 - ignore missing LADSPA paths without ignoring valid LADSPA paths
521 (fixes #208)
522 - Fixed bug in LSCP grammar definition which caused a statement like
523 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
524 practically irrelevant, however it caused problems with the new LSCP
525 shell's auto completion feature).
526
527 Version 1.0.0 (31 July 2009)
528
529 * packaging changes:
530 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
531 causing e.g. the libgig test to fail when
532 "./configure --disable-jack-driver" was used
533 (patch by Alexis Ballier)
534 - fixed compilation with gcc 4.3
535 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
536 - fixed configure so it detects x86_64 (#107)
537 - fixes for building with newer MinGW versions
538 - fix for building with bison 2.4 (#111)
539 - fixed building with libgig installed in a non-standard directory
540 - minor fix in configure for mmsystem.h detection on MinGW
541 - Windows: look for editor plugins and Fantasia using base
542 directory of liblinuxsampler dll (look in the same directory and one
543 directory above)
544 - configure script fix: removed unconditional use of SSE
545 - fixed building with sqlite installed in a non-standard directory
546 - when cross-compiling, don't try to create instruments.db
547 - fix for new mingw-w64 version, which has usleep
548
549 * general changes:
550 - bugfix: on some POSIX systems instrument editor plugins refused to
551 load as we used a non-portable Linux specific struct field
552 (fixes bug #70, patch by Ronald Baljeu)
553 - fixed endless loop which occured when loading an instrument editor
554 plugin DLL on Windows systems failed
555 - fixed memory leaks that occurred when liblinuxsampler was unloaded
556 - optimized the SynchronizedConfig class so it doesn't wait
557 unnecessarily long after an update
558 - added support for notifying instrument editors on note-on / note-off
559 events (e.g. to highlight the pressed keys on the virtual keyboard
560 of gigedit)
561 - added support for triggering notes by instrument editors (see above)
562 - be verbose on DLL load errors (on Linux)
563 - fixed di-harmonic triangle LFO implementation (this LFO implementation
564 is only used by very few systems, most pick the int math
565 implementation, which is usually faster)
566 - fixes for audio drivers with varying buffer sizes
567 - experimental support for running LinuxSampler as a DSSI, LV2 and
568 VST plugin
569 - notification events for stream/voice count statistics are now sent
570 only when there are actual changes
571 - added memory ordering constraints to improve stability on
572 multi-core and multi-cpu systems
573 - maximum voices and disk streams can now be altered at runtime
574 - fixed CPU feature detection on x86_64 (maybe fixes #108)
575 - automatic stacktrace mechanism is now turned off by default and can
576 be switched on by command line option "--stacktrace" (the automatic
577 stacktrace mechanism seems to be broken on most systems at the moment)
578 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
579 a pointer to the launched InstrumentEditor object
580 - added optional 3rd party user data parameter for following
581 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
582 InstrumentEditor::Launch(),
583 InstrumentManager::LaunchInstrumentEditor()
584 - theoretical fix: made SynchronizedConfig follow C++0x memory
585 model more strictly
586 - fixes for using large audio device buffers
587 - Windows: add the installation directory to the DLL search path
588 when loading an editor plugin (solves problems with VST and
589 gigedit on systems with other GTK versions installed)
590 - updated linuxsampler man page
591
592 * audio driver:
593 - removed the nonsense audio channel constraint (which was hard coded to
594 max. 100 audio channels) for most audio drivers
595 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
596 opposed to the LSCP specs
597 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
598 reflected the wrong value
599 - fixed a memory management bug in ASIO driver
600 - Makefile fix: JACK_CFLAGS wasn't used
601 - JACK: use jack_client_open instead of the deprecated
602 jack_client_new
603 - added (experimental) CoreAudio driver
604 - applied old fixes to the ASIO driver that were included in the
605 previous binary release but accidentally never committed to CVS
606 (fixes #117)
607 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
608 win64)
609 - VST: added support for sample rate and buffer size changes
610 - VST: close editor (Fantasia) when the VST is removed
611 - VST: avoid opening Fantasia more than once for each VST instance
612 - VST: export main function as "main" on Linux too (fix for
613 energyXT)
614 - VST: changed number of output channels from one stereo to 16
615 stereo
616 - added channel routing, fxsends and midi maps to the settings
617 stored in the plugin state
618 - performance optimization of AudioChannel::MixTo() and
619 AudioChannel::CopyTo() methods using GCC vector exensions
620 (if available)
621 - ASIO fixes: avoid initializing the device twice, avoid throwing
622 exception when getting parameters from a disconnected device
623
624 * MIDI driver:
625 - added JACK MIDI driver
626 - dispatch bank select as ordinary CC as well, the user might seriously
627 want to (mis)use it for some purpose ("fixed" in all current MIDI
628 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
629 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
630 CoreMidi or AU
631 - fixed mingw-w64 compilation error in MME driver
632 - made program change handling in MIDI thread real-time safe by
633 moving the logic to a non-RT thread
634 - fixed minor memory leak in ALSA driver
635
636 * instruments database:
637 - avoid time consuming samples scanning when adding instruments
638 to the instruments database
639 - added support for handling lost files in the instruments database
640 - Implemented option for adding instruments in separate directories
641 in the instruments database
642 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
643 - work-around for missing fnmatch function on Windows to make
644 instrument database compilable
645 - added instrument database support on Windows
646 works with both standalone mode and VST plugin.
647 the instruments DB file is located in
648 %USERPROFILE%\.linuxsampler\instruments.db which allows different
649 databases for each windows user
650 if no DB is present it automatically creates the .linuxsampler subdir
651 and then creates an empty DB
652 - fixed recursive import, which was broken on Windows
653
654 * Gigasampler format engine:
655 - fixed a memory leak that could happen when a channel was deleted
656 while notes were playing
657 - made it possible to load an instrument even if the audio thread
658 isn't running
659 - added partial support for the "Controller Triggered" MIDI rule,
660 enough for piano gigs with pedal noise samples
661 - minor fix: only mark FX sends as being modified if really the
662 respective FX send MIDI controller was used
663 - added support for GM global device volume SysEx message
664 (can be selected at compile time to either apply globally to the
665 whole sampler [default] or only to the sampler channels that are
666 connected to the respective MIDI input port the SysEx message arrived
667 on)
668 - bugfix: notes triggered at position 0 in the audio buffer were
669 sometimes wrongly killed in the same buffer, causing no sound to
670 be played
671 - added support for chromatic / drumkit mode Roland GS Sysex message
672 which is usally used to switch a part between chromatic sounds and
673 drumkit sounds (as opposed to their common default setting of MIDI
674 part 10 being a drumkit part and all other ones chromatic parts), in
675 LS however one can switch between the first 16 MIDI instrument maps
676 defined for the sampler
677 - made it possible to create multiple sample channels even if the
678 audio thread isn't running
679 - fixed crash when removing channel with active voices (#116)
680 - bugfix: on sample reference changes (instrument editor), only
681 un-cache the respective sample if it's really not used by any
682 sampler engine anymore
683 - re-cache samples in case they were changed by an instrument editor,
684 e.g. when a sample was added while playing (#82)
685 - fixed hanging notes which occured when note-off event had the exact
686 same time stamp as the voice's note-on event and occured both in the
687 same audio fragment cycle (fixes bug #112)
688 - added support for the "fine tune" and "pitch bend range"
689 instrument-level gig parameters
690 - fixed minor artifacts in pitch bend handling
691 - added support for GS Reset SysEx message
692 - allow gig files to use unlimited downward pitch shifting
693 - added a limit check for upward pitch shifting
694 - bugfix: sometimes, when playing a note twice fast, the second
695 note was silent
696 - fixed crash happening when a pitch bend event arrived at the
697 same time a new instrument was loading
698
699 * LSCP server:
700 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
701 react on MIDI data arriving on certain sampler channels (so far only
702 Note-On and Note-Off events are sent via this LSCP event)
703 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
704 react on MIDI data arriving on certain MIDI input devices (so far only
705 Note-On and Note-Off events are sent via this LSCP event)
706 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
707 SET DB_INSTRUMENT FILE_PATH
708 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
709 frontends to send MIDI messages to specific sampler channel
710 - added two additional fields to GET FILE INSTRUMENT INFO command -
711 KEY_BINDINGS and KEYSWITCH_BINDINGS
712 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
713 was incorrect
714 - Optimized the retrieval of the MIDI instrument mappings
715 - added new LSCP command "SET VOICES" to globally alter the maximum
716 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
717 be triggered respectively
718 - added new LSCP command "SET STREAMS" to globally alter the maximum
719 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
720 which will be triggered respectively
721 - bugfix: retry if "select" returns EINTR (this fixes a crash when
722 a gigedit file dialog is opened)
723 - close all connections when LSCPServer is deleted
724 - hard close of all sockets on exit
725 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
726 driver
727
728 * Bug fixes:
729 - fixed a crash which occurs when removing a sampler channel waiting
730 to start instrument loading after another channel
731 - fixed a crash which occurs when removing a sampler channel with
732 instrument loading in progress (bug #113)
733 - fixed termination caused by uncaught exception when adding MIDI
734 instrument with PERSISTENT load mode
735 - fixed possible iterator invalidations when resetting the sampler
736 - fixed memory leaks when issuing the following LSCP commands:
737 GET AUDIO_OUTPUT_DRIVER INFO
738 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
739 GET MIDI_INPUT_DRIVER INFO
740 GET MIDI_INPUT_DRIVER_PARAMETER INFO
741 - fixed possible compilation error when sqlite is not present
742 - fixed orphaned pointers when setting maximum voices limit (bug #118)
743 - fixed crash when changing the audio output device of a sampler
744 channel with loaded instrument and start playing notes
745 - fixed endless loop in Engine::SuspendAll() (bug #120)
746 - fixed a low-level atomic load function that was broken on 64-bit
747 PowerPC, which probably could cause crashes on that platform
748 - fixed a memory management error which could cause a crash when a
749 plugin was unloaded
750 - bugfix: two private structs had the same name, which could cause
751 problems if the linker chose the wrong constructor
752 - fixed low-level ConditionServer usage bug that caused lockups on
753 Windows
754
755
756 Version 0.5.1 (6 December 2007)
757
758 * packaging changes:
759 - added autoconf checks for pthread library
760 - added autoconf check for pthread bug found on certain NPTL-enabled
761 glibc versions (see Gentoo bug report #194076)
762 - added autoconf checks for MS Windows
763
764 * general changes:
765 - bugfix: the thread used by an editor plugin didn't die when the
766 editor closed
767 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
768 out all the space. operator--() did not apply size_mask after
769 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
770 order to avoid problems with the _NonVolatileReader functions.
771 - bugfix: Stream.h: added a missing divide by BytesPerSample in
772 GetWriteSpace(). Since this function is currently only used in
773 the stream's qsort() compare function, it didn't trigger any
774 bugs.
775 - Resampler.h, Synthesizer.h: cubic interpolation now works in
776 24bit mode too. Faster method to read 24bit words on little
777 endian machines (x86): replaced 3 byte reads + shifts with a 1
778 unaligned 32bit read and shift
779 - experimental support for MS Windows (MIDI input via MME, AUDIO
780 output via ASIO)
781 - made handling of SIGINT signal (Ctrl-C) a bit more robust
782 - support for monitoring the total number of active disk streams
783 (new LSCP commands: GET TOTAL_STREAM_COUNT,
784 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
785
786 * AUDIO driver:
787 - added Windows ASIO low latency audio driver
788
789 * MIDI driver:
790 - added MME Windows MIDI driver
791
792 * LSCP server:
793 - added support for Windows style path / filenames, however with
794 forward slash path separators instead of backslash
795 (i.e. "C:/foo/bar.gig")
796 - allow naughty liblscp to send non-string device parameters within
797 apostrophes as well
798 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
799 "LIST FILE INSTRUMENTS <file>" and
800 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
801 about an arbitrary instrument file on the system where the sampler is
802 running on
803
804 Version 0.5.0 (15 October 2007)
805
806 * packaging changes:
807 - config.h is not going to be installed along with liblinuxsampler's
808 API header files anymore
809 - only the API relevant header (and source) files will be exported to
810 the Doxygen API documentation (explicitly listed in Doxyfile.in)
811 - added completely new XCode project files for Mac OSX which is now
812 capable to execute our autoconf environment, thus no need anymore
813 to maintain the compile time configuration file (osx/version.h) for
814 OSX manually (patch by Toshi Nagata)
815 - fixed buggy boolean --enable-foo / --disable-foo configure script
816 parameters
817 - global.h now only covers global definitions that are needed for the
818 C++ API header files, all implementation internal global definitions
819 are now in global_private.h
820 - atomic.h is not exposed to the C++ API anymore
821 - no need to include config.h anymore for using LS's API header files
822 - fixed warnings in API doc generation
823
824 * general changes:
825 - replaced the old, confusing MIDI program change mechanism by a
826 flexible MIDI instrument mapper which allows to map arbitrary
827 (MIDI bank, MIDI program) pairs with arbitrary
828 (engine type, instrument file, file index) triplets which will be
829 loaded on the respective channel when such MIDI program change
830 messages arrive, beside that, each entry allows to define a life-time
831 strategy for the instrument, so the user can define whether the
832 instrument should i.e. be permanently loaded (to be able to switch
833 quickly among sounds) or i.e. loaded just on demand when the
834 respective program change arrives (to safe RAM space), as well as a
835 global volume factor for each entry, so the user can adjust the volume
836 dynamic of his mapped instrument collection without having to modify
837 the instrument files, also one can manage arbitrary amount of such
838 MIDI instrument maps and assign each sampler channel individually
839 a certain map, so that i.e. separation of normal instruments and
840 drumkits is possible
841 - new notification events for tracking changes to audio/MIDI devices,
842 MIDI instrument maps, MIDI instruments, FX sends, global volume.
843 - sampler was limited to load max. 200 instruments in the background
844 due to a constant size RingBuffer FIFO which is now replaced by a
845 dynamic (unlimited) size std::list FIFO
846 - added FX sends, these allow to route audio signals to arbitrary audio
847 output channels for being processed by external effect processors
848 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
849 controllers
850 - global (sampler wide) volume can now be controlled at runtime
851 - Implemented new, improved notification system
852 - fixed compilation errors regarding OSX
853 (patch by Toshi Nagata)
854 - implemented instruments database
855 - added support for escape sequences to the instruments database
856 - added highly experimental support for on-the-fly instrument editing
857 within the sampler's process (by using instrument editor plugins),
858 you'll notice the new "Registered instrument editors:" message on
859 startup, added a new LSCP command:
860 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
861 to spawn a matching instrument editor for the instrument on the
862 given sampler channel, the plugin path can be overridden at compile
863 time with ./configure --enable-plugin-dir=/some/dir
864 - added experimental code for synchronizing instrument editors hosted
865 in the sampler's process to safely edit instruments while playing
866 without a crash (hopefully) by either suspending single regions
867 wherever possible or if unavoidable whole engine(s)
868 - fixed several issues in fundamental "Thread" class: set scheduling
869 policy and priority on thread level, set a minimum stack size for
870 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
871 threads simply inherited properties of starting thread instead of
872 setting their own policy and priority
873 - minor fix in our automatic stack trace mechanism on crashes, the
874 main process did not wait for the stack trace process to finish
875 its output
876 - fixed some minor memory leaks
877 - reenabled assembly features support, at the moment only for
878 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
879 - minor assembly fix in x86 features detection (don't use the PIC
880 register, to avoid relocations in the text segment at runtime)
881 - POSIX callback functions of Thread.h are hidden
882
883 * MIDI driver:
884 - dispatch bank select (MSB and LSB) messages
885
886 * audio driver:
887 - the ALSA audio output driver parameters now reflect the correct
888 parameter value ranges for the respective selected sound card
889 (patch by Till Wimmer, a bit fixed and extended)
890
891 * Gigasampler format engine:
892 - if a filter is used and EG2 finishes before EG1, let the voice
893 die when EG2 has finished (this fixes a problem with clicks and
894 voice starvation for some gigs)
895 - playback is no longer disabled during instrument loading
896 - all notes playing on a channel that changes its instrument keep
897 playing with the old instrument until they get a note off
898 command
899 - EG fix: a release value of zero could cause noises or crash
900 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
901 - EG fine tuning: when attack is zero the EG starts at a level
902 above max sustain level, which means that there is a decay phase
903 even if sustain is 100%
904 - more EG fixes: the level could sometimes go below zero and cause
905 noises or crashes
906 - minor fix of EGDecay (patch by Toshi Nagata)
907 - fixed compiler error when --enable-override-filter-type was
908 supplied to the configure script (fixes #46)
909 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
910 instead of a fix value
911 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
912 127 (solo mode) only kill voices if the respective mode really
913 changed
914
915 * LSCP server:
916 - fixed compile time error for old Bison versions
917 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
918 - parser now supports extended ASCII character set
919 (up to ASCII code 255, i.e. includes now umlauts and accents)
920 - filename arguments in LSCP commands now allow to use escape
921 sequences, that is directly literal as one of: \', \", \\, \n, \r,
922 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
923 code value like \xf2) (fixes bug #24)
924 - the following LSCP commands now also support escape sequences for at
925 least one of their text-based parameters (i.e. name, description):
926 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
927 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
928 "SET DB_INSTRUMENT_DIRECTORY NAME",
929 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
930 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
931 "FIND DB_INSTRUMENT_DIRECTORIES"
932 - returns verbose syntax errors (line and column where syntax error
933 occured, the unexpected character and the actually expected, possible
934 character(s), the latter only if less than 5 possibilities)
935 - made sure that LSCP syntax is not affected by gigedit locale
936 settings
937 - bugfix regarding strings parameter lists: all comma separated lists
938 of strings were treated as being one string containing commas
939 (fixes #57)
940
941 * Bug fixes:
942 - fixed crash occurring on certain LSCP scripts (Bug 39)
943 - another thread safety fix for lscp "load engine" and "set
944 channel audio output device"
945 - fixed a crash which occurs when reassigning the same engine
946 on a sampler channel with connected MIDI device
947 - fixed a crash which occurs when changing the number of ports of a MIDI
948 device connected to a sampler channel to number less then or equal
949 to the index of the port to which the sampler channel is connected.
950 - The previous bindings were not been disconnected when altering
951 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
952 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
953 - The active stream/voice count statistic was incorrect.
954 - notification events were not been sent for some sampler
955 channel changes
956 - added default min and max values to restrict the number of allowed
957 audio output channels and MIDI input ports
958 - the connection to the PCM interface is now closed when destroying
959 an audio output device
960 - files with slash in their path or filename could not be loaded
961
962 * test cases:
963 - updated and fixed (haven't been touched in a while)
964
965 Version 0.4.0 (24 November 2006)
966
967 * packaging changes:
968 - changed deprecated copyright attribute to license; added ldconfig
969 to post-(un)install steps; added devel package for liblinuxsampler;
970 to linuxsampler.spec (RPM)
971 - install necessary development header files for allowing 3rd party
972 applications to link against liblinuxsampler
973 - liblinuxsampler's API documentation can be generated with 'make docs'
974 (Doxygen required)
975 - added benchmark to automatically detect the best triangle LFO
976 implementation (currently either an integer math solution or a
977 di-harmonic approximation), automatic detection can be overriden
978 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
979 configure script argument though (mandatory for cross-compilation)
980 - do not automatically pick optimized gcc flags if the user already
981 provided some on his own (as CXXFLAGS)
982 - added compile time option to disable processing of All-Notes-Off MIDI
983 messages
984 - added compile time options to allow disabling the various audio and
985 MIDI drivers
986 - fixed automatic GCC CPU switch detection on PPC
987 (patch by Ebrahim Mayat)
988
989 * Gigasampler format engine:
990 - extensive synthesis optimization
991 (reimplementation of EGs and LFO(s), removed synthesis parameter
992 prerendering and the synthesis parameter matrix in general, splitting
993 each audio fragment into subfragments now where each subfragment uses
994 constant pitch and filter coefficients. The volume coefficient is
995 linearly interpolated inside a subfragment, unless
996 --disable-interpolate-volume is set.)
997 - fine tuning of the EG modulation parameters
998 - improved filter cutoff calculation by adding support for the
999 following gig parameters: Cutoff freq (used when no cutoff
1000 controller is defined), Control invert, Minimum cutoff, Velocity
1001 curve and Velocity range. The keyboard tracking now scales
1002 cutoff frequency instead of resonance.
1003 - added support for gig parameter Resonance.
1004 - fixed bug in sysex handling (patch by Juan Linietsky)
1005 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1006 which can be overridden with --enable-global-attenuation
1007 - EG fixes: made the length of "attack hold" stage more
1008 accurate. Release stage can now start before attack stage
1009 ends. Cancel release didn't work when sustain was zero. Attack
1010 time now has a minimal value to prevent clicks.
1011 - fixed pitch changes larger than one octave
1012 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1013 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1014 all modes can be altered via standard GM messages, that is CC5 for
1015 altering portamento time, CC65 for enabling / disabling portamento
1016 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1017 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1018 parameter) and crossfade
1019 - added support for the "attenuation controller threshold" gig
1020 parameter
1021 - added smoothing of volume changes caused by control change
1022 messages
1023 - sample loop parameters are now taken from the DimensionRegion
1024 instead of the wave chunk
1025 - fixed keyswitching for v3 gigs with a number of keyswitch splits
1026 not equal to a power of two
1027 - reimplementation of the filter algorithm. The new filter is more
1028 accurate and supports all gig filter types, including bandreject
1029 and lowpass turbo.
1030 - real support for 24 bit samples - samples are not truncated to
1031 16 bits anymore
1032 - support for aftertouch (channel pressure, not polyphonic
1033 aftertouch)
1034 - LFO1 behaviour fixed (dampening from max volume instead of
1035 amplifying from 0)
1036
1037 * LSCP server:
1038 - fixed application exit on broken pipe error (fixes bug #20)
1039 - fixed the notification messages delay due to lack of
1040 network activity (fixes bug #26)
1041 - fixed parser bug which occured on space(s) within device parameters
1042 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1043
1044 * audio driver:
1045 - added aRts audio output driver (by no means RT safe)
1046
1047 * MIDI driver:
1048 - fixed legacy sysex code which caused dispatching of MIDI SysEx
1049 messages several times instead of once
1050 - API extension for MIDI drivers which already supply exact time stamps
1051 for events (i.e. for offline rendering based MIDI drivers)
1052 - added checks for bad MIDI data
1053
1054 * linuxsampler application:
1055 - show available sampler engine types on startup
1056
1057 * general changes:
1058 - support for muting sampler channels and solo mode of the same, two new
1059 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1060 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1061 introduced for this, the behavior is the same like on a mixer console
1062 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1063 --enable-process-muted-channels which can be used to enable the
1064 processing of muted channels.
1065 - support for sostenuto pedal
1066 - support for monitoring the total number of active voices
1067 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1068 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1069 - fixed some memory management errors
1070 - fixed some concurrency problems that could lead to crashes when
1071 LSCP commands were executed
1072 - fixed crash when instrument loading failed previously on the same
1073 sampler channel (fixes bug #36)
1074
1075 Version 0.3.3 (15 July 2005)
1076
1077 * packaging changes:
1078 - fixed compilation with gcc 4.0
1079
1080 * Gigasampler format engine:
1081 - LFO preprocessing was performed even though the respective LFO was
1082 disabled by the instrument patch (minor efficiency fix)
1083 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1084 for volume ramp downs in the same fragment (needed for current voice
1085 stealing implementation) then simply inform the user with a warning
1086 about possible click sounds and reduce the volume ramp down
1087 appropriately instead of cancelling the audio device connection
1088
1089 Version 0.3.2 (24 June 2005)
1090
1091 * packaging changes:
1092 - updated autotools build files to compile on OS X
1093 (conditional compilation of CoreMIDI and MidiShare drivers)
1094 - hand-crafted assembly optimization code can be disabled with
1095 './configure --disable-asm' (definitely not recommended)
1096 - fixed 'make dist' rule to include all necessary files
1097 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1098 (due to 'dist-bzip2' automake option)
1099
1100 * Gigasampler format engine:
1101 - support for the gig parameters for "release velocity response" curves
1102 - fine tuning of the EGADSR envelope
1103 - volume of release triggered samples now depends on note-on velocity,
1104 note length and gig parameter "release trigger decay" instead of
1105 note-off velocity.
1106 - revised voice stealing
1107 (fixes crash and endless loop caused by voice stealing)
1108 - don't reset scale tuning on instrument or audio output device change
1109 - handle key group conflicts right at the beginning of each fragment
1110 instead of when the respective voice is actually launched
1111 (fixes undefined behavior if stolen voices belonged to a key group -
1112 this case was followed by a "killed voice survived" error message)
1113 - fixed minor issue with null/silence samples
1114 (those stole voices even though they don't need a voice at all which
1115 resulted in "voice stealing didn't work out" messages)
1116 - don't reset volume, pan, pitch and MIDI controller values on
1117 instrument or audio output device change
1118
1119 * LSCP server:
1120 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1121 - fixed LSCP event "CHANNEL_INFO" notification
1122 (e.g. did not notify on volume changes or MIDI program change events)
1123
1124 * linuxsampler application:
1125 - added command line parameters --lscp-addr and --lscp-port to override
1126 default IP address and port of LSCP server
1127
1128 Version 0.3.1 (24 May 2005)
1129
1130 * initial release
