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

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).
129 - fixed behaviour of filter LFO
131 * SFZ format engine:
132 - Initial implementation (not usable yet)
133 - added support for v2 multiple stage envelope generators
134 - added a fine-tuned v1 envelope generator instead of using the
135 one from the gig engine
136 - fixed memory leak and memory handling errors
137 - added support for trigger=first, trigger=legato and sw_previous
138 - allow non-numerical key values ("C#4" for example)
139 - "key" opcode now sets pitch_keycenter too
140 - fixed error when unloading instrument with same sample used by
141 multiple regions
142 - added some opcode aliases, like loopmode for loop_mode, to be
143 more compatible
144 - added support for trigger=release and rt_decay

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

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

339 - VST: implemented retrieval and switching of programs using the
340 sampler's internal MIDI instrument mapping system
342 * Instrument editor interface:

345 spawned for. This allows the instrument editors to interact more actively
346 with the sampler.
348 * MIDI driver:
349 - ALSA MIDI driver supports now "NAME" device parameter, for overriding

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

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

485 - Pass/preserve polyphonic variable data from respective "note" event
486 handler to "release" event handler.
488 * Bug fixes:
489 - Fixed crash which may occur when MIDI key + transpose is out of range

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

522 - sfz/sf2 engine: fixed crash when using small audio fragment size
523 - Mac OS X: fixed crash when unloading plugin on 10.7 and later
524 - Mac OS X: fixed process hang when unloading 32-bit plugin (bug
525 introduced in previous fix)

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