* ScriptVM (WIP): started to integrate real-time instrument script
  support into the sampler engine implementations. The code is
  shared among all sampler engines, however currently only the gig
  file format supports storing instrument scripts (as LinuxSampler
  extension to the original GigaStudio 4 file format).
* gig engine: Added support for loading instrument scripts from .gig
  files.
* ScriptVM (WIP): Implemented built-in script variables %CC, $CC_NUM,
  $EVENT_NOTE, $EVENT_VELOCITY, $VCC_MONO_AT, $VCC_PITCH_BEND.
* ScriptVM (WIP): Implemented execution of script event handler "init".
* ScriptVM (WIP): Implemented execution of script event handler
  "controller".
* Bumped version (1.0.0.svn42).

1 Version CVS HEAD (?)
2
3 * packaging changes:
4 - fixed building with newer MinGW-w64
5 - Mac OS X: support the new dir for Core Audio SDK
6 - Mac OS X: fixed building outside source directory
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
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)

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

322 similar fix was for Windows)
323 - thread safety fixes for the instrument loading thread
324 - LV2: use the new lv2 package if present

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

403 <effect-chain> <effect-chain-pos> <effect-instance>"
404 - added LSCP command "REMOVE SEND_EFFECT_CHAIN EFFECT <audio-device>
405 <effect-chain> <chain-pos>"
406 - added LSCP command "SET FX_SEND EFFECT <sampler_channel>
407 <fx_send_id> <effect_chain> <chain_pos>"
408 - added LSCP command "REMOVE FX_SEND EFFECT <sampler_channel> <fx_send_id>"
409 - added LSCP commands "SUBSCRIBE EFFECT_INSTANCE_COUNT",

411 "SUBSCRIBE SEND_EFFECT_CHAIN_INFO"
412 - provide comprehensive error messages on LSCP syntax errors
413 (suggesting expected next non-terminal symbols)
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
429 * Real-time instrument scripts:
430 - Implemented built-in script array variable %CC.
431 - Implemented built-in script int variable $CC_NUM.
432 - Implemented built-in script int variable $EVENT_NOTE.
433 - Implemented built-in script int variable $EVENT_VELOCITY.

438
439 * Bug fixes:
440 - Fixed crash which may occur when MIDI key + transpose is out of range
441 - minor valgrind fixes
442 - fixed crash which occurred when changing an already deployed sampler
443 channel to a different engine type
444 - fixed crash when deleting a sampler channel or changing engine
445 type while an instrument load was in progress
446 - bugfix: playing a note while changing the instrument could cause
447 a crash, or give "Handing back unknown region" error messages
448 - bugfix: calling SET VOICES (which Fantasia does on start and
449 refresh) could cause instruments to be unloaded
450 - Mac OS X: fixed name collision of enum in EffectControl and
451 wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
452 - Mac OS X: fixed hanging threads
453 - Windows: disabled the previous thread fix on non-Mac systems, as
454 it caused hanging threads on Windows
455 - Fixed possible crashes due to corrupted MIDI/audio device list
456 after MIDI/audio device creation failure
457 - When creating MIDI instrument map entries with "PERSISTENT" type, the
458 instruments were uselessly precached with zero samples, however it still
459 took the full preloading time and on 1st program change the respective
460 instrument was completely reloaded again.
461 - fixed handling of rapid bank select and program change messages
462 sent to the same sampler channel (patch from the Open Octave
463 project, slightly adjusted)
464 - fixed crash when trying to create an effect instance with controls
465 which min and/or max values depend on the sample rate
466 - fixed bug #162
467 - bugfix: LADSPA_PATH was not evaluated correctly when containing
468 multiple paths (#165)
469 - thread safety fixes for the instrument loading thread
470 - bugfix: instrument loading crashed for sfz and sf2 in Ardour
471 (#176)
472 - more thread safety fixes for the instrument loading thread
473 - sfz/sf2 engine: fixed crash when using small audio fragment size
474 - Mac OS X: fixed crash when unloading plugin on 10.7 and later
475 - Mac OS X: fixed process hang when unloading 32-bit plugin (bug
476 introduced in previous fix)
477 - fixed crash when a channel received a program change while
478 playing a note in a key group
479 - fixed erroneous error message piping in VoiceBase.h
480 (labelled "Disk stream not available in time")
481 - Update effects on sample rate & period size changes (to avoid
482 crashes and noise on such transitions).
483 - ignore missing LADSPA paths without ignoring valid LADSPA paths
484 (fixes #208)
485 - Fixed bug in LSCP grammar definition which caused a statement like
486 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
487 practically irrelevant, however it caused problems with the new LSCP
488 shell's auto completion feature).
489
490 Version 1.0.0 (31 July 2009)
491
492 * packaging changes:
493 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
494 causing e.g. the libgig test to fail when
495 "./configure --disable-jack-driver" was used
496 (patch by Alexis Ballier)
497 - fixed compilation with gcc 4.3
498 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
499 - fixed configure so it detects x86_64 (#107)
500 - fixes for building with newer MinGW versions
501 - fix for building with bison 2.4 (#111)
502 - fixed building with libgig installed in a non-standard directory
503 - minor fix in configure for mmsystem.h detection on MinGW
504 - Windows: look for editor plugins and Fantasia using base
505 directory of liblinuxsampler dll (look in the same directory and one
506 directory above)
507 - configure script fix: removed unconditional use of SSE
508 - fixed building with sqlite installed in a non-standard directory
509 - when cross-compiling, don't try to create instruments.db
510 - fix for new mingw-w64 version, which has usleep
511
512 * general changes:
513 - bugfix: on some POSIX systems instrument editor plugins refused to
514 load as we used a non-portable Linux specific struct field
515 (fixes bug #70, patch by Ronald Baljeu)
516 - fixed endless loop which occured when loading an instrument editor
517 plugin DLL on Windows systems failed
518 - fixed memory leaks that occurred when liblinuxsampler was unloaded
519 - optimized the SynchronizedConfig class so it doesn't wait
520 unnecessarily long after an update
521 - added support for notifying instrument editors on note-on / note-off
522 events (e.g. to highlight the pressed keys on the virtual keyboard
523 of gigedit)
524 - added support for triggering notes by instrument editors (see above)
525 - be verbose on DLL load errors (on Linux)
526 - fixed di-harmonic triangle LFO implementation (this LFO implementation
527 is only used by very few systems, most pick the int math
528 implementation, which is usually faster)
529 - fixes for audio drivers with varying buffer sizes
530 - experimental support for running LinuxSampler as a DSSI, LV2 and
531 VST plugin
532 - notification events for stream/voice count statistics are now sent
533 only when there are actual changes
534 - added memory ordering constraints to improve stability on
535 multi-core and multi-cpu systems
536 - maximum voices and disk streams can now be altered at runtime
537 - fixed CPU feature detection on x86_64 (maybe fixes #108)
538 - automatic stacktrace mechanism is now turned off by default and can
539 be switched on by command line option "--stacktrace" (the automatic
540 stacktrace mechanism seems to be broken on most systems at the moment)
541 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
542 a pointer to the launched InstrumentEditor object
543 - added optional 3rd party user data parameter for following
544 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
545 InstrumentEditor::Launch(),
546 InstrumentManager::LaunchInstrumentEditor()
547 - theoretical fix: made SynchronizedConfig follow C++0x memory
548 model more strictly
549 - fixes for using large audio device buffers
550 - Windows: add the installation directory to the DLL search path
551 when loading an editor plugin (solves problems with VST and
552 gigedit on systems with other GTK versions installed)
553 - updated linuxsampler man page
554
555 * audio driver:
556 - removed the nonsense audio channel constraint (which was hard coded to
557 max. 100 audio channels) for most audio drivers
558 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
559 opposed to the LSCP specs
560 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
561 reflected the wrong value
562 - fixed a memory management bug in ASIO driver
563 - Makefile fix: JACK_CFLAGS wasn't used
564 - JACK: use jack_client_open instead of the deprecated
565 jack_client_new
566 - added (experimental) CoreAudio driver
567 - applied old fixes to the ASIO driver that were included in the
568 previous binary release but accidentally never committed to CVS
569 (fixes #117)
570 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
571 win64)
572 - VST: added support for sample rate and buffer size changes
573 - VST: close editor (Fantasia) when the VST is removed
574 - VST: avoid opening Fantasia more than once for each VST instance
575 - VST: export main function as "main" on Linux too (fix for
576 energyXT)
577 - VST: changed number of output channels from one stereo to 16
578 stereo
579 - added channel routing, fxsends and midi maps to the settings
580 stored in the plugin state
581 - performance optimization of AudioChannel::MixTo() and
582 AudioChannel::CopyTo() methods using GCC vector exensions
583 (if available)
584 - ASIO fixes: avoid initializing the device twice, avoid throwing
585 exception when getting parameters from a disconnected device
586
587 * MIDI driver:
588 - added JACK MIDI driver
589 - dispatch bank select as ordinary CC as well, the user might seriously
590 want to (mis)use it for some purpose ("fixed" in all current MIDI
591 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
592 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
593 CoreMidi or AU
594 - fixed mingw-w64 compilation error in MME driver
595 - made program change handling in MIDI thread real-time safe by
596 moving the logic to a non-RT thread
597 - fixed minor memory leak in ALSA driver
598
599 * instruments database:
600 - avoid time consuming samples scanning when adding instruments
601 to the instruments database
602 - added support for handling lost files in the instruments database
603 - Implemented option for adding instruments in separate directories
604 in the instruments database
605 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
606 - work-around for missing fnmatch function on Windows to make
607 instrument database compilable
608 - added instrument database support on Windows
609 works with both standalone mode and VST plugin.
610 the instruments DB file is located in
611 %USERPROFILE%\.linuxsampler\instruments.db which allows different
612 databases for each windows user
613 if no DB is present it automatically creates the .linuxsampler subdir
614 and then creates an empty DB
615 - fixed recursive import, which was broken on Windows
616
617 * Gigasampler format engine:
618 - fixed a memory leak that could happen when a channel was deleted
619 while notes were playing
620 - made it possible to load an instrument even if the audio thread
621 isn't running
622 - added partial support for the "Controller Triggered" MIDI rule,
623 enough for piano gigs with pedal noise samples
624 - minor fix: only mark FX sends as being modified if really the
625 respective FX send MIDI controller was used
626 - added support for GM global device volume SysEx message
627 (can be selected at compile time to either apply globally to the
628 whole sampler [default] or only to the sampler channels that are
629 connected to the respective MIDI input port the SysEx message arrived
630 on)
631 - bugfix: notes triggered at position 0 in the audio buffer were
632 sometimes wrongly killed in the same buffer, causing no sound to
633 be played
634 - added support for chromatic / drumkit mode Roland GS Sysex message
635 which is usally used to switch a part between chromatic sounds and
636 drumkit sounds (as opposed to their common default setting of MIDI
637 part 10 being a drumkit part and all other ones chromatic parts), in
638 LS however one can switch between the first 16 MIDI instrument maps
639 defined for the sampler
640 - made it possible to create multiple sample channels even if the
641 audio thread isn't running
642 - fixed crash when removing channel with active voices (#116)
643 - bugfix: on sample reference changes (instrument editor), only
644 un-cache the respective sample if it's really not used by any
645 sampler engine anymore
646 - re-cache samples in case they were changed by an instrument editor,
647 e.g. when a sample was added while playing (#82)
648 - fixed hanging notes which occured when note-off event had the exact
649 same time stamp as the voice's note-on event and occured both in the
650 same audio fragment cycle (fixes bug #112)
651 - added support for the "fine tune" and "pitch bend range"
652 instrument-level gig parameters
653 - fixed minor artifacts in pitch bend handling
654 - added support for GS Reset SysEx message
655 - allow gig files to use unlimited downward pitch shifting
656 - added a limit check for upward pitch shifting
657 - bugfix: sometimes, when playing a note twice fast, the second
658 note was silent
659 - fixed crash happening when a pitch bend event arrived at the
660 same time a new instrument was loading
661
662 * LSCP server:
663 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
664 react on MIDI data arriving on certain sampler channels (so far only
665 Note-On and Note-Off events are sent via this LSCP event)
666 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
667 react on MIDI data arriving on certain MIDI input devices (so far only
668 Note-On and Note-Off events are sent via this LSCP event)
669 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
670 SET DB_INSTRUMENT FILE_PATH
671 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
672 frontends to send MIDI messages to specific sampler channel
673 - added two additional fields to GET FILE INSTRUMENT INFO command -
674 KEY_BINDINGS and KEYSWITCH_BINDINGS
675 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
676 was incorrect
677 - Optimized the retrieval of the MIDI instrument mappings
678 - added new LSCP command "SET VOICES" to globally alter the maximum
679 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
680 be triggered respectively
681 - added new LSCP command "SET STREAMS" to globally alter the maximum
682 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
683 which will be triggered respectively
684 - bugfix: retry if "select" returns EINTR (this fixes a crash when
685 a gigedit file dialog is opened)
686 - close all connections when LSCPServer is deleted
687 - hard close of all sockets on exit
688 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
689 driver
690
691 * Bug fixes:
692 - fixed a crash which occurs when removing a sampler channel waiting
693 to start instrument loading after another channel
694 - fixed a crash which occurs when removing a sampler channel with
695 instrument loading in progress (bug #113)
696 - fixed termination caused by uncaught exception when adding MIDI
697 instrument with PERSISTENT load mode
698 - fixed possible iterator invalidations when resetting the sampler
699 - fixed memory leaks when issuing the following LSCP commands:
700 GET AUDIO_OUTPUT_DRIVER INFO
701 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
702 GET MIDI_INPUT_DRIVER INFO
703 GET MIDI_INPUT_DRIVER_PARAMETER INFO
704 - fixed possible compilation error when sqlite is not present
705 - fixed orphaned pointers when setting maximum voices limit (bug #118)
706 - fixed crash when changing the audio output device of a sampler
707 channel with loaded instrument and start playing notes
708 - fixed endless loop in Engine::SuspendAll() (bug #120)
709 - fixed a low-level atomic load function that was broken on 64-bit
710 PowerPC, which probably could cause crashes on that platform
711 - fixed a memory management error which could cause a crash when a
712 plugin was unloaded
713 - bugfix: two private structs had the same name, which could cause
714 problems if the linker chose the wrong constructor
715 - fixed low-level ConditionServer usage bug that caused lockups on
716 Windows
717
718
719 Version 0.5.1 (6 December 2007)
720
721 * packaging changes:
722 - added autoconf checks for pthread library
723 - added autoconf check for pthread bug found on certain NPTL-enabled
724 glibc versions (see Gentoo bug report #194076)
725 - added autoconf checks for MS Windows
726
727 * general changes:
728 - bugfix: the thread used by an editor plugin didn't die when the
729 editor closed
730 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
731 out all the space. operator--() did not apply size_mask after
732 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
733 order to avoid problems with the _NonVolatileReader functions.
734 - bugfix: Stream.h: added a missing divide by BytesPerSample in
735 GetWriteSpace(). Since this function is currently only used in
736 the stream's qsort() compare function, it didn't trigger any
737 bugs.
738 - Resampler.h, Synthesizer.h: cubic interpolation now works in
739 24bit mode too. Faster method to read 24bit words on little
740 endian machines (x86): replaced 3 byte reads + shifts with a 1
741 unaligned 32bit read and shift
742 - experimental support for MS Windows (MIDI input via MME, AUDIO
743 output via ASIO)
744 - made handling of SIGINT signal (Ctrl-C) a bit more robust
745 - support for monitoring the total number of active disk streams
746 (new LSCP commands: GET TOTAL_STREAM_COUNT,
747 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
748
749 * AUDIO driver:
750 - added Windows ASIO low latency audio driver
751
752 * MIDI driver:
753 - added MME Windows MIDI driver
754
755 * LSCP server:
756 - added support for Windows style path / filenames, however with
757 forward slash path separators instead of backslash
758 (i.e. "C:/foo/bar.gig")
759 - allow naughty liblscp to send non-string device parameters within
760 apostrophes as well
761 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
762 "LIST FILE INSTRUMENTS <file>" and
763 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
764 about an arbitrary instrument file on the system where the sampler is
765 running on
766
767 Version 0.5.0 (15 October 2007)
768
769 * packaging changes:
770 - config.h is not going to be installed along with liblinuxsampler's
771 API header files anymore
772 - only the API relevant header (and source) files will be exported to
773 the Doxygen API documentation (explicitly listed in Doxyfile.in)
774 - added completely new XCode project files for Mac OSX which is now
775 capable to execute our autoconf environment, thus no need anymore
776 to maintain the compile time configuration file (osx/version.h) for
777 OSX manually (patch by Toshi Nagata)
778 - fixed buggy boolean --enable-foo / --disable-foo configure script
779 parameters
780 - global.h now only covers global definitions that are needed for the
781 C++ API header files, all implementation internal global definitions
782 are now in global_private.h
783 - atomic.h is not exposed to the C++ API anymore
784 - no need to include config.h anymore for using LS's API header files
785 - fixed warnings in API doc generation
786
787 * general changes:
788 - replaced the old, confusing MIDI program change mechanism by a
789 flexible MIDI instrument mapper which allows to map arbitrary
790 (MIDI bank, MIDI program) pairs with arbitrary
791 (engine type, instrument file, file index) triplets which will be
792 loaded on the respective channel when such MIDI program change
793 messages arrive, beside that, each entry allows to define a life-time
794 strategy for the instrument, so the user can define whether the
795 instrument should i.e. be permanently loaded (to be able to switch
796 quickly among sounds) or i.e. loaded just on demand when the
797 respective program change arrives (to safe RAM space), as well as a
798 global volume factor for each entry, so the user can adjust the volume
799 dynamic of his mapped instrument collection without having to modify
800 the instrument files, also one can manage arbitrary amount of such
801 MIDI instrument maps and assign each sampler channel individually
802 a certain map, so that i.e. separation of normal instruments and
803 drumkits is possible
804 - new notification events for tracking changes to audio/MIDI devices,
805 MIDI instrument maps, MIDI instruments, FX sends, global volume.
806 - sampler was limited to load max. 200 instruments in the background
807 due to a constant size RingBuffer FIFO which is now replaced by a
808 dynamic (unlimited) size std::list FIFO
809 - added FX sends, these allow to route audio signals to arbitrary audio
810 output channels for being processed by external effect processors
811 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
812 controllers
813 - global (sampler wide) volume can now be controlled at runtime
814 - Implemented new, improved notification system
815 - fixed compilation errors regarding OSX
816 (patch by Toshi Nagata)
817 - implemented instruments database
818 - added support for escape sequences to the instruments database
819 - added highly experimental support for on-the-fly instrument editing
820 within the sampler's process (by using instrument editor plugins),
821 you'll notice the new "Registered instrument editors:" message on
822 startup, added a new LSCP command:
823 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
824 to spawn a matching instrument editor for the instrument on the
825 given sampler channel, the plugin path can be overridden at compile
826 time with ./configure --enable-plugin-dir=/some/dir
827 - added experimental code for synchronizing instrument editors hosted
828 in the sampler's process to safely edit instruments while playing
829 without a crash (hopefully) by either suspending single regions
830 wherever possible or if unavoidable whole engine(s)
831 - fixed several issues in fundamental "Thread" class: set scheduling
832 policy and priority on thread level, set a minimum stack size for
833 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
834 threads simply inherited properties of starting thread instead of
835 setting their own policy and priority
836 - minor fix in our automatic stack trace mechanism on crashes, the
837 main process did not wait for the stack trace process to finish
838 its output
839 - fixed some minor memory leaks
840 - reenabled assembly features support, at the moment only for
841 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
842 - minor assembly fix in x86 features detection (don't use the PIC
843 register, to avoid relocations in the text segment at runtime)
844 - POSIX callback functions of Thread.h are hidden
845
846 * MIDI driver:
847 - dispatch bank select (MSB and LSB) messages
848
849 * audio driver:
850 - the ALSA audio output driver parameters now reflect the correct
851 parameter value ranges for the respective selected sound card
852 (patch by Till Wimmer, a bit fixed and extended)
853
854 * Gigasampler format engine:
855 - if a filter is used and EG2 finishes before EG1, let the voice
856 die when EG2 has finished (this fixes a problem with clicks and
857 voice starvation for some gigs)
858 - playback is no longer disabled during instrument loading
859 - all notes playing on a channel that changes its instrument keep
860 playing with the old instrument until they get a note off
861 command
862 - EG fix: a release value of zero could cause noises or crash
863 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
864 - EG fine tuning: when attack is zero the EG starts at a level
865 above max sustain level, which means that there is a decay phase
866 even if sustain is 100%
867 - more EG fixes: the level could sometimes go below zero and cause
868 noises or crashes
869 - minor fix of EGDecay (patch by Toshi Nagata)
870 - fixed compiler error when --enable-override-filter-type was
871 supplied to the configure script (fixes #46)
872 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
873 instead of a fix value
874 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
875 127 (solo mode) only kill voices if the respective mode really
876 changed
877
878 * LSCP server:
879 - fixed compile time error for old Bison versions
880 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
881 - parser now supports extended ASCII character set
882 (up to ASCII code 255, i.e. includes now umlauts and accents)
883 - filename arguments in LSCP commands now allow to use escape
884 sequences, that is directly literal as one of: \', \", \\, \n, \r,
885 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
886 code value like \xf2) (fixes bug #24)
887 - the following LSCP commands now also support escape sequences for at
888 least one of their text-based parameters (i.e. name, description):
889 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",

895 - returns verbose syntax errors (line and column where syntax error
896 occured, the unexpected character and the actually expected, possible
897 character(s), the latter only if less than 5 possibilities)
898 - made sure that LSCP syntax is not affected by gigedit locale
899 settings
900 - bugfix regarding strings parameter lists: all comma separated lists
901 of strings were treated as being one string containing commas
902 (fixes #57)
903
904 * Bug fixes:
905 - fixed crash occurring on certain LSCP scripts (Bug 39)
906 - another thread safety fix for lscp "load engine" and "set
907 channel audio output device"
908 - fixed a crash which occurs when reassigning the same engine
909 on a sampler channel with connected MIDI device
910 - fixed a crash which occurs when changing the number of ports of a MIDI
911 device connected to a sampler channel to number less then or equal
912 to the index of the port to which the sampler channel is connected.
913 - The previous bindings were not been disconnected when altering
914 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
915 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
916 - The active stream/voice count statistic was incorrect.
917 - notification events were not been sent for some sampler
918 channel changes
919 - added default min and max values to restrict the number of allowed
920 audio output channels and MIDI input ports
921 - the connection to the PCM interface is now closed when destroying
922 an audio output device
923 - files with slash in their path or filename could not be loaded
924
925 * test cases:
926 - updated and fixed (haven't been touched in a while)
927
928 Version 0.4.0 (24 November 2006)
929
930 * packaging changes:
931 - changed deprecated copyright attribute to license; added ldconfig
932 to post-(un)install steps; added devel package for liblinuxsampler;
933 to linuxsampler.spec (RPM)
934 - install necessary development header files for allowing 3rd party
935 applications to link against liblinuxsampler
936 - liblinuxsampler's API documentation can be generated with 'make docs'
937 (Doxygen required)
938 - added benchmark to automatically detect the best triangle LFO
939 implementation (currently either an integer math solution or a
940 di-harmonic approximation), automatic detection can be overriden
941 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
942 configure script argument though (mandatory for cross-compilation)
943 - do not automatically pick optimized gcc flags if the user already
944 provided some on his own (as CXXFLAGS)
945 - added compile time option to disable processing of All-Notes-Off MIDI
946 messages
947 - added compile time options to allow disabling the various audio and
948 MIDI drivers
949 - fixed automatic GCC CPU switch detection on PPC
950 (patch by Ebrahim Mayat)
951
952 * Gigasampler format engine:
953 - extensive synthesis optimization
954 (reimplementation of EGs and LFO(s), removed synthesis parameter
955 prerendering and the synthesis parameter matrix in general, splitting
956 each audio fragment into subfragments now where each subfragment uses
957 constant pitch and filter coefficients. The volume coefficient is
958 linearly interpolated inside a subfragment, unless
959 --disable-interpolate-volume is set.)
960 - fine tuning of the EG modulation parameters
961 - improved filter cutoff calculation by adding support for the
962 following gig parameters: Cutoff freq (used when no cutoff
963 controller is defined), Control invert, Minimum cutoff, Velocity
964 curve and Velocity range. The keyboard tracking now scales
965 cutoff frequency instead of resonance.
966 - added support for gig parameter Resonance.
967 - fixed bug in sysex handling (patch by Juan Linietsky)
968 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
969 which can be overridden with --enable-global-attenuation
970 - EG fixes: made the length of "attack hold" stage more
971 accurate. Release stage can now start before attack stage
972 ends. Cancel release didn't work when sustain was zero. Attack
973 time now has a minimal value to prevent clicks.
974 - fixed pitch changes larger than one octave
975 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
976 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
977 all modes can be altered via standard GM messages, that is CC5 for
978 altering portamento time, CC65 for enabling / disabling portamento
979 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
980 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
981 parameter) and crossfade
982 - added support for the "attenuation controller threshold" gig
983 parameter
984 - added smoothing of volume changes caused by control change
985 messages
986 - sample loop parameters are now taken from the DimensionRegion
987 instead of the wave chunk
988 - fixed keyswitching for v3 gigs with a number of keyswitch splits
989 not equal to a power of two
990 - reimplementation of the filter algorithm. The new filter is more
991 accurate and supports all gig filter types, including bandreject
992 and lowpass turbo.
993 - real support for 24 bit samples - samples are not truncated to
994 16 bits anymore
995 - support for aftertouch (channel pressure, not polyphonic
996 aftertouch)
997 - LFO1 behaviour fixed (dampening from max volume instead of
998 amplifying from 0)
999
1000 * LSCP server:
1001 - fixed application exit on broken pipe error (fixes bug #20)
1002 - fixed the notification messages delay due to lack of
1003 network activity (fixes bug #26)
1004 - fixed parser bug which occured on space(s) within device parameters
1005 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1006
1007 * audio driver:
1008 - added aRts audio output driver (by no means RT safe)
1009
1010 * MIDI driver:
1011 - fixed legacy sysex code which caused dispatching of MIDI SysEx
1012 messages several times instead of once
1013 - API extension for MIDI drivers which already supply exact time stamps
1014 for events (i.e. for offline rendering based MIDI drivers)
1015 - added checks for bad MIDI data
1016
1017 * linuxsampler application:
1018 - show available sampler engine types on startup
1019
1020 * general changes:
1021 - support for muting sampler channels and solo mode of the same, two new
1022 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1023 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1024 introduced for this, the behavior is the same like on a mixer console
1025 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1026 --enable-process-muted-channels which can be used to enable the
1027 processing of muted channels.
1028 - support for sostenuto pedal
1029 - support for monitoring the total number of active voices
1030 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1031 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1032 - fixed some memory management errors
1033 - fixed some concurrency problems that could lead to crashes when
1034 LSCP commands were executed
1035 - fixed crash when instrument loading failed previously on the same
1036 sampler channel (fixes bug #36)
1037
1038 Version 0.3.3 (15 July 2005)
1039
1040 * packaging changes:
1041 - fixed compilation with gcc 4.0
1042
1043 * Gigasampler format engine:
1044 - LFO preprocessing was performed even though the respective LFO was
1045 disabled by the instrument patch (minor efficiency fix)
1046 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1047 for volume ramp downs in the same fragment (needed for current voice
1048 stealing implementation) then simply inform the user with a warning
1049 about possible click sounds and reduce the volume ramp down
1050 appropriately instead of cancelling the audio device connection
1051
1052 Version 0.3.2 (24 June 2005)
1053
1054 * packaging changes:
1055 - updated autotools build files to compile on OS X
1056 (conditional compilation of CoreMIDI and MidiShare drivers)
1057 - hand-crafted assembly optimization code can be disabled with
1058 './configure --disable-asm' (definitely not recommended)
1059 - fixed 'make dist' rule to include all necessary files
1060 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1061 (due to 'dist-bzip2' automake option)
1062
1063 * Gigasampler format engine:
1064 - support for the gig parameters for "release velocity response" curves
1065 - fine tuning of the EGADSR envelope
1066 - volume of release triggered samples now depends on note-on velocity,
1067 note length and gig parameter "release trigger decay" instead of
1068 note-off velocity.
1069 - revised voice stealing
1070 (fixes crash and endless loop caused by voice stealing)
1071 - don't reset scale tuning on instrument or audio output device change
1072 - handle key group conflicts right at the beginning of each fragment
1073 instead of when the respective voice is actually launched
1074 (fixes undefined behavior if stolen voices belonged to a key group -
1075 this case was followed by a "killed voice survived" error message)
1076 - fixed minor issue with null/silence samples
1077 (those stole voices even though they don't need a voice at all which
1078 resulted in "voice stealing didn't work out" messages)
1079 - don't reset volume, pan, pitch and MIDI controller values on
1080 instrument or audio output device change
1081
1082 * LSCP server:
1083 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1084 - fixed LSCP event "CHANNEL_INFO" notification
1085 (e.g. did not notify on volume changes or MIDI program change events)
1086
1087 * linuxsampler application:
1088 - added command line parameters --lscp-addr and --lscp-port to override
1089 default IP address and port of LSCP server
1090
1091 Version 0.3.1 (24 May 2005)
1092
1093 * initial release
