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

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

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

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
107 * Gigasampler format engine:
108 - implemented the "round robin keyboard" dimension
109 - fixed round robin and random dimensions for cases when number of
110 dimension zones is not a power of two
111 - made round robin use a counter for each region instead of each
112 key
113 - bugfix: pitch LFO controller "internal+aftertouch" was broken
114 - bugfix: filter keyboard tracking was broken
115 - filter performance fix (an unnecessary copy was made of the
116 filter parameters in each sub fragment)
117 - handle special case when pan parameter in gig file has max or
118 min value
119 - Exclusive Groups: don't ever stop voices of the same note,
120 doesn't sound naturally with a drumkit
121 - fixed EG1 modulation when attack or release is zero
122 - Fixed support for 'aftertouch' attenuation controller.
123 - Fixed crash that happened with velocity split sounds under certain
124 conditions (see also previous commit on libgig).
125
126 * SFZ format engine:
127 - Initial implementation (not usable yet)
128 - added support for v2 multiple stage envelope generators

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

322 Linux, the Fantasia jar should be placed in <prefix>/share/java)
323 - VST: fixed crashes on Linux Ardour and EnergyXT
324 - DSSI bugfix: it wasn't possible to change engine type. The MIDI
325 port and audio channel routing for DSSI plugins are now visible.

327 and event
328 - LV2: lv2 package 1.0 is now required to build the LV2 plugin

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

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

411 * LSCP shell:
412 - Added support for auto correction of obvious and trivial syntax mistakes.
413 - Added support for auto completion by tab key.
414 - Show currently available auto completion while typing.
415 - Added support for browsing command history with up / down keys.
416 - Show all possible next symbols immediately right to the current command
417 line while typing (no double tab required for this feature, as it would
418 be the case in other shells).
419 - Added support for moving cursor left/right with arrow keys.
420 - Added support for built-in LSCP reference documentation, which will
421 automatically show the relevant LSCP reference section on screen as soon
422 as one specific LSCP command was detected while typing on the command
423 line.
424
425 * Bug fixes:
426 - Fixed crash which may occur when MIDI key + transpose is out of range
427 - minor valgrind fixes
428 - fixed crash which occurred when changing an already deployed sampler
429 channel to a different engine type
430 - fixed crash when deleting a sampler channel or changing engine
431 type while an instrument load was in progress
432 - bugfix: playing a note while changing the instrument could cause
433 a crash, or give "Handing back unknown region" error messages
434 - bugfix: calling SET VOICES (which Fantasia does on start and
435 refresh) could cause instruments to be unloaded
436 - Mac OS X: fixed name collision of enum in EffectControl and
437 wrong name of destructor in AudioOutputDeviceCoreAudio.cpp
438 - Mac OS X: fixed hanging threads
439 - Windows: disabled the previous thread fix on non-Mac systems, as
440 it caused hanging threads on Windows
441 - Fixed possible crashes due to corrupted MIDI/audio device list
442 after MIDI/audio device creation failure
443 - When creating MIDI instrument map entries with "PERSISTENT" type, the
444 instruments were uselessly precached with zero samples, however it still
445 took the full preloading time and on 1st program change the respective
446 instrument was completely reloaded again.
447 - fixed handling of rapid bank select and program change messages
448 sent to the same sampler channel (patch from the Open Octave
449 project, slightly adjusted)
450 - fixed crash when trying to create an effect instance with controls
451 which min and/or max values depend on the sample rate
452 - fixed bug #162
453 - bugfix: LADSPA_PATH was not evaluated correctly when containing
454 multiple paths (#165)
455 - thread safety fixes for the instrument loading thread
456 - bugfix: instrument loading crashed for sfz and sf2 in Ardour
457 (#176)
458 - more thread safety fixes for the instrument loading thread
459 - sfz/sf2 engine: fixed crash when using small audio fragment size
460 - Mac OS X: fixed crash when unloading plugin on 10.7 and later
461 - Mac OS X: fixed process hang when unloading 32-bit plugin (bug
462 introduced in previous fix)
463 - fixed crash when a channel received a program change while
464 playing a note in a key group
465 - fixed erroneous error message piping in VoiceBase.h
466 (labelled "Disk stream not available in time")
467 - Update effects on sample rate & period size changes (to avoid
468 crashes and noise on such transitions).
469 - ignore missing LADSPA paths without ignoring valid LADSPA paths
470 (fixes #208)
471 - Fixed bug in LSCP grammar definition which caused a statement like
472 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
473 practically irrelevant, however it caused problems with the new LSCP
474 shell's auto completion feature).
475
476 Version 1.0.0 (31 July 2009)
477
478 * packaging changes:
479 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
480 causing e.g. the libgig test to fail when
481 "./configure --disable-jack-driver" was used
482 (patch by Alexis Ballier)
483 - fixed compilation with gcc 4.3
484 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
485 - fixed configure so it detects x86_64 (#107)
486 - fixes for building with newer MinGW versions
487 - fix for building with bison 2.4 (#111)
488 - fixed building with libgig installed in a non-standard directory
489 - minor fix in configure for mmsystem.h detection on MinGW
490 - Windows: look for editor plugins and Fantasia using base
491 directory of liblinuxsampler dll (look in the same directory and one
492 directory above)
493 - configure script fix: removed unconditional use of SSE
494 - fixed building with sqlite installed in a non-standard directory
495 - when cross-compiling, don't try to create instruments.db
496 - fix for new mingw-w64 version, which has usleep
497
498 * general changes:
499 - bugfix: on some POSIX systems instrument editor plugins refused to
500 load as we used a non-portable Linux specific struct field
501 (fixes bug #70, patch by Ronald Baljeu)
502 - fixed endless loop which occured when loading an instrument editor
503 plugin DLL on Windows systems failed
504 - fixed memory leaks that occurred when liblinuxsampler was unloaded
505 - optimized the SynchronizedConfig class so it doesn't wait
506 unnecessarily long after an update
507 - added support for notifying instrument editors on note-on / note-off
508 events (e.g. to highlight the pressed keys on the virtual keyboard
509 of gigedit)
510 - added support for triggering notes by instrument editors (see above)
511 - be verbose on DLL load errors (on Linux)
512 - fixed di-harmonic triangle LFO implementation (this LFO implementation
513 is only used by very few systems, most pick the int math
514 implementation, which is usually faster)
515 - fixes for audio drivers with varying buffer sizes
516 - experimental support for running LinuxSampler as a DSSI, LV2 and
517 VST plugin
518 - notification events for stream/voice count statistics are now sent
519 only when there are actual changes
520 - added memory ordering constraints to improve stability on
521 multi-core and multi-cpu systems
522 - maximum voices and disk streams can now be altered at runtime
523 - fixed CPU feature detection on x86_64 (maybe fixes #108)
524 - automatic stacktrace mechanism is now turned off by default and can
525 be switched on by command line option "--stacktrace" (the automatic
526 stacktrace mechanism seems to be broken on most systems at the moment)
527 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
528 a pointer to the launched InstrumentEditor object
529 - added optional 3rd party user data parameter for following
530 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
531 InstrumentEditor::Launch(),
532 InstrumentManager::LaunchInstrumentEditor()
533 - theoretical fix: made SynchronizedConfig follow C++0x memory
534 model more strictly
535 - fixes for using large audio device buffers
536 - Windows: add the installation directory to the DLL search path
537 when loading an editor plugin (solves problems with VST and
538 gigedit on systems with other GTK versions installed)
539 - updated linuxsampler man page
540
541 * audio driver:
542 - removed the nonsense audio channel constraint (which was hard coded to
543 max. 100 audio channels) for most audio drivers
544 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
545 opposed to the LSCP specs
546 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
547 reflected the wrong value
548 - fixed a memory management bug in ASIO driver
549 - Makefile fix: JACK_CFLAGS wasn't used
550 - JACK: use jack_client_open instead of the deprecated
551 jack_client_new
552 - added (experimental) CoreAudio driver
553 - applied old fixes to the ASIO driver that were included in the
554 previous binary release but accidentally never committed to CVS
555 (fixes #117)
556 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
557 win64)
558 - VST: added support for sample rate and buffer size changes
559 - VST: close editor (Fantasia) when the VST is removed
560 - VST: avoid opening Fantasia more than once for each VST instance
561 - VST: export main function as "main" on Linux too (fix for
562 energyXT)
563 - VST: changed number of output channels from one stereo to 16
564 stereo
565 - added channel routing, fxsends and midi maps to the settings
566 stored in the plugin state
567 - performance optimization of AudioChannel::MixTo() and
568 AudioChannel::CopyTo() methods using GCC vector exensions
569 (if available)
570 - ASIO fixes: avoid initializing the device twice, avoid throwing
571 exception when getting parameters from a disconnected device
572
573 * MIDI driver:
574 - added JACK MIDI driver
575 - dispatch bank select as ordinary CC as well, the user might seriously
576 want to (mis)use it for some purpose ("fixed" in all current MIDI
577 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
578 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
579 CoreMidi or AU
580 - fixed mingw-w64 compilation error in MME driver
581 - made program change handling in MIDI thread real-time safe by
582 moving the logic to a non-RT thread
583 - fixed minor memory leak in ALSA driver
584
585 * instruments database:
586 - avoid time consuming samples scanning when adding instruments
587 to the instruments database
588 - added support for handling lost files in the instruments database
589 - Implemented option for adding instruments in separate directories
590 in the instruments database
591 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
592 - work-around for missing fnmatch function on Windows to make
593 instrument database compilable
594 - added instrument database support on Windows
595 works with both standalone mode and VST plugin.
596 the instruments DB file is located in
597 %USERPROFILE%\.linuxsampler\instruments.db which allows different
598 databases for each windows user
599 if no DB is present it automatically creates the .linuxsampler subdir
600 and then creates an empty DB
601 - fixed recursive import, which was broken on Windows
602
603 * Gigasampler format engine:
604 - fixed a memory leak that could happen when a channel was deleted
605 while notes were playing
606 - made it possible to load an instrument even if the audio thread
607 isn't running
608 - added partial support for the "Controller Triggered" MIDI rule,
609 enough for piano gigs with pedal noise samples
610 - minor fix: only mark FX sends as being modified if really the
611 respective FX send MIDI controller was used
612 - added support for GM global device volume SysEx message
613 (can be selected at compile time to either apply globally to the
614 whole sampler [default] or only to the sampler channels that are
615 connected to the respective MIDI input port the SysEx message arrived
616 on)
617 - bugfix: notes triggered at position 0 in the audio buffer were
618 sometimes wrongly killed in the same buffer, causing no sound to
619 be played
620 - added support for chromatic / drumkit mode Roland GS Sysex message
621 which is usally used to switch a part between chromatic sounds and
622 drumkit sounds (as opposed to their common default setting of MIDI
623 part 10 being a drumkit part and all other ones chromatic parts), in
624 LS however one can switch between the first 16 MIDI instrument maps
625 defined for the sampler
626 - made it possible to create multiple sample channels even if the
627 audio thread isn't running
628 - fixed crash when removing channel with active voices (#116)
629 - bugfix: on sample reference changes (instrument editor), only
630 un-cache the respective sample if it's really not used by any
631 sampler engine anymore
632 - re-cache samples in case they were changed by an instrument editor,
633 e.g. when a sample was added while playing (#82)
634 - fixed hanging notes which occured when note-off event had the exact
635 same time stamp as the voice's note-on event and occured both in the
636 same audio fragment cycle (fixes bug #112)
637 - added support for the "fine tune" and "pitch bend range"
638 instrument-level gig parameters
639 - fixed minor artifacts in pitch bend handling
640 - added support for GS Reset SysEx message
641 - allow gig files to use unlimited downward pitch shifting
642 - added a limit check for upward pitch shifting
643 - bugfix: sometimes, when playing a note twice fast, the second
644 note was silent
645 - fixed crash happening when a pitch bend event arrived at the
646 same time a new instrument was loading
647
648 * LSCP server:
649 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
650 react on MIDI data arriving on certain sampler channels (so far only
651 Note-On and Note-Off events are sent via this LSCP event)
652 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
653 react on MIDI data arriving on certain MIDI input devices (so far only
654 Note-On and Note-Off events are sent via this LSCP event)
655 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
656 SET DB_INSTRUMENT FILE_PATH
657 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
658 frontends to send MIDI messages to specific sampler channel
659 - added two additional fields to GET FILE INSTRUMENT INFO command -
660 KEY_BINDINGS and KEYSWITCH_BINDINGS
661 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
662 was incorrect
663 - Optimized the retrieval of the MIDI instrument mappings
664 - added new LSCP command "SET VOICES" to globally alter the maximum
665 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
666 be triggered respectively
667 - added new LSCP command "SET STREAMS" to globally alter the maximum
668 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
669 which will be triggered respectively
670 - bugfix: retry if "select" returns EINTR (this fixes a crash when
671 a gigedit file dialog is opened)
672 - close all connections when LSCPServer is deleted
673 - hard close of all sockets on exit
674 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
675 driver
676
677 * Bug fixes:
678 - fixed a crash which occurs when removing a sampler channel waiting
679 to start instrument loading after another channel
680 - fixed a crash which occurs when removing a sampler channel with
681 instrument loading in progress (bug #113)
682 - fixed termination caused by uncaught exception when adding MIDI
683 instrument with PERSISTENT load mode
684 - fixed possible iterator invalidations when resetting the sampler
685 - fixed memory leaks when issuing the following LSCP commands:
686 GET AUDIO_OUTPUT_DRIVER INFO
687 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
688 GET MIDI_INPUT_DRIVER INFO
689 GET MIDI_INPUT_DRIVER_PARAMETER INFO
690 - fixed possible compilation error when sqlite is not present
691 - fixed orphaned pointers when setting maximum voices limit (bug #118)
692 - fixed crash when changing the audio output device of a sampler
693 channel with loaded instrument and start playing notes
694 - fixed endless loop in Engine::SuspendAll() (bug #120)
695 - fixed a low-level atomic load function that was broken on 64-bit
696 PowerPC, which probably could cause crashes on that platform
697 - fixed a memory management error which could cause a crash when a
698 plugin was unloaded
699 - bugfix: two private structs had the same name, which could cause
700 problems if the linker chose the wrong constructor
701 - fixed low-level ConditionServer usage bug that caused lockups on
702 Windows
703
704
705 Version 0.5.1 (6 December 2007)
706
707 * packaging changes:
708 - added autoconf checks for pthread library
709 - added autoconf check for pthread bug found on certain NPTL-enabled
710 glibc versions (see Gentoo bug report #194076)
711 - added autoconf checks for MS Windows
712
713 * general changes:
714 - bugfix: the thread used by an editor plugin didn't die when the
715 editor closed
716 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
717 out all the space. operator--() did not apply size_mask after
718 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
719 order to avoid problems with the _NonVolatileReader functions.
720 - bugfix: Stream.h: added a missing divide by BytesPerSample in
721 GetWriteSpace(). Since this function is currently only used in
722 the stream's qsort() compare function, it didn't trigger any
723 bugs.
724 - Resampler.h, Synthesizer.h: cubic interpolation now works in
725 24bit mode too. Faster method to read 24bit words on little
726 endian machines (x86): replaced 3 byte reads + shifts with a 1
727 unaligned 32bit read and shift
728 - experimental support for MS Windows (MIDI input via MME, AUDIO
729 output via ASIO)
730 - made handling of SIGINT signal (Ctrl-C) a bit more robust
731 - support for monitoring the total number of active disk streams
732 (new LSCP commands: GET TOTAL_STREAM_COUNT,
733 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
734
735 * AUDIO driver:
736 - added Windows ASIO low latency audio driver
737
738 * MIDI driver:
739 - added MME Windows MIDI driver
740
741 * LSCP server:
742 - added support for Windows style path / filenames, however with
743 forward slash path separators instead of backslash
744 (i.e. "C:/foo/bar.gig")
745 - allow naughty liblscp to send non-string device parameters within
746 apostrophes as well
747 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
748 "LIST FILE INSTRUMENTS <file>" and
749 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
750 about an arbitrary instrument file on the system where the sampler is
751 running on
752
753 Version 0.5.0 (15 October 2007)
754
755 * packaging changes:
756 - config.h is not going to be installed along with liblinuxsampler's
757 API header files anymore
758 - only the API relevant header (and source) files will be exported to
759 the Doxygen API documentation (explicitly listed in Doxyfile.in)
760 - added completely new XCode project files for Mac OSX which is now
761 capable to execute our autoconf environment, thus no need anymore
762 to maintain the compile time configuration file (osx/version.h) for
763 OSX manually (patch by Toshi Nagata)
764 - fixed buggy boolean --enable-foo / --disable-foo configure script
765 parameters
766 - global.h now only covers global definitions that are needed for the
767 C++ API header files, all implementation internal global definitions
768 are now in global_private.h
769 - atomic.h is not exposed to the C++ API anymore
770 - no need to include config.h anymore for using LS's API header files
771 - fixed warnings in API doc generation
772
773 * general changes:
774 - replaced the old, confusing MIDI program change mechanism by a
775 flexible MIDI instrument mapper which allows to map arbitrary
776 (MIDI bank, MIDI program) pairs with arbitrary
777 (engine type, instrument file, file index) triplets which will be
778 loaded on the respective channel when such MIDI program change
779 messages arrive, beside that, each entry allows to define a life-time
780 strategy for the instrument, so the user can define whether the
781 instrument should i.e. be permanently loaded (to be able to switch
782 quickly among sounds) or i.e. loaded just on demand when the
783 respective program change arrives (to safe RAM space), as well as a
784 global volume factor for each entry, so the user can adjust the volume
785 dynamic of his mapped instrument collection without having to modify
786 the instrument files, also one can manage arbitrary amount of such
787 MIDI instrument maps and assign each sampler channel individually
788 a certain map, so that i.e. separation of normal instruments and
789 drumkits is possible
790 - new notification events for tracking changes to audio/MIDI devices,
791 MIDI instrument maps, MIDI instruments, FX sends, global volume.
792 - sampler was limited to load max. 200 instruments in the background
793 due to a constant size RingBuffer FIFO which is now replaced by a
794 dynamic (unlimited) size std::list FIFO
795 - added FX sends, these allow to route audio signals to arbitrary audio
796 output channels for being processed by external effect processors
797 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
798 controllers
799 - global (sampler wide) volume can now be controlled at runtime
800 - Implemented new, improved notification system
801 - fixed compilation errors regarding OSX
802 (patch by Toshi Nagata)
803 - implemented instruments database
804 - added support for escape sequences to the instruments database
805 - added highly experimental support for on-the-fly instrument editing
806 within the sampler's process (by using instrument editor plugins),
807 you'll notice the new "Registered instrument editors:" message on
808 startup, added a new LSCP command:
809 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
810 to spawn a matching instrument editor for the instrument on the
811 given sampler channel, the plugin path can be overridden at compile
812 time with ./configure --enable-plugin-dir=/some/dir
813 - added experimental code for synchronizing instrument editors hosted
814 in the sampler's process to safely edit instruments while playing
815 without a crash (hopefully) by either suspending single regions
816 wherever possible or if unavoidable whole engine(s)
817 - fixed several issues in fundamental "Thread" class: set scheduling
818 policy and priority on thread level, set a minimum stack size for
819 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
820 threads simply inherited properties of starting thread instead of
821 setting their own policy and priority
822 - minor fix in our automatic stack trace mechanism on crashes, the
823 main process did not wait for the stack trace process to finish
824 its output
825 - fixed some minor memory leaks
826 - reenabled assembly features support, at the moment only for
827 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
828 - minor assembly fix in x86 features detection (don't use the PIC
829 register, to avoid relocations in the text segment at runtime)
830 - POSIX callback functions of Thread.h are hidden
831
832 * MIDI driver:
833 - dispatch bank select (MSB and LSB) messages
834
835 * audio driver:
836 - the ALSA audio output driver parameters now reflect the correct
837 parameter value ranges for the respective selected sound card
838 (patch by Till Wimmer, a bit fixed and extended)
839
840 * Gigasampler format engine:
841 - if a filter is used and EG2 finishes before EG1, let the voice
842 die when EG2 has finished (this fixes a problem with clicks and
843 voice starvation for some gigs)
844 - playback is no longer disabled during instrument loading
845 - all notes playing on a channel that changes its instrument keep
846 playing with the old instrument until they get a note off
847 command
848 - EG fix: a release value of zero could cause noises or crash
849 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
850 - EG fine tuning: when attack is zero the EG starts at a level
851 above max sustain level, which means that there is a decay phase
852 even if sustain is 100%
853 - more EG fixes: the level could sometimes go below zero and cause
854 noises or crashes
855 - minor fix of EGDecay (patch by Toshi Nagata)
856 - fixed compiler error when --enable-override-filter-type was
857 supplied to the configure script (fixes #46)
858 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
859 instead of a fix value
860 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
861 127 (solo mode) only kill voices if the respective mode really
862 changed
863
864 * LSCP server:
865 - fixed compile time error for old Bison versions
866 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
867 - parser now supports extended ASCII character set
868 (up to ASCII code 255, i.e. includes now umlauts and accents)
869 - filename arguments in LSCP commands now allow to use escape
870 sequences, that is directly literal as one of: \', \", \\, \n, \r,
871 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
872 code value like \xf2) (fixes bug #24)
873 - the following LSCP commands now also support escape sequences for at
874 least one of their text-based parameters (i.e. name, description):
875 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
876 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
877 "SET DB_INSTRUMENT_DIRECTORY NAME",
878 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
879 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
880 "FIND DB_INSTRUMENT_DIRECTORIES"
881 - returns verbose syntax errors (line and column where syntax error
882 occured, the unexpected character and the actually expected, possible
883 character(s), the latter only if less than 5 possibilities)
884 - made sure that LSCP syntax is not affected by gigedit locale
885 settings
886 - bugfix regarding strings parameter lists: all comma separated lists
887 of strings were treated as being one string containing commas
888 (fixes #57)
889
890 * Bug fixes:
891 - fixed crash occurring on certain LSCP scripts (Bug 39)
892 - another thread safety fix for lscp "load engine" and "set
893 channel audio output device"
894 - fixed a crash which occurs when reassigning the same engine
895 on a sampler channel with connected MIDI device
896 - fixed a crash which occurs when changing the number of ports of a MIDI
897 device connected to a sampler channel to number less then or equal
898 to the index of the port to which the sampler channel is connected.
899 - The previous bindings were not been disconnected when altering
900 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
901 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
902 - The active stream/voice count statistic was incorrect.
903 - notification events were not been sent for some sampler
904 channel changes
905 - added default min and max values to restrict the number of allowed
906 audio output channels and MIDI input ports
907 - the connection to the PCM interface is now closed when destroying
908 an audio output device
909 - files with slash in their path or filename could not be loaded
910
911 * test cases:
912 - updated and fixed (haven't been touched in a while)
913
914 Version 0.4.0 (24 November 2006)
915
916 * packaging changes:
917 - changed deprecated copyright attribute to license; added ldconfig
918 to post-(un)install steps; added devel package for liblinuxsampler;
919 to linuxsampler.spec (RPM)
920 - install necessary development header files for allowing 3rd party
921 applications to link against liblinuxsampler
922 - liblinuxsampler's API documentation can be generated with 'make docs'
923 (Doxygen required)
924 - added benchmark to automatically detect the best triangle LFO
925 implementation (currently either an integer math solution or a
926 di-harmonic approximation), automatic detection can be overriden
927 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
928 configure script argument though (mandatory for cross-compilation)
929 - do not automatically pick optimized gcc flags if the user already
930 provided some on his own (as CXXFLAGS)
931 - added compile time option to disable processing of All-Notes-Off MIDI
932 messages
933 - added compile time options to allow disabling the various audio and
934 MIDI drivers
935 - fixed automatic GCC CPU switch detection on PPC
936 (patch by Ebrahim Mayat)
937
938 * Gigasampler format engine:
939 - extensive synthesis optimization
940 (reimplementation of EGs and LFO(s), removed synthesis parameter
941 prerendering and the synthesis parameter matrix in general, splitting
942 each audio fragment into subfragments now where each subfragment uses
943 constant pitch and filter coefficients. The volume coefficient is
944 linearly interpolated inside a subfragment, unless
945 --disable-interpolate-volume is set.)
946 - fine tuning of the EG modulation parameters
947 - improved filter cutoff calculation by adding support for the
948 following gig parameters: Cutoff freq (used when no cutoff
949 controller is defined), Control invert, Minimum cutoff, Velocity
950 curve and Velocity range. The keyboard tracking now scales
951 cutoff frequency instead of resonance.
952 - added support for gig parameter Resonance.
953 - fixed bug in sysex handling (patch by Juan Linietsky)
954 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
955 which can be overridden with --enable-global-attenuation
956 - EG fixes: made the length of "attack hold" stage more
957 accurate. Release stage can now start before attack stage
958 ends. Cancel release didn't work when sustain was zero. Attack
959 time now has a minimal value to prevent clicks.
960 - fixed pitch changes larger than one octave
961 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
962 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
963 all modes can be altered via standard GM messages, that is CC5 for
964 altering portamento time, CC65 for enabling / disabling portamento
965 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
966 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
967 parameter) and crossfade
968 - added support for the "attenuation controller threshold" gig
969 parameter
970 - added smoothing of volume changes caused by control change
971 messages
972 - sample loop parameters are now taken from the DimensionRegion
973 instead of the wave chunk
974 - fixed keyswitching for v3 gigs with a number of keyswitch splits
975 not equal to a power of two
976 - reimplementation of the filter algorithm. The new filter is more
977 accurate and supports all gig filter types, including bandreject
978 and lowpass turbo.
979 - real support for 24 bit samples - samples are not truncated to
980 16 bits anymore
981 - support for aftertouch (channel pressure, not polyphonic
982 aftertouch)
983 - LFO1 behaviour fixed (dampening from max volume instead of
984 amplifying from 0)
985
986 * LSCP server:
987 - fixed application exit on broken pipe error (fixes bug #20)
988 - fixed the notification messages delay due to lack of
989 network activity (fixes bug #26)
990 - fixed parser bug which occured on space(s) within device parameters
991 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
992
993 * audio driver:
994 - added aRts audio output driver (by no means RT safe)
995
996 * MIDI driver:
997 - fixed legacy sysex code which caused dispatching of MIDI SysEx
998 messages several times instead of once
999 - API extension for MIDI drivers which already supply exact time stamps
1000 for events (i.e. for offline rendering based MIDI drivers)
1001 - added checks for bad MIDI data
1002
1003 * linuxsampler application:
1004 - show available sampler engine types on startup
1005
1006 * general changes:
1007 - support for muting sampler channels and solo mode of the same, two new
1008 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1009 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1010 introduced for this, the behavior is the same like on a mixer console
1011 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1012 --enable-process-muted-channels which can be used to enable the
1013 processing of muted channels.
1014 - support for sostenuto pedal
1015 - support for monitoring the total number of active voices
1016 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1017 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1018 - fixed some memory management errors
1019 - fixed some concurrency problems that could lead to crashes when
1020 LSCP commands were executed
1021 - fixed crash when instrument loading failed previously on the same
1022 sampler channel (fixes bug #36)
1023
1024 Version 0.3.3 (15 July 2005)
1025
1026 * packaging changes:
1027 - fixed compilation with gcc 4.0
1028
1029 * Gigasampler format engine:
1030 - LFO preprocessing was performed even though the respective LFO was
1031 disabled by the instrument patch (minor efficiency fix)
1032 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1033 for volume ramp downs in the same fragment (needed for current voice
1034 stealing implementation) then simply inform the user with a warning
1035 about possible click sounds and reduce the volume ramp down
1036 appropriately instead of cancelling the audio device connection
1037
1038 Version 0.3.2 (24 June 2005)
1039
1040 * packaging changes:
1041 - updated autotools build files to compile on OS X
1042 (conditional compilation of CoreMIDI and MidiShare drivers)
1043 - hand-crafted assembly optimization code can be disabled with
1044 './configure --disable-asm' (definitely not recommended)
1045 - fixed 'make dist' rule to include all necessary files
1046 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1047 (due to 'dist-bzip2' automake option)
1048
1049 * Gigasampler format engine:
1050 - support for the gig parameters for "release velocity response" curves
1051 - fine tuning of the EGADSR envelope
1052 - volume of release triggered samples now depends on note-on velocity,
1053 note length and gig parameter "release trigger decay" instead of
1054 note-off velocity.
1055 - revised voice stealing
1056 (fixes crash and endless loop caused by voice stealing)
1057 - don't reset scale tuning on instrument or audio output device change
1058 - handle key group conflicts right at the beginning of each fragment
1059 instead of when the respective voice is actually launched
1060 (fixes undefined behavior if stolen voices belonged to a key group -
1061 this case was followed by a "killed voice survived" error message)
1062 - fixed minor issue with null/silence samples
1063 (those stole voices even though they don't need a voice at all which
1064 resulted in "voice stealing didn't work out" messages)
1065 - don't reset volume, pan, pitch and MIDI controller values on
1066 instrument or audio output device change
1067
1068 * LSCP server:
1069 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1070 - fixed LSCP event "CHANNEL_INFO" notification
1071 (e.g. did not notify on volume changes or MIDI program change events)
1072
1073 * linuxsampler application:
1074 - added command line parameters --lscp-addr and --lscp-port to override
1075 default IP address and port of LSCP server
1076
1077 Version 0.3.1 (24 May 2005)
1078
1079 * initial release
