* sfz engine: fixed crash when using lochan/hichan opcodes (#187)

1 schoenebeck 1993 Version CVS HEAD (?)
2    
3 capela 2174 * plugin changes:
4 schoenebeck 2304 - LV2 "state" extension support (patch by David Robillard)
5 capela 2174
6 persson 2086 * packaging changes:
7     - fixed building with newer MinGW-w64
8 persson 2183 - Mac OS X: support the new dir for Core Audio SDK
9     - Mac OS X: fixed building outside source directory
10     - made sure all source files for hostplugins are included when
11     doing "make dist"
12     - removed empty directories left from the cvs to svn migration
13 persson 2185 - fixed compilation with gcc 4.6.1
14 persson 2203 - another "make dist" fix, for the LV2 plugin
15 persson 2185 - made --enable-pthread-testcancel default on Mac OS X
16 persson 2197 - minor Makefile fix for building lscpparser when build and source
17     directories are separate
18 persson 2203 - Mac OS X: made it possible to specify plugin installation dir to
19     configure
20 persson 2208 - Mac OS X: Makefile fix for the install-strip target
21 persson 2335 - fixed compilation with gcc 4.7
22 persson 2343 - fixed configure script error with old autoconf versions
23     - lsatomic.h: use gcc provided atomic functions if building with
24     gcc 4.7 and C++11
25 persson 2086
26     * general changes:
27 iliev 2012 - Refactoring: moved the independent code from
28     the Gigasampler format engine to base classes
29 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
30     respective profiling code is currently broken
31 schoenebeck 2053 - Introduced support for optional environment variable
32     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
33     where the sampler shall look for instrument editor plugins
34     (patch by Luis Garrido, slightly modified).
35 schoenebeck 2121 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
36     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
37     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
38     note (in this implementation of the sampler its simply hard routed to
39     the 1st effect send of the sampler channel, no matter what the actual
40     effect type is)
41     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
42     note (in this implementation of the sampler its simply hard routed to
43     the 2nd effect send of the sampler channel, no matter what the actual
44     effect type is)
45 schoenebeck 2124 - implemented support for internal LADSPA effects
46 schoenebeck 2140 - raised limit of program change queue from 100 to 512
47     (as suggested by Alex Stone)
48 iliev 2223 - implemented sine LFO, pulse LFO and saw LFO
49 iliev 2296 - experimental support for per voice equalization
50 iliev 2306 - added command line option --exec-after-init
51 schoenebeck 2330 - Introduced new C++ API method:
52     EngineChannel::InstrumentFileName(int index)
53     allowing to retrieve the whole list of files used for the loaded
54     instrument on an engine channel (a.k.a. part). Some GigaStudio
55     instruments for example are splitted over several files like
56     "Foo.gig", "Foo.gx01", "Foo.gx02", ...
57 iliev 2012
58 persson 2043 * Gigasampler format engine:

335 schoenebeck 2275 - When creating MIDI instrument map entries with "PERSISTENT" type, the
336     instruments were uselessly precached with zero samples, however it still
337     took the full preloading time and on 1st program change the respective
338     instrument was completely reloaded again.
339 persson 2277 - fixed handling of rapid bank select and program change messages
340     sent to the same sampler channel (patch from the Open Octave
341     project, slightly adjusted)

359 schoenebeck 1599
360 schoenebeck 1639 * packaging changes:
361     - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

388     unnecessarily long after an update
389 schoenebeck 1653 - added support for notifying instrument editors on note-on / note-off
390     events (e.g. to highlight the pressed keys on the virtual keyboard

404 schoenebeck 1800 - maximum voices and disk streams can now be altered at runtime
405 persson 1825 - fixed CPU feature detection on x86_64 (maybe fixes #108)
406 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
407     be switched on by command line option "--stacktrace" (the automatic
408     stacktrace mechanism seems to be broken on most systems at the moment)
409 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
410     a pointer to the launched InstrumentEditor object
411 schoenebeck 1876 - added optional 3rd party user data parameter for following
412     liblinuxsampler C++ API methods: InstrumentEditor::Main(),

422 schoenebeck 1599 * audio driver:
423     - removed the nonsense audio channel constraint (which was hard coded to
424     max. 100 audio channels) for most audio drivers
425 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
426     opposed to the LSCP specs
427 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
428     reflected the wrong value
429 persson 1644 - fixed a memory management bug in ASIO driver
430 persson 1748 - Makefile fix: JACK_CFLAGS wasn't used

432 persson 1748 jack_client_new
433 iliev 1829 - added (experimental) CoreAudio driver
434 persson 1888 - applied old fixes to the ASIO driver that were included in the
435     previous binary release but accidentally never committed to CVS
436     (fixes #117)
437 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
438     win64)
439 persson 1895 - VST: added support for sample rate and buffer size changes
440     - VST: close editor (Fantasia) when the VST is removed

447     stored in the plugin state
448 schoenebeck 1930 - performance optimization of AudioChannel::MixTo() and
449     AudioChannel::CopyTo() methods using GCC vector exensions
450     (if available)
451 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
452     exception when getting parameters from a disconnected device
453 schoenebeck 1599
454 persson 1651 * MIDI driver:
455     - added JACK MIDI driver
456 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
457     want to (mis)use it for some purpose ("fixed" in all current MIDI
458     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
459 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
460 persson 1887 CoreMidi or AU
461 persson 1889 - fixed mingw-w64 compilation error in MME driver
462 persson 1924 - made program change handling in MIDI thread real-time safe by
463     moving the logic to a non-RT thread

468     to the instruments database
469 iliev 1727 - added support for handling lost files in the instruments database
470 iliev 1781 - Implemented option for adding instruments in separate directories
471     in the instruments database
472     (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
473 persson 1908 - work-around for missing fnmatch function on Windows to make
474     instrument database compilable
475 schoenebeck 1930 - added instrument database support on Windows
476     works with both standalone mode and VST plugin.
477     the instruments DB file is located in
478     %USERPROFILE%\.linuxsampler\instruments.db which allows different
479     databases for each windows user
480     if no DB is present it automatically creates the .linuxsampler subdir
481     and then creates an empty DB
482 persson 1943 - fixed recursive import, which was broken on Windows
483 iliev 1603
484 persson 1644 * Gigasampler format engine:
485     - fixed a memory leak that could happen when a channel was deleted
486     while notes were playing
487 persson 1646 - made it possible to load an instrument even if the audio thread
488     isn't running
489 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
490     enough for piano gigs with pedal noise samples
491 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
492     respective FX send MIDI controller was used
493 schoenebeck 1724 - added support for GM global device volume SysEx message
494 schoenebeck 1762 (can be selected at compile time to either apply globally to the
495     whole sampler [default] or only to the sampler channels that are
496     connected to the respective MIDI input port the SysEx message arrived
497     on)
498 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
499     sometimes wrongly killed in the same buffer, causing no sound to
500     be played
501 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
502     which is usally used to switch a part between chromatic sounds and
503     drumkit sounds (as opposed to their common default setting of MIDI
504     part 10 being a drumkit part and all other ones chromatic parts), in
505     LS however one can switch between the first 16 MIDI instrument maps
506     defined for the sampler
507 persson 1764 - made it possible to create multiple sample channels even if the
508     audio thread isn't running
509 persson 1844 - fixed crash when removing channel with active voices (#116)
510 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
511     un-cache the respective sample if it's really not used by any
512     sampler engine anymore
513     - re-cache samples in case they were changed by an instrument editor,
514     e.g. when a sample was added while playing (#82)
515 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
516     same time stamp as the voice's note-on event and occured both in the
517     same audio fragment cycle (fixes bug #112)
518 persson 1858 - added support for the "fine tune" and "pitch bend range"
519     instrument-level gig parameters
520     - fixed minor artifacts in pitch bend handling
521 schoenebeck 1860 - added support for GS Reset SysEx message
522 persson 1862 - allow gig files to use unlimited downward pitch shifting
523     - added a limit check for upward pitch shifting
524 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
525     note was silent
526 persson 1923 - fixed crash happening when a pitch bend event arrived at the
527     same time a new instrument was loading
528 persson 1644
529 schoenebeck 1687 * LSCP server:
530     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
531     react on MIDI data arriving on certain sampler channels (so far only
532     Note-On and Note-Off events are sent via this LSCP event)
533 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
534     react on MIDI data arriving on certain MIDI input devices (so far only
535     Note-On and Note-Off events are sent via this LSCP event)
536 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
537     SET DB_INSTRUMENT FILE_PATH
538 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
539     frontends to send MIDI messages to specific sampler channel
540     - added two additional fields to GET FILE INSTRUMENT INFO command -
541     KEY_BINDINGS and KEYSWITCH_BINDINGS
542 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
543     was incorrect
544 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
545 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
546     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
547     be triggered respectively
548     - added new LSCP command "SET STREAMS" to globally alter the maximum
549     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
550     which will be triggered respectively
551 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
552     a gigedit file dialog is opened)
553 iliev 1848 - close all connections when LSCPServer is deleted
554 iliev 1882 - hard close of all sockets on exit
555 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
556     driver
557 schoenebeck 1687
558 iliev 1761 * Bug fixes:
559     - fixed a crash which occurs when removing a sampler channel waiting
560     to start instrument loading after another channel
561 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
562     instrument loading in progress (bug #113)
563 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
564     instrument with PERSISTENT load mode
565 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
566     - fixed memory leaks when issuing the following LSCP commands:
567     GET AUDIO_OUTPUT_DRIVER INFO
568     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
569     GET MIDI_INPUT_DRIVER INFO
570     GET MIDI_INPUT_DRIVER_PARAMETER INFO
571     - fixed possible compilation error when sqlite is not present
572 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
573 iliev 1847 - fixed crash when changing the audio output device of a sampler
574     channel with loaded instrument and start playing notes
575 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
576 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
577     PowerPC, which probably could cause crashes on that platform
578 persson 1889 - fixed a memory management error which could cause a crash when a
579     plugin was unloaded
580 persson 1896 - bugfix: two private structs had the same name, which could cause
581     problems if the linker chose the wrong constructor
582 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
583     Windows
584 iliev 1761
585    
586 schoenebeck 1560 Version 0.5.1 (6 December 2007)
587 schoenebeck 1454
588     * packaging changes:
589     - added autoconf checks for pthread library
590     - added autoconf check for pthread bug found on certain NPTL-enabled
591     glibc versions (see Gentoo bug report #194076)
592 senoner 1502 - added autoconf checks for MS Windows
593 schoenebeck 1454
594 persson 1455 * general changes:
595     - bugfix: the thread used by an editor plugin didn't die when the
596     editor closed
597 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
598     out all the space. operator--() did not apply size_mask after
599     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
600     order to avoid problems with the _NonVolatileReader functions.
601     - bugfix: Stream.h: added a missing divide by BytesPerSample in
602     GetWriteSpace(). Since this function is currently only used in
603     the stream's qsort() compare function, it didn't trigger any
604     bugs.
605     - Resampler.h, Synthesizer.h: cubic interpolation now works in
606     24bit mode too. Faster method to read 24bit words on little
607     endian machines (x86): replaced 3 byte reads + shifts with a 1
608     unaligned 32bit read and shift
609     - experimental support for MS Windows (MIDI input via MME, AUDIO
610     output via ASIO)
611     - made handling of SIGINT signal (Ctrl-C) a bit more robust
612 iliev 1541 - support for monitoring the total number of active disk streams
613     (new LSCP commands: GET TOTAL_STREAM_COUNT,
614     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
615 persson 1455
616 senoner 1500 * AUDIO driver:
617 persson 1534 - added Windows ASIO low latency audio driver
618 senoner 1500
619 senoner 1485 * MIDI driver:
620 schoenebeck 1495 - added MME Windows MIDI driver
621 senoner 1485
622 schoenebeck 1471 * LSCP server:
623     - added support for Windows style path / filenames, however with
624     forward slash path separators instead of backslash
625     (i.e. "C:/foo/bar.gig")
626 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
627     apostrophes as well
628 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
629     "LIST FILE INSTRUMENTS <file>" and
630     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
631     about an arbitrary instrument file on the system where the sampler is
632     running on
633 schoenebeck 1471
634 schoenebeck 1424 Version 0.5.0 (15 October 2007)
635 schoenebeck 947
636 schoenebeck 1065 * packaging changes:
637 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
638     API header files anymore
639 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
640     the Doxygen API documentation (explicitly listed in Doxyfile.in)
641 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
642     capable to execute our autoconf environment, thus no need anymore
643     to maintain the compile time configuration file (osx/version.h) for
644     OSX manually (patch by Toshi Nagata)
645 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
646     parameters
647 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
648     C++ API header files, all implementation internal global definitions
649     are now in global_private.h
650     - atomic.h is not exposed to the C++ API anymore
651     - no need to include config.h anymore for using LS's API header files
652     - fixed warnings in API doc generation
653 schoenebeck 1065
654 schoenebeck 947 * general changes:
655     - replaced the old, confusing MIDI program change mechanism by a
656     flexible MIDI instrument mapper which allows to map arbitrary
657 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
658 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
659     loaded on the respective channel when such MIDI program change
660     messages arrive, beside that, each entry allows to define a life-time
661     strategy for the instrument, so the user can define whether the
662     instrument should i.e. be permanently loaded (to be able to switch
663     quickly among sounds) or i.e. loaded just on demand when the
664     respective program change arrives (to safe RAM space), as well as a
665     global volume factor for each entry, so the user can adjust the volume
666     dynamic of his mapped instrument collection without having to modify
667 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
668     MIDI instrument maps and assign each sampler channel individually
669     a certain map, so that i.e. separation of normal instruments and
670     drumkits is possible
671 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
672     MIDI instrument maps, MIDI instruments, FX sends, global volume.
673 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
674     due to a constant size RingBuffer FIFO which is now replaced by a
675     dynamic (unlimited) size std::list FIFO
676 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
677     output channels for being processed by external effect processors
678     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
679     controllers
680 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
681 iliev 1130 - Implemented new, improved notification system
682 schoenebeck 1149 - fixed compilation errors regarding OSX
683     (patch by Toshi Nagata)
684 iliev 1161 - implemented instruments database
685 iliev 1345 - added support for escape sequences to the instruments database
686 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
687     within the sampler's process (by using instrument editor plugins),
688     you'll notice the new "Registered instrument editors:" message on
689 schoenebeck 1407 startup, added a new LSCP command:
690     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
691 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
692     given sampler channel, the plugin path can be overridden at compile
693     time with ./configure --enable-plugin-dir=/some/dir
694 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
695     in the sampler's process to safely edit instruments while playing
696     without a crash (hopefully) by either suspending single regions
697     wherever possible or if unavoidable whole engine(s)
698 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
699     policy and priority on thread level, set a minimum stack size for
700     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
701     threads simply inherited properties of starting thread instead of
702     setting their own policy and priority
703 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
704     main process did not wait for the stack trace process to finish
705     its output
706 persson 1248 - fixed some minor memory leaks
707 schoenebeck 1259 - reenabled assembly features support, at the moment only for
708     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
709 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
710     register, to avoid relocations in the text segment at runtime)
711 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
712 schoenebeck 947
713     * MIDI driver:
714     - dispatch bank select (MSB and LSB) messages
715    
716 schoenebeck 1049 * audio driver:
717     - the ALSA audio output driver parameters now reflect the correct
718     parameter value ranges for the respective selected sound card
719     (patch by Till Wimmer, a bit fixed and extended)
720    
721 persson 951 * Gigasampler format engine:
722     - if a filter is used and EG2 finishes before EG1, let the voice
723     die when EG2 has finished (this fixes a problem with clicks and
724     voice starvation for some gigs)
725 persson 1038 - playback is no longer disabled during instrument loading
726     - all notes playing on a channel that changes its instrument keep
727     playing with the old instrument until they get a note off
728     command
729 persson 1039 - EG fix: a release value of zero could cause noises or crash
730 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
731 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
732     above max sustain level, which means that there is a decay phase
733     even if sustain is 100%
734 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
735     noises or crashes
736 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
737 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
738     supplied to the configure script (fixes #46)
739 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
740     instead of a fix value
741 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
742     127 (solo mode) only kill voices if the respective mode really
743     changed
744 persson 951
745 schoenebeck 1244 * LSCP server:
746     - fixed compile time error for old Bison versions
747     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
748 schoenebeck 1245 - parser now supports extended ASCII character set
749     (up to ASCII code 255, i.e. includes now umlauts and accents)
750     - filename arguments in LSCP commands now allow to use escape
751     sequences, that is directly literal as one of: \', \", \\, \n, \r,
752     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
753     code value like \xf2) (fixes bug #24)
754 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
755     least one of their text-based parameters (i.e. name, description):
756     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
757     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
758     "SET DB_INSTRUMENT_DIRECTORY NAME",
759     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
760     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
761     "FIND DB_INSTRUMENT_DIRECTORIES"
762 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
763     occured, the unexpected character and the actually expected, possible
764     character(s), the latter only if less than 5 possibilities)
765 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
766     settings
767 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
768     of strings were treated as being one string containing commas
769     (fixes #57)
770 schoenebeck 1244
771 iliev 959 * Bug fixes:
772     - fixed crash occurring on certain LSCP scripts (Bug 39)
773 persson 1038 - another thread safety fix for lscp "load engine" and "set
774     channel audio output device"
775 iliev 1283 - fixed a crash which occurs when reassigning the same engine
776     on a sampler channel with connected MIDI device
777 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
778     device connected to a sampler channel to number less then or equal
779     to the index of the port to which the sampler channel is connected.
780 iliev 1296 - The previous bindings were not been disconnected when altering
781     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
782     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
783 iliev 1297 - The active stream/voice count statistic was incorrect.
784 iliev 1298 - notification events were not been sent for some sampler
785     channel changes
786 iliev 1305 - added default min and max values to restrict the number of allowed
787     audio output channels and MIDI input ports
788 iliev 1306 - the connection to the PCM interface is now closed when destroying
789     an audio output device
790 schoenebeck 1332 - files with slash in their path or filename could not be loaded
791 iliev 959
792 schoenebeck 1221 * test cases:
793     - updated and fixed (haven't been touched in a while)
794    
795 schoenebeck 937 Version 0.4.0 (24 November 2006)
796 persson 696
797 schoenebeck 697 * packaging changes:
798 capela 868 - changed deprecated copyright attribute to license; added ldconfig
799     to post-(un)install steps; added devel package for liblinuxsampler;
800     to linuxsampler.spec (RPM)
801 schoenebeck 697 - install necessary development header files for allowing 3rd party
802     applications to link against liblinuxsampler
803     - liblinuxsampler's API documentation can be generated with 'make docs'
804     (Doxygen required)
805 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
806     implementation (currently either an integer math solution or a
807     di-harmonic approximation), automatic detection can be overriden
808     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
809     configure script argument though (mandatory for cross-compilation)
810 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
811     provided some on his own (as CXXFLAGS)
812 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
813     messages
814 schoenebeck 852 - added compile time options to allow disabling the various audio and
815     MIDI drivers
816 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
817     (patch by Ebrahim Mayat)
818 schoenebeck 697
819 persson 696 * Gigasampler format engine:
820 schoenebeck 738 - extensive synthesis optimization
821     (reimplementation of EGs and LFO(s), removed synthesis parameter
822     prerendering and the synthesis parameter matrix in general, splitting
823     each audio fragment into subfragments now where each subfragment uses
824 persson 830 constant pitch and filter coefficients. The volume coefficient is
825     linearly interpolated inside a subfragment, unless
826     --disable-interpolate-volume is set.)
827 persson 696 - fine tuning of the EG modulation parameters
828 persson 729 - improved filter cutoff calculation by adding support for the
829     following gig parameters: Cutoff freq (used when no cutoff
830     controller is defined), Control invert, Minimum cutoff, Velocity
831 persson 791 curve and Velocity range. The keyboard tracking now scales
832     cutoff frequency instead of resonance.
833 persson 877 - added support for gig parameter Resonance.
834 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
835 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
836     which can be overridden with --enable-global-attenuation
837 persson 783 - EG fixes: made the length of "attack hold" stage more
838     accurate. Release stage can now start before attack stage
839 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
840     time now has a minimal value to prevent clicks.
841 persson 799 - fixed pitch changes larger than one octave
842 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
843     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
844     all modes can be altered via standard GM messages, that is CC5 for
845     altering portamento time, CC65 for enabling / disabling portamento
846     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
847 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
848     parameter) and crossfade
849 persson 831 - added support for the "attenuation controller threshold" gig
850     parameter
851 persson 832 - added smoothing of volume changes caused by control change
852     messages
853 persson 865 - sample loop parameters are now taken from the DimensionRegion
854     instead of the wave chunk
855     - fixed keyswitching for v3 gigs with a number of keyswitch splits
856     not equal to a power of two
857 persson 877 - reimplementation of the filter algorithm. The new filter is more
858     accurate and supports all gig filter types, including bandreject
859     and lowpass turbo.
860 persson 903 - real support for 24 bit samples - samples are not truncated to
861     16 bits anymore
862     - support for aftertouch (channel pressure, not polyphonic
863     aftertouch)
864 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
865     amplifying from 0)
866 persson 696
867 schoenebeck 711 * LSCP server:
868     - fixed application exit on broken pipe error (fixes bug #20)
869 iliev 793 - fixed the notification messages delay due to lack of
870     network activity (fixes bug #26)
871 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
872     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
873 schoenebeck 711
874 schoenebeck 838 * audio driver:
875     - added aRts audio output driver (by no means RT safe)
876    
877 schoenebeck 775 * MIDI driver:
878     - fixed legacy sysex code which caused dispatching of MIDI SysEx
879     messages several times instead of once
880 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
881     for events (i.e. for offline rendering based MIDI drivers)
882 persson 922 - added checks for bad MIDI data
883 schoenebeck 775
884 schoenebeck 900 * linuxsampler application:
885     - show available sampler engine types on startup
886    
887 schoenebeck 705 * general changes:
888     - support for muting sampler channels and solo mode of the same, two new
889     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
890     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
891     introduced for this, the behavior is the same like on a mixer console
892 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
893     --enable-process-muted-channels which can be used to enable the
894     processing of muted channels.
895 iliev 777 - support for sostenuto pedal
896 iliev 779 - support for monitoring the total number of active voices
897 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
898     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
899 persson 835 - fixed some memory management errors
900 persson 841 - fixed some concurrency problems that could lead to crashes when
901     LSCP commands were executed
902 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
903     sampler channel (fixes bug #36)
904 schoenebeck 705
905 schoenebeck 692 Version 0.3.3 (15 July 2005)
906 schoenebeck 686
907     * packaging changes:
908     - fixed compilation with gcc 4.0
909    
910 schoenebeck 687 * Gigasampler format engine:
911     - LFO preprocessing was performed even though the respective LFO was
912     disabled by the instrument patch (minor efficiency fix)
913 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
914     for volume ramp downs in the same fragment (needed for current voice
915     stealing implementation) then simply inform the user with a warning
916     about possible click sounds and reduce the volume ramp down
917     appropriately instead of cancelling the audio device connection
918 schoenebeck 687
919 schoenebeck 677 Version 0.3.2 (24 June 2005)
920 schoenebeck 609
921     * packaging changes:
922     - updated autotools build files to compile on OS X
923     (conditional compilation of CoreMIDI and MidiShare drivers)
924 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
925     './configure --disable-asm' (definitely not recommended)
926 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
927     - require automake (>= 1.5) for 'make -f Makefile.cvs'
928     (due to 'dist-bzip2' automake option)
929 schoenebeck 649
930     * Gigasampler format engine:
931     - support for the gig parameters for "release velocity response" curves
932     - fine tuning of the EGADSR envelope
933     - volume of release triggered samples now depends on note-on velocity,
934     note length and gig parameter "release trigger decay" instead of
935     note-off velocity.
936 schoenebeck 663 - revised voice stealing
937     (fixes crash and endless loop caused by voice stealing)
938 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
939 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
940     instead of when the respective voice is actually launched
941     (fixes undefined behavior if stolen voices belonged to a key group -
942     this case was followed by a "killed voice survived" error message)
943 schoenebeck 669 - fixed minor issue with null/silence samples
944     (those stole voices even though they don't need a voice at all which
945     resulted in "voice stealing didn't work out" messages)
946 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
947     instrument or audio output device change
948 schoenebeck 654
949 schoenebeck 620 * LSCP server:
950 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
951 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
952 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
953 schoenebeck 609
954 schoenebeck 668 * linuxsampler application:
955     - added command line parameters --lscp-addr and --lscp-port to override
956     default IP address and port of LSCP server
957    
958 schoenebeck 579 Version 0.3.1 (24 May 2005)
959    
960     * initial release
