* modernized configure script

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

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

25 persson 2365 - modernized configure script
26    
27 persson 2086 * general changes:
28 iliev 2012 - Refactoring: moved the independent code from
29     the Gigasampler format engine to base classes
30 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
31     respective profiling code is currently broken
32 schoenebeck 2053 - Introduced support for optional environment variable
33     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
34     where the sampler shall look for instrument editor plugins
35     (patch by Luis Garrido, slightly modified).
36 schoenebeck 2121 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
37     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
38     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
39     note (in this implementation of the sampler its simply hard routed to
40     the 1st effect send of the sampler channel, no matter what the actual
41     effect type is)
42     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
43     note (in this implementation of the sampler its simply hard routed to
44     the 2nd effect send of the sampler channel, no matter what the actual
45     effect type is)
46 schoenebeck 2124 - implemented support for internal LADSPA effects
47 schoenebeck 2140 - raised limit of program change queue from 100 to 512
48     (as suggested by Alex Stone)

51 iliev 2306 - added command line option --exec-after-init
52 schoenebeck 2330 - Introduced new C++ API method:
53     EngineChannel::InstrumentFileName(int index)
54     allowing to retrieve the whole list of files used for the loaded
55     instrument on an engine channel (a.k.a. part). Some GigaStudio
56     instruments for example are splitted over several files like
57     "Foo.gig", "Foo.gx01", "Foo.gx02", ...
58 iliev 2012
59 persson 2043 * Gigasampler format engine:

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

360 schoenebeck 1599
361 schoenebeck 1639 * packaging changes:
362     - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
363     causing e.g. the libgig test to fail when
364     "./configure --disable-jack-driver" was used
365     (patch by Alexis Ballier)

380 schoenebeck 1639
381 schoenebeck 1601 * general changes:

385 schoenebeck 1602 - fixed endless loop which occured when loading an instrument editor
386     plugin DLL on Windows systems failed
387 persson 1644 - fixed memory leaks that occurred when liblinuxsampler was unloaded

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

394 schoenebeck 1653 - be verbose on DLL load errors (on Linux)
395 schoenebeck 1681 - fixed di-harmonic triangle LFO implementation (this LFO implementation

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

422 schoenebeck 1601
423 schoenebeck 1599 * audio driver:
424     - removed the nonsense audio channel constraint (which was hard coded to
425     max. 100 audio channels) for most audio drivers
426 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
427     opposed to the LSCP specs
428 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
429     reflected the wrong value
430 persson 1644 - fixed a memory management bug in ASIO driver
431 persson 1748 - Makefile fix: JACK_CFLAGS wasn't used
432 persson 1777 - JACK: use jack_client_open instead of the deprecated
433 persson 1748 jack_client_new
434 iliev 1829 - added (experimental) CoreAudio driver
435 persson 1888 - applied old fixes to the ASIO driver that were included in the
436     previous binary release but accidentally never committed to CVS
437     (fixes #117)
438 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
439     win64)
440 persson 1895 - VST: added support for sample rate and buffer size changes
441     - VST: close editor (Fantasia) when the VST is removed

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

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