File size: 48637 byte(s)
* Introduced new C++ API method EngineChannel::InstrumentFileName(int index)
  allowing to retrieve the whole list of files used for the loaded
  instrument on an engine channel (a.k.a. part). Some GigaStudio instruments
  for example are splitted over several files like "Foo.gig", "Foo.gx01",
  "Foo.gx02", ...
* Bumped version to 1.0.0.svn18

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 2086
22     * general changes:
23 iliev 2012 - Refactoring: moved the independent code from
24     the Gigasampler format engine to base classes
25 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
26     respective profiling code is currently broken
27 schoenebeck 2053 - Introduced support for optional environment variable
28     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
29     where the sampler shall look for instrument editor plugins
30     (patch by Luis Garrido, slightly modified).

32     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
33     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
34     note (in this implementation of the sampler its simply hard routed to
35     the 1st effect send of the sampler channel, no matter what the actual
36     effect type is)
37     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
38     note (in this implementation of the sampler its simply hard routed to
39     the 2nd effect send of the sampler channel, no matter what the actual
40     effect type is)

336 schoenebeck 1599
337 schoenebeck 1639 * packaging changes:
338     - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
339     causing e.g. the libgig test to fail when
340     "./configure --disable-jack-driver" was used
341     (patch by Alexis Ballier)
342 persson 1713 - fixed compilation with gcc 4.3

349 persson 1897 - Windows: look for editor plugins and Fantasia using base
350 schoenebeck 1928 directory of liblinuxsampler dll (look in the same directory and one
351     directory above)
352 persson 1899 - configure script fix: removed unconditional use of SSE
353 persson 1923 - fixed building with sqlite installed in a non-standard directory
354 persson 1931 - when cross-compiling, don't try to create instruments.db
355     - fix for new mingw-w64 version, which has usleep
356 schoenebeck 1639
357 schoenebeck 1601 * general changes:
358     - bugfix: on some POSIX systems instrument editor plugins refused to
359     load as we used a non-portable Linux specific struct field
360     (fixes bug #70, patch by Ronald Baljeu)
361 schoenebeck 1602 - fixed endless loop which occured when loading an instrument editor
362     plugin DLL on Windows systems failed
363 persson 1644 - fixed memory leaks that occurred when liblinuxsampler was unloaded
364     - optimized the SynchronizedConfig class so it doesn't wait
365     unnecessarily long after an update
366 schoenebeck 1653 - added support for notifying instrument editors on note-on / note-off
367     events (e.g. to highlight the pressed keys on the virtual keyboard
368     of gigedit)
369 schoenebeck 1659 - added support for triggering notes by instrument editors (see above)
370 schoenebeck 1653 - be verbose on DLL load errors (on Linux)
371 schoenebeck 1681 - fixed di-harmonic triangle LFO implementation (this LFO implementation
372     is only used by very few systems, most pick the int math
373     implementation, which is usually faster)
374 persson 1748 - fixes for audio drivers with varying buffer sizes
375 persson 1777 - experimental support for running LinuxSampler as a DSSI, LV2 and
376     VST plugin
377 iliev 1789 - notification events for stream/voice count statistics are now sent
378     only when there are actual changes
379 persson 1790 - added memory ordering constraints to improve stability on
380     multi-core and multi-cpu systems
381 schoenebeck 1800 - maximum voices and disk streams can now be altered at runtime
382 persson 1825 - fixed CPU feature detection on x86_64 (maybe fixes #108)
383 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
384     be switched on by command line option "--stacktrace" (the automatic
385     stacktrace mechanism seems to be broken on most systems at the moment)
386 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
387     a pointer to the launched InstrumentEditor object
388 schoenebeck 1876 - added optional 3rd party user data parameter for following
389     liblinuxsampler C++ API methods: InstrumentEditor::Main(),
390     InstrumentEditor::Launch(),
391     InstrumentManager::LaunchInstrumentEditor()
392 persson 1887 - theoretical fix: made SynchronizedConfig follow C++0x memory
393     model more strictly
394 persson 1895 - fixes for using large audio device buffers
395 persson 1951 - Windows: add the installation directory to the DLL search path
396     when loading an editor plugin (solves problems with VST and
397     gigedit on systems with other GTK versions installed)
398 schoenebeck 1601
399 schoenebeck 1599 * audio driver:
400     - removed the nonsense audio channel constraint (which was hard coded to
401     max. 100 audio channels) for most audio drivers
402 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
403     opposed to the LSCP specs
404 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
405     reflected the wrong value
406 persson 1644 - fixed a memory management bug in ASIO driver
407 persson 1748 - Makefile fix: JACK_CFLAGS wasn't used
408 persson 1777 - JACK: use jack_client_open instead of the deprecated
409 persson 1748 jack_client_new
410 iliev 1829 - added (experimental) CoreAudio driver
411 persson 1888 - applied old fixes to the ASIO driver that were included in the
412     previous binary release but accidentally never committed to CVS
413     (fixes #117)
414 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
415     win64)
416 persson 1895 - VST: added support for sample rate and buffer size changes
417     - VST: close editor (Fantasia) when the VST is removed
418 persson 1908 - VST: avoid opening Fantasia more than once for each VST instance
419     - VST: export main function as "main" on Linux too (fix for
420     energyXT)
421 persson 1917 - VST: changed number of output channels from one stereo to 16
422     stereo
423 persson 1922 - added channel routing, fxsends and midi maps to the settings
424     stored in the plugin state
425 schoenebeck 1930 - performance optimization of AudioChannel::MixTo() and
426     AudioChannel::CopyTo() methods using GCC vector exensions
427     (if available)
428 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
429     exception when getting parameters from a disconnected device
430 schoenebeck 1599
431 persson 1651 * MIDI driver:
432     - added JACK MIDI driver
433 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
434     want to (mis)use it for some purpose ("fixed" in all current MIDI
435     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
436 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
437 persson 1887 CoreMidi or AU
438 persson 1889 - fixed mingw-w64 compilation error in MME driver
439 persson 1924 - made program change handling in MIDI thread real-time safe by
440     moving the logic to a non-RT thread
441 persson 1951 - fixed minor memory leak in ALSA driver
442 persson 1651
443 schoenebeck 1604 * instruments database:
444 iliev 1603 - avoid time consuming samples scanning when adding instruments
445     to the instruments database
446 iliev 1727 - added support for handling lost files in the instruments database
447 iliev 1781 - Implemented option for adding instruments in separate directories
448     in the instruments database
449     (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
450 persson 1908 - work-around for missing fnmatch function on Windows to make
451     instrument database compilable
452 schoenebeck 1930 - added instrument database support on Windows
453     works with both standalone mode and VST plugin.
454     the instruments DB file is located in
455     %USERPROFILE%\.linuxsampler\instruments.db which allows different
456     databases for each windows user
457     if no DB is present it automatically creates the .linuxsampler subdir
458     and then creates an empty DB
459 persson 1943 - fixed recursive import, which was broken on Windows
460 iliev 1603
461 persson 1644 * Gigasampler format engine:
462     - fixed a memory leak that could happen when a channel was deleted
463     while notes were playing
464 persson 1646 - made it possible to load an instrument even if the audio thread
465     isn't running
466 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
467     enough for piano gigs with pedal noise samples
468 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
469     respective FX send MIDI controller was used
470 schoenebeck 1724 - added support for GM global device volume SysEx message
471 schoenebeck 1762 (can be selected at compile time to either apply globally to the
472     whole sampler [default] or only to the sampler channels that are
473     connected to the respective MIDI input port the SysEx message arrived
474     on)
475 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
476     sometimes wrongly killed in the same buffer, causing no sound to
477     be played
478 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
479     which is usally used to switch a part between chromatic sounds and
480     drumkit sounds (as opposed to their common default setting of MIDI
481     part 10 being a drumkit part and all other ones chromatic parts), in
482     LS however one can switch between the first 16 MIDI instrument maps
483     defined for the sampler
484 persson 1764 - made it possible to create multiple sample channels even if the
485     audio thread isn't running
486 persson 1844 - fixed crash when removing channel with active voices (#116)
487 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
488     un-cache the respective sample if it's really not used by any
489     sampler engine anymore
490     - re-cache samples in case they were changed by an instrument editor,
491     e.g. when a sample was added while playing (#82)
492 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
493     same time stamp as the voice's note-on event and occured both in the
494     same audio fragment cycle (fixes bug #112)
495 persson 1858 - added support for the "fine tune" and "pitch bend range"
496     instrument-level gig parameters
497     - fixed minor artifacts in pitch bend handling
498 schoenebeck 1860 - added support for GS Reset SysEx message
499 persson 1862 - allow gig files to use unlimited downward pitch shifting
500     - added a limit check for upward pitch shifting
501 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
502     note was silent
503 persson 1923 - fixed crash happening when a pitch bend event arrived at the
504     same time a new instrument was loading
505 persson 1644
506 schoenebeck 1687 * LSCP server:
507     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
508     react on MIDI data arriving on certain sampler channels (so far only
509     Note-On and Note-Off events are sent via this LSCP event)
510 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
511     react on MIDI data arriving on certain MIDI input devices (so far only
512     Note-On and Note-Off events are sent via this LSCP event)
513 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
514     SET DB_INSTRUMENT FILE_PATH
515 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
516     frontends to send MIDI messages to specific sampler channel
517     - added two additional fields to GET FILE INSTRUMENT INFO command -
518     KEY_BINDINGS and KEYSWITCH_BINDINGS
519 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
520     was incorrect
521 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
522 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
523     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
524     be triggered respectively
525     - added new LSCP command "SET STREAMS" to globally alter the maximum
526     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
527     which will be triggered respectively
528 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
529     a gigedit file dialog is opened)
530 iliev 1848 - close all connections when LSCPServer is deleted
531 iliev 1882 - hard close of all sockets on exit
532 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
533     driver
534 schoenebeck 1687
535 iliev 1761 * Bug fixes:
536     - fixed a crash which occurs when removing a sampler channel waiting
537     to start instrument loading after another channel
538 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
539     instrument loading in progress (bug #113)
540 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
541     instrument with PERSISTENT load mode
542 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
543     - fixed memory leaks when issuing the following LSCP commands:
544     GET AUDIO_OUTPUT_DRIVER INFO
545     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
546     GET MIDI_INPUT_DRIVER INFO
547     GET MIDI_INPUT_DRIVER_PARAMETER INFO
548     - fixed possible compilation error when sqlite is not present
549 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
550 iliev 1847 - fixed crash when changing the audio output device of a sampler
551     channel with loaded instrument and start playing notes
552 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
553 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
554     PowerPC, which probably could cause crashes on that platform
555 persson 1889 - fixed a memory management error which could cause a crash when a
556     plugin was unloaded
557 persson 1896 - bugfix: two private structs had the same name, which could cause
558     problems if the linker chose the wrong constructor
559 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
560     Windows
561 iliev 1761
562    
563 schoenebeck 1560 Version 0.5.1 (6 December 2007)
564 schoenebeck 1454
565     * packaging changes:
566     - added autoconf checks for pthread library
567     - added autoconf check for pthread bug found on certain NPTL-enabled
568     glibc versions (see Gentoo bug report #194076)
569 senoner 1502 - added autoconf checks for MS Windows
570 schoenebeck 1454
571 persson 1455 * general changes:
572     - bugfix: the thread used by an editor plugin didn't die when the
573     editor closed
574 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
575     out all the space. operator--() did not apply size_mask after
576     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
577     order to avoid problems with the _NonVolatileReader functions.
578     - bugfix: Stream.h: added a missing divide by BytesPerSample in
579     GetWriteSpace(). Since this function is currently only used in
580     the stream's qsort() compare function, it didn't trigger any
581     bugs.
582     - Resampler.h, Synthesizer.h: cubic interpolation now works in
583     24bit mode too. Faster method to read 24bit words on little
584     endian machines (x86): replaced 3 byte reads + shifts with a 1
585     unaligned 32bit read and shift
586     - experimental support for MS Windows (MIDI input via MME, AUDIO
587     output via ASIO)
588     - made handling of SIGINT signal (Ctrl-C) a bit more robust
589 iliev 1541 - support for monitoring the total number of active disk streams
590     (new LSCP commands: GET TOTAL_STREAM_COUNT,
591     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
592 persson 1455
593 senoner 1500 * AUDIO driver:
594 persson 1534 - added Windows ASIO low latency audio driver
595 senoner 1500
596 senoner 1485 * MIDI driver:
597 schoenebeck 1495 - added MME Windows MIDI driver
598 senoner 1485
599 schoenebeck 1471 * LSCP server:
600     - added support for Windows style path / filenames, however with
601     forward slash path separators instead of backslash
602     (i.e. "C:/foo/bar.gig")
603 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
604     apostrophes as well
605 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
606     "LIST FILE INSTRUMENTS <file>" and
607     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
608     about an arbitrary instrument file on the system where the sampler is
609     running on
610 schoenebeck 1471
611 schoenebeck 1424 Version 0.5.0 (15 October 2007)
612 schoenebeck 947
613 schoenebeck 1065 * packaging changes:
614 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
615     API header files anymore
616 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
617     the Doxygen API documentation (explicitly listed in Doxyfile.in)
618 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
619     capable to execute our autoconf environment, thus no need anymore
620     to maintain the compile time configuration file (osx/version.h) for
621     OSX manually (patch by Toshi Nagata)
622 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
623     parameters
624 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
625     C++ API header files, all implementation internal global definitions
626     are now in global_private.h
627     - atomic.h is not exposed to the C++ API anymore
628     - no need to include config.h anymore for using LS's API header files
629     - fixed warnings in API doc generation
630 schoenebeck 1065
631 schoenebeck 947 * general changes:
632     - replaced the old, confusing MIDI program change mechanism by a
633     flexible MIDI instrument mapper which allows to map arbitrary
634 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
635 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
636     loaded on the respective channel when such MIDI program change
637     messages arrive, beside that, each entry allows to define a life-time
638     strategy for the instrument, so the user can define whether the
639     instrument should i.e. be permanently loaded (to be able to switch
640     quickly among sounds) or i.e. loaded just on demand when the
641     respective program change arrives (to safe RAM space), as well as a
642     global volume factor for each entry, so the user can adjust the volume
643     dynamic of his mapped instrument collection without having to modify
644 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
645     MIDI instrument maps and assign each sampler channel individually
646     a certain map, so that i.e. separation of normal instruments and
647     drumkits is possible
648 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
649     MIDI instrument maps, MIDI instruments, FX sends, global volume.
650 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
651     due to a constant size RingBuffer FIFO which is now replaced by a
652     dynamic (unlimited) size std::list FIFO
653 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
654     output channels for being processed by external effect processors
655     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
656     controllers
657 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
658 iliev 1130 - Implemented new, improved notification system
659 schoenebeck 1149 - fixed compilation errors regarding OSX
660     (patch by Toshi Nagata)
661 iliev 1161 - implemented instruments database
662 iliev 1345 - added support for escape sequences to the instruments database
663 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
664     within the sampler's process (by using instrument editor plugins),
665     you'll notice the new "Registered instrument editors:" message on
666 schoenebeck 1407 startup, added a new LSCP command:
667     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
668 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
669     given sampler channel, the plugin path can be overridden at compile
670     time with ./configure --enable-plugin-dir=/some/dir
671 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
672     in the sampler's process to safely edit instruments while playing
673     without a crash (hopefully) by either suspending single regions
674     wherever possible or if unavoidable whole engine(s)
675 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
676     policy and priority on thread level, set a minimum stack size for
677     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
678     threads simply inherited properties of starting thread instead of
679     setting their own policy and priority
680 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
681     main process did not wait for the stack trace process to finish
682     its output
683 persson 1248 - fixed some minor memory leaks
684 schoenebeck 1259 - reenabled assembly features support, at the moment only for
685     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
686 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
687     register, to avoid relocations in the text segment at runtime)
688 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
689 schoenebeck 947
690     * MIDI driver:
691     - dispatch bank select (MSB and LSB) messages
692    
693 schoenebeck 1049 * audio driver:
694     - the ALSA audio output driver parameters now reflect the correct
695     parameter value ranges for the respective selected sound card
696     (patch by Till Wimmer, a bit fixed and extended)
697    
698 persson 951 * Gigasampler format engine:
699     - if a filter is used and EG2 finishes before EG1, let the voice
700     die when EG2 has finished (this fixes a problem with clicks and
701     voice starvation for some gigs)
702 persson 1038 - playback is no longer disabled during instrument loading
703     - all notes playing on a channel that changes its instrument keep
704     playing with the old instrument until they get a note off
705     command
706 persson 1039 - EG fix: a release value of zero could cause noises or crash
707 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
708 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
709     above max sustain level, which means that there is a decay phase
710     even if sustain is 100%
711 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
712     noises or crashes
713 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
714 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
715     supplied to the configure script (fixes #46)
716 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
717     instead of a fix value
718 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
719     127 (solo mode) only kill voices if the respective mode really
720     changed

722 schoenebeck 1244 * LSCP server:
723     - fixed compile time error for old Bison versions
724     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
725 schoenebeck 1245 - parser now supports extended ASCII character set
726     (up to ASCII code 255, i.e. includes now umlauts and accents)
727     - filename arguments in LSCP commands now allow to use escape
728     sequences, that is directly literal as one of: \', \", \\, \n, \r,
729     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
730     code value like \xf2) (fixes bug #24)
731 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
732     least one of their text-based parameters (i.e. name, description):
733     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
734     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
735     "SET DB_INSTRUMENT_DIRECTORY NAME",
736     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
737     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
738     "FIND DB_INSTRUMENT_DIRECTORIES"
739 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
740     occured, the unexpected character and the actually expected, possible
741     character(s), the latter only if less than 5 possibilities)
742 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
743     settings
744 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
745     of strings were treated as being one string containing commas
746     (fixes #57)
747 schoenebeck 1244
748 iliev 959 * Bug fixes:
749     - fixed crash occurring on certain LSCP scripts (Bug 39)
750 persson 1038 - another thread safety fix for lscp "load engine" and "set
751     channel audio output device"
752 iliev 1283 - fixed a crash which occurs when reassigning the same engine
753     on a sampler channel with connected MIDI device
754 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
755     device connected to a sampler channel to number less then or equal
756     to the index of the port to which the sampler channel is connected.
757 iliev 1296 - The previous bindings were not been disconnected when altering
758     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
759     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
760 iliev 1297 - The active stream/voice count statistic was incorrect.
761 iliev 1298 - notification events were not been sent for some sampler
762     channel changes
763 iliev 1305 - added default min and max values to restrict the number of allowed
764     audio output channels and MIDI input ports
765 iliev 1306 - the connection to the PCM interface is now closed when destroying
766     an audio output device
767 schoenebeck 1332 - files with slash in their path or filename could not be loaded
768 iliev 959
769 schoenebeck 1221 * test cases:
770     - updated and fixed (haven't been touched in a while)
771    
772 schoenebeck 937 Version 0.4.0 (24 November 2006)
773 persson 696
774 schoenebeck 697 * packaging changes:
775 capela 868 - changed deprecated copyright attribute to license; added ldconfig
776     to post-(un)install steps; added devel package for liblinuxsampler;
777     to linuxsampler.spec (RPM)
778 schoenebeck 697 - install necessary development header files for allowing 3rd party
779     applications to link against liblinuxsampler
780     - liblinuxsampler's API documentation can be generated with 'make docs'
781     (Doxygen required)
782 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
783     implementation (currently either an integer math solution or a
784     di-harmonic approximation), automatic detection can be overriden
785     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
786     configure script argument though (mandatory for cross-compilation)
787 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
788     provided some on his own (as CXXFLAGS)
789 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
790     messages
791 schoenebeck 852 - added compile time options to allow disabling the various audio and
792     MIDI drivers
793 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
794     (patch by Ebrahim Mayat)
795 schoenebeck 697
796 persson 696 * Gigasampler format engine:
797 schoenebeck 738 - extensive synthesis optimization
798     (reimplementation of EGs and LFO(s), removed synthesis parameter
799     prerendering and the synthesis parameter matrix in general, splitting
800     each audio fragment into subfragments now where each subfragment uses
801 persson 830 constant pitch and filter coefficients. The volume coefficient is
802     linearly interpolated inside a subfragment, unless
803     --disable-interpolate-volume is set.)
804 persson 696 - fine tuning of the EG modulation parameters
805 persson 729 - improved filter cutoff calculation by adding support for the
806     following gig parameters: Cutoff freq (used when no cutoff
807     controller is defined), Control invert, Minimum cutoff, Velocity
808 persson 791 curve and Velocity range. The keyboard tracking now scales
809     cutoff frequency instead of resonance.
810 persson 877 - added support for gig parameter Resonance.
811 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
812 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
813     which can be overridden with --enable-global-attenuation
814 persson 783 - EG fixes: made the length of "attack hold" stage more
815     accurate. Release stage can now start before attack stage
816 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
817     time now has a minimal value to prevent clicks.
818 persson 799 - fixed pitch changes larger than one octave
819 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
820     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
821     all modes can be altered via standard GM messages, that is CC5 for
822     altering portamento time, CC65 for enabling / disabling portamento
823     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
824 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
825     parameter) and crossfade
826 persson 831 - added support for the "attenuation controller threshold" gig
827     parameter
828 persson 832 - added smoothing of volume changes caused by control change
829     messages
830 persson 865 - sample loop parameters are now taken from the DimensionRegion
831     instead of the wave chunk
832     - fixed keyswitching for v3 gigs with a number of keyswitch splits
833     not equal to a power of two
834 persson 877 - reimplementation of the filter algorithm. The new filter is more
835     accurate and supports all gig filter types, including bandreject
836     and lowpass turbo.
837 persson 903 - real support for 24 bit samples - samples are not truncated to
838     16 bits anymore
839     - support for aftertouch (channel pressure, not polyphonic
840     aftertouch)
841 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
842     amplifying from 0)
843 persson 696
844 schoenebeck 711 * LSCP server:
845     - fixed application exit on broken pipe error (fixes bug #20)
846 iliev 793 - fixed the notification messages delay due to lack of
847     network activity (fixes bug #26)
848 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
849     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
850 schoenebeck 711
851 schoenebeck 838 * audio driver:
852     - added aRts audio output driver (by no means RT safe)
853    
854 schoenebeck 775 * MIDI driver:
855     - fixed legacy sysex code which caused dispatching of MIDI SysEx
856     messages several times instead of once
857 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
858     for events (i.e. for offline rendering based MIDI drivers)
859 persson 922 - added checks for bad MIDI data
860 schoenebeck 775
861 schoenebeck 900 * linuxsampler application:
862     - show available sampler engine types on startup
863    
864 schoenebeck 705 * general changes:
865     - support for muting sampler channels and solo mode of the same, two new
866     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
867     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
868     introduced for this, the behavior is the same like on a mixer console
869 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
870     --enable-process-muted-channels which can be used to enable the
871     processing of muted channels.
872 iliev 777 - support for sostenuto pedal
873 iliev 779 - support for monitoring the total number of active voices
874 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
875     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
876 persson 835 - fixed some memory management errors
877 persson 841 - fixed some concurrency problems that could lead to crashes when
878     LSCP commands were executed
879 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
880     sampler channel (fixes bug #36)
881 schoenebeck 705
882 schoenebeck 692 Version 0.3.3 (15 July 2005)
883 schoenebeck 686
884     * packaging changes:
885     - fixed compilation with gcc 4.0
886    
887 schoenebeck 687 * Gigasampler format engine:
888     - LFO preprocessing was performed even though the respective LFO was
889     disabled by the instrument patch (minor efficiency fix)
890 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
891     for volume ramp downs in the same fragment (needed for current voice
892     stealing implementation) then simply inform the user with a warning
893     about possible click sounds and reduce the volume ramp down
894     appropriately instead of cancelling the audio device connection
895 schoenebeck 687
896 schoenebeck 677 Version 0.3.2 (24 June 2005)
897 schoenebeck 609
898     * packaging changes:
899     - updated autotools build files to compile on OS X
900     (conditional compilation of CoreMIDI and MidiShare drivers)
901 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
902     './configure --disable-asm' (definitely not recommended)
903 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
904     - require automake (>= 1.5) for 'make -f Makefile.cvs'
905     (due to 'dist-bzip2' automake option)
906 schoenebeck 649
907     * Gigasampler format engine:
908     - support for the gig parameters for "release velocity response" curves
909     - fine tuning of the EGADSR envelope
910     - volume of release triggered samples now depends on note-on velocity,
911     note length and gig parameter "release trigger decay" instead of
912     note-off velocity.
913 schoenebeck 663 - revised voice stealing
914     (fixes crash and endless loop caused by voice stealing)
915 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
916 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
917     instead of when the respective voice is actually launched
918     (fixes undefined behavior if stolen voices belonged to a key group -
919     this case was followed by a "killed voice survived" error message)
920 schoenebeck 669 - fixed minor issue with null/silence samples
921     (those stole voices even though they don't need a voice at all which
922     resulted in "voice stealing didn't work out" messages)
923 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
924     instrument or audio output device change
925 schoenebeck 654
926 schoenebeck 620 * LSCP server:
927 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
928 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
929 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
930 schoenebeck 609
931 schoenebeck 668 * linuxsampler application:
932     - added command line parameters --lscp-addr and --lscp-port to override
933     default IP address and port of LSCP server
934    
935 schoenebeck 579 Version 0.3.1 (24 May 2005)
936    
937     * initial release
