* VST bugfix: instrument loading hang and crashed the host when the
  plugin was loaded a second time (#174)

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).
31 schoenebeck 2121 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
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)
41 schoenebeck 2124 - implemented support for internal LADSPA effects
42 schoenebeck 2140 - raised limit of program change queue from 100 to 512
43     (as suggested by Alex Stone)

52     - made round robin use a counter for each region instead of each
53     key
54

336 schoenebeck 1601 * general changes:
337     - bugfix: on some POSIX systems instrument editor plugins refused to
338     load as we used a non-portable Linux specific struct field
339     (fixes bug #70, patch by Ronald Baljeu)
340 schoenebeck 1602 - fixed endless loop which occured when loading an instrument editor
341     plugin DLL on Windows systems failed
342 persson 1644 - fixed memory leaks that occurred when liblinuxsampler was unloaded
343     - optimized the SynchronizedConfig class so it doesn't wait
344     unnecessarily long after an update
345 schoenebeck 1653 - added support for notifying instrument editors on note-on / note-off
346     events (e.g. to highlight the pressed keys on the virtual keyboard
347     of gigedit)
348 schoenebeck 1659 - added support for triggering notes by instrument editors (see above)
349 schoenebeck 1653 - be verbose on DLL load errors (on Linux)
350 schoenebeck 1681 - fixed di-harmonic triangle LFO implementation (this LFO implementation
351     is only used by very few systems, most pick the int math
352     implementation, which is usually faster)
353 persson 1748 - fixes for audio drivers with varying buffer sizes
354 persson 1777 - experimental support for running LinuxSampler as a DSSI, LV2 and
355     VST plugin

359     multi-core and multi-cpu systems
360 schoenebeck 1800 - maximum voices and disk streams can now be altered at runtime
361 persson 1825 - fixed CPU feature detection on x86_64 (maybe fixes #108)
362 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
363     be switched on by command line option "--stacktrace" (the automatic
364     stacktrace mechanism seems to be broken on most systems at the moment)
365 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
366     a pointer to the launched InstrumentEditor object
367 schoenebeck 1876 - added optional 3rd party user data parameter for following
368     liblinuxsampler C++ API methods: InstrumentEditor::Main(),
369     InstrumentEditor::Launch(),
370     InstrumentManager::LaunchInstrumentEditor()
371 persson 1887 - theoretical fix: made SynchronizedConfig follow C++0x memory
372     model more strictly
373 persson 1895 - fixes for using large audio device buffers
374 persson 1951 - Windows: add the installation directory to the DLL search path
375     when loading an editor plugin (solves problems with VST and
376     gigedit on systems with other GTK versions installed)
377 schoenebeck 1601
378 schoenebeck 1599 * audio driver:
379     - removed the nonsense audio channel constraint (which was hard coded to
380     max. 100 audio channels) for most audio drivers
381 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
382     opposed to the LSCP specs
383 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
384     reflected the wrong value
385 persson 1644 - fixed a memory management bug in ASIO driver
386 persson 1748 - Makefile fix: JACK_CFLAGS wasn't used
387 persson 1777 - JACK: use jack_client_open instead of the deprecated
388 persson 1748 jack_client_new
389 iliev 1829 - added (experimental) CoreAudio driver
390 persson 1888 - applied old fixes to the ASIO driver that were included in the
391     previous binary release but accidentally never committed to CVS
392     (fixes #117)
393 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
394     win64)
395 persson 1895 - VST: added support for sample rate and buffer size changes
396     - VST: close editor (Fantasia) when the VST is removed
397 persson 1908 - VST: avoid opening Fantasia more than once for each VST instance
398     - VST: export main function as "main" on Linux too (fix for
399     energyXT)

401     stereo
402 persson 1922 - added channel routing, fxsends and midi maps to the settings
403     stored in the plugin state
404 schoenebeck 1930 - performance optimization of AudioChannel::MixTo() and
405     AudioChannel::CopyTo() methods using GCC vector exensions
406     (if available)
407 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
408     exception when getting parameters from a disconnected device
409 schoenebeck 1599
410 persson 1651 * MIDI driver:
411     - added JACK MIDI driver
412 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
413     want to (mis)use it for some purpose ("fixed" in all current MIDI
414     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
415 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
416 persson 1887 CoreMidi or AU
417 persson 1889 - fixed mingw-w64 compilation error in MME driver
418 persson 1924 - made program change handling in MIDI thread real-time safe by
419     moving the logic to a non-RT thread
420 persson 1951 - fixed minor memory leak in ALSA driver
421 persson 1651
422 schoenebeck 1604 * instruments database:
423 iliev 1603 - avoid time consuming samples scanning when adding instruments
424     to the instruments database
425 iliev 1727 - added support for handling lost files in the instruments database
426 iliev 1781 - Implemented option for adding instruments in separate directories
427     in the instruments database
428     (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
429 persson 1908 - work-around for missing fnmatch function on Windows to make
430     instrument database compilable
431 schoenebeck 1930 - added instrument database support on Windows
432     works with both standalone mode and VST plugin.
433     the instruments DB file is located in
434     %USERPROFILE%\.linuxsampler\instruments.db which allows different
435     databases for each windows user
436     if no DB is present it automatically creates the .linuxsampler subdir
437     and then creates an empty DB
438 persson 1943 - fixed recursive import, which was broken on Windows
439 iliev 1603
440 persson 1644 * Gigasampler format engine:
441     - fixed a memory leak that could happen when a channel was deleted
442     while notes were playing
443 persson 1646 - made it possible to load an instrument even if the audio thread
444     isn't running
445 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
446     enough for piano gigs with pedal noise samples
447 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
448     respective FX send MIDI controller was used
449 schoenebeck 1724 - added support for GM global device volume SysEx message
450 schoenebeck 1762 (can be selected at compile time to either apply globally to the
451     whole sampler [default] or only to the sampler channels that are
452     connected to the respective MIDI input port the SysEx message arrived
453     on)
454 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
455     sometimes wrongly killed in the same buffer, causing no sound to
456     be played
457 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
458     which is usally used to switch a part between chromatic sounds and
459     drumkit sounds (as opposed to their common default setting of MIDI
460     part 10 being a drumkit part and all other ones chromatic parts), in
461     LS however one can switch between the first 16 MIDI instrument maps
462     defined for the sampler
463 persson 1764 - made it possible to create multiple sample channels even if the
464     audio thread isn't running
465 persson 1844 - fixed crash when removing channel with active voices (#116)
466 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
467     un-cache the respective sample if it's really not used by any
468     sampler engine anymore
469     - re-cache samples in case they were changed by an instrument editor,
470     e.g. when a sample was added while playing (#82)
471 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
472     same time stamp as the voice's note-on event and occured both in the
473     same audio fragment cycle (fixes bug #112)
474 persson 1858 - added support for the "fine tune" and "pitch bend range"
475     instrument-level gig parameters
476     - fixed minor artifacts in pitch bend handling
477 schoenebeck 1860 - added support for GS Reset SysEx message
478 persson 1862 - allow gig files to use unlimited downward pitch shifting
479     - added a limit check for upward pitch shifting
480 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
481     note was silent
482 persson 1923 - fixed crash happening when a pitch bend event arrived at the
483     same time a new instrument was loading
484 persson 1644
485 schoenebeck 1687 * LSCP server:
486     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
487     react on MIDI data arriving on certain sampler channels (so far only
488     Note-On and Note-Off events are sent via this LSCP event)
489 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
490     react on MIDI data arriving on certain MIDI input devices (so far only
491     Note-On and Note-Off events are sent via this LSCP event)
492 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
493     SET DB_INSTRUMENT FILE_PATH
494 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
495     frontends to send MIDI messages to specific sampler channel
496     - added two additional fields to GET FILE INSTRUMENT INFO command -
497     KEY_BINDINGS and KEYSWITCH_BINDINGS
498 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
499     was incorrect
500 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
501 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
502     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
503     be triggered respectively
504     - added new LSCP command "SET STREAMS" to globally alter the maximum
505     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
506     which will be triggered respectively
507 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
508     a gigedit file dialog is opened)
509 iliev 1848 - close all connections when LSCPServer is deleted
510 iliev 1882 - hard close of all sockets on exit
511 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
512     driver
513 schoenebeck 1687
514 iliev 1761 * Bug fixes:
515     - fixed a crash which occurs when removing a sampler channel waiting
516     to start instrument loading after another channel
517 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
518     instrument loading in progress (bug #113)
519 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
520     instrument with PERSISTENT load mode
521 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
522     - fixed memory leaks when issuing the following LSCP commands:
523     GET AUDIO_OUTPUT_DRIVER INFO
524     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
525     GET MIDI_INPUT_DRIVER INFO
526     GET MIDI_INPUT_DRIVER_PARAMETER INFO
527     - fixed possible compilation error when sqlite is not present
528 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
529 iliev 1847 - fixed crash when changing the audio output device of a sampler
530     channel with loaded instrument and start playing notes
531 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
532 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
533     PowerPC, which probably could cause crashes on that platform
534 persson 1889 - fixed a memory management error which could cause a crash when a
535     plugin was unloaded
536 persson 1896 - bugfix: two private structs had the same name, which could cause
537     problems if the linker chose the wrong constructor
538 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
539     Windows
540 iliev 1761
541    
542 schoenebeck 1560 Version 0.5.1 (6 December 2007)
543 schoenebeck 1454
544     * packaging changes:
545     - added autoconf checks for pthread library
546     - added autoconf check for pthread bug found on certain NPTL-enabled
547     glibc versions (see Gentoo bug report #194076)
548 senoner 1502 - added autoconf checks for MS Windows
549 schoenebeck 1454
550 persson 1455 * general changes:
551     - bugfix: the thread used by an editor plugin didn't die when the
552     editor closed
553 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
554     out all the space. operator--() did not apply size_mask after
555     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
556     order to avoid problems with the _NonVolatileReader functions.
557     - bugfix: Stream.h: added a missing divide by BytesPerSample in
558     GetWriteSpace(). Since this function is currently only used in
559     the stream's qsort() compare function, it didn't trigger any
560     bugs.
561     - Resampler.h, Synthesizer.h: cubic interpolation now works in
562     24bit mode too. Faster method to read 24bit words on little
563     endian machines (x86): replaced 3 byte reads + shifts with a 1
564     unaligned 32bit read and shift
565     - experimental support for MS Windows (MIDI input via MME, AUDIO
566     output via ASIO)
567     - made handling of SIGINT signal (Ctrl-C) a bit more robust
568 iliev 1541 - support for monitoring the total number of active disk streams
569     (new LSCP commands: GET TOTAL_STREAM_COUNT,
570     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
571 persson 1455
572 senoner 1500 * AUDIO driver:
573 persson 1534 - added Windows ASIO low latency audio driver
574 senoner 1500
575 senoner 1485 * MIDI driver:
576 schoenebeck 1495 - added MME Windows MIDI driver
577 senoner 1485
578 schoenebeck 1471 * LSCP server:
579     - added support for Windows style path / filenames, however with
580     forward slash path separators instead of backslash
581     (i.e. "C:/foo/bar.gig")
582 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
583     apostrophes as well
584 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
585     "LIST FILE INSTRUMENTS <file>" and
586     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
587     about an arbitrary instrument file on the system where the sampler is
588     running on
589 schoenebeck 1471
590 schoenebeck 1424 Version 0.5.0 (15 October 2007)
591 schoenebeck 947
592 schoenebeck 1065 * packaging changes:
593 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
594     API header files anymore
595 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
596     the Doxygen API documentation (explicitly listed in Doxyfile.in)
597 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
598     capable to execute our autoconf environment, thus no need anymore
599     to maintain the compile time configuration file (osx/version.h) for
600     OSX manually (patch by Toshi Nagata)
601 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
602     parameters
603 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
604     C++ API header files, all implementation internal global definitions
605     are now in global_private.h
606     - atomic.h is not exposed to the C++ API anymore
607     - no need to include config.h anymore for using LS's API header files
608     - fixed warnings in API doc generation
609 schoenebeck 1065
610 schoenebeck 947 * general changes:
611     - replaced the old, confusing MIDI program change mechanism by a
612     flexible MIDI instrument mapper which allows to map arbitrary
613 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
614 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
615     loaded on the respective channel when such MIDI program change
616     messages arrive, beside that, each entry allows to define a life-time
617     strategy for the instrument, so the user can define whether the
618     instrument should i.e. be permanently loaded (to be able to switch
619     quickly among sounds) or i.e. loaded just on demand when the
620     respective program change arrives (to safe RAM space), as well as a
621     global volume factor for each entry, so the user can adjust the volume
622     dynamic of his mapped instrument collection without having to modify
623 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
624     MIDI instrument maps and assign each sampler channel individually
625     a certain map, so that i.e. separation of normal instruments and
626     drumkits is possible
627 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
628     MIDI instrument maps, MIDI instruments, FX sends, global volume.
629 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
630     due to a constant size RingBuffer FIFO which is now replaced by a
631     dynamic (unlimited) size std::list FIFO
632 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
633     output channels for being processed by external effect processors
634     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
635     controllers
636 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
637 iliev 1130 - Implemented new, improved notification system
638 schoenebeck 1149 - fixed compilation errors regarding OSX
639     (patch by Toshi Nagata)
640 iliev 1161 - implemented instruments database
641 iliev 1345 - added support for escape sequences to the instruments database
642 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
643     within the sampler's process (by using instrument editor plugins),
644     you'll notice the new "Registered instrument editors:" message on
645 schoenebeck 1407 startup, added a new LSCP command:
646     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
647 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
648     given sampler channel, the plugin path can be overridden at compile
649     time with ./configure --enable-plugin-dir=/some/dir
650 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
651     in the sampler's process to safely edit instruments while playing
652     without a crash (hopefully) by either suspending single regions
653     wherever possible or if unavoidable whole engine(s)
654 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
655     policy and priority on thread level, set a minimum stack size for
656     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
657     threads simply inherited properties of starting thread instead of
658     setting their own policy and priority
659 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
660     main process did not wait for the stack trace process to finish
661     its output
662 persson 1248 - fixed some minor memory leaks
663 schoenebeck 1259 - reenabled assembly features support, at the moment only for
664     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
665 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
666     register, to avoid relocations in the text segment at runtime)
667 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
668 schoenebeck 947
669     * MIDI driver:
670     - dispatch bank select (MSB and LSB) messages
671    
672 schoenebeck 1049 * audio driver:
673     - the ALSA audio output driver parameters now reflect the correct
674     parameter value ranges for the respective selected sound card
675     (patch by Till Wimmer, a bit fixed and extended)
676    
677 persson 951 * Gigasampler format engine:
678     - if a filter is used and EG2 finishes before EG1, let the voice
679     die when EG2 has finished (this fixes a problem with clicks and
680     voice starvation for some gigs)
681 persson 1038 - playback is no longer disabled during instrument loading
682     - all notes playing on a channel that changes its instrument keep
683     playing with the old instrument until they get a note off
684     command
685 persson 1039 - EG fix: a release value of zero could cause noises or crash
686 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
687 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
688     above max sustain level, which means that there is a decay phase
689     even if sustain is 100%
690 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
691     noises or crashes
692 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
693 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
694     supplied to the configure script (fixes #46)
695 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
696     instead of a fix value
697 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
698     127 (solo mode) only kill voices if the respective mode really
699     changed
700 persson 951
701 schoenebeck 1244 * LSCP server:
702     - fixed compile time error for old Bison versions
703     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
704 schoenebeck 1245 - parser now supports extended ASCII character set
705     (up to ASCII code 255, i.e. includes now umlauts and accents)
706     - filename arguments in LSCP commands now allow to use escape
707     sequences, that is directly literal as one of: \', \", \\, \n, \r,
708     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
709     code value like \xf2) (fixes bug #24)
710 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
711     least one of their text-based parameters (i.e. name, description):
712     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
713     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
714     "SET DB_INSTRUMENT_DIRECTORY NAME",
715     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
716     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
717     "FIND DB_INSTRUMENT_DIRECTORIES"
718 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
719     occured, the unexpected character and the actually expected, possible
720     character(s), the latter only if less than 5 possibilities)
721 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale

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