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

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

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

333 persson 1897 - Windows: look for editor plugins and Fantasia using base
334 schoenebeck 1928 directory of liblinuxsampler dll (look in the same directory and one
335     directory above)
336 persson 1899 - configure script fix: removed unconditional use of SSE
337 persson 1923 - fixed building with sqlite installed in a non-standard directory
338 persson 1931 - when cross-compiling, don't try to create instruments.db
339     - fix for new mingw-w64 version, which has usleep
340 schoenebeck 1639
341 schoenebeck 1601 * general changes:
342     - bugfix: on some POSIX systems instrument editor plugins refused to
343     load as we used a non-portable Linux specific struct field
344     (fixes bug #70, patch by Ronald Baljeu)
345 schoenebeck 1602 - fixed endless loop which occured when loading an instrument editor
346     plugin DLL on Windows systems failed
347 persson 1644 - fixed memory leaks that occurred when liblinuxsampler was unloaded
348     - optimized the SynchronizedConfig class so it doesn't wait
349     unnecessarily long after an update
350 schoenebeck 1653 - added support for notifying instrument editors on note-on / note-off
351     events (e.g. to highlight the pressed keys on the virtual keyboard
352     of gigedit)
353 schoenebeck 1659 - added support for triggering notes by instrument editors (see above)
354 schoenebeck 1653 - be verbose on DLL load errors (on Linux)
355 schoenebeck 1681 - fixed di-harmonic triangle LFO implementation (this LFO implementation
356     is only used by very few systems, most pick the int math
357     implementation, which is usually faster)
358 persson 1748 - fixes for audio drivers with varying buffer sizes
359 persson 1777 - experimental support for running LinuxSampler as a DSSI, LV2 and
360     VST plugin
361 iliev 1789 - notification events for stream/voice count statistics are now sent

363 persson 1790 - added memory ordering constraints to improve stability on
364     multi-core and multi-cpu systems
365 schoenebeck 1800 - maximum voices and disk streams can now be altered at runtime
366 persson 1825 - fixed CPU feature detection on x86_64 (maybe fixes #108)
367 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
368     be switched on by command line option "--stacktrace" (the automatic
369     stacktrace mechanism seems to be broken on most systems at the moment)
370 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
371     a pointer to the launched InstrumentEditor object
372 schoenebeck 1876 - added optional 3rd party user data parameter for following
373     liblinuxsampler C++ API methods: InstrumentEditor::Main(),
374     InstrumentEditor::Launch(),
375     InstrumentManager::LaunchInstrumentEditor()
376 persson 1887 - theoretical fix: made SynchronizedConfig follow C++0x memory
377     model more strictly
378 persson 1895 - fixes for using large audio device buffers
379 persson 1951 - Windows: add the installation directory to the DLL search path
380     when loading an editor plugin (solves problems with VST and
381     gigedit on systems with other GTK versions installed)
382 schoenebeck 1601
383 schoenebeck 1599 * audio driver:
384     - removed the nonsense audio channel constraint (which was hard coded to
385     max. 100 audio channels) for most audio drivers
386 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
387     opposed to the LSCP specs
388 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
389     reflected the wrong value
390 persson 1644 - fixed a memory management bug in ASIO driver
391 persson 1748 - Makefile fix: JACK_CFLAGS wasn't used
392 persson 1777 - JACK: use jack_client_open instead of the deprecated
393 persson 1748 jack_client_new
394 iliev 1829 - added (experimental) CoreAudio driver
395 persson 1888 - applied old fixes to the ASIO driver that were included in the
396     previous binary release but accidentally never committed to CVS
397     (fixes #117)
398 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
399     win64)
400 persson 1895 - VST: added support for sample rate and buffer size changes
401     - VST: close editor (Fantasia) when the VST is removed
402 persson 1908 - VST: avoid opening Fantasia more than once for each VST instance

404     energyXT)
405 persson 1917 - VST: changed number of output channels from one stereo to 16
406     stereo
407 persson 1922 - added channel routing, fxsends and midi maps to the settings
408     stored in the plugin state
409 schoenebeck 1930 - performance optimization of AudioChannel::MixTo() and
410     AudioChannel::CopyTo() methods using GCC vector exensions
411     (if available)
412 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
413     exception when getting parameters from a disconnected device
414 schoenebeck 1599
415 persson 1651 * MIDI driver:
416     - added JACK MIDI driver
417 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
418     want to (mis)use it for some purpose ("fixed" in all current MIDI
419     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
420 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
421 persson 1887 CoreMidi or AU
422 persson 1889 - fixed mingw-w64 compilation error in MME driver
423 persson 1924 - made program change handling in MIDI thread real-time safe by
424     moving the logic to a non-RT thread
425 persson 1951 - fixed minor memory leak in ALSA driver
426 persson 1651
427 schoenebeck 1604 * instruments database:
428 iliev 1603 - avoid time consuming samples scanning when adding instruments
429     to the instruments database
430 iliev 1727 - added support for handling lost files in the instruments database
431 iliev 1781 - Implemented option for adding instruments in separate directories
432     in the instruments database
433     (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
434 persson 1908 - work-around for missing fnmatch function on Windows to make
435     instrument database compilable
436 schoenebeck 1930 - added instrument database support on Windows
437     works with both standalone mode and VST plugin.
438     the instruments DB file is located in
439     %USERPROFILE%\.linuxsampler\instruments.db which allows different
440     databases for each windows user
441     if no DB is present it automatically creates the .linuxsampler subdir
442     and then creates an empty DB
443 persson 1943 - fixed recursive import, which was broken on Windows
444 iliev 1603
445 persson 1644 * Gigasampler format engine:
446     - fixed a memory leak that could happen when a channel was deleted
447     while notes were playing
448 persson 1646 - made it possible to load an instrument even if the audio thread
449     isn't running
450 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
451     enough for piano gigs with pedal noise samples
452 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
453     respective FX send MIDI controller was used
454 schoenebeck 1724 - added support for GM global device volume SysEx message
455 schoenebeck 1762 (can be selected at compile time to either apply globally to the
456     whole sampler [default] or only to the sampler channels that are
457     connected to the respective MIDI input port the SysEx message arrived
458     on)
459 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
460     sometimes wrongly killed in the same buffer, causing no sound to
461     be played
462 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
463     which is usally used to switch a part between chromatic sounds and
464     drumkit sounds (as opposed to their common default setting of MIDI
465     part 10 being a drumkit part and all other ones chromatic parts), in
466     LS however one can switch between the first 16 MIDI instrument maps
467     defined for the sampler
468 persson 1764 - made it possible to create multiple sample channels even if the
469     audio thread isn't running
470 persson 1844 - fixed crash when removing channel with active voices (#116)
471 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
472     un-cache the respective sample if it's really not used by any
473     sampler engine anymore
474     - re-cache samples in case they were changed by an instrument editor,
475     e.g. when a sample was added while playing (#82)
476 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
477     same time stamp as the voice's note-on event and occured both in the
478     same audio fragment cycle (fixes bug #112)
479 persson 1858 - added support for the "fine tune" and "pitch bend range"
480     instrument-level gig parameters
481     - fixed minor artifacts in pitch bend handling
482 schoenebeck 1860 - added support for GS Reset SysEx message
483 persson 1862 - allow gig files to use unlimited downward pitch shifting
484     - added a limit check for upward pitch shifting
485 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
486     note was silent
487 persson 1923 - fixed crash happening when a pitch bend event arrived at the
488     same time a new instrument was loading
489 persson 1644
490 schoenebeck 1687 * LSCP server:
491     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
492     react on MIDI data arriving on certain sampler channels (so far only
493     Note-On and Note-Off events are sent via this LSCP event)
494 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
495     react on MIDI data arriving on certain MIDI input devices (so far only
496     Note-On and Note-Off events are sent via this LSCP event)
497 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
498     SET DB_INSTRUMENT FILE_PATH
499 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
500     frontends to send MIDI messages to specific sampler channel
501     - added two additional fields to GET FILE INSTRUMENT INFO command -
502     KEY_BINDINGS and KEYSWITCH_BINDINGS
503 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
504     was incorrect
505 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
506 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
507     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
508     be triggered respectively
509     - added new LSCP command "SET STREAMS" to globally alter the maximum
510     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
511     which will be triggered respectively
512 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
513     a gigedit file dialog is opened)
514 iliev 1848 - close all connections when LSCPServer is deleted
515 iliev 1882 - hard close of all sockets on exit
516 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
517     driver
518 schoenebeck 1687
519 iliev 1761 * Bug fixes:
520     - fixed a crash which occurs when removing a sampler channel waiting
521     to start instrument loading after another channel
522 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
523     instrument loading in progress (bug #113)
524 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
525     instrument with PERSISTENT load mode
526 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
527     - fixed memory leaks when issuing the following LSCP commands:
528     GET AUDIO_OUTPUT_DRIVER INFO
529     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
530     GET MIDI_INPUT_DRIVER INFO
531     GET MIDI_INPUT_DRIVER_PARAMETER INFO
532     - fixed possible compilation error when sqlite is not present
533 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
534 iliev 1847 - fixed crash when changing the audio output device of a sampler
535     channel with loaded instrument and start playing notes
536 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
537 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
538     PowerPC, which probably could cause crashes on that platform
539 persson 1889 - fixed a memory management error which could cause a crash when a
540     plugin was unloaded
541 persson 1896 - bugfix: two private structs had the same name, which could cause
542     problems if the linker chose the wrong constructor
543 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
544     Windows
545 iliev 1761
546    
547 schoenebeck 1560 Version 0.5.1 (6 December 2007)
548 schoenebeck 1454
549     * packaging changes:
550     - added autoconf checks for pthread library
551     - added autoconf check for pthread bug found on certain NPTL-enabled
552     glibc versions (see Gentoo bug report #194076)
553 senoner 1502 - added autoconf checks for MS Windows
554 schoenebeck 1454
555 persson 1455 * general changes:
556     - bugfix: the thread used by an editor plugin didn't die when the
557     editor closed
558 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
559     out all the space. operator--() did not apply size_mask after
560     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
561     order to avoid problems with the _NonVolatileReader functions.
562     - bugfix: Stream.h: added a missing divide by BytesPerSample in
563     GetWriteSpace(). Since this function is currently only used in
564     the stream's qsort() compare function, it didn't trigger any
565     bugs.
566     - Resampler.h, Synthesizer.h: cubic interpolation now works in
567     24bit mode too. Faster method to read 24bit words on little
568     endian machines (x86): replaced 3 byte reads + shifts with a 1
569     unaligned 32bit read and shift
570     - experimental support for MS Windows (MIDI input via MME, AUDIO
571     output via ASIO)
572     - made handling of SIGINT signal (Ctrl-C) a bit more robust
573 iliev 1541 - support for monitoring the total number of active disk streams
574     (new LSCP commands: GET TOTAL_STREAM_COUNT,
575     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
576 persson 1455
577 senoner 1500 * AUDIO driver:
578 persson 1534 - added Windows ASIO low latency audio driver
579 senoner 1500
580 senoner 1485 * MIDI driver:
581 schoenebeck 1495 - added MME Windows MIDI driver
582 senoner 1485
583 schoenebeck 1471 * LSCP server:
584     - added support for Windows style path / filenames, however with
585     forward slash path separators instead of backslash
586     (i.e. "C:/foo/bar.gig")
587 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
588     apostrophes as well
589 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
590     "LIST FILE INSTRUMENTS <file>" and
591     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
592     about an arbitrary instrument file on the system where the sampler is
593     running on
594 schoenebeck 1471
595 schoenebeck 1424 Version 0.5.0 (15 October 2007)
596 schoenebeck 947
597 schoenebeck 1065 * packaging changes:
598 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
599     API header files anymore
600 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
601     the Doxygen API documentation (explicitly listed in Doxyfile.in)
602 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
603     capable to execute our autoconf environment, thus no need anymore
604     to maintain the compile time configuration file (osx/version.h) for
605     OSX manually (patch by Toshi Nagata)
606 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
607     parameters
608 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
609     C++ API header files, all implementation internal global definitions
610     are now in global_private.h
611     - atomic.h is not exposed to the C++ API anymore
612     - no need to include config.h anymore for using LS's API header files
613     - fixed warnings in API doc generation
614 schoenebeck 1065
615 schoenebeck 947 * general changes:
616     - replaced the old, confusing MIDI program change mechanism by a
617     flexible MIDI instrument mapper which allows to map arbitrary
618 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
619 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
620     loaded on the respective channel when such MIDI program change
621     messages arrive, beside that, each entry allows to define a life-time
622     strategy for the instrument, so the user can define whether the
623     instrument should i.e. be permanently loaded (to be able to switch
624     quickly among sounds) or i.e. loaded just on demand when the
625     respective program change arrives (to safe RAM space), as well as a
626     global volume factor for each entry, so the user can adjust the volume
627     dynamic of his mapped instrument collection without having to modify
628 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
629     MIDI instrument maps and assign each sampler channel individually
630     a certain map, so that i.e. separation of normal instruments and
631     drumkits is possible
632 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
633     MIDI instrument maps, MIDI instruments, FX sends, global volume.
634 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
635     due to a constant size RingBuffer FIFO which is now replaced by a
636     dynamic (unlimited) size std::list FIFO
637 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
638     output channels for being processed by external effect processors
639     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
640     controllers
641 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
642 iliev 1130 - Implemented new, improved notification system
643 schoenebeck 1149 - fixed compilation errors regarding OSX
644     (patch by Toshi Nagata)
645 iliev 1161 - implemented instruments database
646 iliev 1345 - added support for escape sequences to the instruments database
647 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
648     within the sampler's process (by using instrument editor plugins),
649     you'll notice the new "Registered instrument editors:" message on
650 schoenebeck 1407 startup, added a new LSCP command:
651     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
652 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
653     given sampler channel, the plugin path can be overridden at compile
654     time with ./configure --enable-plugin-dir=/some/dir
655 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
656     in the sampler's process to safely edit instruments while playing
657     without a crash (hopefully) by either suspending single regions
658     wherever possible or if unavoidable whole engine(s)
659 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
660     policy and priority on thread level, set a minimum stack size for
661     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
662     threads simply inherited properties of starting thread instead of
663     setting their own policy and priority
664 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
665     main process did not wait for the stack trace process to finish
666     its output
667 persson 1248 - fixed some minor memory leaks
668 schoenebeck 1259 - reenabled assembly features support, at the moment only for
669     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
670 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
671     register, to avoid relocations in the text segment at runtime)
672 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
673 schoenebeck 947
674     * MIDI driver:
675     - dispatch bank select (MSB and LSB) messages
676    
677 schoenebeck 1049 * audio driver:
678     - the ALSA audio output driver parameters now reflect the correct
679     parameter value ranges for the respective selected sound card
680     (patch by Till Wimmer, a bit fixed and extended)
681    
682 persson 951 * Gigasampler format engine:
683     - if a filter is used and EG2 finishes before EG1, let the voice
684     die when EG2 has finished (this fixes a problem with clicks and
685     voice starvation for some gigs)
686 persson 1038 - playback is no longer disabled during instrument loading
687     - all notes playing on a channel that changes its instrument keep
688     playing with the old instrument until they get a note off
689     command
690 persson 1039 - EG fix: a release value of zero could cause noises or crash
691 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
692 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
693     above max sustain level, which means that there is a decay phase
694     even if sustain is 100%
695 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
696     noises or crashes
697 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
698 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
699     supplied to the configure script (fixes #46)
700 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
701     instead of a fix value
702 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
703     127 (solo mode) only kill voices if the respective mode really
704     changed
705 persson 951
706 schoenebeck 1244 * LSCP server:
707     - fixed compile time error for old Bison versions
708     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
709 schoenebeck 1245 - parser now supports extended ASCII character set
710     (up to ASCII code 255, i.e. includes now umlauts and accents)
711     - filename arguments in LSCP commands now allow to use escape
712     sequences, that is directly literal as one of: \', \", \\, \n, \r,
713     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
714     code value like \xf2) (fixes bug #24)
715 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
716     least one of their text-based parameters (i.e. name, description):

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