1 schoenebeck 1993 Version CVS HEAD (?)
2    
3 persson 2086 * packaging changes:
4     - fixed building with newer MinGW-w64
5 persson 2183 - Mac OS X: support the new dir for Core Audio SDK
6     - Mac OS X: fixed building outside source directory
7     - made sure all source files for hostplugins are included when
8     doing "make dist"
9     - removed empty directories left from the cvs to svn migration
10 persson 2185 - fixed compilation with gcc 4.6.1
11 persson 2203 - another "make dist" fix, for the LV2 plugin

13 persson 2197 - minor Makefile fix for building lscpparser when build and source
14     directories are separate
15 persson 2203 - Mac OS X: made it possible to specify plugin installation dir to
16     configure
17 persson 2208 - Mac OS X: Makefile fix for the install-strip target
18 persson 2335 - fixed compilation with gcc 4.7
19 persson 2343 - fixed configure script error with old autoconf versions

26 persson 2382
27 persson 2086 * general changes:
28 iliev 2012 - Refactoring: moved the independent code from
29     the Gigasampler format engine to base classes
30 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
31     respective profiling code is currently broken
32 schoenebeck 2053 - Introduced support for optional environment variable
33     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
34     where the sampler shall look for instrument editor plugins
35     (patch by Luis Garrido, slightly modified).
36 schoenebeck 2121 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
37     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
38     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
39     note (in this implementation of the sampler its simply hard routed to
40     the 1st effect send of the sampler channel, no matter what the actual
41     effect type is)
42     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
43     note (in this implementation of the sampler its simply hard routed to
44     the 2nd effect send of the sampler channel, no matter what the actual
45     effect type is)
46 schoenebeck 2124 - implemented support for internal LADSPA effects
47 schoenebeck 2140 - raised limit of program change queue from 100 to 512

55     instrument on an engine channel (a.k.a. part). Some GigaStudio
56     instruments for example are splitted over several files like
57     "Foo.gig", "Foo.gx01", "Foo.gx02", ...
58 schoenebeck 2375 - Added new C++ API method Sampler::GetGlobalMaxVoices().
59     - Added new C++ API method Sampler::GetGlobalMaxStreams().

73 persson 2382 - bugfix: pitch LFO controller "internal+aftertouch" was broken
74     - bugfix: filter keyboard tracking was broken

77     - handle special case when pan parameter in gig file has max or
78     min value
79 schoenebeck 2396 - Exclusive Groups: don't ever stop voices of the same note,
80     doesn't sound naturally with a drumkit

298     - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
299     the driver will automatically connect to other CoreMIDI clients' ports

363 iliev 2201 - Fixed possible crashes due to corrupted MIDI/audio device list
364     after MIDI/audio device creation failure
365 schoenebeck 2275 - When creating MIDI instrument map entries with "PERSISTENT" type, the
366     instruments were uselessly precached with zero samples, however it still
367     took the full preloading time and on 1st program change the respective
368     instrument was completely reloaded again.
369 persson 2277 - fixed handling of rapid bank select and program change messages
370     sent to the same sampler channel (patch from the Open Octave

391 schoenebeck 1599
392 schoenebeck 1639 * packaging changes:
393     - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

438 schoenebeck 1830 - automatic stacktrace mechanism is now turned off by default and can
439     be switched on by command line option "--stacktrace" (the automatic
440     stacktrace mechanism seems to be broken on most systems at the moment)
441 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
442     a pointer to the launched InstrumentEditor object
443 schoenebeck 1876 - added optional 3rd party user data parameter for following

454 schoenebeck 1599 * audio driver:
455     - removed the nonsense audio channel constraint (which was hard coded to
456     max. 100 audio channels) for most audio drivers
457 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
458     opposed to the LSCP specs
459 schoenebeck 1607 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
460     reflected the wrong value
461 persson 1644 - fixed a memory management bug in ASIO driver
462 persson 1748 - Makefile fix: JACK_CFLAGS wasn't used

464 persson 1748 jack_client_new
465 iliev 1829 - added (experimental) CoreAudio driver
466 persson 1888 - applied old fixes to the ASIO driver that were included in the
467     previous binary release but accidentally never committed to CVS
468     (fixes #117)
469 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
470     win64)
471 persson 1895 - VST: added support for sample rate and buffer size changes
472     - VST: close editor (Fantasia) when the VST is removed

479     stored in the plugin state
480 schoenebeck 1930 - performance optimization of AudioChannel::MixTo() and
481     AudioChannel::CopyTo() methods using GCC vector exensions
482     (if available)
483 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
484     exception when getting parameters from a disconnected device
485 schoenebeck 1599
486 persson 1651 * MIDI driver:
487     - added JACK MIDI driver
488 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
489     want to (mis)use it for some purpose ("fixed" in all current MIDI
490     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
491 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
492 persson 1887 CoreMidi or AU
493 persson 1889 - fixed mingw-w64 compilation error in MME driver
494 persson 1924 - made program change handling in MIDI thread real-time safe by

500     to the instruments database
501 iliev 1727 - added support for handling lost files in the instruments database
502 iliev 1781 - Implemented option for adding instruments in separate directories
503     in the instruments database

505 persson 1908 - work-around for missing fnmatch function on Windows to make
506     instrument database compilable
507 schoenebeck 1930 - added instrument database support on Windows
508     works with both standalone mode and VST plugin.
509     the instruments DB file is located in
510     %USERPROFILE%\.linuxsampler\instruments.db which allows different
511     databases for each windows user
512     if no DB is present it automatically creates the .linuxsampler subdir
513     and then creates an empty DB
514 persson 1943 - fixed recursive import, which was broken on Windows
515 iliev 1603
516 persson 1644 * Gigasampler format engine:
517     - fixed a memory leak that could happen when a channel was deleted
518     while notes were playing
519 persson 1646 - made it possible to load an instrument even if the audio thread
520     isn't running
521 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
522     enough for piano gigs with pedal noise samples
523 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
524     respective FX send MIDI controller was used
525 schoenebeck 1724 - added support for GM global device volume SysEx message
526 schoenebeck 1762 (can be selected at compile time to either apply globally to the
527     whole sampler [default] or only to the sampler channels that are
528     connected to the respective MIDI input port the SysEx message arrived
529     on)
530 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
531     sometimes wrongly killed in the same buffer, causing no sound to
532     be played
533 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
534     which is usally used to switch a part between chromatic sounds and
535     drumkit sounds (as opposed to their common default setting of MIDI
536     part 10 being a drumkit part and all other ones chromatic parts), in
537     LS however one can switch between the first 16 MIDI instrument maps
538     defined for the sampler
539 persson 1764 - made it possible to create multiple sample channels even if the
540     audio thread isn't running
541 persson 1844 - fixed crash when removing channel with active voices (#116)
542 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
543     un-cache the respective sample if it's really not used by any
544     sampler engine anymore
545     - re-cache samples in case they were changed by an instrument editor,
546     e.g. when a sample was added while playing (#82)
547 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
548     same time stamp as the voice's note-on event and occured both in the
549     same audio fragment cycle (fixes bug #112)
550 persson 1858 - added support for the "fine tune" and "pitch bend range"
551     instrument-level gig parameters
552     - fixed minor artifacts in pitch bend handling
553 schoenebeck 1860 - added support for GS Reset SysEx message
554 persson 1862 - allow gig files to use unlimited downward pitch shifting
555     - added a limit check for upward pitch shifting
556 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
557     note was silent
558 persson 1923 - fixed crash happening when a pitch bend event arrived at the
559     same time a new instrument was loading
560 persson 1644
561 schoenebeck 1687 * LSCP server:
562     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
563     react on MIDI data arriving on certain sampler channels (so far only
564     Note-On and Note-Off events are sent via this LSCP event)
565 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
566     react on MIDI data arriving on certain MIDI input devices (so far only
567     Note-On and Note-Off events are sent via this LSCP event)
568 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
569     SET DB_INSTRUMENT FILE_PATH
570 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
571     frontends to send MIDI messages to specific sampler channel
572     - added two additional fields to GET FILE INSTRUMENT INFO command -
573     KEY_BINDINGS and KEYSWITCH_BINDINGS
574 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
575     was incorrect
576 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
577 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
578     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
579     be triggered respectively
580     - added new LSCP command "SET STREAMS" to globally alter the maximum
581     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
582     which will be triggered respectively
583 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
584     a gigedit file dialog is opened)
585 iliev 1848 - close all connections when LSCPServer is deleted
586 iliev 1882 - hard close of all sockets on exit
587 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
588     driver
589 schoenebeck 1687
590 iliev 1761 * Bug fixes:
591     - fixed a crash which occurs when removing a sampler channel waiting
592     to start instrument loading after another channel
593 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
594     instrument loading in progress (bug #113)
595 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
596     instrument with PERSISTENT load mode
597 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
598     - fixed memory leaks when issuing the following LSCP commands:
599     GET AUDIO_OUTPUT_DRIVER INFO
600     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
601     GET MIDI_INPUT_DRIVER INFO
602     GET MIDI_INPUT_DRIVER_PARAMETER INFO
603     - fixed possible compilation error when sqlite is not present
604 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
605 iliev 1847 - fixed crash when changing the audio output device of a sampler
606     channel with loaded instrument and start playing notes
607 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
608 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
609     PowerPC, which probably could cause crashes on that platform
610 persson 1889 - fixed a memory management error which could cause a crash when a
611     plugin was unloaded
612 persson 1896 - bugfix: two private structs had the same name, which could cause
613     problems if the linker chose the wrong constructor
614 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
615     Windows
616 iliev 1761
617    
618 schoenebeck 1560 Version 0.5.1 (6 December 2007)
619 schoenebeck 1454
620     * packaging changes:
621     - added autoconf checks for pthread library
622     - added autoconf check for pthread bug found on certain NPTL-enabled
623     glibc versions (see Gentoo bug report #194076)
624 senoner 1502 - added autoconf checks for MS Windows
625 schoenebeck 1454
626 persson 1455 * general changes:
627     - bugfix: the thread used by an editor plugin didn't die when the
628     editor closed
629 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
630     out all the space. operator--() did not apply size_mask after
631     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
632     order to avoid problems with the _NonVolatileReader functions.
633     - bugfix: Stream.h: added a missing divide by BytesPerSample in
634     GetWriteSpace(). Since this function is currently only used in
635     the stream's qsort() compare function, it didn't trigger any
636     bugs.
637     - Resampler.h, Synthesizer.h: cubic interpolation now works in
638     24bit mode too. Faster method to read 24bit words on little
639     endian machines (x86): replaced 3 byte reads + shifts with a 1
640     unaligned 32bit read and shift
641     - experimental support for MS Windows (MIDI input via MME, AUDIO
642     output via ASIO)
643     - made handling of SIGINT signal (Ctrl-C) a bit more robust
644 iliev 1541 - support for monitoring the total number of active disk streams
645     (new LSCP commands: GET TOTAL_STREAM_COUNT,
646     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
647 persson 1455
648 senoner 1500 * AUDIO driver:
649 persson 1534 - added Windows ASIO low latency audio driver
650 senoner 1500
651 senoner 1485 * MIDI driver:
652 schoenebeck 1495 - added MME Windows MIDI driver
653 senoner 1485
654 schoenebeck 1471 * LSCP server:
655     - added support for Windows style path / filenames, however with
656     forward slash path separators instead of backslash
657     (i.e. "C:/foo/bar.gig")
658 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
659     apostrophes as well
660 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
661     "LIST FILE INSTRUMENTS <file>" and
662     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
663     about an arbitrary instrument file on the system where the sampler is
664     running on
665 schoenebeck 1471
666 schoenebeck 1424 Version 0.5.0 (15 October 2007)
667 schoenebeck 947
668 schoenebeck 1065 * packaging changes:
669 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
670     API header files anymore
671 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
672     the Doxygen API documentation (explicitly listed in Doxyfile.in)
673 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
674     capable to execute our autoconf environment, thus no need anymore
675     to maintain the compile time configuration file (osx/version.h) for
676     OSX manually (patch by Toshi Nagata)
677 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
678     parameters
679 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
680     C++ API header files, all implementation internal global definitions
681     are now in global_private.h
682     - atomic.h is not exposed to the C++ API anymore
683     - no need to include config.h anymore for using LS's API header files
684     - fixed warnings in API doc generation
685 schoenebeck 1065
686 schoenebeck 947 * general changes:
687     - replaced the old, confusing MIDI program change mechanism by a
688     flexible MIDI instrument mapper which allows to map arbitrary
689 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
690 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
691     loaded on the respective channel when such MIDI program change
692     messages arrive, beside that, each entry allows to define a life-time
693     strategy for the instrument, so the user can define whether the
694     instrument should i.e. be permanently loaded (to be able to switch
695     quickly among sounds) or i.e. loaded just on demand when the
696     respective program change arrives (to safe RAM space), as well as a
697     global volume factor for each entry, so the user can adjust the volume
698     dynamic of his mapped instrument collection without having to modify
699 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
700     MIDI instrument maps and assign each sampler channel individually
701     a certain map, so that i.e. separation of normal instruments and
702     drumkits is possible
703 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
704     MIDI instrument maps, MIDI instruments, FX sends, global volume.
705 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
706     due to a constant size RingBuffer FIFO which is now replaced by a
707     dynamic (unlimited) size std::list FIFO
708 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
709     output channels for being processed by external effect processors
710     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
711     controllers
712 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
713 iliev 1130 - Implemented new, improved notification system
714 schoenebeck 1149 - fixed compilation errors regarding OSX
715     (patch by Toshi Nagata)
716 iliev 1161 - implemented instruments database
717 iliev 1345 - added support for escape sequences to the instruments database
718 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
719     within the sampler's process (by using instrument editor plugins),
720     you'll notice the new "Registered instrument editors:" message on
721 schoenebeck 1407 startup, added a new LSCP command:
722     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
723 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
724     given sampler channel, the plugin path can be overridden at compile
725     time with ./configure --enable-plugin-dir=/some/dir
726 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
727     in the sampler's process to safely edit instruments while playing
728     without a crash (hopefully) by either suspending single regions
729     wherever possible or if unavoidable whole engine(s)
730 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
731     policy and priority on thread level, set a minimum stack size for
732     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
733     threads simply inherited properties of starting thread instead of
734     setting their own policy and priority
735 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
736     main process did not wait for the stack trace process to finish
737     its output
738 persson 1248 - fixed some minor memory leaks
739 schoenebeck 1259 - reenabled assembly features support, at the moment only for
740     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
741 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
742     register, to avoid relocations in the text segment at runtime)
743 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
744 schoenebeck 947
745     * MIDI driver:
746     - dispatch bank select (MSB and LSB) messages
747    
748 schoenebeck 1049 * audio driver:
749     - the ALSA audio output driver parameters now reflect the correct
750     parameter value ranges for the respective selected sound card
751     (patch by Till Wimmer, a bit fixed and extended)
752    
753 persson 951 * Gigasampler format engine:
754     - if a filter is used and EG2 finishes before EG1, let the voice
755     die when EG2 has finished (this fixes a problem with clicks and
756     voice starvation for some gigs)
757 persson 1038 - playback is no longer disabled during instrument loading
758     - all notes playing on a channel that changes its instrument keep
759     playing with the old instrument until they get a note off
760     command
761 persson 1039 - EG fix: a release value of zero could cause noises or crash
762 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
763 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
764     above max sustain level, which means that there is a decay phase
765     even if sustain is 100%
766 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
767     noises or crashes
768 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
769 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
770     supplied to the configure script (fixes #46)
771 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
772     instead of a fix value
773 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
774     127 (solo mode) only kill voices if the respective mode really
775     changed
776 persson 951
777 schoenebeck 1244 * LSCP server:
778     - fixed compile time error for old Bison versions
779     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
780 schoenebeck 1245 - parser now supports extended ASCII character set
781     (up to ASCII code 255, i.e. includes now umlauts and accents)
782     - filename arguments in LSCP commands now allow to use escape
783     sequences, that is directly literal as one of: \', \", \\, \n, \r,
784     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
785     code value like \xf2) (fixes bug #24)
786 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
787     least one of their text-based parameters (i.e. name, description):
788     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
789     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
790     "SET DB_INSTRUMENT_DIRECTORY NAME",
791     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
792     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
793     "FIND DB_INSTRUMENT_DIRECTORIES"
794 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
795     occured, the unexpected character and the actually expected, possible
796     character(s), the latter only if less than 5 possibilities)
797 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
798     settings
799 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
800     of strings were treated as being one string containing commas
801     (fixes #57)
802 schoenebeck 1244
803 iliev 959 * Bug fixes:
804     - fixed crash occurring on certain LSCP scripts (Bug 39)
805 persson 1038 - another thread safety fix for lscp "load engine" and "set
806     channel audio output device"
807 iliev 1283 - fixed a crash which occurs when reassigning the same engine
808     on a sampler channel with connected MIDI device
809 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
810     device connected to a sampler channel to number less then or equal
811     to the index of the port to which the sampler channel is connected.
812 iliev 1296 - The previous bindings were not been disconnected when altering
813     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
814     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
815 iliev 1297 - The active stream/voice count statistic was incorrect.
816 iliev 1298 - notification events were not been sent for some sampler
817     channel changes
818 iliev 1305 - added default min and max values to restrict the number of allowed
819     audio output channels and MIDI input ports
820 iliev 1306 - the connection to the PCM interface is now closed when destroying
821     an audio output device
822 schoenebeck 1332 - files with slash in their path or filename could not be loaded
823 iliev 959
824 schoenebeck 1221 * test cases:
825     - updated and fixed (haven't been touched in a while)
826    
827 schoenebeck 937 Version 0.4.0 (24 November 2006)
828 persson 696
829 schoenebeck 697 * packaging changes:
830 capela 868 - changed deprecated copyright attribute to license; added ldconfig
831     to post-(un)install steps; added devel package for liblinuxsampler;
832     to linuxsampler.spec (RPM)
833 schoenebeck 697 - install necessary development header files for allowing 3rd party
834     applications to link against liblinuxsampler
835     - liblinuxsampler's API documentation can be generated with 'make docs'
836     (Doxygen required)
837 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
838     implementation (currently either an integer math solution or a
839     di-harmonic approximation), automatic detection can be overriden
840     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
841     configure script argument though (mandatory for cross-compilation)
842 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
843     provided some on his own (as CXXFLAGS)
844 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
845     messages
846 schoenebeck 852 - added compile time options to allow disabling the various audio and
847     MIDI drivers
848 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
849     (patch by Ebrahim Mayat)
850 schoenebeck 697
851 persson 696 * Gigasampler format engine:
852 schoenebeck 738 - extensive synthesis optimization
853     (reimplementation of EGs and LFO(s), removed synthesis parameter
854     prerendering and the synthesis parameter matrix in general, splitting
855     each audio fragment into subfragments now where each subfragment uses
856 persson 830 constant pitch and filter coefficients. The volume coefficient is
857     linearly interpolated inside a subfragment, unless
858     --disable-interpolate-volume is set.)
859 persson 696 - fine tuning of the EG modulation parameters
860 persson 729 - improved filter cutoff calculation by adding support for the
861     following gig parameters: Cutoff freq (used when no cutoff
862     controller is defined), Control invert, Minimum cutoff, Velocity
863 persson 791 curve and Velocity range. The keyboard tracking now scales
864     cutoff frequency instead of resonance.
865 persson 877 - added support for gig parameter Resonance.
866 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
867 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
868     which can be overridden with --enable-global-attenuation
869 persson 783 - EG fixes: made the length of "attack hold" stage more
870     accurate. Release stage can now start before attack stage
871 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
872     time now has a minimal value to prevent clicks.
873 persson 799 - fixed pitch changes larger than one octave
874 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
875     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
876     all modes can be altered via standard GM messages, that is CC5 for
877     altering portamento time, CC65 for enabling / disabling portamento
878     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
879 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
880     parameter) and crossfade
881 persson 831 - added support for the "attenuation controller threshold" gig
882     parameter
883 persson 832 - added smoothing of volume changes caused by control change
884     messages
885 persson 865 - sample loop parameters are now taken from the DimensionRegion
886     instead of the wave chunk
887     - fixed keyswitching for v3 gigs with a number of keyswitch splits
888     not equal to a power of two
889 persson 877 - reimplementation of the filter algorithm. The new filter is more
890     accurate and supports all gig filter types, including bandreject
891     and lowpass turbo.
892 persson 903 - real support for 24 bit samples - samples are not truncated to
893     16 bits anymore
894     - support for aftertouch (channel pressure, not polyphonic
895     aftertouch)
896 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
897     amplifying from 0)
898 persson 696
899 schoenebeck 711 * LSCP server:
900     - fixed application exit on broken pipe error (fixes bug #20)
901 iliev 793 - fixed the notification messages delay due to lack of
902     network activity (fixes bug #26)
903 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
904     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
905 schoenebeck 711
906 schoenebeck 838 * audio driver:
907     - added aRts audio output driver (by no means RT safe)
908    
909 schoenebeck 775 * MIDI driver:
910     - fixed legacy sysex code which caused dispatching of MIDI SysEx
911     messages several times instead of once
912 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
913     for events (i.e. for offline rendering based MIDI drivers)
914 persson 922 - added checks for bad MIDI data
915 schoenebeck 775
916 schoenebeck 900 * linuxsampler application:
917     - show available sampler engine types on startup
918    
919 schoenebeck 705 * general changes:
920     - support for muting sampler channels and solo mode of the same, two new
921     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
922     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
923     introduced for this, the behavior is the same like on a mixer console
924 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
925     --enable-process-muted-channels which can be used to enable the
926     processing of muted channels.
927 iliev 777 - support for sostenuto pedal
928 iliev 779 - support for monitoring the total number of active voices
929 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
930     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
931 persson 835 - fixed some memory management errors
932 persson 841 - fixed some concurrency problems that could lead to crashes when
933     LSCP commands were executed
934 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
935     sampler channel (fixes bug #36)
936 schoenebeck 705
937 schoenebeck 692 Version 0.3.3 (15 July 2005)
938 schoenebeck 686
939     * packaging changes:
940     - fixed compilation with gcc 4.0
941    
942 schoenebeck 687 * Gigasampler format engine:
943     - LFO preprocessing was performed even though the respective LFO was
944     disabled by the instrument patch (minor efficiency fix)
945 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
946     for volume ramp downs in the same fragment (needed for current voice
947     stealing implementation) then simply inform the user with a warning
948     about possible click sounds and reduce the volume ramp down
949     appropriately instead of cancelling the audio device connection
950 schoenebeck 687
951 schoenebeck 677 Version 0.3.2 (24 June 2005)
952 schoenebeck 609
953     * packaging changes:
954     - updated autotools build files to compile on OS X
955     (conditional compilation of CoreMIDI and MidiShare drivers)
956 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
957     './configure --disable-asm' (definitely not recommended)
958 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
959     - require automake (>= 1.5) for 'make -f Makefile.cvs'
960     (due to 'dist-bzip2' automake option)
961 schoenebeck 649
962     * Gigasampler format engine:
963     - support for the gig parameters for "release velocity response" curves
964     - fine tuning of the EGADSR envelope
965     - volume of release triggered samples now depends on note-on velocity,
966     note length and gig parameter "release trigger decay" instead of
967     note-off velocity.
968 schoenebeck 663 - revised voice stealing
969     (fixes crash and endless loop caused by voice stealing)
970 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
971 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
972     instead of when the respective voice is actually launched
973     (fixes undefined behavior if stolen voices belonged to a key group -
974     this case was followed by a "killed voice survived" error message)
975 schoenebeck 669 - fixed minor issue with null/silence samples
976     (those stole voices even though they don't need a voice at all which
977     resulted in "voice stealing didn't work out" messages)
978 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
979     instrument or audio output device change
980 schoenebeck 654
981 schoenebeck 620 * LSCP server:
982 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
983 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
984 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
985 schoenebeck 609
986 schoenebeck 668 * linuxsampler application:
987     - added command line parameters --lscp-addr and --lscp-port to override
988     default IP address and port of LSCP server
989    
990 schoenebeck 579 Version 0.3.1 (24 May 2005)
991    
992     * initial release
