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

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
12 persson 2185 - made --enable-pthread-testcancel default on Mac OS X

14     directories are separate
15 persson 2203 - Mac OS X: made it possible to specify plugin installation dir to
16     configure

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

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

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

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

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

401 schoenebeck 1599
402 schoenebeck 1639 * packaging changes:
403     - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,

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

465     - removed the nonsense audio channel constraint (which was hard coded to
466     max. 100 audio channels) for most audio drivers
467 schoenebeck 1604 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
468     opposed to the LSCP specs

474 persson 1748 jack_client_new
475 iliev 1829 - added (experimental) CoreAudio driver
476 persson 1888 - applied old fixes to the ASIO driver that were included in the
477     previous binary release but accidentally never committed to CVS
478     (fixes #117)
479 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
480     win64)
481 persson 1895 - VST: added support for sample rate and buffer size changes
482     - VST: close editor (Fantasia) when the VST is removed

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

510     to the instruments database
511 iliev 1727 - added support for handling lost files in the instruments database
512 iliev 1781 - Implemented option for adding instruments in separate directories
513     in the instruments database
514     (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
515 persson 1908 - work-around for missing fnmatch function on Windows to make
516     instrument database compilable
517 schoenebeck 1930 - added instrument database support on Windows
518     works with both standalone mode and VST plugin.
519     the instruments DB file is located in
520     %USERPROFILE%\.linuxsampler\instruments.db which allows different
521     databases for each windows user
522     if no DB is present it automatically creates the .linuxsampler subdir
523     and then creates an empty DB
524 persson 1943 - fixed recursive import, which was broken on Windows
525 iliev 1603
526 persson 1644 * Gigasampler format engine:
527     - fixed a memory leak that could happen when a channel was deleted

529 persson 1646 - made it possible to load an instrument even if the audio thread
530     isn't running
531 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
532     enough for piano gigs with pedal noise samples
533 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
534     respective FX send MIDI controller was used
535 schoenebeck 1724 - added support for GM global device volume SysEx message
536 schoenebeck 1762 (can be selected at compile time to either apply globally to the
537     whole sampler [default] or only to the sampler channels that are
538     connected to the respective MIDI input port the SysEx message arrived
539     on)
540 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
541     sometimes wrongly killed in the same buffer, causing no sound to
542     be played
543 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
544     which is usally used to switch a part between chromatic sounds and
545     drumkit sounds (as opposed to their common default setting of MIDI
546     part 10 being a drumkit part and all other ones chromatic parts), in
547     LS however one can switch between the first 16 MIDI instrument maps
548     defined for the sampler
549 persson 1764 - made it possible to create multiple sample channels even if the
550     audio thread isn't running
551 persson 1844 - fixed crash when removing channel with active voices (#116)
552 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
553     un-cache the respective sample if it's really not used by any
554     sampler engine anymore
555     - re-cache samples in case they were changed by an instrument editor,
556     e.g. when a sample was added while playing (#82)
557 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
558     same time stamp as the voice's note-on event and occured both in the
559     same audio fragment cycle (fixes bug #112)
560 persson 1858 - added support for the "fine tune" and "pitch bend range"
561     instrument-level gig parameters
562     - fixed minor artifacts in pitch bend handling
563 schoenebeck 1860 - added support for GS Reset SysEx message
564 persson 1862 - allow gig files to use unlimited downward pitch shifting
565     - added a limit check for upward pitch shifting
566 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
567     note was silent
568 persson 1923 - fixed crash happening when a pitch bend event arrived at the
569     same time a new instrument was loading
570 persson 1644
571 schoenebeck 1687 * LSCP server:
572     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
573     react on MIDI data arriving on certain sampler channels (so far only
574     Note-On and Note-Off events are sent via this LSCP event)
575 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
576     react on MIDI data arriving on certain MIDI input devices (so far only
577     Note-On and Note-Off events are sent via this LSCP event)
578 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
579     SET DB_INSTRUMENT FILE_PATH
580 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
581     frontends to send MIDI messages to specific sampler channel
582     - added two additional fields to GET FILE INSTRUMENT INFO command -
583     KEY_BINDINGS and KEYSWITCH_BINDINGS
584 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
585     was incorrect
586 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
587 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
588     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
589     be triggered respectively
590     - added new LSCP command "SET STREAMS" to globally alter the maximum
591     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
592     which will be triggered respectively
593 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
594     a gigedit file dialog is opened)
595 iliev 1848 - close all connections when LSCPServer is deleted
596 iliev 1882 - hard close of all sockets on exit
597 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
598     driver
599 schoenebeck 1687
600 iliev 1761 * Bug fixes:
601     - fixed a crash which occurs when removing a sampler channel waiting
602     to start instrument loading after another channel
603 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
604     instrument loading in progress (bug #113)
605 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
606     instrument with PERSISTENT load mode
607 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
608     - fixed memory leaks when issuing the following LSCP commands:
609     GET AUDIO_OUTPUT_DRIVER INFO
610     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
611     GET MIDI_INPUT_DRIVER INFO
612     GET MIDI_INPUT_DRIVER_PARAMETER INFO
613     - fixed possible compilation error when sqlite is not present
614 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
615 iliev 1847 - fixed crash when changing the audio output device of a sampler
616     channel with loaded instrument and start playing notes
617 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
618 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
619     PowerPC, which probably could cause crashes on that platform
620 persson 1889 - fixed a memory management error which could cause a crash when a
621     plugin was unloaded
622 persson 1896 - bugfix: two private structs had the same name, which could cause
623     problems if the linker chose the wrong constructor
624 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
625     Windows
626 iliev 1761
627    
628 schoenebeck 1560 Version 0.5.1 (6 December 2007)
629 schoenebeck 1454
630     * packaging changes:
631     - added autoconf checks for pthread library
632     - added autoconf check for pthread bug found on certain NPTL-enabled
633     glibc versions (see Gentoo bug report #194076)
634 senoner 1502 - added autoconf checks for MS Windows
635 schoenebeck 1454
636 persson 1455 * general changes:
637     - bugfix: the thread used by an editor plugin didn't die when the
638     editor closed
639 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
640     out all the space. operator--() did not apply size_mask after
641     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
642     order to avoid problems with the _NonVolatileReader functions.
643     - bugfix: Stream.h: added a missing divide by BytesPerSample in
644     GetWriteSpace(). Since this function is currently only used in
645     the stream's qsort() compare function, it didn't trigger any
646     bugs.
647     - Resampler.h, Synthesizer.h: cubic interpolation now works in
648     24bit mode too. Faster method to read 24bit words on little
649     endian machines (x86): replaced 3 byte reads + shifts with a 1
650     unaligned 32bit read and shift
651     - experimental support for MS Windows (MIDI input via MME, AUDIO
652     output via ASIO)
653     - made handling of SIGINT signal (Ctrl-C) a bit more robust
654 iliev 1541 - support for monitoring the total number of active disk streams
655     (new LSCP commands: GET TOTAL_STREAM_COUNT,
656     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
657 persson 1455
658 senoner 1500 * AUDIO driver:
659 persson 1534 - added Windows ASIO low latency audio driver
660 senoner 1500
661 senoner 1485 * MIDI driver:
662 schoenebeck 1495 - added MME Windows MIDI driver
663 senoner 1485
664 schoenebeck 1471 * LSCP server:
665     - added support for Windows style path / filenames, however with
666     forward slash path separators instead of backslash
667     (i.e. "C:/foo/bar.gig")
668 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
669     apostrophes as well
670 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
671     "LIST FILE INSTRUMENTS <file>" and
672     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
673     about an arbitrary instrument file on the system where the sampler is
674     running on
675 schoenebeck 1471
676 schoenebeck 1424 Version 0.5.0 (15 October 2007)
677 schoenebeck 947
678 schoenebeck 1065 * packaging changes:
679 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
680     API header files anymore
681 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
682     the Doxygen API documentation (explicitly listed in Doxyfile.in)
683 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
684     capable to execute our autoconf environment, thus no need anymore
685     to maintain the compile time configuration file (osx/version.h) for
686     OSX manually (patch by Toshi Nagata)
687 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
688     parameters
689 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
690     C++ API header files, all implementation internal global definitions
691     are now in global_private.h
692     - atomic.h is not exposed to the C++ API anymore
693     - no need to include config.h anymore for using LS's API header files
694     - fixed warnings in API doc generation
695 schoenebeck 1065
696 schoenebeck 947 * general changes:
697     - replaced the old, confusing MIDI program change mechanism by a
698     flexible MIDI instrument mapper which allows to map arbitrary
699 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
700 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
701     loaded on the respective channel when such MIDI program change
702     messages arrive, beside that, each entry allows to define a life-time
703     strategy for the instrument, so the user can define whether the
704     instrument should i.e. be permanently loaded (to be able to switch
705     quickly among sounds) or i.e. loaded just on demand when the
706     respective program change arrives (to safe RAM space), as well as a
707     global volume factor for each entry, so the user can adjust the volume
708     dynamic of his mapped instrument collection without having to modify
709 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
710     MIDI instrument maps and assign each sampler channel individually
711     a certain map, so that i.e. separation of normal instruments and
712     drumkits is possible
713 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
714     MIDI instrument maps, MIDI instruments, FX sends, global volume.
715 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
716     due to a constant size RingBuffer FIFO which is now replaced by a
717     dynamic (unlimited) size std::list FIFO
718 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
719     output channels for being processed by external effect processors
720     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
721     controllers
722 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
723 iliev 1130 - Implemented new, improved notification system
724 schoenebeck 1149 - fixed compilation errors regarding OSX
725     (patch by Toshi Nagata)
726 iliev 1161 - implemented instruments database
727 iliev 1345 - added support for escape sequences to the instruments database
728 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
729     within the sampler's process (by using instrument editor plugins),
730     you'll notice the new "Registered instrument editors:" message on
731 schoenebeck 1407 startup, added a new LSCP command:
732     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
733 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
734     given sampler channel, the plugin path can be overridden at compile
735     time with ./configure --enable-plugin-dir=/some/dir
736 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
737     in the sampler's process to safely edit instruments while playing
738     without a crash (hopefully) by either suspending single regions
739     wherever possible or if unavoidable whole engine(s)
740 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
741     policy and priority on thread level, set a minimum stack size for
742     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
743     threads simply inherited properties of starting thread instead of
744     setting their own policy and priority
745 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
746     main process did not wait for the stack trace process to finish
747     its output
748 persson 1248 - fixed some minor memory leaks
749 schoenebeck 1259 - reenabled assembly features support, at the moment only for
750     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
751 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
752     register, to avoid relocations in the text segment at runtime)
753 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
754 schoenebeck 947
755     * MIDI driver:
756     - dispatch bank select (MSB and LSB) messages
757    
758 schoenebeck 1049 * audio driver:
759     - the ALSA audio output driver parameters now reflect the correct
760     parameter value ranges for the respective selected sound card
761     (patch by Till Wimmer, a bit fixed and extended)
762    
763 persson 951 * Gigasampler format engine:
764     - if a filter is used and EG2 finishes before EG1, let the voice
765     die when EG2 has finished (this fixes a problem with clicks and
766     voice starvation for some gigs)
767 persson 1038 - playback is no longer disabled during instrument loading
768     - all notes playing on a channel that changes its instrument keep
769     playing with the old instrument until they get a note off
770     command
771 persson 1039 - EG fix: a release value of zero could cause noises or crash
772 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
773 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
774     above max sustain level, which means that there is a decay phase
775     even if sustain is 100%
776 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
777     noises or crashes
778 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
779 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
780     supplied to the configure script (fixes #46)
781 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
782     instead of a fix value
783 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
784     127 (solo mode) only kill voices if the respective mode really
785     changed
786 persson 951
787 schoenebeck 1244 * LSCP server:
788     - fixed compile time error for old Bison versions
789     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
790 schoenebeck 1245 - parser now supports extended ASCII character set
791     (up to ASCII code 255, i.e. includes now umlauts and accents)
792     - filename arguments in LSCP commands now allow to use escape
793     sequences, that is directly literal as one of: \', \", \\, \n, \r,
794     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
795     code value like \xf2) (fixes bug #24)
796 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
797     least one of their text-based parameters (i.e. name, description):
798     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
799     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
800     "SET DB_INSTRUMENT_DIRECTORY NAME",
801     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
802     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
803     "FIND DB_INSTRUMENT_DIRECTORIES"
804 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
805     occured, the unexpected character and the actually expected, possible
806     character(s), the latter only if less than 5 possibilities)
807 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
808     settings
809 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
810     of strings were treated as being one string containing commas
811     (fixes #57)
812 schoenebeck 1244
813 iliev 959 * Bug fixes:
814     - fixed crash occurring on certain LSCP scripts (Bug 39)
815 persson 1038 - another thread safety fix for lscp "load engine" and "set
816     channel audio output device"
817 iliev 1283 - fixed a crash which occurs when reassigning the same engine
818     on a sampler channel with connected MIDI device
819 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
820     device connected to a sampler channel to number less then or equal
821     to the index of the port to which the sampler channel is connected.
822 iliev 1296 - The previous bindings were not been disconnected when altering
823     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
824     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
825 iliev 1297 - The active stream/voice count statistic was incorrect.
826 iliev 1298 - notification events were not been sent for some sampler
827     channel changes
828 iliev 1305 - added default min and max values to restrict the number of allowed
829     audio output channels and MIDI input ports
830 iliev 1306 - the connection to the PCM interface is now closed when destroying
831     an audio output device
832 schoenebeck 1332 - files with slash in their path or filename could not be loaded
833 iliev 959
834 schoenebeck 1221 * test cases:
835     - updated and fixed (haven't been touched in a while)
836    
837 schoenebeck 937 Version 0.4.0 (24 November 2006)
838 persson 696
839 schoenebeck 697 * packaging changes:
840 capela 868 - changed deprecated copyright attribute to license; added ldconfig
841     to post-(un)install steps; added devel package for liblinuxsampler;
842     to linuxsampler.spec (RPM)
843 schoenebeck 697 - install necessary development header files for allowing 3rd party
844     applications to link against liblinuxsampler
845     - liblinuxsampler's API documentation can be generated with 'make docs'
846     (Doxygen required)
847 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
848     implementation (currently either an integer math solution or a
849     di-harmonic approximation), automatic detection can be overriden
850     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
851     configure script argument though (mandatory for cross-compilation)
852 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
853     provided some on his own (as CXXFLAGS)
854 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
855     messages
856 schoenebeck 852 - added compile time options to allow disabling the various audio and
857     MIDI drivers
858 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
859     (patch by Ebrahim Mayat)
860 schoenebeck 697
861 persson 696 * Gigasampler format engine:
862 schoenebeck 738 - extensive synthesis optimization
863     (reimplementation of EGs and LFO(s), removed synthesis parameter
864     prerendering and the synthesis parameter matrix in general, splitting
865     each audio fragment into subfragments now where each subfragment uses
866 persson 830 constant pitch and filter coefficients. The volume coefficient is
867     linearly interpolated inside a subfragment, unless
868     --disable-interpolate-volume is set.)
869 persson 696 - fine tuning of the EG modulation parameters
870 persson 729 - improved filter cutoff calculation by adding support for the
871     following gig parameters: Cutoff freq (used when no cutoff
872     controller is defined), Control invert, Minimum cutoff, Velocity
873 persson 791 curve and Velocity range. The keyboard tracking now scales
874     cutoff frequency instead of resonance.
875 persson 877 - added support for gig parameter Resonance.
876 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
877 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
878     which can be overridden with --enable-global-attenuation
879 persson 783 - EG fixes: made the length of "attack hold" stage more
880     accurate. Release stage can now start before attack stage
881 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
882     time now has a minimal value to prevent clicks.
883 persson 799 - fixed pitch changes larger than one octave
884 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
885     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
886     all modes can be altered via standard GM messages, that is CC5 for
887     altering portamento time, CC65 for enabling / disabling portamento
888     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
889 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
890     parameter) and crossfade
891 persson 831 - added support for the "attenuation controller threshold" gig
892     parameter
893 persson 832 - added smoothing of volume changes caused by control change
894     messages
895 persson 865 - sample loop parameters are now taken from the DimensionRegion
896     instead of the wave chunk
897     - fixed keyswitching for v3 gigs with a number of keyswitch splits
898     not equal to a power of two
899 persson 877 - reimplementation of the filter algorithm. The new filter is more
900     accurate and supports all gig filter types, including bandreject
901     and lowpass turbo.
902 persson 903 - real support for 24 bit samples - samples are not truncated to
903     16 bits anymore
904     - support for aftertouch (channel pressure, not polyphonic
905     aftertouch)
906 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
907     amplifying from 0)
908 persson 696
909 schoenebeck 711 * LSCP server:
910     - fixed application exit on broken pipe error (fixes bug #20)
911 iliev 793 - fixed the notification messages delay due to lack of
912     network activity (fixes bug #26)
913 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
914     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
915 schoenebeck 711
916 schoenebeck 838 * audio driver:
917     - added aRts audio output driver (by no means RT safe)
918    
919 schoenebeck 775 * MIDI driver:
920     - fixed legacy sysex code which caused dispatching of MIDI SysEx
921     messages several times instead of once
922 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
923     for events (i.e. for offline rendering based MIDI drivers)
924 persson 922 - added checks for bad MIDI data
925 schoenebeck 775
926 schoenebeck 900 * linuxsampler application:
927     - show available sampler engine types on startup
928    
929 schoenebeck 705 * general changes:
930     - support for muting sampler channels and solo mode of the same, two new
931     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
932     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
933     introduced for this, the behavior is the same like on a mixer console
934 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
935     --enable-process-muted-channels which can be used to enable the
936     processing of muted channels.
937 iliev 777 - support for sostenuto pedal
938 iliev 779 - support for monitoring the total number of active voices
939 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
940     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
941 persson 835 - fixed some memory management errors
942 persson 841 - fixed some concurrency problems that could lead to crashes when
943     LSCP commands were executed
944 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
945     sampler channel (fixes bug #36)
946 schoenebeck 705
947 schoenebeck 692 Version 0.3.3 (15 July 2005)
948 schoenebeck 686
949     * packaging changes:
950     - fixed compilation with gcc 4.0
951    
952 schoenebeck 687 * Gigasampler format engine:
953     - LFO preprocessing was performed even though the respective LFO was
954     disabled by the instrument patch (minor efficiency fix)
955 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
956     for volume ramp downs in the same fragment (needed for current voice
957     stealing implementation) then simply inform the user with a warning
958     about possible click sounds and reduce the volume ramp down
959     appropriately instead of cancelling the audio device connection
960 schoenebeck 687
961 schoenebeck 677 Version 0.3.2 (24 June 2005)
962 schoenebeck 609
963     * packaging changes:
964     - updated autotools build files to compile on OS X
965     (conditional compilation of CoreMIDI and MidiShare drivers)
966 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
967     './configure --disable-asm' (definitely not recommended)
968 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
969     - require automake (>= 1.5) for 'make -f Makefile.cvs'
970     (due to 'dist-bzip2' automake option)
971 schoenebeck 649
972     * Gigasampler format engine:
973     - support for the gig parameters for "release velocity response" curves
974     - fine tuning of the EGADSR envelope
975     - volume of release triggered samples now depends on note-on velocity,
976     note length and gig parameter "release trigger decay" instead of
977     note-off velocity.
978 schoenebeck 663 - revised voice stealing
979     (fixes crash and endless loop caused by voice stealing)
980 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
981 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
982     instead of when the respective voice is actually launched
983     (fixes undefined behavior if stolen voices belonged to a key group -
984     this case was followed by a "killed voice survived" error message)
985 schoenebeck 669 - fixed minor issue with null/silence samples
986     (those stole voices even though they don't need a voice at all which
987     resulted in "voice stealing didn't work out" messages)
988 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
989     instrument or audio output device change
990 schoenebeck 654
991 schoenebeck 620 * LSCP server:
992 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
993 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
994 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
995 schoenebeck 609
996 schoenebeck 668 * linuxsampler application:
997     - added command line parameters --lscp-addr and --lscp-port to override
998     default IP address and port of LSCP server
999    
1000 schoenebeck 579 Version 0.3.1 (24 May 2005)
1001    
1002     * initial release
