* LSCP Server: Fixed bug in LSCP grammar definition which caused a
  statement like "GET SERVER INFOasdf\n" to be accepted as valid
  statement (was so far practically irrelevant, however it caused
  problems with the following new LSCP shell's auto completion
  feature).
* LSCP shell: improvement of auto completion feature, which now
  not only resolves the next LSCP command token, but the longest,
  unique sequence of LSCP commands expected next. Accordingly it
  can now auto complete an entire line.
* Bumped version (1.0.0.svn33).

40 persson 2382
41 persson 2086 * general changes:
42 iliev 2012 - Refactoring: moved the independent code from
43     the Gigasampler format engine to base classes
44 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
45     respective profiling code is currently broken
46 schoenebeck 2053 - Introduced support for optional environment variable
47     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
48     where the sampler shall look for instrument editor plugins
49     (patch by Luis Garrido, slightly modified).
50 schoenebeck 2121 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
51     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
52     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
53     note (in this implementation of the sampler its simply hard routed to
54     the 1st effect send of the sampler channel, no matter what the actual
55     effect type is)
56     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
57     note (in this implementation of the sampler its simply hard routed to
58     the 2nd effect send of the sampler channel, no matter what the actual
59     effect type is)
60 schoenebeck 2124 - implemented support for internal LADSPA effects
61 schoenebeck 2140 - raised limit of program change queue from 100 to 512
62     (as suggested by Alex Stone)
63 iliev 2223 - implemented sine LFO, pulse LFO and saw LFO
64 iliev 2296 - experimental support for per voice equalization
65 iliev 2306 - added command line option --exec-after-init
66 schoenebeck 2330 - Introduced new C++ API method:
67     EngineChannel::InstrumentFileName(int index)
68     allowing to retrieve the whole list of files used for the loaded
69     instrument on an engine channel (a.k.a. part). Some GigaStudio
70     instruments for example are splitted over several files like
71     "Foo.gig", "Foo.gx01", "Foo.gx02", ...
72 schoenebeck 2375 - Added new C++ API method Sampler::GetGlobalMaxVoices().
73     - Added new C++ API method Sampler::GetGlobalMaxStreams().
74     - Added new C++ API method Sampler::SetGlobalMaxVoices().
75     - Added new C++ API method Sampler::SetGlobalMaxStreams().
76 schoenebeck 2377 - Various "const" and "restrict" optimizations.
77 persson 2382 - all engines: add pan CC value to instrument pan parameter before
78     applying panning, instead of using two separate pan functions in
79     series (#182)
80 persson 2427 - added a lock guard class for exception safe mutex handling and
81     used it everywhere appropriate
82 schoenebeck 2448 - Immediately apply scale tuning changes to active voices.
83     - Exposed scale tuning to C++ API (along to the already existing standard
84     SysEx way).
85 persson 2452 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
86     and broken for ppc64. (Seq_cst loads and stores are actually not
87     used in LS, so the bug wasn't noticable.)
88     - lsatomic.h: added ARMv7 support
89 schoenebeck 2500 - Added support for multiple MIDI input ports per sampler channel (and
90     added various new C++ methods for this new feature / design change, old
91     C++ API methods for managing SamplerChannel's MIDI inputs are now marked
92     as deprecated but are still there and should provide full behavior
93     backward compatibility).
94     - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
95     unsafe and caused compilation error with clang 2.x).
96 schoenebeck 2506 - Bugfix: only process the latest MIDI program change event.
97 schoenebeck 2515 - Introducing the LSCP shell, which provides convenient control of the
98     sampler from the command line by providing LSCP aware features.
99 schoenebeck 2521 - VirtualMidiDevice: Added support for program change.
100     - VirtualMidiDevice: Added support for bank select (MSB & LSB).
101     - VirtualMidiDevice: Added support for pitch bend.

108     key
109 persson 2382 - bugfix: pitch LFO controller "internal+aftertouch" was broken
110     - bugfix: filter keyboard tracking was broken
111     - filter performance fix (an unnecessary copy was made of the
112     filter parameters in each sub fragment)
113     - handle special case when pan parameter in gig file has max or
114     min value
115 schoenebeck 2396 - Exclusive Groups: don't ever stop voices of the same note,
116     doesn't sound naturally with a drumkit

311     - VST: fixed crashes on Linux Ardour and EnergyXT
312 persson 2354 - DSSI bugfix: it wasn't possible to change engine type. The MIDI

420     after MIDI/audio device creation failure
421 schoenebeck 2275 - When creating MIDI instrument map entries with "PERSISTENT" type, the

423     took the full preloading time and on 1st program change the respective
424     instrument was completely reloaded again.
425 persson 2277 - fixed handling of rapid bank select and program change messages
426     sent to the same sampler channel (patch from the Open Octave

448     (fixes #208)
449 schoenebeck 2523 - Fixed bug in LSCP grammar definition which caused a statement like
450     "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
451     practically irrelevant, however it caused problems with the new LSCP
452     shell's auto completion feature).

504     stacktrace mechanism seems to be broken on most systems at the moment)
505 schoenebeck 1868 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
506     a pointer to the launched InstrumentEditor object
507 schoenebeck 1876 - added optional 3rd party user data parameter for following

530 iliev 1829 - added (experimental) CoreAudio driver
531 persson 1888 - applied old fixes to the ASIO driver that were included in the
532     previous binary release but accidentally never committed to CVS
533     (fixes #117)
534 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on

549     exception when getting parameters from a disconnected device
550 schoenebeck 1599
551 persson 1651 * MIDI driver:
552     - added JACK MIDI driver
553 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously

555     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
556 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,

571     instrument database compilable
572 schoenebeck 1930 - added instrument database support on Windows
573     works with both standalone mode and VST plugin.
574     the instruments DB file is located in
575     %USERPROFILE%\.linuxsampler\instruments.db which allows different
576     databases for each windows user
577     if no DB is present it automatically creates the .linuxsampler subdir
578     and then creates an empty DB
579 persson 1943 - fixed recursive import, which was broken on Windows
580 iliev 1603
581 persson 1644 * Gigasampler format engine:
582     - fixed a memory leak that could happen when a channel was deleted

584 persson 1646 - made it possible to load an instrument even if the audio thread
585     isn't running
586 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
587     enough for piano gigs with pedal noise samples
588 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
589     respective FX send MIDI controller was used
590 schoenebeck 1724 - added support for GM global device volume SysEx message
591 schoenebeck 1762 (can be selected at compile time to either apply globally to the
592     whole sampler [default] or only to the sampler channels that are
593     connected to the respective MIDI input port the SysEx message arrived
594     on)
595 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
596     sometimes wrongly killed in the same buffer, causing no sound to
597     be played
598 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
599     which is usally used to switch a part between chromatic sounds and
600     drumkit sounds (as opposed to their common default setting of MIDI
601     part 10 being a drumkit part and all other ones chromatic parts), in
602     LS however one can switch between the first 16 MIDI instrument maps
603     defined for the sampler
604 persson 1764 - made it possible to create multiple sample channels even if the
605     audio thread isn't running
606 persson 1844 - fixed crash when removing channel with active voices (#116)
607 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
608     un-cache the respective sample if it's really not used by any
609     sampler engine anymore
610     - re-cache samples in case they were changed by an instrument editor,
611     e.g. when a sample was added while playing (#82)
612 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
613     same time stamp as the voice's note-on event and occured both in the
614     same audio fragment cycle (fixes bug #112)
615 persson 1858 - added support for the "fine tune" and "pitch bend range"
616     instrument-level gig parameters
617     - fixed minor artifacts in pitch bend handling
618 schoenebeck 1860 - added support for GS Reset SysEx message
619 persson 1862 - allow gig files to use unlimited downward pitch shifting
620     - added a limit check for upward pitch shifting
621 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
622     note was silent
623 persson 1923 - fixed crash happening when a pitch bend event arrived at the
624     same time a new instrument was loading
625 persson 1644
626 schoenebeck 1687 * LSCP server:
627     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
628     react on MIDI data arriving on certain sampler channels (so far only
629     Note-On and Note-Off events are sent via this LSCP event)
630 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
631     react on MIDI data arriving on certain MIDI input devices (so far only
632     Note-On and Note-Off events are sent via this LSCP event)
633 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
634     SET DB_INSTRUMENT FILE_PATH

636     frontends to send MIDI messages to specific sampler channel
637     - added two additional fields to GET FILE INSTRUMENT INFO command -
638     KEY_BINDINGS and KEYSWITCH_BINDINGS
639 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
640     was incorrect
641 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
642 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
643     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
644     be triggered respectively
645     - added new LSCP command "SET STREAMS" to globally alter the maximum
646     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
647     which will be triggered respectively
648 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
649     a gigedit file dialog is opened)
650 iliev 1848 - close all connections when LSCPServer is deleted
651 iliev 1882 - hard close of all sockets on exit

670 iliev 1847 - fixed crash when changing the audio output device of a sampler
671     channel with loaded instrument and start playing notes
672 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
673 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
674     PowerPC, which probably could cause crashes on that platform
675 persson 1889 - fixed a memory management error which could cause a crash when a
676     plugin was unloaded

683 schoenebeck 1560 Version 0.5.1 (6 December 2007)
684 schoenebeck 1454
685     * packaging changes:
686     - added autoconf checks for pthread library
687     - added autoconf check for pthread bug found on certain NPTL-enabled
688     glibc versions (see Gentoo bug report #194076)
689 senoner 1502 - added autoconf checks for MS Windows
690 schoenebeck 1454
691 persson 1455 * general changes:
692     - bugfix: the thread used by an editor plugin didn't die when the
693     editor closed
694 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
695     out all the space. operator--() did not apply size_mask after
696     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
697     order to avoid problems with the _NonVolatileReader functions.
698     - bugfix: Stream.h: added a missing divide by BytesPerSample in
699     GetWriteSpace(). Since this function is currently only used in
700     the stream's qsort() compare function, it didn't trigger any
701     bugs.
702     - Resampler.h, Synthesizer.h: cubic interpolation now works in
703     24bit mode too. Faster method to read 24bit words on little
704     endian machines (x86): replaced 3 byte reads + shifts with a 1
705     unaligned 32bit read and shift
706     - experimental support for MS Windows (MIDI input via MME, AUDIO
707     output via ASIO)
708     - made handling of SIGINT signal (Ctrl-C) a bit more robust
709 iliev 1541 - support for monitoring the total number of active disk streams
710     (new LSCP commands: GET TOTAL_STREAM_COUNT,
711     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
712 persson 1455
713 senoner 1500 * AUDIO driver:
714 persson 1534 - added Windows ASIO low latency audio driver
715 senoner 1500
716 senoner 1485 * MIDI driver:
717 schoenebeck 1495 - added MME Windows MIDI driver
718 senoner 1485
719 schoenebeck 1471 * LSCP server:
720     - added support for Windows style path / filenames, however with
721     forward slash path separators instead of backslash
722     (i.e. "C:/foo/bar.gig")
723 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
724     apostrophes as well
725 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
726     "LIST FILE INSTRUMENTS <file>" and
727     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
728     about an arbitrary instrument file on the system where the sampler is
729     running on
730 schoenebeck 1471
731 schoenebeck 1424 Version 0.5.0 (15 October 2007)
732 schoenebeck 947
733 schoenebeck 1065 * packaging changes:
734 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
735     API header files anymore
736 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
737     the Doxygen API documentation (explicitly listed in Doxyfile.in)
738 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
739     capable to execute our autoconf environment, thus no need anymore
740     to maintain the compile time configuration file (osx/version.h) for
741     OSX manually (patch by Toshi Nagata)
742 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
743     parameters
744 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
745     C++ API header files, all implementation internal global definitions
746     are now in global_private.h
747     - atomic.h is not exposed to the C++ API anymore
748     - no need to include config.h anymore for using LS's API header files
749     - fixed warnings in API doc generation
750 schoenebeck 1065
751 schoenebeck 947 * general changes:
752     - replaced the old, confusing MIDI program change mechanism by a
753     flexible MIDI instrument mapper which allows to map arbitrary
754 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
755 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
756     loaded on the respective channel when such MIDI program change
757     messages arrive, beside that, each entry allows to define a life-time
758     strategy for the instrument, so the user can define whether the
759     instrument should i.e. be permanently loaded (to be able to switch
760     quickly among sounds) or i.e. loaded just on demand when the
761     respective program change arrives (to safe RAM space), as well as a
762     global volume factor for each entry, so the user can adjust the volume
763     dynamic of his mapped instrument collection without having to modify
764 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
765     MIDI instrument maps and assign each sampler channel individually
766     a certain map, so that i.e. separation of normal instruments and
767     drumkits is possible
768 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
769     MIDI instrument maps, MIDI instruments, FX sends, global volume.
770 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
771     due to a constant size RingBuffer FIFO which is now replaced by a
772     dynamic (unlimited) size std::list FIFO
773 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
774     output channels for being processed by external effect processors
775     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
776     controllers
777 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
778 iliev 1130 - Implemented new, improved notification system
779 schoenebeck 1149 - fixed compilation errors regarding OSX
780     (patch by Toshi Nagata)
781 iliev 1161 - implemented instruments database
782 iliev 1345 - added support for escape sequences to the instruments database
783 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
784     within the sampler's process (by using instrument editor plugins),
785     you'll notice the new "Registered instrument editors:" message on
786 schoenebeck 1407 startup, added a new LSCP command:
787     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
788 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
789     given sampler channel, the plugin path can be overridden at compile
790     time with ./configure --enable-plugin-dir=/some/dir
791 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
792     in the sampler's process to safely edit instruments while playing
793     without a crash (hopefully) by either suspending single regions
794     wherever possible or if unavoidable whole engine(s)
795 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
796     policy and priority on thread level, set a minimum stack size for
797     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
798     threads simply inherited properties of starting thread instead of
799     setting their own policy and priority
800 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
801     main process did not wait for the stack trace process to finish
802     its output
803 persson 1248 - fixed some minor memory leaks
804 schoenebeck 1259 - reenabled assembly features support, at the moment only for
805     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
806 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
807     register, to avoid relocations in the text segment at runtime)
808 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
809 schoenebeck 947
810     * MIDI driver:
811     - dispatch bank select (MSB and LSB) messages
812    
813 schoenebeck 1049 * audio driver:
814     - the ALSA audio output driver parameters now reflect the correct
815     parameter value ranges for the respective selected sound card
816     (patch by Till Wimmer, a bit fixed and extended)
817    
818 persson 951 * Gigasampler format engine:
819     - if a filter is used and EG2 finishes before EG1, let the voice
820     die when EG2 has finished (this fixes a problem with clicks and
821     voice starvation for some gigs)
822 persson 1038 - playback is no longer disabled during instrument loading
823     - all notes playing on a channel that changes its instrument keep
824     playing with the old instrument until they get a note off
825     command
826 persson 1039 - EG fix: a release value of zero could cause noises or crash
827 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
828 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
829     above max sustain level, which means that there is a decay phase
830     even if sustain is 100%
831 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
832     noises or crashes
833 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
834 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
835     supplied to the configure script (fixes #46)
836 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
837     instead of a fix value
838 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
839     127 (solo mode) only kill voices if the respective mode really
840     changed
841 persson 951
842 schoenebeck 1244 * LSCP server:
843     - fixed compile time error for old Bison versions
844     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
845 schoenebeck 1245 - parser now supports extended ASCII character set
846     (up to ASCII code 255, i.e. includes now umlauts and accents)
847     - filename arguments in LSCP commands now allow to use escape
848     sequences, that is directly literal as one of: \', \", \\, \n, \r,
849     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
850     code value like \xf2) (fixes bug #24)
851 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
852     least one of their text-based parameters (i.e. name, description):
853     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
854     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
855     "SET DB_INSTRUMENT_DIRECTORY NAME",
856     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
857     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
858     "FIND DB_INSTRUMENT_DIRECTORIES"
859 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
860     occured, the unexpected character and the actually expected, possible
861     character(s), the latter only if less than 5 possibilities)
862 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
863     settings
864 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
865     of strings were treated as being one string containing commas
866     (fixes #57)
867 schoenebeck 1244
868 iliev 959 * Bug fixes:
869     - fixed crash occurring on certain LSCP scripts (Bug 39)
870 persson 1038 - another thread safety fix for lscp "load engine" and "set
871     channel audio output device"
872 iliev 1283 - fixed a crash which occurs when reassigning the same engine
873     on a sampler channel with connected MIDI device
874 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
875     device connected to a sampler channel to number less then or equal
876     to the index of the port to which the sampler channel is connected.
877 iliev 1296 - The previous bindings were not been disconnected when altering
878     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
879     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
880 iliev 1297 - The active stream/voice count statistic was incorrect.
881 iliev 1298 - notification events were not been sent for some sampler
882     channel changes
883 iliev 1305 - added default min and max values to restrict the number of allowed
884     audio output channels and MIDI input ports
885 iliev 1306 - the connection to the PCM interface is now closed when destroying
886     an audio output device
887 schoenebeck 1332 - files with slash in their path or filename could not be loaded
888 iliev 959
889 schoenebeck 1221 * test cases:
890     - updated and fixed (haven't been touched in a while)
891    
892 schoenebeck 937 Version 0.4.0 (24 November 2006)
893 persson 696
894 schoenebeck 697 * packaging changes:
895 capela 868 - changed deprecated copyright attribute to license; added ldconfig
896     to post-(un)install steps; added devel package for liblinuxsampler;
897     to linuxsampler.spec (RPM)
898 schoenebeck 697 - install necessary development header files for allowing 3rd party
899     applications to link against liblinuxsampler
900     - liblinuxsampler's API documentation can be generated with 'make docs'
901     (Doxygen required)
902 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
903     implementation (currently either an integer math solution or a
904     di-harmonic approximation), automatic detection can be overriden
905     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
906     configure script argument though (mandatory for cross-compilation)
907 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
908     provided some on his own (as CXXFLAGS)
909 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
910     messages
911 schoenebeck 852 - added compile time options to allow disabling the various audio and
912     MIDI drivers
913 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
914     (patch by Ebrahim Mayat)
915 schoenebeck 697
916 persson 696 * Gigasampler format engine:
917 schoenebeck 738 - extensive synthesis optimization
918     (reimplementation of EGs and LFO(s), removed synthesis parameter
919     prerendering and the synthesis parameter matrix in general, splitting
920     each audio fragment into subfragments now where each subfragment uses
921 persson 830 constant pitch and filter coefficients. The volume coefficient is
922     linearly interpolated inside a subfragment, unless
923     --disable-interpolate-volume is set.)
924 persson 696 - fine tuning of the EG modulation parameters
925 persson 729 - improved filter cutoff calculation by adding support for the
926     following gig parameters: Cutoff freq (used when no cutoff
927     controller is defined), Control invert, Minimum cutoff, Velocity
928 persson 791 curve and Velocity range. The keyboard tracking now scales
929     cutoff frequency instead of resonance.
930 persson 877 - added support for gig parameter Resonance.
931 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
932 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
933     which can be overridden with --enable-global-attenuation
934 persson 783 - EG fixes: made the length of "attack hold" stage more
935     accurate. Release stage can now start before attack stage
936 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
937     time now has a minimal value to prevent clicks.
938 persson 799 - fixed pitch changes larger than one octave
939 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
940     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
941     all modes can be altered via standard GM messages, that is CC5 for
942     altering portamento time, CC65 for enabling / disabling portamento
943     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
944 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
945     parameter) and crossfade
946 persson 831 - added support for the "attenuation controller threshold" gig
947     parameter
948 persson 832 - added smoothing of volume changes caused by control change
949     messages
950 persson 865 - sample loop parameters are now taken from the DimensionRegion
951     instead of the wave chunk
952     - fixed keyswitching for v3 gigs with a number of keyswitch splits
953     not equal to a power of two
954 persson 877 - reimplementation of the filter algorithm. The new filter is more
955     accurate and supports all gig filter types, including bandreject
956     and lowpass turbo.
957 persson 903 - real support for 24 bit samples - samples are not truncated to
958     16 bits anymore
959     - support for aftertouch (channel pressure, not polyphonic
960     aftertouch)
961 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
962     amplifying from 0)
963 persson 696
964 schoenebeck 711 * LSCP server:
965     - fixed application exit on broken pipe error (fixes bug #20)
966 iliev 793 - fixed the notification messages delay due to lack of
967     network activity (fixes bug #26)
968 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
969     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
970 schoenebeck 711
971 schoenebeck 838 * audio driver:
972     - added aRts audio output driver (by no means RT safe)
973    
974 schoenebeck 775 * MIDI driver:
975     - fixed legacy sysex code which caused dispatching of MIDI SysEx
976     messages several times instead of once
977 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
978     for events (i.e. for offline rendering based MIDI drivers)
979 persson 922 - added checks for bad MIDI data
980 schoenebeck 775
981 schoenebeck 900 * linuxsampler application:
982     - show available sampler engine types on startup
983    
984 schoenebeck 705 * general changes:
985     - support for muting sampler channels and solo mode of the same, two new
986     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
987     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
988     introduced for this, the behavior is the same like on a mixer console
989 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
990     --enable-process-muted-channels which can be used to enable the
991     processing of muted channels.
992 iliev 777 - support for sostenuto pedal
993 iliev 779 - support for monitoring the total number of active voices
994 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
995     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
996 persson 835 - fixed some memory management errors
997 persson 841 - fixed some concurrency problems that could lead to crashes when
998     LSCP commands were executed
999 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
1000     sampler channel (fixes bug #36)
1001 schoenebeck 705
1002 schoenebeck 692 Version 0.3.3 (15 July 2005)
1003 schoenebeck 686
1004     * packaging changes:
1005     - fixed compilation with gcc 4.0
1006    
1007 schoenebeck 687 * Gigasampler format engine:
1008     - LFO preprocessing was performed even though the respective LFO was
1009     disabled by the instrument patch (minor efficiency fix)
1010 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1011     for volume ramp downs in the same fragment (needed for current voice
1012     stealing implementation) then simply inform the user with a warning
1013     about possible click sounds and reduce the volume ramp down
1014     appropriately instead of cancelling the audio device connection
1015 schoenebeck 687
1016 schoenebeck 677 Version 0.3.2 (24 June 2005)
1017 schoenebeck 609
1018     * packaging changes:
1019     - updated autotools build files to compile on OS X
1020     (conditional compilation of CoreMIDI and MidiShare drivers)
1021 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
1022     './configure --disable-asm' (definitely not recommended)
1023 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
1024     - require automake (>= 1.5) for 'make -f Makefile.cvs'
1025     (due to 'dist-bzip2' automake option)
1026 schoenebeck 649
1027     * Gigasampler format engine:
1028     - support for the gig parameters for "release velocity response" curves
1029     - fine tuning of the EGADSR envelope
1030     - volume of release triggered samples now depends on note-on velocity,
1031     note length and gig parameter "release trigger decay" instead of
1032     note-off velocity.
1033 schoenebeck 663 - revised voice stealing
1034     (fixes crash and endless loop caused by voice stealing)
1035 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
1036 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
1037     instead of when the respective voice is actually launched
1038     (fixes undefined behavior if stolen voices belonged to a key group -
1039     this case was followed by a "killed voice survived" error message)
1040 schoenebeck 669 - fixed minor issue with null/silence samples
1041     (those stole voices even though they don't need a voice at all which
1042     resulted in "voice stealing didn't work out" messages)
1043 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
1044     instrument or audio output device change
1045 schoenebeck 654
1046 schoenebeck 620 * LSCP server:
1047 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1048 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
1049 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
1050 schoenebeck 609
1051 schoenebeck 668 * linuxsampler application:
1052     - added command line parameters --lscp-addr and --lscp-port to override
1053     default IP address and port of LSCP server
1054    
1055 schoenebeck 579 Version 0.3.1 (24 May 2005)
1056    
1057     * initial release
