49 persson 2382
50 persson 2086 * general changes:
51 iliev 2012 - Refactoring: moved the independent code from
52     the Gigasampler format engine to base classes
53 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
54     respective profiling code is currently broken
55 schoenebeck 2053 - Introduced support for optional environment variable
56     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
57     where the sampler shall look for instrument editor plugins
58     (patch by Luis Garrido, slightly modified).
59 schoenebeck 2121 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
60     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
61     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
62     note (in this implementation of the sampler its simply hard routed to
63     the 1st effect send of the sampler channel, no matter what the actual
64     effect type is)
65     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
66     note (in this implementation of the sampler its simply hard routed to
67     the 2nd effect send of the sampler channel, no matter what the actual
68     effect type is)
69 schoenebeck 2124 - implemented support for internal LADSPA effects
70 schoenebeck 2140 - raised limit of program change queue from 100 to 512
71     (as suggested by Alex Stone)
72 iliev 2223 - implemented sine LFO, pulse LFO and saw LFO
73 iliev 2296 - experimental support for per voice equalization
74 iliev 2306 - added command line option --exec-after-init
75 schoenebeck 2330 - Introduced new C++ API method:
76     EngineChannel::InstrumentFileName(int index)
77     allowing to retrieve the whole list of files used for the loaded
78     instrument on an engine channel (a.k.a. part). Some GigaStudio
79     instruments for example are splitted over several files like
80     "Foo.gig", "Foo.gx01", "Foo.gx02", ...
81 schoenebeck 2375 - Added new C++ API method Sampler::GetGlobalMaxVoices().
82     - Added new C++ API method Sampler::GetGlobalMaxStreams().
83     - Added new C++ API method Sampler::SetGlobalMaxVoices().
84     - Added new C++ API method Sampler::SetGlobalMaxStreams().
85 schoenebeck 2377 - Various "const" and "restrict" optimizations.
86 persson 2382 - all engines: add pan CC value to instrument pan parameter before
87     applying panning, instead of using two separate pan functions in
88     series (#182)
89 persson 2427 - added a lock guard class for exception safe mutex handling and
90     used it everywhere appropriate
91 schoenebeck 2448 - Immediately apply scale tuning changes to active voices.
92     - Exposed scale tuning to C++ API (along to the already existing standard
93     SysEx way).
94 persson 2452 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
95     and broken for ppc64. (Seq_cst loads and stores are actually not
96     used in LS, so the bug wasn't noticable.)
97     - lsatomic.h: added ARMv7 support
98 schoenebeck 2500 - Added support for multiple MIDI input ports per sampler channel (and
99     added various new C++ methods for this new feature / design change, old
100     C++ API methods for managing SamplerChannel's MIDI inputs are now marked
101     as deprecated but are still there and should provide full behavior
102     backward compatibility).
103     - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
104     unsafe and caused compilation error with clang 2.x).
105 schoenebeck 2506 - Bugfix: only process the latest MIDI program change event.
106 schoenebeck 2515 - Introducing the LSCP shell, which provides convenient control of the
107     sampler from the command line by providing LSCP aware features.
108 schoenebeck 2521 - VirtualMidiDevice: Added support for program change.
109     - VirtualMidiDevice: Added support for bank select (MSB & LSB).
110     - VirtualMidiDevice: Added support for pitch bend.
111 schoenebeck 2559 - Aftertouch: extended API to explicitly handle channel pressure and
112     polyphonic key pressure events (so far polyphonic pressure was not
113     supported at all, and channel pressure was rerouted as CC128 but not
114     used so far).
115 schoenebeck 2594 - Added initial support for real-time instrument scripts. The script VM
116     code is shared by all sampler engine implemementations, however only the
117     gig file format currently provides support for storing instrument scripts
118     (as LinuxSampler extension to the original GigaStudio 4 format).
119 iliev 2012
120 persson 2043 * Gigasampler format engine:
121     - implemented the "round robin keyboard" dimension
122     - fixed round robin and random dimensions for cases when number of

129     filter parameters in each sub fragment)
130     - handle special case when pan parameter in gig file has max or
131     min value
132 schoenebeck 2396 - Exclusive Groups: don't ever stop voices of the same note,
133     doesn't sound naturally with a drumkit

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

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

541 schoenebeck 2509 - ignore missing LADSPA paths without ignoring valid LADSPA paths
542     (fixes #208)
543 schoenebeck 2523 - Fixed bug in LSCP grammar definition which caused a statement like
544     "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
545     practically irrelevant, however it caused problems with the new LSCP
546     shell's auto completion feature).
547 schoenebeck 2672 - Fixed MIDI program change messages being ignored if quickly executed
548     after each other (fixes #231).

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

627 persson 1888 - applied old fixes to the ASIO driver that were included in the
628     previous binary release but accidentally never committed to CVS
629     (fixes #117)
630 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on

667     instrument database compilable
668 schoenebeck 1930 - added instrument database support on Windows
669     works with both standalone mode and VST plugin.
670     the instruments DB file is located in
671     %USERPROFILE%\.linuxsampler\instruments.db which allows different
672     databases for each windows user
673     if no DB is present it automatically creates the .linuxsampler subdir
674     and then creates an empty DB
675 persson 1943 - fixed recursive import, which was broken on Windows
676 iliev 1603
677 persson 1644 * Gigasampler format engine:
678     - fixed a memory leak that could happen when a channel was deleted
679     while notes were playing
680 persson 1646 - made it possible to load an instrument even if the audio thread
681     isn't running
682 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
683     enough for piano gigs with pedal noise samples
684 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
685     respective FX send MIDI controller was used
686 schoenebeck 1724 - added support for GM global device volume SysEx message
687 schoenebeck 1762 (can be selected at compile time to either apply globally to the
688     whole sampler [default] or only to the sampler channels that are
689     connected to the respective MIDI input port the SysEx message arrived
690     on)
691 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
692     sometimes wrongly killed in the same buffer, causing no sound to
693     be played
694 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
695     which is usally used to switch a part between chromatic sounds and
696     drumkit sounds (as opposed to their common default setting of MIDI
697     part 10 being a drumkit part and all other ones chromatic parts), in
698     LS however one can switch between the first 16 MIDI instrument maps
699     defined for the sampler
700 persson 1764 - made it possible to create multiple sample channels even if the
701     audio thread isn't running
702 persson 1844 - fixed crash when removing channel with active voices (#116)
703 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
704     un-cache the respective sample if it's really not used by any
705     sampler engine anymore
706     - re-cache samples in case they were changed by an instrument editor,
707     e.g. when a sample was added while playing (#82)
708 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
709     same time stamp as the voice's note-on event and occured both in the
710     same audio fragment cycle (fixes bug #112)
711 persson 1858 - added support for the "fine tune" and "pitch bend range"
712     instrument-level gig parameters
713     - fixed minor artifacts in pitch bend handling
714 schoenebeck 1860 - added support for GS Reset SysEx message
715 persson 1862 - allow gig files to use unlimited downward pitch shifting

717 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
718     note was silent
719 persson 1923 - fixed crash happening when a pitch bend event arrived at the
720     same time a new instrument was loading
721 persson 1644
722 schoenebeck 1687 * LSCP server:
723     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
724     react on MIDI data arriving on certain sampler channels (so far only
725     Note-On and Note-Off events are sent via this LSCP event)
726 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
727     react on MIDI data arriving on certain MIDI input devices (so far only
728     Note-On and Note-Off events are sent via this LSCP event)
729 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
730     SET DB_INSTRUMENT FILE_PATH
731 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
732     frontends to send MIDI messages to specific sampler channel
733     - added two additional fields to GET FILE INSTRUMENT INFO command -
734     KEY_BINDINGS and KEYSWITCH_BINDINGS
735 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
736     was incorrect
737 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
738 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
739     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
740     be triggered respectively
741     - added new LSCP command "SET STREAMS" to globally alter the maximum
742     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
743     which will be triggered respectively
744 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
745     a gigedit file dialog is opened)
746 iliev 1848 - close all connections when LSCPServer is deleted
747 iliev 1882 - hard close of all sockets on exit
748 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
749     driver
750 schoenebeck 1687
751 iliev 1761 * Bug fixes:
752     - fixed a crash which occurs when removing a sampler channel waiting
753     to start instrument loading after another channel
754 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
755     instrument loading in progress (bug #113)
756 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
757     instrument with PERSISTENT load mode
758 iliev 1835 - fixed possible iterator invalidations when resetting the sampler

762     GET MIDI_INPUT_DRIVER INFO
763     GET MIDI_INPUT_DRIVER_PARAMETER INFO
764     - fixed possible compilation error when sqlite is not present
765 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
766 iliev 1847 - fixed crash when changing the audio output device of a sampler
767     channel with loaded instrument and start playing notes
768 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
769 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
770     PowerPC, which probably could cause crashes on that platform
771 persson 1889 - fixed a memory management error which could cause a crash when a
772     plugin was unloaded
773 persson 1896 - bugfix: two private structs had the same name, which could cause
774     problems if the linker chose the wrong constructor
775 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
776     Windows
777 iliev 1761
778    
779 schoenebeck 1560 Version 0.5.1 (6 December 2007)
780 schoenebeck 1454
781     * packaging changes:
782     - added autoconf checks for pthread library
783     - added autoconf check for pthread bug found on certain NPTL-enabled
784     glibc versions (see Gentoo bug report #194076)
785 senoner 1502 - added autoconf checks for MS Windows
786 schoenebeck 1454
787 persson 1455 * general changes:
788     - bugfix: the thread used by an editor plugin didn't die when the
789     editor closed
790 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
791     out all the space. operator--() did not apply size_mask after
792     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
793     order to avoid problems with the _NonVolatileReader functions.
794     - bugfix: Stream.h: added a missing divide by BytesPerSample in
795     GetWriteSpace(). Since this function is currently only used in
796     the stream's qsort() compare function, it didn't trigger any
797     bugs.
798     - Resampler.h, Synthesizer.h: cubic interpolation now works in
799     24bit mode too. Faster method to read 24bit words on little
800     endian machines (x86): replaced 3 byte reads + shifts with a 1
801     unaligned 32bit read and shift
802     - experimental support for MS Windows (MIDI input via MME, AUDIO
803     output via ASIO)
804     - made handling of SIGINT signal (Ctrl-C) a bit more robust
805 iliev 1541 - support for monitoring the total number of active disk streams
806     (new LSCP commands: GET TOTAL_STREAM_COUNT,
807     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
808 persson 1455
809 senoner 1500 * AUDIO driver:
810 persson 1534 - added Windows ASIO low latency audio driver
811 senoner 1500
812 senoner 1485 * MIDI driver:
813 schoenebeck 1495 - added MME Windows MIDI driver
814 senoner 1485
815 schoenebeck 1471 * LSCP server:
816     - added support for Windows style path / filenames, however with
817     forward slash path separators instead of backslash
818     (i.e. "C:/foo/bar.gig")
819 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
820     apostrophes as well
821 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
822     "LIST FILE INSTRUMENTS <file>" and
823     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
824     about an arbitrary instrument file on the system where the sampler is
825     running on
826 schoenebeck 1471
827 schoenebeck 1424 Version 0.5.0 (15 October 2007)
828 schoenebeck 947
829 schoenebeck 1065 * packaging changes:
830 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
831     API header files anymore
832 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
833     the Doxygen API documentation (explicitly listed in Doxyfile.in)
834 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
835     capable to execute our autoconf environment, thus no need anymore
836     to maintain the compile time configuration file (osx/version.h) for
837     OSX manually (patch by Toshi Nagata)
838 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
839     parameters
840 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
841     C++ API header files, all implementation internal global definitions
842     are now in global_private.h
843     - atomic.h is not exposed to the C++ API anymore
844     - no need to include config.h anymore for using LS's API header files
845     - fixed warnings in API doc generation
846 schoenebeck 1065
847 schoenebeck 947 * general changes:
848     - replaced the old, confusing MIDI program change mechanism by a
849     flexible MIDI instrument mapper which allows to map arbitrary
850 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
851 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
852     loaded on the respective channel when such MIDI program change
853     messages arrive, beside that, each entry allows to define a life-time
854     strategy for the instrument, so the user can define whether the
855     instrument should i.e. be permanently loaded (to be able to switch
856     quickly among sounds) or i.e. loaded just on demand when the
857     respective program change arrives (to safe RAM space), as well as a
858     global volume factor for each entry, so the user can adjust the volume
859     dynamic of his mapped instrument collection without having to modify
860 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
861     MIDI instrument maps and assign each sampler channel individually
862     a certain map, so that i.e. separation of normal instruments and
863     drumkits is possible
864 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
865     MIDI instrument maps, MIDI instruments, FX sends, global volume.
866 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
867     due to a constant size RingBuffer FIFO which is now replaced by a
868     dynamic (unlimited) size std::list FIFO
869 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
870     output channels for being processed by external effect processors
871     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
872     controllers
873 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
874 iliev 1130 - Implemented new, improved notification system
875 schoenebeck 1149 - fixed compilation errors regarding OSX
876     (patch by Toshi Nagata)
877 iliev 1161 - implemented instruments database
878 iliev 1345 - added support for escape sequences to the instruments database
879 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
880     within the sampler's process (by using instrument editor plugins),
881     you'll notice the new "Registered instrument editors:" message on
882 schoenebeck 1407 startup, added a new LSCP command:
883     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
884 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
885     given sampler channel, the plugin path can be overridden at compile
886     time with ./configure --enable-plugin-dir=/some/dir
887 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
888     in the sampler's process to safely edit instruments while playing
889     without a crash (hopefully) by either suspending single regions
890     wherever possible or if unavoidable whole engine(s)
891 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
892     policy and priority on thread level, set a minimum stack size for
893     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
894     threads simply inherited properties of starting thread instead of
895     setting their own policy and priority
896 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
897     main process did not wait for the stack trace process to finish
898     its output
899 persson 1248 - fixed some minor memory leaks
900 schoenebeck 1259 - reenabled assembly features support, at the moment only for
901     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
902 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
903     register, to avoid relocations in the text segment at runtime)
904 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
905 schoenebeck 947
906     * MIDI driver:
907     - dispatch bank select (MSB and LSB) messages
908    
909 schoenebeck 1049 * audio driver:
910     - the ALSA audio output driver parameters now reflect the correct
911     parameter value ranges for the respective selected sound card
912     (patch by Till Wimmer, a bit fixed and extended)
913    
914 persson 951 * Gigasampler format engine:
915     - if a filter is used and EG2 finishes before EG1, let the voice
916     die when EG2 has finished (this fixes a problem with clicks and
917     voice starvation for some gigs)
918 persson 1038 - playback is no longer disabled during instrument loading
919     - all notes playing on a channel that changes its instrument keep
920     playing with the old instrument until they get a note off
921     command
922 persson 1039 - EG fix: a release value of zero could cause noises or crash
923 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
924 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
925     above max sustain level, which means that there is a decay phase
926     even if sustain is 100%
927 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
928     noises or crashes
929 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
930 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
931     supplied to the configure script (fixes #46)
932 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
933     instead of a fix value
934 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
935     127 (solo mode) only kill voices if the respective mode really
936     changed
937 persson 951
938 schoenebeck 1244 * LSCP server:
939     - fixed compile time error for old Bison versions
940     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
941 schoenebeck 1245 - parser now supports extended ASCII character set
942     (up to ASCII code 255, i.e. includes now umlauts and accents)
943     - filename arguments in LSCP commands now allow to use escape
944     sequences, that is directly literal as one of: \', \", \\, \n, \r,
945     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
946     code value like \xf2) (fixes bug #24)
947 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
948     least one of their text-based parameters (i.e. name, description):
949     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
950     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
951     "SET DB_INSTRUMENT_DIRECTORY NAME",
952     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
953     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
954     "FIND DB_INSTRUMENT_DIRECTORIES"
955 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
956     occured, the unexpected character and the actually expected, possible
957     character(s), the latter only if less than 5 possibilities)
958 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
959     settings
960 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
961     of strings were treated as being one string containing commas
962     (fixes #57)
963 schoenebeck 1244
964 iliev 959 * Bug fixes:
965     - fixed crash occurring on certain LSCP scripts (Bug 39)
966 persson 1038 - another thread safety fix for lscp "load engine" and "set
967     channel audio output device"
968 iliev 1283 - fixed a crash which occurs when reassigning the same engine
969     on a sampler channel with connected MIDI device
970 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
971     device connected to a sampler channel to number less then or equal
972     to the index of the port to which the sampler channel is connected.
973 iliev 1296 - The previous bindings were not been disconnected when altering
974     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
975     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
976 iliev 1297 - The active stream/voice count statistic was incorrect.
977 iliev 1298 - notification events were not been sent for some sampler
978     channel changes
979 iliev 1305 - added default min and max values to restrict the number of allowed
980     audio output channels and MIDI input ports
981 iliev 1306 - the connection to the PCM interface is now closed when destroying
982     an audio output device
983 schoenebeck 1332 - files with slash in their path or filename could not be loaded
984 iliev 959
985 schoenebeck 1221 * test cases:
986     - updated and fixed (haven't been touched in a while)
987    
988 schoenebeck 937 Version 0.4.0 (24 November 2006)
989 persson 696
990 schoenebeck 697 * packaging changes:
991 capela 868 - changed deprecated copyright attribute to license; added ldconfig
992     to post-(un)install steps; added devel package for liblinuxsampler;
993     to linuxsampler.spec (RPM)
994 schoenebeck 697 - install necessary development header files for allowing 3rd party
995     applications to link against liblinuxsampler
996     - liblinuxsampler's API documentation can be generated with 'make docs'
997     (Doxygen required)
998 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
999     implementation (currently either an integer math solution or a
1000     di-harmonic approximation), automatic detection can be overriden
1001     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1002     configure script argument though (mandatory for cross-compilation)
1003 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
1004     provided some on his own (as CXXFLAGS)
1005 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
1006     messages
1007 schoenebeck 852 - added compile time options to allow disabling the various audio and
1008     MIDI drivers
1009 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
1010     (patch by Ebrahim Mayat)
1011 schoenebeck 697
1012 persson 696 * Gigasampler format engine:
1013 schoenebeck 738 - extensive synthesis optimization
1014     (reimplementation of EGs and LFO(s), removed synthesis parameter
1015     prerendering and the synthesis parameter matrix in general, splitting
1016     each audio fragment into subfragments now where each subfragment uses
1017 persson 830 constant pitch and filter coefficients. The volume coefficient is
1018     linearly interpolated inside a subfragment, unless
1019     --disable-interpolate-volume is set.)
1020 persson 696 - fine tuning of the EG modulation parameters
1021 persson 729 - improved filter cutoff calculation by adding support for the
1022     following gig parameters: Cutoff freq (used when no cutoff
1023     controller is defined), Control invert, Minimum cutoff, Velocity
1024 persson 791 curve and Velocity range. The keyboard tracking now scales
1025     cutoff frequency instead of resonance.
1026 persson 877 - added support for gig parameter Resonance.
1027 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
1028 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1029     which can be overridden with --enable-global-attenuation
1030 persson 783 - EG fixes: made the length of "attack hold" stage more
1031     accurate. Release stage can now start before attack stage
1032 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
1033     time now has a minimal value to prevent clicks.
1034 persson 799 - fixed pitch changes larger than one octave
1035 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1036     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1037     all modes can be altered via standard GM messages, that is CC5 for
1038     altering portamento time, CC65 for enabling / disabling portamento
1039     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1040 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1041     parameter) and crossfade
1042 persson 831 - added support for the "attenuation controller threshold" gig
1043     parameter
1044 persson 832 - added smoothing of volume changes caused by control change
1045     messages
1046 persson 865 - sample loop parameters are now taken from the DimensionRegion
1047     instead of the wave chunk
1048     - fixed keyswitching for v3 gigs with a number of keyswitch splits
1049     not equal to a power of two
1050 persson 877 - reimplementation of the filter algorithm. The new filter is more
1051     accurate and supports all gig filter types, including bandreject
1052     and lowpass turbo.
1053 persson 903 - real support for 24 bit samples - samples are not truncated to
1054     16 bits anymore
1055     - support for aftertouch (channel pressure, not polyphonic
1056     aftertouch)
1057 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
1058     amplifying from 0)
1059 persson 696
1060 schoenebeck 711 * LSCP server:
1061     - fixed application exit on broken pipe error (fixes bug #20)
1062 iliev 793 - fixed the notification messages delay due to lack of
1063     network activity (fixes bug #26)
1064 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
1065     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1066 schoenebeck 711
1067 schoenebeck 838 * audio driver:
1068     - added aRts audio output driver (by no means RT safe)
1069    
1070 schoenebeck 775 * MIDI driver:
1071     - fixed legacy sysex code which caused dispatching of MIDI SysEx
1072     messages several times instead of once
1073 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
1074     for events (i.e. for offline rendering based MIDI drivers)
1075 persson 922 - added checks for bad MIDI data
1076 schoenebeck 775
1077 schoenebeck 900 * linuxsampler application:
1078     - show available sampler engine types on startup
1079    
1080 schoenebeck 705 * general changes:
1081     - support for muting sampler channels and solo mode of the same, two new
1082     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1083     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1084     introduced for this, the behavior is the same like on a mixer console
1085 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1086     --enable-process-muted-channels which can be used to enable the
1087     processing of muted channels.
1088 iliev 777 - support for sostenuto pedal
1089 iliev 779 - support for monitoring the total number of active voices
1090 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1091     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1092 persson 835 - fixed some memory management errors
1093 persson 841 - fixed some concurrency problems that could lead to crashes when
1094     LSCP commands were executed
1095 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
1096     sampler channel (fixes bug #36)
1097 schoenebeck 705
1098 schoenebeck 692 Version 0.3.3 (15 July 2005)
1099 schoenebeck 686
1100     * packaging changes:
1101     - fixed compilation with gcc 4.0
1102    
1103 schoenebeck 687 * Gigasampler format engine:
1104     - LFO preprocessing was performed even though the respective LFO was
1105     disabled by the instrument patch (minor efficiency fix)
1106 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1107     for volume ramp downs in the same fragment (needed for current voice
1108     stealing implementation) then simply inform the user with a warning
1109     about possible click sounds and reduce the volume ramp down
1110     appropriately instead of cancelling the audio device connection
1111 schoenebeck 687
1112 schoenebeck 677 Version 0.3.2 (24 June 2005)
1113 schoenebeck 609
1114     * packaging changes:
1115     - updated autotools build files to compile on OS X
1116     (conditional compilation of CoreMIDI and MidiShare drivers)
1117 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
1118     './configure --disable-asm' (definitely not recommended)
1119 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
1120     - require automake (>= 1.5) for 'make -f Makefile.cvs'
1121     (due to 'dist-bzip2' automake option)
1122 schoenebeck 649
1123     * Gigasampler format engine:
1124     - support for the gig parameters for "release velocity response" curves
1125     - fine tuning of the EGADSR envelope
1126     - volume of release triggered samples now depends on note-on velocity,
1127     note length and gig parameter "release trigger decay" instead of
1128     note-off velocity.
1129 schoenebeck 663 - revised voice stealing
1130     (fixes crash and endless loop caused by voice stealing)
1131 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
1132 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
1133     instead of when the respective voice is actually launched
1134     (fixes undefined behavior if stolen voices belonged to a key group -
1135     this case was followed by a "killed voice survived" error message)
1136 schoenebeck 669 - fixed minor issue with null/silence samples
1137     (those stole voices even though they don't need a voice at all which
1138     resulted in "voice stealing didn't work out" messages)
1139 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
1140     instrument or audio output device change
1141 schoenebeck 654
1142 schoenebeck 620 * LSCP server:
1143 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1144 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
1145 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
1146 schoenebeck 609
1147 schoenebeck 668 * linuxsampler application:
1148     - added command line parameters --lscp-addr and --lscp-port to override
1149     default IP address and port of LSCP server
1150    
1151 schoenebeck 579 Version 0.3.1 (24 May 2005)
1152    
1153     * initial release
