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

125     filter parameters in each sub fragment)
126     - handle special case when pan parameter in gig file has max or
127     min value
128 schoenebeck 2396 - Exclusive Groups: don't ever stop voices of the same note,
129     doesn't sound naturally with a drumkit
130 persson 2408 - fixed EG1 modulation when attack or release is zero
131 schoenebeck 2559 - Fixed support for 'aftertouch' attenuation controller.

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

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

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

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

621 persson 1748 jack_client_new
622 iliev 1829 - added (experimental) CoreAudio driver
623 persson 1888 - applied old fixes to the ASIO driver that were included in the
624     previous binary release but accidentally never committed to CVS
625     (fixes #117)
626 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on

663     instrument database compilable
664 schoenebeck 1930 - added instrument database support on Windows
665     works with both standalone mode and VST plugin.
666     the instruments DB file is located in
667     %USERPROFILE%\.linuxsampler\instruments.db which allows different
668     databases for each windows user
669     if no DB is present it automatically creates the .linuxsampler subdir
670     and then creates an empty DB
671 persson 1943 - fixed recursive import, which was broken on Windows
672 iliev 1603
673 persson 1644 * Gigasampler format engine:
674     - fixed a memory leak that could happen when a channel was deleted

676 persson 1646 - made it possible to load an instrument even if the audio thread
677     isn't running
678 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
679     enough for piano gigs with pedal noise samples
680 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
681     respective FX send MIDI controller was used
682 schoenebeck 1724 - added support for GM global device volume SysEx message
683 schoenebeck 1762 (can be selected at compile time to either apply globally to the
684     whole sampler [default] or only to the sampler channels that are
685     connected to the respective MIDI input port the SysEx message arrived
686     on)
687 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
688     sometimes wrongly killed in the same buffer, causing no sound to
689     be played
690 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
691     which is usally used to switch a part between chromatic sounds and
692     drumkit sounds (as opposed to their common default setting of MIDI
693     part 10 being a drumkit part and all other ones chromatic parts), in
694     LS however one can switch between the first 16 MIDI instrument maps
695     defined for the sampler
696 persson 1764 - made it possible to create multiple sample channels even if the
697     audio thread isn't running

701     sampler engine anymore
702     - re-cache samples in case they were changed by an instrument editor,
703     e.g. when a sample was added while playing (#82)
704 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
705     same time stamp as the voice's note-on event and occured both in the
706     same audio fragment cycle (fixes bug #112)
707 persson 1858 - added support for the "fine tune" and "pitch bend range"
708     instrument-level gig parameters
709     - fixed minor artifacts in pitch bend handling
710 schoenebeck 1860 - added support for GS Reset SysEx message
711 persson 1862 - allow gig files to use unlimited downward pitch shifting
712     - added a limit check for upward pitch shifting
713 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
714     note was silent
715 persson 1923 - fixed crash happening when a pitch bend event arrived at the
716     same time a new instrument was loading
717 persson 1644
718 schoenebeck 1687 * LSCP server:
719     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
720     react on MIDI data arriving on certain sampler channels (so far only
721     Note-On and Note-Off events are sent via this LSCP event)
722 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
723     react on MIDI data arriving on certain MIDI input devices (so far only
724     Note-On and Note-Off events are sent via this LSCP event)
725 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
726     SET DB_INSTRUMENT FILE_PATH
727 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
728     frontends to send MIDI messages to specific sampler channel
729     - added two additional fields to GET FILE INSTRUMENT INFO command -
730     KEY_BINDINGS and KEYSWITCH_BINDINGS
731 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
732     was incorrect
733 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
734 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
735     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
736     be triggered respectively
737     - added new LSCP command "SET STREAMS" to globally alter the maximum
738     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
739     which will be triggered respectively
740 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
741     a gigedit file dialog is opened)
742 iliev 1848 - close all connections when LSCPServer is deleted
743 iliev 1882 - hard close of all sockets on exit
744 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
745     driver
746 schoenebeck 1687
747 iliev 1761 * Bug fixes:
748     - fixed a crash which occurs when removing a sampler channel waiting
749     to start instrument loading after another channel
750 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
751     instrument loading in progress (bug #113)
752 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
753     instrument with PERSISTENT load mode
754 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
755     - fixed memory leaks when issuing the following LSCP commands:

757     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
758     GET MIDI_INPUT_DRIVER INFO
759     GET MIDI_INPUT_DRIVER_PARAMETER INFO
760     - fixed possible compilation error when sqlite is not present
761 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
762 iliev 1847 - fixed crash when changing the audio output device of a sampler
763     channel with loaded instrument and start playing notes
764 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
765 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
766     PowerPC, which probably could cause crashes on that platform
767 persson 1889 - fixed a memory management error which could cause a crash when a
768     plugin was unloaded
769 persson 1896 - bugfix: two private structs had the same name, which could cause
770     problems if the linker chose the wrong constructor
771 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
772     Windows

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