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

126     - fixed round robin and random dimensions for cases when number of
127     dimension zones is not a power of two

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

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

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

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

606     a pointer to the launched InstrumentEditor object
607 schoenebeck 1876 - added optional 3rd party user data parameter for following

671     instrument database compilable
672 schoenebeck 1930 - added instrument database support on Windows
673     works with both standalone mode and VST plugin.
674     the instruments DB file is located in
675     %USERPROFILE%\.linuxsampler\instruments.db which allows different

687     enough for piano gigs with pedal noise samples
688 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
689     respective FX send MIDI controller was used
690 schoenebeck 1724 - added support for GM global device volume SysEx message
691 schoenebeck 1762 (can be selected at compile time to either apply globally to the

699     which is usally used to switch a part between chromatic sounds and
700     drumkit sounds (as opposed to their common default setting of MIDI
701     part 10 being a drumkit part and all other ones chromatic parts), in
702     LS however one can switch between the first 16 MIDI instrument maps
703     defined for the sampler
704 persson 1764 - made it possible to create multiple sample channels even if the
705     audio thread isn't running
706 persson 1844 - fixed crash when removing channel with active voices (#116)
707 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
708     un-cache the respective sample if it's really not used by any
709     sampler engine anymore
710     - re-cache samples in case they were changed by an instrument editor,
711     e.g. when a sample was added while playing (#82)
712 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
713     same time stamp as the voice's note-on event and occured both in the
714     same audio fragment cycle (fixes bug #112)
715 persson 1858 - added support for the "fine tune" and "pitch bend range"
716     instrument-level gig parameters
717     - fixed minor artifacts in pitch bend handling
718 schoenebeck 1860 - added support for GS Reset SysEx message
719 persson 1862 - allow gig files to use unlimited downward pitch shifting
720     - added a limit check for upward pitch shifting
721 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
722     note was silent
723 persson 1923 - fixed crash happening when a pitch bend event arrived at the
724     same time a new instrument was loading
725 persson 1644
726 schoenebeck 1687 * LSCP server:
727     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
728     react on MIDI data arriving on certain sampler channels (so far only
729     Note-On and Note-Off events are sent via this LSCP event)
730 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
731     react on MIDI data arriving on certain MIDI input devices (so far only
732     Note-On and Note-Off events are sent via this LSCP event)
733 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
734     SET DB_INSTRUMENT FILE_PATH
735 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
736     frontends to send MIDI messages to specific sampler channel
737     - added two additional fields to GET FILE INSTRUMENT INFO command -
738     KEY_BINDINGS and KEYSWITCH_BINDINGS
739 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
740     was incorrect
741 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
742 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
743     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
744     be triggered respectively
745     - added new LSCP command "SET STREAMS" to globally alter the maximum
746     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
747     which will be triggered respectively
748 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
749     a gigedit file dialog is opened)
750 iliev 1848 - close all connections when LSCPServer is deleted
751 iliev 1882 - hard close of all sockets on exit
752 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
753     driver
754 schoenebeck 1687
755 iliev 1761 * Bug fixes:
756     - fixed a crash which occurs when removing a sampler channel waiting
757     to start instrument loading after another channel
758 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
759     instrument loading in progress (bug #113)
760 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
761     instrument with PERSISTENT load mode
762 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
763     - fixed memory leaks when issuing the following LSCP commands:
764     GET AUDIO_OUTPUT_DRIVER INFO
765     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
766     GET MIDI_INPUT_DRIVER INFO
767     GET MIDI_INPUT_DRIVER_PARAMETER INFO
768     - fixed possible compilation error when sqlite is not present
769 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
770 iliev 1847 - fixed crash when changing the audio output device of a sampler
771     channel with loaded instrument and start playing notes
772 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
773 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
774     PowerPC, which probably could cause crashes on that platform
775 persson 1889 - fixed a memory management error which could cause a crash when a
776     plugin was unloaded
777 persson 1896 - bugfix: two private structs had the same name, which could cause
778     problems if the linker chose the wrong constructor
779 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
780     Windows
781 iliev 1761
782    
783 schoenebeck 1560 Version 0.5.1 (6 December 2007)
784 schoenebeck 1454
785     * packaging changes:
786     - added autoconf checks for pthread library
787     - added autoconf check for pthread bug found on certain NPTL-enabled
788     glibc versions (see Gentoo bug report #194076)
789 senoner 1502 - added autoconf checks for MS Windows
790 schoenebeck 1454
791 persson 1455 * general changes:
792     - bugfix: the thread used by an editor plugin didn't die when the
793     editor closed
794 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
795     out all the space. operator--() did not apply size_mask after
796     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
797     order to avoid problems with the _NonVolatileReader functions.
798     - bugfix: Stream.h: added a missing divide by BytesPerSample in
799     GetWriteSpace(). Since this function is currently only used in
800     the stream's qsort() compare function, it didn't trigger any
801     bugs.
802     - Resampler.h, Synthesizer.h: cubic interpolation now works in
803     24bit mode too. Faster method to read 24bit words on little
804     endian machines (x86): replaced 3 byte reads + shifts with a 1
805     unaligned 32bit read and shift
806     - experimental support for MS Windows (MIDI input via MME, AUDIO
807     output via ASIO)
808     - made handling of SIGINT signal (Ctrl-C) a bit more robust
809 iliev 1541 - support for monitoring the total number of active disk streams
810     (new LSCP commands: GET TOTAL_STREAM_COUNT,
811     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
812 persson 1455
813 senoner 1500 * AUDIO driver:
814 persson 1534 - added Windows ASIO low latency audio driver
815 senoner 1500
816 senoner 1485 * MIDI driver:
817 schoenebeck 1495 - added MME Windows MIDI driver
818 senoner 1485
819 schoenebeck 1471 * LSCP server:
820     - added support for Windows style path / filenames, however with
821     forward slash path separators instead of backslash
822     (i.e. "C:/foo/bar.gig")
823 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
824     apostrophes as well
825 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
826     "LIST FILE INSTRUMENTS <file>" and
827     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
828     about an arbitrary instrument file on the system where the sampler is
829     running on
830 schoenebeck 1471
831 schoenebeck 1424 Version 0.5.0 (15 October 2007)
832 schoenebeck 947
833 schoenebeck 1065 * packaging changes:
834 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
835     API header files anymore
836 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
837     the Doxygen API documentation (explicitly listed in Doxyfile.in)
838 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
839     capable to execute our autoconf environment, thus no need anymore
840     to maintain the compile time configuration file (osx/version.h) for
841     OSX manually (patch by Toshi Nagata)
842 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
843     parameters
844 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
845     C++ API header files, all implementation internal global definitions
846     are now in global_private.h
847     - atomic.h is not exposed to the C++ API anymore
848     - no need to include config.h anymore for using LS's API header files
849     - fixed warnings in API doc generation
850 schoenebeck 1065
851 schoenebeck 947 * general changes:
852     - replaced the old, confusing MIDI program change mechanism by a
853     flexible MIDI instrument mapper which allows to map arbitrary
854 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
855 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
856     loaded on the respective channel when such MIDI program change
857     messages arrive, beside that, each entry allows to define a life-time
858     strategy for the instrument, so the user can define whether the
859     instrument should i.e. be permanently loaded (to be able to switch
860     quickly among sounds) or i.e. loaded just on demand when the
861     respective program change arrives (to safe RAM space), as well as a
862     global volume factor for each entry, so the user can adjust the volume
863     dynamic of his mapped instrument collection without having to modify
864 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
865     MIDI instrument maps and assign each sampler channel individually
866     a certain map, so that i.e. separation of normal instruments and
867     drumkits is possible
868 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
869     MIDI instrument maps, MIDI instruments, FX sends, global volume.
870 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
871     due to a constant size RingBuffer FIFO which is now replaced by a
872     dynamic (unlimited) size std::list FIFO
873 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
874     output channels for being processed by external effect processors
875     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
876     controllers
877 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
878 iliev 1130 - Implemented new, improved notification system
879 schoenebeck 1149 - fixed compilation errors regarding OSX
880     (patch by Toshi Nagata)
881 iliev 1161 - implemented instruments database
882 iliev 1345 - added support for escape sequences to the instruments database
883 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
884     within the sampler's process (by using instrument editor plugins),
885     you'll notice the new "Registered instrument editors:" message on
886 schoenebeck 1407 startup, added a new LSCP command:
887     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
888 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
889     given sampler channel, the plugin path can be overridden at compile
890     time with ./configure --enable-plugin-dir=/some/dir
891 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
892     in the sampler's process to safely edit instruments while playing
893     without a crash (hopefully) by either suspending single regions
894     wherever possible or if unavoidable whole engine(s)
895 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
896     policy and priority on thread level, set a minimum stack size for
897     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
898     threads simply inherited properties of starting thread instead of
899     setting their own policy and priority
900 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
901     main process did not wait for the stack trace process to finish
902     its output
903 persson 1248 - fixed some minor memory leaks
904 schoenebeck 1259 - reenabled assembly features support, at the moment only for
905     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
906 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
907     register, to avoid relocations in the text segment at runtime)
908 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
909 schoenebeck 947
910     * MIDI driver:
911     - dispatch bank select (MSB and LSB) messages
912    
913 schoenebeck 1049 * audio driver:
914     - the ALSA audio output driver parameters now reflect the correct
915     parameter value ranges for the respective selected sound card
916     (patch by Till Wimmer, a bit fixed and extended)
917    
918 persson 951 * Gigasampler format engine:
919     - if a filter is used and EG2 finishes before EG1, let the voice
920     die when EG2 has finished (this fixes a problem with clicks and
921     voice starvation for some gigs)
922 persson 1038 - playback is no longer disabled during instrument loading
923     - all notes playing on a channel that changes its instrument keep
924     playing with the old instrument until they get a note off
925     command
926 persson 1039 - EG fix: a release value of zero could cause noises or crash
927 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
928 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
929     above max sustain level, which means that there is a decay phase
930     even if sustain is 100%
931 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
932     noises or crashes
933 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
934 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
935     supplied to the configure script (fixes #46)
936 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
937     instead of a fix value
938 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
939     127 (solo mode) only kill voices if the respective mode really
940     changed
941 persson 951
942 schoenebeck 1244 * LSCP server:
943     - fixed compile time error for old Bison versions
944     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
945 schoenebeck 1245 - parser now supports extended ASCII character set
946     (up to ASCII code 255, i.e. includes now umlauts and accents)
947     - filename arguments in LSCP commands now allow to use escape
948     sequences, that is directly literal as one of: \', \", \\, \n, \r,
949     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
950     code value like \xf2) (fixes bug #24)
951 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
952     least one of their text-based parameters (i.e. name, description):
953     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
954     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
955     "SET DB_INSTRUMENT_DIRECTORY NAME",
956     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
957     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
958     "FIND DB_INSTRUMENT_DIRECTORIES"
959 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
960     occured, the unexpected character and the actually expected, possible
961     character(s), the latter only if less than 5 possibilities)
962 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
963     settings
964 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
965     of strings were treated as being one string containing commas
966     (fixes #57)
967 schoenebeck 1244
968 iliev 959 * Bug fixes:
969     - fixed crash occurring on certain LSCP scripts (Bug 39)
970 persson 1038 - another thread safety fix for lscp "load engine" and "set
971     channel audio output device"
972 iliev 1283 - fixed a crash which occurs when reassigning the same engine
973     on a sampler channel with connected MIDI device
974 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
975     device connected to a sampler channel to number less then or equal
976     to the index of the port to which the sampler channel is connected.
977 iliev 1296 - The previous bindings were not been disconnected when altering
978     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
979     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
980 iliev 1297 - The active stream/voice count statistic was incorrect.
981 iliev 1298 - notification events were not been sent for some sampler
982     channel changes
983 iliev 1305 - added default min and max values to restrict the number of allowed
984     audio output channels and MIDI input ports
985 iliev 1306 - the connection to the PCM interface is now closed when destroying
986     an audio output device
987 schoenebeck 1332 - files with slash in their path or filename could not be loaded
988 iliev 959
989 schoenebeck 1221 * test cases:
990     - updated and fixed (haven't been touched in a while)
991    
992 schoenebeck 937 Version 0.4.0 (24 November 2006)
993 persson 696
994 schoenebeck 697 * packaging changes:
995 capela 868 - changed deprecated copyright attribute to license; added ldconfig
996     to post-(un)install steps; added devel package for liblinuxsampler;
997     to linuxsampler.spec (RPM)
998 schoenebeck 697 - install necessary development header files for allowing 3rd party
999     applications to link against liblinuxsampler
1000     - liblinuxsampler's API documentation can be generated with 'make docs'
1001     (Doxygen required)
1002 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
1003     implementation (currently either an integer math solution or a
1004     di-harmonic approximation), automatic detection can be overriden
1005     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1006     configure script argument though (mandatory for cross-compilation)
1007 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
1008     provided some on his own (as CXXFLAGS)
1009 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
1010     messages
1011 schoenebeck 852 - added compile time options to allow disabling the various audio and
1012     MIDI drivers
1013 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
1014     (patch by Ebrahim Mayat)
1015 schoenebeck 697
1016 persson 696 * Gigasampler format engine:
1017 schoenebeck 738 - extensive synthesis optimization
1018     (reimplementation of EGs and LFO(s), removed synthesis parameter
1019     prerendering and the synthesis parameter matrix in general, splitting
1020     each audio fragment into subfragments now where each subfragment uses
1021 persson 830 constant pitch and filter coefficients. The volume coefficient is
1022     linearly interpolated inside a subfragment, unless
1023     --disable-interpolate-volume is set.)
1024 persson 696 - fine tuning of the EG modulation parameters
1025 persson 729 - improved filter cutoff calculation by adding support for the
1026     following gig parameters: Cutoff freq (used when no cutoff
1027     controller is defined), Control invert, Minimum cutoff, Velocity
1028 persson 791 curve and Velocity range. The keyboard tracking now scales
1029     cutoff frequency instead of resonance.
1030 persson 877 - added support for gig parameter Resonance.
1031 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
1032 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1033     which can be overridden with --enable-global-attenuation
1034 persson 783 - EG fixes: made the length of "attack hold" stage more
1035     accurate. Release stage can now start before attack stage
1036 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
1037     time now has a minimal value to prevent clicks.
1038 persson 799 - fixed pitch changes larger than one octave
1039 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1040     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1041     all modes can be altered via standard GM messages, that is CC5 for
1042     altering portamento time, CC65 for enabling / disabling portamento
1043     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1044 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1045     parameter) and crossfade
1046 persson 831 - added support for the "attenuation controller threshold" gig
1047     parameter
1048 persson 832 - added smoothing of volume changes caused by control change
1049     messages
1050 persson 865 - sample loop parameters are now taken from the DimensionRegion
1051     instead of the wave chunk
1052     - fixed keyswitching for v3 gigs with a number of keyswitch splits
1053     not equal to a power of two
1054 persson 877 - reimplementation of the filter algorithm. The new filter is more
1055     accurate and supports all gig filter types, including bandreject
1056     and lowpass turbo.
1057 persson 903 - real support for 24 bit samples - samples are not truncated to
1058     16 bits anymore
1059     - support for aftertouch (channel pressure, not polyphonic
1060     aftertouch)
1061 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
1062     amplifying from 0)
1063 persson 696
1064 schoenebeck 711 * LSCP server:
1065     - fixed application exit on broken pipe error (fixes bug #20)
1066 iliev 793 - fixed the notification messages delay due to lack of
1067     network activity (fixes bug #26)
1068 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
1069     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1070 schoenebeck 711
1071 schoenebeck 838 * audio driver:
1072     - added aRts audio output driver (by no means RT safe)
1073    
1074 schoenebeck 775 * MIDI driver:
1075     - fixed legacy sysex code which caused dispatching of MIDI SysEx
1076     messages several times instead of once
1077 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
1078     for events (i.e. for offline rendering based MIDI drivers)
1079 persson 922 - added checks for bad MIDI data
1080 schoenebeck 775
1081 schoenebeck 900 * linuxsampler application:
1082     - show available sampler engine types on startup
1083    
1084 schoenebeck 705 * general changes:
1085     - support for muting sampler channels and solo mode of the same, two new
1086     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1087     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1088     introduced for this, the behavior is the same like on a mixer console
1089 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1090     --enable-process-muted-channels which can be used to enable the
1091     processing of muted channels.
1092 iliev 777 - support for sostenuto pedal
1093 iliev 779 - support for monitoring the total number of active voices
1094 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1095     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1096 persson 835 - fixed some memory management errors
1097 persson 841 - fixed some concurrency problems that could lead to crashes when
1098     LSCP commands were executed
1099 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
1100     sampler channel (fixes bug #36)
1101 schoenebeck 705
1102 schoenebeck 692 Version 0.3.3 (15 July 2005)
1103 schoenebeck 686
1104     * packaging changes:
1105     - fixed compilation with gcc 4.0
1106    
1107 schoenebeck 687 * Gigasampler format engine:
1108     - LFO preprocessing was performed even though the respective LFO was
1109     disabled by the instrument patch (minor efficiency fix)
1110 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1111     for volume ramp downs in the same fragment (needed for current voice
1112     stealing implementation) then simply inform the user with a warning
1113     about possible click sounds and reduce the volume ramp down
1114     appropriately instead of cancelling the audio device connection
1115 schoenebeck 687
1116 schoenebeck 677 Version 0.3.2 (24 June 2005)
1117 schoenebeck 609
1118     * packaging changes:
1119     - updated autotools build files to compile on OS X
1120     (conditional compilation of CoreMIDI and MidiShare drivers)
1121 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
1122     './configure --disable-asm' (definitely not recommended)
1123 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
1124     - require automake (>= 1.5) for 'make -f Makefile.cvs'
1125     (due to 'dist-bzip2' automake option)
1126 schoenebeck 649
1127     * Gigasampler format engine:
1128     - support for the gig parameters for "release velocity response" curves
1129     - fine tuning of the EGADSR envelope
1130     - volume of release triggered samples now depends on note-on velocity,
1131     note length and gig parameter "release trigger decay" instead of
1132     note-off velocity.
1133 schoenebeck 663 - revised voice stealing
1134     (fixes crash and endless loop caused by voice stealing)
1135 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
1136 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
1137     instead of when the respective voice is actually launched
1138     (fixes undefined behavior if stolen voices belonged to a key group -
1139     this case was followed by a "killed voice survived" error message)
1140 schoenebeck 669 - fixed minor issue with null/silence samples
1141     (those stole voices even though they don't need a voice at all which
1142     resulted in "voice stealing didn't work out" messages)
1143 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
1144     instrument or audio output device change
1145 schoenebeck 654
1146 schoenebeck 620 * LSCP server:
1147 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1148 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
1149 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
1150 schoenebeck 609
1151 schoenebeck 668 * linuxsampler application:
1152     - added command line parameters --lscp-addr and --lscp-port to override
1153     default IP address and port of LSCP server
1154    
1155 schoenebeck 579 Version 0.3.1 (24 May 2005)
1156    
1157     * initial release
