* Instrument editor interface: Changed instrument editor plugin interface,
providing additional informations like the EngineChannel for which the
instrument editor was spawned for. This allows the instrument editors to
interact more actively with the sampler.
* Bumped version (1.0.0.svn60).

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

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

308 persson 2045 - VST bugfix: If the host called resume() before and after
309     changing sample rate or block size, the number of channels was
310     incorrectly set to two. This caused silence in Cubase 5.
311 persson 2165 - save engine type (gig, sfz or sf2) in plugin state
312     - VST: when opening Fantasia, look for both 32 and 64 bit Java on

325     - thread safety fixes for the instrument loading thread
326 persson 2343 - LV2: use the new lv2 package if present
327 persson 2347 - VST: try to open Fantasia automatically on Linux and Mac too (on
328     Linux, the Fantasia jar should be placed in <prefix>/share/java)
329     - VST: fixed crashes on Linux Ardour and EnergyXT

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

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

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

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

614 persson 1748 jack_client_new
615 iliev 1829 - added (experimental) CoreAudio driver
616 persson 1888 - applied old fixes to the ASIO driver that were included in the
617     previous binary release but accidentally never committed to CVS
618     (fixes #117)
619 persson 1889 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
620     win64)

656     instrument database compilable
657 schoenebeck 1930 - added instrument database support on Windows
658     works with both standalone mode and VST plugin.
659     the instruments DB file is located in
660     %USERPROFILE%\.linuxsampler\instruments.db which allows different
661     databases for each windows user
662     if no DB is present it automatically creates the .linuxsampler subdir
663     and then creates an empty DB
664 persson 1943 - fixed recursive import, which was broken on Windows
665 iliev 1603
666 persson 1644 * Gigasampler format engine:
667     - fixed a memory leak that could happen when a channel was deleted
668     while notes were playing
669 persson 1646 - made it possible to load an instrument even if the audio thread
670     isn't running
671 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
672     enough for piano gigs with pedal noise samples
673 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
674     respective FX send MIDI controller was used
675 schoenebeck 1724 - added support for GM global device volume SysEx message
676 schoenebeck 1762 (can be selected at compile time to either apply globally to the
677     whole sampler [default] or only to the sampler channels that are
678     connected to the respective MIDI input port the SysEx message arrived
679     on)
680 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
681     sometimes wrongly killed in the same buffer, causing no sound to
682     be played
683 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
684     which is usally used to switch a part between chromatic sounds and
685     drumkit sounds (as opposed to their common default setting of MIDI
686     part 10 being a drumkit part and all other ones chromatic parts), in
687     LS however one can switch between the first 16 MIDI instrument maps
688     defined for the sampler
689 persson 1764 - made it possible to create multiple sample channels even if the
690     audio thread isn't running

694     sampler engine anymore
695     - re-cache samples in case they were changed by an instrument editor,
696     e.g. when a sample was added while playing (#82)
697 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
698     same time stamp as the voice's note-on event and occured both in the
699     same audio fragment cycle (fixes bug #112)
700 persson 1858 - added support for the "fine tune" and "pitch bend range"
701     instrument-level gig parameters
702     - fixed minor artifacts in pitch bend handling

706 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
707     note was silent
708 persson 1923 - fixed crash happening when a pitch bend event arrived at the
709     same time a new instrument was loading
710 persson 1644
711 schoenebeck 1687 * LSCP server:
712     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
713     react on MIDI data arriving on certain sampler channels (so far only
714     Note-On and Note-Off events are sent via this LSCP event)
715 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
716     react on MIDI data arriving on certain MIDI input devices (so far only
717     Note-On and Note-Off events are sent via this LSCP event)
718 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
719     SET DB_INSTRUMENT FILE_PATH
720 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
721     frontends to send MIDI messages to specific sampler channel
722     - added two additional fields to GET FILE INSTRUMENT INFO command -
723     KEY_BINDINGS and KEYSWITCH_BINDINGS
724 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications

726 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
727 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
728     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
729     be triggered respectively
730     - added new LSCP command "SET STREAMS" to globally alter the maximum
731     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
732     which will be triggered respectively
733 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
734     a gigedit file dialog is opened)
735 iliev 1848 - close all connections when LSCPServer is deleted
736 iliev 1882 - hard close of all sockets on exit
737 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
738     driver
739 schoenebeck 1687
740 iliev 1761 * Bug fixes:
741     - fixed a crash which occurs when removing a sampler channel waiting
742     to start instrument loading after another channel
743 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
744     instrument loading in progress (bug #113)
745 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
746     instrument with PERSISTENT load mode
747 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
748     - fixed memory leaks when issuing the following LSCP commands:

750     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
751     GET MIDI_INPUT_DRIVER INFO
752     GET MIDI_INPUT_DRIVER_PARAMETER INFO

754 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
755 iliev 1847 - fixed crash when changing the audio output device of a sampler
756     channel with loaded instrument and start playing notes
757 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
758 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
759     PowerPC, which probably could cause crashes on that platform
760 persson 1889 - fixed a memory management error which could cause a crash when a
761     plugin was unloaded
762 persson 1896 - bugfix: two private structs had the same name, which could cause
763     problems if the linker chose the wrong constructor
764 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
765     Windows

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