File size: 57817 byte(s)
* ScriptVM (WIP): started to integrate real-time instrument script
  support into the sampler engine implementations. The code is
  shared among all sampler engines, however currently only the gig
  file format supports storing instrument scripts (as LinuxSampler
  extension to the original GigaStudio 4 file format).
* gig engine: Added support for loading instrument scripts from .gig
  files.
* ScriptVM (WIP): Implemented built-in script variables %CC, $CC_NUM,
  $EVENT_NOTE, $EVENT_VELOCITY, $VCC_MONO_AT, $VCC_PITCH_BEND.
* ScriptVM (WIP): Implemented execution of script event handler "init".
* ScriptVM (WIP): Implemented execution of script event handler
  "controller".
* Bumped version (1.0.0.svn42).

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
115     - made round robin use a counter for each region instead of each
116     key
117 persson 2382 - bugfix: pitch LFO controller "internal+aftertouch" was broken
118     - bugfix: filter keyboard tracking was broken
119     - filter performance fix (an unnecessary copy was made of the
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.

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

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

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

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

607     instrument database compilable
608 schoenebeck 1930 - added instrument database support on Windows
609     works with both standalone mode and VST plugin.
610     the instruments DB file is located in
611     %USERPROFILE%\.linuxsampler\instruments.db which allows different

616 iliev 1603
617 persson 1644 * Gigasampler format engine:

622 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
623     enough for piano gigs with pedal noise samples
624 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
625     respective FX send MIDI controller was used
626 schoenebeck 1724 - added support for GM global device volume SysEx message
627 schoenebeck 1762 (can be selected at compile time to either apply globally to the

629     connected to the respective MIDI input port the SysEx message arrived
630     on)
631 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
632     sometimes wrongly killed in the same buffer, causing no sound to
633     be played
634 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
635     which is usally used to switch a part between chromatic sounds and
636     drumkit sounds (as opposed to their common default setting of MIDI
637     part 10 being a drumkit part and all other ones chromatic parts), in
638     LS however one can switch between the first 16 MIDI instrument maps
639     defined for the sampler
640 persson 1764 - made it possible to create multiple sample channels even if the
641     audio thread isn't running

645     sampler engine anymore
646     - re-cache samples in case they were changed by an instrument editor,
647     e.g. when a sample was added while playing (#82)
648 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
649     same time stamp as the voice's note-on event and occured both in the

651 persson 1858 - added support for the "fine tune" and "pitch bend range"
652     instrument-level gig parameters
653     - fixed minor artifacts in pitch bend handling

655 persson 1862 - allow gig files to use unlimited downward pitch shifting
656     - added a limit check for upward pitch shifting
657 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
658     note was silent
659 persson 1923 - fixed crash happening when a pitch bend event arrived at the
660     same time a new instrument was loading
661 persson 1644
662 schoenebeck 1687 * LSCP server:
663     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
664     react on MIDI data arriving on certain sampler channels (so far only
665     Note-On and Note-Off events are sent via this LSCP event)
666 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
667     react on MIDI data arriving on certain MIDI input devices (so far only

674     KEY_BINDINGS and KEYSWITCH_BINDINGS
675 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
676     was incorrect
677 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
678 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
679     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
680     be triggered respectively
681     - added new LSCP command "SET STREAMS" to globally alter the maximum
682     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
683     which will be triggered respectively
684 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
685     a gigedit file dialog is opened)

704     - fixed possible compilation error when sqlite is not present
705 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
706 iliev 1847 - fixed crash when changing the audio output device of a sampler
707     channel with loaded instrument and start playing notes
708 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
709 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
710     PowerPC, which probably could cause crashes on that platform
711 persson 1889 - fixed a memory management error which could cause a crash when a
712     plugin was unloaded
713 persson 1896 - bugfix: two private structs had the same name, which could cause
714     problems if the linker chose the wrong constructor
715 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
716     Windows

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