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 iliev 2012
107 persson 2043 * Gigasampler format engine:
108     - implemented the "round robin keyboard" dimension
109     - fixed round robin and random dimensions for cases when number of
110     dimension zones is not a power of two
111     - made round robin use a counter for each region instead of each
112     key
113 persson 2382 - bugfix: pitch LFO controller "internal+aftertouch" was broken
114     - bugfix: filter keyboard tracking was broken
115     - filter performance fix (an unnecessary copy was made of the
116     filter parameters in each sub fragment)
117     - handle special case when pan parameter in gig file has max or
118     min value
119 schoenebeck 2396 - Exclusive Groups: don't ever stop voices of the same note,
120     doesn't sound naturally with a drumkit
121 persson 2408 - fixed EG1 modulation when attack or release is zero
122 schoenebeck 2559 - Fixed support for 'aftertouch' attenuation controller.
123 schoenebeck 2565 - Fixed crash that happened with velocity split sounds under certain
124     conditions (see also previous commit on libgig).

323     - VST: fixed crashes on Linux Ardour and EnergyXT
324 persson 2354 - DSSI bugfix: it wasn't possible to change engine type. The MIDI
325     port and audio channel routing for DSSI plugins are now visible.

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

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

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

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

591     instrument database compilable
592 schoenebeck 1930 - added instrument database support on Windows
593     works with both standalone mode and VST plugin.
594     the instruments DB file is located in
595     %USERPROFILE%\.linuxsampler\instruments.db which allows different

597     if no DB is present it automatically creates the .linuxsampler subdir
598     and then creates an empty DB

600 iliev 1603
601 persson 1644 * Gigasampler format engine:

604 persson 1646 - made it possible to load an instrument even if the audio thread
605     isn't running
606 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
607     enough for piano gigs with pedal noise samples
608 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
609     respective FX send MIDI controller was used
610 schoenebeck 1724 - added support for GM global device volume SysEx message
611 schoenebeck 1762 (can be selected at compile time to either apply globally to the

613     connected to the respective MIDI input port the SysEx message arrived
614     on)
615 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
616     sometimes wrongly killed in the same buffer, causing no sound to
617     be played
618 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
619     which is usally used to switch a part between chromatic sounds and
620     drumkit sounds (as opposed to their common default setting of MIDI
621     part 10 being a drumkit part and all other ones chromatic parts), in
622     LS however one can switch between the first 16 MIDI instrument maps
623     defined for the sampler
624 persson 1764 - made it possible to create multiple sample channels even if the
625     audio thread isn't running

629     sampler engine anymore
630     - re-cache samples in case they were changed by an instrument editor,
631     e.g. when a sample was added while playing (#82)
632 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
633     same time stamp as the voice's note-on event and occured both in the
634     same audio fragment cycle (fixes bug #112)
635 persson 1858 - added support for the "fine tune" and "pitch bend range"
636     instrument-level gig parameters
637     - fixed minor artifacts in pitch bend handling
638 schoenebeck 1860 - added support for GS Reset SysEx message
639 persson 1862 - allow gig files to use unlimited downward pitch shifting
640     - added a limit check for upward pitch shifting
641 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
642     note was silent
643 persson 1923 - fixed crash happening when a pitch bend event arrived at the
644     same time a new instrument was loading
645 persson 1644
646 schoenebeck 1687 * LSCP server:
647     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
648     react on MIDI data arriving on certain sampler channels (so far only
649     Note-On and Note-Off events are sent via this LSCP event)
650 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
651     react on MIDI data arriving on certain MIDI input devices (so far only

658     KEY_BINDINGS and KEYSWITCH_BINDINGS
659 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
660     was incorrect
661 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
662 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
663     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
664     be triggered respectively
665     - added new LSCP command "SET STREAMS" to globally alter the maximum
666     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
667     which will be triggered respectively
668 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
669     a gigedit file dialog is opened)
670 iliev 1848 - close all connections when LSCPServer is deleted
671 iliev 1882 - hard close of all sockets on exit

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