Fri Apr 22 15:37:45 2016 UTC (7 years, 11 months ago) by schoenebeck
File size: 63632 byte(s)
* Instrument script classes now exported with the liblinuxsampler C++ API.
* Added new API method ScriptVM::syntaxHighlighting() which provides
  a convenient syntax highlighting backend for external instrument
  script editor applications.
* Bumped version (2.0.0.svn5).

1 persson 2837 Version SVN trunk (?)
2    
3 persson 2856 * SFZ format engine:
4     - added support for <global>, <master> and #define (patch by Alby M)
5    
6 persson 2837 * general changes:
7     - fixed printf type errors (mostly in debug messages)
8 persson 2840 - use unique_ptr instead of auto_ptr when building with C++11
9 schoenebeck 2871 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
10     allowing to sort data efficiently in real-time safe manner.
11     - RTList class: added methods for moving/inserting elements to arbitrary
12     position within a list.
13     - RTList class: added method fromPtr() for creating an Iterator object from
14     a raw element pointer.
15     - Attempt to partly fix resetting engine channels vs. resetting engine, an
16     overall cleanup of the Reset*(), ConnectAudioDevice(),
17     DisconnectAudioDevice() API methods would still be desirable though,
18     because the current situation is still inconsistent and error prone.
19 schoenebeck 2879 - Active voices are now internally grouped to "Note" objects, instead of
20     being directly assigned to a keyboard key. This allows more fine graded
21     processing of voices, which is i.e. required for certain instrument
22     script features.
23 persson 2837
24 schoenebeck 2866 * packaging changes:
25     - removed unnecessary dependency to libuuid
26     (originated by libgig's usage of it)
27 schoenebeck 2884 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
28     auto detect whether it (sh/c)ould output its messages in color.
29 schoenebeck 2866
30 schoenebeck 2871 * Real-time instrument scripts:
31     - Implemented scheduler for delayed MIDI events and for suspended scripts.
32     - Built-in script function "wait()": implemented support for function's
33     "duration-us" argument, thus scripts using this function are now
34     correctly resumed after the requested amount of microseconds.
35     - Built-in script function "play_note()": implemented support for
36     function's "duration-us" argument, thus notes triggered with this
37     argument are now correctly released after the requested amount of
38     microseconds.
39     - Fix: script events were not cleared when engine channel was reset,
40     potentially causing undefined behavior.
41     - Fixed crash which happened when trying to reference an undeclared
42     variable.
43 schoenebeck 2879 - Built-in script function "play_note()": Added support for passing
44     special value -1 for "duration-us" argument, which will cause the
45     triggered note to be released once the original note was released.
46 schoenebeck 2885 - Instrument script classes now exported with the liblinuxsampler C++ API.
47     - Added new API method ScriptVM::syntaxHighlighting() which provides
48     a convenient syntax highlighting backend for external instrument
49     script editor applications.

89     in order to get rid of warnings from automake 1.14
90 persson 2382
91 persson 2086 * general changes:
92 iliev 2012 - Refactoring: moved the independent code from
93     the Gigasampler format engine to base classes
94 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
95     respective profiling code is currently broken
96 schoenebeck 2053 - Introduced support for optional environment variable
97     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
98     where the sampler shall look for instrument editor plugins
99     (patch by Luis Garrido, slightly modified).
100 schoenebeck 2121 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
101     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
102     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
103     note (in this implementation of the sampler its simply hard routed to
104     the 1st effect send of the sampler channel, no matter what the actual
105     effect type is)
106     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
107     note (in this implementation of the sampler its simply hard routed to
108     the 2nd effect send of the sampler channel, no matter what the actual
109     effect type is)
110 schoenebeck 2124 - implemented support for internal LADSPA effects
111 schoenebeck 2140 - raised limit of program change queue from 100 to 512
112     (as suggested by Alex Stone)
113 iliev 2223 - implemented sine LFO, pulse LFO and saw LFO
114 iliev 2296 - experimental support for per voice equalization
115 iliev 2306 - added command line option --exec-after-init
116 schoenebeck 2330 - Introduced new C++ API method:
117     EngineChannel::InstrumentFileName(int index)
118     allowing to retrieve the whole list of files used for the loaded
119     instrument on an engine channel (a.k.a. part). Some GigaStudio
120     instruments for example are splitted over several files like
121     "Foo.gig", "Foo.gx01", "Foo.gx02", ...
122 schoenebeck 2375 - Added new C++ API method Sampler::GetGlobalMaxVoices().
123     - Added new C++ API method Sampler::GetGlobalMaxStreams().
124     - Added new C++ API method Sampler::SetGlobalMaxVoices().
125     - Added new C++ API method Sampler::SetGlobalMaxStreams().
126 schoenebeck 2377 - Various "const" and "restrict" optimizations.
127 persson 2382 - all engines: add pan CC value to instrument pan parameter before
128     applying panning, instead of using two separate pan functions in
129     series (#182)
130 persson 2427 - added a lock guard class for exception safe mutex handling and
131     used it everywhere appropriate
132 schoenebeck 2448 - Immediately apply scale tuning changes to active voices.
133     - Exposed scale tuning to C++ API (along to the already existing standard
134     SysEx way).
135 persson 2452 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
136     and broken for ppc64. (Seq_cst loads and stores are actually not
137     used in LS, so the bug wasn't noticable.)
138     - lsatomic.h: added ARMv7 support
139 schoenebeck 2500 - Added support for multiple MIDI input ports per sampler channel (and
140     added various new C++ methods for this new feature / design change, old
141     C++ API methods for managing SamplerChannel's MIDI inputs are now marked
142     as deprecated but are still there and should provide full behavior
143     backward compatibility).
144     - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
145     unsafe and caused compilation error with clang 2.x).
146 schoenebeck 2506 - Bugfix: only process the latest MIDI program change event.
147 schoenebeck 2515 - Introducing the LSCP shell, which provides convenient control of the
148     sampler from the command line by providing LSCP aware features.
149 schoenebeck 2521 - VirtualMidiDevice: Added support for program change.
150     - VirtualMidiDevice: Added support for bank select (MSB & LSB).
151     - VirtualMidiDevice: Added support for pitch bend.
152 schoenebeck 2559 - Aftertouch: extended API to explicitly handle channel pressure and
153     polyphonic key pressure events (so far polyphonic pressure was not
154     supported at all, and channel pressure was rerouted as CC128 but not
155     used so far).
156 schoenebeck 2594 - Added initial support for real-time instrument scripts. The script VM
157     code is shared by all sampler engine implemementations, however only the
158     gig file format currently provides support for storing instrument scripts
159     (as LinuxSampler extension to the original GigaStudio 4 format).
160 iliev 2012
161 persson 2043 * Gigasampler format engine:
162     - implemented the "round robin keyboard" dimension
163     - fixed round robin and random dimensions for cases when number of

168     - bugfix: filter keyboard tracking was broken
169     - filter performance fix (an unnecessary copy was made of the
170     filter parameters in each sub fragment)
171     - handle special case when pan parameter in gig file has max or
172     min value
173 schoenebeck 2396 - Exclusive Groups: don't ever stop voices of the same note,
174     doesn't sound naturally with a drumkit

583     (fixes #208)
584 schoenebeck 2523 - Fixed bug in LSCP grammar definition which caused a statement like
585     "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
586     practically irrelevant, however it caused problems with the new LSCP
587     shell's auto completion feature).
588 schoenebeck 2672 - Fixed MIDI program change messages being ignored if quickly executed
589     after each other (fixes #231).

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

696 persson 1924 - made program change handling in MIDI thread real-time safe by
697     moving the logic to a non-RT thread
698 persson 1951 - fixed minor memory leak in ALSA driver
699 persson 1651
700 schoenebeck 1604 * instruments database:
701 iliev 1603 - avoid time consuming samples scanning when adding instruments
702     to the instruments database
703 iliev 1727 - added support for handling lost files in the instruments database
704 iliev 1781 - Implemented option for adding instruments in separate directories
705     in the instruments database
706     (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
707 persson 1908 - work-around for missing fnmatch function on Windows to make
708     instrument database compilable
709 schoenebeck 1930 - added instrument database support on Windows
710     works with both standalone mode and VST plugin.
711     the instruments DB file is located in
712     %USERPROFILE%\.linuxsampler\instruments.db which allows different
713     databases for each windows user
714     if no DB is present it automatically creates the .linuxsampler subdir
715     and then creates an empty DB
716 persson 1943 - fixed recursive import, which was broken on Windows
717 iliev 1603
718 persson 1644 * Gigasampler format engine:
719     - fixed a memory leak that could happen when a channel was deleted
720     while notes were playing
721 persson 1646 - made it possible to load an instrument even if the audio thread
722     isn't running
723 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
724     enough for piano gigs with pedal noise samples
725 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
726     respective FX send MIDI controller was used
727 schoenebeck 1724 - added support for GM global device volume SysEx message
728 schoenebeck 1762 (can be selected at compile time to either apply globally to the
729     whole sampler [default] or only to the sampler channels that are
730     connected to the respective MIDI input port the SysEx message arrived
731     on)
732 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
733     sometimes wrongly killed in the same buffer, causing no sound to
734     be played
735 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
736     which is usally used to switch a part between chromatic sounds and
737     drumkit sounds (as opposed to their common default setting of MIDI
738     part 10 being a drumkit part and all other ones chromatic parts), in
739     LS however one can switch between the first 16 MIDI instrument maps
740     defined for the sampler
741 persson 1764 - made it possible to create multiple sample channels even if the
742     audio thread isn't running
743 persson 1844 - fixed crash when removing channel with active voices (#116)
744 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
745     un-cache the respective sample if it's really not used by any
746     sampler engine anymore
747     - re-cache samples in case they were changed by an instrument editor,
748     e.g. when a sample was added while playing (#82)
749 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
750     same time stamp as the voice's note-on event and occured both in the
751     same audio fragment cycle (fixes bug #112)
752 persson 1858 - added support for the "fine tune" and "pitch bend range"
753     instrument-level gig parameters
754     - fixed minor artifacts in pitch bend handling
755 schoenebeck 1860 - added support for GS Reset SysEx message
756 persson 1862 - allow gig files to use unlimited downward pitch shifting
757     - added a limit check for upward pitch shifting
758 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
759     note was silent
760 persson 1923 - fixed crash happening when a pitch bend event arrived at the
761     same time a new instrument was loading
762 persson 1644
763 schoenebeck 1687 * LSCP server:
764     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
765     react on MIDI data arriving on certain sampler channels (so far only
766     Note-On and Note-Off events are sent via this LSCP event)
767 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
768     react on MIDI data arriving on certain MIDI input devices (so far only
769     Note-On and Note-Off events are sent via this LSCP event)
770 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
771     SET DB_INSTRUMENT FILE_PATH
772 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
773     frontends to send MIDI messages to specific sampler channel
774     - added two additional fields to GET FILE INSTRUMENT INFO command -
775     KEY_BINDINGS and KEYSWITCH_BINDINGS
776 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
777     was incorrect
778 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
779 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
780     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
781     be triggered respectively
782     - added new LSCP command "SET STREAMS" to globally alter the maximum
783     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
784     which will be triggered respectively
785 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
786     a gigedit file dialog is opened)
787 iliev 1848 - close all connections when LSCPServer is deleted
788 iliev 1882 - hard close of all sockets on exit
789 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
790     driver
791 schoenebeck 1687
792 iliev 1761 * Bug fixes:
793     - fixed a crash which occurs when removing a sampler channel waiting
794     to start instrument loading after another channel
795 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
796     instrument loading in progress (bug #113)
797 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
798     instrument with PERSISTENT load mode
799 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
800     - fixed memory leaks when issuing the following LSCP commands:
801     GET AUDIO_OUTPUT_DRIVER INFO
802     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
803     GET MIDI_INPUT_DRIVER INFO
804     GET MIDI_INPUT_DRIVER_PARAMETER INFO
805     - fixed possible compilation error when sqlite is not present
806 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
807 iliev 1847 - fixed crash when changing the audio output device of a sampler
808     channel with loaded instrument and start playing notes
809 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
810 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
811     PowerPC, which probably could cause crashes on that platform
812 persson 1889 - fixed a memory management error which could cause a crash when a
813     plugin was unloaded
814 persson 1896 - bugfix: two private structs had the same name, which could cause
815     problems if the linker chose the wrong constructor
816 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
817     Windows
818 iliev 1761
819    
820 schoenebeck 1560 Version 0.5.1 (6 December 2007)
821 schoenebeck 1454
822     * packaging changes:
823     - added autoconf checks for pthread library
824     - added autoconf check for pthread bug found on certain NPTL-enabled
825     glibc versions (see Gentoo bug report #194076)
826 senoner 1502 - added autoconf checks for MS Windows
827 schoenebeck 1454
828 persson 1455 * general changes:
829     - bugfix: the thread used by an editor plugin didn't die when the
830     editor closed
831 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
832     out all the space. operator--() did not apply size_mask after
833     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
834     order to avoid problems with the _NonVolatileReader functions.
835     - bugfix: Stream.h: added a missing divide by BytesPerSample in
836     GetWriteSpace(). Since this function is currently only used in
837     the stream's qsort() compare function, it didn't trigger any
838     bugs.
839     - Resampler.h, Synthesizer.h: cubic interpolation now works in
840     24bit mode too. Faster method to read 24bit words on little
841     endian machines (x86): replaced 3 byte reads + shifts with a 1
842     unaligned 32bit read and shift
843     - experimental support for MS Windows (MIDI input via MME, AUDIO
844     output via ASIO)
845     - made handling of SIGINT signal (Ctrl-C) a bit more robust
846 iliev 1541 - support for monitoring the total number of active disk streams
847     (new LSCP commands: GET TOTAL_STREAM_COUNT,
848     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
849 persson 1455
850 senoner 1500 * AUDIO driver:
851 persson 1534 - added Windows ASIO low latency audio driver
852 senoner 1500
853 senoner 1485 * MIDI driver:
854 schoenebeck 1495 - added MME Windows MIDI driver
855 senoner 1485
856 schoenebeck 1471 * LSCP server:
857     - added support for Windows style path / filenames, however with
858     forward slash path separators instead of backslash
859     (i.e. "C:/foo/bar.gig")
860 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
861     apostrophes as well
862 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
863     "LIST FILE INSTRUMENTS <file>" and
864     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
865     about an arbitrary instrument file on the system where the sampler is
866     running on
867 schoenebeck 1471
868 schoenebeck 1424 Version 0.5.0 (15 October 2007)
869 schoenebeck 947
870 schoenebeck 1065 * packaging changes:
871 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
872     API header files anymore
873 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
874     the Doxygen API documentation (explicitly listed in Doxyfile.in)
875 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
876     capable to execute our autoconf environment, thus no need anymore
877     to maintain the compile time configuration file (osx/version.h) for
878     OSX manually (patch by Toshi Nagata)
879 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
880     parameters
881 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
882     C++ API header files, all implementation internal global definitions
883     are now in global_private.h
884     - atomic.h is not exposed to the C++ API anymore
885     - no need to include config.h anymore for using LS's API header files
886     - fixed warnings in API doc generation
887 schoenebeck 1065
888 schoenebeck 947 * general changes:
889     - replaced the old, confusing MIDI program change mechanism by a
890     flexible MIDI instrument mapper which allows to map arbitrary
891 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
892 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
893     loaded on the respective channel when such MIDI program change
894     messages arrive, beside that, each entry allows to define a life-time
895     strategy for the instrument, so the user can define whether the
896     instrument should i.e. be permanently loaded (to be able to switch
897     quickly among sounds) or i.e. loaded just on demand when the
898     respective program change arrives (to safe RAM space), as well as a
899     global volume factor for each entry, so the user can adjust the volume
900     dynamic of his mapped instrument collection without having to modify
901 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
902     MIDI instrument maps and assign each sampler channel individually
903     a certain map, so that i.e. separation of normal instruments and
904     drumkits is possible
905 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
906     MIDI instrument maps, MIDI instruments, FX sends, global volume.
907 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
908     due to a constant size RingBuffer FIFO which is now replaced by a
909     dynamic (unlimited) size std::list FIFO
910 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
911     output channels for being processed by external effect processors
912     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
913     controllers
914 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
915 iliev 1130 - Implemented new, improved notification system
916 schoenebeck 1149 - fixed compilation errors regarding OSX
917     (patch by Toshi Nagata)
918 iliev 1161 - implemented instruments database
919 iliev 1345 - added support for escape sequences to the instruments database
920 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
921     within the sampler's process (by using instrument editor plugins),
922     you'll notice the new "Registered instrument editors:" message on
923 schoenebeck 1407 startup, added a new LSCP command:
924     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
925 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
926     given sampler channel, the plugin path can be overridden at compile
927     time with ./configure --enable-plugin-dir=/some/dir
928 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
929     in the sampler's process to safely edit instruments while playing
930     without a crash (hopefully) by either suspending single regions
931     wherever possible or if unavoidable whole engine(s)
932 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
933     policy and priority on thread level, set a minimum stack size for
934     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
935     threads simply inherited properties of starting thread instead of
936     setting their own policy and priority
937 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
938     main process did not wait for the stack trace process to finish
939     its output
940 persson 1248 - fixed some minor memory leaks
941 schoenebeck 1259 - reenabled assembly features support, at the moment only for
942     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
943 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
944     register, to avoid relocations in the text segment at runtime)
945 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
946 schoenebeck 947
947     * MIDI driver:
948     - dispatch bank select (MSB and LSB) messages
949    
950 schoenebeck 1049 * audio driver:
951     - the ALSA audio output driver parameters now reflect the correct
952     parameter value ranges for the respective selected sound card
953     (patch by Till Wimmer, a bit fixed and extended)
954    
955 persson 951 * Gigasampler format engine:
956     - if a filter is used and EG2 finishes before EG1, let the voice
957     die when EG2 has finished (this fixes a problem with clicks and
958     voice starvation for some gigs)
959 persson 1038 - playback is no longer disabled during instrument loading
960     - all notes playing on a channel that changes its instrument keep
961     playing with the old instrument until they get a note off
962     command
963 persson 1039 - EG fix: a release value of zero could cause noises or crash
964 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
965 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
966     above max sustain level, which means that there is a decay phase
967     even if sustain is 100%
968 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
969     noises or crashes
970 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
971 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
972     supplied to the configure script (fixes #46)
973 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
974     instead of a fix value
975 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
976     127 (solo mode) only kill voices if the respective mode really
977     changed
978 persson 951
979 schoenebeck 1244 * LSCP server:
980     - fixed compile time error for old Bison versions
981     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
982 schoenebeck 1245 - parser now supports extended ASCII character set
983     (up to ASCII code 255, i.e. includes now umlauts and accents)
984     - filename arguments in LSCP commands now allow to use escape
985     sequences, that is directly literal as one of: \', \", \\, \n, \r,
986     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
987     code value like \xf2) (fixes bug #24)
988 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
989     least one of their text-based parameters (i.e. name, description):
990     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
991     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
992     "SET DB_INSTRUMENT_DIRECTORY NAME",
993     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
994     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
995     "FIND DB_INSTRUMENT_DIRECTORIES"
996 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
997     occured, the unexpected character and the actually expected, possible
998     character(s), the latter only if less than 5 possibilities)
999 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
1000     settings
1001 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
1002     of strings were treated as being one string containing commas
1003     (fixes #57)
1004 schoenebeck 1244
1005 iliev 959 * Bug fixes:
1006     - fixed crash occurring on certain LSCP scripts (Bug 39)
1007 persson 1038 - another thread safety fix for lscp "load engine" and "set
1008     channel audio output device"
1009 iliev 1283 - fixed a crash which occurs when reassigning the same engine
1010     on a sampler channel with connected MIDI device
1011 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
1012     device connected to a sampler channel to number less then or equal
1013     to the index of the port to which the sampler channel is connected.
1014 iliev 1296 - The previous bindings were not been disconnected when altering
1015     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1016     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1017 iliev 1297 - The active stream/voice count statistic was incorrect.
1018 iliev 1298 - notification events were not been sent for some sampler
1019     channel changes
1020 iliev 1305 - added default min and max values to restrict the number of allowed
1021     audio output channels and MIDI input ports
1022 iliev 1306 - the connection to the PCM interface is now closed when destroying
1023     an audio output device
1024 schoenebeck 1332 - files with slash in their path or filename could not be loaded
1025 iliev 959
1026 schoenebeck 1221 * test cases:
1027     - updated and fixed (haven't been touched in a while)
1028    
1029 schoenebeck 937 Version 0.4.0 (24 November 2006)
1030 persson 696
1031 schoenebeck 697 * packaging changes:
1032 capela 868 - changed deprecated copyright attribute to license; added ldconfig
1033     to post-(un)install steps; added devel package for liblinuxsampler;
1034     to linuxsampler.spec (RPM)
1035 schoenebeck 697 - install necessary development header files for allowing 3rd party
1036     applications to link against liblinuxsampler
1037     - liblinuxsampler's API documentation can be generated with 'make docs'
1038     (Doxygen required)
1039 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
1040     implementation (currently either an integer math solution or a
1041     di-harmonic approximation), automatic detection can be overriden
1042     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1043     configure script argument though (mandatory for cross-compilation)
1044 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
1045     provided some on his own (as CXXFLAGS)
1046 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
1047     messages
1048 schoenebeck 852 - added compile time options to allow disabling the various audio and
1049     MIDI drivers
1050 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
1051     (patch by Ebrahim Mayat)
1052 schoenebeck 697
1053 persson 696 * Gigasampler format engine:
1054 schoenebeck 738 - extensive synthesis optimization
1055     (reimplementation of EGs and LFO(s), removed synthesis parameter
1056     prerendering and the synthesis parameter matrix in general, splitting
1057     each audio fragment into subfragments now where each subfragment uses
1058 persson 830 constant pitch and filter coefficients. The volume coefficient is
1059     linearly interpolated inside a subfragment, unless
1060     --disable-interpolate-volume is set.)
1061 persson 696 - fine tuning of the EG modulation parameters
1062 persson 729 - improved filter cutoff calculation by adding support for the
1063     following gig parameters: Cutoff freq (used when no cutoff
1064     controller is defined), Control invert, Minimum cutoff, Velocity
1065 persson 791 curve and Velocity range. The keyboard tracking now scales
1066     cutoff frequency instead of resonance.
1067 persson 877 - added support for gig parameter Resonance.
1068 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
1069 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1070     which can be overridden with --enable-global-attenuation
1071 persson 783 - EG fixes: made the length of "attack hold" stage more
1072     accurate. Release stage can now start before attack stage
1073 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
1074     time now has a minimal value to prevent clicks.
1075 persson 799 - fixed pitch changes larger than one octave
1076 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1077     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1078     all modes can be altered via standard GM messages, that is CC5 for
1079     altering portamento time, CC65 for enabling / disabling portamento
1080     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1081 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1082     parameter) and crossfade
1083 persson 831 - added support for the "attenuation controller threshold" gig
1084     parameter
1085 persson 832 - added smoothing of volume changes caused by control change
1086     messages
1087 persson 865 - sample loop parameters are now taken from the DimensionRegion
1088     instead of the wave chunk
1089     - fixed keyswitching for v3 gigs with a number of keyswitch splits
1090     not equal to a power of two
1091 persson 877 - reimplementation of the filter algorithm. The new filter is more
1092     accurate and supports all gig filter types, including bandreject
1093     and lowpass turbo.
1094 persson 903 - real support for 24 bit samples - samples are not truncated to
1095     16 bits anymore
1096     - support for aftertouch (channel pressure, not polyphonic
1097     aftertouch)
1098 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
1099     amplifying from 0)
1100 persson 696
1101 schoenebeck 711 * LSCP server:
1102     - fixed application exit on broken pipe error (fixes bug #20)
1103 iliev 793 - fixed the notification messages delay due to lack of
1104     network activity (fixes bug #26)
1105 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
1106     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1107 schoenebeck 711
1108 schoenebeck 838 * audio driver:
1109     - added aRts audio output driver (by no means RT safe)
1110    
1111 schoenebeck 775 * MIDI driver:
1112     - fixed legacy sysex code which caused dispatching of MIDI SysEx
1113     messages several times instead of once
1114 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
1115     for events (i.e. for offline rendering based MIDI drivers)
1116 persson 922 - added checks for bad MIDI data
1117 schoenebeck 775
1118 schoenebeck 900 * linuxsampler application:
1119     - show available sampler engine types on startup
1120    
1121 schoenebeck 705 * general changes:
1122     - support for muting sampler channels and solo mode of the same, two new
1123     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1124     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1125     introduced for this, the behavior is the same like on a mixer console
1126 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1127     --enable-process-muted-channels which can be used to enable the
1128     processing of muted channels.
1129 iliev 777 - support for sostenuto pedal
1130 iliev 779 - support for monitoring the total number of active voices
1131 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1132     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1133 persson 835 - fixed some memory management errors
1134 persson 841 - fixed some concurrency problems that could lead to crashes when
1135     LSCP commands were executed
1136 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
1137     sampler channel (fixes bug #36)
1138 schoenebeck 705
1139 schoenebeck 692 Version 0.3.3 (15 July 2005)
1140 schoenebeck 686
1141     * packaging changes:
1142     - fixed compilation with gcc 4.0
1143    
1144 schoenebeck 687 * Gigasampler format engine:
1145     - LFO preprocessing was performed even though the respective LFO was
1146     disabled by the instrument patch (minor efficiency fix)
1147 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1148     for volume ramp downs in the same fragment (needed for current voice
1149     stealing implementation) then simply inform the user with a warning
1150     about possible click sounds and reduce the volume ramp down
1151     appropriately instead of cancelling the audio device connection
1152 schoenebeck 687
1153 schoenebeck 677 Version 0.3.2 (24 June 2005)
1154 schoenebeck 609
1155     * packaging changes:
1156     - updated autotools build files to compile on OS X
1157     (conditional compilation of CoreMIDI and MidiShare drivers)
1158 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
1159     './configure --disable-asm' (definitely not recommended)
1160 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
1161     - require automake (>= 1.5) for 'make -f Makefile.cvs'
1162     (due to 'dist-bzip2' automake option)
1163 schoenebeck 649
1164     * Gigasampler format engine:
1165     - support for the gig parameters for "release velocity response" curves
1166     - fine tuning of the EGADSR envelope
1167     - volume of release triggered samples now depends on note-on velocity,
1168     note length and gig parameter "release trigger decay" instead of
1169     note-off velocity.
1170 schoenebeck 663 - revised voice stealing
1171     (fixes crash and endless loop caused by voice stealing)
1172 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
1173 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
1174     instead of when the respective voice is actually launched
1175     (fixes undefined behavior if stolen voices belonged to a key group -
1176     this case was followed by a "killed voice survived" error message)
1177 schoenebeck 669 - fixed minor issue with null/silence samples
1178     (those stole voices even though they don't need a voice at all which
1179     resulted in "voice stealing didn't work out" messages)
1180 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
1181     instrument or audio output device change
1182 schoenebeck 654
1183 schoenebeck 620 * LSCP server:
1184 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1185 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
1186 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
1187 schoenebeck 609
1188 schoenebeck 668 * linuxsampler application:
1189     - added command line parameters --lscp-addr and --lscp-port to override
1190     default IP address and port of LSCP server
1191    
1192 schoenebeck 579 Version 0.3.1 (24 May 2005)
1193    
1194     * initial release
