Wed Apr 20 15:22:58 2016 UTC (3 years, 7 months ago) by schoenebeck
File size: 63375 byte(s)
* Automake: set environment variable GCC_COLORS=auto to allow GCC to
  auto detect whether it (sh/c)ould output its messages in color.
* Fixed behavior of built-in script function "ignore_event()".
* Bumped version (2.0.0.svn4).

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 2871
47 schoenebeck 2787 Version 2.0.0 (15 July 2015)

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

163 persson 2382 - bugfix: pitch LFO controller "internal+aftertouch" was broken
164     - bugfix: filter keyboard tracking was broken
165     - filter performance fix (an unnecessary copy was made of the
166     filter parameters in each sub fragment)
167     - handle special case when pan parameter in gig file has max or
168     min value
169 schoenebeck 2396 - Exclusive Groups: don't ever stop voices of the same note,
170     doesn't sound naturally with a drumkit

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

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