* Fix: Release trigger voices were not spawned on sustain pedal up
  (CC #64) events.
* Fix: Release trigger voices can now also distinguish correctly between
  note-off and sustain pedal up events.
* Bumped version (2.0.0.svn10).

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 schoenebeck 2927 - Fix: Release trigger voices were not spawned on sustain pedal up
24     (CC #64) events.
25     - Fix: Release trigger voices can now also distinguish correctly between
26     note-off and sustain pedal up events.
27 persson 2837
28 schoenebeck 2866 * packaging changes:
29     - removed unnecessary dependency to libuuid
30     (originated by libgig's usage of it)
31 schoenebeck 2884 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
32     auto detect whether it (sh/c)ould output its messages in color.
33 schoenebeck 2866
34 schoenebeck 2871 * Real-time instrument scripts:
35     - Implemented scheduler for delayed MIDI events and for suspended scripts.
36     - Built-in script function "wait()": implemented support for function's
37     "duration-us" argument, thus scripts using this function are now
38     correctly resumed after the requested amount of microseconds.
39     - Built-in script function "play_note()": implemented support for
40     function's "duration-us" argument, thus notes triggered with this
41     argument are now correctly released after the requested amount of
42     microseconds.
43     - Fix: script events were not cleared when engine channel was reset,
44     potentially causing undefined behavior.
45     - Fixed crash which happened when trying to reference an undeclared
46     variable.
47 schoenebeck 2879 - Built-in script function "play_note()": Added support for passing
48     special value -1 for "duration-us" argument, which will cause the
49     triggered note to be released once the original note was released.
50 schoenebeck 2885 - Instrument script classes now exported with the liblinuxsampler C++ API.
51     - Added new API method ScriptVM::syntaxHighlighting() which provides
52     a convenient syntax highlighting backend for external instrument
53     script editor applications.
54 schoenebeck 2889 - Added new C++ API class "ScriptVMFactory".
55     - Extended parser issues to provide not only first line and first
56     column, but also last line and last column of issue (thus marking
57     the precise span of the issue within the source code).
58 schoenebeck 2902 - Reload script automatically after being modified by an instrument
59     editor.
60 schoenebeck 2911 - NKSP language grammar correction: allow empty event handler bodies
61     like "on note end on".
62 schoenebeck 2871
63 schoenebeck 2787 Version 2.0.0 (15 July 2015)

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

182     filter parameters in each sub fragment)
183     - handle special case when pan parameter in gig file has max or
184     min value
185 schoenebeck 2396 - Exclusive Groups: don't ever stop voices of the same note,
186     doesn't sound naturally with a drumkit

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

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

698     exception when getting parameters from a disconnected device
699 schoenebeck 1599
700 persson 1651 * MIDI driver:
701     - added JACK MIDI driver
702 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
703     want to (mis)use it for some purpose ("fixed" in all current MIDI
704     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
705 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
706 persson 1887 CoreMidi or AU
707 persson 1889 - fixed mingw-w64 compilation error in MME driver
708 persson 1924 - made program change handling in MIDI thread real-time safe by
709     moving the logic to a non-RT thread
710 persson 1951 - fixed minor memory leak in ALSA driver
711 persson 1651
712 schoenebeck 1604 * instruments database:
713 iliev 1603 - avoid time consuming samples scanning when adding instruments
714     to the instruments database
715 iliev 1727 - added support for handling lost files in the instruments database
716 iliev 1781 - Implemented option for adding instruments in separate directories
717     in the instruments database
718     (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
719 persson 1908 - work-around for missing fnmatch function on Windows to make
720     instrument database compilable
721 schoenebeck 1930 - added instrument database support on Windows
722     works with both standalone mode and VST plugin.
723     the instruments DB file is located in
724     %USERPROFILE%\.linuxsampler\instruments.db which allows different
725     databases for each windows user
726     if no DB is present it automatically creates the .linuxsampler subdir
727     and then creates an empty DB
728 persson 1943 - fixed recursive import, which was broken on Windows
729 iliev 1603
730 persson 1644 * Gigasampler format engine:
731     - fixed a memory leak that could happen when a channel was deleted
732     while notes were playing
733 persson 1646 - made it possible to load an instrument even if the audio thread
734     isn't running
735 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
736     enough for piano gigs with pedal noise samples
737 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
738     respective FX send MIDI controller was used
739 schoenebeck 1724 - added support for GM global device volume SysEx message
740 schoenebeck 1762 (can be selected at compile time to either apply globally to the
741     whole sampler [default] or only to the sampler channels that are
742     connected to the respective MIDI input port the SysEx message arrived
743     on)
744 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
745     sometimes wrongly killed in the same buffer, causing no sound to
746     be played
747 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
748     which is usally used to switch a part between chromatic sounds and
749     drumkit sounds (as opposed to their common default setting of MIDI
750     part 10 being a drumkit part and all other ones chromatic parts), in
751     LS however one can switch between the first 16 MIDI instrument maps
752     defined for the sampler
753 persson 1764 - made it possible to create multiple sample channels even if the
754     audio thread isn't running
755 persson 1844 - fixed crash when removing channel with active voices (#116)
756 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
757     un-cache the respective sample if it's really not used by any
758     sampler engine anymore
759     - re-cache samples in case they were changed by an instrument editor,
760     e.g. when a sample was added while playing (#82)
761 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
762     same time stamp as the voice's note-on event and occured both in the
763     same audio fragment cycle (fixes bug #112)
764 persson 1858 - added support for the "fine tune" and "pitch bend range"
765     instrument-level gig parameters
766     - fixed minor artifacts in pitch bend handling
767 schoenebeck 1860 - added support for GS Reset SysEx message
768 persson 1862 - allow gig files to use unlimited downward pitch shifting
769     - added a limit check for upward pitch shifting
770 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
771     note was silent
772 persson 1923 - fixed crash happening when a pitch bend event arrived at the
773     same time a new instrument was loading
774 persson 1644
775 schoenebeck 1687 * LSCP server:
776     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
777     react on MIDI data arriving on certain sampler channels (so far only
778     Note-On and Note-Off events are sent via this LSCP event)
779 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
780     react on MIDI data arriving on certain MIDI input devices (so far only
781     Note-On and Note-Off events are sent via this LSCP event)
782 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
783     SET DB_INSTRUMENT FILE_PATH
784 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
785     frontends to send MIDI messages to specific sampler channel
786     - added two additional fields to GET FILE INSTRUMENT INFO command -
787     KEY_BINDINGS and KEYSWITCH_BINDINGS
788 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
789     was incorrect
790 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
791 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
792     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
793     be triggered respectively
794     - added new LSCP command "SET STREAMS" to globally alter the maximum
795     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
796     which will be triggered respectively
797 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
798     a gigedit file dialog is opened)
799 iliev 1848 - close all connections when LSCPServer is deleted
800 iliev 1882 - hard close of all sockets on exit
801 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
802     driver
803 schoenebeck 1687
804 iliev 1761 * Bug fixes:
805     - fixed a crash which occurs when removing a sampler channel waiting
806     to start instrument loading after another channel
807 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
808     instrument loading in progress (bug #113)
809 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
810     instrument with PERSISTENT load mode
811 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
812     - fixed memory leaks when issuing the following LSCP commands:
813     GET AUDIO_OUTPUT_DRIVER INFO
814     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
815     GET MIDI_INPUT_DRIVER INFO
816     GET MIDI_INPUT_DRIVER_PARAMETER INFO
817     - fixed possible compilation error when sqlite is not present
818 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
819 iliev 1847 - fixed crash when changing the audio output device of a sampler
820     channel with loaded instrument and start playing notes
821 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
822 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
823     PowerPC, which probably could cause crashes on that platform
824 persson 1889 - fixed a memory management error which could cause a crash when a
825     plugin was unloaded
826 persson 1896 - bugfix: two private structs had the same name, which could cause
827     problems if the linker chose the wrong constructor
828 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
829     Windows
830 iliev 1761
831    
832 schoenebeck 1560 Version 0.5.1 (6 December 2007)
833 schoenebeck 1454
834     * packaging changes:
835     - added autoconf checks for pthread library
836     - added autoconf check for pthread bug found on certain NPTL-enabled
837     glibc versions (see Gentoo bug report #194076)
838 senoner 1502 - added autoconf checks for MS Windows
839 schoenebeck 1454
840 persson 1455 * general changes:
841     - bugfix: the thread used by an editor plugin didn't die when the
842     editor closed
843 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
844     out all the space. operator--() did not apply size_mask after
845     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
846     order to avoid problems with the _NonVolatileReader functions.
847     - bugfix: Stream.h: added a missing divide by BytesPerSample in
848     GetWriteSpace(). Since this function is currently only used in
849     the stream's qsort() compare function, it didn't trigger any
850     bugs.
851     - Resampler.h, Synthesizer.h: cubic interpolation now works in
852     24bit mode too. Faster method to read 24bit words on little
853     endian machines (x86): replaced 3 byte reads + shifts with a 1
854     unaligned 32bit read and shift
855     - experimental support for MS Windows (MIDI input via MME, AUDIO
856     output via ASIO)
857     - made handling of SIGINT signal (Ctrl-C) a bit more robust
858 iliev 1541 - support for monitoring the total number of active disk streams
859     (new LSCP commands: GET TOTAL_STREAM_COUNT,
860     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
861 persson 1455
862 senoner 1500 * AUDIO driver:
863 persson 1534 - added Windows ASIO low latency audio driver
864 senoner 1500
865 senoner 1485 * MIDI driver:
866 schoenebeck 1495 - added MME Windows MIDI driver
867 senoner 1485
868 schoenebeck 1471 * LSCP server:
869     - added support for Windows style path / filenames, however with
870     forward slash path separators instead of backslash
871     (i.e. "C:/foo/bar.gig")
872 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
873     apostrophes as well
874 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
875     "LIST FILE INSTRUMENTS <file>" and
876     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
877     about an arbitrary instrument file on the system where the sampler is
878     running on
879 schoenebeck 1471
880 schoenebeck 1424 Version 0.5.0 (15 October 2007)
881 schoenebeck 947
882 schoenebeck 1065 * packaging changes:
883 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
884     API header files anymore
885 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
886     the Doxygen API documentation (explicitly listed in Doxyfile.in)
887 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
888     capable to execute our autoconf environment, thus no need anymore
889     to maintain the compile time configuration file (osx/version.h) for
890     OSX manually (patch by Toshi Nagata)
891 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
892     parameters
893 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
894     C++ API header files, all implementation internal global definitions
895     are now in global_private.h
896     - atomic.h is not exposed to the C++ API anymore
897     - no need to include config.h anymore for using LS's API header files
898     - fixed warnings in API doc generation
899 schoenebeck 1065
900 schoenebeck 947 * general changes:
901     - replaced the old, confusing MIDI program change mechanism by a
902     flexible MIDI instrument mapper which allows to map arbitrary
903 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
904 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
905     loaded on the respective channel when such MIDI program change
906     messages arrive, beside that, each entry allows to define a life-time
907     strategy for the instrument, so the user can define whether the
908     instrument should i.e. be permanently loaded (to be able to switch
909     quickly among sounds) or i.e. loaded just on demand when the
910     respective program change arrives (to safe RAM space), as well as a
911     global volume factor for each entry, so the user can adjust the volume
912     dynamic of his mapped instrument collection without having to modify
913 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
914     MIDI instrument maps and assign each sampler channel individually
915     a certain map, so that i.e. separation of normal instruments and
916     drumkits is possible
917 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
918     MIDI instrument maps, MIDI instruments, FX sends, global volume.
919 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
920     due to a constant size RingBuffer FIFO which is now replaced by a
921     dynamic (unlimited) size std::list FIFO
922 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
923     output channels for being processed by external effect processors
924     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
925     controllers
926 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
927 iliev 1130 - Implemented new, improved notification system
928 schoenebeck 1149 - fixed compilation errors regarding OSX
929     (patch by Toshi Nagata)
930 iliev 1161 - implemented instruments database
931 iliev 1345 - added support for escape sequences to the instruments database
932 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
933     within the sampler's process (by using instrument editor plugins),
934     you'll notice the new "Registered instrument editors:" message on
935 schoenebeck 1407 startup, added a new LSCP command:
936     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
937 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
938     given sampler channel, the plugin path can be overridden at compile
939     time with ./configure --enable-plugin-dir=/some/dir
940 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
941     in the sampler's process to safely edit instruments while playing
942     without a crash (hopefully) by either suspending single regions
943     wherever possible or if unavoidable whole engine(s)
944 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
945     policy and priority on thread level, set a minimum stack size for
946     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
947     threads simply inherited properties of starting thread instead of
948     setting their own policy and priority
949 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
950     main process did not wait for the stack trace process to finish
951     its output
952 persson 1248 - fixed some minor memory leaks
953 schoenebeck 1259 - reenabled assembly features support, at the moment only for
954     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
955 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
956     register, to avoid relocations in the text segment at runtime)
957 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
958 schoenebeck 947
959     * MIDI driver:
960     - dispatch bank select (MSB and LSB) messages
961    
962 schoenebeck 1049 * audio driver:
963     - the ALSA audio output driver parameters now reflect the correct
964     parameter value ranges for the respective selected sound card
965     (patch by Till Wimmer, a bit fixed and extended)
966    
967 persson 951 * Gigasampler format engine:
968     - if a filter is used and EG2 finishes before EG1, let the voice
969     die when EG2 has finished (this fixes a problem with clicks and
970     voice starvation for some gigs)
971 persson 1038 - playback is no longer disabled during instrument loading
972     - all notes playing on a channel that changes its instrument keep
973     playing with the old instrument until they get a note off
974     command
975 persson 1039 - EG fix: a release value of zero could cause noises or crash
976 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
977 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
978     above max sustain level, which means that there is a decay phase
979     even if sustain is 100%
980 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
981     noises or crashes
982 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
983 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
984     supplied to the configure script (fixes #46)
985 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
986     instead of a fix value
987 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
988     127 (solo mode) only kill voices if the respective mode really
989     changed
990 persson 951
991 schoenebeck 1244 * LSCP server:
992     - fixed compile time error for old Bison versions
993     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
994 schoenebeck 1245 - parser now supports extended ASCII character set
995     (up to ASCII code 255, i.e. includes now umlauts and accents)
996     - filename arguments in LSCP commands now allow to use escape
997     sequences, that is directly literal as one of: \', \", \\, \n, \r,
998     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
999     code value like \xf2) (fixes bug #24)
1000 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
1001     least one of their text-based parameters (i.e. name, description):
1002     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1003     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1004     "SET DB_INSTRUMENT_DIRECTORY NAME",
1005     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1006     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1007     "FIND DB_INSTRUMENT_DIRECTORIES"
1008 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
1009     occured, the unexpected character and the actually expected, possible
1010     character(s), the latter only if less than 5 possibilities)
1011 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
1012     settings
1013 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
1014     of strings were treated as being one string containing commas
1015     (fixes #57)
1016 schoenebeck 1244
1017 iliev 959 * Bug fixes:
1018     - fixed crash occurring on certain LSCP scripts (Bug 39)
1019 persson 1038 - another thread safety fix for lscp "load engine" and "set
1020     channel audio output device"
1021 iliev 1283 - fixed a crash which occurs when reassigning the same engine
1022     on a sampler channel with connected MIDI device
1023 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
1024     device connected to a sampler channel to number less then or equal
1025     to the index of the port to which the sampler channel is connected.
1026 iliev 1296 - The previous bindings were not been disconnected when altering
1027     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1028     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1029 iliev 1297 - The active stream/voice count statistic was incorrect.
1030 iliev 1298 - notification events were not been sent for some sampler
1031     channel changes
1032 iliev 1305 - added default min and max values to restrict the number of allowed
1033     audio output channels and MIDI input ports
1034 iliev 1306 - the connection to the PCM interface is now closed when destroying
1035     an audio output device
1036 schoenebeck 1332 - files with slash in their path or filename could not be loaded
1037 iliev 959
1038 schoenebeck 1221 * test cases:
1039     - updated and fixed (haven't been touched in a while)
1040    
1041 schoenebeck 937 Version 0.4.0 (24 November 2006)
1042 persson 696
1043 schoenebeck 697 * packaging changes:
1044 capela 868 - changed deprecated copyright attribute to license; added ldconfig
1045     to post-(un)install steps; added devel package for liblinuxsampler;
1046     to linuxsampler.spec (RPM)
1047 schoenebeck 697 - install necessary development header files for allowing 3rd party
1048     applications to link against liblinuxsampler
1049     - liblinuxsampler's API documentation can be generated with 'make docs'
1050     (Doxygen required)
1051 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
1052     implementation (currently either an integer math solution or a
1053     di-harmonic approximation), automatic detection can be overriden
1054     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1055     configure script argument though (mandatory for cross-compilation)
1056 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
1057     provided some on his own (as CXXFLAGS)
1058 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
1059     messages
1060 schoenebeck 852 - added compile time options to allow disabling the various audio and
1061     MIDI drivers
1062 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
1063     (patch by Ebrahim Mayat)
1064 schoenebeck 697
1065 persson 696 * Gigasampler format engine:
1066 schoenebeck 738 - extensive synthesis optimization
1067     (reimplementation of EGs and LFO(s), removed synthesis parameter
1068     prerendering and the synthesis parameter matrix in general, splitting
1069     each audio fragment into subfragments now where each subfragment uses
1070 persson 830 constant pitch and filter coefficients. The volume coefficient is
1071     linearly interpolated inside a subfragment, unless
1072     --disable-interpolate-volume is set.)
1073 persson 696 - fine tuning of the EG modulation parameters
1074 persson 729 - improved filter cutoff calculation by adding support for the
1075     following gig parameters: Cutoff freq (used when no cutoff
1076     controller is defined), Control invert, Minimum cutoff, Velocity
1077 persson 791 curve and Velocity range. The keyboard tracking now scales
1078     cutoff frequency instead of resonance.
1079 persson 877 - added support for gig parameter Resonance.
1080 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
1081 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1082     which can be overridden with --enable-global-attenuation
1083 persson 783 - EG fixes: made the length of "attack hold" stage more
1084     accurate. Release stage can now start before attack stage
1085 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
1086     time now has a minimal value to prevent clicks.
1087 persson 799 - fixed pitch changes larger than one octave
1088 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1089     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1090     all modes can be altered via standard GM messages, that is CC5 for
1091     altering portamento time, CC65 for enabling / disabling portamento
1092     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1093 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1094     parameter) and crossfade
1095 persson 831 - added support for the "attenuation controller threshold" gig
1096     parameter
1097 persson 832 - added smoothing of volume changes caused by control change
1098     messages
1099 persson 865 - sample loop parameters are now taken from the DimensionRegion
1100     instead of the wave chunk
1101     - fixed keyswitching for v3 gigs with a number of keyswitch splits
1102     not equal to a power of two
1103 persson 877 - reimplementation of the filter algorithm. The new filter is more
1104     accurate and supports all gig filter types, including bandreject
1105     and lowpass turbo.
1106 persson 903 - real support for 24 bit samples - samples are not truncated to
1107     16 bits anymore
1108     - support for aftertouch (channel pressure, not polyphonic
1109     aftertouch)
1110 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
1111     amplifying from 0)
1112 persson 696
1113 schoenebeck 711 * LSCP server:
1114     - fixed application exit on broken pipe error (fixes bug #20)
1115 iliev 793 - fixed the notification messages delay due to lack of
1116     network activity (fixes bug #26)
1117 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
1118     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1119 schoenebeck 711
1120 schoenebeck 838 * audio driver:
1121     - added aRts audio output driver (by no means RT safe)
1122    
1123 schoenebeck 775 * MIDI driver:
1124     - fixed legacy sysex code which caused dispatching of MIDI SysEx
1125     messages several times instead of once
1126 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
1127     for events (i.e. for offline rendering based MIDI drivers)
1128 persson 922 - added checks for bad MIDI data
1129 schoenebeck 775
1130 schoenebeck 900 * linuxsampler application:
1131     - show available sampler engine types on startup
1132    
1133 schoenebeck 705 * general changes:
1134     - support for muting sampler channels and solo mode of the same, two new
1135     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1136     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1137     introduced for this, the behavior is the same like on a mixer console
1138 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1139     --enable-process-muted-channels which can be used to enable the
1140     processing of muted channels.
1141 iliev 777 - support for sostenuto pedal
1142 iliev 779 - support for monitoring the total number of active voices
1143 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1144     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1145 persson 835 - fixed some memory management errors
1146 persson 841 - fixed some concurrency problems that could lead to crashes when
1147     LSCP commands were executed
1148 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
1149     sampler channel (fixes bug #36)
1150 schoenebeck 705
1151 schoenebeck 692 Version 0.3.3 (15 July 2005)
1152 schoenebeck 686
1153     * packaging changes:
1154     - fixed compilation with gcc 4.0
1155    
1156 schoenebeck 687 * Gigasampler format engine:
1157     - LFO preprocessing was performed even though the respective LFO was
1158     disabled by the instrument patch (minor efficiency fix)
1159 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1160     for volume ramp downs in the same fragment (needed for current voice
1161     stealing implementation) then simply inform the user with a warning
1162     about possible click sounds and reduce the volume ramp down
1163     appropriately instead of cancelling the audio device connection
1164 schoenebeck 687
1165 schoenebeck 677 Version 0.3.2 (24 June 2005)
1166 schoenebeck 609
1167     * packaging changes:
1168     - updated autotools build files to compile on OS X
1169     (conditional compilation of CoreMIDI and MidiShare drivers)
1170 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
1171     './configure --disable-asm' (definitely not recommended)
1172 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
1173     - require automake (>= 1.5) for 'make -f Makefile.cvs'
1174     (due to 'dist-bzip2' automake option)
1175 schoenebeck 649
1176     * Gigasampler format engine:
1177     - support for the gig parameters for "release velocity response" curves
1178     - fine tuning of the EGADSR envelope
1179     - volume of release triggered samples now depends on note-on velocity,
1180     note length and gig parameter "release trigger decay" instead of
1181     note-off velocity.
1182 schoenebeck 663 - revised voice stealing
1183     (fixes crash and endless loop caused by voice stealing)
1184 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
1185 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
1186     instead of when the respective voice is actually launched
1187     (fixes undefined behavior if stolen voices belonged to a key group -
1188     this case was followed by a "killed voice survived" error message)
1189 schoenebeck 669 - fixed minor issue with null/silence samples
1190     (those stole voices even though they don't need a voice at all which
1191     resulted in "voice stealing didn't work out" messages)
1192 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
1193     instrument or audio output device change
1194 schoenebeck 654
1195 schoenebeck 620 * LSCP server:
1196 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1197 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
1198 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
1199 schoenebeck 609
1200 schoenebeck 668 * linuxsampler application:
1201     - added command line parameters --lscp-addr and --lscp-port to override
1202     default IP address and port of LSCP server
1203    
1204 schoenebeck 579 Version 0.3.1 (24 May 2005)
1205    
1206     * initial release
