File size: 64465 byte(s)
* Implemented built-in instrument script function "change_vol()".
* Implemented built-in instrument script function "change_tune()".
* Implemented built-in instrument script function "change_pan()".
* Bumped version (2.0.0.svn11).

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 2931 - Implemented built-in script function "change_vol()".
63     - Implemented built-in script function "change_tune()".
64     - Implemented built-in script function "change_pan()".

102 persson 2519 - enabled automake 'subdir-objects' option and moved external
103     source references (vst, au, asio) from makefiles to cpp files,
104     in order to get rid of warnings from automake 1.14
105 persson 2382
106 persson 2086 * general changes:
107 iliev 2012 - Refactoring: moved the independent code from
108     the Gigasampler format engine to base classes
109 schoenebeck 2047 - command line option '--profile' is currently disabled, since the
110     respective profiling code is currently broken
111 schoenebeck 2053 - Introduced support for optional environment variable
112     "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
113     where the sampler shall look for instrument editor plugins
114     (patch by Luis Garrido, slightly modified).
115 schoenebeck 2121 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
116     - implemented Roland GS NRPN 1CrrH which allows to set pan per note
117     - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
118     note (in this implementation of the sampler its simply hard routed to
119     the 1st effect send of the sampler channel, no matter what the actual
120     effect type is)
121     - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
122     note (in this implementation of the sampler its simply hard routed to
123     the 2nd effect send of the sampler channel, no matter what the actual
124     effect type is)
125 schoenebeck 2124 - implemented support for internal LADSPA effects
126 schoenebeck 2140 - raised limit of program change queue from 100 to 512
127     (as suggested by Alex Stone)
128 iliev 2223 - implemented sine LFO, pulse LFO and saw LFO
129 iliev 2296 - experimental support for per voice equalization
130 iliev 2306 - added command line option --exec-after-init
131 schoenebeck 2330 - Introduced new C++ API method:
132     EngineChannel::InstrumentFileName(int index)
133     allowing to retrieve the whole list of files used for the loaded
134     instrument on an engine channel (a.k.a. part). Some GigaStudio
135     instruments for example are splitted over several files like
136     "Foo.gig", "Foo.gx01", "Foo.gx02", ...
137 schoenebeck 2375 - Added new C++ API method Sampler::GetGlobalMaxVoices().
138     - Added new C++ API method Sampler::GetGlobalMaxStreams().
139     - Added new C++ API method Sampler::SetGlobalMaxVoices().
140     - Added new C++ API method Sampler::SetGlobalMaxStreams().
141 schoenebeck 2377 - Various "const" and "restrict" optimizations.
142 persson 2382 - all engines: add pan CC value to instrument pan parameter before
143     applying panning, instead of using two separate pan functions in
144     series (#182)
145 persson 2427 - added a lock guard class for exception safe mutex handling and
146     used it everywhere appropriate
147 schoenebeck 2448 - Immediately apply scale tuning changes to active voices.
148     - Exposed scale tuning to C++ API (along to the already existing standard
149     SysEx way).
150 persson 2452 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
151     and broken for ppc64. (Seq_cst loads and stores are actually not
152     used in LS, so the bug wasn't noticable.)
153     - lsatomic.h: added ARMv7 support
154 schoenebeck 2500 - Added support for multiple MIDI input ports per sampler channel (and
155     added various new C++ methods for this new feature / design change, old
156     C++ API methods for managing SamplerChannel's MIDI inputs are now marked
157     as deprecated but are still there and should provide full behavior
158     backward compatibility).
159     - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
160     unsafe and caused compilation error with clang 2.x).
161 schoenebeck 2506 - Bugfix: only process the latest MIDI program change event.
162 schoenebeck 2515 - Introducing the LSCP shell, which provides convenient control of the
163     sampler from the command line by providing LSCP aware features.
164 schoenebeck 2521 - VirtualMidiDevice: Added support for program change.
165     - VirtualMidiDevice: Added support for bank select (MSB & LSB).
166     - VirtualMidiDevice: Added support for pitch bend.
167 schoenebeck 2559 - Aftertouch: extended API to explicitly handle channel pressure and
168     polyphonic key pressure events (so far polyphonic pressure was not
169     supported at all, and channel pressure was rerouted as CC128 but not
170     used so far).
171 schoenebeck 2594 - Added initial support for real-time instrument scripts. The script VM
172     code is shared by all sampler engine implemementations, however only the
173     gig file format currently provides support for storing instrument scripts
174     (as LinuxSampler extension to the original GigaStudio 4 format).
175 iliev 2012
176 persson 2043 * Gigasampler format engine:
177     - implemented the "round robin keyboard" dimension
178     - fixed round robin and random dimensions for cases when number of

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

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

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

696     stored in the plugin state
697 schoenebeck 1930 - performance optimization of AudioChannel::MixTo() and
698     AudioChannel::CopyTo() methods using GCC vector exensions
699     (if available)
700 persson 1951 - ASIO fixes: avoid initializing the device twice, avoid throwing
701     exception when getting parameters from a disconnected device
702 schoenebeck 1599
703 persson 1651 * MIDI driver:
704     - added JACK MIDI driver
705 schoenebeck 1715 - dispatch bank select as ordinary CC as well, the user might seriously
706     want to (mis)use it for some purpose ("fixed" in all current MIDI
707     input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
708 persson 1889 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
709 persson 1887 CoreMidi or AU
710 persson 1889 - fixed mingw-w64 compilation error in MME driver
711 persson 1924 - made program change handling in MIDI thread real-time safe by
712     moving the logic to a non-RT thread
713 persson 1951 - fixed minor memory leak in ALSA driver
714 persson 1651
715 schoenebeck 1604 * instruments database:
716 iliev 1603 - avoid time consuming samples scanning when adding instruments
717     to the instruments database
718 iliev 1727 - added support for handling lost files in the instruments database
719 iliev 1781 - Implemented option for adding instruments in separate directories
720     in the instruments database
721     (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
722 persson 1908 - work-around for missing fnmatch function on Windows to make
723     instrument database compilable
724 schoenebeck 1930 - added instrument database support on Windows
725     works with both standalone mode and VST plugin.
726     the instruments DB file is located in
727     %USERPROFILE%\.linuxsampler\instruments.db which allows different
728     databases for each windows user
729     if no DB is present it automatically creates the .linuxsampler subdir
730     and then creates an empty DB
731 persson 1943 - fixed recursive import, which was broken on Windows
732 iliev 1603
733 persson 1644 * Gigasampler format engine:
734     - fixed a memory leak that could happen when a channel was deleted
735     while notes were playing
736 persson 1646 - made it possible to load an instrument even if the audio thread
737     isn't running
738 persson 1701 - added partial support for the "Controller Triggered" MIDI rule,
739     enough for piano gigs with pedal noise samples
740 schoenebeck 1715 - minor fix: only mark FX sends as being modified if really the
741     respective FX send MIDI controller was used
742 schoenebeck 1724 - added support for GM global device volume SysEx message
743 schoenebeck 1762 (can be selected at compile time to either apply globally to the
744     whole sampler [default] or only to the sampler channels that are
745     connected to the respective MIDI input port the SysEx message arrived
746     on)
747 persson 1748 - bugfix: notes triggered at position 0 in the audio buffer were
748     sometimes wrongly killed in the same buffer, causing no sound to
749     be played
750 schoenebeck 1750 - added support for chromatic / drumkit mode Roland GS Sysex message
751     which is usally used to switch a part between chromatic sounds and
752     drumkit sounds (as opposed to their common default setting of MIDI
753     part 10 being a drumkit part and all other ones chromatic parts), in
754     LS however one can switch between the first 16 MIDI instrument maps
755     defined for the sampler
756 persson 1764 - made it possible to create multiple sample channels even if the
757     audio thread isn't running
758 persson 1844 - fixed crash when removing channel with active voices (#116)
759 schoenebeck 1852 - bugfix: on sample reference changes (instrument editor), only
760     un-cache the respective sample if it's really not used by any
761     sampler engine anymore
762     - re-cache samples in case they were changed by an instrument editor,
763     e.g. when a sample was added while playing (#82)
764 schoenebeck 1857 - fixed hanging notes which occured when note-off event had the exact
765     same time stamp as the voice's note-on event and occured both in the
766     same audio fragment cycle (fixes bug #112)
767 persson 1858 - added support for the "fine tune" and "pitch bend range"
768     instrument-level gig parameters
769     - fixed minor artifacts in pitch bend handling
770 schoenebeck 1860 - added support for GS Reset SysEx message
771 persson 1862 - allow gig files to use unlimited downward pitch shifting
772     - added a limit check for upward pitch shifting
773 persson 1906 - bugfix: sometimes, when playing a note twice fast, the second
774     note was silent
775 persson 1923 - fixed crash happening when a pitch bend event arrived at the
776     same time a new instrument was loading
777 persson 1644
778 schoenebeck 1687 * LSCP server:
779     - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
780     react on MIDI data arriving on certain sampler channels (so far only
781     Note-On and Note-Off events are sent via this LSCP event)
782 schoenebeck 1695 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
783     react on MIDI data arriving on certain MIDI input devices (so far only
784     Note-On and Note-Off events are sent via this LSCP event)
785 iliev 1727 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
786     SET DB_INSTRUMENT FILE_PATH
787 iliev 1771 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
788     frontends to send MIDI messages to specific sampler channel
789     - added two additional fields to GET FILE INSTRUMENT INFO command -
790     KEY_BINDINGS and KEYSWITCH_BINDINGS
791 iliev 1754 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
792     was incorrect
793 iliev 1763 - Optimized the retrieval of the MIDI instrument mappings
794 schoenebeck 1800 - added new LSCP command "SET VOICES" to globally alter the maximum
795     amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
796     be triggered respectively
797     - added new LSCP command "SET STREAMS" to globally alter the maximum
798     amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
799     which will be triggered respectively
800 persson 1808 - bugfix: retry if "select" returns EINTR (this fixes a crash when
801     a gigedit file dialog is opened)
802 iliev 1848 - close all connections when LSCPServer is deleted
803 iliev 1882 - hard close of all sockets on exit
804 persson 1897 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
805     driver
806 schoenebeck 1687
807 iliev 1761 * Bug fixes:
808     - fixed a crash which occurs when removing a sampler channel waiting
809     to start instrument loading after another channel
810 iliev 1826 - fixed a crash which occurs when removing a sampler channel with
811     instrument loading in progress (bug #113)
812 iliev 1827 - fixed termination caused by uncaught exception when adding MIDI
813     instrument with PERSISTENT load mode
814 iliev 1835 - fixed possible iterator invalidations when resetting the sampler
815     - fixed memory leaks when issuing the following LSCP commands:
816     GET AUDIO_OUTPUT_DRIVER INFO
817     GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
818     GET MIDI_INPUT_DRIVER INFO
819     GET MIDI_INPUT_DRIVER_PARAMETER INFO
820     - fixed possible compilation error when sqlite is not present
821 iliev 1843 - fixed orphaned pointers when setting maximum voices limit (bug #118)
822 iliev 1847 - fixed crash when changing the audio output device of a sampler
823     channel with loaded instrument and start playing notes
824 iliev 1855 - fixed endless loop in Engine::SuspendAll() (bug #120)
825 persson 1870 - fixed a low-level atomic load function that was broken on 64-bit
826     PowerPC, which probably could cause crashes on that platform
827 persson 1889 - fixed a memory management error which could cause a crash when a
828     plugin was unloaded
829 persson 1896 - bugfix: two private structs had the same name, which could cause
830     problems if the linker chose the wrong constructor
831 persson 1933 - fixed low-level ConditionServer usage bug that caused lockups on
832     Windows
833 iliev 1761
834    
835 schoenebeck 1560 Version 0.5.1 (6 December 2007)
836 schoenebeck 1454
837     * packaging changes:
838     - added autoconf checks for pthread library
839     - added autoconf check for pthread bug found on certain NPTL-enabled
840     glibc versions (see Gentoo bug report #194076)
841 senoner 1502 - added autoconf checks for MS Windows
842 schoenebeck 1454
843 persson 1455 * general changes:
844     - bugfix: the thread used by an editor plugin didn't die when the
845     editor closed
846 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
847     out all the space. operator--() did not apply size_mask after
848     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
849     order to avoid problems with the _NonVolatileReader functions.
850     - bugfix: Stream.h: added a missing divide by BytesPerSample in
851     GetWriteSpace(). Since this function is currently only used in
852     the stream's qsort() compare function, it didn't trigger any
853     bugs.
854     - Resampler.h, Synthesizer.h: cubic interpolation now works in
855     24bit mode too. Faster method to read 24bit words on little
856     endian machines (x86): replaced 3 byte reads + shifts with a 1
857     unaligned 32bit read and shift
858     - experimental support for MS Windows (MIDI input via MME, AUDIO
859     output via ASIO)
860     - made handling of SIGINT signal (Ctrl-C) a bit more robust
861 iliev 1541 - support for monitoring the total number of active disk streams
862     (new LSCP commands: GET TOTAL_STREAM_COUNT,
863     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
864 persson 1455
865 senoner 1500 * AUDIO driver:
866 persson 1534 - added Windows ASIO low latency audio driver
867 senoner 1500
868 senoner 1485 * MIDI driver:
869 schoenebeck 1495 - added MME Windows MIDI driver
870 senoner 1485
871 schoenebeck 1471 * LSCP server:
872     - added support for Windows style path / filenames, however with
873     forward slash path separators instead of backslash
874     (i.e. "C:/foo/bar.gig")
875 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
876     apostrophes as well
877 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
878     "LIST FILE INSTRUMENTS <file>" and
879     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
880     about an arbitrary instrument file on the system where the sampler is
881     running on
882 schoenebeck 1471
883 schoenebeck 1424 Version 0.5.0 (15 October 2007)
884 schoenebeck 947
885 schoenebeck 1065 * packaging changes:
886 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
887     API header files anymore
888 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
889     the Doxygen API documentation (explicitly listed in Doxyfile.in)
890 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
891     capable to execute our autoconf environment, thus no need anymore
892     to maintain the compile time configuration file (osx/version.h) for
893     OSX manually (patch by Toshi Nagata)
894 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
895     parameters
896 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
897     C++ API header files, all implementation internal global definitions
898     are now in global_private.h
899     - atomic.h is not exposed to the C++ API anymore
900     - no need to include config.h anymore for using LS's API header files
901     - fixed warnings in API doc generation
902 schoenebeck 1065
903 schoenebeck 947 * general changes:
904     - replaced the old, confusing MIDI program change mechanism by a
905     flexible MIDI instrument mapper which allows to map arbitrary
906 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
907 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
908     loaded on the respective channel when such MIDI program change
909     messages arrive, beside that, each entry allows to define a life-time
910     strategy for the instrument, so the user can define whether the
911     instrument should i.e. be permanently loaded (to be able to switch
912     quickly among sounds) or i.e. loaded just on demand when the
913     respective program change arrives (to safe RAM space), as well as a
914     global volume factor for each entry, so the user can adjust the volume
915     dynamic of his mapped instrument collection without having to modify
916 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
917     MIDI instrument maps and assign each sampler channel individually
918     a certain map, so that i.e. separation of normal instruments and
919     drumkits is possible
920 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
921     MIDI instrument maps, MIDI instruments, FX sends, global volume.
922 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
923     due to a constant size RingBuffer FIFO which is now replaced by a
924     dynamic (unlimited) size std::list FIFO
925 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
926     output channels for being processed by external effect processors
927     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
928     controllers
929 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
930 iliev 1130 - Implemented new, improved notification system
931 schoenebeck 1149 - fixed compilation errors regarding OSX
932     (patch by Toshi Nagata)
933 iliev 1161 - implemented instruments database
934 iliev 1345 - added support for escape sequences to the instruments database
935 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
936     within the sampler's process (by using instrument editor plugins),
937     you'll notice the new "Registered instrument editors:" message on
938 schoenebeck 1407 startup, added a new LSCP command:
939     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
940 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
941     given sampler channel, the plugin path can be overridden at compile
942     time with ./configure --enable-plugin-dir=/some/dir
943 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
944     in the sampler's process to safely edit instruments while playing
945     without a crash (hopefully) by either suspending single regions
946     wherever possible or if unavoidable whole engine(s)
947 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
948     policy and priority on thread level, set a minimum stack size for
949     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
950     threads simply inherited properties of starting thread instead of
951     setting their own policy and priority
952 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
953     main process did not wait for the stack trace process to finish
954     its output
955 persson 1248 - fixed some minor memory leaks
956 schoenebeck 1259 - reenabled assembly features support, at the moment only for
957     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
958 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
959     register, to avoid relocations in the text segment at runtime)
960 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
961 schoenebeck 947
962     * MIDI driver:
963     - dispatch bank select (MSB and LSB) messages
964    
965 schoenebeck 1049 * audio driver:
966     - the ALSA audio output driver parameters now reflect the correct
967     parameter value ranges for the respective selected sound card
968     (patch by Till Wimmer, a bit fixed and extended)
969    
970 persson 951 * Gigasampler format engine:
971     - if a filter is used and EG2 finishes before EG1, let the voice
972     die when EG2 has finished (this fixes a problem with clicks and
973     voice starvation for some gigs)
974 persson 1038 - playback is no longer disabled during instrument loading
975     - all notes playing on a channel that changes its instrument keep
976     playing with the old instrument until they get a note off
977     command
978 persson 1039 - EG fix: a release value of zero could cause noises or crash
979 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
980 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
981     above max sustain level, which means that there is a decay phase
982     even if sustain is 100%
983 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
984     noises or crashes
985 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
986 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
987     supplied to the configure script (fixes #46)
988 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
989     instead of a fix value
990 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
991     127 (solo mode) only kill voices if the respective mode really
992     changed
993 persson 951
994 schoenebeck 1244 * LSCP server:
995     - fixed compile time error for old Bison versions
996     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
997 schoenebeck 1245 - parser now supports extended ASCII character set
998     (up to ASCII code 255, i.e. includes now umlauts and accents)
999     - filename arguments in LSCP commands now allow to use escape
1000     sequences, that is directly literal as one of: \', \", \\, \n, \r,
1001     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1002     code value like \xf2) (fixes bug #24)
1003 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
1004     least one of their text-based parameters (i.e. name, description):
1005     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1006     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1007     "SET DB_INSTRUMENT_DIRECTORY NAME",
1008     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1009     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1010     "FIND DB_INSTRUMENT_DIRECTORIES"
1011 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
1012     occured, the unexpected character and the actually expected, possible
1013     character(s), the latter only if less than 5 possibilities)
1014 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
1015     settings
1016 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
1017     of strings were treated as being one string containing commas
1018     (fixes #57)
1019 schoenebeck 1244
1020 iliev 959 * Bug fixes:
1021     - fixed crash occurring on certain LSCP scripts (Bug 39)
1022 persson 1038 - another thread safety fix for lscp "load engine" and "set
1023     channel audio output device"
1024 iliev 1283 - fixed a crash which occurs when reassigning the same engine
1025     on a sampler channel with connected MIDI device
1026 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
1027     device connected to a sampler channel to number less then or equal
1028     to the index of the port to which the sampler channel is connected.
1029 iliev 1296 - The previous bindings were not been disconnected when altering
1030     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1031     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1032 iliev 1297 - The active stream/voice count statistic was incorrect.
1033 iliev 1298 - notification events were not been sent for some sampler
1034     channel changes
1035 iliev 1305 - added default min and max values to restrict the number of allowed
1036     audio output channels and MIDI input ports
1037 iliev 1306 - the connection to the PCM interface is now closed when destroying
1038     an audio output device
1039 schoenebeck 1332 - files with slash in their path or filename could not be loaded
1040 iliev 959
1041 schoenebeck 1221 * test cases:
1042     - updated and fixed (haven't been touched in a while)
1043    
1044 schoenebeck 937 Version 0.4.0 (24 November 2006)
1045 persson 696
1046 schoenebeck 697 * packaging changes:
1047 capela 868 - changed deprecated copyright attribute to license; added ldconfig
1048     to post-(un)install steps; added devel package for liblinuxsampler;
1049     to linuxsampler.spec (RPM)
1050 schoenebeck 697 - install necessary development header files for allowing 3rd party
1051     applications to link against liblinuxsampler
1052     - liblinuxsampler's API documentation can be generated with 'make docs'
1053     (Doxygen required)
1054 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
1055     implementation (currently either an integer math solution or a
1056     di-harmonic approximation), automatic detection can be overriden
1057     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1058     configure script argument though (mandatory for cross-compilation)
1059 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
1060     provided some on his own (as CXXFLAGS)
1061 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
1062     messages
1063 schoenebeck 852 - added compile time options to allow disabling the various audio and
1064     MIDI drivers
1065 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
1066     (patch by Ebrahim Mayat)
1067 schoenebeck 697
1068 persson 696 * Gigasampler format engine:
1069 schoenebeck 738 - extensive synthesis optimization
1070     (reimplementation of EGs and LFO(s), removed synthesis parameter
1071     prerendering and the synthesis parameter matrix in general, splitting
1072     each audio fragment into subfragments now where each subfragment uses
1073 persson 830 constant pitch and filter coefficients. The volume coefficient is
1074     linearly interpolated inside a subfragment, unless
1075     --disable-interpolate-volume is set.)
1076 persson 696 - fine tuning of the EG modulation parameters
1077 persson 729 - improved filter cutoff calculation by adding support for the
1078     following gig parameters: Cutoff freq (used when no cutoff
1079     controller is defined), Control invert, Minimum cutoff, Velocity
1080 persson 791 curve and Velocity range. The keyboard tracking now scales
1081     cutoff frequency instead of resonance.
1082 persson 877 - added support for gig parameter Resonance.
1083 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
1084 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1085     which can be overridden with --enable-global-attenuation
1086 persson 783 - EG fixes: made the length of "attack hold" stage more
1087     accurate. Release stage can now start before attack stage
1088 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
1089     time now has a minimal value to prevent clicks.
1090 persson 799 - fixed pitch changes larger than one octave
1091 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1092     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1093     all modes can be altered via standard GM messages, that is CC5 for
1094     altering portamento time, CC65 for enabling / disabling portamento
1095     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1096 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1097     parameter) and crossfade
1098 persson 831 - added support for the "attenuation controller threshold" gig
1099     parameter
1100 persson 832 - added smoothing of volume changes caused by control change
1101     messages
1102 persson 865 - sample loop parameters are now taken from the DimensionRegion
1103     instead of the wave chunk
1104     - fixed keyswitching for v3 gigs with a number of keyswitch splits
1105     not equal to a power of two
1106 persson 877 - reimplementation of the filter algorithm. The new filter is more
1107     accurate and supports all gig filter types, including bandreject
1108     and lowpass turbo.
1109 persson 903 - real support for 24 bit samples - samples are not truncated to
1110     16 bits anymore
1111     - support for aftertouch (channel pressure, not polyphonic
1112     aftertouch)
1113 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
1114     amplifying from 0)
1115 persson 696
1116 schoenebeck 711 * LSCP server:
1117     - fixed application exit on broken pipe error (fixes bug #20)
1118 iliev 793 - fixed the notification messages delay due to lack of
1119     network activity (fixes bug #26)
1120 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
1121     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1122 schoenebeck 711
1123 schoenebeck 838 * audio driver:
1124     - added aRts audio output driver (by no means RT safe)
1125    
1126 schoenebeck 775 * MIDI driver:
1127     - fixed legacy sysex code which caused dispatching of MIDI SysEx
1128     messages several times instead of once
1129 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
1130     for events (i.e. for offline rendering based MIDI drivers)
1131 persson 922 - added checks for bad MIDI data
1132 schoenebeck 775
1133 schoenebeck 900 * linuxsampler application:
1134     - show available sampler engine types on startup
1135    
1136 schoenebeck 705 * general changes:
1137     - support for muting sampler channels and solo mode of the same, two new
1138     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1139     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1140     introduced for this, the behavior is the same like on a mixer console
1141 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1142     --enable-process-muted-channels which can be used to enable the
1143     processing of muted channels.
1144 iliev 777 - support for sostenuto pedal
1145 iliev 779 - support for monitoring the total number of active voices
1146 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1147     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1148 persson 835 - fixed some memory management errors
1149 persson 841 - fixed some concurrency problems that could lead to crashes when
1150     LSCP commands were executed
1151 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
1152     sampler channel (fixes bug #36)
1153 schoenebeck 705
1154 schoenebeck 692 Version 0.3.3 (15 July 2005)
1155 schoenebeck 686
1156     * packaging changes:
1157     - fixed compilation with gcc 4.0
1158    
1159 schoenebeck 687 * Gigasampler format engine:
1160     - LFO preprocessing was performed even though the respective LFO was
1161     disabled by the instrument patch (minor efficiency fix)
1162 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1163     for volume ramp downs in the same fragment (needed for current voice
1164     stealing implementation) then simply inform the user with a warning
1165     about possible click sounds and reduce the volume ramp down
1166     appropriately instead of cancelling the audio device connection
1167 schoenebeck 687
1168 schoenebeck 677 Version 0.3.2 (24 June 2005)
1169 schoenebeck 609
1170     * packaging changes:
1171     - updated autotools build files to compile on OS X
1172     (conditional compilation of CoreMIDI and MidiShare drivers)
1173 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
1174     './configure --disable-asm' (definitely not recommended)
1175 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
1176     - require automake (>= 1.5) for 'make -f Makefile.cvs'
1177     (due to 'dist-bzip2' automake option)
1178 schoenebeck 649
1179     * Gigasampler format engine:
1180     - support for the gig parameters for "release velocity response" curves
1181     - fine tuning of the EGADSR envelope
1182     - volume of release triggered samples now depends on note-on velocity,
1183     note length and gig parameter "release trigger decay" instead of
1184     note-off velocity.
1185 schoenebeck 663 - revised voice stealing
1186     (fixes crash and endless loop caused by voice stealing)
1187 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
1188 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
1189     instead of when the respective voice is actually launched
1190     (fixes undefined behavior if stolen voices belonged to a key group -
1191     this case was followed by a "killed voice survived" error message)
1192 schoenebeck 669 - fixed minor issue with null/silence samples
1193     (those stole voices even though they don't need a voice at all which
1194     resulted in "voice stealing didn't work out" messages)
1195 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
1196     instrument or audio output device change
1197 schoenebeck 654
1198 schoenebeck 620 * LSCP server:
1199 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1200 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
1201 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
1202 schoenebeck 609
1203 schoenebeck 668 * linuxsampler application:
1204     - added command line parameters --lscp-addr and --lscp-port to override
1205     default IP address and port of LSCP server
1206    
1207 schoenebeck 579 Version 0.3.1 (24 May 2005)
1208    
1209     * initial release
