2 summary:: score of timed OSC commands
3 related:: Guides/Non-Realtime-Synthesis
4 categories:: Control, Server>NRT, External Control>OSC
7 Score encapsulates a list of timed OSC commands and provides some methods for using it, as well as support for the creation of binary OSC files for non-realtime synthesis. See link::Guides/Non-Realtime-Synthesis:: for more details.
9 The list should be in the following format, with times in ascending order. Bundles are okay.
14 [beat2, [OSCcmd2], [OSCcmd3]],
17 [beatToEndNRT, [\c_set, 0, 0]] // finish
21 For NRT synthesis the final event should a dummy event, after which synthesis will cease. It is thus important that this event be timed to allow previous events to complete.
23 Score scheduling defaults to link::Classes/TempoClock::. A setting of code::TempoClock.default.tempo = 1 :: (60 beats per minute), may be used to express score events in seconds if desired.
30 returns a new Score object with the supplied list.
33 can be an link::Classes/Array::, a link::Classes/List::, or similar object.
36 as link::#*new::, but reads the list in from a text file.
39 a link::Classes/String:: indicating the path of the file. The file must contain a valid SC expression.
42 as link::#*new:: but immediately plays it. (See also the instance method below.)
48 If no value is supplied it will play on the default link::Classes/Server::.
51 as link::#*play::, but reads the list from a file.
54 a convenience method to create a binary OSC file for NRT synthesis. Does not create an instance.
60 a link::Classes/String:: containing the desired path of the OSC file.
63 Use clock as a tempo base. code::TempoClock.default:: is used if clock is nil.
66 as link::#*write:: but reads the list from a file.
69 a path to a file with a list.
72 a link::Classes/String:: containing the desired path of the OSC file.
75 Use clock as a tempo base. code::TempoClock.default:: is used if clock is nil.
78 a convenience method to synthesize strong::list:: in non-realtime. This method writes an OSC file to strong::oscFilePath:: (you have to do your own cleanup if desired) and then starts a server app to synthesize it. For details on valid headerFormats and sampleFormats see link::Classes/SoundFile::. Use code::TempoClock.default:: as a tempo base. Does not return an instance.
84 the path to which the binary OSC file will be written.
86 argument::outputFilePath
87 the path of the resultant soundfile.
89 argument::inputFilePath
90 an optional path for an input soundfile.
93 the sample rate at which synthesis will occur.
95 argument::headerFormat
96 the header format of the output file. The default is 'AIFF'.
98 argument::sampleFormat
99 the sample format of the output file. The default is 'int16'.
102 an instance of link::Classes/ServerOptions::. If not supplied the options of the default link::Classes/Server:: will be used.
104 argument::completionString
109 A function to be evaluated once the NRT server has finished rendering its score.
114 play the list on strong::server::, use strong::clock:: as a tempo base and quantize start time to strong::quant::. If strong::server:: is nil, then on the default server. code::TempoClock.default:: if strong::clock:: is nil. now if strong::quant:: is 0.
120 create a binary OSC file for NRT synthesis from the list. Use strong::clock:: as a tempo base. code::TempoClock.default:: if strong::clock:: is nil.
126 adds bundle to the list.
129 sort the score time order. This is recommended to do strong::before recordNRT or write:: when you are not sure about the packet order.
132 synthesize the score in non-realtime. For details of the arguments see link::#*recordNRT:: above.
135 save the score list as a text file to strong::path::.
