The EXTRACT feature
This feature will extract a segment of a sorted numeric score file according to instructions taken from a control file. The control file contains an instrument list and two time points, from and to, in the form: instruments 1 2 from 1:27.5 to 2:2
The component labels may be abbreviated as i, f and t. The time points denote the beginning and end of the extract in terms of: [section no.] : [beat no.].
each of the three parts is also optional. The default values for missing i, f or t are: all instruments, beginning of score, end of score.
extract reads an orchestra-readable score file and produces an orchestra-readable result. Comments, tabs and extra spaces are flushed, w and
a statements are added and an f0 reflecting the extract length is appended to the output. Following an extract process, the abbreviated score will contain all function table statements, together with just those note statements that occur in the from-to interval specified. Notes lying completely in the interval will be unmodified; notes that lie only partly within will have their p3 durations truncated as necessary.
