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 of the argument is optional. The default values for missing i, f or t are:

all instruments, beginning of score, end of score.
