Delta Arcs

In the XJ music system, the main program is divided into sequences. Each segment is a musical composition that is based on a sequence.

The delta value of any segment counts from 0 (at the beginning of the main program) incrementing each segment by the total number of beats in that segment. The delta value is used to calculate the relative position of a segment in the main program.

The delta arc value of any segment is the intensity of the segment. The arc value is used to calculate the intensity of the segment in the main program.
