It tracks faithfully with a 1v/oct input up to 8 octaves, and contains a range switch with 5 notches that jump by octaves. The Pulse Width of the square wave can be modulated with CV or controlled manually for timbral manipulations. It also contains a hard sync input for locking it to the frequency of another oscillator.
