Pulse divider and subharmonic generator
CGS736 is a pulse divider with integer divisions between 2 and 8 and 16, 32 and 64. The divider is used to generate interrelated pulses for use in creating poly-rhythms, and unusual sequences. It can also be run at audio frequencies as a sub-oscillator/sub harmonic generator.
