This is a subharmonic generator similar to my first one, except
that this one makes a perfect fifth instead of an octave. It is
made up of a digital divide by 3 circuit with symmetrical
square wave output.
This circuit produces a square wave tone that is one perfect fifth
above a tone 2 octaves below the VCO pitch. Example, play a C2 and this circuit
produces F1. This F1 is a tiny bit sharper than an equally tempered
fifth. The tone produce is not equally tempered, and therefore will
beat slowly with an equally tempered fifth. This will "fatten" the
Note: THIS IS UNDER DEVELOPMENT & CAN CHANGE.
