Octave Divider

A sound generation technique used in many electronic organs and string machines involves twelve oscillators which generate each note in the highest octave of the instrument. The signal (usually a square wave) from each oscillator is then passed to circuitry which acts as a mathematical divider, producing an output which sounds an octave lower, and this process is repeated for as many octaves the instrument is required to play. In this way all notes are available all the time, and the tuning between octaves is completely locked and stable.
