Abstract: A digital tone generator includes a modulo adder, an increment number register, two latches and a master clock. The adder continuously adds one of a plurality of predefined increment numbers with the adder's previously generated sums to create further sums and a carry output corresponding to one of a plurality of predetermined output tone frequencies. The system characteristics and increment numbers are selected to correspond to the predetermined frequencies and generate exact tonal frequency signals. The system characteristics and increment numbers are defined using a formula which accounts for the least common multiple of the rational number representation of the predetermined frequencies. In the preferred embodiment, the digital tone generator is used to select and generate one of a plurality of time code tones.

Abstract: Apparatus and method for generating complex sounds having a more natural and agreeable quality wherein fundamental and higher order components may be uniquely and independently controlled to inexact integer relationships.

Abstract: A musical note oscillator producing notes at musical intervals having high resolution and high frequency stability achieved with an economy of components and control signals. The oscillator may be operated to provide multiple notes simultaneously and independently; and it is described in the context of a musical instrument.
