Abstract
An electronic gaming (e.g., video game) device includes a pseudo-stereo sound generator. Plural independent sound generating circuits produce audio signals under microcomputer control. The microcomputer may route the outputs of the plural sound generating circuits independently to one or the other (or both) of two independent audio channel outputs so as to produce pseudo-stereo sound. A selecting circuit automatically mixes the two audio channel outputs together and provides them in monaural form to an internal loudspeaker when no stereophonic headset is connected. A microcomputer controls generation of sounds and music in accordance with a musical pitch (frequency) data structure, a musical duration data structure and a musical score data structure stored in an interchangeable memory cartridge. The musical score data structure specifies pitch and duration in terms of address offsets into pitch and duration data structures.
