A sound interface circuit is implemented in large scale integrated circuitry (LSI) on a single chip to provide 3 voice electronic music synthesizer/sound effects, and is compatible with instructions from commercially available microprocessors; whereof a wide range, high-resolution control of pitch (frequency) tone color (harmonic content) and dynamics (volume) is achieved and specialized control circuitry minimizes software overhead, facilitating use in arcade/home video games and low cost musical instruments.
