Abstract

Most of the circuitry of an electronic organ is made up of a plurality of digital large scale integrated (LSI) circuit chips. Certain of the chips can be duplicated or substituted for others of like type to provide an organ with more or less tone generators, more or less features, etc., whereby organs of various price levels can be constructed from the same basic parts. In operation, essentially all of the organ functions and features are provided by carrying out logical and arithmetic operations on digital pulse trains generated under control of a master clock.
