Abstract
A digital synthesizer primarily intended for use in electronic musical instruments which are microprocessor controlled includes a plurality of storage devices which contain numerical data commensurate with the characteristics of an output signal to be produced. Information is read out of these storage devices under the control of command signals having a predetermined repetition frequency. The generation of the command signals is controlled in such a manner as to permit the generation of harmonically related frequencies.
