ABSTRACT:
A predetermined frequency signal is amplitude modulated with a time window signal having a predetermined time width to simultaneously calculate a plurality of frequency components distributed over a predetermined frequency bandwidth and having the frequency component as a center component, and the plurality of frequency components thus calculated are used as partial tone components to form a musical tone signal. The frequency signal and the time window signal are formed by using a common function signal generator, on a time division basis, which produces the frequency signal and the time window signal. This construction makes it possible to form a musical tone having a great number of harmonic components at high speeds with a simple circuit construction.
