  • Patent number: 4485717
    Abstract: An electronic musical instrument which produces a musical sound by controlling harmonics coefficient and using computing means based on the discrete Fourier transfer. For a fundamental wave, a period function indicated by predetermined period data is generated and, for a harmonic wave, a period function of a period having a predetermined relation to the period of the fundamental wave is generated. By the period function thus obtained, a modulating waveshape memory is read out to obtain modulating data, which is multiplied by a harmonic coefficient.
