ABSTRACT:
Each one of a plurality of harmonic components is multiplied with a first amplitude coefficient to form a plurality of harmonic components corresponding to a musical tone signal having a desired waveform. Each of the harmonic components is varied with time by a first envelope waveform signal in accordance with a second amplitude coefficient corresponding to each harmonic to form a harmonic component of a spectrum varying with time in a desired manner. By using a second envelope waveform signal, amplitudes of respective harmonic components are varied in a predetermined manner and then the harmonic components are synthesized to form a musical tone.
