Abstract

PURPOSE: To form the musical tone resembling to natural tone by freely setting the degrees of non- harmony of each higher harmonic at the forming of the musical tone through higher harmonic synthesis.
CONSTITUTION: The frequency numbers and logarithmic frequency numbers corresponding to touched key pitches are read out from frequency number memories 2, 18. On the other hand, a counter 19 counts clocks and generates higher harmonic degree signals, then the logarithmic degrees and logarithmic harmonic numbers from degree number, non-harmonic number memories 20, 21 are added in an adder 26 to which the frequency numbers corresponding to the higher harmonic degrees are applied via adder 22 and logarithm-natural number converter 23. Hence, the sum of the numerical values corresponding to the frequencies for each higher harmonic degree and the non-harmonic numbers is applied from the adder 26 to an accumulator 29, and the basic waveform signal corresponding to the touched key pitches through a sine function memory 10 and the non-harmonic number signal being read out from a higher harmonic number prime memory 12 are multiplied by a higher harmonic amplitude multiplier 13, thence the musical tone signal synthesized of each higher harmonic of varying degrees of non-harmony is formed from a cumulator 14.
