PURPOSE:To reproduce the musical sound of a natural musical instrument which has plural exciting mechanisms of different structure faithfully by calculating an excitation signal by using parameters corresponding to a desire musical sound, inputting the excitation signal to a loop means, and placing the loop means in a resonant state. CONSTITUTION:A signal which is circulated in a loop circuit 510 is inputted to a loop circuit 520 through a multiplier M6 and also inputted to a loop circuit 530 through the multiplier M6, a signal is similarly inputted from a loop circuit 520 to loop circuits 510 and 530, and a signal is inputted from the loop circuit 530 to the loop circuits 510 and 520 to simulate the interference among three strings. Then the outputs of the loop circuits 510, 520, and 530 are passed through multipliers M11, M12, and M13 and added by an adder A5 to generate a musical sound signal and a filter 6 is given resonance effect to give the generated signal, then the musical sound is produced by a speaker 7. |
