In a loop circuit having a low-pass filter, a delay circuit, and an all-pass filter, a wave signal read from a wave memory is supplied as an excitation signal to the loop circuit and circulated therein to synthesize a musical tone signal. A musical tone signal to be synthesized and processed by a signal processing system having a characteristic inverse to the loop circuit is stored in the wave memory.
