PURPOSE:To suppress the generation of a sound which hurts ears and compose a musical sound of excellent sound quality by providing a 3rd scatter junction which puts respective string vibration signals into one between the scatter junctions of plural 1st waveguides which simulate plural strings and a 2nd waveguide which simulates a resonance body such as a sound board. CONSTITUTION:A sine wave signal of a half cycle outputted from an initial signal generating means 100 is inputted to the 1st waveguides of three systems through the 1st scatter junctions 110, 310, and 510 of the three systems which simulate the three strings. The signals of the three systems reaches the 3rd scatter junction 700 through the 2nd scatter junctions 180, 380, and 580 which simulate a bridge and part of it is reflected here and returned to the 1st waveguides. The rest is inputted to the 2nd waveguide 800 which simulates the resonance body. Thus, an acoustic musical instrument is simulated more precisely. |
