PROBLEM TO BE SOLVED: To provide a musical sound signal synthesis method, a program, and a musical sound signal synthesis device for generating quasi musical instrument sounds expressing property possessed by sounds generated from a musical instrument of three-dimensional structure having wires and a body in reality.SOLUTION: The musical sound signal synthesis device calculates vibration of the wires from force exerted on the wires of a piano and generates musical sound signals indicating waveform simulating sounds generated from the piano in response to vibration. The device includes a damper model calculation means for obtaining performance information corresponding to an amount of pushing of a key of the piano and an amount of treading of damper pedal of the piano, and time-varying numerical values corresponding to a viscosity coefficient used in calculating force exerted by a damper to the wires in response to the obtained performance information. |
