PROBLEM TO BE SOLVED: To reproduce tone color variation of an acoustic piano due to shelf board collision sound.SOLUTION: A first key pushing operation made to any of a plurality of keys is detected, and a second key pushing operation made after the first key pushing operation is detected is detected. Then, a string striking sound at first timing defined based on the first detected key pushing operation is generated, and a shelf board collision sound corresponding to the second key pushing operation is generated at second timing defined based on the first key pushing operation. |
