PROBLEM TO BE SOLVED: To provide a keyboard device which more exactly simulates key depression operations of a piano with an action mechanism and the like in consideration of existence of retention sections of key depression.SOLUTION: Which of virtual hammer actual speed and virtual hammer provisional speed is faster is determined, and the faster speed is adopted (S300). Then, when the virtual hammer actual speed is adopted, travel corresponding to the virtual hammer actual speed is integrated (S400). On the other hand, when the virtual hammer provisional speed is adopted, travel corresponding to the virtual hammer provisional speed is integrated (S410). Any integrated value exceeds '4.7' (Yes in S500), drive control is performed to a sound source to perform a sound production operation corresponding to a key (S600). |
