<P>PROBLEM TO BE SOLVED: To provide a keyboard musical instrument capable of reducing a load of an actuator for driving a key in automatic musical performance, to save electric power, by reducing a load of generating inner force sense of the key in the automatic musical performance. <P>SOLUTION: The keyboard musical instrument has the actuator for driving the key 2 corresponding to articulation, in the automatic musical performance. A CPU controls only a load in a mechanical load mechanism 3 to get as low as possible, since a user does not operate the key 2 and since the inner force sense is not required to be applied, in the automatic musical performance. The load of the actuator for driving the key 2 in the automatic musical performance is reduced, and the electric power is saved, by this manner. <P>COPYRIGHT: (C)2010,JPO&INPIT |
