<P>PROBLEM TO BE SOLVED: To provide technical means for improving playing feeling that a player playing an electronic keyboard musical instrument senses with the tactile sense of the body. <P>SOLUTION: A drive control part 52 separates a sum signal Y of musical sound signals Y<SB POS="POST">L</SB>' and Y<SB POS="POST">R</SB>' that are generated by a sound production control part 51, into a transient signal Y<SB POS="POST">T</SB>including a transient component of the signal Y and a sustained signal Y<SB POS="POST">S</SB>containing a component other than the transient component. The transient signal Y<SB POS="POST">T</SB>is supplied to actuators 36-DP, 36-STP, and 36-SP. The sustained signal Y<SB POS="POST">S</SB>is supplied to an actuator 17. The actuators 36-DP, 36-STP, and 36-SP transmit vibration according to the signal Y<SB POS="POST">T</SB>to the foot of the player. The actuator 17 transmits vibration according to the signal Y<SB POS="POST">S</SB>to the hand fingers of the player. <P>COPYRIGHT: (C)2013,JPO&INPIT |
