Actuator drive control control equipment and automatic performance device for automatic performance device

摘要

P To suitably control the drive of an actuator so that pedals and keys of the automatic music playing device are operated at a suitable timing. PSOLUTION: When an automatic music playing event occurs and a delay time dt indicating for delaying the START of movement is calculated to move a damper pedal 10 to a target position ND when a total delay time DT elapses after the occurrence of the event at a predetermined moving speed S. After the delay time dt elapses from the occurrence of the event (S330: NO), servo control is performed while a target value of servo control is sequentially changed (S360) to move it to the target position ND at the predetermined moving speed S. The total delay time DT is set so that all the pedals and keys provided in an automatic playing piano 1 are moved to the respective target positions according to the contents of the event within the set time.
