ABSTRACT:
An automatic performance device for a keyboard instrument such as piano, organ, cembalo and celesta includes operators such as keys and a pedal provided in a keyboard instrument for producing sounds, a target performance state designation unit for producing target performance information of the keyboard instrument, a real performance state detection circuit for detecting an operation state of the operators and producing a detection output, an actuator such as a solenoid for actuating the operators, and a control circuit for controlling the actuator. The control circuit detects in error between the detection output of the real performance state detection circuit and the target performance information, and generates an operator actuating signal by correcting the target performance information to eliminate the error and supplies the corrected operator actuating signal to the actuator.
