PURPOSE:To voice explanation and to control various equipments in addition to automatic play, by inserting voice information and control information into an empty word or frame. CONSTITUTION:Among data demodulated by a demodulating circuit 2, a word used for the automatic play of a piano is supplied to a driver circuit 3, which converts serial information to parallel one, frame by frame, at the same part A with a conventional piano coder, thus obtaining a solenoid driving signal for operating a solenoid group 4 selectively. An empty word of the data is used for control over voice information and various equipment. At a voice playback part B, data and a clock are obtained from the demodulating circuit 2 and a driver circuit 6 performs serial/parallel conversion to obtain voice components, which are synthesized 7, amplified 8 and voiced 9. At a control part C, the data and clock are obtained from the demodulating circuit 2, and the driver circuit 10 performs serial/parallel conversion to obtain control signals for various equipment. |
