PROBLEM TO BE SOLVED: To enable a listener to listen to the playing performed even at a remote place in real time with an automatic playing piano which executes automatic playing in accordance with electrical signals by transmitting and receiving the electrical signals through communication circuits. SOLUTION: With the piano on a signal transmission side, switches 6 to 10 are put to respective detecting circuit 1 to 5 sides and a switch 23 is put to on and a switch 24 to a recording circuit 12 side. As a result, the playing data signals detected by the respective detecting circuits 1 to 5 for a keyboard SW, keyboard touch, string amplitude, sustaining and silencing are inputted from a control section 11 to a signal transmission and reception circuit 25. While these signals are temporarily stored in a memory 26, the communication speed is matched with a signal transmission destination and is synchronized therewith. The playing data signals are transmitted via a modem 27 to the communication circuits. With the piano on a signal reception side, on the other hand, the playing data signals received by the signal transmission and reception circuit 25 via the modem 27 are temporarily stored in the memory 26. The control section 11 operate respective driving circuits 16, 18, 20 and execute automatic playing. |
