摘要
A set of formation data codes (FRM1), which includes action event codes (AE1, AE2, AE3, AE4) and duration codes (TD1, TD2), is loaded in an automatic player piano (30), and a controller (3a) interprets the action event codes (AE1, AE2, AE3, AE4) for driving the solenoid-operated key actuators (20); since the solenoid-operated key actuators (20) slowly push the associated keys (31a, 31b), the hammers (32) do not reach the strings (33), and any piano tone is not produced; the plungers (38) make the keys (31a, 31b) sunk to different depth so that the keys (31a, 31b) are laid on a artistic pattern; the controller (3a) sequentially changes the artistic pattern, and offers an artistic visual expression to the audience.
