PROBLEM TO BE SOLVED: To make improvable the visual effect by providing a control means, etc., which controls a sound output means and also controls a display means so that predetermined display places illuminate corresponding to the detection of a periodically generated sound by a detecting means. SOLUTION: A spectrum analyzer IC28 which detects the sound generated periodically at the tempo of music is connected to a microcomputer 26. To the microcomputer 26, an operation part 24 and a display part 30 are connected. Further, a sound output IC32 which selectively outputs multiple rhythm patterns constituted by combining specific musical instruments and musical instrument sounds is connected to the microcomputer 26. The microcomputer 26 when judging that a beat sound has been inputted controls the sound output IC32 so as to output a 1st effect sound determined corresponding to the beat sound and makes determined display places of a display part 30 blink corresponding to the beat sound. |
