A sharp is additionally displayed (SCl2) in the case of '1' and a flat is additionally displayed in the case of '2' (SC11). Further, whether the value of an A register and the value of a pointer (z) are equal or not is discriminated (S13). Whether the value of the C register is either of '0' or '1' is discriminated, if A=z is attained and when display processing to all the notes constituting the chord or the note of the single sound is completed (SC15).
