PURPOSE:To enable even a beginner to designate easily a code by providing a code discriminating means to discriminate whether a detected fret operating position is the one operated in conformity to specified open code form or not based on the compared result of the fret operating position and code discrimination information. CONSTITUTION:When a player executes fret operation by the open code form, a fret operating position detecting means detects this fret operating position. Subsequently, the code discriminating means compares the fret operating position detected by the fret operating position detecting means with plural pieces of the code discrimination information stored in a storage means. Based on this compared result, it is discriminated whether the detected fret operating position is the one operated in conformity to the specified open code form or not. Through this action, when the player executes the code designation by the open code form, the code designated by the open code form is decided. Thus, even the beginner can easily and quickly execute the code designation by using the open code form. |
