• a sound source part produces and outputs a predetermined musical sound based on the detection signal output from the hit detection part,
• the sound source part including:
• a hit position identification part identifying one of the hit positions based on the detection signal output from the hit detection part;
• a threshold value setting part sets a threshold value according to the hit position identified by the hit position identification part;
• a musical sound production part produces and outputs a predetermined musical sound based on the detection signal which has exceeded the threshold value set by the threshold value setting part,
• wherein the threshold value set by the threshold value setting part forms a gradual decrease line that gradually decreases with a lapse of time, and
• the gradual decrease line is set individually for the hit position identified by the hit position identification part.
