Further, the processor identifies, based on the first information, the open/close state of the tone hole or virtual tone hole for the key operation detected. Further, the processor determines, based on the second information, the note for the identified open/close state of the tone hole or virtual tone hole. ## Claims ### Claim 1 A conversion-to-note apparatus comprising: a key which is operated by a user;
