Question 1

How can I tell whether a song can be played on the N20 or the N40?

In the online music library on the official website or within the app, each song clearly indicates its note range (e.g., 15, 20, 30, or 40 notes). If you have an existing song and want to determine which series is suitable, please refer to the following:

N20 Series: Suitable for general pop songs that do not require accidentals (i.e., the white keys on a piano).
N40 Series: If the song includes chromatic notes (i.e., the black keys on a piano)—for example, songs in minor keys, certain classical pieces, or film scores—then the N40, which spans nearly four octaves, is required.
