Playing an MP3/WAV audio file
The CN37 digital piano is also capable of playing MP3 and WAV audio files stored on a USB memory device directly
through the instrument’s speaker system. This function is particularly useful when attempting to learn the chords
or melody to a new piece, or to simply play along with one’s favorite song.
