• “PIANO” contains folders named “MUSICLIB” and 
“RECORDER”.
• To transfer a user song to the digital piano from your 
computer, open the “MUSICLIB” folder and put the 
song into one of the numbered subfolders (61 
through 70). Each subfolder corresponds to a Music 
Library number: Subfolder 61 to Music Library 61, 
and so on.
• The files in the “RECORDER” folder are songs that 
have been recorded with the digital piano’s recorder 
function. You can move files from the “RECORDER” 
folder to another location on your computer, and you 
can return recorded song files to the digital piano by 
placing them into the “RECORDER” folder.
