yamaha piaggaro np-11 midi keyboard

helllo, i have cubase 6’ with an rme400 sc. i just got a yahama piaggaro np-11 and i do not know how to add it to cubase. i selected another yamaha device as the np-11 wasnt in the drop down. i went to the yamaha website and tried to download their usd drivers but that didnt help me.

im sure there is a simple answer so any help would be appreciated.

thanks, im new to this.
