Actually it's neither because I used to have both keyboards and the 510 / 520 were classed as MOTL in those days if i'm not mistaken! No what you're looking at is a very lowly PSR 220 because I bought one for my daughter when she was 9!!! I'll post a pic just to prove it!!!
It's amazing what you can do!!
