Claurett, When I referred to the BIG performance, that included the "auto" arranger. The keyboards today have great styles and yes, re use our own and modify the factory styles. These same keyboards also play Standard midi files and will show lyrics of thefiles on screen[this surly can help with a "PRO" performance..Some prefer to use "STYLE" arrangement play over SMF use. As an example it allows the musician the option of extending a tune[ late dancers on the floor], and more expression freedom. Today's technology allows us to take a SMF and convert it to a "Style arrangement"..How can a Pro not want these capable ways to improve their performances? Fran
