When you purchase a yamaha keyboard the dealer has a supply of what is called "Survival Kits". They include a A.c. adaptor, foot pedal, cd with software for downloading styles and Yamaha midi's and an extended warranty for two years. I beleive they run about $39.00. Dano has them along with G.C and other dealers. Tyros, PSr 3000, Tyros 2, etc are some of the keyboards that you can purchase the kit for. Bob L.
