No complaints here and no problems, as yet, with the S970. I play out several times a week with it. Prefer it much over the Tyros 5 for hauling around and small dinner parties. Just wish it had an onboard speaker system with the power and sound to rival my Bose setup. Wouldn’t that be something in a keyboard? Probably cost a fortune. Imagine being able to play live gigs without an external sound system, mixer, wires, and all the rest.
