My suggestion... HOUND YAMAHA!!!!!! If everyone who buys the Tyros starts hounding Yamaha for an upgrade via USB... They might jump on it.. I remember me and SOOOOO many users on another keyboard forum for one of Yamaha's synths wouldn't let it go.. Finally Yamaha was sending the upgrade chips for free.. Hell the accidentally sent me two sets... Just stay on their hind ends about it... Get enough people complaining and they just may do it...
