Hi Ulrich: Since many (most?) dealers (at least here in the US) aren't equiped with their own 'in house' repair department, I assume that the dealer would then just refer Tyros owners to a Yamaha factory authorized repair facility to perform the flash-able upgrade. Unfortunately this still means being without your keyboard for several days (or possibly weeks) as you wait for the repair technician to get to 'your' board. This isn't an option for gigging musicians who relies on their kb to make a living.

There's got to be a BETTER way to handle this situation. Since the Tyros already supports USB PC/keyboard connectivity, I would think Yamaha could just as easily provide Tyros owners with flash ROM-able OS updates on CD and allow them to download it to their keyboard from PC via USB. Afterall, if a flash ROM-able OS update is possible at all, wouldn't it be performed this SAME way at a repair facility? From a cost standpoint alone, it would make more sense for Yamaha to allow the end user to perform OS upgrades themselves. - Scott
