Amelio,
BOY are you lazy! One quick push of a button to configure the board to your liking is too much? Maybe someone from Yamaha can come to your place before you want to play and turn it on for you....then set it all up so you don't have to exert yourself.
I'm really sorry to sound cruel - this is all in jest
I just think it sounds like such an easy workaround to get what you want. These keyboards are ALL about buttons !
