Thanks guys. I went with the OS update downloaded to USB and then followed instructions on the YouTube video manual. Worked like a charm. After updating I starting creating a set list for an upcoming seniors concert. I've got 5 of my own song settings but I can't seem to change the STS voices. Also when moving from one of my set songs to another if I don't press STS 1 my keyboard sound will be the one I just used on the previous song. Is that normal?
