Sorry Casio, your manual and menu goose chase is a disaster, this thing is going back to the shop. Shame really, has some great sounds, if it would be a little easier to fine tune them to ones liking. I should have done more research on the model before purchasing, because the number of negative appraisals regarding the operating system would have steered me away. At least the dealer has accepted the return without hesitation, and understood my concerns regarding the button pushing required to do even the basic of changes, admitting that it is a complicated instrument. I have decided to go for the Korg EK50, a recent model from Korg. The reviews are excellent, and is claimed to be better than the Casio, and even the Yamaha PSRE463, which I also own. I hope I have better results with the Korg, as it is claimed to be more user friendly in the menu department.
