I'm wondering if anyone has figured out how to dis engage the mod wheel on the piano sounds? I actually sent back the first 560 I bought because when I was on the phone with Casio they didn't even know why this was happening and told me to exchange it! As I was waiting for my new one to arrive it occurred to me that maybe i=t was the mod wheel but why would that ne enable on the piano sound? Makes no sense and the vibrato doesn't really turn off the whole way even if you have it down. Any suggestions?
