Hello, i recently bought a yamaha pro 9000. Yamaha support is not returning my calls, so i was hoping there was somebody else out there who can help me out. I can sample my voice into the 9000pro, save it as a custom voice and play it on the keys. However, when i turn off the keyboard and turn it back on... all my samples are gone. Can anyone help me find a way to keep my samples in the custom voice list? or something like that? thanks!
