I am searching for a manual that includes the actual diagrams of the programs for the roland jp8000. ex: the jp8000 user manual shows a blank chart of the actual instrument. Is there a book that shows the settings of the various pots and sliders for the jp8000 "performance programs"? This would be a great reference to go back to, instead of resetting the default settings, and losing the changes I have made. I have tried the Roland US .com site..no luck there. thanks.
