I've been trying to design a keyboard that can be used with the feet - something that I can play like dance dance revolution, while playing something else with my hands (mandolin), thus making me a one man band. Figuring out what a good layout would be is the first step and so far everything I've thought of either lacks useful notes, is too big to reach useful notes, or the keys are too close together. If anyone has ideas on how to do this I'd love help. (or better yet do this as I don't have must time to work on it)
