Thanks for that John. I know that you enjoy programming. Maybe it's time you do this on a properly commercial basis. There are dealerships for korg for Yamaha for Roland all over the country. Could you bundle your resources as part of a package that dealers could then sell with the instrument . Perhaps part of the deal could involve them loaning you a keyboard for short while. It would be a great way for you to spend considerable time on the instruments and decide which one you liked best .
