Hi James. I agree with Tapas's posting above.
Your sounds are excellent for the Korg instruments and I appreciate you are going to make the piano assault freely available to the Yamaha users as well as existing Korg owners. There's not many people who would be as generous as yourself.
Best wishes for whatever you have planned for the Korg and Tyros 2 in the future. I'll look forward to your next update on Synthzone or on your great web site.
