Does anyone know where I can get an XG conversation cable as I upgrade from
a DSC100R to a DSC850? From the piano is 9 pins but to the 850 is 15 pins
(might be vice versa, not at the piano right now), and in talking with
Yamaha customer service, those cables are no longer available, and they are
not able to provide any kind of pin-out diagram so I could have such a cable
made. Suggestions?
