Tonewheeldude,
There were no special voices I wanted or needed. The questions arose on a UK forum where people are trying to decide to buy or not to buy a SD7 or SD40 module. I own 2 SD7 keyboards and was trying to help them. The group wanted to know about backward compatibility much like Yamaha keyboards have had forever.
Seems like Italy would see the advantage in providing full backward compatibility with their products.
