Bsharp,
I did the same with my 740, so now I use it to display all these changes and manually put them into the 2000. I don't see a way for the 2000 to recognize the 740 registrations. I have also noticed that the guitar and pad sounds from the 740 styles need to have the volume increased. Additionally, the 2000's styles played in the 740 need the guitar and pad volumes decreased to sound like the original.
