Yeah, perhaps the "dumbed down" DGX is not what you, or other pros are looking for, but it sells very well...it is considered a piano based arranger as opposed to an arranger based piano, so the auto functions aren't emphasized.

I think they'd do remarkably well putting the S900's or even the S700 arranger engine in a DGX...the R&D for the former are probably already paid for, so it would be a natural, and give the DGX an even bigger edge against it's rival..the market is pretty well dominated by Yamaha and Casio, so it's very competitive.
