In a nutshell Donny, my Ketron SD7 sounds just as good if not better certainly in the onboard drums and basses. No doubt there are a couple of sounds in the Roland that will be superior to for instance the Ketron ( ac. guitars....) but I am not all impressed by this particular video. So what ? the guy has been at it for an hour to make a new style ? Everyone here in particular the Yammie guys have tens of thousands of styles, and so have you I guess. Many don't even alter the styles they have or barely but simply choose another (song) style to fit their needs, so be it, nothing wrong with that.
Sure, tweaking and tweaking your board to meet your personal needs and to get the best out of it is an imperative requirement. But sitting at it for over an hour to create just another style seems a bit farfetched to me. You will be meeting AJ shortly is my understanding. Let him demonstrate to you the power of the SD7 and even more so the SD9/90.
Don't get me wrong, the E-A7 is a very decent keyboard and the Dynamaix stuff is pretty good and sometimes very good. Added to that the fact that the cream of the crop here ( Don, Fran, you yourself etc.) use it on a daily basis is speaking for itself.
But imho it is still no match for the TOTL arrangers.
