My sentiments exactly Jim. Having owned the Motif ES7 for a 'short' while, I can concur with you wholeheartedly that the Motif ES is mainly a "Studio" fixture and I would dare to say not even recommended for live performance. That was one of my biggest chagrins with the ES; that it's not suited for live play IMHO. And having just recently bought a Tyros I have learned firsthand that the Tyros is, was, and always will be a Live performance Keyboard! That is the area it "really" shines in. The layout on the Tyros is practically perfect for Live use. And there are tons of superb Voices in it too, including the Mega Voices of course.

Someday in the not to distant future I think there will be Workstation Arrangers. Notice I didn't say Arranger Workstations but 'Workstation Arrangers'. The Motif ES, and Roland Fantom S are laying the basic groundwork for that concept IMO. Down the road the line drawn between Workstation and Arranger will be transparent and indistinguishable, having become one in the same IMO.
Best regards, and congratulations on your new Board!
