No. As I'm sure you've already predicted, the other lightweight portable arranger w/ 'built-in' speakers I'm considering as a 2nd keyboard is the S910.

The draw ofthe Roland Prelude is new sounds/styles, a much lighter keyboard weight, and substantially cheaper price, while the S910 offers file compatibility/exchange with my Tyros2, and an operating system I'm more familiar with.

I'll of course share my experiences with whatever secondary arranger unit I might eventually get. In the meantime, Tyros2 continues to satisfy as the primary arranger axe.
