Tony,
I get your drift.
I should say, my obvious zealousness for Yamaha, which would still be there even if I wasn't connected in the small way that I am, in no way lessens my fascination with other arrangers.
My favorite, outside the Yamaha Universe, is the Roland E-80, which is a real nice play and although it's not very portable because of it's weight, it would be a great home keyboard, and a nice compliment to things Yamaha.
The Korg PA-800 demos did not impress...sort of a murky area between the Yamaha polished sound and the Roland "live" sound, but not embracing enough of either to have a cognitive impact on me.
Perhaps I'll be having some of that humble pie once I play one and hear it in person.
Ian
