Starkeeper,
Sadly I haven't had the chance to demo it yet. However, I'll be up north for my sisters wedding next week and I was told that there's a store up there that has one on the floor

I have talked to people who own the unit and are COMPLETELY blown away by the synth. One guy was all set to buy the Motif ES6 before he demoed the Alesis. He said after 20 minutes with the Alesis there was just no comparison when it came to features and price.
The reason I'm considering the Tyros classis is because my set up is going to consist of one top quality arranger and one top end synth. I've been eyeballing the Tyros as my arranger, and will come to a conclusion if I get to demo the Alesis next week.
