How can we expect you guys to be aware of superior capabilities or expect you to apply any effort that a open system keyboard requires...
Stay with your easy way out boards....and those that know better will continue to enjoy the superior open keyboards.. 
Yeh rich people. Not everybody can afford these keyboards. And I don't think the MS is superior to the Yamaha PSR S910 and Korg PA500. Have you ever listened to these 2 REAL arrangers.
