I'm pretty sure I'm going to buy the S910 when I get it for demoing, and I would love to have the Prelude to add the Roland sound to my kit, but the lack of Style Assembly (being able to swap style parts from the same or other styles) on the latter, is a deal breaker....so far.

Maybe there will be an OS update to allow this essential (for me) feature.

One of my favorite past Roland arrangers, was the E-70...the Prelude kinda reminds me of that 'board, which was about three times the price of the Prelude when new.
