To save anyone from further embarrassing themselves the video was actually posted by Bachus in the "The (multi)pads on the Casio Mz-x500" thread here. So it wasn't in this thread at all. It was fair for Bachus to point out that it had been posted before (although he neglected to say that it was HE who posted it and that it was in another thread) but I feel no need to apologize for posting it again here since others may have missed it there as I did.

In any case to get back to discussion it seems clear that Casio is not aiming these arrangers primarily at "typical" arranger players, at least not ones in the US (the rest of the world is a big market). So if you're one of those players and you're not interested they're probably not too upset about it.
