It wouldn't work for me (unless I don't understand the XS well enough).

I have hundreds of custom styles that I'll use over the course of an evening and I change them at less than a moments notice. I typically will do a 1.5 to 2 hour dance set without a single second of dead air. I change the styles extremely often - sometimes a few times in a single song to keep things as fresh as possible. (You have to hear it to understand it. I guess you can look at it this way - for me my whole keyboard is one style with one thousand variations, and each variation is in a way its own style so that I have one thousand styles with no variations...) For me to change a multi each time I change a variation or style ain't happenen.
