In fairness, I have heard few 'live' SA2 sax demos that came even CLOSE to the factory demos, which are sequenced (but use style play as the jumping off point).

The timing and phrasing is MUCH more critical once your sax sound actually CAN do legato and staccato tonguing. And few arranger players I have seen play live have the requisite skills to pull this off.
