Hey Mike.
This is a catchy tune. What is the style?
I think I recognize the style from one of the Baartman's demos (Robbie Williams' "Let Me Entertain You" I think was done with that style).
In terms of suggestions, I think all of us keyboard players must strive to emulate the string and wind instruments so that they sound more natural. SA does a lot for this already but we must adapt our playing style.
Unfortunately, this is easier said than done and I am working on this myself. For electric (esp. distort) guitar I found using pitch bend to bend up to the target note helps a lot to make sound more realistic. For sax, I found phrasing to be key (remember, player needs to breathe), playing fast notes legato, and limiting use of sax to a shorter solo. This way, there is less time for listener to notice that the sax is coming from a keyboard ;-)
Best of luck from a fellow T2 player!
