I think the bottom line about arranger players is, TBH, most of them don't really care too much about the band. Listen to the vast majority of user arranger demos, and you hear the backing utterly swamped by what the player is playing. So, all in all, I think the Audya is up against it, having a GREAT live backing sound, but RH voices that don't quite match up to the best of SA2 and the like.

That doesn't appear to be the priority of the majority of arranger users!

And yes... pretty much stumped thinking of any 'gospel' that sounds like this. 'Soul', yes, but gospel? Not really. Bit too busy, TBH, from the drummer. Maybe as a set ender or showstopper, but if you are planning on a whole bunch as busy as that, not really sure you know your target buyer that well... LOL
