Simon, I am listening to Smooth right now. I like the drums: very crisp. The guitar is more or less the same as on the 9000pro: good but not "bad". The brass are good but maybe it would be better to layer three or four sounds to simulate the impact of a real horn section. I like the organ sound. The guitar solo is good and the organ background very appropriate. After the fill and the variation the brass "kick" more and the whole song is better and I guess that you sensed that because your solo is more intense, like you too were being driven by the beat.
The finale is very good.
OK: congratulations Simon! (clapping noise in the background)
Now I am waiting for the "real" expert's opinion: Eric, where art thou?
