Mike,

I like it better when you gave the harmonica a break and let the other instrument play a while. (what was the second solo instrument, anyway? It sounded like a guitar, but you didn't have any MIDI guitar tracks listed, and it didn't sound like a real track)

You had some pianos listed, but the playing itself used techniques (like vibrato and slid notes) that would be more indicative of a guitar than a piano)

By the way, that is a very realistic harmonica patch! I have a couple of fairly good hardware synths and the harmonica is nowhere near that good!
