Dan, I have done that a number of times, i.e. converted my audio guitar to a MIDI track. What I sometimes do is to have the MIDI track play simultaneously with the audio track with the MIDI track having a different sound like a music box, zither, bells, etc. One can get some very nice sounding tracks this way. YMMV

Whenever I get something stuck in the back of my throat, I dislodge it by drinking a beer.
It's called the Heineken Maneuver.
