Dan, your SGU file downloaded and loaded into my BiaB test system fine. Yes there is fret noise but no more than I would expect. I believe tempo mismatch is the bigger issue.

As you know the #3113 even16 nylon guitar RealTrack you want to use has a tempo of 60 bpm while the song is using 117 bpm.

I believe you should audition similar nylon RealTracks created at a tempo closer to your song. Have you tried #3646 FingerPickin' IndieFolk even16 nylon guitar at 100 bpm?

There are two suggestions you may want to try if you want to continue using #3113: (A) Change the song key from Am to a different key and regenerate. The program will use different RealTrack material. (B) Go to Preferences > RealTracks and turn on: (B1) Allow RealTracks substitution based on tempo and (B2) Tempo/Pitch stretching quality is set for high. Then try changing the tempo from 117 to 114 and regenerate and 117 to 121 bpm. Again this will allow the program to use new RealTrack material you may like better.
