Wow, I can't believe I have such a bad case of CRS. I mean, I USED to be able to do this but forgot.

Anyhow, no, it's a REALTRACK. What I've done is (1) clicked on "Add RealTracks", (2) selected a RealTrack solo by Brent Mason (guitar) and that's it. So when I click play the song takes a moment to generate with the "solo" but the solo can't be heard. Frankly, I THOUGHT that was all I had to do but, obviously, I'm leaving out another step or two. It's just that I can see the guitar tablature with the "played" notes being highlighted (at least I remember how to do that!). I just can't hear it.
