As Steve pointed out, the pitch remains constant when BiaB timeshifts the music, but the vibrato starts being cartoon-like. The flute has similar issues.

There's an option for choosing a different time base (Half/Normal/Double) that you might want to look at. You can find it in the RealTracks dialog in the upper right side. The instrumentalist plays twice/half as much to fill the space, but you don't get the problem of time distortion that you have now. It's a pretty good solution.

But I also agree with other folk, in that you've got a very solid song, and there's really no need to add all that guitar to it. It just adds busy filigree to a song that's quite good just fine without it.

Vocal control, you say. Never heard of it. Is that some kind of ProTools thing?
