Thanks, Stan.

"Soloing outside" is a legitimate option under SOLOIST. I THINK it has something to do with where BIAB "places" the soloist in the mix. Not sure, thus the question.

The soloist feature in version 2013 is a marvel of programming. I love it! It also has a "medley" option (on selected soloists only) where several instruments will trade 4s. Very realistic.
