Are you changing instruments with F5 at the bar in question? I think you cannot do what you want in Band in a Box but need RealBand for that. You make multiple solos and mute and unmute then on the many tracks you get. Midi soloists in Band in a Box are limited to one as far as I know and that's with the current version. An upgrade won't fix that issue, at least in my mind.
