ClassicMan,

You're gonna' hate me because the answer is Yes and No.

Yes because you can use the F5 bar settings to assign different soloists to different bars. Using your example at bar 1 you assign a clarinet soloist, at bar 9 an acoustic guitar soloist and a trumpet soloist at bar 17.

No because regeneration is all or nothing in Band-in-a-Box. If you like the acoustic guitar soloist but don't like the clarinet or trumpet then what are you going to do?

One way around this dilemma is to use the Band-in-a-Box audio recorder to record the audio you want to keep, regenerate until you get another soloist you like, record that audio and use the Band-in-a-Box audio merge feature to combine parts.

To make things easier, record the instrument tracks like bass, drums and piano, make the recording a performance track and move the performance track to one of the no longer needed bass, drums or piano track. That leaves the two other tracks for soloists.
