There is a workaround that we used to use with the older versions.

If you have any open tracks available in our song, Mel, Solo, perhaps Strings, whatever, as long as it is not being used already by the accompaniment, you can invoke a RealTrack Soloist for the entire song on each available track by RightClicking on the trackname and then select that particular soloist from the RealTracks picker list.

This does not involve use of the Soloist window at all.

Once generated, there will be a cacaphony of soloists on those tracks, all playing at the same time.

Not to worry, you can use the RightClick, Bar Settings, to lower the Volume of the Soloist(s) that you don't want to hear for whatever period of time - a few bars or an entire chorus.

So you would set one of these tracks to be playing for the first period of time while setting the others to be silent.

When you get to the transition point, you then turn the first soloist down and also turn the second desired soloist up.

Etc.

This can actually create a really cool illusion, too - with careful manipulation of the where and when, you can create that situation where one soloist overlaps another for a phrase or a bar or so, as sometimes actually happens in a live performance anyway.


And if you don't have enough tracks available inside Biab, consider moving the project over to RealBand and then do the same type of thing, using the Automated Volume or Pianoroll Audio Volume CC7 command to bring one track up and the others down while the song rolls through the timeline.
