Nathan, you said:
unique track exports can easily export unique BB sounds by assigning

Actually, I don't know if this is possible---at least I don't know how to
do it. You can assign unique BB sounds to corresponding FX channel, but as
far as I know, that's only for applying FX. What I see in the "mixer" view
is the FX channels. The tracks I export are the ones you see in the song
view.
Am I missing something? Is there a way to assign a BB sound to an
individual song track?
