Since you are using the Windows version of BIAB, you can use the multi riff feature in RealBand to generate a duplicate midi track of another track. Select and area or entire track, select multiriff and from the multiriff window that appears, select one of the seven options, generate the multiriff and when it creates the new multiriff, it generates a midi track in a lower track. Assign a midi patch to play.
