You just save the BB Chord Output to MID, Import it in the Melody or Soloist ch9 only, transpose the track up 2 octaves. See the link above for the Tips n Tricks guide.
The thing with UJAM Instruments/Drums you can use all the recorded real phrase playing and use your own GM midi with it to create it just how you want.
