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.

I have suggested this before that if each PG RealInstrument/Drum was sampled to Sforzando maybe ? you could then add create custom playing using midi to the RealTrack/Drum.
