If the BDF will export to midi files, you could save your patterns as a midi file and import into Biab. You would want to then mute the drums in Biab.

You can also use the .seq (sequencer) button in Biab for imported midi files AFTER they have been imported properly. Since we are talking drums, they are probably on midi channel 10 and not much to do with using the .seq, unless they are scattered across several midi channels.
