I'll give a first guess that you can do it by chaining the equipment. Most MIDI devices have a MIDI Thru, so connect the source to MIDI In on the first device, then MIDI Thru to the next device. The drum machine should in theory respond only to signals on MIDI Channel 10. Look for a way to mute Channel 10 on the other device.

If your question is, can BIAB specify two different MIDI output devices, the answer is, to my knowledge, No.
