Hopefully that is what you were looking for.
I normally keep the default MIDI output set to the DLS Synth.

Then when I want to route a BIAB MIDI track to another program, standalone synth or external device, I use that "Select Port/ Instrument" dialog (in the screenshot of above) to route tracks MIDI where I want it to go.

The biggest gotcha with that, is that if you want to send MIDI from BIAB to another program (say sforzando), you have to launch sforzando before BIAB so it's MIDI input is seen by BIAB when it launches.

Hopefully that makes some sense the way I said it. smile
