There is a "DAW" button in Biab that is used for drag-n-drop from Biab into another music application. Using that button allows real time drag-n-drop where you don't need to export anything first. You simply drag the Biab part, AFTER you have generated the part(s) in Biab, into the track(s) of your other sequencer etc . . .

Check the tutorial videos or the help file on how to use it as intended.

That DAW button allows a quicker step to get your part(s) into another music application, which many use here for mix-down, mastering etc . . .
