ProducerYoda, RB, and BiaB allow Drag and drop, with for me works very nicely in Sonar, Reaper, and Multitracksudio. Just click the DAW button and either of the programs will change to a smaller window, and you can drag the tracks over one at a time, all together or to a folder on desktop and move from there. They should line up, they do here for me.

What program do you move them to?

BiaB you can export the file from Band in a Box as a midi or midi with audio, and open that in cubase. Until BiaB develops Rewire that will be the way.
