Chuck, not sure that I am the most knowledgeable about this topic, and I assume others will chime in. But here's what I do. Keep in mind, I'm using midi only with multiple hardware, software synths, and Sonar X1d. I'm not sure if this is similar to your setup.

I'm using a MOTU multiclient ASIO driver in all (BIAB, RB and Sonar), which I assume is the Steinberg wrapper, I can run BIAB, RB and Sonar all at the same time...with each playing a different song. When I do want to move tracks, I click on the "plug in mode" button in RB, this puts RB in the drag and drop mode. I then highlight the RB track by clicking on the track number and holding the shift key and dragging it to the appropriate Sonar track.

I've had some issues with getting the tracks to line up exactly where I want them and get frustrated at times that I cannot move multiple tracks at the same time to avoid this. Still it does work.
