The problem is unlikely to be the Edirol or the SD2. It may be the way the Thru or Audio channel is set up though.

A further thought before we abandon anything: Which sound do you think lags behind the other?
Does the MIDI output play ahead of the RealTracks, or does the MIDI output lag behind the RealTracks?

Does this happen with playback, or with live input playing on your keyboard, or both?
