Whilst this is a very useful function if you want to keep all the drum mixing inside Cubase, there seems to be a bug, as the Aux 1-4 channels are NOT exported to Cubase. You do not get any of the reverb (mostly) or other effects from the four AUX sends in the Groove Agent mixer exported into Cubase.
Could someone at Steinberg please verify this and if it is a bug, have it corrected?
Many thanks
