Thanks for the reply. Actually, I would rather get the file into Cubase first as I may want to add another instrument.
In any event, perhaps you could explain further. I may well have an addled brain today, what is the best process to get two mono inputs (actually the left and right channels of a stereo signal) into an RME to be two channels (left and right) of a stereo track in Cubase or Wavelab?
