Could you also list how you have the tracks set up in cubase
I'm hazarding a guess, but what it looks like to me, is you are recording the RCA out off of the M-Audio card. along with the mic input, and everything is getting recorded into the mic track
If you have 2 tracks (one for the backing, and one for recording the mic) Make sure the backing track is -not- armed, but do set it to be monitored.
Hope that helps. And if I've just further confused you, let me know and I'll try to answer questions.
Edit: Actually, I had a mistake in my reasoning. Even if you disarm the backing track, it will still record the stuff off the RCA. But, to get it back into the M-Audio Card, it looks like you have to use the RCA jacks. So the problem is a little complex since you don't seem to have inserts or subgroups to record off of to go straight into the M-Audio Card.
Looking at the board's CD/Tape aux and mix sends, something you might try is pressing the CD/Tape to CTRL so that the tape inputs are monitored, but depress/deselect the CD/Tape to Mix. That might prevent the tape input from being recorded. I think....it's worth a try anyway.
