Headphone mix cubase 5

Hello!

I wonder how I shall do to be able to have a separate mix that I can use for listening as Im recording, and be able to switch between the two mixes? So I don’t have to change the channel levels in the main mix? Do I have to use the “control room” funktion for this? I only use one pair of headphones. My soundcard is saffire pro 26. Hope this makes sense!
