What they said. And add this- I don't have a conrol room at all (wish I did), so for me, the biggest problem isn't mixing. I mix in my nice treated room. Monitoring is done with cans while tracking, and yes, that can pose problems. My big problem is bleed from the control station to live mics. I can't use any piece of equipment that makes any noise. It goes right down to the littlest things, such as my watch, which I have to take off and leave in another room.
Most of what I'm tracking is acoustic instruments and voiceovers, not live rock, so all I have to do to mess up a track is drop something on the floor. And the nice engineer (me) has to breathe as if I was standing in front of the mic, because basically, I am. Oh well. You have your problems, and I have mine.-Richie
