I'm having difficulty routing a previously recorded track through a Fireface UC, then through an outboard compressor, and then back into my DAW (Logic). I am using Logic's i/o plugin and successfully get sound through the UC and the compressor. I noticed, though, that although the track in question is mono, the signal is far stronger in the left speaker. If I then mute all channel strips in Logic I still have an unprocessed signal coming through the left speaker. I assume this is because I am using input and output 5 on the UC. (It might help to upload an image of my TotalMix window, but I don't see a way to attach images.)

The logic behind this is driving me batty since I'm quite sure this is a user error. Can anyone suggest what routing error I have committed? Better still, is there a way to use outboard processors without resorting to Logic's i/o plugin? Is there a way to accomplish this within TotalMix? (If so, is there a more detailed resource than the manual?)
