That has been my question to the Apogee folks, the answer from Apogee is always re-directed to the Logic folks.
The GUI for Apogee is Maestro, according to Apogee there are no settings w/in Maestro that will change how Logic 8 will output audio.
I need to back up a bit and re-think some other choices/settings that I have made in Logic. 1st. is the universal track mode setting, when U.T.M. is turned off, and I choose a send on the ch.strip, it offers; no send, output, and bus. If I choose output > mono, I have access to individual mono channels. When U.T.M. is turned on, the choices are; no send, and bus. I guess, I need a better understanding of universal track mode.
Oh, and when U.T.M. is off, a mono signal arrives at the x-desk, w/out any hard panning.
