This is really a question for the Apogee folks, but heck, it's the weekend, so I thought I'd try here. I just purchased an Apogee Duet for some basic recording into GarageBand. It works fine when using the Instrument in, and Guitar Rig as my sound engine. But when I connect my Pod XT into the XLR ins, I get no sound from the Duet's headphone out jack. Maestro Main and Mixer register the Input signal, but there is no Output signal. The LED's on the Duet itself show no signal. If I go ahead and record into GarageBand, everything's fine on playback thru the Duet's headphone jack, but not at any other time (ie, I can't monitor my playing while recording). Any help would be greatly appreciated. Thanks!
