Logic Pro 9 automation quick access question



I'm not sure if this is a hardware or a Logic question. I have an Edirol PSR-800 control. It was lots of knobs and sliders that work perfectly well with Logic's automation quick access. I've also recently purchased a Roland EV-5 expression pedal which I have plugged into the controller on the side of the unit exactly where the manual tells me to plug it in. However when I move this pedal during the automation quick access process, Logic doesn't see or respond to it.
