Apogee Jam Help!

Hi,

I have recently purchased an Apogee Jam from Apple. I wasn't able to figure out or find anything to help me record Audio and Video at the same time USING built-in effects in GarageBand. I want to record video (from iSight) and record audio (Apogee Jam) at the same time. Although I think I found a way to do it in iMovie, it doesn't allow me apply effects.

So basically, I would like to record Apogee Jam and video at the same time USING effects.

Any help would be much appreciated! Thanks!
