Firepod, Mic And Logic Express Options

[Rics]

Hi, Im a real novice starting to use logic express. I know that once I learn the basics it shouldnt be too difficult to figure out how to do stuff with it. I was just wondering if anyone knows how to set the audio input to channel 1 on my presonus firepod. Iv figured out how to use midi a small bit but the audio in must be set to internal speakers on my new 1.67 PB. I can record vocals through the internal mic, but its not of too much use to me when I have a decent mic plugged in to my firepod. I changed the system preferences sound panel to presonus firepod for the input so i dont think thats the problem. If anyone knows how to change the input to the firepod I'd be greatful. Cheers
