I'm trying to record my Hammond keyboard into garageband. I've connected a quarter inch cable from my keyboard to my interface, then connected my interface to my computer with a USB chord. In my Audio MIDI setup I muted the built in microphone, and it has registered my USB audio. So thats good, I think. When I go into garageband I've chosen New Project, record using a microphone or line input, input one, then create. When I push the record button and the keys on my keyboard nothing happens. What have I done wrong?
On the back of my keyboard theres the output (which I have my quarter-inch plugged into), Midi outputs, and a USB output. Should I potentially be using a different chord?
