No Signal to GarageBand
I'm a first time user with GarageBand and I am so confused. I have a Focusrite interface. It's all set up, my guitar is plugged in, I can hear my guitar through my headphones. But there seems to be no signal going into GarageBand. I have no idea what im doing and none of the tutorials iv seen have been able to help.
