Can't connect Lexicon Alpha audio interface to logic!
I've just got this audio interface and I plugged it into my laptop using the USB port. Logic recognises it and I've selected the interface as the input. However when I create a new audio track and plug my electric guitar in, logic doesn't pick up any sound at all! I'm sure I'm doing something wrong so some help would be greatly appreciated.
