I just saw an article in my email talking about how to dual mic a single cab. I tried this in Wall of Sound since I didn't want to turn my Studio on. But I cannot seem to find how to get a Mic A and B in this interface. The only thing I can do is stack multiple cabs. But the article talks about dual mics and a single cab. Is there a way to do this in WoS? (I have latest version, Mac).
