I've had Logic for a week now and still am too dumb to figure out anything so bought the first tutorials.. Unfortunately it doesn't seem to answer my first issue which is plugging in to it. I followed posted instructions to make the aggregate device (using Audio Kontrol 1), and now I get output but the input doesn't work anymore. (It works fine with Audio Kontrol as input but obviously then I get no output.) Surely I must be doing something stupid but I'm not sure what. For the aggregate device I just simply put Audio Kontrol as the input and Built-in for the output. I didn't change anything else except to try putting the clock on either with the same result. Any ideas?
