I have been recorded with the Audiobox 1818vsl forever, but recently decided to get a Digimax D8 to add additional inputs. I am on a Mac, using Logic Pro X. I can get the inputs to show up and my Mac acknowledges them as being ADAT inputs. I can also create an aggregate device etc. but in Logic Pro X I get no respons from the ADAT inputs. If I change the setting on the Audiobox from "Internal Clock" to "ADAT Clock" I lose all response. What am I doing wrong?
