Thank you for the response. Regarding "Studio One will still show a picture of the AudioBox USB 2x2 for any given AudioBox unit connected to a PC regardless," I am looking at the the screen on my HP Pavilion and S1 clearly shows the pictures of both the AudioBox USB 2X2 *and* the 1818 VSL, *and* it allows me to chose between the two. It recognizes and offers as a choice both interfaces. On the HP Envy, new computer, it does not -- It is like you describe: only shows AudioBox USB regardless of which is connected. So I guess what you are saying is that selecting "AudioBox" as the interface under Studio One > Options in the case where it does not specify which AdioBox type really does not matter? It is essentially a generic selection, not specific to model, and by selecting "AudioBox" I am okay to run either the 2X2 USB *or* the 18181VSL just based on whichever is plugged in and I am using at the time? It is simply something I have to get used to seeing but does not effect operation? Again, thank you so much for the quick response!
