Hey Glenn, right as rain! It was the visual representation I was referring to haha, apologies if I wasn’t clear enough on that. Will be wary of Quicktime from now on 😉 Before that I had been trying hard to find a specific instance of my problem, but alas it was apparently so basic I couldn’t find any. As for the monitor and IO box and all that… I’ve to confess I’m really just a dilettante.
Anyway, a million thanks for pointing that out! It helped me get through my dilettante activities in no small part 😛
