I have an M-audio 410 box and I'm using protools(m-powered edition). I was wondering if it's possible to purchase a unit (maybe one of those berringer a/d units) and hook it up through the adat/lightpipe connection in order to get 8 more inputs through the unit? I have a mackie board to use for preamps, so that isn't a problem. Any other suggestions? All input would help! THANKS!
