I just read that entire page and I still don't understand what the box actually is, what it does, where it sits in the setup chain or how it interacts with everything else.
Is that bad advertising or am I just dim? You don't have to answer that question.
No it's not you. I had to research it a bit too. It's like a super usb and midi hub with ethernet too!. As I understand it anything plugged in can be routed to anything else plugged in, in any/all directions (except the power supply lol). Looks like a pretty powerful routing solution.
