I've never worked with the delta 1010, so I'm not completely sure about what your asking....but I'm thinking that you just want to plug your instruments into a different location....if so, I don't see why you couldn't use a patchbay, or if you wanted to spend a little more money, you could go with a mixer. I don't see how that would change your "wires coming from nowhere" problem though because you would still have to run the line outs of the patchbay or mixer to the soundcard.
