I'm trying to understand the helix as an audio interphase. What I don't understand is how it can do 8 in / 8 out, when the back side only has two 1/4" inputs and one XLR input. That's three inputs into the helix. Based on that, I would expect the helix to be able to output three separate audio channels. Where does the helix pull the audio from in order to output the other five separate channels, that are claimed (8 in / 8 out)? I could really use an 8i/8o audio interphase and effects unit, to go along with the unit that I use for sequencing tracks (Akai MPC Live). The MPC can send 6 separate audio channels. If I could route them all through the helix simultaniously, (put some effects on them) and then output them to a laptop - that would be great! That's what I expect to be able to do with a 8/8 audio interphase. But it seems that the helix lack the necessary inputs.. So I don't understand how it can output 8 channels.. P.S. I obviously wouldn't buy the helix just to use as an interphase. I would use it mainly as a guitar and bass effects processor, of course. But since I read that it can also be used as an audio interphase...
