I think it would help much if Foot controllers (FBV EXPRESS™ MkII, FBV SHORTBOARD™ MkII and FBV) had analog iputs to convert it into digital and send it via, through the exsisting usb output.

     You'd just need one device for playing, recording with pod farm and/or other devices; would be more compact too as the sound card won't be needed along with cables and yasier to use and configure. It may be more expensive, as customer buys a little sound card too, but you make shure with this that he/she buys your soundcard (and pays you for that) and not other.

                                                    So, to sum up : less cables, less gear, easier to use and more profit for you.
