Hi All, I need some help. I just bought a 2013 Mac Pro. It has only USB 3.0 ports. I also just bought a M-Audio Midisport 4x4 midi interface (I finally pulled from my boxes some old sound modules and a synth box that have been sitting there for a few years). After two days of tweaking, I found a little knowledge base note from M-Audio that none of its midi interfaces work with USB 3.0. There solution: get a USB 2.0 port (thanks). Anyway, does anyone know of any midi interfaces that work with USB 3? I also only need 4x4 ports (not planning to buy any more hardware midi devices). Thanks!
