I need one of these, because the USB to MIDI device that I have (M-Audio Uno) sucks. I'm on my second one, and it likes to lose it's connection every 10 minutes.

I know I can nab a cheap(ish) interface for a couple hundred, but all I really need is a FW800 on one side, MIDI in/out on the other. This is for my Mac Mini, which sits on top of my rack and controls my Ultra.
