Reply to Can one convert a USB arcade pad to MIDI controller?

I watched Ean's DIY video on the DJ 101, and I was very intrigued by the idea of creating my own arcade controller on the cheap. However, I was considering purchasing a USB Arcade controller, and I was wondering if I could use that as a MIDI controller with Traktor Pro?

As you can see, it has 8 arcade buttons, and a joystick (I was hoping to be able to use this as and expression controller, but I really have no idea how to do that, suggestions?) and its output is USB.

Any Suggestions?
