Last week I received my Midifighter from DJ TechTools. What's a Midifighter you ask ?
A midifighter is a midi controller made up of 16 arcade buttons (slightly smaller than your standard arcade ones) on a light frame that connects to your PC or Mac via USB. This controller talks to your DJ software, in this case, Traktor Pro -- and with the aid of different mappings you can create something out of nothing.
Check out this demo video I did using the Deckalized mapping and below is the Instant Gratification mapping.
