Every truly legendary party needs an in-house DJ, but transporting all that equipment and setting it up, or even just learning how to use it properly can be a major hurdle. Tuna Knobs combines the accessible, portable world of digital applications on touch-screen devices like tablets with the tactile, precise knobs of a physical device. These knobs can be affixed to a screen and twisted like the real thing to offer a more realistic feel. Tuna Knobs will be a great pickup for the casual music enthusiast, but those who are serious will scoff at this stopgap in lieu of a real deck. Tuna Knobs are €9 and launch in November.
