Working like a stylus, the Tuna Tablet DJ Knobs can be considered as physical controls knobs for your touchscreen. They come from Tuna DJ gear who are a Kickstarter funded, Rotterdam based startup. These knobs can work on iPad, iPhone, Android and Windows tablets. All of them are even compatible with a number of music and DJ apps. So you can now set up your DJ themed tracks anytime anywhere without losing out on the tactile side of DJ’ing with these knobs. What track will be up on your playlist first?
