Every gaming lifestyle brand has a stream-control device in its lineup these days, but none even functionally close to the MasterHub by Cooler Master. This is a modular, highly customizable stream control panel, in which you can swap out modules to alter its layout and functionality. A base plate roughly the size of a 7-inch tablet has various contact points on top; you pick and choose the modules you need, and mount them on top of this dock.

Among the modules available are everything from a 15-key Lebdev pad, to one with a 5-pole fader, to one with rotary knobs, to another with drum rollers, to another with a puck-shaped touchscreen. You can mix and match them as you need, and everything is programmable using the MasterHub app. You can even have multiple modules of the same kind—think two Lebdev pads worth 30 keys; or as many MasterHubs as you want. The base plate aggregates all modules into a single USB-C connection to your PC.
