Build­er is a line of DIY parts that make it easy for users to design their own USB MIDI con­trol sur­faces and devices using but­tons, knobs, faders, and talk­back LEDs. The BYOB (build your own board) series allows you to eas­ily con­fig­ure and cre­ate a con­trol device with mod­u­lar, per­for­ated cir­cuit boards that can be organ­ized into cus­tom­ized setups and configurations.
