The Traktorino is a powerful Arduino-based DIY DJ MIDI Controller.
The Traktorino is a MIDI class compliant device, designed for controlling Traktor. At its core, there’s a shield that connects to an Arduino Uno, which uses open-source code, making it totally hackable.
The Traktorino can also control any software that accepts MIDI, like Ableton Live, Serato, FL Studio, Logic, etc.
Details are currently sparse at the project site, but DIY kits and assembled options are planned.
