Whether you’re interested in music, video or just flat out fun, this easy-to-build full USB MIDI controller is the open-source tool of your dreams. The minds over at Adafruit conceived this 16-button device based upon their Trellis button platform and an Atmel-based Arduino Leonardo (ATmega32u4).
The Mini OONTZ is a 16-button version of the much larger original OONTZ design. The miniscule controller features LED backlit buttons, a slick 3D-printed case, and even the ability to be connected to an iOS device for mobile play. If you’re looking for a place to start, Adafruit has a guide to building your own MIDI controller using an Arduino. The full tutorial, which can be found over on Adafruit, list of each the materials you will need in order to build your own Mini OONTZ MIDI controller:
- 1 4×4 Adafruit Trellis Monochrome Driver
- 1 Silicone Elastomer 4×4 button keypad
- 1 Arduino Leonardo
- 4 10k Potentiometers
As Adafruit notes, the potentiometer knobs can either be 3D-printed or purchased online.
With the ability to work with any MIDI software and hardware, the full-USB Mini OONTZ truly has unlimited potential because of its inherent hackability. Through the Arduino Leonardo, the device can be wired to power MIDI notes, LEDs and the potentiometers can control even aspects such as modulation. The group designed this kit for ease-of-use and ultimate flexibility, and it is hard to argue against those claims when looking at this highly accessible platform.
