Description

The 8mu is a pocket-sized MIDI controller (slightly smaller than a credit card!) with eight faders that can send messages via MIDI. The 8mu also has a built in accelerometer which measures how the device is being held. This creates eight more control signals, mapped to gestures like “lift the front” or “turn me over”. There are four tiny buttons along the top edge, which can be configured to send MIDI notes (like a keyboard) or control signals.

MIDI data is sent via a 3.5mm TRS MIDI output, which can be Type A or Type B, and via USB-C. Only standard USB data lines are used, so it should work on any USB computer with an adaptor. The device is also powered via USB. 8mu can store 8 banks of CC settings which can be accessed using the left and right buttons on each side of the device.

8mu has a web editor where you can edit all the settings: Launch the 8mu Editor, and there is a quickstart guide printed on the back or here’s a quickstart PDF

The 8mu design was inspired by the 16n project but the hardware is quite different. The editor is a modified version of the 16n editor by Tom Armitage. 8mu cannot send i2c or CV, but it’s designed to be open and hackable and can be re-programmed in Arduino or Circuit Python code.

Radio Remote

8mu can be used as a remote for the Music Thing Radio Music MK2, all kits purchased from September 2026 onwards include a Radio Remote alternative panel.

Radio Remote gives tactile, playable access to many of the settings of the Radio Music MK2 module. This allows for quick performance of parameters such as Speed and Loop mode without having to edit any settings on the sd card file. The remote connects to the radio Music via the USB socket on the module frontpanel.

Note: other midi controllers will not work with Radio Music, but if you already have an 8mu, you can update the firmware to use it with Radio Music MK2 and get the remote panel HERE

Radio remote connects via USB-C, we don’t include a cable inside the kits as we believe there are already enough USB cables in the world.

Radio remote only works with the new 2026 version of Radio Music – it does not work with Radio Music V1.
