How to update the EP-40 Riddim firmware
The EP-40 (Riddim) updates its firmware over USB-C using the update utility on the teenage engineering website. You connect the device to a computer with a good quality USB-C cable, run the updater, and follow its on-screen instructions. This guide walks through what you need and how to make the connection.
What you need
Firmware updates run from a computer, with the EP-40 connected over its USB-C port. Before you start, gather the following.
- A USB-C cable that handles both power and data. The manual recommends a quality, USB-IF compliant cable rated for 5V at a minimum of 1A.
- A computer with internet access so the update utility can fetch the latest firmware.
- The EP-40 itself, ready to plug in via its USB port.
A poor quality USB-C cable is the most common cause of a flaky connection. The manual specifically calls out using a good cable for reliable USB-C power and data.
Connect and run the update utility
Once you have a suitable cable and a computer online, the process is short. The manual points you to the update utility on the teenage engineering website and lets that tool handle the rest.
