Hello @Matthew_Cole,
Are you using the Chord ASIO driver or the Windows 10 WASAPI driver? The Chord Mojo has previous known issues with the Windows 10 WASAPI driver, I would try using the Chord ASIO driver instead. You can find a link to the driver here

You may also be able to resolve this issue by disabling “Event Driven Mode” in the “Show Advanced” menu of “Device Setup” for the Chord Mojo zone.
