Hey Danny , thanks for your post and the article.
I’ve spent quite a bit of time reviewing this issue. The noise generated by ground loops with the OXI can be a bit annoying in certain setups (very big loops), but in most use cases is not a problem like it really is with other gear.
All the videos in Youtube where we are using modular gear, the OXI One is connected to a computer and the modular is being recorded by a soundcard and Ableton running on the same one.
In any case I aim to improve even more in the last hardware revision.
You can for sure use an external USB charger or USB power splitter to completely removing the humming.
