Bitbox micro introducing noise when midi in connected

[jpablo91]

I noticed that the bitbox Micro introduces some noise when the midi in is connected. I think this is an issue from the new firmware (version 2.2.3), here is a short video that shows the problem: https://youtube.com/shorts/cOeRpv0isy4?feature=share
I was wondering if this is a known issue, or something regarding my setup.

Is this still present for you? Any particular MIDI in source?

The MIDI source will be relevant here. I also see some ground loop/noise issues with certain combinations of devices, depending on the power source and load. Can you provide more details?

This was solved by using one of those ground loop isolators. Not sure where was the noise coming from, but now it’s fixed. Thanks!
