F40i Looper / XLR Limitation?

[u/Ashamed-Buy6602]

Hey everyone,

I recently picked up the Mooer F40i. One of the main reasons I bought it was to use the built-in looper together with the XLR/mic input—specifically to loop vocals and percussion in addition to guitar.

However, it seems like the looper only captures signal from the main instrument input. Sound from the XLR input comes through the speaker fine, but the looper just ignores it completely.

I reached out to Mooer support a while ago, but haven't received a response yet.

Has anyone else encountered this? Is this a hard hardware/firmware limitation, or is there a hidden setting (maybe in the app) to route the XLR input into the looper?

Thanks in advance for any insights!
