Assigning Behringer BCF to only Midi data - Cubase 13

Hi all,

For some reason, my trusty Behringer BCF unit, which I’ve always assigned to control midi data, has started to control audio output track volume as well.

The way I’ve always had it set up is that the first fader controls CC number 7, fader 2 expression etc…

The way this always functioned was that whatever midi track I was on was being affected and only that track was being affected.

Recently, for some reason the Behringer is starting to affect the overall volume of my group tracks, and I’m not sure why this is happening. That is, even though only a midi track is selected and I’m trying to move the first fader to control cc7, on that track only, the first group track also moves.

This is really frustrating as I can no longer use the behringer the way I normally have. I’m sure this is some sort of user error on my part, but I’m trying to figure out how to solve it quickly.

Thanks for all your help
