That wasn’t it for some reason. I maxed out cut on the mix screen, got some worms wriggling, then went back to the mix screen and there wasn’t any activity in the cut fader, and when I turned the input down it was definitely silent.
I’ll keep poking around, but if you think of anything else, I’ll try it. Thanks!
Edit: I found it, I hadn’t checked the softcut settings in parameters, everything was turned down to -inf.
Thanks for the help though, definitely sent me in the right direction!
