Weird cutoff issue

[Nsemest182]

For every preset.. When I turn the cutoff knob all the way down I still hear a very faint saw wave at full bandwidth (or whatever waves are chosen) OR it only affects layer A and not B. I tried calibrating but that didn't solve the issue. Something isn't right here..

I’m confused by the phrasing here. Are you turning down the filter on layer A but not layer B? It shouldn’t change the filter on both unless you have the “edit layer B” button flashing (achieved by holding it in for a short second).  Other than that, do you possibly have audio mod turned up on said preset. This doesn’t happen on my prophet (that I’ve observed) unless it’s so quiet that it’s negligible.
