This may seem like a vague issue but every now and then my FX units resets to INSERT when I mess around with the new filter FX. As a result my FX (delay) cuts off when I close the line or cross fader. Maybe this is related to the crossfader not being POST FADER for the filter FX. Someone at NI told me this was a design choice but it doesn't make sense to me. I have made a workaround in my mapping by setting FX Unit -> routing selector to POST FADER when I press any of the 4 FX buttons on my Z2 but I hope you can fix this.
