Where is Autofade?

I’ve got a couple of tutorials where I’m told to turn on “autofade” for a sample in instrument settings, but they are for versions prior to 3.0 and I can’t see it in 3.0… anyone point me in the right direction?

You can find it in the Sample Properties panel in the Sampler:

Look at “Playback” — Autofade is to the left of Autoseek.
