C14 - drum machine: snap to zero for samples

I’m starting to use more and more the drum machine, so getting the first questions [being used to sample track and Groove Agent]

When using a custom sample the start/end limits are automatically set on ‘snap to zero crossing’?

or need to activate it somewhere? Thanks!

someone told me that in a video on YouTube he’s pretty sure that there’s the function available, but obviously doesn’t remember which video and where’s the function lol

Anyone can give some hints? Thanks!
