Only the routing to it, and the input channel settings (you're coming into.)
If your external fx are digital, most offer a way to store presets. If not, grab a pencil and make notes if it's really important, or create a Word doc and type them in.
When we NAME the song ==== plenty of room to make notes -- we have external racks --- and use maybe 10 presets ...if we vary a delay }} we place a reference on the NAME section..
