Yes, Ketron supports registrations. Might work a little different than you expect, might not. Think of it like this. Let's say you are going to play the tune "Laura." Select your setup and save as a registration called "Laura-1". Let's say the second time through you would like to switch from a Trumpet lead to a Tenor Sax lead. Go ahead and make that registration and save as "Laura-2". Make as many registrations as you need for that song and name them in whatever way makes sense to you. Do the same for how many ever songs you want and again name them, so you know which ones "go together" - up to a max of 4,096 registrations. The registrations are maintained across power-up cycles so once you create them they are there until you delete them.

Does that help?
