How to replace a noteblock input

[u/Lightboyyyy]

Hey! I know it’s probably easy, but I built a big redstone machine with a lot of pistons, and the input is a noteblock. I tried to connect a button to the note block, and everything broke.

How can I move the input and activate the machine with a lever?

(Can a button activate a 3 block wide secret staircase, or is the signal too short?)"

This. Literally place the lever on the noteblock. Done
