Turn on a switch from the note box?

I'm trying to turn a switch on from a State's Note Box, how would I go about doing that?

I'm using VX.

What I really want is a switch to be on when I have a state applied to a character, and when the state is removed, the switch turns off.

Why not use a conditional branch? or a few conditional branches really to check each party member?

Yeah, I was planning on doing that through a common event set at Parallel. But all of them caused some massive lag. The way my battle system is working, all I want states for are to make things difficult on the map and not actually in battle. So I want to have it so that when a state is applied it will turn a switch on, which will trigger a common event that will mess with the map and controls and stuff. I was looking at your note editor Modern, but I didn't see that you could do that with it.
