(see attached image) This is an issue I've encountered in a couple of projects now; the basic function I'm trying to create is a means of detecting when an envelope is not being used. so a Compare/Equal module will simply read out 1 whenever the Envelope is at 0. Simplest thing in the world except that, uh, it's..... not? Doing that? Honestly what am I missing here? Am I even missing something? Have I just broken physics? What do I have to do to repair the laws of mathematics?
