Here's a noob question about spreads and Change

vvvv beta question
#1

I want a singlesliced Bang (or whatever) when there’s a change in any of a spread’s values. How? I mean, + (Value Spectral) kindof does the job, but is there something else maybe?

#2

Take a look at OR (Boolean Spectral) (near the end of the video).

#3

ah, perfect. Thanks!
