How can I modify the range of the ObjectScale material node?

Hi!

I’m doing audio react with a sphere type and I want the material to glow when growing at scale 1.5 and turn off at 0.5.
I watched some tutorials and they use ObjectScale node where at 0 scale is dark and 1 scale is bright, it works for me, but not in the right way.

I have an object that starts at 0.5 scale and grows at 1.5 scale, how can I change the range of ObjectScale?

Have you tried?
