The result seems to me to be more like Reverb in my perception/use. Where the lower it is (like R= 0.5), the more restricted the space is so it bounces around more/intimate and the higher values are more like the room is expanding so its not as bouncy.
What does R refer to or what is it a spectrum from->to? What does the absence and abundance of resonance reify as observably?
A lot of times when learning about synthesis it can be more useful to have a visual guide as to what’s happening to your signal. Instead of a song have a look at this video. The first 5 minutes goes over what I’d gone over in my first post, and he goes on a bit about a few other things after that. Give it a look.
