What does the SR meaning in Halion/Cubase?

I find many pathes in Halion having SR prefix. And some of the reverb preset have the SR as well?

What does it mean? Surround? Do the SR meaning the same?

I believe it stands for Sonic Reality.

That is a pitty. There is no official response.

I’m sorry my response wasn’t “official” enough for you.

LOL

I’m 99% sure that they are simply patches created by Sonic Reality …

Good luck with waiting for an “official” response on these primarily user to user forums unless you are talking about Dorico, WaveLab, or SpectraLayers. Developer interaction with those three is absolutely amazing.
