ok, one more thing...

So Spring from SuperCollider is just a very simplified model, and according
to people in the SuperCollider forum it's not really different than a 2nd
order filter like Ringz or resonant~ from ELSE, right?

So I'm failing to see where SuperCollider's Spring shines. I already ported
it to a compiled Pd object, and I also ported the MAX code but I can't see
why I should bother including them or what would be special about them. I
like the Ball object from SC and that seems like something fun to have...

But then, I think I mentioned this before, I came across Spring in SC here
on this code on Scanned Synthesis https://sccode.org/1-4Rm it's just a
chain of Spring objects connected in a series, with a feedback loop, so
it's circular. The output of each spring is an audio channel output and an
object crossfades between the channels and "scans" it.

So now I wonder if Spring is indispensable in this patch, and if one can
just use some other 2nd order filter instead. I am also presuming that
there might be some technical details where the sheer simplicity of this
setup misses some important factors that you are covering in your scannd
synthesis implementations with pmpd, huh?
