It looks pretty good on Pd vanilla, too.

But that's how you did it? The code in your patch is based on the code
from vslider_bang? I don't understand it at all, but it works :-)

And you're asking, why go all through the trouble to get back the input
value instead of just spitting out the input value? Not a clue (someone
wanted to show off their math skills?)

"Hehe, look, I can do it this way, but look now, I can also do it this
way .. hehe .. pretty cool, uuh?" ;-)
