Make Noise Function is more attractive to me than the SSF Mini Slew.

I guess if you know well how it works maths, and you need more or less the same in less hp... function is a natural choice.
I'm still learning Function, I don't know all its possibilities, but I discover a few of them, and it's amazing. Maybe in future I'll switch to maths, but in this moment function seems ok to me (in less hp).
