%~ fft~?!?!

I stumbled on this by accident and am a bit embarassed to be bringing
it up to the list. Both of the patches are pfft~:

Does this:

sound better (clearer, less distorted sound, with more flexibility) that this:

I've been trying to wrap my head around it for a bit now. The math
overlaps a little, but not enough to make any sense to me. Any
explanations (or disagreements in the sound quality) would be great.
If this is common knowledge, then I'll gladly go whip myself. I
especially had fun playing with the volumes before they went into the
first pfft~.

HUH?,
