Hi there, I was playing around and found that distortion adds a bit of buzzy noise when processing very quiet sounds. It’s actually kind of cool, but I thought I ought to point it out. It looks a bit like logarithmic bit crushing or something… I figured it might have something to do with jumping between integer and floating point audio. though what do I know haha 
edit: I should say that it’s only found on the “razor” setting, so it should be an easy fix.
also: Windows 7 x86, if that’s important
I made a doofer chain that should make it simple to reproduce; it’s attached below.
