With the knobs, I just figured out the problem was a stray div from an earlier version of the app overlapping the knobs in the components section of the demo app. I've fixed that now. Checked in both desktop and android Chrome and looks ok. haven't tested in mobile safari yet.

P.S: I agree knob controls in general are terrible UX. A real knob is usually turned with two fingers and the way on-screen knobs are operated is nothing like that.
