Getting started with GridPie

Is there a good guide to getting started with GridPie, or some example XNRS to try?

I’m curious how people work with it, organize chord changes, and so on.

Do you mean, the Duplex variety? GP also exist as a smaller, more basic standalone version.

When asking the question I was thinking more of general practices that I would guess could be used with either, but specifically I’ve been trying to use the Duplex GridPie with a Launchpad clone.
