Logic Pro X - Piano Roll Grid

How the fucking fuck do I change the grid size in Logic Pro X?

I recently bought it but haven't had any time to actually fool around with it. I feel like a complete idiot using it. I've used Logic for 12 years and now I feel like the worst n00b.

How do I change the grid from being 1/16 to 1/32 or to 1/64?

In the transport. Might not be visible if you've customized it.

On the left side of the transport, you'll see there's either a music note, a clock, or a gear. If you click on that to change it to custom, you'll see that option pop up.

I think the UI designers hate musicians.
