Rotating control stick quickly on mac?

[hoshinokirbys]

Ok, first, this thread was the only help i could find. And the suggestions didn't help at all. I have tried:

• Setting the directional keys to 7, 8, 9 ,0 so i could swipe across
• Using Keyboard Maestro to create a shortcut
  

I know this will be required later for tube mode, but i have no controller. Is it more worth it to invest in a controller than to try to solve it otherwise? What kind should i even get?
I have a save state loaded in the super hammer tutorial. It is the farthest i've gotten
