Midi Foot Controler

I was recently watching a video of Ed Sheeran on stage stomping on his custom Chewie II pedal board. I learned that it communicates with a midi controller in his case. I realized, wow, it would be awesome if like you see him or other musicians that do looping or have foot pedals that I would really like to be able to use foot pedals to control Wirecast while doing live 1-operator-show broadcasts. Nobody ever sees my feet anyway and the boards would be easy to memorize and tap without looking away from the camera or anyone really noticing.

I attached a sample image of something like what I had in mind.

I found some videos about Wirecast 8.2 that explained the Midi technical preview feature. I thought, cool, must have those custom mappings by now! I'm on 12.0.0. I logged into to check and was disappointed. It only supports a few boards and not what I have in mind.

I also found some fairly convoluted options using multiple levels of software

midi controller -> midipipe -> another piece translating from midipipe to wirecast -> wirecast...  

phew... don't really want to do that when it's clear that Wirecast is now technically capable of accepting a wide variety of midi inputs and producing appropriate output since version 8.2 at least.

Any updates, links, Wirecast 12 APIs, thoughts or information on custom midi controller mappings would be appreciated so I can continue this exploration and rock my single operator shows AND keep my focus on the camera.

Thank you.
