Here is my first attempt: https://youtu.be/u4RSlO9nS50

Bear with me, video is not my medium. I used my photo camera with a tripod and a light I had around. To avoid the need of cutting I just used the microphones built into the camera, which I agree is suboptimal. But I hope you get the idea. The video demonstrates both the key assignments and how I use them for the music. I didn't play for a few weeks, so I'm a bit out of practice, but it's all live and improvised.

If you wonder what I wear: these are padded socks, three layers, to avoid hematomas.
