I found the author of the YouTube video in my previous post.

He is Frank from Germany.

He has written a User Guide on how to configure the Yamaha MC10 Foot Controller with the GENOS.

https://www.keyboard-akademie.de/wp-content/uploads/GENOS-und_MFC10_V2.pdf

Frank included a Table on Page-18 that shows the Control Changes and Notes to trigger the Style Elements on a GENOS.

The best part is that you are not limited to the Yamaha MFC10.

This MIDI Implementation on the GENOS allows any External MIDI device to work so long it can transmit a Control Change message and a Note message.

This is brilliant!

I found the thread on PSR Tutorial discussing this very issue in details:
