Initial sketch for a final design

This sketch shows off my current idea. Using the motor controllers to entirely control the strings, with parts on the string to change the pitch. Another idea I had was to have a bass section, using pedals to control them, like organ. For now, I’m not sure if the bass section should stay, as it will add another section and part to create. But I know the top section, with the controllers and buttons, will stay, and that is my idea.

I need to attempt to create something similar and smaller, maybe with 3 strings as a proof of concept.
