Elden Ring player defeats Margit by using an actual, real-life harp as a controller

A musical Elden Ring fan has discovered how to turn their harp into a fully-fledged controller, and gone on to defeat Margit using the instrument-turned-gamepad.

Harpist and Elden Ring player u/Lettuce4Dayz shared their achievement in a brief video(opens in new tab) on Reddit, showing themselves attacking, rolling, and controlling their in-game character by plucking specific strings of their harp. They’re able to defeat Margit, the Fell Omen by simply playing the instrument, with no traditional controllers involved at all.

Explaining the process in a comment, the harpist says they used two computer programs to transform their instrument into a gamepad. One detects the pitch of whatever note is played on their harp and converts it to MIDI, while the second binds each MIDI sound to a specific keystroke.

“So for movement, I have a string that makes me move forward, one for backward, one for left, and one for right,” they explain. “Each time I pluck one of those, it cancels the other out so that I don't get stuck trying to move two directions at once.”

“My character continues walking until I play a completely different string, which cancels all of them. I also have 4 strings that control camera movement in small increments. Because of that, it's difficult to make sharp turns and do 180s which is why I fight locked on.”

Roll is bound to a high A note, and Light Attack to G. Lower strings, meanwhile, are reserved for movement and secondary actions, such as healing. u/Lettuce4Dayz says they weren’t able to find a note for Heavy Attack, because all available (reachable) strings had been bound to more essential actions. 

Similarly, they can’t spring nor control the direction that their character rolls in, since movement and dodging are
