Blogger Omunchkin13 posted a video on Reddit showing him playing through Elden Ring with a piano as a controller.
At the same time, the piano continues to play the melody (albeit out of place), but the overall picture still looks very impressive.
Omunchkin13 used software called Bome MIDI Translator to remap input from a computer keyboard to an electric piano.
However, he only downloaded the free version, so he had to reconnect every 20 minutes.
The action game also received a content update.
