Both hands on a piano, in real time
Jev sees the note waterfall and controls ten fingers.

@typesafeai's Jev controls the 2 hands and each finger to play the piano in real-time. Jev only "sees" what we see and plays this from the "note waterfall". It uses @browser_use's jev-ultrafast and some decision scheduling to make this happen in real-time. Sound on 🔈🔉🔊

Chandramouly Kandachar has Jev control two hands and every finger to play piano in real time. Jev only sees what a player sees, the falling notes, and the build uses the jev-ultrafast setup from Browser Use plus some decision scheduling to keep up.
