There's a piano in the classroom. With a MIDI keyboard, you play on it and the other person sees right away which keys you press.
What you need
A MIDI keyboard with a USB cable or MIDI adapter

The keyboard isn't detected?
Step 1: In the classroom, click Settings at the bottom left.
Step 2: Open the Midi tab. Under Midi Input, you see whether your keyboard was detected.
