Questions
Common questions
Which computer keys play which notes?
The A to K row plays the white keys and W, E, T, Y and U play the black ones. Z and X shift the octave down and up.
Is the sound a recording?
No. Every note is synthesised in your browser from scratch, which is why the page loads quickly and works offline.
Can I use a real MIDI keyboard?
Yes. Plug it in over USB and allow MIDI access when your browser asks.
