One click fixes it — see the steps below.

What can I try?

  1. Click the reload button below — when the browser asks about MIDI devices, choose Allow.
  2. Click the lock or tune-fork icon next to the URL bar at the top of your browser, then allow MIDI devices for this site.
  3. After allowing, reload this page.
  4. If the browser never asks: the permission is saved as “Block”. Open your browser's MIDI settings (Chrome: chrome://settings/content/midiDevices), remove this site from the blocked list and reload.
