Give sites permission to MIDI devices in Chrome

You can connect a site to your Musical Instrument Digital Interface (MIDI) devices in Chrome. MIDI is a standard way for electronic musical instruments, hardware, and computers to communicate. You can control virtual synthesizers, drum machines, or other instruments with your MIDI keyboard or controller.

Only give device access to a trusted site. If you’re on a site that’s connected to your MIDI device, the site may access and change information on the device, including possible firmware updates. The site can send and receive MIDI messages to and from your devices. This allows your device to make sounds and the site can access the notes you’re playing.

You can protect your information when you visit sites on your computer or Android device when you choose your permission settings.
