# Why Can't I Connect My MCX to the Web Editor?

In order to connect and use the MCX you must be using the Google Chrome browser (version 80 or above) on a Mac, Windows, or Android device.

We use the Serial API to communicate with the MCX, since this is brand new technology, you must first engage the <span style="text-decoration: underline;">**Experimental Web Features**</span> flag within your browser. Paste this link into your URL and enable the flag, [ chrome://flags/#enable-experimental-web-platform-features](https://docs.jetpedals.com/%20chrome:/flags/#enable-experimental-web-platform-features " chrome://flags/#enable-experimental-web-platform-features") once you restart the browser you should be able to connect and program the MCX.
