How to update the Eventide H90 Harmonizer

Install H90 Control (download it from your Eventide account, where you also register the H90) and run the installer. Power on the H90 and connect it to your computer with the supplied USB-C to USB-A cable. Open H90 Control, click "Add Device" in the top right corner and select "H90 Pedal". If the computer is online and a newer version is available, H90 Control prompts you to update (cloud icon): follow the on-screen instructions. Do not unplug the H90's power supply during the update; the screen shows a connection icon while it runs.
