System Update Downloads

To update, you must first download the necessary files to your computer (see below for the proper update), and load them onto a USB Memory Device (“Flash Drive”) initialized by your Sk Series (Including SKX), XK-1c or XK-5.

Please note! These updates will erase any saved preset data/settings in your Hammond and restore them to factory presets.
Consult the OWNER’S PLAYING GUIDE of your instrument
for information on how to store/save your personal settings.
