As announced here, Apex Fusion now has support for the added two color channels (warm white and violet) in the Radion Gen4 Pro fixtures.

AOS version 5.00_AC16 has the necessary Gen4 Pro support; if you have not already updated your Apex (2016) to 5.00_AC16 or a newer AOS version, you will need to do so. A video is available to guide you through the AOS update.

The final part of enabling Radion Gen4 Pro support is updating the WXM. This Neptune Systems has just posted a YouTube video showing how to do that. Please be sure that your Apex (2016) is running AOS 5.00_AC16 (or later) before doing the WXM updates.
