Hi,

Upon request from an inMusic consultant, I am sharing with you the problem I have encountered with my Numark controller in order to make the product developers aware about this issue.

I was using the latest version of the firmware : Engine OS 2.2.2 and I could not activate the Lighting System. It did not appear in the Services menu of Settings.

The inMusic advisor ask me to revert back to firmware version 2.1.1 and there I should see the option listed in the Services setting menu so I can then enable the Engine Lighting (He gave me the USB Updater to the Firmware 2.1.1). And it works !

​Once done I revert back to Firmware version 2.2.2 and I still be able to get into the Engine Lighting preferences.

Problem solved, thanks
