Controlling two laptops with Mixon 8

Hi all

This is supposed to be one of the features of the Mixon 8 but it doesn’t say anything in the manual about how to actually do it.

The only way I’ve found is by setting up one of the laptops in 4 deck mode and using channels 3 and 4 on that laptop, but this isn’t ideal as I don’t want to use 4 deck mode - I only want to see two decks on screen. Are there any other ways of doing this?

Thanks!
