My band just got a Behringer x32 rack. One of the cool features is that it appears to have an app that can be used to wirelessly control it. I've been trying to understand the manual regarding getting the internet set up to use it...does it need to have some sort of continuous connection to the internet to be able to use wireless control? Or does it just need to be connected to the internet once and then could be moved to a different venue and still have devices connected to it? Thank you for any help you can give!
