Max MSP ( Cycling '74) controller

Hi everyone,

I saw a post on CasparCg fb page that shows a Max patch ( and touch osc) controlling CasparCG. I saw the part with udpsend, but I can’t get it work at all by sending any message to that. Does anyone know how to deal with it and is kind to explain? It would be very helpful to me :slight_smile: . All the best!
