I don't think this is a problem but I thought i'd check....
In my setup i've got 48 channels of LOR as number 1, followed by 50 universes using Multicast. Due to a new mega tree, I've added 8 universes using unicast (E682 controller). If this will work it would save me time seting up the controllers that utilize multicast. If not I'd have to change all the controllers to Unicast.
Additionally, I use FPP to run the show... any issues with the mixed multicast and unicast setup?
