Hi Compu Cue Basics never had 4 universes available at all, it is a single universe interface, it may have allowed the same single universe through artnet, but that's it. Same for the Compu Cue interface for two universes. If you need 4 universes that is the SDE interface. but you can stack interfaces, so 2x Compu cue's could get you 4 universes and 4 mirrored artnet universes, ah OR, pick up a MyDMX Buddy and upgrade the license to Compu show and add an artnet license, that should be under 450.
I haven't been able get anyone in the office with access to a Cue to test, short staffed due to the COVID situation.
