Loopback hardware or software

This probably has been discussed previously, I’m trying to get my dmx lights controlled by a midi track. I purchased an Enntec open usb box only to find out the Dmxis vst doesn’t work with it, so I have been learning something about QLC+. It seems there are different options to get the midi information to QLC+, a midi loopback program is one, I also see Cantabile has a loopback ports function. Another possibility I’m thinking is since my midi interface is 2x2 maybe I could just connect one output to one input.

Any thoughts?

Thanks Doug
