I just got the midmx 3.0 yesterday. I followed all the directions and not a single light is working. I watched all the painstaking videos. I tried calling customer support no-one picks up. I turned it on and off again,, tried different cables, installed and reinstalled I am using an iMac with the latest Catalina. The Hardware manager says it is there. PLEASE HELP!!!! The show is on Thurs.
