Hey why is it grayed out when I try to select it for my effects rack. Even after I made all other slots unassigned. 🤷🏻♂️
Did your show file happen to come from a ProX? One possible way this can occur is if the original show file had the Midas Spectrum Analyser loaded on an Effects slot past slot 6 (since a Pro2 only has the capability of 6, all the other FX won't load -- also due to the nature of the MSA, you can only load one instance.)
Try closing the Show, opening a new one temporarily, and see if you can load the analyser again. If so, you know it's something with that particular Show File.
