I'm trying to use a Launchpad mini as a MIDI controller for MyDMX 2.1. When I right click on a scene I see the options to make Keyboard and MIDI shortcuts but I can't click on Create MIDI shortcut because it is grayed out. The option to create a keyboard shortcut is there and it works but not MIDI. I've only previously used this Launchpad mini with Ableton to make music on this same laptop, so I know the drivers are installed. I'm using a 2013 Macbook Pro with High Sierra. I tried checking for updates but I don't see any for the software. Am I missing something that needs to be done to get MIDI working with this Launchpad mini?
