No MIDI in Standalone... DAW works fine

I just purchased several plugins (Cory Wong, Morello and Morgan) and have two midi controllers (Helix and Arturia Keylab) that both work in my DAW (Cubase) but not in standalone. Both controllers show up in Settings and I can select them. But MIDI learn does not work, nor mapping the controller manually (CC Absolute, etc…). However it works fine through Cubase when I create a MIDI track for the controller and side chain into the Neural plugin. What am I missing in standalone?

Thanks!
