Assign MIDI not working in Amplitube

I’m using Amplitube 5 in Cubase 11 Elements, connected to an Oxygen 61 MIDI keyboard controller. When I right click on amp or effects functions in Amplitube and choose ‘Assign MIDI’ and try to assign them to buttons or knobs on my MIDI controller, nothing happens and it just stays with the pop up ‘Waiting for MIDI input’. I had it working a few weeks ago but now it’s suddenly stopped. Any ideas how to fix it? Thanks.


Route a MIDI Track’s Output to this plug-in, please. Then use this MIDI Track as monitor track. Or better, use Quick Controls.
