Had a reply from tech support by email, works with Cubase through using Mackie Control MCU adding a device and setting up through Cubase.
Might not be automatic but at least doable, they also say will add a script through next update so good news for Cubase producers.
Expression pedal supported so good news too. I'm surprised there aren't more manufacturers working to develop cool foot-based controllers for DAWs, not for live.
Best music producing to all.
