Is it possible?
No, Cubase doesn’t support Audio Units and the plugin is integrated into Logic, so no other DAW can use it.
Using it in Cubase will only be possible if you use the old version made by Camel Audio.
You can buy MainStage, and play it in “live”.
How would this work?
There’s a lot of info on the web. Check out some of these. Talks about Ableton, but principle is the same.
