Recording GA4 in Cubase 8

I think there MUST be a simple way to record GA4 audio into Cubase 8 but I’m finding nothing about it in the manual nor in the online tutorials… so far. This forum hasn’t addressed that question as yet but I’m still hopeful. It must be such a simple thing to do. I find the manual too vague and the tutorials very impressive and somewhat helpful but too fast and assuming of a top technical engineering expertise. Where is the step by step guide for the professional musician that struggles a little with the initial learning curve? I only need a little kick start and I’ll be away. I wish I could trial the Songwriter’s patterns before I have to commit to buying… that is my primary reason for trying GA4.
