Audio input set up

I am running cubase pro 9.5 on a iMac. I have connected a motu 828 mk3 via FireWire / thunderbolt with adapters. I have connected 8 analog ins to the 828. I have created an empty cubase project and selected 8 audio tracks. From here I don’t know how to configure so that analog 1 can be recorded to audio track 1 . I’ve tried lots of variations but nothing seems to work. Can you tell me exactly how to configure this set up? Thanks Mark

It is explained exactly in the Cubase Manuals: You connect the Cubase busses with your hardware´s device ports in the VST Connections, then select the correct bus for the track you want to tecord to.
