Thank you all,
I have partially solved this. Enough to my satisfaction, by lateral thinking. Using a minijack to minijack cable I can input the sound from the laptop's minijack to my Nord Stage 4, via the female minijack "monitor" input of the Nord. Worked immediately.

This is great, as I no longer need to think of long additional cables for the laptop and can have my laptop right on top of my Nord, for full control.

I can see no way of using Asio with Band in a Box, without buying a further interface for gigs. I don't want to dismantle my Focusrite 18i20 from my home studio PC setup. I shall therefore simply give up on this.

I shall use Cubase for recording

Thank you all
