Hi Maurice depends what you are trying to do. if your BIAB songs are already complete and you want to add vocals or live instruments the obvious way to do simple recording is to open the song in RealBand which is certainly goood enough for lots of us as a DAW. On the other hand if you want a hardware solution, export your BIAB track as a wav fileto a multitrack recorder.

i'm not a cubase user so don't really know but if your needs ae reasonably simple I would have thought RealBand will be fine - lots of us do use it and don't need anyhting more.

I'm also in the UK so if you want to talk send me a PM
