Debby:

This is a copy/paste from BIAB 2021.
I assume you're looking for the bass to do the "walking".
Depending on the style, the walking bass may not be predominant but you can turn up the volume on that track.

Let us know if this is what you're looking for.
Otherwise, someone wiser here can likely help out.

Good luck!
