I think what he may be trying to say is he can sing better when the bass plays the root.
So a walking bass throws him off.

Just a guess as the translation seems a little rough.

If that indeed is the problem, then yes turn it down or off 'while you sing/record' the part.

For live performance it is trickier.
The bass walking down can be an important aspect to the song, so turning it down could diminish the effect.

At least that's my stab at it late in the day
