Try Rightclicking on the Piano part and selecting MUTE.

The Piano trackname should turn RED, indicating it is muted.

Then Render your files.

The MUTE of the track should stay put for the entire session but will revert back to being played the next time you open BB, so if you want to continue Rendering that way you simply repeat the above on any new sessions.

BTW it looks as if the new UPDATE, released today, may have fixed the problem, always worth keeping track of the program updates, download and install them.
