No Xtra.

a shot in the dark.
ive owned various studio rigs over the years from junk gear to big studio
products.
only times i got 'buzz' was incorrect grounding or a mistake.
sooo..

1..please explain how your rig is grounded.
by any chance do you have different bits of gear plugged into various different outlets ?? the net has loads of info re grounding.

2..assuming the same interface is used for all your music apps...if your not useing bb and say useing logic or other mac studio daw apps...
does the 'buzz' go away ?? is it only with bb ??
also it might be usefull to post a pic of your bb audio drivers set up.
bit depth/sampling rate etc etc.

happiness.
