The first of my giveaways is when someone uses one of the "stock" styles and just hits the button. That generates figures that, if you are familiar with the BB styles enough, you've heard a few gazillion times before.
There are ways to avoid that, such as simply regenerating a few times using the Replay button until you get something a bit different, or as many do, exporting to DAW and slicing and dicing to make what is called a Compilation Track.
Compilation is used with live players in the studio, as well, editing several takes into one take, or moving a nice phrase from one place to several or many places, perhaps to use as a hook, things like that are fairly oommon.
So why not treat the BB generated tracks in the same fashion?
