Yes, it comes with many different midi patterns that you can use. It handles it quite strangely though. Instead of dragging and dropping the midi pattern out, it handles all of that within BB. There is a huge downside to this, because you would be limited on which patterns you would want to use.
What I do, most all of the time, is find a midi pattern that I like. Play it a few times and build the midi pattern within my DAW. That way, no matter what, I have the pattern.
