A more open-ended usage:

Let's say the user has in his head some pretty defined idea for the beat pattern for their project. So, rather than having to do a lot of manual search through the loads of RD's already on offer to find a perfect/decent match, they could make a brute couple of bars in midi (with the help of the Piano Roll or something) and submit to this proposed Pattern Detector that then did this search for them much faster.

Just because you can, doesn't mean you should!
