It's Butterrr with three R's

For someone who absolutely loves music, this is a very amusing piece to play with, mostly because you are in control of what kind of music it is exactly that you produce.

A tip for those who will try it: If you like what you hear, then make sure to take a print screen of the pattern that you create, so that you can use it as reference if you want to listen to that particular tune again. 

Oh I absolutely love it!
