Man, this is great! I will get hours of use out of this guy, for sure!
I think that as good as the core application is itself, and as much fun as it is to play with, the real genius of this application is how you incorporate the history of the drum machine, and how it has been put into use over the course of more than a century. I learned something from you, today :]
