This looks really promising.

It seems like an incredible device. It's like a drum machine, except you send midi to the device and it hits an actual drum. Super costly, at 1199 euros for the controller and three balls, and you can't even add more than three balls per controller. That's not enough to cover most pads on a conventional drumkit, though it might work well for drum and bass stuff.
I also wonder how this thing would manipulate a hi-hat, I don't think it would be able to.
Still, the tech looks incredible. I'm thinking if I run into a small fortune, I might think of getting a couple of controllers for myself.
I play drums myself, but I'm unable to play it with the guitar at the same time lol. This just might be really useful to me and I'm thinking some of you guys out there.
