Dennis Chambers, Horacio "El Negro" Hernandez and Ultimate Drum Camp (UDC) have designed this new application to give all the world of musicians access to a polyrhythmic metronome that is innovative and that the world has never seen before. Our goal with this app. was to open the eyes of all musicians (not just drummers) to extremely complex time over time polyrhythms. It does every possible polyrhythm a human can do with 4 limbs!!
