Cool video, but that is NOT the DMdock. He is using the DMtouch app, but he is using it with a TMI and IOdock. His TMI looks to be a Simmons SD7K module (or similar) which is a Medeli module. You can see it under his second rack tom.
Maybe i'm "alesified" now
but i didn't take a look at the kit because i see the DMtouch app as a now completely separate product that doesn't need the DMdock. The dock needs an app (or a computer with drum software over MIDI out), that's the other side of the coin.
