The drehbank ( http://www.doepfer.com/db_e.htm ) is a MIDI controller, pretty much like the Phat Boy, but with more buttons, all assignable, and also CV compatible (analog communication protocol).

you can use it with REASON, REBIRTH, most VST synths, but i am not sure about the d-lusion programs (drumstation...)

Read the page there, there are many info about it... hey this is some PRO gear right there. Doepfer is no joke.
