Benedikt Aufterbeck completed an apprenticeship as a pipe-organ-builder. His professional experience makes him able to do some tunings, solve technical problems and attach the technical equipment to the organ. His interest in modern musical technologies is one of the reasons why he is also developing a new pipe organ controller to be implemented in St. Peter and Paul’s church in Ratingen. In further run of this project he is about to create a MIDI console being able to imitate the haptic behaviour of historical organ manuals. This could be an ideal keyboard to mimic different organs’ key response behaviours.
