Due to the high cost of pipes and the quality of digitally produced organ sounds, pipe organ builders often offer digital stop additions for existing and new organ installations. Pipe organ companies do not build digital tone generation systems. Instead they rely on third-party suppliers for technology and circuitry.
Walker Technical Company is a supplier of digital stops to pipe organ companies. Recently, a Zimmer Organ console originally installed in 2006 that includes Walker Technical electronics was removed as the church prepares for its new Allen Organ. Photographs of the organ’s console and electronics are included below.
