The Grand organ consists of 37 stops and 44 ranks of pipes, for a total of 2,478 pipes, divided between three manuals and the pedal. The traditional layout of the organ is in the strict order of the Werkprinzip. The pipes of the Hauptwerk division are in the center of the organ case. Below the Hauptwerk is the Schwellwerk. The pipes of the Schwellwerk division are located in the lower case behind the expression shades, which allow the organist to control the dynamics of the sound. The divided Pedal division pipes are cantilevered to the left and to the right of the Hauptwerk. The Kronenwerk is located above the Hauptwerk.
The stop action is electric, with a computerized multi~level combination action, allowing for easy and rapid changes of registration. No other electrical or electronic devices are employed, with the exception of the blower motor for wind supply. The Grand organ can also be registered and played from the Choir organ manual and pedal key boards.
The Grand organ was constructed in our shop from May 1997 through February 1998. It was disassembled and transported to Mount Angel for final assembly. The instrument was completed in June 1998.
