Extracts from the builder's leaflet, written by Hans Gerd Klais:

"This organ was designed as a teaching instrument, and, as such, despite the small number of stops, has three manuals, and in spite of the small available space is clearly and logically designed to be accessible, even inside, to explain to organ students the technical aspects of the instrument.

The Hauptwerk is planned to provide a pleno manual... based on a substantial Gedackt 8'.

The Positiv, enclosed in a swell box, constitutes a cornet in separate voices. In power it is equal to the Hauptwerk.

The third manual contains only solo stops, one of which is a Klarinette with a free reed, and the other a Dolkan which performs the function, in this small room, of a large-scaled flute.

The stoplist was drawn up by Prof. Teruhisa Fujieda of the Musashino Academia Musicae.
