The Utopa Baroque Organ

The Utopa Baroque Organ has been developed by the Orgelpark. It was built in cooperation with four organ building companies: Elbertse Orgelmakers (Soest, NL) built the case, the wind work, the action and part of the wooden pipes; Hermann Eule Orgelbau (Bautzen, Germany) built the metal pipes and the other wooden pipes; Sinua (Düsseldorf, Germany) developed and built the hard- and software of the digital action; and Munetaka Yokota (Tokio, Japan) was responsible for the voicing. The Utopa Baroque Organ was inaugurated on March 21st, 2018.






The sound concept of the Utopa Baroque Organ is inspired by that of the Hildebrandt organ in Naumburg (Germany). Hildebrandt was a colleague and rival of Gottfried Silbermann, who built organs in Johann Sebastian Bach's time and region as well. The Orgelpark decided that Hildebrandt's less loud and more sophisticated soundworld would fit the Orgelpark hall best.


Old and new music

The Orgelpark needed a baroque organ in order to facilitate historically inspired performances of the music by Bach and contemporaries on the same level as the music by Max Reger c.s. (on the Orgelpark Sauer organ from 1922), César Franck c.s. (Verschueren organ, 2009), and older music (Van Straten organ, 2012).

At the same time the Orgelpark demanded that the new organ would inspire 21st century music as well. Therefore, it has been equipped with spring chests inspired by the chest built by Arp Schnitger and his master Berend Huss in Stade (1675). The tone drawers in these chests provide a pallet for every single pipe, and allow to operate thes with little computerized magnets. This means that the windflow from bellow to pipe remains uncompromised.

In order to play baroque music historically inspired, the Utopa Baroque Organ is equipped with a mechanical console (stop action electric, with a sequencer system). In order to be able to access the options the magnets offer, the organ has a seperate digital console as well. The Sauer organ is connected to this console also. You may find more information on how the console works and can be operated on this page.



The disposition of the Utopa Baroque Organ refers to that of the Hildebrandt organ at Hettstedt (1749; organ demolished in 1905, only the case survived). The facade is inspired by the Hettstedt organ as well, yet is proportioned in line with the comparable Hildebrandt organ at Sangerhausen (1728). Colours and ornaments are inspired by those of the Hildebrandt organ at Langhennersdorf (1721). The disposition is available here.


User Manual Digital Console: playing the keyboards

On the digital console any stop of the Utopa Baroque Organ (and, to some extend, of the Sauer organ) can be chosen on any manual (or the pedal). Stops can be transposed easily. The basic principle is that every manual can have more than just one registration; the number of registrations is virtually unlimited. 

In order to show organists how to use the digital console, the Orgelpark developed a User Manual, available here

We also made movie to introduce you to the console:

User Manual Digital Console: playing the organ using MIDI/OSC

In order to show musicians/artistis who like to play the digital console by using laptops and other control devices, the Orgelpark assigned composer Wouter Snoei to develop a user manual, which is available here.

The development of the concept of the Utopa Baroque Organ is documented in Orgelpark Research Report #5/1. Orgelpark Research Report #5/2 documents the complete building process and discusses aspects such as the temperament, as well as the life and work of Zacharias Hildebrandt.
