Luedingworth Organ

Lüdingworth, Arp Schnitger Organ (1682-1683)

The organ in the church of St. Jacobi, Lüdingworth is an early work of Arp Schnitger, built in 1682–83. Schnitger re-used the entire pipework of the Hauptwerk and Brustpositiv divisions from the earlier instrument by Antonius Wilde. The sound of the late Renaissance organ built by Wilde in 1598–99 is strongly felt in the present instrument! Thus the organ is a highly suitable instrument for Renaissance organ music.

The organ consists of 35 stops across three manuals and pedal. The Hauptwerk offers a full range principal plenum, based on a 16 foot Quintadena. The Trommet 8 possesses the characteristic North German sound. There is the specific Schnitgerian Zimmel, composed of Quart and Sext, offering a non-harmonic series of overtones that resembles the sound of jingle-bells. This Zimmel is never used in a plenum. It is a solo stop used exclusively in fast soloistic passages. The Hauptwerk is complemented by the smaller plenum of the Rückpositiv, where the Terz sound dominates (two Terz stops: Sexquialter and Tertian) as an alternative to the RP Mixtur. The full sound of the Rückpositiv is crowned by the presence of a mighty reed, Dulcian 16. The pedal is a fully independent division with its own principal plenum, and it gives a solid foundation to the sound of the organ with its Trombone 16 and a Trommet 8. The small reed, Cornet 2, is used for pedal solos. A special feature of the design is the asymmetric size of the two pedal towers due to the uneven height of the church ceiling. Thus the largest pipe of the Southern tower is F, while the C, D, E tones all sit together in the Northern tower. The typical renaissance Brustwerk is founded on a reed stop, Regal 8. It was enlarged somewhat in the virtual model with an 8 foot Gedacht. As the result, the model offers 36 speaking stops. In addition, there are two toy stops: a Zimbelstern and the Vogelgesang (Rossignol), indispensable for early music. The pitch of the organ is about one semitone higher than a modern standard pitch a = approx. 469 Hz. The Tremulant acts on the entire instrument.

The organ was well maintained through the 18th and 19th centuries. In the time of the Organ Reform Movement, the organ received much attention. Unfortunately, during this restoration of 1960–61, major changes were introduced: the wind pressure was lowered, the cut-ups of pipes were lowered, the windchests were given concussion bellows and the action was modified. All these changes were undone in the careful restoration of Jürgen Ahrend in 1981–82. The meantone temperament was re-introduced. Since then, the organ in Lüdingworth has once again become one of the most important witnesses of the North German organbuilding.


The samples are offered in 48kHz/24bit resolution. The multiple releases have three levels: short, mid and long. Hauptwerk v4.2 and higher supported. The sample set is offered in plain wave format.

Reverb time

The reverb time is ca. 2 seconds.

Keyboards, pedalboard

The original compass of the keyboards is 45 keys (C, c3), the low C#, D#, F#, G# missing. Dedicated mixer switch in Hauptwerk allows for the expanded chromatic compass to 54 (f3) keys virtualy. The original compass of the pedal division is 25 keys (C,D,E-d1), extended to the full chromatic compass up to f1 in the sample set.


All ranks were recorded with the Tremulant for the most convincing tremulant behavior. The ranks are marked "tremmed" in the rank description.

Surround format

The sample set is offered in the Surround variant (6 channels). There are front-direct (semi-dry) channels, featuring the sound of the organ immediately in front of the organ case. The diffuse perspective captured the sound in the church, further from the organ. The rear perspectives is designed for the rear speakers of the audio setup (where available). The perspectives can be mixed together freely to achieve any virtual listening position, or used separately - depending on the prefererences of the user. A dedicated "mixing desk" is available in Hauptwerk to mix the sound to the desired level.

Console view:

This is the general console view. It serves to define the keyboard MIDI inputs for all the divisions. The active part of this view are the manuals, and the pedal. The stop buttons are also active, but too small to be useful for manipulating by a finger. Specifying the MIDI inputs is done by right-clicking on the desired manual or pedal.




Mixer view:

The virtual listening position is adjusted here. Dragging the sliders downwards means to mute the mic perspective, dragging them up is making it louder. The mixer settings can be stored, retrieved, reset. 3 different mixer settings can be stored/recalled any time. The switches on the right bottom make:
1.) the selection for the tremulant between the sampled tremulant and artificial (Hauptwerk model) tremulant possible.
2.) The blower switch should be always on. When off, the wind to the organ will stop and there will be no sound.
3.) The compass selector allows to play either the original organ compass, or the extended one.
4.) Pipe coupling serves to adjust the amount of "chorus effect". Higher slider position gives more overall mistuning to the organ pipes, possibly giving rich and tasteful organ sound. Lowest position of the slider offers the organ perfectly in tune instead (especially when combined with Hauptwerk Temperament charts).
5.) Pipe detune - sets the overall mistuning o pipes. In the minimum position, the organ is exactly in tune (when some Hauptwerk temperament chart is used).
6.) Mixtures fine tuning: toggle between the recorded natural mixture sound which is usually somewhat beating, and perfectly tuned mixtures.
Note: toys slider controls the volume of the Zimbelstern and Vogelgesang. It also controls the volume of the Tremulant noise! All the three noises are controled together. To control the volume of each entity individually, use the Hauptwerk voicing (Organ menu). Select the "Toys" rank: there is a Toy rank for each perspective, direct, diffuse, rear. For each of the toy perspective, the slider "36" controls the Tremulant noise. The slider "37" controls the Zimbelstern volume, and the slider "43" controls the Vogelgesang volume. [In Hauptwerk 4, do not forget to re-trigger the stop switch to hear the volume change.]





Stops view:

All stops of the instrument can be accessed from a single screen. Each stop can be MIDI-learned by right click.





Left+Right Jambs view:

All the stops and other controls of the organ can be found also here. The layout for dual touch screens. The design allows for portrait or landscape orientation, according to the orientation of the touch screens.




Left + Right Jambs Vertical view:

the dual stop jambs offer vertical (portrait) orientation as an alternative.






Simple Jamb:

simplified version of a single jamb to allow for more readable version of the stop names on small LCD touch screens. There are two variants: landscape and portrait. All the stops of the organ can be found here. Physical pistons or draw stops can be assigned to a virtual button on screen by right-clicking on the button.
