Manual:
The keyboard can be shifted a semitone to the right and because an extra pipe is installed on the chest, one can play a semitone higher without running out of pipes.
The organ builder did this to make it possible to play along with the Hinz main organ.

Coupler:
The actual organ has a pull-down pedal. To make the organ more useful, we have provided it with a copy of the Bourdon 16 foot from the main organ in this church. This made it necessary to equip the instrument with a pedal to manual coupler.
Of course the pedal also shifts when the keyboard is shifted.

System requirements
of
the Mense Ruiter choir organ from the Petruskerk in Leens



The computer

To play the full version of this sample set without restrictions requires a modern, fast computer with, for example, Windows 10 64 bit installed and around 4 GB of RAM.
Obviously Hauptwerk must also be installed with the latest version 5 (or higher) Advanced.
It is said that the best results are achieved using Apple-MacIntosh computers; however, we have no experience with this. It is difficult to make exact statements about what is needed. The "mother" website hauptwerk.com provides much information about this issue.
Prerequisites
.
This virtual Mense Ruiter choir organ can be downloaded after purchase. Below is a table of memory usage .
On other systems, these values can vary considerably! Please note that your Operating System also requires considerable memory.


The sound card

A good internal or external sound card. For more information go to: hauptwerk.com .


Manuals/keyboards/pedal òr complete organ with MIDI out

1 manual/keyboard and a (at least 25 keys) pedal òr a complete electronic organ with MIDI out.
Beautiful consoles specifically designed for Hauptwerk are commercially available.
In the Netherlands these are available through, for example,

Those who are technically inclined can provide their keyboard with MIDI capability using hardware from, for example, WIRA, MIDI-Hardware.com or MGB . We ourselves have done this using a Heyligers organ dating from around 1975 (using WIRA hardware). The conversion was about 300 Euro and everything has worked perfectly for years.


Speakers/headphone

The superb sound quality of Hauptwerk is best experienced through high-quality headphones, such as AKG or Sennheiser.
We prefer connecting the sound card to a (possibly multi-channel) sound system. The above mentioned companies can also advise you on any purchases in this area.
What you definitely should not do is listen to Hauptwerk through the built-in speakers of the monitor or a set of €10 computer speakers!

G. Muffat - Aria con variationi
Historical information

The organ was built in 1982 by the organ builder Mense Ruiter of Zuidwolde, Netherlands.

This sample set is made from a recording made in the Petruskerk in Leens, Groningen, on October 10, 2007.
The recordings were made by Fred de Jong and Rietje Raatgeep.
Initially we refrained from the publication of this organ because of the very disturbing and difficult to remove motor noise.
Upon reflection and with much effort we were able to obtain an acceptable result which we do not wish to withold from you.
Most of the work involving the samples was done by Johan van der Waal van Dijk.
The Organ Definition File and thus also the layout was created by Fred de Jong in the summer of 2013.

Technical Information

Tuning: a' = around 436 Hz.
Temperament: Equal temperament.
For Hauptwerk, the sample set was retuned to equal temperment at a' = 440 Hz.
Windpressure 65 mm (2.56 inch) column.
There is no tremulant.

Recording Technique

The organ was recorded in stereo (24 bit, 96 kHz) at a distance of about 2 meters from the front.

Alternative Tunings

If you should use an unequal tuning, then you will notice that when the keyboard is shifted (one semitone higher) the tuning is no longer correct. For this reason we have created extra temperaments which are included with this organ.
200 Well-Temperament: Kirnberger III+semitone.
201 Well-Temperament: 1/7 Comma+semitone.
202 Well-Temperament: 1/6 Comma Vallotti-Young+semitone.
203 Well-Temperament: Werckmeister III+semitone.
244 Mean-Tone: 1/6 Pythagorean Comma+semitone.
245 1/8 Comma+semitone.
246 Just Intonation: Natural+semitone.
247 Just Intonation: Pythagorean+semitone.
248 Mean-Tone: 1/5 Pythagorean Comma+semitone.
249 Silbermann Organ, Erfurt Dom+semitone.
