In 1821 the Oude Kerk received its first organ, built by the organ builder J.F. Friedrichs who made use,
among other things, of the organ the Joh. Baars had built in 1779 for the Walloon church in Naarden.
When completed in 1821, the organ had the following disposition:
Hoofdwerk: Prestant 8', Roerfluit 8', Octaaf 4', Nachthoorn 4', Quint 3', Octaaf 2', Cornet disc, Dulciaan 8'
Bovenwerk: Roerfluit 8', Viola di Gamba 8', Salicionaal 4', Fluit 4', Gemshoorn 2'
Pedaal: Attached
Couplers: Hoofdwerk-Bovenwerk, Pedaal-Hoofdwerk. Tremulant on the bovenwerk.
Manual Compass: C-f''', Pedal Compass: C-D'. Temperament: Equal. Pitch Level: a'=440 Hz.´
Bovenwerk: Roerfluit 8´ , Viola di Gamba 8´ , Salicionaal 4´ , Fluit 4´ , Gemshoorn 2´
Pedaal: Fixed
Coupler: Hoofdwerk-Bovenwerk, Pedaal-Hoofdwerk. Tremulant on bovenwerk.
Compass: C-f´ ´ ´ , Pedal compass: C-D´ . Tuning: Equal. Pitch: a´ =440 Hz.
The New Organ:
With construction of the current church, it was eventually decided to also build a new organ and in the
same Gothic Revival style of the new church. Artistically this turned out to be a fortunate choice.
The organ, built by the organ builder Batz, was put into use on November 5, 1843.
In 1909, De Koff placed the bovenwerk inside a swell enclosure and replaced the Gemshorn 2' with a
Voix Celeste 8' and the Trombone 8' with a Fagot 16'.
In 1977, Verschueren restored/conserved the organ using 1843 as starting point.

3. Technical information:
|
Windpressure: 70 mm (2.76 inch WC)
Tuning: a' = ca. 434 Hz.
Temperament: Equal (Of course in Hauptwerk this can be switched to another temperament)
Tremulants
On the real organ is no tremulant for the Hoofdwerk provided. We have added one for Hauptwerk.
The tremulant for the Zwelwerk is duplicated: 1st: Integral recorded and 2nd: Modulated.
Not everyone likes the original tremulant, in this case you can then choose the modulated tremulant and as usual
change everything including speed and depth.

This sample set was recorded from three positions in stereo (24 bit 96kHz).
The set comes with a Sygsoft devised 3-channel technique whereby the user may set the listening position themselves.
There are 3 positions, namely :
1: Front, recorded very close to the organ. This provides a very direct recording that is useful for study purposes.
2: Centre (Middle), this recording was made at about 3 times the distance used in the front recording.
3: Rear, recorded far from the organ is used as surround.
Through three sliders (0-100%), a mix can be made of the three positions that is to your liking.
The 4th slider (with the caption "Vol-ZW") is definitely not a swell pedal but a volume control for the entire Zwelwerk.
Using the button "R" switches it back to the normal volume.
The 5th slider controls the Swell.
While the pedals are not visible we have on the black tab below the Hoofdwerk LED's mounted to show wich key is pressed.
The adjacent picture is a representation of the original console. All extensions we have placed on the "Advanced" tab also
more suited to touchscreen users. For more see the Consoles page.
