The Steendam organ from the
Eben-Haëzerkerk in Apeldoorn
€ 299,-
In October 2012, we recorded the Steendam organ from the Eben Haëzer
Church in Apeldoorn for Hauptwerk.
This organ features 2 manuals and a full pedal.
Originally designed with 31 stops, but some of them are (yet) to be
installed. For Hauptwerk, we have added the missing stops as much as
possible.
Only available in the version for Hauptwerk 4.
About the builder
Orgelmakerij Steendam
is located in Roodeschool in the province of Groningen, in the most
northerly city in the Netherlands. Since 1986, Orgelmakerij Steendam
has built, rebuilt, restored and renovated organs ranging from chest
organs to three manual organs with independent pedal. The organs of
the 19th century organ builder, C. G. F. Witte, his predecessor, Batz,
and the organ builder Christiaan Muller stand centrally as inspiration
for the organs of Orgelmakerij Steendam. This means that all work is
performed using historical methods, with an eye to technical and
musical details as already used for centuries of organ building.
In addition to organ building, Orgelmakerij Steendam also busies
itself with the appraisal of organs, the construction of church
furnishings (mostly in the context of organs) and, for two weeks per
school year, Sicco Steendam is guest lecturer (organ building) at the
Music Academy in Moscow. In the shop in Roodeschool organs up to 16
feet in any dimension are built. All drafting is carried out in their
own shop, and this makes possible close consultation with the client
and the fulfillment of almost every wish. Throughout, sight is never
lost of the function that the organ is going to serve and the final
result is attuned as much as possible to the building in which the
organ is placed.
For Sicco Steendam the love of organs is number one. Contributing to
the preservation and expansion of the rich organ treasure in the
Netherlands and surrounding countries is a major motivator for this
organ builder.
The Eben Haëzerkerk in Apeldoorn (1995)
The Eben-Haë zerkerk
is one of the largest churches in Apeldoorn. The church building was
opened on the sixth of October, 1995, and was built as instructed by a
neighbourhood congregation established in 1979 and associated with the
PKN. As such it is aligned with the Gereformeerde Bond. The building
was conceived by Valk architects in Soest. In addition to the large
auditorium with room for 750 to 800 persons, the building has a
variety of halls where church meetings take place and where
associations meet.
The Steendam orgel (1997)
On February 21, 1997, the Steendam Organ was inaugurated by Marcel van
de Ketterij and Peter Eilander in a service for parishioners and other
interested parties. At the time it was an instrument with 19 ranks and
a fair number of prepared for ranks. In the mean time, 4 ranks have
been added, namely the Open fluit 4' and the Sesquialter II to the
Hoofdwerk and the Salicet 4' and the Dulciaan 8' to the Zwelwerk. As
requested by the congregation it became a romantic instrument well
suited to supporting congregational singing. A large part of the organ
literature may also may be interpreted faithfully, in particular,
romantic works, and not in the least because of the very effective
swell.
The organ case, as well as other church furnishings, are made of ash.
Because the organ builder and the architect of the church were able to
collaborate at an early stage, the organ is one with the building. The
facade is dominated by a stately central tower displaying the largest
pipes of the Hoofdwerk. The upper pipe fields also indicate that the
organ possesses a Bovenwerk. In Apeldoorn the situation is such that
the pipe work of the Bovenwerk is placed in a swell box which may be
operated by hand or by foot.
Permanent organists at the Eben-Haezer kerk are:
Peter Eilander, Marcel van
de Ketterij and Arie Kortleven.
Technical information

About the recordings
Three channel technology
This sample set was recorded from different 3 positions in stereo (24
bit 96kHz).
The set comes with a 3 channel technique developed by Sygsoft which
makes it possible for the listener to alter his listening position.
There are three positions, namely:
1: Front, recorded very close to the organ. Here you will hear a very
direct recording well suited for studio purposes.
2: Middle, this recording was made from a distance approximately 3 x
as far as the front recording.
3: Rear, far away from the organ, and useful for surround sound.
By means of 3 sliders (0 - 100%) one can mix these three positions
according to taste.
Other details
The recordings for this sample set were made from October 8th to
October 13th, 2012.
Recording quality: 96 kHz 24-bit, reduced to 48 kHz 24-bit for the
set.
Number of microphones: 6
Estimated number of hours worked on this set: 2,200
Number of samples processed in this set: 29,665
Number of files in this set: 30,082 in 684 folders.
Number of lines in the Organ Definition File: 1,811,153
Number of kilometers driven for meetings, trial, and final recording:
900.

Specification
of the Steendam organ from the Eben-Haëzerkerk in Apeldoorn
Tremulant:
The tremulant works on the Zwelwerk. We have included the tremulant in
its entirety.
Note that no. 10 Schalmey 8' is not present on the actual organ.
Since the tremulant also clearly affects the Hoofdwerk, we have
recorded this effect as well, according to the following scheme:
No tremulant was recorded because the effect is barely
noticeable.
From key 60 t/m 91.

Insert the dongle into the Hauptwerk PC (if it is not already connected to it).
Detailed explanation point 3: (It turns out this is not clear to everyone)
3a: Go to your iLok account (log in if necessary),
select the sampleset for which you want to enter the activation code.
3b: At the top right of the iLok screen is a gray/green check
mark.
If you go over this with the mouse you will see the text
'Activate licenses'.
Click on this check mark and you will see a new screen.
3c: Click on 'Activate' and 'Ok'. Now the checkmark in the previous
screen turns green.

System requirements
of the Steendam organ from the Eben-Haëzerkerk in Apeldoorn
a modern fast computer, minimum 12 GB RAM and e.g. Windows 10 64 bit
a good internal or external sound card
2 manuals/keyboards with (at least 25 keys) pedal òr a complete
electronic organ with MIDI out
good quality speakers /headphone
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 12 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 .
Please note: This information applies to the newest version of
Hauptwerk.
This virtual Steendam organ can be downloaded. The set is protected
with the Hauptwerk Protection System via the
iLok account or dongle from your
Hauptwerk program.
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
2 manuals/keyboards 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!
Table of memory usage of
the Steendam organ from the Eben-Haëzerkerk in Apeldoorn
Hauptwerk 5 (space needed on the hard drive is 37 GB)
The meaning of the columns:
A = Front, Middle or Rear samples loaded (1 channel)
B = Front + Middle, Front + Rear or Middle + Rear samples loaded (2
channels)
C = Front + Rear + Middle samples loaded (3 channels)
D = tremulant samples loaded

De nrs. 1-2-3-4-5-6: 14 bit (it is possible to use, but we find that
14 bits provides insufficient quality).
De nrs. 7-8-9-10-11-12: 16 bit (slightly better, but still single
release.)
De nrs. 13-14-15-16-17-18: the standard Hauptwerk loading mode: 16

De nrs. 25-26-27-28-29-30: 24-bit, compressed and multi release.
De nrs. 31-32-33-34-35-36: the maximum attainable loading mode:
24-bit, uncompressed multi release. Of course there are many more
variants, e.g., load the pipe samples in 24 bit and sounds in 16 bit,
etc. If you need assistance, contact us via the

Screen layout
of
the Steendam organ from the Eben-Haëzerkerk in Apeldoorn
Tab A : Foto's (Photos)
This page shows the front of the organ and if you click on the photo
you will see the key-desk which is positioned to the left of the organ
as seen from within the sanctuary.
Tab B : Speeltafel (Console)
The arrangement of the draw knobs was designed by Steendam. The LEDs
indicate which tremulant combination was chosen.
With the slides Front, Middle and Rear, you can adjust the
relationship between the various channels and thereby determine your
listening position. Should you prefer a more direct sound then assign
a higher value to Front and a lesser value to middle and rear. Should
you prefer a more indirect sound, then assign a larger value to middle
and rear.
The fourth slide is the swell pedal.
Above the keyboards, you will find the 5 tremulant combinations for
the Swell and a corresponding Reset. Beside the Violon 16' you will
find a button "12" which turns on the Violon 10 2/3' and next to the
Bazuin 16' you will find the Bazuin 32'. Both are copies. As was
already mentioned above, Steendam made provision for the ranks that
are underlined but they have not (yet) been installed. To at least
give you an impression of how the organ will sound someday, we added
them by deriving them from other ranks.
The buttons 12 and 32 turn on the Violon 10 2/3' and the Bazuin 32'
respectively. This is one of our inventions and these stops will never
be added to the organ.
The button labelled "Calcant" turns the blower on as well as the
lighting for the music rack.
Since the pedal is not visible on this page, green LEDs serve as
indicators.
Tab C : Schakelaars (Switches)
Most of the elements on this page need not be visible, but for those
who are interested, it gives some impression of all that has to happen
to get a sample set of this size working. Just think that behind each
(manual) key there reside 56 long, 56 long release, 56 middle release
and 56 short release samples.
The "Auto combination" button switches on and off the only
tremulant combination recorded for the hoofdwerk.
The "Trem. recorded" and "Trem. Hauptwerk" buttons work
together with the Hauptwerk logo on the "Speeltafel" page to switch
between the recorded tremulant and Hauptwerk's electronic tremulant.
Refer to the explanation (Hauptwerk tremulant system) under Features
above.
In addition, you will find the buttons
"Trekker geluid" (Tracker noise) and "Toets geluid" (Key
noise) which are self explanatory.
Tab D : Wind (Wind Supply)
On this page you will find a schematic representation of the wind
supply for this organ.
With various sliders you can regulate the wind going to the bellows
and various wind chests.
With the "R" or reset button, you can return to the arrangement which
in our opinion gives the best results. With the button labelled
"Sygsoft" located underneath to the right you can reset all 6 sliders
at once.
Important:
Should you decide not to load the complete sample set (e.g., your
computer's RAM memory is insufficient and you decide not to load the
Rear samples) then reduce the wind supply by 33% thus reducing the
sensitivity of the organ's wind supply to less than that of the actual
instrument. In that case go to Organ settings/Organ preferences/Wind
supply model and choose a value of around 150. In case you have loaded
only a single position, e.g., "Middle" (thus reducing wind needs by
66%) then you should adjust this value to around 300 to achieve the
same result. Of course you can select whatever value you wish should
you not like the response of the organ.
By means of the checkmark on the wind-supply-model page you can turn
off the complete wind supply.
Special features
Recorded tremulant combinations
Because combined tremulant samples are never in phase, we have
recorded some frequently uses Tremulant-voice combinations namely from
the Hoofdwerk: Combinatie I: Octaaf 8'; Roerfluit 8'; Open Fluit 4' and
Cornet.
This switches in automatically (only with tremulant) if these voices
are selected.
Should you not wish this automatic switching to go into effect, go the
the menu item"Couplers" and select in the column "Hoofdwerk" the
button marked "Auto combination."
The LEDs under the drawknobs indicate whether the combinations are in
effect.
For the swell we recorded 5 Tremulant-voice combinations: By means of
the buttons marked by a red arrow (See figure 2) you may select these
combinations. Here also, the LEDs under the drawknobs indicate which
combination is chosen.
Reset the last chosen combination.

Recorded tremulant or Hauptwerk tremulant:
Because recording the samples with tremulant made the sample set
almost twice as large, we have also supplied the organ with an old
fashioned Hauptwerk tremulant. For all voices recorded with tremulant,
2 samples per key were made. Should you wish to not load the complete
set, because it demands too much memory from your computer, you can
begin by omitting all ranks whose names end in "Trem." After loading,
click on the "TR" button near the tremulant (the button must be blue,
see fig. 5) and you will hear the Hauptwerk tremulant. Remember that
now you cannot use any of the recorded tremulant combinations (see
heading 6B). Now, via voicing, you can adjust the tremulant according
to personal taste. Remember that all adjustments must be carried out 3
times for Front, Middle and Rear. To reach the correct voicing page,
right click on the relevant buttons on the page "Schakelaars".
