F. van Tilburg - Komt laat ons voortgaan kindren

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 div 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.

About the recordings


Three channel technology
sliders_steendam.png
Sliders on the tab "speeltafel" (virtual console)

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 div

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.

Download files: Once we receive your payment, you will gain access to the download files via email.

Important : Before download, first read the comments below at 'General'.

General
Installing a sampleset

Important: Download the latest licensing packages file https://www.hauptwerk.com/licensingpackages/
Start Hauptwerk V (or higher) and install this file via the menu File | Install Organ, Temperament, or Impulse Response Reverb... Hauptwerk will 'learn' which protected sets are currently on the market.

For users of Hauptwerk 5 or higher:
1. Make sure that Hauptwerk is not loaded.
2. Open your iLok account and choose 'Licenses/Redeem Activation code',
cut and paste the many-digit code into the screen.
3. Activate your license to 'iLok Cloud' or to the 'iLok dongle'.
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.
  • 3d: Now double-click on the sampleset you bought, the screen that opens must show "License status active" on the top line.
  • 3e: If necessary, repeat the above for the eventualy other newly purchased organs.

4. Restart Hauptwerk and you can install and use the organ.

Before download and install, note the following:
1. Download all .CompPkg.Hauptwerk files.
2. Leave these files in the same folder and
3. Do not change the file names and
4. Do not unpack by hand.
5. Check the MD5 checksums with the WinMD5 program, free to download from
http://www.winmd5.com or http://www.fastsum.com
If a checksum is incorrect, discard the wrong download file from the PC and download that file again.
6. Start Hauptwerk (File/Install organ....), select in the folder where you just downloaded the files,
the file with extension .CompPkg_Hauptwerk_rar in Hauptwerk's 'component installer'.
Hauptwerk automatically finds the other files.
7. If you get error messages, scroll to the end of the log file (this opens automatically if something goes wrong when unpacking) to see what goes wrong.
Usually a file is missing, or there is a file in the wrong folder or a file is damaged.
8. Before loading the sampleset, check the system information regarding the expected memory usage etc.

Note: Please contact us via the Contact form if you encounter any issues; we will try to assist you.

System requirements
of
the Steendam organ from the Eben-Haëzerkerk in Apeldoorn



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, 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

Console

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)
steendam_10_klein.jpg
The virtual 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)
steendam_11_klein.jpg
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)
steendam_12_klein.jpg
Model of 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.

Fig.5: Hauptwerk tremulant
steendam_06.jpg
Fig.6: Recorded 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".
