In January 2014, we recorded the Lohman organ in the Grote or St.
Catharinakerk in Heusden, in the Province of North Brabant.
The well-known Lohman organ from 1824/1828 has 29 stops distributed
across 2 manuals and a pedal.
As usual, the sample set is released using multi-release technique on
all stops.
The Great or Catharijnekerk
Until 1944, an organ with Hoofdwerk, Rugpositief and Pedal stood in
Catharijne Church. Built in 1840 by C.F.A. Naber from Deventer, it was
lost in 1944 when the tower collapsed as a result of war.
After using a "temporary organ" from the firm Valckx & Van
Kouteren for more than 35 years, the Reformed Church, in December
1980, bought the organ from the former Broederenkerk in Zutphen. This
organ was built between 1824 and 1828 by N.A. Lohman & Son and
made use of the organ, placed there by AFG Heijneman, from the former
Sint-Janskerk in Arnhem. The instrument originated in Huijse
Schaffelaar in Barneveld.
The starting point for the design of the organ front in 1824 was the
Lohman organ at Eenrum (Gr.).
In 1894 the organ was cleaned and restored by J.F. Witte, and, amongst
other work, the case was repainted, pipework was restored and some
were provided with tuning cutouts (expressions). In 1938 the firm J.C.
Sanders & Son carried out a restoration which included
electrification of the pedal action and expansion of the Rugpositief.
The dismantling in Zutphen and restoration and reconstruction in
Heusden was carried out by Orgelmakerij Gebr.Reil Heerde, under the
advice of Drs. J.J. van der Harst. The organ, as it was in 1828, was
used as a starting point. Meanwhile the case was made about 1 m
shallower.
The drawknobs installed by Sanders were replaced by Naber stop knobs,
from the organ in the Alkmaar Sint Laurens Church. The carving around
the feet and of the wings was redone, as well as the pinnacle. On
Saturday, September 22, 1984 the organ in Heusden was officially
inaugurated.
De Restoration 2007
In 1984, the company Reil restored the Lohman organ, which originated
in the Broederenkerk in Zutphen and was moved to Heusden.
In the following years, the instrument was not well maintained and a
movement began to restore the organ thoroughly.
Peter van Dijk was hired as a consultant on behalf of the Commission
Organ Affairs of the PKN.
The local church stewards established the Commission for Organ
Restoration, which included organists among its representatives.
In consultation with Peter van Dijk a recovery plan was established,
after which tenders were prepared by a number of organ builders. The
contract was awarded to the firm of Reil. The work included cleaning
the interior and the organ pipes, repairing chests, checking all
pipes, revoicing where necessary, and tuning of the entire
instrument.
The voicing was reviewed by Wim Wagenaar, who had done this work in
1984! In the spring of 2007 the job was completed and advisor Peter
van Dijk provided a festive inauguration on 26 May.
Reil has regained the responsibility for maintenance of this organ!
The Great or Catharijnekerk
Oudheusden has been inhabited since the 8th century. At that time,
there was mention of a fortified place, a "Castle," at the Oude
Maasje. This castle, which bore the name 'Nieuwenrooy', stood on the
site where the current public school 'Nieuwenrooy', was built.
The church of Oudheusden after being destroyed several times since the
French period was not rebuilt. Because the course of the Meuse is
increasingly shifting northward, it already created in the 12th
century the need to build a fortified place elsewhere.
In the immediate vicinity of the castle the fortified town of Heusden
established itself over the centuries. Already in the year 1210,
mention is made of a church in Heusden. What the church looked like is
not known. What was left, namely the tower built in Romanesque style,
was destroyed in 1944. In 1328 the church was extended with a north
and south aisle. There was also a choir in Gothic style.
In 1555 a transept replaced the north aisle and three bays were
constructed in alternating layers of brick and stone. Here we still
find decorations in Gothic style.
A city-wide fire in 1572 destroyed large parts of the church. Starting
in 1579 a thorough restoration ensued.
The side choir, probably built in 1412, was torn down in 1628. The
location of this side choir is still visible in the masonry. In the
years 1637-1639 the choir was renewed.
The tower was blown up during the nights of November 4 to 5, 1944 by
retreating German troops. The western part of the church was also
destroyed. After the war, the church, on its west side, was closed in
and restored. The tower, the western chapels and the devastated bays
were not rebuilt.
The circumference of the foundation is visible in the pavement. In the
church one can find, in addition to beautiful gravestones and signs
from the 16th and 17th centuries, bells from 1334, 1501 and 1518. A
bell from 1412 now hangs in the turret.
The mausoleum of the Baron Van Friesheim, Governor of Heusden from
1711-1733, dates from 1733 and is very beautiful. The design of this
tomb is by Jacob Marot and the sculptor was Jan Baptist Xaverij.
Technical information
Wind pressure: 70 mm
Tuning: a' = ca. 435 Hz. (Hauptwerk 428,4 Hz.)
Temperament: Werckmeister III. (Of course in Hauptwerk this can be
switched to equal temperament or another temperament)
Tremulant Hoofdwerk:
This tremulant works on most voices of the Hoofdwerk. With the
exception of the Bourdon 16' and Mixtuur, all voices were recorded in
full. But let it be noted that the Flute 4' and the Trumpet 16' are
not present on the real organ.
Tremulant Rugpositief:
This tremulant works on the Rugpositief. Only the Praestant 8' disc.
and Dulciaan 8' were recorded. Hauptwerk provides a tremulant for the
remaining voices.
About the recordings
Three channel technology
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.
Comments on the two tremulants
The hoofdwerk has no tremulant; however, we were still able to record
(almost) all the voices of this division with tremulant via a trick
invented by the organist: by depressing some 20 keys simultaneously
(without any stops drawn) on the Rugpositief, the tremulant is
transmitted to the Hoofdwerk.
Unfortunately, the tremulant on the Rugpositief does not start when
air consumption is low. Thus we only managed to record the Praestant
8' and the Dulciaan 8' with tremulant. To the rest we were forced to
apply the "Hauptwerk" tremulant. We extracted the required waveforms
by recording several three-note chords for each of the corresponding
voices.
Other details
The recordings for this sample set were made in January 2014.

of the Lohman organ from the Grote or Catharijnekerk in Rotterdam
Important: The following files cannot be used in Hauptwerk
version 4 or older versions.
Before you proceed with installation, please read the notes under
'General' at the bottom of this page.
Improved version 2020-01-14
We recommend that you fully uninstall the previous version(s). You can
keep any combinations and audio routing you have made.
With the new version Hauptwerk 5 the wind model is a bit too
"aggressive". To reach the old HW 4 situation, go to Hauptwerk to
Organ settings/Organ Preferences/Wind Supply Model tab and choose a
value of approximately 75 for "Windmodel modulation depth
adjustment%".
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:
Make sure that Hauptwerk is not loaded.
Open your iLok account and choose Licenses/Redeem Activation code
and cut and paste the many-digit code into the screen.
Activate your license to iLok Cloud or to the iLok dongle. In the
latter case: then place the dongle on the Hauptwerk PC. It appears that this rule is not clear to everyone:
3a: Go to your iLok account (log in if necessary) and select the
sample set 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 line you are working on and 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.
Restart Hauptwerk and you can install and use the organ.
Before download and install, note the following:
Download all .CompPkg.Hauptwerk files.
Load these files in the same folder and
Do not change the file names and
Do not unpack by hand.
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, throw the wrong download file away
from the PC and download that file again.
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.
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.
Before loading the organ, first have a look at 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 Lohman organ from the Grote- or Catharijnekerk in Heusden
a modern fast computer, minimum 12 GB RAM and e.g. Windows 10 64 bit
a good sound card
2 manuals/keyboards with (at least 30 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 Lohman 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 or keyboards and a (possibly 30 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
for
the Lohman organ from the Catharijnekerk in Heusden
Hauptwerk 5 (space needed on the hard drive is e.g. 25 GB)
The meaning of the columns:
A = Number of loaded channels
B = Compression applied?
C = Bit rate Pipe samples
D = Multi-release pipe loaded?
E = Organ cache (GB)
F = RAM usage, Operating System not included (GB)
Please note that the stated values are an approximation !
De nrs. 1-2-3: (14 bit), single release compressed (a possibility but
we think the quality is insufficient).
De nrs. 4-5-6: (14-bit), multi release uncompressed (a possibility but
we think the quality is insufficient).
De nrs. 7-8-9: (16 bit), single release compressed (quality is
somewhat better).
De nrs. 10-11-12: (16-bit), multi release compressed (the standard
Hauptwerk loading mode).
De nrs. 13-14-15: (16 bit), multi release uncompressed.
De nrs. 16-17-18: (20-bit), multi release compressed.
De nrs. 19-20-21: (20 bit), multi release uncompressed.
De nrs. 22-23-24: (24-bit), multi release compressed (the maximum
possible).
De nrs. 25-26-27: (24 bit), multi release uncompressed (the maximum
possible).
There are of course many more variants, e.g. pipe samples loaded at 24
bit and sounds at 16 bit, etc.

Screen layout
of the Lohman organ from the Catharijnekerk in Heusden
Tab A : Foto's (Photos)
This tab shows the organ front and console and, if you click on the
picture, you can see the church.
Tab B : Eenvoudig (Simple)
On this tab, we see a simpler representation of the stops more
suitable for users of touch screens.
All stops and playing aids specifically made for Hauptwerk are
underlined here.
Tab C : Schakelaars (Switches)
Most elements of this page need not actually be visible but are still
of interest if only to give a bit of an idea of what needs to be done
to get a sample set of this magnitude working. Just remember that
behind every (manual) stop control there are 56 long, 56 long release,
56 medium release, and 56 short-release samples. In addition there are
also 56 tremulant and 56 tremulant release samples for the Hoofdwerk.
The same applies to the pedal with 30 samples (here without
tremulant). In total approximately 25,000 samples.
Some stops are divided into a bass and discant section. The button
"REG. GEDEELD" (Reg. shared) allows you to enable or disable this
feature. The divided stops are: Vox Humana 8'; Trumpet 8'; Praestant
8' RP and Dulciaan 8'.
Furthermore, you will find the buttons "Trekker Geluid" (Draw Knob
Sounds) and "Toets Geluid" (Key Sounds) which are self explanatory.
Furthermore, it is useful to know that if you right-click on a switch,
you will be immediately directed to the appropriate voicing screen.
Tab D : Virtuele Speeltafel (The virtual console)
The arrangement of the stops follows the original as much as possible.
To make room for some additions, the 3 shutoffs and the ventil are
moved to the switch panel.
The manual coupler of this organ works by shifting the keyboard.
Because this is difficult to see visually, we simply added a stop
"Manuaal koppel" (Manual coupler).
In the curve above the panels, LEDs are placed that indicate whether
the divided registers are coupled.
The sliders "Voor" (Front), "Midden" (Middle) and "Achter" (Rear)
allows you to set the ratio of the various channels thereby
determining your listening position.
If you prefer a direct sound, select a high value for "Voor" and low
values for "Midden" and "Achter".
If you prefer an indirect sound, then you should adjust "Midden" and
"Achter" to higher values.
The 4th slide (with the caption "RP") is definitely not a swell
pedal but a volume control for the entire Rugpositief.
The button "Volume - RP reset" returns it back to the normal
volume.
The button "Calcant" turns on the blower motor.
The keyboards have been extended by 2 keys f''' to g''' while the
pedal was extended by 3 keys from d' to f'.
Tab E : Wind
This tab shows a schematic representation of the wind supply for this
organ. With the various sliders you can control the flow of wind for
the bellows and the various chests. The "R" or reset buttons,
allow you to return to the settings that, in our view, yield the best
results. With the button "Sygsoft" below on the right, you can
reset all six sliders at once.
Important:
Should you decide not to load a portion of this sample set (e.g. your
computer RAM is too small and you choose to omit all "Rear" samples)
then the wind consumption is reduced by 33% and the organ becomes much
less sensitive to the wind than it actually is.
In this case, go to Organ settings / Organ preferences / Wind supply
model and choose a value of around 150%. Should you load only one
position, e.g. "Middle," (thereby reducing the wind consumption by
66%) then you must set this value to about 300% to obtain the same
result.
Obviously you can select any value you wish if the organ's behaviour
is not to your liking. If the Wind Supply Model-tab is left unchecked,
you can completely disable its function.
Tab F : Linker- en rechterpaneel (Left- and right panel)
For players working with 2 touchsreens here a left and right screen.
The format is broadly similar to that of the tab "Speeltafel".
At the top of each screen there are 2 LEDs wich indicate whether the
shared registers are linked.
You listen to the Lohman organ from the Catharijnekerk in Heusden
