System requirements
of
the Van Leeuwen organ from the Boezemkerk in Bolnes


The computer

To play the full version of this sample set without restrictions requires a modern, fast computer.
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 Van Leeuwen organ can be downloaded.
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, 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!

J.P. Teeuw - Improvisatie over een thema van Bach
The Boezemkerk and "the red organ"

The Boezemkerk was founded in 1957.
The organ was commissioned in 1960.
The organ was built by Willem van Leeuwen Gzn, an organbuilder in Leiden, using the purely mechanical VEKA windchest-system.
The organ has 18 speaking stops.
The organ is viewed as a good mechanical instrument, built along generally accepted norms of that period. Considering the specification as well as the construction year one would expect a neobaroque organ, but that's not the way the organ sounds. It has its own characteristic sound.
The organbuilder called it "the red organ" because the colour of the organ case.

Technical div

Tuning: a' = 440 Hz.
Transmitting system: The organ action is completely mechanical with VEKA-system windchests.
