What is important when choosing a Hauptwerk organ?

Two loudspeakers, a left speaker and a right speaker form the mediator between the two microphones, which recorded the sounds in the church in the place of the organist. The Hauptwerk organ is not an independent organ, but it bridges the gap between the organ in the church and the rendition into the living room. Next to my Hauptwerk organ is my chamber organ with pipes, which I made and voiced myself. I can compare the sounds of the Hauptwerk organ with the pipe sounds.

Organists with a Hauptwerk organ often want the organ to look like a pipe organ. A pipe front for the loudspeakers must reinforce this illusion. In my attic there are a large number of pipes that I have kept from my sound research, but I find it pointless to place them in the organ front. They are not useful.

There are big differences between pipe organs, depending on practical requirements and personal wishes. This is no different for Hauptwerk organs and everyone can choose their own wishes. However, it is advisable to consider the best reproduction of the pipe sound from the samples.

In addition to the pipe sounds, the sample sets also contain extra sounds, such as the wind motor and the tracker actions. With my pipe organs I have always placed the wind motor in an effective damping box. My tracker action tools worked without noise. I have played in hundreds of churches, but no one has ever heard that I have pulled the stops. This has to be quiet and without sound, otherwise it disturbs the music. Therefore, I never install the sounds of the sample set; they prevent making music.

Two loudspeaker at close range and focused on ears organist bring sounds good to the living room. It makes no sense to use multiple speakers for these sounds. Separate speakers for the treble is well worthwhile to use and of course there must be a good subwoofer for the bass. The location of the subwoofer is insignificant, because the bass have no directivity.

Headphones are undesirable for several reasons, see here, but the main reason is that sounds be in proportion to the area. The choice of the registers depends on, it may be too loud or too weak or too sharp or too thin. The music has an air transfer. Headphones concludes that environment. Compare it to painting, for which a well-lit workshop is required. A spotlight on the subject plus a light on the canvas is not enough to assess the relationship of the colors.

Orgelmakerij Noorlander in Barneveld

At Orgelmakerij Noorlander every part is manufactured in the company and forms a link in the chain to a beautiful organ sound. Everything is coordinated with the aim of making the organist at home hear sounds as an organist hears in the church.

Kees Noorlander knows the sounds of a pipe organ and he designs Hauptwerk organs that make the organ in the living room sound like a church organ. His employees also have a thorough knowledge of good pipe organ sound. As a pipe organ builder I could talk to people who know the trade and I missed that at other companies.

The Sonnette III completely matched my wishes and with carefully chosen sample sets the sounds are no different from the organs in the church. A Hauptwerk organ must reproduce the recordings with good speakers in the right place. Then the sounds are realistically transferred to the living room.

Hauptwerk organ as a Chamber organ

Pipe organ builders prefer to build for churches, because the sounds need good acoustics to develop. Many organ builders refuse to build a house pipe organ. Small house organs with one or two flute registers achieve a pleasant sound in a room without acoustics and are often built by amateurs. They sound great together with recorders.

Hauptwerk is the ideal organ for the living room. The sounds of the church organ are stored as samples in a memory and sound exactly the same as in the church. With the new technique of Hauptwerk 5, the memories only have to contain the sounds.

The acoustics of the church follows a different path and is already present in the organ. Just as in the church the sounds from the pipes are developed through the acoustics, so does the sounds from the samples. Hauptwerk 5 has made an ideal copy of the church organ possible, by using the Impulse-Response technique. This technique is an exact copy of the acoustics of the church and is referred to as convolution reverberation.

All sample sets of Hauptwerk 4 already present sound with this new reverberation in Hauptwerk 5 as if they were new recordings that are being played in the church.

A Hauptwerk organ shows original pipe sounds with their reverberation in the church. Next to the Hauptwerk organ is my house pipe organ with well-voiced metal pipes and organists can compare both organs. Unfortunately the pipes have no acoustics and that is the reason that the pipe organ is rarely played anymore.

Most organists have exchanged their pipe organ for a Hauptwerk organ. Now they can rehearse the concerts at home under the same conditions as in church. The Hauptwerk organ is the ideal home organ. The convolution reverb adds acoustics to this, like the organist who hears at the console in a church.

The sounds of the samples are recordings of pipes in the church. The main requirement is that all the properties of the pipe sounds are transferred. A well-recorded sample set is a prerequisite, but also that speakers are placed at the height of the organist's ears and are accurately aimed.
