What is important when choosing a Hauptwerk organ?

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

In the orgelmakerij Noorlander, every part is made in the company and forms a link in the chain to a beautiful organ sound. Everything fits the goal of making the organists hear the sounds according to the sounds in the church.
Kees Noorlander has a good hearing for pipe sounds 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 a good pipe sound. As a pipe manufacturer, I was able to talk to people who know the profession; something I missed at other companies.

The Sonnette III fully met the requirements I had set, and with carefully selected sample sets the sounds are no different from the organs in the church. A Hauptwerk organ must reproduce the recordings with good loudspeakers in the right place. Then the pipe sounds of the church are realistically transferred into the living room.      Orgelmakerij Noorlander

Chamber organ

Pipe organ builders prefer to build the organs for churches. When an organ has to be built for a living room, this gives a large restriction in choosing the stops. Brilliant and loud sounds do not come into their own due to the lack of acoustics. What remains are flute sounds of the Stopped Diapason and the Chimney Flute.

For years I have tried to achieve the optimal sounds with a very sophisticated way of voicing, but due to the lack of acoustics, the limit has been reached quickly. Principal stops give the greatest limitation, often they can only be used as Octave two-foot. Mixtures and cymbals are impossible, reeds only in the form of a Regal with nasal sounds.

Hauptwerk brought a great improvement, the pipe sounds of the church organ can be transferred well to the living room and the samples also contain the acoustics of the church. Yet there is a difference from playing in a church. As an organ builder I played hundreds of organs in churches and then immediately the difference turns out when I play the organ in a living room. At the console in the church I hear the pipes at close range and in the same place I hear the reverberation in the church. When playing a Hauptwerk organ, the acoustics come from samples that are recorded at a great distance from the pipes. This can be heard in the living room; it sounds like the pipes are far away from the console where I play the organ. Not the best way to express something with sounds.

Convolution reverb

This disadvantage does not occur in conjunction with convolution reverb. I hear the pipes at a short distance and from the same place I experience the reverberation that appears around me. That is entirely consistent with the situation in the church. In Hauptwerk 5, the convolution reverb has been realized and that is a huge improvement.
see for operation: Convolution reverb

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

In a Hauptwerk organ, original pipe sounds sound with their reverberation in the church. Next to the Hauptwerk organ, my house pipe organ stands with well-voiced metal pipes and organists can compare both organs. Although the loudspeakers display the sounds, there is no difference with the sounds from the pipes. Without exception, the Hauptwerk organ is preferred. Now that Hauptwerk 5 has convolution reverberation, the disadvantages of a house pipe organ appear to be even clearer.

A pipe organ in a living room has no place for many registers, so only a limited disposition is possible. When a Hauptwerk organ is used as a house organ, there are hardly any restrictions. There are usually three keyboards and the same stops as a church organ. Most organists have therefore exchanged their pipe organ for a Hauptwerk organ. Now they can study the concerts at home under the same conditions as in the church. The Hauptwerk organ is the ideal house organ. The convolution reverberation adds the acoustics, such as the organist who belongs at the play table in a church.
