• Welcome to the Pipe Organ Forum! This is a part of the open community Magle International Music Forums focused on pipe organs (also known as "church organs"), organists, organ music and related topics.

    This forum is intended to be a friendly place where technically advanced organists and beginners (or even non-organists) can feel comfortable having discussions and asking questions. We learn by reading and asking questions, and it is hoped that the beginners (or non-organists) will feel free to ask even the simplest questions, and that the more advanced organists will patiently answer these questions. On the other hand, we encourage complex, technical discussions of technique, music, organ-building, etc. The opinions and observations of a diverse group of people from around the world should prove to be interesting and stimulating to all of us.

    As pipe organ discussions can sometimes become lively, it should be pointed out that this is an open forum. Statements made here are the opinion of the poster, and not necessarily that of the forum itself, its administrator, or its moderators.

Norden Schnitger VPO Emulation

Hi all,

When I was about 15 years of age, my local church was rebuilt, larger and grander, and in it was installed a small tracker 2-manuals pipe organ. I “learnt” to play it, to the point that I could play occasionally for church services, and spent the next 65 years hoping that I would hear from a pipe organ substitute sounds which really did remind me of playing that instrument. I was always disappointed. Now, much older at 81 years, I have become reconciled to the conclusion that the expectation was unrealistic – if or no other reason than that loudspeakers project sound in a very different way to how real pipes do it. But that doesn’t mean that Virtual Pipe Organs, for example, cannot deliver a musically satisfying result, if we are able to readjust our goals slightly.

My VPO program of choice is jOrgan, and I briefly state my reasons in the website I created for jOrgan, called jOrgan Discovery (https://jorgan.info). Over the past ten years I have learnt how to use jOrgan and how to create my own VPO’s for it (called “dispositions”). I began using synthesized samples, but moved on to using recorded samples, most of which I made myself of organs I recorded in the Sydney N.S.W. area.

About 18 months ago, I came upon a YouTube video where the organist at the Arp Schnitger organ in the German city of Norden demonstrated its main sounds. I knew that it was possible to gain enough information from that video to enable me to “impose” the Norden sound upon recorded samples I had made of a neo-baroque organ installed in a Sydney church in the 1980’s, as I had already done the same sort of thing with the recordings made of a well-known Sydney pipe organ. They were made a few months before that organ and its church were destroyed in a terrible fire. A jOrgan VPO based upon my work on the lost Sydney organ now graces the church where my organ journey started all those years ago.

In this post I am sharing with you an MP3 recording of the first variation of BWV 767 (O Gott, du frommer Gott), using the HW Rohrfloit 8 and the RP Principal 8 of my Norden Schnitger VPO. You do of course need a better audio system than what comes with the computer, to do it justice. Secondly, there is a very short MP3 playing the first few notes of the video’s HW Principal 8 demonstration, followed by the same notes being played on my VPO and using the same stop, but without the reverberation of the building. I could have used excellent somputer-generated reverb for this, but did not do so. I think you will be surprised at how successful my method has been. (Yes, one of the “real” notes has a chiff, but I did not try to reproduce it with this stop.)

If there is interest, I can share with you other examples of the sound of this VPO.
