For over 21 years the most stable and extensive resource on the internet for pipe and electronic organs
As this site is now into its third decade it's not surprising that it has grown into quite a big place. So if you are new to it, you might first want to hit the Sitemap button in the navigation bar above to get a quick idea of the general layout. Maybe try skimming the material revealed by the other buttons as well. Then, when you feel ready to dive in more deeply, the main hub of the site is the Complete Articles page which gives you instant access to well over 100 detailed articles dealing with technical aspects of both pipe and electronic organs. You can also use the search box below to quickly identify articles of interest. And the navigation bar stays with you wherever you are, so you can always find a way out of any labyrinth you might feel trapped in - if you are desperate just hit the Home button and you'll get back to here. While browsing, why not also listen to over 4Ĺ hours of music played on the three manual organ below and the Prog Organ virtual pipe organ here?
So thank you for visiting, and do enjoy!

It's a YouTube demo of my "Trendline Synthesis" technique for voicing digital organs which requires only four numbers to create any type of organ tone, be it flute, diapason, string or reed. In practice the numbers, and thus the sounds, are computer-generated in real time simply by adjusting four of the MIDI Controller knobs found on many keyboards. The technique reduces a hitherto difficult and complex operation - voicing synthetically-generated waveform samples - to one where you can converge rapidly towards the end result literally in a few seconds rather than many minutes or even hours. Therefore it mirrors the speed with which an experienced pipe organ voicer can get the desired timbre or tone colour from an organ pipe. This sets the technique well apart from traditional methods for generating synthetic waveforms such as additive synthesis or physical modelling, which involve a fatiguing and time consuming process requiring vastly more parameters to be adjusted.
The picture above is of a test rig used for experiments on pipe organ valves, such as those described in the articles entitled Calculating Pallet Size, Touch Relief in Mechanical Actions and Response Speed of Electric Actions. These can also be accessed from the Complete Articles page where summaries are also available.
This electronic organ is a dual purpose instrument containing both "straight" and "theatre" voices, designed and made by the author. It is tuned to the author's Dorset Temperament with the addition of some impure octaves as described in Keyboard Temperaments with Impure Octaves. A full specification can be downloaded here (PDF file, 717 kB).
The things they say:
These recordings span some years and they were made in various rooms and auditoria. The older tracks were made using analogue equipment and some were recorded acoustically using microphones, hence the occasional noises due to piston thuds and page turns, etc. Other tracks were captured electrically. All are of real players performing in real time - no synthetic MIDI 'performances' here. I have not got round yet to normalising the volume settings of all the tracks so they are compatible with each other, therefore you might wish to adjust the volume between tracks depending on which ones you select. Do not be alarmed if some tracks appear to start with an excessive noise level - this simply means they were recorded at a higher level than others. Just turn the volume down to suit. In any case, it is a wise precaution to always begin playing each track at a low level to protect your audio equipment and your ears from unexpectedly high signal levels when the music begins. Although the instrument has 13 ranks of theatre organ voices in addition to its 'straight' sounds (see specification), copyright considerations preclude the inclusion of much theatre-style music here.
