For over eighteen years the most stable and extensive resource on the Internet for pipe and electronic organs
The hub of this site is the Complete Articles page which gives you instant access to many detailed articles dealing with numerous technical aspects of both pipe and electronic organs. Use the Google search box below to quickly identify areas of interest. 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?

!! NEW ARTICLE !! - A digital simulation of the organ at Malvern Priory
This article describes a digital simulation of the large and beautiful Rushworth & Dreaper organ of 1927 at Great Malvern Priory, England, though it is unusual in that the sound samples were recorded nearly forty years ago. At that time there was no thought of using them to recreate the sound of the organ because the necessary technology was not widely available, and instead they have been used in various studies of the physics of organ pipes. However the advent of the virtual pipe organ in more recent times means that the sample set can now be used to simulate the instrument as it sounded then (1979), which is significant because the organ has been rebuilt subsequently with consequential changes in its aural character. The simulation therefore retains the aural flavour and playing experience of an untouched English romantic instrument, Edwardian in concept, whose sounds have been lost to some extent. Some sound files are included.
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. Playing time 1 hour 35 mins approx.
