Pipe organs need tuning several times a year. This digital instrument will need no regular adjustment and is unaffected by damp and cold which can upset the best of pipe organs.
Whilst it is difficult to forecast the life span of any organ before it needs rebuilding or upgrading, Wyvern has an excellent pedigree and has been building organs now for over half a century. They still look after many of these venerable instruments so we can at least consider this as a minimum life expectancy and would expect the potential life span to be extended still further. Modern digital organs are built with high quality electrical components. Unlike non custom-built organs where everything is operated from one circuit board, this system is a modular circuit design allowing easy exchange of boards, with integrated circuits which do not require delicate soldering techniques, but are plug-in and thus changeable on site.
The specification of the organ for the Grand Temple, if it were a pipe organ, would contain three thousand, three hundred and eighteen pipes! (Substantially more that at Freemasons' Hall Great Queen Street.) Each one of these virtual pipes can be voiced, regulated and tuned. Upon installation, the voicer will regulate, adjust the attack and release, and tune every note of every rank independently.
All external audio components are custom-built to the highest quality standards and all parts are guaranteed for ten years. Provision has been made for the manufacturers to visit in year ten of the guarantee period to ensure the organ is performing properly prior to the end of the warranty period.
