At times it may be desirable to add ranks of pipes to an existing pipe
organ. Of utmost importance, secondary only to proper selection of new
stops, is whether or not the existing organ chamber will accommodate additional
pipes without sacrificing the ability to service the instrument. In some
cases, the original builder prepared for future additions by leaving extra space
on the chest for specific ranks. A qualified builder, upon chamber
inspection, will know whether or not additions are practical.
An ideal time to add new pipework is during the process of rebuilding the pipe
organ. It is easier and more cost effective to provide switching, stop
tabs and associated wiring for new pipes at a time when the whole switching
system is upgraded. Also, it is sometimes possible to offer additional,
intelligent unification of existing pipework to increase versatility for the
recently became a popular product offered in the organ building industry as it
allows for the addition of electronically generated stops where there is
absolutely no additional space for pipework. However, additional space is
necessary for speakers for the electronic stops. The most practical
application for this type of installation is the very low pitched stops of 16'
or lower. A MIDI addition also allows for record/playback capability, a
great teaching tool and a method the organist may employ to step away from the
console to hear their registration from another place in the sanctuary.
