Organs are unique – that is well known. The Wanderer organ by concert organist Paolo Oreni is something even more special: It is the first transportable concert organ! Transportable chest organs or even digital instruments are not uncommon, but the Wanderer organ, on the other hand, is a stately pipe organ! With the help of the so-called multiplex principle, a total of 43 stops are obtained from 12 unit ranks, which can be controlled from a three-manual console. The various pipes are distributed over individual mobile modules and can therefore be positioned independently of each other at the respective installation site and easily transported.
