There is one Dutch mechanical action organ by Flentrop in the cathedral, the 1977 Great Organ of 3 manuals and 39 stops. A new Muller pipe organ was installed in 2021, combining an existing Aeolian Skinner pipe organ from St. Paul’s Episcopal Church in Richmond, Virginia with pipes from a Skinner organ at the Church of the Transfiguration in Cleveland, donated by the Diocese of Ohio. It has 4 manuals and 51 ranks.
