Trinity Organ
Trinity Church has three organs. In the rear balcony of the nave is a mechanical-action organ built for Trinity by Casavant Frêres, Saint-Hyacinthe, Québec, in 1978. It has four manuals, 42 stops, and 64 ranks and consists of a Grand Orgue, Positif, Récit, Pédale, and a solo trompette en chamade. The Casavant also includes four digital electronic Pédale stops by Bob Walker of Zionsville, Pennsylvania. In addition to the gallery organ, there is a one-manual, four-stop movable continuo "chest" organ, also by Casavant. The organ in the chancel of the church is a Walker digital organ, custom-built for Trinity Church by the Walker Technical Company in 2000. Its console is usually at the chancel entrance of the Michael Chapel but can be moved if needed. Its comprehensive French design includes three manuals, a full pedal board, 63 stops, and 78 equivalent ranks. A set of nave speakers aids congregational singing.
