The Conference Center organ is heard at the church’s semi-annual General Conference, and at other performances throughout the year.
The organ is about two-thirds the size of the Salt Lake Tabernacle organ in number of pipes (the Conference Center Organ has 7,708 pipes in 130 ranks, while the Tabernacle Organ has 11,623 pipes in 206 ranks). Former Tabernacle organist John Longhurst described it as a "project of immense proportion."
Longhurst described his reaction to the announcement in 1996 of the building of the Conference Center and his involvement in the building of the organ as follows:
"Needless to say, [the announcement of the Conference Center] made it difficult for me to concentrate on the rest of the Conference session. I could only begin to envision a space like President Hinckley had described. I assumed that an organ would be necessary in that building and immediately began considering what that instrument might be. By this time Robert Cundick had retired, and Richard Elliott was now on staff. As it turned out, all of the experience previously gained working on the other Temple Square organs (and particularly the Tabernacle organ, which we had thought of as a culmination) we now viewed as preparation for what was to follow. President Hinckley's announcement that Easter morning began a journey for us organists that would not conclude for seven years, when the Conference Center's Schoenstein & Co. organ was finally declared finished, just in time for the A.G.O. bi-regional convention held in Salt Lake City in the summer of 2003."
The organ includes a number of so-called "mechanical aids," though these are actually electronic. According to principal Tabernacle organist Dr. Richard Elliott (organist), these include a "built-in recorder," which allows organists to play a performance, and then go out into the auditorium and listen as the organ's computer replays the piece by physically sounding the pipes.
