iCathedral Organ generates the sound of a lovely and color rich pipe organ of a real cathedral. All individual registers of such a pipe organ were recorded to resemble this sound as realistic as possible. You can fully adjust all individual organ registers to create your own sounds and save them as your personal sound presets. Or simply select one of the factory presets to play impressive organ sounds right fromt the start.

The sounds of this app were created by Kurt Ader, winner of the NAMM 2015 "Best Sound Designer of the Year" award.
