This Composite took meticulous detailing and voicing, and this owes to its huge size and the acoustics which are extremely long, going even past 8 seconds. It is not intended to be an exact replica of the cologne cathedral organ, but to give a resemblance by its exact stoplist and similiar organs. The sample set loaded in 14 bit requires about 7 GB, and for further quality it needs more, so the advanced version is recommended.
