This organ has 124 stops, 4 manuals and pedals, 6718 pipes of different size and material that are placed on 26 wind chests. The pipes are made of different woods: pine, fir, maple, oak, beech, and pear, as well as of different metal alloys, like tin and lead alloys of varying proportions. Pipes also vary as to their size - the longest being about 10 m and the shortest only 13 mm long. The organ has two consoles that are located in two galleries. The big console in the upper gallery has four manuals. On both sides of the manuals there are stop shutters. The small console is in the lower gallery and its keyboard duplicates the fourth manual of the big console.
