hmm, I see I have to advertise my home town;)
The fabulous woodcarving decoration of the organ is the work of the Bernardine fathers. The Leżajsk organ consists in fact of three separate instruments. In the side-naves, there are smaller instruments, and the largest one is in the main nave. The organ has mechanical controls (tracker system) and 75 voices altogether. It is equipped with effects, such as cuckoo, drum (tyman), birds, horribile. The organ has full 32' voice. The four cases of the main organ, connected with the choir decoration, constitute the monumental façade, which fills the west wall of the basilica, reaching the vault. The main organ is 15 m high and 7.5 m wide, and it has an inseparable connection with the instruments in the side-naves. This is why three organists can play simultaneously.
