The organ of my church is a traditional organ, but for some months "they" did important work of "renovation" (no need !). The air is blowed with an electrical engine, but they connected the whole to... the speakers already connected on an electronic organ...
the organist found something sounded wrong wenn he played the great organ : his nightmares and earmares are finished : the engine burned last week doing much damage in the church...
Nice cockpit !
