This whole series is brilliant! I have been around organs for many years - my Dad is an organist - but have never seen one assembled on site. Fascinating! Well done to you all.
All those who think it's too quiet, should understand that you are hearing the sound as the organist hears it, not as it is in the rest of the building. It's not one we get to hear very often.
@amir2287 You need to move the microphone away from your mouth, or use a pop shield or wind shield.
