Noisy Action
I don't understand the fuss, either, unless it's really, really noisy.
When I recorded at Round Lake, NY, it was impossible to capture the kind of sound I wanted without getting action noise. The action has not been restored in over 100 years so it's nearly impossible to play it quietly--and when you hear it in real life, that's how it sounds! I also kept all the "nature sounds," such as crickets and locusts on the recording. Some people really liked that approach and a few really don't like it.
When I played at the Organ Historical Society convention last summer, one of the recitals was recorded live for the CD. During that recording, a bird came and sat on a tree right outside the window and sang its little heart out while I was playing. I hope they keep that on the recording, as I enjoyed that immensely! But I know some people would complain, and I just don't understand that.
