Which calls to mind (being an organist) that manufacturers of electronic 
organs (aka 'toasters') 
include all sorts of pipe organ artifacts/imperfections in their firmware: 
slight unsteadiness of 
wind, the attack and release transients that some pipes make, slow speech of 
pedal stops, deliberate 
detunings, swell shades slamming, and even the sound of the blower (in the 
basement, usually) 
starting up.
