Piano 'detuning'

i once used a yamaha electric piano that sounded great if you slightly
detuned the left and right channels to give it a chorus effect.  i wonder,
though, if this was a result of the tuning or a stereo effect using the two
different speakers?  if it is the tuning, i would think the detuning would
have to be very equally "out of tune" to have that effect.


i have a friend who once tuned a very out of tune piano only to have the
customer complain that he had taken out all the vibrato.
