Hi Ric,
            Phasing gives almost the same aural effect as a false beat,
when listening to the unison.  However each individual string can sound
clean.  The fact that the harmonics are having their own little war because
of timing, is another different story. (GRIN)

Now here's some food for thought.  Unison sounds clean at ppp, but sounds
false at fff.  And yes it does happen.   It's usually the centre pin worn,
on one side of the bushing causing the hammer to twist at the beginning of
it's flight, inducing a phasing problem only on firm blows.

Heck it's a wonder these pianos ever work, and create such wonderful music.
