Oh no wonder my little Korg DT-1 kept jumping from F to A ! !   Tomorrow I will feed
it into Tunelab.  (hehheh)   Of course I don't have "perfect pitch" or long ago
would have recognized the dial tone as A or at least an F--A major triad.  Yes
comparing with  my Juno 60 synth (antique already?)  it sounds closer to  F--A than
just A440 here in the mid mid west of South Dakota.
