Disklavier

First of all, the physical parts of the pedal have to
be in adjustment; a hair of lost most motion when the
pedal is pressed and the solenoid gap set at the proper
clearance.  The half point was a number that a
technician had to calculate when Disklaviers first came
out. We don't have to do that anymore.  The dampers
should start away when the hammer is half way the
distance to the strings.  This calibration you do with
the Loud pedal only sets a value to be considered in
the piano tables condition calculation.  The number you
set makes a difference whether or not you get errors
when you run keyboard measurement.

The high C note you hear is only to let the person
doing the calibration hear a 1 second mark.  The
dampers are to shut off the strings at about 2 seconds.
You have to enter the number while the high C notes are
sounding; that's why they go on several times.  If the
number you choose is less than 40 or greater than 55,
you will probably get a pass number when doing the
keyboard measurement program.

The whole idea of the Loud pedal adjustment program is
to let the DKV play even when the pedal is out of
adjustment.  If the pedal goes too far out of
adjustment, then you will get error messages.  Since
your technician regularly visists your piano, there
should be no reason for you to do this yourself.
