Roland HP 237 - Master Tuning; Reference Pitch Adjustment

Convenient Functions
Adjusting the Pitch of the
Sound-Master Tuning
In situations such as when playing in ensemble with other
instruments, you can adjust the HP 237’s reference pitch to
that of another instrument.
Middle A is generally used as the standard reference pitch
for tuning instruments.
When playing in ensemble with other instruments, set each
instrument to the same reference pitch to ensure that you
will be in tune with each other, This tuning of all the
instruments to a reference pitch is called “Master Tuning.”
The reference pitch can be set to any value from 415.3 Hz-
466.2 Hz.
“440.0 Hz” is the power-on default for the reference pitch.
Use the C4-D#4 notes to adjust the pitch.
