Adjusting the Pitch of the
Sound—Master Tuning
In situations such as when playing in ensemble with other
instruments, you can adjust the ep-90/70’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.”
“440.0 Hz” is the power-on default for the reference pitch.
MEMO
By holding down the [Demo] and [Sound] buttons, and pressing
the corresponding note, you can hear a reference tone (Middle A) as
you adjust the pitch.
