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 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
