Roland ep-90/70 用户手册

Convenient Functions

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.
