Adjusting the Pitch of the Sound Master Tuning

Some Handy Functions

Transposing without Changing Your Keyboard Fingering (Key Transpose)

You can transpose the key of a performance without having to shift the position of your fingers on the keyboard.

This feature is called “Key Transpose.”

In situations such as when providing accompaniment to a song, using the Key Transpose function to match the singer’s vocal register lets you easily transpose the sounds without changing the score.

These settings remains in effect until you turn off the power.

For example if you want the E pitch to sound when you play the C key, you would hold down the [Variation] button and [Demo] button and press the E2 key.

Adjusting the Pitch of the Sound (Master Tuning)

In situations such as when playing ensemble with other instruments, you can tune the F-90’s reference pitch to the pitch of another instrument. The reference pitch generally refers to the pitch of the note that’s played when you finger the middle A key.

For a cleaner ensemble sound while performing with one or more other instruments, ensure that each instrument’s reference pitch is in tune with that of the other instruments.

This tuning of all the instruments to a reference pitch is called “master tuning.” You can set the reference pitch anywhere in a range of 415.3 Hz to 466.2 Hz.

When the instrument is turned on, the reference pitch is set to “440.0 Hz.”
