NP-30/YNP-25 Owner’s Manual 21

Transposition

The Transpose function makes it possible to shift the pitch of the entire keyboard up or down in

semitone intervals to facilitate playing in difﬁcult key signatures, and to let you easily match the

pitch of the keyboard to the range of a singer or other instruments. For example, if you set the

transposition amount to “+5,” playing key C produces pitch F. In this way, you can play a song as

though it were in C major, and the NP-30/YNP-25 will transpose it to the key of F.

Setting the amount of transposition

While holding down the [SONG

] and [GRAND PIANO] buttons, press one

of the F#2–F#3 keys to set the desired amount of transposition.

To transpose the pitch down (in semitone steps)

While holding down the [SONG

] and [GRAND PIANO] buttons, press any

key between F#2 and B2.

To transpose the pitch up (in semitone steps)

While holding down the [SONG

] and [GRAND PIANO] buttons, press any

key between C#3 and F#3.

To restore the normal pitch

While holding down the [SONG

] and [GRAND PIANO] buttons, press the

C3 key.

Fine tuning of the Pitch

You can ﬁne tune the pitch of the entire instrument. This function is useful when you play the NP-

30/YNP-25 along with other instruments or CD music.
