Roland LX-15 用户手册

“Transpose” means to shift the pitches of songs and the keyboard.
The Transpose function makes it easy to do the following.

•  You can use unchanged fingering to accompany a singer who is singing in a key different than the original music.
•  A song written in a difficult key with numerous sharps ( ) or flats ( ) can be performed in a key that’s easier for you to play.
•  Notation of a transposing instrument such as trumpet or sax can be played as written, while hearing the transposed pitches.

For example if the song is written in E major but you want to play it using the fingering of the key of C major, you would set Transpose to “4.”

If you play C E G   It will sound E G  B

With the factory settings, both the song and the keyboard will be transposed. If you want to transpose only the keyboard or only the song, make 

the appropriate setting as described in “Specifying What the Transpose will Affect (Transpose Mode)” (p. 45).

The [Transpose] button will light.

The display will indicate the amount of transposition.

-6–0–5 (semitone units)
(default: 1)

Positive (+) values raise the pitch in semitone steps, and negative (-) values lower the 

pitch in semitone steps.

You can also specify this value by holding down the [Transpose] button and playing the note that is the tonic of the key to which you want to 

transpose.

*  If you select a different song, the transposition setting will be canceled.

The [Transpose] button will go out.
