Roland LX-15 用户手册

An audio recording of a song, or a song from a digital audio player connected to the Input jacks can be transposed to make it play back in a different 

key. You can play the keyboard while listening to the transposed sound.

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.

•  Transposition will apply to the selected audio file and also to the sound of the digital audio player connected to the Input jacks.
•  You can also use the Function mode’s “Audio Transpose” setting to change the amount of transposition (p. 45).

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

The [Transpose] button will go out.

This function lets you minimize the melody of a song played back by a digital audio player connected to the Input jacks, allowing you to play the 

melody yourself on the keyboard, or use commercially available piano instruction CDs for piano lessons.

The [Right] button will go out, and the melody sound will be minimized.

•  Center Cancel will apply both to the selected audio file and to the digital audio player that’s connected to the Input jacks.
•  You can also use the Function mode’s “Center Cancel” setting to turn this off (p. 45).

*  The Center Cancel setting will turn off if you select a different song.

The [Right] button will light.
