This adjusts the string resonance of the acoustic piano sound (the sympathetic vibrations of strings for previously played notes that occur when you 

play another note).
Higher settings will make the sympathetic vibration louder.

This adjusts sympathetic vibrations such as an acoustic piano’s key-off sound (the subtle sound that occurs when you release a note).
Higher settings will make the sympathetic vibration louder.
OFF, 1–10

This setting specifies what the transpose will affect. You can use the transpose to change the 

pitch of both the song and the keyboard, only the pitch of the song, or only the pitch of the 

keyboard.

You can change the pitch of the Tone 2 in Dual Play (p. 15) and Lower tone in Split Play (p. 16) an octave at a time.
Altering the pitch in one-octave units in this way is called “Octave Shift.”  

For example, you can raise the pitch of the Lower Tone to the same pitch of the Upper Tone in Split Play.
-2–0–+2 (octave)

You can choose whether to record as SMF or as audio.

You can also switch the recording mode by holding down the [ 

 ] (Rec) button and using the [–] [+] buttons.

SMF parts will be recorded separately. This allows you to re-record just a single part, or to overdub different parts.

The recording will be made as audio data. The recorded song can be used in your computer.

When you press the damper pedal during Dual play or Split play, the pedal effect is normally 

applied to both tones, but you can also select the tone to which the effect is to be applied.
