Sustain
The sustain feature lengthens the sound of the notes you play.

To turn the sustain feature on or off, press Sustain. When on, an icon will appear next to
SUSTAIN in the lower-right corner of the display.

The DSP (digital signal processor) feature adds a subtle reverb effect to the sound, creating a
more realistic ambiance.

the lower-right corner of the display.
