Conversely, [Lute] is a distinctive sound with a rapid decay, and is used by itself. If you press the [Organ I] or [Organ II] button, the harpsichord sound will be switched off, and you'll change to an organ sound.

If you want to store a different sound and use the pedal to switch sounds, hold down [Function] once again and press [Organ II] to make the [Organ II] indicator light green.
