Simultaneously hold down the PLAY/EDIT button and press the
REVERB TYPE button (for Reverb), or the CHORUS TYPE button (for
Chorus).
V Select the desired Reverb (or Chorus) Type.
Use the VALUE buttons. For a list of the available Reverb Types, see
page 57. For a list of the available Chorus Types, see page 58.

Once you've selected an Reverb or Chorus Type to your satisfaction,
you can re-adjust the effect level for the selected Part (and other

Using the Variation Effects

The Variation effect section provides a wealth of additional effects,
with which you can enhance or radically change the sound of the
Voices.
Variation can be applied to all Parts (just as with Reverb and Chorus),
or to a single selected Part. (For more information on the Variation
effect, see page 59.)
