Using the D Beam Controller to Modify the Sound

By positioning your hand above the D Beam controller located on the front panel, you can easily modify the sound or produce sound effects.
This is a useful way to make your live performance even more expressive.

1. Press either the D Beam [Pitch], [Filter], or [Volume] button, so its indicator is lit.

Pressing the button cycles the illumination status of the indicator between lit (red), lit (green), and unlit. Switch the color of the button’s indicator to

select the desired effect.

Effective range of the D Beam controller

The illustration at right shows the effective range of the D Beam controller. Moving your hand outside this range will

not produce any effect.
The effective range of the D Beam controller will be drastically decreased under strong direct sunlight. Please be

aware of this when using the D Beam controller outdoors.

MEMO

The sensitivity of the D Beam controller will vary according to the brightness of its surroundings. If it does not

operate as you expect, you can readjust the sensitivity. Increasing the D Beam sensitivity value (p. 94) will make it

more sensitive.
