Applying various effects to the sound
2. While playing the keyboard to produce sound, place your hand over the D
Beam, and slowly move it up and down.
An effect will be applied to the sound, depending on the function that is assigned to
the D Beam controller.
3. To turn off the D Beam controller, press the button once again to turn it off.

Effects that can be used with the D Beam controller
SOLO SYNTH
This lets you generate passages that sound as if you are playing the keyboard
rapidly. For example, if you hold down the four notes C, D, E, and G with your right
hand and move your left hand over the D Beam, a phrase such as “C D E G C D E G
...” will be repeated.
For example, you can use the D Beam to play a synth solo on a synth-lead type
sound, and hold chords using a long, sustaining sound to create the impression of
harp playing.
The chord memory function also provides a chord set that contain notes of a specific
scale and is designed for use with this function (16. Scale Set).
ACTIVE EXPRESS (Active Expression)
You can use the D Beam as an Active Expression function. If you assign the Active
Expression function to a patch that consists of dual tones (a patch whose
[KEYMODE] is set to “DUAL”), you can create tonal changes for greater
expressiveness, and to emphasize the forte passages in your playing.
The patches suitable for active expression have “AEx” in their names.
The usable range of the D Beam controller
The following diagram shows the usable range of the D Beam controller. Waving
your hand outside this range will produce no effect.
fig.q05-14
Either [SOLO SYNTH], [ACTIVE EXPRESS], or
[ASSIGNABLE] will blink while the D Beam controller is
responding. When your hand leaves the usable range of the D
Beam controller, the button will stop blinking, and will
remain lit.
* The sensitivity of the D Beam controller will change depending
on the amount of light in the vicinity of the unit. If it does not
function as you expect, adjust the sensitivity as appropriate for
the brightness of your location (p. 38). Also, the usable range of
the D Beam controller will be considerably reduced when used
under strong, direct sunlight. Please be aware of this when using
the D Beam controller outside.
The explanations of each
type in this manual are for
when the D Beam Polarity
is set to “NORMAL” (p. 38).
With [SOLO SYNTH]
switched on, pressing the
keyboard alone will not
result in the production of
sound. You need to move
your hand over the D Beam
while you hold down keys.
If the Active Expression
Switch (p. 57) of the patch
is turned OFF, this will be
conventional expression
(volume change).
You will hear no sound if
you play the keyboard
when Active Expression
has set the volume to 0.
