D Beam controller
The SP-555 provides a D Beam controller, which lets you
modify the sound in various ways by moving your hand
above it. You can choose one of three modes: [SYNTH]
(monophonic synthesizer), which lets you control the pitch by
your hand position; [FILTER], which lets you control the cutoff
frequency; and [TRIGGER], which lets you trigger the desired
pad.
The sensitivity of the D Beam controller will change depending
on the brightness of the environment. If it does not operate as
you expect, please readjust the sensitivity (D Beam Sens) as
follows.
While holding down [CANCEL], press either [SYNTH],
[FILTER], or [TRIGGER], and then use the CTRL 3 knob to adjust
the sensitivity. Turning the knob toward the right will increase
the sensitivity. When you’ve finished adjusting the sensitivity,
you can press [SAMPLING] to save the setting.
If you press [SYNTH] so the button is lit, you’ll be able to use
the SP-555 as a monophonic synthesizer whose pitch is
controlled by the position of your hand above the D Beam
controller. Moving your hand closer to the controller will
raise the pitch in steps of the scale you select. Use [SYNTH]
+ CTRL 2 to change the scale.
There’s also a built-in delay that can be used to produce a
variety of effects.
[SYNTH] will blink when you’re within the effective range of
the D Beam controller.

The effective range of the D Beam controller
The illustration below shows the effective range of the D
Beam controller. Moving your hand beyond this range
will not produce any effect.
The effective range of the D Beam controller will be
greatly reduced under strong, direct sunlight. Please be
aware of this when using the D Beam controller
outdoors.
