Performance Functions and Effects
Assigning a function to the D Beam
controller
1. Press and hold [ASSIGNABLE 1] or [ASSIGNABLE 2].
The D BEAM screen will appear.
2. Use [ ] [ ] to select a parameter.
3. Turn the VALUE dial to select the desired D Beam function.
4. When you’ve finished making settings, press [EXIT].
The Main screen will appear.
These settings are system parameters (p. 46).
Functions that can be assigned
Osc2 & Sync
Osc 2
Waveform
(same as Osc 1)
Osc 2 Pulse
Width
Osc 2
Coarse
Tune
Osc 2 Fine
Tune
Osc 2 Level 0–127 Adjust the level.
Osc Sync
Switch
OFF, ON
Turning this switch on
produces a complex sound
with many harmonics.
This is effective when the
OSC1 pitch is higher than the
OSC2 pitch.
Filter
Filter Type
OFF, LPF,
BPF, HPF,
PKG
Type of filter
OFF : No filter is used.
LPF : Low Pass Filter. This
reduces the volume of all
frequencies above the cutoff
frequency (Cutoff) in order to
round off, or un-brighten the
sound.
BPF : Band Pass Filter. This
leaves only the frequencies in
the region of the cutoff
frequency, and cuts the rest.
HPF : High Pass Filter. This cuts
the frequencies in the region
below the cutoff frequency.
PKG : Peaking Filter. This
emphasizes the frequencies in
the region of the cutoff
frequency.
Cutoff 0–127
Frequency at which the filter
begins to have an effect on the
waveform’s frequency
components
Resonance 0–127
Emphasizes the portion of the
sound in the region of the
cutoff frequency, adding
character to the sound.
* Excessively high settings can
produce oscillation, causing
the sound to distort.
Parameter Value Explanation
LFO
LFO Rate 0–127 Modulation speed of the LFO
LFO Osc 1
Pitch Depth
-63– +63
Depth to which the LFO will
modulate the Osc 1/2 pitch
LFO Osc 2
Pitch Depth
LFO Osc 1
Pulse
Width
Depth
-63– +63
Depth to which the LFO will
modulate the pulse width of the
Osc 1/2 waveform
* The Pulse Width is
activated when “SQR” is
selected with Osc 1/2
waveform.

Explanation
DRUM
ROLL
A snare drum roll will continue as long as your
hand is positioned over the D Beam. Move
your hand closer to increase the volume, and
move your hand rapidly away to play a
cymbal.
CHIMES
Chimes will sound when you position your
hand above the D Beam. The volume is greater
when you move your hand more rapidly.
BUBBLE
The sound of bubbles will continue as long as
your hand is positioned above the D Beam. The
volume will increase as you move your hand
closer.
