Chapter 9. Using the D Beam

 

This lets you use the D Beam to control a built-in filter that features an extremely steep slope.

In this screen you can view the D Beam value in graphical form. (Vertical axis: D Beam value; Horizontal axis: 
time)

 screen.

Vibrato Depth

0–127

Specifies the depth of vibrato (an effect that uses an LFO to cyclically vary the 
pitch of the oscillator).

LFO Wave

0–127

An LFO (Low Frequency Oscillator) is used to apply various types of modula-
tion (cyclic change) to the tone or pitch. You can select one of the following LFO 
waveforms.

 

: sawtooth wave

 

: triangle 

wave

 

: square 

wave

 

:  randomly changing waveform

LFO Rate

0–127

Specifies the speed of modulation.

 

PORTAMENT

 

 

TIME

0–100

Specifies the time over which Portamento (a function that creates smooth pitch 
transitions between synthesizer notes) will vary the pitch. With higher settings, 
the pitch change will take longer.

 

Cutoff Low

0–127

Specifies the lower frequency limit for the D Beam controller.

Cutoff High

0–127

Specifies the upper frequency limit for the D Beam controller.

Resonance

0–127

Specifies the resonance level of the filter. Raising this value will boost the sound in the 
region of the cutoff frequency.

Type

LPF,
BPF,
HPF,
NOTCH

Specifies the type of filter. Each type of filter will pass the following frequencies.

 

: 

frequencies below the Cutoff

 

: 

frequencies near the Cutoff

 

: 

frequencies above the cutoff

 

:  frequencies other than at the Cutoff

Slope

-12dB,
-24dB,
-36dB

Specifies the steepness of the filter (expressed as the amount of attenuation per octave).

Gain

0–+12dB

Adjusts the amount of boost for the filter output.
