Chapter 9. Using the D Beam
FILTER
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.
SAW
: sawtooth wave
TRI
: triangle wave
SQR
: square wave
RND
: 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.
Parameter Value Explanation
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.
LPF
: frequencies below the Cutoff
BPF
: frequencies near the Cutoff
HPF
: frequencies above the cutoff
NOTCH
: 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.
