Effects List
Appendices
39: Radio Tuning
This effect reproduces the sound of an AM radio playing.
fig.MFX-39
40: Bit Rate Converter
By changing the bit count and sample rate, this effect recreates the
Lo-Fi (Low-Fidelity) sounds of the early digital samplers and similar
machines. After the Lo-Fi processor, a filter to change the tone is
arranged in series.

41: Pseudo Stereo
Spreads the components of the monaural input sound to left and
right, creating an artificial sense of stereo output.

Parameter
Value Description
Tuning #1
-50– +50 Adjusts the degree of noise that
occurs when tuning a radio.
Noise Level #2 0–127 Sets the noise level.
Frequency
Range #3
0–127 Sets the frequency response of
the radio.
Lowering the value worsens the
frequency characteristics, mak-
ing the sound appear to be com-
ing from a tiny radio speaker.
Balance DRY100:0WET–
DRY0:100WET
Volume balance between the di-
rect sound (DRY) and the effect
sound (WET)
Parameter
Value Description
Pre Filter Sw
OFF, ON This is the switch of the filter
placed before the Lo-Fi process-
ing
Sample Rate 1/1, 1/2, 1/4,
1/8, 1/16, 1/32
Sets the fraction of current sam-
pling rates to be used for pro-
cessing.
Bit Down 0–15 This setting is for reducing the
bit count.
Post Filter Sw OFF, ON This is the switch of the filter
placed after the Lo-Fi process-
ing.
Balance DRY100:0WET–
DRY0:100WET
Volume balance between the di-
rect sound (DRY) and the effect
sound (WET)

Filter Type
THRU, LPF,
BPF, HPF,
NOTCH
Type of filter
THRU: no filter is used
LPF: Passes frequencies below
the Cutoff.
BPF: Passes frequencies near the
Cutoff.
HPF: Passes frequencies above
the Cutoff.
NOTCH: Passes frequencies
other than those near the Cutoff.
Filter Slope -12, -24 dB/O Filter’s attenuation slope
-24 dB per octave: steep
-12 dB per octave: gentle
Filter Cutoff 0–127 Cutoff frequency of the filter
The closer to zero it is set, the
lower the cutoff frequency be-
comes; set it closer to 127, and
the cutoff frequency becomes
higher.
Filter Reso-
nance
0–127 Resonance level of the filter
Raising the setting increases res-
onance near the cutoff frequen-
cy, giving the sound a special
characteristic.
Filter Gain 0– +24 dB Compensates for the volume
dropped in the cut frequency
range with some filters.
The level of compensation in-
creases as the value is increased,
and raise the volume.
