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

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

The level of compensation in-
creases as the value is increased,
