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.

Description
This is the switch of the filter
placed before the Lo-Fi process-
ing
Sets the fraction of current sam-
pling rates to be used for pro-
cessing.
This setting is for reducing the
bit count.
This is the switch of the filter
placed after the Lo-Fi process-
ing.
Volume balance between the di-
rect sound (DRY) and the effect
sound (WET)
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.

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.
Resonance level of the filter
Raising the setting increases res-
onance near the cutoff frequen-
cy, giving the sound a special
characteristic.
Parameter Value
Filter Gain 0– +24 dB
41: Pseudo Stereo
Spreads the components of the monaural input sound to left and
right, creating an artificial sense of stereo output.

Effects List
Description
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.
