fig.MFX-59
Simulates a sound recorded on an analog record and played back on a
record player. This effect also simulates the various types of noise that are
typical of a record, and even the rotational irregularities of an old turntable.

58: LOFI RADIO
Parameter Value Description
LoFi Type 1–9
Degrades the sound quality. The sound qual-
ity grows poorer as this value is increased.
Filter Type
OFF, LPF,
HPF
Type of filter
OFF: no filter is used
LPF: cuts the frequency range above the
Cutoff
HPF: cuts the frequency range below the
Cutoff
Filter Cutoff 200–8000 Hz Basic frequency of the Post Filter
Radio

Balance D100:0W–D0:100W
