Lo-fi
Degrades the tonal character.
Parameter Value Explanation
PRE FILT 1‒6 Sets the type of pre-filter (the filter that the sound
passes through before effects are applied).
LOFI TYPE 1‒9 Larger settings cause more tonal degradation.
TONE -100‒100 Sets the tone. Larger settings emphasize the high-
frequency range. Smaller settings emphasize the
low-frequency range.
CUTOFF 200, 250, 315, 400, 500, 630, 800, 1000,
1250, 1600, 2000, 2500, 3150, 4000,
5000, 6300, 8000 (Hz) Sets the frequency range in which the post-filter
(the filter that the sound passes through after
effects are applied) works.
BALANCE 100-0‒0-100 Adjusts the volume balance between dry (the
original sound) and effect sound.
LEVEL 0‒100 Adjusts the volume of the effect sound.
This effect may output a very loud sound, depending on how the parameters are set. Use caution not to raise the
values too much.
