Filter Gain
An additional modulation destina-
tion of LFO 1. Here the input level
of the filter section is modulated
(and thus the subsequent satura-
tion level). The effect of a FILT GAIN
modulation is a periodic change in
the saturation level which is linked
to a corresponding tremolo (peri-
odic change in volume). If the sig-
nal is not saturated in any manner,
then the only audible result is a
tremolo effect. We purposely
placed the modulation point in
front of the filter section in the sig-
nal chain. This means that the dis-
tortion amount – i.e. the intensity
of the effect – is also modulated
when you activate SATURATION.
Furthermore, you can use fast LFO
oscillations to generate brief
impulses (transients) in the oscilla-
tor signal that excite the resonant
tion of LFO 1. Here the input level
