Description
This is for adjusting the speed of the FM modulation.
The Split control determines the extent to which the FM effect
is applied to high frequencies via a crossover. Turn to the right
to affect higher frequencies. It can be useful to eliminate noise
artifacts caused by FM of very high signals.
With high Split settings, the effect becomes more <gritty= and
crackling.
Contour determines the extent to which the input volume affects
the intensity of the effect.
Determines the amount of the FM effect.
