Audio Damage Discord3 Upgrade - Manual (Page 13)

Above each LFO are two sliders which control how much the LFOs influence the delays and filters. The TIME
MOD slider causes the LFO to vary the delay time. Moving the slider to the left causes the LFO to decrease the
delay time, moving it to the right causes it to increase the delay time. The FILTER MOD slider causes the LFO
to vary the frequencies of the filters, as if you were dragging the filter control circle back and forth. Moving
the slider to the right causes the LFO to increase the filter frequencies, moving it to the left causes it to
decrease the filter frequencies.
