Þlters. Positive values raise the cutoff frequency of LOPAS2, while negative values lower it. If no
separation is applied, thereÕs a 24 dB per octave rolloff above the cutoff frequency.

Gated Lowpass Filter (LPGATE)
You may be familiar with gates as applied to effects like reverb, where the effect shuts off
abruptly after a speciÞed time. The gated lowpass Þlter produces a somewhat similar effect in
terms of the soundÕs amplitude. The ÞlterÕs cutoff frequency is controlled by the AMPENV.
When the AMPENV is at 100%, the cutoff frequency is high, so most of the partials are heard.
When the AMPENV decays or releases to 0%, the cutoff frequency is low, so only the lowest
partials are heard. YouÕll hear the distinct effect of the Þlter closing as the amplitude envelope
releases.
