Gating
Of all the different reverb types, only two types do not provide gating parameters
(ÒReverseÓ and ÒNonlinearÓ). Gating is the process which abruptly cuts off the
reverbÕs decay for a more ÒchoppyÓ sound. This effect was very popular on drums in
the 80s because it makes them sound HUGE. It is achieved by dropping the level of
the signal very rapidly after the initial attack making a short, sharp sound.
There are four gating parameters available in most of the reverb types. These
include: Gate Trigger Source, Hold Time, Gate Release Time and Gate Level. The
Trigger Source can be either the Left or Right inputs, or both. Or this can be set to
ÒOFFÓ when you do not wish to use the gating effect. The Hold Time determines
how long the gate will be held open before it begins to turn off; this can be set from
10 to 500 ms. The rate at which it closes is determined by the Gate Release Time,
which can be set from 0 to 500 ms. The Gate Level controls the level of the reverb
signal after the gate closes. In other words, if the Gate Level is set to 99, then no
reverb will sound after the gate turns it off. If the Gate Level is set to 50, then some
reverb signal will still be present even after the gate turns off the main reverb
signal.
