Gated Reverbs - A true gated reverb is simply a reverb followed by a gate. In the GSP-2101
Artist, this combination is emulated in a single Module. Gates usually include adjustable thresh-
olds to set the point at which the reverberations will be gated (cut off). In fig. 3-7,you can see
that reverberations occurring at a level below the gate threshold cutoff point are muted. This
causes the reverb to decay for a specific amount of time (determined by the gate time), then it is
cut off abruptly.
Gated reverbs are most commonly used on percussion, but there are other ways to employ the
unique sound they produce. For instance, using a BUILD envelope shape, a reverse reverb effect
can be accomplished. Rather than decaying out to be cut off by the gate, a reverse gate builds for
a specific amount of time, and is cut off by the gate. Reverse envelopes are similar in sound to
playing a record backwards. Fig. 3-8 shows how it works.

The accent point shown in the diagram allows placement of the actual sound, either before or
after the gate has cut off the reverberation.
The GSP-2101 Artist offers three different envelope shapes in the gated reverb Modules: RAMP
DOWN, FLAT, and RAMP UP. RAMP DOWN is a standard gated reverb envelope, with a lin-
ear decay to the cutoff point. In most applications, the RAMP DOWN envelope doesn't need
an accent point, although it can produce some interesting unnatural sounds. In instances where
an accent point is not needed, simply turn down the left and right REVERB ACCENT LVL
parameters.
Using a FLAT envelope shape, the reverberation neither decays nor builds, but remains at a
constant level for a specified amount of time (determined by the setting of DECAY TIME). This
shape is particularly useful for short, percussive sounds.
RAMP UP allows creation of dramatic reverse gate reverb effects, with placement of the accent
point permitted within 50 milliseconds before or after the end of DECAY TIME. Gated reverbs
can be found in the <REVERB> library, and their parameters are as follows:
Effect On / Off
: Turns the Module on or off. When the Module is turned off, its
Parameters are not displayed and signal will not continue to pass through the module.
To see the Parameters, you must turn the Module on.
Pre-Delay Time
: Sets the amount of time before the reverberations are heard.
Adjustable from 0 to 100 milliseconds.
Decay Time
: Controls the amount of time before the gate cuts off the reverberations.
Variable from 50 to 1000 milliseconds.
Envelope Shape
: Sets the shape of the reverberation envelope (DECAY, FLAT, or
BUILD).
