Plate effects were originally gen-
erated by large, thin sheets of metal
suspended upright under tension
on springs. Transducers attached
to the plate would transmit a signal
which would, in turn, vibrate the
plate. Because the plate provided
a denser medium than air, sounds
broadcast through it would seem
to be ocurring in a large open
space.
The Plate effect synthesizes the
sound of metal plates, with high
initial diffusion and a relatively
bright, colored sound. This effect
is designed to be heard as part of
the music, mellowing and thicken-
ing the initial sound. It is a popular
choice for enhancing popular mu-
sic, particularly percussion.

Spred 0-255 Sustain of reverberation after initial build up
Gate is a reverb effect with a
fairly constant sound and no de-
cay until the reverb is cut off
abruptly. This effect works well on
percussion — particularly on snare
and toms, but be sure to experi-
ment with other sound sources as
well.
The Mix, P Dly and Rt HC pa-
rameters are very important in this
effect, allowing you to create any-
thing from an enhancement or
subtle thickening, to a solid wall of
reverb.
