A Plate reverb is a large, thin sheet of
metal suspended upright under tension on
springs. Transducers attached to the plate
transmit a signal that makes the plate
vibrate, causing sounds to appear to be
occurring in a large, open space. The
Plates in the MX200 model the sound of
metal plates with high initial diffusion and a
relatively bright, colored sound. Plate
reverbs are designed to be heard as part
of the music, mellowing and thickening the
initial sound. Plate reverbs are often used
to enhance popular music, particularly per-
cussion.
Room produces an excellent simulation of
a very small room which is useful for dialog
and voiceover applications. Room is also
practical when used judiciously for fatten-
ing up high energy signals like electric gui-
tar amp recordings.
Historically, recording studio chambers
were oddly shaped rooms with a loud-
speaker and set of microphones to collect
ambience in various parts of the room.
Chamber programs produce even, rela-
tively dimensionless reverberation with little
color change as sound decays. The initial
diffusion is similar to the Hall programs.
However, the sense of size and space is
much less obvious. This characteristic,
coupled with the low color of the decay tail,
makes these programs useful on a wide
range of material - especially the spoken
voice, to which Chamber programs add a
noticeable increase in loudness with low
color.
Gated reverb is created by feeding a
reverb, such as a metal plate, through a
gate device. Decay Time is set to instant,
while Hold Time varies duration and sound.
The Gated reverb provides a fairly con-
stant sound with no decay until the reverb
is cut off abruptly. This program works well
on percussion — particularly on snare and
toms; be sure to experiment with other
sound sources as well.
Reverse reverb works in the opposite
fashion from normal reverb. Whereas a
normal reverb has the loudest series of
reflections heard first that then become
quieter over time, the Reverse reverb has
the softest reflections (essentially the tail of
the reverb) heard first, and then grows
louder over time until they abruptly cut off.
Ambience is used to simulate the effect of
a small or medium sized room without
noticeable decay. It is often used for voice,
guitar or percussion.
Much like Room reverb, Studio produces
an excellent simulation of smaller, well-
controlled acoustic spaces, characteristic
of the main performance areas in recording
studios. Studio is also useful with dialog
and voiceover applications as well as indi-
vidual instrument and electric guitar tracks.
