FEEDBACK Controls the amount of feed-
back in the Chorus. On the chorus, FEED-
BACK lets you boost specific frequencies
in the delayed signal to create a flanger
effect. The FEEDBACK parameter is bipo-
lar; positive or negative feedback values
let you dial in different flanger charac-
teristics.

s The following parameters are only
available when you're working with
REVERB algorithms.
REVERB DECAY TIME This parameter
determines the decay time for the given
room.
In a real room, the sound bounces off
several walls and covers a considerable
distance before it reaches your ear. The
longer the sound travels and the more
often it is reflected, the softer it will
become. You could say that this effect is
comparable to a pool or billiards ball
that travels a greater distance, bouncing
of several cushioned edges along the
way. This friction depletes energy and
causes the pool ball to slow down. The
sound's loss of energy is controlled via
DECAY TIME. When you dial in the mini-
mum value, the decay time is extremely
short so you'll hear just the early reflec-
tions. At the peak value, no energy is lost
so the decay time is infinite, which is of
course physically impossible in the real
world.

[XP] REVERB DAMPING This parameter
controls high-frequency attenuation of
the room's fading reflections.
In a real room, walls don't reflect high
frequencies as well as they do lower fre-
quencies, an effect that can be likened
to natural low-pass filtering of the
sound. The longer the sound travels, the
more often it bounces off walls and the
more intense this filtering effect. For this
reason, the amount of high-end damp-
ing depends on the amount of time that
the signal carries - the signal thrown
back by the room becomes muddier as
time goes by. This effect is stronger with
walls that have soft surfaces (wood, wall-
paper) than it is with walls that have
hard surfaces (glass, tiles). Consequently,
