EFFECTS SECTION
SPECIAL REVERBS
These special reverbs all have a single
Decay Time parameter.
Rain
Similar to a repeating delay, but with
complex spatial and filtering effects
occurring across the stereo panorama.
The effect on percussive sounds might be
likened to a bucket of marbles raining
down on a galvanized steel roof.
Shimmer
Distantly related to the Rain effect,
Shimmer causes input signals to be
progressively diffused in time and space
across the stereo panorama. The spatial
diffusion is accompanied by a flanging
effect. The program is highly responsive
to left or right-panned inputs. A stunning
special effect with percussive sounds,
especially through headphones.
STEREO CHORUS
The function of a chorus device is to
thicken the sound or to make one voice
sound like many. The way the effect is
achieved is by mixing one or more
delayed versions of the signal in with the
original. The delay times used are too
short to be perceived as an echo, but long
enough so that comb filtering does not
occur. In addition, the delay time is
varied to simulate the random differences
which occur when multiple instruments
are playing together. A slight amount of
feedback improves the effect by creating
multiple images of the sound as it recir-
culates again and again. The delay times
are slightly different for each channel and
the LFO phase is inverted on the right
channel to help contribute to the overall
chorus effect. The LFO Rate and Depth
settings are critical to achieving a realis-
tic effect with faster LFO Rates generally
requiring less LFO Amount and vice-
versa.
