THE ECHOBOY CONTROL PANEL - THE STYLE EDITOR
Echoboy — Version 5
Diffusion is a common parameter found in reverbs that imparts a kind of
“smear” and adds density to the reverb signal. It is what makes reverb
sound dense and thick. The Diffusion parameter in EchoBoy is similar.
Each time the echo goes through the diffusion filter it becomes less
distinct: a blurry or smeared sound. Higher control settings result in
increased diffusion of sound. With short echo times, this can give you
a kind of room reverb effect where the individual repeats meld into a
cluster of short diffused and smeared delays.
At longer Echo Time settings, (and with feedback turned up) the dif-
fused delays can create a kind of plate or hall reverb effect. When in
Dual, Ping Pong, or Rhythm Mode the effect will sound more dense as
you have more than one delay being diffused and each delay can be set
to a different time.
While the Diffusion Amount control will soften echoes, it can at the
same time, cause increased resonance. This is similar to the sound you
get when you turn up the feedback on a Flanger; it will sound metallic
and robot-like. Moderation will be needed to strike a balance between
trying to impart a realistic reverb sound but keeping it from becoming
too resonant and artificial sounding.
The resulting sound is also highly dependent on the setting of the
DIFFUSION
diffusion Size control, the Loop/Post Switch setting, the Echo Time set-
ting, and the amount of echo Feedback – they are all highly interactive.
The Size control adjusts the character of the diffusion effect. Smaller
settings will produce more subtle diffusion effects, and even phasing at
extremely small settings. Larger settings can produce more reverb-like
effects. The best setting for the Size control will vary depending on
your source material. You may find settings that sound really great with
percussive input are just no good with sustained musical sounds, for
example.
SIZE
The Loop/Post Switch defines where in the echo path the Diffusion
filters are placed. In the down or “Post” position the echoes are dif-
fused at the the end of the signal chain, and each echo repeat is equally
diffused. In the up or “Loop” position, the diffusion is moved into the
feedback loop of the echo, and each successive repeat will become
increasingly diffused.
