Signal Flow
The signal flow in relectro is pretty simple
The audio being sent to relectro first got split into two parts, like in almost
every effects unit, one part remains as the Dry signal which can be mixed
with the Wet signal in the output section, I'm sure you heard something like
this before.
The part of the signal which is going to become Wet part is the sent into
relectro's Input Filter. This filter actually works like a splitter, as you can see
in the above diagram, a part is sent to the Leak control and the other part
gets into the Input Delay.
From now on its pretty linear, the Input Delay (more on why there is a delay
in the input section later on) sends the signal further to the main
processing , from where it gets to the Output Filter, the Output Chorus to
the Wet control for being mixed with the original signal.
As you see the modulation section is not involved in the audio signal flow,
however, as you might have guessed, all the modulation origins here and
the control signals flow from the modulation section into all the different
parts of relectro.
