After be processed on the Preamp section, the signal reaches to
the Envelope Follower. The purpose of this section is use the
dynamic content of our audio signal to generate an envelope
that we can use to modulate other parameters of our setup.
With the response controls, you can adjust the reaction time of
the envelope to the amplitude changes of the audio signal.
With fast settings, the envelope reacts faster to the transients
generating a signal more similar to the original, being the same
with the faders on their minimum position.
At low rates, the envelope reacts slower to the transients
creating a contour that only covers the longer dynamics changes
of the signal. This is particullary useful if you want to use
sustained parts of your audio signal in your envelope.
The Env Level pot sets the amplitude of the resultant envelope
signal from 0 to 1 0V if you use the Positive Output and 0 to
-1 0V if you use the Inverted Output.
Note: the resultant envelope is not affected by the Gain pot of
the Preamp Section.

The last section on Instrument Interface is
the Trigger/Gate Extractor. This circuit fires a
Trigger and a Gate signal each time the
envelope reaches an Amplitude Thresold
selected with the pot.
This section works taking as reference the
envelope generated by the Envelope Follower,
before it passes through Env Level control.
Both signals has 1 0V amplitude but only Gate
signal is sustained while the envelope doesn't
go down the thresold level.
