Retrig.

Socket " is the ADSR’s retrigger input, which can be
connected, for instance, to the output from an LFO.
That means that while the gate is open, the envelope
re-triggers every time it senses a pulse from the LFO
(see Fig. 2).

§

Output • $ Output

Whenever the ADSR is triggered, these outputs carry
the envelope voltage as defined by the Attack, Decay,
Sustain and Release parameters (see Fig. 3).

%

Inverse Output

The Inverse Output carries exactly the same voltage
envelope as the ordinary outputs but inverted - with
negative instead of positive voltages (see Fig. 3).
