CV
Control voltages for the decay time are patched in
here.
H
The actual decay time t
D
is determined by a
combination of the level of the CVs themselves,
and the positions of decay control 1 and the CV
attenuator 2.

Inv. Gate Out
The sockets for the gate output $ and inverted gate
output % respectively.
5. User Examples
Since the A-142 is really a simple envelope, with just
the one parameter to control, ideas for its use can
include any of the occasions on which you might use
the decay characteristics of an A-140 ADSR or A-141
VC-ADSR.

The patch in fig. 2 produces a random decay effect, so
that each key played has a percussive envelope of
