Doepfer

The simplest solution is to add a resistor in the range ~ 47k....100k
between the input of the A-165 and +12V. If you are not able to add this
resistor I'm sure our representative in your country can do this job.

And this is how it works: S-Trig is open in the non-active state (like an
open switch), and closed in the active state (like a closed switch). As long
as the S-Trig is not active (i.e. open) the additional resistor causes the
A-165 input to read "high" and consequently the A-165 output remains low. As
soon as the S-Trig becomes active (i.e. closed) the A-165 reads low and the
output turns high.
