The gate level of the A-190-3 can be changed to +12V internally. For this
the jumper on JP10A (behind the CV1 socket, labelled "GATE 5V JP10A") has to
be removed and installed to JP10B (behind the 16 pin bus connector, labelled
"GATE 12V JP10B").

The trigger is just a capacitor (nothing but the simple high pass on the
A-100 DIY page). Or you may use an A-162. But that's a bit "overstyled" for
this simple application.
