here's from the sept. 89 issue of electronic musician, p70:


                                                    S-trig out
                                          ----------| |--------
      Gate        10k                    /                    |
	[v-------/\/\/\---------+-------| 2N3904             ---
        |                       |        v                   ///
        |                       -        |
        |              1N4148   A        |
        |                       |        |
       ---                     ---      --- 
       ///                     ///      ///


and here's another one from the paia kit, pretty much similar to the above:


                                                    S-trig out
                                              RadioShack #274-201
                                            1-gnd, 2-voltage (5~15v;0v active)
                                          ----------| |--------
      Gate (0v;5v active)                /                    |
	[v------------------------------| 2N3391             ---
        |                                v                   ///
        |                                |
        |                                |
        |                                |
       ---                              --- 
       ///                              ///

Right, you can do it with an NPN transistor and a 10K resistor... (or
47K or whatever you have at hand...)

one end of resistor to gate signal, other end to base of transistor.
Emitter of transistor to ground of incoming gate signal, and ground of
Mini' S-trig input. Collector of transistor to S-trig signal input. Don't have
the pinouts for the S-trigger connector available, so I can't say which
pin is which at the moment.

I could of course make an ASCII diagram, but what the heck, it's such a
simple circuit...
