Anything above TTL levels will (should) trigger the START on the PSIM-1.
All you're doing is using an external signal instead of pushing the button
which sends 5V to the I/O pin on the BasicATOMPRO.  It "should" see anything
above a couple volts as HIGH.  I just measured (not very scientifically by
the way) by using a joystick controller and increasing the voltage until the
thing triggered.  I then measured the output of the joystick controller.  It
was right at 3V.

Try using either a short pulse wave or a triangle wave to trigger the
Start/Stop inputs.  I just loaded Woody's gc-sah-sr-qua.bas (GREAT program
by the way!) and I can trigger the PSIM-1's START on mine successfully using
the following:

- VC Wave Output (Blacet VCO)
- Pulse Wave Output (Blacet VCO)
- Triangle Wave (Blacet VCO)
- Saw Wave (Blacet VCO)
- Sine Wave (Blacet VCO)
- Out (Ken Stone/CGS Psycho LFO)
- Clock Out (Wiard Noise Ring)
- Both Clock Outs (Blacet Binary Zone - Normal and Short Pulse)
- Normal and Inverted Outputs (Blacet EG1)
- OUT (Blacet Dark Star Chaos)
- OUT (Wiard Joystick Controller - triggers at 3V)
- OUT (Blacet/Wiard Mini-Wave - both 5V and 10V settings using TRI Input)

Well... that's just about everything I have that can produce a signal to
trigger the Start button on the PSIM-1.

As far as using the AUX out to gate or trigger things... I can use it to
gate the following:

- Blacet EG1
- Blacet Dark Star Chaos
- Blacet Final Filtre
- Blacet Binary Zone (Gate Reset)

The AUX jack doesn't put out enough voltage to work my Blacet VCA (since it
doesn't really start to work until it gets to just over 8V), but that's the
only thing I have that I can't get to gate.

I'm running the *exact* same buffer on the AUX output as you guys.  The AUX
output on the PSIM-1 is approximately 5V out.

I hope this helps.
