I also soldered the MG2 clock on the 356 board instead. Specifically to the right side of the 10k resistor from the arpeggiator trigger mod at J42. Now the sample and hold is clocked by MG2 or by the external arpeggiator trigger in depending on what is hooked up.

It is not the MG2. It is the Arpeggiator: the arpeggiator clock-in is a
"switched trigger" and - if fed with a voltage clock - clocks on the
negative edge.

You find a instruction for the modification on
http://fa.utfs.org/diy/korg_monopoly/modifications.html
look for: "V-Trigger to S-Trigger Adapter for the Arpeggio Clock"
