MOTM

inspired by david bivins' post about sending trigger signal from a 606
to the 120, i figured "yeah!  now i can sync the the 410 LFO rate to the
606!"  alas, it doesn't seem to work.  can someone tell me why?  does it
have something to do with my not installing that mysterious optional
resistor?  and while i'm on the subject, what does that resistor do
anyway?

sorry if any of this has been brought up before.
