[sdiy] EFM LFO5 Sync Help

[RFAHL]

Hello,

Thanks for the perfoboard recommendations.  Looks like a quick trip to Rat
Shack is a good place to start.

I have been working on an LFO that Tom G. of EFM designed.  I've been
modifying it a bit and need some assistance with that.

I added a 3pole rotary switch so that I could add a range of caps to extend
the LFO's range.  This works.

I tried adding a sync input, like on the Korg MonoPoly LFO:

This does not work.  If I connect this to the LFO, it no longer oscillates.
Inputting anything into the sync input has no effect.  It seems like the two
LFOs are similar enough that the Korg sync input should work with Tom's LFO.

I've uploaded Tom's schematic with my mods added to it:

If anyone would care to take a look at it and tell me how I might get the
sync feature to work, I would greatly appreciate it!
