Hi Ken,
Is it possible to have an external clock control the speed of the Utility LFO?

I have two of your Utility LFOs and is it possible to synchronize all 4 of their speeds through modification?
Thanks,
Steve

I guess anything is possible. You would be adding sync as per VCOs, with a
FET across the integrator capacitor of each. It would be hard sync, and
would only work "correctly" if the clock was faster than the LFO speed.

What kind of FET would you suggest for this mod?
Do you mean it would only work if the Clock speed is faster than the overall LFO speed or it's adjusted speed?

Thanks Ken. Much appreciated!

Same as in the VCO 2N4091 or similar

Faster than its current adjusted speed. Sync works by shortening a cycle. It
will still have an effect if the LFO speed is faster than the clock, but the
result would be muliple output cycles per sync pulse, with only the last one
shortened.
You may get some odd results too, with this being a triangle core. Adjusting
it for a sawtooth output may help.
