Don't stick the output of the LFO into a '820 CV input would work.
But, you just need DC offset to avoid negative voltages. I think the
SAW out, with SHAPE around mid-range, will work. Check it on a 'scope.
This will make a 0-5V triangle.

Nope.

If the GATE does go to near ground (say, below 0.050V) then it should
BYPASS. I will test this out today and add a blurb to the manual. THe
pullup resistor is 2K7 to to +15V. So, you need to NOT hook it up to say TTL
outputs :) Moog S-Trig with pullup to +15V (an option of Kenton Pro-2000)
should work, as well as true open-collector outputs.

Err... that would be ME, circa 1978.
