On the first ed schem, A118, A119, 120, 121, 122, 123, 114, 112, 113 are all involved
"AT" means autotune...

Not sure what chips on the later schem, as I don't have that one.

Check the clk pin on A118 first as that is the input to this circuit from the oscillator
that is being tuned. You will have to dnld the 4021 data sheet to get the pin number,
as the nice folks at Oberheim were too lazy to put it on the schematic.

Thanks for the responses everyone @65 lotus... It sounds
fine when turned on. Played it for quite a while. Nothing
terribly out of whack.... until you hit
autotune.  
@Bob thanks again. I will do that. At the risk of
sounding lazy do you have a component and pin where I could
find that or at least know which schematic to look
at
