 How would you patch to get this result (in red below)? It's so simple I'm having a moment: I have a Logic 166. Cheers!

 You want (NOT A) AND B, so first patch A in an inverter (the bottom ones), and then take that output together with B in on of the upper parts and take the AND output.

 B AND NOT A
Joe.
 Fine then

 (NOT A) AND (B) should do the trick. In patch terms I would patch B into a VCA input, invert and offset A, so that it's in the positive voltage range, and put that into the VCA CV-in. On the A-166 I'd patch B into input 1, A into the invert function and then into input 2. The AND-output of the first logic block should be what you want.

 FORUM TO THE RESCUE! I love it when something gets answered quickly and people figure stuff out. No involvement from me of course just sharing some love for the forum

 I remembered I did it in a session, but my brain refused to work this morning LOL thank you, you guys are the best! If anyone interested, here is the sheet I did, inc. basic operations (not visible in the screen shot posted above) https://docs.google.com/spreadsheets/d/1N8U25a3swj4MnJ7PIYm7DaekNePm5f QIcDYOi_VCR_w/edit?usp=sharing
 Invert a square wave LFO. Send the original to A's VCA, and the inversion to B's VCA.

 Ok I had to delay the track B (veerrryyy slightly) and make the gate shorter than track A. Works perfectly now!

 Guys, how do you deal with timing delay in such patches? In this example, I have to invert the track A before Patching into one of the inputs. This way, there is a very very delay between the two track compared and so I have a very small trigger (the length of that trigger is equal to the delay=time for track A to be inverted). How can I get rid of it?
sir stony
 I'd use the A162 before the logic to adjust the timing. I reduced the timing caps on mine as the stock 2ms minimum value is somewhat coarse to fiddle with such miniscule adjustments.
