These are my build notes for the Nonlinear Circuits "This 2 shall pass" module
It's a eurorack format 2HP module.
Should be a simple build ... It's a passive analogue XOR circuit
No CMOS ... which is different & nice to see.
How to build a logic gate with transistors is a basic circuit which is a handy piece of knowledge.
There are 2 ways to use this:
1. If you want to get close to XOR behaviour, use the top and bottom inputs, leave the middle one empty.
2. if you want a voltage controlled “XOR” feed your signals to the top and bottom
inputs and a CV signal to the middle input.
Feed it anything: CV, audio rate, gates, mix them up. Generally with audio signals it sounds like a Ring Modulator, adding CV to the middle input (but feel free to experiment) it sounds like a VC Ring Modulator.

XOR Gate (Exclusive OR gate)
Will only output a high signal when one input is high and the other is low.
It allows the signals to pass Except when they happen simultaneously.
It's like when 2 people try to squeeze through a narrow door at the same time.

(use this for your two snare drums - to prevent them triggering simultaneously)
