In the PCB version I used 1uF caps throughout because that's all I have in 0805 SMD size, so their values are not critical here.

Each oscillator is modulating the others pulse width, and there are two possibilities for disrupting the circuit with crystal diode clipping, the input signal is fed into the circuit and there is a breakout jumper so multiple of these modules can be chained for more complex feedback. I haven't tried much of this yet.

It slightly bends the variscan synthesis rules in that it works in an interesting way without a crystal in the circuit. This makes it more forgiving in a live setup, but I think it does exhibit differences between different semiconducting minerals when they are used.

===Inputs===

* Choice of two locations for a crystal diode: X1 limits the buffering like a soft clipper (needs connecting to work when not in use) and X2 hard clips the input to the first oscillator.
* CV input
* Audio input feeds into the circuit.
* Breakout location to chain multiple chaotic relaxation oscillators together.

===Controls===

* OSC 1 pitch
* OSC 2 pitch

===Outputs===

* Audio signal
