I saw this on the EDN website-thought it might be of interest here.

I 'spose this circuit might not be quite in the spirit of the Lunetta - nonetheless...
Here's a pic and an mp3. The clip is three parts -

1. Simple Sequencer CV into circuit with no filters or gates...Raw osc.
2. Osc only with CV from Fritz Driven Chaos... (I played around with this for quite a while)
3. Sequencer/Osc. /Mankato filter/VCA with AR Envelope Gen.

Hi Dan,

I kind of thought you would like that part Wink For my part, I'm just fascinated with this little VCO...

It's the (EZ Chaos? (driven double well)) with the "dwell hack" Ian posted once...Although I can't find the post now....here's the 'hack'.
I'm driving the chaos with an lfo.

We're well out of Lunetta-land now. Wink

EDIT - Non-Linear output from the chaos
