Hello gang,
Back from my vacation. My wife and I had a nice trip. Lots of snorkeling and warm sun in the Caribbean. Also lots of Tequila shots and Margaritas.

I did this demo on my laptop on the cruise ship, just for fun. It's the famous Ring Modulator in the diode configuration.

Later then, BobF......

Fascinating!

The outputs look similar in frequencies but the wave shapes differ. I’ve put the diode version into my toolbox for further experimentation.

I’m busy with my own project at the moment but it would be interesting to hear what audio effect would be achieved if you emulated silicon or germanium diodes, rather than using “perfect” ones.

My guess is that the output would then change harmonic content as the input amplitude varied, and this might have its uses. You’d need to increase the incoming amplitude to get past the “forward voltage”.
I never experimented with the real thing in the past, so I don’t know what I should expect sonically.

I’m also amused that you spent part of your holiday on Flowstone

Cheers
