Very pretty flowers! Any chance of a zoomed in photo to show your balcony from the outside? (Cropping out your neighbours of course)

Yes, it was the VCAs, which were exponential. They are now linear, and it turns out the spectral transfer stuff was working just fine.

I think I'm going to have to pull my build of this from my rack, and tack on some flying test wires.

I'm using the subcircuit in another module, and would like some kind of visual indicator Very Happy

Do you get Australian magpies over there? They aren't corvids, but they are very smart.

Interesting. How dependant is this circuit on specific transistors? (I've built the 258 VCO before, and it is really, really dependant on selection of the sine waveshaping FET.)

I've got a few wallwart style PSUs, and the only problems I've had is when I've forgotten to add heatsinks.

If the soldering is cosmetically a bit dodgy, that might be my first suspicion.
