I don't like to bug Bob. :)
When he hires me for something, we stay in contact, but he's a busy 
guy and I should know this stuff.
The synth has been out 30 years ;-)

Btw, the whole thing about this Sonic Six weirdness is that since 
there's only one transistor per vco and no init freq trims. The temp 
setting affects both the base freq and low end scaling heavily.
So it's like playing baseball on a rotating field. ;-)

Btw, vactrols came to rescue here in a most non EM type way.
I have a remote camera on this property. Good for security, but also 
because in a geodesic dome, there's blind spots with no windows and 
we can't see if UPS is here, etc.
The driveway is over 150' long.

It's a consumer Sony handicam on a rotatable, tiltable base about 60' 
feet away from the house.
But the stock zoom control was via a membrane "slide pot."
A resistive coating applied to a thin, flexible sheet that's 
impossible to solder to.
But I was able to open the camera and added some wires that then went 
to two vactrols.
The vactrols are controlled remotely, but offer isolation between the 
house and camera that I felt was needed. I didn't want some sort of 
damage to the camera via too much current or having their circuitry 
actually hooked to long runs of buried wires. So, the vactrols work 
excellently as a go between in this application and not only can I 
zoom in and out like before, I can remotely control the *speed* of 
the zooming as well. :)

This was why I mentioned vactrols as a go between for controlling env pots. :)
