[sdiy] 30V switch with 4016 pinout?

[JH.]

Don't worry about it - it works ok as it is.

Would "current mode" operation of the 4016 be doable?

Looking at this Polymoog Resonator section schematic (from Peter 
Ulrich's post)

http://www.minimoog.net/polymoogresonator.jpg

It looks like the 4016 could easily be operated as a current mode switch 
with the ganged outputs going directly to the summing node of an op amp. 
In that case, voltage level stays fixed at wherever "virtual ground" is 
for the summing node.
