Peter Grenader devised a method to avoid using the 4016's at all by
installing a (IIRC) 3PDT center off switch, which makes things a bit easier.
However, I am using Mark's adaptation of the Low Pass Gate using the 4016
mainly because 4016's are a helluva lot cheaper than those 3PDT switches
(but that's just me).


Yes, that would be me.

I lost the analog switch and just went with a triple pole basically because
I was lazy.  That being said though, remember - the only reason Don used an
analog switch on the rev C was for the other sections of that component that
Mark didn't need to incorporate that allowed rev C to be computer
controlled.  If you notice the rev 2 doesn't use them and in fact only
requires a double pole, which saves you a few $$.
