Nice!! It looks like you're getting a lot of mileage from those 3916s.
One thought about the offset added by the Slope control - would it be
possible to use a dual pot, and have the second element add a DC
voltage to the output summing amp? This voltage would be opposite
polarity from the offset, and could cancel it out (or at least help
minimize the effect).

Anyway, don't keep us waiting and post some audio samples as soon as you can!
