PLAN B analog blog

Been trying to figure this one out for a while, maybe someone could
clue me in on if this is a problem or just the way this thing
operates. The issue is on the stepped generator half of the module.
When I have the Mean turned 50% the only voltages I am getting are
positive red voltages. The only time I get green negative voltages is
when Deviation is turned almost completely counterclockwise. According
to the graph here http://www.ear-group.net/varidev.jpg I think I
should be getting the full range of the module. 

With the Deviation fully clockwise (or 100%), the Mean has to be at
about 8 o' clock (or, about two ticks clockwise) before I start to get
negative green voltages. 

Any ideas?
