Yes, that was the idea. Build a good (and you guys are far ahead
of me there) tracking expo VCO to start with, and then make the
inaccuracies common to linear VCOs switchable with my little
capacitive divider / minimal offset current circuit. Think of it as a
"Korg Trident" or "Yamaha CS" tuning courve (;->)
(Only joking on the last one - I have never measured the actual
courves of these.)

Must be great ! One might convert this into a breakpoint / slope
tuning courve on a VL7, too ...
