The Tannerin is not really a ribbon device.  The slider that goes across
the top is mechanically linked to a potentiometer that is used to control
the frequency (or supply control voltage in the case of the one I am
getting.  I think the tricks of construction are a rugged, yet easy to
slide mechanism and a method to connect that motion to the pot so that the
result is a rather linear scale (although it will not be perfect). 
However, since you "draw" the keyboard template onto the top under the
slider, some slight non-linearity can be compensated with by stretching one
end of the template.

I am hoping that Tom will get to mine soon.  I have been standing in line
for a while, and these are one-offs.  Mine will be different that the
others he has made since control voltage is my only required output.  The
other ones he has built are self contained and include the oscillator
circuit too.
