There was once a home organ that featured a variation on the ribbon
controller theme. It had a long row of several tiny rollers, placed
side-by-side. It was interesting. I might be able to find out more details
for you. I'll let you know if I do.


If you would be happy with a short ribbon controller, you could probably
modify a long slide pot. Take the shell apart and just use the internal
resistive strip. Add a thin plastic spacer over that, which has a long slot
in the middle. Top it off with a flexible conductive membrane of some sort.
You would use the two "outer" terminals from the resistive strip, and
attach a third wire to the conductive membrane, to serve as the "wiper."
As far as durability is concerned, you should be able to make something
more dependable than a factory slide pot, since this device could be sealed
from dust.

Does this quick description make sense?
