The client is thinking 9mm or 10mm distance between track names in
the playlist (= 171mm or 190mm travel overall by the pointer) and a
pot is around 60mm so a 3:1 reduction gear would do the conversion.
He had a printout the other day on an A4 but I don't have a copy so
can't confirm the distance he picked

A good little thought exercise
