Guess what... I wanted to use a 10 turn for fine and a 12 position rotary
switch for coarse. Two pots a la formant may be a bit hard to adjust.
Better would be 12 turn , of course, then it would be possible to read
halftones directly...  If one rotary position is one octave, I could
get 1/100 octave, isn't that 12 cent? Should be good enough, considering
all the other drift and errors.

12 positions seems to be the maximum available, does anybody know a
source for rotary switches with more (please not those very expensive
rotary switch kits).
