Don said:The potentiometer is not of normal construction. The
resistive "track" is low impedance from one end to the half way point (this
feature is not utilised in this controller) other than to provide a
"tougher" end zone for the wiper contact.
Sounds like a normal (i.e. crappy) approximation to a logarithmic pot,
such as is used in audio gear. They have exactly this feature.
It's most unlikely that Janome got custom pots made, so you should
just try a normal log pot.
