The signals from 8 pots are multiplexed onto a single line - that's what
each of the 4051s do.
They have 8 inputs, with a pot connected to each, and a single output.
The input that is connected to the output is selected by a 3 bit address.
Each multiplexer output then runs down the ribbon cable to the main board,
where another multiplexer selects from up to 6 pot multiplexers, or the data
and tempo pots, and feeds that to the ADC.

Since the other pots on the same multiplexer are working, and the
multiplexer is working, the problem has to lie in the pot, or the connection
from the pot to the multiplexer.
Make sense ?

Cheers,
