Potentiometers in this project were different than the ones from the first version. The first version had insurmountable problems with analog values. In this version, the issues were not uniform, so it was obvious to find the faulty potentiometers, and since they were designed as stereo equipment, it was possible to use the secondary side instead of replacing the entire device. An example is shown below where the other three pins were used.

All of the discrete inputs were mapped to a sketch of the face. Each switch was tested with a diagnostic program to make sure it was going where it was supposed to, but there were a few cases where pairs of wires became swapped. It will be easier to fix this in the software than to remove the wires and solder them back in place.
