I authored that and probably should delete it.
I abandoned the project when I couldn't get a good response from the P800.
I believe the problem is that the MPU is not scanning fast enough, coupled with the problem of a wide enough pulsed signal from the encoder to keep the 4066 switch closed long enough.
That's my best guess. And is probably why we have not seen a successful mod like this work.
It's a mod that seems to require modification to the firmware to actually support a encoder for value changes to parameters to work decently.
