Korg Poly800/EX800 Users

Hello Neil,
you have any information on the implementation of the change with external knob for data entry?
I also wanted to make it on my Korg Poly 800 ..
can you send me some advice or process to follow?
thank you

     Hey,

Is there any better sources for the data entry knob mod on here or elsewhere?  I'm too much of an amateur to understand the schematic.
