Cut and trace for control voltage insertion.
Roland MC-202 - CV/Gate Modification * I wanted to use the two unused jack locations on the rear to carry the new CV and Gate jacks - but internally there are some parts on the PCB right behind the rear panel…

Roland MC-202 - CV/Gate Modification * …so I replaced them all to the solder side of the PCB; there's enough space between the PCB and the bottom of the case.

Roland MC-202 - CV/Gate Modification * Now there's free space for the two new jacks.

Roland MC-202 - CV/Gate Modification * They'll fit!
