Trigger, gate, and CV routing updates led holes to PCB edge 9.12mm, see https://disti-assets.s3.amazonaws.com/tonar/files/datasheets/16730.pdf 62-pin D-Sub connector, horizontal/angled (90 deg), THT-mount, female, pitch 2.77x2.84mm, pin-PCB-offset 14.56mm, distance of mounting holes to PCB edge 9.12mm, see https://disti-assets.s3.amazonaws.com/tonar/files/datasheets/16730.pdf 9-pin D-Sub connector edge mount solder cup female x-pin-pitch 2.77mm mounting holes to 5mm + unplated, and revises jack footprint updates led holes to PCB for holding three chips (two 74s, one 72) Noise MK's S&H not strictly a noise generator, but contains one? See above MK's three-color noise generator to a dual or quad would add very little cost even without 1v/oct, could be other values, ceramic may work, test debouncing. Maybe enlarge footprint if needed.
