4 of the CV inputs on C6, C7, C8, and C9 are not mapped to the pins described by the datasheet. Instead, they are mismatched.
I was not able to figure out why the mapping works as expected on Seed but not on Patch SM. To overcome this issue, the temporary solution was to remap the pins:
| Connector |
Expected pin |
Actual pin |
| C6 |
CV5 (PB1) |
CV8 (PC1) |
| C7 |
CV6 (PC4) |
CV7 (PC0) |
| C8 |
CV7 (PC0) |
CV5 (PB1) |
| C9 |
CV8 (PC1) |
CV6 (PC4) |
