Hi Jeffrey
My reasoning for connecting the unused pins to GND. Was that regardless of whether they were used or not they were connected to the PCB headers and that grounding them may help reduce RFI. At least it wouldn't hurt.
Hi Jac
The 2 line interpolater uses 2 lines, the 3 line uses 3 lines and the 6 line uses 6 lines.
The 6 lines are always 'in circuit' but when doing 2 or 3 lines the unused lines are given '0' coefficients so they will have no effect.
