Recording CV/Gate inputs is inaccurate

[funqpatrol]

Are you sure that
A: your outputs of the Rene are calibrated well. So Note C-1 is exactly 1 volt and C-6 exactly 6 volt for example
B: Did you manually calibrated the inputs so they match with the Rene?
C: Are the CV outputs of the Rene generating any slew for the CV voltages so the voltage is not stable when the gate comes?

Thanks for the insight, will make sure all these points care checked
