The idea is to preserve 'continuity' of a smoothed warped ramp when it resets, by ensuring that the derivative of the ramp function is the same at both ends of the ramp

In InputOutputCharacteristic, you could try setting the starting slope and ending slope to the same value.
Thank you! just discovered the slope parameters in InputOutputCharacteristic and it's going to be of great help. Is there a way to calculate the slopes for 1. of smoothing based on the slopes the in and out values set when smoothing is set to 0.5 ? I would like to set the start and end slopes to the same value the end slope would be if the ramp would continue beyond 1. up to 1+ the-first-nod
You could try using

(lastY - secondToLastY) / (lastX - secondToLastX)

for the start and end slopes.
