A voltage controlled envelope will allow you to variably shape the curve by
feedback. Feeding back a positive envelope will bend the curve down like an
exponential decay slope. Feeding back a negative envelope signal will bend
the curve up like an exponential attack curve.

The amount of feedback controls the amount of bending.

This is covered in the Serge users manual under DSGs.
