The A-141-2 has an exponential shape as most ADSR. But it's possible to change the slope form. The info page of the A-141-2 says:
"The control voltage inputs for A, D and R can be used also to change the shape of each segment. To change the shape of the Attack
curve the inverted envelope output (Inv. Out) has to be patched to the CVA input. Then the CVA control is used to modify the shape
of the Attack segment (CCW = usual exponential shape, about center position = linear shape, CW = inverse exponential shape). Same is
valid for the shapes of Decay and Release also. But for this the non-inverted output (Fixed Out) has to be patched to the CV input
in question (CVD or CVR or both)."
