SWEET!!!.. I think I figured it out here....

Distortion needs to be set to NG (noise gate) or 1 or above, anything
but 0.

and of course your osc 1 and/or 3 needs to be at a level of at least
around 3 because they are what control the distortion noise gate (page
58 of the definitive guide to Evolver)

Try that out and let us know your outcome.
