Help with Stutter Edit and Midi Tracks

Has anyone had luck trying to use Izotope’s Stutter Edit on midi tracks vs audio tracks in Cubase?
I’m using 6.5.5.

Any assistance would be greatly appreciated.

FYI, I’ve been trying to mangle FXpansion’s Geist that I have on a midi instrument and then sub’d to individual track outputs in the mixer. I know I can render to audio and then use Stutter Edit but I’d like to be able to do it this way.
