The plug workaround did work to a degree. The exp. pedal worked via MIDI, but, the pitchbend had a tendency to "jump" at the end of it's travel. I've just decided to run an extra cable from my VP Jr. to the PF until Eventide gets this worked out. I did hear from Eventide and they said that their engineers did confirm that it was a software bug peculiar to the Pitchflex setting. They also said that they are working on it and hope to have it corrected in the next software update. In spite of the problem, I have to say that Eventide has some darned good customer service, at least in my experience.
