Hi Rob-

You should be able to get close with two voices enabled: One voice panned hard left to 900 cents and 180ms delay, and the other voice panned hard right at 500 cents and 360ms delay. Feedback 0% for both voices, and both intervals set to unison. The mix should be around 75%. Make sure you have "Pitch Tracking" set to Off, as you want to treat all incoming notes with the same amount of shift, and not restrict it to key.

Let me know how that works out!

Best,

Tom
