I've searched and haven't come up with an answer yet — with the Quadravox, I know that each harmony can come out on its own delay. But it seems to me that there's no way to get them evenly spaced. No matter how I set it, at least one of the harmonized notes is at a different delay rate than the others. Does this make sense?
Anyway, what I want is for each one to be evenly spaced. As an example, original note then a 300ms delay before the first harmony, from there a 300ms delay to the 2nd harmony, and so forth to the 4th harmony.
