Hi there,
I just compared that phaser patch against my Castledine SupraVibe (reckoned to be one of the more faithful univibe clones) to see how close they were… and the short answer is: they're absolutely nothing like each other. The vibe is a much stronger effect than the H9 patch, and a lot more interesting to listen to.
(I don't have a horse in this particular race: I'm quite content with my current setup and was doing this purely out of interest).
