Thank you for checking for me. That's interesting. I'd also appreciate anybody else's experience with their Pro 2.
During Dave Smith's eurorack module demonstration, the hack effect seems a lot more gradual to my ears. Maybe that's due to the program material (drums), but my unit does not sound like that. It's so abrupt when I get to "7" that it almost feels like an ON/OFF. If the onset of the effect was a lot smoother throughout the taper, as demonstrated in Dave's video, I'd certainly get much more mileage out of it.
