I was attempting to do an auto tune using just Chromatic tuning, since I didn't know the key signature. I tried jacking up the attack, and sensitivity just for the kicks, and the result after processing was hearing a LOT of clicks that sounded just like the clicks that happen when you're buffers are too low; which they aren't since they sound fine on other files. So, it's not a real big deal, but I haven't heard that in my other tuning apps. Just curious.
