I have a PreSonus Faderport that works fine with one exception. When I mix using touch input touch input with the fader, If I remain still for more than a second (still making contact with the fader), the Faderport stops receiving input from the fader until I move again, yielding intermittent data during that still time, and mixing the old mix data in with the new mix data. Maybe a driver problem? I did update my firmware, but to no avail. Also, It seems to me, the ballistics of the fader are very "jerky" (I can't actually tell about that yet, due to the jerky nature of losing that input every few seconds). I would deeply appreciate anyone's thoughts. PreSonus is no help since they only support the product by email, and that's not good.
