I recently purchased a FaderPort 16 and noticed that when I would power it on, about half of the time the faders would operate in a stuttering or jerking fashion. Other times when I power it on, the faders move smoothly. I opened a support ticket with Presonus but they could not confirm what the issue is. The issue occurs only with the latest firmware (3.44). I returned the unit because I did not want to get stuck with potentially defective hardware.
I'm thinking of re-ordering another one but would appreciate if anyone can test theirs and let me know if you notice this. I have a feeling it's a firmware issue but can't be certain.
Here is a video where I demonstrate the problem. Note that my computer is not connected so it has nothing to do with the issue.
Thanks in advance for any help.
