Organelle ground noise: how much is normal?

Organelle

I recently acquired a used Organelle from the Ebay. I love the Organelle, exactly what I wanted. My question to all the Organelle users is: do you feel the Organelle has more ground noise than average (compared to your other devices / instruments)? I’m just trying to get an idea of what a normal amount of ground noise / white noise is for the device (and to rule out that something is not up with my unit).

When compared to my Septavox the Organelle has a lot more ground noise / white noise and this noise also sounds different.

-Thx-

The audio input jack sometimes produces noise in sampler or effects patches when nothing is plugged into it, but other than that if I’m using a patch where there’s no audio in - there’s no noise.
