All about the Roland Jupiter-series

I don't know if we I'm talking about the same, but on my jp8's 
outputs (as well as on other jp8's)there's some low-level digital 
noise on the outputs (just like the sound of a computer modem). The 
sound changes when you press patch buttons to select another patch. 
I've heard some other people complaining about this, so I guess it's 
in the design...
