Years ago I had also similar problem with some instruments, forgot which it was… Later i have found it had something to do with ground loops, or lack of grounding, something like that. If I remember well, it was solved by changing some cables, or changing mixer, or so. After moving to Japan where power sockets have no earthing pin, I had to make a grounding rod for all my 220 Volt gear (I use few huge transformers to convert Japanese 100 Volts to European 220 Volts, because I couldn’t change voltage in many instruments) and all problems of this kind disappeared.

I rarely use my CZ, so I don't know if I still have it. However, I seem to remember it might have been tied in with my PC/sound card. > > Do you have your CZ connected to a computer? If so, do you get the noise when the PC is not on and the CV is not connected to it? Also, if the CZ is connected to other gear, do you get the sound when the other gear is off and not connected? > > Steve >
