Doepfer

Hello Asbjörn, check the: Power Source interference thread as it 
adresses the very same prob. The only difference I see from this 
distance btn stuadh's and your issue is that he employs recommended 
PSUs by Power One (HAA or HBB series I suppose) so you could try a 
better PSU (ie the new one by Doepfer)if you don't want to go for 2 
diff. distrib. boards (see above ment. thread). When I started out 
with a 2nd hand system G6 frame I had the same issue. It has 
disappeared since I use a different PSU. (Or my patches have just 
got noisier?) Regards, Ingo aka...
