Hi all,

  I've noticed recently that I'm experiencing some interference 
from a number of modules in my system.  It is noticeable only 
when the VCA is open it most noticeably comes from the A-146 
(the RS40 clock, and RS80 LFO have a lesser effect). 

  It sounds a bit like having the LFO plugged into the filter cutoff 
but it happens even if the filter is not in the patch.  In fact, I've 
tested it with a patch running the VCO directly to the VCA with the 
gain up and nothing else patched in.  I've even moved the LFO 
around with but the interference doesn't go away.  It is definately 
the above mentioned modules, as changing the frequencies on 
the module changes the sound of the interference.  Is this 
normal?   Can I shield against it?
