Will check Wednesday nite, but sounds like a very good shot bud, thanks!  I 
just added a serial cable extension which now runs together with the audio 
line away from the Korg.  I had problem before this though, maybe not as 
severe, so maybe positioning of cable might help me out, I'll let you know 
here.  I just hope it's that, or a ground solution and not serial data 
entering the host port contaminating audio within the Korg itself!
