Actually, I could hard pan my mixer and send only the left channel to the 
  DD-20. That kills the stereo advantage, but makes short work out of the 
  problem. I just pan left the instruments that I want looped. 
   
  However, after an evening playing with it, I'm wondering if I didn't make 
  a mistake just getting started with this. It's not like I thought it would be 
  at all. 
   
  Because I want to capture parts in mid performance, it's very difficult 
  to do. I did play games where I play a bass line, add a rhythm (even added 
  percussion) and then jammed over that, but that is really NOT what I bought 
  this for. I accompany myself fine in real time so making loops like that 
  leaves my left hand doing little or nothing. 
   
  I don't know, maybe I'll play around with it some more before I decide 
  this isn't for me. 
   
  I can't even adequately explain what it is I'm trying to do with it. I 
  think the closest I can come to a description is that I want a "super 
  arpeggiator" that I program in real time in performance. Like, I'm 
  jamming on a groove and then capture a run on my lead synth which keeps 
  repeating while I play a counterpoint to that run. Then I seamlessly replace 
  the first looped run with another, etc. etc. etc. 
   
  Is that clear or am I doing a bad job of expressing this?

    Well... there IS a limit to how much a small mixer can manage. My last 
    sentence addresses fading the aux levels of instruments you don't want to 
    record.
     
    There's no way around having to manage auxes to the looper input if you 
    absolutely must have access to every instrument. The other approach is 
    to dedicate each looper/s to one or two specific instruments and get happy 
    with those limitations.
