Wanted to give this one just one more shot. Did get one suggestion 
(thanks Jon) which wasn't quite what I was looking for (but useful in other 
contexts nevertheless).
Sort of expected perhaps one or a few other Repeater users to chime in and 
acknowledge that this functionality (tell Rptr to let the loop play to its end, 
then stop) is at least desirable, albeit not possible with the current 
OS.
I imagined it would be only a matter of time before someone would announce 
they had hacked OS1.1, and made all sorts of improvements... such as being able 
to configure one track as a MIDI looper...

  Subject: Repeater - "conditional 
  stop"
  
  (Sorry if this has been discussed before, couldn't think of a good search 
  argument to hit the archives with.)
   
  One thing I like (and use) a lot about the DL4 is the "Play Once" button 
  (third from left), particularly in song settings. I'd have the DL4 run a few 
  repetitions of a section, and right after the start of the last desired 
  repetition, I tap Play Once to tell it to play exactly to the end of the loop, 
  then stop. Very seamless and elegant.
   
  As a guitarist, I love this as it allows me to prep the looper in 
  advance, since at the very transition I'm anticipating, I usually have lots of 
  other pedals to hit, often with a time-critical requirement.
   
  Alas, no such thing with the Repeater (at least, not as accessible and 
  intuitive) - which I would prefer on occasion because unlike the DL4 it loops 
  stereo/multichannel.
   
  The only way Repeater is able to respond in this fashion, to my 
  understanding, is by "queueing an empty loop".
   
  There are several drawbacks to this - not possible via simple footpedal, 
  would need to use hands to press buttons & turn knobs, or would require a 
  midi pedal programmed with the macro "queue next loop, wait for CFC, hit play" 
  or some such. Not to mention that the next empty loop might be several loops 
  in the list removed from the current.
   
  I've checked Repeater's command set to see if a MIDI pedal implementation 
  might help me. I can't think of a good sequence that would result in the loop 
  stopping at the end, and with the original loop loaded in memory.
   
  Are there perhaps more sophisticated Repeater operators on the list who 
  have scratched their head over this same simple problem with positive outcome? 
  Would love to learn. Much appreciated in advance!
   
  Best,
  Nic
