Many years ago, when I had a Repeater, David Torn hinted me at the  
trick of running a MIDI sequencer synced to the Repeater and sending  
in MIDI to do "square wave pitch modulation" of loops. First I tried  
CC14 but the Repeater was too slow to react in a musical way. Then I  
tried MIDI notes and that was working like a charm! Simply select one  
of the track select buttons on the Repeaters front panel and send  
MIDI notes into the machine; it will then hook up that track to do  
pitch follow according to the received MIDI notes (just as the  
Augustus Looper AU on Mac does). Bill Walker also used to play with  
this Repeater technique before he was bitten by the Looperlative. I  
pretty much do this old Repeater trick these days on my looping  
laptopo by scripting in Mobius.
