Not exactly sure what you mean by a looper.  It depends upon whether 
your CV is continuously variable or steps between discrete values.

I did an arpeggiator where I would monitor the CV for a change since 
it was hard to detect a trigger (I since use edge interrupts).  With a 
real-time clock, you just timestamp the CV value change. Ram use is 
minimal since you just have a record of the changes.  Worked great.

I did something similar for a CV delay which can implement some really 
long delays.  Sample the CV transitions and clock them out at a 
variable delay later.
