I think by midi loop in your original post, you were referring to a 
pattern that loops continuously within the E-mu itself, right? If so, 
a loop could be created in a set of one or more sequencer tracks or 
with an arpeggiated sequence of notes (the arpeggiator).

If you want to record CC [continuous controller] data into your 
sequenced tracks using the knobs, you are limited by the amount og 
your remaining memory.  If you "push the limits" of either memory or 
performance with an overabundance of CC data from going crazy with the 
knobs, you can thin the CC data using the THIN EVENT menu in the 
pattern editing menu system.

I hope this come close to what you were trying to ask. If not, feel 
free to clarify.
