Those are loops of live playing, just as now they are loops of MIDI. The repetitiveness will not change, just the means of producing it...

Whether the loop is four bars, or eight, or even sixteen (thank you, Korg!), the fill remains the same every time you use it. A dead giveaway, IMO (and no thank you to Korg for only the two and a break/Fill system!).

People will often notice the repetition in a fill more than the repetition in a loop...
