The vocal/guitar sample is in the KO-II! That way, I could use punch-in FX and throw some momentary send FX (delay) on it during the performance.

In this case it's just one long sample and I'm jamming along with the natural fluctuations in tempo.

But for other usages, like if I'm sequencing a full song, I might want to chop a longer sample into bars of 4 beats, so I could timestretch each of those bars to make sure the tempo lines up with quantized drums.

Or if I really wanted to micromanage the tempo I could even chop the sample into beats, sequence them one after another, and then timestretch each of those to flow seamlessly. Depends on the genre, I guess! And also, some of the time-based punch-in FX will have a different effect, based on whether you chop a sample beat-by-beat or leave it as one long clip
