Lost in quantize planet

Hi, guys.
I’m having some problems when I try to modify a loop on BeatBuilder if the original loop is a little complex, specially if swung. Sometimes I can fix it by firstly quantizing the loop on the BB Midi Editor, but some of them go crazy: start in the second beat, divide the bar in a lot of parts, mess the triplets and so on.

Have you found some simple way for making the loops more friendly to the BeatBuilder? By the way, how do you write down triplets on the BeatBuider?

Thanks in advance.
