mpc software really hard aliasing noise when pitching down s

tried detuning a sample minus 18 semitones in the mpc software, what im hearing is a lot of aliasing going on, tried the same in maschine 2 and ableton live and i got much better results.
If i disable the Hi Quality algorithm in Ableton i got the same aliased mess as the mpc software, so i guess mpc pitching algorithm is not so "HI Quality".
I mean this is not a huge issue, normally i would not picth a sample more than 4/5 semitones, just noticed this because started experimenting with som slow tempo beats.

and IMHO it is not pleasant to my hear like the aliasing you would expect from an sp 1200...
