Some early models of QS8 had trouble on an X-stand, resulting in loss of velocity response, particularly of the keys around middle-C (it's described somewhere in this forum).
Apparently Alesis has reinforced the frame. But the manual of my (recently bought) QS8 still recommends placing it on a flat surface.
