basically, you can rely on the diagram shown in traktors (or the audio 10's) setup guide - it pretty much works similar.
connect the A, B, C, D line outs of the audio 10 with the line in's on the vms.
on the back, switch all channels to LINE.
on the front, switch all channels to ANALOG.
you can find here a mapping i used with timecode control in traktor scratch pro 1 - it imported fine to traktor scratch pro 2:
