hey there Arron. it doesn't actually work as a "normal" vst. in fact, its just recently started working with X2 very well at all.
you have to insert it on an audio track (im sure you know that already) and then let sonar loop (say 4 measures over and over) to hear it in action.
what this does is it turns on the audio engine in sonar.
from there, it works pretty much just like stand alone.
