VST delay on playback

Firstly, I apologise if this question has been asked previously…

My problem is that I am experiencing a delay between an analogue recording and Halion Sonic SE. This is when I am playing back a voice recording using Halion sonic SE instruments as backing. The voice is always ahead of the VST backing.

This seem to be on playback only because when I export all the tracks to an mp3 or wav, the voice is exactly on time with the backing.

I am using a Cubase 7.0.1(64bit) on MacBook Pro with Edirol FA66.

I didn’t have this problem using Cubase 7.0.0 before. Is there a tweak that I need to do on the 7.0.1?
