Cubase Pro 8 & 8dio Hybrid Rhythms

Hi all,

anybody had this experience? I have been using Cubase Pro 8 for some time now and am very happy with it. Everything seems to work just fine but I am experiencing trouble with one VSti - 8dio Hybrid Rhythms. Every time I record a line and play it back it doesn’t play back correctly - sounds almost muted, just a slight dull sound of the original recording almost not to be heard… Anybody have a clue?
Thanks for your help,
