Aether, thanks for your reply.
The Virus can't be slaved over SPDIF, thats fact.
Well, if it has the option to be slaved, it should work properly, shouldn't it? I'm going to record an example of the artifacts and ask Access support. Anyway, good to know it's not only my unit's fault.

You can still slave your clock to the Virus, in other words is your Virus the masterclock and all other devices receives its clock-signal.
I tried slaving my soundcard to the Virus, but it didn't work - as in, I got no sound at all.

Alternative you can use VC and slave your Virus to your sequencer over USB.
I mostly use VC in Live mode, so I still need to connect Virus' outputs (digital or analog) to the soundcard. Or do you mean the USB connection provides an external clock for the Virus?

Your sequencer should be slaved to your soundcard.
What do you mean by that? AFAIK, the sequencer tells the soundcard what sample rate it wants to use (I stick to 44.1 btw) and then just keeps feeding it audio buffers. With all this happening automatically, how can I "slave" it?
