I was talking about the
MIDI Clock parameter which is a Config Parameter
AFAIK, it is set to
Sync to External by default, which is good setting for this...
You'll also find some parameters related with S/PDIF which are
Source and
Frequency.
Source is set to
Auto by default and this means the Virus will be synced to external audio clock. For
Frequency, try first
48.0 kHz and if that doesn't work (maybe it won't work), set it to
44.1 kHz and make sure to also set the Motu to that frequency.
