No more Sync issues, heres how i did it :)

from my experience crackles seem to be a different issue to what this solves, unless you are specifically talking about when adjusting tempo?

what is your soundcard driver buffer size and are you using the virus as a soundcard or another device?

do you get any pitch warbling on the clocked delays and the arp changing its timing? because that's what this workaround got rid of for me and some others.
