not in this session. sc4 can be funny at times, but i haven't had any

issues with it for quite a while. i don't have access to the session

atm, will ake a look when i return home on sunday. meanwhile, if you

want to pinpoint the problem, try muting all channels and then unmute

one by one.
do the nans crop up immediately, or only after playing some audio?
