Been at it for 2 Days tryin to sort out why I get bursts of white noise since I installed a UAD 1 card.No problems before although reading other posts it seems there may be a conflict between my Mbox and the newly installed card.Having tried everything I have read on this forum the problem still persists.I have emailed UAD with regard to this no answer yet.Anybody got any new suggestions Thanx Paddo.
