Oh, I’ve never read the manual 
Glad you’ve got it sorted. You can change the type of algorithm it uses in the Pool too to minimise nasty effects. Also I think if you bounce down then it might even apply a more accurate algorithm than the real-time version (but best check, that could be old info!!). Well, at least bouncing stops and random processing fluctuations, which I’ve noticed in the past with real-time processing…
