Classic general post that devolves into a personal argument. Love the internet.
Anyway, Thank you. It does happen randomly in tracks (new & old ) which doesn't help but at least I have some idea of what it might be.
It actually does the same thing using my Novation Xio as a sound card just playing back music on youtube etc so maybe the cpu is on it's way out.
To be honest things start it fall off when Apple leave you to far behind, so I'm going to start saving for a new one then I can shout at them for 12 months .
