Hello All, I have two Macs: 1) MacPro dual Xeon, 2.66 with 18g of RAM, 2) MBP 15 core i7 with 8g of RAM. I've noticed since updating both computers to Lion that if I have a plug in window open, like say Ozone 5 and logic is playing that I pretty much can't do a darn thing. I'm talking 3-4 second latency on pressing buttons. This is on my MacPro which is a fresh clean Lion install with only Lion drivers for my audio stuff. I don't do much work on the MBP15 for logic as it is mainly a travel work computer but I will play with logic there and see if I see the same issue. Prior to Lion I was very used to playing tracks, double click to bring up say Ozone and making adjustments as I listen. It seems with Lion this just doesn't work and its frustrating. Anybody else see the same thing or do I have a problem going on?
