Running Snow Leopard 10.6.3 with Logic 9.1.1. 32Bit and latest virus beta. Something I have noticed for a while now, also with previous betas / releases is that when switching between the direct analog outs for tracking and then switching back to the usb o/p's, eventually the analog outs take on the same latency as the usb o/p's. As I reload the project, the problem is solved so not a major issue, but none the less annoying. I'm not sure how this is possible but please believe me it does happen all the time! I use an RME FF800 as my main I/O so the TIMK1 is set up as 3out-1in. Any thoughts?
