I've been recording in the studio at 48khz/24 on a mac running protools 9. I want to do some additional tracks at home on my Sony Viao Windows 7 running protools 8. I've tried opening the session and it gives me messages about plug-ins not available, that's ok, but then it is playing slow. So, I tried making a new session at 48khz and importing the files but it's still slow. any ideas?
