Hi again Prock,
Here’s what I have so far.
Firstly, I checked the knowledge base and trashed all the prefs.
This stopped the issue of not asking to save changes but didn’t solve the load time for mix console.
I then rendered the 5 tracks, closed the programme and reopened it, no difference.
Then I disabled the original tracks, closed the programme and bingo, problem gone away.
Just to double check, I then deleted the rendered tracks, enabled the originals, closed the programe, and the original mix console load time issue is back.
I figure it is obviously something to do with the Wave GTR plug so I need to do a bit more digging.
Thanks for your ideas and suggestions Prock, I’ll let you know how I get on.
