I’ve moved a project from 11 to 12 that was struggling to playback due to intensive plugins on the project. I’m glad to report 12 now has got plenty of CPU performance to play with and the project is working comfortably. However exporting the mixdown seems to be taking about 80% extra time to complete, which is a bid odd.
On the export subject is there any detailed info on how sidechain inputs are now available to tracks when exported? Is this done by default or is there a setting?
