I realize that's pretty vague. Sorry. I was exporting a song into individual tracks. A yellow box in the lower right-hand corner popped up but disappeared before I could read it completely. It said I might like to go into preferences and enable something that would make the tracks blended together better but it might slow down rendering.
This was one audiophile 2019 I just got 2020 but have not plugged it in quite yet. That feature might be standard in 2020. Anybody know what I'm talking about?
