I only upgraded to 7 because I get a Low Memory warning when I use more than 11 in a full session. I was praying that they fixed it. They didn't The new AT 7 is even worse.
On a empty session if I go beyond 22 tracks it will crash. Try for yourself
I emailed there support and have heard no response.
Here are some videos I made showing the errors and crashes
