Thanks Herb, but the Studio Fade-out is not linear. And I don't have a DAW other than RB and Audacity. I have not decided which way to go on purchasing a DAW ....
Those fades in my pic are linear..straight lines are linear fades.. Sonar gives you the choice of curved (Log) fades or straight line linear fades and you choose the rate for them all.
Some fades as you can see in my pic are faster than others. Some are simply "flip the switch" and very abrupt..... all depends on what I need.
That picture is showing the fades in the tracks.... I could also, just as easily fade from the master buss to get everything down at the same time. However, there are more times when I want certain things to fade before others. Doing it in the tracks like indicated, gives me that absolute control over the details that I don't have with a buss fade.
