[Sonar X1] Control the "curve level" of Curved Envelopes in automation?

Thanks both of you for your answers, but the method suggested by Guitarhacker is not an option for me cuz it takes too much manual work but the result is still not as "fine" as from the Envelope showed in the picture of post #1. Anyway, I wish Sonar had the option to control the "curve level" as allowed in some other DAWs... I wonder if you can do it in Sonar X2? Or you just have to draw it manually like in X1, like garrigus said? Btw, thanks garrigus :D

Our ability to differentiate between volume envelope shapes depends on how fast the change is. If the change is short, less than 20ms or so, then you can't really hear any difference. Just use linear curves for those. You only need to get fancy with automation curves when the transition happens over a long period, more than a second or two in duration. Even then, it's unlikely that it needs to be anything fancier than a combination of slow and fast curves.
 
A useful fourth slope option is the "S" curve. That's where the level rises quickly in the first portion and then less quickly for the second portion (or vice versa). It's not a built-in option, but it's very easy to create such a curve by simply adding a node to split the curve into two parts.
 
Between the slow, fast and "S" curves you've pretty much got it covered. These are the most natural-sounding curves that most accurately model amplitude changes as we hear them in the acoustical world.
 
For those rare occasions when you really do need a fancy curve, build it out of slow and fast segments (or draw it in, although I've never found it necessary to do that, and believe me I am Mr. Automation!).

Wouldn't it be great if we had another option where the envelope starts as linear but had a grabber in the center so you can adjust the curve to your liking?
