The decay curve shape is not the same as the decay length, even though it might sound this way. The decay curve shape dictates in what way fades fade out. Many software synths and samplers fade things out in a linear way (x^1) whereas analog synthesizers tend to follow a more rapid slope (x^2). Here are a few examples of what the shapes look like:

Adjusting the decay curve shape parameter produces various logaritmic slopes. When the decay length is set to something long, the various curve shapes look as the above.

Adjusting the decay curve shape parameter produces various logaritmic slopes. When the decay length is set to something short, the various curve shapes look as the above.
