Logic Pro X "Preventing Sleep"

Question

Logic Pro X "Preventing Sleep"

My Mac Pro will not fall asleep automatically in Yosemite when Logic Pro X is running.

I've tested it, and Logic is definitely the problem. As you can see below, Activity Monitor also lists Logic X as "Preventing Sleep".

I can put the computer to sleep manually while running Logic, but not automatically.

This used to work. I suspect a Logic update may have caused this issue but I'm not sure.

Any idea how I can rectify this? Is there any chance an update to El Capitan might fix it?

Many thanks

Perhaps it's something they wired into Logic.

Logic has a history of losing the audio connection to pro & semi-pro audio interfaces if/when the computer goes to sleep.
The result was either dead silence or a screeching white noise type sound. This problem was especially prevalent with USB audio interfaces.

Do you have a USB audio interface?
