Someone please put me out of my misery! I double click on an audio region, I am in the sample editor. I click the Factory menu but the time and pitch machine, the groove machine, The Audio Energizer and the Silencer are all greyed out. I have checked the manual and there is no suggestion as to what I am doing wrong. Any suggestions are more than apreciated.

It's an .aif file. I am dragging it into the arrange window from my desktop, then double clicking on it to access the sample editor. Then its greyed out. Cheers for your help so far guys. I have just tried exactly the same on Logic 8 on my laptop and it works fine. The problem is doing it on Express7.

I have managed to do it in the past though. A real mystery!
