Missing Master Track Settings
I'm running 10.10.2 on a mid-2011 iMac, and Logic Express 9.1.8.
In my mixer, the channel strip marked 'Master' usually has settings I can alter, but for some reason the channel strip has gone blank. I don't even have a 'Setting' button at the top that I can use to reset it.
I've read a bunch of threads on here where people had the same problem because one of their outputs got switched to 'Surround' by accident but I have checked every channel strip, and every single one is set to 'Stereo' including the Prelisten track (which I gather is the typical culprit).
Please can someone help me figure out how to get my Master channel strip working again? I attach a screenshot so you can see what sort of set up I'm working with. Right above where it says 'Master' there are usually slots for inserting effects (like Mastering presets), but as you can see it's completely blank. Also, I don't know where AUX 1 came from. Perhaps that's got something to do with it, because I don't remember creating or using any Aux channels during this project.
Many thanks!
iMac, OS X Yosemite (10.10.2)
