How do I unlock audio files in Logic Pro X?
With earlier versions of Logic, I used to be able to split audio files - in particular, recorded vocals - to increase or decrease the gain on specific notes or phrases if they were too quiet or too loud, relative to the rest of a recording I was happy with. But I can't seem to do that in Logic Pro X. Logic tells me the audio track is "locked", even if I split it, and therefore I can't change the gain. Nor can I separately normalize separate verses, choruses etc recorded on the same track, even when they have been separately recorded.
I can't find any reference to locking or unlocking audio files in the user guide. Splitting a file and converting to a new region or new audio file has no effect. It's driving me crazy!! Anyone got any suggestions?
Logic Pro X, OS X Mountain Lion (10.8.4)
