### SOLUTION ###
I came up this thread will googling since I had the same issue.
The problem:
All out of sudden, an audio track was delayed by about 0.2 seconds. It was perfect on grid in Logic. Other tracks work fine.
The solution:
- It seems like there is a bug in logic with sidechain compressing.
- The problem began, after I made a sidechain bus from my kick to the bassline using the standard Logic compressor.
- I replicated the issue.
- Deleting the compressor out of the channel strip: Everything's perfect.
- Undo the deletion: Audio lag again.
I just registered now, to help you out. I hope it works for you too.
Best,
