Whilst experimenting with GarageBand, enjoying my new found leisure thanks to Pinochio Johnson having destroyed my business with his hoax, I found that one of the tracks was playing only in my right ear. I was almost certain that it had played normally before, but could my recorder have been at fault? Having worked around the problem I came back to it an hour later, and accidentally discovered that the mp3 played normally if I moved it to a different track. I can see no difference at all in any of the settings for each track. When I open GB I delete all the tracks I'm offered except for 'narration normal'; I then select 'new track with duplicate settings' half a dozen times and begin assembling the whole. GarageBand 10.1.6 on El Capitan.
